From a8bb389cd61ac05135b20297950de02c340d006c Mon Sep 17 00:00:00 2001 From: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 Date: Wed, 8 Jul 2026 14:18:17 -0400 Subject: [PATCH] fix(desktop): render archived observer history for idle agents and reset paging on channel switch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit F7 — idle agent archived history not renderable (CRITICAL): getAgentObserverSnapshot and getAgentTranscript were early-returning empty when enabled=false, discarding ingested archived events. The enabled flag conflated two concerns: subscribing to the live relay, and reading stored data. Only the relay subscription should gate on isLive/hasObserver. Fix: drop the !enabled early-return in both store readers; keep !agentPubkey as the only guard. The enabled parameter is retained for call-site compatibility (renamed to _enabled) but no longer controls store reads. The relay subscription useEffect in useObserverEvents still gates on enabled so idle agents don't trigger unnecessary relay connections. Also fix the EmptyObserverState gate in ManagedAgentSessionPanel: previously shown whenever !hasObserver regardless of content, now only shown when the agent is idle AND there is nothing to display (transcript.length === 0 && events.length === 0). This allows archived channel history to render for idle agents instead of showing the empty state. F8 — archive paging state not scoped to channel (IMPORTANT): useLoadArchivedObserverEvents held hasOlderArchived, cursorRef, and isFetchingRef in a single hook instance while channelId changed across channel switches in the same AgentSessionThreadPanel lifecycle. Channel A's exhausted state and cursor bled into channel B — B would not page, or B's first read would skip rows newer than A's cursor. Fix: add a useEffect([channelId]) that resets cursorRef to null, isFetchingRef to false, and hasOlderArchived to true on channel change. Backfill state (backfillStatusRef/backfillPromiseRef/backfillResolveRef) is identity-level and deliberately NOT reset — backfill covers all channels and only needs to run once per identity mount. Tests: two new regression cases in ingestArchivedObserverEvents.test.mjs: - test_idle_agent_archived_events_readable_when_enabled_false: idle agent with archived rows for two channels reads both (enabled=false no longer blocks), and scopeByChannel returns only channel-A frames for channel A with zero channel-B contamination. - test_channel_switch_resets_cursor_and_exhaustion: verifies the paging state-machine semantics — channel A exhausted then channel switch resets cursor/hasOlderArchived/isFetching. Plus a spec test confirming backfill state fields are identity-scoped and must not reset on channel switch.
