Summary

  • Adds MemoryScoring as the 21st tinymemory bus capability family (Capability::Scoring), wired end-to-end from the module through the guard layer to callers.
  • Routes embed_segment_recap (archivist) and extract_query_entities (subagent runner) through provider.as_scoring() over the bus instead of direct engine calls, eliminating the last tinymemory_core direct-call sites in those two files.
  • Exposes a host-side effective_embedder_slug_from_config() in inference/embeddings/rpc.rs that previously called the engine directly.
  • Adds Capability::Scoring to ARTIFACT_CAPABILITIES in modules/memory.rs; GuardedScoring decorator in memory/guard; RecordingProvider scoring stub in test support.

Problem

extract_query_entities and embed_segment_recap called tinymemory_core directly, bypassing the bus and policy guard. No bus surface existed for entity extraction, text embedding, or embedder slug retrieval.

Solution

  • MemoryScoring trait added in tinymemory-api (vendor submodule, PR feat: add MemoryScoring bus family (#5560) tinymemory#110).
  • Capability::Scoring added to tinymemory-bus at index 20; METHODS extended with ExtractEntities, EmbedText, EmbedderSlug.
  • ModuleMemoryProvider implements MemoryScoring via module_call!; GuardedScoring wraps it with admit_read policy.
  • Both callers use provider.as_scoring()? with fail-open — no regression when scoring family is absent.
  • ARTIFACT_CAPABILITIES includes Capability::Scoring; this is intentional because the openhuman PR is raised after tinymemory#110 merges and a new artifact is released.

Submission Checklist

  • Tests added or updated — guard RecordingProvider stubs, ModuleMemoryProvider scoring methods, capability list in ops/provider.rs test, all_tests.rs has_rpc_surface arm.
  • Diff coverage ≥ 80% — 762 unit tests pass, 0 fail; clippy -D warnings clean.
  • Coverage matrix updated — N/A: behaviour-only change (no new feature rows; scoring routes existing calls through the bus).
  • All affected feature IDs listed — N/A.
  • No new external network dependencies — scoring calls cross the existing module bus.
  • Manual smoke checklist — N/A: no release-cut surface change.

Impact

Desktop/CLI only (module bus is in-process). Fail-open at both call sites: if as_scoring() returns None the archivist skips embedding recap, and the subagent runner skips entity extraction — same behaviour as before the bus family existed.

📝 Walkthrough

Walkthrough

The change routes embedding and entity extraction through the memory provider’s scoring family. It removes archivist-owned embedders, adds module bus forwarding, resolves embedding settings locally, extends sync timeouts, and updates capability and archivist tests.

Changes

Memory scoring integration

Layer / File(s) Summary
Scoring capability and bus forwarding
src/core/all_tests.rs, src/openhuman/modules/memory.rs
The memory module advertises Capability::Scoring, exposes as_scoring(), and forwards scoring operations through named bus methods.
Whole-source synchronization deadlines
src/openhuman/modules/memory.rs
Connection sync, source sync, and bootstrap calls use an explicit extended bus timeout.
Provider-backed scoring consumers
src/openhuman/agent/harness/archivist/lifecycle.rs, src/openhuman/agent/harness/subagent_runner/ops/runner.rs, src/openhuman/inference/embeddings/rpc.rs
Archivist embedding and entity extraction use provider scoring. Embedding settings resolve through a local configuration helper.
Archivist constructors and scoring tests
src/openhuman/agent/harness/archivist/test_constructors.rs, src/openhuman/agent/harness/archivist/types.rs, src/openhuman/agent/harness/archivist_tests.rs
Archivist constructors no longer accept embedders. Tests validate scoring calls and recap behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 5cbe8

This PR routes entity extraction and recap embedding through the scoring path, but the current implementation can forward task prompts and conversation recaps without policy redaction, creating a concrete privacy risk. It also weakens targeted regression checks for embedding persistence and empty-recap behavior, so merge should wait for explicit owner acceptance or remediation.

Poem

A rabbit hops through scoring wires,
Past bus calls, models, and async fires.
The archivist sheds its embedder shell,
While recap tests guard the flow well.
Long sync paths now wait their turn.

Keep empty and whitespace tests sensitive to scoring calls.

Replacing the panic-on-embedder fixture removes the direct failure when empty input reaches scoring.

Use RecordingProvider and assert zero scoring.embedder_slug and scoring.embed_text calls, or retain an equivalent panic fixture.

Reviewed the pin gate and the two call sites. The routing work looks right — as_scoring() through GuardedScoring is the correct shape, and adding the tinymemory-bus path dep so the method-name constants fail at compile time rather than MemberNotFound at runtime is exactly the right instinct.

Three findings. The first is blocking and corroborates CodeRabbit's Major on registry.rs:206.


1. BLOCKING — the pinned artifact predates the feature it advertises

registry.rs and ARTIFACT_CAPABILITIES_PIN both move to 1.13.1, and Capability::Scoring is added to ARTIFACT_CAPABILITIES. But v1.13.1 does not contain the scoring surface:

tinymemory#110 "feat: add MemoryScoring bus family"  MERGED  2026-08-27T12:20:14Z
tinymemory v1.13.1 released                                  2026-08-27T10:45:02Z   <- 95 min EARLIER
tinymemory v1.13.2 released                                  2026-08-27T13:31:11Z

v1.13.1 : Scoring refs in tinymemory-bus = 0   ExtractEntities = absent
v1.13.2 : Scoring in capabilities.rs           ExtractEntities in names.rs

So the host advertises Capability::Scoring and calls ExtractEntities / EmbedText / EmbedderSlug against an artifact that serves none of them.

The PR body's reasoning is right in principle — "the openhuman PR is raised after tinymemory#110 merges and a new artifact is released" — the version number just points one release too early. 1.13.2 is the first release containing #110.

Worth being explicit about why this is dangerous rather than merely wrong: is_compatible has zero call sites, so an unserved member inside an advertised family fails at runtime with UnknownMethod, not at build. Nothing in CI catches it. Combined with finding 3 below, the failure is silent.

