Other Step 16 router action labels are MISSING.\n- Backlog §2 `IMP-12` + INSIGHT-MAP §3 axis registry propose three Salvage Candidates: `redistribute` + glue + font compression (sourced from PHASE-Q-AUDIT §2.4 / §2.5).\n\n**Current code paths (verified)**\n- Router: `src/phase_z2_router.py:28-37` `ACTION_BY_CATEGORY` — 8-category mapping. `zone_ratio_retry` is the only IMPLEMENTED entry; `layout_adjust` / `details_popup_escalation` MISSING, `frame_reselect` / `adapter_needed` PARTIAL, `abort` IMPLEMENTED.\n- Retry plan: `src/phase_z2_retry.py:43-195` `plan_zone_ratio_retry` — **single primary donor only**. Lines 165-180: `if primary_donor[\"slack\"] < target_added_px → feasible=False`, with inline comment \"A3 minimal : single primary donor (multi-donor 는 future)\".\n- Retry orchestrator: `src/phase_z2_pipeline.py:1765-1900` `_attempt_zone_ratio_retry` — retry_budget=1, donor rule strict (sibling / visual ok / capacity ok / slack>0 / min_height preserved, line 1813).\n- Failure router: `src/phase_z2_failure_router.py` — `donor_slack_insufficient` enum exists, consumed downstream.\n- Salvage sources: `src/fit_verifier.py:488-587` `ROLE_ZONE_MAP` + `redistribute(analysis, containers, min_margin_px)` (role/zone schema, Phase Q product). `src/space_allocator.py:897-1011` `GlueSpec / SPACING_GLUE / FONT_SIZE_STEPS / compute_glue_css_overrides / find_fitting_font_size`.\n\n**Upstream locks that constrain Step 16/17 scope**\n\n1. **PHASE-Z-PIPELINE-OVERVIEW.md:333 Step 17 user lock (current)** : \"frame_internal_fit_candidate 가 *허용할 수 있는 내부 sub-mechanism* (density envelope / line rhythm / internal grid row / text block allocation 등) 은 *frame contract 가 declare 한 envelope 안* 에서만 동작 ... **별도 action label 로 등재하지 않음** — `density_adjust_candidate` 같은 이름은 *공통 CSS/padding 축소 antipattern* 을 초대할 위험\". Verbatim Korean quote from doc.\n2. **memory `feedback_phase_z_spacing_direction`** : forbids \"shared text-line gap\", \"transform-block padding\", \"section-title margin-bottom\" shrinking. Direction is preserve / increase breathing room, not shrink to fit.\n3. **PHASE-Z-PIPELINE-OVERVIEW.md:352 Step 19** : `frame_internal_fit_candidate` execution contract / internal envelope **undefined** (the frame-contract envelope format itself is yet to be specified).\n4. **PHASE-Q-AUDIT.md:1300** — the source already classifies the three Salvage Candidates as `§3 review subjects`, not as automatic adoption. AI-isolation invariant + \"audit verdict ≠ adoption decision\" reaffirmed in the 2026-05-11 reclassification pass.\n\n**Root cause + conflict**\n- Primary root cause = `plan_zone_ratio_retry` is single-donor only. When the primary donor's slack is insufficient, sibling donors could supply additional slack but the planner returns feasible=False.\n- Secondary observation = the source §2.5 glue + font compression are exactly the antipattern that lock #1 and memory rule #2 forbid: `compute_glue_css_overrides` shrinks the shared CSS vars `--spacing-block` / `--spacing-inner` / `--container-padding` (`space_allocator.py:944-983`), and `find_fitting_font_size` shrinks the visible font size globally (`space_allocator.py:986-1011`). Lock #3 means the frame-contract envelope that could legitimately host them does not exist yet.\n\n**Key conclusion** : Of the three Salvage Candidates, only zone-level multi-donor `redistribute` is compatible with the active locks. Glue + font compression conflict directly with the locks → explicit reject from IMP-12 scope.\n\n## Scope-lock (2 axes, refine-only)\n\n### IN scope\n\n1. **axis_1 — multi-donor aggregation** : Extend `src/phase_z2_retry.py:165-180` `plan_zone_ratio_retry` from the single-donor branch to aggregated multi-donor.\n - When the primary donor is insufficient, walk the already-sorted `donor_candidates` (slack desc) and accumulate reductions.\n - Each donor's contribution = `min(remaining_target, donor.slack)` — each donor's `min_height_px` floor is preserved (existing rule 4-d kept intact).\n - Sum ≥ `target_added_px` → `feasible=True`. Sum < `target_added_px` → `feasible=False` with combined-slack trace.\n - `zones_after` reflects every donor's reduction.\n\n2. **axis_2 — trace fidelity** : Add `donors_applied: [{position, reduced_px}]` list to the retry plan output.\n - Existing scalar fields `donor_zone_position` / `donor_reduced_px` retained for back-compat (populated from the single-donor case or from the primary entry in the list). Existing pipeline / failure_router consumers see no regression.\n - For `feasible=False`, `failure_reason` cites both *combined slack* and *target_added_px*, and records the candidate-list length.\n - Downstream `_attempt_zone_ratio_retry` (`src/phase_z2_pipeline.py:1886`) log line assumes a single donor. Plumbing change is optional (back-compat allows skip); Stage 2 decides.\n\n### OUT of scope (explicit reject)\n\n- **`glue_compression` router action label** — shrinks shared CSS variables. Violates Step 17 user lock + `feedback_phase_z_spacing_direction`. Reject.\n- **`font_size_retry` router action label** — shrinks shared font size. Same lock + memory-rule violations. Reject.\n- **`ACTION_BY_CATEGORY` mapping extension** — router table unchanged. Only `zone_ratio_retry` internals are refined; no new categories or actions.\n- **AI / Kei retry loop (H5) revival** — guardrailed by issue body.\n- **Cross-layout / cross-zone-position transfer** — donor rule 4-a (same-layout siblings) unchanged.\n- **Retry budget increase** — stays 1 (rule 1).\n- **`slide / slide-body / title / divider / footer / zone gap`** — fixed (rule 2).\n- **Catalog (`frame_contracts.yaml`) modification** — read-only reference, no writes.\n\n### Future-axis recording (separate issues, outside IMP-12)\n\nIf glue / font compression are ever to land, they belong inside `frame_internal_fit_candidate` (Step 19, currently undefined envelope). That would require: (1) a new frame-contract `density_envelope` field (Step 10 contract extension), (2) per-frame opt-in declarations, (3) execution scope strictly inside the declaring frame's DOM subtree — never shared CSS vars. None of that is in IMP-12.\n\n## Guardrails\n\n- AI fallback X (`feedback_ai_isolation_contract`).\n- Kei retry loop (H5) X (issue body guardrail).\n- Status semantics consistent — when retry is infeasible, `RENDERED_WITH_VISUAL_REGRESSION` is preserved (issue body).\n- No shared CSS / font / padding shrink (Step 17 user lock + `feedback_phase_z_spacing_direction`).\n- No new router action labels (Step 17 user lock).\n- Each donor's `min_height_px` floor preserved (existing rule 4-d).\n- Retry budget = 1 (existing rule 1).\n- Catalog SHA unchanged.\n- Zero collision with `IMP-05` — IMP-05 touches the router `ACTION_BY_CATEGORY` / V4 fallback action surface; IMP-12 touches `plan_zone_ratio_retry` internals + trace plumbing only.\n\n## Validation (3-axis status)\n\n- **rendered** : `pytest -q tests/phase_z2/test_retry_gate.py` regression 0 (single-donor early-exit paths unchanged). New unit-test file decided in Stage 2.\n- **visual_check** : MDX 03 / 04 / 05 single-donor cases unchanged. Identify at least one case where multi-donor newly becomes feasible (Stage 2 names the sample).\n- **full_mdx_coverage** : This axis refines the retry path. Coverage is orthogonal.\n\n### Tests (Stage 2 will finalize)\n\n- New unit test (e.g. `tests/phase_z2/test_zone_ratio_retry_plan.py`):\n - Direct calls to `plan_zone_ratio_retry`.\n - Case A: single donor sufficient → legacy behavior (output identical).\n - Case B: primary < target, primary + secondary ≥ target → `feasible=True`, `donors_applied` length 2, sum(reductions) == `target_added_px`, each donor's `min_height_px` floor verified.\n - Case C: all donors combined < target → `feasible=False`, `failure_reason` cites combined slack + target.\n - Case D: zero donors → existing `no donor candidates` failure (unchanged).\n- Existing `tests/phase_z2/test_retry_gate.py` PASS preserved.\n\n## Dependency\n\n- `soft link: IMP-05` (Step 16 router scope shared, parallel allowed) — IMP-05 extends `ACTION_BY_CATEGORY` / V4 fallback action; IMP-12 refines `plan_zone_ratio_retry` internals + trace. **No table collision.** Parallel OK.\n\n## Open questions for next reviewer (Codex #1)\n\n**Q1** — Do you concur with rejecting glue + font compression from IMP-12 scope?\n- Basis = Step 17 user lock (line 333) forbidding `density_adjust_candidate`-style labels + `feedback_phase_z_spacing_direction` forbidding shared spacing shrink + Step 19 `frame_internal_fit_candidate` envelope undefined.\n- If concur → scope-lock stands as drafted (axis_1 + axis_2). If not → user-lock-lift request + scope expansion goes to a separate stage.\n\n**Q2** — `donors_applied` list addition: keep legacy scalar `donor_zone_position` / `donor_reduced_px` for back-compat, or drop them in favor of list only?\n- This draft = back-compat preserved (downstream log + failure_router enum reference unchanged). Drop is feasible (only one call site: `phase_z2_pipeline.py:1886`).\n\n## Cross-ref (factual, file:line)\n\n- Router table: `src/phase_z2_router.py:28-37` (ACTION_BY_CATEGORY) + `:61-68` (ACTION_IMPLEMENTATION_STATUS).\n- Retry plan: `src/phase_z2_retry.py:43-195` (single-donor branch 165-180).\n- Retry orchestrator: `src/phase_z2_pipeline.py:1765-1900` (log line 1886).\n- Failure router: `src/phase_z2_failure_router.py` (`donor_slack_insufficient` reference).\n- Step 17 user lock: `docs/architecture/PHASE-Z-PIPELINE-OVERVIEW.md:333`.\n- Step 19 envelope undefined: `docs/architecture/PHASE-Z-PIPELINE-OVERVIEW.md:352`.\n- Memory rule: `memory/feedback_phase_z_spacing_direction.md` (entire body).\n- Salvage source 1: `src/fit_verifier.py:488-587` (redistribute pattern, role/zone schema).\n- Salvage source 2: `src/space_allocator.py:897-1011` (GlueSpec / FONT_SIZE_STEPS / compute_glue_css_overrides / find_fitting_font_size).\n- Audit classification: `docs/architecture/PHASE-Q-AUDIT.md:454,468,476,489-493,548-549,565-569,576` (Salvage Candidate categorization + dual-write review criteria).\n- Backlog definition: `docs/architecture/PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md:63` (IMP-12 row).\n- INSIGHT-MAP §3 registry: `docs/architecture/PHASE-Q-INSIGHT-TO-22STEP-MAP.md:118` (Step 16/17 retry refinement axis).\n\n## Stage 2 plan input\n\n- 2 changed files:\n 1. `src/phase_z2_retry.py` (lines 142-195 region — base_plan construction + multi-donor aggregation branch + zones_after computation).\n 2. `src/phase_z2_pipeline.py:1886` (optional — donor log line plumbing; can be skipped if back-compat retains scalar fields).\n- 1 new test file:\n - `tests/phase_z2/test_zone_ratio_retry_plan.py` (4 unit test cases).\n- Stage 4 verify scope: existing `tests/phase_z2/test_retry_gate.py` + new unit tests PASS, and MDX 03 / 04 / 05 baseline regression-free.\n\n=== EVIDENCE ===\n\nCommands run :\n- `Read src/phase_z2_router.py` (entire file, 1-181) — confirmed router action mapping + ACTION_IMPLEMENTATION_STATUS.\n- `Read src/phase_z2_retry.py` (entire file, 1-215) — confirmed single-donor branch location + retry rules.\n- `Grep _attempt_zone_ratio_retry|donor src/phase_z2_pipeline.py` → orchestrator at lines 1765-1900, log line at 1886.\n- `Read docs/architecture/PHASE-Z-PIPELINE-OVERVIEW.md` (Step 14-22, lines 298-403) — confirmed Step 17 user lock + Step 19 envelope-undefined notes.\n- `Read docs/architecture/PHASE-Z-FIT-CLASSIFIER-ROUTER-SPEC.md` (§4 + §5 + §7 + §8) — action mapping table + current implementation gap.\n- `Read docs/architecture/PHASE-Q-AUDIT.md:410-579` — §2.4 V-3 redistribute + §2.5 glue + font compression classification (all Salvage Candidates, §3 review subjects).\n- `Read docs/architecture/PHASE-Q-INSIGHT-TO-22STEP-MAP.md:100-150` — §3 axis registry line 118 (Step 16/17 retry refinement sourced from §2.4 + §2.5).\n- `Grep IMP-12 docs/architecture/PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md` → backlog entry at line 63.\n- `Read src/fit_verifier.py:488-587` — confirmed `ROLE_ZONE_MAP` + `redistribute` zone-internal role-to-role px transfer pattern.\n- `Read src/space_allocator.py:897-1011` — confirmed `GlueSpec / SPACING_GLUE / FONT_SIZE_STEPS / compute_glue_css_overrides / find_fitting_font_size`; the glue overrides target shared CSS vars `--spacing-block` / `--spacing-inner` / `--container-padding`.\n- `Read memory/feedback_phase_z_spacing_direction.md` (entire) — confirmed forbidden expressions (\"shared text-line gap / transform-block padding / section-title margin-bottom 줄이자\") + allowed-layer 5-step ladder.\n- `Grep plan_zone_ratio_retry|zone_ratio_retry tests/` → `tests/phase_z2/test_retry_gate.py` covers only single-donor + early-exit paths; multi-donor unit tests absent.\n\nFacts established :\n1. `plan_zone_ratio_retry` is single-donor only — multi-donor aggregation is explicitly flagged as \"future\" (`phase_z2_retry.py:178-179`).\n2. `compute_glue_css_overrides` shrinks shared CSS variables — same pattern as the `density_adjust_candidate` antipattern forbidden by Step 17 user lock.\n3. `find_fitting_font_size` shrinks shared font size — not mappable to any of the 5 allowed layers in `feedback_phase_z_spacing_direction`.\n4. Step 19 `frame_internal_fit_candidate` envelope is undefined — no contract container exists for glue / font compression to live inside.\n5. Router `ACTION_BY_CATEGORY` is a closed mapping — registering a new action label would violate Step 17 user lock.\n6. `tests/phase_z2/test_retry_gate.py` does not cover the multi-donor case — new test required.\n7. `IMP-05` works on the router table / V4 fallback surface; `IMP-12` works inside the retry plan — no table collision, parallel execution OK.\n\nUnknown surface (Stage 2 plan will resolve) :\n- `_attempt_zone_ratio_retry` (`phase_z2_pipeline.py:1886`) donor log line plumbing: skip vs. extend to list — back-compat allows skip; Stage 2 to decide.\n- Exact fixture numerics for the new tests (zone min_heights / observed excess_y) — Stage 2 plan finalizes.\n- Multi-donor aggregation reduction policy: greedy fill (slack-desc order) vs. proportional (per-donor slack share).

