The recurrence is the algorithm applied to its own output, so `mem-core` implements one loop and the level is a parameter. Two consequences worth having on purpose: - -- **Exit gate flips by level.** Off at L1 (see below), reasonably *on* at L2, where the input is a handful of memories rather than hundreds of chunks and "enough evidence" is actually decidable. -- **Levels form a provenance graph, not a pile.** Each L1 node records the L0 nodes that produced it; each L2 node records its L1 parents. That graph *is* the Obsidian link structure and the `parent_id` edges in Postgres — one relationship expressed in both projections. - -## Architecture - -``` - api.riotpiao.com (nginx ingress + homelab-frontend gateway) - │ - ┌─────────────────┼─────────────────┐ - │ │ │ - /ingest /query /skills - (async) (sync) (read-only) - │ │ │ - ▼ ▼ ▼ - ┌─────────────────────────────────────────────────────┐ - │ API Server (Rust httpd) mem-store / mem-llm │ - │ - ingest_id dedup + queue │ - │ - query → HNSW + rerank + edge-walk │ - │ - skill catalog (excludes _drafts) │ - └──────────────────┬──────────────────────────────────┘ - │ - pi/claude CLI ─────┼────── agents in-session - local or CI/CD │ (embedded queries) - │ - ┌──────────────────┴──────────────────┐ - │ │ - ▼ ▼ - [ Ingest Queue ] [ CNPG Cluster ] - (redis or local) (pgvector, HNSW) - │ │ - ├─────────────────────────────────────┤ - │ - ▼ -pi sessions / claude transcripts / loop.sh artifacts - │ - ▼ project resolver (cwd -> project id) - [ Chunk Parser ] 5000-token chunks, split on message boundaries - │ - ▼ -┌──────────────────────────────────────────────────────┐ -│ GRU-Mem Controller qwen2.5:3b-instruct │ -│ reason about chunk vs question │ -│ yes|no -> update gate U_t │ -│ candidate memory M̂_t │ -│ continue|end -> exit gate E_t │ -└───────────────┬──────────────────────────────────────┘ - U_t=yes │ U_t=no - ┌───────┴────────┐ - ▼ ▼ - emit L0 evidence discard chunk - M_t <- M̂_t M_t <- M_{t-1} - │ - ▼ L1 memory per standing query - └──────► same loop, input = L1 memories ──► L2 project synthesis - │ - ▼ -┌──────────────────────────────────────────────────────┐ -│ JSONL event log AUTHORITATIVE │ -│ Obsidian vault derived projection │ -│ pgvector index derived projection │ -└──────────────────────────────────────────────────────┘ -``` - -**Authority invariant unchanged:** API is stateless demultiplexer.

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. - -## Standing queries - -The paper's memory agent is `φθ(Q, C_t, M_{t-1})` — **it requires a question**. The update gate is defined as "does this chunk contain useful information *about the problem*". Without `Q` the gate has no referent, and `r_update` becomes undefinable, which forecloses post-training. - -So each project declares durable questions in YAML.

L1 extraction is exactly that shape. Keep the gate *recorded* (its signal is needed for RL) but do not act on it. Enable at L2 and for interactive retrieval, where the paper measures 4× speedup. - -## Separate weights — yes, specifically a LoRA adapter - -Confirming the instinct, with the reason that actually matters here: - -- **Base:** Qwen2.5-3B-Instruct, already resident as `qwen2.5:3b-instruct` -- **Memory policy:** LoRA adapter, rank 16–32, ~30–60 MB - -Why an adapter rather than a fine-tuned model: - -1. **VRAM.** One GPU, `OLLAMA_MAX_LOADED_MODELS=2`, currently holding `ornith:35b` + `qwen2.5:3b`. A separate full memory model evicts something, and eviction here is a weights reload measured in tens of seconds — we already watched `ornith` cold-start blow a 60s gateway timeout. A LoRA rides on the resident base for near-zero extra VRAM. -2. **Iteration.** Post-training emits a ~50 MB adapter, not a 6 GB model. Swap without redeploying. -3. **Reversibility.** A gate-behaviour regression reverts by pointing at the previous adapter. - -**Infra consequence to accept up front:** Ollama cannot hot-swap LoRA adapters. Serving one means either moving the memory model to a **vLLM** InferenceService with `--enable-lora` (the `reasoning` predictor is already vLLM v0.11.0, so the pattern exists), or merging into a GGUF for Ollama and losing swappability.

