## M001-6377a4: Consolidate Memory Systems into Unified node:sqlite Store
**Gathered:** 2026-05-07
**Status:** Ready for planning
## Project Description
Replace three fragmented memory systems with a single unified store backed by `node:sqlite`. All memory ingestion, querying, and prompt injection flows through one canonical database table in `sf.db`.
**Three systems being consolidated:**
1. **`memory-store.js`** (SF, `src/resources/extensions/sf/memory-store.js`) — function-based API backed by `sf-db.js``node:sqlite``sf.db`. Already uses `node:sqlite`. Exports: `createMemory`, `updateMemoryContent`, `reinforceMemory`, `supersedeMemory`, `getActiveMemoriesRanked`, `getRelevantMemoriesRanked`, `formatMemoriesForPrompt`. Tables: `memories`, `memory_embeddings`, `memory_relations`, `memory_processed_units`.
2. **Memory extension** (`packages/pi-coding-agent/src/resources/extensions/memory/`) — LLM-based session transcript extraction that writes to `agent.db` via `sql.js` (WASM SQLite). Pipeline: scan → filter → phase1 LLM extraction → phase2 consolidation → `MEMORY.md` output.
3. **`knowledge-injector.js`** (SF, `src/resources/extensions/sf/knowledge-injector.js`) — parses markdown knowledge entries and injects into prompts via semantic similarity matching. Called by prompt assembly before agent start.
## Why This Milestone
**What problem this solves:** Three parallel memory systems create maintenance fragmentation, competing injection paths into system prompts, and two SQLite implementations (`node:sqlite` in SF + `sql.js` WASM in pi-coding-agent). Adding a `source` column and wiring all paths to `sf.db` eliminates the duplication and provides a single canonical store.
**Why now:** The existing `memory-store.js` is already well-designed. The migration and wiring work is tractable. Post-consolidation, future memory features (embedding reranking, relation boosting) have one place to land.
## User-Visible Outcome
### When this milestone is complete, the user can:
- Run `/memory view` and see memories from `sf.db` (not from `agent.db` or `MEMORY.md`)
- Trigger `/memory rebuild` and watch extraction write directly to `sf.db`
- Invoke the `capture_thought` tool and see it persist to `sf.db` with a source tag
- Query memories via `memory_query` and receive ranked results via cosine + relation boost
### Entry point / environment
- Entry point: `sf` CLI, `/memory` command, `capture_thought` and `memory_query` tool calls
- Environment: local dev, CI, production (single-user, per-project sf.db)
- Live dependencies: LLM provider (for extraction), `node:sqlite` (built-in Node >= 24)
## Completion Class
- **Contract complete** means: `sf.db` `memories` table passes CRUD + ranking tests; `capture_thought` and `memory_query` are registered native tools with schema validation; migration script has dry-run + backup modes.
- **Integration complete** means: session transcript pipeline writes to `sf.db`; `/memory` command reads from `sf.db`; all three legacy paths are removed or no-op'd.
- **Operational complete** means: WAL contention does not block session startup (extraction is fire-and-forget); no memory-related background processes leak resources.
## Final Integrated Acceptance
To call this milestone complete, we must prove:
- **Behavioral regression test passes:** A Playwright or shell test starts a session, triggers extraction, and verifies `/memory view` shows entries from `sf.db` — not `agent.db` or `MEMORY.md`.
- **`grep` verification passes:** `grep -r "sql.js|better-sqlite3" src/ packages/ --include="*.ts" --include="*.js" | grep -v "test\|spec\|deprecated"` returns zero matches in memory-related code paths.
- **`capture_thought`/`memory_query` are native tools:** Registered with proper TypeBox schema, validated in tool registry tests.
## Architectural Decisions
### Use function-based API, not a class wrapper
**Decision:** Extend the existing `memory-store.js` function-based API rather than wrapping it in a `MemoryStore` class.
**Rationale:** The existing functions (`createMemory`, `getRelevantMemoriesRanked`, etc.) are already the right abstraction. Adding a class wrapper introduces churn with no clear benefit — the pipeline can call functions directly. This minimizes risk during consolidation.
**Alternatives Considered:**
- Class wrapper (`MemoryStore` class) — higher churn, no functional benefit; rejected.
### Add `source` column to `memories` table
**Decision:** Add a `source` column (`'capture' | 'extracted' | 'migrated' | 'manual'`) to distinguish ingestion paths.
**Rationale:** Different sources have different confidence defaults and maintenance semantics. `capture_thought` entries start at confidence 0.8; extracted memories start at 0.7; migrated entries preserve original confidence. The column enables source-filtered queries and targeted deduplication.
### Register `capture_thought` and `memory_query` as native pi tools
**Decision:** Register `capture_thought` and `memory_query` as native pi tools (like `vectordrive_store`) with TypeBox parameter schemas, rather than relying solely on LLM tool-call convention in prompts.
**Rationale:** Native tool registration provides: (1) proper schema validation, (2) tool descriptions surfaced to the LLM, (3) consistent error handling. The current approach (LLM calls named tools in prompts) is fragile — the tool isn't actually registered, so errors are silently dropped.
