Memory: get_state_db_session_messages had no SQL LIMIT — it full-scanned the
state.db messages table and fetchall()'d into a Python list. The display path
(GET /api/session) already has a careful since_timestamp optimization that
bounds the common uncompressed tail load, but it deliberately bails (returns
None) on compressed sessions (truncation_watermark/boundary) and msg_before
paging — in those cases the read used to full-scan with no cap. A
pathological/huge state.db could then materialize unbounded rows into memory.
Add an opt-in `limit` parameter to get_state_db_session_messages (applied as a
SQL LIMIT that keeps the NEWEST rows via a DESC subquery re-sorted ASC). It is
a BACKSTOP, not a semantic window: the display window counts visible rows
post-reconciliation, so a true window LIMIT here would corrupt the
sidecar/state.db merge (see _state_db_since_timestamp_for_limited_display,
which deliberately does NOT SQL-LIMIT raw rows for exactly that reason).
Thread a generous _STATE_DB_DISPLAY_ROW_BACKSTOP (50000) from the GET /api/session
display caller only. The full-history model-context callers (reconciliation at
models.py:3437, context reconstruction at :8576, new-turn context at
streaming.py:8443) do NOT pass a limit — their semantics require the full
history, unchanged.
Test: tests/test_state_db_read_backstop.py — no-limit returns full history
oldest-first (model-context contract unchanged); limit=N keeps the newest N
re-sorted oldest-first; limit > row count returns all; limit<=0 clamps to 1
(newest); invalid limit falls back to unbounded; limit composes with
since_timestamp. Existing state.db active-filter + reconciliation suites (54
tests) unchanged.
Contract Routing
- Task type: memory-bound fix (unbounded state.db row materialization on the
display path's bail cases).
- Touched areas: state.db message reader (api/models.py) + GET /api/session
display caller (api/routes.py). NOT the model-context callers.
- Relevant public docs: AGENTS.md, CONTRIBUTING.md, docs/CONTRACTS.md,
docs/rfcs/webui-run-state-consistency-contract.md (Model context layer).
- State layer mutated: none (read-only). The model-context read path is
UNCHANGED (no limit passed) — Invariant 1 (visible current turns enter model
context) and the reconciliation contract are preserved. Only the display path
gets the defensive cap, which does not affect what the agent receives.
- Scope boundaries: this is narrower than a naive "add LIMIT everywhere" —
_state_db_since_timestamp_for_limited_display's docstring explains why a
semantic window LIMIT would corrupt the merge; this cap is purely a
pathological-input safety net above any legitimate session size.
Release note: GET /api/session's state.db read now has a defensive row backstop,
capping memory when the bounded since_timestamp optimization bails on
compressed/paged sessions.
Model Used: builtin:zai-coding-plan/GLM-5.2 (ZCode agent).
Centralize custom-provider model-ID extraction into _configured_model_ids()
+ _configured_model_options(), used by both catalog construction and runtime
routing so the picker and resolver can't drift. Fixes list-shaped
custom_providers[].models allowlists silently staying on the default provider
instead of routing to their own (#6121). Existing mapping / list-of-strings
configs unaffected.

Reconcile the gateway pending-mirror in _session_attention_summary()
before counting sidebar approval attention, so a parent session's red
approval dot clears once the underlying gateway approval has drained.
Live approvals stay visible; clarify fallback unchanged. WebUI read-path
mitigation; child-session context-propagation root cause stays in #6100.

The composer model dropdown (#composerModelDropdown) is a child of
.composer-footer, which sets container-type:inline-size (and, under the Geist
Contrast skin, a backdrop-filter). Both establish a fixed containing block, so
the phone position:fixed dropdown resolved against the FOOTER (pinned to the
bottom of the screen) instead of the visual viewport — dropping the menu below
the fold on all skins (the "tapping the model picker does nothing / opens
off-screen" symptom in #6080).
Fix (Fable UX gate recommendation on PR #6105): on the phone path
(<=640px) reparent the dropdown to <body> and switch it to position:fixed via a
.model-dropdown--floating class, exactly the working #profileDropdown idiom, so
fixed positioning is viewport-relative on every skin. The visualViewport math
from PR #6105 is preserved (viewport-relative coordinates, above/below flip
preferring the larger space, width = viewport - 16px, titlebar-bottom clamp) and
so are the rAF-coalesced visualViewport resize/scroll listeners.
Desktop (>640px) is unchanged: closeModelDropdown() and the desktop branch of
_positionModelDropdown() restore the element into its original .composer-footer
slot and clear the phone inline styles, so the desktop popover stays an
absolutely positioned footer child, byte-for-byte identical to master. Because
the menu now leaves the footer on phones, no per-skin backdrop-filter override
is needed.
Adds tests/test_issue6080_model_picker_reparent.py, including a node-executed
DOM-parentage guard that runs _positionModelDropdown()/closeModelDropdown()
against a stub DOM and asserts the open phone dropdown has NO .composer-footer
ancestor (escaping the container-type trap) and is restored into the footer on
close and on desktop.

