Copy `applyMemoryEnv()` and `bootstrapMemory()` from `packages/memory/src/` +2. Convert to arrow functions per project style +3. Re-export from `src/index.ts` as `bootstrapMemory`, `applyMemoryEnv` +4. Update `packages/agents/package.json`: replace `@openzosma/memory` with `@openzosma/zosma-mem` +5.

Copy the 4 source files verbatim, convert `function` to arrow syntax, update imports, delete the old package. + +--- + +### Phase 1 — Types + Salience Engine + +**Files:** `src/types.ts`, `src/config.ts`, `src/engine/salience.ts` + +1. Define core types from the paper: + - `MemoryScore` — `{ reuseCount, decisionInfluence, ignoredReads, lastAccessed, attentionWeight }` + - `MemoryEntity` — `{ id, source: { branch, commitRef }, score, tags, content }` + - `MemoryEvent` (engine-internal, distinct from eval `MemoryEvent`) — `{ id, type, context, attentionWeight?, metadata?, timestamp }` + - `MemoryConfig` — `{ memoryDir, salienceThreshold?, gcIntervalMs?, summarizer? }` + - `Summarizer` — `(texts: string[]) => Promise` + - `AttentionQuery` — `{ taskDescription, activeToolName?, intent? }` + - `ScoredEntity` — `{ entity, attentionScore }` + - `GcReport` — `{ decayed, pruned, consolidated }` + +2. Implement `computeSalience(score: MemoryScore): number`: + ``` + S(e) = 2*reuseCount + 5*decisionInfluence - 2*ignoredReads - ln(1 + ageDays) + ``` + +3. Implement `meetsThreshold(salience: number, threshold: number): boolean` + +**Tests:** `src/engine/__tests__/salience.test.ts` +- Fresh entity → salience = 0 (passes threshold 0, fails threshold 0.4) +- Decision entity → salience = 5 (high) +- Heavily ignored entity → negative salience +- Time decay: 30 days → ~3.4 decay + +**Agent instructions:** Pure functions, no I/O. Use the exact formula from the paper. `ageDays = (Date.now() - lastAccessed) / 86_400_000` — but accept a `now` parameter for testability. + +--- + +### Phase 2 — Brain Adapter + +**Files:** `src/brain-adapter/parser.ts`, `src/brain-adapter/state.ts` + +1. `parseCommits(markdown: string): ParsedCommit[]` — parse `commits.md` using `unified` + `remark-parse` into structured commit objects (heading, body, ref) +2. `readState(memoryDir: string): MemoryState` — parse `state.yaml` via `yaml` package +3. `listBranches(memoryDir: string): string[]` — read `.memory/branches/` directory + +**Dependencies to add:** `unified`, `remark-parse`, `yaml` + +**Tests:** `src/brain-adapter/__tests__/parser.test.ts` — parse sample commits.md fixtures + +**Agent instructions:** Use `unified().use(remarkParse).parse(markdown)` to get an MDAST. Walk heading nodes to extract commit boundaries. Do NOT use regex. + +--- + +### Phase 3 — Entity Store + +**Files:** `src/store/entity-store.ts`, `src/store/co-access.ts` + +1. `EntityStore` class: + - `read(entityId: string): MemoryEntity | undefined` — read `.salience/.yaml` + - `write(entity: MemoryEntity): void` — write `.salience/.yaml` + - `list(): string[]` — list all entity IDs + - `archive(entityId: string): void` — move to `.salience/archive/` + - `ensureDir(): void` — create `.salience/` and `.salience/archive/` if needed + +2. `CoAccessGraph` class: + - `load(memoryDir: string): Record` + - `save(memoryDir: string, graph: Record): void` + - `recordCoAccess(graph, entityIds: string[]): void` — update bidirectional edges + +**Dependencies to add:** `yaml` (already from phase 2) + +**Tests:** `src/store/__tests__/entity-store.test.ts` — write/read/list/archive round-trip in temp dir + +**Agent instructions:** Use synchronous `fs` for reads (small YAML files). Async for writes. YAML format must match the paper's schema exactly. + +--- + +### Phase 4 — Ingestion + Commit Indexer + +**Files:** `src/ingestion/event-bus.ts`, `src/ingestion/ingest.ts`, `src/ingestion/commit-indexer.ts` + +1. `EventBus` — typed `EventEmitter` for `MemoryEvent` lifecycle (ingested, discarded, scored) +2. `ingest(event: MemoryEvent, store: EntityStore, config: MemoryConfig): boolean` — compute salience, persist if above threshold, return true/false +3. `CommitIndexer`: + - Parse commits.md via brain adapter + - Track processed commit refs (stored in `.salience/.indexed` file) + - Extract entities from each unprocessed commit + - Call `ingest()` for each + - `reindex()` — idempotent full re-index + +**Dependencies to add:** `chokidar` (for watch mode — optional, can defer) + +**Tests:** `src/ingestion/__tests__/ingest.test.ts` — event above threshold persists, below threshold discards + +**Agent instructions:** CommitIndexer.reindex() must be idempotent. Store processed refs as a JSON array in `.salience/.indexed`. The cold-start case (no .indexed file) processes all commits. + +--- + +### Phase 5 — Attention-Gated Retrieval + +**Files:** `src/retrieval/retrieve.ts` + +1. `retrieve(query: AttentionQuery, store: EntityStore, coAccess: CoAccessGraph, topK: number): ScoredEntity[]` +2. Attention score: `A(q, e) = 3*tagOverlap(q, e) + S(e) + coAccessBoost(e)` + - `tagOverlap` = count of entity tags appearing in `query.taskDescription` (case-insensitive) + - `coAccessBoost` = +1 if any co-accessed entity is also in the current result set (two-pass) +3. Sort by attention score descending, return top-K +4. After retrieval, update co-access graph for the returned entity set + +**Tests:** `src/retrieval/__tests__/retrieve.test.ts` +- High tag overlap beats high salience with no overlap +- Co-access boost surfaces related entities + +**Agent instructions:** Two-pass retrieval: first pass computes base scores (tag overlap + salience), take top 2K candidates. Second pass adds co-access boost among candidates, re-sort, return top-K. + +--- + +### Phase 6 — Reinforcement + +**Files:** `src/engine/reinforcement.ts` + +1. `recordRead(entityId, store)` → `reuseCount += 1`, update `lastAccessed` +2. `recordIgnoredRead(entityId, store)` → `ignoredReads += 1` +3. `recordDecisionInfluence(entityId, store)` → `decisionInfluence += 1`, update `lastAccessed` + +**Tests:** `src/engine/__tests__/reinforcement.test.ts` — counters increment, lastAccessed updates + +**Agent instructions:** Each function reads the entity, mutates the score, writes back. Simple read-modify-write. No locking needed (single-process). + +--- + +### Phase 7 — Engine Factory + +**Files:** `src/engine/factory.ts` + +1. `createMemoryEngine(config: MemoryConfig): MemoryEngine` + - Instantiate `EntityStore`, `CoAccessGraph`, `CommitIndexer` + - Wire `ingest`, `retrieve`, `recordRead`, `recordIgnoredRead`, `recordDecisionInfluence`, `reindex`, `gc`, `shutdown` + - Start GC interval timer + - Return the `MemoryEngine` interface + +**Tests:** `src/engine/__tests__/factory.test.ts` — create engine, ingest event, retrieve it, shutdown + +**Agent instructions:** The engine is the composition root. It owns the lifecycle of the GC timer. `shutdown()` clears the timer. All methods delegate to the subsystem modules. + +--- + +### Phase 8 — Garbage Collection + +**Files:** `src/gc/decay.ts`, `src/gc/prune.ts`, `src/gc/consolidate.ts` + +1. `decay(store: EntityStore, now: number)` — recompute salience for all entities, write updated scores +2. `prune(store: EntityStore, threshold: number)` — archive entities below threshold for N consecutive cycles (track cycle count in `.salience/.yaml` as `belowThresholdCycles`) +3. `consolidate(store, coAccess, summarizer?)