fix(memory): ranked recall retrieval + a visible difference between broken and empty memory (#7185) by serrrfirat · Pull Request #7553 · nearai/ironclaw

serrrfirat · 2026-08-12T18:24:04Z

Summary

Memory recall could not match a paraphrase. Filter::Fts builds an AND over every non-stopword term of the raw user message, so a question worded even slightly differently from the saved sentence returned nothing. A fact saved as "Sarah prefers the standup meeting scheduled early on Thursday mornings" was invisible to "when does Sarah like her standup scheduled" purely because the stored text has no "like". Adds an explicit ranked retrieval mode — Filter::FtsRanked — that matches on ANY content term and orders by backend relevance (bm25() on libSQL, ts_rank over an OR tsquery on PostgreSQL, distinct-term coverage in the in-memory reference). Filter::Fts keeps its every-term semantics untouched.
A broken memory backend looked exactly like an empty memory. Lane errors were logged at debug! and returned as an empty snippet list, and the loop host cached that empty list for the whole run — so "retrieval is down" and "the user has nothing stored" were indistinguishable in test evidence and in operator diagnostics. MemoryPromptContextService now returns a typed MemoryPromptContextLoad { snippets, degradations }, and a degraded load emits one operator-visible driver note per run.
Retrieval stays best-effort and still never fails a turn; the per-run fetch cache stays, but the cached value now records that it failed instead of laundering the failure into "empty".
Layers touched: ironclaw_filesystem (new index filter variant + three backend implementations), ironclaw_memory_native (search path moves to the ranked variant), ironclaw_loop_contracts (port return type + degradation vocabulary), ironclaw_host_runtime (lane admission records failures), ironclaw_loop_host (cache shape + driver-note emit), integration harness assertions and two new group_memory scenarios.
Slice 3 (user_id unification) is deliberately NOT in this PR — see Review Follow-Through.

Validation

cargo fmt --all -- --check
cargo clippy on touched crates (ironclaw_filesystem, ironclaw_memory_native, ironclaw_loop_contracts, ironclaw_loop_host, ironclaw_host_runtime, ironclaw_integration_tests) --all-features --all-targets -- -D warnings — clean
cargo check --workspace --all-targets --all-features — clean
Relevant tests pass: see Commands run
cargo test -p <owning-crate> --features integration — the Postgres leg of the filesystem contract suite did not run locally: Docker/testcontainers is unavailable in this environment, so postgres_ranked_fts_finds_paraphrased_recall_in_relevance_order soft-skipped. It needs a CI run with Docker to be considered verified.
Manual testing: none beyond the automated suites.

Test Strategy

User behavior: a user saves a fact in one conversation and asks about it later, in their own words, in another conversation. Before this change the recall silently missed unless the question repeated the stored wording; and when memory retrieval broke outright, the user and the operator saw the same thing as "nothing stored".

Risk areas:

Model behavior (memory snippets reach the prompt)
Browser
Side effect
Persistence (filesystem index query semantics on libSQL / PostgreSQL / in-memory)
Security or permissions
External provider
Cross-component behavior (filesystem → memory-native → host runtime → loop host)

Tests added or updated:

Unit or contract:
- crates/substrates/ironclaw_filesystem/tests/db_root_filesystem_contract.rs — new shared ranked_fts_contract body with libSQL, in-memory, and Postgres legs.
- crates/kernel/ironclaw_host_runtime/tests/memory_prompt_context.rs — outage records both lanes; a partial failure records only the failing lane; a healthy empty result records nothing (new test empty_result_from_healthy_lanes_reports_no_degradation).
- crates/contracts/ironclaw_loop_contracts/tests/memory_prompt_context_service.rs — "no memory backend wired" is not a degradation.
Reborn integration:
- tests/integration/group_memory/scenario_paraphrased_prompt_recall_libsql.rs — paraphrased recall through the real composition over the shipping libSQL backend.
- tests/integration/group_memory/scenario_memory_retrieval_failure_is_visible.rs — two byte-identical turns differing only in whether the bound provider's lanes return Err(unavailable) or Ok(vec![]).
Recorded fixture: Not applicable: no model request shape or tool description changed (golden payload snapshots re-run unchanged).
Browser E2E: Not applicable: no user-visible WebUI surface changed.
Backend or runtime: the Postgres leg exists but is Docker-gated and unrun locally (stated above).
Live canary: Not applicable.

