    "graph.goal": "# Focused `Blocked` Run Status Plan\n\n## Summary\n\n- Add `Blocked` as a first-class run lifecycle status for runs that are waiting on external intervention.\n- Keep `Paused` separate. `Paused` is operator intent; `Blocked` is an execution condition.\n- Keep existing engine concepts in scope: `Succeeded` and `Dead` remain real statuses in this pass.\n- Make `/api/v1/runs`, `/api/v1/runs/{id}`, mutation responses, and `/api/v1/runs/{id}/state` use one truthful operator vocabulary.\n- Keep `/api/v1/boards/runs` explicitly lossy and web-optimized.\n- Add `BlockedReason`, starting with `human_input_required`.\n- Add explicit lifecycle events for `run.queued`, `run.blocked`, and `run.unblocked`.\n- No alerting/email work in this pass.\n\n## Scope And Decisions\n\n### Canonical Operator Status Vocabulary\n\nUse one shared run status vocabulary across the durable projection, operator APIs, generated clients, and CLI:\n\n- `submitted`\n- `queued`\n- `starting`\n- `running`\n- `blocked`\n- `paused`\n- `removing`\n- `succeeded`\n- `failed`\n- `dead`\n\nAdditional decisions:\n\n- `cancelled` remains `failed` plus `status_reason=cancelled`; it is not a new top-level run status in this pass.\n- `status` becomes required/non-null on operator-facing surfaces.\n- If a run exists but the projection has no lifecycle status yet, synthesize `submitted` rather than returning `null`.\n- `/api/v1/boards/runs` remains a derived UI projection and does not need to preserve the full operator vocabulary.\n- This is an accepted breaking contract change. The app is greenfield with no prod installs, so do not add versioning, migration work, serde aliases, or compatibility shims for the status-enum changes or `reason -> status_reason` rename.\n\n### `Blocked` Semantics\n\n- `Blocked` means the run cannot proceed until some external condition is resolved.\n- In this pass the only `BlockedReason` is `human_input_required`, but the enum and event shapes should allow more reasons later.\n- `blocked_reason` is a separate field everywhere; do not overload `status_reason`.\n- A paused run may still retain `blocked_reason` if the underlying block is unresolved.\n- `Paused` wins as the visible status while a run is paused.\n- If a blocked run is unpaused and the block is still unresolved, the visible state returns to `blocked` (via the `paused -> running -> blocked` event sequence in Section 2).\n- If the block resolves while the run is paused, clear `blocked_reason` and emit `run.unblocked`, but leave `status=paused`.\n\n### Board Contract\n\n`/api/v1/boards/runs` remains a Trello-style projection for the web UI only.\n\nBoard columns after this change:\n\n- `initializing`\n- `running`\n- `blocked`\n- `succeeded`\n- `failed`\n\nBoard mapping rules:\n\n- `submitted`, `queued`, `starting` -> `initializing`\n- `running`, `paused` -> `running`\n- `blocked` -> `blocked`\n- `succeeded` -> `succeeded`\n- `failed`, `dead` -> `failed`\n- `removing` -> off-board\n\nAdditional board decisions:\n\n- Replace the current `waiting` column with `blocked`.\n- Replace the older `working | review | merge` board schema entirely. Update OpenAPI `BoardColumn`, server responses, and web `ColumnStatus` types to use only `initializing | running | blocked | succeeded | failed`.\n- Keep failed behavior as-is.\n- Keep paused runs visually indistinguishable from running in this pass.\n- Blocked cards should show the oldest unresolved pending interview question text.\n- That question text should be derived only in `/api/v1/boards/runs`, not added to `StoreRunSummary`.\n- Known limitation for this pass: a run that is both paused and still blocked appears in the `running` column. A follow-up can add a paused attention indicator or richer board card state.\n\n## Implementation Units\n\n### 1. Shared Types And OpenAPI\n\nUpdate the shared contract in:\n\n- [docs/api-reference/fabro-api.yaml](/Users/bhelmkamp/p/fabro-sh/fabro/docs/api-reference/fabro-api.yaml)\n- [lib/crates/fabro-types/src/status.