Snippets are exact-name-keyed templates (PR formats, checklists, style
rules) — prescriptive artifacts the user wants applied consistently.
Distinct from memories, which are searched descriptive prose.
- Migration 0002 adds scope/project_id/deleted_at to snippets, partial
unique indexes per scope, and a scope/project CHECK constraint
mirroring memories_scope_project_chk.
- New @shared-memory/schemas: SnippetName/Put/Get/List/Delete inputs
with shared scope-project refinement.
- lib/snippets.ts: get/put/list/softDelete helpers used by both the
Web Server Actions and the MCP tool handlers.
- Four new MCP tools (snippet.put/get/list/delete) with directive
descriptions contrasting against memory.* (exact-name lookup vs
search; templates vs facts).
- /snippets pages: list, new, [name] with edit + delete and a
scope-picker when a name lives in multiple scopes.
- Nav: Snippets link between Memories and Projects.
Design note: when a name exists in both user and project scope,
snippet.get without an explicit scope prefers project (if project key
given) then falls back to user. The detail page shows a picker when
the name is ambiguous and no scope query param was supplied.

Adds a small embedder sidecar (Xenova/bge-small-en-v1.5, ONNX, CPU-only)
that the web app calls inline on memory.write and memory.update, and on
demand from the new memory.search tool.
memory.search performs three candidate fetches in parallel — pgvector
cosine similarity, Postgres full-text via plainto_tsquery + ts_rank_cd,
and tag-set overlap — then fuses them with Reciprocal Rank Fusion
(k=60). Each result carries its per-source rank so the model can see
*why* a memory surfaced.
The migrator boot step gained an idempotent embedding backfill: any row
with embedding IS NULL is batched (32 at a time) through the embedder
after SQL migrations apply. Safe to run on every boot.
New tool memory.update fixes the missing edit path; centralises the
re-embed-on-content-change rule alongside write.
Stack additions:
- apps/embedder/ — Fastify server, persistent /data/models volume so the
~30 MB model only downloads once
- apps/web/lib/embedder.ts — typed HTTP client with batched embed +
health probe
- packages/schemas — MemoryUpdateInput, MemorySearchInput
- docker-compose — embedder service, healthcheck, app + migrator both
depend_on it healthy; EMBEDDER_URL promoted to a required env var

End-to-end Phase 1 of shared-memory: a logged-in Authentik user can sign
into the Web UI (/me debug page), and an MCP client with an Authentik-
issued bearer token can call memory.write / memory.list / memory.get /
memory.delete plus project.identify against /api/mcp.
Stack:
- Next.js 15 (App Router) + React 19 + TypeScript, pnpm workspaces
- Drizzle ORM + Postgres 16 + pgvector + pg_trgm
- Auth.js v5 with Authentik provider (Web UI)
- jose + Authentik JWKS for MCP bearer-token validation
- JSON-RPC 2.0 dispatcher implementing the MCP wire protocol over plain
HTTP POST (hand-rolled to fit Next.js App Router; switches to SSE in a
later phase if server-initiated events are needed)
- bge-small embeddings sidecar deferred to Phase 2; the schema already
reserves the vector(384) column + IVFFlat index, FTS via a STORED
tsvector column, and the visibility enum (private/shared/team) so
cross-user memory sharing can be added without a future migration
Deployment supports two modes (set in .env, never committed):
- Behind an external reverse proxy (HAProxy / nginx / Cloudflare Tunnel /
Traefik) — DEFAULT; the app exposes APP_PORT on the host with
X-Forwarded-* trusted, no in-container TLS
- Built-in TLS via Caddy — opt-in with `docker compose --profile tls up`
Discovery endpoint at /.well-known/oauth-protected-resource (RFC 9728)
points MCP clients at the Authentik authorization server after a 401.
README walks through both Authentik providers (Web UI + MCP resource
server), the audience scope mapping, redirect URIs, and includes a worked
HAProxy config snippet.
