The channel graph reads Provider-trait capability methods before building the model: `supports_native_tools`, `supports_vision`, `effective_context_window` (**async**), `telemetry_provider_id`. `ProviderModel::profile()` already carries tool_calling / image_in / streaming / context-window, so a `ChatModel`-accepting `build_turn_models` is feasible — but the **async context-window resolution** and **telemetry id** must be re-homed (into the factory at ChatModel construction, or passed as params). Net: one atomic change across ~30 files (incl. ~10 test files) on the live channel/session turn path — must land as its own reviewed PR with streaming/cost/multimodal behavior-parity testing (the flagged regression surface: #4460 thread_id task-locals, $0-turn cost, tool timeline). `routing/provider.rs::IntelligentRoutingProvider` stays a `Provider` impl (provider-stack member, Phase-3 → `ModelRegistry`); it gets wrapped via `chat_model_from_provider` at the producer boundary. **BLOCKER (found while executing):** the harness cannot hold `Arc` in Phase 1 as the plan assumed. `build_turn_models` needs the raw `Provider` for (a) workload-route projection — `routes::build_route_models(provider: &Arc)` re-instantiates a `ProviderModel` per tier alias with distinct model strings + per-route `with_vision`/`with_reasoning` flags, which a single baked `ChatModel` cannot re-alias — and (b) the separate-error-slot summarizer. The crate `ChatModel` trait exposes no `as_any`/downcast, so the `Provider` cannot be recovered from an `Arc`. Therefore the true harness inversion is gated on **Phase 3** (replace `RouterProvider`/route-projection with the crate `ModelRegistry`), an upstream `vendor/tinyagents` change — not host-only. Achievable host-only step instead: wrap the harness-held `Arc` in a seam-owned newtype (e.g. `tinyagents::TurnModelSource`) so no `agent/` code names the `Provider` trait and all Provider handling is confined to the seam + factory, making the Phase-3 swap seam-local. **PROGRESS:** `docs/tinyagents-phase3-router-registry-design.md` records the corrected premise (router→registry already crate-wired in `assemble_turn_harness`; no upstream gap; work is host-only Motion A). `TurnModelSource` (pub seam type) landed + `TurnModels` extended with `provider_id`/`context_window`/`native_tools`/`supports_vision`. **Channel/bus turn path fully migrated** (commit `30c7dfd92`): `AgentTurnRequest.provider → turn_model_source`; `run_channel_turn_via_graph` reads caps off the built crate models; channels/triage producers wrap at the bus boundary; lib + the 3 bus integration tests green; zero behavior change. **Subagent-runner path migrated** (commit `8db888712`): `agent_graph::AgentTurnRequest.provider → turn_model_source`; `run_subagent_via_graph` takes the source (reads vision/native-tool caps + telemetry id off the built models, resolves context window via the source); `SubagentCheckpoint` cap-hit summary now runs on a crate `ChatModel` (via `TurnModelSource::build_summarizer`) instead of `provider.chat`; runner wraps its resolved `subagent_provider` at both dispatch sites. Core lib green; changed files clean under `--lib --tests`; zero behavior change. **Agent session path migrated** (commit `9112330b9`): `Agent`/`AgentBuilder`, `ParentExecutionContext`, and `ChatTurnGraph` hold a `TurnModelSource`/built `TurnModels`; core builds the tiered model set up front (reads vision off it), `ParentExecutionContext` carries the source, and the streaming cap-hit checkpoint keeps `provider.chat` via a `source.provider()` escape hatch (crate `ChatModel::invoke` has no delta sink). Extract tool migrated (commit `6106ced83`). **Motion A is structurally complete:** no agent-harness struct (`Agent`, `AgentBuilder`, `ParentExecutionContext`, `ChatTurnGraph`, both `AgentTurnRequest`s) holds `Arc`; both Cargo worlds green; zero behavior change. `TurnModelSource` gained `is_local_provider()` + a `provider()` escape hatch used only at seam-boundary resolution sites. **Remaining `dyn Provider` in `agent/` (Motion B, not Motion A):** provider-*resolution/build* boundaries that construct a provider to wrap into a source — `session/builder/factory.rs` (`create_chat_provider`/`create_routed_provider`), `subagent_runner/ops/provider.rs::resolve_subagent_provider` (kept `Arc` to avoid churning its 9 unit tests), `tools/delegate.rs`, `triage/routing.rs`, and the builder `.provider()/.provider_arc()` setters — plus test files.

The flip **re-runs the same gate** the `Provider` path applies (`enforce_local_only_inference` + `verify_session_active`), so it cannot bypass privacy mode or the session requirement. Temperature rides the per-call `ModelRequest` (parity with managed). **Loopback error handling defers to upstream:** an upstream merge (`b709a993…`/`04ffc029…`) replaced the earlier `..._offline_trips_halt_guard` test with `cron_agent_job_short_loopback_send_error_stays_retryable` — i.e. an offline local provider now **stays retryable** (it may be transiently starting up). So the transient cron `{e:#}` cause-chain surfacing + the `is_non_retryable` loopback fast-fail were reverted, and the host stays pinned at `7c6e81a` (before [tinyagents#50](https://github.com/tinyhumansai/tinyagents/pull/50) `error_source_chain`) so the crate-native local error does not surface the `connection refused` errno the classifier would trip on. #50 remains a good crate improvement but is deliberately **not consumed** here to keep loopback retryable. | +| Bespoke (managed backend, `claude_code`, `claude_agent_sdk`, `openai_codex`) | stay host `ChatModel` impls | **HOST-OWNED** — subprocess / `/v1/responses` / query-param auth have no crate equivalent; never route through `crate_openai`. | + +**Crate dependency landed:** [tinyagents#49](https://github.com/tinyhumansai/tinyagents/pull/49) +adds `OpenAiModel::{with_native_tool_calling, with_vision, with_default_provider_options}` ++ a pure `merge_provider_options` (baked defaults merged under per-call +options; a non-object override passes through so validation still rejects it). +Merged onto crate `v1.8.0` main as `7c6e81a`; crate tests: 61 openai unit tests +pass (55 + v1.8.0's #45/#46); `cargo fmt --check` clean.
