Summary

Classifies the LAST unclassified file. After this PR merges + the ledger-flip follow-up PR merges, unclassified_lines = 0 and the strict gate's classification condition is satisfied.

Level-1 Buddy Review APPROVED (Amara, 2026-04-29) with two named tightenings, both applied:

  1. Ledger tense — drop "will land" prose now that ops(0-0-0): ledger-flip after Batch 3a merge — 227→235 / 46→38 #841 has merged; in-force value is 235/0/38
  2. Soften item 5 (schedule-context input) from "would fail evaluation" to "less safe / less portable across contexts" since documentation-grounded but no local hard-failure proof

Six named regressions on AceHack-only +38 lines

  1. Auto-merge dead-end risk — AceHack arms gh pr merge --auto despite GitHub's anti-recursion guard (GITHUB_TOKEN-triggered events do not fire downstream workflow runs). LFG explicitly NOT armed with detailed limitation explanation citing Codex review Round 33 close hotfix — markdownlint green on main #25 P1.

  2. Token permissions (Scorecard TokenPermissionsID) — AceHack: broad top-level contents: write + pull-requests: write. LFG: top-level contents: read + job-level scoped per Scorecard. LFG commit 2ce1abb fix(scorecard): scope budget-cadence permissions job-level (TokenPermissionsID) (#679).

  3. Missing actions: read — AceHack drops it entirely; snapshot-burn.sh would 403 silently on Actions REST API calls and produce misleading zeroed timing data.

  4. AgencySignature validator inconsistency — AceHack: Human-Review-Evidence: signed-policy while Human-Review is not-implied-by-credential. Deployed validator requires Evidence="none" when not "explicit". LFG: Evidence="none".

  5. Schedule-context input expression — AceHack: ${{ inputs.note }} (less portable). LFG: ${{ github.event.inputs.note || '' }} (safer across schedule + workflow_dispatch).

  6. Persona-name attribution on current-state CI surface — AceHack: (per Amara ferry-7 + Grok ferry-16) + Per the four-ferry consensus. LFG: (per the canonical 10-trailer convention) (role-ref form, rule-compliant).

Ledger transition

Metric Pre-merge (in-force) Post-merge (atomic with this PR's merge)
potential_loss_lines 273 273 (unchanged)
classified_safe_lines 235 273 (+38 for budget-snapshot-cadence.yml)
unsafe_lines 0 0 (unchanged)
unclassified_lines 38 0

Arithmetic sanity check post-merge: 273 = 273 + 0 + 0 ✓.

Per the two-PR split (avoid contingent-prose churn): ledger headline NOT touched in this PR; lands atomically in a small follow-up PR after this merges.

After this PR + the ledger-flip-after-3b PR merges

The strict gate's classification conditions are satisfied:

unclassified_lines                       = 0  ✓
unsafe_lines                             = 0  ✓
binary_acehack_only_files                = 0  ✓ (verified earlier)
binary_modified_or_renamed_unclassified  = 0  ✓ (verified earlier)
binary_files_needing_forward_sync        = 0  ✓
binary_files_needing_human_decision      = 0  ✓

Remaining gate conditions are all operational + maintainer-irreversible:

  • fresh-clone fsck = clean
  • hard-reset preflight = clean
  • ls-remote-vs-fetch SHA match = verified
  • dry-run push shape = clean
  • maintainer signoff = yes ← Aaron's call

Test plan

  • All 6 named regressions cited with named LFG-side commits + named LFG content
  • Buddy review (Level-1) approved with tightenings applied
  • Tense discipline applied: in-force values used, no "will land" prose
  • Tightening 5 wording softened per buddy review
  • No ledger headline change in this PR (two-PR split discipline)
  • CI green
  • Codex / Copilot reviews resolved if any threads land

…t unclassified file, post-Level-1-buddy-review)

Classifies the LAST unclassified file. After this PR merges + ledger-flip follow-up PR merges, unclassified_lines = 0 and the strict gate's classification condition is satisfied.

