[Claude #1] Stage 1 — IMP-34 problem review (overflow chain step 1 — zone resize + compact retry)
Root-cause framing
IMP-34 is the first deterministic step of the overflow remediation chain (Step 16 → 17). The chain shape (post-IMP-12) is:
Today,
plan_zone_ratio_retry(src/phase_z2_retry.py:43-215) selects donor zones by static contract slack only:slack = current_height_px − min_height_px(line 127). This is a contract signal — it says "how far can we shrink this zone before violating itsvisual_hints.min_height_px" — and ignores whether the zone actually has empty space rendered. A donor whoseclientHeight=200,min_height_px=120, but whose internal content already takesscrollHeight=195will be picked withslack=80, the plan will take 80 from it, and after rerender the donor itself overflows by195 − 120 = 75. The candidate fails visual_check, the orchestrator reverts (correct), and the cascade falls through tocross_zone_redistributeunnecessarily — burning a Selenium rerender on a donor we could have rejected up-front from data already inoverflow["zones"][i].The issue body reframes axis 7 of #44 (originally "frame_swap / popup escalation", corrected: frame_swap forbidden — V4 rank-1 protection) to zone resize. The concrete enhancement is: donor capacity must be bounded by measured empty space (
clientHeight − scrollHeight), not just static contract slack. The measured signal is already produced by the Selenium JS atsrc/phase_z2_pipeline.py:2305-2314and surfaced intooverflow["zones"][i]asclientHeight/scrollHeight/excess_y(line 2393 pushes the fullmdict) — it is read by_attempt_salvage_chainfor cross_zone_redistribute synthesis (src/phase_z2_pipeline.py:5117-5130) but is not read byplan_zone_ratio_retry.Verified facts (value + path + upstream)

failure_router.classify_retry_failuresubstring match → cascade misroutes to wrong branch. Mitigation: Stage 2 plan must spell out the exact failure_reason template (English:"primary donor … slack … target_added_px"substring preserved) + regression testtest_phase_z2_failure_router_cascade.pyalready exercises this. Rewind:stage_3_edit._overflow_cleanwithoutclientHeight) misclassify donor →pytest -q tests/phase_z2/red. Mitigation: G8 graceful-absence rule + Case C regression test. Rewind:stage_3_edit.no_donor_candidatesfor cases that previously succeeded. Correct behavior — the previous "success" was misleading (donor would have overflowed post-take), andno_donor_candidatesalready routes tocross_zone_redistribute(same asdonor_slack_insufficient, perfailure_router.py:95-96). No regression — just earlier cascade entry.

overflow["zones"][i]omitsclientHeight/scrollHeight(existing IMP-12 tests), should the donor logic (a) fall back to static-slack-only [recommended — preserves all IMP-12 tests as-is], (b) treat asmeasured_empty=0(strict — would require fixture edits to IMP-12 tests), or (c) emit a warning + use static slack? Recommend (a).src/phase_z2_retry.py:166). Should the aggregate sum the neweffective_slack(=min(measured_empty, static_slack)) per donor [recommended — matches semantic intent], or sum measured_empty separately and check both gates? Recommend singleeffective_slackaggregation.measured_empty_px,effective_slack_px. Plan-level addition:donor_candidates_considered[i]already exists. Suggest also adding plan-levelaggregate_effective_slack_availableparallel to existingaggregate_slack_available. Confirm naming.failure_router.classify_retry_failure(line 205-217) matches on"primary donor"AND"slack"AND"target_added_px". Preserved literal strings? Or do we want to switch to a structuredfailure_codefield (longer rewrite, separate axis)?

Brief per-unit rationale:
No per-unit rationale can be accepted because no implementation units were declared. The prose plan covers the donor-capacity idea, but Stage 2 requires concrete units before Stage 3.
Out-of-scope notes:
The stated scope remains planner-only in
src/phase_z2_retry.py; frame_swap, spacing shrink, glue/font compression, popup escalation, Step 14 schema changes, salvage-chain edits, and content dropping remain out of scope.Rollback strategy:
Stage 3 should be allowed only after a compact Stage 2 plan declares small units. The intended rollback surface is limited to reverting changes in

Brief per-unit rationale:
u1: Correct surface and bounded-donor direction: src/phase_z2_retry.py:107-111 keeps donor filter, and 121-127 is the static-slack-only capacity to bound. Scope is deterministic planner only.
u2: Correct regression surface and line budget. Existing file has only the three IMP-12 multi-donor tests, so the proposed measured-empty/fallback/telemetry cases belong here.
Out-of-scope notes: frame_swap/V4 rank-1 reselect, glue/font compression, details_popup, layout_adjust, cqh/responsive fit, Step 14 schema changes, salvage-chain behavior changes, AI calls, spacing shrink, and content dropping remain out of scope.

