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.
