rdmbair15m5 - changelog - replicantdb-fsevents-governor-pause-accumulation - claude - unspecified - general - 20260916-1604

Routed all four ReplicantDB pause paths (memory, thermal, battery/power, and index pressure/directives) through HeldEventAccumulator to prevent silent FSEvents batch dropping, and verified with 1,350 test passes (ISSUE-20260906-01).

Scope

• Host: rdmsm4x (canonical dev root), rdmbair15m5
• Repo: apps/replicantDB, issues
• Ticket: ISSUE-20260906-01

Exact Files Touched

• apps/replicantDB/Sources/ReplicantDBDaemon/DaemonService.swift:
  • Unified batch admission logic in admitOrAccumulate(directories: [URL]) async -> PressureDecision? to check memory pressure/footprint, thermal critical state, and battery status (!isOnACPower && !config.indexOnBattery) before index pressure / quiesce directives.
  • Ensured every pause path calls heldEvents.accumulate(directories) rather than dropping the batch.
  • Added isAnyGovernorPaused() async -> Bool helper.
  • Added governor pause check inside drainHeldEvents() loop to immediately halt draining if any governor enters a pause state during multi-batch draining.
• apps/replicantDB/Sources/ReplicantDBDaemon/ThermalGovernor.swift:
  • Added setOverrideThermalState(_ state: ProcessInfo.ThermalState?) test override hook with hysteresis clearance.
• apps/replicantDB/Sources/ReplicantDBDaemon/MemoryGovernor.swift:
  • Added setOverridePressure(_ pressure: Pressure?) test override hook for kernel memory pressure simulation.
• apps/replicantDB/Sources/ReplicantDBDaemon/PowerGovernor.swift:
  • Added setOverridePowerState(_ snapshot: PowerSourceSnapshot?) test override hook for AC/battery status simulation.
• apps/replicantDB/Tests/ReplicantDBTests/CooperativeQuiesceDaemonTests.swift:
  • Added testThermalPauseAccumulatesAndDrainsOnResume: verifies critical thermal state pauses admission, accumulates batch, and drains on cooldown to nominal.
  • Added testMemoryPauseAccumulatesAndDrainsOnResume: verifies critical memory pressure pauses admission, accumulates batch, and drains on recovery to normal.
  • Added testBatteryPauseAccumulatesAndDrainsOnResume: verifies battery operation (indexOnBattery=false) pauses admission, accumulates batch, and drains on AC power resumption.
  • Added testADrainStopsWhenThermalGovernorEntersCriticalStatePartwayThrough: verifies mid-drain pause stops processing after the first bounded batch and leaves remaining events safely queued in accumulator.
