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. Legacy + `session_raw/DDMMYYYY/` layout still resolves for resume. +5. **Usage rollups.** `read_thread_usage_summary` → + `ThreadUsageSummary` + `SubagentArchetypeUsage`. + +Public surface: 26 items — `SessionTranscript`, `TranscriptMeta`, +`DisplaySessionTranscript`, `DisplayRecord`, `DisplayMessage`, +`CompactionMarker`, `TurnUsage`, `MessageUsage`, `ThreadUsageSummary`, +`SubagentArchetypeUsage`, plus `write_transcript`, `append_transcript_turn`, +`append_interrupted_partial`, `read_transcript`, `read_transcript_display`, +`read_transcript_legacy_md`, `read_thread_usage_summary`, +`find_root_transcript_for_thread(_in_dir)`, `resolve_keyed_transcript_path(_in_dir)`, +`resolve_new_transcript_path`, `find_latest_transcript(_in_subdir)`. + +### 2.4 Consumers + +**24 files across 5 domains** import `transcript::`: `agent`, `threads`, +`session_import`, `learning`, `migrations`. Notable non-agent callers: + +- `threads/transcript_view/project.rs` — the derived-view projection +- `threads/turn_state/mirror.rs` — `find_root_transcript_for_thread`, `append_interrupted_partial` +- `threads/ops.rs` — `read_thread_usage_summary` +- `session_import/{ops,convert,live}.rs` — external session import +- `learning/transcript_ingest/mod.rs` — lesson extraction +- `migrations/phase_out_profile_md.rs` + +This is the **transcript-derived-view architecture**: `session_raw` JSONL is the +source of truth, `turn_state` is a derived cache.

What the crate already ships + +`vendor/tinyagents` v2.1.0: + +| Crate capability | Module | Relevance | +| --- | --- | --- | +| `ChatHistory` trait — `messages(thread_id) -> Vec`, `append`, `replace`, `clear` | `harness::memory::types:48` | **The direct analogue.** Thread-scoped conversation history surviving across runs. | +| `InMemoryChatHistory`, `StoreChatHistory`, `ShortTermMemory` (trim policy), `MemoryScope` | `harness::memory` | Backends + short/long-term layering | +| `Store` — kv (`get`/`put`/`delete`/`list`) **plus an append-only stream API**: `append(stream, value) -> u64`, `read_from(stream, offset)`, `len(stream)` | `harness::store` | The stream half is a closer structural match to the JSONL log than `ChatHistory` is | +| `InMemoryStore`, `FileStore`, `StoreRegistry` | `harness::store` | Backends | +| `Checkpointer`, `FileCheckpointer`, `SqliteCheckpointer`, `DurabilityMode` | `graph::checkpoint` | Superstep state snapshots — **different concern**, not a transcript | + +**So OpenHuman is not missing a home; it has a second implementation.** That is +the whole argument for this work. + +### 3.1 Gap table — what crate `ChatHistory` cannot express today + +| OpenHuman semantic | Crate equivalent | Gap | +| --- | --- | --- | +| Append-only log, never rewrite | `Store::append`/`read_from` (stream API) | present on `Store`, **absent from `ChatHistory`** (`replace` is a bulk overwrite) | +| Compaction record with `replacement` set | — | **missing** | +| `interrupted:true` partials, skipped on model read | — | **missing** | +| Dual read paths (model-context replay vs display-order) | — | **missing** — `messages()` is single-view | +| Cumulative `_meta` totals appended per turn | — | **missing** | +| Schema versioning + unknown-line tolerance | — | **missing** (a policy, easily added) | +| `.md` companion render | — | **host** — product surface, never upstream | +| Stem naming, latest/resume discovery, legacy dir fallback | — | **host** — OpenHuman workspace layout | +| Thread/subagent usage rollups | `harness::usage`, `harness::cost` | partial; the archetype rollup is product | + +`ChatHistory` is a **strictly weaker interface** than what OpenHuman needs. 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.

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. Kernel/driver split criterion + +One question decides where any file lives: + +> **Would a build whose only driver is a third-party external backend still need this file?** + +- **Yes → kernel.** RPC schemas and ops, agent-tool definitions, `SecurityPolicy` and policy + guards, provenance/taint, scope and redaction, credentials and keychain, schedulers and cron, + the event bus, config mapping, the driver registry and transport adapters, export/import. +- **No → driver crate.** Storage engines, indexes, chunking, embeddings pipelines, retrieval and + ranking, summary trees, job engines, source readers and parsers, provider-specific + normalisation, on-disk formats and migrations. + +This is a sharper rule than "is it product policy or engine logic", which is how the +2026-07-28 cutover evaluation landed on keeping several engine-shaped modules in the host. Under +the kernel criterion those modules are **implementation of the default driver** and belong to it — +see the memory spec §6 for the concrete re-disposition. + +--- + +## 5.

