Running gbrain's own MCP server (67 tools, opinionated naming) and proxying would add a subprocess boundary, complicate auth, and expose tools irrelevant to this use case. Library import gives direct control over tool definitions while leveraging gbrain's storage/search/synthesis internals. Supports US requirement "легко встраивается в сторонние приложения". + +**Alternatives considered:** Proxy gbrain's MCP server and add memory_sign/memory_verify on top — rejected, creates two MCP servers + subprocess management + port conflicts. + +### D2: Bun runtime (required by gbrain) + +**Decision:** Runtime is **Bun ≥1.3.10**. Not Node.js. + +**Rationale:** [TECHNICAL] gbrain uses Bun-specific APIs (Bun.file, Bun.serve, `@electric-sql/pglite` with Bun-compatible WASM loading). PGLite WASM initialization in gbrain's codebase assumes Bun's module resolver. Node.js compatibility cannot be guaranteed without patching gbrain's internals, which we don't own. Bun installs to `~/.bun/` without admin rights — satisfies user-spec zero-admin constraint. + +**Alternatives considered:** Node.js + compatibility shims — rejected, risks breaking PGLite WASM loading and gbrain's internal Bun.file calls. + +### D3: MCP HTTP transport via SSE (Streamable HTTP) + +**Decision:** Cloud mode uses MCP's Streamable HTTP transport (SSE-based), implemented via `Bun.serve`. Port 3456 internally, exposed via nginx HTTPS proxy. + +**Rationale:** [TECHNICAL] MCP specification supports two transports: stdio (local) and Streamable HTTP (remote). SSE-based HTTP is the standard for remote MCP servers that Claude mobile, Kini, KimiClaw all support. `@modelcontextprotocol/sdk` provides `StreamableHTTPServerTransport` for this. + +**Alternatives considered:** WebSocket transport — not standard in MCP SDK v1.x. Plain HTTP without SSE — doesn't support streaming responses from `memory_think`. + +### D4: Single API key for cloud auth (nginx-level) + +**Decision:** Auth is a single static API key checked at nginx level before the request reaches memory-hub. Header: `Authorization: Bearer `. Nginx returns 401 for missing/wrong key. Key stored in nginx config (env-substituted from `.env`). + +**Rationale:** Supports user-spec "один пользователь, один ключ". Checking at nginx keeps memory-hub auth-free (simpler, no auth logic in MCP handlers). Key rotation = update env var + nginx reload (no server restart needed). + +**Alternatives considered:** Auth in memory-hub's HTTP middleware — adds complexity, doesn't change security posture for single-user case. OAuth — out of scope per user-spec. + +### D5: gbrain AI gateway — configureGateway() at startup + +**Decision:** Call gbrain's `configureGateway({ provider, apiKey, model, embeddingModel })` once in `config.ts` before serving requests. Provider is env-driven: `OPENAI_API_KEY` (default), `ANTHROPIC_API_KEY`, or `GOOGLE_API_KEY` — first non-empty wins. + +**Rationale:** [TECHNICAL] gbrain's AI gateway (`src/core/ai/gateway.ts`) must be initialized via `configureGateway()` before any embed/generate call. Gateway supports OpenAI, Anthropic, Google, and OpenAI-compatible providers via Vercel AI SDK (`ai` package + `@ai-sdk/*`). Failing to call it before first use causes a runtime error. Synthesis (`memory_think`) and embedding (`memory_capture`) both require a configured provider. + +**Alternatives considered:** Lazy init per-request — rejected, configureGateway() is designed as a one-time call and uses per-provider module-level caching. + +### D6: PGLite data dir in ~/.universal-memory/brain/ + +**Decision:** Local mode stores PGLite data in `~/.universal-memory/brain/` (user home, no sudo). Configurable via `MEMORY_DATA_DIR` env var. + +**Rationale:** Supports user-spec zero-admin constraint. Userspace write access guaranteed. Path follows XDG convention alternative (not `~/.config` to keep it obvious). Auto-created on first run. + +**Alternatives considered:** `./.universal-memory/` relative to cwd — rejected, different cwd per tool invocation would create multiple separate brains. + +### D7: memory_sign is idempotent by content hash + +**Decision:** Before calling `MnemonicClient.signMemory()`, check if an attestation already exists for this content hash (stored in Postgres alongside the memory entry). If found, return existing `attestationId` without re-signing. + +**Rationale:** Supports user-spec AC "Повторный вызов с тем же id → idempotent". Avoids duplicate Mnemonik calls (which have cost and latency in participate mode). Content hash (blake3, from gbrain's own hash) is the canonical dedup key. + +**Alternatives considered:** Check by memory id only — simpler but breaks if same content stored twice under different ids. + +### D8: Cloud mode requires external Postgres (not PGLite) + +**Decision:** Cloud mode (`MEMORY_BACKEND=cloud`) requires `DATABASE_URL` pointing to an external Postgres 15+ with pgvector extension. PGLite is not used in cloud mode. + +**Rationale:** [TECHNICAL] PGLite is single-writer WASM — not suitable for a long-running HTTP server under concurrent requests. Postgres with pgvector supports HNSW indexes, concurrent reads, and connection pooling. Docker Compose includes a `postgres` service with `pgvector/pgvector:pg16` image. + +**Alternatives considered:** PGLite in cloud — rejected, PGLite's advisory locking model (`pglite-lock.ts` in gbrain) is designed for single-process local use only. + +## Data Models + +### Memory entry (Postgres / PGLite via gbrain's schema) + +gbrain manages its own schema via migrations (`src/core/migrate.ts`). The primary page/chunk tables are gbrain-owned. We add one table: + +```sql +-- Mnemonik attestation index (cloud mode only) +CREATE TABLE IF NOT EXISTS memory_attestations ( + page_id TEXT NOT NULL, -- gbrain page id + content_hash TEXT NOT NULL, -- blake3 hex (gbrain contentHash) + attestation_id TEXT NOT NULL, -- Mnemonik attestationId + signed_at TIMESTAMPTZ NOT NULL, + status TEXT NOT NULL, -- 'signed' | 'anchored' + PRIMARY KEY (page_id) +);

Test suite catches breakage on update. | +| PGLite cold start: 5–20s on first `.connect()` call | Document in README. Wave 1 Task 1 verifies startup time. Optional: `GBRAIN_PGLITE_SNAPSHOT` env var reduces to ~100ms. MCP clients should expect slow first response. | +| PGLite WASM fails to load in Bun (version mismatch) | Wave 1 Task 1 spike: `bun -e "import('@electric-sql/pglite').then(({PGlite}) => new PGlite(':memory:').then(db => db.query('SELECT 1')))"` — fail fast before any tool work. | +| `runThink()` from `gbrain/think` not yet imported | Task 5 adds the import. If gbrain's think module is not exported as a library path, workaround: copy the function signature and call engine search + gateway directly. | +| gbrain `configureGateway()` called before module init (ordering issue) | Call in `config.ts` at import time (module-level), before server.listen(). Test: startup with no LLM key → clear error message, not a runtime crash mid-request. | +| Mnemonik JWT expiry (24h TTL) | `parseJwtPayload(jwt)` at startup; if expired → log warning but don't crash (signing tools return "JWT expired, re-run npx @mnemonik-xyz/cli login"). | +| `memory_think` latency (LLM call) | Expected 2-10s. MCP clients should handle this. Document in README. Post-MVP: streaming response via SSE. | +| pgvector extension not available on Postgres image | Use `pgvector/pgvector:pg16` Docker image (pre-installed). Verify in Wave 5 infra task. | +| LLM API key required for local mode (embedding needs it) | Document clearly: local mode requires `OPENAI_API_KEY` (or equivalent) for embedding. `memory_capture` without key → clear error: "LLM API key required for embedding. Set OPENAI_API_KEY." | +| gbrain's chunker/embedder API not stable as library | Wave 1 spike imports gbrain/ingestion and calls it — fail fast if API mismatch. Fallback: use gbrain's own `put_page` operation abstraction. | + +## User-Spec Deviations + +### DEV-1: LLM API key required for local mode [PENDING USER APPROVAL] + +**User-spec says:** "Работает без прав администратора — никакого sudo, никаких системных сервисов, никаких глобальных установок." + +**Tech-spec does differently:** Local mode requires an LLM API key (`OPENAI_API_KEY` or `ANTHROPIC_API_KEY` or `GOOGLE_API_KEY`) for both embedding (memory_capture) and synthesis (memory_think). The key itself has no install cost — but it is an external dependency not mentioned in user-spec. + +**Why:** gbrain's engine uses vector embeddings for hybrid search. Without embeddings, search and synthesis don't work. PGLite is zero-setup; the LLM API key is not. + +**Mitigation options:** +- Option A (recommended): local mode falls back to BM25-only search if no key set; synthesis returns error "LLM key required for synthesis". Allows zero-key basic search. +- Option B: use a local embedding model (Ollama/fastembed) — more complex, adds binary dependency. +- Option C: require key, document clearly — simplest but breaks the zero-external-dependency promise. + +### DEV-2: memory_sign requires Mnemonik JWT (external service) [TECHNICAL] + +User-spec describes `memory_sign` as a tool. Implementation requires `MNEMONIC_JWT` from `https://mnemonik.xyz/install` — a one-time setup step not mentioned in user-spec flows. This is a pre-condition, not a behavioral change. Documenting as `[TECHNICAL]` — setup cost, not a deviation in functionality. + +## Acceptance Criteria (technical complement) + +- [ ] `cd /home/op/Projects/universal-memory && bun install` succeeds without sudo. +- [ ] `bun run packages/memory-hub/src/mcp/server.ts` starts in local mode, prints "Universal Memory Hub ready (local/PGLite)" to stderr. +- [ ] `bun test packages/memory-hub/` — all unit + integration tests pass. +- [ ] PGLite initializes in `~/.universal-memory/brain/` (or `MEMORY_DATA_DIR`) on first run. +- [ ] Cloud mode: `docker compose up memory-hub postgres -d` starts both services; nginx `memory.` subdomain returns 401 on missing auth. +- [ ] Cloud mode: correct Bearer → MCP tools/list returns 7 tools. +- [ ] DEV-1 resolution implemented (Option A or B or C, per user decision). + +## Implementation Tasks + +### Wave 1 — Foundation + config (parallel) + +#### Task 1: config.ts + gbrain gateway init + LocalAdapter synthesis + +**Description:** Three tightly coupled gaps to close together.

The gbrain submodule ships without a `./think` export entry in its `package.json`, which means any `import ... from 'gbrain/think'` fails at module resolution before a single line of synthesis code runs — patching this first ensures all downstream tasks can import the function they need without workarounds. Without this patch the synthesis path is structurally broken from the start. + +`config.ts` is the single place where the AI gateway is configured and the operating mode is decided. It must run at module-load time so that embedding and LLM calls work on the very first request. The file implements the DEV-1 resolution: it probes for `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, and `GOOGLE_API_KEY` in order — first non-empty wins and `configureGateway()` is called with that provider. If none are found it checks whether Ollama is reachable at `localhost:11434` and configures the OpenAI-compatible provider against it. If neither cloud keys nor Ollama are present the server still starts, but in BM25-only fallback mode: a startup warning is printed to stderr and synthesis calls return a human-readable message pointing to `bunx universal-memory setup`. This satisfies the user-spec zero-configuration local-mode requirement while preserving a clear upgrade path. + +`LocalAdapter.synthesize()` is the concrete implementation of `memory_think` for local mode. Wiring it means importing `runThink` from `gbrain/think` (possible only after the package.json patch above), calling it with the PGLite engine and the user's question, and mapping the returned `ThinkResponse` — which contains `ParsedCitation[]` with slug-based references — to the tool output shape `{ answer, citations: [{id, excerpt}], gaps }`. The fourth sub-task confirms PGLite engine creation via `createEngine({ engine: 'pglite', dataDir })` from `gbrain/engine-factory`; this is a smoke check that the submodule is wired correctly before Wave 2 and 3 tasks build on top of it. + +## What to do + +1. **Read the source files first** — before writing any code, read: `vendors/gbrain/package.json` (current exports