 When SubWorker-management tools are available, create direct children with `SubWorkerSpawn`, discover them with `WorkerList`, continue them with `WorkerSendInput`, and release their delegated authority with `WorkerStop`. Pass the exact `{ kind: "sub_worker", name }` subject returned by `WorkerList`; do not invent direct-only aliases. SubWorker notifications are background signals for the parent Worker to handle at a natural stopping point. Do not ignore routine follow-up, but do not interrupt the current user request unnecessarily.
 
-For Runtime Workers, `WorkerSendInput` submits user input: Idle Workers can start a fresh turn, while Running or Paused Workers durably queue it for a later turn. Queueing does not implicitly resume a paused run; Cancel/error retains pending input until explicitly continued. Direct SubWorkers still require Idle for `WorkerSendInput`. When `WorkerNotify` is available and information should be incorporated into work already in progress, use `WorkerNotify` instead; notifications are advisory and do not create a queued Submit.
+`WorkerSendInput` requires an Idle Worker and never queues input. Non-Idle Workers reject it; when information should be incorporated into work already in progress, use `WorkerNotify` instead. Notifications are advisory and do not create a queued Submit. Direct SubWorkers also require Idle for `WorkerSendInput`; do not send follow-up input until they are Idle. The Submit queue is for human-controlled Web/TUI interaction, not Orchestrator scheduling. Do not retry SendInput in a polling loop or cancel/pause work to bypass this restriction.
 
 The parent Worker does not need to keep a turn open or call tools solely to wait for a notification. Do not use `sleep` or polling loops just to wait for SubWorker output; if there is no useful immediate work, return control and handle the SubWorker when notified or when the user next asks.

+## Workspace Home fixture
+
+`scenarios/workspace-home.json` captures the production work dashboard with owner, non-owner,
+long-name, empty, and intentionally failing-review Workspace projections at 1440px, 768px, and 390px.
+The partial-error route deliberately returns HTTP 503 only for Merge Requests; captures should retain
+that request/console/visible error while showing successful active-work and recent-update feeds.
+It uses no real account or private Workspace data. Build `web/workspace` first, then run from `tools/web-ux`:
+
+```sh
+deno task web-ux capture --scenario scenarios/workspace-home.json --output ../../target/web-ux --run-id home-review
+```
+
+The scenario owns a fixture server on localhost port 15281 and stops only that server. The production
+Home browser regression (`browser-tests/workspace_home_shell_test.ts`, included in `test:browser`)
+also checks 320px, both themes, keyboard record navigation, bounded loading, independent slow/error
+feeds, explicit refresh, and absence of Host requests.
+
+## Workspace Identity settings fixture
+
+`scenarios/workspace-settings.json` uses the same owned fixture server with synthetic metadata,
+public identity, and deletion-preflight responses. It covers owner, member, long name, pending
+provisioning, and intentional signing-identity HTTP503 states at 1440px, 768px, and 390px.
+Build `web/workspace` before capture. No real keys, accounts, or deletion requests are used.
+`browser-tests/workspace_settings_shell_test.ts` also checks 320px and both themes, Edit/Save/Cancel,
+keyboard disclosure/focus return, full public bundle access, scoped errors, and exact-name deletion
+confirmation. Interaction screenshots are saved under `target/web-ux/settings-interactions`.
+
+## Console pending input fixture
+
+`scenarios/console-pending.json` uses the owned Console history fixture with `?pending=both`,
+`queue`, `notifications`, `legacy`, or `empty`. Each state includes a task for typography comparison.
+It captures 1440px, 768px, and 390px; `browser-tests/console_pending_shell_test.ts` additionally checks
+320px and both themes, independent group visibility, full-width single groups, uniform 16px rows,
+monospace inheritance, truncation, and retained-session cancellation gating. Live revision-fenced
+cancellation and state transitions are covered by Console component tests. No real Worker is used.
+
