관련 step: AI 호출 결과의 결정론적 재사용 — content-addressed cache
source: 신규 axis (2026-05-21 사용자 제안)
roadmap axis: R3 (AI 보정/재구성 보조)
wave: 1 (실질 구동 도달 필수)
priority: ★ IMP-33 짝
pair: IMP-33 (AI 호출 실선) — 같이 작업
dependency: IMP-33 의 AI hook

scope:

• AI 호출 직전/직후에 cache lookup/save layer
• 저장 위치: data/frame_cache/{frame_id}/{signature_hash}.json
• Cache key (signature): frame_id + v4_label + cardinality + source_shape (table/bullet/paragraph) + h3 갯수 + 글자수 bucket + layout preset + zone position
• Cache value: AI 가 생성한 builder_options + partial_overrides + slot mapping (+ slide-level CSS 있으면)
• Lookup: signature 완전 일치 (1차) → fuzzy match (2차, 옵션)
• Save: visual_check PASS AND 사용자 OK (or --auto-cache flag)
• Invalidation: frame contract 변경 / partial template 변경 / catalog 업데이트 → 해당 frame cache 폐기

out of scope:

• AI 호출 자체 → IMP-33
• catalog 정식 promote (cache → catalog 승격) → 추후 R4 (DB 운영) 영역

guardrail / validation:

• ★ Cache 저장 조건 = visual_check PASS + 사용자 OK 후만
• ★ contract/partial 변경 시 invalidate (cache 일관성)
• no-hardcoding: signature hash 가 sample-specific case 만들지 않게
• cache hit 결과 = 결정론적 (같은 input → 같은 output)
• AI 격리 contract 부합 (cache 도 fallback path 결과만 저장)

cross-ref:

• pair: IMP-33
• depend: IMP-33 의 AI hook
• consumer: 모든 IMP-33 호출 시점 (자동 lookup)
• backlog 보류: cache → catalog promote 기능 (운영 단계 R4)

review loop:

• Codex 1차 review
• Claude 재검토
• Codex 재검증
• scope-locked
• ready-for-implementation
• implemented
• verified

[Claude #1] Stage 1 problem-review — IMP-46

1. Source re-read + pair context

• source axis = #62 (frame transformation cache layer — content-addressed cache; lookup before AI call + save after visual_check PASS + 사용자 OK or --auto-cache).
• pair = #61 IMP-33 (closed at c864fe0, AI fallback scaffolding u1~u11, flag default OFF). IMP-33 already shipped a u6 cache stub + a u8 step12 cache_key build site that is sample-specific. IMP-46 = replace the stub backend AND fix the key.
• depend = IMP-33 AI hook (now landed); declared consumer = every route_ai_fallback call site (currently only gather_step12_ai_repair_proposals).
• out-of-scope (explicit) = AI call itself (IMP-33), cache → catalog promotion (R4).
• roadmap axis = R3 (AI 보정/재구성 보조), wave 1 (실질 구동 필수).

2. Root cause — what IMP-33 stub left unfinished (3-axis)

Axis A — u6 cache backend = NotImplementedError marker

src/phase_z2_ai_fallback/cache.py:79-82 (verified):

raise NotImplementedError(
    "IMP-46 persistent cache storage is not implemented yet; "
    "this is the IMP-33 u6 stub marker."
)

read_proposal returns None for any key (cache.py:36-45); save_proposal enforces both gates then raises NotImplementedError (cache.py:48-82). IMP-46 = replace the marker with a real backend (read + write JSON under data/frame_cache/{frame_id}/{signature_hash}.json per issue spec). Gate semantics (visual_check_passed AND user_approved → write path) are already in place and must be preserved.

Axis B — u8 cache_key is sample-specific (the critical defect)

src/phase_z2_ai_fallback/step12.py:109-111 (verified):

cache_key = "::".join(
    [template_id, ",".join(sorted(record["source_section_ids"]))]
)

source_section_ids is the MDX section identifier (e.g., "02.mdx::sec-0"). This means:

• a fresh MDX with the same structural shape → guaranteed cache MISS;
• two MDX with different identifiers but identical signature → never hit;
• adding/renaming a sample → orphans the cache entry.

This defeats the cache's reason to exist. The whole point of feedback_no_hardcoding ("signature hash 가 sample-specific case 만들지 않게") is to make the key structural, not source-identifier-based.

Issue spec's required signature axes (verified against catalog + V4 evidence schema):

signature axis	source at HEAD	structural?
frame_id	frame_contracts.yaml per-template frame_id: (e.g. 1171281190) — templates/phase_z2/catalog/frame_contracts.yaml:23	yes
v4_label	V4 result label (light_edit / restructure) — passed as record["label"]	yes
cardinality	frame contract cardinality.strict OR V4 result cardinality_signature — frame_contracts.yaml:27-29	yes
source_shape	frame_contract.source_shape (top_bullets / paragraph / table) — frame_contracts.yaml:26	yes
h3_count	source MDX subsection count (derivable from unit.raw_content)	yes
char_count_bucket	discretized text length (e.g., <100, 100-300, 300-700, 700+)	yes
layout_preset	sidebar-right / two-column / hero-detail / single-column — Phase Z layout choice	yes
zone_position	top / bottom_l / bottom_r — zone topology position	yes

None of these axes carry sample-specific identifiers. All are derivable from V4 result + frame contract + the unit's shape (not its source path). Hash → short hex digest.

Axis C — invalidation surface (3 sources)

Issue spec: frame contract 변경 / partial template 변경 / catalog 업데이트 → 해당 frame cache 폐기. Verified sources at HEAD:

source	path	scope
frame contract	templates/phase_z2/catalog/frame_contracts.yaml (loaded by src/phase_z2_mapper.py:49 load_frame_contracts with _CATALOG_CACHE global)	per-template subtree
partial template (family)	templates/phase_z2/families/*.html (12 files at HEAD)	per-template file
partial template (frame)	templates/phase_z2/frames/*.html (2 files at HEAD: process_product_two_way.html, three_parallel_requirements.html)	per-template file
catalog update	structural changes to frame_contracts.yaml (added sub_zones, accepted_content_types, etc.)	global if structural

Two strategies under consideration (Stage 2 lock target):

• (I1) per-entry embedded fingerprint — each cache entry stores SHA-256 of: (a) its template subtree of frame_contracts.yaml, (b) the family/frame partial HTML it references. On read, recompute and compare; mismatch → miss + log; never serve stale.
• (I2) global manifest version — single counter bumped on any catalog/partial change. Simpler but coarse (one frame change invalidates everything).

Claude #1 preference = I1 — surgical, audit-clear, no manual counter maintenance, aligns with feedback_no_hardcoding (no global state coupling).

Axis D — cache value semantics (ambiguity in issue spec)

Issue spec cache value = builder_options + partial_overrides + slot mapping (+ slide-level CSS). Mapped to IMP-33 u2 schema (src/phase_z2_ai_fallback/schema.py:22-25):

issue spec field	u2 ProposalKind	reusability across samples
builder_options	BUILDER_OPTIONS_PATCH	high — structural (parser switch, knob value)
partial_overrides	PARTIAL_OVERRIDES	ambiguous — payload slots may contain text content
slot mapping	SLOT_MAPPING_PROPOSAL	high — content-unit → slot decision (no raw text)
slide-level CSS	NOT in IMP-33 u2 whitelist	out-of-scope under FORBIDDEN_KINDS (raw_css) — schema.py:28-30

The slide-level CSS branch is forbidden by IMP-33 schema (raw_css in FORBIDDEN_KINDS). Issue spec's parenthetical "(+ slide-level CSS 있으면)" cannot be honored without expanding the u2 forbidden list, which would re-open IMP-17 carve-out. Scope-lock: drop "slide-level CSS" from cache value.

The PARTIAL_OVERRIDES payload may contain text. Two interpretations:

• (D1) verbatim cache — store the AI proposal as-is (text included). Then signature MUST include a content fingerprint of the MDX text to avoid wrong-text false hits. This collapses cache hits to "same MDX" → no cross-sample generalization → cache hit rate ≈ re-render same file.
• (D2) structural cache — store only structural decisions (builder_options + slot-mapping structure). Text content NOT cached; on hit, AI is not re-called, but text re-flows through the deterministic pipeline using the cached structural decisions. Cross-sample generalization works.

Claude #1 reading: issue spec's "결정론적 재사용" + "signature hash 가 sample-specific case 만들지 않게" guardrails point to D2. Stage 2 must lock; Codex review needed.

3. Scope-lock proposal (binding boundaries — Stage 2 will refine)

(a) Behavior delta — what changes, what does NOT

axis	today (HEAD c864fe0)	after IMP-46
read_proposal(key)	returns None for any key (cache.py:42-45)	reads data/frame_cache/{frame_id}/{signature_hash}.json if present + fingerprint valid; else None
save_proposal(key, proposal, *, visual_check_passed, user_approved)	both gates → NotImplementedError; either gate False → AiFallbackCacheGateError	both gates True → JSON write at canonical path; gate semantics unchanged
step12 cache key	template_id::source_section_ids (sample-specific)	structural signature hash (frame_id + v4_label + cardinality + source_shape + h3_count + char_bucket + layout_preset + zone_position)
AiFallbackProposal schema (u2)	3 kinds (BUILDER_OPTIONS_PATCH / PARTIAL_OVERRIDES / SLOT_MAPPING_PROPOSAL); FORBIDDEN_KINDS includes raw_css	unchanged — IMP-46 does NOT expand the whitelist. Slide-level CSS dropped from cache value
route_ai_fallback flow (u7)	flag-off OR route-mismatch → None; else cache_read → prompt → client → validate	unchanged call shape. Cache read step now backed by real storage; cache hit → return validated proposal without API call
normal-path AI call count	0 (PZ-1 lock)	0 (locked). Cache only activates inside fallback path; flag default still OFF
user_approved signal source	placeholder kwarg in save_proposal (no producer yet)	new producer: pipeline slide_status.user_approved field OR --auto-cache CLI flag (single-shot per run) → propagated to caller
data/frame_cache/ directory	does NOT exist	created on first write; per-frame subdirectory ({frame_id}/)
AST isolation guard	tests/phase_z2_ai_fallback/test_ast_isolation.py (IMP-33 u10) — package may NOT import Phase Q / Kei / pipeline runtime symbols	unchanged — IMP-46 cache backend imports nothing new from Phase Q / Kei; only stdlib (json, hashlib, pathlib)
existing IMP-33 tests	9 tests in tests/phase_z2_ai_fallback/test_cache.py (gate enforcement, NotImplementedError marker)	gate tests preserved verbatim; NotImplementedError test deleted and replaced with persistent-storage tests (signature determinism, hit/miss, invalidation, write-path)

(b) Signature (the key novel surface)

def build_cache_signature(
    *,
    frame_id: str,            # frame_contract.frame_id (str)
    v4_label: str,            # "light_edit" | "restructure"
    cardinality: int,
    source_shape: str,        # "top_bullets" | "paragraph" | "table"
    h3_count: int,
    char_count_bucket: str,   # discretized: "<100" | "100-300" | "300-700" | "700+"
    layout_preset: str,       # "sidebar-right" | "two-column" | "hero-detail" | "single-column"
    zone_position: str,       # "top" | "bottom_l" | "bottom_r"
) -> str:
    """Return short SHA-256 hex digest (16 chars) of the canonical-form tuple."""

Bucket boundaries MUST be declared in src/config.py (no inline literals) so future widening is anchor-driven. Stage 2 lock target.

(c) Cache entry schema (the persisted JSON)

{
  "schema_version": 1,
  "signature": "<16-char hex>",
  "signature_axes": {
    "frame_id": "1171281190",
    "v4_label": "light_edit",
    "cardinality": 3,
    "source_shape": "top_bullets",
    "h3_count": 3,
    "char_count_bucket": "100-300",
    "layout_preset": "two-column",
    "zone_position": "top"
  },
  "fingerprints": {
    "frame_contract_subtree_sha256": "...",
    "partial_template_sha256": "..."        // null if no partial referenced
  },
  "proposal": { "proposal_kind": "...", "payload": { ... }, "rationale": "..." },
  "created_at_utc": "2026-05-21T07:23:11Z",
  "visual_check_passed": true,
  "user_approved": true,
  "auto_cache_flag": false
}

Stored at data/frame_cache/{frame_id}/{signature}.json. On read: load → verify fingerprints.frame_contract_subtree_sha256 matches current catalog subtree → verify fingerprints.partial_template_sha256 matches current partial template content → if mismatch, return None and log invalidation reason. Pydantic schema validation on parse.

(d) Save trigger flow

Currently no site calls save_proposal. IMP-46 introduces the producer:

pipeline render → visual_check (existing, src/phase_z2_classifier.py:495)
                → user approval gate (new; settings.ai_fallback_auto_cache OR explicit slide_status.user_approved)
                → if both True AND proposal exists: save_proposal(signature, proposal, ...)

Save site = a new orchestration helper called from the pipeline AFTER slide_status.visual_check_passed and AFTER the (existing) user-OK signal. Stage 2 must lock the exact wiring point. Candidate site: end of phase_z2_pipeline.run_pipeline post-visual-check loop.

(e) --auto-cache flag

Issue spec mentions --auto-cache as user_approved bypass. Plumbing: new src/config.py Settings field ai_fallback_auto_cache: bool = False, env-overridable. Effective user_approved = (slide_status.user_approved OR settings.ai_fallback_auto_cache).

Default OFF — preserves the gate's safety meaning. CI runs with default OFF → no cache writes happen on CI.

(f) Invalidation triggers (Stage 2 lock target)

• on-read (mandatory) — fingerprint comparison; mismatch → miss.
• on-write (mandatory) — embed current fingerprints in entry.
• on-catalog-change (deferred to R4) — explicit purge command; out-of-scope for IMP-46.

4. Guardrails (Stage 2 binding)

#	guardrail	source
G1	normal-path AI call count = 0. Cache only operates inside fallback path; cache miss + flag-OFF route = no AI call	feedback_ai_isolation_contract, PZ-1, IMP-17-CARVE-OUT.md
G2	signature MUST be structural only — NO source_section_ids / NO MDX file path / NO sample identifier in signature input. Verified via unit test that 2 samples with different identifiers but identical structural axes produce the SAME signature	feedback_no_hardcoding, issue spec "signature hash 가 sample-specific case 만들지 않게"
G3	cache hit = deterministic — same signature MUST return byte-identical proposal across runs (test: read same entry twice + json.loads().model_dump() == ...)	issue spec "cache hit 결과 = 결정론적"
G4	save gate = visual_check_passed AND (user_approved OR auto_cache_flag). Existing AiFallbackCacheGateError semantics preserved	cache.py:69-78, issue spec
G5	invalidation on partial / contract change — read-time fingerprint comparison; on mismatch, return None and log reason. No serving stale entries	issue spec "contract/partial 변경 시 invalidate"
G6	slide-level CSS out of cache value — raw_css is in IMP-33 u2 FORBIDDEN_KINDS (schema.py:28-30); IMP-46 does NOT expand the whitelist	feedback_ai_isolation_contract, IMP-17 carve-out
G7	AST isolation preserved — IMP-46 cache backend imports ONLY stdlib (json, hashlib, pathlib) + IMP-33 u2 schema. NO Phase Q / Kei / pipeline runtime imports. Verified via test_ast_isolation.py rerun	IMP-33 u10 contract
G8	data/frame_cache/ MUST be gitignored or under explicit .gitignore rule (cache is runtime artifact, not source-of-truth). Catalog promotion (cache → committed) deferred to R4	issue spec "cache → catalog promote = R4"
G9	no-hardcoding — bucket boundaries, signature axis list, fingerprint sources ALL in src/config.py or catalog. No sample-specific (mdx 03/04/05) branches in cache module	RULE 0, feedback_no_hardcoding
G10	u8 step12 cache_key build site MUST be updated to call the new build_cache_signature helper. Leaving template_id::source_section_ids would render IMP-46 inert	Axis B above
G11	RULE 0 — signature axes evaluated against ALL 32 frames + ALL aligned MDX shapes. No frame-specific branching in signature builder	RULE 0 PIPELINE-CONSTRUCTION
G12	auto_cache_flag default False at HEAD merge. CI default preserves zero-write behavior	safety + IMP-33 default-OFF symmetry
G13	docstring + IMP-17/IMP-31 doc sync — cache.py module docstring updated (NotImplementedError marker removed); IMP-17-CARVE-OUT.md:54 IMP-46 row updated from "stub" to "active backend, gate semantics preserved"	doc-sync, anchor sync
G14	feedback_auto_pipeline_first — no review_required injection between AI call and cache save. Save gate decision is auto (visual_check + user_approved/auto_cache); failure paths emit clear reason strings, not queues	feedback_auto_pipeline_first
G15	post-IMP-46 backlog row in PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md added with status close + reference to commit. Currently stale (IMP-33/IMP-46 rows missing — already flagged in #61 Stage 1)	anchor sync

5. Implementation slicing sketch (Stage 2 input — NOT binding)

Suggested wave-1 ordering:

1. U1 — Config plumbing (zero behavior change)

   • src/config.py Settings : ai_fallback_auto_cache: bool = False, ai_fallback_cache_bucket_boundaries: tuple = (100, 300, 700) (declared values, env-overridable).
   • .env.example update; no committed .env.

2. U2 — Signature builder + axes

   • New module src/phase_z2_ai_fallback/cache_signature.py (stdlib only).
   • build_cache_signature(...) → 16-char SHA-256 hex.
   • bucket_char_count(n: int, boundaries: tuple[int, ...]) -> str helper.
   • Tests: determinism (same input → same hash), axis sensitivity (each axis change → different hash), cross-sample collision (2 different source_section_ids with same structural axes → same hash).

3. U3 — Fingerprint helpers

   • src/phase_z2_ai_fallback/cache_fingerprint.py — fingerprint_frame_contract_subtree(template_id) -> str, fingerprint_partial_template(template_id) -> str | None.
   • Tests: stable across reads; sensitive to catalog edit; None when no partial.

4. U4 — Persistent backend (replaces NotImplementedError)

   • Update src/phase_z2_ai_fallback/cache.py — read_proposal reads JSON from data/frame_cache/{frame_id}/{signature}.json; save_proposal writes JSON (still gated by the existing visual_check_passed AND user_approved conditions).
   • Path resolver respects frame_id axis (subdirectory).
   • Tests: round-trip read/write, invalidation on fingerprint mismatch, gate enforcement preserved (existing 6 gate tests must still pass).

5. U5 — Step12 integration

   • src/phase_z2_ai_fallback/step12.py:109-111 — replace sample-specific cache_key with build_cache_signature(...) using V4 result + frame contract + unit shape.
   • Add axis derivation helpers (h3 count, char count bucket, layout preset, zone position).
   • Tests: 2 samples × same shape × different identifiers → same signature → cache hit on 2nd run.

6. U6 — Save site

   • New helper apply_fallback_save_decision(slide_status, proposal, ...) -> None in src/phase_z2_ai_fallback/save_site.py (or pipeline-side module).
   • Called from pipeline after visual_check + user_approval.
   • Honors --auto-cache flag via config.
   • Tests: visual_check False → no write; user_approved False AND auto_cache False → no write; both True (or auto_cache True) → JSON written at canonical path.

7. U7 — .gitignore + invalidation log

   • Add data/frame_cache/ to .gitignore.
   • Optional: emit invalidation reason to debug.json (cache_invalidation_log additive field).

8. U8 — Tests + AST isolation rerun

   • Full tests/phase_z2_ai_fallback/ rerun (existing 116 tests must pass).
   • New tests under tests/phase_z2_ai_fallback/test_cache_persistent.py.
   • AST isolation guard rerun against new modules.

9. U9 — Docs sync

   • cache.py module docstring update.
   • IMP-17-CARVE-OUT.md:54 IMP-46 row update.
   • IMP-31-GATE-AUDIT.md (if any cache reference).
   • PHASE-Z-PIPELINE-STATUS-BOARD.md (IMP-46 line).
   • PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md row add.

6. Open questions (Codex round 1차 review)

• Q1 — Cache value semantics: D1 (verbatim, text included) vs D2 (structural only, text re-flowed)? Claude #1 preference = D2 (cross-sample generalization, no hidden text leak). Codex view?
• Q2 — Invalidation strategy: I1 (per-entry embedded fingerprint) vs I2 (global manifest counter)? Claude #1 preference = I1 (surgical, audit-clear).
• Q3 — --auto-cache flag plumbing: settings (env / .env) vs CLI argument vs both? Claude #1 strawman = settings only (env-overridable). CLI-only adds new arg-parser surface.
• Q4 — Signature axis list completeness: are 8 axes (frame_id / v4_label / cardinality / source_shape / h3_count / char_count_bucket / layout_preset / zone_position) sufficient? Should internal_region_id be added (Layer A SPEC v1 surface)? Claude #1 view: leave for v2; today Internal Region is trace-only.
• Q5 — Save site placement: end of pipeline run_pipeline post-visual-check vs separate explicit save_fallback_proposals(...) helper invoked by caller? Claude #1 preference = explicit helper (clearer audit + composability with --auto-cache).
• Q6 — Char count bucket boundaries: (100, 300, 700) vs other? Stage 2 lock target. Claude #1 strawman based on typical Korean text density at 16px / 600px-wide zones.
• Q7 — Hash truncation: 16-char SHA-256 hex (default) vs longer? Collision probability at 16 chars ≈ 2^-64; for 1k frames × 10 v4_labels × 8 cardinalities ≈ 80k entries → negligible. Claude #1 preference = 16.
• Q8 — Should IMP-46 also fix the symbolic cache_key parameter type at route_ai_fallback(cache_key: str, ...) in src/phase_z2_ai_fallback/router.py:45? Today the router treats it as opaque string; with structural signature, type stays str (no shape change). Claude #1 view: no router-side change required; signature build happens caller-side (step12) and passes the result.
• Q9 — Pair atomicity: IMP-46 in single PR vs split (signature first, backend second)? Claude #1 preference = single PR with u1~u9 (atomic; gates preserved).

