+## Plan
+
+Use the worktree + sibling coder/reviewer flow for this ticket.
+
+Intent packet summary:
+- Preserve `session.record_event_trace` through profile resolution and spawned-Pod manifest construction when the parent/profile enables it.
+- Keep event trace opt-in; do not globally enable it by default.
+- Treat `.trace.jsonl` as normalized provider stream/lifecycle diagnostics, not byte-for-byte raw SSE.
+
+Implementation direction:
+- Trace where `record_event_trace` is carried in profile-resolved manifests and where `SpawnPod` constructs hidden child spawn config.
+- Fix the narrow point where the setting is dropped/defaulted.
+- Add focused tests for profile/spawn config preserving `record_event_trace = true`.
+- Add a small documentation/comment clarification for trace sidecar semantics.
+
+Validation target:
+- Focused manifest/pod tests covering the changed path.
+- `./tickets.sh doctor` and `git diff --check`.
+
