feat(memory): port the memory engine behind the TinyMemory module

[senamakel]

Summary

• Routes the memory subsystem through the loaded TinyMemory TinyBus module instead of an in-process engine: the tinymemory_core::* re-export facade is deleted, and callers reach a guarded driver via active_memory_guard().
• Widens the memory contract by five capability families — People, Chunks, Retrieval, Profile, Episodic — taking it to 18 families and (2, 1) → (2, 2) (minor: a new family is made safe by negotiation alone).
• Removes the last raw rusqlite::Connection from the host (the archivist's), and brings its policy half home as archivist::boundary.
• Closes three split brains where the host constructed a second engine over a store the module already owns, and drops the memory handle from all_tools*, ChannelRuntimeContext, and both remaining engine-construction sites.
• Brings preferences home from the engine, with no new contract surface.
• Fixes a live contacts-gate bug: macOS address-book seeding never worked.

Problem

Memory was reachable two ways at once. The module existed and was bound, but ~100 files still imported the engine directly — and the memory/mod.rs facade re-exported ~24 engine names, so grep tinymemory_core understated the real surface by about 3×. That is not a tidiness problem: two code paths over one SQLite store is a correctness problem, and three call sites were building an entire second UnifiedMemory over the workspace the module already had open.

Underneath it were three structural blockers:

1. Four host surfaces had no wire equivalent (people, chunks, retrieval primitives, profile facets).
2. The archivist held a live SQLite connection. A connection cannot cross a bus, so while it existed the engine could never leave.
3. dedicatedMemory profiles open a store at memory-<id>, and the module served one store per process — module_provider(workspace_dir) discarded its argument entirely.

Solution

Delete the facade first. With it gone, grep tinymemory_core is the inventory, and every subsequent conversion is measurable. That single change is what made the rest of the work honest.

The four families mirror the engine surfaces they replace. Guard decorators enforce policy; scoped methods take scope explicitly, because the engine resolves it from a task-local that belongs to the host's task and does not exist across a bus — inferring it would read as absent, and absent means unrestricted, i.e. a source gate failing open. (A guard-widening leak of exactly this shape was caught and fixed here, with four regression tests each verified to fail against the leaking version.)

Episodic is the archivist's connection, decomposed. It needed far less than "a raw connection" implies: no ad-hoc SQL, ten typed calls, and two took no connection at all. Those two are host policy and stayed — deciding that a segment should end is a judgement about what a conversation is, and the host that renders segments is the only thing that can tune it. insert_turn now returns the row id instead of a follow-up SELECT last_insert_rowid(), which was reading connection-local state: an interleaved insert files a turn under the wrong segment. That is a bug fix, not just a saved round trip.

Per-profile stores needed no contract change in the end. Which store you talk to is settled when you are handed a driver — not per call — so the module's root object gained OpenStore(subdir) -> object_path and binding::for_subtree keys on it. No major bump, no migration, data stays where it is.

preferences came home — namespaces, prompt caps and similarity floors are product decisions, not storage. Worth recording: the reflex was to add a recall_relevant_by_vector method, but the engine's version was itself a default over query_namespace_hits, already exposed as recall_namespace_scored. Check for a default implementation before widening the contract — that is twice now.

Two reusable test providers (InMemoryProvider, FixedRecallProvider + guard_over) exist so conversions stop costing coverage. Both are #[doc(hidden)] pub, not #[cfg(test)] — integration tests under tests/ link the library without cfg(test), a trap this port fell into once.

Submission Checklist

• Tests added or updated — new suites for the four families, the guard decorators, preferences, archivist::boundary (12), plus 15 pre-existing install_for_tests order-dependence defects fixed (they passed only when a sibling test ran first).
• Diff coverage ≥ 80% — new code ships with unit tests alongside; see the note below on why the whole-lib run cannot be used as evidence.
• Coverage matrix updated — N/A: internal architecture change; no user-facing feature rows added, removed or renamed.
• All affected feature IDs listed — N/A: no matrix rows affected.
• No new external network dependencies introduced — memory calls go over the in-process bus.
• Manual smoke checklist updated — N/A: no release-cut surface changes; the module release is tracked separately below.
• Linked issue closed — N/A: this is the memory-module port programme rather than a single tracked issue; the design record is docs/specs/2026-08-13-memory-module-port.md.

Impact

This PR cannot merge until a TinyMemory release is cut. The host now advertises 18 families and OpenStore; the pinned 1.0.1 artifact serves 13. Roughly 40 tests are parked on OPENHUMAN_MODULE_PATH until then, and modules/registry.rs digests must be taken verbatim from the release's checksum.toml — never recomputed from a local build, or a re-cut release would silently replace what runs in-process.

Two pre-existing failures, both verified against merge-base c5d5eaab6, neither introduced here:

• session::runtime::tests::run_single_publishes_completed_and_error_events overflows a debug thread stack (passes under RUST_MIN_STACK=16777216). Because the abort kills the process, cargo test --lib prints no counts at all — so every verification in this PR is module-scoped, comparing per-module failing sets against a recorded baseline. The suite cannot currently be run end to end on main either.
• turn_triggers_configured_memory_agent_before_parent_prompt — run_subagent builds the memory agent its own model from config rather than inheriting the parent's, so the test's scripted provider sees one call instead of two.

Behaviour note for review: standing/situational preferences now read through the ambient guard rather than a session handle. For a dedicatedMemory profile that is a deliberate consistency fix — save_preference and the two read paths now agree on one store, where previously the write followed the profile and could diverge.

