[Claude #1] Stage 1 problem-review — IMP-48 composition planner re-split on all-reject

The current Step 6 chain has FOUR settling paths for sections that have only reject V4 evidence:
phase_z_status ∉ MVP1_ALLOWED_STATUSES); reject-merged candidates dropped.allow_provisional=True+allow_provisional_fill=Trueso reject sections get a "provisional rank-1 V4Match" and survive into selected_units withlabel="reject",provisional=True.When the parent has direct V4 evidence (Branch 2
parent_merged) OR children agree on a representative (Branch 3parent_merged_inferred), a merged unit is created with the parent/representative's rank-1 V4 match. Two failure cases the issue targets:(a) Parent's / representative's rank-1 V4 label is
rejectAND the provisional retry path (u12 / u4) admitted the merged unit withlabel="reject", provisional=True. IMP-47B (#76) hands the whole merged blob to AI for restructure — but individual sections (S1 alone, S2 alone) might have non-reject rank-1 evidence that would have flowed through the normal path. The merge is the cause of all-reject, not the content.(b) parent_merged_inferred merge where representative
label=rejectsurvives the W1/W2/W3 weak filter via provisional path. Same pattern — split would unlock individual non-reject matches.The merge is upstream of frame matching; once merged, the frame_selection result for the merged shape is all-reject. The composition planner today has no mechanism to undo the merge after observing the all-reject outcome.
📌 Gap vs IMP-47B (#76) chain partner
1186ad8) activates AI re-construction over the rank-1 reject frame forreject + provisional=Trueunits. It assumes the unit shape is given (frame stays, AI re-arranges content).📌 Detection signal (deterministic)
A unit qualifies for re-split iff ALL of:
unit.merge_type ∈ {"parent_merged", "parent_merged_inferred"}(notsingle/cli_override/empty_shell).unit.label == "reject"(the merged shape's V4 rank-1 is reject — the all-reject signal at unit level since rank-1 = the strongest non-reject was already reject).len(unit.source_section_ids) >= 2.No look at Step 9 / Step 11 trace required — the merged unit's own
labelalready encodes "V4 rank-1 for merged shape = reject", which (by V4 construction) is the only way V4 admits a reject candidate at rank-1 (rank-1 is the best label).📌 Proposed scope-lock (Stage 2 plan target)
(S1) Insertion point:
src/phase_z2_pipeline.py:3967(after IMP-30 u4 retry / empty-shell block) → BEFORE Step 6 artifact write atsrc/phase_z2_pipeline.py:3976. Single hook, no recursion.(S2) New helper in
src/phase_z2_composition.py:resplit_all_reject_merges(units, sections, v4_lookup_fn, v4_label_to_status, allowed_statuses, capacity_fit_fn, v4_candidates_lookup_fn) -> tuple[list[CompositionUnit], dict].unitsfor the detection signal above.collect_candidatespath (Branch 1 only —merge_type="single") using each section's own V4 evidence. No new V4 lookups outside the existing fns.layout_presetviaselect_layout_preset(new_units).(S3) Re-split admission rule (no frame swap, no hardcoding):
v4_lookup_fn(sid)result (= that section's V4 rank-1). This is each section's own evidence — NOT a frame swap. Some new singles will be non-reject (use_as_is / light_edit / restructure) and flow normally; some will still be reject and route to IMP-47B (#76) per-section.(S4) Layout preset re-derivation safety:
resplit_skipped_reason="post_split_unit_count_exceeds_layout_max". IMP-47B handles the merged unit.(S5) max retry = 1, idempotent:
merge_type="single"excludes them from the detection signal next time anyway).(S6) Skip cases (carve-outs):
section_assignment_plan is not None(CLI /--override-section-assignmentsactive per IMP-06 / #6) → SKIP. User explicitly chose grouping; no auto re-split (matches scope: "이미 #6 IMP-06 구현").cli_override/empty_shell→ SKIP (not auto-planner merges).(S7) Step 6 artifact audit fields (additive, no schema break):
comp_debug["imp48_resplit"] = { applied: bool, split_units: [{merged_source_section_ids, replacement_unit_section_ids, reason}], skipped_units: [{source_section_ids, reason}], post_split_unit_count, post_split_layout_preset }.noteextended to mention IMP-48 resplit audit.📌 Guardrails (binding for Stage 2)

📌 Files affected (Stage 2 target)
src/phase_z2_composition.py— addresplit_all_reject_merges()helper (pure function over existingcollect_candidatesmachinery).src/phase_z2_pipeline.py— call helper at line ~3967 (after u4 retry/empty-shell block, before Step 6 artifact write). Plumb audit fields intocomp_debug["imp48_resplit"]and Step 6 artifact note.📌 Regression matrix (Stage 4 verify target)

provisionalflag is False butlabel=rejectmade it through via some unusual path), or only on units that came through u12 / u4 retry (provisional=True)? Current draft: ALL merged units withlabel=rejectregardless of provisional flag, because the underlying signal (V4 rank-1 = reject for merged shape) is the same. —stage_1_reviewif reviewer disagrees.stage_1_reviewif reviewer wants partial.selection_path="resplit_from_merge"for telemetry? Current draft: yes, add to CompositionUnit.selection_path (additive field reuse, no schema add). —stage_2_planfor the exact telemetry shape.📌 Stage 1 deliverables