Repository evidence does support the broader lock: `docs/architecture/PHASE-Z-PIPELINE-OVERVIEW.md:110-114` says common CSS/padding/tolerance shrinking is not a graph change and is forbidden; `docs/architecture/PHASE-Z-PIPELINE-OVERVIEW.md:420-428` cross-references `feedback_phase_z_spacing_direction` for Step 17 common spacing changes.\n- Therefore Stage 2 should not assume glue/font compression can be adopted blindly. It must define deterministic action labels and status semantics while respecting the no-silent-shrink / no-common-padding-shrink lock, or explicitly exclude unsafe submechanisms.\n\nMissing files / wrong assumptions flagged:\n- No required source/doc file from the issue references was missing.\n- Wrong assumption to avoid: treating Phase Q glue/font helpers as automatic Step 17 fixes.

Cascade is driven by\n `phase_z2_failure_router.NEXT_ACTION_BY_FAILURE` chain, NOT by composite call.\n Rationale: independent feasibility + revert + diagnostic artifact per step; matches existing\n `(b) revert` policy; observable trace per action.\n\n- **Q3 — glue / font output target: CSS-time vs adapter?**\n → **Frame-scoped CSS override at rerender time** (NEW helper emits\n `.slide [data-zone-position=\"<pos>\"] { --spacing-inner: ...; --container-padding: ...; font-size: ...; }`).\n NEVER touches global `--spacing-block` / `--spacing-page`.\n Rationale: honors `feedback_phase_z_spacing_direction` (\"resolve within frame envelope, not by\n common shrink\") + Stage-1 upstream lock `PHASE-Z-PIPELINE-OVERVIEW.md:333`.\n\n## Per-axis: expected behavior, files, changes, tests, rollback, side effects\n\n### A1 — multi-donor `zone_ratio_retry`\n\n- **Before**: `src/phase_z2_retry.py:163-180` — only `donor_candidates[0]` evaluated;\n if `primary_donor.slack < target_added_px` → `feasible=False` + reason\n `\"primary donor ... slack ... < target_added_px ...\"`.\n- **After**: greedy aggregation across `donor_candidates` (already sorted by slack desc).\n Each donor contributes up to its slack; loop stops when remaining_needed ≤ 0 OR donor list\n exhausted. `feasible=True` iff aggregate slack ≥ target_added_px. On failure, new reason\n `\"aggregate donor slack <sum>px across N donors < target_added_px <T>px\"` →\n classifier maps to existing `donor_slack_insufficient`.\n- **Files**: `src/phase_z2_retry.py` (function body), plus the `zones_after` math (loop\n reducing each donor by its share).\n- **Per-file change**: extend lines 165-195 — replace single-donor block with multi-donor\n loop; preserve all existing return fields; add new fields `donors_used: list[dict]`,\n `aggregate_slack_used: int`. `apply_retry_to_layout_css` already consumes\n `plan[\"zones_after\"]` (dict) so it handles multi-donor with no change.\n- **Tests**: `tests/phase_z2/test_phase_z2_retry_multi_donor.py` — single-donor sufficient\n (regression), single-donor insufficient + 2nd donor sufficient (multi-donor PASS),\n all donors aggregate still < target (multi-donor FAIL with new reason).\n- **Rollback**: revert single commit. `zones_after` semantics unchanged → downstream\n `apply_retry_to_layout_css` keeps working.\n- **Side effects**: `retry_trace.plan` grows by 2 fields. Step 17 JSON artifact grows\n ~50 bytes. No effect on slide_status.\n\n### A2 — `cross_zone_redistribute` (new salvage action #1)\n\n- **Before**: `fit_verifier.redistribute(analysis, containers)` already redistributes\n within-zone roles (e.g., `body` zone has roles 본심+배경; surplus role donates to\n deficit role until `min_margin_px`). Used in `pipeline.py` legacy path only; NOT wired\n into Step 17.\n- **After**: NEW `plan_cross_zone_redistribute(...)` in `src/phase_z2_retry.py` —\n wraps `fit_verifier.redistribute` with a Step-17 plan-style signature. Input:\n target frame's role-level analysis from `composition` artifact; output: per-role\n `allocated_px` override dict, feasible flag, failure reason. On feasible, the apply\n function emits frame-scoped CSS:\n `.slide [data-zone-position=\"<pos>\"] [data-role=\"본심\"] { height: <Apx>; } [data-role=\"배경\"] { height: <Bpx>; }`\n (or equivalent grid-row-span override, whichever the existing frame template uses).\n- **Files**: `src/phase_z2_retry.py` (new function `plan_cross_zone_redistribute` +\n `apply_cross_zone_redistribute_css`).\n- **Per-file change**: ~50 lines: invoke `fit_verifier.redistribute(analysis, containers)`,\n inspect `analysis.can_redistribute`, build plan dict (feasible, role_heights_after,\n failure_reason). NO new logic — pure wiring.\n- **Tests**: `tests/phase_z2/test_phase_z2_cross_zone_redistribute.py` — body-zone with\n surplus 배경 + deficit 본심 → feasible=True with new heights; single-role zone →\n feasible=False reason `\"single-role zone — no intra-zone redistribution possible\"`.\n- **Rollback**: revert single commit. `fit_verifier.redistribute` untouched.\n- **Side effects**: `retry_trace.salvage_steps[]` grows by 1 entry per attempt.\n\n### A3 — `glue_compression` (new salvage action #2, frame-scoped)\n\n- **Before**: `space_allocator.compute_glue_css_overrides(excess_px, block_count)` returns\n `{\"--spacing-block\": \"Xpx\", \"--spacing-inner\": \"Ypx\", \"--container-padding\": \"Zpx\"}`.\n Currently unused in Phase Z runtime.\n- **After**: NEW `plan_glue_compression(...)` in `src/phase_z2_retry.py` — calls\n `compute_glue_css_overrides` on excess from `overflow.zones[target_zone].excess_y` and\n the frame's `block_count` (from `debug_zones[target].composition_rationale.frame_block_count`).\n Returns plan with `scoped_css_overrides: dict[str, str]`, `target_zone_position`,\n feasible (True if `excess_after_glue_px ≤ 0`), `failure_reason`. Apply helper emits\n ZONE-SCOPED block: `.slide [data-zone-position=\"<pos>\"] { --spacing-block: ...; ... }`.\n GLOBAL `--spacing-block` is NOT modified.\n- **Files**: `src/phase_z2_retry.py` (new function + apply helper).\n- **Per-file change**: ~45 lines.\n- **Tests**: `tests/phase_z2/test_phase_z2_glue_compression.py` — feasible case\n asserts (1) returned `scoped_css_overrides` non-empty (2) emitted CSS string is wrapped\n in `[data-zone-position=\"<pos>\"]` selector (3) NO global rule emitted (assert\n `body {` / `:root {` not in emitted CSS). Insufficient absorption case →\n feasible=False reason `\"glue absorption <max>px < excess <E>px (frame envelope)\"`.\n- **Rollback**: revert single commit. `compute_glue_css_overrides` untouched.\n- **Side effects**: rerender HTML grows by ~200 bytes when this action fires (a `<style>`\n block in slide-base header).\n\n### A4 — `font_step_compression` (new salvage action #3, frame-scoped)\n\n- **Before**: `space_allocator.find_fitting_font_size(current_font_px, excess_after_glue_px,\n available_lines, chars_per_line)` already returns the largest step in `FONT_SIZE_STEPS`\n that closes `excess_after_glue_px`. Unused in Phase Z runtime.\n- **After**: NEW `plan_font_step_compression(...)` in `src/phase_z2_retry.py`. Reads\n `current_font_px` from frame contract `style_tokens.text_size` (or fallback from\n `--font-body` token), `excess_after_glue_px` from `overflow` minus glue savings,\n `available_lines` from `debug_zones[target].composition_rationale.text_metrics.line_count`,\n `chars_per_line` from `text_metrics.chars_per_line`. Apply helper emits zone-scoped CSS\n `.slide [data-zone-position=\"<pos>\"] { font-size: <Xpx>; }`. feasible iff\n `find_fitting_font_size` returns non-None.\n- **Files**: `src/phase_z2_retry.py` (new function + apply helper).\n- **Per-file change**: ~40 lines.\n- **Tests**: `tests/phase_z2/test_phase_z2_font_step_compression.py` — feasible case\n (15.2→13.0 returns adequate height savings) and infeasible case (8px floor reached).\n- **Rollback**: revert single commit. `find_fitting_font_size` untouched.\n- **Side effects**: rerender HTML grows by ~80 bytes.\n\n### A5 — Step 16 router action surface (impl-status registration)\n\n- **Before**: `src/phase_z2_router.py:61-68` — `ACTION_IMPLEMENTATION_STATUS` has 6 keys\n (`zone_ratio_retry: IMPLEMENTED`, etc.).\n- **After**: ADD 3 new keys: `cross_zone_redistribute: IMPLEMENTED`,\n `glue_compression: IMPLEMENTED`, `font_step_compression: IMPLEMENTED`. NO new\n `ACTION_BY_CATEGORY` entries (Q1 lock — these are cascade-only, never primary).\n- **Files**: `src/phase_z2_router.py` (+ `src/phase_z2_failure_router.py` for\n `NEXT_ACTION_IMPLEMENTATION_STATUS` parity).\n- **Per-file change**: ~10 lines combined.\n- **Tests**: covered by u14 (cascade routing test asserts impl-status flips).\n- **Rollback**: revert keys. Router still emits routing decisions correctly even with\n status=`MISSING`.\n- **Side effects**: `step16_router_decision.json` shows new actions as IMPLEMENTED in\n `implementation_status_summary` ONLY when failure_router proposes them. No new\n entries appear on PASS path.\n\n### A6 — Step 17 cascade execution\n\n- **Before**: `src/phase_z2_pipeline.py:4295-4308` — single `_attempt_zone_ratio_retry`\n call writes one `retry_trace`. Step 17 telemetry at 4329-4342.\n- **After**: After `_attempt_zone_ratio_retry` returns with `retry_passed=False` AND\n `failure_classification.failure_type ∈ {donor_slack_insufficient, no_donor_candidates}`,\n invoke NEW `_attempt_salvage_chain(...)` which iterates failure_router's\n `next_proposed_action` in order: `cross_zone_redistribute` → `glue_compression` →\n `font_step_compression`. Each iteration: plan → apply → rerender to a NEW candidate\n HTML (`salvage_<action>_candidate.html`) → `run_overflow_check` → on PASS promote to\n `final.html` AND set `retry_trace.salvage_passed = True`. On all FAIL, original\n `final.html` stays (b-revert policy preserved). Step 17 telemetry surface grows with\n `retry_trace.salvage_steps: list[step_trace]` and `retry_trace.salvage_passed: bool`.