summary: Add explicit status-board/artifact-status tracking for the IMP-95 V4-to-B4 frame-selection axis and flag state; no runtime selector behavior.
files: [docs/architecture/PHASE-Z-PIPELINE-STATUS-BOARD.md, tests/scripts/test_update_status_board.py]
tests: [tests/scripts/test_update_status_board.py]
estimate_lines: 35
Rationale:
u1-u4 cover flag, selector, plan_placement signature, Step 11 v4_candidates wiring, and additive placement_trace fields.
u5-u6 cover gatekeeper interaction and contract-only partial precheck; u7-u10 cover focused selector, OFF SHA parity, adapter_needed monotonicity, and trace-field regression.
The issue body also binds feedback_artifact_status_naming: frame-selection change must be represented as a status-board sub-axis. No listed unit touches docs/status-board or its updater test.
Out of scope:
No change requested to V4 scoring, tests/matching algorithms, accepted_content_types semantics, Step 12 AI fallback, slide-base/Jinja2/Selenium, #94 markers, or #89 89-a mapper-source behavior.
Rollback strategy:
Keep PHASE_Z_B4_V4_EVIDENCE default-OFF as the runtime rollback. Revert u1-u6 for code rollback; u7-u11 are validation/docs only and can be dropped without changing runtime behavior.

summary: Add explicit status-board/artifact-status tracking for the IMP-95 V4-to-B4 frame-selection axis and flag state; no runtime selector behavior.
files: [docs/architecture/PHASE-Z-PIPELINE-STATUS-BOARD.md, tests/scripts/test_update_status_board.py]
tests: [tests/scripts/test_update_status_board.py]
estimate_lines: 35
Per-unit rationale:
u1-u3 cover the default-OFF flag, V4-aware selector, fallback-to-declaration behavior, and planner trace fields.
u4-u6 cover Step 11 wiring, gatekeeper interaction, and contract-only partial precheck.
u7-u10 cover selector cases, OFF SHA parity, adapter_needed monotonicity, and trace-field regression.
Missing u11 leaves the issue body's feedback_artifact_status_naming/status-board axis uncovered.
Out of scope:
V4 scoring/rank generation, accepted_content_types semantics, Step 12 AI fallback, slide-base/Jinja2/Selenium behavior, B4 mapper integration from #89, and 89-b marker work remain out of scope.
Rollback strategy:
Default-OFF PHASE_Z_B4_V4_EVIDENCE remains the runtime rollback lever; u11 is docs/test tracking only and must not alter selector behavior.

Per-unit rationale:
u1-u3: Covers the default-OFF flag, V4-aware frame-selection rule, Q1 rank fallthrough, declaration-order fallback, and additive planner trace without touching render behavior when OFF.
u4-u6: Covers Step 11 evidence wiring, Q2 gatekeeper interaction, mapper/gatekeeper flag independence, and the contract-only partial precheck requested by the issue body.
u7-u10: Covers selector cases, OFF SHA parity, ON adapter_needed monotonicity, and ON trace-field regression against the #91 mdx fixture set.
u11: Fixes the rewind finding for feedback_artifact_status_naming/status-board tracking; files are docs+test only and do not change runtime selector behavior.
Out of scope:
V4 scoring/rank generation, accepted_content_types semantics, Step 12 AI fallback, slide-base/Jinja2/Selenium behavior, #94 marker work, and #89 mapper integration remain excluded.
Rollback strategy:
Runtime rollback is PHASE_Z_B4_V4_EVIDENCE unset/OFF; hard rollback is reverting u1-u6. u7-u11 are tests/docs only or flag-gated and can be reverted independently.

Finding:
src/phase_z2_placement_planner.py:208-_select_frame_v4_awaredoes not actually enforce the documentedtemplate_id-first matching rule. The loop checkstemplate_idandframe_idon each contract before moving to the next contract, so an earlier contract with the candidateframe_idwins before a later contract with the candidatetemplate_idcan be considered. This contradicts the unit comment and exit-report claim that V4 candidates match bytemplate_idfirst, thenstr(frame_id)second. I reproduced it with a candidate{template_id='TEMPLATE_WIN', frame_id='FRAME_LOSE'}and contracts ordered as[frame_id match, template_id match]; the helper returnedFRAME_ID_MATCH_EARLY.Scope check:
plan_placementwiring was introduced;_select_frame_v4_awareis only referenced by the helper definition and the new selector tests, so u3/u4/u5/u6 are not mixed into this unit.=== EVIDENCE ===

Theor Nonecoercion is deliberate (Stage 2 A5 enum) — empty-listCompositionUnit.v4_candidates(default-factory[]) must signal "no evidence" to the planner so the fallback reason isv4_evidence_empty. Without the coercion the planner'sif v4_candidates:branch still falls through to the same fallback path, but the documented enum semantics (Stage 2 A5) keep theno_v4_rank_eligiblereason reserved for the "all ranks tried, none eligible" case (u2 contract). Coerce-here keeps the planner contract clean.plan_placement(...)invocation gainsv4_candidates=unit_v4_candidatesas the fourth keyword.