**Alternatives Considered:**
- LLM tool-call convention only — already works but fragile; no schema validation; rejected.
### Keep `memory_embeddings` table as-is
**Decision:** Leave the existing `memory_embeddings` table in `sf.db` (BLOB storage for vectors) and the associated `memory-embeddings.js` / `memory-embeddings-llm-gateway.js` modules unchanged.
**Rationale:** The embedding infrastructure is pre-existing and functional. The consolidation goal is storage/unification, not embedding redesign. Wiring to VectorDrive is a future optimization, not required for this milestone.
**Alternatives Considered:**
- Wire embeddings to VectorDrive — VectorDrive has Rust SQLite vector support, but it is a separate system; adds complexity; deferred to a future milestone.
- Pure JS vector similarity — viable for small scale, but the existing infrastructure is sufficient.
### Migrate `agent.db` in S03, delete after import
**Decision:** S03 migration script reads `agent.db` stage1_outputs, imports memories to `sf.db` with `source='extracted'`, then deletes `agent.db`.
**Rationale:** Deleting after successful import is the cleanest cutover. Keeping the file around creates dual-write risk and user confusion. Dry-run mode + automatic `sf.db` backup mitigate migration risk.
**Alternatives Considered:**
- Delete at end of S04 — leaves dual-write window open longer; rejected.
- Leave orphaned (don't delete) — leaves cruft; rejected.
### Full scope: SF + pi-coding-agent
**Decision:** Consolidate both SF's `memory-store.js`/`knowledge-injector.js` AND pi-coding-agent's memory extension into `sf.db`.
**Rationale:** The memory extension's extraction pipeline is the primary source of extracted memories. If it still writes to `agent.db`, the consolidation is incomplete. Porting it to write to `sf.db` via `MemoryStore` is the correct scope.
## Error Handling Strategy
- **DB unavailable:** All `memory-store.js` functions degrade gracefully — return `[]` / `null` / `false` instead of throwing. `capture_thought` tool returns an error message, not a crash.
- **Migration failures:** S03 script skips corrupted records with a warning, continues processing remaining entries, and reports final counts. Never partially migrates without reporting.
- **LLM extraction failures:** Session startup extraction runs fire-and-forget; errors are caught and logged but do not block dispatch.
- **Token budget overflow:** `formatMemoriesForPrompt` respects `tokenBudget` parameter (~4 chars/token) and truncates at budget. Category grouping preserves priority order (gotcha → convention → architecture → pattern → environment → preference).
## Risks and Unknowns
- **Data loss during migration** — Users may have valuable accumulated memories in `agent.db` and `KNOWLEDGE.md` that would be lost if migration fails. **Mitigation:** Dry-run mode reports counts without modifying DB; automatic backup of `sf.db` before migration; skip-on-error with warning for corrupted records.
- **WAL contention on `sf.db`** — The `sf.db` already has a single-writer invariant. Adding memory extraction writes during session startup could create lock contention. **Mitigation:** Extraction runs fire-and-forget (does not block dispatch). If contention occurs, the single-writer invariant ensures serialized writes.
- **Breaking memory extension API contract** — The memory extension is a Pi extension with hooks and commands. Changing its storage backend changes observable behavior for external consumers. **Mitigation:** The `/memory` command output format is preserved; migration script ensures no data loss.
- **`capture_thought`/`memory_query` registration scope** — These tools should be registered in the pi-agent-core tool registry. The registration point needs to be identified before S01 implementation.
- **Node.js version requirement**`node:sqlite` (DatabaseSync) requires Node >= 24. The project currently documents this as a minimum version. No change needed.
## Existing Codebase / Prior Art
- `src/resources/extensions/sf/memory-store.js` — Source of truth for the existing function-based API; already uses `node:sqlite` via `sf-db.js`. **Not to be rewritten; extended.**
- `src/resources/extensions/sf/sf-db.js` — Single-writer SQLite adapter using `node:sqlite` DatabaseSync. **Already correct; no changes needed.**
- `src/resources/extensions/sf/memory-embeddings.js` — LLM gateway for embedding computation. **Pre-existing; out of scope.**
- `src/resources/extensions/sf/memory-embeddings-llm-gateway.js` — Cross-encoder reranking. **Pre-existing; out of scope.**
- `packages/pi-coding-agent/src/resources/extensions/memory/storage.ts``sql.js`-based `MemoryStorage` class. **Replaced in S02.**
- `packages/pi-coding-agent/src/resources/extensions/memory/pipeline.ts` — Two-phase extraction pipeline. **Ported to `sf.db` in S02.**
- `src/resources/extensions/vectordrive/` — Rust N-API vector database. **Pre-existing; embedding integration deferred to future milestone.**
- `src/resources/extensions/sf/knowledge-injector.js` — Markdown knowledge parser and semantic similarity. **Removed or no-op'd in S03.**
## Relevant Requirements
- **Unified memory storage** — Covered: all three systems consolidate into `sf.db`.