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-types/src/status.rs)\n- [lib/crates/fabro-types/src/run_event/mod.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-types/src/run_event/mod.rs)\n- generated Rust client/types under `lib/crates/fabro-api`\n- generated TypeScript models under `lib/packages/fabro-api-client/src/models/`\n\nRequired changes:\n\n- Collapse OpenAPI `RunStatus` and `InternalRunStatus` into one shared `RunStatus` schema with the canonical operator vocabulary above.\n- Add `Queued` and `Blocked` variants to the Rust `RunStatus` enum in `status.rs`. Update `is_active()` to include both (they are incomplete active states). Update `is_terminal()`, `can_transition_to()`, `Display`, and `FromStr` accordingly.\n- This is an intentional breaking API change: remove public `completed` and `cancelled`, add public `blocked`, `removing`, `succeeded`, and `dead`, and rename `RunStatusRecord.reason` to `status_reason` with no compatibility layer.\n- Add `BlockedReason` schema with initial value `human_input_required`.\n- Add `blocked_reason` to:\n  - `RunStatusResponse`\n  - `RunStatusRecord`\n  - `StoreRunSummary`\n- Rename `RunStatusRecord.reason` to `status_reason` and keep `blocked_reason` separate.\n- Make `StoreRunSummary.status` a non-null `RunStatus` reference instead of `string | null`.\n- Keep `status_reason` on responses and summaries.\n- Expose `pending_interviews` on the `RunProjection` schema for `/api/v1/runs/{id}/state`.\n- Regenerate Rust and TypeScript API clients after the spec update.\n\n### 2. Lifecycle Events And Transition Rules\n\nAdd event-backed lifecycle support in:\n\n- [lib/crates/fabro-workflow/src/event.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-workflow/src/event.rs)\n- [lib/crates/fabro-types/src/run_event/mod.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-types/src/run_event/mod.rs)\n- [lib/crates/fabro-workflow/src/handler/human.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-workflow/src/handler/human.rs)\n- [lib/crates/fabro-workflow/src/operations/start.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-workflow/src/operations/start.rs)\n- [lib/crates/fabro-workflow/src/run_control.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-workflow/src/run_control.rs)\n- [lib/crates/fabro-types/src/status.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-types/src/status.rs)\n\nAdd new explicit lifecycle events:\n\n- `run.queued`\n- `run.blocked`\n- `run.unblocked`\n\nPayload decisions:\n\n- `run.blocked` carries `blocked_reason`.\n- `run.unblocked` is a minimal effect event; it does not repeat `blocked_reason`.\n- `run.queued` mirrors existing status-transition event style.\n\nEvent ordering and rules:\n\n- Emit `run.queued` from the server `start`/`resume` path at the moment the run is inserted into managed queued state. Persist it to the durable run event log there; do not synthesize `queued` later in projection replay.\n- Emit `run.started` later, when execution begins.\n- Keep `run.starting` and `run.running` as the worker bootstrap/execution transitions.\n- `run.blocked` and `run.unblocked` must be durable `run.*` events appended through the normal workflow event sink, not SSE-only notifications and not projection-synthesized state.\n- Add a run-scoped blocked-state tracker in the workflow runtime, owned by `StartServices`/`RunSession` in `operations/start.rs` and passed into `HumanHandler` through a new `EngineServices` field such as `blocked_state_tracker: Option<Arc<BlockedStateTracker>>`. The tracker should guard unresolved interview count with a mutex so parallel human stages can safely detect `0 -> 1` and `1 -> 0` transitions.\n- On first pending interview (`0 -> 1` unresolved questions), the workflow runtime emits `interview.started` and then appends `run.blocked`.\n- While already blocked, additional `interview.started` events do not emit another `run.blocked`.\n- On final interview resolution (`1 -> 0` unresolved questions), the workflow runtime emits `interview.completed` or `interview.timeout` or `interview.interrupted` and then appends `run.unblocked`.