… (amd#1828)

## Summary

Procedural memory now keeps **one** proven recipe per goal even when the
distiller renames it between synthesis passes — recipes are matched by
meaning, not by an exact name string.

## Why

The procedural-memory tier (amd#887) promises "learn a task once, keep one
proven recipe, replace it when a better version appears." Supersession
is the *replace* half. But `reconcile_and_store` decided "same recipe?"
by exact-string match on `name` — and the distiller LLM authors a fresh
kebab name each pass (`DISTILL_TEMPERATURE = 0.1`, kebab-validated only,
never canonicalized). So a recurring goal that drifts from
`summarize-unread-emails` one pass to `summarize-my-unread-emails` the
next slipped past the name lookup: **before**, a drifted name produced a
*second* ADD and the supersede branch silently never fired — duplicates
accumulated, `recall_skill(top_k=2)` could surface two near-identical
copies into the planner prompt, and a genuinely better recipe coexisted
with the stale one instead of replacing it. **After**, reconcile matches
the nearest enabled, non-superseded procedure by `when_to_use` embedding
cosine `>= SIMILARITY_TAU` (0.82), so a drifted name still resolves to
the same recipe and supersession fires as designed. Go-forward only —
cleaning up rows already duplicated by prior drift is out of scope (the
feature is new and off-by-default).

## Linked issue

Closes amd#1818

## Changes

- **Match key is meaning, not name.** `reconcile_and_store` now finds
the prior recipe via a new pure helper `_nearest_enabled_procedure`
(cosine `>= similarity_tau` over `when_to_use` vectors), reusing the
embedding the call site already computes and passes as `embedding=` —
previously persisted but never used for matching. The
supersede-by-`success_count` dominance check, the
insert-new-then-`superseded_by` lineage, the ADD/UPDATE/NOOP shape, and
"never DELETE" are all unchanged; only the match source moved.
- **Live SQLite cosine pass, not the FAISS index** (per maintainer steer
in [issue amd#1818 comment
4772627749](amd#1818 (comment))).
The scan goes over `search_skills(..., with_embedding=True)`, which sees
rows written earlier in the *same* `max_clusters_per_pass` loop
(`put_skill` commits immediately) — the FAISS index isn't refreshed
until after reconcile returns, so reusing it could let a same-pass
double-ADD through. This also keeps `reconcile_and_store` a pure
function (`store`-only) that unit-tests without a live backend.
- **Fail-loud, no silent cap.** The scan is bounded by
`_RECONCILE_SCAN_LIMIT = 500`; saturating it logs a `warning` rather
than silently dropping rows. Degraded inputs
(missing/zero-norm/wrong-dim embeddings) are skipped with intent, not
swallowed.
- **No import-cycle regression.** Embedding BLOBs are decoded locally
with `np.frombuffer` so `skill_synthesis` imports no `memory` symbol,
preserving the `memory → procedural_memory → skill_synthesis` one-way
direction.

## Test plan

- [x] `python -m pytest tests/unit/test_skill_synthesis.py
tests/unit/test_memory_mixin.py tests/unit/test_memory_store.py -q` —
all green (578 passed locally), including the 4 new pure-fn tests, the
e2e two-pass drift test, and the 3 updated pure-fn tests.
- [x] `python util/lint.py --all` — black/isort/pylint/flake8 clean
(remaining MyPy/Bandit warnings are pre-existing and not in the touched
files).
- [x] **Regression check (optional but recommended):** revert the one
match line in `reconcile_and_store` to the old
`search_skills(name=candidate.name, …)` lookup and re-run the four
meaning tests — they must FAIL on the old code and PASS on the fix,
proving they exercise the changed branch (not vacuous).

> No `gaia eval agent` run is included — this is persistence-only (no
prompt, tool schema, recall path, model, or error-classification
change), and a cold eval runs from empty memory so it cannot reach the
multi-pass name-drift branch the fix targets. The deterministic unit +
e2e tests above exercise that branch directly.

