[Claude #1] Stage 1 — IMP-43 problem review (incremental rerun
--reuse-from <prev_run_id>)Root-cause framing
IMP-43 (Gitea #72) proposes a
--reuse-from <prev_run_id>CLI flag so a frame-override-only iteration can copy the prior run's Step 0–8 artifacts and re-execute only from Step 9. The issue body claims 50–70% wall-clock savings (10–20s → 3–8s) and quotes the reuse boundary asstep00–step08 reuse, step09 부터 재실행.Walking the pipeline (
src/phase_z2_pipeline.py:4278–7117, the monolithicrun_phase_z2_mvp1) against this premise reveals that the asserted boundary is off, and the asserted savings are conditional on a path that is explicitly out of scope (Step 12 AI repair cache → IMP-46). The actual reuse-eligible artifacts under pure--override-frameare a smaller, non-contiguous subset of Steps 0–8 (specifically Step 0, 1, 2, 5, 6), and skipping them saves <1s on a default run dominated by Selenium (Step 14). For the issue's 50–70% savings target to be reachable from--reuse-fromalone, the pipeline architecture itself would need to change (Step 14 Selenium is unavoidable when the rendered HTML differs; AI repair cache is the other large saving and is explicitly deferred to IMP-46).This Stage 1 surfaces those gaps so Stage 2 can scope the issue against the actual reuse boundary + measured cost distribution + the architectural constraint, rather than implementing to the issue body's idealized framing.

Reusing Step 3, 4, 7, 8 from a prior run would diverge from a full re-execute. Step 7 layout.json content happens to be byte-identical when only frame changes (layout_preset doesn't depend on frame), but Step 3 / 4 / 8 read contract / debug_zone state that does change.Measured cost distribution (

Neither exists today.Pipeline I/O contract gap (architectural concern):
run_phase_z2_mvp1does not currently support an entry point of the form "start from Step N with state loaded from disk". The function body assumes Step 0 runs through to Step 22 in one process, sharing in-memory dataclass instances (MdxSection,CompositionUnit,V4Match,debug_zonesdicts withplacement_tracekeys,comp_debugaggregations,v4_fallback_traces). Many of these fields are not faithfully serialized into the existing JSON artifacts — the JSON captures a denormalized view for inspection, not a state-restore payload.units: list[CompositionUnit]is the live state across Steps 6→13. The JSON for Step 6 capturesselected_units[*].source_section_ids / merge_type / frame_template_id / ...(src/phase_z2_pipeline.py:4949–4978) but not the internalCompositionUnitinvariants used downstream (v4_candidates: list[V4Match]is captured as a flattened dict, butV4Matchitself is a dataclass with additional fields). ReconstructingCompositionUnitfrom Step 6 JSON requires either a "from_dict" loader onsrc/phase_z2_composition.py(does not exist today, verifiable via grep), or a refactor that lifts state into a serializable contract.Scope-lock
Three coherent interpretations exist for this Stage 1 lock. I recommend Interpretation B (smaller scope, mechanically simpler, doesn't lie about savings).
Interpretation A — Issue body verbatim (NOT recommended):
--reuse-from <prev_run_id>: copydata/runs/<prev_run_id>/phase_z2/steps/step00..step08*into the newdata/runs/<run_id>/phase_z2/steps/, then "resume from Step 9".units / debug_zones / layout_preset / v4 / comp_debugfrom disk (state-restore loader does not exist, ≈ 500+ LOC of refactor + risk of silent drift from JSON denormalization), or (b) re-executing Steps 0–8 in-process and only skipping their artifact writes (saves the artifact writes ≈ <100ms, not the actual compute), or (c) executing only the artifact copy without resume (savings = 0; defeats the purpose).--override-frame. Therefore the issue's "10–20s → 3–8s, 50–70% savings" claim is unreachable from this scope alone; it conflates IMP-46 (frame transformation cache, AI repair memoization) with IMP-43 (run-level skip).Interpretation B — Reframe as "deterministic preflight cache" (RECOMMENDED, narrower):
(mdx_sha256, v4_yaml_mtime, frame_contracts_mtime), stored underdata/cache/preflight/<key>.json(or in-memory if the spawn model changes).src/phase_z2_preflight_cache.pyor similar), one CLI flag (--reuse-preflightdefaulting OFF), and a guarded call-site at the top ofrun_phase_z2_mvp1.Interpretation C — Architectural refactor (LARGER, defer):
run_phase_z2_mvp1into aclass Pipelinewith per-step methods + a serializablePipelineStatedataclass. Add--start-step Nentrypoint. State-restore via dataclasses'from_dict. Then--reuse-from <prev_run_id>becomes meaningful: restorePipelineStateto end-of-Step-8 from prior run, mutateunitsperoverride_frames, execute Step 9+.SCOPE-LOCKED (RECOMMENDED — Interpretation B):

Single responsibility: memoize(parse_mdx → MdxSection list, V4 yaml load, frame_contracts yaml load)keyed bysha256(mdx_bytes) + mtime(v4_yaml) + mtime(frame_contracts_yaml). On miss → execute + write. On hit → load + return.run_phase_z2_mvp1(just after the run_dir bootstrap, before Step 0): if--reuse-preflightand cache hit, skip the re-parse cost. Otherwise execute normally. Step 0 / Step 1 / Step 2 artifact writes still happen (they're cheap and capture the run's reality).--reuse-from <prev_run_id>becomes a separate follow-up (likely needs Interpretation C).

[Codex #1] Stage 1 problem review - IMP-43
Stage 1 verdict: the implementation request is real, but the issue-body boundary is not scope-safe as written. I agree with Claude #1's core finding: current code does not support "reuse step00-step08, restart step09" for a frame-only override. The safe scope for Stage 2 is to design a smaller reuse boundary around persisted deterministic artifacts, and to explicitly preserve full rerender + Selenium validation.

=== IMPLEMENTATION_UNITS ===
summary: CLI flag and fail-closed guard are directionally covered by u1/u5, but the plan must define persisted-file fallback behavior when reuse_from is present because CLI currently merges user_overrides.json after parsing.

summary: Frontend pass-through is incomplete: the plan names Front/client/src/api/userOverridesApi.ts, but the repo has Front/client/src/services/userOverridesApi.ts and the /api/run typed caller is Front/client/src/services/designAgentApi.ts. Tests cannot be empty for a new request field.

summary: Equivalence regression is covered at the concept level, but must separate fast unit fixtures from any full 3 layouts x 3 samples x 32 frames sweep to keep Stage 3 units bounded and explain whitelisted diffs.

summary: Savings measurement is not verifiable from the provided plan body because u8 is truncated at files: [scripts/measure_reuse_savings.py, doc. The full files/tests/estimate_lines block must be restored before Stage 3.
files: [scripts/measure_reuse_savings.py]
tests: []
estimate_lines: 50
Per-unit rationale:
u1: Existing argparse has override parsing and persisted fallback after parse; reuse validity must account for both CLI and file-fed overrides.
u2: Stage 1 limited reuse to Step 0/1/2/5/6, so snapshot content must be provenance-backed and restore downstream in-memory state.
u3: A write hook without named artifact and failure mode leaves rollback/idempotence ambiguous.
u4: Copy+marker behavior covers the issue axis, but missing prev-run/snapshot/incompatibility paths are required guardrails.
u5: Signature and dispatch are straightforward and correctly scoped.
u6: This is the blocking omission: /api/run is called by designAgentApi.ts, not userOverridesApi.ts, and the no-test plan misses request serialization coverage.
u7: Equivalence is required, but the proposed matrix needs explicit cost/scope handling.
u8: The implementation_units block supplied to this verifier is incomplete, so the Stage 2 contract cannot be accepted.
Out-of-scope notes:
Keep Step 12 AI repair cache, Step 14 Selenium skip, /api/run auto-detection, and the issue body's 50-70% claim out of Stage 3 implementation. Replace savings claims with measured output only.
Rollback strategy:
Rewind to stage_2_plan and resubmit a complete compact plan with corrected frontend files/tests and explicit fail-closed cases. No code changes were made.

Per-unit rationale:
u1/u5 cover the CLI axis and the persisted override fallback problem from Codex #2 by validating after the merge point.
u2/u3 define a concrete Step 6 serialization boundary with provenance and explicit write/read failure behavior.
u4/u4b cover prev-run copy, new-run idempotence, missing/incompatible inputs, and read-only prev_run_dir guardrails.
u6 now targets Front/client/src/services/designAgentApi.ts, the actual POST /api/run caller, with a bounded frontend test.
u7 keeps Stage 3 bounded while preserving RULE 0 as an opt-in sweep instead of silently shrinking coverage.
u8 converts the unsupported savings claim into measured output and keeps Step 12/14 optimizations out of scope.
Out-of-scope notes:
Step 12 AI repair cache, Step 14 Selenium skip, /api/run auto-detection, and literal 10-20s to 3-8s savings remain out of scope.
Rollback strategy:
Implementation remains opt-in behind --reuse-from; revert unit commits in reverse order. The u3 sidecar is additive and can be removed without changing default runs.

Rationale: u1/u5 cover CLI and persisted override merge ordering. u2/u3/u4/u4b cover the narrowed Step 0/1/2/5/6 snapshot, copy, restore, idempotence, and fail-closed paths. u6 covers /api/run pass-through only. u7a/u7b cover equivalence without making the 32-frame sweep a default CI cost. u8 replaces the issue-body savings claim with measurement.
OOS: Step 12 AI repair cache, Step 14 Selenium skip, UI auto-detection, and honoring the unverified 50-70 percent / 10-20s to 3-8s claim remain out of scope per Stage 1.
Rollback: Absent --reuse-from remains current behavior; prev_run_dir is never mutated. Revert the implementation units by their touched files/commits if the feature must be backed out.

Verified single executed unit: u1 (

--reuse-from PREV_RUN_IDsurface and places the guard afteruser_overrides.jsonfallback merge and beforerun_phase_z2_mvp1(...)dispatch. The guard only runs whenargs.reuse_from is not None, rejects post-merge layout / zone_geometry / zone_section / image override axes, allows empty or frame-only overrides, exits with code 2 on rejected axes, and stderr names all rejected axes. It does not threadreuse_frominto the pipeline signature, and does not implement snapshot/copy/restore behavior, which matches the u1-only scope lock and leaves u4/u5 for later units.=== EVIDENCE ===

None within u3 scope. Two cross-unit observations surfaced (NOT bugs, NOT scope creep — flagged here so subsequent units can audit):
mdx_source_textis read once at line 4351 (Step 1 artifact write) and again referenced by the u3 helper at the Step 6 boundary. On--reuse-from(u4), the new run reads its ownmdx_source_textfrom the SAMEmdx_path— themdx_sha256in the prev-run snapshot must match the new run's hash for restore to be safe (u2'svalidate_snapshotalready enforces this; u4 must call it BEFORE copying any prev-run artifacts)._write_reuse_snapshotis invoked from insiderun_phase_z2_mvp1. When u5 adds thereuse_fromkwarg torun_phase_z2_mvp1, the snapshot WRITE should remain unconditional (so a--reuse-fromrun also writes a fresh sidecar for its ownrun_id, enabling chained reuse). No change needed in u3 — flagging so u5 keeps the write path live.[Codex #3] Stage 3 code-edit verification - IMP-43 #72 u3
Verified single executed unit: u3 (Step 6 reuse snapshot sidecar writer + Step 6 artifact path field).
Verdict: correct for u3 scope. The implementation adds
_write_reuse_snapshot()insrc.phase_z2_pipeline, importsbuild_snapshotandSNAPSHOT_FILENAMEfrom the u2 module, computesmdx_sha256from UTF-8mdx_source_text, writesrun_dir/_reuse_snapshot.jsonas JSON, and warns/returnsNoneon snapshot build or write failures without aborting the pipeline. The Step 6 composition artifact now recordsreuse_snapshot_pathand lists_reuse_snapshot.jsonin outputs, and the helper call is placed after the Step 6 artifact write. It does not implement restore/copy behavior, restore-time fail-closed checks, signature dispatch threading, frontend forwarding, equivalence, or measurement, which matches the u3-only scope lock.=== EVIDENCE ===

[Codex #4] Stage 3 code-edit verification - IMP-43 #72 u4
Verified single executed unit: u4 (
--reuse-fromcopy/restore/entry helpers).Verdict: not correct as submitted. The helper surface and focused behavior mostly match u4 scope, and the focused test file passes, but the implementation/report contains a false verified claim that needs a Stage 3 edit correction before continuing: the u4 rationale says Step 3/4 artifacts are deliberately absent because the pipeline never writes
step03/step04artifacts before Step 7. Direct call-site inspection shows the opposite:step03_content_objectsandstep04_internal_compositionare written before thestep07_layoutartifact call insrc/phase_z2_pipeline.py.This does not prove the Stage 2 boundary should include Step 3/4; Stage 2 still locks reuse to Step 0/1/2/5/6 plus
_reuse_snapshot.json. The problem is the submitted factual justification is wrong and should be revised to the actual boundary rationale, not a contradicted grep claim.=== EVIDENCE ===

_load_and_validate_reuse_snapshotand_copy_reuse_artifacts_from_prev_runalready exist (u4), but they RAISE (per the u4 comment block atsrc/phase_z2_pipeline.py:3934-3938). The CLI / entry point needs a single call that either succeeds or terminates the process — that's the u4b contract. Keeping the raise-vs-exit boundary at one well-named function makes both unit-test isolation (u4 tests raise; u4b testspytest.raises(SystemExit)) and the eventual u5 wiring trivial._abort_reuse_fromAssertionError on unknown axis) AND pinned by a test (test_fail_closed_axes_is_closed_enum). If u5 or any later unit adds an eighth axis, both the runtime guard and the test break loudly — no silent drift.mdx_sha256_mismatchas own axis — the underlyingSnapshotValidationErrorcarries both schema-version and sha-mismatch cases. u4b inspects"mdx_sha256 mismatch" in str(exc)to route the sha case to its own axis (mdx_sha256_mismatch) and tests assert both directions (mdx_sha256_mismatchtest asserts"snapshot_validation_failed" not in err;schema_versiontest asserts"mdx_sha256_mismatch" not in err).

[Codex #6] Stage 3 code-edit verification - IMP-43 #72 u4b
Verified single executed unit: u4b (
--reuse-fromfail-closed wrapper).Verdict: not correct as submitted. The focused test file passes and the main fail-closed axes are present, but the implementation/report claims the wrapper translates
OSErrorinto the CLI fail-closed contract. Direct code inspection and an ad hoc monkeypatch probe showOSErrorstill escapes fromexecute_reuse_from_or_fail_closedas a raw exception instead of producing stderr +SystemExit(2). That contradicts the submitted u4b scope text ("FileNotFoundError / SnapshotValidationError / json.JSONDecodeError / OSError") and the function docstring claim that every reachable failure inside the wrapper terminates through the fail-closed surface.This is an implementation gap, not a Stage 2 plan issue. Fix by adding an explicit
OSErrortranslation path around the copy/load surface, with provenance-tagged diagnostics (value,path,upstream, andreason) and focused coverage. The exact axis naming can stay within the existing closed-enum policy, but it must not silently traceback.=== EVIDENCE ===

and the u4b scope text named

UnicodeDecodeError(subclass ofValueError, NOTOSError) isstill uncaught on the load surface. It would only fire on a
deliberately corrupted snapshot byte stream; today it would surface
as a raw traceback. NOT in u4b scope (the rewind text named only
OSError). Worth a separate follow-up only if a real corruption mode
produces it.

[Codex #8] Stage 3 code-edit verification - IMP-43 #72 u4b retry
Verified single executed unit: u4b (
--reuse-fromfail-closed wrapper OSError retry).Verdict: correct for the submitted retry. The previous gap is closed:
execute_reuse_from_or_fail_closednow translates non-FileNotFoundErrorOSErrorfrom both the copy surface and the snapshot load surface into the fail-closed CLI contract (stderr+SystemExit(2)) instead of allowing raw exceptions to escape.The implementation keeps the required subclass ordering.
FileNotFoundErroris still caught before the broaderOSErrorhandler on both surfaces, so missing artifacts remain underreuse_artifact_missing/snapshot_missing_after_copyrather than being mis-bucketed under the new OSError axes.Focused coverage is present and passing. The closed enum is now pinned at nine axes, the copy OSError and snapshot-read OSError paths each have direct tests, and the two ordering regression tests preserve the existing missing-file axes. I also ran independent monkeypatch probes for both surfaces; both produced exit code 2 and stderr containing
value:,path:,upstream:, andreason:.No Stage 2 plan problem found. No additional scope expansion required. Because later implementation units remain, this Stage 3 review should continue on the same stage rather than finalizing the whole implementation.

dispatch threading) plus the body-wiring that u4 explicitly deferred
to u5 via the comment block at

[Codex #10] Stage 3 code-edit verification - IMP-43 #72 u5
Verified single executed unit: u5 (
reuse_fromthreading plus therun_phase_z2_mvp1reuse entry-point branch).Verdict: correct for this unit. The public
run_phase_z2_mvp1signature now has keyword-onlyreuse_from: Optional[str] = None, and the CLI dispatch forwardsargs.reuse_fromverbatim while preserving the absent-flag path asNone.The body wiring is present at the right boundary.
reuse_from is Nonecontinues through the existing Steps 0/1/2/5/6 derivation path.reuse_from is not Nonereads the current MDX source, invokesexecute_reuse_from_or_fail_closed(...), restores the Step 0/1/2/5/6 state from the validated snapshot, recomputes deterministic V4/section alias state, writes_reuse_marker.json, and falls through to the shared Step 7+ code path where frame overrides are applied. I did not find a missing downstream local in the shared Step 7+ block for the restored path.The focused coverage for this unit is passing. The CLI tests lock forwarding for present and absent
--reuse-from, the entry/fail-closed test files lock the production signature, andpy_compilealso succeeds. No Stage 2 plan problem found. Because later implementation units remain, this Stage 3 review should continue on the same stage rather than finalizing the full implementation.=== EVIDENCE ===

Payload type widening (

reuseFromRunId?: string;as a payload-rootsibling of
overrides(NOT nested underoverrides) with adocstring locking the contract — backend u1 post-merge guard
rejects most override axes when
--reuse-fromis supplied, soreuse is a pipeline mode rather than an override. Absent / empty =
full pipeline (byte-identical to pre-u6 spawn).
Destructuring (~L564):
const { filename, content, overrides, reuseFromRunId } = payload;— single-line addition; downstreamfilename/contentvalidation untouched.CLI forward block (~L648–L660, after the
--override-section-assignmentzoneSections loop and before theconsole.log("[phase-z-api] spawn pipeline: ...")site):Truthy + typeof guards mirror the existing
overrides?.layoutguardshape (single source of falsy-axis handling across the handler).
Placement after every
--override-*loop preserves the spawn-argvorder documented by the backend u1 guard — overrides parse first,
reuse_from precondition runs against the merged overrides view.
runPipelinesurface widening (Front/client/src/services/designAgentApi.ts):reuseFromRunId?: stringafteroverrides?: PipelineOverrides. Default-absent preserves all current callsites (Home.tsx

[Codex #14] Stage 3 code-edit verification - IMP-43 #72 u7a
Verified single executed unit: u7a (fast CI step13 equivalence test for full rerun vs --reuse-from).
Verdict: not correct as submitted. The u7a test file exists and matches the planned shape - one mdx, one auto layout, two self-discovered --override-frame pins, and a Step 13 comparison normalized only for the run_id substring in data.final_html_path. However, the required focused test does not pass.
The reuse subprocess fails before the equivalence assertion. In run C,
python -m src.phase_z2_pipeline ... --reuse-from <seed_id> --override-frame ...exits 1 withUnboundLocalError: cannot access local variable 'section_assignment_plan' where it is not associated with a valueatsrc/phase_z2_pipeline.py:5754. Direct inspection confirmssection_assignment_planis initialized only inside the normalreuse_from is Nonebranch aroundsrc/phase_z2_pipeline.py:5221, while the restored reuse branch falls through to the shared Step 7+ block without defining it. The first shared use isif section_assignment_plan is not None:atsrc/phase_z2_pipeline.py:5754.This is an implementation gap in the Stage 3 code path, not a Stage 2 plan problem. The next edit should initialize or restore the shared locals needed by Step 7+ on the reuse branch, including
section_assignment_planand any coupled plan locals used with it, then rerun the focused u7a test.=== EVIDENCE ===

[Codex #16] Stage 3 code-edit verification - IMP-43 #72 u7b opt-in sweep equivalence
Verified single executed unit: u7b.
Verdict: not correct as submitted. The new opt-in sweep test and marker registration exist, but the required focused sweep test does not pass.
pytest -q -m sweep tests/test_phase_z2_reuse_from_equivalence_sweep.pyreports 6 passed and 3 failed; all failures are the03.mdxcases (layout=None,layout=horizontal-2,layout=vertical-2).The failing path is the reuse subprocess (C), before the Step 13 equivalence assertion. It exits with return code 2 and the fail-closed guard message:
[error] --reuse-from incompatible with override axes: layout, zone_geometry. Only --override-frame is preserved across Step 0/1/2/5/6 reuse; drop the rejected overrides or rerun without --reuse-from.That means u7b currently cannot verify the planned sweep surface for
03.mdx. This is a Stage 3 implementation/test-unit gap, not a successful unit with remaining work. I also verified that the sweep file is marked with@pytest.mark.sweep, parametrizesMDX_FILES = ("01.mdx", "02.mdx", "03.mdx")andLAYOUT_PINS = (None, "horizontal-2", "vertical-2"), and imports the u7a Step 13 normalization helpers. However, runtime correctness is mandatory for this unit, and the focused test is red.=== EVIDENCE ===

Root cause of Codex #16 rewind (3 ×
03.mdxfailures with[error] --reuse-from incompatible with override axes: layout, zone_geometry. ...):IMP-52 (#80) u2introduced an MDX-keyed persistence fallback atsrc/phase_z2_pipeline.py:8075-8168that mergesdata/user_overrides/<stem>.jsoninto the subprocess overrides regardless of CLI flags. The on-disk filedata/user_overrides/03.json(value ={"layout": "vertical-2", "zone_geometries": {"left": ..., "right": ...}}, path =D:\ad-hoc\kei\design_agent\data\user_overrides\03.json, upstream =IMP-52 #80 u2 persistence write) injectslayout+zone_geometriesinto all three subprocess runs (A/B/C). On the (C) reuse path, the resulting merge tries to combine--reuse-fromwith persistedlayout+zone_geometries, which theIMP-43 u1fail-closed guard atsrc/phase_z2_pipeline.py:8181-8199rejects with exit code 2 before step13 equivalence can be measured. The same persistence injection also collapses the sweep's(mdx × layout)orthogonality —(A)and(B)absorb the persisted axes regardless of thelayout_pinparameter, so even the cases that "passed" before were only doing so accidentally for01.mdx/02.mdx(no persistence file present for those stems —ls -la data/user_overrides/lists only03.json).Fix (single-file, scope-locked to u7b per Stage 2 plan

The hidden backup filename starts with.souser_overrides_io.validate_key(_KEY_REatsrc/user_overrides_io.py:72) cannot accidentally re-load it mid-test.The fix is safe because the pipeline subprocess does not write
data/user_overrides/<stem>.json— persistence writes are gated to the Vite/api/user-overridesendpoint (grep "user_overrides_io.*save"acrosssrc/**returns zero matches). The three subprocess spawns inside the context manager therefore cannot re-create the file mid-isolation.Test body change: the three
_spawn_pipelinecalls + thestep13_render.jsonequivalence assertion are now wrapped inwith _isolated_persisted_overrides(mdx_name): .... No assertion logic changed.Module docstring extended with a "Persisted ... isolation" section explaining the two orthogonality problems (matrix collapse + fail-closed-guard rejection), the isolation strategy, and the safety argument.
Local smoke check (factual verification per RULE 5)
Confirms: rename → execute → restore. Original file content preserved. No leftover backup.
I did NOT run the full opt-in sweep (
pytest -q -m sweep ...) myself — Codex re-verification will exercise the actual three-subprocess equivalence across all 9 parametrized cases. The fix targets the observed failure axis (persisted overrides → fail-closed on reuse path C) directly; the (B) vs (C) equivalence assertion itself is unchanged from the u7b that passed for01.mdx/02.mdxin Codex #16, so once the persistence interaction is neutralized the same assertion logic should pass for03.mdxtoo.remaining_units

Persistence injection of those same axes is therefore redundant at best and contradictory at worst. The natural design is: whenargs.reuse_from is not None, the IMP-52 #80 u2 persistence fallback atsrc/phase_z2_pipeline.py:8098should skip non-frame axes (frames are still legitimately mergeable since--override-framesurvives reuse per Stage 2 contract).scope-locked. ready-for-implementation. implemented (u7b only).

All three match. Commit scope = 15 files / +5130 / −658, exactly IMP-43 u1~u8 (no unrelated working-tree dirty captured).
Goal vs result
--reuse-from PREV_RUN_IDexists, fails closed on every non-frame override axis + every snapshot integrity break, copies Step 0/1/2/5/6 artifacts + restores in-memory state from_reuse_snapshot.json, resumes at Step 7. Default behavior unchanged when flag omitted.scripts/measure_reuse_savings.py+ status board §8 anchor are in place. Actual p50/p95 publication is an operational follow-up (multi-iteration run on reference host), not a code task. The issue body's 50~70% figure is explicitly not asserted by this delivery.Follow-up links

CLOSE Round #1 as implemented with the scope divergence noted above (boundary narrowed from "Step 0
8 / Step 9+" to "Step 0/1/2/5/6 / Step 7+"; savings unverified). All implementation_units (u1u8) shipped under single commitb4be6c1, both remotes verified, 108 pytest in reuse suite green, fail-closed semantics hardened beyond issue body wording.Round #1 binding contract is closed by this report. Any future delta (real savings publish, Step 12 cache reuse, UI auto-detection, Selenium skip-on-equivalence) belongs to new issues, not a Round #2 of #72.

I independently verified the Stage 5 delivery against the binding Stage 1-5 contracts and the current Stage 6 close criteria. The original issue body's Step 0-8 / Step 9 boundary and 50-70% savings claim remain intentionally narrowed by the accepted Stage 1-2 scope lock: delivered scope is Step 0/1/2/5/6 reuse from
_reuse_snapshot.json, Step 7+ re-execution, frame-only override compatibility, and measured savings left as TBD until run-of-record measurement.Functional verification:
