fix(memory): learn returns on accept; time every engine call

[M3gA-Mind]

Summary

• The agent's memory tool learn action now stores with WriteOptions::accepted() instead of the default WaitFor::Visible, so a chat turn no longer waits for the hosted engine to list and rank the learning.
• The tool result says the learning is saved and searchable in recall shortly ({"id": …, "status": "saved; searchable in recall shortly"}); it keeps the receipt id.
• The host's engine guard (memory/guard.rs, which wraps every bound engine) now emits one [memory:timing] debug line per engine call: op, engine, elapsed_ms, outcome (ok or the stable error code), count. No user content. The post_turn hook log gains elapsed_ms.

Problem

• In the dev app, one memory learn call took 95 s ([memory:tool] dispatch action=learn at 20:53:18 → [memory:ops] item stored engine=tinyhumans kind="learning" at 20:54:53). The turn's three model calls took about 8 s together, and the final answer waited on the write.
• Cause: ops::learn → store_item → engine.store(item) uses tinymemory's default WaitFor::Visible. The cortex engine then polls until the write is listed (up to 30 s) and settled in ranked recall (up to 10 s), with backoff. The hosted API does not forward ?wait=indexed, so all of that is client polling. Turn writes already used WriteOptions::accepted(); learn did not.
• There were no client-side per-call timings to measure this with (tinyhumansai/backend#1405).

Solution

• No tinymemory change: MemoryEngine::store_with(item, WriteOptions::accepted()) already exists, and cortex's Accepted path skips ?wait=indexed and the visibility waits. It returns once the events are captured (a replay lookup and the write).
• ops::learn_with / ops::store_on_with take a WriteOptions. ops::learn / ops::store_on keep visible(), so every other caller behaves exactly as before. Only the agent tool passes accepted().
• A failed accepted write still comes back synchronously as a model-visible tool error (e.g. INSUFFICIENT_CREDITS). Nothing is fire-and-forget, so no error is lost.
• Timing is in the one wrapper every bound engine already goes through (engine.rs binds all three engine sources through ScrubbingEngine::wrap). That covers ops, the pre/post-turn hooks (AgentMemory), Brain, imports and source syncs without per-call-site code.

Deliberately left on WaitFor::Visible (they need read-after-write and none blocks an openhuman chat turn):

• memory_learn RPC (Settings → Learnings). Note: the MCP server exposes this same RPC (mcp/server/tools/specs.rs:165), so an external MCP client calling memory_learn still waits the full Visible time.
• Flow memory: flows::remember_keyed (the flow_memory_remember tool and tinyflows remember nodes). These run only inside trusted Workflow runs, and a later run reads its own keys.
• store_item / store_on callers: flow run digests, source syncs (memory/sources/sync.rs), and Composio record stores.
• Bulk store_many: v1 import and conversation backfill (Settings / background).
• Already Accepted before this PR: pre_turn/post_turn turn logs (spawned; pre_turn is capped by pre_turn_timeout_ms) and Brain ingest.

Submission Checklist

• Tests added or updated (happy path + at least one failure / edge case): learn_returns_on_accept_and_says_recall_may_lag (records the WaitFor the engine receives: [Accepted] for the tool, Visible for RPC learn), a_failed_learn_is_reported_to_the_model (out-of-credits engine → tool error with the code), a_timed_call_reports_ok_or_the_error_code.
• Diff coverage ≥ 80%: 100% (73 changed lines, 0 missing) per CI Fast diff-cover at 6b2759a.
• Coverage matrix updated: N/A, behaviour-only change.
• All affected feature IDs listed under ## Related: N/A, no matrix row changes.
• No new external network dependencies introduced.
• Manual smoke checklist: N/A, not a release-cut surface.
• Linked issue closed via Closes #NNN: N/A, no openhuman issue tracks exactly this; references below.

Impact

• Desktop/CLI core only. A chat turn that learns something no longer waits on hosted indexing; the write's cost is one accepted round trip.
• A learning may be missing from recall for a short while after the tool returns. The tool result tells the model so.
• Logs: one extra debug line per memory engine call. It carries no item text, questions or ids, only the op, engine id, timing, outcome code and a count.

• Closes: N/A
• Follow-up PR(s)/TODOs: whether the MCP memory_learn path should also accept-and-return is a maintainer call.

Summary by CodeRabbit

• New Features
  • Memory learning through agent tools now returns the saved item’s ID and confirms it will be searchable shortly, without waiting for a readback before responding.
  • Newly learned items become available in memory lists shortly after acceptance. Learning through the RPC interface continues to wait for the item to be visible before returning.
  • Memory learning supports configurable write visibility, allowing different learning flows to return at the appropriate point.

Tiny Sweeper review

Tiny Sweeper reviewed this change across 6 lane(s) and found 0 active actionable finding(s). All lanes report the change looks safe to merge; the e2e lane is waiting on end-to-end jobs (`Rust E2E (mock backend)`, `Build Playwright E2E Artifact`, `E2E (Playwright / web lane)`, `Desktop E2E (full suite, 3 OS)`). Review lanes noted that code retrieval was unavailable, so they saw the diff alone, and memory retrieval was also unavailable. The change makes the agent's `learn` tool return once the write is accepted instead of waiting for indexing, keeps the RPC path reading its own write back, and adds per-call timing debug logging across the scrubbing engine wrapper and the post-turn hook.