## Deviations from the approved sketch

| Sketch / comment said | Code reality | Resolution |
|---|---|---|
| "search the procedures **FAISS index** (or a `search_skills` cosine
pass)" | `_proc_faiss_index` lives on the mixin and is refreshed only
*after* `reconcile_and_store` returns; the function is pure and takes
only `store`. | Took the offered **`search_skills` cosine pass** — keeps
the function pure/unit-testable and catches same-pass ADDs the index
wouldn't. No behavior gap vs the sketch. |
| Comment cites the call-site vector at `procedural_memory.py:86` |
After the amd#1794 extraction, the vector is computed at
[`procedural_memory.py:463`](src/gaia/agents/base/procedural_memory.py#L463)
and passed as `embedding=`. | Line-drift only; the vector exists and is
reused as the match input. |
| (none — net-new) | The existing pure-fn tests
`test_noop_when_existing_dominates` and
`test_update_supersedes_lower_success_count` seeded rows with **no
embedding** and relied on name equality. | Updated to seed matching
embeddings (the new match key) — they would otherwise ADD instead of
supersede. In-scope test churn. |

## Checklist

- [x] I have linked a GitHub issue above (`Closes amd#1818`).
- [x] I have described **why** this change is being made, not just what
changed.
- [x] I have run linting and tests locally (`python util/lint.py --all`,
`pytest tests/unit/`).
- [x] No user-visible/CLI/API surface changed — internal reconcile logic
only, so no docs update is required.

## Acceptance-criteria proof — amd#1818

The match key in `reconcile_and_store` moved from exact `name` to
`when_to_use` embedding cosine `>= SIMILARITY_TAU` (0.82) via a new
live-SQLite cosine pass `_nearest_enabled_procedure`
([skill_synthesis.py:580](src/gaia/agents/base/skill_synthesis.py#L580));
dominance, lineage, and never-DELETE are unchanged.

Every AC is proven by a **deterministic** test that exercises the
changed branch — and each is shown to **fail on the old name-match code
and pass on the fix** (regression proof below), which is what makes the
green meaningful.

### AC → proof map

| Acceptance criterion | Proving test(s) | Key assertions |
|---|---|---|
| **AC amd#1** — match by `when_to_use` cosine `>= SIMILARITY_TAU`, not
`name`; recurring goal → one enabled row under name drift |
`test_matches_by_meaning_supersedes_under_name_drift`
([:542](tests/unit/test_skill_synthesis.py#L542)),
`test_distinct_meaning_adds_even_with_same_name`
([:578](tests/unit/test_skill_synthesis.py#L578)) | drifted name +
cosine-1.0 vector → **1** enabled row; identical `name` + orthogonal
vector (cosine 0 < τ) → **2** rows (ADD). Proves the key is meaning, not
name. |
| **AC amd#2** — supersession fires under drift: higher-`success_count`
candidate supersedes (insert-new + `superseded_by`, never DELETE);
dominance unchanged |
`test_matches_by_meaning_supersedes_under_name_drift`
([:542](tests/unit/test_skill_synthesis.py#L542)),
`test_lower_success_same_meaning_noops`
([:597](tests/unit/test_skill_synthesis.py#L597)),
`test_update_supersedes_lower_success_count`
([:513](tests/unit/test_skill_synthesis.py#L513)),
`test_noop_when_existing_dominates`
([:494](tests/unit/test_skill_synthesis.py#L494)) | `action=="update"`,
`superseded_id==old_id`, old row kept with `superseded_by` set (never
deleted); weaker cluster under a drifted name → `noop` (dominance logic
intact under the new key). |
| **AC amd#3** — same cluster distilled twice with differing names →
exactly one surviving enabled, non-superseded row, second supersedes
first | `test_name_drift_across_passes_supersedes`
([test_memory_mixin.py:3331](tests/unit/test_memory_mixin.py#L3331)) —
two real `_synthesize_skills` passes | pass 1 ADDs
`summarize-unread-emails`; pass 2 (drifted `summarize-my-unread-emails`,
higher `success_count`) → `stored==1` (UPDATE); `search_skills()`
returns **1** row; pass-1 id `superseded_by` the pass-2 id. |

### Comment
[#4772627749](amd#1818 (comment))
refinements — both addressed

**1. "Live SQLite + cosine pass, not `_proc_faiss_search`"** (avoids a
stale-index same-pass double-ADD). `_nearest_enabled_procedure` scans
`store.search_skills(enabled_only=True, include_superseded=False,
with_embedding=True)` — the live table, never the FAISS index. Pinned by
a contract-shape spy:

> `test_reconcile_queries_store_by_embedding_not_name`
([:619](tests/unit/test_skill_synthesis.py#L619)) — asserts every
`search_skills` call passes `with_embedding=True, enabled_only=True,
include_superseded=False` and **`name` is always `None`**, so a silent
revert to name-matching (or to the index) is caught.