\n- Do not emit `run.unblocked` when a blocked run reaches `failed`, `succeeded`, or `dead`; terminal events end the blocked condition implicitly.\n\nPause/unpause decisions:\n\n- Keep existing cooperative pause behavior for actively running work.\n- In this pass, make pause immediate only when the current visible status is `blocked`.\n- For immediate pause from blocked:\n  - append `run.pause.requested`\n  - append `run.paused` immediately\n  - do not emit `run.unblocked`\n  - this direct server-appended `run.paused` may race with worker-emitted interview resolution and `run.unblocked`; accept that race in this pass and make projection logic order-insensitive so either ordering converges on the same final paused-or-unblocked state\n- For unpause when the underlying human block is still unresolved:\n  - append `run.unpause.requested`\n  - append `run.unpaused`\n  - append `run.blocked`\n  - this is explicitly `paused -> running -> blocked`; do not add a direct `paused -> blocked` transition\n- For unpause when the underlying block has already resolved:\n  - append `run.unpause.requested`\n  - append `run.unpaused`\n- If the blocked condition resolves while paused:\n  - emit the interview resolution event\n  - emit `run.unblocked`\n  - keep `status=paused`\n\nTransition helper updates in `status.rs`:\n\n- add `submitted -> queued`\n- add `queued -> starting`\n- add `running -> blocked`\n- add `blocked -> running`\n- add `blocked -> paused` (immediate pause from blocked)\n- preserve `running -> paused`\n- preserve `paused -> running`\n- preserve non-terminal `-> failed` (including from `blocked`)\n- keep `dead` as a real terminal status in this pass\n\n### 3. Durable Projection And Truthful Run APIs\n\nUpdate durable state and operator-facing API behavior in:\n\n- [lib/crates/fabro-store/src/run_state.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-store/src/run_state.rs)\n- [lib/crates/fabro-store/src/types.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-store/src/types.rs)\n- [lib/crates/fabro-store/src/slate/mod.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-store/src/slate/mod.rs)\n- [lib/crates/fabro-server/src/server.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-server/src/server.rs)\n- [lib/crates/fabro-server/src/demo/mod.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-server/src/demo/mod.rs)\n\nProjection changes:\n\n- Extend `RunStatusRecord` and `StoreRunSummary` (Rust: `RunSummary`) with `blocked_reason`.\n- Store `blocked_reason=human_input_required` while blocked on pending human input.\n- Preserve `blocked_reason` while the run is paused over an unresolved block.\n- Clear `blocked_reason` on `run.unblocked`.\n- Clear pending interviews on terminal completion/failure as today.\n- Synthesize `submitted` if a run exists but no lifecycle status has been projected yet.\n\nOperator API changes:\n\n- `/api/v1/runs` and `/api/v1/runs/{id}` become truthful operator surfaces.\n- Remove the lossy status remap that currently converts:\n  - `removing -> running`\n  - `succeeded -> completed`\n  - `failed(cancelled) -> cancelled`\n  - `dead -> failed`\n- Expose the canonical operator vocabulary directly on these endpoints.\n- Keep `status_reason=cancelled` on failed cancellations.\n- Include `blocked_reason` alongside `status_reason` and `pending_control`.\n- Because `ManagedRun.status` uses the generated API `RunStatus`, this enum collapse intentionally requires broad match-arm updates throughout `lib/crates/fabro-server/src/server.rs`, `lib/crates/fabro-server/src/demo/mod.rs`, and generated client consumers.\n- Return the actual current status from mutation endpoints rather than a target status:\n  - `start` returns `queued`\n  - `pause` from `blocked` returns `paused`\n  - `unpause` back to unresolved human input returns `blocked`\n  - cooperative `pause` from `running` still returns `running` with `pending_control=pause` until the worker reaches a pause point\n\nRaw state endpoint changes:\n\n- `/api/v1/runs/{id}/state` remains the raw projection surface.