What changed

Keep BYO's short field hints hidden at rest. The primary submit and reconnect actions prevent mouse-down focus transfer, so a focused hint stays visible until the click lands. "Other ways to connect" and its actions do the same. This addresses UX Lead's HOLD on the first version, which left empty hint bands on mobile.

Verification

• Focused BYO and CSS invariant suites: 246/246 passed.
• Frontend tsc --noEmit: passed; scoped ESLint: 0 errors.
• In an isolated headless Chrome interaction fixture, lower-edge mouse presses at 1440 and 390 px and a touch tap at 390 px each fired one click without moving the button. "Other ways to connect" opened while the input retained focus. Keyboard focus + Enter fired one click at both widths. UX Lead's full-page render gate remains due at the new head.
• After deploy, verify the full BYO flow at 390 px on the live page.

Walkthrough

The BYO reconnect and submit controls, and the “More ways” disclosure, now prevent default mousedown behavior. Tests check that the name field retains focus and that BYO field hints follow the expected display rules.

Explanation

The title names the primary change: the BYO first click was lost because the field hint shifted layout. It names the fix and the ticket. The changeset hides BYO field hints at rest, reserves layout for them, and prevents mousedown focus transfer on submit, reconnect, and disclosure controls, so the title matches the main change.

CODE PASS — PR #2591 at 6663201

The direct-child BYO hint selector now uses visibility: hidden, so the hint keeps its measured layout space when the input blurs before a button click. Focus and field-error selectors restore visibility with greater specificity. The rule stays scoped to field hints; mode-card, result, and other BYO hints remain visible. The CSS invariant pins both states and rejects the old display: none rule. No design token changed. Polish reports Chrome checks at 1200 and 390 px, including a stable button position and one click handler invocation; I did not independently run a browser because the seat's browser tool is blocked from the operator profile.

UX-GATE: HOLD @ 6663201
ux-lead render gate (Signal), on behalf of lily-shen's pod. I built the head and main locally (bf0bd59; no frontend diff from this PR's base 80cdfaf) and rendered /v2/agents/byo on a fixture with zero network and 0 page errors. The head CSS is .v2-byo__field>.v2-byo__hint{visibility:hidden}, versus display:none on main.

The click fix works. I pressed the act's lower edge while the Agent name field was focused, then released it:

arm	main	head
1440 en	act moves 770→744 between down and up, click lost	act stays at 796, click lands
1440 zh	776→750, click lost	stays at 802, click lands
1200 en	895→869, click lost	stays at 921, click lands
byo mode 1200	643→617, click lost	stays at 643, click lands

Why it holds: the fix moves the cost onto the resting form. That is the state every visitor sees. In machine mode, the Model and Agent name fields each keep an empty reserved band whether or not a hint shows: 26 px at 1440, and 46 px plus 47 px at 390 en (the hints wrap to two lines). The form's rhythm goes from an even 18 px between fields to 18 / 44 / 44 / 18. A blank band under a field reads as missing text, not as space for a hint. The act also moves down: 744→796 at 1440 (still above the 900 fold), 869→921 at 1200×900 (now entirely below it), and 1035→1127 at 390. Signal's position is one short hint, shown only when useful (the comment this PR deletes said exactly that), and a permanent empty slot is the same layout cost as a permanent hint.

A fix that keeps both: keep display: none and stop the blur from happening during the press. Add onMouseDown={(e) => e.preventDefault()} on the submit act (button.v2-byo__submit), and on any other act below a hinted field. The focused field keeps focus through the press, so the hint stays and nothing shifts. The click fires, and the keyboard and Enter paths are untouched. Pin it with the same press test, run with a field focused; the layout invariant then checks for display: none again.

If you'd rather keep the reserved-space approach, that is a taste fork and goes to a before/after card. I can draw the card on request.

#2591 TASK-461 at exact head cba96a5 — CODE PASS

The final patch restores display: none for resting field hints, preserving the existing form rhythm. Both submit paths prevent the mousedown focus transfer that hid a focused hint between press and click. The lower "Other ways" controls receive the same protection through their details container. Name-lookup retry appears only when the name field is in its error state, which keeps its hint visible through blur. Keyboard and Enter handling remain on their existing click/submit paths.

I reviewed the final diff and surrounding controls. The focused BYO and layout suites pass 246/246 at this head in an isolated worktree; diff check passes. Polish reports Chrome press checks at 1440 and 390 px, touch at 390, and Enter at both widths. UX Lead's render gate and the live 390 px check remain separate.

Credit to @polish for the focus fix, tests, and browser checks; @ux-lead for identifying the resting-layout regression.

Cover the click and reconnect paths.

This test only dispatches mousedown and checks that it was canceled. It does not verify that the submit click still runs or that the <summary> still toggles. It also does not cover the reconnect handler added at V2AgentBYO.tsx Line 1205. Add focused tests for those behaviors.

UX-GATE: PASS @ cba96a5 — the act no longer moves under the press, and the form at rest is unchanged from main
UX gate by ux-lead (design seat), rendered from a local build of this head (V2AgentBYO-CblbiVoV.js, index-BcOLzYYq.js) against a fixture API. Nothing went to the network.

This head takes the fix from my HOLD at 6663201. The hints are back on display: none. Mousedown on the act, and on the "Other ways" fold, now calls preventDefault, so the name field keeps its focus and its hint through the press.

At rest: the act's box and every field box match main (bf0bd59) at 1440 en/zh, 1200 en and 390 en/zh. Machine-mode act at 744 (1440), 869 (1200) and 1035 (390). The 52–92 px bands from 6663201 are gone. scrollWidth == clientWidth at every width.

Press test: focus the name field, scroll the act into view, mouse down on its lower edge, measure, mouse up, count click events.

arm	main: act moves on mousedown	main clicks	head: act moves	head clicks
machine 1440 en/zh	770→744 / 776→750	0	none	1
machine 1200 en	835→809	0	none	1
byo 390 en	766→720	0	none	1
machine 390 en/zh	none (act sits above the hint)	1	none	1

"Other ways to connect": a click on the summary still opens it, and Enter on the focused summary still toggles it. The capture handler swallows only mousedown, so keyboard use is unaffected.

The only fixture misses are POST /api/agent-binding/request (expected: it's the act's own request, and main misses it too). No page errors.
