Here's a summary of the cleanup applied based on the three parallel reviews:\n\n## Cleanup Summary\n\n**Correctness fix:**\n- **Lost-wakeup race in `LocalWorkerControlBus`**: `local_subscription_task` could miss a publish that landed between message-read and `notify.notified()` registration. Now registers `notified()` before inspecting the stream and uses the proper enable-before-check pattern.\n\n**Memory / efficiency:**\n- **Removed unbounded `applied_ids: HashSet`** in the CLI worker control task. The server cursor + monotonic IDs already guarantee no replay; kept a simple `last_applied_id == frame.id` check as defense-in-depth.\n- **Dropped `Arc>>` for `last_applied_id`**: it's owned by a single task. Now a plain `&mut Option`, removing two lock-held-across-await sites per loop iteration.\n- **Pinned the `Sleep` once outside the WS loop** in both server and worker handlers, calling `Pin::reset` instead of allocating a new `Sleep` per iteration.\n- **Replaced O(N) `iter().filter().cloned()` over the retained deque** with `partition_point` + tail iteration in `collect_messages_from`.\n\n**Reuse / consolidation:**\n- **Moved `WORKER_CONTROL_WS_PING_INTERVAL`, `WORKER_CONTROL_WS_LIVENESS_TIMEOUT`, `WORKER_CONTROL_INVALID_CURSOR_REASON`, `WORKER_CONTROL_PONG_TIMEOUT_REASON`** into `fabro-interview::control_protocol` so server and worker share one source of truth.\n- **Used `axum::extract::ws::close_code::AWAY` / `POLICY` constants** instead of raw `1001` / `1008` literals on the server.\n\n**Dead code removal:**\n- **Removed `WorkerControlBus::backend_name`** trait method (only used by a tautological test) and the associated `#[allow(dead_code)]` and `Hash` derive on `WorkerControlMessageId`.\n- **Removed the single-variant `WorkerCommandStdin` enum** + constant + tautological test; inlined `Stdio::null()`.\n- **Deleted `#[cfg(test)] parse_worker_control_line` and `apply_worker_control_line`** wrappers; rewrote the four tests to call `apply_worker_control_message` directly with typed envelopes.\n\n**Verification:**\n- `cargo nextest run -p fabro-server worker_control` — 15/15 pass\n- `cargo nextest run -p fabro-interview` — 62/62 pass\n- `cargo nextest run -p fabro-cli runner` — 33/33 pass\n- `cargo nextest run -p fabro-server --test it --features test-support lifecycle` — 3/3 pass\n- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings` — clean\n- Two pre-existing `pause_run_*` / `unpause_run_sets_pending_control` failures verified to exist before this cleanup (confirmed via `git stash`).\n\n**Findings I deliberately skipped** (not high-impact enough or would require API surface changes outside this cleanup):\n- Splitting `WorkerControlBusError` into publish/subscribe error types\n- Replacing `BoxFuture` with `async_trait` (style consistency)\n- Moving WS-URL construction onto `ServerTarget` (touches `fabro-client`, `fabro-sandbox`)\n- Adopting `fabro_util::backoff::BackoffPolicy` (small benefit; existing hand-rolled is correct)\n- Collapsing `WorkerControlSocket` enum into `Box` (works but tungstenite's `from_raw_socket` generic constraints make this fiddly)\n- Per-run inner mutex sharding in the bus (premature for local single-node)\n- `cleanup_worker_control_bus_for_run` spawn-per-call (sync-fast-path optimization; correctness fine)", - "internal.run_id": "01KSNP2DXVS2TD1HEASQAFBGFK", - "thread.verify.current_node": "fixup", - "graph.goal": "# Worker Control Bus Implementation Plan\n\n> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** Replace the server-to-worker stdin JSONL control pipe with a backend-agnostic worker control bus, implemented now with a local in-memory bus and delivered to workers over a worker-initiated WebSocket.