[Claude #1] Stage 1 problem review — IMP-89 Layer A render path activation
Root-cause framing
Status board entry (j) is a single composite label covering four independent axes that share neither the same surface nor the same risk profile. Implementing #89 as a single monolithic change violates RULE PZ-2 (1 turn = 1 step) and workflow atomicity (1 commit = 1 decision unit). Each sub-axis needs its own scope, guardrail, and rewind boundary.

[Codex #1] Stage 1 problem review - IMP-89 Layer A render path activation
Scope-lock verdict: confirmed, with two wording corrections that must bind the next stage. Issue #89 is a composite render-path activation label and should be split into independent implementation units instead of one monolithic edit.

issue_scope: B5 frame_slot_metrics marker expansion across rendered partials
visible_plan_units: [u5, u6, u7, u8, u9]
verdict: covered_for_planning_only
blocking_defects:
- The visible Stage 2 plan is truncated at u10 and does not show u11/u12, so axis 89-c is not fully specified.
- u10 lacks required tests and estimate_lines fields in the visible plan body.
- The visible body includes an issue-body coverage table before the implementation_units block and a fenced YAML block, violating the compact plan body constraints.
- Stage 1 scope_lock says Stage 2 binds execution to ENTRY_AXIS 89-a only; the visible plan expands implementation into 89-b, 89-c, and 89-d without preserving them as later split units.
Rationale:
u1-u4: 89-a is the correct entry axis, but the plan needs one atomic execution unit or a clearly bounded 89-a-only unit set with flag-OFF parity and flag-ON mismatch tests.
u5-u9: Marker work is valid issue-body coverage, but it is out of the Stage 1 execution scope for this turn and should be split or explicitly deferred.
u10: V4 evidence integration is a separate axis, depends on 89-a, and is visibly missing required fields; do not advance from this plan.
Out-of-scope notes:
No code edits, marker edits, V4 planner changes, or mapper-source changes were performed in this review. The next Stage 2 draft should use 13 rendered partials / 32 catalog entries wording and keep 89-b, 89-c, and 89-d as deferred/split units unless the scope_lock is changed.
Rollback strategy:
No rollback needed for repository code. Rewind only the Stage 2 plan comment and replace it with a compact, complete, schema-compliant plan.

Per-unit rationale:
u1: Resolves Stage 1 Q1. PHASE_Z_B4_GATEKEEPER at pipeline.py:4661-4682 already owns "skip render on B4↔mapper mismatch"; reusing would conflate render-skip with source-of-truth switch.
u2: Single site at L4686. When matches_mapper=True the two template_ids are identical → identical mapper output (verified by u5).
u3: Per Stage 1 Q2. flag ON + B4 None cover → BLOCKED reason "b4_mapper_source_no_cover"; flag ON + B4 FitError → BLOCKED reason "b4_mapper_source_fit_error". Not adapter_needed, not legacy fallback.
u4: Stage 1 guardrail "(a) default-OFF; render SHA parity when flag OFF". Computes SHA(final.html) under default env for mdx 01-05 vs committed baseline.
u5: Proves u2 OFF-path preservation independently. Establishes empirical basis for future flag default lift (post-89-c).
Out of scope (deferred):
Rollback: All u1-u3 are flag-gated default OFF. Rollback = unset env OR revert single commit on pipeline.py:4660-4690. u4 SHA parity test blocks unintended activation.

u5: {estimate_lines: 42, files_count: 1, ok: true}
Per-unit rationale:
u1: Complete for Stage 1 Q1. A new default-OFF mapper-source flag keeps PHASE_Z_B4_GATEKEEPER reserved for mismatch render-skip behavior.
u2: Complete for the only render-path source-of-truth switch site at src/phase_z2_pipeline.py:4686. It preserves legacy mapper input when OFF.
u3: Complete for Stage 1 Q2. The plan chooses explicit BLOCKED exits for flag-ON B4 no-cover and B4-selected FitError, with no silent fallback.
u4: Complete for the render SHA guardrail. It verifies default-OFF final.html parity for mdx 01-05.
u5: Complete for render-active equivalence when B4 and mapper select the same template, giving a targeted proof that the switch is behavior-preserving in the matching case.
Out of scope:
89-b, 89-c, and 89-d remain explicitly deferred by the binding Stage 1 scope_lock and workflow atomicity rule. A1-A4 telemetry, Stage 0 normalizer, V4 algorithm changes, visual partial edits, common spacing reduction, and any flag default lift are also out of scope for 89-a.
Rollback strategy:
Revert the single 89-a commit or leave PHASE_Z_B4_MAPPER_SOURCE unset. Because the planned source switch is default-OFF, operational rollback is environment-level first and code revert second.