FINAL_CONSENSUS: YES

[Claude #1] Stage 1 problem-review — IMP-46 ## 1. Source re-read + pair context - source axis = #62 (frame transformation cache layer — content-addressed cache; lookup before AI call + save after `visual_check PASS + 사용자 OK` or `--auto-cache`). - pair = #61 IMP-33 (closed at `c864fe0`, AI fallback scaffolding u1~u11, flag default OFF). IMP-33 already shipped a **u6 cache stub** + a **u8 step12 cache_key build site** that is sample-specific. IMP-46 = replace the stub backend AND fix the key. - depend = IMP-33 AI hook (now landed); declared consumer = every `route_ai_fallback` call site (currently only `gather_step12_ai_repair_proposals`). - out-of-scope (explicit) = AI call itself (IMP-33), cache → catalog promotion (R4). - roadmap axis = R3 (AI 보정/재구성 보조), wave 1 (실질 구동 필수). ## 2. Root cause — what IMP-33 stub left unfinished (3-axis) ### Axis A — u6 cache backend = NotImplementedError marker `src/phase_z2_ai_fallback/cache.py:79-82` (verified): ```python raise NotImplementedError( "IMP-46 persistent cache storage is not implemented yet; " "this is the IMP-33 u6 stub marker." ) ``` `read_proposal` returns `None` for any key (`cache.py:36-45`); `save_proposal` enforces both gates then raises NotImplementedError (`cache.py:48-82`). IMP-46 = replace the marker with a real backend (read + write JSON under `data/frame_cache/{frame_id}/{signature_hash}.json` per issue spec). Gate semantics (visual_check_passed AND user_approved → write path) are already in place and must be preserved. ### Axis B — u8 cache_key is sample-specific (the critical defect) `src/phase_z2_ai_fallback/step12.py:109-111` (verified): ```python cache_key = "::".join( [template_id, ",".join(sorted(record["source_section_ids"]))] ) ``` `source_section_ids` is the MDX section identifier (e.g., `"02.mdx::sec-0"`). This means: - a fresh MDX with the same structural shape → guaranteed cache MISS; - two MDX with different identifiers but identical signature → never hit; - adding/renaming a sample → orphans the cache entry. This defeats the cache's reason to exist. The whole point of `feedback_no_hardcoding` ("signature hash 가 sample-specific case 만들지 않게") is to make the key **structural**, not source-identifier-based. Issue spec's required signature axes (verified against catalog + V4 evidence schema): | signature axis | source at HEAD | structural? | |---|---|---| | `frame_id` | `frame_contracts.yaml` per-template `frame_id:` (e.g. `1171281190`) — `templates/phase_z2/catalog/frame_contracts.yaml:23` | yes | | `v4_label` | V4 result `label` (`light_edit` / `restructure`) — passed as `record["label"]` | yes | | `cardinality` | frame contract `cardinality.strict` OR V4 result `cardinality_signature` — `frame_contracts.yaml:27-29` | yes | | `source_shape` | `frame_contract.source_shape` (`top_bullets` / `paragraph` / `table`) — `frame_contracts.yaml:26` | yes | | `h3_count` | source MDX subsection count (derivable from `unit.raw_content`) | yes | | `char_count_bucket` | discretized text length (e.g., `<100`, `100-300`, `300-700`, `700+`) | yes | | `layout_preset` | `sidebar-right` / `two-column` / `hero-detail` / `single-column` — Phase Z layout choice | yes | | `zone_position` | `top` / `bottom_l` / `bottom_r` — zone topology position | yes | None of these axes carry sample-specific identifiers. All are derivable from V4 result + frame contract + the unit's shape (not its source path). Hash → short hex digest. ### Axis C — invalidation surface (3 sources) Issue spec: `frame contract 변경 / partial template 변경 / catalog 업데이트 → 해당 frame cache 폐기`. Verified sources at HEAD: | source | path | scope | |---|---|---| | frame contract | `templates/phase_z2/catalog/frame_contracts.yaml` (loaded by `src/phase_z2_mapper.py:49 load_frame_contracts` with `_CATALOG_CACHE` global) | per-template subtree | | partial template (family) | `templates/phase_z2/families/*.html` (12 files at HEAD) | per-template file | | partial template (frame) | `templates/phase_z2/frames/*.html` (2 files at HEAD: `process_product_two_way.html`, `three_parallel_requirements.html`) | per-template file | | catalog update | structural changes to `frame_contracts.yaml` (added `sub_zones`, `accepted_content_types`, etc.) | global if structural | Two strategies under consideration (Stage 2 lock target): - **(I1) per-entry embedded fingerprint** — each cache entry stores SHA-256 of: (a) its template subtree of `frame_contracts.yaml`, (b) the family/frame partial HTML it references. On read, recompute and compare; mismatch → miss + log; never serve stale. - **(I2) global manifest version** — single counter bumped on any catalog/partial change. Simpler but coarse (one frame change invalidates everything). Claude #1 preference = **I1** — surgical, audit-clear, no manual counter maintenance, aligns with `feedback_no_hardcoding` (no global state coupling). ### Axis D — cache value semantics (ambiguity in issue spec) Issue spec cache value = `builder_options + partial_overrides + slot mapping (+ slide-level CSS)`. Mapped to IMP-33 u2 schema (`src/phase_z2_ai_fallback/schema.py:22-25`): | issue spec field | u2 ProposalKind | reusability across samples | |---|---|---| | `builder_options` | `BUILDER_OPTIONS_PATCH` | high — structural (parser switch, knob value) | | `partial_overrides` | `PARTIAL_OVERRIDES` | **ambiguous** — payload `slots` may contain text content | | `slot mapping` | `SLOT_MAPPING_PROPOSAL` | high — content-unit → slot decision (no raw text) | | `slide-level CSS` | NOT in IMP-33 u2 whitelist | **out-of-scope under FORBIDDEN_KINDS (`raw_css`)** — `schema.py:28-30` | **The slide-level CSS branch is forbidden by IMP-33 schema** (`raw_css` in `FORBIDDEN_KINDS`). Issue spec's parenthetical "(+ slide-level CSS 있으면)" cannot be honored without expanding the u2 forbidden list, which would re-open IMP-17 carve-out. Scope-lock: **drop "slide-level CSS" from cache value**. The `PARTIAL_OVERRIDES` payload may contain text. Two interpretations: - **(D1) verbatim cache** — store the AI proposal as-is (text included). Then signature MUST include a content fingerprint of the MDX text to avoid wrong-text false hits. This collapses cache hits to "same MDX" → no cross-sample generalization → cache hit rate ≈ re-render same file. - **(D2) structural cache** — store only structural decisions (builder_options + slot-mapping structure). Text content NOT cached; on hit, AI is not re-called, but text re-flows through the deterministic pipeline using the cached structural decisions. Cross-sample generalization works. Claude #1 reading: issue spec's "결정론적 재사용" + "signature hash 가 sample-specific case 만들지 않게" guardrails point to **D2**. Stage 2 must lock; Codex review needed. ## 3. Scope-lock proposal (binding boundaries — Stage 2 will refine) ### (a) Behavior delta — what changes, what does NOT | axis | today (HEAD `c864fe0`) | after IMP-46 | |---|---|---| | `read_proposal(key)` | returns `None` for any key (`cache.py:42-45`) | reads `data/frame_cache/{frame_id}/{signature_hash}.json` if present + fingerprint valid; else `None` | | `save_proposal(key, proposal, *, visual_check_passed, user_approved)` | both gates → `NotImplementedError`; either gate False → `AiFallbackCacheGateError` | both gates True → JSON write at canonical path; gate semantics **unchanged** | | step12 cache key | `template_id::source_section_ids` (sample-specific) | structural signature hash (frame_id + v4_label + cardinality + source_shape + h3_count + char_bucket + layout_preset + zone_position) | | AiFallbackProposal schema (u2) | 3 kinds (`BUILDER_OPTIONS_PATCH` / `PARTIAL_OVERRIDES` / `SLOT_MAPPING_PROPOSAL`); FORBIDDEN_KINDS includes `raw_css` | **unchanged** — IMP-46 does NOT expand the whitelist. Slide-level CSS dropped from cache value | | `route_ai_fallback` flow (u7) | flag-off OR route-mismatch → None; else cache_read → prompt → client → validate | **unchanged** call shape. Cache read step now backed by real storage; cache hit → return validated proposal without API call | | normal-path AI call count | 0 (PZ-1 lock) | **0 (locked)**. Cache only activates inside fallback path; flag default still OFF | | user_approved signal source | placeholder kwarg in `save_proposal` (no producer yet) | new producer: pipeline `slide_status.user_approved` field OR `--auto-cache` CLI flag (single-shot per run) → propagated to caller | | `data/frame_cache/` directory | does NOT exist | created on first write; per-frame subdirectory (`{frame_id}/`) | | AST isolation guard | `tests/phase_z2_ai_fallback/test_ast_isolation.py` (IMP-33 u10) — package may NOT import Phase Q / Kei / pipeline runtime symbols | **unchanged** — IMP-46 cache backend imports nothing new from Phase Q / Kei; only stdlib (`json`, `hashlib`, `pathlib`) | | existing IMP-33 tests | 9 tests in `tests/phase_z2_ai_fallback/test_cache.py` (gate enforcement, NotImplementedError marker) | gate tests **preserved verbatim**; NotImplementedError test deleted and replaced with persistent-storage tests (signature determinism, hit/miss, invalidation, write-path) | ### (b) Signature (the key novel surface) ```python def build_cache_signature( *, frame_id: str, # frame_contract.frame_id (str) v4_label: str, # "light_edit" | "restructure" cardinality: int, source_shape: str, # "top_bullets" | "paragraph" | "table" h3_count: int, char_count_bucket: str, # discretized: "<100" | "100-300" | "300-700" | "700+" layout_preset: str, # "sidebar-right" | "two-column" | "hero-detail" | "single-column" zone_position: str, # "top" | "bottom_l" | "bottom_r" ) -> str: """Return short SHA-256 hex digest (16 chars) of the canonical-form tuple.""" ``` Bucket boundaries MUST be declared in `src/config.py` (no inline literals) so future widening is anchor-driven. Stage 2 lock target. ### (c) Cache entry schema (the persisted JSON) ```jsonc { "schema_version": 1, "signature": "<16-char hex>", "signature_axes": { "frame_id": "1171281190", "v4_label": "light_edit", "cardinality": 3, "source_shape": "top_bullets", "h3_count": 3, "char_count_bucket": "100-300", "layout_preset": "two-column", "zone_position": "top" }, "fingerprints": { "frame_contract_subtree_sha256": "...", "partial_template_sha256": "..." // null if no partial referenced }, "proposal": { "proposal_kind": "...", "payload": { ... }, "rationale": "..." }, "created_at_utc": "2026-05-21T07:23:11Z", "visual_check_passed": true, "user_approved": true, "auto_cache_flag": false } ``` Stored at `data/frame_cache/{frame_id}/{signature}.json`. On read: load → verify `fingerprints.frame_contract_subtree_sha256` matches current catalog subtree → verify `fingerprints.partial_template_sha256` matches current partial template content → if mismatch, return `None` and log invalidation reason. Pydantic schema validation on parse. ### (d) Save trigger flow Currently no site calls `save_proposal`. IMP-46 introduces the producer: ``` pipeline render → visual_check (existing, src/phase_z2_classifier.py:495) → user approval gate (new; settings.ai_fallback_auto_cache OR explicit slide_status.user_approved) → if both True AND proposal exists: save_proposal(signature, proposal, ...) ``` Save site = a new orchestration helper called from the pipeline AFTER `slide_status.visual_check_passed` and AFTER the (existing) user-OK signal. Stage 2 must lock the exact wiring point. Candidate site: end of `phase_z2_pipeline.run_pipeline` post-visual-check loop. ### (e) `--auto-cache` flag Issue spec mentions `--auto-cache` as user_approved bypass. Plumbing: new `src/config.py` Settings field `ai_fallback_auto_cache: bool = False`, env-overridable. Effective user_approved = `(slide_status.user_approved OR settings.ai_fallback_auto_cache)`. Default OFF — preserves the gate's safety meaning. CI runs with default OFF → no cache writes happen on CI. ### (f) Invalidation triggers (Stage 2 lock target) - **on-read** (mandatory) — fingerprint comparison; mismatch → miss. - **on-write** (mandatory) — embed current fingerprints in entry. - **on-catalog-change** (deferred to R4) — explicit purge command; out-of-scope for IMP-46. ## 4. Guardrails (Stage 2 binding) | # | guardrail | source | |---|---|---| | G1 | normal-path AI call count = **0**. Cache only operates inside fallback path; cache miss + flag-OFF route = no AI call | `feedback_ai_isolation_contract`, PZ-1, `IMP-17-CARVE-OUT.md` | | G2 | signature MUST be structural only — NO `source_section_ids` / NO MDX file path / NO sample identifier in signature input. Verified via unit test that 2 samples with different identifiers but identical structural axes produce the SAME signature | `feedback_no_hardcoding`, issue spec "signature hash 가 sample-specific case 만들지 않게" | | G3 | cache hit = deterministic — same signature MUST return byte-identical proposal across runs (test: read same entry twice + `json.loads().model_dump() == ...`) | issue spec "cache hit 결과 = 결정론적" | | G4 | save gate = visual_check_passed AND (user_approved OR auto_cache_flag). Existing `AiFallbackCacheGateError` semantics **preserved** | `cache.py:69-78`, issue spec | | G5 | invalidation on partial / contract change — read-time fingerprint comparison; on mismatch, return None and log reason. No serving stale entries | issue spec "contract/partial 변경 시 invalidate" | | G6 | slide-level CSS **out** of cache value — `raw_css` is in IMP-33 u2 `FORBIDDEN_KINDS` (`schema.py:28-30`); IMP-46 does NOT expand the whitelist | `feedback_ai_isolation_contract`, IMP-17 carve-out | | G7 | AST isolation **preserved** — IMP-46 cache backend imports ONLY stdlib (`json`, `hashlib`, `pathlib`) + IMP-33 u2 schema. NO Phase Q / Kei / pipeline runtime imports. Verified via `test_ast_isolation.py` rerun | IMP-33 u10 contract | | G8 | `data/frame_cache/` MUST be gitignored or under explicit `.gitignore` rule (cache is runtime artifact, not source-of-truth). Catalog promotion (cache → committed) deferred to R4 | issue spec "cache → catalog promote = R4" | | G9 | no-hardcoding — bucket boundaries, signature axis list, fingerprint sources ALL in `src/config.py` or catalog. No sample-specific (mdx 03/04/05) branches in cache module | RULE 0, `feedback_no_hardcoding` | | G10 | u8 step12 cache_key build site **MUST** be updated to call the new `build_cache_signature` helper. Leaving `template_id::source_section_ids` would render IMP-46 inert | Axis B above | | G11 | RULE 0 — signature axes evaluated against ALL 32 frames + ALL aligned MDX shapes. No frame-specific branching in signature builder | RULE 0 PIPELINE-CONSTRUCTION | | G12 | `auto_cache_flag` default **False** at HEAD merge. CI default preserves zero-write behavior | safety + IMP-33 default-OFF symmetry | | G13 | docstring + IMP-17/IMP-31 doc sync — `cache.py` module docstring updated (NotImplementedError marker removed); `IMP-17-CARVE-OUT.md:54` IMP-46 row updated from "stub" to "active backend, gate semantics preserved" | doc-sync, anchor sync | | G14 | `feedback_auto_pipeline_first` — no `review_required` injection between AI call and cache save.

Currently stale (IMP-33/IMP-46 rows missing — already flagged in #61 Stage 1) | anchor sync | ## 5. Implementation slicing sketch (Stage 2 input — NOT binding) Suggested wave-1 ordering: 1. **U1 — Config plumbing (zero behavior change)** - `src/config.py` Settings : `ai_fallback_auto_cache: bool = False`, `ai_fallback_cache_bucket_boundaries: tuple = (100, 300, 700)` (declared values, env-overridable). - .env.example update; no committed .env. 2. **U2 — Signature builder + axes** - New module `src/phase_z2_ai_fallback/cache_signature.py` (stdlib only). - `build_cache_signature(...)` → 16-char SHA-256 hex. - `bucket_char_count(n: int, boundaries: tuple[int, ...]) -> str` helper. - Tests: determinism (same input → same hash), axis sensitivity (each axis change → different hash), cross-sample collision (2 different `source_section_ids` with same structural axes → same hash). 3. **U3 — Fingerprint helpers** - `src/phase_z2_ai_fallback/cache_fingerprint.py` — `fingerprint_frame_contract_subtree(template_id) -> str`, `fingerprint_partial_template(template_id) -> str | None`. - Tests: stable across reads; sensitive to catalog edit; None when no partial. 4. **U4 — Persistent backend (replaces NotImplementedError)** - Update `src/phase_z2_ai_fallback/cache.py` — `read_proposal` reads JSON from `data/frame_cache/{frame_id}/{signature}.json`; `save_proposal` writes JSON (still gated by the existing `visual_check_passed` AND `user_approved` conditions). - Path resolver respects `frame_id` axis (subdirectory). - Tests: round-trip read/write, invalidation on fingerprint mismatch, gate enforcement preserved (existing 6 gate tests must still pass). 5. **U5 — Step12 integration** - `src/phase_z2_ai_fallback/step12.py:109-111` — replace sample-specific `cache_key` with `build_cache_signature(...)` using V4 result + frame contract + unit shape. - Add axis derivation helpers (h3 count, char count bucket, layout preset, zone position). - Tests: 2 samples × same shape × different identifiers → same signature → cache hit on 2nd run. 6. **U6 — Save site** - New helper `apply_fallback_save_decision(slide_status, proposal, ...) -> None` in `src/phase_z2_ai_fallback/save_site.py` (or pipeline-side module). - Called from pipeline after visual_check + user_approval. - Honors `--auto-cache` flag via config. - Tests: visual_check False → no write; user_approved False AND auto_cache False → no write; both True (or auto_cache True) → JSON written at canonical path. 7. **U7 — `.gitignore` + invalidation log** - Add `data/frame_cache/` to `.gitignore`. - Optional: emit invalidation reason to `debug.json` (`cache_invalidation_log` additive field). 8. **U8 — Tests + AST isolation rerun** - Full `tests/phase_z2_ai_fallback/` rerun (existing 116 tests must pass). - New tests under `tests/phase_z2_ai_fallback/test_cache_persistent.py`. - AST isolation guard rerun against new modules. 9. **U9 — Docs sync** - `cache.py` module docstring update. - `IMP-17-CARVE-OUT.md:54` IMP-46 row update. - `IMP-31-GATE-AUDIT.md` (if any cache reference). - `PHASE-Z-PIPELINE-STATUS-BOARD.md` (IMP-46 line). - `PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md` row add. ## 6. Open questions (Codex round 1차 review) - **Q1 — Cache value semantics: D1 (verbatim, text included) vs D2 (structural only, text re-flowed)?** Claude #1 preference = D2 (cross-sample generalization, no hidden text leak). Codex view? - **Q2 — Invalidation strategy: I1 (per-entry embedded fingerprint) vs I2 (global manifest counter)?** Claude #1 preference = I1 (surgical, audit-clear). - **Q3 — `--auto-cache` flag plumbing: settings (env / .env) vs CLI argument vs both?** Claude #1 strawman = settings only (env-overridable). CLI-only adds new arg-parser surface. - **Q4 — Signature axis list completeness: are 8 axes (frame_id / v4_label / cardinality / source_shape / h3_count / char_count_bucket / layout_preset / zone_position) sufficient?** Should `internal_region_id` be added (Layer A SPEC v1 surface)? Claude #1 view: leave for v2; today Internal Region is trace-only. - **Q5 — Save site placement: end of pipeline `run_pipeline` post-visual-check vs separate explicit `save_fallback_proposals(...)` helper invoked by caller?** Claude #1 preference = explicit helper (clearer audit + composability with `--auto-cache`). - **Q6 — Char count bucket boundaries: (100, 300, 700) vs other?** Stage 2 lock target. Claude #1 strawman based on typical Korean text density at 16px / 600px-wide zones. - **Q7 — Hash truncation: 16-char SHA-256 hex (default) vs longer?** Collision probability at 16 chars ≈ 2^-64; for 1k frames × 10 v4_labels × 8 cardinalities ≈ 80k entries → negligible. Claude #1 preference = 16. - **Q8 — Should IMP-46 also fix the symbolic `cache_key` parameter type at `route_ai_fallback(cache_key: str, ...)` in `src/phase_z2_ai_fallback/router.py:45`?** Today the router treats it as opaque string; with structural signature, type stays `str` (no shape change). Claude #1 view: no router-side change required; signature build happens caller-side (step12) and passes the result. - **Q9 — Pair atomicity: IMP-46 in single PR vs split (signature first, backend second)?** Claude #1 preference = single PR with u1~u9 (atomic; gates preserved). === EVIDENCE === Files read (path:line): - `src/phase_z2_ai_fallback/cache.py` — full file (`read_proposal` returns None; `save_proposal` gates → NotImplementedError marker). - `src/phase_z2_ai_fallback/step12.py` — full file (`cache_key` build at L109-111 confirmed sample-specific). - `src/phase_z2_ai_fallback/router.py` — full file (cache_read at L66; no save call). - `src/phase_z2_ai_fallback/schema.py` — full file (3 ProposalKind values; `FORBIDDEN_KINDS` includes `raw_css`). - `src/phase_z2_ai_fallback/prompts.py` — full file (`V4_ROUTE_AI_ADAPTATION = "ai_adaptation_required"`; user payload structure). - `src/phase_z2_ai_fallback/validate.py` — full file (4 guards; payload may contain slot text under `PARTIAL_OVERRIDES`). - `src/phase_z2_ai_fallback/step17.py` L1-80 (overflow cascade order; AI_REPAIR stage definition). - `src/phase_z2_ai_fallback/__init__.py` — full file (exports = schema only; cache NOT re-exported). - `src/config.py` — full file (existing `ai_fallback_*` 8 fields; no `ai_fallback_auto_cache` yet). - `src/phase_z2_mapper.py` L1-80 (catalog loader at L49; `_CATALOG_CACHE` global; `CATALOG_PATH` at L34). - `templates/phase_z2/catalog/frame_contracts.yaml` L1-60 (single yaml; per-template `frame_id` + `source_shape` + `cardinality.strict`). - `tests/phase_z2_ai_fallback/test_cache.py` — full file (9 tests covering gate + NotImplementedError marker; 1 test must be replaced when backend lands). Grep / count results: - `grep -rn "frame_cache\|IMP-46\|cache_key" src/phase_z2_ai_fallback/` = 5 hits across `cache.py`, `router.py`, `step12.py`, `step17.py` (all consistent with stub status). - `grep -rn "visual_check_passed" src/` = 4 sites (`cache.py` × 4, `phase_z2_classifier.py:495` producer, `phase_z2_pipeline.py:2635/5086` consumer). Producer of `user_approved` = none today (new surface). - `grep -n "load_frame_contracts" src/phase_z2_mapper.py` = L49 (loader); `get_contract` at L56 (per-template subtree access). - `ls templates/phase_z2/frames/` = 2 files (`process_product_two_way.html`, `three_parallel_requirements.html`). - `ls templates/phase_z2/families/` = 12 family partials. - `ls data/` = no `frame_cache/` directory at HEAD (confirmed via `ls data/`). - `grep -rln "auto_cache\|--auto-cache" src/` = 0 (new surface). Commits cross-checked: - `c864fe0` (IMP-33 u1~u11) — current HEAD; cache stub landed. - `1efbf67` (IMP-30 first-render invariant) — provisional zone synthesis upstream of step12 cache_key build. - Pair issue #62 body (current task input) — signature axes + value scope + invalidation rules verified.

[Codex #1] Stage 1 problem-review - IMP-46

Status 3-axis:

1. Backend axis: verified. src/phase_z2_ai_fallback/cache.py:36 returns None for every valid key, and src/phase_z2_ai_fallback/cache.py:48 preserves the two write gates before raising the IMP-46 NotImplementedError at src/phase_z2_ai_fallback/cache.py:79. IMP-46 must replace this marker with persistent JSON read/write while preserving the visual_check and user_approved gates.

2. Signature axis: verified, with a scope correction. src/phase_z2_ai_fallback/step12.py:109 builds cache_key from template_id plus sorted source_section_ids; those IDs are source/sample identifiers, so structurally identical content with different MDX section IDs will miss. This violates the issue's no-hardcoding/content-addressed intent. The fix must introduce a deterministic structural signature hash using frame_id, v4 label, cardinality, source shape, h3 count, character-count bucket, layout preset, and zone position.

3. Integration/scope axis: scope is larger than a backend swap. src/phase_z2_ai_fallback/step12.py:32 does not accept layout_preset or zone_position, but both are required signature axes. src/phase_z2_ai_fallback/step12.py:113 also passes v4_result["cardinality"] = None, while src/phase_z2_ai_fallback/prompts.py:66 only reads cardinality/cardinality_signature if present. Stage 2 must choose a call/integration point where unit raw_content, frame contract, resolved layout preset, and zone position are all available, or extend the Step 12 helper contract explicitly.

Missing files / wrong assumptions flagged:

• No existing persistent cache was found: no data/frame_cache directory and no frame_cache/signature_hash implementation in src, templates, tests, or data.
• route_ai_fallback has one source call site, src/phase_z2_ai_fallback/step12.py:120; tests call it directly, but I found no production call to gather_step12_ai_repair_proposals outside tests. Do not assume the pipeline already invokes the Step 12 AI helper.
• Current frame contracts contain 32 frames and expose structural axes such as frame_id, source_shape, and cardinality in templates/phase_z2/catalog/frame_contracts.yaml, but source_shape values are currently repo terms such as top_bullets and h3_subsections, not only the issue text's table/bullet/paragraph. The signature builder should canonicalize from existing repo data rather than hardcoding sample-specific or issue-wording-specific labels.
• save_proposal is only called by tests today; the production write path after visual_check PASS plus user OK/--auto-cache still needs a concrete caller-owned integration point. The router intentionally imports only read_proposal, so write-after-approval must remain outside route_ai_fallback.
• Cache value scope should stay within the existing AiFallbackProposal contract (builder_options_patch, partial_overrides, slot_mapping_proposal) plus any slide-level CSS metadata only if represented as a validated/cache-owned extension. Raw HTML/CSS or frame changes remain forbidden by src/phase_z2_ai_fallback/schema.py and validation contracts.

Scope-lock recommendation:

Proceed to Stage 2 only if the plan includes: a content-addressed signature builder, persistent JSON storage at data/frame_cache/{frame_id}/{signature_hash}.json, exact lookup first and optional fuzzy lookup as a separate deterministic layer, guarded save semantics, invalidation tied to frame contracts/partials/catalog changes, and focused tests for deterministic key stability across different source_section_ids. No sample-specific MDX 03/04/05 keys should survive.

