17ee59ccc5 feat(editor): standard Mermaid viewer with pan/zoom, exports and a real dialog (MUL-4908) (#5564)
* feat(editor): standard Mermaid viewer with pan/zoom, exports and a real dialog (MUL-4908)

Mermaid's fullscreen view was a bespoke lightbox: no visible close button, no
canvas interaction, and a toolbar that scrolled away with wide diagrams. Escape
also stopped working once the iframe took focus, which is why it read as
"impossible to close".

Replace it with a viewer built on the shared Dialog, so it inherits the
backdrop, focus trap, scroll lock, focus restore and Escape handling that HTML
preview already had.

The diagram stays in an `sandbox=""` iframe — isolation is not relaxed to buy
interactivity. Instead the iframe is `pointer-events: none` and pan/zoom is
applied from the host document as a transform on its wrapper. That inversion is
also what keeps Escape working: the iframe can never take focus.

- Viewer: fit-on-open, drag pan, wheel/pinch/keyboard zoom (25%-400%) anchored
  at the pointer, Fit / 100% / Reset, and a header toolbar that cannot scroll
  away. Panning is clamped so the canvas can never be lost.
- Export: `.mmd`, `.svg` and `.png`. Requires `htmlLabels: false` — browsers do
  not rasterize Mermaid's default HTML-in-foreignObject labels through an
  `<img>`; verified in Chromium that they paint zero pixels AND taint the
  canvas, so PNG export silently produced nothing.
- Inline: toolbar lifted out of the scroll container, natural-size rendering
  (small diagrams centered, wide ones scroll at a readable size with edge
  fades), copy source, and a parser message on the error fallback.
- Theme switches no longer close the viewer or discard zoom/position; the
  previous diagram stays on screen until its replacement is ready.

* fix(editor): stop Mermaid drags selecting text and misfiring the viewer (MUL-4908)

Two gesture defects on the inline diagram, reported by Naiyuan.

1. Dragging a diagram started a native text selection. The iframe is a replaced
   element, so the whole diagram box got painted with the selection highlight
   and the drag ran on into the surrounding comment text. Fixed with
   `user-select: none` on the inline scroller and the viewer canvas.

   Deliberately NOT by preventDefault-ing pointerdown: verified in Chromium that
   it also drops the default focus, which silently kills the viewer's keyboard
   controls (+/-, 0, arrows).

2. Any drag ended in a `click`, so trying to look along a wide diagram opened
   the viewer on top of the user. The inline diagram had no drag handling at
   all — only `onClick`. Suppressing the selection alone would have made this
   fire more reliably, not less, so both had to land together.

   Past a 5px threshold the gesture is a drag for good: releasing no longer
   taps, and a horizontal drag pans the scroller instead. This holds even when
   the diagram has no room to scroll, so an unscrollable diagram cannot open on
   release either. A still click, a sub-threshold jitter, and the expand button
   all still open the viewer.

Touch is left alone — it already pans natively and its vertical drags belong to
the page; the browser announces its takeover with pointercancel. Mouse and pen
have no native drag-to-scroll and are panned here.

Verified in Chromium: still click opens; a 150px drag pans and does not open; a
drag on an unscrollable diagram does not open; 3px jitter still opens; and no
gesture selects text.

ea03912baf perf(desktop,issues): single-router tab sessions (MUL-4741 Phase 2) + trace-driven surface mount/render overhaul (MUL-4474/4750 reland) (#5403)
* Reapply "perf(issues): virtualize inbox/list/board/swimlane (MUL-4474, 方案2) (#…" (#5395)

This reverts commit c10bfa8f56.

* fix(issues): seed virtualized lists so route-return doesn't flash blank (MUL-4750)

The relanded MUL-4474 virtualization flashed an empty card area (group /
column headers present, rows blank) when returning to /issues or crossing
inbox<->issues. Two stacked blank windows caused it:

1. The scroll element reaches Virtuoso via a callback ref that lands in
   state, so the first render after a remount has customScrollParent === null
   and the code rendered nothing.
2. Even once mounted, Virtuoso renders 0 rows until its post-paint
   ResizeObserver measures the viewport.

Fix both, four surfaces (list / board / swimlane / inbox):

- New shared <VirtuosoSeed> renders a bounded slice of the real rows while the
  scroll parent is still null, reusing each caller's own itemContent /
  computeItemKey so a seeded row is identical to its virtualized counterpart.
- Pass initialItemCount={Math.min(len, SEED)} so the measurement frame keeps
  those rows instead of collapsing to empty.