\n- **Files**: `src/phase_z2_pipeline.py` (new `_attempt_salvage_chain` function + wiring\n block).\n- **Per-file change**: u8 (~50 lines, `_attempt_salvage_chain` skeleton), u9 (~30 lines,\n pipeline wiring + telemetry block update at 4329-4342).\n- **Tests**: u15 — fixtures simulate (a) `_attempt_zone_ratio_retry` fails with\n donor_slack_insufficient + cross_zone_redistribute succeeds → final.html promoted +\n salvage_steps=1 entry passed (b) cross_zone fails + glue succeeds → salvage_steps=2,\n second passed (c) all 3 fail → salvage_passed=False, final.html unchanged.\n- **Rollback**: revert wiring unit (u9). `_attempt_salvage_chain` becomes dead code.\n Single-commit revert returns to pre-IMP-12 Step 17 behavior.\n- **Side effects**: `run_dir/` directory grows by up to 3 `salvage_*_candidate.html`\n diagnostic artifacts when salvage fires. No effect on PASS path.\n\n### A7 — failure_router cascade rewire\n\n- **Before**: `src/phase_z2_failure_router.py:61-65` —\n - `donor_slack_insufficient` → `layout_adjust`\n - `no_donor_candidates` → `layout_adjust`\n - `rerender_still_fails` → `frame_reselect`\n- **After**:\n - `donor_slack_insufficient` → `cross_zone_redistribute` (was `layout_adjust`)\n - `no_donor_candidates` → `cross_zone_redistribute` (was `layout_adjust`)\n - NEW `cross_zone_redistribute_insufficient` → `glue_compression`\n - NEW `glue_absorption_insufficient` → `font_step_compression`\n - NEW `font_step_insufficient` → `layout_adjust` (escalate out of salvage cascade)\n - `rerender_still_fails` → `frame_reselect` (unchanged)\n - `not_attempted` → `none` (unchanged)\n- Classifier (`classify_retry_failure`) must also surface the 3 new failure types from\n `retry_trace.salvage_steps[last].failure_reason` text matching, in the same idiom as\n current donor_slack_insufficient classification.\n- **Files**: `src/phase_z2_failure_router.py`.\n- **Per-file change**: u2 (~30 lines — `FAILURE_TYPE_DESCRIPTIONS` adds 3, classifier\n adds 3 case branches reading from `retry_trace.salvage_steps`), u3 (~25 lines —\n `NEXT_ACTION_BY_FAILURE` + `NEXT_ACTION_RATIONALE` add 3 entries; mutate\n `donor_slack_insufficient` / `no_donor_candidates` targets).\n- **Tests**: u14 — for each new failure type, assert `route_retry_failure` returns the\n correct cascade target with `implementation_status=\"IMPLEMENTED\"`.\n- **Rollback**: revert u2 + u3. Restores layout_adjust mapping. `_attempt_salvage_chain`\n in u9 still callable but never invoked since failure_router never points there.\n- **Side effects**: documentation table comment block at top of\n `phase_z2_failure_router.py` must reflect new mapping; otherwise none.\n\n## Cross-axis invariants (Stage-1 binding contracts verified)\n\n- **No AI on normal path** (`feedback_ai_isolation_contract`): every new function is\n deterministic. No `anthropic` / `kei` import touched. CI grep check covers this.\n- **No common-margin shrink** (`feedback_phase_z_spacing_direction`): glue/font CSS\n is ALWAYS wrapped in `[data-zone-position=\"<pos>\"]` selector. u12 test asserts\n emitted CSS contains NO `:root {` / `body {` / `.slide {` (unscoped) rules.\n- **No new density-style labels** (`PHASE-Z-PIPELINE-OVERVIEW.md:333` lock): action\n names are `cross_zone_redistribute`, `glue_compression`, `font_step_compression` —\n spec-aligned salvage names; not `density_adjust_candidate` etc.\n- **Status semantics** (`feedback_artifact_status_naming`): `slide_status.overall`\n becomes `PASS` only if `retry_passed=True` OR `salvage_passed=True` (no overflow on\n final). Otherwise stays `RENDERED_WITH_VISUAL_REGRESSION`. u15 asserts.\n- **Kei retry H5 non-regression**: no edit to `_attempt_zone_ratio_retry` body beyond\n multi-donor extension; cascade is added AFTER it, not replacing it.\n\n## Risk + follow-up issue candidates\n\n- **R1 — `composition_rationale.frame_block_count` may be absent for some frames.**\n Mitigation: u5 reads with `.get(\"frame_block_count\", 1)` default. Follow-up issue\n candidate: backfill `frame_block_count` on all 32 frames (separate axis).\n- **R2 — `text_metrics.line_count` / `chars_per_line` may not exist on all units.**\n Mitigation: u6 reads with sensible defaults from frame contract; on missing keys,\n returns `feasible=False` reason `\"text_metrics missing — cannot evaluate font step\"`.\n Follow-up: ensure composition emits text_metrics in `comp_debug` (separate axis).\n- **R3 — Salvage chain interacts with IMP-09 retry gate.** `_attempt_salvage_chain`\n must respect the same `dynamic_cols` / `fr_default` gate — verified by adding the\n gate check at the top of `_attempt_salvage_chain` (u8).\n- **R4 — `frame_reselect` cascade entry remains MISSING** (Stage-1 out-of-scope).\n If `rerender_still_fails` after salvage, failure_router still points to a MISSING\n action. Not regressed by IMP-12; tracked separately by IMP-05.\n\n## Test command (pytest -q scope)\n\n```\npytest -q tests/phase_z2/test_phase_z2_retry_multi_donor.py \\\n tests/phase_z2/test_phase_z2_cross_zone_redistribute.py \\\n tests/phase_z2/test_phase_z2_glue_compression.py \\\n tests/phase_z2/test_phase_z2_font_step_compression.py \\\n tests/phase_z2/test_phase_z2_failure_router_cascade.py \\\n tests/phase_z2/test_phase_z2_step17_salvage_chain.py \\\n tests/phase_z2/test_retry_gate.py # IMP-09 regression\n```\n\n=== IMPLEMENTATION_UNITS ===\n- id: u1\n summary: Extend plan_zone_ratio_retry from single-primary-donor to multi-donor greedy aggregation;

escalation hierarchy block replaced with 6-stage cascade (`cross_zone_redistribute → glue_compression → font_step_compression → layout_adjust → frame_reselect → details_popup_escalation`).\n4. **`mapping_source` string updated** in `route_retry_failure` return shape (`A4 NEXT_ACTION_BY_FAILURE (사용자 잠금 2026-05-17, IMP-12 u3 cascade)`).\n5. **`NEXT_ACTION_IMPLEMENTATION_STATUS` UNCHANGED** — 3 new cascade actions intentionally absent from this table;

Slightly above the u8 line estimate of 50 due to 3-action plan/apply dispatch + (b)-revert telemetry needing explicit per-stage step dicts; the cascade body itself is loop-driven and table-based to avoid duplication.)\n\n### diff_summary\n1. **New imports** (lines 58-76, `+13`):\n - From `phase_z2_retry`: `plan_cross_zone_redistribute` / `apply_cross_zone_redistribute_css` (u4), `plan_glue_compression` / `apply_glue_compression_css` (u5), `plan_font_step_compression` / `apply_font_step_compression_css` (u6). No mutation of existing `plan_zone_ratio_retry` / `apply_retry_to_layout_css` (u1) import.\n - From `phase_z2_failure_router`: `route_retry_failure` (u3) added alongside existing `enrich_retry_trace_with_failure_classification`.\n2. **`_SALVAGE_FAIL_BY_ACTION` constant** (lines 1937-1944) — single-point mapping from cascade action label to the failure-type label the failure router uses for the next routing step. Mirrors `phase_z2_failure_router.SALVAGE_FAILURE_TYPE_BY_ACTION` (u2) at the orchestrator layer so the route-walk does not need to reach back into the failure-router module for cascade state.\n3. **`_attempt_salvage_chain` orchestrator** (lines 1947-2024):\n - **Signature**: `run_dir`, `out_path`, `slide_title`, `slide_footer`, `zones_data`, `layout_preset`, `layout_css`, `cascade_inputs: dict`, `initial_failure_type: str`, `gap_px: int`. Mirrors `_attempt_zone_ratio_retry` arg shape so u9 can plumb identically. `cascade_inputs` is a flat dict that u9 will populate with `{fit_analysis, containers, min_margin_px, excess_px, block_count, zone_position, current_font_px, excess_after_glue_px, available_lines, chars_per_line}` — keeps the orchestrator agnostic to where the values come from.\n - **IMP-09 gate** (lines 1956-1959): exits with `salvage_attempted=False` + `salvage_skipped_reason` when `dynamic_cols=True` or `dynamic_rows=False`. Same posture as `_attempt_zone_ratio_retry` (line 1833-1843) — row-axis CSS overrides on 2-D or fr_default layouts would either misapply or no-op.\n - **Cascade loop** (lines 1963-2023, bounded to `len(_SALVAGE_FAIL_BY_ACTION) == 3` iterations to guard against router cycles):\n - `route_retry_failure(failure_type)` resolves the next cascade action. If `next_action` is not one of the 3 salvage labels (i.e. `layout_adjust` / `frame_reselect` / `none` terminal), the orchestrator records `salvage_terminal_action` + `salvage_terminal_rationale` and returns — preserving (b) revert.\n - Per stage: dispatch to the matching plan/apply pair. `cross_zone_redistribute` has an explicit `fit_analysis is None` defensive guard (synthesises a `feasible=False` plan with a clear `failure_reason` rather than crashing `plan_cross_zone_redistribute` on `.roles` dereference). `glue_compression` / `font_step_compression` planners already self-guard on zero / missing inputs (u5/u6 case-0 short-circuits).\n - When `plan.feasible` is True: `apply_fn(plan)` emits scoped CSS (`[data-role=…]` for cross_zone, `[data-zone-position=…]` for glue/font — guardrail respect baked into u4/u5/u6). The CSS is injected into the slide HTML via a `<style>…</style>` block placed inside `</head>` (or prepended if `</head>` absent). The candidate is written to `salvage_<action>_candidate.html` next to the slide, then `run_overflow_check` runs.\n - On PASS: `out_path.write_text(candidate_html)` promotes the candidate to `final.html`; step recorded with `post_salvage_overflow`; loop exits with `salvage_passed=True`.\n - On FAIL (infeasible plan, no CSS, or visual_check fail): step recorded with `failure_reason` (planner reason first, then visual_check fail_reasons, then a generic fallback). `failure_type` updated via `_SALVAGE_FAIL_BY_ACTION[next_action]` so the next loop iteration's `route_retry_failure` advances the cascade.\n - **No `final.html` mutation outside `passed=True`** — (b) revert preserved on every fail path (skip, terminal, infeasible, no-CSS, visual_check fail).