What the tests prove — both new integration scenarios were verified to fail before the fix, not merely to pass after:

With the memory-native search path reverted to Filter::Fts:
paraphrased_prompt_recall_libsql: no captured system prompt containing "Thursday mornings"
With the driver-note emit disabled:
memory_retrieval_failure_is_visible: no driver note reporting degraded memory retrieval; saw []

The filesystem contract body opens by asserting the AND filter finds nothing for the same query, so it cannot pass under the old semantics either. The paraphrase scenario writes to a NON-standing document (notes/standup.md) precisely so the always-on MEMORY.md lane from #7365 cannot satisfy it, and the observability scenario pairs the positive assertion with a healthy-but-empty arm so the note cannot be unconditional noise.

Security Impact

No change to permissions, secrets, network egress, or sandbox policy. Two things worth a reviewer's eye:

Query-language safety. Both new SQL paths keep untrusted caller text out of the query grammar. libSQL quotes each normalized term individually and writes the OR joiner itself, so only operator tokens this code emits reach FTS5 MATCH. PostgreSQL binds the joined expression as a parameter to to_tsquery. The terms come from the existing shared plain_fts_terms parser, which returns Unicode-alphanumeric strings only. Splicing of the FTS table name (libSQL) and the JSON key (PostgreSQL) follows the existing IndexKey/IndexName validation ([A-Za-z_][A-Za-z0-9_]*) already relied on by the predicate translator.
Degradation labels are a closed vocabulary. A MemoryRetrievalDegradation carries only lane (short_term/long_term) and kind (input/unavailable). No backend message, query text, path, or identifier reaches the driver-note summary.

Broadening a memory search from AND to OR returns MORE rows, so it is worth stating explicitly: scoping is unchanged. The ranked query keeps the same prefix constraint as the predicate path, and the host's ExpectedScope cross-scope drop filter is untouched. The existing cross-user isolation scenario in scenario_proactive_prompt_recall_libsql (which seeds a second user's document with word-for-word the same content) still passes.

Reborn Trust-Boundary Checklist

Public policy/evidence/trust-bearing types: MemoryPromptContextLoad / MemoryRetrievalDegradation are plain data with public constructors, deliberately — they describe a degradation, they do not grant anything. No trust or authority is derived from them.
Untrusted content enters prompts only through an envelope/escaping primitive: unchanged. This PR does not touch sanitize_snippet_text, the untrusted-memory envelope, redaction, or the byte budgets — only which records the backend returns and how a failure is reported.
Hashes declare purpose: N/A — no hashing changed.
New/changed variants: downstream match sites audited. Filter is a public enum with a new variant, so every exhaustive match was updated: crates/substrates/ironclaw_filesystem/src/index.rs (collect_equality_values), src/in_memory.rs (filter_matches), src/libsql.rs (translate_filter, collect_fts_keys), src/postgres.rs (translate_filter). Command: rg -n "Filter::(All|Fts|VectorNearest)" crates/.
Filter::Fts consumers audited (the reason this is a new variant rather than a semantics flip): the ONLY production consumer is crates/extensions/packages/memory-native/src/repo/filesystem.rs::search_documents, which this PR moves to the ranked variant. Every other reference is inside ironclaw_filesystem itself — the three backends' translators and tests/db_root_filesystem_contract.rs. Command: rg -n "Filter::Fts" crates/ tests/. No other subsystem's search semantics change.
Security/durability serde(default) fields: N/A — Filter gains a variant, and it is only ever constructed in-process; no persisted Filter payloads exist.
Queues/maps/buffers/counters bounded: FtsRanked.limit is clamped to Page::MAX_LIMIT before binding on both SQL backends and truncates the ranked vector in the reference backend. The degradation vector is bounded by the number of lanes (2). The driver note is emitted at most once per run via a dedicated OnceCell.
Driver/operator-visible errors have stable class semantics: MemoryRetrievalFailureKind is exactly that closed class (input / unavailable), mapped from MemoryServiceErrorKind.
Sandbox/native/host names accurately describe trust boundary: unchanged.

Database Impact

No migrations and no schema change. Both SQL backends gain a new query shape over existing tables and indexes:

libSQL joins the already-declared FTS5 shadow table and orders by bm25(). It reuses the existing discover_fts_tables_for_filter resolution, so an index declared on an ancestor prefix still serves child-path queries. No FTS declaration or trigger behavior changed.
PostgreSQL adds a to_tsquery/ts_rank query against the same to_tsvector('english', indexed->>'<key>') expression the existing GIN index and predicate path use, so the planner can still use that index.
In-memory gets a matching scored scan so the three backends stay behaviorally consistent under the shared contract suite.

Parity is covered by the shared ranked_fts_contract body — but the Postgres leg is Docker-gated and did not run locally.

Blast Radius

ironclaw_filesystem's public Filter enum (new variant), the memory search path, the memory prompt-context port and its two production implementations, and the loop host's per-run memory cache. The MemoryPromptContextService signature change is compile-enforced; all four implementations (production, Empty, and two test doubles) were updated.

What could break: memory search now returns more, lower-relevance rows than before for a given query. The pre-fusion limit, the host's snippet count cap, the 512 B per-snippet and 4 KiB aggregate budgets, and the cross-scope drop filter all still apply on top, so the model-visible surface stays bounded — but a query that previously returned nothing may now spend budget on a marginal hit.

Rollback Plan

Revert the two commits. They are independent: 11bbc498 (ranked retrieval) and b6a97e83 (observability) can be reverted separately. Neither writes data or changes any persisted shape, so a revert needs no migration or cleanup.

Review Follow-Through

Slice 1 satisfies the outstanding operator-diagnostics criterion on #7275 — "a retrieval/backend failure must be distinguishable from no matching memory" now holds both in the returned value (typed degradations) and in an operator-visible channel (a driver note reaching the live work summary), and the distinction is pinned in both directions at the crate tier and through the real composition at the integration tier.

On the mechanism choice, and specifically on NOT using a log level: the project REPL rule is that info!/warn! corrupt the terminal UI and background tasks must never use info!. The failure path here runs on a background prompt build, so promoting these to warn! was not available. The structural distinction is the fix; debug! remains only as the log half. The driver note reaches the live projection but is not durable — LoopHostMilestoneKind::DriverNote is deliberately not mapped to a RuntimeEvent (crates/loop/ironclaw_turn_runner/src/milestone_events.rs). If the requirement turns out to be "survives process restart", that is a follow-up needing an architecture decision about the durable event vocabulary, not a silent widening here.

Slice 3 (write / proactive-read / after-turn-record user_id unification) is reported rather than implemented — reviewer judgment wanted. What the code actually does today:

Write path: resource_scope_for_run → LoopRunContext::acting_resource_scope → the actor when the run has one, else the explicit thread owner, else the configured fallback.
Proactive read: invocation_for_context_request uses request.actor.user_id, and the loop host returns no memory at all when the run has no actor (build_memory_prompt_context_request returns None).
After-turn record: invocation_for_run uses actor.user_id, and after_turn_memory skips entirely without an actor.

So the divergence is narrower than "writes and reads land in different directories". Whenever a run has an actor, all three agree — LoopRunContext::acting_user_id documents that since the ephemeral-per-ping remodel a run's owner IS its actor, so the actor and explicit-owner rungs never disagree. The real gap is actorless runs (host/trigger-initiated with a bound creator): writes land under the owner, while proactive reads and after-turn recording do not happen at all.

