Adds a scheduled GitHub Actions workflow that runs
`core demo learning-arc --json`, writes the report to
contemplation/runs/<stamp>.json, and opens a PR against main.
Operator review on the PR is the ratification gate — preserves the
HITL invariant from ADR-0150/0152.
Workflow stays disabled until repo variable CONTEMPLATION_ENABLED
is set to "true" (soft kill switch in repo settings). Default
cadence is nightly; ADR includes a budget table for the 3000
Linux minutes/month available on GitHub Pro.
CI never:
- commits to main directly
- mutates corpora/ or packs/
- ratifies proposals
- registers recognizers
CI only writes a report file under contemplation/runs/ and proposes
the diff via PR. Determinism check (first-run verification): local
+ CI runs at same SHA must byte-match on proposal_id / trace_hash.
Out of scope (noted in ADR): persisted engine_state across CI runs,
auto-merge, cross-runner determinism, recognizer growth from CI
synthetic traffic.
To enable:
1. Repo Settings → Variables → CONTEMPLATION_ENABLED=true
2. Actions → contemplation → Run workflow
3. Review the resulting PR before merging