At L1 over a finite transcript it is switched off because "read everything" is well defined (paper §3.3). Over a live stream there is no everything, so the gate stops being an optimisation and becomes the only termination condition — which is an argument for keeping it trained even while it is switched off. - -## Storage schemas - -### JSONL event log — authoritative - -`log///.jsonl`. **Every record carries `level`.** - -```jsonl -{"type":"run","level":"L1","project":"poimen","query_id":"infra-root-causes","input_level":"chunk","model":"qwen2.5:3b-instruct","chunk_tokens":5000,"memory_budget":1024,"exit_gate":false,"ts":"..."} -{"type":"chunk","level":"L0","t":1,"source":"pi:2026-07-21T16-23-59_019f857d","span":[0,42],"sha256":"..."} -{"type":"gate","level":"L1","t":1,"update":false,"exit":false,"think":"...","latency_ms":812} -{"type":"evidence","level":"L0","t":7,"source":"pi:...","text":"...","sha256":"..."} -{"type":"memory","level":"L1","t":7,"text":"...","tokens":142,"parents":[""],"sha256":"..."} -{"type":"run_end","level":"L1","chunks_seen":412,"chunks_used":17,"final_memory_sha":"..."} -``` - -The L2 pass writes the same record types with `"level":"L2"`, `"input_level":"L1"`, and `parents` holding L1 shas. `evidence` records appear only when the update gate opened, so update-rate is directly measurable and memory at any `t` is replayable. - -### pgvector — projection - -One table across all levels, because retrieval wants to search them together and filter: - -```sql -CREATE TABLE memory_node ( - id BIGSERIAL PRIMARY KEY, - level TEXT NOT NULL CHECK (level IN ('L0','L1','L2','R')), - project TEXT NOT NULL, - query_id TEXT, -- null at L2 and R - run_id TEXT NOT NULL, - t INT NOT NULL, - source TEXT, -- set at L0; source URI at R - text TEXT NOT NULL, - sha256 TEXT NOT NULL UNIQUE, - created_at TIMESTAMPTZ NOT NULL DEFAULT now() -); -CREATE TABLE memory_edge ( -- provenance: child <- parent - child_sha TEXT NOT NULL REFERENCES memory_node(sha256), - parent_sha TEXT NOT NULL REFERENCES memory_node(sha256), - PRIMARY KEY (child_sha, parent_sha) - -- No row may point at an R node as parent.

The flag exists for when the graph view is worth the file count. - -## Skills — the procedural projection - -**A skill is a projection, not a level.** L0/L1/L2 are all *descriptive* — what happened. A skill is *procedural* — what to do next time. That is a change of modality, not a further compression, so the gated loop does not produce it: the update gate's question ("does this chunk contain evidence for Q") has no meaning when the output is an instruction. - -The format is free. `SKILL.md` is YAML frontmatter plus markdown, which is exactly an Obsidian note — verified against `~/.claude/skills/seo-geo-claude-skills/research/keyword-research/SKILL.md`, whose frontmatter carries `name`, `description`, `when_to_use`, `argument-hint`. So `vault/skills//SKILL.md` is simultaneously a vault note and a loadable skill, with no conversion step: - -```sh -pi --skill vault/skills/ # or set skillsPath in ~/.pi/config.json -ln -s .../vault/skills/ ~/.claude/skills/ -``` - -`mem skill draft --from poimen/infra-root-causes` reads an L1 or L2 note and writes a draft. Emission should follow the existing authoring rubric rather than inventing one — the installed `grafana-core:skill-authoring` skill encodes Anthropic's Agent Skills guidance and a four-dimension rubric (conciseness, actionability, workflow clarity, progressive disclosure). Description quality is the whole game: a skill whose `description` does not match how the user actually phrases the request never fires. - -**Drafts are never auto-loaded, and promotion is manual.** This is the one place the system can close a loop on itself, and the failure is subtle: - -> a memory-derived skill is auto-loaded → it appears in future session transcripts → those transcripts are ingested as evidence → the memory that produced the skill is reinforced by its own output - -No external verifier breaks that cycle. It is the same hazard poimen §16 names when it gates "automatic workflow mutation without human approval" by default, and it is why `_drafts/` is a separate directory rather than a frontmatter flag — a directory cannot be accidentally globbed into `--skill`. - -Two mechanical guards: - -1. **Promotion is a human move** out of `_drafts/`, reviewable as a diff. -2. **Provenance marks derived text.** Every emitted skill carries `generated_from: ` in frontmatter, and `mem-ingest` tags chunks matching a known emitted artifact as `derived: true` and excludes them from evidence. Without this the corpus slowly becomes its own training data. - -## Source connectors — extensible multi-source ingestion - -Memory service is a **cluster-wide RAG** serving multiple agents and workflows. Knowledge does not live in one place — it is spread across an Obsidian vault, a paperless-ngx instance, agent session logs, and whatever document stores appear next. The connector architecture makes adding a new source a single-trait implementation rather than a pipeline rewrite. - -### The problem with hardcoded sources - -Today `mem-ingest` has three concrete sources: `PiSessionSource`, `ClaudeTranscriptSource`, `DocCorpusSource`. Each knows its own file format and emits `Record`s through the `RecordSource` trait. This works, but: - -1. **Every new source requires Rust code.