Root cause
Problem statement (per issue body)
zone_ratio_retryis implemented. Other Step 16 router action labels are MISSING.IMP-12+ INSIGHT-MAP §3 axis registry propose three Salvage Candidates:redistribute+ glue + font compression (sourced from PHASE-Q-AUDIT §2.4 / §2.5).Current code paths (verified)

Verbatim Korean quote from doc.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.frame_internal_fit_candidateexecution contract / internal envelope undefined (the frame-contract envelope format itself is yet to be specified).§3 review subjects, not as automatic adoption. AI-isolation invariant + "audit verdict ≠ adoption decision" reaffirmed in the 2026-05-11 reclassification pass.Root cause + conflict
plan_zone_ratio_retryis single-donor only. When the primary donor's slack is insufficient, sibling donors could supply additional slack but the planner returns feasible=False.compute_glue_css_overridesshrinks the shared CSS vars--spacing-block/--spacing-inner/--container-padding(space_allocator.py:944-983), andfind_fitting_font_sizeshrinks 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.Key conclusion : Of the three Salvage Candidates, only zone-level multi-donor
redistributeis compatible with the active locks. Glue + font compression conflict directly with the locks → explicit reject from IMP-12 scope.Scope-lock (2 axes, refine-only)

If 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-contractdensity_envelopefield (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.Guardrails

Verdict: root cause is verified, with one scope-lock caveat.
Verified root cause:
src/phase_z2_retry.py:163-178explicitly uses oneprimary_donorand returnsfeasible=Falsewhen that donor slack is belowtarget_added_px; the failure reason says multi-donor aggregation is a future axis.src/phase_z2_pipeline.py:1780-1815locks retry budget to 1 and strict donor rules;src/phase_z2_pipeline.py:1845-1869callsplan_zone_ratio_retryand stops before rerender when the plan is infeasible.src/phase_z2_failure_router.py:121-136classifies the resulting failure text asdonor_slack_insufficient, andsrc/phase_z2_failure_router.py:61-65maps that tolayout_adjustonly as a next proposed action.Verified current action surface:

Stage 1 unresolved-question resolution (Stage 2 lock)
Q1 — multi-donor as label or internal extension?
→ Internal extension of
plan_zone_ratio_retry.ACTION_BY_CATEGORYstays at 8 entries.Rationale: donor selection is a planner concern, not a policy concern. No new label preserves
feedback_no_hardcoding+ Stage-1 lock against new density-style labels.Q2 — salvage chain: composite vs sequential actions?
→ Three sequential router-cascade actions (
cross_zone_redistribute→glue_compression→
font_step_compression), each withretry_budget = 1per action. Cascade is driven byphase_z2_failure_router.NEXT_ACTION_BY_FAILUREchain, NOT by composite call.Rationale: independent feasibility + revert + diagnostic artifact per step; matches existing
(b) revertpolicy; observable trace per action.Q3 — glue / font output target: CSS-time vs adapter?
→ Frame-scoped CSS override at rerender time (NEW helper emits
.slide [data-zone-position="<pos>"] { --spacing-inner: ...; --container-padding: ...; font-size: ...; }).NEVER touches global

Both routes via u3NEXT_ACTION_BY_FAILURE→cross_zone_redistribute, so the cascade is exactly the surface that u3 routing points at.

Cascade then routes onward to glue_compression. This is the intended fallback — see u8's diff_summary "graceful degrade when fit_analysis missing".

Unit 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

None — u13 stays within Stage 2 scope_lock. Observation:
font_step_compressionemits only afont-sizeoverride; if zones with table/text-grid frames need synchronized line-height adjustment to match the line-height assumption (font_size * 1.6), that would land as a new axis on IMP-12 or a fresh issue. Not a u13 blocker — the math infind_fitting_font_sizealready 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.[Codex #N] Stage 3 code-edit verifier Round #N - unit u13

