It uses OpenCode + with NVIDIA NIM and does not approve or merge pull requests. + +Merge eligibility remains owned by the separate merge scheduler, branch +protection, required checks, independent review, and unresolved-thread policy. +The repair worker proposes changes only; it cannot reinterpret queued or failed +checks as success. + +## Clearfolio execution contract + +The default Clearfolio caller provides the following immutable operating +parameters to the reusable scheduler: + +```yaml +target_repository: ContextualWisdomLab/clearfolio +base_branch: main +max_prs: "50" +max_dispatches: "1" +retry_hours: "1" +``` + +The scheduled heartbeat is `23 * * * *`. Repository-scoped concurrency and +`cancel-in-progress: true` ensure that a superseded Clearfolio queue scan does +not overlap its successor. At most one repair dispatch is created per run. + +The caller passes only the established `PR_REVIEW_MERGE_TOKEN` and +`OPENCODE_APPROVE_TOKEN` scheduler credentials. It does not receive or forward +`NVIDIA_NIM_API_KEY`; the model credential is scoped exclusively to the two +OpenCode execution steps in the separately reviewed autofix worker. + +## Reusable target-selection contract + +The shared scheduler resolves its target in this order: + +1. `repository_dispatch` payload `target_repository`; +2. reusable-workflow input `target_repository`; +3. repository variable `PR_REVIEW_FIX_TARGET_REPOSITORY`; and +4. the repository in which the scheduler executes. + +This ordering keeps standalone operation possible while preventing the central +module from silently hard-coding one product. Clearfolio's product-specific +choice is visible in its dedicated caller. A sibling service can add its own +small caller or invoke the reusable workflow directly without copying the +scheduler implementation, OpenCode configuration, or model credentials. + +`canonical_ref` remains an accepted deprecated input only so callers pinned to +older workflow interfaces can upgrade without a coordinated breaking change. +It is never read and cannot choose executable scheduler code. + +## Immutable reusable-workflow source + +GitHub associates the ordinary `github` context in a reusable workflow with the +caller. 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. The +worker snapshots the complete pre-model repository through the trusted central +helper, including ignored paths, tracked files, other untracked files, file modes, +regular-file hashes, and symbolic-link targets. It then verifies the complete +post-model inventory after temporary OpenCode configuration is restored and +before any stage, commit, or push. + +The authoritative allowlist is NUL-delimited. Ordinary repair receives only +current-head file-scoped actionable review paths. Conflict repair receives only +Git's exact unresolved paths from `git diff --name-only -z --diff-filter=U`. +An empty ordinary allowlist authorizes no changes. + +The verifier rejects created, deleted, modified, mode-changed, retargeted, +ignored, dangling, directory-backed, external-link, metadata-race, and other +out-of-scope paths. 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. + +## RCA and remediation-feasibility gate + +Every failed check, unresolved actionable review, merge conflict, or scheduler +error is first treated as evidence to diagnose, not as a reason to guess at a +patch. Before editing, the worker establishes the root cause from the exact +current PR head and base, then lists the smallest plausible remediation +candidates. + +A candidate is feasible only when all of the following are true: + +- the current worker has repository-writer authority for the target repository; +- every required edit is inside the sealed allowed paths; +- credential and protected-setting requirements can be satisfied without + weakening branch protection, tests, review independence, or secret isolation; +- stack and dependency order permit the change on the current branch; +- a focused test or exact-head check can verify the result; and +- the action actually changes the root cause rather than only restating the + blocker, rerunning unchanged evidence, or manufacturing a passing status. + +The worker implements only the smallest candidate that passes this gate. When no +repository edit is feasible within the worker's authority, it leaves the tree +unchanged and records the concrete failed feasibility condition. The parent queue scan must then continue with the next eligible bounded PR or buyer-visible product gap instead of ending the productive portion of the hourly run. + +Queued reviews or checks remain merge blockers, but their latency does not make +an unrelated code edit realistic. The scheduler may inspect another independent +PR, strengthen non-conflicting tests or documentation, or select one bounded +product slice; it must not claim an external approval, runner capacity, billing +change, or protected-setting mutation that it cannot actually perform. + +## 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. This does not replace syntax, allowlist, merge-marker, exact-head, or +branch-protection checks. + +Before publication, the worker re-reads the live PR head. 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. A successful push creates a new head +that must be reviewed and checked again; the worker does not synthesize approval. + +## Security and MSA boundary + +The scheduler may inspect review state and dispatch the already-reviewed bounded +autofix workflow. It cannot approve its own changes, lower branch protection, +convert queued checks to success, publish releases, or bypass independent +review.

