Recall: leave the calling thread out, and an evidence mode

[sanil-23]

Summary

Two changes to recall, measured in openhuman-benchmarks #38 (memory through OpenHuman on CortexDB):

1. exclude_thread on RecallRequest and FetchRequest. A host reading inside a conversation can leave that conversation's turns out. OpenHuman logs the user's turn before the agent's memory tool reads, so today the message being answered comes back as a memory. In Run the conformance suite against the three hosted adapters (#18 §E1) #38, the agent rejected CortexDB's correct answer to a question because its only supporting citation was the question itself.
2. RecallMode::Evidence. Recall can return the evidence it found instead of a written answer, for hosts whose own model answers. On CortexDB this skips /v1/answer entirely. In Run the conformance suite against the three hosted adapters (#18 §E1) #38 that removed recall timeouts, because the answer and verification calls had pushed recalls past OpenHuman's 15 s limit. It also removed the answer/citation mismatch, where the answer is grounded on one pack while citations come from all packs. Evidence recall was the best memory setup through OpenHuman (8½/13 against 6 for the library pack on LoCoMo conversation 0).

API or behavior changes

• ThreadWindow moves from tinymemory-tools into tinymemory-api (with whole, covers, covers_meta, validate). tinymemory_tools::recall::ThreadWindow re-exports it.

• RecallRequest gains exclude_thread: Option<ThreadWindow> and mode: RecallMode (Answer by default). FetchRequest gains exclude_thread. All are serde-defaulted and skipped at their defaults, so the wire form is unchanged. Code building these structs with a struct literal must add the fields (OpenHuman's memory::ops::recall does); the new constructors set them.

• validate() refuses a blank excluded thread id.

• Answer mode is unchanged except for the exclusion. On CortexDB the exclusion reaches fetch hits and recall citations, but not the answer text CortexDB writes from the whole pack. That is documented.

• Evidence mode on CortexDB (engine/evidence.rs) uses the same per-scope granular packs and no answer route. TinyMemory renders:

  • ## Facts: [valid_from] statement;
  • ## Beliefs;
  • ## Conversation: [YYYY-MM-DD HH:MM UTC] [role] text, merged rank by rank across packs.

  Excluded turns never appear, nor do facts supported by them or beliefs resting on those facts. Derived records carry no item metadata, so they render only for a filter that narrows by reach and kinds alone. episodes and understanding are not rendered. model is None, and citations are the conversation's items, at most limit.

• Reference engine: honours both. Evidence mode returns its matching items as lines.

• Conformance: a new excluded_thread check covers fetch (every mode) and recall citations, a turn before from_turn being kept, blank-id refusal, and evidence recall never containing an excluded turn's text. The recall check also requires evidence mode to return evidence and citations and no model.

• Holistic recall's answer sections pass the pack's window to the engine. The generic memory_recall / memory_fetch tools keep Answer and no exclusion, because ToolScope does not carry the calling thread; that is a natural follow-up.

• The exclusion is deliberately not on MetaFilter, which is also the forget and erase filter: CortexDB selects forgets server-side, where an exclusion cannot apply.

Whether this needs a minor or a major bump is the maintainers' call. It is additive on the wire and through the constructors, but breaks struct literals.

Design note: I rendered the evidence in TinyMemory rather than returning CortexDB's own context_block. That keeps the exclusion exact and the granular-only isolation intact, and it is testable on the mock. While checking this I saw a granular pack on CortexDB 0.10.4 does carry a context_block (events only), contrary to the comment in cortex/log/notes.rs. I left that comment alone here.

Validation

Commands actually run, with their outcome:

• cargo fmt --all -- --check: clean
• cargo clippy --all-targets --all-features -- -D warnings: clean
• cargo build --all-targets --all-features: ok
• cargo test --all-features: 1474 passed, 0 failed
• RUSTDOCFLAGS="-D warnings" cargo doc --no-deps --all-features: ok

Supply chain CI fails on rustls 0.23.45 (RUSTSEC-2026-0346, RUSTSEC-2026-0347), published after main's last green run. It is unrelated to this change; the fix is cargo update -p rustls (0.23.46).

Tests

• tinymemory-api query::tests:
  • ThreadWindow coverage: whole thread, other thread, no thread, turns before from_turn kept;
  • blank-thread refusal;
  • unchanged serialization at the defaults.
• cortex::engine::evidence::tests:
  • an excluded turn and the facts and beliefs derived from it left out;
  • the full render layout;
  • a metadata filter keeping derived records out;
  • deduplication and the empty case;
  • role attribution and separators.
• Conformance runs against the reference engine and both CortexDB engines (direct and hosted) on the mock. I confirmed the exclusion check fails when the reference engine's fetch exclusion is removed.
• Not covered: CortexDB's real facts / beliefs shapes are exercised by unit tests built from a pack captured from CortexDB 0.10.4, not by the mock, which has no facts layer.

