cmdModel() had the only two root-absolute fetch('/api/...') calls left in the
frontend. Under a reverse proxy that mounts the app at a subpath (e.g.
jupyter-server-proxy at /proxy/<port>/), a root-absolute path escapes the mount
and 404s, so /model can't load the catalog or update the session. Resolve both
against document.baseURI (falling back to location.href) like every other fetch
in the frontend already does.

Add readyState !== CLOSED (2) guards to all EventSource.close() calls across
messages.js, sessions.js, panels.js, and terminal.js. Chromium reports
net::ERR_ABORTED when close() is called on an already-closed EventSource,
polluting the console during normal lifecycle transitions (session switch,
panel close, stream teardown).
Key hotspots:
- closeLiveStream() double-close via onerror → _closeSource chain
- _closeSessionEventsSSE, _gatewaySSE.onerror missing try/catch
- _kanbanStopPolling, terminal close handlers
20 close() calls guarded across 4 files, no structural changes to stream
lifecycle.
Pastes over 4000 chars or 100 lines attach as a timestamped pasted-text-*.md in
the upload tray instead of flooding the composer. Image-paste path unchanged; an
oversize paste that exceeds MAX_UPLOAD_BYTES falls through to a normal inline
paste so nothing is lost.

The outline FAB was position:fixed at z-index 9999 and could stack on top of the
scroll-to-bottom button. Anchor it inside the messages shell (position:absolute,
z-index 12) so the two controls don't overlap.

- Hamburger button: 32x32 -> 44x44 tap target (iOS HIG minimum), SVG icon
20 -> 24px. flex-shrink:0 preserved; spacer keeps the title centered.
- Edge-swipe-to-open-sidebar: edge zone 28 -> 80px, trigger 72 -> 64px, max
vertical 48 -> 56px; removes the _isPwaStandalone() gate in
_onPwaSidebarSwipeStart so the gesture works in a normal mobile browser, not
only the installed PWA. Still _isDesktopWidth()-blocked, touch/pen-only,
interactive-target-excluded, and requires horizontal intent (dx>=64 &&
dx>|dy|*1.5), so scroll/tap won't trigger it.
Known tradeoff (Nathan-approved ship-as-is): in mobile BROWSER the 80px left
edge zone overlaps iOS Safari's back-swipe; degrades gracefully (PWA, the
primary mobile target, has no back gesture).
Verified live at 390x844: hamburger renders 44x44 + tap opens sidebar; a
left-edge swipe opens the sidebar in a non-PWA context. 66 existing mobile/
swipe/titlebar tests pass.

Paused/disabled cron jobs are partitioned out of the active list into a
collapsible 'Paused (N)' <details> section so they don't drown the active
jobs. _cronList stays the single source of truth — only the render is split,
so openCronDetail / _cronNewJobIds / detail-refresh are untouched. Reuses the
already-translated cron_status_paused label (zero new i18n keys). Collapsed
state persisted in localStorage.
Maintainer polish on absorb: wrapped both localStorage read/write in try/catch
(repo convention — a storage throw in private mode must not dump the cron
sidebar into the error banner) + added the CHANGELOG entry.

Two coherent fixes for the #4346 transcript-virtualization scroll-jump
cluster, shipped together (contributor-approved) because both touch
static/ui.js + the same virtualization test file and interact (the
cache-reset path uses the per-role default from #4367). Both only run when
the default-OFF experimental "Virtualize long transcripts" setting is on.
#4367 — per-role virtual scroll height estimates:
Replaces the flat 140px unmeasured-row estimate with per-role fallbacks
(user 120 / assistant 160 / tool_call 400 / default 140) via
_messageVirtualDefaultHeightForRole + _messageVirtualRoleForEntry, so
tool-call rows (which measure 500-2000px) aren't under-counted before
measurement. Additive + backward-compat (opts.roleForIdx optional → flat
default when absent). The two sibling offset calculators route through the
per-role defaults too.
#4368 — anchor-based scroll compensation during measurement:
Adds _compensateScrollForMeasurementDelta (capture anchor + scrollTop →
render → re-pin scrollTop by the anchor row's measured delta; null/missing/
<2px guards; programmatic-scroll flag managed) wrapping
renderMessages({preserveScroll:true}) in _scheduleMessageVirtualizedRender,
plus a 150ms scroll-active guard deferring measurement refresh while the user
scrolls, and session-switch cleanup of the three scroll-settle globals.
Maintainer note: combining the two required the test harness for
test_clear_height_cache_resets_scroll_settle_globals (#4368) to also eval
_messageVirtualDefaultHeightForRole + define MESSAGE_VIRTUAL_DEFAULT_ROW_HEIGHTS
(#4367), since the combined _clearMessageVirtualHeightCache resets the estimate
via the per-role helper. Both PRs' test sets retained.