[Codex #1] Stage 1 problem-review - IMP-48
Verification result: scope-lock YES, with one precision correction.
I agree with the root cause that merged composition units can hide a better per-section path and then hand the whole merged blob to the IMP-47B AI repair surface. The wording "Step 9 all reject" should not be treated as an independent post-Step-9 decision in the current code: Step 9 is passive/reporting and consumes the already-selected Step 6 units. The implementation hook should therefore sit after the relevant
plan_composition()result is available and before the Step 6 artifact/downstream render records are finalized.Verified root cause:

Replaced the u2 placeholder block at the end of

Also updated the docstring to describe the u3 slice and rewrote thedel allowed_statusescomment to reflect Stage 2 / Codex YES (threshold fixed tosingle.label != "reject").u3 slice scope (additive within the helper — no other file touched):
Per-merge decision pass — iterate

IMP-47B (#76) then handles the merged unit directly.b. Beneficial split (Stage 2 Q2 Codex YES — "≥1 section gains non-reject frame") — count rebuilt singles with
label != "reject". Ifnon_reject_count == 0→decision="skip"withreason="no_beneficial_split". Stage 1 contract phrasing ("non-reject rank-1") is preserved verbatim.c. Layout cap (cumulative ≤ 4) (Stage 2 Q2 default — keep merged, no partial split) — after per-merge decisions, project

Ifprojected > 4, flip EVERY would-be split todecision="skip"withreason="layout_cap_exceeded"and stashprojected_post_split_count. v0select_layout_preset(src/phase_z2_composition.py:773) only supports 1~4 units, so the cap matches the upstream constraint exactly.Order-stable swap — build

Split decisions extendout_unitswith their rebuilt singles insource_section_idsorder; skip decisions append the merged unit unchanged.Telemetry tag (Stage 1 Q3 YES — additive field reuse on

[Codex #6] Stage 3 code-edit review - IMP-48 u3
Verified the single executed unit
u3only.Result: correct for the
u3slice. The helper now makes the actual gating and replacement decision after the u2 rebuild attempts: it applies a split only when all child sections rebuild successfully, at least one rebuilt child haslabel != "reject", and the projected post-split unit count stays within the v0 layout cap of 4. Applied splits replace the merged unit in input order with per-section singles and tag those singles withselection_path="resplit_from_merge".No Stage 2 scope creep found. The change remains confined to

[Codex #8] Stage 3 code-edit review - IMP-48 u5
Verified the single executed unit
u5only.Result: correct for the
u5slice. The pipeline now re-deriveslayout_presetfrom theresplit_all_reject_merges()audit only when a split was actually applied and the user did not provide--override-layout. The Step 6composition_planartifact is extended additively withimp48_resplit, and the note documents the deterministic IMP-48 post-pass without changing Step 9, IMP-47B routing, Step 12 AI repair, or frame override behavior.No Stage 2 scope creep found. The re-derived preset comes from the helper's
post_split_layout_preset, which is computed withselect_layout_preset(out_units)after the helper's layout cap guard. The artifact write consumes the post-resplitunitslist and currentlayout_preset, soselected_units_count,layout_preset_decided,selected_units, anddebug.imp48_resplitstay aligned.=== EVIDENCE ===

Added a footer bullet "u8 split-help cases lock the mdx04 04-1 expectation" (Stage 1 issue body references mdx04 04-1 as the split-help reference sample — kept as English ASCII commentary, no MDX file path or sample name embedded in test logic).Pattern continuity with u7 (no regression):

src/touch, no schema add, no contract drift)._make_merged_unitfactory's defaultframe_id="MOCK_FRM_PARENT"(not"MOCK_FRM_PARENT_REJECT") is fine but caused a brief mid-write inconsistency in my Case 16 first draft — I corrected the assertion to derive frommerged.frame_template_id/merged.frame_iddynamically so the test stays robust against factory default drift.

[Codex #11] Stage 3 code-edit review - IMP-48 u8
Verified the single executed unit
u8only.Result: correct for the
u8slice. The additive tests intests/test_phase_z2_pipeline_imp48.pycover the split-help pipeline boundary contract: merged reject units are replaced by per-section singles when child rank-1 V4 evidence is non-reject, each split single carries its own V4 evidence and raw content, selection_path telemetry is applied only to split-produced singles, normal per-section Phase Z statuses are restored, section coverage and ordering are preserved, the post-split layout preset audit matchesselect_layout_preset(out_units), and the Step 6 serialized payload reflects the post-split singles rather than the merged parent.No Stage 2 scope creep found in the
u8test slice. The tests are synthetic and do not run the heavy pipeline, do not depend on real catalog templates or real MDX files, and do not touch Step 9, IMP-47B routing, Step 12 AI repair, or frame override behavior. The source hook remains positioned before the Step 6 artifact write, and the targeted test file passes.=== EVIDENCE ===