Level-1 Buddy Review (Amara, 2026-04-29) APPROVED classification SAFE_TO_RESET_LFG_SUPERSEDES with two named tightenings, both applied:
1. Ledger tense — packet originally said "classified_safe_lines = 235 (#841 will land 235; this PR opened, not yet merged)". After #841 merged 2026-04-29T13:00:52Z, the in-force value is just 235. The packet now uses clean in-force values without "will land" prose (Evidence-Tense Discipline applied).
2. Item 5 (schedule-context input expression) — packet originally said AceHack's `${{ inputs.note }}` "would fail evaluation on schedule runs". Softened to "less safe / less portable across `schedule` + `workflow_dispatch` contexts" since I have documentation grounding (workflow_dispatch supplies `inputs`, schedule does not) but no local hard-failure proof.

Six named regressions on AceHack +38 lines (each cited with named LFG equivalent):

1. **Auto-merge dead-end risk**: AceHack arms `gh pr merge --auto` despite GitHub's anti-recursion guard (events triggered by GITHUB_TOKEN do not fire downstream workflow runs). Auto-merge would silently stall every weekly run. LFG explicitly NOT armed with detailed limitation explanation citing Codex review #25 P1.

2. **Token permissions** (Scorecard `TokenPermissionsID`): AceHack uses broad top-level `contents: write` + `pull-requests: write`. LFG uses top-level `contents: read` + job-level scoped `contents: write` + `pull-requests: write` + `actions: read` per Scorecard minimum-blast-radius best practice. LFG commit `2ce1abb fix(scorecard): scope budget-cadence permissions job-level (TokenPermissionsID) (#679)`.

3. **Missing `actions: read`**: AceHack drops `actions: read` entirely. snapshot-burn.sh's calls to Actions REST API would 403 silently and fall back to empty/zeroed timing data while still writing a snapshot — producing misleading evidence rather than a hard failure.

4. **AgencySignature validator inconsistency**: AceHack sets `Human-Review-Evidence: signed-policy` while Human-Review is `not-implied-by-credential`. The deployed validator (tools/hygiene/validate-agencysignature-pr-body.sh per task #298) requires Evidence="none" when Human-Review is not "explicit". AceHack-version PRs would be blocked. LFG sets Evidence="none" per the rule.

5. **Schedule-context input expression**: AceHack uses `${{ inputs.note }}` (less portable across schedule + workflow_dispatch contexts since `inputs` is supplied by workflow_dispatch but not schedule). LFG uses `${{ github.event.inputs.note || '' }}` which is safer across both.

6. **Persona-name attribution on current-state CI surface**: AceHack: `(Squash-Merge Invariant per Amara ferry-7 + Grok ferry-16)` + `Per the four-ferry consensus`. LFG: `(Squash-Merge Invariant per the canonical 10-trailer convention)` (role-ref form, rule-compliant per role-vs-name).

Ledger headline NOT touched in this PR (stays 235/0/38 as in-force pre-Batch-3b-merge). Per the two-PR split that avoided contingent-prose churn on prior batches: ledger flip 235→273 / 38→0 lands atomically with Batch 3b's merge in a small follow-up PR.

This PR also documents Aaron's 2026-04-29 question about `[skip ci]` — verified via WebSearch: GitHub Actions natively supports `[skip ci]` and variants in commit messages (since Feb 2021). Not the fix for the budget auto-merge issue (PAT is), but the feature is real. Captured in tick shard 1308Z.

…de span in table cell

CI gate.yml run on the batch-3b branch had to be manually dispatched (gate.yml didn't auto-trigger on PR open — separate operational issue worth investigating later). Run completed with two failures:

1. lint (markdownlint) — REAL FAILURE, my issue:
   - MD038/no-space-in-code: backtick code span `${{ github.event.inputs.note || '' }}` inside the Batch 3b table cell contained literal `||` which markdownlint parsed as table column separators, breaking column count (MD056: Expected 4, Actual 6).
   - Fix: escape the pipes as `\|\|` inside the code span.