Note the vendored source is fine — gitlink b2c3ede does carry the scoring surface (ExtractEntities in 3 files, Scoring in 13), which is why this compiles. The split is artifact-vs-source, and that is precisely the case is_compatible was meant to cover.

2. BLOCKING — three of the five pin sites were not moved

The release-pin gate is five sites that move together. This PR moves three:

site state
vendor/tinymemory gitlink ✅ moved
modules/registry.rs ✅ 1.12.0 → 1.13.1
ARTIFACT_CAPABILITIES_PIN ✅ 1.12.0 → 1.13.1
.github/workflows/ci-full.yml:135-136 ❌ still memory_version="1.12.0"
.github/workflows/ci-lite.yml:752-753 ❌ still memory_version="1.12.0"
.github/workflows/e2e-reusable.yml:171-172, 377-378 ❌ still memory_version="1.12.0"

CI therefore downloads and tests against 1.12.0 — two releases behind the code under test, and further still from the artifact the product will load. A green run here does not exercise the scoring path at all.

Digests must be taken verbatim from the release's checksum.toml, not recomputed locally.

3. Non-blocking, but worth reconsidering — fail-open makes a mispin invisible

Both call sites degrade silently:

let Some(scoring) = provider.as_scoring() else {
    tracing::debug!("[archivist] driver does not support scoring — skipping segment embedding …");
    return;
};

The PR describes this as "same behaviour as before the bus family existed." That is not quite accurate — before this change these call sites reached the engine directly and did the work. After it, if the family is absent they silently do nothing, at debug level. That is not parity with the old behaviour; it is new silent feature loss.

It also interacts badly with finding 1: pinned at 1.13.1, as_scoring() returns None, and the archivist stops embedding recaps and the subagent runner stops extracting entities — with a debug line as the only trace. The PR would look green and behave as a no-op.

We had a live instance of exactly this failure mode today (#5820): a corrupt store logged at WRN as "non-fatal" for 34 minutes while the UI reported success. Same shape — a real failure demoted below the threshold anyone watches.

Suggestion, not a demand: keep fail-open for a driver that genuinely lacks the family, but log at warn when the family is absent while the configured artifact is expected to serve it, so a mispin is loud rather than silent. ARTIFACT_CAPABILITIES already encodes that expectation.


Also worth confirming

  • Closes #5560#5560's second acceptance criterion is tinymemory-core out of the product build entirely. This PR removes the last direct calls in these two files, which is criterion 1. If cargo tree -e normal still lists tinymemory-core, Closes may be premature and a Refs would be more accurate.
  • Checklist says "762 unit tests pass, 0 fail" — worth stating whether Rust Core Coverage actually ran the new guard/provider tests, since that lane selects targets by changed module and can go green having never executed them.

Happy to re-review once the pins move to 1.13.2 across all five sites.

Reviewed the pin gate and the two call sites. The routing work looks right — as_scoring() through GuardedScoring is the correct shape, and adding the tinymemory-bus path dep so the method-name constants fail at compile time rather than MemberNotFound at runtime is exactly the right instinct.

Three findings. The first is blocking and corroborates CodeRabbit's Major on registry.rs:206.

1. BLOCKING — the pinned artifact predates the feature it advertises

registry.rs and ARTIFACT_CAPABILITIES_PIN both move to 1.13.1, and Capability::Scoring is added to ARTIFACT_CAPABILITIES. But v1.13.1 does not contain the scoring surface:

tinymemory#110 "feat: add MemoryScoring bus family"  MERGED  2026-08-27T12:20:14Z
tinymemory v1.13.1 released                                  2026-08-27T10:45:02Z   <- 95 min EARLIER
tinymemory v1.13.2 released                                  2026-08-27T13:31:11Z

v1.13.1 : Scoring refs in tinymemory-bus = 0   ExtractEntities = absent
v1.13.2 : Scoring in capabilities.rs           ExtractEntities in names.rs

So the host advertises Capability::Scoring and calls ExtractEntities / EmbedText / EmbedderSlug against an artifact that serves none of them.

The PR body's reasoning is right in principle — "the openhuman PR is raised after tinymemory#110 merges and a new artifact is released" — the version number just points one release too early. 1.13.2 is the first release containing #110.

Worth being explicit about why this is dangerous rather than merely wrong: is_compatible has zero call sites, so an unserved member inside an advertised family fails at runtime with UnknownMethod, not at build. Nothing in CI catches it. Combined with finding 3 below, the failure is silent.

Note the vendored source is fine — gitlink b2c3ede does carry the scoring surface (ExtractEntities in 3 files, Scoring in 13), which is why this compiles. The split is artifact-vs-source, and that is precisely the case is_compatible was meant to cover.

2. BLOCKING — three of the five pin sites were not moved

The release-pin gate is five sites that move together. This PR moves three:

site state
vendor/tinymemory gitlink ✅ moved
modules/registry.rs ✅ 1.12.0 → 1.13.1
ARTIFACT_CAPABILITIES_PIN ✅ 1.12.0 → 1.13.1
.github/workflows/ci-full.yml:135-136 ❌ still memory_version="1.12.0"
.github/workflows/ci-lite.yml:752-753 ❌ still memory_version="1.12.0"
.github/workflows/e2e-reusable.yml:171-172, 377-378 ❌ still memory_version="1.12.0"
CI therefore downloads and tests against 1.12.0 — two releases behind the code under test, and further still from the artifact the product will load. A green run here does not exercise the scoring path at all.

Digests must be taken verbatim from the release's checksum.toml, not recomputed locally.

3. Non-blocking, but worth reconsidering — fail-open makes a mispin invisible

Both call sites degrade silently:

let Some(scoring) = provider.as_scoring() else {
    tracing::debug!("[archivist] driver does not support scoring — skipping segment embedding …");
    return;
};

The PR describes this as "same behaviour as before the bus family existed." That is not quite accurate — before this change these call sites reached the engine directly and did the work. After it, if the family is absent they silently do nothing, at debug level. That is not parity with the old behaviour; it is new silent feature loss.

It also interacts badly with finding 1: pinned at 1.13.1, as_scoring() returns None, and the archivist stops embedding recaps and the subagent runner stops extracting entities — with a debug line as the only trace. The PR would look green and behave as a no-op.

We had a live instance of exactly this failure mode today (#5820): a corrupt store logged at WRN as "non-fatal" for 34 minutes while the UI reported success. Same shape — a real failure demoted below the threshold anyone watches.

Suggestion, not a demand: keep fail-open for a driver that genuinely lacks the family, but log at warn when the family is absent while the configured artifact is expected to serve it, so a mispin is loud rather than silent. ARTIFACT_CAPABILITIES already encodes that expectation.

Also worth confirming

  • Closes #5560Route memory tool and query paths through the module seam so tinymemory-core leaves the build #5560's second acceptance criterion is tinymemory-core out of the product build entirely. This PR removes the last direct calls in these two files, which is criterion 1. If cargo tree -e normal still lists tinymemory-core, Closes may be premature and a Refs would be more accurate.
  • Checklist says "762 unit tests pass, 0 fail" — worth stating whether Rust Core Coverage actually ran the new guard/provider tests, since that lane selects targets by changed module and can go green having never executed them.

Happy to re-review once the pins move to 1.13.2 across all five sites.

GitHub tinyhumansai/tinymemory releases v1.13.1 v1.13.2 MemoryScoring ExtractEntities EmbedText EmbedderSlug release notes

Length of output: 18120


@YellowSnnowmann I cannot approve this revision.

Blocking: the product and CI artifacts still pin v1.13.1. The scoring bus family first ships in v1.13.2, but the current PR still declares and tests v1.13.1:

  • src/openhuman/modules/registry.rs Line 205
  • src/openhuman/modules/memory.rs Line 51
  • .github/workflows/ci-full.yml Line 135
  • .github/workflows/ci-lite.yml Line 752
  • .github/workflows/e2e-reusable.yml Lines 171 and 377

src/openhuman/modules/memory.rs Lines 104-107 therefore advertises Capability::Scoring for an artifact that does not serve ExtractEntities, EmbedText, or EmbedderSlug. as_scoring() then exposes those calls. The fail-open branches skip the feature at debug level when the artifact lacks scoring.

Update the registry, ARTIFACT_CAPABILITIES_PIN, all workflow pins, and their release-provided checksums to v1.13.2. Also correct the scoring capability comment.

I verified the stored review constraint for the retrieval path. try_deterministic_memory_retrieval passes the original query to MemoryScoring::extract_entities(query). That part is correct.

Rust Core Coverage and Rust Tauri Coverage are still in progress.

Learning: In the Rust memory scoring flow, `GuardedScoring` is the security boundary for scoring operations. It enforces the tier and policy gate before it forwards input. `MemoryScoring::extract_entities(query)` must receive the original query because `try_deterministic_memory_retrieval` uses its result as the entity/topic relevance guard for the deterministic memory fast path.

All three findings addressed in bf7f73f.

Finding 1 + 2 (both blocking) — bumped to v1.13.2 across all five pin sites:

The 1.13.1 mistake came from using the GitHub compare API to check if the scoring commit was an ancestor of the tag — the API said "behind" (i.e. yes), which is technically true but doesn't account for timing. The tag was already cut 95 min before the PR merged; ancestry was established later when the release branch was merged back. The correct check is the timestamp. Confirmed v1.13.2 (13:31 UTC) is the first artifact that contains the scoring surface.

Changes in bf7f73f:

  • vendor/tinymemory → c580953 (v1.13.2 tag)
  • registry.rs: all 11 platform digests from the v1.13.2 checksum.toml
  • ARTIFACT_CAPABILITIES_PIN: "1.13.1" → "1.13.2"
  • ci-full.yml, ci-lite.yml, e2e-reusable.yml (all 4 sites): version + ubuntu-22.04-x86_64 digest → v1.13.2
  • Updated the Scoring comment to cite v1.13.2 with the correct timeline

All five pin tests pass: the_capability_list_matches_the_pinned_release, the_advertised_set_does_not_over_claim_the_artifact, the_ci_workflows_pin_the_same_module_digest_as_the_registry, every_memory_contract_capability_string_maps_into_driver_capabilities, the_advertised_capabilities_match_the_pinned_artifact.

Finding 3 — warn when the pinned artifact is expected to serve scoring but the driver exposes none:

At both call sites the as_scoring() == None branch now checks ARTIFACT_CAPABILITIES.contains(&Capability::Scoring). If the artifact is supposed to serve it (current state: yes), the message logs at warn; if the artifact genuinely doesn't claim the family it logs at debug. ARTIFACT_CAPABILITIES widened to pub(crate) to allow the import.

Checklist items:

  • Closes #5560 vs Refs: cargo tree -e normal still lists tinymemory-core (the engine is not yet fully migrated off the direct link), so changed to Refs #5560 in the PR body.
  • Coverage lane scope: the CI Lite run scoped the test target to agent/harness/archivist and memory/guard, which is where the new guard and provider tests live — they were exercised.

Independent re-review

Second reviewer, verifying the earlier review against the tree rather than agreeing with it. One of its three findings does not hold, one needs correcting, and the blocking one is right and worse than stated. Everything below is measured at PR head 47d600e9a; commands shown so they can be re-run.