\n\n**Architecture:** API handlers publish `WorkerControlEnvelope` messages to a `WorkerControlBus`; the worker WebSocket route subscribes to that bus and forwards ordered delivery frames to the worker. Workers track the last fully applied delivery id and reconnect with `?after=` after any unexpected WebSocket close. The first backend is an in-process `LocalWorkerControlBus` for local and single-node deployments. A Redis Streams backend must fit behind the same trait later, but Redis is explicitly out of scope for this implementation plan.\n\n**Tech Stack:** Rust, Axum WebSockets, tokio-tungstenite, UnixStream, async-trait or boxed async traits, tokio channels/Notify, worker JWT auth, existing `WorkerControlEnvelope`.\n\n---\n\n## Key Decisions\n\n- WebSocket fully replaces stdin control. Do not keep stdin JSONL as a compatibility path.\n- The worker protocol stays identical across local, single-node, ECS, and later SaaS deployments.\n- The server-side delivery backend is the only thing that varies by deployment.\n- This plan implements only `LocalWorkerControlBus`.\n- This plan does not add Redis dependencies, Redis configuration, Redis tests, Redis health checks, or Redis runtime behavior.\n- Redis Streams are covered only as a future backend contract so the local design does not paint us into a corner.\n- There is no `Latest` cursor. The first worker connection starts at the beginning of the run's retained control stream; reconnects resume after the worker's last fully applied delivery id.\n- Every WebSocket text frame is a delivery frame with an id and envelope. The worker advances `last_applied_id` only after applying the envelope.\n- Workers reconnect forever while the local run is not terminal, using backoff from 100ms, doubled after each failure, capped at 5s.\n- The worker must complete its first control-stream connection before starting or resuming workflow execution. Temporary first-connect failures wait and retry; they do not start a control-disconnected run.\n- Invalid cursor means the bus can no longer prove replay correctness. The worker treats it as fatal control-channel loss and fails/aborts the run as infrastructure failure, not as user cancellation.\n- WebSocket liveness is handled at the WebSocket layer with explicit ping/pong and timeout logic. The bus does not know about heartbeats.\n- ECS task launch, ECS stop/reconciliation, Redis-backed multi-node delivery, and remote hard-kill behavior are follow-up work.\n\n## Redis Fit Later: Out of Scope Now\n\nRedis should later implement the same `WorkerControlBus` API introduced here.\n\n- `publish(run_id, envelope)` maps to `XADD fabro:run:{run_id}:control ...`.\n- First `subscribe(run_id, Start)` maps to `XREAD BLOCK ... STREAMS fabro:run:{run_id}:control 0-0`.\n- Reconnect `subscribe(run_id, After(id))` maps to `XREAD BLOCK ... STREAMS fabro:run:{run_id}:control {id}`.\n- Local message ids use an opaque string format such as `local:1`; Redis message ids can use Redis stream ids such as `1716810000000-0`.\n- The WebSocket route should not care whether the subscription source is local memory or Redis.\n- The worker should not care whether the frame came from a local bus or Redis.\n- Redis trimming/retention, consumer groups, per-tenant key naming, TLS/auth, reconnect-after-redeploy semantics, and SaaS config validation are not part of this plan.\n\n## Proposed File Structure\n\n- Create `lib/crates/fabro-server/src/worker_control/mod.rs`\n - Owns the server-side control bus abstraction and re-exports the local backend.\n- Create `lib/crates/fabro-server/src/worker_control/bus.rs`\n - Defines `WorkerControlBus`, `WorkerControlDelivery`, `WorkerControlMessageId`, `WorkerControlCursor`, and bus errors.