The themed WebKit scrollbar skin keeps a wide table's horizontal bar
permanently painted. Chromium never repaints state-conditioned scrollbar
styles (hover-conditioned ::-webkit-scrollbar* rules and :hover
scrollbar-color changes both compute but never reach the painted bar,
measured headed and headless), so the hover reveal toggles overflow-x
itself: hidden at rest with a padding-bottom matching the themed bar
height, auto on hover or keyboard focus with the padding released — the
appearing bar exactly replaces the padding and nothing below shifts.
Resting hidden overflow drops Chromium's implicit scroller focusability,
so wide wrappers carry an explicit tabindex for arrow-key scrolling.
Cache README (EN/ZH): the medium is the session_projcache domain in
per-record layout (one version-stamped document per session under the
json backend root), reads are synchronous from the domain's in-memory
tables, and the storage stack rides in base. storage-json README
documents both layouts and their contracts; web-app README notes that
storage and the projection cache live in the shared base. Regenerated:
session-projection subsystem catalog (sync cachedSnapshot, domain
medium), config-catalog (Config.root gone), module-graph (cache now
depends on storage-domain, not session-persistence), cli composition
(storage rows in base), and the projection-cache Agent Note — which now
records the file-root revision and its revert as rejected alternatives.
- subsystem docs: drop the removed persist flag from the ProjectionDefinition
type block (both languages).
- config-catalog regenerated (cache requires sessionProjections/sessions,
config gains root) and the zh side synced by hand; doc graphs regenerated.
- Agent Notes: the per-session cache note records the owned root tree and
no-persistence design; the storage-root proposal's link to it is corrected
(two levels up).
The web e2e seeds no longer warm the deleted coldSnapshot; assertions do not
depend on the cache path. list-children mounts the cache with a scratch
root instead of a storage-domain backend, and drops the now-unused storage
devDependencies.
Replace the single global session_projcache domain with a per-session
cache file inside the session's own persistence directory, resolved
through sessionPersistence.locate(meta) — the persistence backend owns
the session-directory layout, the cache service keeps every checkpoint
and cold-read responsibility.
- cachedSnapshot(meta) becomes async (one file read per session);
coldSnapshot takes the session header so it can locate the file, with
the stored log header remaining the identity witness.
- Backends without a per-session directory (sqlite) disable the durable
cache: writes no-op and cold reads fall to the full-log rung. An
obsolete global cache is never read — derived data refolds on first
cold read (no migration).
- writeAtomic is exported from dsh-storage-json as the shared atomic
whole-file replace primitive; api-proxy listing and subagent cold
reads await the now-async cachedSnapshot.
- READMEs and a new Agent Note document the per-session medium.
Markdown tables were always rendered at natural width, so anything wider
than the 748px message column could only be read through horizontal
scrolling. Following the deepsuite chat TableWrapper treatment: tables
under four columns (and any table inside a blockquote) now fill the column
and wrap cell text down to the cells' minimum readable width, while
four-or-more-column tables keep their natural width behind the wrapper's
horizontal scroll and carry the stable md-table-wide hook. The chat
transcript widens hooked tables past the message column with a pure-CSS
container-query breakout (100cqw against ChatView's scroll container
standing in for deepsuite's JS-measured list width), keeping the table
content aligned with the message column and clamping to neutral when the
transcript is narrower than the column.
- Translate the zh Agent Note's title and section headings and align
its rail terminology with the established zh READMEs (轨道).
- Disambiguate 'the browser's listener' to WorkspaceBrowser's in the
English note.
- Record the in-flight outside-click exception in the ui-workspace
README (both languages) and the owning workspace-sidebar feature
note, cross-linked to the bug-fix note.
- Add an apps/web real-browser scenario pinning the document-level
bubble the jsdom test cannot replay: one real rail click must leave
the search expanded and focused, and a genuine outside click must
dismiss it afterwards. Negative-controlled against the unguarded
code (fails in 12s on the aria-expanded assertion).
- Register the new e2e file in the host tsconfig face and the client
face's exclude list.
The message-feedback note editor previously expanded inline inside the
assistant message's shared IconActions row, overflowing the row at every
viewport and pushing the branch action and the clock out of the column.
Rework it into a portable popover: the note editor is a fixed-position panel
portaled to document.body and anchored to the note trigger, so the row keeps
its single 28px line whether the editor is open or not and the panel escapes
the column's overflow clip.
The like/dislike buttons and the note trigger stay in the row unchanged; the
trigger toggles the popover (textarea + Save/Cancel + note-save failure) which
auto-focuses the input and closes on Escape or an outside click, returning
focus to the trigger. Rating/list-load failures surface in the row, note-save
failures inside the popover. Reuse the Menu portal surface tokens and add
@types/react-dom so the createPortal usage typechecks.
Layout e2e sweeps six viewports and pins that opening the editor leaves the
row's overflow, line count, and out-of-column items unchanged, and that the
panel is outside the column, within the viewport, and anchored to its trigger.
Unit tests cover the popover's portal-to-body, toggle, Escape/outside-click
dismissal, and unmount early-returns.
