The caller sends a `repository_dispatch` event to the protected - central control plane every hour; it does not copy the repair engine into the - product repository. - - ## Cadence and bounded work - - The heartbeat runs at minute 11 of every hour. It asks the central scheduler - to inspect up to 100 open `main` pull requests, dispatch at most one repair, - and enforce a one-hour same-head retry floor. Non-cancelling concurrency - avoids terminating a legitimate long-running run merely because the next - heartbeat arrived. - - The central scheduler performs root-cause analysis and remediation feasibility - screening. Queued checks, reviewer latency, missing independent approval, - provider delay, billing limits, and unavailable credentials are operational - states rather than evidence of a source defect. They must not produce invented - commits. - - ## Credential, model, and authority boundaries - - The caller uses only the established `PR_REVIEW_MERGE_TOKEN`, falling back to - `OPENCODE_APPROVE_TOKEN`, to create the central dispatch event. Its generated - `GITHUB_TOKEN` remains read-only. The caller receives neither - `NVIDIA_NIM_API_KEY` nor any model prompt or source archive. The central, - separately reviewed OpenCode worker owns NVIDIA NIM access and repair - execution. `COPILOT_GITHUB_TOKEN` is not a model, scheduler, review, or merge - credential in this path. - - A repair cannot approve itself, weaken checks, label pending evidence as - passing, replay an ambiguous state-changing tool call, or bypass independent - non-author approval. Exact-head CI, security review, coverage, docstrings, and - branch protection remain authoritative. - - ## Standalone and ecosystem behavior - - The product remains independently deployable. The dispatch payload contains - only repository identity, protected base, queue bounds, and retry cadence. - Central `.github` may improve the repair engine without importing product code; - Contextual Orchestrator continues to own provider routing, tool execution, - credential authority, audit behavior, and release evidence. - - ## Verification and rollback - - Permanent tests bind the cron, single-flight policy, one-dispatch limit, - one-hour retry floor, exact target, read-only caller permission, explicit - credentials, and absence of model or Copilot secrets. Rollback removes the - caller, test, and this record; it does not change reviewer identities, central - worker secrets, branch protection, or product runtime behavior. - - ## APA 7th references - - GitHub, Inc.
