## Summary
Settings > Integrations now reflects the server's actual integration
readiness instead of only static `settings.toml` booleans. This adds
`/api/v1/system/integrations` as the runtime source of truth, covering
server config, vault credential presence, and Slack Socket Mode
connection state.
## What Changed
- Added shared `fabro-types` integration status models and reused them
from `fabro-api` to avoid duplicate API/domain types.
- Added `GET /api/v1/system/integrations` to the OpenAPI spec, Rust
server routes, demo routes, and generated TypeScript client.
- Reports GitHub and Slack status as `disabled`, `missing_credentials`,
`configured`, `connecting`, `connected`, or `error`, with non-secret
metadata and missing credential names.
- Tracks Slack Socket Mode runtime state from the Slack connection loop
and respects explicit `server.integrations.slack.enabled = false` even
when vault tokens exist.
- Updated the Integrations settings page to read the new runtime
endpoint, so a vault-configured Slack setup no longer appears simply as
disabled.

## Summary
Removes the standalone `agent.context_window.snapshot` event and instead
attaches the context-window projection directly to `agent.message`. This
eliminates the async provider token-count API calls that the old
approach required, and simplifies the event log to a single event type
carrying all post-response agent data.
## What Changed and Why
**Before:** After each LLM turn, the agent emitted a separate
`agent.context_window.snapshot` event — first a local estimate, then
potentially a second one after an async `count_input_tokens` call
resolved (or after response usage arrived). This required fingerprint
deduplication state, a `close_token` to cancel in-flight counts, and
frontend handling for the extra event type.
**After:** The `AgentEvent::AssistantMessage` variant carries an
`Option<StageContextWindowProjection>`. The projection is computed
locally at request-build time and then refined using response token
usage when available (`ResponseUsageScaledBreakdown`), or kept as a
`LocalEstimate` when response usage is absent. No provider API calls are
made.
### Plan Summary
- **Task 1:** Added `context_window:
Option<StageContextWindowProjection>` to `AgentMessageProps` (Rust types
+ OpenAPI), removed `AgentContextWindowSnapshotProps` and
`EventBody::AgentContextWindowSnapshot`.
- **Task 2:** Removed the spawned `count_input_tokens` task,
`close_token`, fingerprint sets, and both snapshot-emit methods from
`Session`. Added `context_window_from_response_usage` to
`context_window.rs`; `BuiltRequest` now holds the local projection
instead of the tool list.
- **Task 3:** Workflow conversion copies `context_window` from
`AgentEvent::AssistantMessage` into `AgentMessageProps`; store reducer
reads it from `AgentMessage` instead of the removed snapshot variant and
stamps `event_seq`.
- **Task 4:** GET endpoint tests updated to seed data via
`agent.message` with embedded context-window; endpoint behavior
unchanged.
- **Task 5:** Frontend constant and tests for
`agent.context_window.snapshot` removed; `agent.message` already
invalidates `stageContextWindow` through existing stage-activity
handling. TypeScript client regenerated with the new `AgentMessageProps`
model.
### Key Design Decisions
- **No provider token-count API calls** during normal execution —
context-window accuracy relies on local estimates scaled by response
usage, which is always available for successful turns.
- **Failed-before-response turns** emit no context-window data
(`context_window: None`), matching the old behavior where a snapshot
would have been emitted but response-usage scaling would never arrive.
- `BuiltRequest` drops the `tools` field (only needed for the
now-removed snapshot emission path); the local projection is computed at
build time and stored directly.

