altered fields with a valid-format key now fail before durable-leader election or forwarding, and wrapper write permission is job-scoped. - Bound both trusted-uv quality jobs to `github.event.pull_request.head.sha` and added a permanent two-checkout regression contract so exact-head compatibility, coverage, docstring, and compilation claims cannot silently measure GitHub's generated pull-request merge revision. - Made Strix treat only a single LiteLLM provider-error line containing NVIDIA NIM context and model-catalog 404 evidence as cross-model fallback evidence, rejecting cross-line signal assembly and provider-like target source literals; moved the public default to Nemotron 3 Super 120B and added a second NVIDIA hosted candidate before GitHub Models without neutralizing reported vulnerabilities. +- Bind reusable scheduler implementation to the validated called-workflow repository, SHA, ref, and file path, and verify the checked-out commit before executing privileged scheduler logic. +- Removed the ambiguous central-repository schedule fallback that could scan `.github` instead of Clearfolio when no external variable was configured;

Consequently, a privileged called workflow must not use caller-derived +`github.sha`, a caller payload, or a mutable branch such as `main` to select its +co-located implementation. + +The checkout step instead uses: + +```yaml +repository: ${{ job.workflow_repository }} +ref: ${{ job.workflow_sha }} +``` + +`job.workflow_repository` identifies the repository that contains the called +workflow and `job.workflow_sha` identifies its immutable resolved commit. The +workflow validates repository, SHA, workflow ref, and file path before checkout, +then verifies the resulting Git revision before executing the scheduler helper. +Checkout credentials are not persisted. + +The later repository-dispatch worker similarly checks out trusted central helper +source at `${{ github.sha }}`. The dispatch payload does not select executable +worker code. + +## Exact model write scope + +Ordinary and conflict repair use the same fail-closed worktree comparison.

It invokes a fixed validated `/usr/bin/git`, bounds path and +inventory sizes, and emits redacted static failures for filesystem races. A +symlink target must be a regular in-repository path present in the reviewable Git +inventory. + +Both OpenCode permission objects allow ordinary file repair but explicitly deny +`.git` and `.git/*`. Model child processes also receive neither GitHub write +credentials nor Actions OIDC request credentials. These permission controls are +defense in depth; the complete pre/post snapshot remains authoritative. + +## Privileged Git publication + +Every reviewed commit and push runs with `core.hooksPath=/dev/null`, preventing a +repository hook from executing after model work with the privileged GitHub +credential.

It reconstructs an +explicit revalidated repository URL from `GITHUB_SERVER_URL` and the exact target +repository and supplies that URL directly to `git push`. It never trusts +model-mutable `origin`, `remote.origin.url`, push URLs, aliases, or hooks as the +publication destination. + +A head movement, unresolved marker, missing merge state, out-of-scope write, +malformed repository identity, absent model credential, or failed validation +terminates the run without publication.