\n- Make the schema truthful to the Rust payload by exposing `pending_interviews`.\n- Use `RunStatusRecord.status_reason` plus `blocked_reason` there too.\n\nLive managed-run reconciliation:\n\n- Update `update_live_run_from_event()` in `server.rs` for `run.queued`, `run.blocked`, and `run.unblocked`.\n- Keep `Blocked` treated as an incomplete active state for shutdown/startup handling in this pass.\n- Allow blocked runs to be cancelled through the existing cancel endpoint.\n- Update `pause_run` to accept `Blocked` in addition to `Running`, implementing the immediate-pause path (appending `run.paused` directly rather than sending a control signal to the worker).\n- Update `should_reconcile_run_on_startup` to include `Blocked` and `Queued`.\n\n### 4. Web Board Projection And UI\n\nUpdate the web-only board projection in:\n\n- [lib/crates/fabro-server/src/server.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-server/src/server.rs)\n- [apps/fabro-web/app/data/runs.ts](/Users/bhelmkamp/p/fabro-sh/fabro/apps/fabro-web/app/data/runs.ts)\n- [apps/fabro-web/app/routes/runs.tsx](/Users/bhelmkamp/p/fabro-sh/fabro/apps/fabro-web/app/routes/runs.tsx)\n- [apps/fabro-web/app/routes/run-detail.tsx](/Users/bhelmkamp/p/fabro-sh/fabro/apps/fabro-web/app/routes/run-detail.tsx)\n\nRequired changes:\n\n- Replace `waiting` with `blocked` in the board projection and UI types.\n- Add `queued` and `blocked` to the `RunStatus` type and `runStatusDisplay` record in `apps/fabro-web/app/data/runs.ts` with appropriate labels and colors.\n- Update OpenAPI `BoardColumn`, server board responses, and web `ColumnStatus` types to remove `working`, `review`, and `merge`.\n- Keep board columns `initializing | running | blocked | succeeded | failed`.\n- Map statuses per the board contract above.\n- Keep `removing` off-board.\n- Keep `paused` in the `running` column with no special indicator in this pass.\n- Keep `dead` in the `failed` column on the board.\n- Populate board card question text from the oldest unresolved pending interview only in `/api/v1/boards/runs`.\n- Implement that by having `list_board_runs` open run readers only for summaries whose mapped board column is `blocked`, inspect `RunProjection.pending_interviews`, and choose the oldest question by earliest `started_at`. Keep `StoreRunSummary` unchanged. This may replay or reload projection state per blocked run during board refresh; that performance profile is acceptable in this pass, and implementers should reuse existing `run_store.state()` / projection-cache behavior where available rather than introducing a new caching layer.\n- Do not add question text to `StoreRunSummary`.\n\nBoard refresh behavior:\n\n- Preserve the current status-refresh triggers and add the new ones. `STATUS_EVENTS` in `apps/fabro-web/app/routes/runs.tsx` should include:\n  - `run.submitted`\n  - `run.queued`\n  - `run.starting`\n  - `run.running`\n  - `run.removing`\n  - `run.paused`\n  - `run.unpaused`\n  - `run.blocked`\n  - `run.unblocked`\n  - `run.completed`\n  - `run.failed`\n  - `interview.started`\n  - `interview.completed`\n  - `interview.timeout`\n  - `interview.interrupted`\n\nRationale:\n\n- `run.blocked` and `run.unblocked` cover status changes.\n- `interview.*` still need to refresh the board because the displayed oldest unresolved question can change while the run remains blocked.\n\n### 5. CLI Consumers\n\nUpdate CLI consumers in:\n\n- [lib/crates/fabro-cli/src/server_runs.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-cli/src/server_runs.rs)\n- [lib/crates/fabro-cli/src/commands/runs/list.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-cli/src/commands/runs/list.rs)\n- [lib/crates/fabro-cli/src/commands/run/wait.rs](/Users/bhelmkamp/p/fabro-sh/fabro/lib/crates/fabro-cli/src/commands/run/wait.rs)\n\nRequired changes:\n\n- Treat `/api/v1/runs` as truthful and stop inventing fallback status in `server_runs.rs`.\n- Add display/color handling for `Queued` and `Blocked`.\n- Keep `Succeeded` as the success exit state for CLI wait behavior in this pass.