** paperless-ngx has a REST API; Confluence has another; S3 is a third protocol. Each lands as a new `.rs` file compiled into the binary. -2. **No runtime discovery.** The CLI must know about every source at compile time. A homelab that adds Bookstack next month needs a code change, a rebuild, and a redeploy. -3. **No shared sync logic.** Change detection (sha-based skip), tombstoning, drift reporting — each source will reimplement these unless the framework provides them. - -### Design: `SourceConnector` trait + registry - -A connector is anything that can enumerate documents and yield their content. The framework handles chunking, embedding, change detection, and storage. - -```rust -/// A connector to an external document source. -#[async_trait] -pub trait SourceConnector: Send + Sync { - /// Unique connector kind identifier (e.g., "obsidian", "paperless", "s3") - fn kind(&self) -> &str; - - /// Human-readable name for this connector instance - fn name(&self) -> &str; - - /// Enumerate all documents available from this source. - /// Returns (doc_id, doc_metadata) pairs. - async fn list_documents(&self) -> Result>; - - /// Fetch content for a single document by its source-specific ID. - async fn fetch_document(&self, doc_id: &str) -> Result; - - /// Health check — can we reach this source? - async fn health_check(&self) -> Result; -} - -/// Metadata about a source document (before fetching content) -pub struct SourceDocument { - pub doc_id: String, // source-specific unique ID - pub title: String, // human-readable title - pub source_uri: String, // canonical URI (file://, https://, paperless://) - pub content_hash: Option, // if source provides hash, skip fetch on match - pub mime_type: String, // text/markdown, application/pdf, etc. - pub updated_at: Option, -} - -/// Fetched document content ready for chunking -pub struct DocumentContent { - pub doc_id: String, - pub text: String, // extracted text (markdown preferred) - pub source_uri: String, - pub content_hash: String, // sha256 of text content - pub metadata: HashMap, // source-specific metadata -} - -/// Source health status -pub struct SourceHealth { - pub reachable: bool, - pub document_count: Option, - pub last_error: Option, -} -``` - -### Connector registry - -Connectors are registered at startup from a YAML config file. Adding a new source is: implement the trait, register the kind, add a config block. - -```yaml -# connectors.yaml — source connector configuration -connectors: - - kind: obsidian - name: homelab-vault - config: - root: /data/vault # local path (PVC mount or git-sync) - extensions: [md, markdown, txt] - exclude_dirs: [.obsidian, .trash] - - - kind: paperless - name: homelab-paperless - config: - base_url: http://paperless-ngx.paperless.svc.cluster.local:8000 - token_secret: paperless-api-token # k8s secret name - tags: [reference, manual, runbook] # only sync docs with these tags - format: markdown # request markdown export - - - kind: git_repo - name: infra-docs - config: - repo_url: https://forgejo.riotpiao.com/rock/homelab-docs.git - branch: main - sync_interval: 1h - paths: [docs/, runbooks/] - - - kind: s3 - name: backup-docs - config: - endpoint: https://minio.riotpiao.com - bucket: knowledge-base - prefix: docs/ - access_key_secret: minio-credentials -``` - -### Sync framework - -The connector trait provides enumeration and fetch. The **sync framework** handles everything else: - -1. **Change detection:** Compare `content_hash` from `list_documents()` against last-known hash in the manifest. Skip unchanged docs (zero embed calls). -2. **Chunking:** Route through existing `ChunkPolicy` — heading-based for markdown, paragraph-based for plain text, configurable per connector. -3. **Tombstoning:** Documents that vanish from `list_documents()` get tombstone records in the log. Append-only, never delete. -4. **Drift reporting:** `mem source status` shows per-connector: docs total, changed, new, removed — without mutating anything. -5. **Rate limiting:** Configurable fetch concurrency per connector (don't DDoS paperless with 500 parallel fetches). -6. **Resume:** Sync is resumable. Crash mid-sync, restart, only unseen docs are processed. - -``` -mem source sync --all # sync all registered connectors -mem source sync --name homelab-vault # sync one connector -mem source status # drift report, no mutations -mem source list # registered connectors + health -mem source add --kind paperless ... # register new connector -mem source rm --name old-source # deregister + tombstone -``` - -### Built-in connectors (shipped with binary) - -| Kind | Source | Protocol | Status | -|------|--------|----------|--------| -| `obsidian` | Local Obsidian vault | filesystem (walkdir) | M7.2 | -| `paperless` | paperless-ngx | REST API (`/api/documents/`) | M7.3 | -| `git_repo` | Git repository | git clone/pull | M7.4 | -| `s3` | S3-compatible storage | S3 API (minio, AWS) | M7.5 | -| `pi_session` | Pi agent sessions | filesystem (existing) | M7.1 (wrap existing) | -| `claude` | Claude