Pattern mirrors u8 (synthetic_StubV4Match/_StubSection+_serialize_units_like_step6_artifact+MOCK_prefix identifiers — ★ RULE_7_no_hardcoding) and reuses the existing_make_merged_unitfactory attests/test_phase_z2_pipeline_imp48.py:329-348(no duplicate helper introduced).Stage 2 u9 scope-lock: "Pipeline regression for split-then-reject case: coverage preserved and remaining reject singles remain eligible for IMP-47B handoff." Implementation invokes
resplit_all_reject_mergeswith the SAME call signature the pipeline forwards atphase_z2_pipeline.py:3980-3989and asserts the contract that u4 (call site) + u5 (re-derive + Step 6 artifact extension) rely on when a merged-reject unit has MIXED children (≥1 own-rank-1 reject + ≥1 own-rank-1 non-reject). The case differs from u8 (all-non-reject children) in that the post-split unit list contains BOTH auto-renderable singles AND IMP-47B-handoff-eligible reject singles — the IMP-48 win surfaces as per-section IMP-47B input (instead of one merged blob).Module docstring extended with cases 18–25 under a new "u9 cases" section. Existing u7+u8 docstring sections (cases 1–17) untouched. New file header switched from "u7+u8" to "u7+u8+u9" with the corresponding scope sentence.
8 new tests across the 7 split-then-reject axes Stage 2 enumerated + 1 supplementary case (cases 18–25, numbered after the u8 case 17 trailing):
Case 18 — Split applied with mixed reject + non-reject children (
test_split_applied_with_mixed_reject_and_non_reject_children):merged_reject(MOCK_S1, MOCK_S2)where MOCK_S1's OWN rank-1 =use_as_isand MOCK_S2's OWN rank-1 =reject(the section is genuinely hard even alone).audit["applied"] is True, 2 singles in source order, merged removed.audit["split_units"][0]["non_reject_count"] == 1(1 non-reject + 1 reject child).split_singlesrecords each child's resolved label:MOCK_S1.label == "use_as_is",MOCK_S2.label == "reject".audit["skipped_reason"]is POPPED on applied path (Stage 1 contract atsrc/phase_z2_composition.py:1260).Case 19 — Reject split single routes to IMP-47B handoff via fallback_candidate (

[Codex #12] Stage 3 code-edit review - IMP-48 u9
Verified the single executed unit
u9and the cumulative IMP-48 Stage 3 implementation state.Result: correct for the
u9slice, and all planned Stage 3 implementation units are now complete. The u9 additions intests/test_phase_z2_pipeline_imp48.pycover the split-then-reject pipeline boundary contract: a merged reject unit splits when at least one child has non-reject rank-1 V4 evidence, the remaining own-reject child is preserved as a per-sectionfallback_candidatesingle for IMP-47B handoff, all section coverage is preserved, reject singles use their own V4 evidence rather than the merged parent or sibling evidence,selection_path="resplit_from_merge"applies to reject singles too, raw content stays per-section, and the Step 6 serialized payload exposes per-section units rather than the merged parent.No Stage 2 scope creep found in the
u9test slice. The tests are synthetic, useMOCK_identifiers, do not depend on real MDX samples or catalog frames, and do not modify Step 9, IMP-47B routing, Step 12 AI repair, mapper behavior, or frame override behavior. The source hook remains one-shot, deterministic, after Step 6 settling and before the Step 6 artifact write, with section-assignment override skip and layout-preset re-derivation preserved.=== EVIDENCE ===

[Codex #15] Stage 3 code-edit verification - IMP-48 u9
Verified the current Stage 3 unit as u9 only. The u9 test block is present in
tests/test_phase_z2_pipeline_imp48.pyand covers split-then-reject behavior: mixed reject/non-reject children split into per-section singles, reject singles retainphase_z_status="fallback_candidate", all-reject children keep the merged unit viano_beneficial_split, coverage is preserved, own V4 evidence is used without frame swap,selection_path="resplit_from_merge"is applied, raw content is preserved, and the Step 6 artifact mirror shows per-section handoff.No implementation defect found in this unit. The focused IMP-48 suite passes 39/39. I did not run full pytest because the current Stage 3 instruction is to verify only the single unit executed in this turn.

Decision: PASS. I independently verified the IMP-48 implementation shape, focused tests, scoped regression result, and baseline isolation. The implementation matches the Stage 2 plan and does not require a rewind.
Verification summary:
79f9ea5c92. IMP-48 source diff is limited to src/phase_z2_composition.py (+338) and src/phase_z2_pipeline.py (+61); IMP-48 tests are present as untracked files.79f9ea5with the same local ambient fixtures (.env, data/frame_cache/.gitkeep, and the two local family HTML files) reproduces the same 6 non-IMP-48 failures. The baseline has 681 passed / 6 failed because the 39 new IMP-48 tests are not present there; active workspace = 681 baseline passes + 39 IMP-48 passes = 720 passes.The six scoped-regression failures are outside IMP-48:
