# Production incident records

**All incidents here are resolved.** They were previously top-level `BUG-*.md`
files whose status headers still read "Open", which is no longer true. The
lessons are folded into `CLAUDE.md`; these are the long-form originals.

| File | Resolution |
|------|-----------|
| `2026-04-19-snapshot-truncation.md` | **Fixed in v1.6.1.** The snapshot writer became atomic - write `.tmp`, fsync, rename, then verify by re-reading. A loader fallback chain and the MySQL-style recovery modes landed with it. |
| `2026-04-22-zoe-rss-exceeds-budget.md` | **Superseded by v2.0.** The original "memory leak" framing was wrong: v2.4.3 established that `estimatedMemoryBytes_` under-reports by roughly 5x, so eviction never believed it had made progress. Since v2.0 RSS is bounded by the LMDB mapsize plus OS page cache, not by MemoryStore eviction, and `max_memory_mb` only sizes the mirror cache. |
| `2026-04-22-eviction-induced-write-loss-plan.md` | **Shipped in v1.7.x.** Became chunked pressure-aware eviction (four pressure levels, hot-write floor, quiesce on in-flight writes, no per-collection mutex held during disk I/O) plus the `conf.d` drop-in config mechanism. v2.4.3 later added the episode cap and no-progress detector after eviction drained a live store. |

Anything still open lives in `docs/ROADMAP.md` under "Pending", not here.