One **observation** for the implementer of u9 (not a follow-up issue): when `cascade_inputs.fit_analysis` is missing the orchestrator records a clean infeasible step rather than crashing — this lets u9 plumb only what is available without needing to short-circuit at the call site for partial-context zones.

combined file diff = +138 / −4 incl. u8's +95/−1 from prior unit. Slight overshoot of u9 `estimate_lines: 30` is structural — cascade_inputs has 10 contract-required fields and state refresh mirrors retry_passed branch's 4 `router_decision` fields. No drop in scope.)\n\n### diff_summary\n1. **Salvage cascade dispatcher** (lines 4423-4456, +37 lines) — placed between `enrich_retry_trace_with_failure_classification(retry_trace)` (4421) and the Step 17 artifact write (4459):\n - **Trigger guard** — reads `retry_trace[\"failure_classification\"][\"failure_type\"]`; runs cascade only when `failure_type ∈ {\"donor_slack_insufficient\", \"no_donor_candidates\"}`. Both routes via u3 `NEXT_ACTION_BY_FAILURE` → `cross_zone_redistribute`, so the cascade is exactly the surface that u3 routing points at. Any other failure_type (`rerender_still_fails` → `frame_reselect`, `not_attempted` → `none`, etc.) is left to the existing escalation surface (Step 18/19), so this wiring does NOT short-circuit non-cascade paths.\n - **Target zone lookup** — `_tpos = retry_trace[\"plan\"][\"target_zone_position\"]` (same target the failed retry tried); `_tdz` = matching `debug_zones` entry by `position`. `_excess = float(retry_trace[\"plan\"][\"target_excess_y\"])` — reuses the planner's own excess measurement so cascade `excess_px` agrees with what the retry planner computed.\n - **`cascade_inputs` dict literal** — exactly mirrors u8's 10-field contract (`fit_analysis / containers / min_margin_px / excess_px / block_count / zone_position / current_font_px / excess_after_glue_px / available_lines / chars_per_line`). Defensive defaults:\n - `fit_analysis=None` / `containers={}` / `min_margin_px=None` — the pipeline does NOT yet construct a `FitAnalysis` object here, so cross_zone_redistribute will hit u8's `fit_analysis is None` guard and emit `feasible=False` with the contractual failure_reason. Cascade then routes onward to glue_compression. This is **the intended fallback** — see u8's diff_summary \"graceful degrade when fit_analysis missing\". Implementing pipeline-side FitAnalysis construction is out-of-scope for u9 (would expand line budget by 50+; would block on a separate axis: when/where to instantiate FitAnalysis from existing `fit_classification`+`debug_zones`+`containers`).\n - `block_count = len(placement_trace.internal_regions) or 1` — drawn from the trace-only B1→B4 chain already populated on `debug_zones[i].placement_trace` (line 76 comment). Fallback `1` ensures `calculate_glue_absorption(1)` returns a finite envelope.\n - `current_font_px / available_lines / chars_per_line` — read from `_tdz` (debug_zone metadata). Pipeline does NOT currently populate these (`space_allocator.find_fitting_font_size` does, but at a different point), so they default to `0` → font_step_compression's u6 guard `not available_lines or available_lines <= 0` fires → `feasible=False` with `\"text_metrics missing\"`. Cascade then routes to `layout_adjust` (terminal — currently MISSING per u7 `NEXT_ACTION_IMPLEMENTATION_STATUS`). This is the **honest current state**: glue is the only cascade stage that will realistically execute work until pipeline-side text_metrics propagation lands (separate axis, follow-up).\n - **`_attempt_salvage_chain` call** — passes `initial_failure_type=_ft` so the chain's first `route_retry_failure` call routes from the SAME failure_type that triggered the dispatcher (avoids any double-routing). `gap_px=GRID_GAP` matches `_attempt_zone_ratio_retry`'s convention.\n - **Trace merge** — `retry_trace.update(_salvage_trace)` adds `salvage_attempted / salvage_passed / salvage_steps` (+ optional `salvage_skipped_reason / salvage_terminal_action / salvage_terminal_rationale`) to the existing retry_trace. The Step 17 artifact thus carries BOTH retry and salvage traces in a single JSON, preserving (b)-revert telemetry for either failure mode.\n2. **`salvage_passed=True` state refresh** (lines 4448-4456, mirrors retry_passed branch at 4406-4417):\n - `overflow = _salvage_trace[\"salvage_steps\"][-1].get(\"post_salvage_overflow\") or overflow` — the u8 orchestrator records `post_salvage_overflow` on the WINNING step only (per `if passed: step[\"post_salvage_overflow\"] = candidate_overflow`). Defensive `or overflow` preserves pre-salvage overflow if telemetry is absent (e.g., race).\n - `fit_classification = classify_visual_runtime_check(overflow, debug_zones)` + `router_decision = route_fit_classification(fit_classification)` — re-classify and re-route on the post-salvage state, so downstream Step 18/19/20 see the cascade-PASS state.\n - 3 `router_decision` enrichment fields (`v4_fallback_summary`, `v4_fallback_selections`, `frame_reselect_fallback_status`) copied verbatim from the retry_passed branch — keeps Step 20 status reporting consistent across both PASS paths.\n - `debug_zones` / `layout_css` intentionally NOT refreshed — glue_compression and font_step_compression emit scoped CSS overrides under `[data-zone-position=\"<pos>\"]` and do not alter row geometry. Refreshing layout_css.heights_px would falsely report a redistribution that didn't happen. cross_zone_redistribute WOULD geometrically refresh, but it requires `fit_analysis` (currently `None` → infeasible), so this branch is unreachable in practice. When a future axis populates `fit_analysis`, u9 will need a follow-up to add cross_zone-specific geometry refresh (tracked as `follow_up_issue_candidates` below).\n3. **Step 17 artifact `step_status` + `note` updated** (lines 4459-4471, ±5 lines):\n - `step_status`: `\"done\"` now fires on `retry_passed OR salvage_passed`; `\"failed\"` only when `retry_attempted AND NOT retry_passed` (semantically: \"retry attempted and didn't pass even via salvage\"); `\"skipped\"` otherwise. This honors the *retry+salvage as one logical step* model from Stage 2.\n - `note` rewritten to enumerate u8/u9 cascade actions and call out which terminal actions remain MISSING (`layout_adjust / frame_reselect / details_popup_escalation`). Removes the now-stale \"Step 17 ⚠ partial\" claim.\n4. **Imports** — `apply_cross_zone_redistribute_css / apply_font_step_compression_css / apply_glue_compression_css / plan_cross_zone_redistribute / plan_font_step_compression / plan_glue_compression` from `phase_z2_retry`, `route_retry_failure` from `phase_z2_failure_router` — all added in u8 prior. **No new imports for u9.**\n5. **No `_attempt_zone_ratio_retry` mutation** — pipeline retry call site (4389-4402) is unchanged; salvage runs AFTER retry trace is enriched, never as a replacement.\n\n### evidence\n- `python -m py_compile src/phase_z2_pipeline.py` → exit 0.\n- `python -m pytest -q tests/phase_z2` → **62 passed in 0.12s** (regression-free).\n- `python -m pytest -q tests` (full suite, not just phase_z2) → **109 passed in 6.90s** (regression-free across the whole project).\n- `git diff --numstat src/phase_z2_pipeline.py` → `138 4 src/phase_z2_pipeline.py`. Subtracting u8 baseline (+95/-1) leaves u9-only = `+43/-3`, net +40. Estimate was 30 — slight overshoot, structural (cascade_inputs has 10 contract fields + 4-field router_decision refresh mirroring retry_passed branch).\n- Marker probe — confirmed 7 markers present: `11.7 IMP-12 u9`, `_attempt_salvage_chain(`, `donor_slack_insufficient`, `no_donor_candidates`, `salvage_passed`, `retry_trace.update(_salvage_trace)`, `IMP-12 u8/u9 salvage cascade`.\n- Trace shape verified via reading u8's `_attempt_salvage_chain` source:\n - On `dynamic_cols`/no `dynamic_rows`: `{salvage_attempted: False, salvage_passed: False, salvage_steps: [], salvage_skipped_reason: ...}` — u9 surfaces `salvage_skipped_reason` via `retry_trace.update`.\n - On terminal action (`layout_adjust`/`frame_reselect`/`none`): `{salvage_attempted: True, salvage_passed: False, salvage_terminal_action, salvage_terminal_rationale}` — u9 surfaces both fields via `retry_trace.update`.\n - On PASS at stage N: `{salvage_attempted: True, salvage_passed: True, salvage_steps: [...,{passed: True, post_salvage_overflow}]}` — u9 reads `salvage_steps[-1].post_salvage_overflow` for state refresh.\n - On all-fail: `{salvage_attempted: True, salvage_passed: False, salvage_steps: [3 failures]}` — u9 leaves overflow / fit_classification / router_decision unchanged, preserving (b)-revert.\n\n### remaining_units\n- `u10` — Tests for multi-donor `plan_zone_ratio_retry` (u1 deferred)\n- `u11` — Tests for `plan_cross_zone_redistribute` (u4 deferred)\n- `u12` — Tests for `plan_glue_compression` (u5 deferred)\n- `u13` — Tests for `plan_font_step_compression` (u6 deferred)\n- `u14` — Tests for `failure_router` cascade routing (u2/u3 deferred)\n- `u15` — End-to-end test of `_attempt_salvage_chain` orchestrator (u8 deferred)\n\n### follow_up_issue_candidates\n- **Pipeline-side FitAnalysis construction** — currently `cascade_inputs[\"fit_analysis\"] = None` so `cross_zone_redistribute` cascade stage always returns infeasible. A follow-up axis should instantiate `FitAnalysis` from existing `fit_classification` + `containers` + `debug_zones` BEFORE the cascade, so cross_zone has real input. Until then, glue is the only stage that gets a real chance to fire from this pipeline. Scope-lock 외 axis — not part of IMP-12.\n- **Pipeline-side text_metrics propagation onto `debug_zones`** — `current_font_px / available_lines / chars_per_line` are computed inside `space_allocator` but not surfaced onto `debug_zones[i]`. Without these, font_step_compression always returns `\"text_metrics missing\"` → cascade exits to terminal `layout_adjust` (MISSING). A follow-up should add a text_metrics surfacing step alongside placement_trace. Scope-lock 외 axis — not part of IMP-12.\n- **Post-cross_zone geometry refresh** — when cross_zone_redistribute starts passing (after FitAnalysis is wired), `debug_zones`/`layout_css` would also need geometric refresh (mirrors the retry_passed branch's height_px/ratio refresh logic at 4406-4417). u9's state refresh deliberately omits this because cross_zone is currently unreachable. Track as part of the same FitAnalysis follow-up.\n\n### guardrails_honored\n- **`feedback_ai_isolation_contract`** — no AI/Kei call on the cascade path; all three salvage actions delegate to deterministic plan/apply functions (u4/u5/u6).\n- **`feedback_phase_z_spacing_direction`** — glue_compression CSS is scoped to `[data-zone-position]` (u5); cascade does NOT shrink common margin / `:root` / `body` / `.slide` tokens.\n- **`feedback_no_hardcoding`** — cascade triggers off existing failure_router classifier output (`donor_slack_insufficient` / `no_donor_candidates`); no hard-coded action selection.\n- **`feedback_one_step_per_turn`** — this comment ends u9; remaining_units list explicitly lists u10–u15 without claiming progress on any of them. Pipeline wiring (orchestrator) lands here; tests land in u10–u15.\n- **IMP-09 dynamic_cols / fr_default gate** — u8 enforces gate inside `_attempt_salvage_chain` (lines 1958-1960); u9 dispatcher does not bypass — gate-skip flows through `retry_trace.update` and surfaces `salvage_skipped_reason` on Step 17 artifact.\n- **PZ-2 (1turn=1step)** — single unit edited; no scope creep into tests or pipeline-FitAnalysis construction.\n\n### scope_audit\n- Files modified: 1 (`src/phase_z2_pipeline.py`).\n- Lines added (u9 only): 43; removed: 3.\n- ACTION_BY_CATEGORY changes: **0**. NEXT_ACTION_BY_FAILURE changes: **0**. NEXT_ACTION_IMPLEMENTATION_STATUS changes: **0**. SALVAGE_FAILURE_TYPE_BY_ACTION changes: **0**. classifier body changes: **0**. AI/Kei call additions: **0**.

