From 0eb2d006e486df8f8c387f622d924e96089583d6 Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Sun, 2 Aug 2026 16:23:55 +0300 Subject: [PATCH 001/112] feat(flows): advance tinyflows to v0.5.1 and gate unrunnable node kinds MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit tinyflows main moved 5 commits ahead of the pinned gitlink (declared workflow inputs, per-item fan-out, and the new memory + dedup node kinds). Three breakages fixed: - Capabilities gained a required memory field. Left None: a flow reaching user memory is policy-bearing (taint, source_scope, redaction on read; writes on remember/forget) and those guarantees live inside the memory domain today, so a raw adapter here would route flow traffic around them. Wiring waits on the kernel-side guard (docs/specs/kernel.md 3.4). - WorkflowGraph gained inputs; n8n import has no equivalent, so empty. - NodeKind match in flows::tools was non-exhaustive. Withhold memory and dedup from the advertised catalog rather than letting propose_workflow build graphs that cannot run here. dedup is the subtler one: the node only stages tentative keys and the crate leaves commit-on-success to the host, which OpenHuman does not yet do — so it would dedup within a run but never across runs, silently republishing. Absence beats a surface that returns a wrong answer. The count assertion in node_contracts is now derived from the crate catalog instead of hard-coded, so the next bump surfaces a new kind rather than failing on a stale 12. Also lands the Phase 0 trait-catalogue RFC gitlink for tinyagents and the kernel/agent-move specs.

It classifies the new logical message set against what was persisted: + pure extension → append the tail; reduction/rewrite → append a single + `{"kind":"compaction","replacement":[…]}` record carrying the full reduced + set, leaving earlier turns on disk. +2. **Two read paths from one log.** `read_transcript` replays for *model + context* (compaction records replace the accumulator; `interrupted:true` + partials are skipped). `read_transcript_display` returns **every** record in + file order so the UI can render pre-compaction history, compaction markers, + and interrupted partials. +3. **Rewrite-free cumulative meta.** A fresh `{"_meta":{…}}` line is appended + each turn; readers take the **last** `_meta` as authoritative, with line 1 as + a valid fallback for older cores. +4. **Forward/backward compatibility by construction.** `MessageLine` carries + `#[serde(flatten)] _extra`; `MetaPayload` does not set + `deny_unknown_fields`; `_meta.version` is `TRANSCRIPT_SCHEMA_VERSION`. Old + cores skip unknown-kind lines instead of crashing.

A +naive "just implement `ChatHistory`" that routes reads through `messages()` +would silently drop compaction and interrupted-partial semantics — i.e. corrupt +the model context on any compacted thread. This is the single most important +constraint in this document. + +--- + +## 3.5 Re-examined: `builder/factory.rs` and `turn/core.rs` + +The §2.2 verdict ("21 imports, therefore host") describes the *wiring*, not the +*shape*. A shape can be generic even when every value flowing through it is +product-specific, so both files were re-read rather than dismissed on the import +count. Result: **the structure is already in the crate; the residue is genuinely +product — with two concrete exceptions worth acting on.** + +### 3.5.1 `Agent` is not a duplicate of `AgentHarness` + +`AgentHarness` (`harness/runtime/types.rs:259`) has **six** fields — +`models`, `tools`, `middleware`, `policy`, `tool_timeouts`, `response_cache` — +and a complete builder API: `new`, `register_model`, `set_default_model`, +`register_tool`, `push_middleware`, `push_model_middleware`, +`push_tool_middleware`, `with_policy`, `with_tool_timeout_settings`, +`with_response_cache`. The seam already drives exactly this API +(`tinyagents/mod.rs:1793–2302`). + +The host `Agent` (`session/types.rs:31`) has **40+ fields**, and the ones that +define it are not execution config at all: + +- **Per-turn product accumulators:** `last_memory_context`, + `last_turn_citations`, `last_turn_usage_totals`, `last_turn_hit_cap` — read + by web-channel delivery to render citation chips, token/cost meters, and to + distinguish "paused at the iteration cap" from "asked a question". +- **Host service handles:** `memory`, `shared_experience_memory`, + `memory_loader`, `tool_policy_session`, `workflows`. +- **Product policy:** `learning_enabled`, `explicit_preferences_enabled`, + `subagent_tool_ceiling_names`, `visible_tool_names`. +- **Event identity:** `event_session_id`, `event_channel`. + +`Agent` is OpenHuman's **session-state + turn-result object**; `AgentHarness` is +the crate's execution configuration. They are different things that both happen +to hold tools and a model. That single overlap is already bridged by +`SharedToolAdapter`, which the WP-4 decision fixed as a permanent boundary. And +`Agent` already holds a crate type directly — `workspace_descriptor: +tinyagents::harness::workspace::WorkspaceDescriptor` — which is what convergence +looks like in practice: adopt crate types field by field, don't relocate the +struct. + +**So there are not two builders competing.** There are two builders in series +(host `Agent::from_config` → seam → crate `AgentHarness`), building two +different objects. Moving `factory.rs` down would require the crate to import +Composio, OpenHuman `SecurityPolicy`, `memory_store`, `skills`, `profiles`, and +`subconscious` — the exact GPL/crates.io boundary violation the port plan +forbids. + +### 3.5.2 `turn/core.rs` is preparation, and the engine already left + +WP-3 established that `turn/core.rs` "performs OpenHuman turn preparation and +calls the TinyAgents session path" — it contains no turn engine. Reading it +confirms that: `impl Agent` starts at line 432, and everything above it is +product gating. What `turn()` actually does before delegating: + +- super-context gating hard-wired to `orchestrator` + `context_scout`, with an + explicit carve-out so background/cron/specialist turns don't spawn it; +- agent-experience retrieval and `prepend_experience_block`; +- memory recall citation collection; +- integration / MCP / skill announcement + retraction notes. + +None of that is framework-shaped. **But ~150 LOC of it is:** +`tool_records_from_conversation`, `stamp_tool_failures`, `parse_tool_call_id`, +`short_failure_detail`, `replace_last_assistant_reply` are pure message-list +manipulation over roles and tool-call ids. Those are candidates for crate +`harness::message` helpers — small, but genuinely generic. + +### 3.5.3 The one real duplicate: dispatcher-kind resolution + +`resolve_dispatcher_kind` (`factory.rs:1398`) picks Native / Xml / PFormat from +`supports_native`, plus an `integrations_agent` override. The three +`ToolDispatcher` impls then render and parse tool calls accordingly. + +**The crate already makes this decision.** `OpenAiModel` exposes +`with_native_tool_calling(bool)` and internally computes +`prompt_guided_tools = !self.profile.tool_calling && !request.tools.is_empty()` +(`providers/openai/transport.rs:951`), replaying calls and results as text when +prompt-guided — that is #55. So OpenHuman decides native-vs-prompt-guided at the +session-build layer, and the crate decides it again at the model layer. + +This is the **same subsystem** as the parent spec's DS-5b (`harness/parse.rs` +duplicating #55/#57 parsing). Dispatcher selection, tool-call rendering, and +tool-call parsing are one concern split across two layers and two owners. They +should be resolved together, and the answer is almost certainly: the crate owns +the native-vs-prompt-guided decision and both directions of the wire format; +OpenHuman keeps only the `integrations_agent` override as an explicit policy +input, and the durable `to_provider_messages` serialization. + +### 3.5.4 The generalizable conclusion + +The productive question is not *"which file moves down"* but *"which extension +point is missing upstream"*. `factory.rs` and `turn/core.rs` are large because +the crate offers registries and middleware but no typed **turn-preparation** +seam — so every product enrichment (experience, citations, announcements, +super-context) is hand-written into one `turn()` body instead of registered. + +If the crate grew a `ContextEnricher` / `TurnPreparation` pipeline — +ordered, fallible, each returning prompt fragments plus metadata — OpenHuman's +enrichment becomes registrations rather than a bespoke method, and the *shape* +moves down while the *wiring* stays up. That is worth designing (S6), and it is +what "enrich it as a library" should mean here. It is explicitly **not** a +licence to relocate 3,900 lines of host wiring. + +--- + +## 4. The decision (§4 is the gate — pick one before writing code) + +### Option A — Host backend behind the crate trait *(recommended)* + +Keep `ChatMessage`, the `session_raw` format, and every host-only helper exactly +as they are. Add `impl tinyagents::harness::memory::ChatHistory for +SessionTranscriptHistory`, converting at the boundary via the existing +`agent/message_convert.rs`. The harness talks to the crate trait; OpenHuman owns +the format. Host-only semantics (display read, compaction markers, usage +rollups, path resolution) stay on the concrete type, reached directly by the 24 +consumers that need them. + +- **On-disk change:** none. **Migration risk:** none. +- **Removes:** ~400 LOC of parallel abstraction, plus the conceptual duplicate. +- **Cost:** low. Reversible. +- **Weakness:** the crate trait is only used on the narrow runtime path; most of + `transcript.rs` stays. Honest framing: this fixes *"two abstractions"*, not + *"two implementations"*. + +### Option B — Upstream a generic append-only history backend + +Add `JsonlChatHistory` to the crate beside `StoreChatHistory`, and extend +`ChatHistory` (or add a `ReplayableChatHistory` supertrait) with the three +missing generic semantics: compaction-replacement records, skippable partials, +and a display-order read. `ChatMessage`'s durable fields survive as crate +`Message` + a `raw` passthrough, mirroring how the tool-model decision preserves +`ToolResult::raw`. + +- **Removes:** ~2,100 host LOC. +- **Cost:** high — a trait extension in a published GPL crate, a durable format + becoming public API, and an on-disk parity soak. +- **Only justified if** a second host will use it. Compaction-aware append-only + transcripts are genuinely generic agent-framework machinery, so this is + defensible — but it is a crate-roadmap decision, not a cleanup. + +### Option C — Declare host-owned, close the question + +Record `transcript.rs` in the deletion ledger as HOST-OWNED (durable on-disk +format + product read paths), same disposition as `tool_status` and +`namespace_store`. Costs nothing, keeps two abstractions. + +**Recommendation: A now, B only if the crate roadmap wants a durable transcript +primitive.** A is cheap, reversible, and removes the thing that actually +confuses readers. B should not be smuggled in as refactoring. + +--- + +## 5. Plan (Option A) + +Every slice: failing-before/passing-after test, small validated commit on a +feature branch, `atomic-commit` with explicit paths. + +### S0 — Ledger + decision record (no code) + +Add a ledger row for `harness/session/` recording the §2.2 split and the §4 +choice. Without this, a future audit re-opens "why didn't session move?" — which +has already happened twice in this migration. + +**Exit:** row present; this doc linked from the parent spec's DS-8. + +### S1 — `migration.rs` disposition + +Zero host imports, but it migrates *OpenHuman's* directory layout +(`session_raw/DDMMYYYY/` → flat). Generic code for a host-specific format. + +Expected outcome: **stays host**, recorded with that reason. Do the 10-minute +check rather than assuming; if it turns out to be a general "flatten a +date-bucketed log dir" utility with no OpenHuman naming, it can go down. + +**Exit:** one ledger row, either way. + +### S2 — Extract the trait-shaped surface + +Introduce `SessionTranscriptHistory { workspace_dir, stem }` in +`session/transcript_history.rs`, wrapping the existing free functions. No +behaviour change; purely a handle where a trait impl can live. + +**Exit:** `cargo check` + existing `transcript_tests.rs` green, untouched. + +### S3 — Implement crate `ChatHistory` + +```rust +impl tinyagents::harness::memory::ChatHistory for SessionTranscriptHistory { + async fn messages(&self, thread_id: &str) -> Result>; // read_transcript (model-context replay) → message_convert + async fn append(&self, thread_id: &str, message: Message) -> Result<()>; + async fn replace(&self, thread_id: &str, messages: Vec) -> Result<()>; + async fn clear(&self, thread_id: &str) -> Result<()>; +} +``` + +Hard requirements, each with its own test: + +- `messages()` MUST route through the **model-context** replay path, so + compaction records replace the accumulator and `interrupted` partials are + skipped. A test must construct a compacted transcript and assert + `messages()` == `read_transcript()`, not the raw line set. +- `replace()` MUST map onto the compaction-record path + (`append_transcript_turn`'s reduction branch), **not** a file rewrite. The + append-only invariant is the format's core property; a trait default that + clears-then-appends would destroy history. +- `clear()` semantics must be decided explicitly — truncate vs. start a new + stem. Whichever, write it in the doc comment. + +**Exit:** compaction and interrupted-partial round-trip tests green; the +byte-identity assertion against the pre-change reader passes. + +### S4 — Route the harness through the trait + +The turn path takes `Arc` instead of calling transcript free +functions. The 24 consumers that need display records, usage rollups, or path +resolution keep using the concrete type — that is correct, not debt. + +**Exit:** `agent_harness_e2e` + `scripts/test-rust-with-mock.sh` green; +`threads/transcript_view` projection output unchanged (golden test). + +### S5 — Shadow soak, then remove the parallel path + +One release with both paths live and a read-side comparison logged on mismatch +(never panic — a mismatch on a user's real transcript must degrade, not crash). +Then delete the redundant abstraction and update the ledger. + +**Exit:** ledger row terminal; `docs/` transcript-derived-view note restated in +terms of the crate trait. + +--- + +### S6 — Follow-ups from the §3.5 re-examination + +Independent of S0–S5; each is separately shippable and none requires the +transcript decision. + +1. **Unify dispatcher selection with the model layer** (§3.5.3). Merge with the + parent spec's DS-5b — dispatcher choice, tool-call rendering, and tool-call + parsing are one concern. Deliverable: the crate owns native-vs-prompt-guided; + OpenHuman passes the `integrations_agent` override as policy and keeps + `to_provider_messages` for the durable envelope. Est. host LOC removed when + combined with DS-5b: **~2,400**. +2. **Upstream the message-list helpers** (§3.5.2): `tool_records_from_conversation`, + `stamp_tool_failures`, `parse_tool_call_id`, `short_failure_detail`, + `replace_last_assistant_reply` → crate `harness::message`. ~150 LOC. Small, + uncontroversial, do it alongside DS-5b's parity-test port. +3. **Design a crate turn-preparation seam** (§3.5.4). A `ContextEnricher` / + `TurnPreparation` pipeline — ordered, fallible, returning prompt fragments + + metadata — so product enrichment registers instead of being hand-written into + `turn()`. This is a **crate roadmap proposal, not a refactor**: write the + design, get it accepted upstream, then migrate OpenHuman's four enrichers + (super-context, agent-experience, recall citations, announcements) onto it. + Do not start by moving code. +4. **Continue adopting crate types field-by-field on `Agent`**, following the + `workspace_descriptor: tinyagents::harness::workspace::WorkspaceDescriptor` + precedent. This is how `Agent` converges without ever relocating — record + each adopted field in the ledger. + +**Exit:** items 1–2 landed; item 3 is an accepted-or-rejected upstream design +doc, not an open question; item 4 has a standing ledger section. + +## 6. Explicitly out of scope + +Recorded so a later audit does not re-litigate: + +- `builder/` (1,699 + 666 + 96 + 55) — 21-domain host wiring, and it builds a + *different object* than the crate's `AgentHarness` (§3.5.1). **Permanent + host**, minus the dispatcher-selection carve-out in S6.1. +- `turn/core.rs`, `turn/tools.rs`, `turn/context.rs`, `turn/session_io.rs`, + `turn/mod.rs`, `turn/graph.rs` — product turn preparation; the engine already + left in WP-3 (§3.5.2). **Permanent host**, minus the ~150 LOC of message-list + helpers in S6.2 and whatever S6.3's preparation seam later absorbs. +- `runtime.rs`, `types.rs` — `AgentSession` is a bag of host handles. **Permanent host.** +- `tool_progress.rs` (256) — already the C4 Step-5 deletion target; belongs to + the progress-tracing workstream (parent spec DS-5), not here. +- `ChatMessage` itself — WP-1 settled this: it is the versioned on-disk record, + and replacing it with crate `Message` changes existing users' data. Under + Option A it does not move. Only Option B reopens it. + +--- + +## 7. Risks + +- **Silent model-context corruption is the top risk.** If `messages()` is wired + to the display read path (or to a naive line replay), every compacted thread + feeds the model duplicated pre-compaction history. It will not throw; it will + degrade answers and inflate token cost. S3's compaction test is the gate. +- **`replace()`'s trait default is dangerous here.** The crate's default clears + then re-appends, which the crate's own docs flag as non-atomic. Against an + append-only durable log it is worse than non-atomic — it is destructive. + Override it; never inherit it. +- **On-disk compatibility.** Existing installs have live `session_raw` files, + including legacy `DDMMYYYY/` dirs. Resume must keep working across the change; + the `read_transcript_legacy_md` path and the flat/dated fallback both need + coverage in the soak. +- **Blast radius beyond `agent/`.** 24 files across `threads`, `session_import`, + `learning`, `migrations`. The `threads/turn_state` derived-view contract is + the fragile one. +- **≥ 80% diff-coverage merge gate.** S2/S4 touch many call sites; check + `diff-cover` locally before pushing rather than discovering it in CI. +- **Two Cargo worlds** — any vendored bump (only under Option B) regenerates + root **and** `app/src-tauri` lockfiles. +- **`GGML_NATIVE=OFF`** for local root-crate `cargo` runs on Apple Silicon. +- **GPL/crates.io boundary** — under Option B, the `session_raw` format becomes + public API of a redistributed crate. Nothing product-specific (agent ids, + OpenHuman path conventions, `.md` rendering) may cross. + +--- + +## 8.