The product-neutral +engine remains `.github/workflows/pr-review-fix-scheduler.yml` and contains no +scheduled trigger or Clearfolio repository literal. + +This split is an architecture decision rather than a naming preference. A +scheduled workflow executes in the repository that contains it. Letting a +central reusable workflow fall through to `github.repository` would scan +`ContextualWisdomLab/.github`, not Clearfolio, unless a mutable external variable +happened to be configured correctly. Conversely, hard-coding Clearfolio inside +the shared engine would make the reusable module misleading for naruon, +contextual-orchestrator, and other CWL services. + +## Product caller + +The Clearfolio caller runs at minute 23 of every hour and invokes the local +reusable workflow with explicit, reviewable values: + +```yaml +target_repository: ContextualWisdomLab/clearfolio +base_branch: main +max_prs: "50" +max_dispatches: "1" +retry_hours: "1" +``` + +The caller and reusable engine both use `cancel-in-progress: true`. This keeps +queue inspection single-flight at the product and engine boundaries. At most one +autofix dispatch is issued during an invocation, and the same exact PR head is +not retried more than once per hour. + +## Modular MSA contract + +The shared workflow accepts explicit `target_repository` and `base_branch` +inputs. A sibling product may add a small schedule caller with its own exact +repository and base branch, or invoke the engine through an approved dispatch. +It does not copy the scheduler implementation, OpenCode configuration, repair +worker, or credential logic. + +The shared target-selection precedence remains: + +1. validated `repository_dispatch` target; +2. reusable-workflow caller input; +3. `PR_REVIEW_FIX_TARGET_REPOSITORY` repository variable; +4. the workflow execution repository. + +The product-specific caller resolves the target before this fallback chain is +needed. Clearfolio therefore has a functioning default heartbeat without +changing the engine's standalone or modular semantics. + +## Credential and privilege boundary + +The caller passes exactly two established optional scheduler credentials: + +- `PR_REVIEW_MERGE_TOKEN`; +- `OPENCODE_APPROVE_TOKEN`. + +It does not use `secrets: inherit`. It does not receive +`NVIDIA_NIM_API_KEY`, because queue inspection and dispatch are not model +execution. The NVIDIA credential is bound only inside the separately reviewed +`PR Review Autofix` workflow's two OpenCode execution steps. + +Both the caller and reusable scheduler keep the workflow-generated +`GITHUB_TOKEN` read-only with only `contents: read`; neither declares job-level +write elevation. Cross-repository PR inspection, acknowledgement, workflow +dispatch, and branch updates are authorized only through the explicitly mapped +`PR_REVIEW_MERGE_TOKEN` or `OPENCODE_APPROVE_TOKEN`, exposed to the scheduler as +`GH_TOKEN`. The scheduler has no `github.token` fallback. Missing credentials +therefore fail closed instead of silently broadening the workflow token. + +The repair worker still cannot approve a PR, merge a PR, publish a release, +lower branch protection, or convert incomplete checks into success. + +## Failure behavior + +A missing cross-repository scheduler credential causes the target inspection or +dispatch to fail rather than silently changing the target to the central +repository. A missing NVIDIA credential later causes the autofix worker to fail +before model execution. Neither failure weakens independent review, security +checks, branch protection, or manual maintenance paths. + +Scheduled workflows are active only from the protected default branch.

That violates the existing separation +between untrusted repository state and trusted workflow state. + +MITRE CWE-22 describes path-validation failures in which pathname handling lets +a resource resolve outside its intended restricted location. The direction here +is inverted—the security requirement is that trusted control evidence resolve +**outside** the untrusted worktree—but the same canonical-path principle applies: +security decisions must be made against the path's effective resolved location, +not only its textual spelling. GitHub likewise requires privileged Actions +workflows to treat pull-request-controlled content as untrusted and recommends +strong separation when privileged workflows process such content. + +The invariant is intentionally simple and auditable: + +1. canonicalize and validate the repository root; +2. obtain the control file's absolute path; +3. resolve existing symbolic-link components without requiring a not-yet-created + snapshot output to exist; +4. reject if either representation is the repository root or one of its + descendants; and +5. only then read or write the control file. + +No repository path is added to an allowlist to work around this rule.