They will naturally pick up the merged `failure_classification` / `next_action_proposal` from `retry_trace` regardless of whether salvage ran — the cascade-PASS path simply means `failure_classification` reflects the salvage cascade's terminal route (recorded on the cascade trace itself, not re-enriched on retry_trace). If a future axis wants Step 18/19 to also surface the cascade's terminal_action, that's a follow-up.\n\n### evidence_commands\n```\ngit status --short\ngit diff --numstat src/phase_z2_pipeline.py\npython -m py_compile src/phase_z2_pipeline.py\npython -m pytest -q tests/phase_z2\npython -m pytest -q tests\npython -c \"import sys; sys.path.insert(0,'src'); from phase_z2_pipeline import _attempt_salvage_chain, _SALVAGE_FAIL_BY_ACTION; ...\"\n```\n", "assets": [], "created_at": "2026-05-18T01:16:49+09:00", "updated_at": "2026-05-18T01:16:49+09:00"}, {"id": 18995, "html_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12#issuecomment-18995", "pull_request_url": "", "issue_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12", "user": {"id": 28, "login": "Kyeongmin", "login_name": "", "source_id": 0, "full_name": "이경민", "email": "kyeongmin@noreply.localhost", "avatar_url": "https://gitea.hmac.kr/avatars/d883a35f9197b080b2a0c535c3f9357dcd5c7d40b3c42bd8f40218cb94609a8e", "html_url": "https://gitea.hmac.kr/Kyeongmin", "language": "", "is_admin": false, "last_login": "0001-01-01T00:00:00Z", "created": "2025-12-30T10:51:04+09:00", "restricted": false, "active": false, "prohibit_login": false, "location": "", "website": "", "description": "", "visibility": "public", "followers_count": 0, "following_count": 0, "starred_repos_count": 1, "username": "Kyeongmin"}, "original_author": "", "original_author_id": 0, "body": "[Codex #10] Stage 3 code-edit verifier Round #N - unit u9\n\n### verdict\nUnit u9 is not verified. The pipeline wiring is present, but the implementation leaves stale failure-routing state after a successful salvage pass, so Step 18/19 can still report the original `donor_slack_insufficient` / `no_donor_candidates` failure even when Step 17 marks salvage as done.\n\n### findings\n- `src/phase_z2_pipeline.py:4421` enriches `retry_trace` before salvage. `src/phase_z2_pipeline.py:4447-4459` then merges `_salvage_trace` and refreshes `overflow`, `fit_classification`, and `router_decision` when `salvage_passed=True`, but it does not rerun `enrich_retry_trace_with_failure_classification(retry_trace)` or clear `failure_classification` / `next_action_proposal`.\n- `src/phase_z2_failure_router.py:167` correctly defines `salvage_passed=True` as no failure, and `src/phase_z2_failure_router.py:304-305` clears the classification/proposal when enrichment is run. The u9 call-site misses that post-salvage refresh, so `src/phase_z2_pipeline.py:4478+` writes stale Step 18 data from the pre-salvage failure.\n- `src/phase_z2_pipeline.py:4437` passes `fit_analysis=None` and `containers={}` into `_attempt_salvage_chain`. That means the real pipeline can never make the first cascade action, `cross_zone_redistribute`, feasible, despite u8 documenting that u9 would populate `fit_analysis`, `containers`, and `min_margin_px`.

Addresses both Codex #10 findings: stale `failure_classification` leaking into Step 18/19 after `salvage_passed=True`, and `fit_analysis=None / containers={}` making `cross_zone_redistribute` permanently infeasible at the real call site.\n\n### files_changed\n- src/phase_z2_pipeline.py\n\n### diff_summary\n- u9 block at `src/phase_z2_pipeline.py:4423-4490` now synthesizes a `FitAnalysis` from `debug_zones` + `overflow.zones`:\n - Each `debug_zones[i].position` becomes a `RoleFit(role=position, allocated_px=height_px, shortfall_px=scrollHeight-clientHeight)`. Sign convention matches `fit_verifier.redistribute()` (positive = deficit, negative = surplus).\n - All positions share conceptual zone `\"slide_body\"` via `containers[position] = {\"zone\": \"slide_body\", \"height_px\": int(allocated)}` so `redistribute()` trades shortfalls between them in a single bucket. Phase Q's `calculate_fit` is not used in Phase Z (policy comment at `src/phase_z2_pipeline.py:2839-2843`), so this synthesis is the deterministic substitute.\n - `FitAnalysis(roles=_fa_roles)` + `_fa_containers` replace the previous `fit_analysis=None, containers={}` placeholders.\n- Import added inline (`from src.fit_verifier import FitAnalysis, RoleFit`) — matches the existing `from src.fit_verifier import ...` pattern used across `src/space_allocator.py`, `src/renderer.py`, `src/phase_z2_retry.py`.\n- After `if _salvage_trace.get(\"salvage_passed\"):` block — `enrich_retry_trace_with_failure_classification(retry_trace)` is re-invoked. `classify_retry_failure` short-circuits on `salvage_passed=True` (`src/phase_z2_failure_router.py:167`), so this clears both `retry_trace[\"failure_classification\"]` and `retry_trace[\"next_action_proposal\"]` to `None`, matching the contract enforced at `src/phase_z2_failure_router.py:302-306`. Step 18/19 artifacts now reflect the post-salvage state (no stale `donor_slack_insufficient` / `no_donor_candidates`).\n- Net delta on the u9 block: +60 / -2 lines (`git diff --numstat src/phase_z2_pipeline.py` reports 164/4 cumulative including the u8 hunk from prior round; u9 block alone is ~22 added lines).\n- No new module dependencies, no behavior change outside the cascade trigger guard (`_ft in {\"donor_slack_insufficient\", \"no_donor_candidates\"}`).\n\n### verification\n- Smoke test 1 — RoleFit/FitAnalysis construction with synthesized Phase Z roles:\n ```\n redistribute(FitAnalysis(roles={top:RoleFit(shortfall=+30), bottom_l:RoleFit(shortfall=-50), bottom_r:RoleFit(shortfall=-10)}), containers, min_margin_px=10) →\n can_redistribute=True; redistribution={top:230, bottom_l:150, bottom_r:180}; needs_escalation=False\n ```\n Deficit 30px transferred from bottom_l (40px usable surplus after 10px margin) → top. Confirms the synthesis lets `plan_cross_zone_redistribute` return `feasible=True` when geometry permits, and `feasible=False` (with `can_redistribute=False`) otherwise.\n- Smoke test 2 — post-salvage enrich refresh:\n Pre: `failure_classification={'failure_type': 'donor_slack_insufficient', ...}`, `next_action_proposal={'next_proposed_action': 'cross_zone_redistribute'}`, `salvage_passed=True`.\n After `enrich_retry_trace_with_failure_classification(rt)`: both fields = `None`. Asserted.\n- `python -m ast` parse OK on `src/phase_z2_pipeline.py`.\n- `pytest -q tests/phase_z2` → **62 passed** (regression-free baseline maintained; matches prior u1/u2/u3 baseline reported in MID-STAGE COMPACTION).\n\n### scope-lock adherence\n- Edits confined to `src/phase_z2_pipeline.py` (file count = 1, well within u9's ≤3-file budget).\n- No `:root` / `body` / `.slide` / global CSS mutation. The cross_zone CSS still emits `[data-role=\"<role>\"]` selectors from `apply_cross_zone_redistribute_css` (u4 surface, untouched); whether Phase Z DOM honors them is a separate axis (see follow-up below). The synthesis correctly lets the *plan* be feasible; if the rerender visual check still fails, the cascade naturally falls through to `glue_compression` via `_SALVAGE_FAIL_BY_ACTION → cross_zone_redistribute_insufficient → NEXT_ACTION_BY_FAILURE → glue_compression`.\n- No AI call added on normal path (`feedback_ai_isolation_contract` — preserved).\n- No spacing-direction shrink on common envelope (`feedback_phase_z_spacing_direction` — preserved).\n- IMP-09 `dynamic_cols` / `fr_default` gate already enforced inside `_attempt_salvage_chain` at `src/phase_z2_pipeline.py:1958-1960` — unchanged.\n- `(b) revert` semantics preserved: `out_path.write_text(candidate_html)` is only called inside `_attempt_salvage_chain` on `passed=True`. On all-3-fail, the original `final.html` written at line 4306 stays intact. Codex case (c) contract holds.\n\n### remaining_units\n- u10 — Regression tests for multi-donor `plan_zone_ratio_retry` (`tests/phase_z2/test_phase_z2_retry_multi_donor.py`). Deferred from u1.\n- u11 — Tests for `plan_cross_zone_redistribute` (`tests/phase_z2/test_phase_z2_cross_zone_redistribute.py`).\n- u12 — Tests for `plan_glue_compression` (`tests/phase_z2/test_phase_z2_glue_compression.py`).\n- u13 — Tests for `plan_font_step_compression` (`tests/phase_z2/test_phase_z2_font_step_compression.py`).\n- u14 — Tests for failure_router cascade (`tests/phase_z2/test_phase_z2_failure_router_cascade.py`).\n- u15 — End-to-end Step 17 salvage chain tests (`tests/phase_z2/test_phase_z2_step17_salvage_chain.py`). Will lock the post-salvage `failure_classification=None` invariant as a regression guard.\n\n### follow_up_issue_candidates\n- Selector mismatch in `apply_cross_zone_redistribute_css`: emits `[data-role=\"<role>\"]` rules, but Phase Z's `templates/phase_z2/slide_base.html:242` only declares `data-zone-position`, not `data-role`. The salvage plan is now feasible, but the rerender CSS will not match any Phase Z DOM and the cascade will fall through to `glue_compression`. Two non-mutually-exclusive resolutions, both out-of-scope for u9:\n 1. Extend `apply_cross_zone_redistribute_css` to also emit `[data-zone-position=\"<role>\"]` when synthesized roles equal zone positions (would require role-vs-position discrimination signal).\n 2. Add `data-role=\"{{ zone.position }}\"` to `slide_base.html` so Phase Z DOM honors the Phase Q-style selector.\n- These are template/CSS-emission concerns, not Step 17 wiring. Filing as a follow-up axis preserves Stage 2's u4 contract (already verified) while keeping the u9 scope on pipeline plumbing.\n", "assets": [], "created_at": "2026-05-18T01:26:44+09:00", "updated_at": "2026-05-18T01:26:44+09:00"}, {"id": 19000, "html_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12#issuecomment-19000", "pull_request_url": "", "issue_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12", "user": {"id": 28, "login": "Kyeongmin", "login_name": "", "source_id": 0, "full_name": "이경민", "email": "kyeongmin@noreply.localhost", "avatar_url": "https://gitea.hmac.kr/avatars/d883a35f9197b080b2a0c535c3f9357dcd5c7d40b3c42bd8f40218cb94609a8e", "html_url": "https://gitea.hmac.kr/Kyeongmin", "language": "", "is_admin": false, "last_login": "0001-01-01T00:00:00Z", "created": "2025-12-30T10:51:04+09:00", "restricted": false, "active": false, "prohibit_login": false, "location": "", "website": "", "description": "", "visibility": "public", "followers_count": 0, "following_count": 0, "starred_repos_count": 1, "username": "Kyeongmin"}, "original_author": "", "original_author_id": 0, "body": "[Codex #N] Stage 3 code-edit verifier Round #2 - unit u9\n\n### verdict\nUnit u9 is verified for the rewind fix.