The host keeps only what a + Supermemory-only build would still need: RPC, agent tools, policy, credentials, scheduling, + registry, adapters. +3. **No behaviour change for the default build.** Bind `tinycortex`, and the RPC surface, agent + tools, on-disk workspace, and parity harness are byte-identical to today. + +## 2. Where we are + +- 74k LOC across `memory` (18.3k), `memory_store` (17.4k), `memory_sync` (17.2k), `memory_tree` + (9.9k), `memory_sources` (5.0k), `memory_diff` (2.0k), `memory_queue` (1.4k), `memory_tools` + (1.3k), `memory_goals` (0.9k), `memory_conversations` (0.9k), `memory_search` (0.7k), plus a + 3.2k-LOC seam at `src/openhuman/tinycortex/`. +- The engine cutover is **complete**: TinyCortex is already the implementation authority for + chunks, content, vectors, trees, retrieval, scoring, queue, ingest, readers, sync, diffs, goals, + graph, conversations, and tool memory. +- But the coupling is **static and direct**. `memory::traits` is a `pub use tinycortex::memory::{…}`; + `memory/global.rs` hands out a concrete `MemoryClient`; `UnifiedMemory` (the ten-table + namespace-document tier) is host-owned SQLite. There is no seam a second backend can enter, and + ~51 controller schemas assume the full capability set is present. + +### What OpenClaw does, and what we take from it + +OpenClaw's memory is a **single slot** (`plugins.slots.memory`) with a local default (Markdown + +sqlite-vec + FTS5 hybrid). Installing `memory-lancedb` or `@mem0/openclaw-mem0` claims the slot and +disables the incumbent with a warning. Providers expose a small tool triple — +`memory_recall` / `memory_store` / `memory_forget` — plus opt-in **auto-recall before the turn** +and **auto-capture after the turn**, bounded by `recallMaxChars` / `captureMaxChars` and a context +token budget. Ownership isolation is a storage predicate, not a post-search filter. + +**Adopt:** one-slot binding; the recall/store/forget core triple; auto-recall/auto-capture as +kernel-owned lifecycle hooks; per-call character/token budgets; isolation pushed into the query. +**Reject:** the tool triple as the *whole* contract — OpenHuman's surface is an order of magnitude +larger (trees, diffs, goals, sources, sync, entities), which is exactly why capabilities must be +negotiated rather than assumed. **Also reject:** provider-authored lifecycle hooks. In OpenClaw the +plugin hooks the turn; here the kernel does, so policy cannot be bypassed by a driver. + +--- + +## 3. The contract: `tinycortex-api` + +### 3.1 Crate carve-out (the enabling move) + +Today the shared value types live in `tinycortex::memory`, so any driver depending on the contract +drags in SQLite, the retrieval engine, and the job model.

Both-ways tests per family, mirroring `channels_controllers_{registered,absent}`. + +### 3.4 The guard (non-negotiable) + +`MemoryGuard` wraps the bound driver and is the only handle product code ever +receives. It enforces, in order: + +1. `SecurityPolicy` tier + workspace/action-root path rules; +2. `source_scope` per-turn allowlist — **applied as a query predicate passed to the driver**, not + as a post-filter (OpenClaw's isolation lesson; also what today's W5 seam test pins); +3. `MemoryTaint` stamping on every write — the driver receives taint, never assigns it; +4. redaction (`memory/util/redact.rs`) on content leaving the process for an `external` driver; +5. egress budget + `trust_state` check for `external` drivers; +6. char/token budgets for auto-recall/auto-capture; +7. audit event on the bus + tracing span with `driver_id`, `capability`, `namespace`. + +Steps 4–5 are new and exist because "memory" is the most sensitive data in the product. An +`external` driver bind requires an explicit `trust_state = "trusted"` and, on first bind, a +one-time user consent recorded in config. Fail-closed: unset trust ⇒ refuse to bind, fall back to +embedded, surface in status. + +### 3.5 Lifecycle hooks (kernel-owned) + +- **auto-recall** — before an interactive turn, the kernel calls `recall` and injects results + under a `max_context_tokens` budget (default 2000, OpenClaw parity). +- **auto-capture** — after a turn, the kernel decides *whether* to capture (existing + `remember.rs` / `preferences.rs` policy) and calls `store`. +- **maintenance tick** — the existing scheduler drives `MemoryMaintenance::consolidate` if + advertised; the embedded driver maps it to seal/cascade/reembed. + +Drivers do not hook the agent loop. Same rule as `queue::run_once`: the host owns the loop, the +engine owns one step. + +--- + +## 4. Drivers + +### 4.1 `tinycortex` — embedded default + +`src/openhuman/memory_adapter/embedded/` implements every family over the existing seam +(`src/openhuman/tinycortex/`). Zero new engine logic: it is a re-shaping of the current direct +calls into contract methods. Advertises all 13 families. This is the compatibility anchor — the +parity harness compares it against pre-change behaviour. + +### 4.2 `http` — the external transport adapter + +`src/openhuman/memory_adapter/http/` implements every family by translating to a documented +JSON wire contract, so a third-party backend never depends on Rust or on this repo: + +``` +POST /v1/handshake → { contract_version, driver_id, capabilities[] } +POST /v1/memory/store { namespace, key, content, category, taint, session_id } +POST /v1/memory/recall { query, namespace, limit, filters, scope_allowlist[] } → ranked[] +POST /v1/memory/forget { namespace, key | query } +POST /v1/memory/ingest { source_ref, content, mime, taint } +GET /v1/memory/export → NDJSON stream +POST /v1/memory/import ← NDJSON stream +GET /v1/health → { status, detail } +``` + +Unsupported family ⇒ the endpoint is absent from `capabilities[]` and returns `501`; the adapter +maps that to `MemoryError::Unsupported`. Auth via a keychain-resolved bearer. The handshake pins +the contract version; a major mismatch refuses the bind. + +**`supermemory` reference driver** is a thin config profile over `http` (base URL, auth, field +mapping), shipped as a worked example plus a conformance-suite run — not special-cased in code. + +### 4.3 `mcp` — opportunistic + +For backends that already speak MCP, an adapter maps the families onto MCP tool calls through the +existing `mcp_client`. Lower priority; `http` covers the demand. + +### 4.4 `composite` / `mirror` + +Per kernel spec §3.5. `mirror` is the **migration path**: bind +`mirror { primary = "tinycortex", secondary = "supermemory" }`, backfill via +`export`→`import`, verify with the conformance suite, then re-bind to the secondary. + +### 4.5 Config + +```toml +[subsystems.memory] +driver = "tinycortex" + +[subsystems.memory.hooks] +auto_recall = true +auto_capture = true +max_context_tokens = 2000 +recall_max_chars = 1000 +capture_max_chars = 500 + +[subsystems.memory.drivers.supermemory] +class = "external"; transport = "http" +endpoint = "https://api.supermemory.ai" +credential_ref = "keychain:supermemory" +trust_state = "untrusted" # must be explicitly raised before bind succeeds +``` + +The existing `[memory]`, `[memory_tree]`, `[[memory_sources]]` blocks stay as-is and map into the +embedded driver's options; no user-visible config break. + +--- + +## 5. RPC & tools (unchanged surface) + +Method names, params, and payloads are **unchanged** — `memory*`, `memory_tree*`, `memory_sync*`, +`memory_sources*`, `memory_diff*`, `memory_goals*` all keep their contracts. Handlers stop calling +`memory::global::client()` and call `memory::subsystem::guard()` instead. Two additions: + +- `memory_provider_status` — bound driver id, class, health, contract version, capabilities, + last error. Drives the UI's capability-aware rendering. +- `memory_export` / `memory_import` — provider-agnostic NDJSON portability, gated by the approval + gate (a full memory export is a high-consequence action). + +--- + +## 6. Consolidation: what moves into TinyCortex + +### 6.1 Re-disposition vs. the 2026-07-28 cutover evaluation + +That evaluation asked *"is this product policy or engine logic?"* and concluded the remaining +`memory*` modules must stay. Under the kernel criterion (kernel spec §4) the question becomes +*"would a Supermemory-only build still need this file?"* — and several modules it retained are +**implementation of the default driver**, which is exactly where they belong once a second driver +is possible. Its core warning still holds and is honoured here: RPC, policy, secrets, and runtime +composition must **not** move into the crate. + +### 6.2 Moves to `vendor/tinycortex` + +| Host module | Why it moves | Lands as | +| --- | --- | --- | +| `memory_store/namespace_store/*` (the ten-table tier: `memory_docs`, `graph_*`, `episodic_log`+fts, `event_log`+fts+embeddings, `conversation_segments`, `segment_embeddings`, `vector_chunks`, `user_profile`) | TinyCortex-specific SQLite schema + migrations.

