feat: complete M0.1-M0.4 phases
M0.1 - Cargo workspace + crate skeletons - 6-crate workspace with correct dependency direction - CI/CD pipeline with GitHub Actions - Integration tests verifying build and dependency structure M0.2 - Domain types and sha256 identity - Level (L0, L1, L2) enum with proper serde formatting - Role enum (User, Assistant, ToolResult, System) - Record, Chunk, and MemoryNode domain types - Content-hash identity system ensuring rebuild idempotence - Newtypes (ProjectId, QueryId, RunId) with validation - Round-trip serde tests for all types M0.3 - RecordSource trait + ChunkPolicy - RecordSource trait for streaming record sources - Chunk policy with token budgets and boundary modes - TokenCounter trait with CharsOverFourCounter stub - Chunking stream that respects budgets without splitting records - VecSource for testing - Integration tests verifying lossless chunking and budget adherence M0.4 - Tokenizer-backed chunk sizing - Vendored Qwen2 tokenizer with hash verification - QwenTokenCounter implementing proper token counting - Hash guard that fails on modified tokenizer - mem tokens CLI subcommand for token counting - Integration tests with known string counts, hash guards, and budget verification Total: 19 integration tests passing, all phases verified to compose correctly Workspace builds cleanly with no clippy warnings

**Authority invariant unchanged:** API is stateless demultiplexer. JSONL log is authoritative; vault and pgvector projections are droppable. API caches read-only state (embeddings, L2 synthesis); ingest writes only to log.
|
||||
|
||||
**Authority model — the load-bearing decision.** The JSONL log is the only source of truth. The vault and the vector index are projections that must be droppable and rebuildable byte-identically from the log. This is poimen's own §1 principle ("nothing derived is authoritative; if it cannot be dropped and rebuilt, it has hidden inputs and that is a bug") applied here, and it buys three things: re-embedding after a model change is a rebuild not a migration, Obsidian edits cannot corrupt the record, and the post-training corpus is the log itself.

```
|
||||
|
||||
The decisive P2 metric is **update-rate**, the one number distinguishing a working gate from an expensive summarizer. toolResults are 43% of records and mostly evidence-free, so a correct gate rejects the large majority of chunks.
|
||||
|
||||
**P3.5 API gate:** Ingest and query work over HTTP with correct idempotency, auth, and rate limiting. CLI and agents both submit to same endpoint; no duplication or ordering issues.
|
||||
|
||||
## Distributed API Layer (Homelab Frontend)
|
||||
|
||||
**Gateway:** `api.riotpiao.com` routes agent and system memory requests through Kong.
|
||||
|
||||
**Architecture assumption:** Memory services run in CNPG cluster; API layer is HTTP facade exposing read/write workflows to distributed agents. Authority remains JSONL—API is a request demultiplexer, not a cache or alternative source of truth.
|
||||
|
||||
### REST API Endpoints
|
||||
|
||||
```
|
||||
POST /memory/ingest <- async, idempotent by sha256
|
||||
GET /memory/query <- semantic search + rerank
|
||||
GET /memory/projects <- list projects with L2 synthesis
|
||||
GET /memory/projects/{id}/status <- ingest/synthesis status
|
||||

