+# Self-Healing CI Pipeline
+
+This repository implements a self-adapting repair pipeline to fix CI failures and project drift automatically.
+
+## Triggers
+
+1. **Scheduled:** Runs on a self-computed cadence based on repository activity to catch drift.
+2. **Reactive:** Triggers automatically whenever the main CI workflow fails on `main`.
+3. **Manual:** Can be triggered manually via `workflow_dispatch` in the Actions tab.
+
+## The Repair Pipeline (6 Steps)
+
+The pipeline is idempotent and uses existing tooling:
+
+1. **Rebuild/Reinstall:** Clean installation of dependencies (`npm ci`).
+2. **Auto-Format:** Runs `prettier` to fix formatting drift.
+3. **Update Snapshots:** Runs tests to update Vitest snapshots.
+4. **Update Type Stubs:** Synchronizes TypeScript definitions.
+5. **Update Lockfile:** Updates dependencies.
+6. **Build Project:** Runs the build command.
+
+After each step, a health check is performed. If the project becomes healthy and there is a diff, it safely generates a Pull Request for human review. It fails closed to prevent erroneous code pushes.
+
+## Schedule Computation
+
+The `compute_schedule.mjs` script runs weekly. It analyzes the recent `git log` to determine commit frequency and adjusts the cron schedule for the proactive self-heal runs automatically. A PR is opened if the schedule needs to be updated.
+
+## Manual Overrides
+
+If you wish to override the schedule manually:
+1. Edit `.github/self-heal-schedule.yml`.
+2. Commit the changes. The pipeline respects manual changes up to the next periodic recompute.
+
+## Reviewer Checklist for Self-Heal PRs
+- [ ] Review the drift summary.
+- [ ] Ensure no secret files or tokens were inadvertently modified.
+- [ ] Check if the changes match expected snapshot/formatting updates.
+- [ ] Approve and merge manually (auto-merge is disabled by design).