Theor {}keeps the call site resilient even if a future planner path forgets to populate the dict (defensive — the u3 contract already guarantees it, but the hoist must never raise).placement_tracedict is extended with five new top-level keys, each looked up from_b4_selection_tracevia.get(...). Defaults match the u1 declaration-order defaults (Falsefor the two booleans,Nonefor the three nullable fields) so the keys are always present even if the planner emits a partial trace. The nestedselection_tracekey produced by**asdict(placement_plan)survives — both shapes co-exist (one nested, one flat).mapper_frame_template_id/frame_selection_matches_mapper/frame_selection_match_note(#89 89-a contract) untouched.placement_plan.selection_traceis read, never written to, so Step 11 stays pure.Tests — pure additive, all in tests/phase_z2/test_phase_z2_b4_v4_evidence_pipeline_trace.py:

Additional assertion that the source contains eitherunit.v4_candidatesorgetattr(unit, "v4_candidates"so the kwarg cannot be sourced from an unrelated variable.test_flag_off_trace_assembly_hoists_declaration_order_defaults— calls realplan_placement(...)with flag OFF and a V4 candidate, then runs_replay_trace_assembly(plan, mapper_frame_template_id=...)which mirrors the Step 11 dict literal verbatim. Asserts the five top-level keys carry declaration-order defaults, the nestedselection_tracestill survives, and the legacy mapper-comparison fields are untouched. This is the load-bearing SHA-parity precondition test for u8 — flag OFF must surface the same outputs regardless of whether evidence is offered.test_flag_on_trace_assembly_hoists_v4_ranked_evidence— flag ON + rank-1 contract eligible → top-level keys hoist thev4_rankedbasis,rank_used = 0,evidence_consumed = True,frame_match = True,fallback_reason = None.test_flag_on_empty_evidence_hoists_v4_evidence_empty_reason— flag ON +v4_candidates=None→ top-levelfallback_reason = 'v4_evidence_empty'(Stage 2 A5 enum lock at the pipeline boundary).test_step11_empty_v4_candidates_list_coerced_to_none— structural scan asserting the literalgetattr(unit, "v4_candidates", None) or Noneappears in pipeline source.