Definition of done (kernel layer) + +1. `src/core/subsystem/` exists: `Driver`, `DriverClass`, `DriverHealth`, `Capabilities`, + `SubsystemRegistry`, `Guard`, and the `[subsystems.*]` config mapping. +2. Binding happens once at `CoreBuilder` time; a failed bind falls back to the embedded default, + emits a `DomainEvent`, and is visible in `_status`. +3. Controller registration in `src/core/all.rs` is filtered by the bound driver's capability set, + the same way it is filtered by `DomainSet` today. +4. Agent-tool assembly is filtered by the same set. +5. `Guard` is the only path from product code to a driver; a test asserts no direct driver call + site exists outside the registry module. +6. `openhuman subsystems` CLI + `subsystems_status` RPC list slot, bound driver, class, health, + contract version, and capabilities. +7. Docs: `gitbooks/developing/architecture/kernel.md` describes the model; `AGENTS.md` gains a + "adding a subsystem driver" checklist. + +## 7. Risks + +- **Capability sprawl.** Every optional trait is a branch in RPC registration and tool assembly. + Mitigation: capability families are coarse (≤10 per subsystem) and adding one requires a + contract minor bump plus a both-ways test. +- **Guard bypass.** Mitigation: drivers are private to the registry module; a lint test greps for + out-of-module construction. +- **Parity regressions.** Mitigation: the golden-workspace harness that already backs the + TinyCortex cutover is promoted to the general conformance suite (§ memory spec 7). +- **Over-abstraction.** Mitigation: memory ships end-to-end and a second real driver exists before + a second subsystem is cut over.

Direction decided by the maintainer on 2026-07-28 +after two rounds of pushback; this document plans the move rather than +re-arguing it. The open questions below are *how*, not *whether*. +**Scope:** relocate `src/openhuman/agent/` (152 files, 70,530 LOC) into +`vendor/tinyagents` as a generic agent runtime, with OpenHuman's coupling +expressed as trait injection. +**Supersedes:** the "permanent host" dispositions for `builder/`, `turn/`, +`runtime.rs`, and `types.rs` in +`2026-07-28-agent-session-transcript-to-tinyagents-design.md` §6, and the +`agent/ remainder — STAYS` row in `tinyagents-migration-plan-2026-07-22.md` §7. +Those rows are reopened by this decision and must be updated in the ledger. + +--- + +## 1. Why this is feasible (the enabling fact) + +The earlier objection was dependency direction: `agent/` reaches 45 OpenHuman +domains, so relocating it appeared to force a GPL-redistributed crate to import +Composio, `SecurityPolicy`, and `memory_store`. + +That objection assumes the code moves *as written*. It does not have to, +because **the crate is already generic over a host-supplied state type**: + +```rust +pub struct AgentHarness { … } +pub trait Tool: Send + Sync { … } +pub trait ChatModel: Send + Sync { … } +pub trait Middleware: Send + Sync { … } +``` + +`State` is the injection vehicle. A relocated agent runtime does not import +`crate::openhuman::memory` — it is generic over a `State` that *provides* +memory, and OpenHuman supplies the impl. The crate already ships **18 extension +traits** on exactly this pattern (`ChatModel`, `Tool`, `ChatHistory`, `Store`, +`AppendStore`, `Summarizer`, `EmbeddingModel`, `VectorStore`, `ResponseCache`, +`WorkspaceIsolation`, `HarnessEventJournal`, `HarnessStatusStore`, +`EventListener`, `Middleware`, `ModelMiddleware`, `ToolMiddleware`, +`ModelBaseCall`, `ToolBaseCall`). This move adds ~10 more of the same kind. It +is not a new architecture; it is more of the one already in use. + +The GPL/crates.io concern also narrows correctly: the constraint is that no +*OpenHuman product logic* is published, not that no agent runtime is. Traits and +a generic loop are publishable; `provider_role_for`'s `subconscious` routing and +the `integrations_agent` dispatcher override are not — they become host impls. + +--- + +## 2.

A generic runtime cannot import OpenHuman's config +schema.

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 durable conversation record to +become crate-owned, 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. + +> **Corrected 2026-08-03.** This section previously said the decision was +> "**Option B** of the transcript spec: the `session_raw` JSONL format becomes +> crate-owned public API". It is not. The in-flight migration (issue #4249, +> `src/openhuman/session_import/`) converges on the crate's **`Store` / +> `AppendStore` journal**, not on promoting the legacy JSONL layout to crate +> API. The legacy `session_raw/*.jsonl` format stays a host implementation +> detail and is retired once readers move; it never becomes public crate +> surface. See the Phase 2 note in §5. + +--- + +## 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: [`docs/spec/host-capability-traits-rfc.md`](https://github.com/tinyhumansai/tinyagents/blob/main/docs/spec/host-capability-traits-rfc.md) +in the `tinyagents` repo (vendored here at `vendor/tinyagents/`; linked by URL +because the link checker does not check out submodules) +— 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.