Closing that gap is not a mechanical unification. It means changing MemoryPromptContextRequest.actor from a required TurnActor to an optional identity (or resolving acting_user_id at a seam that has no configured fallback user today), and it converts "no memory read" into "memory read under some other identity" on an identity boundary — with a fail-open risk if the fallback resolves to a system user. My recommendation is a separate PR that unifies on LoopRunContext::acting_user_id for all three paths, with regression tests for owner≠actor and for the project/agent axes varying between two conversations of the same user, and an explicit decision on what an actorless trigger run should read. I did not want to guess that in this PR.

Review track: C (runtime/DB)

…every term Memory recall from a conversation almost never matched. `Filter::Fts` builds an AND over every non-stopword term of the raw user message, so a question worded even slightly differently from the saved sentence returned nothing: one missing word was enough. A fact saved as "Sarah prefers the standup meeting scheduled early on Thursday mornings" was invisible to "when does Sarah like her standup scheduled" purely because the stored text has no "like". Add an explicit ranked retrieval mode rather than flipping AND to OR for everyone. `Filter::FtsRanked { key, query, limit }` matches a record carrying ANY content term and orders by backend relevance — `bm25()` on libSQL, `ts_rank` over an OR `tsquery` on PostgreSQL, and distinct-term coverage in the in-memory reference so the three stay behaviorally consistent. Like `Filter::VectorNearest` it is a top-k operation: `limit` truncates after ranking and nesting it inside And/Or is `Unsupported` on every backend, because a predicate position would discard the ordering. `Filter::Fts` keeps its every-term semantics untouched. Its only production consumer is memory-native's search path, which moves to the ranked variant; the remaining uses are the filesystem crate's own contract tests. Tests: a three-backend `ranked_fts_contract` in the filesystem contract suite (libSQL + in-memory run locally, Postgres leg is docker-gated and unrun here) that opens by asserting the AND filter finds nothing, so it cannot pass under the old semantics; and a group_memory integration scenario driving the real composition, verified to fail on the previous behavior with "no captured system prompt containing \"Thursday mornings\"". It writes to a non-standing document so the always-on MEMORY.md lane from #7365 cannot satisfy it. Part of #7185, #7275 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

…mpty one A memory backend that was down and a user with nothing relevant stored produced exactly the same thing: an empty prompt section. Every failure on the retrieval path degraded silently — the host adapter logged the lane error at `debug!` and returned an empty list, and the loop host cached that empty list in its per-run `OnceCell`, so one blip blanked memory for the whole run with no way to tell afterwards whether memory was empty or broken. Make the outcome typed instead of inferred. `MemoryPromptContextService` now returns `MemoryPromptContextLoad { snippets, degradations }`, mirroring `LoopContextBundle`'s existing shape of "successful payload plus an explicit, typed description of what was lost" (`recent_window_truncation`). A degradation names the lane (`short_term` / `long_term`) and a closed-vocabulary failure kind (`input` / `unavailable`) — never a backend message, a query, or a path. `degradations` is empty exactly when every queried lane answered, so an empty result from a healthy backend is no longer confusable with an outage. Retrieval stays best-effort and never fails a turn, and the per-run cache stays (it exists to stop a slow backend being re-hit on every model step) — but the cached value now RECORDS that it failed rather than laundering the failure into "empty". Operator visibility rides the milestone sink the context port already holds: a degraded load emits one `LoopDriverNoteKind::Context` driver note per run, which reaches the live work summary. This is the same route `publish_personal_context_admitted` uses and the same rationale as `EventSubscriptionTerminated` — a subsystem that stopped contributing must not be silently invisible. Deliberately NOT promoted to `warn!`/`info!`: those levels render in the REPL and corrupt the terminal UI, and this fires from a background prompt build. Tests: crate tier pins both directions in the host adapter (an outage records both lanes, a partial failure records only the failing one, and a healthy empty result records nothing); integration tier drives the real composition with two byte-identical turns differing only in whether the bound provider's lanes return `Err(unavailable)` or `Ok(vec![])`, verified to fail before the change with "no driver note reporting degraded memory retrieval; saw []".