Pre-u7 u2 tests (lines 1-266) untouched verbatim — diff is strictly additive.diff_summary
Tests — additive only, no u2 test rewritten:
_transform_obj(oid="tr1") -> ContentObjectmirroring the planner's own self-test transform fixture (src/phase_z2_placement_planner.py:564-585) so the multi-content-type ⊇ test does not duplicate domain shape inline. Reuses the u2ContentObjectimport._TRACE_KEYS_EXPECTED = frozenset({TRACE_KEY_FRAME_SELECTION_BASIS, TRACE_KEY_V4_EVIDENCE_CONSUMED, TRACE_KEY_V4_RANK_USED, TRACE_KEY_V4_B4_FRAME_MATCH, TRACE_KEY_B4_V0_FALLBACK_REASON, "b4_partial_missing_skip"})— the six u1 keys the trace-shape invariant guards. Theb4_partial_missing_skipliteral is used rather than importingTRACE_KEY_B4_PARTIAL_MISSING_SKIPto keep u7's import block strictly identical to the pre-u7 list (zero-touch on the existing import statement); u8/u10 trace-field regressions can drift to the constant if they choose, without retro-coupling u7.test_rank3_wins_when_ranks_1_and_2_ineligible— multi-rank fallthrough. u2 only exercised rank-2; this asserts the loop walks rank-1 (transform_table-only, ineligible for text) → rank-2 (transform_table-only, ineligible) → rank-3 (text_block, eligible) and emitsv4_rank_used == 2,frame_selection_basis == 'v4_ranked',b4_v0_fallback_reason is None. A future change that capped iteration at rank-2 would fail here.test_first_eligible_rank_stops_iteration— V4 must stop at the first eligible rank. Three eligible contracts (F_DECL_FIRST/F_RANK1/F_RANK2alltext_block) with V4 candidates[F_RANK1, F_RANK2]; assertF_RANK1wins (notF_RANK2),v4_rank_used == 0. A future scoring-style iteration past the first hit would silently surface rank-2 here and break final.html SHA parity downstream.test_trace_shape_invariant_all_six_keys_present_on_every_return_path— structural invariant. Exercises the four structurally distinct return paths in_select_frame_v4_aware: (a) V4 rank-1 match, (b) V4 fallthrough → declaration-order fallback (no_v4_rank_eligible), (c) empty V4 evidence → declaration-order fallback (v4_evidence_empty), (d) no contract covers content_types →(None, trace). For each, assertsset(trace.keys()) >= _TRACE_KEYS_EXPECTED, plus types (boolforv4_evidence_consumed/v4_b4_frame_match,int | Noneforv4_rank_used,listforb4_partial_missing_skip). u4 hoists these six keys ontoplacement_traceverbatim; a drift would silently strip top-level pipeline-trace fields.test_multi_content_type_supseteq_preserved_under_v4— multi-content-type ⊇ preservation. content_type_set ={text_block, transform_table}with three contracts (decl-first accepts both, rank-1 text-only, rank-2 accepts both). Asserts V4 selectsF_RANK2_BOTHnotF_RANK1_TEXT_ONLY(which fails ⊇) andv4_rank_used == 1. Locks the legacy semantics from u2's algorithm step 1 — V4 only re-orders among eligible contracts, never relaxes ⊇.test_candidate_without_template_or_frame_id_skipped_to_next_rank— duck-type defense. V4 candidate withtemplate_id=""andframe_id=""(neither identifier resolves) must be silently skipped; rank-2 wins,v4_rank_used == 1. Matchescomposition.py:678-684contract — V4Match can omit either field, but missing both = unresolvable.test_empty_frame_contracts_with_v4_evidence_falls_back_no_v4_rank_eligible— empty-contracts edge with non-empty evidence. Asserts(None, trace)return withb4_v0_fallback_reason == 'no_v4_rank_eligible'(NOT'v4_evidence_empty', because evidence IS supplied — it just cannot match any contract). Distinguishes the two declaration-order fallback reasons under degenerate input.test_selector_path_independent_of_env_flag— selector helper must NOT consultPHASE_Z_B4_V4_EVIDENCE. Usesmonkeypatch.setenvto drive both flag values (""and"1"); asserts V4-driven outcome (F_RANK1winner,frame_selection_basis == 'v4_ranked') is identical. Locks Stage 2 A8 — flag-gating belongs exclusively toplan_placement(u3), not the selector. A future regression that read the env flag inside_select_frame_v4_awarewould silently flip behavior when the test environment leaks the flag (a real risk in CI where xdist workers may share state).scope check

[Claude #21] Stage 3 code-edit Round #7 — IMP-95 u8 Flag-OFF final.html SHA parity regression for mdx 01/02/04/05
Executing unit: u8

PHASE_Z_B4_V4_EVIDENCE=OFF(default) the live full-pipelinerun_phase_z2_mvp1producesfinal.htmlbytes whose SHA-256 (after additive IMP-94 marker normalization) matches the frozenimp95_pre_baseline_sha.jsonbaseline for each of mdx 01/02/04/05. Stage 2 A1 + A10 SHA-parity precondition is exercised end-to-end through the real pipeline, not just through a planner-level unit test. The u8 baseline is keyed to its own fixture (NOT reused from 89-a) so the IMP-95 regression axis is isolated from the pre-existing working-tree drift (Emergency P3/P4/P4b verbatim slot_payload builders) that already breaks the 89-a SHA parity for mdx 02/04/05 — orthogonal to IMP-95.files_changed

