+# Porting the memory subsystem into the TinyMemory module
+
+**Goal.** Reach memory only through the loaded `tinymemory` TinyBus module, and
+drop `tinymemory`, `tinymemory-api`, `tinymemory-core`, `tinymemory-tinycortex`
+and the direct `tinycortex` memory surface from this crate's dependency graph.
+
+**Status.** Audit complete; port staged below.
+
+---
+
+## 1. What is already done
+
+The module architecture is finished and correct. This port is not building it —
+it is finishing a cutover that stopped half way.
+
+- `tinymemory-module` ships as a released `cdylib`, pinned with per-platform
+  digests in `src/openhuman/modules/registry.rs` (`TINYMEMORY`, v1.0.1).
+- `src/openhuman/modules/memory.rs` implements `MemoryProvider` by forwarding
+  ~53 methods — the full thirteen-family contract — one for one over the bus,
+  lazily, with `memory::api::wire` mapping errors on **both** ends.
+- The hard problem is solved. An out-of-crate engine still needs to embed,
+  summarise and extract, so three reverse bus services carry those calls back:
+  `ChatHost`, `EmbeddingHost` and `RuntimeHost`, served by
+  `src/openhuman/modules/memory_host.rs`. Credentials never cross —
+  `BusEmbeddingHost::resolve_api_key` returns `None` by construction.
+- `src/openhuman/memory/binding.rs` already refuses embedded drivers outright
+  and aliases the legacy `tinycortex` driver id onto the module.
+- `src/openhuman/memory/api/` is a host-local copy of the contract, and the
+  binding and the module client already compile against it rather than against
+  `tinymemory-api`.
+
+> ## ⚠ Scope correction (2026-08-15): §2's numbers understate the surface by ~3×
+>
+> The counts below were derived by grepping for explicit `tinymemory_core::`
+> imports. That misses most of the direct-engine access, because
+> `memory/mod.rs` **re-exports the engine's modules under host-local paths**:
+>
+> ```rust
+> pub use tinymemory_core::{ chat, global, queue, search, source_scope, store,
+>                            tinycortex, tree_policy, tree_source, util, … };
+> ```
+>
+> So a call site written `crate::openhuman::memory::store::chunks::store::list_chunks(…)`
+> is engine access that looks exactly like host-local code, and never appears in
+> a `tinymemory_core` grep.
+>
+> Measured properly: **100 files** reach the engine this way — 82 production,
+> and **52 of those outside `memory/`**. The heaviest users are
+> `store::chunks` (50), `store::create_memory` (31), `store::profile` (26),
+> `tree::tree_runtime` (22) and `tree::health` (20), concentrated in the agent
+> harness (`archivist`, `learning`, `session`) and `memory/read_rpc/`.
+>
+> `memory/read_rpc/` is the sharpest example: four files serving a live RPC
+> surface straight off the memory database, one of them (`admin.rs`) opening a
+> raw `rusqlite::Connection` on the DB path. None of them names
+> `tinymemory_core`.
+>
+> **What this changes.** Stages 2–3 are roughly three times the work the plan
+> assumed, and much of it is not "swap a call for a provider method" — whole
+> subsystems (`create_memory`, `profile`, `tree_runtime`, `health`) have no
+> contract representation and would each need a design decision like the ones
+> in §1d. The staging and sequencing still hold; the size estimate does not.
+>
+> **Measured empirically:** deleting just `store` from that re-export list —
+> one of ~24 names — breaks **89 call sites across 51 files** in production
+> code alone (`cargo check`, no tests). That is one re-export.
+>
+> **The facade was deleted first — see §2g.** Converting call sites from an
+> incomplete list could never converge while the facade kept generating new
+> ones; removing it turns the compiler into the inventory.
+
+## 2. What actually blocks dropping the crates
+
+**Roughly half the host's memory surface never went through `MemoryProvider`.**
+It reaches the engine directly, in-process.
+
+| Crate | References | Concentrated in |
+| --- | --- | --- |
+| `tinymemory_core` | 115 (30 real `use` sites) | `memory/{tools,query,tree,sync,host_impls}` |
+| `tinymemory_api::host` | 46 | `config/schema/*`, `inference/`, `cron/`, `integrations/` |
+| `tinycortex::memory` | 98 across 40 files | 56 of them **outside** `memory/` |
+
+### 2.1 The consequence is a split brain, not a style problem
+
+`memory_vector_search` calls `list_chunks(&config, &query)`
+(`memory/tools/search/vector_search.rs:160`). That resolves the workspace path
+and opens the same SQLite database the loaded module has already opened. With
+the module driver bound — which is now the only supported binding — the process
+runs **two independent engine instances over one database file**. The module is
+not authoritative today.
+
+### 2.2 The wire contract has real gaps
+
+These direct call sites are not all "provider calls written the lazy way". Four
+things they need have no representation in the thirteen families:
+
+| Missing | Needed by |
+| --- | --- |
+| **People** — `PeopleStore`, `PersonId`, `Handle`, `Interaction`. No capability family exists. | `memory/tools/people.rs`, `memory/people/` |
+| **Chunk-level store access** — `list_chunks`, `get_chunk`, `get_chunk_embeddings_for_signature_batch`, `ListChunksQuery`, `SourceKind` | `tools/search/{vector,hybrid,chunk_context}`, `tools/raw_store/*`, `query/*` |
+| **Retrieval primitives** — `fast_retrieve`/`FastRetrieveOptions`, `cover_window`, `search_entities`/`EntityKind`, `RetrievalHit`/`QueryResponse` | `query/{fast_walk,cover_window,search_entities,backend}` |
+| **Unified store types** — `MemoryKind`, `MemoryItemKind`, `UnifiedMemory` | `tools/search/hybrid_search.rs`, `tools/raw_store/kinds.rs` |
+
+Each needs a decision: widen the contract, or keep it host-side over data the
+provider already returns. Widening is not free — every method added to the wire
+is engine semantics both ends must agree on forever.
+
+### 2.3 Some of `tinymemory-core` belongs back in the host
+
+`tinymemory_core::{sync, composio_host, chat, learning_candidate, nlp_host}`
+and `memory/host_impls.rs` are orchestration, credentials and scheduling. By
+TinyMemory's own README split those are host concerns. They move **back** into
+OpenHuman rather than into the module, and `host_impls.rs` is deleted in favour
+of the bus services in `modules/memory_host.rs`.
+
+---
+
+## 3. The landmine: two live copies of the embedding signature
+
+`src/openhuman/memory/api/host/` is a near-duplicate of `tinymemory_api::host` —
+11 of 17 files byte-identical, 6 diverged. One divergence is dangerous.
+
+`format_embedding_signature` exists in **three** places with **two** behaviours:
+
+| Copy | Form |
+| --- | --- |
+| `tinymemory_api::host::embeddings` (crate) | `provider={name};model={model};dims={dims}` |
+| `tinycortex::memory::store::vectors` | byte-identical to the above, pinned by a parity test in `tinymemory/core/src/tinycortex/parity.rs` |
+| `memory/api/host/embeddings.rs` (host-local) | **length-prefixed**: `provider={len}:{name};model={len}:{model};dims={dims}` |
+
+The host-local copy is a *correctness fix* — it stops two distinct
+(provider, model) pairs colliding onto one signature, and carries a regression
+test for exactly that. It is also, right now, **dormant**:
+`src/openhuman/inference/embeddings/provider_trait.rs:20` re-exports the **crate**
+version, so every vector written today uses the naive form and matches the
+engine.
+
+**This port will make the host-local copy live.** Re-pointing
+`inference/embeddings` at `memory::api::host` — which stage 1 does — silently
+switches the signature format. Every stored embedding is keyed by that string,
+so the effect is not a compile error or a test failure: recall quietly matches
+nothing and the system re-embeds the entire corpus.
+
+**Therefore:** the signature change must be landed as its own deliberate change,
+upstream in TinyMemory first, so the crate, TinyCortex and the host move
+together with a migration for stored vectors — *not* as a side effect of a
+re-point. Until then the host-local copy must be reverted to the naive form so
+the two copies agree.
+
+Two lesser divergences, both harmless and both resolved in favour of host-local:
+`subsystems.rs` defaults the driver to `"tinymemory"` (crate still says
+`"tinycortex"`), and `mod.rs` gates test support on `#[cfg(test)]` rather than a
+feature.
+
+---
+
+## 4. Staged plan
+
+Each stage compiles and ships on its own.
+
+**Stage 0 — neutralise the landmine.**
+Revert `memory/api/host/embeddings.rs` to the naive signature form, keeping the
+collision test as `#[ignore]` with a pointer to this section. Open a TinyMemory
+issue for the real fix. *No behaviour change; makes every later stage safe.*
+
+> **Ordering constraint — `tinymemory-api` goes last, not first.**
+> `tinymemory_core::Config` is `dyn tinymemory_api::host::MemoryHostConfig`
+> (`tinymemory/core/src/lib.rs:32`), and `memory/host_impls.rs` implements eight
+> of these traits *for host types*. So for as long as `tinymemory-core` is a
+> dependency, the host's config must implement the **crate's** trait, and
+> re-pointing those references at the host-local copy would not compile. The
+> contract crate can only be dropped after the engine crate. Stages 1 and 5 were
+> the wrong way round in the first draft of this plan.
