Context

Patchwarden needs analytics after merge and across agent loops: did the PR actually improve the system, did it trigger follow-up failures, did the agent feedback loop converge, and which cheese-slices were predictive. comet-ml/opik looks relevant as an open-source observability/evaluation platform for LLM apps and agentic workflows.

Goal

Decide whether Opik should become the first analytics sink for Patchwarden, or remain a future optional exporter behind the Patchwarden-native analytics schema.

Desired shape

Start from Patchwarden-owned events/artifacts, e.g. patchwarden.post_merge_feedback.v1, patchwarden.agent_loop.v1, and reviewer verdict summaries.
Evaluate whether Opik can ingest these without leaking private diffs, secrets, raw prompts, or excessive repo context.
Prefer optional exporter/module over making core depend on Opik.
Capture cost/ops burden: self-hosting, storage, retention, and local/private deployment assumptions.

Open questions

Is Opik lightweight enough for GPT/Codex-loop analytics now, or should Patchwarden first define its own small JSONL/event contract?
Which events are valuable enough to export: PR verdicts, reviewer failures, post-merge health, agent repair cycles, or all of them?

Acceptance

Short decision note: adopt now / optional exporter later / reject.
If adopted: minimal exporter contract and sanitized example event.
Status/docs updated to show analytics gap and selected direction.

🏛️ Architect (operator-directed park)

Parked — Opik is a later optional exporter, not a near-term core concern. This is Loop 2 (post-merge analytics), and the correct sequence is:

First land the native event contract (#147 post_merge_feedback.v1 + agent-loop events). Patchwarden owns its own small JSONL/event shape.
Then optionally export to Opik behind (a) a sanitization boundary (no private diffs, secrets, raw prompts, or excessive repo context) and (b) an explicit egress posture in the D23 discipline (nothing leaves to a non-local sink unless posture is allowed).

Core must never import Opik. Revisit only after #147 lands and N=1 dogfood actually produces events worth exporting. — claude (architect)

✅ Resolved by #157 (merged) — docs/operations/opik-analytics-sink-decision.md records the decision: optional exporter later, never a core dependency; native post_merge_feedback.v1 first; sanitization + self-host-default + D23-style egress posture; exporter failure is advisory not a merge blocker; analytics never mutates trust without a separate verdict + controller recheck. Faithful to the #152 park guidance. Closing. — claude (architect)
