# M3.7.4 — `/memory/context` — three-tier lookup
| Field | Value |
|---|---|
| Phase | M3.7 — Tool context |
| Size | M — 1–3 days |
| Status | ⬜ Not started |
| Flags | — |
| Spec | inlined below |
| Blocks | M3.7.6 |
| Depends | M3.7.3, M3.7.7, M3.7.8, M3.5.3, M3.6.5 |
## Goal
One call that answers “what do we already know about this failure, tool or task”,
cheapest tier first, and says which tier the answer came from.
## Existing code to build on
**`crates/mem-core/src/lesson.rs`** already implements the tier-1 and tier-2 lookup pattern:
| Function | What it does | Reuse plan |
|---|---|---|
| `lookup(sig, lessons, floor)` | Exact hash match (tier 1) then trigram similarity (tier 2) with abstention floor | **Extend**: add vector search (M2.1) as tier 2, keep trigrams as offline fallback |
| `Tier` enum (`Exact`, `Similar(f32)`) | Tier labeling | **Extend**: add `Reference` variant for tier 3 |
| `Hit` struct | `{ lesson, tier }` | **Extend**: generalize from `Lesson` to `MemoryNode` |
| `similarity(a, b)` | Jaccard over character trigrams | **Keep** as fallback when embeddings unavailable |
| `render_injection(hit, max_chars)` | Capped injection text | **Reuse** for budget management |
**`crates/mem-cli/src/lessons_cmd.rs`** already implements:
| Command | What it does | Reuse plan |
|---|---|---|
| `mem lookup --tool T --file F` | CLI tier-based lookup with floor | **Model for** the HTTP endpoint |
## Files
| Action | Path |
|---|---|
| **Exists** | `crates/mem-core/src/lesson.rs` — `lookup()`, `Tier`, `Hit`, `similarity()` |
| **Exists** | `crates/mem-cli/src/lessons_cmd.rs` — `mem lookup` CLI |
| Create | HTTP endpoint in `mem-api` crate (M3.5.1 server) |
| Modify | `crates/mem-core/src/lesson.rs` — extend `Tier` enum with `Reference` variant |
| Create | `tests/it_context_endpoint.rs` — integration tests (12 assertions) |
## Facts (inlined — no spec read needed)
```
POST /memory/context
{ "tool": "github-actions",
"signature_source": "<50KB run log>",
"project": "homelab", "scope": "all-projects", "budget": 6000 }
→ 200 {
"tier": 1,
"lessons": [
{"tier":1,"level":"L1","seen_count":3,"last_seen":"2026-07-02",
"text":"peer dep conflict @types/react 18 vs 19; npm ci --legacy-peer-deps
unblocks, real fix is pinning in overrides",
"parents":[{"level":"L0","source":"pi:…"}]},
{"tier":2,"level":"L2","score":0.71,"matched_kind":"symptom","text":"…"}
],
"skills": [{"name":"ci-triage","score":0.77}],
"budget": {"limit":6000,"used":2140,"dropped":[]}
}
```
Three accepted inputs, any combination: `tool`, `task`, `signature_source`. At
least one is required; `signature_source` without `tool` is allowed and the tool
is inferred by the extractor's rule match.
**Tiers, cheapest first:**
| Tier | Mechanism | Meaning |
|---|---|---|
| 1 | `sig_sha` primary-key hit 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 does not short-circuit tiers 2 and 3 — it *leads*. An exact hit plus two
related memories is a better answer than an exact hit alone, and the tiers cost
milliseconds relative to the caller's own inference.
**`tier` is in the response and this matters.** The caller, and the human reading
its output, must be able to tell "we hit this exact error in July" from "here is
what the manual says". Presenting tier 3 in the register of tier 1 is how a
retrieval system becomes untrustworthy.
**Ordering is by tier, then rerank, and never by raw score.** A cheatsheet is
written to match the phrasing of a question and will routinely out-score the
terse memory that actually solved it. Precedence is a rule: tier 1 > L1/L2 > R.
**Scope defaults differ by tier.** Signature and symptom lookups federate across
projects — `ERESOLVE` is not homelab-specific — while task-shaped queries stay
project-scoped unless asked otherwise. Project match becomes a rank boost, not a
filter.
**Superseded memories are excluded, not demoted.** A lesson about Kong config is
wrong now, not merely old. M2.4 filters them at the repository; this endpoint
surfaces the successor if one is linked.
**Budget, fixed truncation order:** drop R, then trim tier-2 results toward the
floor, then drop skills. Tier-1 hits are never dropped — they are the smallest and
most valuable content in the response.
**Legs degrade independently.** A skills timeout returns `"skills":[]` with a
`degraded` note and a 200. There is no leg whose failure justifies a 5xx here; a
thinner answer beats no answer when someone is mid-incident.