📝 Walkthrough

Summary by CodeRabbit

New Features
- Improved memory search with relevance-ranked results and bounded result counts.
- Better recall for paraphrased questions and partial-term searches.
- Memory retrieval now reports when one or more retrieval paths are unavailable.
- Successful results remain available when another retrieval path fails.
- Added a single operator-visible notice per run when memory retrieval is degraded.
Bug Fixes

Walkthrough

The change adds ranked full-text memory retrieval and replaces raw snippet results with structured loads containing per-lane degradation metadata. The loop host caches this metadata and emits one degraded-retrieval driver note per run. Backend and integration tests cover ranking, recall, and failure visibility.

Changes

Memory retrieval degradation

Layer / File(s)	Summary
Structured memory load contract `crates/contracts/ironclaw_loop_contracts/src/memory_context.rs`, `crates/contracts/ironclaw_loop_contracts/src/lib.rs`, `crates/contracts/ironclaw_loop_contracts/tests/*`	Memory loading now returns `MemoryPromptContextLoad` with snippets and typed degradation records.
Lane retrieval and degradation accumulation `crates/kernel/ironclaw_host_runtime/src/memory_context.rs`, `crates/kernel/ironclaw_host_runtime/tests/*`	The runtime records normalized failures by retrieval lane while preserving successful snippets.
Per-run caching and driver-note reporting `crates/loop/ironclaw_loop_host/src/`, `crates/loop/ironclaw_loop_host/tests/`, `tests/integration/support/assertions.rs`	The loop host caches complete loads and emits one guarded degradation note per run.

Ranked full-text retrieval

Ranked filter contract and in-memory execution `crates/substrates/ironclaw_filesystem/src/index.rs`, `crates/substrates/ironclaw_filesystem/src/in_memory.rs`	`Filter::FtsRanked` supports bounded, top-level ranked any-term matching with deterministic ordering.
libSQL and PostgreSQL ranked queries `crates/substrates/ironclaw_filesystem/src/libsql.rs`, `crates/substrates/ironclaw_filesystem/src/postgres.rs`, `crates/extensions/packages/memory-native/src/repo/filesystem.rs`	The backends execute ranked searches with relevance ordering, path scoping, limits, and shared row conversion.
Cross-backend ranked search validation `crates/substrates/ironclaw_filesystem/tests/*`	Tests cover partial matches, ranking, limits, stop-word queries, and nesting rejection.

Memory integration coverage

Layer / File(s)	Summary
Recall and failure scenarios `tests/integration/group_memory/*`, `tests/integration/support/assertions.rs`	Integration scenarios cover paraphrased recall and visible retrieval failures.
Scenario coverage metadata `tests/CLAUDE.md`	The coverage map records the two additional memory scenarios and updated totals.

🟡 Low · Retry failed degradation-note publication

The once-cell is set before the spawned driver-note publish succeeds. If the milestone sink transiently returns an error, the task only logs it; every later prompt build sees the set cell and suppresses the note. The retrieval failure is then again indistinguishable to operators from an empty memory result for that run. Mark the note emitted only after a successful publish (with an in-flight guard to avoid duplicates), and add a fail-once-sink regression test.