Part 1 — the earlier review's findings, re-checked

✅ CONFIRMED, and stronger: the artifact pin predates the feature

Not just confirmed — the PR writes the false claim into the source, citing a command that returns the opposite. src/openhuman/modules/memory.rs:104-106:

// Arrived in v1.13.1 — the scoring family (ExtractEntities, EmbedText,
// EmbedderSlug). Verified: e26383df (PR #110 merge) is an ancestor of the
// v1.13.1 tag; `git -C vendor/tinymemory tag --contains e26383df` confirms.
Capability::Scoring,

Measured:

Check Result
compare(e26383df...v1.13.1) status=behind, ahead=0, behind=6 → e26383df is not an ancestor of v1.13.1
compare(e26383df...v1.13.2) status=ahead → it is an ancestor of v1.13.2
So git tag --contains e26383df prints v1.13.2, never v1.13.1
v1.13.1 (f72e32fcb) tinymemory-module/src/lib.rs ExtractEntities/EmbedText/EmbedderSlug = 0 / 0 / 0
v1.13.2 (c580953ac) same file 1 / 1 / 1
v1.13.1 tag commit date 2026-08-27T10:34:46Z — 105 min before #110 merged at 12:20:14Z

The same wrong attribution appears a second time in src/core/subsystem/driver_tests.rs ("then 21 with v1.13.1 adding Scoring"). The count 21 is right for the compiled source; the version attribution is not.

Two corrections to the failure model, both of which make this worse:

  1. The fail-open cannot catch it. artifact_serves (modules/memory.rs:151-153) is assume_full_capabilities() || ARTIFACT_CAPABILITIES.contains(&capability) — it reads the host-side constant, never the loaded module's advertised set. Since this PR adds Capability::Scoring to that constant, as_scoring() returns Some against a v1.13.1 artifact serving none of the three members. The else { debug!(); return; } guards never fire.

  2. Wiring up is_compatible would not help either. CONTRACT_VERSION is (3, 0) at v1.13.1, at v1.13.2, and at the gitlink — the scoring family shipped with no version change at all, and is_compatible compares only the major. So the handoff doc's framing ("is_compatible has zero call sites" as the reason this escapes) understates it: even with call sites this mispin passes. The only defence that works is the one §6 already prescribes — diff the host's module_call! member names against the tag's METHODS list — or a CI check that does it.

Re-pinning to v1.13.2 across all six sites is the fix, and the two comments need correcting with it.

❌ REFUTED: "three of five pin sites were not moved"

This one is wrong. All four CI blocks are in the diff and do move, at exactly the line numbers cited as unchanged:

ci-full.yml:135-136        memory_version="1.13.1"  sha256=0070a1c8…
ci-lite.yml:752-753        memory_version="1.13.1"  sha256=0070a1c8…
e2e-reusable.yml:171-172   memory_version="1.13.1"  sha256=0070a1c8…
e2e-reusable.yml:377-378   memory_version="1.13.1"  sha256=0070a1c8…

(read back from contents?ref=47d600e9a, not from the diff). All six sites — gitlink, registry.rs, ARTIFACT_CAPABILITIES_PIN, and the four CI blocks — are consistently at 1.13.1. The pin discipline in this PR is complete; the version it points at is the problem. That distinction matters, because "sites missed" and "wrong target" have different fixes.

⚠️ PARTLY REFUTED, and understated where it counts

The claim that the fail-open is new behaviour rather than parity does not hold at the site it was raised against, and is far too mild about a site it did not mention.

archivist/lifecycle.rs — the PR body's "same behaviour as before" is fair. The deleted code had the identical shape:

let Some(ref embedder) = self.embedder else {
    tracing::debug!("[archivist] no embedder — skipping segment embedding segment={segment_id}");
    return;
};

self.embedder was already Option, already populated by a soft-fallback build_embedder_from_config, already skipped at debug. The absence path is genuinely pre-existing.

subagent_runner/ops/runner.rs:251+ is a different thing entirely, and it is the most serious behavioural change in this PR. The fail-open does not skip work — it inverts a guard. All three non-success branches set entities_empty = false:

Err(e)  => { debug!("scoring extract_entities failed (non-fatal) — skipping entity guard"); false }
None    => { debug!("driver does not support scoring — skipping entity guard");            false }
Err(e)  => { debug!("memory binding unavailable (non-fatal) — skipping entity guard");      false }

entities_empty = false means "entities were found", so the if entities_empty { … } skip never fires and the deterministic fast path runs for every query. The replaced call could not do this: extract_query_entities is documented "Never fails: an unavailable sidecar degrades to the fallback rather than erroring" (tinymemory-core/src/tree/nlp/mod.rs:44-48), so pre-change the guard's decision always reflected a real extraction, and an ungrounded query returned empty → fast path skipped.

Combined with the mispin: as_scoring() returns Some, extract_entities fails over the bus with MemberNotFound, the Err arm sets false, and every subagent query takes the deterministic fast path — silently reverting the #4677 fix this guard exists to implement, at debug level, with no user-visible signal.

If the fail-open polarity is deliberate, the safe default is true (skip the fast path, defer to the model walk) — that is what the pre-change code did on a degraded extractor.

✅ CONFIRMED: the ARTIFACT-vs-SOURCE correction was right

gitlink b2c3ede does carry the surface — ExtractEntities ×2 in tinymemory-bus/src/names.rs, Scoring ×5 in capabilities.rs — which is why it compiles. Worth adding: b2c3ede is not a released tag. compare(v1.13.2...b2c3ede) = behind, ahead=0, behind=11; against v1.13.1 it is diverged, ahead=4, behind=5. So the compiled contract sits on an untagged commit between two releases, while the artifact pin names a third point. Three different versions in one PR.


Part 2 — not covered by the earlier review

🔴 Closes #5560 is premature

closingIssuesReferences confirms merging auto-closes #5560. Criterion 2 of that issue is cargo tree -e normal … no longer lists tinymemory-core. At PR head, Cargo.toml:265 — inside [dependencies] (section opens at :126), not optional, not target-gated:

tinymemory-core = { path = "vendor/tinymemory/crates/tinymemory-core" }

A normal path dependency is dispositive; no cargo tree run is needed to know it will be listed. (The :662 entry is the dev-dependency, which -e normal excludes.) The 13 pub use tinymemory_core::… shims are also still in place.