  FINAL_CONSENSUS: YES

[Codex #1] Stage 1 problem-review - IMP-46 Status 3-axis: 1. Backend axis: verified. `src/phase_z2_ai_fallback/cache.py:36` returns `None` for every valid key, and `src/phase_z2_ai_fallback/cache.py:48` preserves the two write gates before raising the IMP-46 `NotImplementedError` at `src/phase_z2_ai_fallback/cache.py:79`. IMP-46 must replace this marker with persistent JSON read/write while preserving the visual_check and user_approved gates. 2. Signature axis: verified, with a scope correction. `src/phase_z2_ai_fallback/step12.py:109` builds `cache_key` from `template_id` plus sorted `source_section_ids`; those IDs are source/sample identifiers, so structurally identical content with different MDX section IDs will miss. This violates the issue's no-hardcoding/content-addressed intent. The fix must introduce a deterministic structural signature hash using frame_id, v4 label, cardinality, source shape, h3 count, character-count bucket, layout preset, and zone position. 3. Integration/scope axis: scope is larger than a backend swap. `src/phase_z2_ai_fallback/step12.py:32` does not accept `layout_preset` or `zone_position`, but both are required signature axes. `src/phase_z2_ai_fallback/step12.py:113` also passes `v4_result["cardinality"] = None`, while `src/phase_z2_ai_fallback/prompts.py:66` only reads cardinality/cardinality_signature if present. Stage 2 must choose a call/integration point where unit raw_content, frame contract, resolved layout preset, and zone position are all available, or extend the Step 12 helper contract explicitly.

Per-unit rationale:

• u1: pure deterministic builder. q2 = fixed bins {0-50, 51-150, 151-400, 401-1000, 1001+}. q3 = enum {bullet, paragraph, table, mixed}. No section_id input — RULE 7 lock.
• u2: lands backend at IMP-33 u6 stub; preserves both gates; schema_version=1 (q4); cache_key stays {frame_id}::{signature_hash} so router signature untouched. Replaces test_save_raises_not_implemented with round-trip.
• u3: fingerprint = sha256 over {contract_sha, partial_sha, catalog_sha} (q5); read recomputes + treats mismatch as miss. No destructive sweep.
• u4: drops sample-specific cache_key; new kwargs propagate signature inputs + cardinality into v4_result (prompts.py:55-66 already optional-reads cardinality). Replaces test_cache_key_includes_template_and_section_ids with structural signature assertion.
• u5: flag-driven write-gate override; visual_check_passed remains mandatory. Default False keeps PZ-1 + AI-isolation intact.
• u6: data/frame_cache git-ignored with .gitkeep (q6); IMP-17 carve-out table refreshed to match landed behaviour.

Out of scope:

• AI call itself (IMP-33 c864fe0)
• Fuzzy match lookup (옵션, deferred)
• cache → catalog promotion (R4)
• New route_ai_fallback call sites beyond step12.py:120
• Stage 0 mdx_normalizer integration
• AI prompt redesign in prompts.py beyond cardinality propagation

Rollback: each unit single-commit revertable; u2/u3/u5 share cache.py → revert reverse order (u5→u3→u2); u1 + u6 additive and safely deletable.

    tests: []
    estimate_lines: 20

Per-unit rationale:

• u1: Covers the 8-axis exact structural signature and removes section/sample id leakage. Needs one explicit same-structure/different-section-id determinism test in Stage 3.
• u2: Backend path, schema_version, corrupt/missing miss behavior, and write gate are in scope. Plan is missing explicit cache value shape coverage for builder_options, partial_overrides, slot mapping, and optional slide-level CSS.
• u3: Invalidation axis is named, but not implementation-ready: the plan does not say where contract_sha, partial_sha, and catalog_sha are computed or how read_proposal receives/recomputes them. Unit files only cover cache.py tests, so integration with Step 12/router inputs is under-specified.
• u4: Structural key replacement and cardinality/layout/zone propagation are in scope. Plan does not cover exact-first lookup versus optional fuzzy lookup; fuzzy may be deferred, but the plan must say so and test exact deterministic hit behavior.
• u5: This does not satisfy the issue body as written. The issue asks for a --auto-cache flag; the plan only adds settings.ai_fallback_auto_cache and names no CLI/entrypoint file or existing flag surface.
• u6: Size/file-count rule passes. The .gitignore/.gitkeep choice is acceptable if generated JSON stays untracked and the directory anchor is tracked.

Out-of-scope notes:

• AI invocation internals, cache-to-catalog promotion, new route_ai_fallback call sites, and Stage 0 mdx_normalizer remain out of scope.
• Fuzzy lookup can be out of scope only if explicitly deferred as optional; current plan neither implements nor defers it.

Rollback strategy:

• Revert u1-u6 touched files and delete generated data/frame_cache JSON. No destructive sweep is required because cache misses fall back to the existing AI path.

  Test results:
• pytest -q tests: 526 passed in 41.83s
  Verified facts:
• Current cache.py read_proposal always returns None and save_proposal still raises NotImplementedError after both gates pass.
• Current step12.py builds cache_key from frame_template_id plus sorted source_section_ids, so the Stage 1 defect is real.
• Current router.py reads cache before prompt/client and does not import save_proposal.
• Current src/config.py has ai_fallback_enabled defaults but no ai_fallback_auto_cache field.

Needs one explicit same-structure/different-section-id determinism test in Stage 3. - u2: Backend path, schema_version, corrupt/missing miss behavior, and write gate are in scope. Plan is missing explicit cache value shape coverage for builder_options, partial_overrides, slot mapping, and optional slide-level CSS. - u3: Invalidation axis is named, but not implementation-ready: the plan does not say where contract_sha, partial_sha, and catalog_sha are computed or how read_proposal receives/recomputes them. Unit files only cover cache.py tests, so integration with Step 12/router inputs is under-specified. - u4: Structural key replacement and cardinality/layout/zone propagation are in scope. Plan does not cover exact-first lookup versus optional fuzzy lookup; fuzzy may be deferred, but the plan must say so and test exact deterministic hit behavior. - u5: This does not satisfy the issue body as written. The issue asks for a --auto-cache flag; the plan only adds settings.ai_fallback_auto_cache and names no CLI/entrypoint file or existing flag surface. - u6: Size/file-count rule passes. The .gitignore/.gitkeep choice is acceptable if generated JSON stays untracked and the directory anchor is tracked. Out-of-scope notes: - AI invocation internals, cache-to-catalog promotion, new route_ai_fallback call sites, and Stage 0 mdx_normalizer remain out of scope. - Fuzzy lookup can be out of scope only if explicitly deferred as optional; current plan neither implements nor defers it. Rollback strategy: - Revert u1-u6 touched files and delete generated data/frame_cache JSON. No destructive sweep is required because cache misses fall back to the existing AI path. === EVIDENCE === Commands run: - Get-Content D:\ad-hoc\kei\design_agent\.orchestrator\tmp\codex_prompt.txt - git status --short - rg over src/tests/docs for cache, Step 12, signature, and config surfaces - Get-Content src/phase_z2_ai_fallback/cache.py - Get-Content src/phase_z2_ai_fallback/step12.py - Get-Content src/phase_z2_ai_fallback/prompts.py - Get-Content src/phase_z2_ai_fallback/router.py - Get-Content src/phase_z2_ai_fallback/schema.py - Get-Content src/config.py - Get-Content tests/phase_z2_ai_fallback/test_cache.py - Get-Content tests/phase_z2_ai_fallback/test_step12.py - Get-Content tests/phase_z2_ai_fallback/test_router.py - Select-String docs/architecture/IMP-17-CARVE-OUT.md for cache/fallback anchors - pytest -q tests Files checked: - D:\ad-hoc\kei\design_agent\src\phase_z2_ai_fallback\cache.py - D:\ad-hoc\kei\design_agent\src\phase_z2_ai_fallback\step12.py - D:\ad-hoc\kei\design_agent\src\phase_z2_ai_fallback\prompts.py - D:\ad-hoc\kei\design_agent\src\phase_z2_ai_fallback\router.py - D:\ad-hoc\kei\design_agent\src\phase_z2_ai_fallback\schema.py - D:\ad-hoc\kei\design_agent\src\config.py - D:\ad-hoc\kei\design_agent\tests\phase_z2_ai_fallback\test_cache.py - D:\ad-hoc\kei\design_agent\tests\phase_z2_ai_fallback\test_step12.py - D:\ad-hoc\kei\design_agent\tests\phase_z2_ai_fallback\test_router.py - D:\ad-hoc\kei\design_agent\docs\architecture\IMP-17-CARVE-OUT.md Test results: - pytest -q tests: 526 passed in 41.83s Verified facts: - Current cache.py read_proposal always returns None and save_proposal still raises NotImplementedError after both gates pass. - Current step12.py builds cache_key from frame_template_id plus sorted source_section_ids, so the Stage 1 defect is real. - Current router.py reads cache before prompt/client and does not import save_proposal. - Current src/config.py has ai_fallback_enabled defaults but no ai_fallback_auto_cache field. - Existing tests assert the old sample-specific Step 12 cache key and the cache NotImplementedError marker, so Stage 3 must update those tests. - Claude r1 implementation_units block exists and every unit is <=50 estimated lines and <=3 files; size rule passes. rewind_target: stage_2_plan FINAL_CONSENSUS: NO

Per-unit rationale (Codex r1 gaps closed):

• u1: determinism test — same 8 axes / different section_ids → same hash; one-axis change → different hash.
• u2: cache value shape — proposal.payload holds all 3 ProposalKind variants; slide_css separate optional top-level. Miss+corrupt→None.
• u3: compute site = u4 caller. sha256(json.dumps(.,sort_keys=True)) for contract+partial, sha256(catalog_yaml.read_bytes()) for catalog. Cache stores opaquely; mismatch=None.
• u4: flow = sig→3 fp inline→read(sig,fp)→miss=router→visual+user_OK=save(sig,proposal,fp,gates). Deterministic-hit test added. Existing section-id assertion replaced.
• u5: real CLI surface (not settings-only). Gate truth table 2³=8 cells tested. visual_check_passed=False ALWAYS rejects.
• u6: ! exception keeps .gitkeep tracked; JSON untracked.

Out of scope:

• AI body (IMP-33 c864fe0); fuzzy lookup (deferred); cache→catalog (R4); new router call sites; Stage 0 normalizer; prompts.py redesign beyond cardinality.

Rollback:

• Per-unit revert. cache.py shared (u2/u3/u5) → reverse order. u1/u6 additive. Generated JSON gitignored — delete working tree only.

=== EVIDENCE ===

• cache.py:79-82 NotImplementedError marker; cache.py:36-45 read=None; cache.py:48-78 gates.
• step12.py:32 helper missing axes; step12.py:109-111 sample cache_key; step12.py:117 cardinality=None.
• prompts.py:65-66 cardinality optional-read (propagation safe).
• router.py:43-89 read-only, no save_proposal import (sig unchanged).
• config.py:19 no auto_cache field (u5 adds).

• .gitignore:11 data/ → u6 adds !data/frame_cache/.gitkeep.
• ls data/ → frame_cache/ absent (u6 creates).
• baseline pytest -q tests = 526 passed (Codex r1).

Verified: all units ≤50 lines + ≤3 files; Codex r1 NO gaps closed (u1 determinism, u2 value shape, u3 fp compute site, u4 exact-match decl + fuzzy deferred, u5 real CLI); rejected tests rewritten not deleted; flag defaults OFF; PZ-1 AI=0 intact.

[Codex #3] Stage 2 simulation-plan review - IMP-46

=== IMPLEMENTATION_UNITS ===

• id: u1
  summary: Add signature.py with deterministic SHA256 over the 8 declared structural axes: frame_id, v4_label, cardinality, source_shape, h3_count, char_count_bucket, layout_preset, zone_position. Use fixed char-count buckets 0-50, 51-150, 151-400, 401-1000, 1001+; source_shape enum bullet, paragraph, table, mixed; schema_version=1.

    tests:

    estimate_lines: 50
• id: u2
  summary: Replace cache.py NotImplementedError marker with persistent JSON backend at data/frame_cache/{frame_id}/{signature_hash}.json. Stored value includes schema_version, proposal, slide_css, fingerprints; missing/corrupt files return None; round-trip all ProposalKind values and slide_css None/set.

    tests:
  • tests/phase_z2_ai_fallback/test_cache.py
    estimate_lines: 50
• id: u3
  summary: Add invalidation by fingerprints: contract_sha, partial_sha, catalog_sha. save stores fingerprints, read compares supplied fingerprints and returns None on mismatch; fingerprint computation stays outside cache.py.
  files:
  • src/phase_z2_ai_fallback/cache.py
  • tests/phase_z2_ai_fallback/test_cache_invalidation.py
    tests:
  • tests/phase_z2_ai_fallback/test_cache_invalidation.py
    estimate_lines: 45
• id: u4
  summary: Extend Step 12 helper inputs for layout_preset, zone_position, source_shape, h3_count, char_count, cardinality; derive char_count_bucket via u1; compute the three fingerprints; replace template/section-id cache_key with structural signature. Exact-match lookup only; fuzzy is explicitly deferred as optional follow-up.
  files:
  • src/phase_z2_ai_fallback/step12.py
  • tests/phase_z2_ai_fallback/test_step12.py
    tests:
  • tests/phase_z2_ai_fallback/test_step12.py
    estimate_lines: 50
• id: u5
  summary: Add --auto-cache CLI flag in src/phase_z2_pipeline.py, wire settings.ai_fallback_auto_cache default False, and let save_proposal accept auto_cache. auto_cache bypasses user_approved only; visual_check_passed remains mandatory.
  files:

  • src/phase_z2_ai_fallback/cache.py
    tests:
  • tests/phase_z2_ai_fallback/test_cache.py
  • tests/test_phase_z2_ai_fallback_config.py
    estimate_lines: 40
• id: u6
  summary: Track data/frame_cache/.gitkeep by adding a .gitignore exception under the existing data/ ignore, and refresh IMP-17-CARVE-OUT.md cache row from stub status to persistent backend status.
  files:
  • .gitignore
  • data/frame_cache/.gitkeep
  • docs/architecture/IMP-17-CARVE-OUT.md
    tests: []
    estimate_lines: 20

Per-unit rationale:
u1 covers the no-hardcoding structural signature lock and removes source_section_id/sample leakage. Tests must assert same 8 axes produce same hash and any axis change changes it.
u2 covers the content-addressed persistent path and cache value shape. Tests must cover read miss, corrupt JSON miss, path creation, and ProposalKind round-trips.
u3 covers contract/partial/catalog invalidation without coupling cache.py to loaders. Tests must prove matching fingerprints hit and each mismatch misses.
u4 covers automatic lookup before the AI hook at the current production call site and supplies all missing signature inputs. Tests must prove router receives structural cache_key, not template plus section ids.
u5 covers the save gate and auto-cache override while preserving default OFF governance. Tests must prove visual_check is never bypassed.
u6 covers repo hygiene for the ignored data/ path and docs sync. No runtime test is needed; verify by git status and doc diff.

Out-of-scope notes:
AI invocation/client behavior remains IMP-33-owned and untouched; cache never invokes AI. Cache-to-catalog promotion remains R4. New route_ai_fallback call sites beyond Step 12 are excluded. Fuzzy lookup is optional and deferred; exact deterministic lookup is required for this stage.

Rollback strategy:
Revert the six unit file sets; remove data/frame_cache/.gitkeep and restore the data/ ignore-only state. This returns cache.py to IMP-33 stub behavior and Step 12 to its existing cache_key path.

  Test results:
• pytest -q tests: 526 passed in 42.03s
  Verified facts:
• cache.py still returns None on read and raises NotImplementedError after both gates, matching the IMP-46 target.
• step12.py still builds cache_key from template_id plus sorted source_section_ids and passes cardinality None, so u4 directly fixes the known defect.
• prompts.py reads cardinality/cardinality_signature only if present, so Step 12 contract extension is required.
• signature.py, test_signature.py, test_cache_invalidation.py, and data/frame_cache are absent now and correctly planned for Stage 3.
• .gitignore currently ignores data/ at line 11, so u6 needs an exception for data/frame_cache/.gitkeep.
• IMPLEMENTATION_UNITS exists; every unit is <= 50 estimated lines and <= 3 files.
• Side effects before posting: no source edits made for implementation; only this required draft artifact is created.

Tests must assert same 8 axes produce same hash and any axis change changes it. u2 covers the content-addressed persistent path and cache value shape. Tests must cover read miss, corrupt JSON miss, path creation, and ProposalKind round-trips. u3 covers contract/partial/catalog invalidation without coupling cache.py to loaders. Tests must prove matching fingerprints hit and each mismatch misses. u4 covers automatic lookup before the AI hook at the current production call site and supplies all missing signature inputs. Tests must prove router receives structural cache_key, not template plus section ids. u5 covers the save gate and auto-cache override while preserving default OFF governance. Tests must prove visual_check is never bypassed. u6 covers repo hygiene for the ignored data/ path and docs sync. No runtime test is needed; verify by git status and doc diff. Out-of-scope notes: AI invocation/client behavior remains IMP-33-owned and untouched; cache never invokes AI. Cache-to-catalog promotion remains R4. New route_ai_fallback call sites beyond Step 12 are excluded. Fuzzy lookup is optional and deferred; exact deterministic lookup is required for this stage. Rollback strategy: Revert the six unit file sets; remove data/frame_cache/.gitkeep and restore the data/ ignore-only state.

[Claude #3] Stage 2 simulation-plan IMP-46 (r2 — u6 test gap closed)

Single delta vs r1: u6 had tests: [] (orchestrator rejected). Now u6 ships test_cache_repo_layout.py. Other 5 units unchanged from r1 (Codex #3 YES).

Per-unit rationale (deltas from r1):

• u1~u5: unchanged; Codex #3 approved.
• u6: now ships tests/phase_z2_ai_fallback/test_cache_repo_layout.py — two invariants: (1) data/frame_cache/.gitkeep exists (repo layout); (2) IMP-17-CARVE-OUT.md contains persistent-backend marker substring (mirrors test_docs_sync.py pattern). estimate_lines 20→30.

Out of scope:

• AI body (IMP-33 c864fe0); fuzzy lookup (deferred); cache→catalog (R4); new router call sites; Stage 0 normalizer; prompts.py redesign beyond cardinality field exposure.

Rollback:

• Per-unit revert. cache.py shared (u2/u3/u5) → reverse order u5→u3→u2. u1/u6 additive. Generated JSON under data/frame_cache/ stays gitignored — delete working tree only.

Per-unit rationale:
u1 covers the no-hardcoding structural signature lock and removes sample/source_section_id leakage; tests must prove same 8 axes give same hash and any axis change changes it.
u2 covers the required cache path and cache value shape while preserving read-path determinism and cache-miss fallback for missing/corrupt files.
u3 covers contract/partial/catalog invalidation without making cache.py know how to compute project-specific hashes.
u4 covers the sole production Step 12 integration point and supplies the missing layout/cardinality/source-shape inputs before signature build.
u5 covers the issue write gate and auto-cache override while keeping the default flag off and visual_check_passed as a non-bypassable gate.
u6 covers the previously missing repo-layout/test gap: data/ is ignored today, data/frame_cache is absent, so .gitkeep needs an explicit exception plus a layout test.

Out-of-scope notes:
AI invocation logic, prompt redesign, cache-to-catalog promotion, new route_ai_fallback call sites, fuzzy lookup implementation, and Stage 0 mdx_normalizer integration remain out of scope.

Rollback strategy:
Revert the six unit filesets by unit if a unit regresses; cache files are content-addressed under data/frame_cache and can be removed without affecting AI hook behavior.

[Claude #1] Stage 3 code-edit IMP-46 — u1 signature builder

Executing unit: u1

■ unit_executed

• id: u1
• summary: Add signature.py with deterministic SHA256 over the 8 declared structural axes (frame_id, v4_label, cardinality, source_shape, h3_count, char_count_bucket, layout_preset, zone_position). Fixed char-count buckets 0-50 / 51-150 / 151-400 / 401-1000 / 1001+; source_shape enum (bullet/paragraph/table/mixed); SCHEMA_VERSION=1 embedded in hashed payload.

■ files_changed

• src/phase_z2_ai_fallback/signature.py (new, 76 SLOC)
• tests/phase_z2_ai_fallback/test_signature.py (new, 20 cases)
• tests/phase_z2_ai_fallback/test_ast_isolation.py (whitelist hashlib; stdlib peer of json/pathlib)

■ diff_summary

• New module src/phase_z2_ai_fallback/signature.py:
  • SCHEMA_VERSION = 1 constant, embedded inside the hashed JSON payload so a future schema bump auto-invalidates digests.
  • SourceShape(str, Enum) with members BULLET / PARAGRAPH / TABLE / MIXED.
  • CHAR_COUNT_BUCKET_LABELS = ("0-50", "51-150", "151-400", "401-1000", "1001+") exposed as a public tuple for cross-module reuse.
  • bucket_char_count(int) -> str: maps a non-negative int char count to one of the 5 fixed buckets; rejects bool, non-int, or negative input.
  • build_signature(*, frame_id, v4_label, cardinality, source_shape, h3_count, char_count_bucket, layout_preset, zone_position) -> str: keyword-only API restricted to the 8 declared axes. Coerces source_shape from str via SourceShape(...); validates char_count_bucket ∈ CHAR_COUNT_BUCKET_LABELS. Computes SHA256 over json.dumps(payload, sort_keys=True, ensure_ascii=False) → returns 64-char hex digest.
• New tests tests/phase_z2_ai_fallback/test_signature.py (20 cases, all pass):
  • schema_version == 1; bucket label tuple matches spec.
  • Determinism: same inputs → same digest, length 64.
  • Axis-change sensitivity: parametrized over all 8 axes — flipping any single axis mutates the digest.
  • source_shape string ⇔ enum equivalence.
  • Rejection of unknown source_shape and unknown char_count_bucket.
  • cardinality=None yields a valid digest distinct from cardinality=0.
  • Public-surface lock: inspect.signature(build_signature).parameters is exactly the 8-axis set (no template_id / source_section_ids / mdx_path leakage).
  • Bucket boundaries: exhaustively asserted at each edge (0, 50, 51, 150, 151, 400, 401, 1000, 1001, 10_000).
  • Type rejection on bucket_char_count(3.14) and bucket_char_count(True).
  • Stable-fixture lock: a known 8-tuple is rehashed inline to detect silent payload-shape drift.
• AST isolation guard (test_ast_isolation.py): added "hashlib" to _ALLOWED_TOP_LEVEL (alphabetical placement between enum and json). Stdlib peer of already-whitelisted json / pathlib / dataclasses. No forbidden surface widened — Phase Q / Kei / phase_z2_* runtime imports still rejected.

■ validation

• python -m pytest tests/phase_z2_ai_fallback/test_signature.py -q → 20 passed.
• python -m pytest tests/phase_z2_ai_fallback/ tests/test_family_contract_baseline.py -q → 136 passed (full fallback suite + baseline contract test green; AST isolation, schema, cache gate, step12, router, prompts, client mock all unaffected).

■ guardrails

• AI isolation contract: signature.py performs zero AI/network/MDX I/O. Pure stdlib (hashlib, json, enum).
• No-hardcoding lock: the 8-axis surface accepts no sample/section/template identifiers. The public-surface test enforces this structurally.
• Scope lock honored: u1 alone — no edits to cache.py, step12.py, pipeline, or config. Cache backend (u2), invalidation (u3), Step 12 wiring (u4), gate flag (u5), repo layout (u6) all untouched.
• Schema versioning: SCHEMA_VERSION is part of the hashed payload, so any future axis rename / addition can bump it for deterministic invalidation (will be the invariant that u3 fingerprints layer on top of, not replace).

■ remaining_units

• u2 — cache.py persistent JSON backend at data/frame_cache/{frame_id}/{signature_hash}.json
• u3 — fingerprint-based invalidation (contract_sha / partial_sha / catalog_sha)
• u4 — Step 12 helper contract extension + structural cache_key replacement
• u5 — --auto-cache CLI flag + settings.ai_fallback_auto_cache + 2^3 gate truth table
• u6 — .gitignore exception + data/frame_cache/.gitkeep + IMP-17-CARVE-OUT.md refresh + repo-layout test

■ follow_up_issue_candidates

• (none) — hashlib whitelist addition is in-scope u1 plumbing (stdlib parity with json); not a scope-creep axis. No other off-scope surface discovered.

stopping here per "1 turn = 1 step" rule; no commit, no push.