` — find clusters of co-accessed entities all below threshold, merge into single summary entity + +**Tests:** `src/gc/__tests__/gc.test.ts` +- Decay reduces salience of old entities +- Prune archives after N cycles +- Consolidate merges cluster into one entity + +**Agent instructions:** Prune should NOT archive on the first cycle below threshold. Default: archive after 3 consecutive cycles below threshold (configurable). If no summarizer provided, consolidate concatenates content with `\n---\n` separators and truncates to 2000 chars. + +--- + +### Phase 9 — Self-Adapter for Evals + +**Files:** `src/adapter/self-adapter.ts` + +1. Implement `MemoryAdapter` (from `src/evals/types.ts`) wrapping `createMemoryEngine()` +2. Map between eval types and engine types: + - `MemoryEvent` (eval) → `MemoryEvent` (engine) + - `RetrieveQuery` → `AttentionQuery` + - `RetrievedEntity` ← `ScoredEntity` + - `UsageSignal` → `recordRead` / `recordIgnoredRead` / `recordDecisionInfluence` + - `GcResult` ← `GcReport` +3. `setup()` creates engine with `opts.workDir` as memoryDir, injects deterministic clock +4. `teardown()` calls `engine.shutdown()` + +**Tests:** Run the existing 7 eval scenarios against the self-adapter: +```bash +pnpm --filter zosma-mem run eval +``` + +**Agent instructions:** The self-adapter is the bridge that proves the engine works. All 7 scenarios must pass. The deterministic clock must be injected into the salience engine's `now` parameter — do NOT use `Date.now()` in any engine code; always accept a clock/now parameter. + +--- + +### Phase 10 — Integration + Cleanup + +1. Update `packages/zosma-mem/package.json`: + - Rename to `@openzosma/zosma-mem` + - Add dependencies: `yaml`, `unified`, `remark-parse`, `pino`, `p-limit`, `chokidar` + - Add bootstrap exports: `"./bootstrap"` export path + - Keep `"./evals"` export path + +2. Update `packages/agents/package.json`: + - Replace `"@openzosma/memory": "workspace:*"` with `"@openzosma/zosma-mem": "workspace:*"` + +3. Update `packages/agents/src/pi.agent.ts`: + - `import { bootstrapMemory } from "@openzosma/zosma-mem/bootstrap"` + +4. Update `packages/gateway/src/session-manager.ts` (if it references `@openzosma/memory`) + +5. Delete `packages/memory/` + +6.

Memory Classification - -The system implements four categories of memory, each managed by different components: - -### Long-term memory (MEMORY.md) - -**Owner:** pi-memory -**File:** `.pi/agent/memory/MEMORY.md` -**Lifecycle:** Persists across sessions via PV. Never automatically pruned. -**Purpose:** Durable facts, decisions, preferences, and constraints. - -```markdown - -#decision [[database-choice]] Chose PostgreSQL for all backend services. No ORM. - - -#preference [[editor]] User prefers Neovim with LazyVim config. -``` - -Written explicitly by the agent via the `memory_write` tool when it identifies something -worth remembering. Uses `#tags` and `[[wikilinks]]` for retrieval. - -### Episodic memory (daily logs) - -**Owner:** pi-memory -**File:** `.pi/agent/memory/daily/YYYY-MM-DD.md` -**Lifecycle:** One file per calendar day. Persists across sessions. Never pruned. -**Purpose:** Running narrative of what happened during work. Captures context flow. - -Written to in three ways: -1. Agent calls `memory_write` with `target: "daily"` during execution -2. **Session handoff** — pi-memory auto-captures open scratchpad items + recent daily log - context to the daily file before each compaction (`session_before_compact` hook) -3. **Exit summary** — pi-memory generates an LLM summary of the session and appends it - to the daily file on `session_shutdown` - -Today's and yesterday's daily logs are loaded into context at every turn. - -### Working memory (scratchpad) - -**Owner:** pi-memory -**File:** `.pi/agent/memory/SCRATCHPAD.md` -**Lifecycle:** Persists across sessions.

