Five post-merge review items from PRs #306 (clickable file paths) and
#307 (session sidebar):
- constants.js FILE_PREVIEW_EXTENSIONS gains the media extensions it was
missing vs the single-source sets in attachment-registry.ts (m4v ogv
ogg oga m4a aac flac opus), so an in-workspace .m4a opens the preview
player instead of the log viewer; new test/media-extension-parity.test.ts
pins all three copies (constants.js, panels-ui.js, attachment-registry.ts)
against each other.
- FILE_PATH_LINK_PATTERN drops `etc` from its root alternation: /etc is
unconditionally in DEFAULT_BLOCKED_TREES, so every /etc link 403'd.
Negative cases added to the link-provider and response-viewer tests.
- updateSidebarCount() counts the rows actually on the sidebar list
(session rows + web-tab rows, minus filtered-out ones) instead of
this.sessions.size, and applySidebarFilter() refreshes it so the count
follows the filter box per keystroke.
- The incremental-render connection-line gate now also fires in sidebar
layout (this._lineageEdgeCount is permanently 0 there), matching the
strip-scroll listener widened in #307, so a badge changing row heights
redraws subagent/ultracode connectors.
- isSensitivePath() blocks ~/.claude.json, ~/.claude/settings.json and
~/.claude/settings.local.json (credential-bearing by schema), anchored
to homedir() read at check time so case-level .claude/settings*.json
files stay servable in the File Viewer.

The header tab strip stops working past roughly a dozen sessions: it wraps
into two or three rows, eats vertical space and still cannot be scanned.
This adds a vertical session list in a left <aside> as an ALTERNATIVE
layout — a filter box, a live count, and a 44px collapsed rail that keeps
the ambient signal (status dot, task badge) visible.
The strip is not removed. Settings -> Display -> Tab Bar -> Session List
Layout switches between them and the default stays 'header', so existing
users see no change until they opt in.
Structure: one #sessionTabs element, two mount points. applySessionListLayout()
re-parents the SAME node between #sessionTabsHost and #sessionSidebarList,
which is why there is no second renderer and no duplicated wiring — app.$()
caches getElementById results and never invalidates them, so a moved node
keeps every existing consumer (settings-ui, webview-tabs, the generated
gesture bundle, the mobile tests) working untouched.
Notable integration points:
- Below 1024px the sidebar is an off-canvas drawer overlaying the terminal;
closed it gets inert + aria-hidden so it cannot be tabbed into, and touch
swipes over it no longer switch sessions.
- Subagent and ultracode windows anchor to the right edge of a sidebar row
instead of its bottom, connector curves follow.
- Alt+B toggles; the chord is gated out of the PTY so xterm cannot also
write ESC b into a live session.
- Collapse state lives in its own localStorage key (the settings blob is
rebuilt from DOM controls on every save) and falls back to in-memory
intent where storage throws.
Verified: frontend syntax + public asset checks, tsc, eslint, 26 new jsdom
tests, and a headless-Chromium harness (scripts/verify-session-sidebar.mts)
that renders a synthetic 25-session fleet in both layouts at 1600/1000/393px
and asserts mount point, widths, inert/aria state and row count.