The session 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 reads as `Unavailable`, never `Divergence`. These + 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 the soak is that a warning means something. +- **`session_shadow_reads` now defaults ON**, starting the parity soak. Safe to + default on because it is observation-only: legacy stays authoritative, the + probe runs on a background task once per *resume* (not per turn), a store-read + failure degrades to `Unavailable`, and `OPENHUMAN_SESSION_SHADOW_READS=0` is a + kill switch. Worst case of a bad soak is log noise, not a broken resume. + +**Remaining for Phase 2** — and the reason it is not yet done: + +1. **Soak.** Collect `[session_shadow_read]` divergence rates from real + workspaces across one release. There is no data yet, so nothing below is + justified. +2. **04.2 — flip readers**, gated on the same flag, only once the soak is clean. +3. Retire the legacy writer once reads have run on the store for a release. + +**Do not skip to 2.** The whole design of this phase is that the reader flip is +bought with evidence, and the evidence does not exist until a release has +shipped with the probe on. + +**Phase 3 — Config mapping (§4.1 Option A).** — *in progress (2026-08-02)* +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. + +Landed so far — foundation only, nothing repointed yet: + +- `tinyagents::harness::config` — `SessionConfig`, `TurnConfig`, `ToolConfig`, + `MemoryLimits`, `RequiredOutput`, `ToolDispatcher`. Inert (serde + std only), + defaults pinned to OpenHuman's current values. +- `src/openhuman/tinyagents/config.rs` — `session_config_from` plus + `apply_team_models` / `apply_delegate`, following the + `tinycortex::config::memory_config_from` precedent. Split three ways because + OpenHuman's model pins are **not global**: `Config::teams` is keyed by team + and `Config::agents` by delegate, so one flat mapper would have to invent the + model for a session. +- 23 tests across both sides. The load-bearing one is + `default_config_maps_to_the_crate_defaults`, which fails if the two default + sets ever drift. + +`ToolDispatcher` is an enum where the host has a `String`. The four accepted +spellings are `auto` / `native` / `xml` / `pformat` — **not** the +`auto`/`native`/`parsed` triple a reasonable person would guess. An unknown +value maps to `Auto` with a warning rather than failing: the host's own schema +lets a typo through validation, so refusing to build the session would turn a +cosmetic config error into an agent that cannot run. + +#### Repointing: what the "37 files" actually decomposes into + +The 37-file figure counts every `agent/` production file with a qualified +`config::` path. **Only ~19 are in the moving set** — the rest (`host_runtime`, +`bus`, `triage/`, `schemas`, `multimodal`, `prompts/`, `agent/tools/`, +`archivist/`, `progress_tracing/`) stay host-side per §3 and *should* keep +reading `Config`; they are the mapper's callers. Repointing them would be +actively wrong. Within the moving set: **41 qualified refs**, which split into +three very different problems. + +**1. Ambient config loads — 11 sites. Not a repoint; a signature refactor.** +*(Done 2026-08-02 — 11 sites → 2 genuine + 1 boundary snapshot.)* + +`Config::load_or_init().await` appeared 11 times inside code slated to move. +A generic runtime has no config file and no `load_or_init`, so these could not +be pointed at a struct — the config had to be **threaded in from the caller**. + +`load_or_init` is **not cached**: it re-resolves the config dirs and re-reads +`config.toml` on every call. `run_typed_mode` called it six times, so one +sub-agent spawn hit the disk six times and could observe six *different* +configs mid-spawn. `run_subagent` now takes a single snapshot +(`LoadedConfig = Result, String>`) and hands it down. + +`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 each site preserve its original failure behaviour. The +snapshot is taken **after** `tier_gate_decision`: `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 got the same treatment: `build_subagent_context_mw` now +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 rather than silently falling back +to defaults. The four graph tests pass `None`, which makes them hermetic — they +previously read whatever `config.toml` was on the developer's machine. + +**Scope correction: `task_dispatcher/` is not in the moving set.