Review and repair have different privileges: +the review path publishes a verdict, while the autofix path may modify and push +a same-repository pull-request branch. Sharing or silently replacing the review +credential would couple two independent controls and weaken incident +containment. + +## Central MSA ownership + +`ContextualWisdomLab/.github` owns the scheduler, dispatch authorization, +model-provider configuration, credential binding, immutable worker source, and +fail-closed repair contract. Leaf repositories receive the behavior through the +central reusable workflow and do not copy provider credentials or scheduler +implementation. + +The central scheduler runs once per hour, dispatches at most one repair per +invocation, and binds its implementation to the immutable called-workflow +source. Clearfolio owns only its small product caller. Naruon, +contextual-orchestrator, Inkspan, and other CWL services may adopt separate +callers while retaining standalone operation and the same central security +boundary. + +## Immutable repository-dispatch worker source + +`PR Review Autofix` is a default-branch-only `repository_dispatch` workflow. +GitHub defines `GITHUB_SHA` for `repository_dispatch` as the last commit on the +default branch and runs only a workflow file present on that branch. The +workflow therefore checks out its co-located context builder and policy source +at the exact workflow-run commit: + +```yaml +repository: ContextualWisdomLab/.github +ref: ${{ github.sha }} +fetch-depth: 1 +persist-credentials: false +``` + +Without the explicit `ref`, `actions/checkout` would resolve the repository's +moving default branch at checkout time. A later default-branch push could then +replace trusted scripts after GitHub had already selected the workflow run, +creating a time-of-check/time-of-use gap around a job that receives OIDC and +branch-write capability. The exact SHA keeps helper source aligned with the +workflow revision selected for dispatch. + +The client payload remains untrusted metadata. It identifies a target only after +the worker re-reads live pull-request state and verifies the exact repository, +open state, same-repository branch, base ref and SHA, and head ref and SHA. + +## Provider contract + +The pinned OpenCode runtime enables only `nvidia-nim` through the +OpenAI-compatible adapter and NVIDIA hosted endpoint: + +```text +https://integrate.api.nvidia.com/v1 +``` + +The primary repair model is `mistralai/mistral-small-4-119b-2603`. The +`ci-autofix` agent and its model configuration both request high reasoning +through OpenCode's provider-option contract (`reasoningEffort: "high"`). NVIDIA's +Mistral Small 4 NIM API documents the corresponding request behavior as +`reasoning_effort: "high"`, which enables the model's reasoning mode. The small +model used for bounded helper work remains `nvidia/nemotron-3-nano-30b-a3b` and +is not a fallback provider. GitHub Models configuration, identifiers, base URLs, +and model-auth fallbacks are absent from the scheduled autofix execution path. + +The high-reasoning setting is deliberate for write-capable review repair. This +workflow optimizes correctness, evidence quality, and controllability rather than +latency. It does not imply that deeper reasoning is universally superior; the +setting is an explicit operational choice for this bounded, security-sensitive +writer role and remains subject to exact-head regression evidence. + +## Credential boundary + +The organization secret is bound as: + +```yaml +NVIDIA_API_KEY: ${{ secrets.NVIDIA_NIM_API_KEY }} +``` + +It is present only on the two steps that execute OpenCode: ordinary +review-feedback repair and merge-conflict repair. 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 model execution step does not bind a GitHub write token. Its later +commit-and-push step may mutate only with `PR_REVIEW_MERGE_TOKEN`, +`OPENCODE_APPROVE_TOKEN`, or the short-lived OpenCode GitHub App token exchanged +from OIDC. The conflict-repair shell uses the same three mutation authorities +because the reviewed shell must re-read the live head and publish a verified +merge after model execution. Both mutation-capable paths evaluate an explicit +credential-availability guard before any Git write and fail closed when none of +those authorities exists. The workflow-generated `github.token` remains +read-only and is never accepted in a mutation credential expression. + +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. +Review-thread text is untrusted authorization input, so paths beneath `.github/` +or `scripts/ci/` are categorically excluded from the ordinary review-derived +allowlist. A reviewer therefore cannot turn an inline comment on a workflow, +CODEOWNERS file, action, scheduler, or CI helper into permission for the +autonomous writer to modify its own control plane. Such changes require a +separately scoped, independently reviewed control-plane change rather than the +review-autofix path. + +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 after rejecting control-plane paths beneath +`.github/` and `scripts/ci/`; the workflow converts the remaining paths 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. + +A later Strix security review found that the review-derived allowlist still +accepted control-plane paths. The finding was reproduced test-first at +`4ab7693ae2fe5ed93c59ca84f93a757bed1477bd` with a regression covering workflows, +actions, CODEOWNERS, and CI helpers. Production head +`a8b7663580bba108a6d2186658b5acae478d2fc8` then rejected `.github/` and +`scripts/ci/` paths while retaining ordinary product-source repair. Its focused +quality run executed 1,075 tests plus 16 subtests and measured 100% statement and +branch coverage for both autofix production helpers, with 100% public docstrings. +That exact-head evidence is historical after any later documentation commit and +must be re-established on the new current head. + +The later writer-model and mutation-authority hardening was likewise captured by +permanent RED contracts before the implementation changed. Those contracts pin +the exact NVIDIA Mistral Small 4 writer, high reasoning, absence of the obsolete +Mistral Nemotron identifier, explicit mutation credentials, and guards that run +before any Git write. 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, uses the exact Mistral Small 4 writer with + high reasoning, 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. mutation-capable ordinary and conflict paths accept only established explicit + secrets or the exchanged OpenCode app token, never `github.token`, and fail + closed before Git writes when no mutation authority exists; +5. trusted helper source is checked out at the immutable workflow-run SHA; +6. ordinary review-thread authorization rejects `.github/` and `scripts/ci/` + control-plane paths before producing the sealed allowlist; +7. ordinary and conflict repair both snapshot before model execution and verify + after temporary configuration restoration but before staging; +8. tracked, untracked, and ignored-path inventories, symlink targets, mode + changes, deletions, creations, and metadata races are covered; +9. both OpenCode permission maps deny `.git` and `.git/*` after the catch-all + edit rule; +10. every privileged commit and push disables repository hooks through + `core.hooksPath=/dev/null`; +11. every push uses the explicit target URL and never model-mutable `origin`; +12. the independent review workflow retains its exact reviewed Git blob SHA; +13. the production helper retains 100% statement and branch coverage and 100% + public docstrings; and +14. 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, review-derived control-plane path exclusion, `.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 +review-thread authority over `.github/` or `scripts/ci/`, 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*.
