The phone tier stopped at innerWidth < 430 and @media (max-width: 430px), so every current large phone landed in the tablet layout: the 430pt iPhone 14 Pro Max, 15 Plus, 15 Pro Max and 16 Plus, the 440pt iPhone 16 Pro Max and 17 Pro Max, Pixel 6 Pro, 7 Pro and OnePlus 12 Pro, the 448pt Pixel 8 Pro and 9 Pro XL, and the Galaxy Z Fold 5 cover screen at 460. On those devices the header icon row replaced the session pill, the toolbar kept the desktop Run Shell button instead of Enter and the mic, the keyboard accessory bar could never become visible because its .visible rule lives inside the phone block, and the toolbar jumped to the top of the page when the keyboard opened.
The new cutoff is 600, the line test/mobile/devices.ts already draws between large phones (430-599) and small tablets (600-767). No physical device sits between 480 and 600, but a phone zoomed out one or two steps in Safari does: a 440pt iPhone at 85% or 75% page zoom reports 518px or 587px and still needs the phone controls, which a 480 cutoff would have taken away. The phone block is max-width: 599px and the tablet block starts at min-width: 600px, so a 600px device is a tablet in CSS and in getDeviceType() alike instead of straddling the boundary the way 430pt phones did.
The number changes everywhere it is encoded: JS, CSS, comments, CLAUDE.md, the CI tests that pin the phone block, and the test:mobile helpers. Measurement history that names 430px stays as written.
The brand "C" got a 44px-wide hit box in the previous commit but was capped at
36px tall by the bar it sits in. The phone header is now 44px, so the one
control that gets you back to the home screen is square at the platform
minimum, and every other header control gains the same 8px.
Redefined as --header-height inside the phone media query rather than as a
literal, so the panels positioned off that token (file browser, project
insights, plan overlays) follow the bar instead of drifting 8px underneath it;
.app's top offset is derived from it for the same reason. The header also stops
top-aligning its children on phones: that read as centred in a 36px bar whose
contents were ~31px, and leaves a visible gap under everything at 44px.
Costs 8px of terminal height on a phone.
Verified on a real isolated instance at 390px: header 44px, button 44x44
spanning the bar, a touch tap at (4,41) - inside the new area, outside the old
one - reaches the home screen, tabs centred, and content still clears the fixed
header. Tablet (48px) and desktop are untouched.

The welcome overlay centers ~560px of content in a ~1400px window, so both
gutters are dead space. The left one now carries the open tabs as a vertical
list (home-sessions.js): one row per live session plus saved web tabs, in TAB
order rather than by urgency, because the row badges are the Alt+1..9 indices.
Clicking a row enters that session.
Working state is deliberately the phone's, exactly: a pulsing green dot ringed
by the same tab-load-spin the tab strip uses while a tab loads, now with a green
halo added on both surfaces so "working" reads identically wherever you see it.
The column is position:absolute so the centered content never moves, which is
why it needs a width gate in two places (HOME_SESSIONS_MIN_WIDTH = 1180 in JS,
a max-width: 1179px media query as the backstop for a resize that outruns the
matchMedia listener). A test pins the two equal. State classification is reused
from mobile-overview.js rather than re-derived, so the two home screens cannot
disagree about what counts as needing you.
Phones keep the mobile overview, and their brand "C" was a 0.85rem inline span,
roughly a 12x13px target on the one control that gets you back to that screen.
It is now a 44px-wide button filling the full header height, with the glyph
scaled to match. 44 is horizontal only: the phone header is pinned to 36px and
clips overflow, so a true 44x44 would mean taking height off the terminal.
Verified end to end against a real isolated instance (own tmux socket + data
dir): 18 browser checks covering render, live update through the tab renderer,
the working dot's animation/glow/ring, row click, the narrow-window gate, the
phone fallback, and a real touch tap on the far corner of the new hit box.

- Hide the new btn-session-manager header button on phones: add it to the
@media (max-width: 430px) display:none block in mobile.css (next to
.btn-away-digest) and to KNOWN_PHONE_HIDDEN in the mobile-header policy
test, closing the recurring phone-header-leak regression that was PR
#153's red CI job.
- Put the session-manager header button on its own line in index.html
(was crammed onto the away-digest line).
- app.js: drop session:updated from the unified-list SSE refresh trigger —
it is batch-broadcast ~every 500ms per active session and would turn an
open modal / visible welcome list into a sustained ~1 Hz full projects
rescan loop; created/deleted (structural changes) are sufficient.
- terminal-ui.js _fetchUnifiedSessions: check the ApiResponse envelope and
throw on failure so a 5xx surfaces via the caller's catch instead of
rendering an empty history.
- terminal-ui.js _openSessionRowMenu: on re-entry, invoke the previous
menu's close fn (stored as _openRowMenuClose) so its document/window
listeners are detached rather than leaked; use claudeSessionId ||
sessionId in the 'Resume session' menu item to match the main-row and
Session Manager resume routing.

The COD-39 attachments button was hard-visible in the header — first on
mobile, then (after the mobile-only hide) still on desktop. Make it a
proper opt-in App Settings → Display toggle ("Attachments Button"),
default OFF everywhere, mirroring the Response Viewer button:
- index.html: button ships with the `btn-attachments-history--hidden`
marker; new settings checkbox #appSettingsShowAttachmentsButton.
- styles.css: base `display:inline-flex !important` + a more-specific
`--hidden` rule (same pattern as the response viewer).
- settings-ui.js: load/save/getDefaultSettings(false) + a live toggle in
applyHeaderVisibilitySettings. Per-device and NON-leaking — added to
displayKeys AND stripped from the server payload, so enabling it on
desktop never makes it appear on mobile (or any other device). No
server-side render step (purely client display, like the eye button).
- mobile.css: dropped the now-redundant phone-only hide — the opt-in
marker hides it everywhere by default; the per-device toggle governs
both desktop and phone.
Tests updated: the CI static guard drops btn-attachments-history from the
phone-hidden lock (it's opt-in now, excluded from the default-visible
enumeration — the guard still gates any NEW default-visible button); the
real-browser E2E now asserts default-hidden on a desktop-class viewport
and visible after enabling the setting.
Verified on a real desktop browser: hidden by default, the settings
toggle exists, enabling it shows the button. tsc + frontend-syntax +
prettier + public-asset checks + both test suites green.

The COD-39 attachment-history header button was visible on the cramped
phone header. Hide it on phones alongside the settings gear and lifecycle
log (the mobile header is intentionally minimal — those controls live in
the toolbar). One-line addition to the existing @media (max-width: 430px)
display:none block in mobile.css.
This is the second time a header control leaked onto mobile (the
plan-usage chip was the first), so add two regression guards:
- test/mobile-header-buttons-policy.test.ts — a pure static analysis of
index.html + mobile.css (no browser), so it runs in the normal CI sweep
(the test/mobile/** Playwright suite is EXCLUDED from CI and never gated
this). It enumerates every default-visible header button and fails when
one has no phone-visibility decision — either a mobile.css hide rule or
an explicit MOBILE_VISIBLE_ALLOWLIST entry. A new header button now
forces that decision. Verified it fails on the pre-fix state and passes
after.
- test/mobile/header-buttons.test.ts — real-browser E2E in the mobile
suite: asserts the attachments/settings/lifecycle buttons are hidden on
an emulated iPhone 14 Pro and the attachments button is visible on a
desktop-class tablet.
tsc + lint + prettier + both new tests green. Only CSS + tests changed.