Verification: openhuman::memory:: failing set byte-identical to the 26-test baseline; memory::api, memory::guard, core::, modules, flows, tools, channels, cron, integrations, agent::learning all green; cargo check --tests and cargo fmt --check clean.

Related

Depends on:

• feat(memory): add the people domain and carve out the inert diff types tinycortex#148 — the people domain
• feat(module): five new capability families and OpenStore for per-subtree stores tinymemory#16 — the five families, OpenStore, contract (2, 2)

Merge order: tinycortex → tinymemory → cut the module release → this PR (with registry digests updated).

Design record: docs/specs/2026-08-13-memory-module-port.md.

@coderabbitai review

All actionable findings from the previous review are addressed and pushed:

• CLI memory seams — install_memory_host_seams now runs before global::init in both memory_cli::create_memory_client and subconscious_cli::run_tick.
• learning reset — delete failures propagate instead of being counted as no-ops; both call sites now share learning::cache::reset_non_pinned, with two tests (the failure one verified red against the old unwrap_or(false)).
• layout — memory/preferences.rs moved to memory/preferences/mod.rs.

Two threads are deliberately left open with reasoning rather than resolved:

• ArchivistHook's raw connection — you are right that it is still there. Migrating it onto the Episodic family today would point episodic capture at a released artifact that does not serve that family yet, taking it from working to silently not recording. Sequencing argument on the thread; it is a judgement call I would rather a maintainer make than close myself.
• id-addressed chunk reads — declined, since the engine has no scoped variant for them and a scope parameter that cannot be honoured would imply a guarantee it does not keep. The same point did surface a real bus-side fail-open in retrieve_children / retrieve_leaves, which is fixed in feat(module): five new capability families and OpenStore for per-subtree stores tinymemory#16.

@senamakel, I verified the reported fixes.

• install_memory_host_seams now runs before tinymemory_core::global::init in both CLI paths.
• reset_non_pinned now propagates delete errors. Both reset entry points call the shared helper. The tests cover successful reset and delete failure.
• Preferences now use src/openhuman/memory/preferences/mod.rs and its test module.

I also checked the two open threads against the current module boundary. Their constraints remain valid:

• ArchivistHook must retain the raw connection until the released TinyMemory artifact serves MemoryEpisodic.
• ID-addressed chunk reads cannot claim source-scope enforcement until the engine exposes a scoped operation.

I found no new actionable finding in the inspected follow-up changes. The compatible TinyMemory release remains required before merge.

Learning: In OpenHuman, `src/core/memory_cli.rs::create_memory_client` and `src/core/subconscious_cli.rs::run_tick` dispatch without the runtime bootstrap. They must call `install_memory_host_seams` before `tinymemory_core::global::init`. Memory host seams fail loudly by design to prevent silent degradation, such as writing vectors in the wrong embedding space or reporting an empty sync as successful. `install_memory_host_seams` is idempotent.

Learning: In the OpenHuman memory module port, `ArchivistHook` in `src/openhuman/agent/harness/archivist/types.rs` still uses `Option<Arc<parking_lot::Mutex<rusqlite::Connection>>>` because the currently released TinyMemory module artifact does not yet serve the `Episodic` capability family. Migrate `ArchivistHook`, `src/openhuman/agent/harness/archivist/lifecycle.rs`, and `src/openhuman/agent/harness/archivist/recap.rs` to `MemoryEpisodic` only after TinyMemory releases that family, OpenHuman pins compatible digests, and module-backed end-to-end tests can verify episodic capture.

Learning: `GuardedChunks::get_chunk`, `GuardedChunks::chunk_detail`, and `GuardedChunks::chunk_embeddings` enforce capability and tier admission but do not enforce source scope. The current TinyMemory engine has no scoped ID-addressed chunk-read operation. A correct source-scope enforcement fix requires an engine/API change that resolves the chunk source and authorizes it, or provides scoped variants.

Update the family count in the NeedsWiderSeam doc.

The doc says the call wants something "the thirteen capability families do not expose". This PR expands the contract to eighteen families, and it adds People, Chunks, Retrieval, Profile, and Episodic. This module is the migration inventory, so a stale count here misdirects whoever picks the upstream work up.

747-773: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

Consider memoizing scan across the tests in this module.

Five tests call scan, and each call re-reads every .rs file under src. That repeats a full source-tree read five times per test run. A OnceLock<BTreeSet<String>> keeps the ratchet behavior identical and pays the I/O once.

♻️ Proposed refactor

-fn scan() -> BTreeSet<String> {

Each caller then uses let found = scan(); with found.difference(...) unchanged, since &BTreeSet supports the same reads.

Log the error arms so a failed read is distinguishable from an absent capability.

Three paths degrade to empty with no record: the recall_namespace_scored Err arm at Line 87, list(...).unwrap_or_default() at Line 106, and the discarded get error at Line 113. The module doc justifies an empty result when the driver has no Retrieval capability, and that case is correct and silent. A genuine driver failure produces the same empty prompt block with nothing to diagnose it.

Keep the empty-result behavior. Add a debug or warn line on the error arms only. Log the namespace and the error, not preference content.

As per coding guidelines, "Changes lacking logging are incomplete." and "Never log secrets or full PII."

🩹 Proposed change for the recall path

-    let Ok(hits) = retrieval
+    let hits = match retrieval
         .recall_namespace_scored(namespace, query, limit, None)