transcripts | filesystem (existing) | M7.1 (wrap existing) | - -### How connectors interact with levels - -**Session connectors** (pi, claude) produce evidence that flows through the gated loop → L0/L1/L2. These are the existing `RecordSource` implementations, wrapped in `SourceConnector` for unified management. - -**Document connectors** (obsidian, paperless, git, s3) produce reference material → Level R. These bypass the gated loop entirely (no standing question, no gate decision). This is the existing M3.6 design, now generalized. - -The connector kind determines the pipeline: -``` -Session connector → RecordSource → ChunkPolicy → GatedLoop → L0/L1/L2 -Document connector → SourceConnector → ChunkPolicy → Level R (no gate) -``` - -### paperless-ngx integration (concrete example) - -paperless-ngx is already running in the cluster. It has: -- REST API at `http://paperless-ngx.paperless.svc.cluster.local:8000/api/` -- Documents with tags, correspondents, document types -- Full-text content available via API -- Thumbnail and original file access - -```rust -pub struct PaperlessConnector { - base_url: String, - token: String, - tag_filter: Vec, -} - -#[async_trait] -impl SourceConnector for PaperlessConnector { - fn kind(&self) -> &str { "paperless" } - fn name(&self) -> &str { &self.name } - - async fn list_documents(&self) -> Result> { - // GET /api/documents/?tags__name__in=reference,manual - // Paginate through results - // Return doc_id, title, checksum (paperless provides this) - } - - async fn fetch_document(&self, doc_id: &str) -> Result { - // GET /api/documents/{id}/ - // Extract content field (full text) - // Or GET /api/documents/{id}/download/ for original - } - - async fn health_check(&self) -> Result { - // GET /api/ — check 200 - } -} -``` - -### Obsidian vault as a connector - -The Obsidian vault is the **primary reference source**. It is human-maintained, git-backed, and the canonical location for runbooks, procedures, and domain knowledge that agents need. - -Deployment options: -1. **Git-sync sidecar:** A sidecar container clones the vault repo into a shared PVC. Memory service reads from the PVC. -2. **Local mount:** For development, mount the vault directory directly. -3. **API upload:** Push vault changes to memory service via HTTP. - -The Obsidian connector wraps the existing `DocCorpusSource` (M3.6.1) with the `SourceConnector` interface, adding change detection and registry management. - -### Future extensibility - -Adding a new source requires: -1. Implement `SourceConnector` trait (~100-200 lines) -2. Register the `kind` in the connector factory -3. Add config block to `connectors.yaml` -4. Run `mem source sync --name new-source` - -No changes to the ingest pipeline, chunking, embedding, storage, or query layers. The connector is the only new code. - -## Reference corpora — the non-evidential tier - -`RecordSource` takes session transcripts, and the update gate asks "does this chunk contain evidence for Q". A `kubectl` or `tea` cheatsheet answers neither question: it has no session, no turn, and no evidence. Left alone the system faithfully retains *what happened when a model used a tool badly* and never learns the tool. Level **R** closes that gap, and the shape of the fix matters more than the fact of it. - -**Reference text bypasses the gated loop entirely.** It is not evidence, so it gets no gate decision, never becomes L0, and never parents an L1. It is embedded, indexed, retrievable, and inert with respect to the recurrence. The update-rate that `M1.8` watches must not move when a corpus is added — `M3.6.6` asserts exactly that, because a design where documentation quietly enters the gate is the memory-explosion failure wearing a different hat. - -Four rules, each with an assertion behind it: - -1. **R is never a parent.** An `L1 -> R` or `L2 -> R` edge is a bug, not a provenance nuance — it lets upstream doc prose be cited as evidence for what happened in this cluster. `mem verify` rejects it. -2. **R is opt-in at query time.** Default levels stay `L1,L2`. `--levels R` is an explicit ask. A default that blends manual pages into project answers makes the memory sound like documentation, which is precisely what the tier model exists to prevent. -3. **The log stays authoritative.** Corpus ingest writes `Reference` records carrying source URI and content sha; the pgvector rows and vault notes are projections and must survive `mem rebuild --from-log` byte-identically, same as every other level. -4. **Re-ingest replaces, never appends.** Upstream docs change. Identity is `(source_uri, sha256)`: an unchanged sha is a no-op, a changed one tombstones the prior node in the log and writes its successor. Skip this and the index accumulates every historical revision of a cheatsheet, with recall drifting toward the oldest copy. - -**The fork is structural, not a flag.