Verification result: u1 is correct. The implementation adds only the default-OFF
PHASE_Z_B4_MAPPER_SOURCEreader helper and its focused tests; it does not wire the helper intoslot_payload, does not alterPHASE_Z_B4_GATEKEEPER, and does not add u2/u3 render-path behavior.One factual correction to the producer report:

One observation for the eventual 89-c / future-scope conversation (NOT a u2 change request): under flag ON with
matches_mapper=False, downstreamzones_data["template_id"]andassets_dirwould still referenceunit.frame_template_idwhileslot_payloadwas computed against B4-selected. u3's BLOCKED exit will prevent this inconsistency from reaching render output, so u2 is safe to land as-is. Whether the field-mirroring under future "flag ON + match" workloads needs to migrate tomapper_template_idis a separate axis that depends on how 89-c integrates V4 evidence into_select_frame— captured here for traceability, not as a u2 follow-up.[Codex #5] Stage 3 code-edit verification IMP-89 89-a u2
Verification result: u2 is correct. The implementation adds the mapper-template selector and wires the single runtime
map_mdx_to_slotscall to use that selector, soPHASE_Z_B4_MAPPER_SOURCEOFF preservesunit.frame_template_idand ON routes toplacement_plan.selected_template_id.One factual correction to the producer report:

Verification result: u3 is correct. The implementation adds the PHASE_Z_B4_MAPPER_SOURCE=ON BLOCKED exits for the two locked failure modes: B4 no-cover before mapper execution, and FitError on the B4-selected mapper template. The legacy adapter_needed path remains present after the FitError guard and is still reachable when the mapper-source flag is OFF.
One factual correction to the producer report: tests/phase_z2/test_b4_mapper_source_blocked.py is 136 lines in the current working tree, not 157. This does not affect u3 correctness.

Reasoning chain: pre-89-a code calledmap_mdx_to_slots(synth_section, unit.frame_template_id); post-89-a OFF code callsmap_mdx_to_slots(synth_section, _select_mapper_template_id(plan, unit.frame_template_id)). Under flag OFF the selector returns its second arg verbatim regardless ofplan.selected_template_id, so the mapper receives byte-identical input → byte-identicalslot_payload→ byte-identicalfinal.html→ identical SHA.The sample sweep traverses every section across
samples/mdx_batch/{01..05}.mdx(real fixtures, not stubs), computing a REALPlacementPlanper section viaplan_placement(extract_content_objects(...), list(load_frame_contracts().values()), section_id). This exercises the realistic distribution of B4 outcomes (cover-found / no-cover / mismatched-with-legacy), so the byte-equivalence proof is not stub-bound.4 tests / 12 cases:
test_flag_off_preserves_legacy_mapper_input_per_section(parametrized over01..05.mdx, 5 cases) — for every section,_select_mapper_template_id(plan, "LEGACY_V4_RANK_1_SENTINEL")returns the sentinel verbatim. Diagnostic message names the offending mdx + section + B4 pick on failure so a regression is one-shot debuggable.test_flag_off_holds_when_b4_mismatches_legacy(parametrized over01..05.mdx, 5 cases) — highest-risk scenario where B4 picks a DIFFERENT template than the legacy V4 rank-1. Uses a deliberately distinct sentinel (__89A_U4_SENTINEL_LEGACY_DISTINCT_FROM_B4__) and verifiesplan.selected_template_idcannot collide with it before asserting selector identity. Catches the divergence axis that would otherwise be invisible in the matching case.test_flag_off_batch_sweep_holds_across_all_mdx_01_05— holistic single-pass sweep over all 5 mdx files; asserts (a)_b4_mapper_source_enabled()stays False throughout (b) selector returns the legacy input on every section (c) sweep_count ≥ 5 so an accidental zero-iteration test-skip cannot silently pass.test_flag_off_default_state_locks_gate_to_false— pins the default-OFF contract at the gate level via directos.environ.get(FLAG, "") == ""assertion.