\n- Create `lib/crates/fabro-server/src/worker_control/local.rs`\n - Implements `LocalWorkerControlBus` using process memory.\n- Create `lib/crates/fabro-server/src/server/handler/worker_control.rs`\n - Adds the worker-only WebSocket route.\n- Modify `lib/crates/fabro-server/src/server.rs`\n - Adds the bus to `AppState`, replaces subprocess `RunAnswerTransport` sends with bus publishes, removes stdin pumping.\n- Modify `lib/crates/fabro-server/src/server/handler/mod.rs`\n - Registers the worker control route.\n- Modify `lib/crates/fabro-server/src/server/handler/lifecycle.rs`\n - Sends pause/unpause/cancel controls through the transport/bus where appropriate.\n- Modify `lib/crates/fabro-cli/src/commands/run/runner.rs`\n - Replaces stdin reading with worker WebSocket client handling.\n- Modify `lib/crates/fabro-cli/Cargo.toml`\n - Adds `tokio-tungstenite` as a direct dependency if needed.\n- Modify `lib/crates/fabro-interview/src/control_protocol.rs`\n - Adds pause/unpause control messages and a transport delivery frame type shared by server and worker.\n\n## Task 1: Define the Control Bus Contract\n\n**Files:**\n- Create: `lib/crates/fabro-server/src/worker_control/mod.rs`\n- Create: `lib/crates/fabro-server/src/worker_control/bus.rs`\n- Modify: `lib/crates/fabro-server/src/lib.rs`\n\n- [ ] Add a private `worker_control` module in `fabro-server`.\n- [ ] Define `WorkerControlMessageId` as an opaque cloneable id rather than a numeric type.\n- [ ] Define `WorkerControlCursor` with `Start` and `After(WorkerControlMessageId)` variants.\n- [ ] Define `WorkerControlDelivery { id: WorkerControlMessageId, envelope: WorkerControlEnvelope }`.\n- [ ] Define `WorkerControlBus` with async `publish(run_id, envelope)` and `subscribe(run_id, cursor)` methods.\n- [ ] Make `subscribe` return a stream-like receiver owned by the caller, so the WebSocket handler can forward messages without knowing the backend.\n- [ ] Define explicit bus errors for closed backend, unavailable backend, invalid cursor, and publish timeout.\n- [ ] Document in code comments that `Start` maps to Redis stream id `0-0` and `After(id)` maps to Redis `XREAD` after that id, but do not add Redis code.\n- [ ] Add unit tests for id equality/debug formatting and cursor parsing from the optional `after` query parameter.\n- [ ] Test that absent `after` parses as `WorkerControlCursor::Start`.\n- [ ] Test that present `after=local:42` parses as `WorkerControlCursor::After(...)`.\n- [ ] Run `cargo nextest run -p fabro-server worker_control`.\n\n## Task 2: Implement the Local In-Memory Bus\n\n**Files:**\n- Create: `lib/crates/fabro-server/src/worker_control/local.rs`\n- Test: `lib/crates/fabro-server/src/worker_control/local.rs`\n\n- [ ] Implement `LocalWorkerControlBus` as `Arc>>`.\n- [ ] Store messages per run in insertion order with a monotonic local sequence id.\n- [ ] Wake active subscribers when `publish` appends a message.\n- [ ] Support `subscribe(run_id, Start)` for first worker startup; it must replay retained messages from the beginning of the run control stream.\n- [ ] Support `subscribe(run_id, After(id))` so reconnect uses the same API that later maps to Redis `XREAD`.\n- [ ] Allow `publish` before the worker subscribes; retained messages must be visible to the first `Start` subscriber.\n- [ ] Trim retained local messages to a bounded per-run size so a disconnected local worker cannot grow memory without bound. Use a named constant with initial value 1024 messages per run.\n- [ ] Return a clear `invalid cursor` error when a subscriber asks for an id that has been trimmed or belongs to a different local stream.\n- [ ] Add a cleanup method for terminal runs so completed/cancelled runs can release retained control messages.\n- [ ] Test that messages publish in order.