** `run_loop` takes a `Query`, and M1.2 makes an empty question a *load error* — the update gate is defined as "does this chunk contain useful information about the problem", so with no `Q` it has no referent. A corpus has no standing question, therefore a corpus ingest cannot construct a legal call into the recurrence at all. `mem ingest` and `mem ref add` are separate pipelines sharing `RecordSource` and `mem-chunk` and diverging *before* the controller. Encode that in the types — a reference chunk has no `run_loop` overload — rather than a `skip_gate: bool`, which is one careless default away from feeding documentation to the gate. - -**Why that matters to M1.8 specifically.** Update-rate is `chunks_used / chunks_seen` over a run, and the M1 gate fails above 30%. Documentation is evidence-free with respect to almost any project question, so routing a corpus through the controller would *lower* update-rate and make the threshold easier to clear while the system got worse. A gate metric that improves when you add unrelated text has stopped measuring what it claims. `M3.6.6` asserts that a corpus ingest leaves `chunks_seen` untouched, and that is the assertion protecting M1.8 from being gamed by accident. - -**The retrieval cycle is the skills cycle wearing a different hat.** A retrieved R section lands in an agent's context, appears verbatim in that session's transcript, and returns as L0 evidence — the exact loop M4.2 exists to break, with upstream docs in place of emitted skills. R text therefore registers in the same artifact manifest M4.2 reads, and this is why the phase is ordered *after* skills rather than before: the shingle matcher already exists by then. Without it, memory learns the man page as though it were a project finding. - -**No exit gate, no memory budget, no `M_t`.** R has none of the recurrence's state. Nothing about a corpus is bounded by 1024 tokens, nothing records `E_t`, and nothing appears in the M5 training corpus as a gate decision — because no decision was made. A corpus that shows up in `mem label` output is a bug in the export filter, not a labelling question. - -**Abstention comes with it.** A corpus multiplies the documents that are *somewhat* related to any question, so an unconditional top-k starts returning confident-looking prose for questions the memory cannot answer. `mem query` gains a relevance floor: below threshold it reports insufficient recall and returns nothing rather than the least-bad row. Worth having independently of R; `M3.6.5` builds it here because R is what makes it urgent. - -**What this does not do.** It does not make a 35B model competent at a tool in the abstract — retrieval puts the right page in context, nothing more. Skills (M4) remain the procedural path, and a skill drafted from a session where the tool actually failed still beats a retrieved man page. R is the floor, not the ceiling. - -## Tool context — the assembly surface - -The consumer that made this necessary is the orchestrator (`Poimen/workflows`): its `ImplementerActivity` renders a prompt ending in *"use the available tools to implement this task"* while naming none, and `PrepareSkillsActivity` clones one static skill list for every task regardless of what the task is. Both models behind it — `reasoning` and `ornith:35b` — are then asked to operate tooling they were never told about. Memory owns the fix because the alternative is a second retrieval stack inside the orchestrator, indexing the same corpus against the same embedder, drifting immediately. - -**Memory describes tools. It never executes them.** The orchestrator holds the sandbox, the credentials and the blast radius. This repo holds the catalog, the knowledge and the history. - -**No tool catalog lives here.** An earlier draft had memory serving MCP schemas so a prompt builder could enumerate tools. That is duplication — `pi` and any other caller already hold their own MCP connections and schemas, and a second copy drifts. Memory answers *what do we know about this*, keyed by a tool name, a task, or a raw failure. The caller knows what tools it has. - -### Retrieval: three tiers, cheapest first - -The input is usually not a question. It is a 50KB CI log, or a tool name. Three problems follow, and plain top-k cosine handles none of them. - -**Query/document asymmetry.** An L1 is written as an *answer* — "requests over 10KB failed because Kong buffered the body; fixed with `proxy-body-size: 0`". The query arrives as a *symptom* — `413 Request Entity Too Large`. Same incident, different register, mediocre cosine neighbours. This is the main reason retrieval that passes its unit tests disappoints in use. The fix is a second vector per memory (`kind='symptom'`, M3.7.8) generated at write time, describing the failures that memory would explain. Query-time HyDE solves the same problem by putting an LLM call on every lookup; writes are rare here because the gate keeps acceptance sparse, so paying once at write is the right side of the trade. - -**The input needs reducing before it can be embedded.** Signature extraction (M3.7.7) strips run ids, timestamps, workspace paths, shas, line numbers and durations, then hashes. Normalisation quality decides whether the exact tier ever fires — and when it silently does not, vector search still returns *something*, so the failure is invisible without the ablation the gate runs. - -**Failures repeat verbatim; prose does not.