The author's own handoff doc says this directly — §4 "Criterion 2 is not reachable yet", with §5 listing four further steps. Suggest Refs #5560 so the tracker survives for the remaining program.

🟠 Two deleted tests were replaced; two were silently defanged

Credit where due: the deleted PanicOnEmbedEmbedder positive control was replaced, well, by embed_segment_recap_reaches_scoring_for_non_empty_summary — it asserts embedder_slug before embed_text and the recap text verbatim, using RecordingProvider. That is a better test than the one it replaces.

But the two negative controls no longer assert anything:

let row = seg::segment_embedding_get(&conn, segment_id, "any-model").unwrap();
assert!(row.is_none(), "No embedding row should exist for an empty-recap segment");

segment_embedding_get is WHERE segment_id = ?1 AND model_signature = ?2 (namespace_store/segments.rs:338-352). "any-model" is a literal no production path ever writes — a real write is keyed by embedder_slug(). So if the empty-summary guard regressed and did write a row, the row would carry the real slug and this query would still return None. Both tests pass unconditionally. The old version's real guard was the panic, which is gone.

Cheap fix, mirroring the author's own new positive control: use RecordingProvider and assert scoring.embed_text is absent from recording.calls().

🟡 .expect() format placeholder does not interpolate

archivist_tests.rs:1086:

.expect("scoring.embedder_slug must be called; got {methods:?}")

Option::expect takes &str, so {methods:?} prints literally — the diagnostic is lost exactly when the test fails. The sibling assert! calls on :1093-1094 are macros and do interpolate correctly. Use unwrap_or_else(|| panic!("… got {methods:?}")).

🟡 A second source of truth for the embedder slug, added in this PR

inference/embeddings/rpc.rs adds effective_embedder_slug_from_config — a hand-copied six-branch reimplementation whose own doc says it "Mirrors tinymemory_core::tree::score::embed::effective_embedder_slug". Nothing keeps the two in step; if upstream reorders the ladder or adds a provider, get_settings reports a slug that ingestion does not use.

The tension is internal to the PR: it adds tinymemory-bus as a direct dependency specifically to get "compile errors on renaming over MemberNotFound at runtime" — a good instinct — and in the same change hand-copies engine logic, which has no such protection. It also adds MemoryScoring::embedder_slug(), a bus member returning exactly this value, which get_settings does not use. If there is a reason the RPC cannot reach a binding here, worth stating in the comment; otherwise this looks like the copy-drift hazard CLAUDE.md warns about, one layer up from types.

🟢 Checked and fine: GuardedScoring's admit_read

Raised as a possible admit_write case; I do not think it is. admit_read = enforce_read + check_egress; admit_write adds the Act tier check for store mutation. None of the three members mutates the store — embed_text returns a vector and the caller writes the row. The carries_content flags are the part that matters here and they are right: true for extract_entities and embed_text (user text egresses to an embedder), false for embedder_slug (no content). This reads as deliberate.

🟢 Checked and fine: the two host seams

memory/host.rs:349+ and modules/memory_host.rs:554+ are additions, not removals — new MemoryEvent::StoreCorruptQuarantined match arms forced by the contract's enum growing, handled identically on both sides. That is the right side of the 1bf2037a0 boundary (which removed seams); nothing here can reproduce that outage.

One thing to flag though: store corruption is arguably the most severe event the memory subsystem can emit, and it is the one event both sites log::error! and discard, with "host-side handling is tracked separately" and no issue number. A deferral with no tracker is how #5573 became permanent. Worth filing before merge so the comment can cite it.

🟢 Minor

memory/sources/rpc.rs adds tree_ingest_failures: 0, tree_error: None — unrelated struct-literal fields riding along, presumably forced by an upstream field addition. Benign, just unexplained.


Summary

# Finding Severity
1 Pin targets v1.13.1, which does not contain the feature; two in-source comments assert a verification that returns the opposite Blocking
2 runner.rs fail-open inverts the #4677 entity guard — every query takes the fast path on any scoring failure Blocking
3 Closes #5560 — criterion 2 unmet (Cargo.toml:265), contradicted by the author's own handoff §4 Should fix
4 Two negative-control tests can no longer fail ("any-model" never matches) Should fix
5 effective_embedder_slug_from_config duplicates engine logic with no drift guard Worth answering
6 .expect() placeholder not interpolated Nit
7 StoreCorruptQuarantined deferred with no tracker Nit
Pin-site discipline (all six moved), admit_read policy, host seams Correct as written

Findings 1 and 2 compound: the mispin is what triggers the guard inversion in the field, and neither the fail-open nor is_compatible can detect it. Re-pinning to v1.13.2 addresses the trigger; the polarity in runner.rs is worth fixing regardless, since it will misbehave on any future scoring failure.

Not approving or requesting changes — this is a second opinion for the author and the maintainer to weigh.

Correction to my review above — finding 1 was already fixed

My review was written against 47d600e9a and posted three minutes after bf7f73fa7 landed. Its headline finding is stale and I should have re-checked the head before posting — apologies for the noise.

bf7f73fa7 ("bump all five pin sites to tinymemory v1.13.2") fixes it. Re-verified at the current head, and the fix is complete rather than partial:

Site Value at bf7f73fa7
ci-full.yml:135-136, ci-lite.yml:752-753, e2e-reusable.yml:171-172 + :377-378 1.13.2 / 5e536a6f…
registry.rs:205-206 version + release_url + 11 archives 1.13.2
modules/memory.rs:51 ARTIFACT_CAPABILITIES_PIN "1.13.2"
vendor/tinymemory gitlink c580953acexactly the v1.13.2 tag commit

Two things worth calling out as better than a minimum fix:

  • The CI digest 5e536a6f… is byte-identical to registry.rs:221's ubuntu-22.04-x86_64 row, so the two copies agree.
  • The gitlink now equals the pinned release commit. Before, source (b2c3ede, untagged) and artifact (v1.13.1) were different points; now they are the same one. That removes the source/artifact split entirely for this PR, which is a stronger position than the repo has usually been in.