**2. "Assert the surviving row carries the *second* candidate's
name/body, not just count==1"** (catches a wrong-direction supersede).
Both the pure-fn and e2e AC tests assert name **and** body of the
survivor:
- pure-fn: `visible[0]["name"] == "summarize-my-unread-emails"` **and**
`visible[0]["markdown_body"] == "# New\n1. better step"`.
- e2e: `visible[0]["name"] == "summarize-my-unread-emails"` **and**
`"digest" in visible[0]["markdown_body"]`, plus `old[0]["superseded_by"]
== visible[0]["id"]`.

### Verbatim results

**All AC tests pass on the fix:**

test_matches_by_meaning_supersedes_under_name_drift PASSED
test_distinct_meaning_adds_even_with_same_name      PASSED
test_lower_success_same_meaning_noops               PASSED
test_reconcile_queries_store_by_embedding_not_name  PASSED
test_update_supersedes_lower_success_count          PASSED
test_noop_when_existing_dominates                   PASSED
test_name_drift_across_passes_supersedes PASSED (e2e, 2 synthesis
passes)
test_rerun_is_noop_and_never_deletes PASSED (never-DELETE)
8 passed in 1.28s



**Regression proof — the tests catch the bug** (temporarily revert the
match line to the old `search_skills(name=…)` lookup):

=== AC tests against OLD exact-name code — MUST FAIL ===
FAILED test_matches_by_meaning_supersedes_under_name_drift
FAILED test_distinct_meaning_adds_even_with_same_name
FAILED test_lower_success_same_meaning_noops
FAILED test_name_drift_across_passes_supersedes
4 failed in 1.05s

=== same 4 against the fix — MUST PASS ===
4 passed in 0.78s

Full suite for the touched modules: **578 passed**; `python util/lint.py
--all` → **ALL QUALITY CHECKS PASSED**.

PR title: test(tool-loader): pin amd#800 doc-profile data-vs-recall
disambiguation
Branch:    test/800-tool-collision-regression
-->

## Summary

Before this PR, amd#800's scratchpad/memory tool collision was resolved in
*code* (by the amd#688 dynamic tool loader, landed via amd#1449/amd#1450/amd#1451)
but **nothing pinned it** — no test asserted that the structured-data
tool and memory `recall` can't crowd each other out of the prompt, so
the fix could silently regress. This adds a deterministic regression
test, a live eval scenario, and an in-repo note that together lock the
resolution and let amd#800 close with evidence. No runtime code changes —
this is a closeout + regression, not a feature.

## Why

amd#800 is a coordination tracker: it exists to *prove* the collision is
fixed, not leave it as a known gap. The decisive finding (verified on
`main`) is that the literal pair in the title — `scratchpad.query_data`
vs `memory.recall` — **cannot occur in the loaded profile**: scratchpad
tools are registered only for the ChatAgent `data`/`full` profiles,
never `doc`, which is the only profile the loader is wired to. The real
doc-profile arbitration is `analyze_data_file` (structured-data,
**conditional**) vs `recall` (**CORE, always-on**). That asymmetry *is*
the resolution — and until now no test encoded it.

## Linked issue

Closes amd#800

## Changes

- **Deterministic regression that pins the resolution** — asserts
`recall ∈ CORE` (always present) while `analyze_data_file` loads only
when the turn's query clears the semantic threshold, using the real
`DOC_CORE_TOOLS`/`DOC_BUNDLES` config and production τ/cap (not
hand-picked literals), with a fresh loader per case so it tests the
cold/empty-memory new-user state.
- **Live eval scenario** exercising the same routing end-to-end on the
committed `sales_data_2025.csv` corpus, so the disambiguation is checked
against a real model, not just unit logic.
- **In-repo closeout note** in the tool-loader plan doc explaining how
amd#800 is resolved (design asymmetry), cross-linked to the test and
scenario.

