From 4d2e6d817f65a13631f00786c45b403d7d7d58ec Mon Sep 17 00:00:00 2001 From: Adam Malczewski Date: Fri, 12 Jun 2026 18:26:00 +0900 Subject: feat(chat): chat limit — bulk quarter-unload, 75% fresh-load window, show-earlier page-in MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Long transcripts no longer grow unbounded: past the chat limit (default 256 chunks, localStorage dispatch.chatLimit) the oldest ceil(limit/4) committed chunks are unloaded in ONE bulk pass — never one-per-delta (old Dispatch's scroll-jump-per-step bug) — and only while the reader is stuck to the bottom (scrolled-up readers defer the trim; it catches up in whole quarters). A fresh page load windows to the newest floor(0.75*limit). Unloading is purely local (IndexedDB cache + server keep everything); a hiddenBeforeSeq watermark keeps history merges from resurrecting unloaded chunks, and a 'Show earlier messages' affordance pages a quarter back in from the cache with scroll-anchor preservation. Thinking-collapse render keys stay stable across trims via a hiddenThinkingCount ordinal base. - core/chunks/trim.ts: pure policy (trim/window/restore/normalize) + tests - chat store: chatLimit + canUnload deps, windowed load, showEarlier() - composition root: dispatch.chatLimit localStorage knob + unload gate wired to smart-scroll isAtBottom() - backend CR-5 OPENED (not a blocker): ?limit=/?beforeSeq= on GET /conversations/:id (courier backend-handoff-chat-limit.md) - scripts/live-probe.ts: fix pre-existing stale TurnMetricsEntry reads (m1.usage -> total.usage) that crashed the probe; 17/17 live checks pass --- AGENTS.md | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'AGENTS.md') diff --git a/AGENTS.md b/AGENTS.md index 3f7d428..a4c2f36 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -136,8 +136,10 @@ browser effects, run a LIVE probe: ## Status Slices 1–3 DONE + committed (surface system + WS; conversation transcript cache + delta streaming; tabs + model selector + DaisyUI/dracula), plus per-conversation cwd + LSP view, -context size, cache-warming (+ retention/timer), markdown, smart auto-scroll, and -multi-client live view (subscribe/reconnect + the user prompt on the event stream).
