Architecture

Driver: modernc.org/sqlite (pure-Go, no CGO, cross-compile-clean).
Store: SQLite WAL + open-string pragmas (busy_timeout=5000, cache=shared, synchronous=NORMAL).
Connection pools: 1 writer (single conn) + 8 readers (read-only opens).
Retrieval: prepared statement + composite index (surface, ts DESC).
Capture: fsnotify per-surface watchers + incremental parsers + offset-state in ~/.eidetic/state.json.
Lifecycle: spawn-at-app-startup mandatory (absorbs 1.75s modernc cold-init behind app load).

Privacy posture

Engrams never leave your machine without an explicit user action. Every network call the daemon makes is opt-in. See the security policy for the full audit table, and ADR-020 in the source repo for the lock-in contract.
