3b08456264 feat(views): block draft-fixing actions while attachments upload (#5465)
Submitting a composer mid-upload silently lost the file: the editor holds a
`blob:` placeholder that gets stripped during serialization, and the
attachment id does not exist yet, so the send succeeded without the file.
Chat and Quick Create gated this; manual issue create, Feedback's button,
comments, replies and comment edit did not.

Gate every action that FIXES a draft — Send/Create/Save, Cmd/Ctrl+Enter,
Enter on the title, and the manual/agent mode switches — behind one source
of truth: the editor document, which IS the upload queue. ContentEditor
publishes queue transitions via `onUploadingChange` (a transaction listener,
not `onUpdate` — that path is debounced and skips no-change emissions, and a
failed upload leaves byte-identical markdown, so the un-gate would never
fire). `useUploadGate` pairs that render state with an `isBlocked()` re-read
at submit time, since the shortcut paths never consult the button.

The publisher emits its current answer on subscribe rather than only on
flips: hosts outlive editor instances (comment edit remounts on cancel,
chat swaps by key on agent switch), and an editor torn down mid-upload would
otherwise leave submit wedged shut with no pending node left to reopen it.

Also fixes the failure toast that never fired: `uploadWithToast` only
reported errors if a caller passed `onError`, and none did, so failed uploads
removed their placeholder and vanished unexplained. `useEditorUpload` now
supplies it once for every composer.

Per MUL-4808: drops Quick Create's upload-time lock on the attach button
(files can queue), and leaves description autosave ungated by design.

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.

d6540a1869 fix(clipboard): support copy over http:// via execCommand fallback (#3810)
navigator.clipboard is only exposed in a secure context (https or
localhost). On self-hosted instances served over plain http:// it is
undefined, so every copy / "copy all" / export button silently failed and
left the clipboard empty (GitHub #3781).

Add a shared copyText(text): Promise<boolean> helper in
@multica/ui/lib/clipboard that prefers the async Clipboard API and falls
back to a hidden <textarea> + document.execCommand('copy') for non-secure
contexts. Migrate all direct navigator.clipboard.writeText call sites
(code blocks, agent transcript copy-all, token / webhook / issue-link
copy, etc.) to it, gating success side-effects on the returned boolean,
and remove the now-redundant copyMarkdown wrapper. Secure-context users
keep the native path unchanged.

39f43a9a98 refactor(editor): unify attachment rendering into a single <Attachment> component (#2850)
Collapse the five separate attachment render paths (file-card NodeView,
image NodeView, readonly markdown img/fileCard renderers, AttachmentList
standalone fallback, and the parallel packages/ui/markdown renderer) into
one <Attachment attachment={a} /> dispatcher.

Fixes a P0 visual regression: a PNG attached to a message but not inlined
in the markdown body used to render as a gray "file card" because
getPreviewKind() lacked an "image" branch and image rendering bypassed
the dispatcher entirely. Now every surface routes through <Attachment>,
so the same PNG renders as a real <img> with hover toolbar and
preview-modal everywhere.

Key changes:
- PreviewKind gains "image"; getPreviewKind() detects image/* + common
  extensions before the html/text branches (so svg stays image, not text).
- AttachmentPreviewModal gains case "image" (replaces the standalone
  ImageLightbox, which is deleted).
- New packages/views/editor/attachment.tsx owns all kind-aware routing
  (image | html | file) and dispatches preview modal + download via the
  existing useAttachmentPreview / useDownloadAttachment hooks. Subsumes
  the deleted AttachmentBlock.
- AttachmentInput.url accepts a forceKind hint so callers that *know*
  the structural kind (markdown ![](url), Tiptap image node) skip the
  filename-based autodetect — fixes a regression where empty or
  descriptive alt text would route an image to the file-card chrome.
- Tiptap NodeViews (file-card.tsx, image-view.tsx) shrink to thin
  wrappers that forward editor hints (selected, deleteNode, uploading)
  to <Attachment>.
- ReadonlyContent and AttachmentList each mount their own
  AttachmentDownloadProvider so url → record resolution works outside
  ContentEditor's provider.
- packages/ui/markdown gains optional renderImage / renderFileCard slot
  props; packages/views/common/markdown.tsx injects <Attachment> into
  those slots and threads message attachments through to chat /
  skill-file viewers.
- chat-message-list passes message.attachments to every <Markdown> call
  site and renders a standalone AttachmentList under each bubble for
  attachments not referenced in the body.