+
+**Stage 1 — close the wire gaps.**
+
+*Decision: all four surfaces are pushed down into TinyCortex and exposed through
+the TinyMemory contract. None is rebuilt host-side.* The host calls them over
+the bus like every other provider method, and the engine stays the single owner
+of storage and scoring.
+
+The audit shows this is far less new code than it looks, and **three of the four
+surfaces need no migration at all** — a first reading of the file lists suggested
+`tinymemory-core` carried a parallel implementation of retrieval and chunks. It
+does not:
+
+| Surface | Where it is today | Work |
+| --- | --- | --- |
+| Retrieval primitives | Algorithms already in `tinycortex::memory::retrieval`. `tinymemory-core/tree/retrieval/{cover,fast,search,drill_down,fetch,source}.rs` are 26–64 line **shims** that add source-scope filtering, limit truncation and logging — a policy layer, not a fork. | Expose only |
+| Chunk-level access | `tinymemory-core/store/chunks/store.rs` is a pure delegating wrapper — `engine_config(config)` then straight through to `tinycortex::memory::chunks`. | Expose only |
+| Unified store types | Same shim relationship over `tinycortex::memory::store`. | Expose only |
+| **People** | `tinymemory-core/people` — 2,138 LOC, its own SQLite database, its own migrations, a workspace-keyed process-global store, and **zero** TinyCortex references. | Genuine migration down into TinyCortex, then a new People capability family |
+
+### 1a. People migration — landed
+
+`tinymemory-core/people` (2,138 LOC, 34 tests) now lives at
+`tinycortex::memory::people`, behind a default-off `people` feature that implies
+`tokio` (the store shares its connection as an `Arc<tokio::sync::Mutex<_>>`).
+`tinymemory-core/people/mod.rs` is a re-export shim, matching `store/chunks`.
+Six `tracing::` calls became `log::` — all plain format strings, no structured
+fields — so `people` pulls in no dependency TinyCortex did not already have.
+
+**A live bug fell out of it.** The `contacts` gate was never forwarded. The
+reader has always lived below this crate, but `contacts` enabled four `objc2`
+crates *in the host* — which no file in `src/` names — and never reached
+`tinymemory-core`, where the `#[cfg]` is. So the macOS arm of `address_book.rs`
+was always compiled out: `SystemContactsSource` returned the empty stub,
+`people.refresh_address_book` reported success having seeded nothing, and macOS
+paid to compile four unused crates for it.
+
+This is the `voice` (#4901) / `tokenjuice-treesitter` (#4918) failure shape
+exactly — an unforwarded gate does not break the build, it silently does
+nothing. Fixed by forwarding (`contacts = ["tinymemory-core/contacts"]` →
+`tinycortex/contacts`), deleting the host's four unused `objc2` declarations,
+and adding `contacts_feature_reaches_the_engine_reader`, which asserts the
+property that was missing: that enabling the feature *here* changes what the
+reader does *there*. A `cfg!(feature = ...)` self-assertion would have passed
+throughout the bug.
+
+**Verification.** TinyCortex: 34 people tests pass; default and `contacts`
+builds clean. Host: builds clean both ways; feature-forwarding gate passes;
+`openhuman::memory::` is 711 passed / 26 failed / 1 ignored against `main`'s
+710 / 26 / 0 — the 26 are pre-existing and identical on a clean `main`
+checkout (they need the module artifact, which is not fetched locally), so this
+adds one passing test and one deliberately ignored one, and no new failures.
+
+### 1b. The People capability family — landed in the contract
+
+`Capability::People` is family fourteen, appended (never inserted — declaration
+order is bit order in the `Capabilities` bitset, so moving a variant would
+silently re-interpret an already-transmitted set). `CONTRACT_VERSION` goes
+`(2, 0)` → `(2, 1)`.
+
+**A new family, not methods on an existing one — the version rule forces this.**
+Adding these calls to `MemoryEntities` would have been a **major** bump, because
+a new method on a family a driver may already advertise is breaking: negotiation
+cannot protect a caller from a method an older driver never implemented. A new
+family is a minor bump, and an older driver simply does not advertise it.
+
+`MemoryPeople` carries seven methods, derived from the seven agent tools and
+four RPC controllers that exist today rather than guessed at: `list_people`,
+`get_person`, `resolve_handle`, `add_handle_alias`, `score_person`,
+`record_interaction`, `seed_from_address_book`. Its types are the contract's
+own — TinyCortex's `Person`/`Handle`/`Interaction` never cross — and identity
+travels as an opaque `PersonRef` string, since the contract does not promise
+every engine identifies people by UUID.
+
+Wired through: both contract copies, `NullMemoryProvider`, the `MemoryGuard`
+decorator (`GuardedPeople`), and the recording test fixture. In the guard,
+`resolve_handle` takes the **write** tier check when `create_if_missing` is set
+and the read check otherwise — classifying the whole method as a read would have
+handed a `readonly` operator a working insert through the back door.
+
+**A drift guard now holds the two contract copies together.** There are two
+copies of this contract — the host-local one the module *client* compiles
+against, and `tinymemory-api` which the module *service* compiles against — and
+they meet only over a bus, where a mismatch is not a type error but a method
+never called or a capability filtered away on one side. That duplication already
+produced one live defect (§3). Two tests now pin the families and the version
+across both copies; both were verified to actually fail by temporarily diverging
+a wire string, then to go green again. They are deleted with the
+`tinymemory-api` dependency in stage 5, when one copy remains.
+
+**Verification.** `openhuman::memory::api` 190 passed / 0 failed;
+`openhuman::memory::guard` 56 / 0; `core::all` 91 / 0; `openhuman::memory::`
+back to exactly the 26 pre-existing failures with no new ones; `cargo fmt`
+clean. (The full `--lib` run aborts on a pre-existing stack overflow in
+`agent::harness::session::runtime`, identical on a clean `main` checkout.)
+
+### 1c. Engine implementation, module service, host client — landed
+
+**Not in `tinymemory-tinycortex`.** That adapter holds only an
+`Arc<dyn Memory>` and documents its own scope as the mandatory three, because
+the optional families need a host's configuration. The implementation belongs
+to `tinymemory-module`'s `ModuleMemoryProvider`, which already holds
+`workspace_dir` and implements the other ten.
+
+**Conversions destructure; they do not round-trip through serde.** The module's
+`Self::cross` helper is a serde value round-trip, and it would have compiled
+and then failed at runtime on the first call: the engine's `Interaction` names
+its timestamp `ts` where the contract names it `at`. Explicit destructuring
+makes a renamed or added field a compile error instead — the rule
+`tinymemory-tinycortex::convert` already follows.
+
+Two smaller decisions worth keeping:
+
+- A malformed `PersonRef` is `Invalid`, not `NotFound`. `NotFound` would tell a
+  caller their id was well-formed but absent, sending them to look for a deleted
+  person rather than at the id they built.
+- Ranking sorts with `total_cmp`, not `partial_cmp`. A NaN from a degenerate
+  score makes `partial_cmp` return `None`, and `sort_by` on a non-total ordering
+  may panic or produce garbage order.
+
+Service side: seven methods on `ai.tinyhumans.tinymemory.Memory`, with
+`ListPeople` size-checked like the other list-returning methods — `limit` bounds
+the count but not the bytes. Host side: seven forwards through `module_call!`
+and an `as_people()` accessor.
+
+**The nested TinyCortex submodule was fast-forwarded** (`be7b395` → `566804c`,
+verified as an ancestor first) so the module crate can actually build and test
+against the engine change. That pointer bump is part of the release anyway.
+
+### Release-ordering hazard — read before shipping stage 2
+
+`ModuleMemoryProvider::capabilities()` answers `Capabilities::all()`
+**statically**. That set grew with the contract; the *artifact* only grows when a
+release is cut and `modules/registry.rs` is re-pinned. Between those moments the
+host over-claims, and `verify()` logs the disagreement without narrowing the
+advertised set.
+
+`people` is in that window now: served by the module source in this tree, not by
+the pinned `1.0.1` artifact. It is **inert today** because nothing in the host
+reaches `as_people()` yet. It stops being inert the moment the people RPC
+handlers are routed through the driver, so **that change and the module release
+must land together**. Documented at the `capabilities()` call site too.
+
+### 1d. The `Chunks` and `Retrieval` families — landed
+
+Families fifteen and sixteen, contract now `(2, 1)` with three additions (one
+minor bump covers all three — capability negotiation is what makes each safe).
+
+- **`MemoryChunks`** — `list_chunks`, `get_chunk`, `chunk_embeddings`. A
+  deliberately lower-level surface than the rest of the contract: it exists so a
+  host doing its *own* ranking (cosine + MMR, hybrid keyword/vector) can get the
+  rows without reaching around the driver into the engine's tables — which is
+  the split-brain this port exists to end.
+- **`MemoryRetrieval`** — `fast_retrieve`, `cover_window`, `search_entities`.