** §3 lists it +beside `dispatcher.rs`, both mapping to `harness::{tool_calling, hooks}`. That +conflates two unrelated modules. `dispatcher.rs` parses tool calls out of model +output and is genuinely generic. `task_dispatcher/` is a task-**card board** +dispatcher reaching `task_sources`, `threads`, `web_chat`, `todos`, `profiles` +and `scheduler_gate` — product logic that stays host-side. Its three +`load_or_init` calls are boundary code and are correct as they are. **§3's row +should be split.** + +Two loads remain in moving files, both host-boundary code that gets extracted +rather than moved: + +- `session/turn/tools.rs:123` — Composio integration fetch. Config is *already* + threaded via the session's `integration_runtime_config` (set in + `factory.rs:1280`); this is only the fallback when a session is built through + the raw setter path. Composio is host product logic and becomes a `Tool` impl + in Phase 4, so the fallback was left rather than risk silently disabling + integration fetching for setter-built sessions. +- `harness/definition.rs:781` — `load_for_default_workspace()`, a convenience + constructor with exactly one caller: `src/core/agent_cli.rs:415`. It is a CLI + boundary helper that stays host-side when `definition.rs` moves. + +**2. Blocked on Phase 2 — the session cannot drop `AgentConfig` yet.** + +The session reads only **9 distinct `AgentConfig` fields**, 7 of which the crate +structs already cover. The two that do not — `session_dual_write` and +`session_shadow_reads` (`session/turn/session_io.rs`) — are *transcript* +live-store migration flags. They have no crate home until Phase 2 decides where +the transcript lives, so `Agent.config: AgentConfig` has to stay for now. + +Adding a crate `SessionConfig` *alongside* it was considered and rejected: +`session/runtime.rs:181` mutates `self.config.max_tool_iterations` after build +(the iteration-cap override), so two configs would silently diverge on exactly +the field most read. One source of truth or none. + +**3. Blocked on Phase 4 — `builder/factory.rs`.** + +`factory.rs` reaches 21 domains and is going to be *split* into host trait impls, +not moved verbatim. Repointing its `Config` usage now is rework. + +#### Done in this pass + +`RequiredOutputContract` → crate `RequiredOutput`, the one clean type swap +available: `harness/required_output.rs` (pure logic, no host domains) and +`session/turn/session_io.rs`, converting at the read site in +`session/turn/core.rs` via `tinyagents::config::required_output_from`. The +crate type gained `all_keys()` with semantics identical to the host's, including +the subtle one — a blank `block_key` makes the contract inert *even when +`required_keys` lists siblings*. The 12 existing `required_output` tests pass +unchanged against the crate type, which is the proof the swap is behaviour- +preserving. + +The mapper was also split into per-section functions (`turn_config_from`, +`tool_config_from`, `memory_limits_from`, `apply_agent_config`) because the +session builder takes a **per-agent `AgentConfig` override** — mapping only from +the global `Config` would have discarded it and run every agent on the global +limits. + +#### Revised remaining work + +1. ~~Thread config through the ambient-load sites.~~ **Done 2026-08-02.** +2. After Phase 2: replace `Agent.config` with crate config; migrate the two real + external `agent_config()` consumers (`agent_orchestration/parent_context/`, + `subconscious/session.rs`). +3. After Phase 4: `factory.rs`, and the Composio fetch in `session/turn/tools.rs`. +4. Split §3's `task_dispatcher/` + `dispatcher.rs` row — only the latter moves. + +> **Test note.** `openhuman::agent::` needs `RUST_MIN_STACK=16777216` or +> `session::tests::turn_dispatches_spawn_subagent_through_full_path` overflows +> the stack (already flagged in §6).

