Pull request overview

Adds a richer “Session Detail” modal to the Ink TUI Agents screen, enabling drill-down into a selected session with a turn timeline, recent diff context, and live output/steering controls.

Changes:

Implement SessionDetail modal UI with metadata, turn timeline (scrollable), diff preview, and a right-side log panel when wide enough.
Add steering input flow and periodic session detail polling while the modal is open.
Extend TUI rendering tests and fixtures to cover modal open/close, steering, timeline scrolling, and log streaming.

tests/tui/screens.test.mjs	Adds integration-style Ink render tests for the new modal behaviors and streaming updates.
tests/tui/fixtures.mjs	Expands fixtures with turns, metadata fields, and a longer diff payload for modal rendering scenarios.

+    if (!wsBridge || typeof wsBridge.on !== "function") return undefined;
+    const off = wsBridge.on("logs:stream", (payload) => {
+      const payloadSessionId = String(payload?.sessionId || payload?.id || payload?.session?.id || "");
+      if (!detailView?.session?.id || payloadSessionId !== String(detailView.session.id)) return;
+      const line = streamPayloadToLogLine(payload);
+      if (!line) return;
+      setLogLines((current) => [...current.slice(-(MAX_LOG_LINES - 1)), line]);
+    });


The logs:stream handler filters on payload.sessionId/payload.id, but the canonical TUI logs:stream payload contract does not include any session identifier (it is {logType, query, filePath, line, raw, level, timestamp} with additionalProperties: false). In production this will likely drop all streamed log lines while the detail modal is open. Consider either (a) not filtering by session at all, (b) filtering using payload.query / payload.filePath in a way that matches how logs are subscribed, or (c) extending the event contract + emitter to include a sessionId field and updating the schema accordingly.

The screen no longer has a periodic tick to keep clockMs advancing and to re-run reconcileSessionEntries(...) when the upstream sessions prop is unchanged. This will cause age/idle counters (and any retention logic in reconcileSessionEntries) to freeze until a sessions update arrives. Reintroduce a setInterval (e.g. 1s) that updates clockMs and recomputes entries from liveSessionsRef.current (and make sure it’s cleaned up on unmount).

Suggested change

React.useEffect(() => {

const intervalId = setInterval(() => {

const now = Date.now();

setClockMs(now);

setEntries((previous) => {

const nextEntries = reconcileSessionEntries(previous, liveSessionsRef.current, now);

setSelectedId((current) => {

if (current && nextEntries.some((entry) => entry.id === current)) return current;

return nextEntries[0]?.id || "";

});

return nextEntries;

});

}, 1000);

return () => {

clearInterval(intervalId);

};

}, []);

This test emits a logs:stream payload with {sessionId, stream, line}, but the repo’s canonical logs:stream event contract requires {logType, raw, line, level, timestamp, filePath} (and forbids additional properties). The test should use the canonical shape (or, if the intent is to add sessionId to the contract, update the schema + emitter and then align this test with that new contract).