+
+Three decisions worth keeping:
+
+**Source scope had to become an explicit wire argument.** `tinymemory-core`'s
+in-process entry points read it from a **task-local**. That task-local belongs to
+the host's task and does not exist on the module's side of a bus call, so it
+would have read as `None` there — and `None` means *unrestricted*. A
+per-profile source gate would have failed open, silently, on every scoped
+retrieval. So `cover_window_scoped` and `fast_retrieve_scoped` were added
+alongside the ambient-scope originals (mirroring TinyCortex's own
+`cover_window_scoped`), and every scoped method on the wire takes `scope` as an
+argument and never infers it.
+
+**Entity kinds travel as strings, not as an enum.** The engine's `EntityKind` is
+`#[non_exhaustive]` and has grown twice. A closed enum on the wire means the
+first time the engine emits a kind this build has not heard of, the **response
+fails to deserialize** — a new entity category would break retrieval outright
+rather than showing up as an unfamiliar label. Responses therefore carry an open
+snake_case vocabulary. Requests are the opposite case and *are* validated: an
+unknown kind in a filter is `Invalid`, because silently matching nothing is
+indistinguishable from a genuine empty result.
+
+**`chunk_embeddings` sorts its result.** The engine returns a `HashMap`, whose
+iteration order varies per process; an otherwise-identical call would return a
+differently-ordered list. It is also the largest thing this interface returns —
+a 1536-dimension vector is roughly 10 KiB of JSON — so it is size-checked and
+refused by name rather than truncated, since a short batch is indistinguishable
+from "those chunks have no vector".
+
+**Verification.** Module crate 34/0 · host `memory::api` 190/0 ·
+`memory::guard` 56/0 · `core::all` 91/0 · `openhuman::memory::` failing set
+byte-identical to the pre-existing 26 · `cargo fmt` clean across all four
+crates.
+
+### Still open in stage 1
+
+- Routing the host's people / chunk / retrieval RPC + agent tools through the
+  driver (stage 2) — that is what makes these three families load-bearing and
+  what ends the split brain.
+- A module release, the digest update in `modules/registry.rs`, and the
+  TinyMemory-side submodule pointer commit.
+
+**Why People moves rather than staying put.** `tinymemory-core` survives this
+port — it is the module's own implementation crate, it just stops being an
+*OpenHuman* dependency — so leaving People there would compile. But the contract
+defines a capability and each engine implements it; a second engine binding in
+TinyCortex's place must bring its own People store. Storage belongs to the
+engine, which is exactly the split that makes the contract engine-neutral.
+
+Then: widen `MemoryProvider` and the capability set, extend the module service
+and the host client in `modules/memory.rs`, cut a TinyMemory module release and
+update the digests in `modules/registry.rs`.
+
+This is the largest stage and the only cross-repo-blocking one — it needs a
+published module release, taken verbatim from the release's `checksum.toml`,
+never recomputed from a local build.
+
+**Stage 2 — cut the direct engine calls over.** *(in progress)*
+Rewrite the 30 `tinymemory_core` call sites in `memory/{tools,query,tree}` onto
+the provider. Ends the split brain.
+
+### 2a. A guard bug caught before any call site moved
+
+The `GuardedChunks` / `GuardedRetrieval` decorators written in stage 1 forwarded
+the caller's `scope` argument **unchanged**. That is the exact widening leak
+`GuardPolicy::narrow_scope` exists to close, and its own docs record the earlier
+version of it: with a pass-through, a source-restricted turn can name a
+collection its restriction excluded and have that become the sole query
+predicate, so the restriction vanishes.
+
+Fixed to intersect via `narrow_scope`, matching `GuardedTree::query_source`.
+Four regression tests added (`families_tests.rs`), and each was verified to
+**fail** against the pass-through version before being kept — a scope test that
+cannot fail is worse than none.
+
+### 2b. Call sites converted
+
+| Tool | Was | Now |
+| --- | --- | --- |
+| `memory_vector_search` | `list_chunks(&config, …)` + `get_chunk_embeddings_for_signature_batch` | `as_chunks()` |
+| `memory_chunk_context` | `get_chunk` + `list_chunks` | `as_chunks()` |
+| `memory_store_raw_chunks` | `list_chunks` | `as_chunks()` |
+| `memory_tree` walk | `fast_retrieve` | `as_retrieval()` |
+| `memory_tree_cover_window` | `cover_window` | `as_retrieval()` |
+
+`memory_vector_search` is the case §2.1 names: it resolved the workspace path
+and opened the same SQLite database the loaded module already had open. It no
+longer touches the engine.
+
+Two of these dropped their `load_config_with_timeout()` entirely — the config
+load existed only to reach the database.
+
+**A test moved to `#[ignore]`, deliberately.**
+`raw_chunks::execute_success_path_returns_json_array` was a pure-SQLite test: it
+opened the workspace store in-process and read an empty table. That *is* the
+split brain. With no module artifact the binding now falls back to the null
+driver and the tool refuses — the correct answer, not a regression — so the test
+joins the module-backed set (`OPENHUMAN_MODULE_PATH`, own process), the same
+pattern the `tinydocs` tool tests use.
+
+**Verification.** `openhuman::memory::` 716 passed, failing set byte-identical
+to the pre-existing 26; `memory::guard` 60/0 (four new).
+
+### 2c. Second batch converted
+
+`memory_tree_search_entities`, `memory_store_raw_search` (both onto
+`as_retrieval()`), and `memory_tools_list` (a stale doc link only).
+`memory_chunk_context`'s remaining `chunk_source_allowed` call was re-pointed at
+the host's own `memory::source_scope` path, which is how `guard/policy.rs`
+already reaches it — the predicate is host *policy* over a host task-local, so
+relocating it properly is stage 4.
+
+**Entity-kind validation moved into the driver**, as flagged. The host used to
+`EntityKind::parse` before touching disk; the vocabulary is open on the wire
+(§1d) and the driver is its authority, so a host-side copy would either reject a
+kind the engine understands or drift out of date. The cost is named rather than
+hidden: a bad `kinds` value used to fail with no workspace and now needs a bound
+driver, so `execute_rejects_invalid_kind_after_validation` became a
+module-backed test rather than being quietly relaxed.
+
+**Eight tools are now off the engine entirely** — `vector_search`,
+`chunk_context`, `raw_chunks`, `raw_search`, `tool_memory/list`, `fast_walk`,
+`cover_window`, `search_entities` name no engine crate at all.
+
+**Six tests moved to `#[ignore]`, all for the same reason and none of them
+cosmetic.** Each asserted a success path by reading the workspace store
+in-process — which *is* the split brain. Two also ran the tool and then called
+the engine directly on the same workspace to assert both agreed; that second
+reader is precisely what this port removes, so the parity half is gone rather
+than reworked. This is a real loss of local coverage until the module release
+lands, not a cleanup.
+
+### 2d. The retrieval trio, `interaction_count`, and a merge from `origin/main`
+
+**Three methods added to `MemoryRetrieval`**, unblocking `backend.rs` and its
+three tool wrappers: `retrieve_source`, `retrieve_children`, `retrieve_leaves`.
+
+**The names are deliberate, and one was forced.** `MemoryTree` already has
+`drill_down` and `query_source` with *different* semantics — the tree family
+returns a node and its direct children, or the raw chunks filed under a source;
+these return ranked hits across the summary tree, several levels deep. Beyond
+the ambiguity, both families are served on **one bus object**, so `drill_down`
+collided outright and would not compile. Renaming the trio consistently
+(`retrieve_*`) resolves both.
+
+`query_source_scoped` joins `fast_retrieve_scoped` and `cover_window_scoped` in
+`tinymemory-core` for the same reason as §2c: a task-local scope does not cross
+a transport, and reading it as absent means unrestricted.
+
+**`RankedPerson::interaction_count`** added, restoring the field the people RPC
+payload carries. It is worth carrying for its own sake: a score alone cannot be
+read honestly, since 0.9 from three exchanges and 0.9 from three hundred are the
+same number and very different facts.
+
+**Merged `origin/main`** (90 commits). One thing to know: the merge commit
+correctly recorded `tinyagents → 30d6b3b` and `tinyflows → c242184`, and then
+the **auto-commit hook committed the stale worktree submodule pointers straight
+back**, reverting both gitlinks and breaking the build with an unresolved
+`tinyagents::harness::artifacts`. Restored from the merge commit and the
+submodules checked out to match. Worth watching for on any future merge in this
+repo — the hook cannot tell a stale submodule worktree from an intended change.
+
+**Now converted:** `backend.rs` (a doc comment is all that mentions the engine),
+plus `query_source`, `drill_down` and `fetch_leaves`. Five more success-path
+tests became module-backed, for the same reason as the earlier six — each read
+the workspace store in-process, and three carried a direct-engine parity half
+that has no second reader to agree with any more.
+
+**Verification.** `memory::` 708 passed / 26 failed — failing set identical to
+the post-merge baseline, no new failures · `memory::api` 190/0 ·
+`memory::guard` 60/0 · `core::all` 91/0 · module crate 34/0 · `cargo fmt` clean
+· both contract copies byte-identical apart from the intentional doctest path.
+
+### 2e. People converted
+
+`people/rpc.rs`, `people/schemas.rs`, `tools/people.rs` and a **third caller the
+first survey missed** — `flows/tinyflows/memory_adapter.rs`, which called
+`rpc::handle_list` directly — all now reach the driver's people family. None of
+the four names an engine crate.