SEED is capped at 30 and floored by Math.min, so small workspaces
(hasMore=false) and short columns never over-mount — the path that crashed on
real Desktop before. restoreStateFrom (tab-switch Activity restore) is
intentionally out of scope for this round.

Verified: @multica/views tsc --noEmit, eslint, and full vitest (1936 tests)
pass. Real-Desktop route-return / DnD / keyboard / scroll-position regression
pass still owed on device.

* perf(issues): defer per-card popup mounting, share one context menu per surface

Tab-switching to a board froze the main thread for seconds: every card
eagerly mounted ~6 popup roots (context menu, pickers, hover cards) plus
per-card query subscriptions, multiplied by seed x columns x remount.

- DeferredPopup: pickers render a pixel-identical static trigger and mount
  the real popover on first pointerenter/keydown (Base UI opens on click,
  so the warm mount always wins the race)
- AssigneePicker/PriorityPicker/DateOnlyPicker defer when uncontrolled;
  AssigneePicker's members/agents/squads/frequency subscriptions now only
  start on interaction
- IssueActionsContextMenu: one controlled ContextMenu per surface anchored
  at the cursor via a virtual anchor; items delegate (issue, position) up.
  Known debt: iOS Safari long-press no longer opens it
- ActorAvatar hover cards warm-mount on pointerenter with a manual
  first-dwell timer matching Base UI's OPEN_DELAY

* fix(issues): stabilize board column scrollbar across mounts

Column scrollbars redrew visibly on every surface mount (route switches,
first open): the seed frame's scroll height covered only the seeded cards,
then Virtuoso spaced out the full count.

- VirtuosoSeed: optional estimatedItemHeight renders a trailing spacer so
  the seed frame's scroll height already approximates the full list
- Board columns: seed capped at 10 (one column viewport of ~110px cards,
  not the 36px-row-sized generic 30) and the same estimate feeds Virtuoso's
  defaultItemHeight so both phases agree until real measurements land
- Columns at <=30 cards skip virtualization entirely and render plainly
  (same itemContent), making their scroll height browser-measured truth in
  every scenario -- the per-column split Linear ships
  (data-virtual-cluster=false for small clusters)

* perf(editor): reduce issue detail mount cost

Parse long Markdown in smaller chunks without the duplicate initial sync, defer title and empty composer editors until intent, and keep the description editor eager to avoid layout shifts.

* chore(desktop): add navigation boundary lint rule (MUL-4741 Phase 2 prereq)

The tab Coordinator protocol requires that application code never
navigates directly (invariant 1: a Router location change without a
Coordinator token is a protocol error). Enforce it statically:

- renderer app code may not import useNavigate/Navigate from
  react-router-dom nor call router.navigate; src/platform is exempt
- the five known legacy sites (the RFC §8.1 migration checklist,
  cross-validated: the rule fires on exactly those and nothing else)
  carry inline eslint-disable directives tagged MUL-4741 — the Phase 2
  migration removes them one by one, and this rule holding with zero
  disables is the machine check that the migration is complete

* fix(views): open deferred pickers on click, align triggerRender types

Pointerenter warm-mounting swapped the trigger element mid-gesture: real
browsers re-hit-test so the click lands on the new trigger, but synthetic
pointer sequences (tests, assistive tech) keep dispatching on the detached
node and the first click dies. Upgrade now happens on click/Enter/Space
only — the same timing as Base UI's own trigger — with the in-flight click
stopped so the popup's just-mounted outside-press dismissal doesn't close
it in the same breath.

Also widen triggerRender to ReactElement<Record<string, unknown>> (React
19 defaults ReactElement props to unknown) and mount the
IssueContextMenuProvider in the swimlane test harness like IssueSurface
does in production.