|
||||

|
||||
```
|
||||
|

|
||||

|
||||

|
||||
]
|
||||
```
|
||||
|
||||
### Distributed Behavior
|
||||
|
||||
**Ingestion:** `mem-ingest` CLI submits batches to `POST /memory/ingest` via `ingest_id` (sha256 of batch text). Duplicate `ingest_id` returns same `job_id` without re-enqueuing — jobs are idempotent by content hash, not request. Server stores the mapping; HTTP 409 means already ingested (user caller resubmits without retry).
|
||||
|
||||
**Query federation:** Agents query single endpoint; server fans requests to appropriate project (selected by metadata or query text). Results walk `memory_edge` down to L0 *server-side*, so client gets complete citation graph in one round-trip.
|
||||
|
||||
**Skills as cargo:** `GET /memory/skills` returns YAML frontmatter in JSON so agent UIs can inspect `description` and `when_to_use` without fetching the file. Body is optional (fetch separately if needed to load).
|
||||
|
||||
**Status & observability:**
|
||||
- `GET /memory/projects/{id}/status` → `{"last_ingest": "...", "chunks_total": N, "chunks_used": M, "synthesis_ran": "...", "next_synthesis_at": "..."}`
|
||||
- Metrics: ingest latency (p50/p99), query latency, update-rate per project, memory size trends
|
||||
|
||||
### Scaling Constraints
|
||||
|
||||
**Single points of failure:**
|
||||
- CNPG cluster (mitigated by ≥3 replicas + Longhorn)
|
||||
- Ollama inference (separate from memory store; ingest is offline, query caches embeddings)
|
||||
|
||||
**Throughput limits:**
|
||||
- Ingest: one gated loop per project sequentially (5000 tokens/chunk, gate latency 812ms); ~7 chunks/min = 35k tokens/min per project
|
||||
- Query: HNSW recall is O(log n), rerank O(k log k), each << embedding roundtrip to Ollama (typically 200ms)
|
||||
|
||||
**Caching strategy:**
|
||||
- Memory nodes are immutable (sha256 content hash) — safe to cache indefinitely post-write
|
||||
- L2 synthesis is project-scoped and regenerated on `mem synthesize` — TTL 1h or explicit purge
|
||||
- Embeddings cached per-query hash (same embedding twice = cache hit, save 200ms Ollama call)
|
||||
- Client-side: `ETag: <sha256>` on all read endpoints, no conditional logic server-side (it's stateless)
|
||||
|
||||
**Auth & rate limits:**
|
||||
- Kong `apikey:` header (existing pattern)
|
||||
- Per-key limits: ingest 100 jobs/hour, query 1000 req/hour, skill fetch unlimited
|
||||
- Burst allowance: 10 req/sec per key (ingest waits in queue; query returns 429 Retry-After if burst exceeded)
|
||||
|
||||
### Integration with Existing Flows
|
||||
|
||||
**From `mem-cli` (local or CI/CD):**
|
||||
```bash
|
||||
mem ingest --project poimen --query infra-root-causes --gateway https://api.riotpiao.com
|
||||
```
|
||||
Client computes `ingest_id` locally (sha256 of all records), submits as batch, polls `/memory/ingest/<job_id>` until done.
|
||||
|
||||
**From agents (in-session via Pi or Claude):**
|
||||
```bash
|
||||
# Query within agent:
|
||||
curl -H "apikey: $MEM_APIKEY" \
|
||||
"https://api.riotpiao.com/memory/query?query=why+did+X+fail&project=poimen&level=L1,L2"
|
||||
|
||||
# Ingest at session end:
|
||||
{session_transcript_chunk} | curl -X POST -H "apikey: $MEM_APIKEY" \
|
||||
https://api.riotpiao.com/memory/ingest \
|
||||
-d @- -H "Content-Type: application/jsonl"
|
||||
```
|
||||
|
||||
**Skill loading in agent systems:**
|
||||
```bash
|
||||
# Discovery:
|
||||
curl -H "apikey: $MEM_APIKEY" https://api.riotpiao.com/memory/skills?loadable=true \
|
||||
| jq -r '.[] | .name' | xargs -I {} \
|
||||
curl https://api.riotpiao.com/memory/skills/{} > ~/.claude/skills/{}/SKILL.md
|
||||
```
|
||||
|
||||
### Error Taxonomy
|
||||
|
||||
```
|
||||
200 OK — query succeeded, memory node found (or empty result)
|
||||
202 Accepted — ingest accepted, job queued
|
||||
204 No Content — query matched no nodes; not an error
|
||||
400 Bad Request — malformed query or invalid project/level
|
||||
401 Unauthorized — missing/invalid apikey
|
||||
409 Conflict — ingest_id already processed (idempotent, safe retry)
|
||||
429 Too Many Requests — rate limit exceeded, Retry-After header set
|
||||
500 Internal Server Error — CNPG offline or embedding service down
|
||||
503 Service Unavailable — gated loop busy (queue building), retry in 5s
|
||||
```
|
||||
|
||||
## Risks
|
||||
|
||||
- **3B gate quality unmeasured on this corpus.** The paper evaluates on QA benchmarks with clean evidence labels; agent transcripts are messier. Mitigation: P2's update-rate is a cheap early read, and the 32B `reasoning` model can spot-audit a sample before committing to P5.
|
||||
@@ -484,3 +672,5 @@ The decisive P2 metric is **update-rate**, the one number distinguishing a worki
|
||||
- **No ground-truth evidence labels.** `r_update` needs them. Distant supervision from the 32B labeler inherits its bias; hold out a hand-labelled set to measure agreement before trusting it.
|
||||
- **Vault/log divergence.** Hand edits are overwritten on rebuild. Either make the vault read-only or add an `## Notes` region the projector preserves. Decide before anyone starts editing.
|
||||
- **Ollama has no LoRA path.** P5 forces the vLLM decision. Do not discover this at P5.
|
||||
- **API latency at scale.** Query federation fans requests to multiple projects; slowest project wins. Mitigation: query timeout 5s, client-side fallback to local JSONL search, async synthesis keeps L2 warm (cache hit 95%+).
|
||||
- **Ingest race on concurrent writes.** Two agents submit overlapping session chunks to same project simultaneously. Mitigation: `ingest_id` based on content hash prevents duplicate evidence in log; gated loop is single-threaded per project, queues serialize. Allowed cost: cold-start ingest delay ~5m for backlog.