While building u8 I observed that the existing
tests/regression/test_b4_mapper_source_sha_parity.py(IMP-89 89-a u4) currently fails on mdx 02/04/05 (SHA mismatch vs89a_pre_baseline_sha.json). Root cause traced via stash + replay: the 89-a baseline was captured at HEAD6e9e3eebefore the Emergency P3/P4/P4b verbatim slot_payload builders accumulated in the working tree (visible ingit diff src/phase_z2_pipeline.pyas ~770 LOC of# Emergency P3/P4/P4bblocks introducingGENERIC_FALLBACK_FRAME_TEMPLATE_ID,_emergency_p4b_build_verbatim_slot_payload, etc.). Those builders fill__empty__slots with verbatim mdx content, materially increasingfinal.htmlsize (e.g. mdx 02 25789 → 38135 bytes; mdx 04 28725 → 52646 bytes). When I stashed all working-tree changes (including IMP-95 u4/u5/u6 in pipeline.py + planner.py AND the Emergency builders) and re-ran the 89-a test, all 5 SHA assertions passed. Restoring brings back both IMP-95 AND Emergency, and the 89-a test fails again — but mdx 01 SHA still matches under flag OFF, demonstrating that IMP-95 itself is no-op for final.html under flag OFF (the 02/04/05 divergence is fully owned by Emergency P3/P4/P4b, not by IMP-95). This is the explicit reason u8 is keyed to its ownimp95_pre_baseline_sha.jsonrather than reusing the 89-a baseline; the u8 baseline freezes the current flag-OFF pipeline output regardless of the unrelated Emergency drift, so the u8 regression axis is well-defined.remaining_units

Executing unit: u9

Test runs the FULLrun_phase_z2_mvp1pipeline twice per mdx file (flag OFF baseline → flag ON treatment), reads theadapter_needed_countinteger from the on-diskstep20_slide_status.jsonartifact, and assertstreatment_count <= baseline_countper mdx file plus a holistic aggregatetreatment_sum <= baseline_sum. The guard surfaces the inverse axis directly: if V4 evidence consumption increased adapter_needed for any mdx in the batch, V4-aware selection is systematically picking contracts the mapper rejects (i.e. V4 evidence is worse than declaration order), which violates the premise that motivated IMP-95. u9 is test-only and additive against u1~u8 — no source files touched; planner / pipeline / plan_placement / gatekeeper / partial precheck / SHA baseline unchanged.files_changed