Three fixes in one commit:
1. **CI test mock** — Added addEventListener/removeEventListener to the
Node.js makeElement mock so viewport.addEventListener() calls in the
touch handler registration don't crash with 'not a function'.
2. **Two-finger pan during pinch** — Replaced _setScale() call with
direct transform math. The new formula computes scale and position
simultaneously:
ratio = boundedScale / pinchStartScale
x = currMidX - (startMidX - startPosX) * ratio
This keeps the diagram under both fingers regardless of midpoint
drift, enabling simultaneous zoom + pan.
3. **Post-pinch click suppression** — _onTouchEnd now sets dragged=true
when exiting pinch mode so any synthesized click event is caught
by the existing dragged guard in _openViewerOnClick instead of
opening the lightbox.
Codex re-gate found the same derived-title leak on the sibling /api/sessions/search
endpoint (3 branches redacted only 'title'). Extract _redact_sidebar_title_fields()
shared helper, apply it in both _sidebar_session_response_item and all 3 search
branches, read api_redact_enabled once per search response (mirrors #4662). +helper
test + source-guard that every search branch calls the redactor.
Codex gate found the #6056 derived display_title (from raw user-message content)
bypassed sidebar redaction — the serializer redacted only 'title', so a credential
in a delegated goal leaked to the sidebar even with api_redact_enabled=True.
Redact display_title + _state_db_title + parent_title on the same path; +regression
test (proven to fail on the unfixed serializer).
Codex gate found the eviction-reorder made never-saved empty shells immortal
(abandoned /api/session/new tabs accumulate unbounded past sessions_cache_max).
Add a grace-window bound: protect a never-persisted empty shell only while fresh
(<30min old) OR while it carries a composer draft; a stale, empty, draftless,
never-saved shell is treated as abandoned and becomes evictable again. A real
compose persists a draft on the first keystroke (disk-backed + reloadable), so
the brick fix is preserved while the leak is closed. +2 regression tests.
Two independent defects that chain into "new conversations cannot be started":
every POST /api/session/draft and /api/chat/start 404s a few seconds after
POST /api/session/new returned 200.
1. Search inputs are parsed as username fields.
index.html contains no <form> at all, but does contain password inputs (the
Settings "Access Password" panel). Chromium therefore groups the document's
unowned fields into one synthetic password form and picks the first text input
in the DOM — #sessionSearch, the sidebar conversation filter — as that form's
username field, then autofills the saved account name into it on load.
autocomplete="off" was already present; it is ignored for credential
heuristics.
The autofill fires oninput -> filterSessions() -> GET /api/sessions/search
?content=1&depth=5: a full content search the user never asked for, repeated
on every page load.
Fix: give the four search inputs type="search" plus the per-manager opt-outs
(data-1p-ignore / data-lpignore / data-bwignore / data-form-type), and give the
Settings password inputs a real <form> owner with proper autocomplete tokens so
Chromium scopes the credential form to them instead of to the whole document.
The form uses display:contents, so layout is unchanged. CSS suppresses WebKit's
native search clear button, since these fields ship their own
(#sessionSearchClear).
2. A never-persisted session is treated as evictable.
new_session() intentionally keeps a session in RAM until its first message
(#1171), so the SESSIONS cache is its only copy. _session_is_evictable()
(#4765) short-circuited on zero messages, reasoning that an empty shell "is
recreated on next access". It is not: get_session() has no recreate path and
raises KeyError, so both routes 404 and the session can never be started.
The content search from (1) pulls every hit through get_session(), which blows
past sessions_cache_max (default 300) and evicts the session being composed.
That is why this reproduces within seconds on an install with ~1700 sessions,
and why it grew worse as the session count rose.
Fix: require proof of persistence before evicting, for empty sessions too —
which is what the function's own docstring already promised ("Its full state is
already persisted to the JSON sidecar"). The zero-message branch was the single
path that bypassed it. #4765's memory bound is unaffected: sessions loaded from
disk remain evictable, and its existing tests still pass.
Trade-off: an unsaved empty session now stays resident for the process
lifetime (one per "New Conversation" click, an empty object each). That is a
deliberate application of the function's stated invariant — "slightly more RAM
for a session we are unsure about is strictly better than evicting an unsaved
session". Bounding it by age instead would also work if maintainers prefer.
Validation:
pytest tests/test_issue4765_sessions_lru_eviction.py -> 9 passed
The added regression test fails on the unpatched predicate (verified by
reverting api/models.py alone) and passes with the fix.
Note: (1) fixes what triggers the churn, (2) fixes what turns that churn into
an unstartable session. Either fix alone leaves a real defect in place, so
they are submitted together.