Documentation

• docs/architecture/cortex-flows.md:
  • fetch step 4 and recall step 3 describe the exclusion;
  • a new "Recall in evidence mode" section.
• docs/specs/agent-memory.md: the shared ThreadWindow.

Checklist

• The change is focused on recall's read behaviour (two commits: the exclusion, then evidence mode)
• No new #[allow(...)], #[ignore], or relaxed lints
• No secrets, tokens, or .env contents in the diff or the description

Summary by CodeRabbit

• New Features
  • Fetch and recall requests can exclude results from a conversation thread, either from a specified turn onward or from the entire thread.
  • Recall can return evidence directly, without generating an answer. Evidence includes citations and may include supported facts and beliefs.
• Bug Fixes
  • Recall citations and fetched results omit excluded turns. Evidence also omits facts and beliefs derived from excluded turns.
  • Requests with a blank excluded thread ID are rejected.
• Documentation
  • Clarified that excluded turns may still influence standard recall answer text, even when omitted from citations.

Tiny Sweeper review

This pull request lets recall and fetch leave a thread's turns out of what they return, and adds an evidence recall mode that returns retrieved evidence as text instead of a synthesised answer. A shared `ThreadWindow` type now lives in `tinymemory-api`, rides as `exclude_thread` on both `RecallRequest` and `FetchRequest`, and is applied by the reference engine and by the Cortex engine on the decoded pack events; the tools crate re-exports the API type where its own copy previously lived. A new `RecallMode::Evidence` on `RecallRequest` routes Cortex recall through a new `engine/evidence.rs` renderer that never calls the answer route, with the same exclusion applied and derived facts and beliefs resting on excluded turns left out. Across the critique, security, tests, commits, and description lanes no finding was reported by any lane; the critique lane could not review three files and the description lane reported the revision's description accurate against the code. Documented limitations remain: on the Cortex answer path the exclusion reaches citations only, and a fact derived from an excluded turn the pack did not return cannot be told apart.

What changed

In `crates/tinymemory-api/src/query/mod.rs`, `ThreadWindow` is defined with `whole`, `covers`, `covers_meta`, and `validate`, `RecallMode` is added with `Answer` as default plus `is_answer` for serde skipping, and both `RecallRequest` and `FetchRequest` gain `exclude_thread` and (for recall) `mode`, defaulted in their constructors and validated as non-blank; the crate root in `crates/tinymemory-api/src/lib.rs` re-exports `RecallMode` and `ThreadWindow`. The `MemoryEngine::recall` doc in `crates/tinymemory-api/src/engine/mod.rs` is widened to cover evidence mode. The reference engine in `crates/tinymemory-api/src/conformance/reference/mod.rs` retains only hits the window does not cover for both recall and fetch, and in evidence mode returns the citation snippets as its answer with no model. The Cortex engine gains `crates/tinymemory-integrations/src/cortex/engine/evidence.rs` with `recall_evidence`, `gather`, and `render`, registered in `crates/tinymemory-integrations/src/cortex/engine/mod.rs`, and `crates/tinymemory-integrations/src/cortex/engine/recall.rs` dispatches to it when the mode is `Evidence` and passes `exclude_thread` into `ranked`, whose signature in `crates/tinymemory-integrations/src/cortex/engine/fetch.rs` now takes the optional window. `crates/tinymemory-tools/src/recall/gather.rs` forwards the window and pins `RecallMode::Answer` per section, `crates/tinymemory-tools/src/recall/types.rs` replaces its local `ThreadWindow` with a re-export of the API type, and the two read entry points in `crates/tinymemory-tools/src/tools/read/mod.rs` pass `None` and the default answer mode. Docs `docs/architecture/cortex-flows.md` and `docs/specs/agent-memory.md` describe the exclusion step, its citation-only reach on the Cortex answer path, and the new evidence-mode flow.

