Stops unbounded growth of patterns.rvf / brain.rvf. - #495: AbortSignal in HybridMemoryBackend.initialize() so a 5s createHybridBackendWithTimeout abort actually cancels the work instead of leaking a 14-min runaway init (~20 GB / 12 MB/s leak observed in the field). UnifiedMemoryManager.initialize() also accepts {signal} with throwIfAborted() at each await seam. - Post-dream compaction in DreamScheduler — threshold-gated compact() against patterns.rvf and brain.rvf so append-only growth has a steady-state janitor. - Boot-time size guard in getSharedRvfAdapter() for one-shot recovery of installations already in the bad state. - Bounded SQLite→RVF backfill (top-1000 by last_used_at) so `: > patterns.rvf` for disk recovery doesn't trigger an unbounded replay (the "regrew to 59 GB" pathology). - RvfDualWriter.compact() for brain.rvf parity. Three operator env knobs added (no rebuild needed): - AQE_RVF_SIZE_GUARD_BYTES (default 256 MB) - AQE_RVF_DEAD_RATIO_THRESHOLD (default 0.30) - AQE_RVF_BACKFILL_LIMIT (default 1000) 29 new unit tests. Performance gate 15/15 pass. test:ci 4035 pass (3 pre-existing failures, verified identical on main). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