Adds WebUI controls to manage the messaging gateway lifecycle without a
terminal. _handle_gateway_lifecycle routes start/stop/restart to the
existing platform-aware `hermes gateway {action}` CLI via a list-argv
subprocess (no shell), scoped to the active profile, with bounded
timeout/error handling and a status-card refresh. Auth + CSRF gated;
profile name charset-validated; stdout/stderr never leaked to the client.
Maintainer hardening (warm-up SHOULD-FIX): added _GATEWAY_ACTION_LOCK, a
server-side single-flight guard. The client disables its button in-flight,
but a scripted authed client could otherwise fire overlapping
start/stop/restart calls and spawn concurrent gateway subprocesses. A
non-blocking acquire now returns 409 on contention (mirrors the self-update
_apply_lock pattern), released in finally. Added a regression test
(toothless-checked: without the lock the 2nd action spawns a subprocess +
returns 200).
Cross-platform: delegates to the mature hermes_cli gateway subcommand
(systemctl/launchctl), pathlib paths, PYTHONUTF8=1 + BROWSER=echo in env.

The inline PDF preview rendered only page 1, so multi-page documents
looked clipped. loadPdfInline now renders every page (capped at MAX_PAGES=20
for memory) sequentially into a scrollable .pdf-preview-body, shows the page
count in the header, and appends a "Showing the first N of M pages" notice
(pdf_truncated, 13 locales) when the PDF exceeds the cap.
Robustness: renderPage(i) attaches each canvas only AFTER its render
promise resolves, and a per-page failure is caught and skipped
(`.then(()=>renderPage(i+1)).catch(()=>renderPage(i+1))`) so one corrupt
page can't halt the preview or surface an unhandled rejection. XSS-safe
(esc(fname), t() with numeric args).

"Reply with selection" no longer appends the selected text straight into
the composer. It now adds a named chip ("Context N") to a row above the
message box (composerSelectionChips). Chips can be renamed (double-click,
esc()-escaped) or removed (x); multiple stack. On send(),
_flushSelectionBlocksToComposer() materializes pending blocks into the
composer as **Name:** + markdown-quoted text, then the normal send path
runs unchanged on composer.value.
Regression-safety:
- _flushSelectionBlocksToComposer early-returns when no blocks are pending,
so send() is byte-identical for anyone who never uses the feature.
- loadSession() AND newSession() both clear pending blocks before replacing
S.session, so chips never leak across a sidebar switch OR a New Chat
(the New Chat clear + its regression test were added per Codex review).
- chip name/text rendered via esc(); XSS-safe.
Verified live (headless CDP drive): add/render/remove/rename, flush
produces correct markdown, empty-flush no-op, session-switch clears,
injected <img onerror=...> chip-name escaped (not executed).

Surfaces the Hermes agent's LLM Wiki as a read-only knowledge-base
observability section in Insights (status counts + browsable read-only
pages). Unconfigured shows a clear "Unavailable" empty state.
Strictly read-only, auth-gated. The wiki file-serving path is hardened
against the full traversal/symlink/TOCTOU class (Codex + Opus review, each
vector regression-tested + toothless-checked):
- _llm_wiki_page_files resolves the wiki root once as the trust base;
skips a section whose resolved path escapes the root; requires each *.md
target's RESOLVED path under both real root and real section; rejects
dot-prefixed segments on lexical AND resolved-relative paths (closes
symlink-to-hidden/out-of-tree + symlinked-section escapes). Browse + read
share this allowlist.
- /api/wiki/page rejects abs paths + a real '..' SEGMENT (legit v1..v2.md
still opens); requires the resolved target in the allowlist; reads the
resolved path with O_NOFOLLOW; and fstat-verifies the open fd's
(st_dev, st_ino) against the identity captured at allowlist time — closing
final-component AND parent-directory symlink-swap TOCTOU races. Any
mismatch/vanish -> clean 404, never a 500.

Docker images and pip installs have no .git directory, so _check_repo
returned None and the frontend interpreted both update-target parts being
falsy as "Up to date" — a stale Docker image would misleadingly look
current. _check_repo now returns a minimal sentinel dict ({name, behind:
None, no_git: True}) instead of None so the Settings panel can distinguish
"can't check" from "up to date", and _formatUpdateTargetStatus /
checkUpdatesNow surface a localized "Can't check for updates" state
(settings_update_no_git, added across all 13 locale blocks). In mixed
deployments where one component has a git checkout and the other does not,
the valid git-side update info is still shown. The sentinel's behind: None
flows safely through the existing notification/summary builders, which all
gate on int(info.get('behind') or 0) > 0.