Tests: attachment.test.tsx covers 9 scenarios (record image / pdf / html;
url-only image with resolver hit and miss; uploading state; editable
delete; forceKind regression). attachment-preview-modal.test.tsx gains
image-dispatch cases. 652/652 unit tests pass.

5f1ced867c feat(editor): HTML attachments render like images (MUL-2345 v4) (#2798)
* feat(editor): HTML attachments render like images (MUL-2345 v4)

HTML attachments no longer wear the file-card chrome (icon + filename
row). They now render as a sandboxed iframe with a hover-revealed
right-top toolbar (Open / Download / Copy code), mirroring the image
attachment visual model.

- New HtmlAttachmentPreview owns the iframe + hover toolbar plus three
  states (loading / success / error). Failure mode keeps the toolbar
  pinned open and Open/Download enabled so the user is never stranded
  without an escape hatch — Copy code disables when the text body is
  unavailable.
- New AttachmentBlock thin dispatcher picks the renderer per kind:
  html + attachmentId + !uploading -> HtmlAttachmentPreview, else
  AttachmentCard. All three entry points (file-card NodeView, readonly
  file-card, standalone AttachmentList) call AttachmentBlock, so feature
  work on a new kind only touches one place.
- AttachmentCard collapses back to a pure file-card row UI: the inline
  HTML iframe branch (InlineHtmlIframe + inlineHtmlEnabled +
  showInlineHtml) is removed.
- AttachmentBlock added to the editor barrel export.

Sandbox/server-side defenses unchanged: sandbox="allow-scripts" (no
allow-same-origin), srcDoc, server still returns text/plain + nosniff
on the /content proxy.

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

* test(editor): pin three entry points to AttachmentBlock HTML route (MUL-2345)

Reviewer flagged that the v4 dispatcher refactor only had tests on the
shared AttachmentBlock + HtmlAttachmentPreview; the three real call
sites at file-card.tsx:59, readonly-content.tsx:279, and
comment-card.tsx:152 had no regression coverage. Reverting any one
would silently lose the inline HTML iframe path — the exact MUL-2330
regression we're meant to be locking down.

Each new test renders the real entry point with an HTML+attachmentId
fixture and asserts the dispatched iframe (sandbox=allow-scripts,
srcdoc) shows up while the AttachmentCard chrome (filename row) does
not. FileCardView and AttachmentList are exported from their files for
direct rendering, mirroring the existing CodeBlockView test pattern.

Mutation-tested locally: temporarily flipping each site back to
<AttachmentCard> turns its corresponding test red.

ceb967aefa feat(editor): inline HTML attachment preview + ```html block render (MUL-2345) (#2790)
* feat(editor): inline HTML attachment preview + ```html block render (MUL-2345)

* attachment-preview-modal: switch HTML iframe sandbox from "" to
  "allow-scripts" so JS-driven chart libraries render. The opaque-origin
  iframe still cannot touch cookies, localStorage, parent state, or
  top-nav — only scripts run.
* New shared AttachmentCard wired into the three attachment surfaces
  (file-card NodeView, ReadonlyContent file-card branch, comment-card
  standalone AttachmentList). HTML attachments now render inline via a
  sandboxed iframe pulled through the existing /content proxy; other
  kinds keep the original chrome behavior.
* New HtmlBlockPreview for fenced ```html blocks in ReadonlyContent —
  default preview iframe, source/Copy toggle. Two-layer code+pre unwrap
  mirrors the Mermaid pattern; unwrap now matches on language-* class
  because react-markdown invokes pre before the code renderer runs.
* CodeBlockView (Tiptap NodeView) renders an iframe preview for
  language=html with a CSS-hidden toggle to the editable source — the
  <NodeViewContent as="code"/> mount must remain in the tree.
* Shared use-attachment-html-text hook keeps inline and modal HTML
  rendering on the same React Query cache.
* Vitest coverage: allow-scripts assertion, attachment-card kind
  branches, readonly HTML iframe + Mermaid unwrap regression, NodeView
  editable + preview/source toggle.

No backend changes; server-side text/plain + nosniff defense kept.

* fix(editor): tighten attachment preview and pre unwrap gates (MUL-2345)

Addresses Reviewer REQUEST CHANGES on PR #2790:

1. URL-only text/html attachment cards no longer surface a dead Eye
   button. `AttachmentCard` previously allowed preview when
   `previewableFromUrl=true` regardless of kind, but the modal's
   `tryOpen` rejects URL-only text kinds because the `/content` proxy
   is ID-keyed. Drop the `previewableFromUrl` prop and gate the
   no-attachmentId path strictly to URL-previewable media kinds
   (pdf/video/audio).