[Codex #1] Stage 3 code-edit review IMP-46 u1

Scope: verified only the single executed unit, u1.

Verdict: u1 is correct. The new signature builder is deterministic, content-addressed over only the 8 declared structural axes, embeds schema version 1 in the hashed payload, exposes the fixed char-count buckets, rejects invalid bucket/source-shape inputs, and does not include template, section, MDX, or sample identifiers in the signature surface. The AST whitelist update is limited to the stdlib hashlib import needed by this unit.

[Claude #2] Stage 3 code-edit IMP-46 — u2 persistent JSON cache backend

Executing unit: u2

■ unit_executed

• id: u2
• summary: Replace the IMP-33 u6 NotImplementedError marker in src/phase_z2_ai_fallback/cache.py with a content-addressed JSON backend at data/frame_cache/{frame_id}/{signature_hash}.json. Stored payload = {schema_version: 1, proposal, slide_css, fingerprints}. Missing / corrupt files → read_proposal returns None; mkdir(parents=True, exist_ok=True) on save. Both write gates (visual_check_passed AND user_approved) preserved BEFORE any filesystem touch.

■ files_changed

• src/phase_z2_ai_fallback/cache.py (rewrite, 137 SLOC — was 82 SLOC stub)
• tests/phase_z2_ai_fallback/test_cache.py (rewrite, ~290 SLOC — 31 test cases covering gates, round-trip, persistence layout, corruption tolerance)

■ diff_summary

• src/phase_z2_ai_fallback/cache.py
  • Module-level constants: SCHEMA_VERSION = 1, KEY_DELIMITER = "::", CACHE_ROOT: pathlib.Path = pathlib.Path("data/frame_cache") (mutable for monkeypatch-based test isolation; tests redirect to tmp_path).
  • AiFallbackCacheGateError(RuntimeError) — class preserved exactly (loud gate violation surface).
  • _parse_key(key) -> tuple[str, str] | None — splits "{frame_id}::{signature_hash}"; returns None if delimiter missing or component empty or extra :: present. Centralizes the on-disk layout decision in one place.
  • _cache_path(frame_id, signature_hash) -> pathlib.Path — single source of truth for the file layout (CACHE_ROOT / frame_id / f"{signature_hash}.json").
  • read_proposal(key):
    • Empty / non-string key → ValueError (loud; matches prior contract).
    • Legacy key (no ::) → silent None. This is router back-compat — test_router.py:58 still passes cache_key="frame:1171281190:cardinality:many" and must continue to miss safely until u4 replaces the cache_key at the step12 call site.
    • File missing → None. Corrupt JSON (OSError / json.JSONDecodeError) → None. Non-dict root, missing proposal key, non-dict proposal value, or AiFallbackProposal.model_validate failure (e.g. forbidden proposal_kind like mdx_text smuggled into a stale payload) → None. Read errors NEVER propagate — the cache is a hint, never a hard dependency.
  • save_proposal(key, proposal, *, visual_check_passed, user_approved, slide_css=None, fingerprints=None):
    • Gate order preserved: empty key → ValueError; wrong type → TypeError; visual_check_passed=False → AiFallbackCacheGateError; user_approved=False → AiFallbackCacheGateError. Both gates raise BEFORE the parent directory is touched (verified by test_save_gate_violation_does_not_touch_filesystem).
    • slide_css validated (str | None), fingerprints validated (dict | None), then key parsed via _parse_key; legacy key format → ValueError (loud — writes must use the structural form).
    • On success: path.parent.mkdir(parents=True, exist_ok=True), JSON payload written with sort_keys=True, ensure_ascii=False, indent=2. Returns the resolved pathlib.Path.
    • fingerprints is persisted but NOT compared in u2 — comparison / invalidation is u3's responsibility (explicit module docstring note).
  • Module docstring documents the on-disk layout, the legacy-key silent-miss back-compat, the u3 fingerprint deferral, and the AI-isolation invariant (no Anthropic / MDX / Phase Z runtime imports).
• tests/phase_z2_ai_fallback/test_cache.py — 31 cases. @pytest.fixture(autouse=True) _isolated_cache_root redirects cache_mod.CACHE_ROOT to tmp_path / "frame_cache" via monkeypatch.setattr for every test, so the production directory is never touched. Coverage:
  • read: missing file → None; empty key → ValueError; non-string key → ValueError; legacy key format → None (router back-compat); corrupt JSON → None; non-dict root → None; payload missing proposal → None; forbidden proposal_kind="mdx_text" → None (validator rejects).
  • write gates: visual_check=False rejects; user_approved=False rejects; both False rejects; gate violation does NOT create the frame_id directory; empty key → ValueError; non-proposal object → TypeError; legacy key format → ValueError; non-string slide_css → TypeError; non-dict fingerprints → TypeError; AiFallbackCacheGateError is not a NotImplementedError subclass.
  • persistence + round-trip: creates parent directories; returns resolved path; payload includes schema_version=1; payload includes proposal.model_dump(mode="json"); default slide_css=None and default fingerprints={}; round-trip with slide_css set; round-trip with fingerprints dict; read returns the same proposal after save; parametrized round-trip across all three ProposalKind values (BUILDER_OPTIONS_PATCH, PARTIAL_OVERRIDES, SLOT_MAPPING_PROPOSAL); overwrite an existing entry; file layout uses frame_id/ directory + signature_hash.json file; two distinct signature hashes under the same frame are isolated; triple-delimiter key rejected.
• No changes to tests/phase_z2_ai_fallback/test_ast_isolation.py — json and pathlib were already in the _ALLOWED_TOP_LEVEL whitelist, so the new backend introduces no new top-level imports.

■ validation

• python -m pytest tests/phase_z2_ai_fallback/test_cache.py tests/phase_z2_ai_fallback/test_ast_isolation.py -q → 55 passed in 0.26s.
• python -m pytest tests/phase_z2_ai_fallback/ -q → 156 passed in 0.27s (full AI fallback regression — includes test_router.py which still calls read_proposal("frame:1171281190:cardinality:many") and continues to get None because the legacy key format is now silently treated as a miss; PZ-1 unaffected).
• python -m pytest tests/test_family_contract_baseline.py -q → 4 passed in 0.59s.
• Public-surface introspection:
  • SCHEMA_VERSION == 1, KEY_DELIMITER == "::", CACHE_ROOT == pathlib.Path("data/frame_cache").
  • read_proposal(key: str) -> AiFallbackProposal | None.
  • save_proposal(key: str, proposal: AiFallbackProposal, *, visual_check_passed: bool, user_approved: bool, slide_css: str | None = None, fingerprints: dict | None = None) -> pathlib.Path.
  • AiFallbackCacheGateError MRO ends at RuntimeError (NOT a NotImplementedError — the IMP-33 marker is gone).

■ scope_locks_honoured

• u3 deferred: fingerprints field is persisted on save and the field is read back on disk, but read_proposal does NOT compare supplied fingerprints against the stored value. That mismatch-comparison logic is u3.
• u4 deferred: router.py, step12.py, and test_router.py are NOT modified. The router still calls read_proposal(cache_key) with the IMP-33 u7 legacy string. u2's parser silently misses on legacy keys so the router's cache path keeps returning None (the prior stub behavior). u4 will replace the cache_key at the step12 call site with the structural frame_id::signature_hash form.
• u5 deferred: --auto-cache CLI flag, settings.ai_fallback_auto_cache, and the auto_cache parameter on save_proposal are NOT introduced here. Both gates remain mandatory; neither can be bypassed in u2.
• u6 deferred: .gitignore exception for data/frame_cache/.gitkeep and the IMP-17-CARVE-OUT.md row refresh are NOT performed here.
• AI isolation contract preserved: no Anthropic, MDX, or Phase Z runtime imports; only stdlib (json, pathlib) + intra-package (schema).

■ remaining_units

• u3 (cache invalidation by fingerprints — read_proposal returns None on mismatch; new tests/phase_z2_ai_fallback/test_cache_invalidation.py).
• u4 (Step 12 helper inputs + structural cache_key replacement — src/phase_z2_ai_fallback/step12.py + tests/phase_z2_ai_fallback/test_step12.py).
• u5 (--auto-cache CLI flag + settings.ai_fallback_auto_cache + auto_cache kwarg on save_proposal + 2³ gate truth-table test).
• u6 (data/frame_cache/.gitkeep + .gitignore exception + IMP-17-CARVE-OUT.md cache row refresh + tests/phase_z2_ai_fallback/test_cache_repo_layout.py).

■ follow_up_issue_candidates

• (none — Stage 1 scope_lock holds; no axis discovered beyond the unit decomposition).

[Claude #2] Stage 3 code-edit IMP-46 — u2 persistent JSON cache backend Executing unit: u2 ■ unit_executed - id: u2 - summary: Replace the IMP-33 u6 `NotImplementedError` marker in `src/phase_z2_ai_fallback/cache.py` with a content-addressed JSON backend at `data/frame_cache/{frame_id}/{signature_hash}.json`. Stored payload = `{schema_version: 1, proposal, slide_css, fingerprints}`. Missing / corrupt files → `read_proposal` returns `None`; `mkdir(parents=True, exist_ok=True)` on save. Both write gates (`visual_check_passed` AND `user_approved`) preserved BEFORE any filesystem touch. ■ files_changed - src/phase_z2_ai_fallback/cache.py (rewrite, 137 SLOC — was 82 SLOC stub) - tests/phase_z2_ai_fallback/test_cache.py (rewrite, ~290 SLOC — 31 test cases covering gates, round-trip, persistence layout, corruption tolerance) ■ diff_summary - `src/phase_z2_ai_fallback/cache.py` - Module-level constants: `SCHEMA_VERSION = 1`, `KEY_DELIMITER = "::"`, `CACHE_ROOT: pathlib.Path = pathlib.Path("data/frame_cache")` (mutable for monkeypatch-based test isolation; tests redirect to `tmp_path`). - `AiFallbackCacheGateError(RuntimeError)` — class preserved exactly (loud gate violation surface). - `_parse_key(key) -> tuple[str, str] | None` — splits `"{frame_id}::{signature_hash}"`; returns `None` if delimiter missing or component empty or extra `::` present. Centralizes the on-disk layout decision in one place. - `_cache_path(frame_id, signature_hash) -> pathlib.Path` — single source of truth for the file layout (`CACHE_ROOT / frame_id / f"{signature_hash}.json"`). - `read_proposal(key)`: - Empty / non-string `key` → `ValueError` (loud; matches prior contract). - Legacy key (no `::`) → silent `None`. This is router back-compat — `test_router.py:58` still passes `cache_key="frame:1171281190:cardinality:many"` and must continue to miss safely until u4 replaces the cache_key at the step12 call site. - File missing → `None`. Corrupt JSON (`OSError` / `json.JSONDecodeError`) → `None`. Non-dict root, missing `proposal` key, non-dict `proposal` value, or `AiFallbackProposal.model_validate` failure (e.g. forbidden `proposal_kind` like `mdx_text` smuggled into a stale payload) → `None`. Read errors NEVER propagate — the cache is a hint, never a hard dependency. - `save_proposal(key, proposal, *, visual_check_passed, user_approved, slide_css=None, fingerprints=None)`: - Gate order preserved: empty key → `ValueError`; wrong type → `TypeError`; `visual_check_passed=False` → `AiFallbackCacheGateError`; `user_approved=False` → `AiFallbackCacheGateError`. Both gates raise BEFORE the parent directory is touched (verified by `test_save_gate_violation_does_not_touch_filesystem`). - `slide_css` validated (`str | None`), `fingerprints` validated (`dict | None`), then key parsed via `_parse_key`; legacy key format → `ValueError` (loud — writes must use the structural form). - On success: `path.parent.mkdir(parents=True, exist_ok=True)`, JSON payload written with `sort_keys=True, ensure_ascii=False, indent=2`. Returns the resolved `pathlib.Path`. - `fingerprints` is persisted but NOT compared in u2 — comparison / invalidation is u3's responsibility (explicit module docstring note). - Module docstring documents the on-disk layout, the legacy-key silent-miss back-compat, the u3 fingerprint deferral, and the AI-isolation invariant (no Anthropic / MDX / Phase Z runtime imports). - `tests/phase_z2_ai_fallback/test_cache.py` — 31 cases. `@pytest.fixture(autouse=True) _isolated_cache_root` redirects `cache_mod.CACHE_ROOT` to `tmp_path / "frame_cache"` via `monkeypatch.setattr` for every test, so the production directory is never touched. Coverage: - read: missing file → None; empty key → ValueError; non-string key → ValueError; legacy key format → None (router back-compat); corrupt JSON → None; non-dict root → None; payload missing `proposal` → None; forbidden `proposal_kind="mdx_text"` → None (validator rejects). - write gates: visual_check=False rejects; user_approved=False rejects; both False rejects; gate violation does NOT create the `frame_id` directory; empty key → ValueError; non-proposal object → TypeError; legacy key format → ValueError; non-string `slide_css` → TypeError; non-dict `fingerprints` → TypeError; `AiFallbackCacheGateError` is not a `NotImplementedError` subclass. - persistence + round-trip: creates parent directories; returns resolved path; payload includes `schema_version=1`; payload includes `proposal.model_dump(mode="json")`; default `slide_css=None` and default `fingerprints={}`; round-trip with `slide_css` set; round-trip with fingerprints dict; read returns the same proposal after save; **parametrized round-trip across all three `ProposalKind` values** (BUILDER_OPTIONS_PATCH, PARTIAL_OVERRIDES, SLOT_MAPPING_PROPOSAL); overwrite an existing entry; file layout uses `frame_id/` directory + `signature_hash.json` file; two distinct signature hashes under the same frame are isolated; triple-delimiter key rejected. - No changes to `tests/phase_z2_ai_fallback/test_ast_isolation.py` — `json` and `pathlib` were already in the `_ALLOWED_TOP_LEVEL` whitelist, so the new backend introduces no new top-level imports. ■ validation - `python -m pytest tests/phase_z2_ai_fallback/test_cache.py tests/phase_z2_ai_fallback/test_ast_isolation.py -q` → **55 passed in 0.26s**. - `python -m pytest tests/phase_z2_ai_fallback/ -q` → **156 passed in 0.27s** (full AI fallback regression — includes `test_router.py` which still calls `read_proposal("frame:1171281190:cardinality:many")` and continues to get `None` because the legacy key format is now silently treated as a miss; PZ-1 unaffected). - `python -m pytest tests/test_family_contract_baseline.py -q` → **4 passed in 0.59s**. - Public-surface introspection: - `SCHEMA_VERSION == 1`, `KEY_DELIMITER == "::"`, `CACHE_ROOT == pathlib.Path("data/frame_cache")`. - `read_proposal(key: str) -> AiFallbackProposal | None`. - `save_proposal(key: str, proposal: AiFallbackProposal, *, visual_check_passed: bool, user_approved: bool, slide_css: str | None = None, fingerprints: dict | None = None) -> pathlib.Path`. - `AiFallbackCacheGateError` MRO ends at `RuntimeError` (NOT a `NotImplementedError` — the IMP-33 marker is gone). ■ scope_locks_honoured - u3 deferred: `fingerprints` field is persisted on save and the field is read back on disk, but `read_proposal` does NOT compare supplied fingerprints against the stored value. That mismatch-comparison logic is u3. - u4 deferred: `router.py`, `step12.py`, and `test_router.py` are NOT modified. The router still calls `read_proposal(cache_key)` with the IMP-33 u7 legacy string. u2's parser silently misses on legacy keys so the router's cache path keeps returning `None` (the prior stub behavior). u4 will replace the cache_key at the step12 call site with the structural `frame_id::signature_hash` form. - u5 deferred: `--auto-cache` CLI flag, `settings.ai_fallback_auto_cache`, and the `auto_cache` parameter on `save_proposal` are NOT introduced here. Both gates remain mandatory; neither can be bypassed in u2. - u6 deferred: `.gitignore` exception for `data/frame_cache/.gitkeep` and the `IMP-17-CARVE-OUT.md` row refresh are NOT performed here. - AI isolation contract preserved: no Anthropic, MDX, or Phase Z runtime imports; only stdlib (`json`, `pathlib`) + intra-package (`schema`). ■ remaining_units - u3 (cache invalidation by fingerprints — `read_proposal` returns None on mismatch; new `tests/phase_z2_ai_fallback/test_cache_invalidation.py`). - u4 (Step 12 helper inputs + structural cache_key replacement — `src/phase_z2_ai_fallback/step12.py` + `tests/phase_z2_ai_fallback/test_step12.py`). - u5 (`--auto-cache` CLI flag + `settings.ai_fallback_auto_cache` + `auto_cache` kwarg on `save_proposal` + 2³ gate truth-table test). - u6 (`data/frame_cache/.gitkeep` + `.gitignore` exception + `IMP-17-CARVE-OUT.md` cache row refresh + `tests/phase_z2_ai_fallback/test_cache_repo_layout.py`). ■ follow_up_issue_candidates - (none — Stage 1 scope_lock holds; no axis discovered beyond the unit decomposition). ■ STOP - No commit, no push. The Gitea comment is the deliverable.

[Codex #2] Stage 3 code-edit review IMP-46 u2

Scope: verified only the single executed unit, u2.

Verdict: u2 is correct. The cache stub has been replaced with a persistent JSON backend at data/frame_cache/{frame_id}/{signature_hash}.json, stores schema_version, proposal, slide_css, and fingerprints, returns None for missing/corrupt/unparseable cached reads, preserves the dual write gate before filesystem writes, and keeps fingerprint comparison out of u2. No AI invocation path or save call site was added.

Minor wording note: the implementation returns the storage Path; it does not explicitly call Path.resolve() when CACHE_ROOT is relative. This does not violate the u2 contract.

[Claude #3] Stage 3 code-edit IMP-46 — u3 fingerprint invalidation

Executing unit: u3

■ unit_executed

• id: u3
• summary: Add fingerprint-based read-side invalidation to src/phase_z2_ai_fallback/cache.py. save_proposal already persisted the fingerprints dict verbatim (u2); u3 extends read_proposal with an optional fingerprints kwarg. When supplied, the stored fingerprints dict must equal the caller's dict by strict equality — any mismatch (single-axis drift, extra key, missing key, non-dict stored value, legacy entry with no fingerprints field) returns None. Default fingerprints=None performs no comparison (back-compat). Fingerprint computation stays outside cache.py: the module is a content-addressed comparator, not a hasher — preserves AI isolation and keeps the cache schema-agnostic.

■ files_changed

• src/phase_z2_ai_fallback/cache.py (modified, +47 / -10 — module docstring expanded with u3 contract; read_proposal gains keyword-only fingerprints: dict | None = None)
• tests/phase_z2_ai_fallback/test_cache_invalidation.py (new, 21 test cases, 305 SLOC)

■ diff_summary

• src/phase_z2_ai_fallback/cache.py
  • Module docstring header renamed u2 → u2 + u3; new section "u3 invalidation contract (this module is a comparator, not a computer)" documents:
    • save_proposal persists fingerprints verbatim — no fingerprint axis names are hardcoded in cache.py
    • read_proposal(fingerprints=...) enforces strict equality (NOT subset); default None skips comparison
    • Rationale for keeping computation outside: AI isolation + schema-agnostic (new fingerprint axes don't require editing cache.py)
  • read_proposal signature changed from (key: str) to (key: str, *, fingerprints: dict | None = None). The new kwarg is keyword-only so positional callers cannot accidentally pass an axis-extension dict.
  • New input validation: fingerprints is not None and not isinstance(fingerprints, dict) → TypeError (symmetric with save_proposal's fingerprints validation).
  • New comparison block placed AFTER file existence + JSON load + non-dict-root checks, but BEFORE the proposal validation: if fingerprints is not None and stored = data.get("fingerprints") is not a dict OR stored != fingerprints → return None. This ordering means missing-file / corrupt-JSON precedence is preserved (no false hit through a phantom equality check) and a hand-corrupted fingerprints field (e.g. serialized as a list) is treated as an invalidation, not as a TypeError.
  • No new module-level imports. No new constants. No fingerprint computation, hashing primitives, axis enumeration, or Phase Z runtime references introduced.
• tests/phase_z2_ai_fallback/test_cache_invalidation.py (new — 21 cases, all pass)
  • Save-side: test_save_persists_fingerprints_verbatim re-asserts the u2 round-trip foundation u3 depends on.
  • Back-compat (read without kwarg):
    • test_read_without_fingerprints_kwarg_returns_proposal — legacy callers still hit.
    • test_read_without_fingerprints_kwarg_ignores_stored_mismatch — entry saved with {"contract_sha": "old"} still readable by legacy reader.
  • Matching path:
    • test_read_with_matching_fingerprints_returns_proposal — exact dict equality hits.
    • test_read_with_empty_fingerprints_matches_empty_stored — both sides {} is a valid match, not a special-case None.
  • Invalidation (the 11-case core):
    • Parametrized over the three declared shas: test_read_invalidates_on_single_axis_drift[contract_sha|partial_sha|catalog_sha] — each axis individually breaks the match.
    • test_read_invalidates_when_caller_supplies_extra_key — strict equality (not subset) is the locked semantic.
    • test_read_invalidates_when_caller_supplies_subset — same, from the other direction.
    • test_read_invalidates_when_entry_saved_without_fingerprints — caller demands proof of freshness; empty stored set is not "compatible by default".
    • test_read_invalidates_when_stored_fingerprints_not_dict — hand-corrupted payload (fingerprints: [...]) misses cleanly.
    • test_read_invalidates_when_stored_fingerprints_field_missing — legacy payload (no fingerprints field at all) invalidates under fingerprint-aware lookup.
  • Precedence locks:
    • test_read_with_matching_fingerprints_still_loses_to_missing_file — file-missing wins.
    • test_read_with_matching_fingerprints_still_loses_to_corrupt_json — JSON-corrupt wins.
  • Input validation symmetry: test_read_rejects_non_dict_fingerprints[list|string|int] (3 cases) — TypeError matches save-side surface.
  • Module isolation lock: test_cache_module_has_no_fingerprint_computer — public surface of cache.py is grepped for hash/sha/fingerprint substrings; passes iff zero functions named for fingerprint computation exist. This is the structural defence against later patches accidentally pulling fingerprint computation into the cache module.
  • Cross-signature isolation: test_distinct_fingerprint_sets_isolated_per_signature — two entries with different sig_hashes hold their own fingerprints; crossed lookups miss, aligned lookups hit.

■ validation

• python -m pytest tests/phase_z2_ai_fallback/test_cache_invalidation.py tests/phase_z2_ai_fallback/test_cache.py tests/phase_z2_ai_fallback/test_ast_isolation.py tests/phase_z2_ai_fallback/test_router.py -q → 84 passed in 0.32s.
• python -m pytest tests/phase_z2_ai_fallback/ -q → 176 passed in 0.37s (whole package green, no regressions on u1 signature / u2 cache backend / IMP-33 router / AST guard).
• No src/** files touched outside src/phase_z2_ai_fallback/cache.py.
• AST isolation guard re-verified: no new top-level imports added; the existing hashlib whitelist from u1 is NOT used by cache.py (u3 does not import hashlib — comparison is plain dict equality, not hash recomputation).

■ guardrail / contract evidence

• AI isolation contract: cache.py still imports only json, pathlib, and src.phase_z2_ai_fallback.schema. No Anthropic, no MDX, no Phase Z runtime references.
• No-hardcoding: the three sha axis names (contract_sha / partial_sha / catalog_sha) do NOT appear in cache.py source — they are caller-supplied dict keys; cache.py only compares dicts. The names appear only in test fixtures and the module docstring (documentation).
• PZ-1 (normal-path AI=0): unchanged — read_proposal performs no AI invocation.
• Both write gates (visual_check_passed AND user_approved) preserved untouched. u3 only modifies the read path.
• Gate precedence preserved: u2's test_save_gate_violation_does_not_touch_filesystem and the 33-case u2 suite all still green.
• Strict equality (NOT subset) chosen explicitly to ensure invalidation on additive axis drift: if a future patch introduces a 4th fingerprint axis, every existing cache entry will invalidate on the next fingerprint-aware lookup until re-saved with the new axis. Subset semantics would silently honor stale entries — rejected.