\n- [ ] Test that an active subscriber receives a message published after subscription.\n- [ ] Test that messages published before subscription are replayed to a `Start` subscriber.\n- [ ] Test that `After(id)` receives only later messages.\n- [ ] Test that trimming bounds retained messages and reports an invalid old cursor.\n- [ ] Run `cargo nextest run -p fabro-server worker_control`.\n\n## Task 3: Add Control Bus to Server State\n\n**Files:**\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Test: `lib/crates/fabro-server/src/server/tests.rs`\n\n- [ ] Add `worker_control_bus: Arc` to `AppState`.\n- [ ] Construct `LocalWorkerControlBus` in normal server state initialization.\n- [ ] Add a test-only way to inject a fake or local bus without exposing test helpers to production builds.\n- [ ] Keep demo/in-process execution behavior unchanged unless it currently depends on subprocess control.\n- [ ] Add a state construction test proving the default bus is local and available.\n- [ ] Run `cargo nextest run -p fabro-server worker_control`.\n\n## Task 4: Extend the Control Protocol\n\n**Files:**\n- Modify: `lib/crates/fabro-interview/src/control_protocol.rs`\n- Test: `lib/crates/fabro-interview/src/control_protocol.rs`\n\n- [ ] Add `WorkerControlEnvelope::pause_run()` and `WorkerControlEnvelope::unpause_run()` constructors.\n- [ ] Add `WorkerControlMessage::RunPause` serialized as `\"run.pause\"`.\n- [ ] Add `WorkerControlMessage::RunUnpause` serialized as `\"run.unpause\"`.\n- [ ] Add `WorkerControlDeliveryFrame { id: String, envelope: WorkerControlEnvelope }` as the WebSocket text-frame payload shared by server and worker.\n- [ ] Add round-trip serde tests for both new messages.\n- [ ] Add round-trip serde tests for `WorkerControlDeliveryFrame`.\n- [ ] Run `cargo nextest run -p fabro-interview control_protocol`.\n\n## Task 5: Share Worker Message Handling\n\n**Files:**\n- Modify: `lib/crates/fabro-cli/src/commands/run/runner.rs`\n- Test: `lib/crates/fabro-cli/src/commands/run/runner.rs`\n\n- [ ] Split `apply_worker_control_line(...)` into parsing and `apply_worker_control_message(...)`.\n- [ ] Route WebSocket delivery frames through `apply_worker_control_message(...)`.\n- [ ] Route `run.pause` to `RunControlState::request_pause()`.\n- [ ] Route `run.unpause` to `RunControlState::request_unpause()`.\n- [ ] Add a small in-memory applied-id dedupe set in the worker control task;

Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** Replace the server-to-worker stdin JSONL control pipe with a backend-agnostic worker control bus, implemented now with a local in-memory bus and delivered to workers over a worker-initiated WebSocket.\n\n**Architecture:** API handlers publish `WorkerControlEnvelope` messages to a `WorkerControlBus`; the worker WebSocket route subscribes to that bus and forwards ordered delivery frames to the worker. Workers track the last fully applied delivery id and reconnect with `?after=` after any unexpected WebSocket close. The first backend is an in-process `LocalWorkerControlBus` for local and single-node deployments. A Redis Streams backend must fit behind the same trait later, but Redis is explicitly out of scope for this implementation plan.\n\n**Tech Stack:** Rust, Axum WebSockets, tokio-tungstenite, UnixStream, async-trait or boxed async traits, tokio channels/Notify, worker JWT auth, existing `WorkerControlEnvelope`.\n\n---\n\n## Key Decisions\n\n- WebSocket fully replaces stdin control. Do not keep stdin JSONL as a compatibility path.\n- The worker protocol stays identical across local, single-node, ECS, and later SaaS deployments.\n- The server-side delivery backend is the only thing that varies by deployment.\n- This plan implements only `LocalWorkerControlBus`.