## Summary - make `thread_source` an explicit optional thread-level field on `thread/start`, `thread/fork`, and returned thread payloads - persist `thread_source` in rollout/session metadata so resumed live threads retain the original value - replace the old best-effort `session_source` -> `thread_source` mapping with an explicit caller-supplied analytics classification ## Why Before this change, analytics `thread_source` was populated by a best-effort mapping from `session_source`. `session_source` describes the runtime/client surface, not the actual thread-level origin, so that projection was not accurate enough to distinguish cases such as `user`, `subagent`, `memory_consolidation`, and future thread origins reliably. Making `thread_source` explicit keeps one thread-level analytics field while letting callers provide the real classification directly instead of recovering it indirectly from `session_source`. ## Impact For new analytics events, `thread_source` now reflects the explicit thread-level classification supplied by the caller rather than an inferred value derived from `session_source`. Existing protocol fields remain optional; callers that omit `threadSource` now produce `null` instead of a best-effort inferred value. ## Validation - `just write-app-server-schema` - `cargo test -p codex-analytics -p codex-core -p codex-app-server-protocol --no-run` - `cargo test -p codex-app-server-protocol generated_ts_optional_nullable_fields_only_in_params` - `cargo test -p codex-analytics thread_initialized_event_serializes_expected_shape` - `cargo test -p codex-core resume_stopped_thread_from_rollout_preserves_thread_source`