Gate review follow-ups for the #6022 no-leak rule: every non-deliberate
newSession/session-new call site passes worktree:false; only deliberate
New Chat inherits the config default.
- Strict boolean config read: only YAML true enables the default;
quoted strings/ints/lists/dicts/null fall to the safe no-worktree
default instead of truthiness-coercing.
- Presence-based explicit detection: 'worktree' in body — an explicit
worktree:null is an opt-out, never a fall-through to config.
- Guarded remaining auto-mint call sites with explicit worktree:false:
profile switch (panels.js), promptWorkspacePath + switchToWorkspace
blank-page binds (panels.js), promptNewFile + promptNewFolder
(ui.js), terminal auto-session (commands.js).
- Tests: worktree:null vs config-true (factory must not be called),
strict-boolean malformed-shape matrix, static regression gates for
every auto-mint site + a bare-body sweep so future auto-mint paths
can't silently omit the key; updated the cmdTerminal preflight
assertion for the new call shape.
/api/session/new treated an absent 'worktree' key as false, so the
agent's config-level 'worktree: true' default was never consulted for
WebUI sessions even though the WebUI reuses the agent's own worktree
helper. Both callers should agree on same-agent/same-repo isolation.
Three-value model:
- body 'worktree' absent -> agent config default applies (profile-aware
via get_config_for_profile_home, so a user with worktree:true in one
profile but not another gets per-profile behavior)
- explicit true/false -> honored verbatim; explicit always wins
Non-git workspaces: a config-default request degrades to a plain
session and surfaces 'worktree_skipped' in the payload; an explicit
worktree:true keeps the hard 400.
Frontend (same change, load-bearing): newSession() forwards explicit
true/false and omits the key otherwise; the boot-time auto-bind
(_maybeBindFreshDefaultWorkspaceSession) and the onboarding session
send worktree:false explicitly so a config default can never mint a
worktree + branch from merely opening the UI. Deliberate 'New Chat'
sends nothing and inherits the default.
Tests: route matrix (config on/off x body absent/true/false), non-git
fallback vs explicit 400, explicit-false-beats-config-true, config
helper (ambient/named-profile/fail-soft), static UI assertions that
auto-bind and onboarding opt out and New Chat paths don't pin a value.
Fixes#6022
Maintainer revision of #5806: the localization refactor (all profile-concept
help text now goes through t() so it's translatable via the documented
English fallback) is the core value, and the concrete Example row genuinely
clarifies how profiles + workspaces work together. The Binding row restated
the Together row + added scheduled-task edge-case trivia that muddied a concept
explainer, so it's dropped (row + its 2 i18n keys + its test).

The Cmd/Ctrl+/ predicate keyed off e.code==='Slash' + !e.shiftKey, which on
QWERTZ layouts (a) stole Ctrl/Cmd+- browser zoom-out (physical Slash there is
the minus/zoom key) and (b) missed the real shifted-'/' chord. Match e.key==='/'
instead — layout-correct on every keyboard. Tests updated to assert the physical
code isn't used and a layout-shifted '/' still matches.