\n- This plan does not add Redis dependencies, Redis configuration, Redis tests, Redis health checks, or Redis runtime behavior.\n- Redis Streams are covered only as a future backend contract so the local design does not paint us into a corner.\n- There is no `Latest` cursor. The first worker connection starts at the beginning of the run's retained control stream; reconnects resume after the worker's last fully applied delivery id.\n- Every WebSocket text frame is a delivery frame with an id and envelope. The worker advances `last_applied_id` only after applying the envelope.\n- Workers reconnect forever while the local run is not terminal, using backoff from 100ms, doubled after each failure, capped at 5s.\n- The worker must complete its first control-stream connection before starting or resuming workflow execution. Temporary first-connect failures wait and retry; they do not start a control-disconnected run.\n- Invalid cursor means the bus can no longer prove replay correctness. The worker treats it as fatal control-channel loss and fails/aborts the run as infrastructure failure, not as user cancellation.\n- WebSocket liveness is handled at the WebSocket layer with explicit ping/pong and timeout logic. The bus does not know about heartbeats.\n- ECS task launch, ECS stop/reconciliation, Redis-backed multi-node delivery, and remote hard-kill behavior are follow-up work.\n\n## Redis Fit Later: Out of Scope Now\n\nRedis should later implement the same `WorkerControlBus` API introduced here.\n\n- `publish(run_id, envelope)` maps to `XADD fabro:run:{run_id}:control ...`.\n- First `subscribe(run_id, Start)` maps to `XREAD BLOCK ... STREAMS fabro:run:{run_id}:control 0-0`.\n- Reconnect `subscribe(run_id, After(id))` maps to `XREAD BLOCK ... STREAMS fabro:run:{run_id}:control {id}`.\n- Local message ids use an opaque string format such as `local:1`; Redis message ids can use Redis stream ids such as `1716810000000-0`.\n- The WebSocket route should not care whether the subscription source is local memory or Redis.\n- The worker should not care whether the frame came from a local bus or Redis.\n- Redis trimming/retention, consumer groups, per-tenant key naming, TLS/auth, reconnect-after-redeploy semantics, and SaaS config validation are not part of this plan.\n\n## Proposed File Structure\n\n- Create `lib/crates/fabro-server/src/worker_control/mod.rs`\n - Owns the server-side control bus abstraction and re-exports the local backend.\n- Create `lib/crates/fabro-server/src/worker_control/bus.rs`\n - Defines `WorkerControlBus`, `WorkerControlDelivery`, `WorkerControlMessageId`, `WorkerControlCursor`, and bus errors.\n- Create `lib/crates/fabro-server/src/worker_control/local.rs`\n - Implements `LocalWorkerControlBus` using process memory.\n- Create `lib/crates/fabro-server/src/server/handler/worker_control.rs`\n - Adds the worker-only WebSocket route.\n- Modify `lib/crates/fabro-server/src/server.rs`\n - Adds the bus to `AppState`, replaces subprocess `RunAnswerTransport` sends with bus publishes, removes stdin pumping.\n- Modify `lib/crates/fabro-server/src/server/handler/mod.rs`\n - Registers the worker control route.\n- Modify `lib/crates/fabro-server/src/server/handler/lifecycle.rs`\n - Sends pause/unpause/cancel controls through the transport/bus where appropriate.\n- Modify `lib/crates/fabro-cli/src/commands/run/runner.rs`\n - Replaces stdin reading with worker WebSocket client handling.\n- Modify `lib/crates/fabro-cli/Cargo.toml`\n - Adds `tokio-tungstenite` as a direct dependency if needed.\n- Modify `lib/crates/fabro-interview/src/control_protocol.rs`\n - Adds pause/unpause control messages and a transport delivery frame type shared by server and worker.