v0.2.2

0.2.2 (2026-06-10)

Bug Fixes

• rag: sanitize FTS5 MATCH query so special characters don't crash retrieval (#64) (efbdea0), closes #63

v0.2.1

⚠️ Deprecated — ambient memory is non-functional in this release. A query-sanitization bug (#63) makes the grounding daemon error on most natural-language prompts, so the engram-memory plugin injects nothing. Fixed in v0.2.2; upgrade to v0.2.2 or later. The MCP server, daemons, and retrieval tools themselves are unaffected.

0.2.1 (2026-06-10)

Features

• db: schema/embedding-dimension compatibility guard + eos-version (83079bd)

Documentation

• restructure README + add documentation index (fb4322e)

v0.2.0

⚠️ Deprecated — ambient memory is non-functional in this release. A query-sanitization bug (#63) makes the grounding daemon error on most natural-language prompts, so the engram-memory plugin injects nothing. Fixed in v0.2.2; upgrade to v0.2.2 or later. The MCP server, daemons, and retrieval tools themselves are unaffected.

Ambient memory, durability tooling, and a Docker install.

Added

• Ambient memory — a new engram-rag grounding daemon (HTTP) + the engram-memory Claude Code plugin: auto-injects relevant memory each turn (UserPromptSubmit), primes each session (SessionStart), records grounded-in citations (Stop), with a companion behavioral skill. Retrieval is calibrated to a STRONG/WEAK/NONE verdict so it stays quiet when nothing relevant exists.
• Session priming & reflection — session.prime seeds a session with goals + high-confidence memory; session.reflect (+ eos-reflect) surfaces unresolved contradictions, stale high-value entries, and idle goals. Deterministic, no model calls.
• Citation-weighted ranking — rag.cite + a content_usage table weight cited entries up in later retrieval.
• rag.query calibration & scoping — returns a verdict with results; accepts token_budget, level, and since.
• Backup / verify / restore — eos-snapshot, eos-verify (content-hash + integrity invariants), eos-restore (verify-first, backup-first, typed confirmation).
• Source health — sources.health tool + eos-source health CLI.
• Docker install — full stack via docker compose (MCP HTTP transport + daemons + private SearXNG); provider-agnostic LLM via ENGRAM_LLM_*.
• Uninstall — eos-uninstall (native or Docker) with optional database export.
• Schema migrations 003 (grounding / content_usage) and 004 (content.protected).

Changed

• sentence-transformers moved to an optional [rag] extra (numpy promoted to core). Real installs (eos-init, Docker) pull [rag]; a bare core install is torch-free.
• rag.query response now wraps results with a calibration verdict: {verdict, results}.

Fixed

• Human edits are no longer silently clobbered (#37) — the poller preserves an upstream change as a non-current revision and raises a contradiction instead of overwriting a human-edited sourced file.