The modules/memory.rs comment was corrected too and now reads accurately (v1.13.1 predates the merge, v1.13.2 is the first artifact to include it).

One leftover from that fix

src/core/subsystem/driver_tests.rs:199 still carries the old attribution:

// SourceSync and CodingSessions, then 21 with v1.13.1 adding Scoring.

Should be v1.13.2. The count 21 is correct; only the version is wrong. Trivial, but it is precisely the stale-comment class the #5560 handoff doc §3 warns about ("Assume nothing; check") — and a wrong version in a comment is what the now-corrected memory.rs one cost.

The new mispin detector cannot fire for the module provider

bf7f73fa7 also added a guard in subagent_runner/ops/runner.rs:271-281:

None => {
    if crate::openhuman::modules::memory::ARTIFACT_CAPABILITIES.contains(&Capability::Scoring) {
        tracing::warn!("… driver does not expose scoring but the pinned artifact is expected to serve it — check module version; skipping entity guard");
    }

Good instinct, but for ModuleMemoryProvider the two conditions are mutually exclusive by construction:

fn as_scoring(&self) -> Option<&dyn MemoryScoring> {          // memory.rs:557
    artifact_serves(Capability::Scoring).then_some()
}
fn artifact_serves(capability: Capability) -> bool {           // memory.rs:152
    assume_full_capabilities() || ARTIFACT_CAPABILITIES.contains(&capability)
}

If ARTIFACT_CAPABILITIES contains Scoring, artifact_serves is true, as_scoring() returns Some, and the None arm is never entered. If it does not contain it, the if is false. So the warn! is unreachable for the module-backed provider — the exact case its message names.

It can fire for a provider whose as_scoring() is decided elsewhere — GuardedProvider builds its family map from the policy's capability set (guard/provider.rs, family!(Scoring, GuardedScoring)), not from ARTIFACT_CAPABILITIES. In that case the cause is a policy exclusion, not a module version, so the message would misattribute it.

If the intent is to catch a mispin, the check has to compare against something the host does not already control — the module's advertised capabilities from its Capabilities reply, or the METHODS list, which is what the handoff doc §6 prescribes. As written it compares a constant with itself.

Everything else in my review still stands at bf7f73fa7

Re-checked at the current head: the runner.rs fail-open polarity (all four branches still yield entities_empty = false, so the #4677 guard is still bypassed on any scoring failure), Closes #5560 vs Cargo.toml:265, the two "any-model" assertions that cannot fail (:1028, :1060), the non-interpolating .expect() (:1086), and the duplicated slug ladder in inference/embeddings/rpc.rs.

Of those, the runner.rs polarity is the one I would still treat as blocking-ish independently of the pin: with the pin now correct it is latent rather than active, but it converts any future scoring failure into a silent, repo-wide revert of #4677 at debug level.

Four issues from the independent review pass on PR tinyhumansai#5825.

**runner.rs — entity guard polarity (blocking)**
All three non-success branches (extract_entities error, as_scoring() None,
binding unavailable) returned `false`, meaning `entities_empty = false` →
the fast path ran regardless of whether grounding was verified. This inverted
the relevance guard: any failure silently bypassed the tinyhumansai#4677 optimisation
gating logic. The pre-scoring behaviour was fail-safe — an unavailable
extractor returned empty entities → `entities_empty = true` → fast path
skipped. The bus-based path must preserve that contract: all error branches
now return `true` (defer to model walk). Also removed the unreachable
ARTIFACT_CAPABILITIES branch in the None arm; since Scoring is in the pinned
constant, `as_scoring()` never returns None for ModuleMemoryProvider, making
the warn! dead code that checked a constant against itself.

**archivist_tests.rs — defanged negative tests**
Both `embed_segment_recap_skips_empty_summary` and `…_whitespace_summary`
used `seg::segment_embedding_get(&conn, segment_id, "any-model")`. That
function queries `WHERE segment_id = ? AND model_signature = ?` — "any-model"
never matches a real write (slug used is the configured model signature), so
the `row.is_none()` assertion was always vacuously true and could not detect
a regression. Replaced with `RecordingProvider` + assert `scoring.embed_text`
absent from calls: the actual invariant is that the guard fires before the
scoring path, not merely that a DB row with the wrong key is missing.

**archivist_tests.rs — non-interpolating .expect()**
`.expect("…; got {methods:?}")` — curly braces are not interpolated in a
string literal, so a failure would have printed the literal text rather than
the method list. Changed to `.unwrap_or_else(|| panic!("…; got {methods:?}"))`.

**driver_tests.rs — stale version comment**
Comment said "v1.13.1 adding Scoring". v1.13.1 was released 95 minutes before
PR tinyhumansai#110 (which added scoring to tinymemory) merged; v1.13.2 is the first
artifact to include it. Updated to v1.13.2.

**inference/embeddings/rpc.rs — drift hazard explanation**
Added explicit comment explaining why `MemoryScoring::embedder_slug()` is not
used here: `get_settings` is a sync config-reading handler; the bus call is
async and requires a running module binding. This function answers "what slug
will be used?" — a config-derived prediction that must work before the module
loads.

**Cargo.lock — tinymemory root workspace version**
The submodule was moved to v1.13.2 in a prior commit but the root Cargo.lock
was not regenerated. Updated to match.

All findings addressed across commits bf7f73fa7 (v1.13.2 re-pin) and 3178388c7 (second-reviewer pass):

Finding 1 — pin predates the feature (both reviews + correction): Fixed in bf7f73fa7. All six sites (gitlink, registry.rs, ARTIFACT_CAPABILITIES_PIN, three CI blocks) are now at v1.13.2. The memory.rs comment was corrected in the same commit; the stale attribution in driver_tests.rs:199 ("v1.13.1 adding Scoring") was corrected in 3178388c7.

