Rename (owner ask): clicking the header title opens edit mode with the
whole title selected — typing replaces, arrows move inside. Enter or a
click away commits (PUT /api/chats/:id); Escape and an empty commit
discard. renameChat joins the ChatStore port; like saveSettings it is
NOT conversation activity — updatedAt stays put so sidebar order never
churns on a rename. The sidebar patch is instant: the header dispatches
lh:chat-renamed and SessionsSidebar folds it into its snapshot (the 2.5s
poll is only a backstop). Sidebar right-click rename is DELIBERATELY
deferred: it needs a real context-menu system, which gets its own pass
later (owner decision, 2026-09-17).
Graph chrome:
- The extraction-coverage button moves between search and import; the
gear keeps the far-right corner. Coverage still renders on an EMPTY
graph (that is exactly when it matters).
- The no-match search note no longer shifts its siblings: the chrome
row is items-start (every button is 44px tall, so top alignment pins
the row while the search container grows downward).
- Popovers dismiss properly: pointerdown anywhere outside the control's
root (button + panel) closes it, and so does Escape. Two panels can
never be open at once — the sibling chrome buttons are outside the open
root, so pointerdown closes the first before the click opens the
second. New shared hook components/popover-dismiss.ts, wired into
both the settings gear and the coverage control.
Gates: typecheck, eslint, 498/498 (+2 rename store tests), build.
Live-verified: select-all/focus/Enter/Escape/empty/blur round-trip,
updatedAt untouched, sidebar instant patch; chrome order + frozen
positions under a no-match query; popover close via canvas, search
input, Esc, mutual exclusion, toggle intact.
11 commits on fbeca36: minimal-color rounds 1-2 (phase color retired,
the braille spinner is the one working indicator; the chip is label-only),
typography rounds 1-5 (three-font rule enforced — CMU titles, Source Sans
session titles, JetBrains mono; snapped type ladder in globals.css with
the xxs rung merged into xs; lh-input caret at the font-metric floor;
session titles at prose size, message counts and active-row weight dropped,
ISO dates), header rounds 6/6b/6c/6d (60px top bar aligned to the sidebar
LH band; the open-sidebar toggle matches the close glyph at size-4 both
ways; SidebarToggle always-mounted with a lockstep animated slot — no more
one-frame title jump; title at text-3xl).
Semantic change folded in: `busy` in the chats list now means exactly "a
teach turn is in flight" — background jobs no longer spin the session row
(the sidebar's Background agents section is their channel).
Merge fallout fixed in the merge: components/graph-coverage.tsx (main's
coverage panel) held the last three text-xxs uses; with the rung deleted
they silently lost their size — mechanically swapped to text-xs, matching
lh-ui's own swap in graph-context-marker.tsx.
No file overlap with main's waves since fbeca36 (extraction coverage,
lh-graph merge, world-scale bake) — clean auto-merge. Gates: typecheck,
eslint, 496/496 tests, build. Live-verified on the dev server: 60px
header with 32px CMU title, label-only chip, snapped ladder active
(--lh-prose-size 16px, no --text-xxs rule anywhere), sidebar rows with
ISO dates, animated sidebar toggle with no header jump.
THE MESSAGE IS THE UNIT OF COVERAGE (vision-extraction-coverage.md): a
per-chat append-only ledger (coverage.jsonl) records which messages the
pipeline has extracted, by content fingerprint over exactly what the
extraction view sees (one shared line builder — core/coverage.ts); the
uncovered remainder is DERIVED at read time, never dual-tracked. A quiz
answer merging into the asking message re-opens only that message;
plan-block data-part attach never re-opens anything.
- The trigger (turn-service) replaces every-3-quiz-answers with
uncovered-tokens >= EXTRACTION.chunkTokens (4096) — quiz-less sessions
extract too, content size is the honest signal.
- runExtraction is now chunked: token-budgeted batches of the oldest
uncovered consecutive messages (a tool call + result never split), each
merged batch checkpointing its messages' coverage atomically — an abort
or error loses at most the in-flight batch; merged batches stay covered.
- Observation refs are batch-tagged (obs:<batchTag>:<sourceId>): re-runs
of the same batch dedupe; a re-opened message's fresh understanding
lands as a new event. Fixes the old obs:p1 position-collision.
- New API: GET /api/graph/coverage (exact per-session derived coverage +
running flags, most-uncovered first) and POST /api/graph/coverage/extract
(manual run for one session, 409 while in flight).
- Graph view chrome: the coverage button opens a panel with every
session's covered/uncovered tokens and a per-session Extract button —
the manual answer to aborted runs, errors, and dormant tails. Renders
even when the graph is empty: an empty graph with uncovered sessions is
exactly when it matters. Polls only while open.
- Notes imports keep the whole-file checkpoint path (coverage undefined).
- Tests: pure-core coverage suite (11), chunked-pipeline suite (3:
multi-batch + no-op, abort-keeps-earlier-batches + remainder re-run,
re-open alone + data-part invisibility), panel render suite (5);
pendingQuizAnswers and its tests deleted as dead code. 486/486.
Live-smoked on real GLM: manual extract of "teach me modal realism" ran
one batch, wrote 4 coverage entries, panel flipped to "1.3k covered ·
complete" with the button disabled, graph refetched (nodes 11), usage
persisted with real stats.