** `npm ERR! ERESOLVE unable to resolve dependency tree` is byte-identical across occurrences, so it deserves a hash lookup rather than a vector search. - -| Tier | Mechanism | What a hit means | -|---|---|---| -| 1 | `sig_sha` primary key on `failure_signature` | this exact failure happened here before | -| 2 | vector over `kind='symptom'`, then `kind='text'`, reranked | something similar happened | -| 3 | R reference corpus | nobody here has hit this; here are the docs | - -Tier 1 leads, it does not short-circuit — an exact hit plus two related memories beats an exact hit alone, and the extra tiers cost milliseconds against the caller's own inference. **The tier is a field in the response**, because "we hit this in July" and "the manual says" must not arrive in the same register. - -**Scope differs by tier.** Signature and symptom lookups federate across projects — an `ERESOLVE` lesson is not homelab-specific — while task-shaped queries stay project-scoped. Project match is a rank boost, not a filter. - -**Superseded memories are excluded, not demoted.** Kong is retired; a lesson about its buffer settings is wrong rather than stale, and `memory_supersede` surfaces the successor instead. - -### The bundle is a composition, and stores nothing new - -`POST /memory/context` takes any of `tool`, `task`, `signature_source` and merges the tiers above with matched skills. Each leg degrades independently — a skills timeout returns `[]` and a 200. No leg failure justifies a 5xx: a thinner answer beats no answer when someone is mid-incident. - -### Learned beats documented, and that ordering is the whole point - -When a task mentions `kubectl`, the bundle must surface *"`--all` is not a flag — it failed on 2026-08-19, the working form was `--all-namespaces`"* **above** the generic cheatsheet section. L1/L2 outrank R at equal rerank score, deliberately and by rule. - -Without that ordering this whole repo reduces to a documentation server, and the gated recurrence — the expensive part, the part with a 3B controller and a post-training phase behind it — contributes nothing at the moment a task is actually being implemented. R is the fallback for what nobody here has learned yet. - -### The feedback loop is the actual answer to "make ornith better at tools" - -A cheatsheet is a floor. The mechanism that improves is this one: - -``` -implementer emits a bad invocation - → fails, judge rejects, lessons injected, retry - → session ingested at end - → standing query `tool-failures` gates it in as evidence <- real evidence, unlike docs - → L1 memory: what failed, the error, the working form - → next task's /memory/context surfaces it above the docs -``` - -Note where this sits relative to the gate: tool failures are *genuine evidence about what happened in this project*, so unlike reference corpora they belong **inside** the recurrence and pass through the update gate normally. No bypass, no special casing — the only new artifact is a standing question (`M3.7.5`) whose answers happen to be operationally useful at task time. - -### Budget is a hard contract, not a hope - -The bundle is injected into every implementer prompt and `OLLAMA_CONTEXT_LENGTH` is 32768 — a verified constraint above, not a theoretical one. The bundle carries an explicit token budget with a fixed truncation order: - -1. drop **tier 3 (R)** first — upstream docs are the most replaceable content here -2. then trim **tier 2** toward the relevance floor -3. then drop **skills** -4. **never** drop **tier 1** — an exact prior occurrence is the smallest and most valuable thing in the response - -A response that cannot fit its tier-1 hits inside the budget is an error, not a truncation. - -## Phases - -**P1 — Read-only spine.** `mem-ingest` implements `RecordSource` for pi sessions and Claude transcripts; `mem-chunk` chunks to 5000 tokens on message boundaries; `mem ingest --dry-run` prints the chunk plan with no model calls. Both sources are batch, but they go through the stream interface so the seam is exercised from the first commit rather than retrofitted. - -**P2 — Gated loop at L1, prompted only.** `mem-llm` + gate-response parser (paper Figure 10a prompt, adapted for standing queries). Writes the JSONL log with L0 evidence and L1 memory records. Exit gate recorded, not acted on. This is the paper's "w/o RL" baseline, which Figure 9 shows already works. - -**P3 — Projections.** Obsidian projector and pgvector repo, both rebuildable via `mem rebuild --from-log`. Infra commit for `memory-db`. - -**P4 — L2 synthesis and retrieval.** `mem synthesize` runs the same loop over L1 memories with the exit gate on. `mem query` — embed, HNSW recall by level, rerank, return with provenance walked through `memory_edge`. - -**P5 — Skill drafting.** `mem skill draft --from ` emits `vault/skills/_drafts//SKILL.md` with `generated_from` provenance; `mem-ingest` grows the `derived: true` exclusion filter. Promotion stays manual. Cheap to build and it is the phase that makes the memory *do* something rather than only be read. - -**P5.5 — Reference corpora (board `M3.6`, ordered after skills).