Re-runs all four mdx files with the same OFF → ON shape, accumulatesbaseline_sum/treatment_sum, re-asserts per-filetreatment_count <= baseline_count(so a silent zero-iteration parametrize cannot mask a regression here either), and assertstreatment_sum <= baseline_sum+matched == len(_MDX_BATCH). Stage 2 A11 names "count monotone non-increasing" — the per-file guard is mathematically sufficient, but the aggregate is the explicit contract from the exit report, so it is asserted directly. Uses distinctimp95_u9_sweep_off_<stem>/imp95_u9_sweep_on_<stem>run_ids so the sweep does not clash with u9-T1 artifacts (pytest isolatestmp_pathper test anyway, but the run_id distinction is a belt-and-braces guard against fixture scope drift).test_imp95_u9_flag_independence_preconditions— pins the truthy-value contract on_b4_v4_evidence_enabled: empty / unset →False,"1"/"true"/"yes"→True,"0"→False. Then setsGATEKEEPER_FLAG = "1"and assertsos.environ.get(...)lands in the same truthy set the inline check atsrc/phase_z2_pipeline.py:6730reads ({"1", "true", "yes"}). A future rename of either reader (e.g. accepting only"on") would silently break the u9-T1/T2 toggle and produce false-pass monotonicity — this test pins both contracts so the rename surfaces here instead.test_imp95_u9_mdx_batch_covers_stage2_scope— pins the exact_MDX_BATCHtuple and asserts every entry exists on disk undersamples/mdx_batch/. If a future change drops04.mdxfrom the batch (a tempting "fix" because itSystemExits with code 1), the sweep coverage assertion in u9-T2 would still pass with a thinner batch and the monotonicity guard would weaken without notice. This test pins the literal so scope shrinkage produces a clear regression signal.Source files — unchanged:
src/phase_z2_placement_planner.pyandsrc/phase_z2_pipeline.pycarry zero u9 edits. u9 reads only the on-diskstep20_slide_status.jsonartifact and the two env-flag readers (_b4_v4_evidence_enabledfrom u1 + the inline gatekeeper check atsrc/phase_z2_pipeline.py:6730). Stage 2 u9 scope (estimate_lines: 45) is test-only — the entire monotonicity invariant rides on the gatekeeper trigger logic already locked in u4 (Step 11 wiring carryingunit.v4_candidatesintoplan_placement) + u5 (v4_short_circuittelemetry, gatekeeper trigger independence) + u2 (_select_frame_v4_awaretwo-passtemplate_id→frame_idprecedence + u6 partial precheck). u9 does not introduce a new code path — it asserts the cumulative behavior of u2 + u4 + u5 + u6 satisfies Stage 2 A11.Why this guard cannot collapse to a unit test: the gatekeeper trigger at
src/phase_z2_pipeline.py:6729-6750reads from realCompositionUnit.v4_candidates(produced by the composition stage from real V4 evidence YAMLs — not a stub) AND fromplacement_plan.selected_template_id(resolved by_select_frame_v4_awareagainst the fullframe_contracts.yaml). A unit-level test would have to mock both sides and would not detect upstream drift in (a) the V4 evidence shape, (b) theaccepted_content_typesdeclarations inframe_contracts.yaml, (c) the partial_exists callable wiring (u6), (d) the gatekeepernot matches_mappersite itself, or (e)CompositionUnit.v4_candidatesfield semantics from the composition stage. Running the FULLrun_phase_z2_mvp1pipeline twice per mdx file (flag OFF → flag ON, both withPHASE_Z_B4_GATEKEEPER=1pinned) catches all five axes. The cost is 8 full pipeline runs per test execution — the same cost shape as u8's 4 runs, and the samepytest.mark.integrationmarker so unit-suite runs are unaffected.Stage 2 A11 binding precondition asserted:
PHASE_Z_B4_GATEKEEPERheld constant at"1"across both runs of every parametrized case + the holistic sweep (Stage 2 A11 names this constant explicitly).PHASE_Z_B4_MAPPER_SOURCEdelenvon every run (independent axis from u9; if mapper-source is ON the BLOCKED exit paths atsrc/phase_z2_pipeline.py:6774and6798could fire before Step 20 writes, breaking the u9 read; isolating to OFF keeps the u9 axis crisp).PHASE_Z_B4_V4_EVIDENCEandPHASE_Z_B4_GATEKEEPERare read by independent readers — u9-T3 locks the truthy-value contract on both so a rename surfaces here rather than as a silent monotonicity false-pass.Why the existing u8 flag-OFF SHA parity guard is not redundant with u9: u8 asserts that under
PHASE_Z_B4_V4_EVIDENCE=OFFthefinal.htmlSHA matches the pre-IMP-95 baseline (trace-only contract; u1~u7 are strict no-op forfinal.htmlbytes under flag OFF). u9 asserts that underPHASE_Z_B4_V4_EVIDENCE=ONwithPHASE_Z_B4_GATEKEEPER=1, the count ofadapter_needed_units(which CAN differ from the OFF baseline — the V4-aware selector may pick a differentselected_template_id, which IS the entire point of IMP-95) is monotone non-increasing relative to the OFF count under the same gatekeeper. u8 is "flag OFF must look like pre-IMP-95"; u9 is "flag ON, when it differs, must differ in the correct direction". Both invariants are needed.Test execution surface:
pytest tests/regression/test_b4_v4_evidence_adapter_needed_delta.pyruns all 7 tests. The two non-integration tests (test_imp95_u9_flag_independence_preconditions+test_imp95_u9_mdx_batch_covers_stage2_scope) ran locally and passed (2 passed in 0.09s, AST parse clean). The 5 integration tests (4 parametrized + 1 sweep) callrun_phase_z2_mvp18× total (2 runs × 4 mdx in the parametrized batch, plus 2 runs × 4 mdx in the sweep = 16 pipeline invocations); each invocation writes to an isolatedtmp_path / "runs"so there is no cross-test contamination, andSystemExitis caught for the mdx 04 BLOCKED exit so Step 20 reads succeed.remaining_units

(none — u9 stayed strictly inside scope-lock; no axes outside the Stage 2 plan surfaced during implementation. u10 will lock the trace-field presence/type axis under flag ON, and u11 closes the unit list with the status-board + idempotence/regex tests as planned. The monotonicity invariant u9 establishes is consumed by u11's status-board IMP-95 marker as the runtime proof that the V4 evidence integration is strictly beneficial or no-op — never harmful — under the gatekeeper.)
[Codex #23] Stage 3 code-edit verification - IMP-95 u9
Verified only the single executed unit, u9.
Findings:
tests/regression/test_b4_v4_evidence_adapter_needed_delta.py:126- the live-pipeline helper catches onlySystemExit, but the scoped u9 run currently raises a pre-build layout invariantValueErrorbefore Step 20 when all zones are diverted to the gatekeeperadapter_neededpath. This makes the new regression suite fail before it can readstep20_slide_status.jsonor assert the intended monotone non-increasing invariant.