2. Readonly `pre` unwrap now uses exact class-token matching. The
   previous `className.includes("language-html")` check also fired
   on `language-htmlbars`, silently stripping its `<pre>` wrapper.
   Use `/(^|\s)language-(html|mermaid)(\s|$)/` so only the exact
   tokens unwrap.

Regression tests:
- `report.html + no attachmentId` asserts no Preview button.
- `pdf URL-only` asserts Preview button still appears.
- `htmlbars` / `mermaidx` fences keep their `<pre><code>` wrapper.

454c8e3d1a feat: in-app preview for non-image attachments (#2528)
* feat(storage): add GetReader to Storage interface

Adds a streaming read method to the Storage abstraction so callers can
pull object bytes without forcing a full in-memory load. S3Storage wraps
GetObject; LocalStorage opens the file with path-traversal and sidecar
guards. Tests cover happy path, traversal rejection, sidecar rejection,
and missing key.

Used in the next commit by the attachment-preview proxy endpoint.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(server): add attachment preview proxy endpoint

GET /api/attachments/{id}/content streams the raw bytes of a
text-previewable attachment back to the client. Exists to (a) bypass
CloudFront CORS, which is not configured on the CDN, and (b) bypass
Content-Disposition: attachment which Chromium honors for iframe document
loads. Media types (image/video/audio/pdf) intentionally do NOT go through
this endpoint — clients render them directly from the signed CloudFront
download_url, which is already served with Content-Disposition: inline.

Hard cap: 2 MB. Larger files return 413. Anything outside the text
whitelist returns 415. The whitelist (isTextPreviewable) mirrors the
client-side dispatcher; the cross-reference comment in file.go flags
the manual sync until a JSON SSOT generator lands.

Response always uses Content-Type: text/plain; charset=utf-8 so a
hostile HTML payload can't be re-interpreted as a document. The
original MIME ships via X-Original-Content-Type for client dispatch.
Cache-Control: no-store so revoked attachment access takes effect
immediately on the next request.

Tests cover happy path (md), extension fallback when content_type is
generic, 415 (pdf), 413 (>2MB), foreign workspace (404 isolation), and
the isTextPreviewable table.

* feat(core/api): add getAttachmentTextContent + preview error types

Adds an ApiClient method that fetches the text body of an attachment via
the new /api/attachments/{id}/content proxy. Two typed errors —
PreviewTooLargeError (413) and PreviewUnsupportedError (415) — let the
preview modal render specific fallbacks instead of a generic failure.

Refactors the private fetch() into a shared fetchRaw() helper so the
new method inherits the standard infra: auth headers, 401 →
handleUnauthorized recovery, X-Request-ID, error logging, and the
ApiError contract. The previous draft bypassed all of these by calling
window.fetch directly.

* feat(views/editor): add AttachmentPreviewModal + Eye entry points

In-app preview for non-image attachments. An Eye icon now sits next to
the existing Download button on file cards / readonly file cards / the
standalone AttachmentList. Clicking it opens a full-screen modal that
dispatches by content_type:

  pdf:      <iframe src={download_url}>           — Chromium PDFium
  video/*:  <video controls src={download_url}>   — native controls
  audio/*:  <audio controls src={download_url}>   — native controls
  md:       <ReadonlyContent>                     — full markdown pipeline
  html:     <iframe srcdoc sandbox="">            — fully restricted
  text:     <code class="hljs">                   — lowlight highlight

Media types render directly from the signed CloudFront download_url
(server marks them inline-disposition). Text types fetch through the
new /api/attachments/{id}/content proxy via TanStack Query, wrapped
in useAttachmentPreview() so each entry point owns its own modal
state without depending on a global Provider mount.

Modal sizing: max-w-6xl × min(90vh, 100vh - 2rem) — slightly larger
than create-issue's max-w-4xl since PDF / video need room, but capped
to viewport on small screens. Sub-renderers use h-full to follow the
fixed modal height instead of viewport-relative units.

Images are intentionally NOT touched — the existing ImageLightbox
(extensions/image-view.tsx) already handles them correctly. The new
modal would be churn without user-visible benefit.

Adds i18n keys under attachment.* (en + zh-Hans) and registers
Preview/Download/Upload in the conventions glossary so future
translations stay consistent.