- **Semantic search** — Covered: `getRelevantMemoriesRanked` with cosine + relation boost + optional rerank.
- **Session-based learning** — Covered: extraction pipeline ports to `sf.db` in S02.
- **Cross-session context persistence** — Partially covered: memories survive across sessions via `sf.db`. Multi-project sharing deferred.
## Scope
### In Scope
- Add `source` column to `memories` table in `sf.db`
- Register `capture_thought` and `memory_query` as native pi tools with TypeBox schemas
- Port memory extension extraction pipeline from `sql.js`/`agent.db` to `sf.db` via `memory-store.js` functions
- Migration script: `KNOWLEDGE.md``sf.db` and `agent.db``sf.db`
- Behavioral regression test (shell/Playwright) for end-to-end verification
- Remove or no-op `knowledge-injector.js` after migration
- Remove `sql.js` dependency from `packages/pi-coding-agent`
- Remove `memory_embeddings` table and embedding code **NOT in scope** — pre-existing, functional
### Out of Scope / Non-Goals
- Redesigning the embedding infrastructure (VectorDrive wiring, pure-JS vectors) — deferred to future milestone
- Multi-project memory sharing or cloud sync
- Changing the `memory-embeddings.js` / `memory-embeddings-llm-gateway.js` modules
- Changing `sf-db.js` schema initialization logic
- Supporting Node < 24
## Technical Constraints
- **Node >= 24 required**`node:sqlite` DatabaseSync is built-in since Node 24. Earlier versions would need a polyfill or different approach.
- **Single-writer invariant on `sf.db`**`sf-db.js` is the only writer. Memory functions must go through the adapter, not direct SQL.
- **`sql.js` WASM bundle** — Currently in `packages/pi-coding-agent/package.json`. Removing it requires updating the build output and verifying no other packages depend on it.
## Integration Points
- **LLM provider** — Extraction pipeline calls `completeSimple` for phase 1 (memory extraction) and phase 2 (consolidation). No API key changes needed.
- **`sf.db`** — Canonical store. Schema already has `memories` table; only needs `source` column added.
- **`agent.db`** — Legacy store. Migrated in S03, then deleted.
- **`KNOWLEDGE.md`** — Legacy file. Migrated in S03, then read-only fallback (removed from injection path).
- **pi-coding-agent package** — Owns the extraction pipeline and `/memory` command. S02 rewires it to `sf.db`.
- **VectorDrive** — Pre-existing vector DB. Embedding integration deferred.
## Testing Requirements
- **Unit tests (S01):** CRUD operations on `memories` table, ranking formula (`confidence * (1 + hit_count * 0.1)`), source filtering, graceful degradation when DB unavailable, `formatMemoriesForPrompt` truncation and category grouping.
- **Contract tests (S02):** Pipeline writes to `sf.db` with correct `source` value; `/memory view` reads from `sf.db`; fire-and-forget does not block dispatch.
- **Migration tests (S03):** Dry-run reports correct counts; backup created before migration; `KNOWLEDGE.md` entries imported with `source='migrated'`; `agent.db` stage1_outputs imported with `source='extracted'`; skip-on-error for corrupted records.
- **Behavioral regression test (S04):** Playwright or shell test that starts a session, triggers extraction, and asserts `/memory view` output contains entries from `sf.db`.
## Acceptance Criteria
1. `sf.db` `memories` table has `source` column; all `memory-store.js` functions accept/return `source` field.
2. `capture_thought` and `memory_query` are registered native pi tools with TypeBox schemas and are called without errors.
3. Session extraction pipeline writes to `sf.db` with `source='extracted'`; `/memory view` reads from `sf.db`.
4. S03 migration script: dry-run mode reports correct counts; backup created; `agent.db` and `KNOWLEDGE.md` entries imported; old files removed.
5. `grep` finds zero `sql.js` or `better-sqlite3` imports in memory-related code paths.
6. Behavioral regression test passes: `/memory view` output originates from `sf.db`.
## Open Questions
- **`capture_thought`/`memory_query` registration point** — These tools should be registered in `pi-agent-core`'s tool registry or the sf-run bootstrap. The exact registration module needs to be identified before S01 implementation. Current hypothesis: `src/resources/extensions/sf/` bootstrap or a new `memory-tools.js` module. **TBD: investigate `sf-run` tool registration flow.**
- **S04 behavioral test format** — Playwright (requires browser) or shell script (requires `sf` binary)? Shell script with `--print` output parsing is simpler and faster in CI. **Decision needed: test framework for behavioral regression.**

/**
* Phase 3: Property-based tests for FSM correctness using fast-check.
*
* Purpose: Generate arbitrary dispatch sequences and verify FSM invariants:
* 1. Every unit reaches a terminal state (done/failed/blocked)
* 2. State transitions are valid (no illegal combinations)
* 3. Invariants hold under arbitrary input
* 4. No infinite loops or stuck states
*
* Consumer: auto-dispatch FSM uses state transitions; property tests verify
* correctness across all possible paths, not just happy paths.