■ remaining_units

• [u4, u5, u6]

■ follow_up_issue_candidates

• None. u3 is scope-locked to read-side comparator + tests; fingerprint computation (axis SHA derivation from live contract YAML / partial templates / catalog payloads) is u4's responsibility per Stage 2 plan and stays out of cache.py by design. No new axis discovered.

The names appear only in test fixtures and the module docstring (documentation). - PZ-1 (normal-path AI=0): unchanged — `read_proposal` performs no AI invocation. - Both write gates (`visual_check_passed` AND `user_approved`) preserved untouched. u3 only modifies the read path. - Gate precedence preserved: u2's `test_save_gate_violation_does_not_touch_filesystem` and the 33-case u2 suite all still green. - Strict equality (NOT subset) chosen explicitly to ensure invalidation on additive axis drift: if a future patch introduces a 4th fingerprint axis, every existing cache entry will invalidate on the next fingerprint-aware lookup until re-saved with the new axis. Subset semantics would silently honor stale entries — rejected. ■ remaining_units - [u4, u5, u6] ■ follow_up_issue_candidates - None. u3 is scope-locked to read-side comparator + tests; fingerprint computation (axis SHA derivation from live contract YAML / partial templates / catalog payloads) is u4's responsibility per Stage 2 plan and stays out of `cache.py` by design. No new axis discovered.

[Codex #3] Stage 3 code-edit review IMP-46 u3

Scope: verified only the single executed unit, u3.

Verdict: u3 is correct. read_proposal now accepts a keyword-only fingerprints comparator, strict equality invalidates mismatched cache entries, missing/corrupt/stale payloads still return None, and save_proposal continues to persist caller-supplied fingerprints without computing them inside cache.py. The cache module remains a storage/comparison layer and does not invoke AI or add Phase Z runtime coupling.

[Claude #4] Stage 3 code-edit IMP-46 — u4 structural cache key + fingerprints

Executing unit: u4

■ unit_executed

• id: u4
• summary: Replace the sample-identity cache_key (template_id::sorted(source_section_ids)) in src/phase_z2_ai_fallback/step12.py with a structural signature key "{frame_id}::{signature_hash}" derived from the 8 IMP-46 axes via build_signature (u1). Extend Step 12 helper inputs (unit attributes) for layout_preset, zone_position, source_shape, h3_count, char_count, and cardinality; project char_count through bucket_char_count (u1). Compute the three invalidation fingerprints (contract_sha, partial_sha, catalog_sha) and attach them — with the new cache_key — to each AI-eligible record for downstream save_proposal use. Exact-match lookup only (no fuzzy fallback added). v4_result.cardinality now mirrors the unit's cardinality (was hardcoded None).

■ files_changed

• src/phase_z2_ai_fallback/step12.py (modified, +82 / -2 — adds _sha256_of helper, catalog_sha_loader kwarg, structural signature + fingerprint block, record fields cache_key + fingerprints)
• tests/phase_z2_ai_fallback/test_step12.py (modified, +247 / -16 — replaces the legacy test_cache_key_includes_template_and_section_ids test with 14 new u4 cases; FakeUnit extended with 6 new signature-input fields)

■ diff_summary

• src/phase_z2_ai_fallback/step12.py

  • Module docstring expanded with an IMP-46 u4 — structural cache key + fingerprints section that names every signature axis read from unit attributes and explains why fingerprint computation lives here (cache.py is a comparator per u3 — keeps the cache module schema-agnostic).
  • New stdlib imports: hashlib, json (both already in the AST isolation whitelist — test_ast_isolation.py:39-42).
  • New intra-package import: bucket_char_count, build_signature from src.phase_z2_ai_fallback.signature (u1).
  • New module-level helper _sha256_of(payload: Any) -> str: deterministic SHA256 over json.dumps(payload, sort_keys=True, ensure_ascii=False). Used only for contract_sha and partial_sha.
  • gather_step12_ai_repair_proposals signature gains one new keyword-only argument:
    • catalog_sha_loader: Callable[[], str] | None = None — called once per gather invocation (verified by test_catalog_sha_loader_called_once_per_gather). When None, catalog_sha defaults to "" (sentinel — always present, so fingerprints is always a 3-key dict).
  • Record schema gains two fields, both initialised to None:
    • "cache_key": str | None — populated only on the AI-eligible code path; the structural axes are not guaranteed for skipped units, so the field is left None for not_provisional / design_reference_only_no_ai / route_not_ai_adaptation:* records.
    • "fingerprints": dict | None — same population rule.
  • Inside the AI-eligible branch (after route gates pass):
    • Read signature inputs from unit attributes via getattr with safe defaults (so existing test fixtures and pre-IMP-46 units survive): frame_id_value, cardinality, layout_preset (default ""), zone_position (default ""), source_shape (default "paragraph" — valid SourceShape enum member), h3_count (default 0), char_count (default 0).
    • char_count_bucket = bucket_char_count(char_count) — u1 fixed-bin projection.
    • signature_hash = build_signature(frame_id=..., v4_label=label or "", cardinality=..., source_shape=..., h3_count=..., char_count_bucket=..., layout_preset=..., zone_position=...) — 8-axis SHA256.
    • cache_key = f"{frame_id_value}::{signature_hash}" — matches cache.py _parse_key format (KEY_DELIMITER = "::"); validated by test_cache_key_is_compatible_with_cache_parse_key.
    • fingerprints = {"contract_sha": _sha256_of(frame_contract), "partial_sha": _sha256_of(figma_partial_json), "catalog_sha": catalog_sha}.
  • v4_result["cardinality"] now reads the unit's cardinality attribute instead of the hardcoded None from IMP-33 u8.
  • route_ai_fallback(cache_key=cache_key, ...) now receives the structural key (the router's existing read-side path is unchanged — read_proposal(cache_key) continues to perform exact-match lookup only, as required by the u4 contract).

• tests/phase_z2_ai_fallback/test_step12.py

  • Module docstring updated to declare the IMP-46 u4 coverage axis alongside the IMP-33 gates.
  • FakeUnit dataclass extended with 6 new fields (all with safe defaults): cardinality: int | None = None, layout_preset: str = "", zone_position: str = "", source_shape: str = "paragraph", h3_count: int = 0, char_count: int = 0. All pre-existing tests continue to construct FakeUnit(label=..., provisional=...) without modification.
  • New helper _ai_unit(**overrides): builds an AI-eligible (provisional=True, label="restructure") FakeUnit with realistic signature axes — keeps the u4 test bodies readable without mutating the existing test surface.
  • Legacy test_cache_key_includes_template_and_section_ids REMOVED — it asserted the broken template_id::sorted(section_ids) format that u4 explicitly replaces. Removing it (rather than xfailing) is consistent with the no-hardcoding lock: that key shape is now a defect, not a contract.
  • Existing test_record_shape_contract_is_stable renamed to test_record_shape_contract_is_stable_with_u4_fields and updated to assert exactly 12 keys (the original 10 + cache_key + fingerprints).
  • 14 new u4 cases:
    • test_cache_key_format_is_frame_id_plus_sha256 — cache_key.startswith("fid_123::"), suffix is 64-char lowercase hex; asserts the legacy substrings "tmpl_x" and "02-1" are absent.
    • test_cache_key_invariant_to_section_id_changes — source_section_ids=["02-1"] and ["05-2","07-3"] produce the same cache_key (no sample leakage).
    • test_cache_key_invariant_to_template_id_changes — frame_template_id is NOT in the signature surface (only frame_id is).
    • test_cache_key_changes_when_any_signature_axis_changes — parametrised-style loop over {frame_id, layout_preset, zone_position, source_shape, h3_count, char_count, cardinality}; each single-axis flip mutates cache_key. char_count=500 is chosen specifically to cross the 151-400 → 401-1000 bucket boundary (verifies bucketing, not raw count).
    • test_char_count_bucket_collapses_within_bucket — char_count=160 and char_count=399 both fall in "151-400" and produce identical keys; char_count=401 differs.
    • test_fingerprints_attached_to_ai_record — fingerprints dict has exactly the 3 declared keys, all string values; contract_sha and partial_sha match an inline recomputation of hashlib.sha256(json.dumps(..., sort_keys=True, ensure_ascii=False).encode()). Stable-fixture lock against silent fingerprint-format drift.
    • test_fingerprints_default_catalog_sha_is_empty_string — no catalog_sha_loader → catalog_sha == "" AND the key still appears in the dict (3-key invariant).
    • test_fingerprints_change_when_contract_changes — frame_contract={"a":1} vs {"a":2} mutates contract_sha, leaves partial_sha unchanged.
    • test_fingerprints_change_when_partial_changes — symmetric for figma_partial_json.
    • test_v4_result_cardinality_uses_unit_value — unit cardinality=7 flows into v4_result["cardinality"]=7; cardinality=None stays None. Closes the IMP-33 u8 hardcoded-None gap noted in Stage 1.
    • test_skipped_records_have_no_cache_key_or_fingerprints — not_provisional, reject, and light_edit paths all keep cache_key=None and fingerprints=None.
    • test_catalog_sha_loader_called_once_per_gather — MagicMock loader is called exactly once across 3 AI-eligible units (not once per unit).
    • test_record_shape_contract_is_stable_with_u4_fields — record key set is exactly {unit_index, source_section_ids, frame_template_id, label, route_hint, provisional, ai_called, skip_reason, proposal, error, cache_key, fingerprints}.
    • test_cache_key_is_compatible_with_cache_parse_key — round-trips the produced cache_key through cache._parse_key; asserts frame_id == "fid_123", len(signature_hash) == 64, no extra KEY_DELIMITER. Cross-module structural lock — the u4 producer and the u2 consumer agree on the key shape.

■ validation

• python -m pytest tests/phase_z2_ai_fallback/test_step12.py tests/phase_z2_ai_fallback/test_ast_isolation.py tests/phase_z2_ai_fallback/test_cache.py tests/phase_z2_ai_fallback/test_cache_invalidation.py tests/phase_z2_ai_fallback/test_router.py tests/phase_z2_ai_fallback/test_signature.py -q → 125 passed in 0.32s.
• python -m pytest tests/test_family_contract_baseline.py tests/phase_z2_ai_fallback/ -q → 192 passed in 1.02s (Stage 2 baseline regression suite green pre- and post-u4).
• git diff --stat → step12.py +84/-2, test_step12.py +247/-16 (315 insertions, 16 deletions, 2 files).
• Grep audit of src/phase_z2_ai_fallback/step12.py for source_section_ids|template_id|mdx_path|section_id|MDX 0[345]: every hit is either the docstring describing the LEGACY format, the record-schema docstring, the record initialisation (telemetry — never fed to build_signature), or the template_id variable that is used only as a key for the existing get_contract_fn / frame_visual_loader / figma_partial_loader callbacks. template_id and source_section_ids do NOT appear in build_signature(...) arguments or in the cache_key f-string. No-hardcoding lock honored.
• AI isolation contract: no new module imports outside the existing whitelist; hashlib and json were already allowed by test_ast_isolation.py:39-42. No Anthropic/MDX/Phase Q/Phase Z2 runtime imports added.

■ remaining_units

• [u5, u6]

■ scope_lock observations (NOT acted on)

• Router-side read fingerprint validation: the router's existing call is read_proposal(cache_key) — it does NOT yet pass the new fingerprints dict to read_proposal (the u3 invalidation comparator is therefore inert through the router today). u4's files list (per Stage 2 plan) is step12.py + test_step12.py only; router.py is out of scope. Step 12 produces and exposes the fingerprints; wiring them into the router's read call is a follow-up axis. Recording below.

■ follow_up_issue_candidates

• router read-side fingerprint validation — src/phase_z2_ai_fallback/router.py:66 calls read_proposal(cache_key) without fingerprints=. To complete the u3 invalidation chain end-to-end (so a stale cache entry with changed contract_sha / partial_sha / catalog_sha misses through the router), the router needs to accept a fingerprints kwarg from gather_step12_ai_repair_proposals and forward it to read_proposal. This is not required by the Stage 2 plan's u4 scope, but the cache-invalidation behaviour is incomplete without it. Suggest filing as a small follow-up issue (or folding into u5 if the orchestrator consents — but strictly outside the unit list as written).
• catalog_sha source-of-truth — catalog_sha_loader is a Callable[[], str]. The actual catalog content (Step 2 plan says the invalidation trigger is templates/phase_z2/catalog/frame_contracts.yaml) is not yet wired here — only the loader hook exists. Production wiring of a real catalog sha calculator at the pipeline integration site is a separate task.

DO NOT commit or push (Stage 3 unit policy).

[Claude #4] Stage 3 code-edit IMP-46 — u4 structural cache key + fingerprints Executing unit: u4 ■ unit_executed - id: u4 - summary: Replace the sample-identity cache_key (`template_id::sorted(source_section_ids)`) in `src/phase_z2_ai_fallback/step12.py` with a structural signature key `"{frame_id}::{signature_hash}"` derived from the 8 IMP-46 axes via `build_signature` (u1). Extend Step 12 helper inputs (unit attributes) for `layout_preset`, `zone_position`, `source_shape`, `h3_count`, `char_count`, and `cardinality`; project `char_count` through `bucket_char_count` (u1). Compute the three invalidation fingerprints (`contract_sha`, `partial_sha`, `catalog_sha`) and attach them — with the new `cache_key` — to each AI-eligible record for downstream `save_proposal` use. Exact-match lookup only (no fuzzy fallback added). v4_result.cardinality now mirrors the unit's cardinality (was hardcoded `None`). ■ files_changed - src/phase_z2_ai_fallback/step12.py (modified, +82 / -2 — adds `_sha256_of` helper, `catalog_sha_loader` kwarg, structural signature + fingerprint block, record fields `cache_key` + `fingerprints`) - tests/phase_z2_ai_fallback/test_step12.py (modified, +247 / -16 — replaces the legacy `test_cache_key_includes_template_and_section_ids` test with 14 new u4 cases; FakeUnit extended with 6 new signature-input fields) ■ diff_summary - `src/phase_z2_ai_fallback/step12.py` - Module docstring expanded with an `IMP-46 u4 — structural cache key + fingerprints` section that names every signature axis read from unit attributes and explains why fingerprint *computation* lives here (cache.py is a comparator per u3 — keeps the cache module schema-agnostic). - New stdlib imports: `hashlib`, `json` (both already in the AST isolation whitelist — `test_ast_isolation.py:39-42`). - New intra-package import: `bucket_char_count`, `build_signature` from `src.phase_z2_ai_fallback.signature` (u1). - New module-level helper `_sha256_of(payload: Any) -> str`: deterministic SHA256 over `json.dumps(payload, sort_keys=True, ensure_ascii=False)`.

Closes the IMP-33 u8 hardcoded-`None` gap noted in Stage 1. - `test_skipped_records_have_no_cache_key_or_fingerprints` — `not_provisional`, `reject`, and `light_edit` paths all keep `cache_key=None` and `fingerprints=None`. - `test_catalog_sha_loader_called_once_per_gather` — `MagicMock` loader is called exactly once across 3 AI-eligible units (not once per unit). - `test_record_shape_contract_is_stable_with_u4_fields` — record key set is exactly `{unit_index, source_section_ids, frame_template_id, label, route_hint, provisional, ai_called, skip_reason, proposal, error, cache_key, fingerprints}`. - `test_cache_key_is_compatible_with_cache_parse_key` — round-trips the produced `cache_key` through `cache._parse_key`; asserts `frame_id == "fid_123"`, `len(signature_hash) == 64`, no extra `KEY_DELIMITER`. Cross-module structural lock — the u4 producer and the u2 consumer agree on the key shape. ■ validation - `python -m pytest tests/phase_z2_ai_fallback/test_step12.py tests/phase_z2_ai_fallback/test_ast_isolation.py tests/phase_z2_ai_fallback/test_cache.py tests/phase_z2_ai_fallback/test_cache_invalidation.py tests/phase_z2_ai_fallback/test_router.py tests/phase_z2_ai_fallback/test_signature.py -q` → **125 passed in 0.32s**. - `python -m pytest tests/test_family_contract_baseline.py tests/phase_z2_ai_fallback/ -q` → **192 passed in 1.02s** (Stage 2 baseline regression suite green pre- and post-u4). - `git diff --stat` → `step12.py +84/-2`, `test_step12.py +247/-16` (315 insertions, 16 deletions, 2 files). - `Grep` audit of `src/phase_z2_ai_fallback/step12.py` for `source_section_ids|template_id|mdx_path|section_id|MDX 0[345]`: every hit is either the docstring describing the LEGACY format, the record-schema docstring, the record initialisation (telemetry — never fed to `build_signature`), or the `template_id` variable that is used **only** as a key for the existing `get_contract_fn` / `frame_visual_loader` / `figma_partial_loader` callbacks. **`template_id` and `source_section_ids` do NOT appear in `build_signature(...)` arguments or in the `cache_key` f-string.** No-hardcoding lock honored. - AI isolation contract: no new module imports outside the existing whitelist; `hashlib` and `json` were already allowed by `test_ast_isolation.py:39-42`. No Anthropic/MDX/Phase Q/Phase Z2 runtime imports added. ■ remaining_units - [u5, u6] ■ scope_lock observations (NOT acted on) - Router-side read fingerprint validation: the router's existing call is `read_proposal(cache_key)` — it does NOT yet pass the new `fingerprints` dict to `read_proposal` (the u3 invalidation comparator is therefore inert through the router today). u4's files list (per Stage 2 plan) is `step12.py + test_step12.py` only; `router.py` is out of scope. Step 12 produces and exposes the fingerprints; wiring them into the router's read call is a follow-up axis. Recording below. ■ follow_up_issue_candidates - **router read-side fingerprint validation** — `src/phase_z2_ai_fallback/router.py:66` calls `read_proposal(cache_key)` without `fingerprints=`. To complete the u3 invalidation chain end-to-end (so a stale cache entry with changed `contract_sha` / `partial_sha` / `catalog_sha` misses through the router), the router needs to accept a `fingerprints` kwarg from `gather_step12_ai_repair_proposals` and forward it to `read_proposal`. This is **not** required by the Stage 2 plan's u4 scope, but the cache-invalidation behaviour is incomplete without it. Suggest filing as a small follow-up issue (or folding into u5 if the orchestrator consents — but strictly outside the unit list as written). - **catalog_sha source-of-truth** — `catalog_sha_loader` is a `Callable[[], str]`. The actual catalog content (Step 2 plan says the invalidation trigger is `templates/phase_z2/catalog/frame_contracts.yaml`) is not yet wired here — only the loader hook exists. Production wiring of a real catalog sha calculator at the pipeline integration site is a separate task. DO NOT commit or push (Stage 3 unit policy).

[Codex #4] Stage 3 code-edit review IMP-46 u4

Scope: verified only the single executed unit, u4.

Verdict: u4 is correct. Step 12 now builds cache keys as {frame_id}::{signature_hash} using the u1 structural signature helper, derives the char-count bucket before hashing, forwards unit cardinality into v4_result, computes the three invalidation fingerprints outside cache.py, and attaches cache_key plus fingerprints only for AI-eligible records. The legacy template/section-id cache key is gone from the router call path, fuzzy lookup was not added, and the change does not introduce AI invocation outside the existing Step 12 router call.

[Claude #5] Stage 3 code-edit IMP-46 — u5 auto-cache CLI flag + 2^3 gate truth table

Executing unit: u5

■ unit_executed

• id: u5
• summary: Wire IMP-46 u5 auto-cache opt-in across three layers — (1) add ai_fallback_auto_cache: bool = False to src/config.py Settings; (2) extend src/phase_z2_ai_fallback/cache.py::save_proposal with a keyword-only auto_cache: bool = False parameter that bypasses ONLY the user_approved gate (visual_check_passed remains mandatory and non-bypassable); (3) add --auto-cache CLI flag in src/phase_z2_pipeline.py that mutates settings.ai_fallback_auto_cache=True at parse time. The 2^3 gate truth table over (visual_check_passed, user_approved, auto_cache) is now exhaustively enumerated in tests/phase_z2_ai_fallback/test_cache.py with exactly three persisting rows: (T,T,F), (T,T,T), (T,F,T). Every other row raises AiFallbackCacheGateError before any filesystem touch.

■ files_changed

• src/config.py (+8 lines — ai_fallback_auto_cache: bool = False Settings field + docstring)
• src/phase_z2_ai_fallback/cache.py (+~30/-10 lines — save_proposal(auto_cache=False) keyword-only param, docstring expanded with u5 contract section, module docstring u2 + u3 → u2 + u3 + u5)
• src/phase_z2_pipeline.py (+~20 lines — --auto-cache argparse flag + in-process settings.ai_fallback_auto_cache=True mutation)
• tests/phase_z2_ai_fallback/test_cache.py (+~110 lines — 8-row parametrised truth-table test + 5 targeted u5 cases)
• tests/test_phase_z2_ai_fallback_config.py (+~12 lines — test_ai_fallback_auto_cache_default_off)

■ diff_summary

• src/config.py
  • New field ai_fallback_auto_cache: bool = False placed alongside the existing IMP-33 u1 ai_fallback_* block. Docstring explains the gate semantics ("bypasses user_approved only; visual_check_passed never bypassable") and locks the default OFF + CLI mutation contract.
• src/phase_z2_ai_fallback/cache.py
  • Module docstring header: IMP-46 u2 + u3 → IMP-46 u2 + u3 + u5. New "u5 auto-cache contract" section enumerates the truth table (3 cells succeed, 5 raise) and pins the keyword-only / default-False shape.
  • Guardrails block updated: "Both write gates preserved — visual_check_passed=False always raises … user_approved=False also raises by default; the IMP-46 u5 auto_cache=True override bypasses ONLY the user_approved gate (visual_check_passed is never bypassed). Gate violation never silently no-ops."
  • save_proposal signature gains keyword-only auto_cache: bool = False at the end of the kwargs block (after fingerprints). Position-only callers cannot accidentally pass it.
  • New type-check: if not isinstance(auto_cache, bool): raise TypeError("auto_cache must be a bool"). Symmetric with slide_css / fingerprints validation.
  • Gate logic change — single line:
    • Before: if not user_approved: raise AiFallbackCacheGateError(...)
    • After: if not user_approved and not auto_cache: raise AiFallbackCacheGateError(...)
  • The visual_check_passed gate is unchanged — auto_cache does NOT appear in that branch. Error messages updated to reflect the new bypass surface ("auto_cache cannot bypass this gate" on visual-check failure; "Pass auto_cache=True (or --auto-cache on the CLI) to bypass" on user-approved failure).
  • No new imports. No src.config import inside cache.py — the cache module remains a pure comparator/storage layer that takes the resolved boolean from the caller (preserves AI isolation contract tests/phase_z2_ai_fallback/test_ast_isolation.py:48-69).
• src/phase_z2_pipeline.py
  • New --auto-cache flag added to the existing if __name__ == "__main__" argparse block (after --override-section-assignment, before args = parser.parse_args()). action="store_true", default=False. Help text states the gate semantics + setting wiring.
  • After parse_args(): a 3-line conditional imports settings from src.config and sets ai_fallback_auto_cache=True when the flag is present. The deferred import (inside if args.auto_cache:) keeps src.config off the unconditional pipeline import surface — only operators who opt in pull it in.
  • The mutation is in-process only — no .env write, no side effects between runs. A subsequent pipeline run without --auto-cache starts back at the Settings default (False).
• tests/phase_z2_ai_fallback/test_cache.py
  • New section header "IMP-46 u5: auto_cache gate (2^3 truth table)".
  • _GATE_TRUTH_TABLE constant — 8 rows, exhaustive Cartesian product of (V, U, A) × expect_persist. Hand-locked, NOT generated from the implementation, so a regression in the gate logic surfaces as a row failure (3 persist + 5 raise).
  • test_save_gate_truth_table parametrised — for each row, either calls save_proposal and asserts the file exists (persist row), or asserts AiFallbackCacheGateError raises AND the frame_id directory is absent (gate row — symmetric with the existing test_save_gate_violation_does_not_touch_filesystem).
  • test_auto_cache_default_off_preserves_dual_gate_semantics — calling without the auto_cache kwarg keeps the IMP-46 u2 behaviour (user_approved=False raises with "user_approved" in the message; no directory created).
  • test_auto_cache_cannot_bypass_visual_check — (V=False, U=True, A=True) row promoted to its own assertion that also checks the error message mentions visual_check_passed (regression sentinel against accidentally moving auto_cache into the visual-check branch).
  • test_auto_cache_bypass_user_approved_persists — (V=True, U=False, A=True) round-trip: persists, file exists, read_proposal returns the original payload.
  • test_auto_cache_rejects_non_bool — passing auto_cache="yes" raises TypeError (symmetric with the existing non-string / non-dict guards for slide_css and fingerprints).
  • test_auto_cache_is_keyword_only — inspect.signature(save_proposal).parameters["auto_cache"] is KEYWORD_ONLY and default False. Locks the public surface so a future refactor can't accidentally make it positional or default-True.
• tests/test_phase_z2_ai_fallback_config.py
  • New section explaining the u5 CLI / settings contract.
  • test_ai_fallback_auto_cache_default_off — Settings().ai_fallback_auto_cache is False. The CLI flag mutates the in-process settings instance; the default must stay OFF so the dual-gate contract survives without an operator opt-in.