## Steps
1. Route in the M3.5.1 server; accept `tool`, `task`, `signature_source`.
2. If `signature_source` present, extract and normalise (M3.7.7), then tier 1.
3. Tier 2 concurrently: symptom-vector search, then text-vector, merge, rerank.
4. Tier 3 only if tiers 1–2 leave budget unfilled.
5. Skills leg (M3.7.3) concurrently with tier 2.
6. Order by tier, apply precedence, apply budget, record drops.
7. On tier-1 hit, append an occurrence record to the log so `seen_count` grows.
8. One structured log line: tiers fired, latencies, scores, drops.
## Acceptance
- A previously-seen failure returns `tier: 1` with `seen_count` ≥ 2.
- An unseen but similar failure returns tier 2 with `matched_kind: "symptom"`.
- A wholly unknown failure returns tier 3 and says so.
- Tier 1 outranks a higher-scoring R result.
- Identical requests return byte-identical bodies apart from the occurrence side
effect.
## Verify
**Harness:** M3.5.1 test server over a store seeded with the poimen log, a
reference corpus, promoted skills, and signatures from replayed real failures.
Fault injection per leg.
**Integration test** — `tests/it_context_endpoint.rs`:
1. `a1_tier1_exact` — replay a failure already in `failure_signature`; assert
`tier: 1` and the correct memory.
2. `a2_tier1_counts_occurrence` — call twice; assert `seen_count` incremented and
an occurrence record is in the log.
3. `a3_tier2_symptom` — a novel wording of a known incident returns tier 2 with
`matched_kind: "symptom"`.
4. `a4_tier2_beats_text_only` — same query with symptom vectors deleted ranks the
correct memory lower; assert the symptom path strictly improves it.
5. `a5_tier3_fallback` — an unknown failure returns tier 3 and no lesson claims a
lower tier.
6. `a6_precedence_over_score` — seed an R node that reranks above a tier-1 hit;
assert the tier-1 hit still leads and the response exposes both raw scores.
7. `a7_superseded_excluded` — mark a memory superseded; assert it is absent and
its successor is present.
8. `a8_budget_order` — shrink the budget stepwise; assert drops occur R, then
tier 2, then skills, and that tier 1 is never dropped.
9. `a9_skills_degrade` — inject a skills timeout; assert 200, `[]`, `degraded`.
10. `a10_signature_without_tool` — omit `tool`; assert the extractor infers it.
11. `a11_scope_federation` — a signature seeded under another project is found
with `scope: all-projects` and not with `scope: project`.
12. `a12_used_matches_actual` — tokenize the body independently; assert equality
with `budget.used`.
**Command:** `cargo test -p mem-api context_endpoint`
**False pass:**
- Asserting tier 1 fires without asserting tiers 2 and 3 still populate. A
short-circuit passes assertion 1 and produces a thin answer in exactly the case
where the most context is available.
- Testing precedence on a fixture where the tier-1 hit also scores highest.
Assertion 6 is only meaningful when score and tier disagree.
- Testing degradation with an empty leg instead of a failing one. Timeouts take
the path that 500s in production.
## Traps
- Running tier 3 unconditionally. Reference chunks are long, they fill the budget,
and they push real memories out of a response that had better answers available.
- Incrementing `seen_count` on a retry. The orchestrator retries activities; an
occurrence should key on the caller's request id or the count inflates and
`last_seen` stops meaning anything.
- Returning tier as a label the caller has to interpret from ordering. It is a
field; if it is implicit, every consumer reimplements the inference differently.

# M3.7.6 — M3.7 composition gate
| Field | Value |
|---|---|
| Phase | M3.7 — Tool context |
| Size | M — 1–3 days |
| Status | ⬜ Not started |
| Flags | gate |
| Spec | inlined below |
| Blocks | all of M3.7 |
| Depends | M3.7.3, M3.7.4, M3.7.5, M3.7.7, M3.7.8 |
## Goal
Prove the lookup answers real failures from history rather than handing back
documentation, and that adding it changed nothing upstream.
## Facts (inlined — no spec read needed)
The phase's claim is narrow and testable: **given a failure this project has
solved before, the lookup returns the fix.** Everything else is machinery in
service of that.
**The measurement is a replay, not an A/B.** Collect real failures with known
resolutions from session history and CI. Hold out half. Ingest the first half,
then replay *all* of them against `/memory/context` and score:
| Signal | What it proves |
|---|---|
| tier-1 hit rate on ingested failures | signature normalisation actually stabilises (M3.7.7) |
| tier-2 recall on held-out failures | symptom projections generalise beyond exact repeats (M3.7.8) |
| tier-3 rate on ingested failures | how often the system falls back to docs when it should have known |
A high tier-3 rate on failures already in the corpus is the phase failing, and it
is the number to watch. It means retrieval exists and does not fire.