What This System Does Not Do +## Non-Goals -- **No database storage for memory.** Memory is files on disk, not rows in PostgreSQL. -- **No cross-session real-time sharing.** Each pod reads its own PV. There is no pub/sub - for memory updates between concurrent sessions. -- **No automatic pruning of long-term memory.** MEMORY.md grows unbounded. Manual curation - by the agent (or user) is the only mechanism. -- **No embedding generation.** Embeddings are handled by qmd externally, not by this system. -- **No memory deduplication across files.** The same fact could exist in MEMORY.md and a - daily log. Search results may contain duplicates. -- **No access control on memory.** Any agent with PV access can read/write all memory files. -- **No encryption at rest.** Memory files are plaintext markdown. -- **No memory versioning or rollback.** Files are append-only with no git-like history. +- No database storage. Memory stays file-based. +- No cross-session real-time sync. Each session reads its own files. +- No embedding model. Retrieval uses tag-based attention scoring. +- No changes to gateway/session-manager (memoryDir wiring works). +- No removal of zosma-mem engine.

Copy the 4 source files verbatim, convert `function` to arrow syntax, update imports, delete the old package. - ---- - -### Phase 1 — Types + Salience Engine - -**Files:** `src/types.ts`, `src/config.ts`, `src/engine/salience.ts` - -1. Define core types from the paper: - - `MemoryScore` — `{ reuseCount, decisionInfluence, ignoredReads, lastAccessed, attentionWeight }` - - `MemoryEntity` — `{ id, source: { branch, commitRef }, score, tags, content }` - - `MemoryEvent` (engine-internal, distinct from eval `MemoryEvent`) — `{ id, type, context, attentionWeight?, metadata?, timestamp }` - - `MemoryConfig` — `{ memoryDir, salienceThreshold?, gcIntervalMs?, summarizer? }` - - `Summarizer` — `(texts: string[]) => Promise` - - `AttentionQuery` — `{ taskDescription, activeToolName?, intent? }` - - `ScoredEntity` — `{ entity, attentionScore }` - - `GcReport` — `{ decayed, pruned, consolidated }` - -2. Implement `computeSalience(score: MemoryScore): number`: - ``` - S(e) = 2*reuseCount + 5*decisionInfluence - 2*ignoredReads - ln(1 + ageDays) - ``` - -3. Implement `meetsThreshold(salience: number, threshold: number): boolean` - -**Tests:** `src/engine/__tests__/salience.test.ts` -- Fresh entity → salience = 0 (passes threshold 0, fails threshold 0.4) -- Decision entity → salience = 5 (high) -- Heavily ignored entity → negative salience -- Time decay: 30 days → ~3.4 decay - -**Agent instructions:** Pure functions, no I/O. Use the exact formula from the paper. `ageDays = (Date.now() - lastAccessed) / 86_400_000` — but accept a `now` parameter for testability. - ---- - -### Phase 2 — Brain Adapter - -**Files:** `src/brain-adapter/parser.ts`, `src/brain-adapter/state.ts` - -1. `parseCommits(markdown: string): ParsedCommit[]` — parse `commits.md` using `unified` + `remark-parse` into structured commit objects (heading, body, ref) -2. `readState(memoryDir: string): MemoryState` — parse `state.yaml` via `yaml` package -3. `listBranches(memoryDir: string): string[]` — read `.memory/branches/` directory - -**Dependencies to add:** `unified`, `remark-parse`, `yaml` - -**Tests:** `src/brain-adapter/__tests__/parser.test.ts` — parse sample commits.md fixtures - -**Agent instructions:** Use `unified().use(remarkParse).parse(markdown)` to get