Leo: "let's get rid of the blinking dot asap", "we need to guarantee the breathing dot doesnt come back".

#23776 (merged) made the spinner the default working look again, and #23870 (open, owner alive) deletes the native and web breathing working look. Both leave alone the other web status dots that still breathe at default settings. #23870's body lists them as "a different feature". This PR makes those dots still and adds a guard over every shipped web stylesheet, so a breathing or blinking dot can't come back under any class name.

Still now (they breathed at default settings on base)

• Floating chat: the header's streaming status dot (.acpmux-floating-status[data-status=streaming], acpmux-floating-breathe, webviews/src/agent-session/acpmux/styles.css:543). It is a still accent dot now.
• Chief dock: the card's streaming status icon (.acpmux-chief-dock-status[data-status=streaming], same keyframes, styles.css:633). It is a still accent colour now.
• Home ledger: the working state's dot and the avatar's working mark (.lg-state.working::before, .lg-state-mark.working), and a running run's mark (.lg-run-mark.running). These used lg-pulse in webviews/src/pages/home-channels/ledger.css:303-313, 1252-1256.
• Settings > Accounts: the cmux account dot while a sign-in runs (.accounts-status[data-busy] .accounts-dot, accounts-busy, webviews/src/pages/settings/styles.css:926-935). The status words beside it ("Signing in…") still say it is busy, and aria-busy is unchanged.

The Static status indicators triangle for a floating chat that needs you is unchanged. The unused acpmux-floating-breathe keyframes are deleted, along with the Static and Reduce Motion rules that only stopped them. That includes the Chief dock status's dead animation:none in its Reduce Motion block.

The Inspector's running subagent avatars carry their status dot (.cv-subagent-avatar__dot, subagents.css:87-98). They breathed on this PR's original base (acpmux-chat-inspector-breathe), and this PR's second commit deleted that. Since then, #23995 (merged) replaced it on base with RUNNING-WAVE (ui/wave.css, cmux-wave): one opacity shimmer that sweeps across the running avatars. Static, Reduce Motion and the motion gate stop it. That is a newer, deliberate decision by another lane, so the guard lists it explicitly rather than this PR undoing it.

Guard

webviews/test/no-breathing-dots.test.ts is a static read, with no browser. It parses every stylesheet under webviews/src, except the never-loaded prototypes/. It reads:

• rules nested in @media and in CSS nesting;
• the animation shorthand and the animation-name / animation-iteration-count longhands, with or without -webkit-, with infinite in any case;
• a repeat count (or a name-less infinite shorthand) set in a different rule, which counts for every rule whose subject has the same class.

It lists every animation that repeats forever and whose keyframes fade (opacity), blink (visibility) or pulse (scale).

Each loop it finds must be on an allowlist (file, keyframes, selector) that gives the reason it is not a status dot. Those reasons cover the mic's start wait, #23995's running wave, the Apps loading skeleton, the Cloud illustration, Home's "writing" word and the music level bars. Jump to latest's dots are listed under Left alone. The test also fails when an allowlist entry matches nothing, so the list can't quietly cover a new loop. Entries that another open PR removes or adds carry goneWith and may match nothing.

A synthetic stylesheet proves it catches a dot under any name, inside a media query, nested, with -webkit-, written INFINITE, by longhands, and with its repeat count in another rule. It also proves the guard ignores a spinner's rotation and a one-shot fade.

• Red on base (test commit 6feda44f5fc1d8da8ae5de2612519ac4cccd1900, before the fix): 3 pass, 1 fail. no stylesheet fades, blinks or pulses a dot forever lists the 5 rules above.
• Green on head 6cf03d272fac71bbe27010f5860f64edf223008d (feat-cmux-next brought in by a merge commit): 4 pass.
• Green on feat-cmux-next + fix(agent status): keep spinner defaults and preserve dot options #23870's head 990280666b + this head, combined: 4 pass. static-status-loops.test.ts passes there too.
• Command (huge-blue, from webviews/): bun test test/no-breathing-dots.test.ts

Also green on head:

• CMUX_BROWSER_TESTS=1 bun test test/static-status-loops.test.ts test/running-wave-loops.test.ts: 11 pass.
• bun test test/chat-inspector.test.tsx test/floating-chat.test.tsx src/pages/settings/accounts.test.tsx: 25 pass.
• cmux-ci compile-check --ref 6cf03d272fac71bbe27010f5860f64edf223008d --app: passed (job 39abaa6c7ff32ca85d29b332).

Left alone (reported to the lane, not changed here)

• The breathing working look itself (.cv-spinner[data-working] with cmux-breathe): fix(agent status): keep spinner defaults and preserve dot options #23870 deletes it. The allowlist marks that entry and the Apps skeleton's current cmux-breathe entry with goneWith: #23870. It also lists ahead of time the Apps skeleton's new name from fix(agent status): keep spinner defaults and preserve dot options #23870 (cmux-skeleton-pulse). Either PR can land first.
• Jump to latest's three working dots (acpmux-jump-latest-dot, cmux NEXT: Jump to latest morphs into pulsing accent dots while the agent works #21800) still pulse while the agent works. Static and Reduce Motion stop them. Making them still at default is a product call for that surface's lane, so here they are an explicit allowlist entry.
• cmux NEXT Inspector: running subagents shimmer in one wave instead of pulsing out of step #23995's running wave on the Inspector's subagent avatars (see above) is allowlisted. Whether a shimmer may run on an avatar that carries a status dot is for that lane and Leo to decide.

Observed / Not run

• Observed: the focused runs above on huge-blue, and vp fmt / vp check on the changed files.
• Not run: the app itself.

No capture: webview-only change; the visible difference is motion, which a still gallery frame can't show.

Changelog

• Fixed: The floating chat's and Chief dock's working dot, the Home ledger's working marks and the Settings account dot no longer fade in and out.

Review (codex gpt-6.1-sol): SHIP at 6cf03d2

No blocking findings.

Non-blocking finding: no-breathing-dots.test.ts is a lexical guard and does not resolve CSS variables used as animation names or repeat counts, nor animation declarations applied through selectors without classes. A future dot written through those forms could evade this check even though the current 111 shipped stylesheets are covered and all eight detected loops match the allowlist.

Checked the exact merge-base diff and whole changed files, enumerated all shipped webview CSS from the fetched commit, exercised the guard’s synthetic cases and current allowlist, and did not build the macOS app or run native suites.

Review (codex gpt-6.1-sol): SHIP at d9c3bf9

No blocking findings.

Non-blocking findings: none.

Checked the merge result against both parents, verified the delta since 6cf03d2 is only the clean base merge plus the intended four-file change, audited the status-dot CSS and stylesheet guard, and ran the focused no-breathing-dots Bun test from an archived PR tree.