■ validation

• python -m pytest tests/phase_z2_ai_fallback/test_cache.py tests/test_phase_z2_ai_fallback_config.py -q → 51 passed in 0.22s
• python -m pytest tests/phase_z2_ai_fallback/ -q → 201 passed in 0.40s (u1-u4 regression incl. test_ast_isolation, test_signature, test_cache_invalidation, test_step12 all green)
• python -m pytest tests/test_family_contract_baseline.py -q → 4 passed in 0.59s
• python -m src.phase_z2_pipeline --help → --auto-cache flag surfaced with the documented help text
• AST isolation guard re-confirmed: cache.py imports unchanged (json, pathlib, src.phase_z2_ai_fallback.schema); no src.config import inside src/phase_z2_ai_fallback/ (the setting is read by the CLI entry point and the resolved bool is passed in by callers, preserving the AI-isolation contract tests/phase_z2_ai_fallback/test_ast_isolation.py:48-69)

■ scope-lock verification

• ✅ u5 declared files only (config.py / cache.py / phase_z2_pipeline.py / test_cache.py / test_phase_z2_ai_fallback_config.py).
• ✅ No route_ai_fallback call site changes — IMP-33 AI hook untouched.
• ✅ No read_proposal signature change — u3 fingerprint comparator surface preserved.
• ✅ No save_proposal call site changes outside tests — there is no production save_proposal invocation yet (verified by rg "save_proposal\\(" src — only cache.py definition + docstring references in router.py).
• ✅ visual_check_passed gate is non-bypassable — auto_cache only relaxes user_approved. Truth-table row (V=False, U=True, A=True) raises, locked by test_auto_cache_cannot_bypass_visual_check.
• ✅ Settings default OFF — Settings().ai_fallback_auto_cache is False (test_ai_fallback_auto_cache_default_off). Honours feedback_ai_isolation_contract (auto-cache is an explicit operator opt-in, not silent).
• ✅ No-hardcoding lock — no sample / MDX / template_id specific literal added. auto_cache is a pure axis of the cache write gate.

■ remaining_units

• [u6] — Track data/frame_cache/.gitkeep via .gitignore exception under the existing data/ ignore, add repo-layout coverage (tests/phase_z2_ai_fallback/test_cache_repo_layout.py), and refresh docs/architecture/IMP-17-CARVE-OUT.md cache row from stub status → persistent backend status.

■ follow_up_issue_candidates

• None. u5 scope-lock held; no axis discovered outside (V, U, A) × cache write surface.

FINAL_CONSENSUS_TARGET: continue_same (u6 remains)

The CLI flag mutates the in-process settings instance; the default must stay OFF so the dual-gate contract survives without an operator opt-in. ■ validation - `python -m pytest tests/phase_z2_ai_fallback/test_cache.py tests/test_phase_z2_ai_fallback_config.py -q` → 51 passed in 0.22s - `python -m pytest tests/phase_z2_ai_fallback/ -q` → 201 passed in 0.40s (u1-u4 regression incl. test_ast_isolation, test_signature, test_cache_invalidation, test_step12 all green) - `python -m pytest tests/test_family_contract_baseline.py -q` → 4 passed in 0.59s - `python -m src.phase_z2_pipeline --help` → `--auto-cache` flag surfaced with the documented help text - AST isolation guard re-confirmed: cache.py imports unchanged (`json`, `pathlib`, `src.phase_z2_ai_fallback.schema`); no `src.config` import inside `src/phase_z2_ai_fallback/` (the setting is read by the CLI entry point and the resolved bool is passed in by callers, preserving the AI-isolation contract `tests/phase_z2_ai_fallback/test_ast_isolation.py:48-69`) ■ scope-lock verification - ✅ u5 declared files only (config.py / cache.py / phase_z2_pipeline.py / test_cache.py / test_phase_z2_ai_fallback_config.py). - ✅ No `route_ai_fallback` call site changes — IMP-33 AI hook untouched. - ✅ No `read_proposal` signature change — u3 fingerprint comparator surface preserved. - ✅ No `save_proposal` call site changes outside tests — there is no production `save_proposal` invocation yet (verified by `rg "save_proposal\\(" src` — only `cache.py` definition + docstring references in `router.py`). - ✅ `visual_check_passed` gate is non-bypassable — `auto_cache` only relaxes `user_approved`. Truth-table row `(V=False, U=True, A=True)` raises, locked by `test_auto_cache_cannot_bypass_visual_check`. - ✅ Settings default OFF — `Settings().ai_fallback_auto_cache is False` (`test_ai_fallback_auto_cache_default_off`). Honours `feedback_ai_isolation_contract` (auto-cache is an explicit operator opt-in, not silent). - ✅ No-hardcoding lock — no sample / MDX / template_id specific literal added. `auto_cache` is a pure axis of the cache write gate. ■ remaining_units - [u6] — Track `data/frame_cache/.gitkeep` via `.gitignore` exception under the existing `data/` ignore, add repo-layout coverage (`tests/phase_z2_ai_fallback/test_cache_repo_layout.py`), and refresh `docs/architecture/IMP-17-CARVE-OUT.md` cache row from stub status → persistent backend status. ■ follow_up_issue_candidates - None. u5 scope-lock held; no axis discovered outside `(V, U, A)` × cache write surface. FINAL_CONSENSUS_TARGET: continue_same (u6 remains)

[Codex #5] Stage 3 code-edit review IMP-46 u5

Scope: verified only the single executed unit, u5.

Verdict: u5 is correct. Settings.ai_fallback_auto_cache defaults to False, save_proposal now accepts a keyword-only auto_cache: bool = False, and the gate logic preserves visual_check_passed as non-bypassable while allowing auto_cache=True to bypass only user_approved=False. The CLI adds --auto-cache as a store_true flag and mutates settings.ai_fallback_auto_cache=True after argument parsing. I did not find an added AI invocation or cache-module dependency on Phase Z runtime settings.

[Claude #1] Stage 1 problem-review — IMP-46 (#62) residual scope after #76 absorption

Carve-out status (#76 absorption)

Commit 1186ad8 (#76 IMP-47B activation) absorbed substantially all of the originally-planned IMP-46 implementation_units. Per memory rule project_imp46_carveout_caveat, Stage 1 must enumerate what is already merged and bound new work to NON-overlapping territory only.

Already merged in 1186ad8 (DO NOT re-stir):

Unit	Scope	Lands in
u1	8-axis structural signature (build_signature, bucket_char_count)	src/phase_z2_ai_fallback/signature.py:1-92
u2	Persistent JSON backend at data/frame_cache/{frame_id}/{signature_hash}.json	src/phase_z2_ai_fallback/cache.py:108-243
u3	Fingerprints invalidation (strict-equality over contract_sha / partial_sha / catalog_sha)	src/phase_z2_ai_fallback/cache.py:38-44, 145-148
u4 (compute side)	Step 12 builds structural cache_key + fingerprints from unit attributes	src/phase_z2_ai_fallback/step12.py:160-185
u5	--auto-cache CLI + settings.ai_fallback_auto_cache (bypasses ONLY user_approved)	src/config.py:29, src/phase_z2_pipeline.py:6025-6037, src/phase_z2_ai_fallback/cache.py:158-217
u6	data/frame_cache/.gitkeep + .gitignore payload exclusion + carve-out doc	data/frame_cache/.gitkeep, .gitignore, docs/architecture/IMP-17-CARVE-OUT.md:54
save-side wiring	_persist_ai_repair_proposals_to_cache called after Step 14 visual check, threading visual_check_passed from overflow result and auto_cache from settings	src/phase_z2_pipeline.py:718-775, 5534-5550

Residual root cause (1 axis)

Axis R — Router read-path fingerprint enforcement gap.

• route_ai_fallback(cache_key, ...) accepts no fingerprints parameter (src/phase_z2_ai_fallback/router.py:43-53).
• Inside the router, cached = read_proposal(cache_key) is called WITHOUT fingerprints=... (src/phase_z2_ai_fallback/router.py:66).
• Step 12 already computes the three fingerprints (contract_sha / partial_sha / catalog_sha) and stores them in the per-unit record (src/phase_z2_ai_fallback/step12.py:179-185), but never threads them through to the router.
• Self-acknowledged TODO at src/phase_z2_ai_fallback/step12.py:48-51: "the router's existing read_proposal(cache_key) continues to perform exact-match lookup only (fuzzy is deferred per Stage 2 plan); read-side fingerprint validation through the router is a follow-up axis."

Consequence: When a frame contract / partial template / catalog payload changes, the save-side correctly tags new entries with fresh fingerprints, but lookups continue to return stale entries because the read path does not compare fingerprints. The invalidation contract documented in cache.py:28-44 is enforceable only at the caller of read_proposal, and the production caller (router) does not pass fingerprints. Issue body explicit guardrail "contract/partial 변경 시 invalidate (cache 일관성)" therefore is half-enforced: tested in unit isolation, not enforced in production read path.

Out of scope (explicit exclusions, carve-out boundary)

• Re-stirring cache.py, signature.py, save-side pipeline wiring, --auto-cache semantics, .gitignore, or data/frame_cache/.gitkeep (all merged in 1186ad8 — see carve-out table).
• AI call itself / prompt redesign (IMP-33 closed at c864fe0).
• New route_ai_fallback call sites beyond current production site src/phase_z2_ai_fallback/step12.py:194-203.
• Fuzzy match secondary tier (issue marks "옵션" — deferred per Stage 2 plan).
• Cache → catalog promotion (R4 wave).
• mdx_normalizer Stage 0 integration (separate lock 2026-05-08).
• user_approved UX gate (documented design choice — pipeline relies on auto_cache opt-in per IMP-46 u5; see src/phase_z2_pipeline.py:5538-5542).
• Step 17 cache integration (Step 17 entry is structurally blocked behind IMP-34/35 prerequisites per IMP-17-CARVE-OUT.md:52).

Proposed scope-lock (residual axis only)

• Extend route_ai_fallback signature with an optional fingerprints: dict | None = None keyword-only kwarg. Default None preserves current router behavior and back-compat with existing test_router.py cases.
• Pass fingerprints through to read_proposal(cache_key, fingerprints=fingerprints) (cache.py:108 already supports this kwarg; no cache.py edit needed).
• Thread fingerprints from src/phase_z2_ai_fallback/step12.py:194-203 route_ai_fallback(...) call. Source = the existing fingerprints dict already computed at step12.py:179-185. No new computation — pure reuse.
• Update tests/phase_z2_ai_fallback/test_router.py with three new cases:
  1. cache-hit with matching fingerprints → returns cached (validates short-circuit preserved)
  2. cache-hit with mismatched fingerprints → read_proposal returns None → falls through to client path (validates strict-equality invalidation reaches production)
  3. cache-hit with fingerprints=None (legacy back-compat) → returns cached without comparison (preserves existing router test surface)
• Update tests/phase_z2_ai_fallback/test_step12.py to assert fingerprints is forwarded to route_ai_fallback (mock router, inspect kwargs).
• No new modules, no new files. Touched files: src/phase_z2_ai_fallback/router.py (signature + one call), src/phase_z2_ai_fallback/step12.py (one call site), tests/phase_z2_ai_fallback/test_router.py (3 cases), tests/phase_z2_ai_fallback/test_step12.py (1-2 assertions).

Guardrails (Stage 2 binding)

• carve-out caveat (project_imp46_carveout_caveat): files modified in 1186ad8 are NOT in scope for content rewrites. Only the call site in step12.py:194-203 (the route_ai_fallback(...) invocation) gets one kwarg added. No re-touch of the fingerprints computation block (step12.py:179-185).
• AI isolation (feedback_ai_isolation_contract): cache layer adds no AI call; router still does not import save_proposal; test_router_does_not_import_save_proposal (test_router.py:153) invariant holds. AST isolation test (tests/phase_z2_ai_fallback/test_ast_isolation.py) keeps the import whitelist intact.
• PZ-1 invariant: flag-off and route-mismatch short-circuits execute BEFORE fingerprint comparison (router lines 61-65 unchanged). AI=0 normal-path count remains 0.
• No hardcoding (feedback_no_hardcoding): fingerprints sourced exclusively from existing step12.py compute (frame_contract / figma_partial_json / catalog_sha_loader). No new per-sample literals; no MDX section ids re-enter the signature surface.
• Process-first: the gap is a missing thread, not a wrong value. Fix is "wire the kwarg," not "patch the symptom downstream."
• Artifact-status naming (feedback_artifact_status_naming): cache hit/miss must remain a distinct axis from rendered / visual_check / coverage. Step 12 record schema (step12.py:122-135) already keeps them separate — no merging.
• 1 turn = 1 step (feedback_one_step_per_turn): Stage 1 = problem-review comment only; no code edit, no plan unit enumeration. Stage 2 enumerates units.
• Scope-qualified verification (feedback_scope_qualified_verification): Stage 4 verify must scope to router-fingerprint axis only — no "all tests pass" generic claim.

Unresolved questions for Stage 2

• q1: should route_ai_fallback's fingerprints kwarg be strictly keyword-only (recommended for forward compat) or positional? Default recommendation: keyword-only, matching the cache.py pattern (read_proposal(key, *, fingerprints=None) at cache.py:108-112).
• q2: when fingerprints=None is passed AND a cache entry exists with stored non-empty fingerprints, current read_proposal behavior = return entry (no comparison). Stage 2 to confirm: keep legacy back-compat (router default None → no invalidation enforcement, opt-in via step12 thread) OR tighten to "fingerprints=None ⇒ never trust stored entry with fingerprints"? Default recommendation: keep legacy back-compat to honor cache.py:38-44 strict-equality semantics (caller opt-in to invalidation).
• q3: should the catalog_sha source be wired from step12.py:116-118 (current: optional catalog_sha_loader defaulting to "") up through the production pipeline call site, or is "" acceptable until B4 frame_selection evidence integration formalizes the catalog snapshot? Default recommendation: defer — "" is the same fingerprint on both write and read until catalog_sha_loader is wired upstream, so invalidation behaves consistently within a release; tighten in a follow-up axis when B4 lands.

[Claude #1] Stage 1 problem-review — IMP-46 (#62) residual scope after #76 absorption # Carve-out status (#76 absorption) Commit `1186ad8` (#76 IMP-47B activation) absorbed substantially all of the originally-planned IMP-46 implementation_units. Per memory rule `project_imp46_carveout_caveat`, Stage 1 must enumerate what is already merged and bound new work to NON-overlapping territory only. **Already merged in `1186ad8` (DO NOT re-stir):** | Unit | Scope | Lands in | |---|---|---| | u1 | 8-axis structural signature (`build_signature`, `bucket_char_count`) | `src/phase_z2_ai_fallback/signature.py:1-92` | | u2 | Persistent JSON backend at `data/frame_cache/{frame_id}/{signature_hash}.json` | `src/phase_z2_ai_fallback/cache.py:108-243` | | u3 | Fingerprints invalidation (strict-equality over `contract_sha` / `partial_sha` / `catalog_sha`) | `src/phase_z2_ai_fallback/cache.py:38-44, 145-148` | | u4 (compute side) | Step 12 builds structural cache_key + fingerprints from unit attributes | `src/phase_z2_ai_fallback/step12.py:160-185` | | u5 | `--auto-cache` CLI + `settings.ai_fallback_auto_cache` (bypasses ONLY `user_approved`) | `src/config.py:29`, `src/phase_z2_pipeline.py:6025-6037`, `src/phase_z2_ai_fallback/cache.py:158-217` | | u6 | `data/frame_cache/.gitkeep` + `.gitignore` payload exclusion + carve-out doc | `data/frame_cache/.gitkeep`, `.gitignore`, `docs/architecture/IMP-17-CARVE-OUT.md:54` | | save-side wiring | `_persist_ai_repair_proposals_to_cache` called after Step 14 visual check, threading `visual_check_passed` from overflow result and `auto_cache` from settings | `src/phase_z2_pipeline.py:718-775, 5534-5550` | # Residual root cause (1 axis) **Axis R — Router read-path fingerprint enforcement gap.** - `route_ai_fallback(cache_key, ...)` accepts no `fingerprints` parameter (`src/phase_z2_ai_fallback/router.py:43-53`). - Inside the router, `cached = read_proposal(cache_key)` is called WITHOUT `fingerprints=...` (`src/phase_z2_ai_fallback/router.py:66`). - Step 12 already computes the three fingerprints (`contract_sha` / `partial_sha` / `catalog_sha`) and stores them in the per-unit record (`src/phase_z2_ai_fallback/step12.py:179-185`), but never threads them through to the router. - Self-acknowledged TODO at `src/phase_z2_ai_fallback/step12.py:48-51`: *"the router's existing `read_proposal(cache_key)` continues to perform exact-match lookup only (fuzzy is deferred per Stage 2 plan); read-side fingerprint validation through the router is a follow-up axis."* **Consequence**: When a frame contract / partial template / catalog payload changes, the save-side correctly tags new entries with fresh fingerprints, but lookups continue to return stale entries because the read path does not compare fingerprints. The invalidation contract documented in `cache.py:28-44` is enforceable only at the *caller* of `read_proposal`, and the production caller (router) does not pass fingerprints. Issue body explicit guardrail "contract/partial 변경 시 invalidate (cache 일관성)" therefore is half-enforced: tested in unit isolation, not enforced in production read path. # Out of scope (explicit exclusions, carve-out boundary) - Re-stirring `cache.py`, `signature.py`, save-side pipeline wiring, `--auto-cache` semantics, `.gitignore`, or `data/frame_cache/.gitkeep` (all merged in `1186ad8` — see carve-out table). - AI call itself / prompt redesign (IMP-33 closed at `c864fe0`). - New `route_ai_fallback` call sites beyond current production site `src/phase_z2_ai_fallback/step12.py:194-203`. - Fuzzy match secondary tier (issue marks "옵션" — deferred per Stage 2 plan). - Cache → catalog promotion (R4 wave). - `mdx_normalizer` Stage 0 integration (separate lock 2026-05-08). - `user_approved` UX gate (documented design choice — pipeline relies on `auto_cache` opt-in per IMP-46 u5; see `src/phase_z2_pipeline.py:5538-5542`). - Step 17 cache integration (Step 17 entry is structurally blocked behind IMP-34/35 prerequisites per `IMP-17-CARVE-OUT.md:52`). # Proposed scope-lock (residual axis only) - Extend `route_ai_fallback` signature with an optional `fingerprints: dict | None = None` keyword-only kwarg. Default `None` preserves current router behavior and back-compat with existing `test_router.py` cases. - Pass `fingerprints` through to `read_proposal(cache_key, fingerprints=fingerprints)` (cache.py:108 already supports this kwarg; no `cache.py` edit needed). - Thread `fingerprints` from `src/phase_z2_ai_fallback/step12.py:194-203` `route_ai_fallback(...)` call. Source = the existing `fingerprints` dict already computed at `step12.py:179-185`. No new computation — pure reuse. - Update `tests/phase_z2_ai_fallback/test_router.py` with three new cases: 1. cache-hit with matching fingerprints → returns cached (validates short-circuit preserved) 2. cache-hit with mismatched fingerprints → `read_proposal` returns `None` → falls through to client path (validates strict-equality invalidation reaches production) 3. cache-hit with `fingerprints=None` (legacy back-compat) → returns cached without comparison (preserves existing router test surface) - Update `tests/phase_z2_ai_fallback/test_step12.py` to assert `fingerprints` is forwarded to `route_ai_fallback` (mock router, inspect kwargs). - No new modules, no new files. Touched files: `src/phase_z2_ai_fallback/router.py` (signature + one call), `src/phase_z2_ai_fallback/step12.py` (one call site), `tests/phase_z2_ai_fallback/test_router.py` (3 cases), `tests/phase_z2_ai_fallback/test_step12.py` (1-2 assertions). # Guardrails (Stage 2 binding) - **carve-out caveat** (`project_imp46_carveout_caveat`): files modified in `1186ad8` are NOT in scope for content rewrites. Only the *call site* in `step12.py:194-203` (the `route_ai_fallback(...)` invocation) gets one kwarg added. No re-touch of the fingerprints computation block (`step12.py:179-185`). - **AI isolation** (`feedback_ai_isolation_contract`): cache layer adds no AI call; router still does not import `save_proposal`; `test_router_does_not_import_save_proposal` (test_router.py:153) invariant holds. AST isolation test (`tests/phase_z2_ai_fallback/test_ast_isolation.py`) keeps the import whitelist intact. - **PZ-1 invariant**: flag-off and route-mismatch short-circuits execute BEFORE fingerprint comparison (router lines 61-65 unchanged).

[Codex #1] Stage 1 problem-review -- IMP-46 (#62)

Scope-lock result: Claude r1 is correct. The #76 absorption already landed the cache backend, structural signature, save gates, auto-cache flag, and save-side fingerprint persistence. The remaining IMP-46 work should not re-open those areas.

Residual root cause verified: the production cache read path is not fingerprint-aware. src/phase_z2_ai_fallback/cache.py:108-148 already supports read_proposal(key, fingerprints=...) and invalidates on strict stored-vs-supplied mismatch. src/phase_z2_ai_fallback/step12.py:179-185 computes and records contract_sha, partial_sha, and catalog_sha. But src/phase_z2_ai_fallback/router.py:43-53 accepts no fingerprints argument and src/phase_z2_ai_fallback/router.py:66 calls read_proposal(cache_key) with the default fingerprints=None, which src/phase_z2_ai_fallback/cache.py:38-44 documents as no comparison. src/phase_z2_ai_fallback/step12.py:195-203 calls the router without passing the already-computed fingerprints.

Consequence: stale cache entries can be returned after contract / partial / catalog changes whenever the structural signature is unchanged. The cache layer can enforce invalidation, but the production router caller is not supplying the invalidation inputs.

Scope-locked implementation axis:

• Add router read-path fingerprint enforcement only: extend route_ai_fallback to accept fingerprints: dict | None = None, pass it to read_proposal(cache_key, fingerprints=fingerprints), and thread record["fingerprints"] from Step 12 into the router call.
• Add focused router/Step 12 regression coverage proving mismatched fingerprints miss cache and matching fingerprints hit cache through the router path.
• Do not alter signature axes, JSON path format, save gates, auto-cache semantics, fuzzy lookup, AI request behavior, catalog promotion, or sample-specific logic.

Missing-file / wrong-assumption check: no missing required files found for this residual axis. The relevant files exist at src/phase_z2_ai_fallback/router.py, src/phase_z2_ai_fallback/step12.py, src/phase_z2_ai_fallback/cache.py, src/phase_z2_ai_fallback/signature.py, src/phase_z2_pipeline.py, src/config.py, data/frame_cache/.gitkeep, .gitignore, and docs/architecture/IMP-17-CARVE-OUT.md.

[Claude #2] Stage 2 simulation-plan — IMP-46 (#62) router read-path fingerprint enforcement (post-#76-absorption, Axis R only)

Scope = Stage 1 allowed_edits + allowed_tests verbatim. All #76-absorbed territory (signature axes / JSON cache path / cache.py invalidation comparator / save-side wiring / --auto-cache / catalog promotion) FROZEN.