2. build-and-test (windows-11-arm) + (windows-2025) — pre-existing infrastructure issue, NOT my issue:
   - global.json requires .NET SDK 10.0.203
   - Windows runners only have up to 10.0.202 (windows-11-arm) and 10.0.201 (windows-2025)
   - These are NOT in the required-status-checks list per branch protection (only macos-26, ubuntu-24.04, ubuntu-24.04-arm are required for build-and-test)
   - Won't block merge

Captured for deferred queue: gate.yml didn't auto-trigger on `pull_request: opened` event for this docs-only PR — manual `gh workflow run gate.yml --ref <branch>` recovered it. Worth investigating whether this is transient (Actions delivery delay) or a concurrency-group issue with rapid PR-create+arm-merge sequence. Same family as task #306.
…odex #25 xref

Two Copilot P1 findings on the Batch 3b evidence cell (lines anchored to pre-fix positions but issues persist):

1. **Role-vs-name rule** — Batch 3b evidence text contained persona-name attribution citing "Amara", "Grok", "Codex" inline. CLASSIFICATION.md is a current-state doc surface (not on the closed history-surface list). Fix: same minimum-invasive rewrite pattern as #838 round-3 — describe the wrong-form-attribution at meta-level instead of verbatim:
   - "Codex review #25 P1" → "an external AI reviewer's P1 finding on the AceHack-side originating PR (b42e9e5 ... #25)"
   - "(Squash-Merge Invariant per Amara ferry-7 + Grok ferry-16)" → "two persona-name attribution comments on this CI workflow file (one citing two named external-AI reviewers + their respective ferry-numbers as Squash-Merge Invariant authority...)"
   - "Per the four-ferry consensus" → "another prefixed 'Per the [N]-ferry consensus' framing"

2. **Xref clarity** — "Codex review #25 P1" was ambiguous: could be misread as PR #25 (which is unrelated). Now explicit: it's a review on the AceHack-side originating PR for this workflow (`b42e9e5 ... (#25)`).

Pre-existing persona names elsewhere in CLASSIFICATION.md (lines 30, 49, 61, 86, 149) are not new additions in this PR and would require a separate scope decision (same as #838 round-3 — not extending Aaron's "active-trajectory.md should count as history" call to CLASSIFICATION.md without an explicit maintainer call).

Local markdownlint also re-ran clean on the new content.

… strict gate's classification condition SATISFIED (#843)

Mechanical post-merge ledger update for #842 (Batch 3b, merged 2026-04-29T13:27:07Z, commit 84ea2c9). Per the two-PR split discipline that avoided contingent-prose churn.

This is the FINAL classification ledger update. After this PR lands:

```
potential_loss_lines  = 273
classified_safe_lines = 273  (ALL AceHack-only +lines have classified-safe semantic evidence)
unsafe_lines          = 0
unclassified_lines    = 0
Arithmetic: 273 = 273 + 0 + 0 ✓
```

The strict gate's classification conditions are SATISFIED:
- unclassified_lines                       = 0  ✓
- unsafe_lines                             = 0  ✓
- binary_acehack_only_files                = 0  ✓ (verified earlier)
- binary_modified_or_renamed_unclassified  = 0  ✓ (verified earlier)
- binary_files_needing_forward_sync        = 0  ✓
- binary_files_needing_human_decision      = 0  ✓

Remaining gate conditions are all operational + maintainer-irreversible:
- fresh-clone fsck                         = clean   (re-verify before destructive op)
- hard-reset preflight                     = clean   (re-verify before destructive op)
- ls-remote-vs-fetch SHA match             = verified (re-run before destructive op)
- dry-run push shape                       = clean   (re-run before destructive op)
- maintainer signoff                       = yes     ← Aaron's call

Pre-commit consistency sweep ran (Derived-Rollup Drift control): all metric mentions in active-trajectory.md + CLASSIFICATION.md verified consistent at 273/0/0.

Composition updates:
- active-trajectory.md classified_safe_lines composition: adds Batch 3b entry (38 lines, budget-snapshot-cadence.yml with six named regressions)
- active-trajectory.md unclassified_lines composition: now empty (strict gate's classification condition satisfied)
- CLASSIFICATION.md Batch 3b result paragraph: flipped from "lands in a small follow-up PR" to "flipped in this PR" + adds "All files now classified — strict gate's classification condition satisfied"

After this PR merges, the trajectory is ready for maintainer-irreversible hard-reset signoff (final destructive operation per the reversible-vs-irreversible authority rule).
