Gentleman-Programming/engram v0.1.8

on GitHub

Highlights

• Added full observation lifecycle tools: mem_update and mem_delete (soft-delete by default, hard-delete optional).
• Added scoped memory with scope (project / personal) across save, search, context, recent lists, and API filters.
• Added topic-based memory upserts with topic_key + revision_count so evolving decisions update in place instead of creating duplicates.
• Added mem_suggest_topic_key to generate stable topic keys with family heuristics (architecture/*, bug/*, decision/*, etc.).

What's Included

• Store/DB migration (idempotent) for new observation fields and indexes:
  • scope, topic_key, revision_count, normalized_hash, duplicate_count, last_seen_at, updated_at, deleted_at.
• Deduplication safeguards:
  • Exact dedupe by normalized content hash + project + scope + type + title (rolling window).
  • Topic upsert by project + scope + topic_key with revision tracking.
• MCP tools expanded to 13 tools:
  • Added mem_update, mem_delete, mem_suggest_topic_key.
• HTTP API updates:
  • PATCH /observations/{id} and DELETE /observations/{id}.
  • Scope filters on search/context/recent endpoints.
• Plugin/docs updates for both OpenCode and Claude Code memory protocols.

Quality

• Added/expanded tests:
  • Unit tests for store topic/dedupe/scope/update/delete behavior.
  • Unit tests for MCP topic suggestion and save behavior.
  • E2E HTTP tests for topic upsert + delete/search flow.
• Full test suite passing (go test ./...).

Notes

• No breaking changes for existing mem_save flows; defaults remain backward compatible (scope=project).
• Existing databases are migrated automatically on first run of this version.