What changed

No supported behavioral explanation was produced.

Features

• Added — Per-call timing instrumentation on the scrubbing engine wrapper: Every engine call through the wrapper now emits one `[memory:timing]` debug line with the op, engine id, elapsed_ms, outcome (`ok` or the stable error code), and a result count, never user content, referenced against backend issue tinyhumansai/backend#1405. Reads still pass through untouched, so behavior is unchanged apart from the logging. Health calls get a specialized outcome mapping to `ok`, `degraded`, or `down`, and `store_with` logs `store_accepted` vs `store` depending on the `WaitFor` option. (crates/openhuman-core/src/memory/guard.rs#impl MemoryEngine for ScrubbingEngine {)
• Modified — Agent learn returns on accept with a lag notice: The agent's `learn` action now stores via `ops::learn_with` with `WriteOptions::accepted()` so a turn never waits on the engine indexing the learning, which the code comments say can take minutes on a hosted engine. The tool result now includes a `status` field using the new `LEARN_STATUS` constant (`saved; searchable in recall shortly`) alongside the id, telling the model recall may not find the learning immediately. The event bus publishing of `DomainEvent::MemoryStored` is preserved. (crates/openhuman-core/src/memory/tools.rs#impl CallFacts {, crates/openhuman-core/src/memory/tools.rs#pub async fn run_action(config: &Config, args: &Value, facts: &CallFacts) -> Too)
• Added — WriteOptions-parameterized store and learn paths in ops: `learn` is split into a visible-waiting wrapper over a new `learn_with` that takes `WriteOptions`, and `store_on` similarly gains a `store_on_with` variant that calls `bound.engine.store_with`; the ops debug log now includes the `wait` option. The original `learn` path still uses `WriteOptions::visible()`, so RPC behavior keeps read-after-write semantics. The bound engine still scrubs stored items via the guard. (crates/openhuman-core/src/memory/ops.rs#pub async fn store_item(config: &Config, item: StoreItem) -> MemoryResult<StoreR, crates/openhuman-core/src/memory/ops.rs#fn merge_meta(meta: &mut MemoryMeta, host: MemoryMeta) {)
• Internal refactor — Post-turn hook timing added to logs: The post-turn hook now measures elapsed time for the `memory.post_turn` call and includes `elapsed_ms` on both the success debug log and the failure warn log, improving observability of reply-logging latency without changing control flow. (crates/openhuman-core/src/memory/lifecycle/hooks.rs#pub async fn post_turn(config: &Config, identity: &ResolvedIdentity, input: Post)

Merge Risk: ⚪ Minimal · up to 414de

Agent learning can return after acceptance while recall catches up, and RPC learning retains visibility-waiting behavior. No actionable merge-blocking issue is established in the reviewed changes.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 414de

Learning now confirms acceptance before it becomes searchable. Existing protections remain in the inspected paths, but durability and recovery after acceptance could not be verified.

No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The changed exposure is the existing agent learning write and its completion signals. Host-selected learning namespaces remain authoritative; the inspected comparison does not establish greater cross-agent write authority. Provider-side account isolation was not independently verified.

Trust Boundaries and Controls

• observed — The accepted-write path retains the existing host identity and privacy boundaries: caller metadata is cleared, host namespace overrides metadata, and the guard scrubs the item before forwarding the requested wait option. No scrubbing bypass was introduced in this path.

Resilience and Maintainability Implications

• observed — The previously inspected in-repository MemoryStored subscriber projects activity metadata and does not fetch the new item, providing counterevidence to an immediate-read dependency. Out-of-repository consumers and provider failures after acceptance remain outside verified coverage.

Hardening Proposals

• proposed — Confirm the provider’s durable-acceptance, retry deduplication, interruption recovery and deletion-ordering guarantees, and document that MemoryStored does not promise immediate searchability before adding consumers that depend on that interpretation.

Test tool completion while indexing is delayed.

WaitRecorder::store_with records options.wait but delegates to inner.store(item). The new test checks the requested option, not whether the tool returns before indexing completes. Existing learn-and-recall tests do not delay indexing. Add a gated-indexing test that checks the tool returns before visibility is released. Keep the Accepted option assertion separate.

[M3gA-Mind]

CodeRabbit nitpick (tools_tests.rs 468-469, gated-indexing test): skipped. Returning before visibility under WaitFor::Accepted is the engine's contract, and tinymemory's conformance suite (conformance/suite/lifecycle.rs store_with) and the cortex engine own it. A gate in a fake engine here would only test the fake. openhuman's responsibility is to request Accepted from the agent tool, and learn_returns_on_accept_and_says_recall_may_lag pins that. It was revert-checked: restoring visible() fails it with left: [Visible] right: [Accepted].