an MDAST. Walk heading nodes to extract commit boundaries. Do NOT use regex. - ---- - -### Phase 3 — Entity Store - -**Files:** `src/store/entity-store.ts`, `src/store/co-access.ts` - -1. `EntityStore` class: - - `read(entityId: string): MemoryEntity | undefined` — read `.salience/.yaml` - - `write(entity: MemoryEntity): void` — write `.salience/.yaml` - - `list(): string[]` — list all entity IDs - - `archive(entityId: string): void` — move to `.salience/archive/` - - `ensureDir(): void` — create `.salience/` and `.salience/archive/` if needed - -2. `CoAccessGraph` class: - - `load(memoryDir: string): Record` - - `save(memoryDir: string, graph: Record): void` - - `recordCoAccess(graph, entityIds: string[]): void` — update bidirectional edges - -**Dependencies to add:** `yaml` (already from phase 2) - -**Tests:** `src/store/__tests__/entity-store.test.ts` — write/read/list/archive round-trip in temp dir - -**Agent instructions:** Use synchronous `fs` for reads (small YAML files). Async for writes. YAML format must match the paper's schema exactly. - ---- - -### Phase 4 — Ingestion + Commit Indexer - -**Files:** `src/ingestion/event-bus.ts`, `src/ingestion/ingest.ts`, `src/ingestion/commit-indexer.ts` - -1. `EventBus` — typed `EventEmitter` for `MemoryEvent` lifecycle (ingested, discarded, scored) -2. `ingest(event: MemoryEvent, store: EntityStore, config: MemoryConfig): boolean` — compute salience, persist if above threshold, return true/false -3. `CommitIndexer`: - - Parse commits.md via brain adapter - - Track processed commit refs (stored in `.salience/.indexed` file) - - Extract entities from each unprocessed commit - - Call `ingest()` for each - - `reindex()` — idempotent full re-index - -**Dependencies to add:** `chokidar` (for watch mode — optional, can defer) - -**Tests:** `src/ingestion/__tests__/ingest.test.ts` — event above threshold persists, below threshold discards - -**Agent instructions:** CommitIndexer.reindex() must be idempotent. Store processed refs as a JSON array in `.salience/.indexed`. The cold-start case (no .indexed file) processes all commits. - ---- - -### Phase 5 — Attention-Gated Retrieval - -**Files:** `src/retrieval/retrieve.ts` - -1. `retrieve(query: AttentionQuery, store: EntityStore, coAccess: CoAccessGraph, topK: number): ScoredEntity[]` -2. Attention score: `A(q, e) = 3*tagOverlap(q, e) + S(e) + coAccessBoost(e)` - - `tagOverlap` = count of entity tags appearing in `query.taskDescription` (case-insensitive) - - `coAccessBoost` = +1 if any co-accessed entity is also in the current result set (two-pass) -3. Sort by attention score descending, return top-K -4. After retrieval, update co-access graph for the returned entity set - -**Tests:** `src/retrieval/__tests__/retrieve.test.ts` -- High tag overlap beats high salience with no overlap -- Co-access boost surfaces related entities - -**Agent instructions:** Two-pass retrieval: first pass computes base scores (tag overlap + salience), take top 2K candidates. Second pass adds co-access boost among candidates, re-sort, return top-K. - ---- - -### Phase 6 — Reinforcement - -**Files:** `src/engine/reinforcement.ts` - -1. `recordRead(entityId, store)` → `reuseCount += 1`, update `lastAccessed` -2. `recordIgnoredRead(entityId, store)` → `ignoredReads += 1` -3. `recordDecisionInfluence(entityId, store)` → `decisionInfluence += 1`, update `lastAccessed` - -**Tests:** `src/engine/__tests__/reinforcement.test.ts` — counters