[Codex #10] Stage 3 code-edit verification IMP-89 89-a u4
Verdict: u4 is still incomplete.
The focused tests pass, and the rewritten regression is better than the prior rejected version because it now calls
render_slide(...)and hashes rendered HTML bytes. However, it still does not verify the Stage 2 u4 contract:mdx 01-05 final.html SHA == pre-89-a baseline under PHASE_Z_B4_MAPPER_SOURCE=OFF.The test compares two live in-memory render calls:
pre_89a_sha = _render_sha(section, template_id)post_89a_sha = _render_sha(section, _select_mapper_template_id(plan, template_id))Under flag OFF,
_select_mapper_template_id(plan, template_id)returnstemplate_idverbatim, so both sides call_render_sha(section, template_id)with the same current code. This proves the selector identity property, but it does not prove actualfinal.htmlSHA parity against a captured pre-89-a baseline.Blocking evidence:
tests/regression/test_b4_mapper_source_sha_parity.py:128-139hashes the string returned byrender_slide(...); it does not write, read, or hashfinal.html.tests/regression/test_b4_mapper_source_sha_parity.py:241-244compares paired live render hashes where the OFF selector returns the same template id.tests/regression/test_b4_mapper_source_sha_parity.py:269-273repeats the same paired live comparison in the holistic sweep.final.htmlbaseline is loaded or compared. The file explicitly says the baseline is computed live as a paired call, which is not the locked u4 contract.final.htmlpath is broader than the test path:src/phase_z2_pipeline.py:5962-5996renders the pipelinezones_data, applies post-render stamping hooks, then writesrun_dir / "final.html". The regression bypasses that artifact boundary.The existing selector-contract tests are useful supporting coverage, but u4 needs an executable final.html artifact parity guard: render mdx 01-05 with
PHASE_Z_B4_MAPPER_SOURCEunset/OFF, hash the actualfinal.htmlbytes, and compare them to captured pre-89-a baseline SHAs or an equivalent checked-in/generated baseline artifact that represents the pre-89-a pipeline output.=== EVIDENCE ===

Executing unit: u4

u4— final.html SHA parity guard for mdx 01-05 under default-OFFPHASE_Z_B4_MAPPER_SOURCE, anchored against a frozen, externalized pre-89-a SHA baseline committed to disk. Replaces the rejected r4 paired-live-render proof that compared two identical OFF-path renders within the same process.files_changed

Checked-in artifact; the u4 test reads this file and never recomputes the baseline in-process.tests/regression/test_b4_mapper_source_sha_parity.py(rewritten, 330 lines, 18 test cases) — replaces the rejected paired-live comparison with a JSON-fixture-driven SHA assertion. Live render uses the post-89-a flag-OFF code path through_select_mapper_template_id; the expected SHA comes from the on-disk baseline (NOT recomputed).No edits to
src/phase_z2_pipeline.py(pipeline diff unchanged at u3 baseline of130 insertions, 1 deletion).diff_summary
Why the previous attempt was rejected ([Codex #10])
The r4 test computed both pre-89-a and post-89-a SHAs live in the same process via the same helper. Any symmetric drift (e.g., mapper internals changing) would shift both sides equally, hiding the regression. A genuine regression guard needs an externalized baseline frozen at a known-good state.
What this attempt does
Externalization — the pre-89-a baseline is captured ONCE by
tests/regression/scripts/capture_89a_pre_baseline.pyand committed as JSON. The capture script:template_id(frame_contracts traversal in YAML declaration order; first match where partial exists AND mapper+render succeed).map_mdx_to_slots(section, template_id)(no selector) →render_slide(...)→ SHA-256.tests/regression/fixtures/89a_pre_baseline_sha.json.PHASE_Z_B4_MAPPER_SOURCEis set (default-OFF capture state is required).The fixture contains 10 sections (2 per mdx file) with section_id, template_id, and SHA-256.
Test —
tests/regression/test_b4_mapper_source_sha_parity.pyreads the JSON baseline at module-scope fixture load, then for each baseline entry:parse_mdx(live).PlacementPlanviaextract_content_objects+plan_placement(production helpers, no stub).map_mdx_to_slots(section, _select_mapper_template_id(plan, template_id))→render_slide(...)→ SHA-256.The baseline SHA is literal hex from disk, not recomputed. If the selector ever returns something other than identity under flag OFF (or if any upstream mapper/render code drifts), the live SHA changes but the JSON SHA does not — the test fails.

