From 5f6cb0f0276a26713b90709a9de10e8a22a03bf6 Mon Sep 17 00:00:00 2001 From: Greg Kaleka Date: Tue, 20 Oct 2026 14:35:32 -0400 Subject: [PATCH 1/6] Remove tools.allow_tasks and the model task tools Remove the section opt-in that offered the model four task tools copied from the Lua task functions, because a model needs a different shape than futures that can outlive their section. The scheduler loses every path that served only those tools: the built-in tool route, parking a model call until one of its tasks ends, and the queue of task-end notices pushed into the next model round. The four tool names are no longer reserved, so a catalog tool can take one. The Lua task functions keep their behavior, and the task origin type stays. - `crates/runvil-internal/engine/src/execute/scheduler/builtins.rs` is deleted with `builtins-schemas.rs`, `builtins-tests.rs`, `await_tasks.rs`, and `notices.rs`. `ToolRoute` loses `Builtin`, `DispatchTarget` loses `Builtin`, and `ToolCallDispatch` keeps only `Issued` and `Answered`. - `Chain` drops `awaiting` and `task_notices`, so `wake_waiter` always delivers the member as a `JoinAny` answer and now returns nothing. - `cancel_task` returns `Result<()>` and becomes private to `waits.rs`, and `prepare_timer` becomes private to `timer.rs`. - `task_lifecycle` and `terminals_per_started_task` move unchanged into `fixtures.rs` for the fanout and run-termination suites. - `offer_refusal` no longer refuses the names `task`, `task_cancel`, `task_status`, and `await_tasks`; `tool_route` sends them to a local tool or the catalog like any other name. - `prepare_chat` no longer pushes notices onto the list, so an empty list is refused before any round, as `an_empty_list_raises_before_any_round` pins. - `dispatch_cancel` no longer queues a notice when the author cancels a task. - `drop_timer` wakes its waiter with the interrupted `JoinAny` error in every case. - `a_section_tools_table_holds_only_its_api_and_its_round_advertises_only_the_offered_tool` pins the exact keys of a section's `tools` table and a `models.loop` round that advertises only `tools_echo`. - `unofferable_tool` becomes `hidden/shape` with a scalar schema, since a wire name no longer makes a tool unofferable. - `abandon_owned_tasks` still leaves `TaskOrigin::Model` tasks out of the leaked ids.

Leave the tasks, leave the the tasks object there with its functions". + - Remove model-origin tasks entirely, including `TaskOrigin`, `Event::TaskStarted.origin`, the notices queue, and the `tasks.pending` origin filter, even though this changes the facade and the recorded event shape. Rationale: with the `task` tool gone nothing creates a model-origin task, so this code would be unreachable. User choice: "Remove all". + - `tasks.pending` takes no argument and rejects any argument. Rationale: silently ignoring an old `origin` filter would change results without telling the author or a model reading the error; the message names the expected and actual shapes. + - Release the four names from the Engine's reserved set. Rationale: no built-in owns them; the future subagents Plugin will put its tools under its own Plugin id. + - Rely on serde's default unknown-field handling for old logs instead of a compatibility shim. Rationale: `Event` already accepts unknown fields and the run-log reader is untyped. +- Rejected alternatives: + - Keep `TaskOrigin` on the public and recorded surfaces and reject `"model"` in the parser.

Integration tests compile as one binary per crate under `tests/suite/` (`main.rs` plus one module per topic, e.g. `crates/runvil/tests/suite/`, `crates/harness/tests/suite/`). Prompt fixtures are Markdown under `tests/prompts/{valid,invalid,execution}/` loaded with `include_str!`. Shared test support sits in a `test_support` module (e.g. `crates/runvil-internal/engine/src/test_support/`: rig, scenario, seeded, temp_root, recording). Engine tests use no sleeps, wall clock, timeouts, or OS entropy; randomness comes from a printed fixed seed; temp dirs are named from test name, pid, and a counter. TypeScript tests are `node --test` `.mjs` files in each package's `test/` directory (`crates/workshop/{ui,look,platform}/test/`) or `src/**/*.test.mjs`, using jsdom. Nextest config is `.config/nextest.toml` (60s slow timeout; whisper suites in a `heavy` group). +- Directory map: `crates/` holds every crate; its top level is the public and shared layer (`runvil` Engine facade with `public-api.txt`, `runvil-plugin` Plugin API, `harness`, `harness-gateway-client`, `plugin-web`/`plugin-mcp`/`plugin-user-input`, `gateway-api-types`/`gateway-api-discovery` shared gateway vocabulary, `shared-error-source`/`shared-loopback`, `shared-ui` TypeScript+CSS package, and `build-*` tooling: `build-xtask` structural checks and `xtask api`, `build-ceiling` 500-line file check run by every crate's `build.rs`, `build-ui` esbuild helper, `build-workshop`, `build-user-guide`, `build-llama-cuda`). Manifestless private containers: `crates/runvil-internal/` (Engine: `types`, `parser`, `lua`, `vfs`, `model-client`, `engine`), `crates/harness-internal/runner`, `crates/gateway/` (`app` binary, `config`, `config-ui`, `local`, `logging`, `progress`, `protocol`, `routing`, `cloud-providers`, `web-search`, and `stt/{api,engine,backend-whisper,whisper-ffi}`), `crates/workshop/` (Rust: `desktop` Tauri app, `server`, `server-api`, `agents`, `gateway`, `menu`, `protocol`, `registry`, `run-log`, `status`, `support`, `user-state`, `workspace`; npm workspace: `ui`, `look`, `platform`).