* refactor(desktop): single-router tab sessions with Coordinator protocol (MUL-4741 Phase 2)

Replace the per-tab-router + <Activity> keep-alive model with the approved
single-router session architecture:

- TabSession: tabs are pure serializable state (url, resourceKey, virtual
  history stack, scroll memento). Persist v4 does the one-time legacy
  view-state import from v3; mountGeneration is deliberately unpersisted.
- Coordinator (platform/tab-coordinator.ts) is the only router writer: it
  reconciles THE app router to the active session URL with navigation
  tokens; a location change without a token is a protocol error handled by
  bounded recovery (invariant 1). The router history is never used — every
  reconcile is a replace; back/forward are session-stack operations.
- ActiveTabHost mounts exactly one tab, keyed on tabId:mountGeneration.
  reload() = generation bump + active-scope query invalidation (never
  router.revalidate, never a global cache invalidation). Warm switches
  restore scroll pre-paint; cold restores pre-size containers from the
  memento's saved scrollHeight and settle when data lands.
- resourceKey dedup (pathname only) replaces exact-path dedup: opening
  /slug/issues?filter=b focuses the existing issues tab (RFC §8.2,
  deliberate semantic change).
- All five §8.1 legacy navigation sites migrated (index <Navigate>, error
  page recovery, workspace-layout login bounce, overlay parking, shell
  back/forward); their MUL-4741 ratchet eslint-disables are removed, so the
  navigation boundary rule now holds with zero exemptions outside
  src/platform.

* feat(issues): register board columns and list scroller for scroll mementos

Per-container scroll registration for the MUL-4741 tab session memento:
board columns key by group id (each column's offset restores
independently, the per-column split Linear ships), the list view keys as
"list". Chat and issue-detail already carry the marker.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(tabs): pull-based scroll restoration fed into virtualized lists (MUL-4741)

Rebuild the restore side of the memento protocol on first principles (the
model Linear ships): a saved offset is an INPUT to the mounting view, not a
post-hoc DOM mutation from outside.

- ScrollRestorationProvider (views/platform): views pull their saved offset
  while mounting. Virtualized lists feed it into Virtuoso's initialScrollTop
  so the first render already materializes the rows around it — this
  replaces the pushed spacer+scrollTop hook, whose foreign spacer deadlocked
  against Virtuoso's own height model (restore landed the viewport in
  phantom space, Virtuoso rendered nothing, and the spacer's removal
  condition could never be met → blank issue detail). Plain containers
  assign the offset at ref-attach, pre-paint. Web has no provider and
  behaves as before.
- Memento keys gain a route dimension (`${pathname}::${containerKey}`) and
  capture now also fires before in-tab navigation, so back/forward restores
  each route's own offsets and same-named containers on different routes
  no longer collide.
- commitScrollMemento uses REPLACE-per-route semantics: a container
  scrolled back to 0 clears its stale offset instead of resurrecting the
  old position on the next visit.
- List view gets the same estimate alignment as the board (36px rows into
  the seed spacer and defaultItemHeight), which keeps the shared scroller's
  height truthful from the first frame so the restored offset sticks.

Known gap: chat's bottom-anchored list captures offsets but has no restore
consumer — intentional, it re-anchors to bottom on mount.

* perf(editor): make unlabelled code fences plaintext instead of auto-detected

Follow-up to the issue-detail mount work: lowlight's highlightAuto runs
every registered grammar over the full block for code fences without a
language, which dominated mount cost on code-heavy comments. Extract a
shared syntax-highlight module whose auto fallback deterministically
renders plaintext; explicitly labelled languages highlight as before.
Also ignore .gstack/.

* perf(issues): lazy-mount column-header popups, right-size swimlane seed

Trace analysis of tab/view switching (30s session): a swimlane mount spent
its largest slice on eagerly-mounted header machinery — ~170 tooltip roots
(one per lane x status cell add-button), 13 column dropdown-menus, and up
to 30 fully-materialized lanes from the generic seed count.

- DeferredTooltip (views/common): renders only the trigger until first
  hover, then mounts a controlled Tooltip anchored to the SAME element
  (no trigger swap, so mid-gesture events never land on a detached node);
  ui TooltipContent grows an `anchor` passthrough for it.
- Board/list/swimlane header add-buttons and hide-column dropdowns now
  defer via DeferredTooltip / DeferredPopup (which gains an ariaHasPopup
  option for menu triggers).
- Swimlane lane seed drops 30 -> 6 (a lane row is ~300px+; a viewport fits
  ~3) on both the pre-scroll seed and Virtuoso's initialItemCount.
- openTab gains an `activate` option so "open and focus" paths (pinned-tab
  redirect, explicit open-in-new-tab) are ONE store write instead of
  openTab + setActiveTab back-to-back — one full subscriber pass per user
  action instead of two.
- Dev-only breadcrumb logs IssueSurfaceContent's remount key: the trace
  showed the surface mounting twice inside one task, and the my-issues
  relation toggle is one confirmed key-flip source; the log ties the next
  trace's mounts to exact key transitions.

