EV — TFW-50: Minimal Agent Commit Attribution¶

Date: 2026-08-05 Author: Codex / Executor Task: TFW-50 TS: TS TFW-50

Environment¶

Field	Value
OS	Microsoft Windows NT 10.0.26200.0
Shell	Windows PowerShell 5.1.26100.8655
Language / Runtime	Python 3.13.5; pytest 9.0.2
Git	2.42.0.windows.1
Deploy target	Local repository only; no deployment or publication authorized
CI / Pipeline	Local docs unit and MkDocs integration suites

Evidence¶

#	AC	What was verified	Environment	Result	Artifact
E1	AC-1	Sole normative owner, exact grammar, one section, one example, and no second owner	Repository source inspection	N/A	Verification Record V1
E2	AC-2	Exact term derivation plus Git author/committer, authentication, unmarked-human, body-schema, trailer, and numeric-limit boundaries	Repository source inspection	N/A	Verification Record V2
E3	AC-3	Universal Coordinator/Researcher/Executor/Reviewer applicability and absence of newly added commit cadence	Full active corpus and corrective diff	N/A	Verification Record V3
E4	AC-4	Four preserve-and-verify files remain byte-identical to their `389168a` blobs; push reconciliation remains explicit	Git blob comparison	N/A	Verification Record V4
E5	AC-5	Total implementation surface is exactly six existing paths; corrective execution changed only two; wider corpus has no subject/push conflict	Git diff and grouped corpus scan	N/A	Verification Record V5
E6	AC-6	Executor-observable history, regression tests, generated-path cleanup, and no-publication state passed; the current-task Reviewer commit and independent inspection remain pending `/tfw-review`	Local Git history and docs build	DEFERRED	Verification Record V6

Verification Record¶

V1 — Sole owner and grammar¶

Commit Attribution normative owner hits across the six implementation paths: 1, in .tfw/conventions.md.
Grammar: [agent/task/scope/role] summary.
Conventions contain one normative sentence and one example.
Glossary links to conventions §4 and does not repeat the grammar.

V2 — Exact terminology and boundaries¶

agent: lowercase AI product name from explicit context.
task: canonical TFW task ID; project only when none exists.
scope: established lowercase work-slice slug or lowercase hyphenation of its explicit label; no registry.
role: lowercase canonical workflow owner from conventions §15/Role Lock.
summary: short and imperative; no numeric limit, trailer, or body schema.
Glossary states that the prefix is first-line subject text, separate from Git author/committer metadata, not actor authentication, and not a classifier for unmarked commits.

V3 — Universal roles without cadence¶

Canonical Role Locks inspected: Coordinator (plan.md), Researcher (research/base.md), Executor (handoff.md), Reviewer (review.md).
The sole rule begins with “Every AI-authored commit”; no role-specific grammar was added.
Corrective added-text scan found 0 occurrences of per-stage, per-WAIT, per-STOP, per-workflow, per-artifact, per-file, or per-AC commit requirements.
Full active workflow/adapter/skill scan: 12 commit-family hits, 6 push-family hits, 0 automatic-push conflicts, 0 conflicting subject instructions, and 0 hybrid/maintainer subject roles.

V4 — Preserve-file byte stability¶

Path	`389168a` blob = final blob	Blob hash
`.tfw/workflows/handoff.md`	yes	`00baa9b2c9df93cc989d9b0841df22bfb8a06ea1`
`.agent/workflows/tfw-handoff.md`	yes	`44fea1c0da8665a5c948764f8d4e1a9bd5bea4c4`
`.claude/commands/tfw-handoff.md`	yes	`44fea1c0da8665a5c948764f8d4e1a9bd5bea4c4`
`RELEASE.md`	yes	`3ff41c298a5d4fbcc985f2c2850f8a766fce2aae`

The installed handoff Evidence drift is therefore unchanged in full, not merely visually equivalent.

V5 — Allowlist and protected state¶

Total implementation diff from bc6779e: exactly six existing paths, all in the TS allowlist; unexpected 0, missing 0.
Corrective diff c7a0055..420fdbe: only .tfw/conventions.md and .tfw/glossary.md.
New framework/runtime/config/state files: 0.
git diff --check: PASS.
Local and global core.hooksPath: unset; .git/hooks/prepare-commit-msg: absent.
No hooks, scripts, schemas, registries, manifests, config/state, validators, runtime enforcement, or history rewrite were introduced.

V6 — History, regression, cleanup, and publication boundary¶

Current range captured immediately before the EV/RF trace commit:

git log --format='%H%x09%s' bc6779e..HEAD: 14 subjects inspected; regex-invalid subjects: 0.
Coordinator representative: 021f039 — [codex/TFW-50/task/coordinator] approve all-role attribution revision.
Researcher representative: c768748 — [codex/TFW-50/iter1/researcher] synthesize commit-attribution research.
Executor representative: 420fdbe — [codex/TFW-50/task/executor] refine universal attribution terms.
Current-task Reviewer representative and independent range inspection: DEFERRED — pending /tfw-review.
Prior Reviewer compatibility example: 3935c53 — [codex/TFW-49/phase-c/reviewer] approve corrected repository-local enforcement.

The history demonstrates grammar expressibility and searchability only. Explicit delegation prompts required attribution during TFW-50, and the prior Reviewer examples were produced while rejected TFW-49 machinery existed; these are confounders. No causal compliance, authentication, or guaranteed actor-identification claim is made.

Regression and cleanup:

python -m pytest docs/scripts/test_gen_docs.py -q: 55 passed in 1.45s.
python -m pytest docs/scripts/test_integration.py -q: 13 passed in 91.22s.
Test-generated .pytest_cache/, docs/scripts/__pycache__/, and site/ were removed.
Pre-existing ignored user paths remained exactly: entities.json, mempalace.yaml, tasks/TFW-36__content_marketing_blog_series/.
origin/master remained bc6779e365b01118030ec577a47e6339f0fabf1c; pre-EV/RF local state was ahead 14, behind 0.
No push, fetch, tag, deploy, publish, or notify action was performed.

The EV/RF trace commit necessarily follows this snapshot; its attributed subject is reported in the Executor final handoff and must be included in the independent Reviewer range inspection.

Verdict¶

Evidence verdict: 0/6 VERIFIED, 1 DEFERRED, 0 BLOCKED, 5 N/A
