The per-space single-writer lock — Redis CAS leader lock (SET NX PX, DEL-CAS and PEXPIRE-CAS Lua), the in-process mutex, the per-process instanceId and the heartbeat — lived inline in GitSyncOrchestrator. Extract it into a dedicated @Injectable() SpaceLockService exposing one narrow surface, withSpaceLock(spaceId, fn), so the lock is the orchestrator's only Redis-lock touch-point and is testable in isolation. The orchestrator now injects SpaceLockService and both consumers (runOnce, ingestExternalPush) go through spaceLock.withSpaceLock — behavior unchanged (same sentinel returns, same 503-on-lock-held contract). Orchestrator drops 591→472 lines. Adds space-lock.service.spec.ts asserting the lock SEMANTICS against a fake Redis (the test-coverage warning from the review): the SET NX/PX args, the DEL-CAS and PEXPIRE-CAS Lua + ARGV[1]=instanceId, plus the lock-held / in-progress / throw- still-releases paths. The orchestrator spec is unchanged in count and stays green (it now builds the real SpaceLockService over its mock Redis). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