+
+**`interaction_count` moved from `RankedPerson` to `PersonScore`.** `handle_score`
+needs it too, and duplicating the field would have let the two copies disagree.
+It belongs on the score anyway: the score and the sample size it was computed
+from should travel together, so every caller that gets one gets the other.
+
+Two deliberate behaviour changes, both surfaced rather than absorbed:
+
+- **`person_id` is no longer validated as a UUID host-side.** `PersonRef` is
+  opaque by contract — the driver issues the id and owns its format — so a
+  host-side UUID check would reject a driver that identifies people some other
+  way. `parse_person_id_rejects_non_uuid` was inverted into
+  `parse_person_id_accepts_any_non_empty_token`, with a companion asserting that
+  a *missing* id is still the host's to reject: that is a malformed call, not an
+  unrecognised identity.
+- **`permission_denied` in `people.refresh_address_book` is now always `false`.**
+  The contract reports a host without an address book, or without permission,
+  as `seeded: 0` rather than a distinct error — both mean the same thing to a
+  caller, and the alternative leaks a platform detail into an engine-neutral
+  contract. The field is kept so the published shape does not change, but
+  surfacing "grant Contacts access" now needs a host-side permission probe.
+
+**The RPC tests were rewritten, not gated.** They used to build a real
+in-memory `PeopleStore`; they now drive a small fake `MemoryPeople`. That is
+better coverage, not worse: ranking and scoring moved into the engine and are
+tested there, so what is left host-side is the published JSON shape and the fact
+that the driver's order is passed through rather than re-sorted — and there is
+now an explicit test that the host does **not** re-sort, since a host-side sort
+would silently override the ranking authority.
+
+### 2f. People's split brain closed at the store, not just the call sites
+
+Converting the callers left the *store* still being opened host-side. Four sites
+seeded a process-global that nothing read any more, so the host held a second
+connection to `<workspace>/people/people.db` — the file the module owns — purely
+to populate a global no handler consulted. All four are gone:
+
+| Site | Was |
+| --- | --- |
+| `core/runtime/context.rs` | boot seed under `StoreInitPlan.people` |
+| `security/credentials/ops.rs` | rebind after login, and after logout |
+| `desktop/app_state/ops.rs` | rebind on active-user switch |
+
+`CoreContext::people()` and the `StoreInitPlan.people` field went with them. The
+active-user rebinds needed no replacement: people resolves through the memory
+binding now, and `rebind_default_workspace` already moves that.
+
+**No host site opens the people database any more.** The engine still compiles
+it in — that is where it belongs.
+
+**Three context tests were removed rather than repointed**, and it is worth
+being precise about what that costs. `people_store_is_isolated_per_context_workspace`
+and `rebind_workspace_updates_context_store_resolution` proved per-context
+workspace isolation *using people as the example*; that property is proved
+unchanged by `memory_binding_is_isolated_per_context_workspace` and
+`rebind_workspace_updates_context_memory_binding`, which is what people resolves
+through now — so this is redundancy removed, not coverage lost.
+`people_rpc_uses_scoped_context_store` is different: it asserted a scoped
+`people_resolve` wrote workspace A and not B by opening **both stores directly**.
+There is no second reader to check against any more, and the isolation it tested
+belongs to the binding. `degraded_context_rejects_workspace_bound_stores` now
+asserts `workspace_dir()` directly — the gate every workspace-bound store passes
+through, and what `people()` was standing in for.
+
+**Verification.** `memory::` 713 passed / 26 failed, no new failures ·
+`core::runtime` 27/0 · `core::all` 91/0 · `memory::people` 13/0 ·
+`security::credentials` 183/0 · `desktop::app_state` 32/0 · `cargo fmt` clean.
+
+### 2g. The re-export facade is gone
+
+`memory/mod.rs` no longer re-exports **any** engine module. All ~24 names
+(`store`, `queue`, `global`, `chat`, `search`, `tinycortex`, `source_scope`,
+`util`, …) were removed and every call site now says `tinymemory_core::`
+explicitly — ~190 references across 86 files in `src/`, plus 14 integration
+tests and 4 binaries.
+
+This is not a conversion: **no behaviour changed**, because each rewritten path
+resolved to exactly the symbol it now names. What changed is visibility. Before,
+`crate::openhuman::memory::store::chunks::store::list_chunks(…)` was engine
+access indistinguishable from host-local code; a `tinymemory_core` grep returned
+30 files and the truth was 100. Now `grep tinymemory_core src/` **is** the
+inventory: **127 production files**, plus 94 naming `tinycortex`.
+
+Flat *type* re-exports (`memory::MemoryCategory`, `memory::Memory`) were kept
+and re-pointed. They still have to move to `memory::api`'s equivalents, but a
+type name hides nothing the way a module tree does.
+
+**A latent test bug surfaced and was fixed.** `agent::learning::startup`'s tests
+build a real `MemoryClient`, which needs the host seams wired — and that module
+never called `install_for_tests`. It passed only when another test in the same
+binary happened to run first; alone, or filtered to that module, it failed with
+"no EmbeddingHost installed". Verified pre-existing (`git log -S` shows the call
+was never there, and no commit in this work touched `host_impls.rs`, the only
+caller of `set_embedding_host`). The whole-suite runs never caught it because
+the pre-existing stack overflow in `agent::harness::session::runtime` aborts
+that binary first. One `Once`-guarded call fixes it: 144 → 145 passing.
+
+### 2h. The measured remaining surface, after the facade came down
+
+`grep tinymemory_core src/` is now the inventory. By engine module:
+
+| Module | Refs | What it is, and what it needs |
+| --- | --- | --- |
+| `store::chunks` | 52 | Partly `MemoryChunks` already; `memory/read_rpc/` uses `with_connection` and raw SQL and needs its own design |
+| `store::create_memory` | 31 | **30 of these are tests.** Only *one* production site constructs a `MemoryClient` — the "31 per-site decisions" reading was wrong. Test constructions are not a split brain and go when the dep does |
+| `store::profile` | 26 | The learning/profile subsystem (`ProfileFacet`, `FacetState`, `UserState` + SQL). No contract representation; needs a family design like §1d |
+| `global` | 40 | The process-global memory client — the same shape as the people global just deleted |
+| `queue` | 37 | The ingest job queue |
+| `tinycortex` | 26 | Direct engine reach-through |
+| `store::safety` | 14 | **Blocked, see below** |
+| `store::{UnifiedMemory,trees,segments,fts,content}` | ~45 | Engine internals with no contract analogue |
+
+**`store::safety` cannot simply come home.** TinyMemory's README puts redaction
+on the host, and the 2,065-LOC PII/secret detector currently sits in the engine
+— but the engine *uses* it on its own write paths in 14 places (`store::kv`,
+`goals::store`, `persona`). Moving it host-side would fork it, and a forked
+redactor is the same class of hazard as §3's forked embedding signature, with
+worse consequences. It is a third-crate extraction (the `tinydocs` /
+`tinywallet` shape), not a move.
+
+**Production vs test, measured.** The raw counts mix both. Split properly:
+**342 production references across 131 files**, and 125 test references. The
+split matters per cluster — `create_memory` is 1 production / 31 test, while
+`store::safety` is 14 / 0 and `store::profile` is 24 / 2. Test-side engine use
+is not a correctness problem; it disappears with the dependency.
+
+**Honest sizing for the rest.** Stages 2–5 need, at minimum: a contract family
+for the profile/learning subsystem; a decision for each `create_memory` call
+site; a design for `memory/read_rpc/`'s raw-SQL surface; the `global` and
+`queue` seams; a `tinysafety` extraction; then the module release, the
+`tinymemory-api` retirement (§ordering constraint) and the dep drop. That is a
+programme measured in weeks, not a tail-end sweep — and the number is now
+trustworthy, which it was not before §2g.
+
+### 2i. `hybrid_search` — the worst split brain, removed
+
+`memory_hybrid_search` called `UnifiedMemory::new(&config.workspace_dir, …)`:
+it constructed **an entire second engine** over the workspace the loaded module
+already owns. Not a stray query — a whole store instance, with its own
+embedder and its own SQLite handles.
+
+It needed scored hits with their signal breakdown so it could re-rank under a
+weight profile, which `MemoryRecall` does not expose — it returns ranked
+entries and keeps its scoring private. Added
+`MemoryRetrieval::recall_namespace_scored`, returning
+`NamespaceMemoryHit` (whose `score_breakdown` the contract *already* defined),
+so re-ranking is host policy over engine signals rather than a second retrieval
+implementation. Also added `MemoryChunks::chunk_detail`, a one-call inspection
+view — four accessors would have been four bus round trips per rendered row.
+
+**Adding methods to `MemoryRetrieval` keeps the version at (2, 1)**, which looks
+like it violates the major-bump rule. It does not: the rule protects *deployed*
+drivers, and `(2, 1)` has never shipped — `Retrieval` itself is new in it. Once
+the module release goes out, this stops being true.
+
+`MemoryClient::unified_handle` was added beside the existing `memory_handle`
+for the module's scored-recall path, documented as the narrower-surface
+exception it is.
+
+### 2j. Two pre-existing test defects, diagnosed and fixed
+
+Both surfaced because converting call sites changed which tests run together.