\n\n## Task 1: Define the Control Bus Contract\n\n**Files:**\n- Create: `lib/crates/fabro-server/src/worker_control/mod.rs`\n- Create: `lib/crates/fabro-server/src/worker_control/bus.rs`\n- Modify: `lib/crates/fabro-server/src/lib.rs`\n\n- [ ] Add a private `worker_control` module in `fabro-server`.\n- [ ] Define `WorkerControlMessageId` as an opaque cloneable id rather than a numeric type.\n- [ ] Define `WorkerControlCursor` with `Start` and `After(WorkerControlMessageId)` variants.\n- [ ] Define `WorkerControlDelivery { id: WorkerControlMessageId, envelope: WorkerControlEnvelope }`.\n- [ ] Define `WorkerControlBus` with async `publish(run_id, envelope)` and `subscribe(run_id, cursor)` methods.\n- [ ] Make `subscribe` return a stream-like receiver owned by the caller, so the WebSocket handler can forward messages without knowing the backend.\n- [ ] Define explicit bus errors for closed backend, unavailable backend, invalid cursor, and publish timeout.\n- [ ] Document in code comments that `Start` maps to Redis stream id `0-0` and `After(id)` maps to Redis `XREAD` after that id, but do not add Redis code.\n- [ ] Add unit tests for id equality/debug formatting and cursor parsing from the optional `after` query parameter.\n- [ ] Test that absent `after` parses as `WorkerControlCursor::Start`.\n- [ ] Test that present `after=local:42` parses as `WorkerControlCursor::After(...)`.\n- [ ] Run `cargo nextest run -p fabro-server worker_control`.\n\n## Task 2: Implement the Local In-Memory Bus\n\n**Files:**\n- Create: `lib/crates/fabro-server/src/worker_control/local.rs`\n- Test: `lib/crates/fabro-server/src/worker_control/local.rs`\n\n- [ ] Implement `LocalWorkerControlBus` as `Arc>>`.\n- [ ] Store messages per run in insertion order with a monotonic local sequence id.\n- [ ] Wake active subscribers when `publish` appends a message.\n- [ ] Support `subscribe(run_id, Start)` for first worker startup; it must replay retained messages from the beginning of the run control stream.\n- [ ] Support `subscribe(run_id, After(id))` so reconnect uses the same API that later maps to Redis `XREAD`.\n- [ ] Allow `publish` before the worker subscribes; retained messages must be visible to the first `Start` subscriber.\n- [ ] Trim retained local messages to a bounded per-run size so a disconnected local worker cannot grow memory without bound. Use a named constant with initial value 1024 messages per run.\n- [ ] Return a clear `invalid cursor` error when a subscriber asks for an id that has been trimmed or belongs to a different local stream.\n- [ ] Add a cleanup method for terminal runs so completed/cancelled runs can release retained control messages.\n- [ ] Test that messages publish in order.\n- [ ] Test that an active subscriber receives a message published after subscription.\n- [ ] Test that messages published before subscription are replayed to a `Start` subscriber.\n- [ ] Test that `After(id)` receives only later messages.\n- [ ] Test that trimming bounds retained messages and reports an invalid old cursor.\n- [ ] Run `cargo nextest run -p fabro-server worker_control`.\n\n## Task 3: Add Control Bus to Server State\n\n**Files:**\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Test: `lib/crates/fabro-server/src/server/tests.rs`\n\n- [ ] Add `worker_control_bus: Arc` to `AppState`.\n- [ ] Construct `LocalWorkerControlBus` in normal server state initialization.\n- [ ] Add a test-only way to inject a fake or local bus without exposing test helpers to production builds.\n- [ ] Keep demo/in-process execution behavior unchanged unless it currently depends on subprocess control.\n- [ ] Add a state construction test proving the default bus is local and available.\n- [ ] Run `cargo nextest run -p fabro-server worker_control`.