Metadata collection, +checkout, context preparation, validation, commit, and push do not receive the +NVIDIA credential. A missing key is a fatal configuration error rather than a +signal to choose another provider. + +The ordinary repair step does not bind a GitHub write token at step scope. The +conflict-repair shell retains GitHub credentials because the same reviewed shell +must re-read the live head and publish a verified merge after model execution. +Both model child processes run through: + +```text +env -u GITHUB_TOKEN -u GH_TOKEN \ + -u ACTIONS_ID_TOKEN_REQUEST_TOKEN -u ACTIONS_ID_TOKEN_REQUEST_URL +``` + +The child receives the NVIDIA model credential and non-secret execution +controls, but cannot call GitHub APIs or mint an Actions OIDC token. GitHub +credentials remain available only to reviewed shell logic before or after the +child process. The key is never written to repository files, generated prompts, +command arguments, or ordinary logs. + +## OpenCode repair sandbox + +OpenCode permission rules use pattern matching and the last matching rule wins. +Both the global permission map and the named `ci-autofix` agent therefore allow +ordinary repository file edits first and then explicitly deny `.git` and +`.git/*`. The simple wildcard contract means the catch-all may match nested +paths, so the later Git-specific rules are required rather than descriptive +comments. + +The worker also denies every non-file interaction unnecessary for bounded repair: + +- `bash`; +- `task`; +- `skill`; +- `question`; +- `webfetch`; +- `websearch`; +- `lsp`; +- `external_directory`; and +- `doom_loop`. + +The agent may read, search, list, and edit the validated same-repository PR +worktree. It receives an authoritative file allowlist derived from current +file-scoped actionable review context. An empty allowlist authorizes no change. +The shell independently syntax-checks changed Python, validates changed workflow +files when `actionlint` is present, rechecks the live head, and refuses unresolved +merge markers. + +## Exact ordinary and conflict repair write boundary + +The ordinary and conflict repair modes use the same fail-closed model-write +boundary. This closes a prior asymmetry in which conflict repair had a complete +snapshot while ordinary repair depended only on a later visible Git diff. + +Before either model process starts, the worker creates: + +1. a NUL-delimited authoritative allowlist of exact paths; and +2. a deterministic snapshot of the complete pre-model worktree, including ignored paths, + tracked paths, non-ignored untracked paths, file modes, regular-file SHA-256 + values, sizes, and symbolic-link targets. + +For conflict repair, Git supplies the allowlist through `git diff --name-only -z +--diff-filter=U`. For ordinary repair, the context builder supplies current-head +file-scoped actionable paths, which the workflow converts to a sorted +NUL-delimited file. In both cases, temporary OpenCode configuration is installed +only after the snapshot and restored before verification. + +The trusted helper calls a fixed validated `/usr/bin/git`. Git's official +`git-ls-files` contract is used twice: cached plus non-ignored other paths form +the reviewable inventory, while `--others --ignored --exclude-standard` adds the +ignored-path inventory. Combining both results prevents model-created cache, +credential, build-output, or other ignored paths from escaping comparison merely +because a later `git add -A` would normally omit them. + +The helper refuses noncanonical roots and paths, oversized inventories, malformed +snapshot documents, unrecognized fingerprint schemas, and allowlist paths absent +from the pre-model snapshot. Every symlink must resolve to a regular file inside +the repository whose target is present in the reviewable Git inventory. +External, ignored-target, dangling, directory-backed, and metadata-race links +fail closed with bounded diagnostics that do not expose private filesystem +exceptions. + +After OpenCode exits, the workflow restores any prior repository configuration +and compares the current inventory with the snapshot. Created, deleted, +modified, mode-changed, retargeted, ignored, dangling, directory-backed, +external-link, metadata-race, or other out-of-scope writes reject the run before +staging. Verification is not replaced by the ordinary later diff check; both +remain independent defenses. + +## Git metadata, hooks, and push destination + +Model-editable repository state must not control the privileged publication +step. Both OpenCode permission objects deny `.git` and `.git/*`, but the reviewed +shell also treats permission enforcement as defense in depth rather than proof. +The full snapshot detects out-of-scope worktree changes, and every privileged +commit and push invokes Git with `core.hooksPath=/dev/null`. + +Git documents that hooks can execute at commit and push lifecycle points and that +`core.hooksPath` selects their directory. Disabling hooks for these two commands +prevents a repository-provided or model-created hook from executing with the +post-model GitHub credential. The worker still performs explicit syntax, +allowlist, marker, and live-head checks; hook suppression does not weaken those +gates. + +Before push, the worker reconstructs an explicit revalidated repository URL from +`GITHUB_SERVER_URL` and the exact live `TARGET_REPOSITORY`. It supplies that URL +directly to `git push` instead of trusting model-mutable Git metadata such as +`remote.origin.url` or a push URL. The branch ref and exact head are validated +again immediately before publication. + +The repair worker cannot approve its own changes, lower branch protection, +reinterpret queued or failed checks, manufacture independent review, merge a PR, +or publish a release. Those decisions remain with separate protected workflows +and repository policy. + +## Independent review-agent boundary + +`.github/workflows/opencode-review-dispatch.yml` is not modified by this slice. +The regression contract pins that workflow's Git blob SHA byte-for-byte rather +than inferring independence from provider-name strings. The existing reviewer +retains its own separately reviewed identity, model pool, and credential chain. + +This is a control separation, not naming convention. Review produces a verdict +that may gate merge; autofix proposes branch changes. Their credentials, +workflow sources, and change histories remain independent. + +## Test-first evidence + +The ordinary write-scope defects were captured before production repair: + +- RED exact head `6db97138f93869d04bfac0aba935844323b20b50`; +- focused run `31149695625` failed exactly the three new contracts for ordinary + snapshot verification, Git-control-file and hook isolation, and explicit push + destination while the pre-existing tests remained green; +- production repair began at + `3e124301cc27e04f9f4d4daf079bc8cd32fa9757`; +- the ordering regression was corrected without weakening the conflict boundary + at `b68c85cec8c14e226bf31e299571541826d89f50`; and +- documentation RED head `3b0e3a9c8f17032b57263d162e52dfd3f239fa4b` + and run `31150267219` failed only the new public-record contract while 72 + focused tests and complete production statement and branch coverage remained + green. + +Predecessor-head successes are historical TDD evidence, not merge evidence. The +final integrated head must establish every required quality, security, review, +and protection gate again. + +## Verification contract + +Automated tests prove: + +1. the caller retains its approved one-hour cadence; +2. OpenCode enables only NVIDIA NIM and receives the model key only in its two + execution steps; +3. missing model credentials fail closed and model children receive no GitHub or + OIDC write credential; +4. trusted helper source is checked out at the immutable workflow-run SHA; +5. ordinary and conflict repair both snapshot before model execution and verify + after temporary configuration restoration but before staging; +6. tracked, untracked, and ignored-path inventories, symlink targets, mode + changes, deletions, creations, and metadata races are covered; +7. both OpenCode permission maps deny `.git` and `.git/*` after the catch-all + edit rule; +8. every privileged commit and push disables repository hooks through + `core.hooksPath=/dev/null`; +9. every push uses the explicit target URL and never model-mutable `origin`; +10. the independent review workflow retains its exact reviewed Git blob SHA; +11. the production helper retains 100% statement and branch coverage and 100% + public docstrings; and +12. exact-current-head security, automated review, independent approval, + unresolved-thread, and branch-protection gates pass before merge. + +## Scheduling and activation + +The NVIDIA worker does not create a second repair scheduler. It is consumed by +the hourly central review-fix scheduler and product caller. Scheduled workflows +run only from the protected default branch, so feature-branch checks do not make +the heartbeat active. Activation requires protected integration and accepted-main +verification. + +## Rollback + +Rollback must revert the NVIDIA transport, ordinary and conflict repair scope +contracts, `.git` denial, ignored-path inventory, hook suppression, explicit push +destination, tests, operator guidance, doctoring, and changelog as one reviewed +change. A partial rollback that restores ordinary diff-only validation, +model-mutable Git metadata, repository hooks, GitHub-token model authentication, +or a mutable helper checkout is unsafe. + +If NVIDIA NIM is unavailable, scheduled repair must fail closed while read-only +review, required checks, manual maintenance, and protected merge policy remain +available. Rollback is not permission to bypass independent approval or release +gates. + +## References + +Git Project. (2026). *git-ls-files*.