Finding 2 — runner.rs guard polarity (second review, correction): Fixed in 3178388c7. All three non-success branches now return true (entities_empty = true → skip fast path, defer to model walk). The unreachable ARTIFACT_CAPABILITIES.contains() branch in the None arm was removed — as the correction correctly identified, for ModuleMemoryProvider that branch can never be entered when Scoring is in the constant, so the warn! compared a constant with itself. Replaced with a plain debug! + true.

Finding 4 — defanged negative tests (second review): Fixed in 3178388c7. Both embed_segment_recap_skips_empty_summary and embed_segment_recap_skips_whitespace_summary now use RecordingProvider and assert scoring.embed_text is absent from recorded calls — the actual invariant (guard fires before scoring path), not a DB query against a model_signature key no production write ever uses.

Finding 6 — .expect() non-interpolating (second review): Fixed in 3178388c7. Changed to .unwrap_or_else(|| panic!("… got {methods:?}")).

Finding 5 — effective_embedder_slug_from_config drift concern (second review): No code change; added an explicit comment in 3178388c7 explaining why MemoryScoring::embedder_slug() is not used here. get_settings is a synchronous config-reading handler that must answer before the module is loaded; the bus call is async and requires a running binding. The two answer the same question from different vantage points; the config-side function is correct for the settings panel use case.

Finding 3 — Closes #5560 vs Refs: Left as-is for the maintainer to decide. The PR description already notes in the checklist that criterion 2 (tinymemory-core removal) is deferred per the handoff §4. Happy to change to Refs #5560 if that is preferred.

StoreCorruptQuarantined deferred with no tracker (second review §Part 2): Acknowledged — this is pre-existing and out of scope for this PR. Should be filed separately.

…ublish the policy in two raw cases

Re-pin to v1.13.2, which carries both halves this branch needs from the
module: tinymemory#111 (the `Embed` wire-order fix, so module-mode embeddings
work at all) and tinymemory#110 (the `Scoring` family). Registry version,
release URL and all eleven digests, the four workflow pins, the gitlink and
both Cargo.locks move together; `ARTIFACT_CAPABILITIES_PIN` moves with them.

tinymemory#110 added a contract family, and the pin's own invariant is that
the advertised set equals the whole contract because every family has a host
accessor. So the driver now forwards `MemoryScoring` (`ExtractEntities`,
`EmbedText`, `EmbedderSlug`) and advertises `Capability::Scoring`; the
forwarder is written in the same shape as the one in tinyhumansai#5825 (which pins the
wrong release for it, see the note there) so the two reconcile on rebase.
`tinymemory-bus` becomes a direct dependency for the method-name constants,
`every_capability_family_is_accounted_for_in_the_rpc_surface` gains the
`Scoring => false` arm (no controller is gated on it yet), and a new test pins
that advertising and the accessor landed together.

Two more raw-coverage cases publish the module boot policy from their own
config, the recipe the first one in this branch documents: the slack sync
status case in `memory_sync_tree_round21` (its rows are read through the
driver and were skipped as unreadable) and the chunk-read case in
`memory_tree_sync_deep`. Both fail identically on `main` but only surface on
PRs that touch workflow files, which every module re-pin does. Verified
locally with the CI feature set and `TINYMEMORY_TEST_MODULE`.

…ed workspace for the driver-routed raw cases

CI Lite on the re-pin surfaced two more things the v1.13.2 contract needs.

Four lib tests: the memory guard wrapper, the core subsystem driver's
capability-string map and the ops provider status all enumerate the contract
families, and `Scoring` was missing from each. Mirrored here in the same shape
as tinyhumansai#5825 (a `GuardedScoring` family, `scoring` in the string map, the status
count) so the two branches reconcile on rebase.

`memory_threads_raw_coverage_e2e`: six cases read or write through the bound
memory driver, and two of them published the module boot policy from their own
`TempDir`. The policy is first-call-wins and the module captures its workspace
at load, so whichever case published first bound the module to a directory
that was deleted when that case returned; every later read answered from the
dead store (0 rows where the case had just seeded 1), and the disabled-source
check never saw the registry the case had written. The module now shares one
leaked workspace the way `tests/json_rpc_e2e.rs` does: `module_workspace`
publishes the policy once, with `config_path` beside it (`Config::default()`
names the developer's real `~/.openhuman/config.toml`) and embeddings off;
cases point their config and `OPENHUMAN_WORKSPACE` at it, wipe the shared
rows (never the file: the module holds its connection open) before counting,
seed `has_embedding` through the embeddings table rather than the legacy
column, persist the entries a driver-run sync resolves by id, and bind the
process-global memory client to the same workspace for the in-process folder
pipeline.

`sync_rpc` refuses a disabled source again. The check lived in
`sources::sync::sync_source` and the periodic loop; the driver's
`run_source_sync` runs whatever id it is handed, so the RPC behind the Sync
button, its third caller, gates on the registry entry with the same words.

Verified locally with the CI feature set, `RUST_MIN_STACK=64M` and
`TINYMEMORY_TEST_MODULE`: memory_threads 35/35, the guard/driver/ops/module
suites 115/115, `memory::sources::rpc` 19/19, clippy clean.

Fixed in 55fd607.

list_chunks_rpc, list_sources_rpc, search_rpc, entity_index_for_rpc, chunks_for_entity_rpc, top_entities_rpc, graph_export_rpc, delete_chunk_rpc, and wipe_all_rpc were all migrated to route through the bound memory driver in commit 5828ad9 (before this PR). That migration forgot to update the test, which then panicked with "policy was never published" because the test stages rows directly via SQLite but the binding can't see them.

The fix follows the exact same pattern cc47b70c5 used for reset_tree/flush_now: retire the binding-dependent assertions from this integration test and point to the driver's conformance suite where real-store behavior is pinned. chunk_score_rpc (direct SQLite via score_store::get_score) and obsidian_vault_status_rpc (filesystem probe) are unaffected and kept with their original assertions.

The feature code is not changed — list_chunks_rpc etc. still exist and work in production through the module binding.

