Without this the corpus slowly becomes its own training data. +## 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.

A model in the hot path of every lookup is both slow and +non-deterministic, and non-determinism here means the same failure hashes two +ways. + +**One signature, not a fingerprint set.** Take the *first* error that is not a +consequence of an earlier one.

A worse signature is still a +signature, and a lookup that 500s because the tool is unrecognised is useless in +exactly the situation someone needs it. + +## Steps + +1. `mem-core::signature` — `extract(tool, raw) -> Option`. +2. Rule sets for `github-actions`, `kubectl`, `npm`, `cargo`, `go`, `docker`; + a generic fallback for everything else. +3.

Cascade suppression: prefer the earliest error line not preceded by another. +6. `mem sig explain ` — print extracted signature, normalised form, hash + and which rule fired. This is the debugging surface for the whole tier. + +## Acceptance + +- The same failure from two different runs produces the same `sig_sha`. +- Two genuinely different failures from the same tool produce different hashes. +- An unrecognised tool still produces a signature. +- Extraction on a 50KB log completes in under 50ms with no model call. +- `mem sig explain` names the rule that fired. + +## Verify + +**Harness:** `fixtures/failures/` — for each of six tools, **two real logs of the +same failure from different runs**, plus one log of a different failure from the +same tool.

This is the assertion the tier depends on. +2. `a2_different_failure_different_hash` — the third log hashes differently. +3. `a3_normalisation_removes_volatiles` — assert the normalised string contains + no timestamp, path, sha, line number or duration, by regex. +4. `a4_cascade_picks_first` — a log with a root error followed by five induced + ones yields the root. +5. `a5_unknown_tool_fallback` — a log from an unlisted tool yields a signature and + names the generic rule. +6. `a6_no_model_calls` — run under a transport that panics on request; assert + every fixture extracts. +7. `a7_latency` — 50KB log extracts in under 50ms. +8. `a8_tool_in_identity` — the same normalised text under two different tools + hashes differently. +9. `a9_explain_names_rule` — `mem sig explain` output identifies the matching + rule for each fixture. + +**Command:** `cargo test -p mem-core signature` + +**False pass:** +- Fixtures generated by re-running the same command in the same directory at + nearly the same time.