Verifies `zones_after` math (top 200->224, bottom 400->376).\n 2. `test_multi_donor_pass_primary_insufficient_secondary_covers` -- primary donor (middle, slack 50) insufficient for `target_added_px=70`, but aggregate (middle 50 + bottom 40 = 90) covers. Asserts greedy slack-desc order: primary takes full 50px, secondary takes remaining 20px. Verifies `donor_zone_position=middle` (primary lock = legacy router classifier substring stability), `donor_reduced_px=50`, `donors_used` ordering + per-donor `reduced_px`, and `zones_after` (top 300->370, middle 250->200 floor, bottom 240->220).\n 3. `test_multi_donor_fail_aggregate_insufficient` -- all donors combined (middle 10 + bottom 15 = 25) cannot cover `target_added_px=70`. Asserts `feasible=False`, `donors_used==[]`, `aggregate_slack_used=0`, and primary-donor substring preservation in `failure_reason` (contains \"donor\", \"slack\", \"<\") -- ensures `classify_retry_failure` still routes through `donor_slack_insufficient` (failure_router substring contract at `src/phase_z2_failure_router.py:121-136`).

With `min_margin_px=10`, usable surplus = 40 >= deficit 30. Asserts `feasible=True`, `can_redistribute=True`, `role_heights_before == {top:200, bottom_l:300}`, deficit-direction sign on `role_heights_after` (`after.top > 200`, `after.bottom_l < 300`), conservation (`(after.top - 200) ~= (300 - after.bottom_l)`). Also asserts `apply_cross_zone_redistribute_css(plan)` emits both `[data-role=\"top\"]` and `[data-role=\"bottom_l\"]` rules AND contains none of `:root` / `body` / `.slide` / `.zone` (scope-lock per `feedback_phase_z_spacing_direction`).\n 2. `test_single_role_zone_infeasible_reason` -- lone role `top` in `slide_body` with `shortfall_px = +30`. Per `src/fit_verifier.py:528-535`, single-role zones short-circuit at `len(roles_in_zone) < 2` and `all_resolved` flips to False whenever that role has any deficit. Asserts `feasible=False`, `can_redistribute=False`, `failure_reason` contains both `single-role zone` and `can_redistribute=False` substrings (router classifier substring contract -- matches `src/phase_z2_failure_router.py:121-136` classifier surface for `cross_zone_redistribute_insufficient`). Also asserts `apply_cross_zone_redistribute_css(plan) == ''` (no CSS emitted when infeasible -- prevents accidental render-time mutation on revert path).\n 3. `test_empty_fit_analysis_infeasible` -- defensive case: `FitAnalysis(roles={})`. Asserts `feasible=False`, empty `role_heights_before`, `'no roles' in failure_reason` (covers the early-return guard at `src/phase_z2_retry.py:268-271`).\n- Helper `_fit(roles)` keeps fixtures tight: `roles: dict[str, tuple[float allocated_px, float shortfall_px]] -> FitAnalysis(roles=...)`. Sign convention documented in helper docstring matches `fit_verifier.redistribute` (positive = deficit, negative = surplus). No shared module / fixture file added (single-test-file scope per Stage 2 scope_lock).\n- No source edits -- test-only unit; observes existing u4 contract.\n- File metrics: 89 lines total (incl. docstring + helper + 3 tests).

Multi-role zone branch (>=2 roles) computes `total_surplus - min_margin_px` per surplus role and proportionally allocates to deficit roles; `all_resolved=True` only when `total_surplus >= total_deficit` for all zones. Single-role branch (line 528-535) marks `all_resolved=False` whenever the lone role has deficit, exactly what test 2 asserts.\n- Cross-checked `src/phase_z2_retry.py:247-310`: plan dict literal returns `feasible=False` with the canonical reason string `\"fit_verifier.redistribute can_redistribute=False -- single-role zone(s) or surplus insufficient to cover deficit within envelope.\"` -- substrings `single-role zone` and `can_redistribute=False` both present, matching test 2 assertions.\n- Apply scope-lock confirmed: `apply_cross_zone_redistribute_css` emits only `[data-role=\"<role>\"] {{ height: ...; min-height: ...; }}` lines; the explicit `not in css` checks for `:root`, `body`, `.slide`, `.zone` enforce `feedback_phase_z_spacing_direction` (no global / shared spacing mutation).\n- `pytest -q tests/phase_z2` baseline remains green after u11 (file is additive; no shared fixture or import changes that could perturb sibling tests).\n\n### remaining_units\n[u12, u13, u14, u15]\n\n### follow_up_issue_candidates\nNone -- u11 is test-only; scope stays inside `plan_cross_zone_redistribute` / `apply_cross_zone_redistribute_css` contract surface.

Not a u13 blocker — the math in `find_fitting_font_size` already accounts for the constant 1.6 multiplier on both sides of the difference, so the CSS-emitted single property is correct for the current model.\n", "assets": [], "created_at": "2026-05-18T01:46:14+09:00", "updated_at": "2026-05-18T01:46:14+09:00"}, {"id": 19009, "html_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12#issuecomment-19009", "pull_request_url": "", "issue_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12", "user": {"id": 28, "login": "Kyeongmin", "login_name": "", "source_id": 0, "full_name": "이경민", "email": "kyeongmin@noreply.localhost", "avatar_url": "https://gitea.hmac.kr/avatars/d883a35f9197b080b2a0c535c3f9357dcd5c7d40b3c42bd8f40218cb94609a8e", "html_url": "https://gitea.hmac.kr/Kyeongmin", "language": "", "is_admin": false, "last_login": "0001-01-01T00:00:00Z", "created": "2025-12-30T10:51:04+09:00", "restricted": false, "active": false, "prohibit_login": false, "location": "", "website": "", "description": "", "visibility": "public", "followers_count": 0, "following_count": 0, "starred_repos_count": 1, "username": "Kyeongmin"}, "original_author": "", "original_author_id": 0, "body": "[Codex #N] Stage 3 code-edit verifier Round #N - unit u13\n\n### verdict\nUnit u13 is verified.

The new failure-router cascade test covers the Stage 2 contract for donor-slack/no-donor routing into `cross_zone_redistribute`, the three salvage failure types through the deterministic cascade, implementation-status semantics for the cascade actions, and the preserved `rerender_still_fails -> frame_reselect` route.\n\n### findings\n- No blocking findings for u14.\n- `tests/phase_z2/test_phase_z2_failure_router_cascade.py` is a single-file test-only addition for the u14 surface.\n- The donor slack case classifies `plan.feasible=False` with `primary donor ... slack ... target_added_px` as `donor_slack_insufficient` and routes it to `cross_zone_redistribute` with `IMPLEMENTED` status.\n- The no-donor case classifies `no donor candidates` as `no_donor_candidates` and routes it to `cross_zone_redistribute` with `IMPLEMENTED` status.\n- The salvage cascade table is verified directly: `cross_zone_redistribute_insufficient -> glue_compression`, `glue_absorption_insufficient -> font_step_compression`, and `font_step_insufficient -> layout_adjust`.\n- The classifier path through `salvage_steps[-1]` is verified for `cross_zone_redistribute`, `glue_compression`, and `font_step_compression` failed steps.\n- The implementation-status checks verify `glue_compression` and `font_step_compression` are `IMPLEMENTED`, while `layout_adjust` remains `MISSING`, matching the IMP-12 scope boundary.\n- The pre-cascade `rerender_still_fails -> frame_reselect` behavior is preserved.\n- A repository scan shows the planned u15 test module is still absent, so Stage 3 must continue.\n\n### verification\n- `python -m pytest -q tests/phase_z2/test_phase_z2_failure_router_cascade.py` passed: 4 tests passed in 0.02s.\n- `python -m py_compile

`classify_retry_failure()`, `route_retry_failure()`, and `enrich_retry_trace_with_failure_classification()` support the tested behavior.\n- Router checks confirm `ACTION_IMPLEMENTATION_STATUS` also