\n\n## Task 4: Extend the Control Protocol\n\n**Files:**\n- Modify: `lib/crates/fabro-interview/src/control_protocol.rs`\n- Test: `lib/crates/fabro-interview/src/control_protocol.rs`\n\n- [ ] Add `WorkerControlEnvelope::pause_run()` and `WorkerControlEnvelope::unpause_run()` constructors.\n- [ ] Add `WorkerControlMessage::RunPause` serialized as `\"run.pause\"`.\n- [ ] Add `WorkerControlMessage::RunUnpause` serialized as `\"run.unpause\"`.\n- [ ] Add `WorkerControlDeliveryFrame { id: String, envelope: WorkerControlEnvelope }` as the WebSocket text-frame payload shared by server and worker.\n- [ ] Add round-trip serde tests for both new messages.\n- [ ] Add round-trip serde tests for `WorkerControlDeliveryFrame`.\n- [ ] Run `cargo nextest run -p fabro-interview control_protocol`.\n\n## Task 5: Share Worker Message Handling\n\n**Files:**\n- Modify: `lib/crates/fabro-cli/src/commands/run/runner.rs`\n- Test: `lib/crates/fabro-cli/src/commands/run/runner.rs`\n\n- [ ] Split `apply_worker_control_line(...)` into parsing and `apply_worker_control_message(...)`.\n- [ ] Route WebSocket delivery frames through `apply_worker_control_message(...)`.\n- [ ] Route `run.pause` to `RunControlState::request_pause()`.\n- [ ] Route `run.unpause` to `RunControlState::request_unpause()`.\n- [ ] Add a small in-memory applied-id dedupe set in the worker control task;

Here's a summary of the cleanup applied based on the three parallel reviews:\n\n## Cleanup Summary\n\n**Correctness fix:**\n- **Lost-wakeup race in `LocalWorkerControlBus`**: `local_subscription_task` could miss a publish that landed between message-read and `notify.notified()` registration. Now registers `notified()` before inspecting the stream and uses the proper enable-before-check pattern.\n\n**Memory / efficiency:**\n- **Removed unbounded `applied_ids: HashSet`** in the CLI worker control task. The server cursor + monotonic IDs already guarantee no replay; kept a simple `last_applied_id == frame.id` check as defense-in-depth.\n- **Dropped `Arc>>` for `last_applied_id`**: it's owned by a single task. Now a plain `&mut Option`, removing two lock-held-across-await sites per loop iteration.\n- **Pinned the `Sleep` once outside the WS loop** in both server and worker handlers, calling `Pin::reset` instead of allocating a new `Sleep` per iteration.\n- **Replaced O(N) `iter().filter().cloned()` over the retained deque** with `partition_point` + tail iteration in `collect_messages_from`.\n\n**Reuse / consolidation:**\n- **Moved `WORKER_CONTROL_WS_PING_INTERVAL`, `WORKER_CONTROL_WS_LIVENESS_TIMEOUT`, `WORKER_CONTROL_INVALID_CURSOR_REASON`, `WORKER_CONTROL_PONG_TIMEOUT_REASON`** into `fabro-interview::control_protocol` so server and worker share one source of truth.\n- **Used `axum::extract::ws::close_code::AWAY` / `POLICY` constants** instead of raw `1001` / `1008` literals on the server.\n\n**Dead code removal:**\n- **Removed `WorkerControlBus::backend_name`** trait method (only used by a tautological test) and the associated `#[allow(dead_code)]` and `Hash` derive on `WorkerControlMessageId`.\n- **Removed the single-variant `WorkerCommandStdin` enum** + constant + tautological test; inlined `Stdio::null()`.\n- **Deleted `#[cfg(test)] parse_worker_control_line` and `apply_worker_control_line`** wrappers; rewrote the four tests to call `apply_worker_control_message` directly with typed envelopes.\n\n**Verification:**\n- `cargo nextest run -p fabro-server worker_control` — 15/15 pass\n- `cargo nextest run -p fabro-interview` — 62/62 pass\n- `cargo nextest run -p fabro-cli runner` — 33/33 pass\n- `cargo nextest run -p fabro-server --test it --features test-support lifecycle` — 3/3 pass\n- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings` — clean\n- Two pre-existing `pause_run_*` / `unpause_run_sets_pending_control` failures verified to exist before this cleanup (confirmed via `git stash`).