When the model dropdown rebuilds (panel switch, provider refresh, or a
live-model fetch that times out and serves a fallback catalog), a
cross-provider selection could vanish from the refreshed catalog and the
browser would snap the <select> back to its first <option> (the default
model). _reconcileModelDropdownSelection now routes each selection branch
through an _applyOrEnsure helper that delegates to
_ensureModelOptionInDropdown, re-injecting the chosen model as a custom
option when it is missing from the rebuilt catalog instead of returning
null. Branch order and per-branch model/provider arguments are unchanged.
Maintainer note: simplified the contributor's helper to delegate straight
to _ensureModelOptionInDropdown (which already applies-first-then-injects),
removing a redundant double scan; re-pointed the
test_populate_model_dropdown_reconciles_selection_after_rebuild string
assertions to the new form (the behavioral node-driver tests for boot-default
precedence and in-page selection preservation are unchanged and still pass).

Ships @dso2ng's fix: /api/session now reconciles stale CLI source flags
against the state.db WebUI-origin row, and _isExternalSession() refuses to
classify an explicit WebUI-source session as external — so a WebUI-native
transcript with a stale sidecar isn't force-reloaded like an imported one.
Rebased onto master (contributor's net code-diff applied; byte-identical to
PR head). CHANGELOG stamped v0.51.474.

The paste handler (boot.js) bailed entirely when the clipboard contained
both text and image items, preventing image attachment in the most common
real-world scenario: right-click → Copy Image from browsers, Notes, Slack,
etc. — these almost always carry a text/html or text/plain representation
alongside the image.
Previous behavior (from #1620 fix):
- clipboard has text only → normal text paste (correct)
- clipboard has image only → attach image (correct)
- clipboard has BOTH → text pasted, image silently dropped (wrong)
New behavior:
- clipboard has text only → normal text paste (unchanged)
- clipboard has image only → preventDefault + attach image (unchanged)
- clipboard has BOTH → let text paste normally AND attach image
The key change: preventDefault() is now only called when no text is
present (true screenshot paste), so the browser handles text insertion
naturally while addFiles() runs regardless.
Fixes the regression introduced by the #1620 fix. Closes#1620.
Codex+Opus review fixes:
1. Index query missed the common toggle shape <label><input><span data-i18n>>
— only label[data-i18n] was indexed, so most checkbox settings (Virtualize
long transcripts, Browser notifications, etc.) were silently unsearchable.
Broaden to 'label[data-i18n], label [data-i18n], label' and make
_resolveSettingsField resolve any [data-i18n] node to its .settings-field.
2. Stale async-render race: _beginSettingsPanelSession now bumps
_settingsSearchSeq + clears the input/results, and the outside-click dismiss
handler also bumps the seq, so an in-flight index build from a prior session
can't paint into the dropdown. + 4 regression tests.
Ships @rodboev's searchable-settings feature (#3850/#3936): a search box in
Settings that finds any field across all 5 sections with breadcrumbs +
click-to-navigate+highlight+clear. Rebased fresh onto master (post v0.51.470),
5 feature files byte-identical to PR head, re-stamped v0.51.471 (was v0.51.469,
collided with the shipped transcript-virtualization release).

Virtualization (#500/#4214) caused a scroll-up flicker on long sessions with
tall tool-call rows (variable-height anchor oscillation), distinct from the
stream-completion jump fixed in #4325. Per maintainer decision, flip the
'Virtualize long transcripts' preference to experimental/opt-IN (default OFF)
for everyone until the scroll behavior is reliable.
- api/config.py: virtualize_transcript default True->False; add
virtualize_transcript_optin marker (both bool-allowlisted); load_settings
force-off migration — a stored true WITHOUT the post-flip opt-in marker is
reset to off, so 100% of existing users land on off; an explicit opt-in
(marker present) is honored.
- boot.js / panels.js: default-off semantics (===true), persist the opt-in
marker on enable, checkbox not pre-checked.
- index.html / i18n.js (en): relabel experimental + flicker warning.
- Tests: rewrite the #4325 toggle assertions for the opt-in contract + 4 new
migration tests (unset/stale-true/explicit-optin/marker-without-true).
Phase B (root-cause scroll-stability) tracked separately. Thanks @b3nw.
The opt-out toggle's change handler wrapped renderMessages in a silent
empty catch. Keep the defensive try (a toggle must never wedge the
settings handler) but console.warn on failure so a broken render is
diagnosable instead of swallowed.
Adds a Preferences setting 'Virtualize long transcripts' (default ON, opt-out).
When disabled, _currentMessageVirtualWindow returns a full non-virtualized window
so the entire transcript renders at once (also short-circuits the virtual
re-measure loop). Server-persisted (virtualize_transcript bool, default True),
hot-applies via renderMessages on toggle. i18n in all 13 locales.
Pairs with @rodboev's #4328 stream-end anchor scroll fix (cherry-picked into
this branch) to fully resolve#4325.