* perf(issues): stop double full-tree render passes on surface interactions

Trace forensics on view switching showed every interaction paying TWO full
surface render passes (React's own Cascading Update marker sits between
them): entering swimlane flips controller-level loading state (loadProjects
enables the projects query), and any such flag flip re-rendered the entire
unmemoized view tree (~600-1000ms dev per pass).

- Memoize BoardView / ListView / SwimLaneView: controller/data outputs are
  already useMemo/useCallback-stable, so a controller flag flip now
  re-renders the header, not the whole board. The one unstable prop —
  BoardView's inline assigneeGroups.flatMap — moves into a useMemo.
- Selection reset on mount swapped the initial empty Set for a NEW empty
  Set, buying a guaranteed extra full pass per surface mount; functional
  bail keeps the reference when nothing was selected.

* perf(ui): drive sidebar resize by direct DOM writes, drop motion/react

Trace analysis showed sidebar motion.div mounts costing ~1s across a
session. Width previews during drag now write straight to the two layout
shells (CSS disables their transitions while data-sidebar-resizing is set);
React only sees the single committed width on pointer-up, and framer-motion
leaves the sidebar entirely.

* fix(issues): wire swimlane's outer scroller into tab scroll restoration

Review blocker on #5403: board/list/issue-detail register their scroll
containers with the tab session memento protocol, but the swimlane outer
scroller did not — under the single-router architecture an inactive tab
unmounts, so a deep-scrolled swimlane returned at top after a tab switch
or reload.

Same wiring as the other surfaces: data-tab-scroll-root="swimlane" for
capture, useRestoredScrollRef in the scroller's attach callback for the
pre-paint assignment, and the saved offset into the lane Virtuoso's
initialScrollTop. Regression test asserts both the capture marker and the
restored offset.

0d38288dbd MUL-2926 feat(editor): support markdown checkbox task lists (#3593) (#3657)
* feat(editor): support markdown checkbox task lists (#3593)

Render `- [ ]` / `- [x]` as interactive checkboxes in the issue content
editor, matching GitHub / Notion.

- Register TaskList + a patched TaskItem in the shared extension factory.
  Both ship their own markdown tokenizer / renderMarkdown, input rules, and
  a checkbox NodeView; the taskList tokenizer is consulted before marked's
  built-in list tokenizer, so `- [ ]` becomes a task while a plain `- ` still
  falls through to the bullet list.
- Patch TaskItem's keymap to share PatchedListItem's split -> lift Enter
  chain (double-Enter on an empty item exits the list); nested: true enables
  sub-tasks and nested round-trips.
- Add a "Task list" entry to the bubble-menu list dropdown (+ i18n for en /
  zh-Hans / ja / ko).
- Style task lists in prose.css for both the editor ([data-type="taskList"])
  and the readonly remark-gfm output (.contains-task-list); completed items
  render muted.

Readonly already rendered task lists via remark-gfm; this brings the editable
view to parity. Adds markdown round-trip and readonly checked-state tests.

MUL-2926

Co-authored-by: multica-agent <github@multica.ai>

* fix(editor): keep readonly nested task lists block-laid-out (#3593)

The shared `display: flex` rule on task-list items broke nested task lists in
the readonly view. remark-gfm renders a task item as
`<li><input> text <ul>…</ul></li>` — no body wrapper — so a nested list is a
direct sibling of the checkbox and text, and flex pulled it onto the same row.
The editor's Tiptap NodeView wraps the body in a `<div>`, so it was unaffected.

Split the task-list CSS into separate editor and readonly blocks: the editor
keeps the flex row; readonly stays a block list item with an inline checkbox so
a nested `<ul>` drops below and indents under its parent. Adds a readonly test
that pins the nested DOM shape (nested `<ul>` inside the parent `<li>`), so a
future remark-gfm change that wraps the body fails loudly.

MUL-2926

Co-authored-by: multica-agent <github@multica.ai>

* feat(editor): convert `- [ ] ` typing into a task list (#3593)

TaskItem's built-in input rule only converts `[ ] ` / `[x] ` typed at the start
of a plain paragraph. When the user types the GitHub-style `- [ ] ` the leading
`- ` first turns the line into a bullet, and the built-in rule no longer fires —
so `[ ]` stayed as literal text and nothing became a checkbox.