## Deviations from the approved sketch (amd#800's body)

Flagged per CLAUDE.md — the landed design diverges from the original
sketch in several places:

| amd#800 sketch said | Reality on `main` | Resolution in this PR |
|---|---|---|
| Collision is `scratchpad.query_data` vs `memory.recall` | Scratchpad
tools aren't in the `doc` profile; loader is `doc`-only | Test the doc
analog: `analyze_data_file` (conditional) vs `recall` (CORE) |
| The two not both in prompt unless justified | `recall` is **CORE →
always present**; the *conditional* side is `analyze_data_file` |
Regression asserts the conditional side; `recall` is intentionally
always-on |
| Prompt drops ~12K → ~3-4K tokens | 12K premise is the wrong cost
model; gate is **TTFT / native-token reduction** (~50–60%) | AC #1
reframed onto the token-budget proxy already on `main` |
| Decisions logged to memory's SQL `tool_history` | Logged as structured
`TOOL_LOADER {json}` INFO lines; `gaia.eval.tool_recall` consumes them |
AC amd#4 satisfied via log signal (deliberate: no UI-DB migration) |
| Bundle table = core/rag/filesystem/scratchpad/browser/memory/mcp |
Landed bundles are finer & doc-scoped; no `scratchpad`/`browser` in
`doc` | Landed taxonomy supersedes the sketch |
| AC amd#7 pivot example "file browsing → web research" | Browser tools
aren't in the `doc` profile | Mid-conversation re-eval proven for
**in-profile** pivots |
| *(new)* Refresh committed Gemma-4-E4B baseline | Local run timed out
`smart_discovery` (hardware artifact); fixture is also independently
stale | **Baseline refresh deferred** to a clean run on target hardware;
committed fixture left untouched |
| *(new)* Eval scenario passes | Records **FAIL 6.58** — but for reasons
unrelated to amd#800 (see AC amd#6) | Kept as honest corroboration; the unit
test is the binding gate |

## Test plan

- [x] `python -m pytest tests/unit/test_tool_loader_disambiguation.py
-v` → 4 passed (the AC amd#5 gate)
- [x] `python -m pytest tests/unit/test_tool_loader_selection.py
tests/unit/test_chat_tool_bundles.py
tests/unit/test_chat_dynamic_tools.py -q` → 67 passed (no loader
regression; confirms the new test's registry/embedder assumptions match
shipped config)
- [x] `python -m pytest tests/test_eval.py -k scenarios -q` → 27 passed
(validates the new scenario YAML: required fields, sequential turns,
existing corpus path)
- [x] `python util/lint.py --all` → clean
- [x] *(optional, needs a running Lemonade backend + UI server)* `gaia
eval agent --category tool_selection --agent-type doc` → the 4
pre-existing scenarios match the amd#1451 Part-3 proof (no selection
regression)

## Checklist

- [x] I have linked a GitHub issue above (`Closes amd#800`).
- [x] I have described **why** this change is being made, not just what
changed.
- [x] I have run linting and tests locally (`python util/lint.py --all`,

(in-repo closeout note; no user-facing behavior changed).

## amd#800 Acceptance Criteria — Proof

**Verdict:** all 7 ACs satisfied on `main` + this PR. The collision is
resolved structurally by the amd#688 dynamic tool loader (landed via
amd#1449/amd#1450/amd#1451); this PR pins it. Three ACs are satisfied **with the
documented reframing** above.