\n\n**Findings I deliberately skipped** (not high-impact enough or would require API surface changes outside this cleanup):\n- Splitting `WorkerControlBusError` into publish/subscribe error types\n- Replacing `BoxFuture` with `async_trait` (style consistency)\n- Moving WS-URL construction onto `ServerTarget` (touches `fabro-client`, `fabro-sandbox`)\n- Adopting `fabro_util::backoff::BackoffPolicy` (small benefit; existing hand-rolled is correct)\n- Collapsing `WorkerControlSocket` enum into `Box` (works but tungstenite's `from_raw_socket` generic constraints make this fiddly)\n- Per-run inner mutex sharding in the bus (premature for local single-node)\n- `cleanup_worker_control_bus_for_run` spawn-per-call (sync-fast-path optimization; correctness fine)" }, "node_outcomes": { - "preflight_compile": { - "status": "succeeded", - "context_updates": { - "command.output": "blob://sha256/12ae32cb1ec02d01eda3581b127c1fee3b0dc53572ed6baf239721a03d82e126" - }, - "notes": "Script completed: cargo check -q --workspace 2>&1", - "usage": null, - "timing": { - "wall_time_ms": 0, - "inference_time_ms": 0, - "tool_time_ms": 130559, - "active_time_ms": 130559 - } - }, - "preflight_lint": { - "status": "succeeded", - "context_updates": { - "command.output": "blob://sha256/12ae32cb1ec02d01eda3581b127c1fee3b0dc53572ed6baf239721a03d82e126" - }, - "notes": "Script completed: cargo +nightly-2026-04-14 clippy -q --workspace --all-targets -- -D warnings 2>&1", - "usage": null, - "timing": { - "wall_time_ms": 0, - "inference_time_ms": 0, - "tool_time_ms": 143452, - "active_time_ms": 143452 - } - }, - "fixup": { - "status": "succeeded", - "context_updates": { - "last_stage": "fixup", - "last_response": "All verify steps pass.

After the control-bus refactor, pause/unpause now require a `RunAnswerTransport` on the managed run, so the handler returned 409 \"Run worker is not available.\"\n\n**Fix:** In both tests, attach a worker `RunAnswerTransport` (built via the existing `worker_transport_with_receiver` helper) to the managed run alongside the manual status/pid mutation.\n\nVerified:\n- `cargo +nightly-2026-04-14 fmt --check --all`\n- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings`\n- `cargo nextest run --workspace --profile ci` (6438 passed, 179 skipped)\n- `cargo dev docs check`\n- `bun install`, `apps/fabro-web` typecheck + test, `lib/packages/fabro-api-client` typecheck\n- `cargo dev build -- -p fabro-cli --release`" + }, + "notes": "Stage completed: fixup", + "usage": { + "input": { + "usage": { + "model": { + "provider": "anthropic", + "model_id": "claude-opus-4-7" + }, + "tokens": { + "input_tokens": 47401, + "output_tokens": 8522, + "reasoning_tokens": 0, + "cache_read_tokens": 1165952, + "cache_write_tokens": 193869 + } + }, + "facts": { + "algorithm": "anthropic", + "cache_write_5m_tokens": 193869, + "cache_write_1h_tokens": 0 + } + }, + "total_usd_micros": 2244712 + }, + "files_touched": [ + "/home/daytona/workspace/fabro/lib/crates/fabro-server/src/server/tests.rs" + ], + "timing": { + "wall_time_ms": 0, + "inference_time_ms": 140463, + "tool_time_ms": 518224, + "active_time_ms": 658687 + } + }, "implement": { "status": "succeeded", "context_updates": { @@ -2177,55 +2195,23 @@ "active_time_ms": 4319397 } }, - "toolchain": { + "preflight_lint": { "status": "succeeded", "context_updates": { - "command.output": "blob://sha256/fc14b2ba2d770e5cd3169df7a29525c962adfc4cfa3097b9098c63ebd61a748c" + "command.output": "blob://sha256/12ae32cb1ec02d01eda3581b127c1fee3b0dc53572ed6baf239721a03d82e126" }, - "notes": "Script completed: 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/;