=== AXIS COVERAGE ===

• router.py signature gap (R-1) → u1
• router.py read_proposal call site (R-2) → u1
• existing test_router.py 6 lambda mocks @ :89/102/111/124/137/146 (signature-change collateral) → u1
• step12.py route_ai_fallback call site @ :195-203 (R-3) → u3
• router-level miss test (mismatched fingerprints → cache miss) → u2
• router-level hit test (matching fingerprints → cache hit) → u2
• step12 integration test (end-to-end forwarding) → u4

=== IMPLEMENTATION_UNITS ===

• id: u1
  summary: Add fingerprints=None kwarg to route_ai_fallback signature, forward to read_proposal, repair 6 existing router test lambdas to accept the kwarg via lambda key, **_:.
  files: [src/phase_z2_ai_fallback/router.py, tests/phase_z2_ai_fallback/test_router.py]
  tests: [tests/phase_z2_ai_fallback/test_router.py]
  estimate_lines: 25
• id: u2
  summary: Add router-level miss + hit cases — mismatched fingerprints → cache miss → client called; matching fingerprints → cache hit → client NOT called.
  files: [tests/phase_z2_ai_fallback/test_router.py]
  tests: [tests/phase_z2_ai_fallback/test_router.py]
  estimate_lines: 30
• id: u3
  summary: Step 12 forwards record["fingerprints"] into route_ai_fallback(fingerprints=...) at step12.py:195-203.
  files: [src/phase_z2_ai_fallback/step12.py]
  tests: [tests/phase_z2_ai_fallback/test_step12.py]
  estimate_lines: 4
• id: u4
  summary: Step12 integration test patching step12_mod.route_ai_fallback with MagicMock; assert call_args.kwargs["fingerprints"] equals record["fingerprints"] dict built at step12.py:179-185.
  files: [tests/phase_z2_ai_fallback/test_step12.py]
  tests: [tests/phase_z2_ai_fallback/test_step12.py]
  estimate_lines: 25

=== PER-UNIT RATIONALE ===

• u1: cache.py:38-44 already supports fingerprints=None no-op default. Router gap = missing kwarg + forward only. Optional kwarg (not positional) preserves non-step12 callers per Stage 1 Q2.
• u2: cache.py:145-148 strict equality. Tests router-level only (mock read_proposal, no filesystem) per feedback_scope_qualified_verification. On-disk invalidation already covered by #76 test_cache_invalidation.py.
• u3: 1 kwarg added to existing call. record["fingerprints"] already built.
• u4: Stage 1 Q1 resolved → mismatch returns None → router falls through to AI call (existing miss path, no typed signal needed).

=== OUT OF SCOPE (Stage 1 lock) ===
signature.py, JSON cache path format, cache.py comparator, save-side _persist_ai_repair_proposals_to_cache, --auto-cache CLI / settings.ai_fallback_auto_cache, fuzzy lookup, sample-specific logic, AI request behaviour, catalog promotion, u1~u6 of original IMP-46 plan (all absorbed in commit 1186ad8).

=== ROLLBACK ===
Two-file revert (router.py + step12.py) restores pre-change behaviour. No on-disk cache schema change; existing cache files remain readable under default fingerprints=None.

=== SIDE EFFECTS ===

• Existing cache entries written by #76 get strict invalidation on next contract/partial/catalog change — expected.
• Non-step12 callers keep working under default fingerprints=None (cache.py:42-44 back-compat).
• No follow-up issue required.

=== EVIDENCE ===

• router.py:43-53 — signature lacks fingerprints kwarg.
• router.py:66 — read_proposal(cache_key) lacks fingerprints arg.
• cache.py:38-44, 108-148 — read_proposal supports optional fingerprints with strict-equality.
• step12.py:179-185 — record["fingerprints"] already constructed.
• step12.py:195-203 — call site does not forward fingerprints.
• test_router.py:89/102/111/124/137/146 — 6 single-arg read_proposal lambdas (verified via grep).
• test_step12.py:291-360 — existing fingerprints record tests confirm dict shape.
• Memory project_imp46_carveout_caveat honoured: zero edits to signature.py / cache.py / save-side wiring.

  files: [tests/phase_z2_ai_fallback/test_step12.py]
  tests: [tests/phase_z2_ai_fallback/test_step12.py]
  estimate_lines: 25

=== PER-UNIT RATIONALE ===

• u1: Covers router.py:43-53 signature gap and router.py:66 read_proposal call gap. Optional kwarg preserves non-Step12 callers while enabling strict lookup for callers that have fingerprints.
• u2: Scope-qualified router-level tests cover the residual read path only. Existing cache.py:108-148 already owns filesystem parsing and strict fingerprint equality.
• u3: Covers step12.py:195-203 caller gap using the fingerprints produced at step12.py:179-185. This is the only production Step 12 edit required by the Stage 1 lock.
• u4: Covers end-to-end forwarding at Step12 level without changing AI request behavior. The expected stale-cache behavior remains ordinary cache miss followed by the existing client path.

=== OUT OF SCOPE ===
signature.py structural axes, data/frame_cache path format, cache.py invalidation comparator, save-side cache persistence, --auto-cache semantics, fuzzy lookup, AI request behavior, catalog promotion, sample-specific handling, and all #76-absorbed IMP-46 units remain frozen.

=== ROLLBACK STRATEGY ===
Revert only the four planned files if Stage 3 regresses. No data files, cache artifacts, templates, catalog files, or settings should be committed for this issue.

Side effects: the required baseline is red because .env:4 sets AI_FALLBACK_ENABLED=true, overriding the locked Settings default at src/config.py:19 and violating the expectation asserted at tests/test_phase_z2_ai_fallback_config.py:22-26.

=== PER-UNIT RATIONALE ===

• u1: Correct residual axis. router.py:43-68 currently has no fingerprints kwarg and calls read_proposal(cache_key) without invalidation input.
• u2: Correct router-level scope. cache.py:108-148 already enforces strict equality when fingerprints are supplied.
• u3: Correct Step 12 wire. step12.py:179-185 builds fingerprints and step12.py:195-203 currently omits them from route_ai_fallback.
• u4: Correct integration target. The test should prove forwarding only, not re-test cache.py invalidation.
• u5: NO. The mechanism is false: src/config.py:37 sets model_config env_file=.env, so deleting os.environ does not stop fresh Settings() from reading .env:4 AI_FALLBACK_ENABLED=true. A session autouse fixture also cannot reliably predate module-import global settings construction at src/config.py:40.

=== OUT OF SCOPE ===
signature.py axes, JSON cache path, cache.py invalidation comparator, save-side cache gates, --auto-cache semantics, fuzzy lookup, AI request behavior, catalog promotion, and all #76 absorbed units remain out of scope.

=== ROLLBACK STRATEGY ===
Revert only the router.py, step12.py, and focused test-file edits for this axis. Do not edit .env; replace u5 with a plan that neutralizes Settings env_file or patches the imported settings objects inside the affected tests.

[Claude #4] Stage 2 simulation-plan — IMP-46 (#62) Axis R r3 (post Codex #3 NO)

Delta vs prior r1/r2: u5 (tests/conftest.py AI_FALLBACK_ENABLED scrubber) DROPPED. Stage 1 allowed_edits = router.py + step12.py only; allowed_tests = router-level + step12 integration only. conftest.py is scope creep both axes. The 4 .env-driven baseline reds (.env:4 AI_FALLBACK_ENABLED=true) are pre-existing, axis-orthogonal, out-of-scope; router tests monkeypatch.setattr(router_mod.settings, "ai_fallback_enabled", ...) so .env is irrelevant for u1u4 (verified: pytest tests/phase_z2_ai_fallback/test_router.py = 9 passed). u1u4 unchanged.

=== IMPLEMENTATION_UNITS ===

• id: u1
  summary: Add fingerprints: dict | None = None kwarg-only param to route_ai_fallback (router.py:43-53, appended after client); forward via read_proposal(cache_key, fingerprints=fingerprints) (router.py:66); repair 6 router-test lambdas at test_router.py:89/102/111/124/137/146 from lambda key: ... to lambda key, **_: .... Carry-fix shares the same decision unit (intermediate state baseline-red).

• id: u2
  summary: Router-level fingerprint coverage in test_router.py — (a) mismatched fingerprints → read_proposal returns None → client.request_proposal IS called; (b) matching → cached returned, client NOT called; (c) fingerprints=None legacy → cached returned. Each mocks read_proposal with a spy asserting the fingerprints kwarg. Each test docstring declares scope = router-level.

Positive case (AI-eligible _ai_unit() → forward, shape {contract_sha, partial_sha, catalog_sha}) + negative case (skipped unit → router not called, record["fingerprints"] is None).

=== PER-UNIT RATIONALE ===

• u1: cache.py:108-148 already supports fingerprints=None no-op default; strict-equality comparator at cache.py:145-148. Kwarg + default None preserves any non-step12 callers (Stage 1 Q2 lock).
• u2: 3-case mirror of cache.py strict-equality. On-disk invalidation already covered by #76 test_cache_invalidation.py — not duplicated.
• u3: 1 kwarg added. Pure forward; no new computation.
• u4: Stage 1 Q1 resolution → mismatch returns None → router falls through to existing AI miss path (router.py:74-83); no typed cache-stale signal needed.

=== OUT OF SCOPE (Stage 1 lock + #76 absorbed) ===
signature.py / data/frame_cache JSON path / cache.py comparator / save-side _persist_ai_repair_proposals_to_cache / --auto-cache CLI / settings.ai_fallback_auto_cache / fuzzy lookup / catalog promotion / .env:4 toggle + induced 4 baseline reds (feedback_demo_env_toggle_policy; out-of-scope follow-up).

=== ROLLBACK ===
Per-unit revert; u3 depends on u1 (revert u3 first). u2+u4 additive. No new files. No on-disk cache schema change; #76 cache JSONs remain readable under default fingerprints=None.

=== EVIDENCE ===

• router.py:43-53,66 — signature lacks fingerprints; read_proposal call lacks forward (Read).
• cache.py:38-44,108-148 — fingerprints kwarg + strict-equality already present (Read).
• step12.py:179-185 — record["fingerprints"] built; step12.py:194-203 call site does not forward (Read).
• test_router.py:89/102/111/124/137/146 — 6 single-arg lambda key: monkeypatches (Grep, 6 hits).
• test_step12.py:62-76 — _call + MagicMock pattern for u4 (Read).
• .env:4 AI_FALLBACK_ENABLED=true (Bash grep). pytest tests/test_phase_z2_ai_fallback_config.py tests/test_imp47b_step12_ai_wiring.py = 4 failed (pre-existing) / 6 passed. Axis-orthogonal.
• pytest tests/phase_z2_ai_fallback/test_router.py = 9 passed (router scope clean).
• Memory rules: project_imp46_carveout_caveat (no signature.py / cache.py / save-side edits), feedback_demo_env_toggle_policy (.env untouched), feedback_scope_qualified_verification (router-level vs step12-level), feedback_one_step_per_turn.

  tests: [tests/phase_z2_ai_fallback/test_step12.py]
  estimate_lines: 25

=== PER-UNIT RATIONALE ===

• u1: Directly closes the binding Stage 1 read-path gap at router.py:43-66. cache.py:108-148 already has the strict invalidation API; router is the missing caller.
• u2: Covers deterministic cache-hit/cache-miss behavior at router scope without touching on-disk cache semantics already covered in test_cache_invalidation.py.
• u3: Uses the fingerprints producer already present at step12.py:179-185 and forwards it at the only current Step 12 router call at step12.py:195-203.
• u4: Covers Step 12 end-to-end forwarding and the negative skipped-record path, matching the allowed_tests contract for router-level plus step12-level scope.

Out-of-scope notes:

• No edits to signature.py, cache.py invalidation logic, save-side cache persistence, auto-cache, fuzzy lookup, catalog promotion, AI request behavior, or sample-specific artifacts.
• No tests/conftest.py scrubber: baseline reds are environment/config state, not Axis R implementation scope.
• All units are <=50 estimated lines and <=3 files; total implementation scope is router.py, step12.py, test_router.py, and test_step12.py only.

Rollback strategy:

• Revert the four scoped files only; no generated cache files or catalog/template data should be touched by this plan.

• Current router signature has no fingerprints parameter and calls read_proposal(cache_key) without fingerprints at router.py:43-66.
• Step 12 already builds contract_sha, partial_sha, and catalog_sha into record["fingerprints"] at step12.py:179-185, but does not pass fingerprints to route_ai_fallback at step12.py:195-203.
• cache.py already documents and implements strict equality invalidation when fingerprints are supplied, and no comparison when fingerprints=None.
• Existing router read_proposal monkeypatches at test_router.py:89,102,111,124,137,146 must be widened when u1 changes the call shape.
• The u1-u4 plan covers the full residual Stage 1 Axis R contract and does not reopen #76 absorbed cache signature/save/fuzzy/catalog areas.

[Claude #1] Stage 3 code-edit — IMP-46 (#62) Axis R u1

Executing unit: u1

unit_executed

• id: u1
• summary: Add optional fingerprints kwarg to route_ai_fallback after client, forward it into read_proposal(cache_key, fingerprints=fingerprints), and repair the 6 existing read_proposal monkeypatch lambdas in test_router.py to accept the new kwarg (carry-fix bundled in u1 per Stage 2 plan to avoid mid-state baseline-red).

files_changed

• src/phase_z2_ai_fallback/router.py
• tests/phase_z2_ai_fallback/test_router.py

diff_summary

• src/phase_z2_ai_fallback/router.py:43-66
  • Added kwarg-only parameter fingerprints: dict | None = None after client in route_ai_fallback signature.
  • Forwarded fingerprints into existing cache call: read_proposal(cache_key, fingerprints=fingerprints).
  • Expanded docstring with the IMP-46 #62 Axis R rationale: contract / partial / catalog SHA mismatch must invalidate stale cache entries; None preserves legacy no-comparison behaviour.
• tests/phase_z2_ai_fallback/test_router.py (6 lambdas at lines 89, 102, 111, 124, 137, 146 in baseline)
  • lambda key: ... → lambda key, **_: ... for every monkeypatch.setattr(router_mod, "read_proposal", ...) site (4× None, 1× cached, 1× bad_cached).
  • Pure carry-fix — no test assertion changes in u1; new fingerprint coverage lands in u2.

scope verification

• Stage 1 allowed_edits honoured:
  • router.py: extend route_ai_fallback(..., fingerprints: dict | None = None) ✓
  • router.py: pass fingerprints to read_proposal(cache_key, fingerprints=fingerprints) ✓
  • step12.py: untouched (deferred to u3) ✓
• Out-of-scope untouched: cache.py, signature.py, _persist_ai_repair_proposals_to_cache, --auto-cache, Settings.ai_fallback_auto_cache, AI request behaviour, catalog promotion, all #76-absorbed units.
• IMP-47B (#76) commit 1186ad8 cache carve-out: not stirred (memory: project_imp46_carveout_caveat).

scope-qualified verification

• Scope: router-level only (tests/phase_z2_ai_fallback/test_router.py).
• Command: python -m pytest tests/phase_z2_ai_fallback/test_router.py -q
• Result: 9 passed in 0.04s (matches Stage 2 baseline of 9 passed; signature widening + lambda carry-fix preserves green).

remaining_units

• u2: Add router-level cache read coverage (mismatched fingerprints miss, matching fingerprints hit, legacy None hit) with assertions on the read_proposal fingerprints kwarg and router-level scope docstrings.
• u3: Forward record["fingerprints"] into the existing route_ai_fallback call in src/phase_z2_ai_fallback/step12.py AI-eligible path.
• u4: Step 12 integration coverage proving route_ai_fallback receives exactly record["fingerprints"] for AI-eligible units and skipped / non-AI records do not call the router.

follow_up_issue_candidates

None this turn. No scope-lock-external axis observed during u1. Stage 2 already records tests/conftest.py AI_FALLBACK_ENABLED scrubber and the 4 .env-driven baseline-red items as separate follow-up axes.

guardrails honoured

• feedback_workflow_atomicity_rules: 1 commit = 1 decision unit (u1 carry-fix bundled to avoid mid-state baseline-red).
• feedback_one_step_per_turn: only u1 executed; u2~u4 deferred.
• feedback_no_hardcoding: read-path contract widened (process), not artifact patched.
• feedback_scope_qualified_verification: pytest scope declared router-level.
• feedback_factual_verification: every change cites file + line range.
• DO NOT commit or push — per Stage 3 turn directive. Gitea comment is the deliverable.

[Codex #1] Stage 3 code-edit review -- IMP-46 (#62) Axis R u1

Scope: verified only the single executed unit, u1.

Verdict: u1 is correct. route_ai_fallback now accepts optional fingerprints after client and forwards that value into read_proposal(cache_key, fingerprints=fingerprints). The six pre-existing router test monkeypatches now accept the new keyword, preserving router-test compatibility without adding u2 coverage early.

Scope lock checked: step12.py, cache.py, and signature.py have no scoped diff in this verification. The implemented changes are limited to src/phase_z2_ai_fallback/router.py and tests/phase_z2_ai_fallback/test_router.py.

[Claude #2] Stage 3 code-edit — IMP-46 (#62) Axis R u2

Executing unit: u2

unit_executed

• id: u2
• summary: Add router-level cache read coverage for (a) mismatched fingerprints → miss → client invoked, (b) matching fingerprints → hit → client NOT invoked, (c) legacy fingerprints=None → hit → client NOT invoked. Each new test captures the fingerprints kwarg actually passed to read_proposal via a keyword-spy, asserts strict equality against the caller-supplied dict (or None), and declares router-level scope in its docstring per Stage 2 plan.

files_changed

• tests/phase_z2_ai_fallback/test_router.py

diff_summary

• tests/phase_z2_ai_fallback/test_router.py — three new test functions inserted between test_router_validates_cached_proposal and test_router_calls_client_and_returns_validated_proposal:
  • test_router_forwards_fingerprints_and_misses_on_mismatch — supplies fingerprints={"contract_sha": "aaa", "partial_sha": "bbb", "catalog_sha": "ccc"}, spy read_proposal returns None (simulating strict-equality SHA mismatch), router proceeds to call client, captured kwarg equals supplied dict.
  • test_router_forwards_fingerprints_and_hits_on_match — supplies fingerprints={"contract_sha": "xxx", "partial_sha": "yyy", "catalog_sha": "zzz"}, spy read_proposal returns cached proposal (simulating strict-equality match), router short-circuits, client.request_proposal not called, captured kwarg equals supplied dict.
  • test_router_forwards_fingerprints_none_for_legacy_callers — caller omits fingerprints, spy read_proposal returns cached proposal, captured kwarg is None, client not called (legacy no-invalidation behaviour preserved).
• No production code touched in u2. src/phase_z2_ai_fallback/router.py already accepts and forwards fingerprints per u1.
• The 6 pre-existing read_proposal monkeypatch lambdas (already repaired in u1 with lambda key, **_:) remain unchanged.

scope verification

• Stage 2 plan per_file_changes for u2 honoured: tests/phase_z2_ai_fallback/test_router.py only — 3 new fingerprint scenarios added; no existing test assertion changed.
• Stage 1 allowed_edits honoured: u2 lives entirely in the router-level test file; production surface untouched until u3.
• Out-of-scope untouched this turn: src/phase_z2_ai_fallback/router.py, src/phase_z2_ai_fallback/step12.py, tests/phase_z2_ai_fallback/test_step12.py, cache.py, signature.py, _persist_ai_repair_proposals_to_cache, --auto-cache, Settings.ai_fallback_auto_cache, AI request behaviour, catalog promotion, all #76-absorbed units.
• IMP-47B (#76) commit 1186ad8 cache carve-out: not stirred (memory: project_imp46_carveout_caveat).
• AI isolation contract: untouched (memory: feedback_ai_isolation_contract).
• No hardcoding (memory: feedback_no_hardcoding): test fingerprint values are inline test fixtures, not sample-specific MDX or frame DB leakage.

scope-qualified verification

• Scope: router-level only (tests/phase_z2_ai_fallback/test_router.py).
• Command: python -m pytest tests/phase_z2_ai_fallback/test_router.py -q
• Result: 12 passed in 0.49s (u1 baseline 9 passed + 3 new u2 scenarios = 12). No regressions in pre-existing 9 tests.

[Codex #2] Stage 3 code-edit review -- IMP-46 (#62) Axis R u2

Scope: verified only the single executed unit, u2.

Verdict: u2 is correct. The router-level test file adds the three required fingerprint scenarios: mismatch simulated as cache miss with client invocation, match simulated as cache hit with no client invocation, and legacy omitted fingerprints forwarded as None. Each new test captures the actual fingerprints kwarg passed to read_proposal and declares router-level scope in its docstring.

Scope lock checked: production code changes remain limited to the previously verified u1 router forwarding. This u2 verification found no scoped diff in step12.py, test_step12.py, cache.py, or signature.py, so u3/u4 and cache/signature territory were not touched by this unit.

Executing unit: u3

• summary: Forward the fingerprints dict already built in src/phase_z2_ai_fallback/step12.py (lines 179-185) into the existing route_ai_fallback call at the AI-eligible path (lines 195-203). u1 widened the router signature; u3 connects the producer to the consumer so contract / partial / catalog SHA mismatches actually reach the cache invalidation gate end-to-end.

[Codex #3] Stage 3 code-edit review -- IMP-46 (#62) Axis R u3

Scope: verified only the single executed unit, u3.

Verdict: u3 is correct. src/phase_z2_ai_fallback/step12.py now forwards the existing fingerprints local into the existing route_ai_fallback(...) call on the AI-eligible path. That local is the same dict assigned to record["fingerprints"] immediately before the router call, so the Step 12 producer is now connected to the router read-path invalidation input without changing fingerprint computation, cache semantics, or AI request behavior.

Scope lock checked: this unit's scoped production diff is the one-line Step 12 forwarding change. The already-present u1/u2 router and router-test changes remain in the combined diff, but u3 did not add cache, signature, save-side, auto-cache, or test-step12 changes.

[Claude #4] Stage 3 code-edit — IMP-46 (#62) Axis R u4

Executing unit: u4

unit_executed

• id: u4
• summary: Add Step 12 integration coverage proving route_ai_fallback receives exactly record["fingerprints"] for an AI-eligible unit, and proving skipped / non-AI records do not call the router and keep record["fingerprints"] as None. Locks the end-to-end producer→consumer wiring landed in u3 (step12.py:179-185 builds the fingerprints dict, stamps it onto record["fingerprints"] at step12.py:185, and forwards the same object into the router via fingerprints= at step12.py:203). u1+u2 covered router-level surface; u4 covers the Step 12 integration surface.

files_changed

• tests/phase_z2_ai_fallback/test_step12.py

diff_summary

• tests/phase_z2_ai_fallback/test_step12.py — appended a new section header IMP-46 u4 — Step 12 ↔ router fingerprints forwarding (integration scope) and 5 new test functions after test_production_non_provisional_reject_skipped_before_route_gate:
  • test_router_receives_exactly_record_fingerprints_for_ai_eligible — strict equality router.call_args.kwargs["fingerprints"] == recs[0]["fingerprints"] for an AI-eligible unit with caller-supplied contract / partial / catalog_value; also re-derives the expected SHA256 of contract + partial via hashlib.sha256(json.dumps(..., sort_keys=True, ensure_ascii=False).encode("utf-8")).hexdigest() and asserts the forwarded dict matches the canonical form.
  • test_router_fingerprints_kwarg_is_present_even_with_default_catalog — asserts "fingerprints" in router.call_args.kwargs (not relying on the router's default None) and that the 3 keys are present with catalog_sha == "" sentinel when no catalog_sha_loader is supplied; proves step12.py:203 forwards explicitly rather than letting the router-side default apply.
  • test_router_not_called_and_fingerprints_none_for_non_provisional — non-provisional unit → router.assert_not_called(), rec["fingerprints"] is None, rec["cache_key"] is None, rec["skip_reason"] == "not_provisional".
  • test_router_not_called_and_fingerprints_none_for_non_ai_route — light_edit (non-AI route) → router.assert_not_called(), rec["fingerprints"] is None, rec["cache_key"] is None, rec["skip_reason"] == "route_not_ai_adaptation:deterministic_minor_adjustment".
  • test_mixed_units_router_receives_fingerprints_only_for_ai_eligible — mixed batch of [not_provisional, light_edit, _ai_unit()] → router.assert_called_once(), forwarded fingerprints kwarg matches recs[2]["fingerprints"], and skipped records carry fingerprints is None.
• Each new test declares step12-integration scope in its docstring per Stage 2 plan.
• No production source touched this turn. route_ai_fallback forwarding at step12.py:203 (u3) and read_proposal(cache_key, fingerprints=fingerprints) at router.py:72 (u1) remain unchanged.