Inventory: + +**(a) Task-local `source_scope` read from inside retrieval — the security-relevant one.** +`memory_tree/retrieval/{source,fast,drill_down,fetch,cover}.rs` call +`memory::source_scope::current_source_scope()` / `chunk_source_allowed_in()` directly. The +per-turn allowlist is a *host task-local* consumed *inside the engine*. Moving these files as-is +either drags `source_scope` into the crate (policy in the engine — the failure mode the +2026-07-28 cutover evaluation correctly warned about) or silently drops the allowlist. +**Fix:** invert it — retrieval takes an explicit `scope: Option<&ScopePredicate>` parameter, and +`MemoryGuard` populates it from the task-local at the call boundary. This is already the spec's +stated design (§3.4 step 2: *applied as a query predicate passed to the driver, not as a +post-filter*); it just has to land **before** the move, not after. Mechanical: five call sites, +one signature. +*(`memory_store/tools/raw_chunks.rs`, `memory_search/tools/{chunk_context,vector_search}.rs` also +read the task-local, but those are agent tools — kernel-side, staying put. No change needed.)* + +**(b) Config/event-bus reach-backs from `memory_tree`.** ~20 files under `memory_tree/{tree,score, +graph,health,retrieval}` import `crate::openhuman::config::` or `crate::core::event_bus`. +**Fix:** pass the derived options in (the `MemoryConfig` mapping the seam's `config.rs` already +does) and emit through the existing sink traits instead of the bus directly. Mechanical, but +broader than (a) — this is the bulk of `memory_tree`'s move cost. + +**Already fine, no work needed:** `memory_store/safety/*` is already a thin shim over the crate +scrubber; `namespace_store/query.rs` only *constructs* `MemoryTaint::Internal` (a type, which M0 +puts in `tinycortex-api`); `memory_sources/readers/*` only mention redaction in log comments. + +**Consequence for sequencing:** the M4-before-M8 rule is sharper than "all policy first". Only +class (a) is a policy-correctness gate. Class (b) is a decoupling chore that can run per-module in +parallel. So the move can start earlier and wider than the linear workstream table implies — +see the revised M8 split in §8. + +### 6.6 The shims must stay host-owned + +"Shims to expose the RPC APIs" has two possible shapes, and only one is correct: + +- ✅ **Host-owned thin controllers over the contract.** `memory/schemas/*.rs` keeps defining the + schema, keeps `handle_*` delegating — but delegates to `MemoryGuard` instead + of a concrete TinyCortex path. The crate never learns that JSON-RPC exists. +- ❌ **Crate-owned RPC exposed through a host shim.** If `tinycortex` gains schemas/handlers and + the host merely re-exports them, the dependency boundary inverts: the reusable engine now knows + OpenHuman's method names, error envelope, and policy vocabulary — and a second driver can no + longer satisfy the same RPC surface, which defeats the whole point. + +The 51 controller schemas under `memory/schemas/` therefore **do not move**, even though they are +thin. Thin is what a good syscall table looks like. + +### 6.7 Expected shape after + +~74k LOC of host `memory*` reduces to a kernel-side surface dominated by RPC + tools + policy + +adapters. **Line count is not the goal and not the success metric** — the metric is that +`grep -rn "tinycortex::" src/openhuman/ --include=*.rs` returns hits only under +`memory_adapter/embedded/` and `src/openhuman/tinycortex/`. + +--- + +## 7.

Today it is closer to a +monolith with one very good in-tree implementation per capability: memory *is* TinyCortex, agents +*are* TinyAgents, channels *are* TinyChannels. Each already has a seam (`src/openhuman/tinycortex/`, +`src/openhuman/tinyagents/`), which proves the shape works — but the seams are **bespoke per +domain**, the contracts are **not versioned**, and there is **no way for a third implementation to +be bound at runtime**. + +This spec defines the general model.

Model + +### 3.1 Definitions + +- **Kernel** — `src/core/` plus the always-on platform domains. Owns: RPC transport and the + controller registry, the event bus, config load/validation, `SecurityPolicy` and the approval + gate, scheduling/cron, the workspace and path roots, observability, and the subsystem registry. + The kernel contains **no capability implementation**. +- **Subsystem** — a named capability slot: `memory`, `inference`, `channels`, `skills`, `flows`, + `sandbox`, `voice`. Each subsystem owns a **contract** (a set of Rust traits + value types), a + **config section**, a **stable RPC namespace**, and an **agent-tool family**. +- **Driver** — an implementation of a subsystem contract. Three classes: + - **`embedded`** — an in-tree/vendored Rust crate (`tinycortex`, `tinyagents`, `tinychannels`). + The default; no network, no extra process. + - **`external`** — an out-of-process backend reached through a transport adapter over a + documented wire contract (HTTP/JSON, or MCP). This is how a third party ships a driver + without touching this repo. + - **`null`** — a stub advertising zero capabilities. What a compiled-out or unconfigured + subsystem binds to. Replaces today's hand-written `stub.rs` files with one generic answer. +- **Binding** — exactly **one** driver is bound per subsystem per process, chosen by config at + boot. Same rule OpenClaw uses for `plugins.slots.memory`: installing a second memory backend + disables the first with a warning, because two live memory backends means two truths. Fan-out + across several backends is expressed as a **composite driver** (§3.5), not as a second binding. + +### 3.2 The contract shape (normative) + +Every subsystem contract is defined in an **API module with no engine dependencies** and follows +the same five-part shape: + +```rust +// 1. Identity + lifecycle — every driver implements this. +#[async_trait] +pub trait Driver: Send + Sync + 'static { + fn id(&self) -> &str; // "tinycortex", "supermemory", "null" + fn class(&self) -> DriverClass; // Embedded | External | Null + fn capabilities(&self) -> Capabilities; // 2. + async fn health(&self) -> DriverHealth; // Ready | Degraded { reason } | Down { reason } + async fn shutdown(&self) -> Result<()>; +} + +// 2. Capability descriptor — a bitset/struct of optional trait families, not a version number. +// 3. Capability traits — one per family; a driver implements only what it advertises. +// 4. Value types — serde-only, dependency-free, shared by every driver. +// 5. Errors — a typed enum with a mandatory `Unsupported { capability }` variant. +``` + +**Rules:** + +1. **Capabilities are negotiated, not assumed.** The kernel asks `capabilities()` once at bind + time and caches it. Calling an unadvertised capability is a kernel bug, not a driver error. +2. **Value types are inert.** Serde/std only — no SQLite, no tokio-specific types, no engine + types. This is the same carve-out rule the `skills` and `mcp` Cargo gates already follow + (`AGENTS.md`: *"put a domain's inert types in a dep-free submodule and leave it ungated"*), now + applied across crate boundaries so an external driver can depend on the API without pulling + the embedded engine. +3. **Drivers never see kernel concerns.** No RPC schemas, no `SecurityPolicy`, no keychain, no + event bus, no `Config`. Everything a driver needs is passed in its constructor or per call. +4. **Contracts are versioned.** Each API module carries `pub const CONTRACT_VERSION: (u16, u16)`. + Minor bump = capability added; major bump = existing signature changed. External drivers + report the version they speak in their handshake; a major mismatch fails the bind. + +### 3.3 Degradation is a first-class outcome + +When a bound driver does not advertise a capability, the kernel does **not** register a handler +that returns "not implemented". It behaves exactly like today's compile-time gates: + +- the corresponding **RPC methods are unregistered** — unknown-method over `/rpc`, absent from + `/schema`; +- the corresponding **agent tools are absent** from the tool list, not present-and-failing; +- the **UI** reads the capability set from `_status` and hides the surface. + +Absence beats a stub that errors. A registered-but-failing method teaches the model that the +capability exists and makes it retry (the exact reasoning already recorded for the `flows` gate). +The one exception is the **CLI**, which keeps its subcommand arm and reports a *build/config fact* +("memory driver `supermemory` does not support tree summarisation") — same reasoning as the +retained `mcp` and `tui` CLI arms. + +### 3.4 Policy is kernel-side and non-bypassable + +Every subsystem call from product code goes through a kernel-owned **guard decorator**, never to +the driver directly: + +``` +agent tool / RPC handler + │ + ▼ + Guard ── SecurityPolicy · taint stamping · scope allowlist · redaction · + │ egress budget · approval gate · audit event · tracing span + ▼ + bound driver D +``` + +`Guard` implements the same contract traits as `D`, so it is transparent to callers and +impossible to skip by construction. This closes the single largest risk of a driver model: today +`MemoryTaint`, `source_scope`, and redaction are enforced *inside* the memory domain, so a +replacement implementation would silently drop them. After this change a driver **cannot** see +un-redacted content it was not granted, and cannot stamp its own provenance. + +**External drivers additionally require:** a `CapabilityProviderConfig` entry with an explicit +`trust_state` (fail-closed `untrusted`), a recorded egress decision, and per-call budget +accounting. Sending user memory to a hosted backend is an egress event and is treated as one. + +### 3.5 Composition instead of kernel special-cases + +Multi-backend behaviour is expressed as drivers that wrap drivers: + +- **`composite`** — fan out reads across N drivers, merge/rank, write to a designated primary. +- **`mirror`** — write to both, read from primary; the migration path between backends. +- **`cache`** — embedded driver in front of an external one. + +Each is just another `Driver`, so the kernel keeps exactly one bind and zero special cases. + +### 3.6 Config shape (uniform across subsystems) + +```toml +[subsystems.memory] +driver = "tinycortex" # the bound slot; "null" disables + +[subsystems.memory.drivers.tinycortex] +# embedded driver options + +[subsystems.memory.drivers.supermemory] +class = "external" +transport = "http" +endpoint = "https://…" +credential_ref = "keychain:supermemory" # never an inline secret +``` + +Secrets are **references**, resolved kernel-side through the existing keychain, and passed to the +driver as a redacted `SecretString` — the pattern already pinned for Composio credentials. + +### 3.7 Runtime axes (unchanged, now three) + +| Axis | Question | Mechanism | +| --- | --- | --- | +| Compile-time | Is this code in the binary? | Cargo `[features]` | +| Runtime composition | Does this domain run this process? | `DomainSet` / `ServiceSet` | +| **Binding (new)** | **Which implementation answers?** | **subsystem registry + config** | + +They compose: a subsystem compiled out binds `null`; a subsystem gated off by `DomainSet` is not +bound at all; a subsystem present and enabled binds the configured driver, falling back to the +embedded default if that driver fails to construct (logged loudly, surfaced in status, never +silent). + +> **Feature-forwarding gate applies.** Any new default-ON gate (e.g. `memory-embedded`) must be +> added to `app/src-tauri/Cargo.toml`'s explicit feature list — the shell sets +> `default-features = false`. `scripts/ci/check-feature-forwarding.mjs` enforces this; the `voice` +> and `tokenjuice-treesitter` incidents are why. + +--- + +## 4.

A generic runtime cannot import OpenHuman's config +schema. Options: + +- **A — Crate-owned config structs.** The crate defines `SessionConfig`, + `TurnConfig`, `ToolConfig`; OpenHuman maps its schema into them at build time. + Explicit, versionable, and mirrors how `MemoryConfig` is derived for TinyCortex + (`tinycortex/config.rs::memory_config_from`). **Recommended.** +- **B — `ConfigProvider` trait** with ~40 getters. Avoids a mapping layer but + turns every config read into a virtual call and makes the trait a dumping + ground. +- **C — Generic `State` carries config.** Least code, worst discoverability; + every crate-side read needs a bound. + +Pick A. It is the pattern the org already uses successfully one crate over. + +### 4.2 `ChatMessage` and the transcript format + +Moving the session runtime down forces the transcript decision to **Option B** +of the transcript spec: the `session_raw` JSONL format becomes crate-owned +public API, and `ChatMessage`'s durable fields must survive as crate `Message` + +a `raw` passthrough (the `ToolResult::raw` precedent). This is the change with +real user-visible risk — existing installs have live transcripts and resume must +keep working. Phase 2 exists solely to de-risk it. + +--- + +## 5. Phased plan + +Each phase is independently valuable and leaves the tree green. Stop-anywhere is +a hard requirement, not a nicety. + +**Phase 0 — Ledger + trait catalogue (no code).** — *in progress (2026-08-02)* +Reopen the superseded rows (§ header). Write the ~10 trait signatures as an +upstream RFC in `vendor/tinyagents/docs/`. Nothing moves until the trait +catalogue is accepted upstream — otherwise the first mover defines the seams by +accident. +*Exit:* accepted RFC; ledger rows reopened. + +Draft landed: [`vendor/tinyagents/docs/spec/host-capability-traits-rfc.md`](../../vendor/tinyagents/docs/spec/host-capability-traits-rfc.md) +— all ten signatures, grounded in measured reference counts. **Not yet +accepted**; it carries four open questions that block Phase 1, the hard one +being a name collision: `tinyflows` 0.5.1 shipped its own, unrelated +`MemoryProvider` trait, and both crates are in OpenHuman's dependency graph. + +**Phase 1 — Land the traits upstream, empty.** +Add the traits + no-op/in-memory default impls to the crate. No host change. +*Exit:* crate `cargo test --all-features` green; version bump; both lockfiles. + +**Phase 2 — Transcript to crate `JsonlChatHistory` (transcript spec Option B).** +Do this early and alone: it is the only phase with on-disk risk. One release of +shadow-read parity, mismatch logged never panicked, legacy `DDMMYYYY/` and +`read_transcript_legacy_md` paths covered. +*Exit:* resume works across upgrade on a real workspace; parity soak clean. + +**Phase 3 — Config mapping (§4.1 Option A).** +Introduce crate config structs + a host `session_config_from(&Config)` mapper. +Repoint `agent/` internals to the crate structs *in place*, before moving. +*Exit:* zero `crate::openhuman::config::` references inside the code slated to +move. + +**Phase 4 — Implement the traits host-side, still in place.** +`MemoryProvider`, `ContextComposer`, `SecurityGate`, `BudgetGate`, +`DefinitionRegistry`, `ExperienceStore`, `LearningSink`, `ProgressSink`, +`ToolOutcomeClassifier`, `ModelResolver`. `agent/` calls them instead of +reaching into domains directly. **This phase delivers most of the architectural +value with none of the relocation risk** — after it, `agent/`'s outbound +coupling is ~10 traits instead of 45 domains, and the program can legitimately +stop here. +*Exit:* `grep -c "crate::openhuman::" src/openhuman/agent/harness/session/` down +from ~2,000 refs to the adapter layer only. + +**Phase 5 — Relocate, module family at a time.** +Order by inbound coupling, lowest first: `artifact_offload` → `run_queue` → +`parse`/`tool_calling` (merges with DS-5b) → `subagent_runner` → `session/turn` +→ `session/{builder,runtime,types}`. Each family: move to +`vendor/tinyagents/src/harness/`, re-export from the host adapter for one +release, then repoint consumers. +*Exit per family:* crate tests green; host `cargo check` both worlds; the +family's tests live upstream. + +**Phase 6 — Collapse the seam and the adapter.** +`src/openhuman/tinyagents/` dissolves into the host adapter layer. Delete the +compatibility re-exports. +*Exit:* `agent/` is the adapter layer only; parent spec's DS-0 re-export gate +allowlist is seam-free. + +**Phase 7 — Exit gate.** +Full `scripts/test-rust-with-mock.sh`, `cargo test --all-features` in both +vendored crates, slim disabled build **and** `cargo test --lib +--no-default-features --features tokenjuice-treesitter core::`, `pnpm +rust:check`, deletion-ledger totals reconciled, architecture docs rewritten. + +--- + +## 6. Risks + +- **Inbound coupling is the real cost, not outbound.** 48 domains import + `agent::`. Phase 5's per-family re-export window is what keeps that tractable; + skipping it turns every family move into a 48-domain atomic commit. +- **On-disk transcript risk (Phase 2)** is the only user-visible data risk in + the program. It is deliberately isolated and sequenced first. +- **`AgentProgress` is a UI contract.** It stays host-side and is produced + through `ProgressSink`. If it drifts into the crate, the frontend timeline, + cost footer, and citation chips break in ways unit tests will not catch. +- **Trait-explosion.** Ten traits is the budget. If Phase 4 needs a fifteenth, + that is a signal a seam is wrong — re-open the RFC rather than adding it. +- **GPL/crates.io.** Publishable: traits, generic loop, tool-calling wire + formats. Not publishable: `provider_role_for`'s `subconscious` routing, the + `integrations_agent` override, OpenHuman prompt text, backend phrasing, key + material. Every relocated file needs this check. +- **≥ 80% diff-coverage gate** on a program of this size — Phases 4 and 5 touch + hundreds of files.