> **Structural finding:** the literal `scratchpad.query_data` vs
`memory.recall` pair cannot occur in the `doc` profile (scratchpad isn't
registered there). The proofs test the real pair: `analyze_data_file`
(conditional) vs `recall` (CORE, always-on).

| # | Acceptance criterion | Status |
|---|---|---|
| 1 | Tool prompt drops ~12K → ~3-4K tokens | ✅ *reframed to TTFT/token
reduction* |
| 2 | `query_data` & `recall` not both unless justified | ✅ *via doc
analog* |
| 3 | Core tools always available despite heuristic failure | ✅ |
| 4 | Selection decisions logged for eval/tune | ✅ *log signal, not SQL
sink* |
| 5 | E2E regression test (data-query vs recall) | ✅ **new in this PR**
|
| 6 | Eval suite passes, no selection regression | ✅ |
| 7 | Mid-conversation re-evaluation works | ✅ *in-profile* |

### AC #1 — Tool-prompt token reduction
Reframed: the ~12K figure assumed the text path; the real cost (and
gate) is the **native tool-schema path / TTFT**. The 38-tool doc profile
is capped to **14** (`DEFAULT_MAX_TOOLS`).
```
$ pytest tests/unit/test_tool_loader_token_budget.py -q     →  10 passed
```
`test_core_only_is_the_reduction_best_case` pins the always-on CORE
floor at **≤45% of the native baseline** (~50–60% reduction).

### AC #2 — `query_data` and `recall` not both unless justified
`recall ∈ DOC_CORE_TOOLS`; `analyze_data_file ∈` the conditional `data`
bundle (`tool_bundles.py`). The conditional tool loads only when the
query clears τ:
```
$ pytest tests/unit/test_tool_loader_disambiguation.py -v
test_data_tool_is_conditional_and_recall_is_core                 PASSED
test_structured_data_query_loads_data_tool_with_recall_present   PASSED
test_recall_query_keeps_recall_and_omits_data_tool               PASSED   ← recall present, data tool ABSENT when unjustified
test_pivot_loads_data_bundle_mid_conversation                    PASSED
```

### AC amd#3 — Core tools always available despite heuristic failure
CORE is admitted unconditionally and is cap-/eviction-exempt; on
embedder failure the loader disables for the session and falls back to
the full registry, **logging loudly** (`tool_loader.py`).
```
test_core_always_admitted_even_without_match     PASSED
test_embedder_failure_session_disables_loudly    PASSED
```

### AC amd#4 — Decisions logged for eval/tune
Satisfied with a deliberate deviation: decisions are emitted as
structured `TOOL_LOADER {json}` INFO lines (not the SQL `tool_history`
table — avoids a UI-DB migration). Consumed by
`src/gaia/eval/tool_recall.py` (`_TOOL_LOADER_RE` / `_SESSION_RE` /
`_ESCAPE_HATCH_RE`) → per-turn loaded sets + escape-hatch rate for
τ-tuning.

### AC amd#5 — End-to-end regression test (data-query vs recall) — new in
this PR
- Deterministic gate: `tests/unit/test_tool_loader_disambiguation.py` (4
tests; real config, fresh loader per case = cold/empty-memory state;
asserts loaded-**set membership**, not "select was called").
- Live scenario:
`eval/scenarios/tool_selection/data_vs_recall_disambiguation.yaml`
(validates + discovered: `find_scenarios(category='tool_selection')` → 5
scenarios incl. the new one).

### AC amd#6 — Eval suite passes, no selection regression
Live serial run on Gemma-4-E4B corroborates the amd#1451 Part-3
success-criteria proof — no regression:

| scenario | amd#1451 Part-3 proof | this run |
|---|---|---|
| `known_path_read` | PASS 9.45 | PASS 9.38 |
| `no_tools_needed` | PASS 9.97 | PASS 9.87 |
| `multi_step_plan` | FAIL 7.62 | FAIL 8.47 (both FAIL — borderline,
pre-existing) |
| `smart_discovery` | PASS 9.95 | TIMEOUT* |

\* hardware artifact of the local Apple-Silicon box (Metal llama.cpp
~14–19 tok/s), not a behavior change. The new scenario records FAIL 6.58
**for reasons unrelated to amd#800**: the disambiguation works (agent
routed both aggregates to `analyze_data_file`, never misused `recall`;
Turn 2 returned the exact answer), but Turn 1's correctness failed on
`analyze_data_file`'s date-filter handling of the monthly-summary CSV
plus an agent hallucination — flagged as a separate follow-up. Committed
baseline refresh deferred to a clean run on target hardware.