\n- Keep `Dead` as a real displayable terminal state when it is actually present.\n- Stop using `Dead` as a synthetic fallback for missing server summary status now that `status` is non-null.\n- Continue to show `status_reason=cancelled` for cancellations rather than inventing a `Cancelled` top-level status.\n\n## Test Plan\n\n### Shared Types And Event Model\n\n- `lib/crates/fabro-types/src/run_event/mod.rs`\n  - round-trip serialization for `run.queued`, `run.blocked`, and `run.unblocked`\n  - `run.blocked` payload includes `blocked_reason`\n- `lib/crates/fabro-types/src/status.rs`\n  - transition tests for `submitted -> queued`, `running -> blocked`, and `blocked -> running`\n  - paused overlay path still flows through explicit event order rather than a direct `paused -> blocked` transition\n- `lib/crates/fabro-workflow/src/handler/human.rs`\n  - first pending interview emits `interview.started` then durable `run.blocked`\n  - second pending interview while already blocked does not emit another `run.blocked`\n  - final resolution emits `interview.completed`/`timeout`/`interrupted` then durable `run.unblocked`\n- `lib/crates/fabro-workflow/src/operations/start.rs`\n  - run-scoped blocked-state tracker emits exactly one `run.blocked` on `0 -> 1` and exactly one `run.unblocked` on `1 -> 0`, including parallel human-stage races\n\n### Durable Projection And Server\n\n- `lib/crates/fabro-store/src/run_state.rs`\n  - `run.queued` sets `status=Queued`\n  - `run.blocked` sets `status=Blocked` and `blocked_reason=HumanInputRequired`\n  - `run.unblocked` while status is `Blocked` clears `blocked_reason` and restores `Running`\n  - paused-over-blocked preserves `blocked_reason` while `status=Paused`\n  - unpause-to-still-blocked yields `RunUnpaused` followed by `RunBlocked`\n  - interview resolution while paused clears `blocked_reason` without changing visible `Paused`\n  - missing lifecycle status synthesizes `Submitted`\n- `lib/crates/fabro-store/src/slate/mod.rs`\n  - list/find summaries expose non-null `status`\n  - summaries expose `blocked_reason`\n- `lib/crates/fabro-server/src/server.rs`\n  - `/api/v1/runs` and `/api/v1/runs/{id}` expose `blocked`, `removing`, `succeeded`, and `dead` directly\n  - mutation responses return actual current status\n  - blocked runs are cancellable\n  - startup/shutdown handling still treats blocked runs as incomplete active work in this pass\n  - `/api/v1/runs/{id}/state` includes `pending_interviews`\n  - `start`/`resume` append durable `run.queued` when enqueueing\n  - board response emits `blocked` column, blocked question text, paused-in-running, removing off-board, and dead-in-failed\n\n### Web UI\n\n- `apps/fabro-web/app/data/runs.test.ts`\n  - accepts `blocked`, `queued`, `removing`, `succeeded`, and `dead`\n  - removes dependency on `waiting`\n- `apps/fabro-web/app/routes/runs.test.tsx`\n  - blocked runs render in the `blocked` lane\n  - paused runs remain in the `running` lane\n  - blocked card shows oldest unresolved question text\n  - `STATUS_EVENTS` retains `run.starting` and `run.running` while adding the new blocked/queued events\n  - question text refreshes correctly on `interview.*` events without a status change\n\n### CLI\n\n- `lib/crates/fabro-cli/src/commands/runs/list.rs`\n  - `Queued` and `Blocked` render with expected labels/colors\n  - `Dead` remains renderable when actually returned by the API\n- `lib/crates/fabro-cli/src/commands/run/wait.rs`\n  - `Succeeded` remains the success exit state\n  - `Blocked` is non-terminal and continues waiting\n  - no synthetic `Dead` fallback is used for server summary status\n\n## Explicit Non-Goals\n\n- No alerting, email, or notification policy in this pass.\n- No new paused indicator on the board in this pass.\n- No broader redesign of cooperative pause for actively running work.\n- No change to cancellation semantics beyond making blocked runs cancellable and keeping `failed + status_reason=cancelled`.\n- No attempt to make blocked runs survive restart as a durable parked state in this pass.\n",