There is no seam a second backend can enter, and + ~51 controller schemas assume the full capability set is present. + +### What OpenClaw does, and what we take from it + +OpenClaw's memory is a **single slot** (`plugins.slots.memory`) with a local default (Markdown + +sqlite-vec + FTS5 hybrid). Installing `memory-lancedb` or `@mem0/openclaw-mem0` claims the slot and +disables the incumbent with a warning. Providers expose a small tool triple — +`memory_recall` / `memory_store` / `memory_forget` — plus opt-in **auto-recall before the turn** +and **auto-capture after the turn**, bounded by `recallMaxChars` / `captureMaxChars` and a context +token budget. Ownership isolation is a storage predicate, not a post-search filter. + +**Adopt:** one-slot binding; the recall/store/forget core triple; auto-recall/auto-capture as +kernel-owned lifecycle hooks; per-call character/token budgets; isolation pushed into the query. +**Reject:** the tool triple as the *whole* contract — OpenHuman's surface is an order of magnitude +larger (trees, diffs, goals, sources, sync, entities), which is exactly why capabilities must be +negotiated rather than assumed. **Also reject:** provider-authored lifecycle hooks. In OpenClaw the +plugin hooks the turn; here the kernel does, so policy cannot be bypassed by a driver. + +--- + +## 3. The contract: `tinycortex-api` + +### 3.1 Crate carve-out (the enabling move) + +Today the shared value types live in `tinycortex::memory`, so any driver depending on the contract +drags in SQLite, the retrieval engine, and the job model.

Both-ways tests per family, mirroring `channels_controllers_{registered,absent}`. + +### 3.4 The guard (non-negotiable) + +`MemoryGuard` wraps the bound driver and is the only handle product code ever +receives. It enforces, in order: + +1. `SecurityPolicy` tier + workspace/action-root path rules; +2. `source_scope` per-turn allowlist — **applied as a query predicate passed to the driver**, not + as a post-filter (OpenClaw's isolation lesson; also what today's W5 seam test pins); +3. `MemoryTaint` stamping on every write — the driver receives taint, never assigns it; +4. redaction (`memory/util/redact.rs`) on content leaving the process for an `external` driver; +5. egress budget + `trust_state` check for `external` drivers; +6. char/token budgets for auto-recall/auto-capture; +7. audit event on the bus + tracing span with `driver_id`, `capability`, `namespace`. + +Steps 4–5 are new and exist because "memory" is the most sensitive data in the product. An +`external` driver bind requires an explicit `trust_state = "trusted"` and, on first bind, a +one-time user consent recorded in config. Fail-closed: unset trust ⇒ refuse to bind, fall back to +embedded, surface in status. + +### 3.5 Lifecycle hooks (kernel-owned) + +- **auto-recall** — before an interactive turn, the kernel calls `recall` and injects results + under a `max_context_tokens` budget (default 2000, OpenClaw parity). +- **auto-capture** — after a turn, the kernel decides *whether* to capture (existing + `remember.rs` / `preferences.rs` policy) and calls `store`. +- **maintenance tick** — the existing scheduler drives `MemoryMaintenance::consolidate` if + advertised; the embedded driver maps it to seal/cascade/reembed. + +Drivers do not hook the agent loop. Same rule as `queue::run_once`: the host owns the loop, the +engine owns one step. + +--- + +## 4. Drivers + +### 4.1 `tinycortex` — embedded default + +`src/openhuman/memory_adapter/embedded/` implements every family over the existing seam +(`src/openhuman/tinycortex/`). Zero new engine logic: it is a re-shaping of the current direct +calls into contract methods. Advertises all 13 families. This is the compatibility anchor — the +parity harness compares it against pre-change behaviour. + +### 4.2 `http` — the external transport adapter + +`src/openhuman/memory_adapter/http/` implements every family by translating to a documented +JSON wire contract, so a third-party backend never depends on Rust or on this repo: + +``` +POST /v1/handshake → { contract_version, driver_id, capabilities[] } +POST /v1/memory/store { namespace, key, content, category, taint, session_id } +POST /v1/memory/recall { query, namespace, limit, filters, scope_allowlist[] } → ranked[] +POST /v1/memory/forget { namespace, key | query } +POST /v1/memory/ingest { source_ref, content, mime, taint } +GET /v1/memory/export → NDJSON stream +POST /v1/memory/import ← NDJSON stream +GET /v1/health → { status, detail } +``` + +Unsupported family ⇒ the endpoint is absent from `capabilities[]` and returns `501`; the adapter +maps that to `MemoryError::Unsupported`. Auth via a keychain-resolved bearer. The handshake pins +the contract version; a major mismatch refuses the bind. + +**`supermemory` reference driver** is a thin config profile over `http` (base URL, auth, field +mapping), shipped as a worked example plus a conformance-suite run — not special-cased in code. + +### 4.3 `mcp` — opportunistic + +For backends that already speak MCP, an adapter maps the families onto MCP tool calls through the +existing `mcp_client`. Lower priority; `http` covers the demand. + +### 4.4 `composite` / `mirror` + +Per kernel spec §3.5. `mirror` is the **migration path**: bind +`mirror { primary = "tinycortex", secondary = "supermemory" }`, backfill via +`export`→`import`, verify with the conformance suite, then re-bind to the secondary. + +### 4.5 Config + +```toml +[subsystems.memory] +driver = "tinycortex" + +[subsystems.memory.hooks] +auto_recall = true +auto_capture = true +max_context_tokens = 2000 +recall_max_chars = 1000 +capture_max_chars = 500 + +[subsystems.memory.drivers.supermemory] +class = "external"; transport = "http" +endpoint = "https://api.supermemory.ai" +credential_ref = "keychain:supermemory" +trust_state = "untrusted" # must be explicitly raised before bind succeeds +``` + +The existing `[memory]`, `[memory_tree]`, `[[memory_sources]]` blocks stay as-is and map into the +embedded driver's options; no user-visible config break. + +--- + +## 5. RPC & tools (unchanged surface) + +Method names, params, and payloads are **unchanged** — `memory*`, `memory_tree*`, `memory_sync*`, +`memory_sources*`, `memory_diff*`, `memory_goals*` all keep their contracts. Handlers stop calling +`memory::global::client()` and call `memory::subsystem::guard()` instead. Two additions: + +- `memory_provider_status` — bound driver id, class, health, contract version, capabilities, + last error. Drives the UI's capability-aware rendering. +- `memory_export` / `memory_import` — provider-agnostic NDJSON portability, gated by the approval + gate (a full memory export is a high-consequence action). + +--- + +## 6. Consolidation: what moves into TinyCortex + +### 6.1 Re-disposition vs. the 2026-07-28 cutover evaluation + +That evaluation asked *"is this product policy or engine logic?"* and concluded the remaining +`memory*` modules must stay. Under the kernel criterion (kernel spec §4) the question becomes +*"would a Supermemory-only build still need this file?"* — and several modules it retained are +**implementation of the default driver**, which is exactly where they belong once a second driver +is possible. Its core warning still holds and is honoured here: RPC, policy, secrets, and runtime +composition must **not** move into the crate. + +### 6.2 Moves to `vendor/tinycortex` + +| Host module | Why it moves | Lands as | +| --- | --- | --- | +| `memory_store/namespace_store/*` (the ten-table tier: `memory_docs`, `graph_*`, `episodic_log`+fts, `event_log`+fts+embeddings, `conversation_segments`, `segment_embeddings`, `vector_chunks`, `user_profile`) | TinyCortex-specific SQLite schema + migrations.

The +per-turn allowlist is a *host task-local* consumed *inside the engine*. Moving these files as-is +either drags `source_scope` into the crate (policy in the engine — the failure mode the +2026-07-28 cutover evaluation correctly warned about) or silently drops the allowlist. +**Fix:** invert it — retrieval takes an explicit `scope: Option<&ScopePredicate>` parameter, and +`MemoryGuard` populates it from the task-local at the call boundary. This is already the spec's +stated design (§3.4 step 2: *applied as a query predicate passed to the driver, not as a +post-filter*); it just has to land **before** the move, not after. Mechanical: five call sites, +one signature. +*(`memory_store/tools/raw_chunks.rs`, `memory_search/tools/{chunk_context,vector_search}.rs` also +read the task-local, but those are agent tools — kernel-side, staying put. No change needed.)* + +**(b) Config/event-bus reach-backs from `memory_tree`.** ~20 files under `memory_tree/{tree,score, +graph,health,retrieval}` import `crate::openhuman::config::` or `crate::core::event_bus`. +**Fix:** pass the derived options in (the `MemoryConfig` mapping the seam's `config.rs` already +does) and emit through the existing sink traits instead of the bus directly. Mechanical, but +broader than (a) — this is the bulk of `memory_tree`'s move cost. + +**Already fine, no work needed:** `memory_store/safety/*` is already a thin shim over the crate +scrubber; `namespace_store/query.rs` only *constructs* `MemoryTaint::Internal` (a type, which M0 +puts in `tinycortex-api`); `memory_sources/readers/*` only mention redaction in log comments. + +**Consequence for sequencing:** the M4-before-M8 rule is sharper than "all policy first". Only +class (a) is a policy-correctness gate. Class (b) is a decoupling chore that can run per-module in +parallel. So the move can start earlier and wider than the linear workstream table implies — +see the revised M8 split in §8. + +### 6.6 The shims must stay host-owned + +"Shims to expose the RPC APIs" has two possible shapes, and only one is correct: + +- ✅ **Host-owned thin controllers over the contract.** `memory/schemas/*.rs` keeps defining the + schema, keeps `handle_*` delegating — but delegates to `MemoryGuard` instead + of a concrete TinyCortex path.

Thin is what a good syscall table looks like. + +### 6.7 Expected shape after + +~74k LOC of host `memory*` reduces to a kernel-side surface dominated by RPC + tools + policy + +adapters. **Line count is not the goal and not the success metric** — the metric is that +`grep -rn "tinycortex::" src/openhuman/ --include=*.rs` returns hits only under +`memory_adapter/embedded/` and `src/openhuman/tinycortex/`. + +--- + +## 7.

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 3 repointing. harness/required_output.rs is pure logic with no host domains, so it moves onto tinyagents' RequiredOutput outright; session_io's enforce_required_output follows, converting at the read site in turn/core.rs. The 12 existing tests pass unchanged, which is the proof the swap preserves behaviour. Splits the mapper into per-section functions (turn_config_from, tool_config_from, memory_limits_from, apply_agent_config). The session builder takes a per-agent AgentConfig override, so mapping only from the global Config would have discarded it and run every agent on the global limits. Records what the rest of Phase 3 actually requires. The '37 files' figure counts host-adapter files that should keep reading Config; the moving set is ~19 files / 41 refs, and 11 of those are Config::load_or_init() — ambient loads that need config threaded through signatures, not repointed. The session cannot drop AgentConfig until Phase 2 rehomes session_dual_write / session_shadow_reads, and a parallel crate config was rejected because runtime.rs mutates max_tool_iterations after build.

Config::load_or_init() is NOT cached — it re-resolves the config dirs and re-reads config.toml on every call — and run_typed_mode called it six times, so a single sub-agent spawn hit the disk six times and could observe six different configs if the file changed mid-spawn. run_subagent now takes one snapshot and hands it down. The snapshot is Result, String> rather than Option because the integrations_agent path reports the load error to its caller while the other five degrade silently; keeping both shapes lets every site preserve its original failure behaviour exactly. It is taken after tier_gate_decision, since load_or_init can initialize config on first run and a spawn the tier gate rejects should not have that side effect. The sub-agent graph gets the same treatment: build_subagent_context_mw takes Option<&Config> (and is no longer async), plumbed through run_subagent_via_graph and a new AgentTurnRequest::config field so the custom-graph path keeps its [context] knobs instead of silently falling back to defaults. The four graph tests now pass None, which makes them hermetic — they previously read whatever config.toml happened to be on the developer's machine. Scope correction: task_dispatcher/ is NOT in the moving set. plan-agents §3 lists it beside dispatcher.rs mapping to harness::{tool_calling, hooks}, but that conflates two different modules. dispatcher.rs parses tool calls and is generic; task_dispatcher/ is a task-CARD board dispatcher reaching task_sources, threads, web_chat, todos, profiles and scheduler_gate. It stays host-side, so its three load_or_init calls are correct as they are.

The plan said 'transcript to crate JsonlChatHistory (transcript spec Option B)'. No such convergence is in progress. The real target, chosen and half-shipped under #4249, is the crate's Store/AppendStore journal at {workspace}/tinyagents_store/. Building a JsonlChatHistory would have added a THIRD store beside the legacy JSONL and the one being migrated to. session_import/ (2452 LOC) already had the importer, the live dual-write (default ON), and the shadow-read comparison. Only the reader flip (04.2) is outstanding. Legacy session_raw/*.jsonl stays authoritative for both read and write; the store is mirror-only. That sequencing was already correct. Closed the two legacy-shape gaps this phase's own exit criteria name, neither of which had a test: - date-grouped session_raw/DDMMYYYY/ must resolve the same store stream as a flat transcript. The key is the file stem, so the enclosing directory must not change it — if it ever did, every pre-migration session would read as Unavailable and the soak would look clean while covering nothing. - a legacy .md session must read Unavailable, never Divergence. Those predate the store so no stream exists; reporting divergence would flood the soak with false positives from every old transcript on disk, and the point of a soak is that a warning means something. session_shadow_reads now defaults ON to start the soak. Observation-only: legacy stays authoritative, the probe runs on a background task once per resume rather than per turn, a store-read failure degrades to Unavailable, and OPENHUMAN_SESSION_SHADOW_READS=0 kills it. Worst case is log noise, not a broken resume. Deliberately NOT flipping readers. That is bought with soak evidence, and no evidence exists until a release ships with the probe on.

This is where policy lives: taint, scope, redaction, approval and egress budget are enforced on the way in and out of the trait, because the crate deliberately knows nothing about them. agent/ does NOT call these yet, so the exit criterion is unmoved at 295 prod refs in session/. Writing the adapters and repointing the callers are separate pieces of work; only the first is done. Two defects fixed at integration, both compiling cleanly and failing silently: - security_gate: a channel RequireApproval verdict resolved to Allow. The mapping returned 'no verdict' assuming the call would fall through to the approval park, but the park is only reached from the shell and external-effect branches — so any ordinary tool was authorized with nobody asked. agent_tool_policy::engine files RequireApproval under blocked_tool_names alongside Deny, so this inverted the host's own semantics. Latent only because build_session does not currently emit RequireApproval, i.e. a trap armed for whoever turns it on. Now parks, and denies when no gate exists — the one place this set denies where the legacy middleware allows, argued in the module header. - experience_store: stable_experience_id_for_profile hashes task + tool sequence + outcome + profile and excludes agent_id. The native capture hook is protected only incidentally by always supplying a real tool sequence; this adapter has none, so two agents recording the same task with the same outcome collided on one id and put upserted, the second writer destroying the first's record. Agent id now folded into the hashed tool-sequence slot. Also corrected the plan's exit-criterion baseline: it read ~2000 refs, measured 295 in session/ production code. 21 TODO(phase4) markers remain, each naming an unreachable domain surface — honest gaps rather than stubs pretending to work.

Unscoped rows (`session_id: None`) stay visible, matching the +//! crate's own `InMemoryAgentMemory` scoping semantics. +//! - **Redaction is unconditional.** Every returned `text` and every citation +//! snippet goes through `sanitize_text`, so no raw store row reaches the +//! runtime.

It **fails closed to +//! [`MemoryTaint::ExternalSync`]**: an agent turn may have been summarizing an +//! email or a web page, this adapter cannot tell, and `ExternalSync` is the +//! value OpenHuman's subconscious gate treats as "unknown origin, refuse +//! external-effect tools".

Host [`BudgetGate`] backed by OpenHuman's scheduler gate, cost tracker, and +//! TokenJuice profile. +//! +//! This is `docs/specs/plan-agents.md` Phase 4. The agent runtime is being made +//! generic over its host, so it can no longer reach into +//! [`crate::openhuman::scheduler_gate`] or [`crate::openhuman::cost`] directly. +//! It declares [`BudgetGate`] instead, and this module is the single place +//! OpenHuman's three metering concerns meet it: +//! +//! * **admission / back-pressure** — [`scheduler_gate::wait_for_capacity`], +//! which owns the single-slot global LLM semaphore and the +//! AC-power / CPU / signed-out policy backoff; +//! * **budget refusal + accounting** — [`cost::CostTracker::check_budget`] and +//! [`cost::record_provider_usage`], priced through +//! [`cost::catalog::estimate_cost_usd`]; +//! * **compression advice** — the agent's +//! [`AgentTokenjuiceCompression`] profile, which decides how much lossy +//! compaction that agent tolerates. +//! +//! # Contract mismatches, and how each is resolved +//! +//! **1. `Usage` carries no model and no cost.** The crate's +//! [`Usage`] is pure token counts, but +//! [`cost::record_provider_usage`] is keyed by model and priced from a +//! `charged_amount_usd`. Two consequences: +//! +//! * *Model attribution* — the gate remembers the model from the most recent +//! [`BudgetGate::acquire`] and attributes [`BudgetGate::record`] to it, +//! falling back to the session's configured model. A gate instance is +//! per-session and the runtime calls `acquire` immediately before the call it +//! then `record`s, so in practice the pairing holds; with two calls genuinely +//! in flight on one gate the attribution can transpose. The alternative — +//! dropping the record entirely — loses the spend, which is strictly worse +//! for a budget guard. +//! * *Pricing* — with no provider-reported charge available, the cost is +//! estimated from the catalog. See the `TODO(phase4)` on [`Self::record`]: +//! OpenHuman will label that record `CostSource::ProviderCharged` even though +//! it is an estimate. +//! +//! **2. `compression_hint` must be cheap and synchronous**, but every budget +//! read in OpenHuman goes through a mutex and may touch the JSONL store. The +//! gate therefore caches a three-state budget pressure in an atomic, refreshed +//! on the async [`acquire`](Self::acquire) / [`record`](Self::record) paths — +//! exactly the "anything that needs I/O belongs in `record`, whose result this +//! can then consult" shape the trait documents. +//! +//! **3. The hint is a union with `SummarizationPolicy`, never an override.** +//! Returning [`CompressionHint::None`] here means *OpenHuman is not asking for +//! compression for a budget reason*; it is not a veto, and the crate's own +//! window-pressure policy still runs. That is why an agent whose TokenJuice +//! profile is `Off` yields `None` rather than anything stronger — `Off` opts +//! that agent out of *TokenJuice*, not out of summarization. +//! +//! Nothing here bypasses an OpenHuman guard: budget refusal still goes through +//! `check_budget` (which honours `cost.enabled`), and the scheduler-gate permit +//! is held for exactly the lifetime of the crate permit. + +use std::sync::atomic::{AtomicU8, Ordering}; +use std::sync::Arc; + +use async_trait::async_trait; +use parking_lot::RwLock; + +use tinyagents::error::{Result, TinyAgentsError}; +use tinyagents::harness::host::budget_gate::{ + BudgetGate, CallEstimate, CompressionHint, ContextState, Permit, +}; +use tinyagents::harness::usage::Usage; + +use crate::openhuman::config::{Config, DEFAULT_MODEL}; +use crate::openhuman::cost::{self, BudgetCheck}; +use crate::openhuman::inference::provider::types::UsageInfo; +use crate::openhuman::scheduler_gate; +use crate::openhuman::tokenjuice::AgentTokenjuiceCompression; + +/// Cached budget pressure, encoded for [`AtomicU8`]. +/// +/// A plain enum behind a lock would make [`BudgetGate::compression_hint`] — +/// which the runtime calls between every iteration of a turn — take a lock on +/// the hot path.

That +//! keeps one source of truth for section ordering, the grounding contract, and +//! the global style suffix. +//! +//! # Contract mismatches resolved here +//! +//! 1. **Per-turn call vs. frozen prefix.** The crate consults a composer on +//! *every* turn (`context_composer.rs`: "a host whose learned context … +//! changes mid-session needs the later turns to see it"). OpenHuman's +//! pipeline goes the other way: `SystemPromptBuilder::build`'s rustdoc +//! states the rendered bytes are "intended to be **frozen for the whole +//! session**" so the inference backend's prefix cache hits. Both are +//! honoured by construction — every input this adapter feeds the builder is +//! a snapshot captured at *construction* time (config, learned context, +//! connected integrations), so recomposing per turn yields byte-identical +//! output unless the host deliberately builds a new composer. The two +//! genuinely time-varying sections in the default chain +//! (`DateTimeSection`, and the on-disk files `IdentitySection` reads) are +//! OpenHuman's pre-existing behaviour on the main-agent path, not something +//! this seam introduces. +//! 2. **`thread_id` and `user_text` are unused inputs.** `PromptContext` has no +//! thread field and no turn-text field: OpenHuman scopes learned context +//! *outside* the prompt layer and pre-fetches it (see every existing +//! `PromptContext { learned: … }` call site). Rather than invent a +//! thread-keyed fetch, this adapter takes a caller-supplied +//! [`LearnedContextData`] snapshot — exactly the established pattern — and +//! logs the thread id for correlation. See the TODO on +//! [`OpenHumanContextComposer::learned`]. +//! 3. **`preamble` returns an empty `Vec`, always.** OpenHuman has no separate +//! preamble concept: goals, pinned context, and memory blocks are all +//! rendered *into* the system prompt as `PromptSection`s. Per the trait's +//! "Empty is not failure" note this is the normal, correct answer, not a +//! gap — synthesising extra messages here would duplicate content the +//! system prompt already carries. +//! +//! # Policy +//! +//! The `agents_md_enabled` config gate is honoured: when it is off, both +//! AGENTS.md layers are handed to the builder as `None` rather than being +//! loaded. `load_agents_md_layers` performs the `O_NOFOLLOW` path hardening +//! that keeps a symlinked project-layer `AGENTS.md` from leaking arbitrary +//! host files into the prompt (and thence to the inference provider); this +//! adapter goes through it rather than reading the files itself. + +use std::collections::HashSet; +use std::sync::Arc; + +use async_trait::async_trait; +use tinyagents::error::{Result as TinyAgentsResult, TinyAgentsError}; +use tinyagents::harness::host::{ContextComposer, TurnContextRequest}; +use tinyagents::harness::message::Message; + +use crate::openhuman::agent::prompts::{ + load_agents_md_layers, render_connected_identities, AgentsMdContent, ConnectedIntegration, + LearnedContextData, PromptContext, PromptTool, SystemPromptBuilder, ToolCallFormat, +}; +use crate::openhuman::config::{Config, DEFAULT_MODEL}; +use crate::openhuman::skills::Workflow; + +/// Composes OpenHuman's system prompt for a TinyAgents turn. +/// +/// Holds a snapshot of everything the prompt pipeline needs that is *not* +/// carried on [`TurnContextRequest`].

Host adapter: [`tinyagents::harness::host::ExperienceStore`] backed by +//! OpenHuman's `agent_experience` domain. +//! +//! This is `docs/specs/plan-agents.md` Phase 4. The crate's runtime records what +//! it learned about *doing* a task and reads prior attempts back before a +//! similar one. OpenHuman already has exactly that domain — the Hermes-style +//! procedural memory in [`crate::openhuman::agent_experience`], written today by +//! [`AgentExperienceCaptureHook`](crate::openhuman::agent_experience::AgentExperienceCaptureHook) +//! and read by the retrieval path — so this adapter is a translation layer over +//! [`AgentExperienceStore`], not a new store. +//! +//! # The namespace separation the trait insists on +//! +//! The trait's module doc is emphatic that this is **not** `AgentMemory`: +//! procedural (how the agent performed) versus declarative (what the user +//! knows). OpenHuman shares one backing store between them — both go through +//! `Arc` — but they do **not** share a namespace: everything here is +//! confined to +//! [`AGENT_EXPERIENCE_NAMESPACE`](crate::openhuman::agent_experience::AGENT_EXPERIENCE_NAMESPACE) +//! under `experience/` keys, which is precisely the "a host that has only +//! one backing store must still keep the two namespaces separate" case. Nothing +//! in this file reads or writes user memory namespaces. +//! +//! # Contract mismatches resolved here +//! +//! 1. **Ternary vs boolean outcome.** OpenHuman has +//! [`ExperienceOutcome::Partial`]; the crate's `Experience` has only +//! `success: bool`. Writing collapses `false` to `Failure`; reading maps +//! `Success` to `true` and both `Failure` and `Partial` to `false`. Partial +//! is *not* a success, and rounding it up would present a recovered-after- +//! failure run as a clean one. The nuance survives in the prose we carry +//! back in `outcome`, which names the OpenHuman outcome explicitly. +//! 2. **`lesson` is required; `Experience::outcome` may be empty.** The store +//! rejects a blank `lesson` +//! ([`AgentExperienceStore::put`]). The trait documents an empty `outcome` as +//! normal *and* says `record` returning `Err` means the record was lost. So a +//! blank outcome gets a synthesized, honest lesson line rather than an error. +//! 3. **`agent_id` is a score bonus, not a filter.** OpenHuman's +//! `score_experience` only *boosts* an agent match, so a retrieval seeded +//! with an agent id can still return another agent's records. The trait +//! promises "prior attempts by `agent`", so this adapter filters the hits by +//! agent id after retrieval. Filtering (rather than relaxing the promise) is +//! the safe direction: it can only remove rows. +//! 4. **Redaction stays with the host.** `put` runs the domain's +//! [`redact_text`](crate::openhuman::agent_experience::redact_text) over the +//! stored fields; this adapter also redacts on the way *in* before +//! truncating, so a secret cannot survive by being pushed past the truncation +//! boundary. Nothing here bypasses that guard. +//! 5. **No profile invention.** OpenHuman partitions experience by agent +//! profile. The crate has no notion of one, so the profile is supplied to the +//! adapter at construction and stamped onto every write; a profile-less +//! adapter reproduces the legacy, unpartitioned behaviour byte-for-byte. + +use std::sync::Arc; + +use async_trait::async_trait; +use tinyagents::error::{Result, TinyAgentsError}; +use tinyagents::harness::host::{Experience, ExperienceStore}; + +use crate::openhuman::agent_experience::store::{AgentExperienceStore, ExperienceQuery}; +use crate::openhuman::agent_experience::types::{ + redact_text, stable_experience_id, stable_experience_id_for_profile, AgentExperience, + ExperienceHit, ExperienceOutcome, ExperienceSource, +}; +use crate::openhuman::memory::Memory; + +/// Character cap applied to the prose fields written into the store. +/// +/// Mirrors the `MAX_SUMMARY_CHARS` used by +/// [`AgentExperienceCaptureHook`](crate::openhuman::agent_experience::AgentExperienceCaptureHook) +/// so records written through the crate runtime and records written by the +/// native hook are the same shape in the store and render identically in the +/// experience prompt block.

Host adapter for [`tinyagents::harness::host::LearningSink`] — the seam the +//! generic agent runtime uses to hand a finished turn to OpenHuman's +//! self-learning subsystem. +//! +//! This is `docs/specs/plan-agents.md` Phase 4. OpenHuman already has a +//! post-turn learning fan-out: [`crate::openhuman::agent::hooks::PostTurnHook`] +//! implementations (`UserProfileHook`, `ToolTrackerHook`, `ReflectionHook`, +//! `ToolMemoryCaptureHook`, `AgentExperienceCaptureHook`, `ArchivistHook`, …) +//! dispatched by [`crate::openhuman::agent::hooks::fire_hooks`]. That function +//! is already exactly the shape the crate's trait doc asks for — it +//! `tokio::spawn`s every hook and returns immediately, logging failures rather +//! than propagating them. So this adapter is deliberately thin: translate +//! [`TurnSummary`] into a [`TurnContext`] and enqueue. +//! +//! # Contract mismatches, and how each is resolved +//! +//! **1. `tools_invoked` is names-only; `TurnContext.tool_calls` is outcomes.** +//! This is the load-bearing mismatch. [`TurnSummary::tools_invoked`] carries a +//! deduplicated list of tool *names* by design — the crate doc is explicit that +//! arguments and results must never travel this path because the record is +//! built to be persisted. OpenHuman's +//! [`crate::openhuman::agent::hooks::ToolCallRecord`] is the opposite: it exists +//! to carry `success`, `duration_ms`, and a sanitized `output_summary`, and +//! every outcome-mining hook (`ToolTrackerHook`, `AgentExperienceCaptureHook`) +//! reads precisely those fields. +//! +//! There is no honest projection from one to the other. Synthesizing records +//! with `success: true, duration_ms: 0` would make `ToolTrackerHook` write +//! fabricated success rates and a corrupted running average into the +//! `tool_effectiveness` namespace, and would make +//! `AgentExperienceCaptureHook` mine "successful multi-tool experience" +//! candidates from a turn whose tools may all have failed. Persisting an +//! invented outcome is worse than persisting none, so **`tool_calls` is left +//! empty** and the names are emitted to the log only. The outcome-driven hooks +//! then self-disable (both early-return on an empty `tool_calls`), which is the +//! correct degradation: silent no-op, not silent lies. +//! +//! The hooks that read the *text* of the turn — `UserProfileHook`'s preference +//! extraction and `ReflectionHook`'s heuristic cue fast-path, which runs before +//! and independently of the `min_turn_complexity` gate — are unaffected and +//! keep working from a names-only summary. +//! +//! **2. `thread_id` vs `session_id`.** `TurnContext.session_id` is populated +//! host-side from the harness' `event_session_id`; a [`TurnSummary`] only +//! carries a [`tinyagents::harness::ids::ThreadId`]. The thread id is the +//! closest available correlation key, so it is mapped through. The visible +//! consequence is that `ReflectionHook`'s `max_reflections_per_session` throttle +//! becomes per-thread rather than per-session on this path — a slightly +//! different, but not incorrect, bucketing. +//! +//! **3. Missing fields.** [`TurnSummary`] has no wall-clock duration and no +//! model-call count, so `turn_duration_ms` is `0` and `iteration_count` is `1`. +//! Neither is read by any gate; they are reporting fields only. `entrypoint` is +//! `None` because the crate summary has no notion of a channel. +//! +//! **4. Errors are advisory.** The trait doc is emphatic that the turn is +//! already committed and an `Err` must not roll it back. `fire_hooks` is +//! infallible and non-blocking, so [`OpenHumanLearningSink::on_turn_complete`] +//! always returns `Ok(())`; hook failures surface in the host log where they +//! belong. +//! +//! # Domains deliberately not wired here +//! +//! - [`crate::openhuman::learning::transcript_ingest`] is *transcript-file* +//! driven (`ingest_transcript_path` / `ingest_session_transcript` take a +//! session `.jsonl` on disk) and runs on session close, not per turn. A sink +//! invocation has no transcript to point at. +//! - [`crate::openhuman::subconscious`] is scheduler-driven: its public entry +//! point is `SubconsciousInstance::tick`, polled by the heartbeat engine. +//! There is no per-turn ingestion API to call. +//! +//!

Host capability: **which** model answers a turn. +//! +//!

The mapping performed here is exactly the one the rest of the core already +//! performs: *workload role* → provider string → concrete `ChatModel`.

Building a client by any other route would bypass that guard. +//! +//! # Contract mismatches resolved here +//! +//! 1. **`State` erasure.** The trait is generic over the harness state +//! (`ModelResolver` must return `Arc>`), but +//! every model OpenHuman builds is a `ChatModel<()>` — the core's harness +//! carries its per-turn context in task-locals and `RunContext`, not in a +//! typed state value. [`StatelessModel`] bridges the two: it implements +//! `ChatModel` for *any* `State` by discarding the state reference and +//! invoking the inner model with `&()`. That is lossless today precisely +//! because no OpenHuman model reads state; if one ever does, it must stop +//! going through this wrapper rather than silently observing `()`. +//! +//! 2. **"resolve is cheap, and must not be memoized by the caller."** The trait +//! tells the *runtime* not to cache, which leaves the host free to. A fresh +//! `create_chat_model_with_model_id` per turn would hand back a new provider +//! client and throw away its connection pool — the exact waste the trait's +//! `Arc` return is trying to avoid. Since this resolver holds an immutable +//! `Arc` snapshot, the answer for a given workload role cannot change +//! over its lifetime, so [`OpenHumanModelResolver`] memoizes per role. A +//! caller that needs re-resolution after a config edit constructs a new +//! resolver, which is how every other `Arc` holder in the core works. +//! +//! 3. **Tiered routing is not represented.** OpenHuman's richer per-turn model +//! bundle (primary + workload-tier fallback routes + summarizer) is +//! `TurnModelSource` / `TurnModels` in `super::super` — a *bundle*, not one +//! `Arc`, so it does not fit this signature.

The crate deliberately keeps `ProgressEvent` at five variants and +//! says so in its own module docs: a presentation-shaped field added there +//! becomes a compatibility surface for every consumer of a redistributed +//! crate. So the projection runs here, host-side, and `AgentProgress` never +//! crosses into `vendor/tinyagents`. +//! +//! # Why it forwards to an mpsc channel and not to `publish_web_channel_event` +//! +//! The obvious-looking shortcut — build a `WebChannelEvent` and publish it +//! straight onto the web-channel bus — is wrong here. Everything that makes a +//! web-channel progress event correct is owned by +//! [`crate::openhuman::web_chat::progress_bridge::spawn_progress_bridge`]: the +//! per-request monotonic `seq` stamp the frontend dedups on, the +//! `TurnStateMirror` snapshot, the run-ledger upserts, the tracing span +//! collector, and the client/thread/request routing ids that a `ProgressEvent` +//! does not carry at all. A second independent producer of "what is happening +//! now" would drift from the bridge's ordering and from the persisted turn +//! state, and the drift would only show up as a mis-rendered timeline. +//! +//! So this sink writes `AgentProgress` into the same +//! `mpsc::Sender` the existing agent turn loop uses +//! (`Agent::set_on_progress`), and the established bridge does the publishing. +//! `publish_web_channel_event` is still the terminal step — one hop further +//! down, where it already lives. +//! +//! # Contract mismatches, and how they are resolved +//! +//! * **`emit` cannot fail.** It uses `try_send` and *drops* the event when the +//! bridge is behind or gone, per the crate's "dropping progress events is +//! always preferable to slowing the turn" rule. It never awaits the channel's +//! capacity, never blocks, and never panics. +//! * **The coarse stream has no iteration boundary.** `AgentProgress` carries a +//! 1-based `iteration` on almost every variant; `ProgressEvent` has no +//! equivalent. The sink keeps a local round counter that advances on each +//! `ToolCall` — a *lower bound* on the real iteration count, since a turn +//! with no tool calls is one round. It is used for `iteration` fields and for +//! `TurnCompleted { iterations }`. See the `TODO(phase4)` below. +//! * **`ProgressEvent::Error` has no `AgentProgress` counterpart.** The host +//! enum models a turn's failure through the turn's own `Err` return (which +//! `web_chat::ops` renders as `chat_error`), not through a progress event. +//! Synthesising a `TurnCompleted` here would report a failed turn as a +//! successful one to the ledger and the timeline, so the sink logs the +//! failure and forwards nothing. +//! * **`ProgressEvent::Finished { usage }` is not a cost event.** +//! `AgentProgress::TurnCostUpdated` requires a model id and a USD total that +//! the crate event does not carry, and OpenHuman's authoritative cost figures +//! come from the inference layer's charged amounts.

[`SecurityPolicy::classify_command`] / [`SecurityPolicy::check_gated_command`] +//! / [`SecurityPolicy::gate_decision`] triad, and [`AutonomyLevel`]. +//! - [`crate::openhuman::approval`] — the process-global [`ApprovalGate`], +//! [`GateOutcome`], and the `summarize_action` / `redact_args` pair that keep +//! raw arguments out of the approval card. +//! - [`crate::openhuman::agent_tool_policy`] — a pre-built [`ToolPolicySession`] +//! (channel permission boundary). +//! - [`crate::openhuman::prompt_injection`] — [`enforce_prompt_input`] for +//! [`SecurityGate::screen_input`]. +//! +//! # Contract mismatches, resolved in favour of the existing guard +//! +//! 1. **"Answer, do not act" vs. the rate limiter.** OpenHuman's +//! [`SecurityPolicy::enforce_tool_operation`] *records* an action against the +//! sliding-window tracker as a side effect of authorizing one. The trait +//! forbids acting, and the tools call it themselves anyway, so this adapter +//! reads the non-mutating [`SecurityPolicy::is_rate_limited`] instead. A gate +//! that called `enforce_tool_operation` would double-count every tool call +//! and exhaust the hourly budget at twice the configured rate. +//! 2. **The audit trail is only half-writable from here.** `intercept_audited` +//! hands back a `request_id` so the caller can log the *terminal* status once +//! the tool resolves — but this trait returns before the tool runs and is +//! never called again. So the adapter uses the plain +//! [`ApprovalGate::intercept`] and leaves terminal-status recording to +//! `ApprovalSecurityMiddleware`, which still wraps execution. +//! 3. **No `Redacted` outcome is ever produced.** OpenHuman can *detect* PII +//! ([`crate::openhuman::security::pii::scan`]) but exposes no verified +//! public helper that rewrites free text into a redacted copy — the one that +//! exists (`approval::redact::scrub_paths`) is private and shaped for JSON +//! argument maps. Screening therefore only ever passes or blocks. See the +//! `TODO(phase4)` in [`OpenHumanSecurityGate::screen_input`]. +//! 4. **An absent approval gate allows, it does not deny.** When +//! [`ApprovalGate::try_global`] is `None` (CLI, headless embed, tests) a +//! `Prompt` decision cannot be resolved by a human. This adapter warns +//! loudly and allows — byte-for-byte the behaviour of the +//! `ApprovalSecurityMiddleware` it stands in for. Changing it to a denial +//! here would be a *new* restriction invented by an adapter, not the +//! honouring of an existing guard, and would break every non-desktop host. +//! The deterministic `Block` path is unaffected: it never consults the gate. +//! +//! **One exception, and it runs the other way.** A `RequireApproval` verdict +//! from the *channel tool policy* denies when no gate is installed. That is +//! not an invented restriction: `agent_tool_policy::engine` already files +//! `RequireApproval` under `blocked_tool_names` alongside `Deny`, so the +//! thing being honoured is a block, and the only thing that can lift it is a +//! human actually approving. Allowing instead would turn the channel's +//! strictest non-deny setting into its weakest on precisely the hosts with +//! no human present. See [`ToolPolicyVerdict`]. +//! +//!

Host implementation of [`ToolOutcomeClassifier`] over OpenHuman's +//! `tool_status` domain. +//! +//! This is `docs/specs/plan-agents.md` Phase 4. The agent runtime knows a tool +//! call returned; it does not know whether the thing that came back is a +//! success, something to re-dispatch, or a dead end. OpenHuman already owns that +//! judgement in [`crate::openhuman::tool_status`], whose +//! [`classify`](crate::openhuman::tool_status::classify) turns raw tool error +//! text into a [`ClassifiedFailure`](crate::openhuman::tool_status::ClassifiedFailure) +//! (a [`ToolFailureClass`] plus a user-facing category). This adapter is the one +//! place that mapping is projected onto the crate's three-way +//! [`OutcomeClass`]. +//! +//! # Contract mismatches resolved here +//! +//! **1. `ClassifiedFailure::recoverable` is NOT the retryability signal.** +//! The tempting one-liner is `if failure.recoverable { RetryableFailure }`. It +//! is wrong. `recoverable` means `category == FailureCategory::Recoverable`, and +//! [`ToolFailureClass::Unknown`] — *anything the heuristic could not classify* — +//! sits in that category so the UI can offer "try again" copy. The crate's +//! contract for [`OutcomeClass::RetryableFailure`] is much stronger: it is "an +//! assertion by the host that repeating is acceptable", made without knowing +//! whether the tool had side effects. An unclassified failure is precisely the +//! case where OpenHuman does *not* know that. So this adapter branches on the +//! **class**, not on `recoverable`, and only the three transient classes are +//! called retryable. +//! +//! That is not a new policy invention — it is the split OpenHuman's own steering +//! middleware already makes. `TinyAgents`' recoverable-failure headroom ladder +//! (`middleware.rs`, issue #4463 part 4) gates on exactly +//! `Timeout | ServiceUnavailable | ModelConnection` and lets everything else, +//! `Unknown` included, fall through to the hard-failure path. Mapping `Unknown` +//! to [`OutcomeClass::PermanentFailure`] keeps this seam consistent with that +//! guard and matches the crate's own documented safe default +//! (`ErrorFieldClassifier` classifies every error as permanent for the same +//! side-effect reason). +//! +//! **2. `classify` wants a `timed_out` flag the runtime does not carry.** +//! [`ToolResult`] has no "the executor stopped this at its deadline" bit, so the +//! flag is derived the same way `TinyAgentsToolStatusMiddleware` derives it — +//! sniffing `"timed out"` out of the combined failure text. Doing it identically +//! is the point: the middleware and this classifier must not disagree about +//! whether a call timed out. +//! +//! **3. Error text lives in two places.** The middleware combines +//! [`ToolResult::error`] and [`ToolResult::content`] before classifying (#4459), +//! because the policy markers and timeout phrases are emitted by the tool layer +//! into whichever of the two it had to hand. This adapter uses the same +//! combination, so a `[policy-denied]` marker is honoured wherever it landed and +//! a user refusal can never be re-dispatched. +//! +//!

Investigated the repointing and found it blocked rather than merely hard; landed the one piece that is not. Four findings, each measured, recorded in docs/specs/plan-agents.md: 1. The exit criterion counts the wrong code. Of 118 non-adapter refs in session/, 46 are in builder/ (assembly, which becomes the trait impls), 16 are field type annotations, 13 are state management. Only turn/'s ~40 is genuine runtime consumption, so "drive session/ down to the adapter layer" cannot happen by repointing — most of those refs ARE that layer. 2. The session distributes handles more than it consumes them. All 11 uses of self.memory hand the Arc to a collaborator that needs the full domain interface, so swapping the field to Arc breaks them. 3. No capability trait fits an existing call shape 1:1. ContextComposer returns String where the turn needs structured LearnedContextData for its own SystemPromptBuilder; ToolOutcomeClassifier's only consumer is progress_tracing/, which the plan deletes rather than moves. 4. Four adapters (BudgetGate, ContextComposer, ModelResolver, and the policy half of SecurityGate) need Arc, which the session did not hold — it holds AgentConfig plus an optional, misleadingly-named integration_runtime_config. That is the Phase 3 blocker, which is blocked on Phase 2's reader flip, which is blocked on the parity soak needing a shipped release. The program is now gated on elapsed time, not effort. Unblocked and done here: integration_runtime_config becomes runtime_config: Option> — a first-class shared handle rather than an integrations-specific one — so those four adapters become constructible without waiting on Phase 2. Adds runtime_config() and host_capabilities_available(), plus host_agent_memory() and host_experience_store() for the two adapters that need only Arc and therefore work on the bare-builder path too. host_capabilities_available() keeps "this session cannot answer that" distinct from "the capability failed" — the same absence-versus-failure rule the traits are built on. Adapters are built on demand rather than stored: a stored handle could drift from self.memory if the backend were swapped. Full suite 12770 pass / 0 fail.

That holds only while the process-global signal store is uninitialized; once any other test in the binary initializes it the call succeeds and unwrap_err() panics. The property under test is about param validation, which an Ok satisfies as well as a non-param error, so the assertion now only runs when there is an error. Two siblings carried the same latent bug and are fixed too — signal_register_encryption_key_does_not_leak_key_material calls the very same handler, and directory_find_by_encryption_key_with_valid_param_fails_at_client has the identical shape against the directory handler. archivist — NOT FIXED. Two real isolation defects corrected, but the flake remains, so this is hardening rather than a fix. Both defects are genuine: these tests document themselves as hermetic and are not. 1. test_config_with_tree() claimed to "disable embedding so ingest doesn't fail trying to contact Ollama" but set memory_tree.embedding_*, while the tree ingest reads memory.embedding_model via memory::tinycortex::config::memory_config_from — which defaults to the CLOUD model "embedding-v1". So ingest really was calling the managed embedding service. Now sets embeddings_provider = "none", which memory::tree_e2e_tests::pipeline_works_with_embeddings_disabled pins as the route to InertEmbedder. 2. ingest_chat builds its OWN chat provider from Config (tinycortex::ingest::context -> scoring_config -> build_chat_provider), so it ignored the StubChatProvider wired into the hook. The five tree-ingest tests now run inside chat::test_override::with_provider, a task-local hook that build_chat_runtime already checks and that nothing was using. What was ruled out for the archivist flake, so the next attempt does not repeat it: instrumenting tree_ingest.rs with panics showed that on failing runs the ingest never returns Err, never sees empty messages, and never reports chunks_written == 0. The tests fail with "got 0 chunks" while none of those probes fire, which points at pipe_segment_to_tree not being reached at all — i.e. the segment boundary not firing — rather than at the ingest itself. Separately, the suite has a broader population of load-sensitive tests (memory::chat, memory::ops::documents, subconscious::monitors) that fail intermittently. An A/B with these changes stashed failed too, so that population is pre-existing and not caused here.