** `DocCorpusSource` implements `RecordSource` over a documentation tree, chunked on heading boundaries rather than message boundaries; R nodes land in log, index and vault; `mem ref add/list/sync/rm` manages corpora with replace-on-change identity; R text registers in M4.2's artifact manifest so retrieved docs cannot re-enter as evidence; `mem query` gains filter-then-recall over levels and a relevance floor. Ordered after P5 for two reasons: skills are the better answer to the same problem and should be built first, and the cycle guard is an extension of M4.2 rather than a parallel mechanism. The gate proves update-rate is unmoved, no L1 acquired an R parent, and no R text reached the controller. - -**P5.6 — Tool context (board `M3.7`).** Signature extraction reduces a failure log to a stable hash; a symptom projection gives every L1/L2 a second vector so an error message can find an answer written as prose; `POST /memory/context` serves the three tiers — exact signature, symptom similarity, reference docs — with skills matched alongside, under a hard budget. A `tool-failures` standing query feeds real invocation failures back through the gate, so tier 2 becomes tier 1 the second time something breaks. Consumers are `pi`, curl, or an MCP call; this phase ships no tool execution and no tool catalog. - -**P6 — Post-training (separate, Python).** Boundary is the JSONL. `mem label` uses the 32B `reasoning` model as an offline evidence labeler to produce per-chunk `U_t` ground truth (the paper had synthetic NIAH labels; we do not, and this is the honest cheapest substitute). Then verl trains a LoRA with the paper's rewards: `r_update` ±1, `r_exit` {0, −0.5 late, −0.75 early}, strict `r_format`, `α=0.9` mixing trajectory- and turn-level advantage. Requires the vLLM decision above. - -**P7 — Source connectors (board `M7`).** Generalizes the ingestion layer from hardcoded file sources to an extensible `SourceConnector` trait with a YAML-driven registry. Existing sources (pi sessions, Claude transcripts, `DocCorpusSource`) are wrapped in the new interface; new sources (paperless-ngx, git repos, S3) implement the trait directly. The sync framework handles change detection, tombstoning, drift reporting, and resumable sync for all connectors. The connector is the only new code when a source is added — no changes to chunking, embedding, storage, or query layers. Ordered after M3.6 because it generalizes `mem ref` rather than duplicating it, and after M4.2 because document connectors must register in the derived-content manifest to prevent cycle contamination. - -## Task breakdown - -Board lives in **`memory-tasks/`** at the repo root. Format follows `agent-rust/tasks/`: one file per task, self-contained, each with `Acceptance` / `Verify` (harness, numbered assertions, command) / `False pass` / `Traps`, a `Status` field as source of truth, and `memory-tasks/INDEX.md` mirroring it.

Kong is **removed** from the cluster. - -**Auth:** Authentik (OIDC provider) → Vault (OIDC auth method, `auth/oidc/role/homelab-admin`, bound on `permissions: "*"` claim) → Vault token → service validates token. Memory service currently uses placeholder `apikey` header — M3.5.10 replaces this with Vault token validation. - -**Architecture assumption:** Memory services run in CNPG cluster; API layer is HTTP facade exposing read/write workflows to distributed agents.

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.

Mitigation: P2's update-rate is a cheap early read, and the 32B `reasoning` model can spot-audit a sample before committing to P5. -- **L2 inherits L1's errors with no path back to source.** Synthesis over memories cannot recover evidence the L1 gate wrongly discarded. `memory_edge` makes the omission *visible* (an L1 note with suspiciously few parents) but not recoverable without a re-run. -- **Self-reinforcement through skills.** The only cycle in the system: emitted skill → future session context → ingested as evidence → reinforces the memory that emitted it. Guarded by manual promotion plus the `derived: true` ingest filter, and both must hold. Audit it by checking that no L0 evidence node's text matches an emitted artifact. -- **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. -- **Reference corpora are inert by construction, and that is a real limit.** `M3.6` makes documentation retrievable as level R, but R never becomes evidence and never parents an L1, so it can improve recall and nothing else — synthesis quality is untouched by adding a corpus. Tool competence still arrives mainly through M4 skills drafted from real sessions. Skipping M3.6 entirely leaves a working system that simply has nothing to say about a tool until someone has used it badly in a logged session. -- **R inflates the index against a fixed recall width.** `mem query` recalls 10×k before reranking. A large corpus competes for those slots with genuine L1/L2 answers even when R is excluded by the level filter, unless the filter is pushed into the HNSW query rather than applied after it. Filter-then-recall, not recall-then-filter; `M3.6.4` asserts the ordering. -- **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. diff --git a/README.md b/README.md index db9f3d0..5612cf6 100644 --- a/README.md +++ b/README.md @@ -1,463 +1,101 @@ -# Poimen Memory +# Poimen Memory System -> **Poimen** (ποιμήν) — Greek for "shepherd".