map), `vendors/gbrain/src/core/think/index.ts` (exported names, `ThinkResponse` type, `ParsedCitation` shape), `vendors/gbrain/src/core/ai/gateway.ts` (`configureGateway()` signature and supported providers), `vendors/gbrain/src/core/engine-factory.ts` (`createEngine()` signature, `EngineKind` union), `vendors/gbrain/src/core/pglite-engine.ts` (constructor options, `.connect()`, `.initSchema()`, `.kind` getter), `packages/memory-hub/src/storage/local.ts` (existing `LocalAdapter` class and `synthesize()` stub). + +2. **Patch `vendors/gbrain/package.json`** — add the `"./think"` export entry to the `"exports"` map: + ```json + "./think": "./src/core/think/index.ts" + ``` + Verify no existing entry for `./think` to avoid duplication. Keep all other exports intact. + +3. **Write `packages/memory-hub/src/config.ts`** — new file, module-level side effects: + - Read env vars: `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GOOGLE_API_KEY`, `OLLAMA_BASE_URL` (fallback: `http://localhost:11434`), `MEMORY_BACKEND`, `MEMORY_DATA_DIR`. + - Priority check: first non-empty of `OPENAI_API_KEY` → `ANTHROPIC_API_KEY` → `GOOGLE_API_KEY`. If found, call `configureGateway({ provider, apiKey, model, embeddingModel })` and set `export const mode = 'full'`. + - Else: probe Ollama via `fetch(`${ollamaBase}/api/tags`, { signal: AbortSignal.timeout(2000) })`. If reachable, call `configureGateway()` with OpenAI-compatible provider pointing at Ollama base URL; set `export const mode = 'ollama'`. + - Else: set `export const mode = 'bm25-only'`. Print startup warning: `[universal-memory] Running in BM25-only mode. For semantic search, set OPENAI_API_KEY or run setup.` — print to `stderr`, not `stdout` (MCP uses stdout for JSON-RPC). + - Export `export const dataDir` (resolves `~` in `MEMORY_DATA_DIR` or defaults to `~/.universal-memory/brain/`). + - Never log raw values of `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GOOGLE_API_KEY`. Startup log (when key found) prints: `provider: openai, key: sk-...XXXX` (last 4 chars only). Add `scrubSecrets(s: string): string` helper that redacts `Bearer `, `sk-...` patterns, and JSON keys `keypair`/`jwt` — export it for reuse in other modules (D13). + - Export `export function getConfig()` returning the resolved config object (mode, dataDir, provider, ollamaBaseUrl) — useful for testing without re-running module-level side effects. + +4. **Wire `LocalAdapter.synthesize()`** in `packages/memory-hub/src/storage/local.ts`: + - Import `runThink` from `gbrain/think` (the patched export). + - In `synthesize({ question })`: check `mode` from `config.ts` — if `bm25-only`, return `{ answer: "Synthesis requires LLM.

Created `packages/memory-hub/src/config.ts` with module-level AI gateway init (OpenAI → Anthropic → Google → Ollama → BM25-only fallback), `scrubSecrets()` log helper, and `dataDir` resolution with `~` expansion. Wired `LocalAdapter.synthesize()` to call `runThink(engine, { question })` and map `ThinkResult.citations: ParsedCitation[]` (`{ page_slug, row_num, citation_index }`) to `{ id: page_slug, excerpt: slug#row }`. Created `engine/pglite.ts` wrapper calling `createEngine({ engine: 'pglite', database_path })` (NOTE: gbrain uses `database_path`, not `dataDir`). Added `setup.ts` CLI hint and `"setup"` script to package.json. + +**Key decisions:** `ParsedCitation.page_slug` maps to `id` and `slug#row_num` format for `excerpt` (row_num is the take index, null = page-level citation). `configureGateway()` receives full `process.env` snapshot as the `env` field (matches gbrain's existing pattern from cli.ts). `SynthesisResult` interface is canonical in `storage/index.ts` (not duplicated in `local.ts`). BM25-only mode returns valid tool output shape (not thrown), preventing MCP tool errors. + +**Deviations from spec:** `createEngine()` parameter is `database_path` (not `dataDir`) — confirmed from `EngineConfig` type in `vendors/gbrain/src/core/types.ts`. The `PGLiteEngine.connect()` accepts an empty object `{}` (not null/undefined). Anthropic config branch omits embedding model (Anthropic has none) — Wave 2 will handle embedding config per-provider.

