# Paired real server runtime transcript

Synthetic server fixtures only; no provider CLI, UI, live userdata, or dev server. Before is the exact ingestor source from 3cc31ed27c8956b36cee35a50509fb7c6869592b; after is 83ef5cf0b67c915b0db262e8089c84c6eb71a669. Other production source is identical between these commits. TestClock controls domain fixture dates (1970); trace and lock-holder timestamps are actual UTC wall time.

P=plain write; R=writeIfRunCurrent; O=writeIfProviderThreadOwner (late provider_thread.updated); S=secondary thread.model-selection-updated after primary subagent.updated. C=controls.

Representative P recover1 uses production PRAGMA busy_timeout=5000 on the real server connection. Supporting cases deliberately set that connection to 75ms. Separate Python sqlite3 process on the same canonical file holds BEGIN IMMEDIATE. Release is IPC-triggered only after an observed real LockTimeoutError (two for recover2); persistent releases after ingestion exhausts. No timers/sleeps/polling.

All outcomes below passed assertions for success/failure, target-event count, unique log IDs, projection state, and exact bounded attempts for the retry/error modes. `injected*` cases are explicitly synthetic classification tests; never real-lock evidence. `recheck` commits a concurrent model update through the real sink while holding the thread lock before the second model-selection read. Its event is excluded from the target secondary-write count.

A real EventSink stream subscribes before ingestion. Ready and completion domain-event markers use Deferred milestones; marker IDs are excluded from target/log counts. For the initial ingestion, every published event ID/type between markers equals the persisted log in order, with no duplicate IDs. The completion marker drains prior publications without sleeps or polling. Repeat-call assertions separately check the durable log and unchanged child selection.