Adds /runs/:id/sandbox between Files Changed and Terminal, gated by
the same sandbox-presence check as Terminal. The route fetches
SandboxDetails through a new useRunSandboxDetails SWR hook and renders
provider-neutral panels for Overview, Resources, Labels, and
Timestamps. Null fields render as muted em dashes.
Add committed, uncommitted, and all scope handling for run files with source reporting for sandbox and final patch responses.
Wire the run files page to persist scope in the URL and cache each scope independently.
Persist resolved run titles on creation, expose title update events, and add the run title PATCH API. Regenerate API clients and refresh web/server invalidation so title changes are reflected across run detail and board views.
Expand the OpenAPI contract for frontend auth and workflow routes, regenerate the TypeScript Axios client, and route web API calls through generated client classes while preserving SSE and install exceptions.
Route command stderr into stdout at execution time and expose a single output log across events, projections, API clients, and the web UI. Keep replay compatibility for older command.completed events that still contain split stdout/stderr fields.
### Summary
Billing and stage lists now use the event-sourced `RunProjection` as
their source of truth, so running and retrying stages appear immediately
and runtimes keep advancing in the UI. This removes the checkpoint
completed-node bypass that hid in-flight work and froze totals until the
next server response.
### Plan Summary
- Store stage `started_at`, terminal `duration_ms`, server-internal
`usage`, and lifecycle `state` on `StageProjection`.
- Populate those fields from stage lifecycle events, including retry
transitions and per-attempt reset on new starts.
- Render `/runs/{id}/stages` and `/runs/{id}/billing` from
`RunProjection.iter_stages()`.
- Expose the new API/client fields and tick in-flight billing runtimes
on the web UI.

Projection --> StagesAPI["GET /runs/{id}/stages"]
Projection --> BillingAPI["GET /runs/{id}/billing"]
StagesAPI --> StageUI["Stage sidebar/stages view"]
BillingAPI --> BillingUI["Billing tab live totals"]
```
### Key decisions
Retry and revisit handling stays one row per node id: latest visit data
wins, while first-seen event sequence keeps ordering stable with
finalize output. `state` is stored rather than derived so `Retrying` is
representable, and old serialized projections still work through the
`effective_state()` fallback. Billing `usage` remains server-internal
and is skipped on the wire; public schemas only expose the fields needed
by `/stages`, `/billing`, and the frontend live timer.
Added focused reducer, server retry/revisit, API round-trip, billing UI,
and event invalidation coverage.

## Summary
Stage detail now loads activity from a canonical stage-scoped events
endpoint instead of falling back to the first 1000 run-wide events. This
fixes empty panes for late stages in long runs and removes the
presentation-shaped `StageTurn` API from the wire.
### Plan Summary
- Add `GET /runs/{id}/stages/{stageId}/events` with cursor pagination
and server-side `node_id` filtering.
- Replace frontend stage-turn/fallback loading with paginated
stage-events loading and local event-to-activity projection.
- Broaden SSE/SWR invalidation so every activity event consumed by the
reducer refreshes the per-stage cache.
- Remove `StageTurn` schemas/client models and update demo fixtures plus
pagination/handler/reducer tests.
## What changed and why
The store now scans the run event prefix and filters by `node_id` before
applying the `limit + 1` cutoff. That preserves sparse late-stage
matches that would otherwise be dropped if we reused the run-wide
limited scan and filtered afterward. The real-mode handler returns an
empty page for an unknown stage id in an existing run, while preserving
404 for missing runs.
On the frontend, `run-stages` fetches all pages for the selected stage
and feeds them through `eventsToActivity`, keeping `TurnType` as a local
presentation model. Invalidation now targets `runs.stageEvents(runId,
stageId)` for lifecycle and reducer-consumed activity events
(`stage.prompt`, agent messages/tools, and command events), so active
panes refresh from the existing run event subscription.
The OpenAPI document and generated TS client now expose
`listStageEvents` and drop stale `StageTurn` models. Demo mode serves a
`detect-drift` stage-events fixture using the same cursor semantics as
the real endpoint.
## API notes
`/runs/{id}/stages/{stageId}/turns` is removed; clients should use
`/runs/{id}/stages/{stageId}/events?since_seq=&limit=` and project
events locally. The `stageId` path segment for this endpoint is the
workflow node id, not the visit-qualified `node_id@visit` form used by
command logs/artifacts.

Persist command stdout/stderr through scratch logs and finalized CAS refs, expose byte-offset tailing through the API, and render separate streaming panels in the web run view.
Resolve command output blob refs for execution-time consumers such as edge routing and retros, and make Docker streaming timeout/cancel drain output before returning.
Replace React Router loader/action state paths with SWR query and mutation hooks.
Add targeted run and board EventSource managers that invalidate SWR keys, and refresh embedded SPA assets.