Use the reference timestamp as the current time when determining the valid_at and invalid_at dates. +3. If the fact is written in the present tense, use the Reference Timestamp for the valid_at date. +4. If no temporal information is found that establishes or changes the relationship, leave the fields as null. +5. Do not infer dates from related events. Only use dates that are directly stated to establish or change the relationship. +6. For relative time mentions directly related to the relationship, calculate the actual datetime based on the reference timestamp. +7. If only a date is mentioned without a specific time, use 00:00:00 (midnight) for that date. +8. If only year is mentioned, use January 1st of that year at 00:00:00. +9. Always include the time zone offset (use Z for UTC if no specific time zone is mentioned). + +Return JSON format: +{ + "valid_at": "ISO8601_datetime_or_null", + "invalid_at": "ISO8601_datetime_or_null" +} +"#;

Compression - itself uses deterministic algorithms (no LLM calls in hot path). - -2. **Search indexes untouched.** Compression happens AFTER retrieval. pgvector - and OpenSearch see full-fidelity text. Only the LLM prompt is optimized. - -3. **Reversible via CCR.** Every compression is reversible. The model can - request full originals via hash lookup.

-### Common Issues - -#### ❌ Pods not starting - -**Symptom:** `Pending` or `CrashLoopBackOff` - -**Check:** -```bash -kubectl describe pod -n poimen opensearch-0 -``` - -**Common Causes:** -1. **vm.max_map_count too low** → Init container should fix (wait 30s) -2. **PVC not provisioned** → Check Longhorn: `kubectl get pvc -n poimen` -3. **Memory limit exceeded** → Increase `limits.memory` in StatefulSet -4. **Node affinity** → Check node labels: `kubectl get nodes --show-labels` - -**Fix:** -```bash -# Force pod recreation -kubectl delete pod -n poimen opensearch-0 -# Scheduler will restart it - -# Check logs after restart -kubectl logs -n poimen opensearch-0 --tail=100 -``` - -#### ❌ Cluster status = yellow - -**Symptom:** Only 1 node showing, shards unassigned - -**Cause:** Waiting for second node to start (normal during initial deployment) - -**Fix:** Wait 1-2 minutes -```bash -# Watch until green -kubectl get pods -n poimen -l app.kubernetes.io/name=opensearch -w -``` - -#### ❌ Cluster status = red - -**Symptom:** Cluster health = red, both nodes showing but unhealthy - -**Debug:** -```bash -# Check node logs -kubectl logs -n poimen opensearch-0 --tail=200 | grep -i error - -# Check if nodes can communicate -kubectl exec -n poimen opensearch-0 -- curl http://opensearch-1.opensearch.poimen.svc.cluster.local:9300/ -``` - -**Common Causes:** -- Network Policy blocking communication -- Disk/memory pressure -- JVM out of memory -

-### How OpenSearch validates JWT - -1. **Token arrives**: `Authorization: Bearer eyJh...` -2. **OpenSearch extracts**: Token after "Bearer " -3. **Validates signature**: Using JWKS from Authentik -4. **Extracts claims**: `sub`, `roles`, `permissions` -5. **Maps to user**: Creates internal user from JWT -6. **Checks permissions**: Verifies access to indices - -### JWT Claims Expected - -```json -{ - "iss": "https://authentik.riotpiao.com/application/o/poimen-memory/", - "aud": "opensearch", - "sub": "user@example.com", - "roles": ["read_vault", "write_vault"], - "permissions": ["memory:read", "memory:write"], - "exp": 1234567890, - "iat": 1234567800 -} -``` - -### Update Authentik OAuth2 App - -Ensure the poimen-memory app includes custom claims: - -``` -Scope: openid email profile -Custom Claims: - - roles: ["memory:read", "memory:write"] - - permissions: ["memory:read", "memory:write"] -``` - -## Step 6: Role-Based Access Control (RBAC) - -### Available Roles in OpenSearch - -```yaml -read_vault: - - Can search vault indices - - Can read documents - - No write permissions - -write_vault: - - Can index new documents - - Can update existing - - Can read documents - -all_access: - - Full cluster access - - Admin role -``` - -### Map JWT Roles to OpenSearch Roles - -Edit `internal_users.yml` in ConfigMap: - -```yaml -authc: - realms: - jwt_realm: - type: jwt - roles_key: roles # Extract "roles" claim from JWT - claims_mapping: - principal: sub - roles: roles -``` - -### Test role enforcement - -```bash -# User with read_vault role only -curl -X GET "https://localhost:9200/vault-*/_search" \ - -H "Authorization: Bearer " -# ✅ Success (read allowed) - -curl -X PUT "https://localhost:9200/vault-test/_doc/123" \ - -H "Authorization: Bearer " \ - -d '{"content": "test"}' -# ❌ 403 Forbidden (write denied) -``` - -## Step 7: Monitoring & Troubleshooting - -### Check OpenSearch logs - -```bash -kubectl logs opensearch-0 -n poimen -f --tail=50 -``` - -### JWT validation errors - -If you see "JWT verification failed": - -1.