SHA256 expectations are re-derived from the same canonical JSON-sort form used by the producer (json.dumps(..., sort_keys=True, ensure_ascii=False).encode("utf-8")) rather than hardcoded hex literals.
• 1 commit = 1 decision unit (memory: feedback_workflow_atomicity_rules): u4 = test_step12.py only.

[Claude #4] Stage 3 code-edit — IMP-46 (#62) Axis R u4 Executing unit: u4 ## unit_executed - id: u4 - summary: Add Step 12 integration coverage proving `route_ai_fallback` receives exactly `record["fingerprints"]` for an AI-eligible unit, and proving skipped / non-AI records do not call the router and keep `record["fingerprints"]` as `None`. Locks the end-to-end producer→consumer wiring landed in u3 (step12.py:179-185 builds the fingerprints dict, stamps it onto `record["fingerprints"]` at step12.py:185, and forwards the same object into the router via `fingerprints=` at step12.py:203). u1+u2 covered router-level surface; u4 covers the Step 12 integration surface. ## files_changed - `tests/phase_z2_ai_fallback/test_step12.py` ## diff_summary - `tests/phase_z2_ai_fallback/test_step12.py` — appended a new section header `IMP-46 u4 — Step 12 ↔ router fingerprints forwarding (integration scope)` and 5 new test functions after `test_production_non_provisional_reject_skipped_before_route_gate`: - `test_router_receives_exactly_record_fingerprints_for_ai_eligible` — strict equality `router.call_args.kwargs["fingerprints"] == recs[0]["fingerprints"]` for an AI-eligible unit with caller-supplied `contract` / `partial` / `catalog_value`; also re-derives the expected SHA256 of contract + partial via `hashlib.sha256(json.dumps(..., sort_keys=True, ensure_ascii=False).encode("utf-8")).hexdigest()` and asserts the forwarded dict matches the canonical form. - `test_router_fingerprints_kwarg_is_present_even_with_default_catalog` — asserts `"fingerprints" in router.call_args.kwargs` (not relying on the router's default `None`) and that the 3 keys are present with `catalog_sha == ""` sentinel when no `catalog_sha_loader` is supplied; proves step12.py:203 forwards explicitly rather than letting the router-side default apply. - `test_router_not_called_and_fingerprints_none_for_non_provisional` — non-provisional unit → `router.assert_not_called()`, `rec["fingerprints"] is None`, `rec["cache_key"] is None`, `rec["skip_reason"] == "not_provisional"`. - `test_router_not_called_and_fingerprints_none_for_non_ai_route` — `light_edit` (non-AI route) → `router.assert_not_called()`, `rec["fingerprints"] is None`, `rec["cache_key"] is None`, `rec["skip_reason"] == "route_not_ai_adaptation:deterministic_minor_adjustment"`. - `test_mixed_units_router_receives_fingerprints_only_for_ai_eligible` — mixed batch of `[not_provisional, light_edit, _ai_unit()]` → `router.assert_called_once()`, forwarded fingerprints kwarg matches `recs[2]["fingerprints"]`, and skipped records carry `fingerprints is None`. - Each new test declares **step12-integration scope** in its docstring per Stage 2 plan. - No production source touched this turn. `route_ai_fallback` forwarding at `step12.py:203` (u3) and `read_proposal(cache_key, fingerprints=fingerprints)` at `router.py:72` (u1) remain unchanged. ```diff @@ tests/phase_z2_ai_fallback/test_step12.py (append, +102 lines) +# --------------------------------------------------------------------------- +# IMP-46 u4 — Step 12 ↔ router fingerprints forwarding (integration scope) +# --------------------------------------------------------------------------- + +def test_router_receives_exactly_record_fingerprints_for_ai_eligible(monkeypatch): + ... + assert forwarded == record_fingerprints + +def test_router_fingerprints_kwarg_is_present_even_with_default_catalog(monkeypatch): + ... + assert "fingerprints" in router.call_args.kwargs + +def test_router_not_called_and_fingerprints_none_for_non_provisional(monkeypatch): + ... + router.assert_not_called() + assert recs[0]["fingerprints"] is None + +def test_router_not_called_and_fingerprints_none_for_non_ai_route(monkeypatch): + ... + router.assert_not_called() + assert recs[0]["fingerprints"] is None + +def test_mixed_units_router_receives_fingerprints_only_for_ai_eligible(monkeypatch): + ... + router.assert_called_once() + assert forwarded == recs[2]["fingerprints"] + assert recs[0]["fingerprints"] is None + assert recs[1]["fingerprints"] is None ``` ## scope verification - Stage 2 plan `per_file_changes` for u4 honoured: - `test_step12.py — add integration coverage asserting router receives record["fingerprints"] for AI-eligible, None for skipped/non-AI` ✓ - Stage 1 `allowed_edits` honoured: u4 lives entirely in `tests/phase_z2_ai_fallback/test_step12.py`; production surface (`router.py`, `step12.py`, `cache.py`, `signature.py`) untouched this turn. - This-turn scoped diff = `tests/phase_z2_ai_fallback/test_step12.py` only (+102 lines, 5 new test functions + 1 section header).

[Codex #4] Stage 3 code-edit review -- IMP-46 (#62) Axis R u4

Scope: verified only the single executed unit, u4.

Verdict: u4 is correct. The Step 12 integration test file adds the required coverage proving that AI-eligible records forward the produced fingerprints dict into route_ai_fallback, and that skipped/non-AI records do not call the router and keep record["fingerprints"] as None. The test coverage is scoped to tests/phase_z2_ai_fallback/test_step12.py; the combined working diff still includes the already-verified u1-u3 changes, but u4 itself adds only Step 12 integration tests.

Scope lock checked: no u4 changes were made to production source, cache invalidation logic, signature generation, save-side cache behavior, auto-cache settings, AI request behavior, or catalog promotion. The production wiring from u3 remains present at src/phase_z2_ai_fallback/step12.py:195-203.

• tests/phase_z2_ai_fallback/test_step12.py:588-604 adds mixed-batch coverage proving only the AI-eligible unit calls the router and forwards fingerprints matching recs[2]["fingerprints"]; skipped records keep fingerprints is None.

Production-line change count = 13 lines (router.py +6/-1, step12.py +1/-0) — within u1+u3 estimate (25+3).

Unit	Plan (Stage 2)	Actual file:line	Match
u1	router.py:43-66 add fingerprints kwarg-only after client, forward to read_proposal(cache_key, fingerprints=fingerprints)	router.py:53 (new kwarg), router.py:72 (forward); 6 test_router.py lambdas patched to key, **_ (lines 89, 102, 184, 205, 218, 227)	✅

■ Carve-out boundary verification (vs #76 commit 1186ad8)

git diff against the protected territory — clean:

File	git diff output	Status

src/phase_z2_ai_fallback/signature.py	empty	✅ untouched
src/phase_z2_ai_fallback/step12.py _persist_ai_repair_proposals_to_cache	only line 201 added (the fingerprints= forward), save-side fingerprint persistence at 179-185 unchanged	✅ producer untouched

feedback memory: project_imp46_carveout_caveat honored — no re-stirring of cache backend / signature axes / save gates / auto-cache / save-side fingerprint persistence.

■ No-hardcoding audit

Check	Result
`rg "mdx 03	hardcod
`rg "mdx 03	hardcod
Test SHA values	"aaa"/"bbb"/"ccc", "xxx"/"yyy"/"zzz", "c0ffee00" * 8 — fixture stand-ins, not extracted from any MDX 03/04/05 sample
Test inputs use _call(...) helper + FakeUnit factory	Production paths exercise generic _sha256_of(frame_contract) recomputation, not sample-pinned values

Generality check (RULE 0 / PIPELINE-CONSTRUCTION): the wiring is sample-agnostic — any frame_contract / figma_partial_json the upstream supplies produces fingerprints that flow through identical strict-equality cache invalidation. No frame-specific carve-out.

■ Regression check

• All 229 tests in tests/phase_z2_ai_fallback/ pass.
• Pre-existing baseline-red 4× (.env-driven AI_FALLBACK_ENABLED=true leak) — axis-orthogonal to Axis R (Stage 2 EXIT REPORT follow_up_candidates noted them as separate axis; out-of-scope per Stage 1 allowed_edits).
• Adjacent router consumers verified: tests/phase_z2_ai_fallback/test_router.py legacy callers (lines 184, 205, 218, 227) continue to call route_ai_fallback(**_call_kwargs(), client=client) with no fingerprints arg → read_proposal receives fingerprints=None → cache layer skips fingerprint comparison (legacy behavior preserved per router.py:62-65 docstring).

■ PZ rule application

• PZ-1 (AI=0 normal): route_ai_fallback short-circuits at flag-off / route-mismatch BEFORE prompt/client work (router.py:67-71). Unchanged by u1.
• PZ-2 (1 turn = 1 step): Stage 4 verification only this turn; no Stage 5 commit/push pre-GO.
• PZ-3 (no speculative): No NEW units invented this turn.
• PZ-4 (no silent shrink): Fingerprint-mismatch on cached entry → strict miss → router proceeds to client call (per u2 _misses_on_mismatch test). No silent fallback to stale value.
• RULE 4 (scope-qualified): every new test docstring carries "Scope: router-level" or "Integration scope:" prefix.
• RULE 9 (LLM classifies, code composes): this axis is pure code wiring, no AI surface widened.

■ Decision

PASS — Stage 4 round #1.

All 4 implementation units (u1 + u2 + u3 + u4) match Stage 2 plan exactly. Production touch surface = 13 lines across 2 files (router.py + step12.py). Test coverage = 8 new tests (3 router-level + 5 integration) all green. Carve-out boundary intact (cache.py / signature.py / save-side path untouched). No hardcoding regressions. Adjacent tests / full module regression green.

Ready for Stage 5 (commit + push) pending Codex consensus + user GO.

Unchanged by u1. - **PZ-2 (1 turn = 1 step)**: Stage 4 verification only this turn; no Stage 5 commit/push pre-GO. - **PZ-3 (no speculative)**: No NEW units invented this turn. - **PZ-4 (no silent shrink)**: Fingerprint-mismatch on cached entry → strict miss → router proceeds to client call (per u2 `_misses_on_mismatch` test). No silent fallback to stale value. - **RULE 4 (scope-qualified)**: every new test docstring carries `"Scope: router-level"` or `"Integration scope:"` prefix. - **RULE 9 (LLM classifies, code composes)**: this axis is pure code wiring, no AI surface widened. ■ Decision **PASS — Stage 4 round #1.** All 4 implementation units (u1 + u2 + u3 + u4) match Stage 2 plan exactly. Production touch surface = 13 lines across 2 files (router.py + step12.py). Test coverage = 8 new tests (3 router-level + 5 integration) all green. Carve-out boundary intact (cache.py / signature.py / save-side path untouched). No hardcoding regressions. Adjacent tests / full module regression green.

[Codex #1] Stage 4 test-verify -- IMP-46 (#62) Axis R u1-u4

Verification decision: PASS. Commit OK signal for the scoped IMP-46 Axis R files.

Scope-qualified test results:

• Router scope (u1 + u2): python -m pytest tests/phase_z2_ai_fallback/test_router.py -v -> 12 passed.
• Step 12 scope (u3 + u4): python -m pytest tests/phase_z2_ai_fallback/test_step12.py -v -> 29 passed.
• Combined router + Step 12: python -m pytest tests/phase_z2_ai_fallback/test_router.py tests/phase_z2_ai_fallback/test_step12.py -v -> 41 passed.
• Phase Z2 AI fallback regression: python -m pytest tests/phase_z2_ai_fallback/ -q -> 229 passed.

Scoped diff verification:

• git diff --stat -- src/phase_z2_ai_fallback/router.py src/phase_z2_ai_fallback/step12.py tests/phase_z2_ai_fallback/test_router.py tests/phase_z2_ai_fallback/test_step12.py -> 4 files changed, 197 insertions(+), 7 deletions(-).
• Scoped files match Stage 2 implementation units: router.py, step12.py, test_router.py, test_step12.py.
• Working tree also contains unrelated local changes/untracked files, including .claude/settings.json; these are outside commit scope and were not evaluated as IMP-46 changes.

Verified implementation facts:

• src/phase_z2_ai_fallback/router.py:53 adds optional fingerprints: dict | None = None.
• src/phase_z2_ai_fallback/router.py:72 forwards read_proposal(cache_key, fingerprints=fingerprints).
• src/phase_z2_ai_fallback/step12.py:203 forwards the already-built local fingerprints dict into route_ai_fallback(...).
• tests/phase_z2_ai_fallback/test_router.py:109-187 contains the three router-level u2 scenarios: mismatch miss, matching hit, and legacy fingerprints=None.
• tests/phase_z2_ai_fallback/test_step12.py:517-604 contains the five u4 integration tests proving AI-eligible forwarding and skipped/non-AI no-router behavior.
• git diff -- src/phase_z2_ai_fallback/cache.py src/phase_z2_ai_fallback/signature.py is empty; protected cache backend/signature territory remains untouched.
• git diff -- src/phase_z2_ai_fallback/step12.py shows only the fingerprints=fingerprints forward in production Step 12; save-side cache persistence was not changed.

[Claude #1] Stage 5 commit-push — IMP-46 (#62) Axis R u1~u4

📌 Stage 5: 커밋 및 푸쉬 완료

■ 핵심 결정

• IMP-46 (#62) Axis R u1~u4 commit d9d3384 작성, path-scoped staging 으로 4 파일만 포함.
• origin (GitHub) + slide2 (Gitea mirror) 양측 push 성공. 두 remote 모두 d9d3384 정합.
• Stage 4 plan 과 1:1 매칭: 197+/7- 변경, production 13 lines (router.py +6/-1, step12.py +1/-0), test 195 lines.
• git add -A 사용 금지 준수. .claude/settings.json 외 unrelated untracked 모두 unstaged 유지.
• IMP-47B (#76) carve-out 영역 (cache.py, signature.py) diff = empty. 침범 없음.

■ 범위 제외

• IMP-46 와 무관한 working tree 변경 (.claude/settings.json, tests/matching/, Front/, samples/, untracked tmp*.json 등) 전부 unstaged.
• cache.py / signature.py 변경 없음.
• u5+ 후속 axis — 본 이슈 범위 밖.

■ 다음 단계

• Stage 6 (final-close) 진입 대기.

[Codex #1] Stage 5 commit-push verification -- IMP-46 (#62)

Stage 5 verification result: PASS.

I verified the commit and both pushed remotes from git state, without reading Gitea comments.

Commit verified:

• HEAD = d9d338416a
• origin/main = d9d338416a
• slide2/main = d9d338416a
• all_equal = true

Unintended-file check:

• Commit name-only list is exactly the four scoped files above.
• Current working tree still contains unrelated modified/untracked files, but they are not in commit d9d3384.
• Protected carve-out files have no diff in the commit: src/phase_z2_ai_fallback/cache.py and src/phase_z2_ai_fallback/signature.py.

Remote target check:

• origin: git@github.com:keimin86/design_agent.git
• slide2: https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2.git
• gitea remote exists but points to https://gitea.hmac.kr/Kyeongmin/_Geulbeot.git, so skipping it is consistent with the reported different-project guardrail.

[Claude #1] Stage 6 final-close — IMP-46 (#62)

📌 Issue re-read vs commit on origin

Issue scope (body)	Status
AI 호출 직전/직후 cache lookup/save layer	absorbed by IMP-47B (#76) 1186ad8
data/frame_cache/{frame_id}/{signature_hash}.json path format	absorbed by #76
8-axis signature (frame_id + v4_label + cardinality + source_shape + h3 + 글자수 bucket + layout preset + zone position)	absorbed by #76
Save gate: visual_check PASS + 사용자 OK / --auto-cache	absorbed by #76
Invalidation: contract / partial / catalog SHA 변경 시 폐기	cache-side absorbed by #76 (strict equality at cache.py:108-148); router read-path enforcement gap = residual Axis R

Stage 1 carved the residual into Axis R (router read-path fingerprint forwarding). Stages 2–5 executed u1~u4 against that carve-out only — IMP-47B (#76) cache.py / signature.py territory untouched.

Carve-out diff in d9d3384 for src/phase_z2_ai_fallback/cache.py and src/phase_z2_ai_fallback/signature.py = empty. IMP-47B (#76) 1186ad8 territory untouched.

📌 Goal vs result

• Goal (issue body): cache layer 가 strict invalidation 능력을 갖되, contract/partial/catalog SHA 변경 시 폐기가 end-to-end 로 작동.
• Residual gap (Stage 1): cache.py 자체는 strict 했지만 router (route_ai_fallback) 가 fingerprints 인자를 받지 않아 step12 producer 가 만든 SHA 3종이 read-path 까지 도달하지 못함 → stale entry 위험.
• Result (u1~u4): router 가 fingerprints: dict | None = None kwarg 을 노출하고 read_proposal(cache_key, fingerprints=fingerprints) 로 그대로 흘려보냄. step12 는 이미 보유한 record["fingerprints"] 를 동일 객체로 전달. router-level 3 시나리오 (mismatch-miss / match-hit / legacy-None) + step12 integration 5 시나리오 (AI-eligible forwarding, default-catalog kwarg presence, non-provisional no-router, skipped/non-AI 변형) 로 invariant lock.
• 결정론적 hit 보장: 같은 input → 같은 output (cache.py 의 strict equality + 새로 닫힌 router read-path).

📌 Scope-qualified verification

python -m pytest tests/phase_z2_ai_fallback/test_router.py tests/phase_z2_ai_fallback/test_step12.py -q
  → 41 passed in 0.09s
python -m pytest tests/phase_z2_ai_fallback/ -q   (Stage 4)
  → 229 passed in 0.44s (regression clean)

Out-of-scope (declared):

• .env-driven baseline reds (4 건) — axis-orthogonal, 별도 evidence-based 이슈 후보.
• tests/conftest.py AI_FALLBACK_ENABLED scrubber (구 u5) — Stage 1 allowed_edits 밖, separate axis.
• 운영 단계 cache → catalog promotion (R4 backlog).

📌 Follow-up links

• pair: IMP-33 (#?) — AI 호출 실선; 본 cache layer 가 그 결과를 결정론적으로 재사용함.
• consumer: 모든 IMP-33 호출 시점 (자동 lookup).
• backlog: cache → catalog promote 기능 (R4).
• separate follow-up candidates (이번 이슈에서 분리 처리):
  • .env-driven 4 baseline-red root cause
  • tests/conftest.py AI_FALLBACK_ENABLED scrubber

📌 Labels / Close decision

• 권장 labels: IMP-46, R3, wave-1, done (또는 프로젝트 컨벤션 매핑).
• review loop 체크리스트: Codex 1차 review / Claude 재검토 / Codex 재검증 / scope-locked / ready-for-implementation / implemented / verified — Stage 1~5 exit reports 가 모두 충족.

Close decision: CLOSE (resolved)

Rationale:

1. Commit d9d3384 exists on both origin (GitHub) and slide2 (Gitea mirror), heads identical.
2. Diff matches Stage 2 plan exactly (197+/7-, production 13 lines, plan_match: exact).
3. Carve-out (IMP-47B #76 1186ad8 cache territory) untouched.
4. All scope-qualified tests green (41/41 router+step12; 229/229 phase_z2_ai_fallback regression).
5. Residual Axis R (router read-path fingerprint enforcement) — the only gap left after #76 absorption — is closed.

=== EVIDENCE ===

• git rev-parse HEAD origin/main slide2/main → all d9d338416ab277f55deaf8496f827cd17260cb87
• git show --stat d9d3384 → 4 files, 197+/7-, matches Stage 4/5 plan
• git diff d9d3384^ d9d3384 -- src/phase_z2_ai_fallback/cache.py src/phase_z2_ai_fallback/signature.py → empty (carve-out untouched)
• python -m pytest tests/phase_z2_ai_fallback/test_router.py tests/phase_z2_ai_fallback/test_step12.py -q → 41 passed in 0.09s
• Issue body §scope vs commit content: cache backend / signature / save-side absorbed by #76, residual Axis R closed by u1~u4 here.
• source_comment_ids: Stage 1 [Claude #1]+[Codex #1], Stage 2 [Claude #4]+[Codex #4], Stage 3 [Claude #4]+[Codex #4], Stage 4 [Claude #1]+[Codex #1], Stage 5 [Claude #1]+[Codex #1] all binding-contract exit reports.

Residual Axis R (router read-path fingerprint enforcement) — the only gap left after #76 absorption — is closed. === EVIDENCE === - `git rev-parse HEAD origin/main slide2/main` → all `d9d338416ab277f55deaf8496f827cd17260cb87` - `git show --stat d9d3384` → 4 files, 197+/7-, matches Stage 4/5 plan - `git diff d9d3384^ d9d3384 -- src/phase_z2_ai_fallback/cache.py src/phase_z2_ai_fallback/signature.py` → empty (carve-out untouched) - `python -m pytest tests/phase_z2_ai_fallback/test_router.py tests/phase_z2_ai_fallback/test_step12.py -q` → 41 passed in 0.09s - Issue body §scope vs commit content: cache backend / signature / save-side absorbed by #76, residual Axis R closed by u1~u4 here. - source_comment_ids: Stage 1 [Claude #1]+[Codex #1], Stage 2 [Claude #4]+[Codex #4], Stage 3 [Claude #4]+[Codex #4], Stage 4 [Claude #1]+[Codex #1], Stage 5 [Claude #1]+[Codex #1] all binding-contract exit reports.

[Codex #1] Stage 6 final-close verify -- IMP-46 (#62)

Verdict: PASS. I independently verified the pushed commit, scoped diff, protected carve-out, and current router/step12 regression surface for the residual Axis R fix.

Issue reread vs implemented scope:

• The broad IMP-46 cache backend/signature/save-gate work is treated as absorbed by IMP-47B (#76) commit 1186ad8, per the binding exit reports.
• The remaining Stage 1 root cause was the router read-path fingerprint enforcement gap: step12.py produced contract/partial/catalog fingerprints, but route_ai_fallback did not forward them into read_proposal.
• Commit d9d3384 addresses that residual scope only: router accepts optional fingerprints, forwards it to cache read, and Step 12 passes the record fingerprints on AI-eligible routes.

Verified commit state:

• HEAD, origin/main, and slide2/main all resolve to d9d338416ab277f55deaf8496f827cd17260cb87.
• Commit message is feat(#62): IMP-46 cache fingerprint forwarding u1~u4 (router kwarg + step12 forward + 8 scenarios).
• Commit file scope is exactly four files: src/phase_z2_ai_fallback/router.py, src/phase_z2_ai_fallback/step12.py, tests/phase_z2_ai_fallback/test_router.py, and tests/phase_z2_ai_fallback/test_step12.py.
• Commit shortstat is 4 files changed, 197 insertions(+), 7 deletions(-).
• Minor correction to prior per-file attribution: git diff --numstat reports router.py +7/-1, step12.py +1/-0, test_router.py +87/-6, test_step12.py +102/-0. The total and four-file scope remain as reported.
• src/phase_z2_ai_fallback/cache.py and src/phase_z2_ai_fallback/signature.py have no diff in d9d3384, so the IMP-47B carve-out remains untouched.
• The unrelated dirty/untracked working-tree artifacts shown by git status --short are not in the commit.

Verified behavior:

• src/phase_z2_ai_fallback/router.py:53 defines fingerprints: dict | None = None.
• src/phase_z2_ai_fallback/router.py:72 calls read_proposal(cache_key, fingerprints=fingerprints).
• src/phase_z2_ai_fallback/step12.py:179-185 builds the fingerprint dict and stores it on record["fingerprints"].
• src/phase_z2_ai_fallback/step12.py:195-203 forwards fingerprints=fingerprints into route_ai_fallback.
• Router-level tests cover mismatch miss, matching hit, and legacy None behavior at tests/phase_z2_ai_fallback/test_router.py:109-187.
• Step 12 integration tests cover AI-eligible exact forwarding and skipped/non-AI no-router behavior at tests/phase_z2_ai_fallback/test_step12.py:517-604.
• Current targeted regression is green: 41 passed in 0.09s.

• HEAD == origin/main == slide2/main == d9d338416ab277f55deaf8496f827cd17260cb87.
• Commit scope is exactly the four approved files; no cache.py or signature.py diff exists in the commit.
• The router read path is now fingerprint-aware while legacy callers still default to fingerprints=None.
• Step 12 forwards its produced fingerprint dict to the router for AI-eligible units.
• Router and Step 12 targeted tests pass: 41 passed in 0.09s.
