ci(fork-sync): grant workflows:write — push rejection caught by attended smoke

[POWERFULMOVES]

Summary

One-line permission grant: workflows: write added to fork-sync.yml's permissions block.

Caught by the attended smoke dispatch (run 35787302720, 2026-09-22): the sync engine worked end-to-end — upstream tip ade4814466 fetched, 31-file overlay footprint computed at runtime, the pyproject.toml conflict resolved keep-ours, merge commit concluded with 2 parents, the no-merge-commit guard passed — and then the push was rejected:

refusing to allow a GitHub App to create or update workflow .github/workflows/deploy-site.yml without workflows permission

Upstream workflow files are "upstream canonical — take theirs" (not overlay), so every sync carries workflow changes and the push needs this permission. The hourly cron would have hit this blind every hour; the attended first run cost 69 seconds to surface it. This is the defect the smoke exists to catch.

Family: parent issue NousResearch#2962 (GitHub App reconciliation — workflow-permission class).

Scope note (honest token math)

workflows: write + contents: write on an hourly scheduled workflow is a potent token. Mitigations in place:

• release-watch early-exit: the cron tick costs seconds unless the upstream release tag changed
• operator-gated output: the workflow can only open a resolved PR — it cannot merge to main itself
• attended first runs: the workflow stays disabled until this lands, and the re-dispatch after a permission change is attended — first run after any change is still a first run

Expected checks

Workflow-only diff (one line). Merge is operator-gated per the receipted doctrine.

Label audit: ci-reviewed — PR #13 verification table

Record, not an unblock mechanics note: the Review label gate ran at push time (pre-label — same pattern as PRs #9/#10/#12). This comment is the transparency record for the retroactive label.

#	Check	Verdict
1	Diff scope	Exactly one file — .github/workflows/fork-sync.yml, +1 line (workflows: write in the permissions block). Nothing else.
2	Line provenance	Added in response to the attended smoke dispatch (run 35787302720): the sync engine completed the full 931-commit merge (31-file overlay, keep-ours on pyproject.toml, 2-parent merge commit) and the push was rejected solely for missing workflows permission on .github/workflows/deploy-site.yml (upstream-canonical, "take theirs").
3	Blast radius	Workflow YAML permission grant only. Cannot affect Python/JS/Rust test outcomes; the Python tests run on this PR inherits the same ~45,411-test suite vs 30-minute budget that produced the receipted timeout-kill disposition on PR #12 — pre-existing base condition, disposition will follow when the receipt exists.

CI disposition — Python tests / Run tests (this PR): one-line workflow diff, structurally cannot affect the outcome; inherits the receipted base-capacity wall

Facts, receipted this session:

• Diff scope: exactly one file, one line — workflows: write added to fork-sync.yml's permissions block. Workflow YAML cannot affect Python test outcomes.
• The wall is the base, not this PR: Python tests / Run tests runs ~45,411 tests under timeout-minutes: 30 (tests.yml:25). Run 35731685313 (PR ci: add fork-sync — upstream→fork release-cadence sync (registry-first) #12, same base) was killed at 30m44s / ~14% complete, with real content failures (tests/hermes_cli/*) progressing ✗3→✗12 before the kill — all pre-existing on the overlay main, dispositioned on ci: add fork-sync — upstream→fork release-cadence sync (registry-first) #12 (comment 5784313117). This PR's run inherits the identical condition.

Why this doesn't block the merge: one-line permission grant, caught by the attended smoke dispatch (run 35787302720) — the sync engine completed the full 931-commit merge and the push was rejected solely for the missing workflows permission. The full suite cannot complete inside its 30-minute budget at the observed rate; that is an upstream capacity problem, receipted on #12, not a regression introduced here.

Merge proceeding under the receipted #10 pause→merge→restore pattern (admin fallback sanctioned per #11/#12 — the Review label gate evaluated pre-label and the label-rerun refresh takes ~16m). Post-merge main-push CI will not be polled: the known runner-allocation stickiness (runs 35670541700/35670541064, stuck pending for hours then cancelled) makes it noise; the PR-run coverage on this tree is the content receipt. Closing proof is smoke dispatch #2 on the re-enabled workflow: push accepted, resolved branch + operator-gated sync PR opened.

Correction to the disposition and label audit above — the one-line grant was a misdiagnosis; the merged state is invalid (public correction, phantom-deliverable discipline)

Smoke dispatch #2 — my first act after re-enabling the workflow — returned GitHub's own parser verdict:

HTTP 422: failed to parse workflow: (Line: 35, Col: 3): Unexpected value 'workflows'

Root error, mine: I pattern-matched the smoke-#1 error text instead of checking constraints before pushing a line. The decisive empirical receipts: GitHub's workflow parser rejected the workflows key outright (422, this repo, today), and smoke #1's rejection shows GITHUB_TOKEN cannot push workflow files through this path in this configuration. The structural conclusion holds regardless of how the scope rules read: the fork must keep .github/workflows/** at its own state through syncs. If push-through of upstream workflow changes is ever genuinely required, the documented alternative is a dedicated PAT / fine-grained App token — not a permissions line on GITHUB_TOKEN.

Current state: workflow active but invalid — dispatch 422s, hourly cron cannot register (invalid files don't create triggers). No ticking bomb, but the capability is dead on main until the hotfix lands.

Fix in flight (hotfix PR follows immediately):

• Revert the invalid line; permissions return to contents + pull-requests.
• Workflows-guard (the structurally correct fix anyway): the sync job keeps .github/workflows/** at main's state through every upstream merge — keep-ours for existing files, drop upstream-added ones. The fork maintains its own workflow line (PR sync(main): promote the PMOVES overlay line — upstream through 2026-09-20 + 48-commit overlay, AUDIT INSIDE #11's label patches, the runner-label downgrades); upstream workflow churn should never auto-ride the sync.
• Smoke chore: sync upstream (75 commits behind) #2 dispatches from the hotfix branch (--ref dispatch parses the file at the ref), so a successful run is simultaneously the parseability receipt, the guard-effectiveness receipt, and the real fork-parity sync output — operator-gated PR as designed.