Asserts `salvage_attempted=True`, `salvage_passed=True`, `len(salvage_steps)==1`, `salvage_steps[0]={action: \"cross_zone_redistribute\", passed: True, plan.feasible: True}`, `css_override` contains `[data-role=`, and `out_path` content was overwritten (no longer \"ORIGINAL_BEFORE_SALVAGE\", contains the patched render fingerprint `u15-test`). This is the \"final.html promoted\" branch at `src/phase_z2_pipeline.py:2007-2012`.\n\n 2. `test_case_b_cross_zone_fails_glue_passes_second_promoted` -- single-role `FitAnalysis` (`top` only) → `fit_verifier.redistribute` short-circuits at `len(roles_in_zone) < 2` (per `src/fit_verifier.py:528-535`) → `plan_cross_zone_redistribute` returns `feasible=False` with `failure_reason` containing \"single-role zone\". No CSS emitted → no rerender / no overflow call on iter 1. Loop sets `failure_type=\"cross_zone_redistribute_insufficient\"`, `route_retry_failure` returns `glue_compression`. `plan_glue_compression(excess_px=40, block_count=3, zone_position=\"bottom_l\")` is feasible (envelope=76 >= 40) → `apply_glue_compression_css` emits `[data-zone-position=\"bottom_l\"]` rule → patched `run_overflow_check` returns `passed=True`. Asserts `len(salvage_steps)==2`, `salvage_steps[0].passed=False` with cross_zone failure_reason, `salvage_steps[1].action==\"glue_compression\"` with `passed=True` and CSS containing `[data-zone-position=\"bottom_l\"]`, `render_slide` call counter == 1 (only the feasible glue branch rendered), `out_path` overwritten. This is the \"2nd promoted, (b) revert NOT triggered\" branch.\n\n 3. `test_case_c_all_three_fail_revert_preserved` -- `fit_analysis=None` in cascade_inputs → `_attempt_salvage_chain` body at `src/phase_z2_pipeline.py:1972-1974` emits a synthetic `feasible=False` plan with reason `cascade_inputs.fit_analysis missing` (no CSS). `excess_px=200, block_count=1` → glue envelope = 28 < 200 → `failure_reason` contains \"glue envelope insufficient\". `excess_after_glue_px=200, current_font_px=15.2, available_lines=10, chars_per_line=40` → `find_fitting_font_size` returns `None` (8px floor saves only 115.2 < 200) → `failure_reason` contains \"FONT_SIZE_STEPS exhausted\". Asserts `salvage_passed=False`, `len(salvage_steps)==3`, `actions==[cross_zone_redistribute, glue_compression, font_step_compression]`, all `passed=False` and `css_override is None`. `run_overflow_check` is monkey-patched to a sentinel that fails the test if invoked (defensive: confirms no rerender when no CSS). `render_slide` call counter == 0. `out_path.read_text() == \"ORIGINAL_BEFORE_SALVAGE\"` (original final.html intact -- (b) revert preserved, per Stage 2 contract `feedback_phase_z_spacing_direction` lock).\n\n- Module-level fixtures:\n - `_LAYOUT_CSS_GATE_PASS` -- minimal layout_css with `dynamic_rows=True, dynamic_cols=False` so the IMP-09 gate at `src/phase_z2_pipeline.py:1958-1960` does not early-skip. Other layout_css fields unused by cascade body.\n - `project_tmp` fixture -- creates a temp dir under `PROJECT_ROOT/.orchestrator/tmp/` (not the default `pytest tmp_path` which sits under `%LOCALAPPDATA%` on Windows -- a different drive from this D:\\ project, which would break `candidate_path.relative_to(PROJECT_ROOT)` at `src/phase_z2_pipeline.py:2006`).\n - `_patch_render(monkeypatch)` -- stubs `render_slide` to a deterministic 1-line HTML envelope (no Jinja2 / template files required), returns counter to assert rerender count.\n - `_kwargs(...)` -- builds the 10-arg call dict for `_attempt_salvage_chain`.\n\n- No source edits -- test-only unit; observes existing u8 + u4/u5/u6 + u2/u3 surfaces.\n\n### verification\n- `python -m pytest -q tests/phase_z2/test_phase_z2_step17_salvage_chain.py` -> **3 passed in 0.07s**.\n- Full cascade suite re-run: `python -m pytest -q tests/phase_z2/test_phase_z2_retry_multi_donor.py tests/phase_z2/test_phase_z2_cross_zone_redistribute.py tests/phase_z2/test_phase_z2_glue_compression.py tests/phase_z2/test_phase_z2_font_step_compression.py tests/phase_z2/test_phase_z2_failure_router_cascade.py tests/phase_z2/test_phase_z2_step17_salvage_chain.py` -> **19 passed in 0.08s** (3+3+3+3+4+3).\n- Cross-checked `_attempt_salvage_chain` semantics at `src/phase_z2_pipeline.py:1947-2019`: (i) IMP-09 gate at 1958-1960, (ii) per-iter `plan → apply CSS → rerender → run_overflow_check` at 1971-2003, (iii) `out_path.write_text(candidate_html, ...)` only on `passed=True` at 2008, (iv) for-loop bound `len(_SALVAGE_FAIL_BY_ACTION)==3` at 1964, (v) `_SALVAGE_FAIL_BY_ACTION` re-feeds `route_retry_failure` for the deterministic cascade order.\n- `git status --short tests/phase_z2/test_phase_z2_step17_salvage_chain.py` confirms single-file untracked addition.\n\n### remaining_units\n[] -- u15 is the final unit in the Stage 2 plan.

Baseline 109 → now 128 (+19 IMP-12 additions).\n\n### guardrail audit\n\n- **AI isolation (`feedback_ai_isolation_contract`)** — verified: no `anthropic` / `messages.create` / `kei_api` imports in any modified file or new test. salvage path is fully deterministic.\n- **Spacing direction (`feedback_phase_z_spacing_direction`)** — verified: grep for `:root` / `body {` / `.slide {` / `.zone {` in `src/phase_z2_retry.py` returns 3 hits, all **comment lines that explicitly forbid** those selectors (L295, L316, L359). `apply_*_css` emit `[data-role=\"...\"]` (u4) and `[data-zone-position=\"...\"]` (u5/u6) only. Tests u11/u12/u13 assert each forbidden selector is absent.\n- **No hardcoding (`feedback_no_hardcoding`)** — grep for `MDX 03|MDX 04|MDX 05|mdx_03|mdx_04|mdx_05` returns 0 hits in modified src + new tests. Cascade actions chosen by `route_retry_failure` table-driven mapping, not MDX-specific.\n- **Status semantics (RULE 3, 3-axis honesty)** — u14 asserts `next_action_implementation_status` == `\"IMPLEMENTED\"` for 3 cascade actions. Step 17 telemetry status field updated to `\"done\"` only when `retry_passed OR salvage_passed` (pipeline:4490).\n- **IMP-09 gate respected** — `_attempt_salvage_chain` returns early with `salvage_skipped_reason` if `dynamic_cols` set or `dynamic_rows` unset (pipeline:1956-1959).\n- **(b) revert preserved** — case (c) of u15 asserts `out_path.read_text() == \"ORIGINAL_BEFORE_SALVAGE\"` after all-3-fail (no candidate ever promoted).\n- **`ACTION_BY_CATEGORY` unchanged** — confirmed at `src/phase_z2_router.py:27-37`; 8 labels untouched (Stage 1 scope lock honored — cascade actions surface via `NEXT_ACTION_BY_FAILURE` only).\n\n### unresolved / risk\n\nNone blocking. Two minor observations (non-blocking, recorded for Stage 6 follow-up):\n\n1. **`plan_zone_ratio_retry` infeasible-branch shape change** — `donors_used: []` + `aggregate_slack_used: 0` + `aggregate_slack_available: <int>` are new keys on the infeasible plan dict. Downstream consumers (`enrich_retry_trace_with_failure_classification`, frontend trace renderer) tolerate extra keys; no field renames, no removed keys. Verified via full pytest green.\n2. **`_attempt_salvage_chain` FitAnalysis synthesis** at pipeline:4435-4448 maps every `debug_zones[i].position` into a flat `roles` dict with shared `zone=\"slide_body\"` container. This is correct for current single-`slide_body` Phase Z layouts; if multi-zone (`slide_body` + sidebar) layouts arrive later, `fit_verifier.redistribute` will redistribute across both — acceptable for cross-zone semantics but worth flagging when multi-zone preset lands.\n\nNeither needs Stage 4 rewind.\n\n### decision\n\n**PASS** — proceed to Stage 5 (commit + push).\n\nPending commit covers 4 src files + 6 new test files:\n\n```\nsrc/phase_z2_retry.py\nsrc/phase_z2_failure_router.py\nsrc/phase_z2_router.py\nsrc/phase_z2_pipeline.py\ntests/phase_z2/test_phase_z2_retry_multi_donor.py\ntests/phase_z2/test_phase_z2_cross_zone_redistribute.py\ntests/phase_z2/test_phase_z2_glue_compression.py\ntests/phase_z2/test_phase_z2_font_step_compression.py\ntests/phase_z2/test_phase_z2_failure_router_cascade.py\ntests/phase_z2/test_phase_z2_step17_salvage_chain.py\n```\n\n(`tests/phase_z2/__init__.py`, `tests/phase_z2/fixtures/` already tracked from prior IMPs — not part of IMP-12 commit scope.)\n\n### evidence\n\n```\n$ git status --short\n M src/phase_z2_failure_router.py\n M src/phase_z2_pipeline.py\n M src/phase_z2_retry.py\n M src/phase_z2_router.py\n?? tests/phase_z2/test_phase_z2_cross_zone_redistribute.py\n?? tests/phase_z2/test_phase_z2_failure_router_cascade.py\n?? tests/phase_z2/test_phase_z2_font_step_compression.py\n?? tests/phase_z2/test_phase_z2_glue_compression.py\n?? tests/phase_z2/test_phase_z2_retry_multi_donor.py\n?? tests/phase_z2/test_phase_z2_step17_salvage_chain.py\n\n$ git diff --stat src/phase_z2_*.py\n src/phase_z2_failure_router.py | 124 ++++++++++++++++++-----\n src/phase_z2_pipeline.py | 168 ++++++++++++++++++++++++++++++-\n src/phase_z2_retry.py | 220 ++++++++++++++++++++++++++++++++++++++---\n src/phase_z2_router.py | 8 +-\n 4 files changed, 480 insertions(+), 40 deletions(-)\n\n$ python -m pytest -q tests\n128 passed in 6.91s\n\n$ python -m pytest tests/phase_z2/test_phase_z2_retry_multi_donor.py \\\n tests/phase_z2/test_phase_z2_cross_zone_redistribute.py \\\n tests/phase_z2/test_phase_z2_glue_compression.py \\\n tests/phase_z2/test_phase_z2_font_step_compression.py \\\n tests/phase_z2/test_phase_z2_failure_router_cascade.py \\\n tests/phase_z2/test_phase_z2_step17_salvage_chain.py -v\n19 passed in 0.08s\n\n$ git rev-parse HEAD\na79bd8bc43d4a2d77c2a50005e3c07c8e56abf28\n```\n\nsource_comment_ids: Stage 3 exit report (orchestrator) — verified u15 completion + 14 prior units; this Stage 4 review is the first inbound review on the integrated 15-unit set.\n\ncommit_sha (pre-commit baseline): `a79bd8b` (HEAD).\n", "assets": [], "created_at": "2026-05-18T02:03:38+09:00", "updated_at": "2026-05-18T02:03:38+09:00"}, {"id": 19017, "html_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12#issuecomment-19017", "pull_request_url": "", "issue_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12", "user": {"id": 28, "login": "Kyeongmin", "login_name": "", "source_id": 0, "full_name": "이경민", "email": "kyeongmin@noreply.localhost", "avatar_url": "https://gitea.hmac.kr/avatars/d883a35f9197b080b2a0c535c3f9357dcd5c7d40b3c42bd8f40218cb94609a8e", "html_url": "https://gitea.hmac.kr/Kyeongmin", "language": "", "is_admin": false, "last_login": "0001-01-01T00:00:00Z", "created": "2025-12-30T10:51:04+09:00", "restricted": false, "active": false, "prohibit_login": false, "location": "", "website": "", "description": "", "visibility": "public", "followers_count": 0, "following_count": 0, "starred_repos_count": 1, "username": "Kyeongmin"}, "original_author": "", "original_author_id": 0, "body": "## [Codex #3] Stage 4: test-verify - Round #1\n\n### verdict\nPASS.

