iOS fires visualViewport scroll events at 60fps during a pan with the
keyboard up. Routing those through React state and into the .chat-thread
translateY(--vv-offset-top) transform amplified the pan into a visible
judder + ~300px shift + body background exposure.
useMobileKeyboard now uses two listeners: a full update (resize +
focusin/focusout) that re-snapshots all metrics including offsetTop, and
a scroll-only update that updates only height/keyboardOpen. offsetTop
is therefore frozen between keyboard open/close events — the transform
correctly compensates for iOS's initial visualViewport shift on focus
without following pan-time movement.
Restores the translateY anchor (so the thread isn't off-screen on
first focus) while keeping the swipe-jitter fix.

After dismissing and re-bringing up the mobile keyboard, iOS could
leave window.scrollY > 0 and visualViewport.offsetTop > 0. With
useMobileScrollLock then pinning body{position:fixed} relative to that
drifted scroll, the message thread anchored above the visible viewport
and a large blank area appeared below it.
handleInputFocus now resets window scroll to (0,0) on mobile in a
zero-delay timeout — late enough that iOS finishes its own
scroll-into-view first, but before useMobileScrollLock observes the
drifted state.

Two mobile chat regressions addressed together:
1) ChatView send button: preventDefault now fires on pointerdown for
touch pointers, before iOS blurs the textarea. The previous
onMouseDown.preventDefault was too late on iOS (mousedown is
synthesized after touchend, by which point the keyboard has
already started dismissing). Click still runs the action so quick
taps remain reliable.
2) ExecutorStatusBar: hidden on mobile while keyboard is open,
mirroring MobileNavBar. The bar is position:fixed against the
layout viewport, which iOS leaves anchored below the keyboard;
during a swipe/pan it would slide over the messages list.

The imperative useLayoutEffect approach made mobile worse — first tap
flickered and didn't bring up the keyboard, while the original
swipe-overlap symptom remained. Restoring the previous React-state
flow until a better fix is identified. Removes the changeset that
shipped with the failed attempt.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The mobile composer/footer slid over the message list when the user
swiped with the keyboard up. Cause: --vv-height / --vv-offset-top were
routed through React state via useMobileKeyboard, so on iOS — which
fires visualViewport scroll/resize on the same frame as its keyboard
animation — the .chat-thread translation lagged by one paint, visible
as the composer momentarily floating over messages.
Now those two vars are written imperatively in a useLayoutEffect
directly to the .chat-thread DOM node on every visualViewport event,
mirroring the working pattern at QuickChatFAB.tsx:1032-1052 (which
already works correctly on mobile). Only --keyboard-overlap (a
structural open/close signal, not per-frame) still flows through
React state.

Re-add preventDefault on mousedown so the textarea doesn't blur when
the user taps send — keyboard stays up, no viewport reflow jumping
the input to the top of the screen. The action still runs on click
(which fires reliably from the iOS touch sequence even for quick
taps), so this preserves the previous fix's quick-tap reliability.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The mobile send button used pointerdown + touchstart with preventDefault
and a focus-preservation dance to keep the keyboard up while sending.
That path silently failed on quick taps on iOS — only a long press
registered. Switching to plain onClick (with touch-action: manipulation
to skip the click delay) fires reliably on tap. The soft keyboard may
dismiss on send now, which is a minor regression vs. the previous
intent but vastly preferable to silent failure.
QuickChat is unchanged because it already works on mobile.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The previous fix introduced a regression: handledMobileSendRef /
handledMobileActionRef was set in onPointerDown/onTouchStart but only
cleared in onClick. preventDefault() on pointer/touch events suppresses
the synthesized click on iOS Safari, so the ref stayed true forever
after the first tap — every subsequent tap (quick OR long press) hit
the new dedupe guard and silently bailed.
Now both handlers schedule a 500ms setTimeout to self-clear the ref
alongside their action. That covers the full pointerdown/touchstart/
click burst from one tap while still letting the next user tap go
through.
Applied to: ChatView send button, QuickChat send button, QuickChat
stop button.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The ChatView and QuickChat send/stop buttons each had both an
onPointerDown and an onTouchStart handler invoking the action. On a
quick mobile tap both fire, so handleSend / handleSendMessage /
stopStreaming ran twice in rapid succession. The second invocation
closed the first's SSE stream (streamRef.current.close()), the server
treated that as a cancel via beginGeneration, and the chat ended with
no output — exactly matching the reported "tap silently fails, long
press works" symptom (long press happened to suppress one of the two
events).
Both handlers now early-return when the existing handledMobile*Ref
flag is already set, so only the first event for a given tap fires the
action. The send button additionally gets touch-action: manipulation
(removes the click delay that lets the textarea blur win the race) and
an expanded invisible hit area via ::before so slightly-off taps don't
land on the surrounding textarea and dismiss the keyboard without
sending.