Rationale:
slack = height - min_h(static only). Read overflow_zone_status[pos] (in scope at 108, built 94-96) for clientHeight/scrollHeight; measured_empty_px = max(0, clientHeight-scrollHeight); slack = min(static_slack, measured_empty_px) when both numeric, else static.

summary: Bound donor capacity in plan_zone_ratio_retry by min(static_slack, max(0, clientHeight-scrollHeight)) when both measured fields are present; keep static slack fallback when fields are absent; add measured_empty_px and slack_bound_source telemetry to donor_candidates_considered.

tests: [tests/phase_z2/test_phase_z2_retry_measured_bound.py]

summary: Add focused regression coverage for absent measured fields, measured-empty less than static slack, measured-empty greater than or equal to static slack, measured-empty zero, donor filter preservation, and telemetry source fields.
files: [tests/phase_z2/test_phase_z2_retry_measured_bound.py]
tests: [tests/phase_z2/test_phase_z2_retry_measured_bound.py]
estimate_lines: 48
=== END_IMPLEMENTATION_UNITS ===
Rationale:
u1: ACCEPT. The scope is one planner file and one deterministic capacity-bound decision. It reuses Step 14 fields already present in overflow["zones"] with no schema change, preserves the existing donor eligibility filter, preserves greedy aggregation, and does not touch _attempt_zone_ratio_retry orchestration, frame selection, spacing, padding, gap, line-height, or content.
u2: ACCEPT. The planned tests cover the issue axes and guardrails: measured bound, static fallback, measured source reuse, unchanged donor filtering, no frame_swap/layout_adjust/popup/glue/font side effects, and no sample-specific branching. Unit size is within the limit: 1 file and 48 estimated lines.
Out-of-scope: frame_swap / V4 rank-1 reselection; glue_compression and font_step_compression; details_popup escalation; layout_adjust; Step 14 schema changes; _attempt_zone_ratio_retry orchestration at src/phase_z2_pipeline.py:2131-2291; _attempt_salvage_chain behavior at src/phase_z2_pipeline.py:2304-2376; AI redesign and any MDX-specific hardcoding.
Rollback strategy: Revert u1 with git checkout HEAD -- src/phase_z2_retry.py. Revert u2 by deleting tests/phase_z2/test_phase_z2_retry_measured_bound.py. The plan is additive to telemetry and keeps absent-measurement fallback, so existing tests that omit measured fields remain compatible.

[Codex #14] Stage 4 test-verify - IMP-34 R1
Verification result: PASS. I independently re-ran the focused and scoped regression checks and verified the diff against the Stage 2 binding contract.
Scope-qualified findings:
src/phase_z2_retry.pychanges only theplan_zone_ratio_retrydonor capacity block. The change reads existing Step 14 fieldsclientHeightandscrollHeight, computesmeasured_empty_px = max(0, int(clientHeight) - int(scrollHeight)), and bounds capacity withmin(static_slack, measured_empty_px)when both values are numeric and not bool.measured_empty_px is None,slack_bound_source == "static_fallback".overflowed/clipped_innerdonors are still skipped.slack <= 0gate remains after the bound, so measured-empty zero excludes a full donor.measured_empty_pxandslack_bound_source.Hardcoding check:
rgoversrc/phase_z2_retry.pyandtests/phase_z2/test_phase_z2_retry_measured_bound.pyfound the new production logic is generic field-based (clientHeight,scrollHeight,measured_empty_px,slack_bound_source).MDX|03|04|05hit in the scoped files is test documentation text naming the no-hardcoding guard; there is no production sample branch or frame-id literal in the changed planner block.src/phase_z2_retry.pyare outside this IMP-34 diff.Regression status:
5 passed in 0.02s.162 passed in 26.06s.pytest teststree because the current stage explicitly requires independent test re-run plus diff verification, and the prompt says not to run full pytest unless explicitly required.=== EVIDENCE ===