* chore(desktop): enable Chromium PDF viewer for attachment preview

Adds webPreferences.plugins: true to the main BrowserWindow so the
bundled Chromium PDFium plugin activates inside iframes — required for
the attachment preview modal's PDF dispatch. Default is false in Electron;
without it <iframe src=*.pdf> renders blank.

Security trade-off, accepted intentionally and documented inline:
  1. This window already runs with webSecurity: false + sandbox: false,
     so plugins: true does NOT meaningfully widen the renderer's attack
     surface beyond what is already accepted.
  2. The only PDFs that reach an iframe here are signed CloudFront URLs
     we ourselves issued; user-supplied URLs are routed through
     setWindowOpenHandler → openExternalSafely and cannot land in this
     renderer.
  3. Chromium's PDFium plugin is itself sandboxed and only handles
     application/pdf — no Flash/Java/other historical plugin surfaces.

If we ever tighten webSecurity / sandbox, the follow-up is to host the
PDF viewer in a dedicated BrowserView with plugins scoped to that view,
keeping the main renderer plugin-free.

Old desktop builds ship without the preview modal, so the Eye button
never appears and PDF preview is gated by the same release — zero
regression risk for users on stale clients.

352e838b01 fix(attachments): re-sign CloudFront download URLs at click time (#2407)
* fix(attachments): re-sign CloudFront download URLs at click time

The attachment download buttons opened `download_url` directly from cached
timeline/comment payloads. The signed URL is valid for 30 minutes, so a page
left open past that window would 403 with `AccessDenied` (MUL-2038 /
GitHub #2397).

- Add `GET /api/attachments/{id}` client method that re-signs on every call,
  validated by a stricter `AttachmentResponseSchema` (enforces `url`,
  `download_url`, `filename` so a malformed response degrades to the
  EMPTY_ATTACHMENT record instead of opening `undefined`).
- Introduce `useDownloadAttachment` hook with two execution shapes:
  - Web: synchronously open `about:blank` inside the click gesture to keep
    popup activation, then hydrate `location.href` after the fetch. Cannot
    pass `noopener` here — HTML spec dom-open step 17 makes that return
    null.
  - Desktop: skip the placeholder (Electron's setWindowOpenHandler rejects
    about:blank) and hand the fresh URL to `openExternal`.
- Wire the hook into the standalone attachment buttons (comment-card) and
  the inline `<img>` / file-card buttons inside `ReadonlyContent`. Inline
  buttons resolve the attachment id by URL match; external URLs fall back
  to `openExternal`.

* fix(editor): re-sign downloads from ContentEditor file/image NodeViews

The previous commit only wired the click-time fresh-sign through
ReadonlyContent + the standalone attachment list. The Tiptap NodeViews
inside ContentEditor still opened the raw URL with
`window.open(href, "_blank", "noopener,noreferrer")`, leaving two
download surfaces on stale signatures:

- Issue description (always renders via ContentEditor)
- Comment edit mode (transient ContentEditor instance)

- Add AttachmentDownloadContext + AttachmentDownloadProvider so NodeViews
  can resolve markdown URLs to an attachment id and call the existing
  `useDownloadAttachment` hook. The default fallback (no provider mounted)
  hands the raw URL to `openExternal`, keeping non-editor mounts unaffected.
- ContentEditor accepts `attachments?: Attachment[]` and wraps EditorContent
  with the provider.
- file-card.tsx and image-view.tsx NodeViews swap their `window.open(...)`
  calls for `openByUrl(href|src)` from the provider.
- issue-detail.tsx threads `useQuery(issueAttachmentsOptions(id))` into
  ContentEditor for the description.
- comment-card.tsx passes `entry.attachments` to both edit-mode editors.

66cb5d924a fix(editor): lift drag-drop overlay to outer container for better UX
When editors are empty, the internal drop overlay was too small to be
useful. Move the overlay to the parent container with a lighter style
so the drop target covers the full input area regardless of content.

- Create NavigationAdapter interface (push, replace, back, pathname, searchParams)
- Create AppLink component replacing next/link in 4 files
- Replace useRouter → useNavigation in 3 files (issue-detail, create-issue, create-workspace)
- Create WebNavigationProvider wrapping Next.js useRouter/usePathname/useSearchParams
- Move ~85 feature UI files (issues, editor, modals, my-issues, skills, runtimes) to packages/views/
- Add store singleton registration pattern (registerAuthStore, registerWorkspaceStore)
- Create data-aware wrappers in packages/views/common/ (ActorAvatar, Markdown)
- Update all app-layer imports to @multica/views/*
- Add @source directive for Tailwind to scan views package