Features

• Added — RecallMode with an Evidence variant: `RecallRequest` gains a `mode` that defaults to `Answer` and is skipped in serialization when it is the default; `Evidence` asks the engine to return the recalled evidence as the answer text with `model` set to `None`, and `MemoryEngine::recall`'s contract is updated to describe that behaviour. (crates/tinymemory-api/src/query/mod.rs#pub struct RecallRequest {, crates/tinymemory-api/src/engine/mod.rs#pub trait MemoryEngine: Send + Sync {)
• Modified — ReferenceEngine applies the window and serves evidence mode: Recall and fetch retain only hits the window does not cover before taking the limit or applying the `refers_to` hint; in evidence mode recall returns the citation snippets joined as lines with `model: None` instead of a synthesised answer. (crates/tinymemory-api/src/conformance/reference/mod.rs#impl MemoryEngine for ReferenceEngine {)
• Modified — Recall sections forward the window and stay in answer mode: Each section recall carries the caller's window so excluded turns do not consume the section's citation budget, and it pins `RecallMode::Answer` so the tools path keeps asking for a synthesised answer. (crates/tinymemory-tools/src/recall/gather.rs#async fn answer()
• Modified — Flow and spec docs describe the exclusion and evidence mode: The Cortex flow docs record that the exclusion cannot be sent to CortexDB, is applied to decoded events at fetch and recall, and reaches citations only on the answer path, and add the evidence-mode flow with its rendering rules; the agent-memory spec records that the same `ThreadWindow` rides on both read requests. (docs/architecture/cortex-flows.md#Only `Hybrid`. Other modes fail `Error::Unsupported` before any request., docs/architecture/cortex-flows.md#Recall builds a pack, asks the answer route **once** with `use_pack_id`, docs/specs/agent-memory.md#skipped, engine }`.)

Merge Risk: 🔵 Low · up to d693a

Evidence recall can occasionally surface a derived fact from an excluded thread when the originating turn is not in the retrieved pack. This is a documented limitation, so owners should be aware of it, but it does not block merging.

Security architecture risk: 🔵 Low · up to d693a

The new read options preserve the inspected scope controls and do not grant additional authority. However, thread exclusion is not complete for derived evidence whose supporting records were not retrieved. Callers should not treat this option as a confidentiality boundary.

Retained concerns

• Low · architecture · inferred: The new Evidence mode cannot exclude all content derived from an excluded thread. It records excluded event IDs only from returned events and removes beliefs only through returned, dropped facts. If an excluded supporting event is absent from the pack, its fact and dependent belief can still be rendered. This is a documented, scope-bounded contract limitation rather than a verified authorization bypass, but it prevents treating thread exclusion as complete downstream content isolation.

Security review details

Security Blast Radius

• inferred — The identified provenance limitation affects callers opting into Cortex Evidence mode and the data reachable through their selected scopes. The inspected branch does not broaden scope selection or grant additional tool authority. A cross-tenant or cross-environment exposure was not established.

Security Findings and Attack Paths

• inferred — If enrichment derives a fact from user-controlled content in an excluded thread, and retrieval returns that fact without its supporting event, the fact can reach the caller's evidence text. A dependent belief can also survive. This identifies a potential influence path through incomplete provenance, not a verified disclosure or prompt-injection exploit.

Trust Boundaries and Controls

• observed — The ordinary recall tool confines the supplied filter before calling the engine. Cortex chooses namespace scopes before mode dispatch, and evidence gathering rechecks decoded events against the item filter. Derived records lacking item metadata are suppressed when additional metadata constraints are requested.

Resilience and Maintainability Implications

• inferred — A complete excluded event-to-fact-to-belief chain is filtered, but absence of support records is treated as permission to retain derived text. Consequently, changing retrieval budgets or server ranking can change the strength of exclusion without changing the request, creating potential control drift if callers rely on stronger isolation semantics.

Hardening Proposals

• proposed — If complete derived-content exclusion becomes a security requirement, resolve supporting records to authoritative thread metadata or omit derived records whose exclusion status cannot be established. Until then, document the option as prompt-deduplication behavior rather than confidentiality enforcement.

182-264: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Add a turn-1 item to the partial-window fixture.

The fixture stores only turn 0. Therefore, from_turn: 1 has no item to exclude. A fetch implementation that ignores from_turn can still return live_id and pass because the assertion checks only that turn 0 remains.

Add a turn-1 item and assert that the partial fetch retains turn 0 but excludes turn 1. The other partial-window test exercises HolisticRecall, not FetchRequest.

152-192: 🎯 Functional Correctness | 🔵 Trivial | ⚖️ Poor tradeoff

Keep the documented limitation unless stronger provenance lookup is required.

The leak is reachable. pack_budgets gives events and derived layers independent limits, so a pack can omit an excluded event while returning its fact. gather then sees no excluded support ID and renders the fact, along with a dependent belief.

The current pack contains only support IDs for facts. It does not provide thread metadata for an omitted event. A direct supports-to-window check therefore needs an additional event-to-thread lookup or a server-side change. Keep the documented limitation, or add that lookup if exclude_thread must cover derived records.

In `gather`, preserve the documented limitation for derived facts and beliefs
when their supporting events are omitted from the pack; do not add a direct
support-to-window check without event-to-thread provenance. Only add provenance
lookup if `exclude_thread` is required to cover derived records.
