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.

Review: approve

Approve.

The change narrowly fixes the hidden --spawn-config-json loss point by carrying the already-resolved spawner manifest.session.record_event_trace into SpawnPodTool and serializing [session].record_event_trace = true only when the parent has opted in. It also adds focused coverage for profile artifact preservation, spawned config preservation, disabled omission, and clarifies trace sidecar semantics as normalized provider/lifecycle diagnostics rather than byte-for-byte raw SSE.

Blocker findings: none.

Validation re-run by reviewer:

• cargo test -p manifest profile_artifact_preserves_session_record_event_trace — passed.
• cargo test -p pod spawn_config — passed, 4 tests.
• ./tickets.sh doctor — passed.
• git diff --check 23f234d^ 23f234d — passed earlier during inspection.
• Worktree status is clean.

Final verdict: approve.