A second instruction requiring the exact non-standing target remained in `Working…` beyond the bounded wait and was cancelled. The later recall therefore used standing memory, which bypasses the ranked-search regression seam.	BLOCKED — not executed against intended starting state
Required	Retrieval lanes return failure for one run and healthy empty results for an otherwise identical run	The same turn completes in both states	Only the failing state emits an operator-visible `memory retrieval degraded` driver note	Real retrieval-lane failure versus healthy-empty state through the live work summary	The preview exposes no safe UI control to force the intended retrieval-lane failure while holding provider, route, role, and request constant. No substitute failure was credited.	BLOCKED — not executed
Supplemental	The fact was written to standing `MEMORY.md` via the visible `write memory` tool	A new conversation asks the paraphrased question	The rendered answer recalls the schedule	Standing-memory cross-conversation recall	Rendered answer: `Based on my memory, Sarah prefers the standup meeting scheduled early on Thursday mornings.` The same answer remained visible after refresh.	PASS
Supplemental	The exact PR head is deployed	The preview state is queried against commit-scoped statuses/check runs	Railway reports success for that head	Deployment health	`railway_state=success`; preview opened and authenticated successfully.	PASS

Status derivation

Required passed: 0
Required failed against the intended contract: 0
Required blocked/not executed: 2
Overall: BLOCKED under the mandatory gate. Supplemental deployment health and standing-memory recall cannot upgrade unexecuted required cases to PASS.

Regression result and remaining risk

The exact ranked-retrieval regression was not proven in the browser preview because the live model wrote the fact to always-on standing memory instead of the non-standing indexed document used by the changed FtsRanked path. The operator-degradation distinction was also not live-tested because the preview provides no safe way to induce the required lane failure. Deterministic PR tests remain useful supplemental evidence but do not replace these required live contracts.

Unrelated streaming, upload/download, responsive, auth lifecycle, and permission recipes were skipped because this PR does not change those contracts.

Cleanup

Deleted all three conversations created by this QA run.
Attempted to remove only the test-created line from MEMORY.md. The memory write capability rejected empty replacement content with input_encode; the document contained no other entries, but the test line could not be safely cleared. Persistent-memory cleanup is therefore incomplete and the test sentence may remain in MEMORY.md.
Browser tabs finalized.

…nership Review feedback on #7553: - libSQL answered a content-term-free ranked query with `Unsupported` when the prefix had no declared FTS index, while PostgreSQL and the in-memory backend answered "empty". The answer does not depend on an index, so it must not depend on the bound backend: read the query before resolving the FTS table. Pinned in the shared `ranked_fts_contract`, which runs on all three backends. - The degraded-retrieval driver note marked itself emitted before the publish succeeded, so one transient milestone-sink error suppressed it for the rest of the run — restoring the exact ambiguity between broken and empty memory this change exists to remove. Adopt the two-step guard `publish_personal_context_admitted` already uses (in-flight flag + set-on-success). Regression test verified red against the old guard. - `Filter::Fts` and `Filter::FtsRanked` carried separate copies of the in-memory tokenizer; they must agree on what counts as a term occurrence, so share one `fts_tokens`. - `scenario_paraphrased_prompt_recall_libsql` built its own group; the group-scenario contract puts that in the binary. It keeps a dedicated libSQL group rather than joining the shared one, because scenarios 6 and 7 assert which snippets reach the prompt and a ranked top-N lane over one store would couple those assertions to sibling seed data. - Register both new scenarios in `tests/CLAUDE.md` §3.4 and update counts.

