# ThothII workflow UI contracts
|
|
|
|
- Pi reasoning arrives as nested `message_update.assistantMessageEvent.type = thinking_delta`.
|
|
The backend maps it to the named SSE event `activity_delta`; the frontend EventSource must
|
|
explicitly subscribe to that name. Model activity is separate from final `text_delta` output.
|
|
- Session create/resume must preserve the configured or persisted thinking level. Forcing
|
|
`thinking: off` disables the upstream signal and makes the activity panel legitimately empty.
|
|
- A join-only `reviewer_decide` proposal is one complete, atomic join set. The read-only
|
|
`join-review` widget persists every proposed join on Continue; `Other — specify` persists none
|
|
and requires the model to propose the complete corrected set again. Ledger read, sequence
|
|
assignment, and atomic replacement share a per-session cross-process writer lock.
|
|
- A v2 phase summary accepts `open_questions?: string[]`. Validate this at the gate boundary and
|
|
normalize legacy malformed entries defensively in the viewer so one object cannot crash React.
|
|
- `SqlViewer`'s horizontal/vertical layout control is meaningful only with multiple SQL blocks;
|
|
hide it for the single CTE result shown by `CteResultViewer`.
|
|
- A Pi turn is `idle`, `running`, `waiting`, or `failed`. A reviewer gate/request moves it to
|
|
`waiting`; the reviewer response and steering move it back to `running`; provider failures and
|
|
unexpected Pi child exits mark it `failed` without forwarding raw failure detail.
|
|
- Resume preserves `running`/`waiting` runtimes. After manifest/readiness validation, every cold
|
|
path clears old SSE buffer/subscribers before reopen—including when a crashed child has already
|
|
left no runtime—and reuses persisted provider/model/thinking. Failed validation does not clear.
|
|
- A successful Resume of the already selected session increments the stream generation so React
|
|
closes the old EventSource and opens the same session URL again. Failed Resume must not reconnect.
|
|
- SSE endpoints are intentionally keep-alive. Browser cleanup and one-off probes must explicitly
|
|
close the EventSource or cancel/abort the response reader after their terminal event.