increment, lastAccessed updates - -**Agent instructions:** Each function reads the entity, mutates the score, writes back. Simple read-modify-write. No locking needed (single-process). - ---- - -### Phase 7 — Engine Factory - -**Files:** `src/engine/factory.ts` - -1. `createMemoryEngine(config: MemoryConfig): MemoryEngine` - - Instantiate `EntityStore`, `CoAccessGraph`, `CommitIndexer` - - Wire `ingest`, `retrieve`, `recordRead`, `recordIgnoredRead`, `recordDecisionInfluence`, `reindex`, `gc`, `shutdown` - - Start GC interval timer - - Return the `MemoryEngine` interface - -**Tests:** `src/engine/__tests__/factory.test.ts` — create engine, ingest event, retrieve it, shutdown - -**Agent instructions:** The engine is the composition root. It owns the lifecycle of the GC timer. `shutdown()` clears the timer. All methods delegate to the subsystem modules. - ---- - -### Phase 8 — Garbage Collection - -**Files:** `src/gc/decay.ts`, `src/gc/prune.ts`, `src/gc/consolidate.ts` - -1. `decay(store: EntityStore, now: number)` — recompute salience for all entities, write updated scores -2. `prune(store: EntityStore, threshold: number)` — archive entities below threshold for N consecutive cycles (track cycle count in `.salience/.yaml` as `belowThresholdCycles`) -3. `consolidate(store, coAccess, summarizer?)` — find clusters of co-accessed entities all below threshold, merge into single summary entity - -**Tests:** `src/gc/__tests__/gc.test.ts` -- Decay reduces salience of old entities -- Prune archives after N cycles -- Consolidate merges cluster into one entity - -**Agent instructions:** Prune should NOT archive on the first cycle below threshold. Default: archive after 3 consecutive cycles below threshold (configurable). If no summarizer provided, consolidate concatenates content with `\n---\n` separators and truncates to 2000 chars. - ---- - -### Phase 9 — Self-Adapter for Evals - -**Files:** `src/adapter/self-adapter.ts` - -1. Implement `MemoryAdapter` (from `src/evals/types.ts`) wrapping `createMemoryEngine()` -2. Map between eval types and engine types: - - `MemoryEvent` (eval) → `MemoryEvent` (engine) - - `RetrieveQuery` → `AttentionQuery` - - `RetrievedEntity` ← `ScoredEntity` - - `UsageSignal` → `recordRead` / `recordIgnoredRead` / `recordDecisionInfluence` - - `GcResult` ← `GcReport` -3. `setup()` creates engine with `opts.workDir` as memoryDir, injects deterministic clock -4. `teardown()` calls `engine.shutdown()` - -**Tests:** Run the existing 7 eval scenarios against the self-adapter: -```bash -pnpm --filter zosma-mem run eval -``` - -**Agent instructions:** The self-adapter is the bridge that proves the engine works. All 7 scenarios must pass. The deterministic clock must be injected into the salience engine's `now` parameter — do NOT use `Date.now()` in any engine code; always accept a clock/now parameter. - ---- - -### Phase 10 — Integration + Cleanup - -1. Update `packages/zosma-mem/package.json`: - - Rename to `@openzosma/zosma-mem` - - Add dependencies: `yaml`, `unified`, `remark-parse`, `pino`, `p-limit`, `chokidar` - - Add bootstrap exports: `"./bootstrap"` export path - - Keep `"./evals"` export path - -2. Update `packages/agents/package.json`: - - Replace `"@openzosma/memory": "workspace:*"` with `"@openzosma/zosma-mem": "workspace:*"` - -3. Update `packages/agents/src/pi.agent.ts`: - - `import { bootstrapMemory } from "@openzosma/zosma-mem/bootstrap"` - -4.
