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).
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.
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).

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.
A poisoned cache row {name:'x', model:{}} passed the name-only cache predicate
but threw 'p.model.split is not a function' synchronously on profile-chip click,
bricking profile switching until localStorage was cleared. Guard both render
sites (typeof p.model==='string') and reject unsafe model types in
_profileDropdownDataCacheUsable; regression covers {model:{}} and {model:123}.
