fix(memory): recall facts about the user before the turn, never claim absence unsearched - #6045
Merged

… absence unsearched
"Who is my idol and why?" answered "i don't have that one stored" while the
fact sat in the memory tree, because nothing in the turn looked: the broad
per-turn recall had been removed, the only instruction telling the model to
retrieve first was gated on `learning.enabled` (default false), and nothing
forbade asserting absence without a search.
Lane C (`memory/auto_recall/`) is a gated, bounded pre-turn recall beside the
situational-preferences lane: a lexical gate opens only for a message that owns
and asks ("my … ?", "tell me my …"), one `fast_retrieve` runs through the
session binding's guard with a limit of three, a relative score floor and a
3 s budget, and the block rides the user message, never the cached system
prompt. Switched by the existing `[subsystems.memory.hooks] auto_recall`
(`OPENHUMAN_MEMORY_HOOKS_AUTO_RECALL`), which was declared and read by nothing.
Every failure is an ordinary turn without a block.
`MemoryAccessSection` is now added whenever a retrieval tool is registered and
visible, and it forbids saying something is not stored unless a retrieval just
returned nothing. `memory_recall` no longer requires `namespace`; the default
scope is searched when it is omitted.
Lane B moves from `core_turn.rs` (743/750 lines) into `turn/recall_lanes.rs`
unchanged. `RecordingProvider::with_fast_retrieve_result` scripts the guarded
retrieval family for tests.
Closes tinyhumansai#6040
…estable Review follow-ups for the Lane C lane (tinyhumansai#6040): - A hit's scope label (`folder:profile`, `slack:#eng`) lands in the prompt next to the content, so it now gets the same one-line treatment and an 80-char cap instead of a trusted pass-through. - The boot warm-up's spawned body is a plain `warm_up_from_config` so the bind-then-warm path runs under test against whichever driver the test build binds; `spawn_at_boot` only spawns it. - Coverage matrix rows 8.4.7–8.4.9 for the lane, the warm-up and the ungated memory-access instruction.

recognize the polite “please” prefix before checking LEADS, so requests like
“Please remind me what my timezone is” are accepted as Lane C fact requests. Add
this scenario to the OPENS test cases while preserving existing question and
imperative-request behavior.
In `@src/openhuman/memory/auto_recall/mod.rs`:
- Around line 251-252: Update the truncation logic in the auto-recall block and
the hit/scope handling around line 264 so emitted strings never exceed their
configured character ceilings, including when the limit is zero. Reserve suffix
capacity before truncating, or omit the suffix when the cap cannot contain it,
and add exact-boundary tests covering zero and truncated limits.
- Line 218: Update select_hits to remove hits with non-finite scores before
ranking, then sort the remaining hits using a total ordering rather than
treating partial_cmp failures as equal. Add coverage for NaN scores appearing
both before and after valid hits, ensuring invalid hits never reach
render_block.
In `@src/openhuman/memory/tools/recall.rs`:
- Around line 118-121: Update namespace handling in MemoryRecallTool::execute so
an explicitly present null, numeric, non-string, or empty-after-trimming
namespace is rejected rather than treated as omitted or mapped to
DEFAULT_AGENT_MEMORY_NAMESPACE; only an absent field should use the default
scope. Add tests covering null and numeric namespace values.

…e, tighten the caps
Review follow-ups on the auto-recall lane:
- A hit from a source tree — email, Slack, Notion, a web page, a folder — is
third-party content whose author can write instructions. It now renders
inside the `<untrusted-source>` marker the older recall path used, with the
scope prefix as the hint; chat-tree hits stay bare, a hit with no tree at
all is wrapped (default deny).
- The gate skips politeness and filler ("please remind me…", "hey, what's
my…", "quick question, do I…") before reading the lead word.
- Non-finite scores are dropped before ranking and the sort is a total
order; a NaN can no longer sort first or slip past the relative floor.
- Character ceilings are ceilings: the truncation suffix fits inside the
per-hit, scope and `recall_max_chars` caps instead of overshooting them,
and a cap too small for the suffix yields a bare prefix.
- `memory_recall` refuses a `null` or numeric `namespace` instead of reading
it as "search the default scope".

…rs stay balanced `render_block` clipped the rendered string to `recall_max_chars`, which could cut an `<untrusted-source>` marker in half or drop a closing one and so break the boundary the marker exists to draw. The budget is now spent on whole hit lines: a hit that does not fit is left out, a cap that fits no hit yields an empty block, and a property test walks caps from zero past the full length asserting equal opening and closing marker counts.
Resolves the overlap with tinyhumansai#6046 (Lane B through DriverMemory), which landed first and touched the same turn path and test fixtures: - core_turn.rs keeps the recall_lanes call; the 5 s Lane B budget that tinyhumansai#6046 set in core_turn.rs now lives in turn/recall_lanes.rs with its rationale. - turn_tests_part_04_tests.rs stays as main has it (scripted_reply is shared as pub(super)); the Lane C turn tests move to turn_tests_part_05_tests.rs, because both blocks together would cross the 750-line layout gate. - RecordingProvider carries both the fast_retrieve result and the namespace hits/summaries; the coverage matrix and .claude/memory.md keep both entries.

Summary
## Relevant memory for this messageblock on the user message before the model answers, with no tool call.learning.enabled, and extends it with "never say something is not stored unless a retrieval you just ran returned nothing".memory_recallno longer requiresnamespace; the default scope is searched when it is omitted.[subsystems.memory.hooks] auto_recall/OPENHUMAN_MEMORY_HOOKS_AUTO_RECALL(declared before this PR, read by nothing). No new config, RPC, schema or module-contract change.Problem
With
learning.enabled = false(the default, and no Settings toggle exists), "who is my idol and why?" answered "i don't have that one stored" while the same fact was retrieved a minute earlier when the user happened to say "as per the memory ingested". Nothing in the turn looked at user facts before the model answered — the broad per-turn recall was removed for cost (core_turn.rsdocuments why) and only preferences survived — the one instruction telling the model to retrieve first was gated on the learning subsystem, and nothing forbade asserting absence unsearched. The sub-agent fast path (#4677) also skips entity-less queries, so this exact phrasing was the expensive case even when the model did decide to search. Full mechanism withfile:linein #6040.Solution
memory/auto_recall/: a lexical gate (first-person ownership and a question/request shape — zero cost on closed turns; 63-message fixture pins ≥ 90 % both ways, currently 100 %), onefast_retrievethrough the session binding's guard (scope narrowing and the recall budget apply exactly as for the memory tools), a relative score floor (retrieval scores are declared non-comparable across drivers), ≤ 3 hits × 400 chars, the guard'srecall_max_chars, and a 5 s budget after which the turn proceeds without a block. Every failure — driver without the retrieval family, retrieval error, timeout — is an ordinary turn plus one[auto_recall]log line.turn/recall_lanes.rs: Lane B moved out ofcore_turn.rsunchanged (that file was 7 lines from the 750-line gate); Lanes B and C run withtokio::join!, so a turn pays the slower lookup, not the sum.auto_recall/warm.rs+modules/boot.rs: the warm-up, spawned only when the lane is on, bounded at 60 s, failure logged at debug.memory_host.rs:elapsed_msdebug lines on theembedandextract_spacyhost callbacks, so the lookup's split is visible in the field.scoring.embed_textbut costs an embed per candidate turn — deferred until real gate logs justify it); an about-me turn pays the module's own retrieval cost (1.5–3 s warm on the desktop) before the model starts.Submission Checklist
