feat: add CI causal memory observation v0.1 - #234
Conversation
📝 WalkthroughWalkthroughThe change adds schemas for CI causal observations and memory graphs, Python CLIs for deterministic observation emission and memory aggregation, regression tests, and workflow steps that verify the commit and retain observation artifacts. ChangesCI causal memory
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds immutable CI observations and advisory cross-run aggregation without merge, deployment, or repository-write authority. It is mergeable with owner awareness: the reusable aggregation path still needs follow-up to verify failure signatures, reject malformed observations cleanly, and publish related files atomically, while the schema should align with the emitter’s success/failure rules.

Addressed both unresolved findings on exact head
The published files were re-read at the new head. No local replay is claimed while the workspace executor is unavailable; exact-head GitHub CI and CodeRabbit re-review are pending. Causal memory remains advisory-only. |

validate_observationrejects a success observation that carries afailure_signature, and rejects a non-success observation without one (lotus_family_ci_observation.pylines 278-284). The schema does not express either rule. A consumer that validates an artifact with a JSON Schema validator alone accepts both inconsistent shapes.Add a conditional so the schema and the Python validator state the same contract.