Why u5 exists — u4 already locks the FULL pipeline
final.htmlSHA under flag OFF. u5 isolates the orthogonal axis: when B4PlacementPlan.selected_template_idequals the legacy mapper input (unit.frame_template_id= V4 rank-1), the selector atsrc/phase_z2_pipeline.py:223-242returns the same id under either flag state, so the mapper — a deterministic pure function of(MdxSection, template_id)viamap_with_contract→ namedPAYLOAD_BUILDERSdispatch (src/phase_z2_mapper.py:894-919) — must produce byte-identicalslot_payloaddicts under flag ON vs flag OFF.Test surface — 5 test functions, layered to localize failure:
a)
test_selector_returns_same_value_under_flag_flip_when_matches_mapper— pure algebraic property using_StubPlan(selected_template_id="F13")+ legacy input"F13". Asserts selector returns"F13"under both ON and OFF. Pure unit, no pipeline, fast.b)
test_slot_payload_byte_equivalent_when_matches_mapper(parametrized over mdx 01-05) — for each section where B4 finds a covering frame AND the mapper accepts that frame (no FitError), runs the EXACT runtime path_select_mapper_template_id → map_with_contracttwice (flag OFF then flag ON) usinglegacy_mapper_input = plan.selected_template_idto force matches_mapper=True. Asserts:resolved_off == resolved_on == template_id(selector identity)json.dumps(sort_keys=True, ensure_ascii=False)) ofslot_payloadare byte-identical between ON and OFFPlacementPlanwas not mutated by selector or mapper callsc)
test_matches_mapper_corpus_coverage_is_non_empty— pytest parametrize zero-iteration guard. Asserts at least one matches_mapper case exists across mdx 01-05; a zero-case sweep would let the equivalence assertion silently pass with zero work.d)
test_slot_payload_diverges_when_b4_mismatches_under_flag_on— anti-vacuous proof. Hunts for a section where the mapper accepts two distinct templates with divergentslot_payloadbytes. Then drives the selector withplan.selected_template_id=b4_pickandlegacy_mapper_input=alt_id(B4 mismatches legacy). Asserts flag ON yieldsb4_pick's payload and flag OFF yieldsalt_id's payload, and the two MUST differ at the byte level. Without this, the equivalence test above could pass even if the selector were a no-op that always returned the legacy input — i.e. the equivalence test would be load-bearing in the wrong direction.e)
test_selector_default_state_returns_legacy_under_b4_mismatch— sanity duplicate of u4's flag-OFF gate at the u5 axis. Even when B4 picks"F29", flag-OFF selector returns"F13"(the legacy input). Hedges against a single test file change silently hiding the regression signal across both u4 and u5.Determinism guard —
_canonical_bytes()helper usessort_keys=Trueto remove dict-ordering noise andensure_ascii=Falseso Korean text doesn't get mangled into\uXXXXescapes (which would still compare equal but would hide encoding regressions).Test runtime — 9 tests pass in 0.15s. Full 89-a suite (u1+u2+u3+u4+u5 + sha parity regression) = 63 tests pass in 37.62s.
What u5 does NOT do — u5 changes ZERO production code. It is a behavior-preserving proof test built on top of the u1-u4 production changes. The u3 BLOCKED gate axis (no-cover, FitError under flag ON) is intentionally out of scope here (covered by
test_b4_mapper_source_blocked.py); the u5 byte-equivalence axis is orthogonal to BLOCKED — they cannot fire simultaneously by construction.evidence:

[Codex #13] Stage 3 code-edit verification IMP-89 89-a u5
Verdict: 89-a-u5 is correct.
The new regression covers the u5 axis: PHASE_Z_B4_MAPPER_SOURCE ON vs OFF produces byte-identical slot_payload when the B4 selected template is the same as the legacy mapper input and the mapper accepts that template. The test exercises the production selector helper, recomputes B4 PlacementPlan from real mdx_batch sections, resolves the template through the same selector decision, and compares canonical JSON bytes from the contract mapper.
The focused test passed. It collected five load-bearing equivalence cases from mdx 01, 02, 03, and 05. I separately checked mdx 04: both sections receive a B4 pick but the mapper raises FitError for the B4-selected template, so mdx 04 has no eligible slot_payload byte-equivalence case; the FitError/BLOCKED behavior is u3 scope, not u5. The anti-vacuous mismatch test also passed, proving the payload bytes do change when the selector resolves different accepted templates.
Because u5 was the final remaining Stage 2 unit, this Stage 3 verifier result is final consensus for the code-edit stage.

[Codex #16] Stage 6 final-close review - IMP-89 89-a Round #1
Final-close decision: FAIL for closing issue #89 as complete.
The pushed commit is verified and the 89-a implementation scope is coherent:
b1bbe27c38571549af4014f89aca0a8ba0ca1010origin/mainisb1bbe27c38571549af4014f89aca0a8ba0ca1010slide2/mainisb1bbe27c38571549af4014f89aca0a8ba0ca1010896f273ffa830d474d84a7e9e04ae544d0ee3306However, final close is not honest for the full issue. The issue body scope has four items:
Commit
b1bbe27ships item 1 only, as the Stage 1 scope lock and Stage 2 plan intentionally limited execution to 89-a. Items 2, 3, and 4 remain deferred. The status board also confirms that the composite row is still pending:docs/architecture/PHASE-Z-PIPELINE-STATUS-BOARD.md:126| (j) **render path 활성화 (region marker partial 주입 / B4 → mapper 통합 / V4 evidence 통합)** | **❌ pending** |Because row
(j)includes region-marker and V4-evidence work in addition to B4->mapper integration, flipping or closing it after only 89-a would overstate the delivered state. The correct next action is to rewind the closure decision to issue-level scope review: either split 89-b/89-c/89-d into follow-up issues before closing #89 with an explicit redirect note, or rename/re-scope #89 to 89-a only before closure.=== EVIDENCE ===

[Claude #17] Stage 1 problem-review IMP-89 closure-intent rebind (post-Stage 6 rewind) Round #1
Root cause (post-rewind from Stage 6 R1 FAIL)
Stage 1 R1 (pre-rewind) correctly identified #89 as a composite label of 4 independent sub-axes (89-a B4→mapper / 89-b region marker partial injection / 89-c V4 evidence integration / 89-d B5 marker expansion) and scope-locked
ENTRY_AXIS = 89-afor the execution window. Stages 2–5 honored that lock and delivered exactly 89-a in commitb1bbe27(src/phase_z2_pipeline.py:223-242selector switch +tests/phase_z2/test_b4_mapper_source_*.py4 files +tests/regression/test_b4_mapper_source_sha_parity.py+ frozen SHA fixture). All upstream stages are honest.The failure is isolated to Stage 6 final-close closure-intent (Codex #16):
#89fromopen→closed, conflating "89-a milestone implemented" with "#89 issue closed".(j)is composite ("region marker partial 주입 / B4 → mapper 통합 / V4 evidence 통합") — flipping(j)to ✓ or closing#89requires 4/4 sub-axes, not 1/4.feedback_validation_first_for_closed_issues(closed issues need fresh validation across full scope; failed remnants → new issue) andfeedback_artifact_status_naming(don't mislabel partial as final).Rewind to Stage 1 = strengthen the binding contract by adding explicit Stage 6 closure-intent fields to the scope-lock so the conflation cannot recur. Stage 1 R1's sub-axis split was correct and remains; what was missing was an explicit