**No dependency on the orchestrator.** The consumer is any HTTP client — `pi`,
curl, an MCP call. Nothing here requires `Poimen/workflows` to execute tool calls,
which is what made the earlier version of this gate unrunnable.
**Upstream must be undisturbed.** This phase adds a standing query
(`tool-failures`), a second vector kind, and two tables. Each can perturb things
that were green: update-rate for M1.8, recall width for M3.6.6, rebuild parity for
M2.8. Re-assert all three.
**Cost belongs in the result.** The lookup sits in front of real work. Report p50
and p95 for each tier separately — a 900ms tier-2 is a different product than a
40ms tier-1, and the averages hide it.
## Steps
1. Assemble ≥40 real failures with known resolutions across ≥4 tools; commit the
set before running anything.
2. Split 50/50 into ingested and held-out.
3. Ingest the first half through the normal path — sessions, `tool-failures`
standing query, gate, symptom projections, signatures.
4. Replay all 40 against `/memory/context`; record tier, rank of the correct
answer, latency.
5. Re-run M1.8, M2.8 and M3.6.6.
6. Emit `expected/m3.7-gate.txt` with per-tool tier rates and latency
percentiles; commit it, same rule as M1.8.
## Acceptance
- Tier-1 hit rate on ingested failures ≥ 0.80.
- Tier-2 returns the correct memory in the top 3 for ≥ 0.50 of held-out failures.
- Tier-3 rate on ingested failures ≤ 0.10.
- M1.8, M2.8 and M3.6.6 unchanged except for the added standing query.
- Tier-1 p95 under 50ms; tier-2 p95 under 500ms.
## Verify
**Harness:** live gateway, real database, the committed failure set. Long-running,
`#[ignore]` by default, same posture as M1.8.
**Integration test** — `tests/it_m3_7_gate.rs`:
1. `a1_tier1_hit_rate` — replay the ingested half; assert ≥ 0.80 return tier 1,
print per-tool.
2. `a2_tier3_rate_bounded` — on that same half, assert ≤ 0.10 fall through to
tier 3. This is the "retrieval exists but never fires" detector.
3. `a3_heldout_recall` — the held-out half; assert the correct memory is in the
top 3 for ≥ 0.50, proving symptom projections generalise rather than memorise.
4. `a4_symptom_ablation` — delete `kind='symptom'` vectors, re-run `a3`; assert
recall drops measurably. Without this, `a3` could be satisfied by the text
vector alone and M3.7.8 would be dead weight.
5. `a5_signature_stability` — for failures appearing more than once in the set,
assert every occurrence produced the same `sig_sha`.
6. `a6_precedence_held` — across the whole replay, assert no response placed an R
result above a tier-1 or tier-2 lesson.
7. `a7_m1_8_unchanged` — re-run M1.8; per-query numbers match the committed
baseline, `tool-failures` the only addition.
8. `a8_m2_8_rebuild` — drop and rebuild with vectors, signatures and supersede
rows present; assert byte-identical.
9. `a9_m3_6_6_still_green` — re-run the M3.6 gate in full.
10. `a10_latency_by_tier` — p50/p95 per tier; assert the two thresholds.
11. `a11_no_orchestrator_dependency` — run the whole gate with `Poimen/workflows`
absent; assert it completes.
**Command:** `cargo test --workspace m3_7_gate -- --ignored --nocapture`
**False pass:**
- Replaying the ingested half only. It measures memorisation; `a3` on held-out
data is the one that says anything about a failure you have not seen before.
- Skipping `a4`. A symptom index that is empty, or full of paraphrase, passes
every other assertion here — the ablation is the only proof it contributes.
- Counting a tier-1 hit without checking the returned memory is the *right* one.
A signature collision produces a confident wrong answer, which is worse than
tier 3.
- Building the failure set from failures the system already handles well.
Fix the set first, commit it, then run.
## Traps
- Curating resolutions after seeing what retrieval returns. The known-good answer
for each failure has to be written down before the first replay.
- Reading a low tier-1 rate as a retrieval problem. It is almost always
normalisation (M3.7.7); check `mem sig explain` on the misses before touching
anything downstream.
- Letting the ingested half leak into the held-out half through near-duplicate
failures. Split by incident, not by log file.

M3.7 Composition Gate Tests:
a1: Tier-1 hit rate ≥80% on ingested failures
a2: Tier-3 fallback rate ≤10% on ingested failures
a3: Tier-2 recall ≥50% on held-out failures
a4: Symptom vectors improve recall ≥10%
a5: Signature stability (repeats → same sig)
a6: Tier precedence (tier-1/2 > tier-3)
a7: M1.8 update-rate unchanged
a8: M2.8 rebuild parity maintained
a9: M3.6.6 reference corpus gate green
a10: Latency requirements (p95 tier-1<50ms, tier-2<500ms)
a11: No dependency on Poimen/workflows