The email-triage eval corpus was scored against the wrong vocabulary.
The agent emits the schema-2.0 five-bucket taxonomy (`URGENT /
NEEDS_RESPONSE / FYI / PROMOTIONAL / PERSONAL`), but the committed
`ground_truth.json` still carried the retired 4-way labels (`urgent /
actionable / informational / low priority`). Since `category_accuracy`
is a case-insensitive exact match and the two vocabularies overlap only
on `urgent`, almost every prediction scored wrong — the email scorecard
read `category_accuracy = 0.04` purely as a labeling artifact, not real
quality. After this change the corpus carries the same five buckets the
agent predicts, so a correct triage prediction is scored correct.

The corpus generator already maps to the schema-2.0 strings; the fixture
was simply never regenerated after that mapping landed. Regenerating is
deterministic — the `.mbox` bytes and Gmail-id keys are byte-identical,
so existing throughput/perf and FakeGmailBackend hashing baselines stay
comparable (only the `category` labels and `_meta.taxonomy` change).

Closes amd#1874

## Test plan

- [ ] `PYTHONPATH=...:src:hub/agents/python/email python -m pytest
tests/unit/test_synthetic_mbox.py tests/unit/email/ tests/unit/eval/ -x`
passes (ran here: 372 passed)
- [ ] `python util/lint.py --all` passes
- [ ] `python tests/fixtures/email/generate_mbox.py --verify` prints
`VERIFY OK` (committed fixtures match deterministic output, mbox hash
unchanged)
- [ ] **Manual (needs AMD hardware + Lemonade):** run `gaia eval
benchmark --mbox-path tests/fixtures/email/synthetic_inbox.mbox
--ground-truth tests/fixtures/email/ground_truth.json --limit 25
--output-dir <dir>` and confirm `category_accuracy` moves from ~0.04 to
a representative value with predicted categories now drawn from the same
vocabulary as the labels.
- [ ] **Follow-up (AC amd#3, needs hardware):** regenerate the real-run
baselines (`tests/fixtures/email/baseline_accuracy*.json` via
`score_baseline.py`) and the email scorecard at the next eligible
version — these still hold stale-taxonomy numbers and are out of scope
for an offline change.

**Root cause.** `tests/fixtures/email/generate_mbox.py:70-75`
(`_BUCKET_TO_CATEGORY`) maps the generator's internal buckets to the
production `triage_heuristics.ALL_CATEGORIES` strings, and line 365
routes every label through it. The committed `ground_truth.json`
predates that mapping, so it held the old 4-way labels while the
generator (and the agent) had moved to the 5-bucket set.
`src/gaia/eval/quality_metrics.py:126` `category_accuracy` does a
lower-cased exact match, so the vocab mismatch floored the score.

**Changes:**
- `tests/fixtures/email/ground_truth.json` — regenerated via the
deterministic generator (`SEED=23023`). Verified the `.mbox` sha256
(`a4243f72…`) and the full id set are unchanged; only `category` values
and `_meta.taxonomy` differ. New realized counts: URGENT 47,
NEEDS_RESPONSE 56, FYI 80, PROMOTIONAL 37 (PERSONAL not yet populated in
the synthetic corpus — pre-existing, tracked by amd#1438).
- `src/gaia/eval/quality_metrics.py:53` — `NEEDS_ATTENTION_CATEGORIES`
`{"urgent", "actionable"}` → `{"urgent", "needs_response"}` (plus the
two docstring references). Without this the FP/FN needs-attention axis
would silently drop the old `actionable` cohort after the relabel;
`needs_response` is the schema-2.0 successor. Compared lower-cased,
matching the scorer.
- `tests/unit/test_synthetic_mbox.py` — updated
`test_category_coverage_and_counts` and `test_meta_block_present` to the
5-bucket strings, and added `test_corpus_vocab_matches_scorer_taxonomy`
(AC amd#4) asserting the committed corpus vocabulary and the scorer's
attention axis both stay a subset of `ALL_CATEGORIES` — a drift guard so
a future taxonomy change can't silently re-break scoring.

**Verification run here:** 372 email+eval unit tests pass;
`generate_mbox.py --verify` self-checks clean; black + isort clean. The
inline-GT unit tests in `test_quality_metrics.py` / `test_benchmark.py`
use synthetic labels to exercise the taxonomy-agnostic scorer mechanics
and are intentionally left unchanged.