Engine (`runvil`, `runvil-*`) depends on no gateway, workshop, or Harness crate; `runvil` alone reaches `runvil-internal/*` (plus `runvil-plugin`, which uses `runvil-types`/`runvil-vfs`). Harness (`harness` -> `harness-runner`, `runvil`, `runvil-plugin`) names only `runvil` and `runvil-plugin` outside its family; only `harness` reaches `harness-internal/`. `plugin-*` depend only on `runvil-plugin`, `shared-*`, and outside libraries; only `harness-gateway-client` (-> `harness`, `plugin-web`, `runvil`) may name a Plugin crate among Engine/gateway/Harness crates. Gateway crates depend on no runvil, workshop, or Harness crate; outsiders reach it only via `gateway-api-types`/`gateway-api-discovery`; `gateway-stt` is the stt subsystem's public member. Workshop crates use only the public gateway pair; `workshop-server` is the Host, depending on `harness`, `harness-gateway-client`, the `plugin-*` crates, `runvil`, `runvil-plugin`, and its workshop siblings; the `workshop` desktop app depends on no workshop crate but `workshop-server-api`, which depends only on `workshop-server`. `shared-*` depend on no product crate.

Task start events, task status, and spawn requests stop carrying an origin, and every task left running when its owner ends now counts as leaked. The pending-tasks call loses its filter: any argument is the call's error naming its type, and the protocol parser owns that check rather than the Lua wrapper. The task notice event and its emitter are removed because nothing produces them any more. Logs written before this change still load, since the extra origin key on a task start entry is ignored. - `TaskOrigin` and `ParseTaskOriginError` are deleted from the types crate and the facade's `ids` module; `public-api.txt` drops them along with `Event::TaskStarted::origin` and every `Event::TaskNotice` field. - `Request::Pending` becomes a unit variant. `tasks_pending` passes its argument through as `argument`, and `parse_pending` turns any non-nil value into the call's error, so the Lua shim holds no check of its own. - `prepare_spawn` and `dispatch_spawn` lose their `origin` parameter and with it their `clippy::too_many_arguments` expectations; `live_tasks_of` and `dispatch_pending` lose their origin filter. - `on_task_notice` and `TaskNoticeReport` leave the recording test support together with the event they forwarded. - `abandon_owned_tasks` counts every abandoned live task as leaked, so any task left live turns its owner's success into `tasks_live`. The `Error::TasksLive` message now reads "chain ended with tasks still live", without "author". - `parse_pending` refuses an argument with exactly `tasks.pending takes no arguments, got `; tests cover `{}`, `{ origin = 'author' }`, and a string at the parser, and both tables through `pcall` in a run. - `task_status_table` no longer sets an `origin` key, and `status_reports_a_parked_task_and_then_a_finished_one` pins the full key list of both status tables. - `shim_origin` is gone, so `parse_spawn` no longer reads or requires an `origin` key on a spawn yield. - `a_task_started_line_carrying_an_origin_still_reads_back` pins that an older `task_started` line carrying `"origin":"author"` still deserializes.

From: Greg Kaleka Date: Tue, 20 Oct 2026 18:19:17 -0400 Subject: [PATCH 4/6] Pin abandon reasons and refuse any pending argument Removing the model task tests left no run-level test of why a running task is abandoned when its owner ends, so three chain-end tests and a phrase test now pin each reason. The pending shim now refuses an argument in any position, and helpers that only the removed notice code needed are narrowed. - `run_abandoning_a_running_task` holds a child on a model round while its owner returns, fails, or exhausts its tool loop, and asserts the child's observations are exactly `TaskStarted` then `TaskAbandoned` with `OwnerReturned`, `OwnerFailed`, or `ToolLoopExhausted`. - `every_abandon_reason_renders_its_own_phrase` pins the `why()` text of all five `AbandonReason` variants. - `tasks_pending` scans every argument and passes the first non-nil one to the parser, so `tasks.pending(nil, {})` raises the same error as `tasks.pending({})`. - `MessageList::push` is `pub(crate)`, and `live_tasks_of` and `task_status` are private to `waits.rs`.