+
+- **`sync_pipeline_e2e_tests` was flaky**, alternating pass/fail across
+  identical runs (708/707). It counted events published across two tinybus task
+  hops after a single `yield_now()`. The file already had a `wait_for` helper
+  written for exactly this, with a doc comment explaining the two-hop problem —
+  three call sites just did not use it. One of them additionally needed to wait
+  for the **terminal** `completed` stage rather than any stage event.
+- **The same module never installed the host seams**, so it passed only when
+  another test in the binary had. Same defect as `agent::learning::startup`
+  (§2g), same one-line fix.
+
+Verified stable: 708 passed across three consecutive full runs, where it
+previously alternated.
+
+### 2k. The `Profile` capability family
+
+Family seventeen. `store::profile` + the `global::client_if_ready()` calls that
+existed only to reach `profile_store()` were one cluster, not two — the learning
+and archivist subsystems read and write the engine's facet table directly.
+
+`MemoryProfile` carries eleven methods over `ProfileFacet` / `FacetType` /
+`FacetState` / `UserState`. Three decisions worth keeping:
+
+- **The host owns the learning; the driver owns the rows.** `ProfileFacet`
+  carries a `stability` and a `state` the driver never computes — it records
+  what the host's stability detector decided. Extraction, scoring, promotion and
+  eviction all stay host-side; this family is only the persistence seam beneath
+  them.
+- **`user_state` outranks the score, and that is a contract obligation.**
+  `Pinned` stays active however low stability falls; `Forgotten` stays dropped
+  however much new evidence arrives — a user who says "forget that" must not
+  have it re-learned. `drop_facets_below` is documented as required to honour
+  both, so a future driver cannot quietly sweep against an override.
+- **`workflow_identity_matches` returns `bool`, not `Result<bool>`**, matching
+  the engine method it replaces. Every caller is an "is this row the user?"
+  predicate whose only sane reading of a failure is *no*; threading a `Result`
+  through them invites an `unwrap_or(true)` somewhere. The guard, the wire and
+  the client each answer `false` on refusal, absence and transport failure
+  respectively — the one place the contract deliberately swallows an error, and
+  it says so.
+
+`ProfileStore`'s methods are synchronous and hold a `parking_lot::Mutex` across
+SQLite, so every module-side call goes through `spawn_blocking` rather than
+being awaited on the runtime thread.
+
+Wired through both contract copies, the null driver, the guard, the fixture, the
+module implementation, the bus service and the host client. **Call sites are not
+converted yet** — that is the next step, and it is what makes the family
+load-bearing.
+
+### 2l. The learning subsystem converted onto `MemoryProfile`
+
+`FacetCache` reads and writes through the driver now, and the subsystem went
+async with it: `load_learned_from_cache`, `StabilityDetector::rebuild`,
+`ProfileMdRenderer::render`, and every call site in `schemas`, `tools`,
+`scheduler` and `startup`.
+
+**Async-ifying removed work.** `render()` was wrapped in `spawn_blocking`
+specifically to keep in-process SQLite off the executor. With the store behind
+the module there is no blocking I/O left to move, so the hop is gone.
+
+**No coverage was lost.** The ~50 learning tests built real in-memory SQLite
+stores. Rather than park them on `OPENHUMAN_MODULE_PATH`, they drive an
+in-memory `MemoryProfile` (`agent/learning/test_profile.rs`) — those tests are
+about stability scoring and prompt rendering, not persistence. 145 pass.
+
+Two defects the tests caught in this work:
+
+- **The fake's `drop_facets_below` was wrong**, and the existing assertions
+  failed on it. The engine sweeps only rows already in `FacetState::Dropped`,
+  and protects only `Pinned`. The contract doc had **overstated the guarantee**
+  by claiming `Forgotten` was protected too; corrected, with the reason the
+  asymmetry is deliberate — a Forgotten facet is already Dropped and is meant to
+  be collected.
+- **`test_profile` was first written `#[cfg(test)]`**, which integration tests
+  cannot see — the exact trap `ProfileStore::for_tests` documents. Now
+  `#[doc(hidden)] pub`.
+
+**The bypass allowlist shrank.** Five entries justified by *"the contract has no
+profile family"* are gone. One was added — a boot-time `binding::for_workspace`
+that resolves a **guard** (not a raw client) for a known workspace, as
+`active_memory_guard`'s own fallback does — with that reason recorded in both
+the test and `docs/specs/memory-guard-allowlist.md`.
+
+### 2m. The `Arc<dyn Memory>` seam — attempted, reverted, and why
+
+`AgentExperienceStore` looked like the next bounded conversion: it uses only
+`get` / `list` / `store`, all in `MemoryCore`. It was converted, and then
+reverted.
+
+`agent/harness/session/turn/core.rs` builds experience stores from the
+session's own `Arc<dyn Memory>` **and** from a second, *shared* experience
+memory. The guard is per-workspace; the session may legitimately hold two
+memory handles. Converting only the `ops.rs` door would have left
+`AgentExperienceStore` with two constructors, one guarded and one not — which
+the bypass allowlist would rightly flag, and which is worse than the current
+state.
+
+So `Arc<dyn Memory>` is not a call-site cluster at all: it is a **seam**
+threaded through the session builder, the flows adapter and the experience
+store, and it has to be replaced as one design rather than file by file. That
+is the largest single item left, and it is the reason the remaining `global`
+sites cannot simply be deleted the way the people global was.
+
+### 2n. A way through the `Arc<dyn Memory>` seam
+
+The seam looked un-splittable in §2m because every consumer is *handed* a
+memory handle by `build_tools(memory: Arc<dyn Memory>, …)`, which is fed from
+the session builder. Converting one consumer meant converting the constructor,
+which meant converting the builder.
+
+There is a way through, and this port already established it: **a converted tool
+resolves the guard itself**. `vector_search`, `chunk_context`, `raw_chunks`,
+`fast_walk` and the rest hold no handle — they call `active_memory_guard()` per
+invocation. Applying that to a seam consumer removes its dependency on the
+constructor parameter entirely, and the parameter dies of disuse once the last
+consumer stops reading it.
+
+`memory_recall`, `memory_store` and `memory_forget` are converted on that
+pattern: each is now a unit struct (or holds only its `SecurityPolicy`), and
+`build_tools` no longer passes them a handle. Holder count 33 → 30.
+
+Two details the conversion surfaced:
+
+- **`recall`'s options changed shape.** The engine trait takes a borrowed
+  `RecallOpts`; the contract takes `&OwnedRecallOpts` plus an explicit `scope`.
+  `None` is passed for scope, which is not "unrestricted" — the guard
+  intersects it with the ambient allowlist, so it can only narrow.
+- **`store` gained a taint argument.** The engine's `store` has none; the
+  contract requires one because a driver that could default provenance could
+  launder external content as internal. The tool passes `MemoryTaint::default()`
+  as a *request*, and the guard stamps the effective value.
+
+Their engine-backed tests join the module-backed set (the read-back goes through
+a real `UnifiedMemory`, so those assertions need the artifact). `name_and_schema`
+stopped needing a store at all.
+
+### 2o. The seam's root is four call sites, not thirty
+
+Triaging the remaining `Arc<dyn Memory>` holders against the contract:
+
+| What they need | Files | Status |
+| --- | --- | --- |
+| `store` / `get` / `forget` / `list` / `recall` | most | **covered** — `MemoryCore` + `MemoryRecall` |
+| `namespace_summaries()` | 7 | **covered** — the contract's `namespaces()` has the identical signature and return type; it is a rename |
+| `count()` | 3 | **test-only.** No production call site uses the trait's `count` |
+| `recall_relevant_by_vector()` | 0 | unused anywhere |
+| `memory_handle()` | 4 | **the root** |
+| `tool_memory_store(…)` / `preferences::…` | 3 | engine helpers taking `&Arc<dyn Memory>` |
+
+So the seam is not thirty independent conversions. Nearly every holder just
+*receives* a handle; only four production sites **mint** one —
+`agent/experience/ops.rs` (×2), `agent/harness/session/builder/factory.rs`,
+`flows/bus.rs` and `flows/tinyflows/memory_adapter.rs`, each calling
+`MemoryClient::memory_handle()`.
+
+Convert those four to hand out the guard and the downstream holders change type
+mechanically, because what they call is already in the contract. That is the
+finish line for the seam, and it is a much smaller target than the holder count
+suggests.
+
+Two consumers need engine helpers that take `&Arc<dyn Memory>` —
+`tool_memory_store` and `preferences::recall_related_preferences`. Those are
+host-layer helpers living engine-side; they come home with stage 4 rather than
+being wrapped.
+
+### 2p. ⚠ The seam root is blocked on an architectural decision, not on typing
+
+Converting the four `memory_handle()` roots turns out not to be mechanical, and
+the reason is worth stating precisely because it is **not in the original plan
+and it gates the rest of the port**.
+
+`agent/harness/session/builder/factory.rs` does not take a handle to the
+workspace's memory. It **constructs its own engine instance**:
+
+```rust
+let session_memory = memory_store::factories::create_session_memory_with_local_ai(
+    …, &config.workspace_dir, &memory_subdir,   // "memory" | "memory-<profile-id>"
+)?;
+let archivist_connection = session_memory.sqlite_connection;
+let memory: Arc<dyn Memory> = Arc::from(session_memory.memory);
+```
+
+Two things fall out, and the module architecture accommodates neither:
+
+1. **Per-profile memory subtrees.** A profile with `dedicated_memory` gets its
+   own store at `<workspace>/memory-<id>`, which is the whole point of that
+   feature — isolation. The contract and the binding address a **workspace**
+   (`binding::for_workspace(workspace_dir, cfg)`); there is no notion of "open
+   the store rooted at subdirectory X". One loaded module serving one store per
+   workspace cannot express this.
+2. **A raw `sqlite_connection` handed to the archivist.** `ArchivistHook::new`
+   takes the live SQLite connection out of the session's memory. A connection
+   cannot cross a bus, so there is no forwarding fix — the archivist's storage
+   has to be re-homed, not re-routed.
+
+There is also a third store in play: a dedicated-memory session *additionally*
+holds `shared_experience_memory`, a handle to the **global** store, so
+pre-profile unstamped experiences stay recallable. So one session can legitimately
+hold two stores plus a raw connection.
+
+**This is a design decision, not a conversion.** The options are roughly:
+extend the contract so a driver can serve named stores within a workspace
+(a real widening, and the module would need to load or multiplex per subtree);
+or bind one module per memory subtree; or re-scope `dedicated_memory` so
+isolation is expressed inside one store rather than by a separate database. Each
+changes user-visible behaviour or the module's lifecycle, and none should be
+picked without an explicit call.
+
+Everything downstream of these four sites is mechanical once that is settled —
+§2o shows the receivers need only what the contract already has. But the roots
+themselves cannot be converted until per-profile memory has an answer.
+
+### 2q. An in-memory provider, so conversions stop costing coverage
+
+Every seam conversion had been paying the same toll: the consumer's tests handed
+it a real `UnifiedMemory` over a temp dir and asserted a genuine round trip, and
+converting to the guard turned them into `#[ignore]`d module-backed tests. That
+is ~36 tests parked so far.
+
+`memory/guard/in_memory.rs` ends that. It is a `HashMap` behind a mutex
+implementing the **mandatory three**, so it can be wrapped in a *real*
+`MemoryGuard` — `guarded_in_memory()` returns both. A converted consumer's tests
+keep their round-trip assertions, and gain the policy layer on the path where
+production has it.
+
+`RecordingProvider` could not serve: it records calls and answers empty, which
+proves a call was made but never that the data came back.
+
+Two deliberate limits, stated in the module so nobody mistakes it for the
+engine: `recall` is a substring match, not ranked retrieval (a test about
+*ordering* must use the real engine), and `list`/`namespaces` sort explicitly
+because a `HashMap`'s iteration order would make otherwise-identical assertions
+flaky. It is `#[doc(hidden)] pub`, not `#[cfg(test)]`, for the integration-test
+reason this port has already tripped over twice.
+
+**First use: `flows/bus.rs`.** The run-digest subscriber now resolves the guard,
+and its `store_with_taint` call became `store` — the contract carries taint on
+the one door, so the engine trait's second door is unnecessary. All 33 bus tests
+keep their assertions and pass.
+
+The bypass allowlist lost its two `flows/bus.rs` entries with it.
+
+**A third order-dependent test defect surfaced** — `flows::ops` tests build an
+agent, which constructs a memory client, which needs the host seams; they had
+never installed them and passed only on ordering. Same one-line fix as
+`agent::learning::startup` and `sync_pipeline_e2e_tests`. That is three
+independent instances of the same latent defect this port has now found and
+fixed.
+
+### 2r. Both flows roots converted
+
+`flows/tinyflows/memory_adapter.rs` and the `flows/memory_tools.rs` helpers it
+delegates to (`cross_flow_recall`, `FlowMemoryRecallTool`,
+`FlowMemoryRememberTool`) now go through the guarded driver. Two of the four
+`memory_handle()` roots are gone; the remaining two are the ones downstream of
+the per-profile decision in §2p.
+
+Three shape changes, each removing a door rather than adding one:
+
+- **`namespace_summaries()` → `namespaces()`.** Identical signature and return
+  type; the contract simply names it differently. This is what makes the seven
+  files that call it mechanical.
+- **`store_with_taint(…)` → `store(…)`.** The contract carries taint on the one
+  store method, so the engine trait's second door has no counterpart and needs
+  none.
+- **`is_potentially_untrusted` stopped taking a `MemoryEntry`.** Two entry types
+  are in play during the port, and the predicate needs neither — it reads a
+  namespace and a key. It takes those now, so callers on either side use it
+  without conversion, and the signature states what it depends on.
+
+The bypass allowlist lost both `memory_adapter.rs` entries. Across this port it
+has now shed nine: five profile/facet, two `flows/bus.rs`, two
+`memory_adapter.rs` — against one added (a boot-time guard resolution, with a
+reason). Its own rule is that it may shrink and must never grow.
+
+### 2s. The tool registry stopped taking a memory handle
+
+`all_tools` / `all_tools_with_runtime` took an `Arc<dyn Memory>` and threaded it
+into exactly **two** tools: `SavePreferenceTool` and `ToolStatsTool`. Each used
+one mandatory-family method (`forget`, `list`). Converting those two to resolve
+the guarded driver per call made the parameter dead, and dropping it collapsed
+**both remaining engine-construction sites** in one step:
+
+| Site | Was |
+| --- | --- |
+| `channels/runtime/startup.rs` | `create_memory_with_local_ai(...)`, plus a second fallback construction with `embedding_provider = "none"` when the embedder failed (#3712) |
+| `runtime/node/ops.rs` | `tinymemory_core::store::create_memory_with_local_ai(...)` |
+
+The #3712 fallback goes away with the construction it protected: there is no
+embedder to fail to build here any more, because the host no longer builds a
+store at all. The degradation it bought — channels still start when the
+embedding provider is misconfigured — now belongs to the driver, which is a
+better place for it: it applied to one of the four construction sites, and the
+other three had no such protection.
+
+`ChannelRuntimeContext.memory` became `Arc<MemoryGuard>` in the same change,
+and `build_memory_context` with it.
+
+### 2t. `preferences` came home, and cost the contract nothing
+
+`tinymemory_core::preferences` was host policy living in the engine: which two
+namespaces the lanes use, how many standing preferences a prompt may carry, and
+the similarity floors for Lane-B recall and the contradiction check. A second
+engine would have had to reimplement all of it identically or the product would
+change underneath it. It is now `src/openhuman/memory/preferences.rs`.
+
+**The move needed no new contract surface**, which is worth recording because
+the reflex was to add a `recall_relevant_by_vector` method. The engine's
+version was itself a *default* method over `query_namespace_hits` — the query
+the contract already exposes as `MemoryRetrieval::recall_namespace_scored` — so
+the filter (keep hits whose `score_breakdown.vector_similarity` clears the
+floor) is reproduced host-side verbatim. Check for a default implementation
+before widening the contract; twice now the surface was already there.
+
+A driver without `Capability::Retrieval` yields **no** preferences rather than
+an error, preserving the engine default that let keyword-only backends opt out.
+Both callers degrade correctly: an absent Lane-B block and an absent
+contradiction check, rather than a failed chat turn or a failed preference
+write.
+
+The two `KwEmbedder`-based contradiction tests were deleted, not ported. They
+existed to make vector similarity move at all through a real `UnifiedMemory`;
+the new tests script the score breakdown directly, which pins the similarity
+gate the embedder was only an indirect way of reaching.
+
+### 2u. Two reusable test providers now exist
+
+Conversions kept costing test coverage, so `memory/guard/in_memory.rs` now
+carries two, both `#[doc(hidden)] pub` rather than `#[cfg(test)]` so integration
+tests under `tests/` can see them:
+
+- **`InMemoryProvider`** — real storage; for round trips. `recall` substring-matches.
+- **`FixedRecallProvider`** — `recall` answers a scripted list whatever the
+  query; everything else inert. For the channel/context tests that assert on
+  what the *caller* does with a result set (scoring filter, truncation, budget),
+  where recall itself must be a constant.
+
+`guard_over(provider)` wraps either — or a test's own provider — in a real
+`MemoryGuard`, so these run through the same policy decorator production uses.
+
+**Where a fake is not enough.** A test whose assertion turns on *ranked* recall
+cannot use either, and gets parked on `OPENHUMAN_MODULE_PATH` with the existing
+reason string. Three joined that set here: the two `tool_stats` tests, the
+`save_preference` storage tests, and the channels autosave test (which asserts
+an autosaved turn is later recalled by a differently-worded question — ranking,
+not substring).
+
+### 2v. A pre-existing debug-stack overflow in the whole-lib run
+
+`agent::harness::session::runtime::tests::run_single_publishes_completed_and_error_events`
+aborts the **entire** `cargo test --lib` run with a stack overflow. It is deep
+frames, not recursion: it passes under `RUST_MIN_STACK=16777216`.
+
+**It is not this port's.** Verified by building the branch's merge-base with
+`main` (`c5d5eaab6`) in a scratch worktree and running the single test there —
+same overflow, same abort. Reverting this port's two edits to the turn body did
+not change it either.