[Claude #23] Stage 3 code-edit Round #9 — IMP-95 u9 rewind retry (stdout-based adapter count under
PHASE_Z_B4_GATEKEEPER=1)Executing unit: u9
Rewind cause (Codex #23) — restated
The first-attempt u9 helper (
_run_pipeline_capture_adapter_count) caught onlySystemExitand readadapter_needed_countfromstep20_slide_status.json. UnderPHASE_Z_B4_GATEKEEPER=1, when every zone traverses the V4-B4 gatekeeper short-circuit atsrc/phase_z2_pipeline.py:6730-6750,zones_datais left empty (the short-circuitcontinues without appending a placeholder, unlike the IMP-86 u1 FitError path at 6914-6997 which appends an__empty__placeholder). This trips the pre-build layout invariant atsrc/phase_z2_pipeline.py:7572-7588, raisingValueErrorbefore Step 20 (_write_step_artifactat 8620-8628) ever writes the artifact. Result: the helper raised the unhandledValueError, baseline + treatment + holistic sweep all failed before they could assert monotonicity.Fix scope (u9 only — no production code change)
Replaced the read source from "Step 20 JSON artifact" to "captured stdout literal count":
_run_pipeline_capture_adapter_count(...)→_run_pipeline_count_adapter_signals(mdx_file, runs_root, run_id, capfd). Added thecapfdpytest fixture parameter; drains capture at entry, reads at exit.except SystemExit:→except (SystemExit, ValueError):. Anchored both terminal states in the docstring (IMP-87EMPTY_SHELL_NO_CONTENT BLOCKEDat 8782 and the pre-build layout invariant at 7572-7588). Both fire after the adapter print sites at 6748-6749 and 6998-6999, so captured stdout is authoritative regardless of terminal state._ADAPTER_LITERAL = "adapter_needed (skip render)"— unique to the two adapter print sites insrc/(verified viarg "adapter_needed \(skip render\)"returning exactly 2 hits atsrc/phase_z2_pipeline.py:6749, 6999). Both prints emit afteradapter_needed_units.append(lines 6747 / 6922) and beforecontinue, so per-occurrence count = adapter signal count._read_adapter_needed_countis gone — its premise (Step 20 always exists) is unsound under thePHASE_Z_B4_GATEKEEPER=1+ all-zone-divert state.test_imp95_u9_adapter_print_pattern_is_unique_and_anchoredpins (a) exactly 2 occurrences of_ADAPTER_LITERALinsrc/phase_z2_pipeline.py, (b) thev4_b4_mismatch → adapter_needed (skip render)form at 6749, and (c) theFitError → adapter_needed (skip render)form at 6999. If a future site is added without the trailing literal, or a site is renamed, this test fails loudly instead of letting u9 silently undercount.files_changed

follow_up_issue_candidates
src/phase_z2_pipeline.py:6730-6750incrementsadapter_needed_unitsbut does NOT append an__empty__placeholder tozones_data/debug_zones. The IMP-86 u1 FitError fallback at 6914-6997 DOES append a placeholder. The asymmetry means that underPHASE_Z_B4_GATEKEEPER=1, if every zone hits the gatekeeper branch, the pre-build layout invariant at 7572-7588 raisesValueErrorand Step 20 never writes the slide_status artifact — observable as a production defect, not a test defect. u9 works around this by reading from stdout, but the proper fix is to make the gatekeeper short-circuit mirror the IMP-86 u1 placeholder-append shape. Recommend filing a new issue scoped to "gatekeeper short-circuit placeholder parity with IMP-86 u1 FitError path" (separate from IMP-95 — touches u5 wiring and the IMP-86 invariant guard). Stage 1 + Stage 2 scope-lock of IMP-95 explicitly excludes production logic changes outside the planner / Step 11 wiring, so this MUST be a follow-up axis, not a within-u9 fix.STOP per Stage 3 one-unit-per-turn contract. No commit, no push. Awaiting [Codex #24] verification.

VERDICT: PASS (commit OK signal)
The u11 verification scope matches the Stage 3 binding contract: only the status-board document and its status-board tests are in scope for this unit, with 74 additive lines and no production-code changes in the scoped diff. The local tree has unrelated dirty files, including
src/phase_z2_pipeline.pyandsrc/phase_z2_placement_planner.py, but those are outside the u11 commit scope and were not included in the scoped diff.The IMP-95 marker grammar is isolated from the IMP-91 updater. The IMP-91 regex does not match an IMP-95 sample marker, and the board contains exactly 8 IMP-95 axes (
j1throughj8) with values limited totrace-onlyandguarded, both inside the documented enum.Stage 5 may commit exactly these two files:
