Verify — TFW-60 / Phase A review revision 4

Mindset: Verify. Reproduce the quality-bearing claims and classify the evidence. File and line quantities are deliberately not evaluated.

Independent verification

ID	Quality claim	Independent check	Result
V1	The evidence names a stable implementation snapshot	Resolved afd24f5 and compared it with the later RF/EV report commit	✅ The pin exists and the report correctly describes a prior immutable snapshot
V2	The implementation remains internally coherent	Ran the complete docs/scripts pytest suite	✅ 220 passed, 1 skipped
V3	The build gate validates task-local truth	Ran python docs/scripts/gen_index.py --validate	✅ Validation passed for the repository
V4	The derived index is reproducible but non-authoritative	Ran python docs/scripts/gen_index.py --check before the reviewer transition and inspected the locality tests	✅ Index was current; tests preserve the rule that index staleness cannot block a task transition
V5	Reviewer changes introduce no whitespace defect	Ran git diff --check before the trace write and again after it	✅ Clean
V6	Shipped adapters carry the canonical rules	Compared command/workflow and Codex-skill copies byte-for-byte with their sources	✅ No adapter drift
V7	Current participant accountability is enforced in real entry points	Inspected and ran tests through collect and main --validate for absent/empty team/, agent accountability, and a declared human	✅ The production path fails closed for the TS-named cases and accepts the valid case
V8	Actor, accountability, and provider remain separate concepts	Inspected profile parsing and event validation plus direct regression tests	✅ Actor must be declared; accountability must be human; via remains provider metadata
V9	Legacy history remains readable without weakening the published current grammar	Inspected legacy classification, current templates, canonical-surface regression tests, and repository validation	✅ Immutable old events remain readable and current instructions are actor-bearing
V10	Identifier semantics are consistent	Inspected canonical instructions/templates and their shipped-copy regression guard	✅ {ID} consistently denotes the complete identifier; superseded doubled-slug examples are gone
V11	Migration and task locality serve the approved purpose	Rechecked migration refusal/accounting tests, status authority, journal append model, and the non-blocking index gate	✅ No normal task transition requires a shared aggregate edit; the legacy corpus remains represented
V12	Current worktree safety is preserved	Inspected status and commit history without staging or modifying unrelated work	✅ Existing TECH_DEBT and TFW-54/55 changes remain untouched

AC-14 verification

Item	Verification	Result
Participant validation fails closed and reads profiles	Production tests cover missing/empty declarations; direct and production tests distinguish a human from an agent	✅
Legacy escape is scoped	Classification is carried by the durable legacy filename grammar; the current canonical route always writes an actor-bearing name	✅ within the supported, non-adversarial operating model
Production path is exercised	Both index collection and command-line validation are covered	✅
Canonical naming sweep is complete	Shipped instructions/templates and adapter copies agree on whole-ID and actor-bearing forms	✅
Regression guard targets shipped surfaces	The test reads the actual canonical files rather than only fixtures	✅
RF/EV are rebuilt from one pin	RF, EV, and measurement log name afd24f5	✅
Evidence is measured against a named commit	The pin resolves and is intentionally earlier than the report commit	✅

Evidence classification

All quality-bearing RF/EV claims needed for the verdict are supported by source inspection, the pinned snapshot, or rerun commands. The evidence package no longer relies on mutable HEAD for its final claim. Rows whose sole subject is file quantity, line quantity, diff volume, or budget arithmetic are excluded by owner direction and have no weight in this review.

The RF's explicit non-claims remain correctly bounded: this phase does not claim cross-device transport behavior, a second-machine concurrency result, or comprehension by a non-specialist. Those remain assigned elsewhere and do not reduce Phase A quality.

Prior findings

The first review's purpose failure remains closed. Revision 2's corrections remain present. Revision 3's identity, naming, production-path, and evidence-pin items are closed under the review boundary above. No regression was found in their ordinary supported scenarios.