Each wires one crate trait to the real OpenHuman +domains, with policy enforced adapter-side. `agent/` **does not call them yet**, +so the exit criterion is still at 295 — writing the adapters and repointing the +callers are two separate pieces of work and only the first is done. + +Two defects were found and fixed at integration, both of the kind that compiles +cleanly and fails silently: + +- **`security_gate`: a channel `RequireApproval` verdict was resolving to + `Allow`.** The mapping returned "no verdict" on the theory the call would fall + through to the approval park — but the park is reached only 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 routed to + the park, and **denied** when no approval gate exists (the one place this + adapter set denies where the legacy middleware allows, argued in the module + header). Pinned by `require_approval_never_silently_allows_a_plain_tool`. +- **`experience_store`: cross-agent record collision.** The domain's + `stable_experience_id_for_profile` hashes task + tool sequence + outcome + + profile and deliberately **excludes `agent_id`**; the native capture hook is + protected only incidentally, by always supplying a real tool sequence. This + adapter has none to supply, so two agents recording the same task with the + same outcome collided on one id and `put` upserted — the second writer + silently destroying the first's record. The agent id is now folded into the + hashed tool-sequence slot. + +**Remaining for Phase 4 — repointing. Investigated 2026-08-04 and found +blocked, not merely hard.** Four findings, each measured: + +**1. The exit criterion counts the wrong code.** Of the 118 non-adapter-layer +refs in `session/`, roughly two-thirds are not consumption at all: + +| Where | Refs | What it is | +| --- | ---: | --- | +| `builder/` (factory 29, setters 12, mod 3, helpers 2) | 46 | assembly — becomes the trait *impls*, per §3 | +| `types.rs` | 16 | field type annotations — the injection points themselves | +| `runtime.rs` | 13 | session state management (e.g. `rebuild_tool_policy_session`) | +| `turn/` | 40 | the only genuine runtime consumption | +| misc | 3 | | + +Driving `session/` "down to the adapter layer only" therefore cannot happen by +repointing: most of those refs **are** the adapter layer. The honest metric is +`turn/`'s ~40. + +**2. The session distributes handles more than it consumes them.** All 11 uses +of `self.memory` hand the `Arc` to a collaborator (the memory +loader, the context loader, `AgentExperienceStore`) rather than calling recall +or store. Swapping the field to `Arc` would break those +collaborators, which need the full domain interface. The memory seam cannot be +repointed until they move behind traits too. + +**3. No capability trait fits an existing call shape 1:1.** Checked all ten. +`ContextComposer::compose_system_prompt` returns a `String`, but the turn needs +structured `LearnedContextData` to feed its own `SystemPromptBuilder`, so +adopting it means moving the whole prompt assembly into the adapter — the same +work as Phase 5, not a repoint. `ToolOutcomeClassifier`'s only host consumer is +`progress_tracing/`, which §3 **deletes** rather than moves. `subconscious` in +`session/` is type annotations in `factory.rs` only. + +**4. Four adapters cannot be constructed from session state.** + +| Adapter | Constructor needs | Session has | +| --- | --- | --- | +| `AgentMemory`, `ExperienceStore` | `Arc` | yes (`memory_arc()`) | +| `ToolOutcomeClassifier` | nothing | yes | +| `ProgressSink` | `Sender` | yes | +| `LearningSink` | `Vec>` | yes | +| **`BudgetGate`, `ContextComposer`, `ModelResolver`** | **`Arc`** | **no — holds `AgentConfig`; full `Config` only as the optional `integration_runtime_config`** | +| **`SecurityGate`** | **`Arc`** + tool sets | tool sets yes, **policy no** | + +That `Arc` gap is precisely the Phase 3 blocker, which means: + +> **The program is now a dependency chain, and its head is elapsed time.** +> Phase 4's repointing needs the session to carry a full `Config` → that is +> Phase 3's session-config swap → which is blocked on Phase 2 rehoming +> `session_dual_write` / `session_shadow_reads` → which is blocked on the +> parity soak, and the soak needs a *shipped release* to produce data. +> +> So §5's claim that Phase 4 "delivers most of the architectural value with +> none of the relocation risk" and is a legitimate stopping point holds only +> for the **adapters**, which are done.

That is the one +piece of Phase 4 repointing that can proceed now, and it is worth doing before +the soak completes so the rest is a short step rather than a long one. + +**21 `TODO(phase4)` markers** remain across the adapters, each naming a domain +surface that was not reachable. They are honest gaps, not stubs pretending to +work; the notable ones are `AgentMemory::thread_summary` (no host-authored +per-thread prose rollup exists) and `SecurityGate::screen_input` never returning +`Redacted` (OpenHuman can detect PII but exposes no public text-rewriting +helper). + +**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}`.

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.

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/`).

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`.

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.

Host capability adapter: [`AgentMemory`] over OpenHuman's memory stack. +//! +//! This is `docs/specs/plan-agents.md` Phase 4 for the memory seam. The agent +//! runtime is being made generic over its host, so it must stop reaching into +//! [`crate::openhuman::memory`] directly. Instead the crate declares +//! [`AgentMemory`] and this module is the single place OpenHuman's memory +//! domains meet it. +//! +//! # Domains adapted +//! +//! - [`crate::openhuman::memory`] — the `Memory` trait, `MemoryEntry`, +//! `MemoryCategory`, `MemoryTaint`, `RecallOpts`. +//! - `crate::openhuman::agent::tinyagents::retriever::recall_through_facade` — the +//! existing retrieval facade (issue #4249, 09.2). Recall goes **through** it +//! rather than calling `Memory::recall` directly, so this adapter inherits +//! OpenHuman's ranking engine verbatim, the `path_scope` dedupe rule, and the +//! `AgentEvent::MemoryLoaded` emission instead of forking a second recall path. +//! - [`crate::openhuman::memory::store::safety`] — `sanitize_text`, the +//! conservative secret + PII scrubber, applied on the way out of recall and on +//! the way in to `remember`. +//! - [`crate::openhuman::memory::agent::memory_loader::MemoryCitation`] — the +//! host's citation shape, rendered down to the opaque string the crate wants. +//! +//! # Where the policy lives, and why it lives *here* +//! +//! The trait's contract is explicit: items returned by [`AgentMemory::recall`] +//! have **already** been scope-filtered and redacted, and the runtime is +//! forbidden from re-ranking or re-filtering them. That makes this adapter the +//! last place OpenHuman's guards can run, so all of them run here: +//! +//! - **Scope is host-chosen, never runtime-chosen.** `RecallRequest`'s +//! `agent_id` / `thread_id` / `limit` are documented as *hints about the +//! caller*, not instructions about storage. The namespace comes from this +//! adapter's own configuration and is never derived from a runtime field — +//! the same "the tool has no namespace parameter" discipline +//! `crate::openhuman::flows::memory_tools` uses to keep a flow inside its +//! own sandbox. A thread hint may only *narrow* the query (it becomes +//! `RecallOpts::session_id`), never widen it, and `cross_session` stays a +//! wiring-time decision that defaults to `false`. +//! - **A defensive second scope pass.** Even with `session_id` set, recalled +//! rows are re-checked host-side and any row carrying a *different* session is +//! dropped. Unscoped rows (`session_id: None`) stay visible, matching the +//! crate's own `InMemoryAgentMemory` scoping semantics. The pass is skipped +//! when `cross_session` is on: that flag was already sent to the backend as an +//! instruction to return other sessions' rows, so a same-session re-test would +//! throw away everything the widening returned and reduce the opt-in to a +//! no-op. The guard exists to catch a backend that ignored a *narrowing* +//! request, and widening is the opposite of that. +//! - **Redaction is unconditional.** Every returned `text` and every citation +//! snippet goes through `sanitize_text`, so no raw store row reaches the +//! runtime. A row that the scrubber changed is logged (counts only, never +//! content). +//! - **Provenance is stamped host-side.** `NewMemory` deliberately carries no +//! taint field, so this adapter supplies one and writes through +//! `Memory::store_with_taint`. 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". [`OpenHumanAgentMemory::with_taint`] lets a wiring +//! site that genuinely knows better relax it. +//! +//! # Contract mismatches resolved +//! +//! 1. **`remember` returns an id, `Memory::store` does not.** OpenHuman's write +//! path is an upsert keyed by `(namespace, key)` and hands nothing back. To +//! keep the id space coherent with the ids `recall` returns, this adapter +//! reads the row back with `Memory::get` after storing and returns the +//! backend's own `MemoryEntry::id`, falling back to the synthetic +//! `"{namespace}/{key}"` handle when the read-back finds nothing. +//! 2. **`MemoryItem::citation` is an opaque `String`.** The host's +//! `MemoryCitation` is a structured UI contract; leaking its JSON would +//! couple the crate to OpenHuman's frontend. It is built for real (so the +//! seam uses the host type rather than a parallel one) and then rendered to a +//! single flat `openhuman:memory/...` line by [`render_citation`]. +//! 3. **`thread_summary` returns `Ok(None)`.** See the method docs — OpenHuman +//! has no host-authored per-thread prose rollup to return, and the trait +//! forbids synthesizing a substitute. +//! 4. **`NewMemory::tags` are dropped.** The trait calls them advisory and +//! explicitly permits a host to discard them; OpenHuman's `Memory::store` has +//! no tag column, and folding runtime-supplied labels into the namespace or +//! key would turn an advisory hint into a scope, which the trait forbids. +//! They are logged and otherwise ignored. + +use std::sync::Arc; + +use async_trait::async_trait; +use tinyagents::error::{Result as TaResult, TinyAgentsError}; +use tinyagents::harness::host::{AgentMemory, MemoryId, MemoryItem, NewMemory, RecallRequest}; +use tinyagents::harness::ids::ThreadId; + +use crate::openhuman::memory::agent::memory_loader::MemoryCitation; +use crate::openhuman::memory::store::safety::sanitize_text; +use crate::openhuman::memory::{Memory, MemoryCategory, MemoryEntry, MemoryTaint, RecallOpts}; +use crate::openhuman::util::truncate_with_ellipsis; + +/// Namespace agent-produced memories are written to and recalled from when the +/// wiring site does not choose one. +/// +/// `"global"` is `tinycortex::memory::GLOBAL_NAMESPACE`, which is also what +/// `RecallOpts { namespace: None, .. }` falls back to — so the default is the +/// same namespace the rest of OpenHuman's recall already reads. +pub const DEFAULT_AGENT_MEMORY_NAMESPACE: &str = "global"; + +/// Number of items recalled when the runtime supplies no `limit`. +/// +/// Matches `DefaultMemoryLoader`'s default `limit` so this seam injects the same +/// amount of context the legacy loader did. +pub const DEFAULT_RECALL_LIMIT: usize = 5; + +/// Hard ceiling on how many items one recall may return, whatever the runtime +/// asks for. +/// +/// The trait documents `limit` as an upper bound the *host* may lower for its +/// own reasons; this is that reason.

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::cron::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::cron::scheduler_gate; +use crate::openhuman::inference::provider::types::UsageInfo; +use crate::openhuman::inference::tokenjuice::AgentTokenjuiceCompression; +use crate::openhuman::platform::cost::{self, BudgetCheck}; + +/// 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.

The `SOUL.md` / `IDENTITY.md` / `HEARTBEAT.md` bootstrap files under +//! `src/openhuman/agent/prompts/` are loaded (and synced to the workspace) +//! by `IdentitySection` inside `SystemPromptBuilder::build`, so this adapter +//! never reads them itself. +//! * [`crate::openhuman::config::Config`] — supplies `workspace_dir`, +//! `action_dir`, the default model, and the `agents_md_enabled` gate. +//! * [`crate::openhuman::desktop::app_state::peek_cached_current_user_identity`] — the +//! non-secret `id`/`name`/`email` triple. Deliberately read through the +//! *cache peek*, which is the accessor that strips credential material; this +//! adapter must not reach for a richer user record to fill the prompt. +//! +//! Prompt assembly is **not** reimplemented here. Everything this file does is +//! translate a [`TurnContextRequest`] into a `PromptContext` and hand it to the +//! existing `SystemPromptBuilder::with_defaults()` chain — the same chain +//! `agent::harness::session::turn::context::build_system_prompt` uses. 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 implementation of the TinyAgents **agent catalogue** seam. +//! +//! Adapts two OpenHuman domains onto +//! [`tinyagents::harness::host::DefinitionRegistry`]: +//! +//! * [`crate::openhuman::agent::harness::definition::AgentDefinitionRegistry`] — +//! the harness registry of built-in ([`load_builtins`](crate::openhuman::agent::registry::agents::load_builtins)-parsed +//! `agent.toml`) +//! and workspace-override agent definitions, plus the config-backed +//! user-authored fallback +//! ([`crate::openhuman::agent::registry::find_custom_in_config`] → +//! [`crate::openhuman::agent::registry::definition_from_registry_entry`]). +//! * [`crate::openhuman::agent::profiles::AgentProfile`] — the active personality, +//! whose `allowed_tools` list is a **restriction** on the resolved +//! definition's tool surface. +//! +//! This is `docs/specs/plan-agents.md` Phase 4. The crate-side +//! [`AgentDefinition`] is inert (`serde` + `std`); OpenHuman's harness +//! definition is far richer (prompt builders, sandbox mode, iteration policy, +//! TokenJuice profile, turn graph). Only the six fields the turn loop can act +//! on cross the seam; everything else stays host-side by design. +//! +//! # Contract mismatches resolved here +//! +//! **1. Absence must never be an error.** OpenHuman's own catalogue relies on +//! this: `orchestrator/agent.toml` lists `mcp_agent` in `subagents` even in a +//! build with the `mcp` feature off, and both existing resolution sites +//! tolerate it (`collect_orchestrator_tools` warns and skips; +//! [`validate_tier_hierarchy`](crate::openhuman::agent::registry::agents::validate_tier_hierarchy) explicitly `continue`s past unknown ids). So +//! `OpenHumanDefinitionRegistry::resolve` returns `Ok(None)` for every miss +//! and this adapter has no error path at all. +//! +//! **2. Declared vs authorized subagents.** The crate's +//! `AgentDefinition::subagents` is only what an agent *declares*; +//! `delegates_for` must return the **authorized** set. OpenHuman's authority is +//! the tier hierarchy, so `delegates_for` applies +//! [`validate_tier_transition`](crate::openhuman::agent::harness::definition::validate_tier_transition) +//! — the same single source of truth +//! [`validate_tier_hierarchy`](crate::openhuman::agent::registry::agents::validate_tier_hierarchy) walks at boot — per declared pair. A `Worker` +//! parent yields an empty list; a tier-illegal child is dropped. Unknown child +//! ids are **kept**, matching both [`validate_tier_hierarchy`](crate::openhuman::agent::registry::agents::validate_tier_hierarchy)'s `continue` and +//! the trait's note that an authorized id may still fail to resolve. +//! +//! **3. `ToolScope::Wildcard` has no crate representation.** The crate models +//! tools as an explicit `Vec` in which **empty means unrestricted**, +//! matching the session builder ("an empty `visible` set means no filter" — +//! `agent/harness/session/builder/factory.rs`). So an unrestricted wildcard +//! agent maps to an empty `tools` vec. +//! +//! That one value must not be made to carry three meanings. Three distinct +//! situations would otherwise all collapse onto "empty", and each would read +//! back as *every tool*: +//! +//! * a named scope configured with **no** tools, +//! * a named scope whose every entry the denylist removed, +//! * a wildcard scope carrying a denylist the crate cannot express. +//! +//! [`ResolvedScope`] therefore models wildcard-ness explicitly and never infers +//! it from emptiness. A genuinely empty scope emits +//! [`PROFILE_NO_TOOLS_SENTINEL`] — an unregistered name that matches nothing — +//! and a wildcard-with-denylist is materialized against +//! [`Self::with_registered_tools`], failing closed when that is absent. +//! +//! **4. `SubagentEntry::Skills` entries are omitted.** A `{ skills = "*" }` +//! entry is not an agent id — it collapses into the single +//! `delegate_to_integrations_agent` tool. Emitting a synthetic id here would +//! invent a delegate the host never authorized. +//! +//! **5. Profile model overrides are deliberately not applied.** +//! `AgentProfile::model_override` has no verified host consumer on the +//! definition path (the web-chat `model_override` request parameter is a +//! different value, applied to `Config::default_model`), and the model seam is +//! `ModelResolver`'s, not the catalogue's.

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. +//! +//! The **order** matters as much as the filter. The domain truncates to the +//! requested `max_hits` before this adapter ever sees the rows, so filtering +//! a truncated page would let a busier agent's highly-scored records occupy +//! every slot and leave this recall empty while matching attempts sat just +//! below the cut. So the query over-fetches (`candidate_hits`) and the +//! truncation happens *after* the ownership filter, which is what makes +//! `max_hits` mean "up to N of **this** agent's attempts". +//! 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::{ + retrieve_across_stores, 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`].

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::agent::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. +//! +//!

(`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.