Existing `tinycortex::memory::{…}` paths keep resolving via -re-export, so the ~30 host consumers and `memory::traits` are untouched. - -Value types moving to the API crate verbatim: `MemoryEntry`, `MemoryCategory`, `MemoryTaint`, -`RecallOpts`, `NamespaceSummary`, plus chunk/source/tree DTOs (`ChunkRef`, `SourceRef`, -`TreeNodeRef`, `IngestRequest`, `IngestOutcome`, `DiffEntry`, `GoalRecord`, `ToolMemoryRecord`). - -> `MemoryTaint` is security-critical and fails closed to `ExternalSync`. It moves **byte-identical** -> and keeps its dedicated seam test. Provenance semantics are contract, not implementation. - -### 3.2 Capability families - -A driver implements `MemoryProvider` plus any subset of the families it advertises: - -| Family | Trait | Methods (indicative) | Required? | -| --- | --- | --- | --- | -| `core` | `MemoryCore` | `store`, `store_with_taint`, `get`, `forget`, `list`, `namespaces` | **yes** | -| `recall` | `MemoryRecall` | `recall(query, RecallOpts) -> Ranked` | **yes** | -| `ingest` | `MemoryIngest` | `ingest_document`, `ingest_chat` (driver owns chunking + embedding) | no | -| `documents` | `MemoryDocuments` | namespace-document tier: `put_doc`, `get_doc`, `query_docs` | no | -| `tree` | `MemoryTree` | `query_source`, `drill_down`, `seal`, `cascade` | no | -| `entities` | `MemoryEntities` | entity index + edges + hotness | no | -| `graph` | `MemoryGraph` | kv-graph read/write | no | -| `diff` | `MemoryDiff` | snapshot capture + change computation | no | -| `goals` | `MemoryGoals` | goal extraction/records | no | -| `tool_memory` | `MemoryToolMemory` | per-tool learned memory | no | -| `sources` | `MemorySourceSink` | accept synced source items (host owns creds + schedule) | no | -| `maintenance` | `MemoryMaintenance` | reembed, compact, consolidate ("dream"), doctor | no | -| `portability` | `MemoryPortability` | `export(stream)`, `import(stream)` | **yes** | - -`core`, `recall`, and `portability` are mandatory: without them a driver is not a memory backend, -and without `portability` a user cannot leave it. Everything else degrades per kernel spec §3.3 — -the method is unregistered, the tool is absent, the UI hides the surface. - -### 3.3 Degradation map (what a minimal driver loses) - -| Absent capability | RPC unregistered | Agent tools absent | -| --- | --- | --- | -| `tree` | `memory_tree*`, retrieval drill-down | tree query/drill-down tools | -| `diff` | `memory_diff*` | diff tools | -| `goals` | `memory_goals*` | goal tools | -| `documents` | doc put/get/query | doc tools | -| `sources` | `memory_sources_sync`, `memory_sync*` | sync tools | - -The registration sites are already grouped per family in `src/core/all.rs` (each -`all_memory_*_registered_controllers()` call), so this is a filter at those call sites — not a -rewrite. Both-ways tests per family, mirroring `channels_controllers_{registered,absent}`. - -### 3.4 The guard (non-negotiable) - -`MemoryGuard` wraps the bound driver and is the only handle product code ever -receives. It enforces, in order: - -1. `SecurityPolicy` tier + workspace/action-root path rules; -2. `source_scope` per-turn allowlist — **applied as a query predicate passed to the driver**, not - as a post-filter (OpenClaw's isolation lesson; also what today's W5 seam test pins); -3. `MemoryTaint` stamping on every write — the driver receives taint, never assigns it; -4. redaction (`memory/util/redact.rs`) on content leaving the process for an `external` driver; -5. egress budget + `trust_state` check for `external` drivers; -6. char/token budgets for auto-recall/auto-capture; -7. audit event on the bus + tracing span with `driver_id`, `capability`, `namespace`. - -Steps 4–5 are new and exist because "memory" is the most sensitive data in the product. An -`external` driver bind requires an explicit `trust_state = "trusted"` and, on first bind, a -one-time user consent recorded in config. Fail-closed: unset trust ⇒ refuse to bind, fall back to -embedded, surface in status. - -### 3.5 Lifecycle hooks (kernel-owned) - -- **auto-recall** — before an interactive turn, the kernel calls `recall` and injects results - under a `max_context_tokens` budget (default 2000, OpenClaw parity). -- **auto-capture** — after a turn, the kernel decides *whether* to capture (existing - `remember.rs` / `preferences.rs` policy) and calls `store`. -- **maintenance tick** — the existing scheduler drives `MemoryMaintenance::consolidate` if - advertised; the embedded driver maps it to seal/cascade/reembed. - -Drivers do not hook the agent loop. Same rule as `queue::run_once`: the host owns the loop, the -engine owns one step. - ---- - -## 4. Drivers - -### 4.1 `tinycortex` — embedded default - -`src/openhuman/memory_adapter/embedded/` implements every family over the existing seam -(`src/openhuman/tinycortex/`). Zero new engine logic: it is a re-shaping of the current direct -calls into contract methods. Advertises all 13 families. This is the compatibility anchor — the -parity harness compares it against pre-change behaviour. - -### 4.2 `http` — the external transport adapter - -`src/openhuman/memory_adapter/http/` implements every family by translating to a documented -JSON wire contract, so a third-party backend never depends on Rust or on this repo: - -``` -POST /v1/handshake → { contract_version, driver_id, capabilities[] } -POST /v1/memory/store { namespace, key, content, category, taint, session_id } -POST /v1/memory/recall { query, namespace, limit, filters, scope_allowlist[] } → ranked[] -POST /v1/memory/forget { namespace, key | query } -POST /v1/memory/ingest { source_ref, content, mime, taint } -GET /v1/memory/export → NDJSON stream -POST /v1/memory/import ← NDJSON stream -GET /v1/health → { status, detail } -``` - -Unsupported family ⇒ the endpoint is absent from `capabilities[]` and returns `501`; the adapter -maps that to `MemoryError::Unsupported`. Auth via a keychain-resolved bearer. The handshake pins -the contract version; a major mismatch refuses the bind. - -**`supermemory` reference driver** is a thin config profile over `http` (base URL, auth, field -mapping), shipped as a worked example plus a conformance-suite run — not special-cased in code. - -### 4.3 `mcp` — opportunistic - -For backends that already speak MCP, an adapter maps the families onto MCP tool calls through the -existing `mcp_client`. Lower priority; `http` covers the demand. - -### 4.4 `composite` / `mirror` - -Per kernel spec §3.5. `mirror` is the **migration path**: bind -`mirror { primary = "tinycortex", secondary = "supermemory" }`, backfill via -`export`→`import`, verify with the conformance suite, then re-bind to the secondary. - -### 4.5 Config - -```toml -[subsystems.memory] -driver = "tinycortex" - -[subsystems.memory.hooks] -auto_recall = true -auto_capture = true -max_context_tokens = 2000 -recall_max_chars = 1000 -capture_max_chars = 500 - -[subsystems.memory.drivers.supermemory] -class = "external"; transport = "http" -endpoint = "https://api.supermemory.ai" -credential_ref = "keychain:supermemory" -trust_state = "untrusted" # must be explicitly raised before bind succeeds -``` - -The existing `[memory]`, `[memory_tree]`, `[[memory_sources]]` blocks stay as-is and map into the -embedded driver's options; no user-visible config break. - ---- - -## 5. RPC & tools (unchanged surface) - -Method names, params, and payloads are **unchanged** — `memory*`, `memory_tree*`, `memory_sync*`, -`memory_sources*`, `memory_diff*`, `memory_goals*` all keep their contracts. Handlers stop calling -`memory::global::client()` and call `memory::subsystem::guard()` instead. Two additions: - -- `memory_provider_status` — bound driver id, class, health, contract version, capabilities, - last error. Drives the UI's capability-aware rendering. -- `memory_export` / `memory_import` — provider-agnostic NDJSON portability, gated by the approval - gate (a full memory export is a high-consequence action). - ---- - -## 6. Consolidation: what moves into TinyCortex - -### 6.1 Re-disposition vs. the 2026-07-28 cutover evaluation - -That evaluation asked *"is this product policy or engine logic?"* and concluded the remaining -`memory*` modules must stay. Under the kernel criterion (kernel spec §4) the question becomes -*"would a Supermemory-only build still need this file?"* — and several modules it retained are -**implementation of the default driver**, which is exactly where they belong once a second driver -is possible. Its core warning still holds and is honoured here: RPC, policy, secrets, and runtime -composition must **not** move into the crate. - -### 6.2 Moves to `vendor/tinycortex` - -| Host module | Why it moves | Lands as | -| --- | --- | --- | -| `memory_store/namespace_store/*` (the ten-table tier: `memory_docs`, `graph_*`, `episodic_log`+fts, `event_log`+fts+embeddings, `conversation_segments`, `segment_embeddings`, `vector_chunks`, `user_profile`) | TinyCortex-specific SQLite schema + migrations. Supermemory has no `episodic_fts`. | `store::namespace` behind the `documents`/`graph` capabilities | -| `memory_store/content/{wiki_git,obsidian,obsidian_registry}` | On-disk content formats of the embedded engine | `store::content::{wiki_git,obsidian}`, feature-gated | -| `memory_store/{client,factories,kinds,traits}.rs` compatibility shims | Re-exports over crate types; the contract replaces them | deleted | -| `memory_tree/health/`, `memory_tree/io.rs`, `summarise.rs` residue | Health/doctor of *this* engine | `tree::health`, surfaced via `MemoryMaintenance::doctor` | -| `memory_search/*` remaining shims | Re-export layer over crate retrieval | deleted | -| `memory_queue/{store,worker,scheduler,types}.rs` residue | Engine job model; host keeps only the tokio loop that calls `queue::run_once` | crate `queue` | -| `memory_sources/{readers,registry,reconcile,status}.rs` | Reader/parser implementations | crate `sources` | -| `memory_sync/{canonicalize,sources,workspace,composio}` engine parts not yet flipped | Sync engine; host keeps schedulers, creds, bus, RPC | crate `sync` (feature-gated network) | -| `memory_diff`, `memory_goals`, `memory_conversations`, `memory_tools` store/type re-export files | Thin facades over crate modules | deleted; import `tinycortex::memory::*` directly | -| `memory/{ingest_pipeline,tree_source,query,util/*}` engine internals | Chunking/ranking/tree policy mechanics of the embedded engine | crate `ingest`/`tree`/`retrieval` | - -### 6.3 Stays in the host (kernel side) - -`memory/{ops,schemas,schema,read_rpc,rpc_models}` · `memory/tools/*`, `memory_search/tools/`, -`memory_tools` tool surface · `SecurityPolicy` gating, `source_scope`, `util/redact.rs` · -`preferences.rs`, `remember.rs`, `tree_policy.rs` (product policy over the tree, not the tree) · -`global.rs` → becomes the registry/bind site · `chat.rs` · credentials/keychain, Composio OAuth · -schedulers (`memory_sync/periodic.rs`), bus subscribers · config mapping · **new** -`memory_adapter/` (embedded, http, mcp, composite, guard). - -### 6.4 How much actually moves (measured, 2026-07-28) - -Measured over `src/openhuman/memory*`, classifying RPC/schema/ops/tools/bus/policy files as -kernel-side and everything else as engine: - -| Module | Total | Kernel-side | Engine (movable) | Tests | -| --- | ---: | ---: | ---: | ---: | -| `memory_store` | 17,433 | 572 | **16,861** | 5,033 | -| `memory_sync` | 17,204 | 2,246 | **14,958** | 1,813 | -| `memory` | 18,332 | 12,474 | 5,858 | 2,709 | -| `memory_tree` | 9,898 | 3,549 | 6,349 | 292 | -| `memory_sources` | 4,968 | 1,733 | 3,235 | — | -| `memory_queue` | 1,411 | 39 | **1,372** | 37 | -| `memory_diff` | 1,956 | 1,695 | 261 | — | -| `memory_tools` | 1,338 | 461 | 877 | 228 | -| `memory_goals` | 869 | 642 | 227 | — | -| `memory_conversations` | 858 | 833 | 25 | — | -| `memory_search` | 718 | 703 | 15 | — | -| **Total** | **74,985** | **24,947 (33%)** | **50,038 (67%)** | 10,112 | - -So roughly **two thirds of the host memory tree is movable engine code**, concentrated in -`memory_store`, `memory_sync`, `memory_tree`, and `memory_queue` — those four are 90% of the -movable mass and are near-totally engine (`memory_queue` is 97% engine, `memory_store` 97%). -Conversely `memory_conversations`, `memory_search`, `memory_diff`, and `memory_goals` are already -almost pure kernel-side surface: their remaining engine content is 25–261 LOC of facade, so those -directories effectively **collapse into shims** rather than "move". - -This is the answer to "can most of it move now": **yes by mass, and mostly in four directories** — -subject to §6.5. - -### 6.5 The one real blocker: engine→host reach-backs - -Twelve movable files reach *back* into host state, so they cannot be lifted as-is. Inventory: - -**(a) Task-local `source_scope` read from inside retrieval — the security-relevant one.** -`memory_tree/retrieval/{source,fast,drill_down,fetch,cover}.rs` call -`memory::source_scope::current_source_scope()` / `chunk_source_allowed_in()` directly. The -per-turn allowlist is a *host task-local* consumed *inside the engine*. Moving these files as-is -either drags `source_scope` into the crate (policy in the engine — the failure mode the -2026-07-28 cutover evaluation correctly warned about) or silently drops the allowlist. -**Fix:** invert it — retrieval takes an explicit `scope: Option<&ScopePredicate>` parameter, and -`MemoryGuard` populates it from the task-local at the call boundary. This is already the spec's -stated design (§3.4 step 2: *applied as a query predicate passed to the driver, not as a -post-filter*); it just has to land **before** the move, not after. Mechanical: five call sites, -one signature. -*(`memory_store/tools/raw_chunks.rs`, `memory_search/tools/{chunk_context,vector_search}.rs` also -read the task-local, but those are agent tools — kernel-side, staying put. No change needed.)* - -**(b) Config/event-bus reach-backs from `memory_tree`.** ~20 files under `memory_tree/{tree,score, -graph,health,retrieval}` import `crate::openhuman::config::` or `crate::core::event_bus`. -**Fix:** pass the derived options in (the `MemoryConfig` mapping the seam's `config.rs` already -does) and emit through the existing sink traits instead of the bus directly. Mechanical, but -broader than (a) — this is the bulk of `memory_tree`'s move cost. - -**Already fine, no work needed:** `memory_store/safety/*` is already a thin shim over the crate -scrubber; `namespace_store/query.rs` only *constructs* `MemoryTaint::Internal` (a type, which M0 -puts in `tinycortex-api`); `memory_sources/readers/*` only mention redaction in log comments. - -**Consequence for sequencing:** the M4-before-M8 rule is sharper than "all policy first". Only -class (a) is a policy-correctness gate. Class (b) is a decoupling chore that can run per-module in -parallel. So the move can start earlier and wider than the linear workstream table implies — -see the revised M8 split in §8. - -### 6.6 The shims must stay host-owned - -"Shims to expose the RPC APIs" has two possible shapes, and only one is correct: - -- ✅ **Host-owned thin controllers over the contract.** `memory/schemas/*.rs` keeps defining the - schema, keeps `handle_*` delegating — but delegates to `MemoryGuard` instead - of a concrete TinyCortex path. The crate never learns that JSON-RPC exists. -- ❌ **Crate-owned RPC exposed through a host shim.** If `tinycortex` gains schemas/handlers and - the host merely re-exports them, the dependency boundary inverts: the reusable engine now knows - OpenHuman's method names, error envelope, and policy vocabulary — and a second driver can no - longer satisfy the same RPC surface, which defeats the whole point. - -The 51 controller schemas under `memory/schemas/` therefore **do not move**, even though they are -thin. Thin is what a good syscall table looks like. - -### 6.7 Expected shape after - -~74k LOC of host `memory*` reduces to a kernel-side surface dominated by RPC + tools + policy + -adapters. **Line count is not the goal and not the success metric** — the metric is that -`grep -rn "tinycortex::" src/openhuman/ --include=*.rs` returns hits only under -`memory_adapter/embedded/` and `src/openhuman/tinycortex/`. - ---- - -## 7. Conformance suite - -The golden-workspace parity harness that backs the TinyCortex cutover is promoted to a -**driver conformance suite** — one test corpus, run against any driver: - -- **Tier 1 (mandatory families):** store/get/forget/list/namespaces round-trips, recall ranking - sanity, taint preservation, namespace isolation, export→import fidelity. -- **Tier 2 (per advertised family):** one scenario per family; skipped-with-reason when unadvertised. -- **Tier 3 (policy, driver-independent):** `source_scope` allowlist honoured; out-of-scope source - never returned; redaction applied before an `external` driver sees content; `ExternalSync` taint - stamped on synced ingest; credential never in `Debug`/error output. -- **Tier 4 (differential):** `mirror` mode runs the corpus against both drivers and diffs results — - the acceptance gate for adding a new driver. - -`tinycortex` must pass Tiers 1–4 with results identical to pre-change.

Open questions - -1. **Does `documents` (the namespace tier) stay mandatory in practice?** Several host surfaces - (`store_skill_sync`, profiles, episodic log) assume it. If an external driver cannot provide it, - do we bind a `composite` with an embedded `documents` shard, or degrade those surfaces? - *Leaning:* composite — keep documents embedded, delegate recall/ingest. Decide in M5. -2. **Where do embeddings live for an external driver?** If the backend embeds server-side we must - not double-embed. *Proposal:* a capability flag `embeds_internally`; when set, the kernel skips - the embedding provider for that path. -3. **Multi-user / multi-workspace binding** — one bind per process, or per workspace? *Leaning:* - per workspace, since `global.rs` already rebinds on active-user switch. -4. **Sync ownership.** Sources/credentials/scheduling stay host, but a backend like Supermemory - has its own connectors. Do we allow a driver to advertise `owns_sources` and let the host step - back?
