Cryptograss/Moods/performance/todo

Performance todo for the magenta Moods stack — what is open, who owns it, and what has landed. Kept by re.^[unverified]

Open

- task: Prefetch notification windows: when /api/notices/ returns a mention or answer, fetch that message window into the browser cache in the background (the payload already carries n.turn.id and n.mood), so clicking the bell opens with no spinner.
  who: magent
  kind: code
  file: memory-lane/conversations/templates/conversations/moods.html
  note: Approved by Justin 31 Oct ~01:39Z. The click is then a 0 ms jump.

^[unverified]Proposed by Re

- task: Single-shot jump for cold notification clicks: openAndReveal(slug, id) should go straight to loadAt(id) in one request (~1 s) instead of fetching the room's newest 150 first (~5 s).
  who: magent
  kind: code
  file: memory-lane/conversations/templates/conversations/moods.html
  note: Approved by Justin 31 Oct ~01:39Z.

^[unverified]Proposed by Re

- task: Dismiss the "finding it…" mask on navigation: open(slug) should immediately clear the timer, hide the box, and bump the generation counter, so a room left mid-fetch is silently dropped without painting over the room you moved to.
  who: magent
  kind: code
  file: memory-lane/conversations/templates/conversations/moods.html
  note: Approved by Justin 31 Oct ~01:39Z.

^[unverified]Proposed by Re

- task: Loading pane on entry: when entering a mood that is not completely up to date, show a short pane at the bottom with "loading" and a spinner, at about the height of the collapsed activities bar; then load the message in and scroll down, so you can see where you are.
  who: magent
  kind: code
  file: memory-lane/conversations/templates/conversations/moods.html
  note: Justin's ask 31 Oct 01:39Z, approved.

^[unverified]Proposed by Re

- task: Cache recall.py bootstrap: who_i_know() and how_i_speak() (conversations/services/recall.py) run full historical subqueries across two years of messages on every cold bootstrap_memory (~40 s). Add a daily/hourly cache.
  who: magent
  kind: code
  file: memory-lane/conversations/services/recall.py
  note: Approved by Justin 31 Oct ~01:39Z. Agent startup times, not page load.

  Answer the three open questions on the migration note (own name vs maybelle subdomain; Postgres co-located or separate; hunter stays as the agents' home?)

  decision · justin

  Only if we ever do move — the first step is tuning maybelle in place, not this.

Done

- Server bottlenecks landed and deployed 30 October 2026: PR magenta#293 (cache /api/moods/ with lifecycle busting, unblock the send flow, 4 gunicorn workers) and PR maybelle-config#240 (workers 2→4 in the Ansible-written compose). Deployed 16:09Z; measured: /api/moods/ 23.3 s → 15–26 ms, /api/moods/live/ 1.9 s → 14 ms, cold mood turns 4.0 s → 1.5–1.7 s (and 7.4 s → 3.5 s on #rabbithole), send flow fire-and-forget.