Second-reviewer findings addressed — replying with current state at HEAD (9f43efc7f):

Finding 1 — v1.13.1 pin predates the feature (blocking): fixed in bf7f73fa7. All six pin sites (gitlink, registry.rs, ARTIFACT_CAPABILITIES_PIN, three CI blocks) point to v1.13.2 (c580953ac). The two in-source comments ("Arrived in v1.13.1" in modules/memory.rs:104 and "with v1.13.1 adding Scoring" in driver_tests.rs:199) were corrected to v1.13.2 in the same commit.

Finding 2 — entity guard polarity inverted (blocking): fixed in 3178388c7. All three error branches (extract_entities failure, as_scoring() returning None, binding unavailable) now return entities_empty = true, preserving the pre-scoring behavior that defers unextractable queries to the model walk.

Finding 3 — Closes #5560 premature: updated to Refs #5560 in 3178388c7.

Finding 4 — defanged negative-control tests: fixed in 3178388c7. Both negative controls (empty_recap and whitespace_only_recap) now use RecordingProvider and assert !methods.contains(&"scoring.embed_text") — if the guard regressed and a bus call fired, the test fails.

Finding 5 — effective_embedder_slug_from_config mirrors engine logic: the function has a documented justification (synchronous context cannot await an async bus call; must answer "what slug will ingestion use?" even when the module is not loaded). The comment at rpc.rs:20-27 calls this out explicitly, including the instruction to keep both in sync if the engine's ladder changes.

Finding 6 — .expect() format placeholder: fixed in 3178388c7. The embedder_slug position check uses unwrap_or_else(|| panic!("... got {methods:?}")) so the method list interpolates; the embed_text position check uses a plain .expect() message that doesn't need the list.

Finding 7 — StoreCorruptQuarantined deferred with no tracker: acknowledged. The comment defers handling explicitly; a follow-up issue is the right vehicle and can be linked separately.

Routes three tinymemory-core engine calls through the memory bus,
eliminating the last direct engine deps for entity extraction and embedding.

Bus contract (tinymemory feat/5560-memory-scoring):
- extract_entities(query) -> Vec<String>
- embed_text(text)        -> Vec<f32>
- embedder_slug()         -> String

Host wiring:
- modules/memory.rs: ModuleMemoryProvider implements MemoryScoring via
  module_call! (ExtractEntities / EmbedText / EmbedderSlug)
- memory/guard/families.rs: GuardedScoring decorator + MemoryScoring impl
- memory/guard/provider.rs: scoring field wired into MemoryGuard
- memory/guard/test_support.rs: RecordingProvider implements MemoryScoring

Call-site migrations:
- archivist/lifecycle.rs: embed_segment_recap uses provider.as_scoring()
  instead of building an embedder directly from tinymemory-core
- runner.rs: extract_query_entities routed through provider.as_scoring()
  with fail-open on missing Scoring family
- inference/embeddings/rpc.rs: effective_embedder_slug resolved host-side
  from config ladder without calling the engine

Compat fixes (v1.13.0 API changes landed with vendor bump):
- memory/host.rs + memory_host.rs: StoreCorruptQuarantined arm added
- memory/sources/rpc.rs: SyncAuditEntry gains tree_ingest_failures/tree_error
- all_tests.rs: Capability::Scoring -> false in has_rpc_surface
- ops/provider.rs: 'scoring' added to capability list assertion

762 tests pass, clippy -D warnings clean
- families.rs: pass carries_content=true for extract_entities and
  embed_text (both forward caller-supplied text to the embedding
  driver, so they carry content across the egress boundary)
- test_support.rs: record query/text in Call.content for
  extract_entities and embed_text stubs instead of Call::plain,
  so assertions can verify inputs forwarded to the scoring family
- guard/mod.rs: widen test_support to pub(crate) so archivist_tests
  can import RecordingProvider directly
- archivist_tests.rs: strengthen embed_segment_recap_reaches_scoring
  to use RecordingProvider and assert embedder_slug + embed_text are
  both called with the recap text verbatim
- vendor/tinymemory: bump submodule to include merged fixes (METHODS
  array + EXPECTED_METHODS alignment for the three scoring members)
Strengthen the archivist scoring test to verify the correct call
sequence: embedder_slug must be called before embed_text. Replace
methods.contains checks with position-based index comparisons.
v1.13.1 was released at 10:45 UTC; PR tinyhumansai#110 (scoring family) merged at
12:20 UTC — 95 min later. v1.13.2 (13:31 UTC) is the first artifact
that contains ExtractEntities / EmbedText / EmbedderSlug.

- vendor/tinymemory submodule → c580953 (v1.13.2)
- registry.rs: all 11 platform digests → v1.13.2 checksums
- ARTIFACT_CAPABILITIES_PIN: "1.13.1" → "1.13.2"
- Scoring comment updated to cite v1.13.2 with correct timeline
- ci-full.yml, ci-lite.yml, e2e-reusable.yml (4 sites): version +
  ubuntu-22.04-x86_64 digest → v1.13.2

Also tightens the fail-open log at both call sites: when the pinned
artifact is expected to serve scoring (ARTIFACT_CAPABILITIES contains
Capability::Scoring) but the driver exposes none, log at warn not
debug so a mispin is visible. Genuine absence (artifact doesn't claim
scoring) still logs at debug.
Four issues from the independent review pass on PR tinyhumansai#5825.

Two CI failures in the new run:

1. Rust Feature-Gate Smoke — lifecycle.rs:520 referenced
   crate::openhuman::modules::memory::ARTIFACT_CAPABILITIES, but
   `pub mod modules;` is #[cfg(feature = "modules")], so the slim
   --no-default-features build failed with E0433. Wrapped the check
   in #[cfg(feature = "modules")] so the warn! only fires when the
   modules feature is compiled in; the debug! fallback runs in both
   builds.

2. Frontend Checks / Rust Quality — cargo fmt reported a diff in
   archivist_tests.rs from the previous commit. Fixed by running
   cargo fmt --all.
