Handles Synapse lane_paused responses by waiting and resuming indexing instead of failing or re-embedding finished work. Searches fall back to keyword search with the approved paused notice.
Releases build slots and locks while waiting; resumes from validated checkpoints and drops work for changed or deleted files.
Excludes pauses from failure breakers, reports paused with paused_until_ms, and rejects unknown pause fingerprints.
Adds fake-Synapse and fake-clock regressions; lazy checkpoints reduce median peak RSS by 17.6% on a 4,000-chunk corpus.
Confidence Score: 5/5
The PR appears safe to merge; no new actionable issues were found.