Add an input rule on PatchedTaskItem that catches the checkbox token when it is
the entire content of a freshly-typed list item (bullet or ordered) and converts
just that item into a task item (deleteRange → liftListItem → toggleList). The
anchored regex means it only fires on an item whose whole content is `[ ] ` /
`[x] `, so sibling items in the same list are left untouched.

Adds typing-level tests (real input-rule simulation) covering `[ ] `, `[x] `,
`- [ ] `, `- [x] `, the mixed-list split case, and the plain-bullet no-op.

0d51614c9c feat(editor): text highlight (==text==) in description & comments [MUL-2934] (#3661)
* feat(editor): support text highlight (==text==) in description & comments

Adds a single-color (yellow) text highlight mark to the shared rich-text
editor, round-tripped through stored Markdown as ==text==.

- HighlightExtension: @tiptap/extension-highlight + @tiptap/markdown hooks
  (markdownTokenizer/parseMarkdown/renderMarkdown) so ==text== <-> <mark>
  round-trips; inner inline formatting preserved via inlineTokens.
- Bubble menu: highlight toggle button (Mod-Shift-H), i18n in 4 locales.
- Read-only renderer: highlightToHtml lowers ==text== -> <mark> (skips code
  and math); rehype-sanitize schema whitelists <mark>. Nested Markdown inside
  a highlight still parses via the existing rehype-raw step.
- prose.css: single yellow <mark> style, legible in light/dark.

Pinned @tiptap/extension-highlight to exact 3.22.1 to match @tiptap/core
(>=3.23 expects a getStyleProperty export core 3.22.1 doesn't have).

Web/desktop only. Mobile (native md4c, no == syntax, no custom renderers)
is tracked as a follow-up. MUL-2934.

Tests: editor round-trip (cross-process serialization protocol), readonly
<mark> rendering + sanitize, and the ==->mark transform incl. code-skip.

Co-authored-by: multica-agent <github@multica.ai>

* fix(editor): align highlight boundary rules across editor & readonly

Addresses two boundary bugs from review (PR #3661):

1. A == inside inline code/math could close a highlight when the opening
   == was outside the literal span (e.g. ==a `b==c` d== wrongly became
   <mark>a `b</mark>c` d==). Both the editor tokenizer's lazy regex and the
   readonly transform only guarded the opening fence, not the closing one.
2. The readonly transform matched across blank lines (==a\n\nb==) while the
   editor lexes those as two literal paragraphs — a storage↔editor↔readonly
   mismatch.

Fix: extract one shared matcher (utils/highlight-match.ts) used by BOTH the
editor tokenizer and the readonly lowering, so the rules can't drift. It skips
fences that fall inside code/math literal ranges (open or close) and caps the
inner span at the first blank line.

Tests: shared-matcher unit tests + both repros covered on the editor
(round-trip/HTML) and readonly (transform + rendered DOM) sides.

* fix(editor): handle CRLF in highlight blank-line boundary

BLANK_LINE_RE only matched LF, so a CRLF blank line (==a\r\n\r\nb==) was not
recognized as a block boundary and got highlighted. Widen to \r?\n[ \t]*\r?\n.

Tests: CRLF blank-line (no highlight) + CRLF soft-break (still highlights) on
the matcher, readonly transform, and editor sides.

91c1e51411 feat(editor): add / slash-command palette for invoking agent skills (#3159)
* feat(editor): add / slash-command palette for invoking agent skills

Adds a `/` trigger in the chat box that opens a popover listing the active
agent's skills. Selecting an item inserts a `[/label](slash://skill/<id>)`
token; the daemon extracts those IDs in `buildChatPrompt` and emits an
"Explicitly selected skills:" block using the canonical names from the
agent's skill registry — labels are display-only and never trusted.

Built on Tiptap's `Mention` extension so the suggestion lifecycle,
keyboard routing, and IME handling mirror the existing `@` mention UX.
Item list is sourced from the React Query workspace cache (no per-keystroke
fetch). Gated behind a new `enableSlashCommands` prop so only `chat-input`
opts in; other `ContentEditor` consumers (issue editor, comments) are
unaffected. Read-only markdown surfaces render the token as a `.slash-command`
pill via a custom link renderer + sanitize-schema/url-transform allowlists.

Closes #3108

* fix(i18n): add slash_command editor copy for ko/ja

The PR added slash_command popover empty-state keys to en + zh-Hans only;
locales/parity.test.ts requires every locale to cover every EN key, so ko
and ja failed CI. Add the two keys (no_skills_configured, no_results)
matching existing skill terminology (스킬 / スキル).