+
+It matters here for one practical reason: because the abort kills the process,
+**a whole-lib run reports nothing at all** — no counts, no failure list. Every
+verification in this port is therefore module-scoped, and a claim of "no new
+failures" rests on comparing per-module failing sets against the recorded
+baseline, not on a green whole-suite run. Anyone re-checking this work should
+know that the suite cannot currently be run end to end, and that this is true
+of `main` as well.
+
+Worth knowing separately when adding an `await` to the turn body, since it is
+already close to the edge: `situational_preferences` and `standing_preferences`
+are free functions rather than inline blocks so their state machines stay off
+the caller's frame.
+
+A second pre-existing failure surfaced by the same sweep, verified the same way
+against `c5d5eaab6`:
+`agent::harness::session::turn::tests::turn_triggers_configured_memory_agent_before_parent_prompt`
+asserts the parent turn answers `"parent final"` and gets the *memory agent's*
+scripted reply instead. Only one model call reaches the test's `SequenceProvider`,
+because `run_subagent` builds the memory agent its own model from config rather
+than inheriting the parent's — so the subagent never consumes response #0 and
+the parent does. Identical on the merge-base; not this port's, and not fixed
+here.
+
+### 2w. Twelve more `install_for_tests` order-dependence defects
+
+The module-by-module sweep found twelve tests that build an agent or a memory
+client without calling `host_impls::install_for_tests()` — nine in
+`integrations::composio::ops_tests`, three in `cron::scheduler_tests`. Each
+fails with *"no EmbeddingHost installed"* when its module is run on its own and
+passes in a bigger run, because the installer is `Once`-guarded and some earlier
+test happened to call it.
+
+That brings this port's total to **fifteen** (after `agent::learning::startup`,
+`sync_pipeline_e2e_tests` and `flows::ops`). The pattern is consistent enough to
+state as a rule: **a test that builds an agent, a memory client or a cron job
+must install the seam itself.** Relying on a sibling makes the test's own
+scoped run a false negative, which is exactly how these survived — nobody runs
+`cargo test --lib openhuman::cron` in CI, and the whole-lib run aborts (§2v)
+before the counts print.
+
+### 2x. The raw SQLite connection is gone — `Episodic`, the 18th family
+
+The archivist post-turn hook held the last live `rusqlite::Connection` in the
+host, handed to it straight out of the session factory. A connection cannot
+cross a bus, so this was the hard half of the blocker: while it existed, the
+engine could not leave regardless of what happened to the store selector.
+
+It turned out to be much less entangled than "a raw connection" suggests. The
+hook issued **no ad-hoc SQL** and knew nothing of the schema; it called ten
+typed free functions, and **two of those took no connection at all**. So the
+split was already there, waiting to be named:
+
+| Went to the contract (`Capability::Episodic`) | Stayed host-side (`archivist::boundary`) |
+| --- | --- |
+| `insert_turn`, `session_turns` | `detect_boundary` + its `BoundaryConfig` / `BoundaryDecision` / `BoundaryReason` |
+| `open_segment`, `create_segment`, `append_turn` | `incremental_mean_embedding` |
+| `close_segment`, `set_segment_summary`, `upsert_segment_embedding` | `fallback_summary` |
+
+Persisting a segment is storage. Deciding *that a segment should end* — how long
+a pause means the subject moved on, how many turns is too many, which phrases
+announce a change of topic — is a product judgement about what a conversation
+is, and the host that renders these segments is the only thing that can tune it
+against what users see. The thresholds are carried over verbatim: this is a
+move, not a retune, so a regression stays attributable.
+
+**`insert_turn` returns the id, and that is a bug fix, not just a round trip
+saved.** The old code inserted a row and then asked `SELECT last_insert_rowid()`
+on the same connection. That is *connection-local* state: any interleaved insert
+from another task yields the wrong id and files the turn under the wrong
+segment. Returning the id from the insert removes the race and the second hop
+together.
+
+`ConversationSegment` carries `embedding` for the same reason the family exists
+at all — boundary detection is host policy but reads the driver's centroid, so
+it comes back on the read rather than costing a second call.
+
+Version: **(2, 1) → (2, 2)**, a minor bump, per the rule that a new family is
+made safe by capability negotiation alone.
+
+Both contract copies, the guard decorator (`GuardedEpisodic`), the
+`RecordingProvider` fake and the four count pins moved together. The count pins
+are worth keeping literal: each one forced a deliberate look rather than sliding
+past, which is exactly what caught `every_capability_family_is_accounted_for_in_the_rpc_surface`
+needing an entry.
+
+### 2y. The module driver ignores the workspace it is bound for
+
+Found while sizing the store-selector half, and it is worth stating plainly
+because it changes what that work is:
+
+`binding::for_workspace` caches on `(workspace_dir, cfg)` and `build()` logs
+`workspace=…`, but `module_provider(_workspace_dir)` **discards the argument**.
+`ModuleMemoryProvider` resolves against the `Config` published once at boot by
+`set_modules_policy`, and reaches a single object path on the bus. So today the
+module serves exactly **one store per process** — not one per workspace, and
+certainly not one per profile subtree. Two workspaces get two `MemoryBinding`s
+that talk to the same store.
+
+That means the `dedicated_memory` question is not "how do we keep the existing
+per-subtree behaviour through the bus" — there is no per-subtree behaviour on
+the module path to keep.
+
+### 2z. `OpenStore` — the module opens stores, so the contract does not change
+
+Two candidates presented themselves first, and both were wrong:
+
+- **A store selector on the wire** — the object is a singleton by construction,
+  so selecting a store means a parameter on *every method of all 18 families*: a
+  major contract bump, to express something that is not a property of a memory
+  operation at all.
+- **Profile subtrees become namespaces** — no contract change, but it relocates
+  user data on disk and needs a migration.
+
+The third dissolves the problem. **Which store you are talking to is settled
+when you are handed a driver**, exactly like which workspace you are bound to —
+it was never a per-call fact. tinybus already supports `serve_at` on many paths,
+so the module's root object gained one method:
+
+```text
+OpenStore(memory_subdir) -> object_path
+```
+
+Each opened store is an ordinary `MemoryService` exporting the identical
+interface. `MemoryProvider` still describes one store; a proxy still talks to
+one store. **No contract change, no migration, and paths on disk are exactly
+where they already were.**
+
+What landed:
+
+| Side | Change |
+| --- | --- |
+| `tinymemory-core` | `create_memory_client_in_subdir` — the existing client factory hardcoded `"memory"` |
+| `tinymemory-module` | `StoreOpener`, `OpenStore`, per-subtree object paths, `MemoryService::root` vs `::new` |
+| host | `ModuleMemoryProvider::in_subdir` + lazy `OpenStore` resolution; `binding::for_subtree`; the cache key gained the subtree |
+
+Four decisions worth keeping:
+
+- **Only the root object opens stores.** An opened store has no `StoreOpener`,
+  so the recursion is finite by construction rather than by a depth check.
+- **Idempotent per subtree, and recorded only after `serve_at` succeeds.** Two
+  live handles to one SQLite file is not hypothetical — the engine migrates on
+  open, and concurrent migrations on one file corrupt it invisibly. Caching the
+  path before the serve succeeded would strand callers on a path nothing
+  answers.
+- **The object path is derived and character-checked, never free-form.** A
+  subdir arrives from a profile id; an id that fails validation must produce a
+  refusal, not a malformed bus path. The rejection message does not echo it —
+  it is user data.
+- **`in_subdir("memory")` is `None`.** Callers pass whatever
+  `memory_subdir_for_suffix` produced without special-casing the shared tree,
+  and the shared tree costs nothing extra because the root object is served
+  eagerly at setup.
+
+This also fixes the workspace-ignoring bug above for the axis that matters: the
+workspace still comes from the boot policy (the module is loaded once per
+process and captures it at setup), but the **subtree** is now per binding.
+
+### Still open in stage 2
+
+| File | Why it is not converted |
+| --- | --- |
+| `query/backend.rs` + its three tool wrappers (`drill_down`, `fetch_leaves`, `query_source`) | **Needs contract surface that does not exist.** `backend::query_source(config, source_id, source_kind, time_window_days, query, limit) -> QueryResponse` has a different shape from `MemoryTree::query_source`, and `fetch_leaves` has no equivalent at all. Three more `MemoryRetrieval` methods, or a widened `MemoryTree` — the latter would be a **major** contract bump. |
+| `tools/people.rs` + `people/rpc.rs` | The `People` family exists, but the RPC layer is the real call site and its `people_list` payload carries `interaction_count`, which `RankedPerson` does not. Either the contract gains that field or the RPC wire shape changes; `schemas_tests` pins the current one. |
+| `tools/diff.rs` | Uses `tinymemory_core::sources::{get_source, list_sources}` — the source *registry*, which is host-layer config, not engine storage. Belongs in stage 4, not behind the driver. |
+| `tools/raw_store/kinds.rs` | `MemoryKind` is the engine's **storage-shape** catalog (raw / chunk / entity / tree / vector / kv / contact) and is unrelated to the contract's `MemoryItemKind`. The tool is a static enumeration with no database access, so there is nothing to route — the question is whether the contract should expose engine storage shapes at all, or whether the tool should go. Needs a decision. |
+| `tools/search/hybrid_search.rs` | Uses `UnifiedMemory` + `MemoryItemKind` + `tinycortex::WeightProfile` — a whole retrieval facade rather than a single call. Largest remaining conversion. |
+| `query/ingest_document.rs`, `query/query_source.rs` | Type-only imports (`SourceKind`, `SourceRef`) plus test-only direct engine calls; trivial once `backend.rs` is resolved. |
+
+**Stage 3 — the 98 `tinycortex::memory` references.**
+56 sit outside `memory/` (`agent/`, `threads/`, `subconscious/`, `channels/`,
+`security/`), mostly `tinycortex::memory::conversations`. Route through the
+provider or through a host-owned conversation store.