…roken and empty memory (nearai#7185) (nearai#7553) * fix(memory): rank memory retrieval by relevance instead of requiring every term Memory recall from a conversation almost never matched. `Filter::Fts` builds an AND over every non-stopword term of the raw user message, so a question worded even slightly differently from the saved sentence returned nothing: one missing word was enough. A fact saved as "Sarah prefers the standup meeting scheduled early on Thursday mornings" was invisible to "when does Sarah like her standup scheduled" purely because the stored text has no "like". Add an explicit ranked retrieval mode rather than flipping AND to OR for everyone. `Filter::FtsRanked { key, query, limit }` matches a record carrying ANY content term and orders by backend relevance — `bm25()` on libSQL, `ts_rank` over an OR `tsquery` on PostgreSQL, and distinct-term coverage in the in-memory reference so the three stay behaviorally consistent. Like `Filter::VectorNearest` it is a top-k operation: `limit` truncates after ranking and nesting it inside And/Or is `Unsupported` on every backend, because a predicate position would discard the ordering. `Filter::Fts` keeps its every-term semantics untouched. Its only production consumer is memory-native's search path, which moves to the ranked variant; the remaining uses are the filesystem crate's own contract tests. Tests: a three-backend `ranked_fts_contract` in the filesystem contract suite (libSQL + in-memory run locally, Postgres leg is docker-gated and unrun here) that opens by asserting the AND filter finds nothing, so it cannot pass under the old semantics; and a group_memory integration scenario driving the real composition, verified to fail on the previous behavior with "no captured system prompt containing \"Thursday mornings\"". It writes to a non-standing document so the always-on MEMORY.md lane from nearai#7365 cannot satisfy it. Part of nearai#7185, nearai#7275 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(memory): make a failed memory retrieval distinguishable from an empty one A memory backend that was down and a user with nothing relevant stored produced exactly the same thing: an empty prompt section. Every failure on the retrieval path degraded silently — the host adapter logged the lane error at `debug!` and returned an empty list, and the loop host cached that empty list in its per-run `OnceCell`, so one blip blanked memory for the whole run with no way to tell afterwards whether memory was empty or broken. Make the outcome typed instead of inferred. `MemoryPromptContextService` now returns `MemoryPromptContextLoad { snippets, degradations }`, mirroring `LoopContextBundle`'s existing shape of "successful payload plus an explicit, typed description of what was lost" (`recent_window_truncation`). A degradation names the lane (`short_term` / `long_term`) and a closed-vocabulary failure kind (`input` / `unavailable`) — never a backend message, a query, or a path. `degradations` is empty exactly when every queried lane answered, so an empty result from a healthy backend is no longer confusable with an outage. Retrieval stays best-effort and never fails a turn, and the per-run cache stays (it exists to stop a slow backend being re-hit on every model step) — but the cached value now RECORDS that it failed rather than laundering the failure into "empty". Operator visibility rides the milestone sink the context port already holds: a degraded load emits one `LoopDriverNoteKind::Context` driver note per run, which reaches the live work summary. This is the same route `publish_personal_context_admitted` uses and the same rationale as `EventSubscriptionTerminated` — a subsystem that stopped contributing must not be silently invisible. Deliberately NOT promoted to `warn!`/`info!`: those levels render in the REPL and corrupt the terminal UI, and this fires from a background prompt build. Tests: crate tier pins both directions in the host adapter (an outage records both lanes, a partial failure records only the failing one, and a healthy empty result records nothing); integration tier drives the real composition with two byte-identical turns differing only in whether the bound provider's lanes return `Err(unavailable)` or `Ok(vec![])`, verified to fail before the change with "no driver note reporting degraded memory retrieval; saw []". Part of nearai#7185, nearai#7275 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(memory): address review — backend parity, note retry, scenario ownership Review feedback on nearai#7553: - libSQL answered a content-term-free ranked query with `Unsupported` when the prefix had no declared FTS index, while PostgreSQL and the in-memory backend answered "empty". The answer does not depend on an index, so it must not depend on the bound backend: read the query before resolving the FTS table.

Port from nearai/ironclaw#7553 (Filter::FtsRanked): FTS5's implicit AND between terms means a paraphrased multi-word query misses a stored sentence that lacks even one of the words. When the exact-match search and the substring fallbacks all return zero rows, retry the same unicode61 FTS index with the terms OR-joined, ranked by bm25 so rows covering more terms surface first. Strictly additive: gated on a zero-result miss, so successful searches keep exact-match semantics and ordering. Queries with explicit OR/NOT, single-term queries, and CJK-routed queries are left untouched. Quoted phrases relax as whole units. Adapted for hermes-agent: implemented inside SessionSearchMixin's zero-result fallback chain (after the CJK-bigram/trigram substring retries) rather than as a separate filter variant, reusing the already- built SQL/params so all source/role/sort filters apply to the retry.