Unit u13 is verified. The new test module exercises the required

Goal vs result
zone_ratio_retryinternal extension (u1) closes Stage 1 root cause (donor_slack_insufficient). End-to-end_attempt_salvage_chainorchestrator covers (a) cross_zone-pass, (b) cross_zone-fail+glue-pass, (c) all-fail-revert cases (u15).Step 16 router action 신설literally suggests newACTION_BY_CATEGORYlabels, but Stage 2 locked these as cascade-only actions (surfaced viaNEXT_ACTION_BY_FAILURE). This preserves Step 16's 8-row category surface (Stage 1 lock), avoids inventing per-failure category strings, and aligns withPHASE-Z-PIPELINE-OVERVIEW.md:333(nodensity_adjust_candidate-style labels). Defensible reduction, explicitly documented atsrc/phase_z2_router.py:68-70.frame_reselectbody,layout_adjustbody,details_popup_escalation,adapter_needed— Stage 1/2 carved these out.4. Follow-up candidates (from Stage 2 follow_up_candidates + verification)
min_height_pxpropagation into salvage feasibility.plan_glue_compressionandplan_font_step_compressioncurrently use frame envelope arithmetic only — framemin_height_pxhint (IMP-11 D-2) is not consulted. Likely a small follow-up issue ("salvage feasibility honors framemin_height_px").ACTION_BY_CATEGORYredesign 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.frame_reselectterminal action body. Cascade currently dead-ends atframe_reselect(PARTIAL) — IMP-05 pre-render fallback exists, post-render rerender trace-only. Separate IMP axis.5. Labels / milestone

결과보고서 — IMP-12 Step 16/17 retry 정밀화
1. 왜 필요했나
Phase Z Step 16/17의 retry/salvage는 기존
zone_ratio_retry만으로는 다양한 visual failure를 충분히 다루기 어렵다. Phase Q~Y에서 확인한 deterministic salvage 패턴을 normal path AI 호출 없이 Phase Z에 추가할 필요가 있었다.2. 보완하려 한 기능
Step 16 router/action status와 Step 17 실행 path를 확장해
cross_zone_redistribute,glue_compression,font_step_compression순서의 deterministic salvage cascade를 제공하려 했다.3. 실제 변경 사항
src/phase_z2_retry.py에 다음 plan/apply pair를 추가했다:plan_cross_zone_redistribute/apply_cross_zone_redistribute_cssplan_glue_compression/apply_glue_compression_cssplan_font_step_compression/apply_font_step_compression_csssrc/phase_z2_failure_router.py에 cascade failure/action mapping을 추가했다.src/phase_z2_router.py의 action implementation status에 cascade actions를IMPLEMENTED로 등록했다.src/phase_z2_pipeline.py에_attempt_salvage_chain을 추가하고_attempt_zone_ratio_retry이후에 실행하도록 연결했다.4. 검증 결과
56619a0 feat(IMP-12): Step 16/17 retry refinement — multi-donor + 3-stage salvage cascade.redistribute,glue,font compression각각 feasible/infeasible path 테스트 추가.5. 남긴 것 / 넘긴 것
frame_reselect는 IMP-05의 pre-render rank-2/3 fallback 상태를 유지하며 terminal/partial 영역으로 남겼다. #12는 deterministic salvage cascade를 Step 16/17에 추가한 것으로 close했다.결과보고서 v2 — 슬라이드가 넘칠 때 자동 보정하는 기능 보강
한 줄 요약
생성된 슬라이드에서 내용이 넘치거나 맞지 않을 때, 여러 단계의 자동 보정 전략을 순서대로 시도하도록 했다.
왜 필요했나
자동 생성 슬라이드는 내용량이 많거나 특정 영역에 몰리면 넘칠 수 있다. 기존에는 일부 영역 비율 조정만으로 대응했기 때문에, 문제 유형에 따라 충분히 복구하지 못하는 경우가 있었다.
사용자가 매번 수동으로 고치기 전에, 시스템이 deterministic한 방식으로 먼저 보정해 볼 필요가 있었다.
무엇을 보완했나
세 가지 보정 전략을 추가했다.
이 전략들을 순서대로 시도하고, 실패하면 이전 상태로 되돌리는 cascade 흐름을 만들었다.
사용자가 얻는 효과
슬라이드가 조금 넘치거나 균형이 안 맞을 때 자동으로 복구될 가능성이 높아졌다. 실패하더라도 어떤 보정이 시도되었고 어디서 실패했는지 추적할 수 있다.
안전장치와 검증
AI나 외부 생성 호출을 추가하지 않았다. 모두 deterministic한 CSS/배치 보정이다. 각 보정 전략의 성공/실패 케이스와 전체 cascade를 테스트했다.
남은 한계 / 후속 작업
프레임 자체를 다시 고르는 더 큰 reselect 흐름은 별도 영역으로 남았다. 이번 작업은 생성 후 salvage cascade에 집중했다.