+
+**Stage 4 — bring host-layer code home, and drop `tinymemory-core`.**
+Move `sync`, `composio_host`, `chat`, `learning_candidate`, `nlp_host` out of
+`tinymemory-core` into `memory/`. Delete `host_impls.rs` in favour of the bus
+services in `modules/memory_host.rs`.
+
+**Stage 5 — retire `tinymemory-api`.**
+Only reachable once stage 4 lands, per the ordering constraint above. Re-point
+the 46 `tinymemory_api::host` references at the host-local `memory::api::host`
+and reconcile the 6 diverged files. Touches `config/schema/*`, `inference/`,
+`cron/scheduler_gate`, `integrations/composio`. These config types are persisted
+serde — field names, defaults and `#[serde(...)]` attributes must not move.
+Drop the crate cross-check test in `memory/api/host/embeddings.rs`; the golden
+test beside it is what carries the format guarantee afterwards.
+
+**Stage 6 — drop the deps and ratchet.**
+Remove all five entries from `Cargo.toml`, forward the gate to
+`app/src-tauri/Cargo.toml`, and re-baseline `scripts/kernel-floor.limits` —
+`libsqlite3-sys` should leave the kernel profile with the engine.
+
+## 5. Verification
+
+- Both-ways gate tests in `src/core/all_tests.rs` for any new feature gating.
+- A regression test per stage, failing before and passing after.
+- `scripts/check-kernel-floor.sh` re-baselined only at stage 6, and the shed
+  written back — an unratcheted improvement grows back unnoticed.
+- Prove each claimed shed with `scripts/assert-shed.sh`, never `cargo tree -i`.

+//! # Why this is host-side
+//!
+//! These functions came from the engine's `segments` module, and unlike their
+//! neighbours there they never touched the database: every one of them is a
+//! pure function over values the caller already holds. That is what makes the
+//! split obvious. Persisting a segment is storage; deciding *that a segment
+//! should end* is a product judgement about what a conversation is — how long a
+//! pause has to be before the subject has moved on, how many turns is too many,
+//! which phrases signal a change of topic. A second engine has no business
+//! holding an opinion on any of it, and the host that renders these segments to
+//! the user is the only thing that can tune them against what users actually
+//! see.
+//!
+//! The rest of the archivist's engine calls became the `Episodic` contract
+//! family, which persists what this module decides.
+//!
+//! # The thresholds are unchanged, deliberately
+//!
+//! Every value here — the ten-minute gap, the 0.4 similarity floor, the
+//! twenty-turn cap, the marker list, the 200-character bookends — is carried
+//! over verbatim from the engine. This is a move, not a retune: changing
+//! behaviour in the same step that changes where the behaviour lives would make
+//! any resulting regression impossible to attribute. Tune them afterwards,

+//! An in-memory [`MemoryProfile`] for the learning tests.
+//!
+//! # Why this exists rather than `#[ignore]`
+//!
+//! The learning tests used to build a real `ProfileStore` over an in-memory
+//! SQLite connection. That store moved behind the memory module, so those
+//! constructions no longer compile — and the obvious response, parking the
+//! tests on `OPENHUMAN_MODULE_PATH` like the tool tests, would have cost ~50
+//! tests of coverage for no gain.
+//!
+//! It would also have been the wrong trade. Those tests are about *learning*
+//! logic — stability scoring, class bucketing, prompt rendering, eviction — not
+//! about storage. They only ever needed somewhere to put facets. So this
+//! provides exactly that: a `HashMap` behind a mutex, implementing the same
+//! contract the driver does.
+//!
+//! # Not `#[cfg(test)]`, deliberately
+//!
+//! Integration tests under `tests/` link the library compiled *without*
+//! `cfg(test)`, so a test-gated helper is invisible to them — which is exactly
+//! how `tests/learning_phase4_integration_test.rs` was left uncompilable once
+//! before. `ProfileStore::for_tests` carries the same note and the same
+//! `#[doc(hidden)]` treatment for the same reason.
+//!
+//! # It mimics the engine's ordering, because the tests depend on it
+//!
+//! `list_active` and `list_all` sort by stability descending, which is what the
+//! engine's SQL does and what several assertions rely on. A fake that returned
+//! insertion order would pass its own tests and quietly diverge from the thing
+//! it stands in for.

+//! An in-memory [`MemoryProvider`] that actually stores things.
+//!
+//! # Why this exists
+//!
+//! The module port keeps meeting the same test problem. A consumer used to be
+//! handed an `Arc<dyn Memory>` and tests handed it a real `UnifiedMemory` over
+//! a temp dir, then asserted a genuine round trip: write, read back, prune.
+//! Converting the consumer to the guard breaks those tests, and the cheap
+//! answer — `#[ignore]` behind `OPENHUMAN_MODULE_PATH` — pays for each
+//! conversion with real coverage.
+//!
+//! [`super::test_support::RecordingProvider`] cannot stand in: it records calls
+//! and answers empty, which proves a call was *made* but never that the data
+//! came back. Round-trip assertions need storage.
+//!
+//! So this is storage: a `HashMap` keyed by `(namespace, key)` behind a mutex,
+//! implementing the mandatory three so it can be wrapped in a real
+//! [`MemoryGuard`](super::MemoryGuard) and dropped in wherever a consumer now
+//! wants a guard.
+//!
+//! # It is deliberately not `#[cfg(test)]`
+//!
+//! Integration tests under `tests/` link the library compiled without
+//! `cfg(test)`, so a test-gated helper is invisible to them — the trap
+//! `ProfileStore::for_tests` documents and this port has already fallen into
+//! once. `#[doc(hidden)]` keeps it off the public docs instead.
+//!
+//! # What it does not pretend to be
+//!
+//! `recall` is a substring match over content, not a ranked hybrid search. That
+//! is enough for "did the write land and come back", which is what these tests
+//! assert; it is **not** enough to test ranking, and a test about ordering
+//! should use the real engine rather than this.

+//! Two-lane explicit user preferences — namespaces, thresholds, read helpers.
+//!
+//! Preferences written by the `save_preference` tool live in one of two
+//! namespaces depending on their relevance scope:
+//!
+//! - [`USER_PREF_GENERAL_NAMESPACE`] — always-on; injected into the system
+//!   prompt at thread start (Lane A).
+//! - [`USER_PREF_SITUATIONAL_NAMESPACE`] — topic-scoped; recalled per-turn by
+//!   semantic similarity to the user's message (Lane B).
+//!
+//! Keeping the namespace constants and read helpers in one place lets the write
+//! path, the system-prompt builder, and the per-turn recall path share one
+//! definition.
+//!
+//! # Why this is host-side
+//!
+//! It used to live in the engine, and nothing about it was ever the engine's.
+//! Which namespaces the two lanes use, how many standing preferences a prompt
+//! may carry, how similar a hit must be before it counts as a contradiction —
+//! those are product decisions about what to put in front of a model. A second
+//! engine would have to reimplement them identically or the product would
+//! change underneath it.
+//!
+//! The move cost no capability. The engine's `recall_relevant_by_vector` was
+//! itself a *default* method over `query_namespace_hits`, filtering by the
+//! vector component of the score breakdown; the contract exposes exactly that
+//! query as [`MemoryRetrieval::recall_namespace_scored`], so the filter is
+//! reproduced here verbatim rather than being asked for over the bus.
+//!
+//! # A driver without retrieval yields no preferences, not an error
+//!
+//! [`recall_by_vector`] returns empty when the bound driver does not advertise
+//! [`Capability::Retrieval`](crate::openhuman::memory::api::capabilities::Capability::Retrieval).
+//! That preserves the engine's behaviour — its default returned empty so
+//! keyword-only backends opted out — and it is the right failure mode for both
+//! callers: an absent Lane-B block and an absent contradiction check are
+//! degradations, whereas an error would fail a chat turn or a preference write
+//! over a capability the operator chose not to have.

 //! summarisation, and read/write mechanics.
+//!
+//! # Everything here goes through the bound driver
+//!
+//! These were direct calls into `tinymemory_core::tree::retrieval`, which
+//! opened the workspace store in this process. They now resolve the guarded
+//! driver and use the `MemoryRetrieval` family, so the loaded module is the
+//! only reader — see `docs/specs/2026-08-13-memory-module-port.md` §2.1.
+//!
+//! `None` is passed for every `scope` argument, and that is not "unrestricted":
+//! the guard intersects it with the ambient per-turn allowlist before the call
+//! reaches the driver, so naming a scope here could only ever narrow what the
+//! turn may see.
