## Summary Implements the two automation run endpoints from issue #399, backed by a significant refactor of the worker control channel from stdin JSONL to a WebSocket-based pub/sub bus. ## What changed ### New API endpoints (`automations.rs`) - `GET /automations/{id}/runs` — lists cached runs filtered to those linked to the given automation ID, sorted newest-first, with `page[limit]`/`page[offset]` pagination and the standard `{ data, meta }` envelope. - `POST /automations/{id}/runs` — requires `RequiredRunToolActor` auth, checks that the automation exists and has an enabled API trigger (returning 409 with `automation_api_trigger_disabled` otherwise), materializes the run manifest, and delegates to the shared `create_run_from_manifest` helper with a fully-populated `AutomationRef`. ### `enabled_api_trigger()` helper (`fabro-automation`) A new method on `Automation` encapsulates the "automation is enabled **and** has an enabled API trigger" check, keeping the handler clean. ### Worker control channel: stdin JSONL → WebSocket bus The most significant structural change is how the server delivers control messages (answers, cancel, pause/unpause, steer, pair events) to running workers: | Before | After | |---|---| | Server pipes JSONL lines to worker stdin | Server publishes to `WorkerControlBus`; worker connects via WebSocket | | Worker reads stdin on a blocking OS thread | Worker manages a reconnecting WebSocket with ping/pong liveness | | No delivery deduplication | `AppliedWorkerControlDeliveryIds` deduplicates replayed frames | | No reconnect / resume | Worker reconnects with exponential backoff; replays from last applied cursor | The `LocalWorkerControlBus` replaces the old `mpsc` channel and stdin pipe. `RunAnswerTransport::Subprocess` is renamed `Worker` and holds a `run_id` + `Arc<dyn WorkerControlBus>` instead of a channel sender. Worker stdin is now `Stdio::null()`. New control messages `RunPause` / `RunUnpause` are added to the protocol, wired through to `RunControlState`. ### Plan Summary - Add `enabled_api_trigger()` to `Automation`. - Implement `list_automation_runs` and `create_automation_run` handlers; route them under `/automations/{id}/runs`. - Expose `create_run_from_manifest` from the runs handler for reuse. - Add `RequiredRunToolActor` extractor. - Replace stdin JSONL worker control with `WorkerControlBus` + WebSocket reconnect loop in the CLI worker. - Add integration tests for all 409/201 cases, run persistence, listing filters, pagination, and sorting. ### Fabro Details <details> <summary>Ran 8 stages in 51m 5s for $21.34</summary> | Stage | Duration | Cost | Retries | |---|---|---|---| | start | 0s | – | 0 | | toolchain | 1s | – | 0 | | preflight_compile | 2m 8s | – | 0 | | preflight_lint | 2m 23s | – | 0 | | implement | 20m 52s | $13.05 | 0 | | simplify_opus | 11m 5s | $5.70 | 0 | | simplify_gpt | 5m 0s | $2.60 | 0 | | verify | 9m 4s | – | 0 | | **Total** | **51m 5s** | **$21.34** | **0** | </details> <details> <summary>Ran <code>ImplementPlan.fabro</code> (11 nodes and 14 edges)</summary> ```dot digraph ImplementPlan { graph [ goal="Implement and simplify", model_stylesheet=" * { model: claude-opus-4-7; } " ] rankdir=LR start [shape=Mdiamond, label="Start"] exit [shape=Msquare, label="Exit"] toolchain [label="Toolchain", shape=parallelogram, script="command -v cargo >/dev/null || { curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y && sudo ln -sf $HOME/.cargo/bin/* /usr/local/bin/; }; cargo --version 2>&1", max_retries=0] preflight_compile [label="Preflight Compile", shape=parallelogram, script="cargo check -q --workspace 2>&1", max_retries=0] preflight_lint [label="Preflight Lint", shape=parallelogram, script="cargo +nightly-2026-04-14 clippy -q --workspace --all-targets -- -D warnings 2>&1", max_retries=0] fix_lints [label="Fix Lints", prompt="The preflight lint step failed.