BM25-only mode returns valid tool output shape (not thrown), preventing MCP tool errors. **Deviations from spec:** `createEngine()` parameter is `database_path` (not `dataDir`) — confirmed from `EngineConfig` type in `vendors/gbrain/src/core/types.ts`. The `PGLiteEngine.connect()` accepts an empty object `{}` (not null/undefined). Anthropic config branch omits embedding model (Anthropic has none) — Wave 2 will handle embedding config per-provider. + +## Task 2: HTTP MCP transport + Bearer auth + +**What was done:** Created `mcp/auth.ts` with `validateBearer()` using `crypto.timingSafeEqual()` (D10). Zero-padding trick: both token buffers are zero-padded to `max(len_a, len_b)` so `timingSafeEqual` never throws on length mismatch, and a separate `lengthsMatch` boolean prevents false positives. Created `mcp/http.ts` with `startHttpServer()` using `WebStandardStreamableHTTPServerTransport` (Bun-native Web Standard API, NOT the `StreamableHTTPServerTransport` Node.js wrapper). Auth middleware runs before MCP dispatch; `/health` endpoint bypasses auth. Fetch handler wrapped in try/catch so unhandled promise rejections return 500 JSON (not process crash). Implemented `CloudAdapter` stub in `storage/cloud.ts` that allows the HTTP server to start without `DATABASE_URL` (warns at startup, throws on tool use) — full implementation is Task 5. Updated `server.ts` mode selector: `MEMORY_BACKEND=cloud` starts HTTP, `local` (default) starts stdio. Startup log never prints `MEMORY_API_KEY` value (D13). + +**Key decisions:** +- **MCP SDK HTTP transport class:** `WebStandardStreamableHTTPServerTransport` (NOT `StreamableHTTPServerTransport`). The latter wraps Node.js `IncomingMessage/ServerResponse` via `@hono/node-server` and should not be used with Bun. The Web Standard variant accepts `Request` and returns `Response` natively — perfect for `Bun.serve`. +- **Stateless mode:** `sessionIdGenerator: undefined` — single-user deployment, no session state needed. This simplifies the transport and avoids session ID overhead. +- **Zero-padding for timingSafeEqual:** Both buffers padded to `max(len)` with `Buffer.alloc(maxLen)` then `copy()`. This prevents `timingSafeEqual` from throwing on length mismatch AND prevents an attacker from learning the key length via exception timing. The separate `lengthsMatch` check ensures a short token that happens to match after padding is still rejected. +- **CloudAdapter deferred throw:** Constructor accepts `undefined` DATABASE_URL (prints warning), methods call `requireDb()` which throws with actionable message. Allows `MEMORY_BACKEND=cloud MEMORY_API_KEY=test123` (no DB URL) to start the HTTP server and serve auth checks for smoke testing. + +**Smoke verified:** +- `MEMORY_BACKEND=cloud MEMORY_API_KEY=test123` → server starts, logs `(set)` for key, never the value +- `curl -H "Authorization: Bearer wrong"` → `401 {"error":"unauthorized",...}` +- `curl -H "Authorization: Bearer test123"` + initialize → SSE event with MCP initialize response + +**Deviations from spec:** The spec referenced `vendors/gbrain/src/mcp/serve-http.ts` as a pattern — this file does not exist. The actual reference file is `vendors/gbrain/src/mcp/http-transport.ts`. Used `WebStandardStreamableHTTPServerTransport` (the Bun-native class) instead of `StreamableHTTPServerTransport` (Node.js wrapper) as documented in the MCP SDK type definitions.