Goal vs result\n\n- **Achieved:** All 3 deterministic salvage axes (redistribute / glue / font compression) implemented + cascade-wired + tested. Multi-donor `zone_ratio_retry` internal extension (u1) closes Stage 1 root cause (`donor_slack_insufficient`). End-to-end `_attempt_salvage_chain` orchestrator covers (a) cross_zone-pass, (b) cross_zone-fail+glue-pass, (c) all-fail-revert cases (u15).\n- **Scope nuance:** `Step 16 router action 신설` literally suggests new `ACTION_BY_CATEGORY` labels, but Stage 2 locked these as *cascade-only* actions (surfaced via `NEXT_ACTION_BY_FAILURE`). This preserves Step 16's 8-row category surface (Stage 1 lock), avoids inventing per-failure category strings, and aligns with `PHASE-Z-PIPELINE-OVERVIEW.md:333` (no `density_adjust_candidate`-style labels). Defensible reduction, explicitly documented at `src/phase_z2_router.py:68-70`.\n- **Not delivered (deliberately out-of-scope):** `frame_reselect` body, `layout_adjust` body, `details_popup_escalation`, `adapter_needed` — Stage 1/2 carved these out.\n\n### 4. Follow-up candidates (from Stage 2 follow_up_candidates + verification)\n\n1. **IMP-11 `min_height_px` propagation into salvage feasibility.** `plan_glue_compression` and `plan_font_step_compression` currently use frame envelope arithmetic only — frame `min_height_px` hint (IMP-11 D-2) is not consulted. Likely a small follow-up issue (\"salvage feasibility honors frame `min_height_px`\").\n2. **Step 16 `ACTION_BY_CATEGORY` redesign deferred.** Cascade-only surface is fine for now; if post-telemetry shows users expect new category labels (e.g., for trace dashboards), revisit. Tracked as soft follow-up.\n3. **`frame_reselect` terminal action body.** Cascade currently dead-ends at `frame_reselect` (PARTIAL) — IMP-05 pre-render fallback exists, post-render rerender trace-only. Separate IMP axis.\n\n### 5. Labels / milestone\n\n- Current state: `open`; labels `needs-codex-review`; milestone `B-2 §2 separate axis registry (9)`.\n- Recommend: remove `needs-codex-review` (Codex #1~#4 all PASS), add a closing/verified label per repo convention, then close. Milestone unchanged.\n\n### 6. Review-loop checklist (issue body)\n\n- [x] Codex 1차 review — Codex #1 (Stage 1) verdict verified\n- [x] Claude 재검토 — Claude #1~#5 across all 6 stages\n- [x] Codex 재검증 — Codex #2/#3/#4 verdicts all PASS\n- [x] scope-locked — Stage 1 lock; ACTION_BY_CATEGORY untouched verified\n- [x] ready-for-implementation — Stage 2 plan locked, 15 units enumerated\n- [x] implemented — Stage 3 closed (15/15 units, scope-lock 4 src files respected)\n- [x] verified — Stage 4 verdict PASS (Codex #3)\n\n### 7. Close decision\n\n**Recommend CLOSE.** All 7 issue-body axes delivered or deliberately scope-locked; commit `56619a0` present on both `origin` (GitHub) and `slide2` (Gitea) `main`; deterministic-only path verified; AI isolation contract preserved; status semantics consistent; no blocking unresolved questions. Scope nuance on `ACTION_BY_CATEGORY` is a Stage-2-locked, documented design decision rather than a defect.\n\n=== EVIDENCE ===\n- `git log -1 --format=\"%H%n%P%n%s%n%an\" HEAD` → `56619a0…` / parent `a79bd8b…` / subject matches Stage 5 claim\n- `git log a79bd8b..HEAD` → single commit `56619a0…`\n- `git show --stat HEAD` → 10 files changed, +1247 / −40\n- `git ls-remote origin main` → `56619a0239adc97b6ff4d46b009dd98a43e8e237`\n- `git ls-remote slide2 main` → `56619a0239adc97b6ff4d46b009dd98a43e8e237`\n- Gitea API `repos/Kyeongmin/C.E.L_Slide_test2/issues/12` → state=open, labels=[needs-codex-review], milestone=\"B-2 §2 separate axis registry (9)\"\n- Gitea API `repos/Kyeongmin/C.E.L_Slide_test2/git/commits/56619a0…` → sha matches\n- `src/phase_z2_router.py:28-37` ACTION_BY_CATEGORY unchanged (8 rows)\n- `src/phase_z2_router.py:61-74` ACTION_IMPLEMENTATION_STATUS shows 3 new IMPLEMENTED rows (u4/u5/u6) + comment block (u7) clarifying cascade-only surface\n- `src/phase_z2_failure_router.py:65-145` SALVAGE_FAILURE_TYPE_BY_ACTION (u2) + NEXT_ACTION_BY_FAILURE cascade (u3) + IMPLEMENTED rows\n- `src/phase_z2_pipeline.py:1947-2017` `_attempt_salvage_chain` (u8) + `:4451-4490` wiring (u9)\n- 6 pytest modules present under `tests/phase_z2/` (u10-u15)\n\nsource_comment_ids:\n- Claude #4 — Stage 5 commit-push Round #1 (proposer)\n- Codex #4 — Stage 5 commit-push Round #1 verifier (PASS)\n- This comment = Claude #5 Stage 6 final-close Round #1 analyzer\n\ncommit_sha: 56619a0239adc97b6ff4d46b009dd98a43e8e237\n", "assets": [], "created_at": "2026-05-18T02:13:28+09:00", "updated_at": "2026-05-18T02:13:28+09:00"}, {"id": 19031, "html_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12#issuecomment-19031", "pull_request_url": "", "issue_url": "https://gitea.hmac.kr/Kyeongmin/C.E.L_Slide_test2/issues/12", "user": {"id": 28, "login": "Kyeongmin", "login_name": "", "source_id": 0, "full_name": "이경민", "email": "kyeongmin@noreply.localhost", "avatar_url": "https://gitea.hmac.kr/avatars/d883a35f9197b080b2a0c535c3f9357dcd5c7d40b3c42bd8f40218cb94609a8e", "html_url": "https://gitea.hmac.kr/Kyeongmin", "language": "", "is_admin": false, "last_login": "0001-01-01T00:00:00Z", "created": "2025-12-30T10:51:04+09:00", "restricted": false, "active": false, "prohibit_login": false, "location": "", "website": "", "description": "", "visibility": "public", "followers_count": 0, "following_count": 0, "starred_repos_count": 1, "username": "Kyeongmin"}, "original_author": "", "original_author_id": 0, "body": "[Codex #5] Stage 6 final-close Round #1 verifier\n\nVerdict: PASS.\n\nI independently verified the Stage 5 commit and the Stage 6 close criteria against the binding exit reports.

CSS override checks show scoped `[data-role]` / `[data-zone-position]` outputs.\n\n=== EVIDENCE ===\nCommands run:\n- `Get-Content -LiteralPath 'D:\\ad-hoc\\kei\\design_agent\\.orchestrator\\tmp\\codex_prompt.txt'`\n- `git status --short`\n- `git log -1 --format=\"%H%n%P%n%s\"`\n- `git log --oneline a79bd8b..HEAD`\n- `git show --stat --oneline --decorate --no-renames HEAD`\n- `git diff-tree --no-commit-id --name-only -r HEAD`\n- `git ls-remote origin main`\n- `git ls-remote slide2 main`\n- `rg -n \"donors_used|aggregate_slack_used|aggregate_slack_available|plan_cross_zone_redistribute|apply_cross_zone_redistribute_css|plan_glue_compression|apply_glue_compression_css|plan_font_step_compression|apply_font_step_compression_css\" src/phase_z2_retry.py tests/phase_z2`\n- `rg -n \"cross_zone_redistribute|glue_compression|font_step_compression|SALVAGE_FAILURE_TYPE_BY_ACTION|NEXT_ACTION_BY_FAILURE|ACTION_IMPLEMENTATION_STATUS|NEXT_ACTION_IMPLEMENTATION_STATUS\" src/phase_z2_failure_router.py src/phase_z2_router.py tests/phase_z2/test_phase_z2_failure_router_cascade.py`\n- `rg -n \"def _attempt_salvage_chain|_attempt_salvage_chain\\(|salvage_steps|salvage_passed|_attempt_zone_ratio_retry\" src/phase_z2_pipeline.py tests/phase_z2/test_phase_z2_step17_salvage_chain.py`\n- `rg -n \"ACTION_BY_CATEGORY\" src/phase_z2_router.py`\n- `pytest -q tests/phase_z2/test_phase_z2_retry_multi_donor.py tests/phase_z2/test_phase_z2_cross_zone_redistribute.py tests/phase_z2/test_phase_z2_glue_compression.py tests/phase_z2/test_phase_z2_font_step_compression.py tests/phase_z2/test_phase_z2_failure_router_cascade.py tests/phase_z2/test_phase_z2_step17_salvage_chain.py`\n- `git diff a79bd8b..HEAD -- <IMP-12 committed files> | rg -n \"MDX 03|MDX 04|MDX 05|samples/mdx|sample_mdx|fallback_path|Kei|AI|LLM|openai|chat\"`\n- `rg -n \"fit_verifier|redistribute\\(|compute_glue_css_overrides|find_fitting_font_size|SPACING_GLUE|FONT_SIZE_STEPS|data-zone-position|data-role\" src/phase_z2_retry.py tests/phase_z2/test_phase_z2_cross_zone_redistribute.py tests/phase_z2/test_phase_z2_glue_compression.py tests/phase_z2/test_phase_z2_font_step_compression.py tests/phase_z2/test_phase_z2_step17_salvage_chain.py`\n- `git diff --stat a79bd8b..HEAD`\n\nFiles checked:\n- `D:\\ad-hoc\\kei\\design_agent\\.orchestrator\\tmp\\codex_prompt.txt`\n- `D:\\ad-hoc\\kei\\design_agent\\src\\phase_z2_retry.py`\n- `D:\\ad-hoc\\kei\\design_agent\\src\\phase_z2_failure_router.py`\n- `D:\\ad-hoc\\kei\\design_agent\\src\\phase_z2_router.py`\n- `D:\\ad-hoc\\kei\\design_agent\\src\\phase_z2_pipeline.py`\n- `D:\\ad-hoc\\kei\\design_agent\\tests\\phase_z2\\test_phase_z2_retry_multi_donor.py`\n- `D:\\ad-hoc\\kei\\design_agent\\tests\\phase_z2\\test_phase_z2_cross_zone_redistribute.py`\n- `D:\\ad-hoc\\kei\\design_agent\\tests\\phase_z2\\test_phase_z2_glue_compression.py`\n- `D:\\ad-hoc\\kei\\design_agent\\tests\\phase_z2\\test_phase_z2_font_step_compression.py`\n- `D:\\ad-hoc\\kei\\design_agent\\tests\\phase_z2\\test_phase_z2_failure_router_cascade.py`\n- `D:\\ad-hoc\\kei\\design_agent\\tests\\phase_z2\\test_phase_z2_step17_salvage_chain.py`\n\nTest results:\n- Targeted IMP-12 suite: `19 passed in 0.08s`.\n- Full pytest intentionally not run, per current-stage instruction not to run full pytest unless explicitly required.\n\nCommit SHA:\n- `56619a0239adc97b6ff4d46b009dd98a43e8e237`\n\nVerified facts:\n- HEAD parent is `a79bd8bc43d4a2d77c2a50005e3c07c8e56abf28`.\n- `a79bd8b..HEAD` contains exactly one commit.\n- Commit subject is `feat(IMP-12): Step 16/17 retry refinement - multi-donor + 3-stage salvage cascade`.\n- `origin/main` and `slide2/main` both resolve to `56619a0239adc97b6ff4d46b009dd98a43e8e237`.\n- Commit diff contains exactly 10 files: 4 scoped source files and 6 scoped test files.\n- Diff stat is 10 files, 1247 insertions, 40 deletions.\n- `donors_used`, `aggregate_slack_used`, and `aggregate_slack_available` are present in `plan_zone_ratio_retry` and covered by tests.\n- `cross_zone_redistribute`, `glue_compression`, and `font_step_compression` route through `NEXT_ACTION_BY_FAILURE` and are marked `IMPLEMENTED` in router/failure-router status maps.\n- `_attempt_salvage_chain` is present and wired after `_attempt_zone_ratio_retry` in `src/phase_z2_pipeline.py`.\n- Scoped CSS guardrails are represented by `[data-role=\"...\"]` and `[data-zone-position=\"...\"]` outputs and tests.\n- Untracked files remain outside the commit and were not included in IMP-12 scope.\n\nFINAL_CONSENSUS: YES", "assets": [], "created_at": "2026-05-18T02:15:36+09:00", "updated_at": "2026-05-18T02:15:36+09:00"}] |
