Phase 0 of the mobile user-flow alignment

MobileChat reuses the fixed hooks (useChatSend/useChatSocket), so the 524-as-still-processing + dedup fixes already reached mobile. But three ChatTab behaviors lived in the desktop render and never made it to mobile:

1. Multi-send — the send handler still gated on sending, so mobile users couldn't fire a follow-up while the agent worked (the hook supports it; #2726). Removed the || sending block.
2. Stale "Failed to send" banner — never cleared on mobile. Now clears when a reply lands / send completes (#2736) and the instant the agent is thinking (#2745).
3. No thinking indicator — added ●●● Ns with an elapsed timer keyed on sending || currentTask (#2720) so a long turn doesn't look stalled.

Tests / CI

+2 MobileChat tests (indicator shows on currentTask, hidden when idle); full mobile suite green (249). Runs in the blocking canvas vitest gate.

First step of the mobile-flow optimization plan; bigger phases (Tasks/Approvals inbox, agent tree) await CTO steer on scope.

fix(mobile-chat): parity with desktop ChatTab — multi-send, thinking indicator, banner-clear (core#2697) ... 04eac0f01f

MobileChat reuses the fixed hooks (useChatSend/useChatSocket), so the 524-as-
still-processing + dedup fixes already reached mobile — but three ChatTab
behaviors lived in the desktop render and were missing on mobile:

1. Multi-send: the send handler still gated on `sending`, so mobile users
   couldn't fire a follow-up while the agent worked (hook supports it; #2726).
   Removed the `|| sending` block.
2. Stale "Failed to send" banner: never cleared on mobile. Now cleared when a
   reply lands / send completes (#2736) and the instant the agent is `thinking`
   (#2745) — mirrors ChatTab.
3. No thinking indicator: added "●●● Ns" with an elapsed timer keyed on
   `sending || currentTask` (#2720) so a long turn doesn't look stalled.

Tests: +2 (indicator shows on currentTask, hidden when idle); full mobile
suite green (249).

REQUEST_CHANGES on head 04eac0f.

Blocking correctness issue: the PR removes the sending guard from the send() handler, but the primary mobile send button is still disabled while sending:

disabled={(!draft.trim() && pendingFiles.length === 0) || !reachable || sending || uploading}

That means tap-based mobile users still cannot multi-send during an in-flight turn, which is one of the three explicit desktop-parity behaviors this PR is meant to ship. Only the Enter-key path can reach send() while sending; the main mobile UI path remains blocked. The cursor/background logic around the button also still keys on !sending, so it visually advertises the old behavior.

Please remove the stale sending gating from the send button disabled/style state to match the handler, and add/adjust a MobileChat test that proves a second tap-send is possible while sending is true. The thinking-indicator tests are useful, but they do not cover the multi-send parity behavior.

REQUEST_CHANGES on head 04eac0f01f5f878340e4cb90a05e28788122d290.

Findings:

1. Mobile multi-send is still blocked on the primary tap path. MobileChat.send() correctly removes the sending guard at canvas/src/components/mobile/MobileChat.tsx:357-369, but the Send button remains disabled while sending is true at MobileChat.tsx:834-838, and its cursor/background/color state also keys on !sending at :845-853. On mobile, the send button is the primary follow-up-send affordance; after the first message starts, the button disables and a second distinct message cannot be sent by tapping until the prior turn completes. That is not desktop ChatTab parity, where the Send button is not disabled by sending (ChatTab.tsx:895-898), and it does not satisfy the PR's multi-send claim. The attach button also still gates on sending at MobileChat.tsx:767-785, which is another mobile/desktop parity mismatch for composing a follow-up while the agent is working.

2. The new tests do not cover the core multi-send behavior or the #2759 overlap. The added tests at canvas/src/components/mobile/__tests__/MobileChat.test.tsx:649-661 only assert thinking indicator visibility from currentTask; there is no mobile test that sends one message, leaves useChatSend.sending true, edits a second draft, and proves the mobile Send button remains enabled and dispatches a second POST. There is also no test proving the stale-banner clear behavior added in MobileChat.tsx:243-262. Given #2759 is currently RC'd for shared useChatSend concurrent-send token lifecycle, #2762 should at minimum avoid adding untested mobile multi-send assumptions and should compose with the pending hook fix.

I do not see #2762 directly reintroducing the #2759 token leak because it does not modify useChatSend, but enabling mobile multi-send while the mobile UI still blocks on sending and while no mobile race coverage exists is a correctness gap. Please remove the sending gate from the mobile send affordance(s) where desktop parity requires it, add a mobile multi-send regression test for the tap workflow, and add/confirm coverage for the banner-clear path. I did not approve; Canvas CI was still pending when I inspected, but these are blocking issues independent of CI.

fix(mobile-chat): Send button must not disable while sending (CR2 #2762)

core-devops added 1 commit 2026-06-13 19:37:04 +00:00

fix(mobile-chat): Send button must not disable while sending (CR2 #2762) ... 323a8f39c4

The send() handler dropped the `sending` guard but the tap button — mobile's
PRIMARY send affordance — still had `disabled={... || sending ...}` + cursor/
bg/color keyed on `!sending`, so a follow-up couldn't be tapped mid-turn.
Remove `sending` from the button's disabled + styling to match the handler.
Test: button stays enabled during an in-flight (hanging) send.

APPROVED on head 323a8f39.

Re-review after CR2 #11456: the blocking tap-path issue is fixed. The mobile Send button no longer disables or styles itself as unavailable while sending; it now gates on empty input, reachability, and uploading, matching the updated send() handler and the desktop multi-send behavior. The added regression drives a hanging send and verifies the primary mobile tap affordance stays enabled for a follow-up message.

5-axis:

• Correctness: restores the three requested desktop parity behaviors on mobile: multi-send, stale error clearing on reply/send-complete/thinking, and visible thinking elapsed state.
• Robustness: timer effect cleans up on thinking changes; error clearing is scoped to reachability-proving states; tap-path multi-send is now covered.
• Security: UI-only chat behavior change, no auth/secret surface.
• Performance: one 1s interval only while thinking; cleared on stop/unmount.
• Readability/tests: implementation is narrow and comments explain parity intent; mobile suite regression covers the prior miss.

Verified current head is open/mergeable and CI/all-required is green. /sop-ack

Post-merge audit on merged head 323a8f39 (review endpoint is closed because the PR merged while I was re-reviewing).

My prior RC is only partially resolved. The mobile Send tap path is fixed: send() and the Send button no longer gate on sending, and the new tap-path test covers that part.

Residual issues I would still want followed up:

1. canvas/src/components/mobile/MobileChat.tsx:770 still disables Attach while sending is true, with matching disabled cursor/opacity at lines 778 and 785. That leaves the attach affordance blocked during an in-flight turn, so the parity gap I flagged is still present for follow-up attachment sends.

2. I do not see a mobile regression test for the banner-clear path. The implementation clears stale send errors from onAgentMessage, onSendComplete, and thinking, but canvas/src/components/mobile/__tests__/MobileChat.test.tsx only adds thinking indicator coverage and the Send-button tap multi-send test. Please add a test that proves a stale send-error banner clears on the mobile callback path changed here.

This is a post-merge follow-up note, not a formal blocking review, because the PR is already merged.
