test_branch_endpoint_consults_foreign_session_guard_on_missing_sidecar
grepped the inline handler block for _claim_or_synthesize_cli_session +
not_claimable + 403 — but #5449 extracted that logic into the
_load_branch_source_or_refuse helper, leaving only a dead comment carrying
the old text to satisfy the grep. Point the test at the helper so it asserts
real post-refactor structure instead of a comment.
- Add test_profile_model_selection_accepts_model_in_overflow_extra_models
(the extra_models overflow-bucket regression test the warm dossier flagged
as the #5453 ship-pass note).
- Drop the stray dead pseudo-code comment left in handle_post branch route
(#5449 cosmetic nit).
Removes the #liveAssistantTurn .transparent-event-row entrance animation
rule and its now-unused @keyframes transparent-event-enter, eliminating the
entrance-animation replay on streaming rebuilds that remained after the
#5400 identity-reconcile fix. Depth-fade [data-transparent-fade] rules
preserved (avoids the #5406 opacity-clobber). Follow-up to already-closed #5367.

Add a dedicated visibilitychange hook for the 60s relative-time refresh poll so skipped hidden-tab ticks repaint immediately when the tab becomes visible, even when no streaming poll is active.
The 30s streaming poll (renderSessionList -> GET /api/sessions + full sidebar
rebuild) and the 60s relative-time refresh (renderSessionListFromCache -> full
DOM rebuild) ran unconditionally, including in hidden background tabs, so a
backgrounded window kept fetching and rebuilding the sidebar it could not show.
Guard both interval callbacks with document.hidden and refresh the list on
visibilitychange when the tab is shown again, mirroring the existing gateway
poll. Visually neutral while the tab is visible; a hidden tab simply stops
burning network and DOM churn and re-syncs the moment it is shown.
Verified: node --check + ESLint runtime guard clean.

The 30s streaming poll and the gateway poll re-applied /api/sessions and ran a
full sidebar DOM rebuild (list.innerHTML='' + one node tree per row) on every
tick, even when the payload was byte-identical to what was already on screen —
the common case on an idle sidebar.
Add a signature over the applied rows + projects + coarse display state in
_applySessionListPayload and skip renderSessionListFromCache() when it matches
the last rendered signature and no entrance animation is pending. A streaming
row's fields advance each poll so its signature changes and it still repaints;
client-only display toggles (search, active, density, select, lineage
expansion) render through their own paths. The per-refresh INFLIGHT cleanup is
still run on the skip path. The 60s relative-time refresh and all other render
triggers call renderSessionListFromCache directly and are unaffected.
Output-neutral: a skip only happens when the render would produce the same DOM.
node --check + ESLint runtime guard clean.

Two O(n^2) costs on the per-token/per-frame streaming path, both over the
growing answer:
WS2.2 — snapshotLiveTurn() serialized the whole live turn via turn.outerHTML on
every render frame. That snapshot only backs mid-stream session-switch restore,
and the switch path (sessions.js) plus tool/done event boundaries already
capture synchronously, so the per-frame call is throttled to a coarse trailing
snapshot instead of serializing the entire growing DOM each frame.
WS2.3 — the token handler ran _parseStreamState() (strip tool-call XML + extract
inline thinking over the FULL accumulated text) on every token, but _doRender
re-parses once per throttled frame anyway and the only per-token use is the
assistant-row creation gate. Skip the parse once the row exists (the common
case); keep it only until the row is created. Also drop the full-string
toLowerCase() allocation in _stripXmlToolCalls for a non-allocating regex test.
Output-neutral: same rendered DOM; the row-creation gate and snapshot semantics
are preserved (row appears within one 66ms frame; switch/settle snapshots stay
synchronous). node --check + ESLint runtime guard clean.

read_importable_agent_session_rows() is a pure read, but it opened a
read-write sqlite connection on the live multi-GB WAL state.db and re-ran a
defensive CREATE INDEX self-heal on every sidebar build. Holding a
write-capable handle while the agent streams into the same DB adds needless
checkpoint/lock surface.
Open the DB read-only (file:...?mode=ro) for the projection, and self-heal a
missing idx_messages_session through a separate short-lived writable
connection only. With the index present (the normal case) the read path
performs zero writes; when it is missing the self-heal still runs and rows
still come back.
Behavior-neutral: identical rows when the index exists; self-heal preserved
when missing; read-only-fs degradation to the pre-aggregated path unchanged.
Tests: tests/test_issue5455_listing_readonly_connection.py (read-only open,
no writable connection when index present, self-heal when missing).

In compact-worklog mode the anchor activity scene re-renders every frame, and
its live prose row was rebuilt with renderMd(fullText) each time — re-parsing
the entire growing answer per frame, which is O(n^2) over a long streamed
response (the incremental smd parser that the main body already uses was
bypassed and its segment hidden).
Keep a persistent per-segment smd parser + DOM node (keyed by the prose row's
local_id, using the same safe renderer as the live body) and feed it only the
delta each frame; hand that persistent node back to the scene builder instead
of re-parsing. Turns the per-frame prose cost from O(n) into O(delta), i.e. the
whole answer from O(n^2) to O(n).
Safe by construction: settled rows and any failure (no smd, no stable key,
parser error, text divergence) fall through to the existing renderMd path, so
worst case is identical to today. Cache is bounded (<=32 segments) and self-heals
on non-append text changes, mirroring _smdWrite.
Verified: node --check + ESLint runtime guard clean. Streaming render profiled
in-browser via a per-frame timing probe.

Codex re-gate found 2 SILENT regressions the certifier missed:
- inline lost the 'Fit to screen' toolbar button (PR gated Fit to lightbox-only)
- the new readable-scale/envelope path leaked into lightbox mode (changed zoom-out floor + fit init for wide diagrams)
Fix: toolbar restored to master shape (Fit for all modes, Fullscreen inline-only);
_minScale() returns the flat _MERMAID_VIEWER_MIN_SCALE for lightbox; lightbox init
restored to master's _fitScale()/box*initialFit; the new readable-height sizing is
now scoped strictly to inline mode. Tests updated to the master-consistent contract.