Host capability: turns the crate's coarse [`ProgressEvent`] stream into +//! OpenHuman's richer [`AgentProgress`] events. +//! +//! Adapts `crate::openhuman::agent::progress` (the `AgentProgress` UI contract) +//! for `tinyagents::harness::host::ProgressSink`. This is Phase 4 of +//! `docs/specs/plan-agents.md`. +//! +//! # Why this file is the boundary +//! +//! `AgentProgress` is the **host's** UI contract — the chat processing +//! timeline, the subagent drawer, the cost footer and the trace exporter all +//! read it. 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, but not every event is equally droppable.** Token +//! deltas use `try_send` and are *dropped* when the bridge is behind, per the +//! crate's "dropping progress events is always preferable to slowing the +//! turn" rule. Lifecycle events (`TurnStarted`, `ToolCallStarted`, +//! `TurnCompleted`) are not interchangeable with them: the bridge is a state +//! machine, so a lost one leaves a tool row stuck in `running` forever rather +//! than costing a UI tick. They therefore wait up to +//! [`LIFECYCLE_SEND_GRACE`] for room — bounded, never indefinite, because an +//! unbounded await on this shared channel is the documented subagent-stall +//! flake (`tool_progress.rs::emit`). Nothing here blocks a turn or panics. +//! * **The coarse stream has no iteration boundary.** `AgentProgress` carries a +//! 1-based `iteration` on almost every variant; `ProgressEvent` has no +//! equivalent. The sink derives one **per run**: a *batch* of consecutive +//! `ToolCall`s is one iteration, and model output (`Token`) closes the batch +//! so the next call opens a new one. Counting every call instead would report a +//! turn that requested two tools in parallel as three iterations. Still a +//! *lower bound* — two sequential tool batches with no tokens between them are +//! indistinguishable from one parallel batch. See the `TODO(phase4)` below. +//! * **One sink may serve several runs.** `Arc` is +//! explicitly shared across concurrent sub-runs, so all counters are keyed by +//! [`RunId`] and only the **first run seen** projects top-level `TurnStarted` / +//! `TurnCompleted`. A shared counter would let a child's tool calls renumber +//! the parent's iterations, and a child's `Finished` would tell the progress +//! bridge the whole request had completed while other runs were still +//! emitting. +//! * **No `ToolCallCompleted` is ever emitted, and none can be.** The crate's +//! `ProgressEvent` has five variants and none of them reports a tool +//! *finishing* — there is no success flag, no output, no duration anywhere in +//! the coarse stream. `AgentProgress::ToolCallCompleted` requires all three. +//! Synthesising one would mean asserting `success: true` for a tool that may +//! have failed, which corrupts the timeline and the trace exporter rather than +//! merely leaving them incomplete. So tool rows stay `running` until the +//! crate grows a completion event; 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. Fabricating a +//! `model: ""` / `total_usd: 0.0` update would silently under-report in the +//! chat cost footer, so the usage is logged and only `TurnCompleted` is +//! forwarded. + +use std::collections::HashMap; +use std::sync::atomic::{AtomicU64, Ordering}; +use std::sync::Mutex; + +use async_trait::async_trait; +use tokio::sync::mpsc::error::TrySendError; +use tokio::sync::mpsc::Sender; + +use tinyagents::harness::host::{ProgressEvent, ProgressSink}; + +use crate::openhuman::agent::progress::AgentProgress; + +/// How long a **lifecycle** event may wait for room on a full channel. +/// +/// Sized to ride out the transient window a burst of token deltas opens, while +/// staying far below anything a user or a parent turn would perceive as a +/// stall.

Host [`SecurityGate`] — OpenHuman's answer to "may this tool run?" and +//! "may this text enter the model context?". +//! +//! This is `docs/specs/plan-agents.md` Phase 4 for the most policy-sensitive +//! seam in the set. The tinyagents runtime holds *no* authority: it asks, and +//! obeys. Everything it would otherwise have to guess at lives on this side — +//! the autonomy tier, the command classifier, the per-channel tool policy, the +//! human-in-the-loop approval park, and the prompt-injection screen. +//! +//! # Domains adapted +//! +//! - [`crate::openhuman::security::policy`] — [`SecurityPolicy`], its +//! [`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. **This gate owns approval, and must be the only thing that prompts.** +//! `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. The tempting shape — park here +//! with the plain [`ApprovalGate::intercept`] and let +//! `ApprovalSecurityMiddleware` record the terminal row — does not work: the +//! middleware can only obtain an id by issuing its *own* `intercept_audited`, +//! which raises a **second** approval card for a call the user already +//! approved. A one-shot approval does not settle that second request, so the +//! call would wait out a second TTL and then be denied. +//! +//! So ownership is consolidated here. This adapter calls +//! `intercept_audited`, stashes the id under the call id, and exposes +//! [`OpenHumanSecurityGate::take_audit_request_id`] for the executor to drain +//! and hand to [`ApprovalGate::record_execution`]. **A runner that installs +//! this gate must not also compose `ApprovalSecurityMiddleware`'s approval +//! step** — the two are alternatives, not layers. The session-allowlist +//! shortcut yields no id and needs no terminal row. +//! 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::tools::status::classify) turns raw tool error +//! text into a [`ClassifiedFailure`](crate::openhuman::tools::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. +//! +//! **4. A timeout cannot be assumed safe to repeat.** `Timeout` is the one +//! failure class where "the call failed" and "the call succeeded but the reply +//! was lost" are indistinguishable from the outside. For a tool with an +//! external effect — sending an email, moving money, running a shell command — +//! re-dispatching a timed-out call can commit the effect a second time. The +//! crate's `RetryableFailure` is an assertion that repeating is *acceptable*, +//! so it may only be made about a tool the host has positively identified as +//! side-effect free — declared through +//! [`OpenHumanToolOutcomeClassifier::with_retry_safe_tools`] as an +//! **allowlist**. An allowlist rather than the inverse, because +//! `Tool::external_effect()` is arg-less: `ShellTool` and the TinyPlace raw +//! tool classify their effect from *arguments* (`external_effect_with_args`) +//! and leave the arg-less variant at the default `false`, so a denylist built +//! from it would admit precisely the tools that must be excluded. Absent the +//! allowlist, timeouts stay permanent — the safe direction, since a lost retry +//! costs an iteration while a duplicated payment cannot be undone. +//! +//!