Backend
- chat.ts now routes both regular chat and QuickChat through
createResolvedAgentSession instead of branching to createFnAgent for
the no-runtime-hint case. This removes the divergent path where
pi-ai's cleanupSessionResources(sessionId) could tear down resources
the next generation depends on.
- sendMessage's finally only disposes the agent if it still owns the
activeGenerations slot. A newer generation that has pre-empted us
cleans up its own agent in its own finally — disposing here would
yank the underlying CLI process out from under it.
- __setCreateFnAgent test helper now mirrors its mock into the
createResolvedAgentSession slot so existing test setups still work
after the unification.
Frontend
- Extract createChatStreamHandlers (RAF coalescing, accumulators,
tool-call dedup, fallback handling) — useChat and useQuickChat were
duplicating ~85 LOC each. Both now compose the shared factory.
- Move shared chat types into chatTypes.ts. The hooks re-export them
for backward compatibility with existing consumers.
- Removed per-message Markdown/plain-text eye toggles. A single
thread-level toggle in the chat header now flips every assistant
bubble (including the streaming one) between rendered Markdown and
plain text.
- Model-only chats hide the per-message agent identity row entirely;
the model name is already in the thread header.
Tests
- Updated ChatView tests to reflect the new render-toggle contract
(single header toggle drives all bubbles) and the model-only avatar
suppression.

useMobileKeyboard now requires a focused input for keyboardOpen=true (both
the chrome-overlap and iOS-gap paths). The moment an input blurs, the hook
reports keyboardOpen=false instead of waiting hundreds of ms for iOS's
visualViewport dismissal animation to settle.
This makes App-level mobileKeyboardOpen flip false instantly on blur, so
MobileNavBar reappears and project-content regains nav-bar padding in the
same frame. The ChatView composer (and TodoModal/PlanningModeModal) snap
to their post-keyboard layout in one move instead of crawling down with
iOS's keyboard slide.
Replaces the per-component 450ms suppress hack in ChatView (also dropped
in this commit) which couldn't reach the parent layout's nav padding
state and produced "below tab bar then snap up" jitter.
Adds a regression test and updates four existing tests that assumed
"vv shrinks → keyboard up" without focus (focus is now required).

- Add useMobileScrollLock hook using position:fixed body lock (Bootstrap/
Headless UI/Stripe pattern) to prevent iOS Safari from shifting the
document and visualViewport when an input inside a fixed-position modal
is focused. Wire into 15 input-bearing modals plus ChatView, replacing
ChatView's inline body-overflow effect.
- Widen computeBuildVersion in vite.config.ts to hash the entire app/ tree
so the version-check poll actually notices rebuilds (FN-3333 follow-up;
previously only main.tsx and package.json were hashed).
- ChatView: on input blur, suppress keyboard-aware sizing for 450ms while
reserving mobile-nav-bar space, so the composer snaps to its final
height in one move instead of crawling down with iOS's keyboard slide
and then jumping again when the nav bar reappears.

Workflow-step REVISE retries, pause→todo handoffs, and the
context-overflow fresh-session requeue were all routing tasks back to
`todo` before returning to `in-progress`. The default reopen-to-todo
path reset every step to pending and rewrote PROMPT.md checkboxes, so
each retry restarted from step 0 even when earlier steps had already
been done — the symptom seen on FN-2978, where every workflow REVISE
or pause cycle wiped the task's progress.
- Add `preserveResumeState` to `TaskStore.moveTask`. When set, skip
`resetAllStepsToPending` + `resetPromptCheckboxes` and keep
`worktree` and `executionStartedAt` so the resumed run reattaches to
the same checkout. `status`, `error`, and `blockedBy` still clear.
- Use it on the workflow-rerun bounce, the three pause-graceful
handoffs, and the context-overflow requeue. The agent-terminated
pause path still discards (it nukes worktree+branch by design).
- Context-overflow requeue clears `sessionFile` synchronously in the
awaited `updateTask` immediately before `moveTask`, so the next
dispatch cannot reopen the saturated session via a stale pointer.
- `fn_task_update` no longer silently regresses `done`/`skipped` steps
to `in-progress`, no longer captures a stale rewind checkpoint when
it does, and tells the agent honestly when a regression is ignored.
- Mobile chat keyboard: ChatView/QuickChatFAB gate layout on the new
`keyboardOpen` flag so focused-input + viewport-shrink iOS cases
still adjust when the computed overlap is zero.
Tests:
- New `preserveResumeState` coverage in store.test.ts; updated
workflow-rerun + pause-graceful assertions in executor.test.ts.
- Restructured the previously-flaky "routes exhausted prompt-mode
workflow hard failures" test to drive the bounce inline; passes in
isolation and in the wider workflow/pause/context sweep (59/59).
- Added regression tests in ChatView.test.tsx and QuickChatFAB.test.tsx
for the iOS last-resort `keyboardOpen=true, keyboardOverlap=0` case.

- Add a shared useMobileKeyboard hook that tracks visualViewport overlap on mobile browsers
- Apply keyboard overlap CSS variables to QuickChatFAB so fullscreen mobile panels resize above the virtual keyboard
- Apply the same keyboard-aware sizing to ChatView mobile thread layout and auto-scroll messages when keyboard opens
- Expand ChatView, QuickChatFAB, and hook test coverage for mobile keyboard detection and viewport-resize behavior
- Track plain-text render mode per assistant message (including streaming output) in ChatView state
- Add inline mobile-only Eye/EyeOff toggle buttons on assistant bubbles to switch markdown vs plain text per message
- Hide the header markdown/plain toggle on mobile and polish inline toggle sizing, focus, and hover styles in ChatView.css
- Extend ChatView tests with mobile viewport coverage for toggle rendering, per-message isolation, round-trip toggling, and mobile CSS contract checks
- ChatView mobile: add @media (max-width: 768px) so the session-list
sidebar goes full-width and the thread is hidden when the sidebar
is visible (and vice-versa). The component already had the state,
back-button (ChevronLeft), and visibility toggling — only the CSS
was missing.
- TaskComments compose/edit textareas now use var(--surface) for
background. The base .spec-editor-feedback uses var(--bg), which
in light theme resolves to #ffffff — the same as the task detail
modal's --card panel — making the comment box invisible.
- ChatView CSS is now imported eagerly from App.tsx so it bundles
into the main CSS file. Previously the lazy ChatView JS chunk
loaded its CSS via an async <link> tag, producing a brief flash
of unstyled chat UI on first render.

Split app/styles.css from ~40k lines down to ~4.5k. Created 56 co-located
component CSS files in app/components/, each imported by its owning .tsx.
The remainder of styles.css holds genuinely global rules (design tokens,
.btn/.card/.modal/.form-input primitives, cross-component @media overrides).
- Lazy-load 13 heavy views (AgentsView, RoadmapsView, NodesView, etc.) via
React.lazy + Suspense; prefetch all chunks on idle so first navigation is
instant. Initial JS bundle: 1.58 MB → 1.16 MB (-26%). Initial CSS bundle:
635 kB → 471 kB (-26%); the rest splits into 13 per-view chunks.
- Add app/test/cssFixture.ts exposing loadAllAppCss() + loadAllAppCssBaseOnly()
so CSS regression tests load the full per-component bundle (mirroring Vite
source order). Migrate 30+ tests off direct readFileSync('../styles.css').
- Enable test.css: { include: [/.+/] } in vitest.config.ts so component CSS
imports actually inject styles in jsdom (fixes getComputedStyle assertions).
- Add ESLint rule (no-restricted-syntax) banning direct styles.css reads in
dashboard test files; points at loadAllAppCss() instead.
- Restore lost utility classes (.text-muted, .text-secondary, .text-dim,
.form-input) and rescue dropped chat tool-call rules into QuickChatFAB.css.
- Mobile fixes along the way: scroll containment for view containers
(min-height:0 + -webkit-overflow-scrolling), QuickChatFAB full-screen on
mobile (with safe-area-inset for iOS home bar), AgentsView single-row
header layout, ActivityLogModal close button on right, model-combobox
z-index above the mobile quick-chat panel.
- Bug fix: SkillsView toggle was display:none which hid the input from the
accessibility tree; replaced with the visually-hidden pattern so screen
readers + getByRole still find the checkbox.
- Bug fix: standalone Delete button in TaskDetailModal for triage-column
tasks (Actions dropdown is hidden in triage state, so previously no way
to delete a freshly-created task without status change first).
