JAgentDesk v0.9.55

Figma browsing, rendering and prototype playback improvements. JAgentDesk draws designs and
plays frames itself; viewing and playback do not require Figma Desktop or the Figma Link plugin.
This is an incremental release, not full Figma Design feature parity.

Changed

• Browse files: a desktop file picker opens Figma's Files website in an isolated guest.
  Selecting a supported file URL hands it to JAgentDesk's canvas. Website sign-in remains separate
  from the daemon's REST connection. Manual file/team URLs and Link controls move under Advanced.
• Large-file navigation: include frames nested in Sections, preserve flow starting points,
  expand truncated Section metadata on demand and load detailed frame trees only where needed.
  Overview, loading, failed content and ready content have distinct visible states.
• Sharper canvas: unavailable fonts use Figma-exported outlined SVG glyphs. Raster fallback
  resolution follows zoom and display density, with separate cache keys for version, format and
  bounds. Correct fallback placement, opacity, shadows, linear-gradient handles and stroke alignment.
  Complex stroke clipping uses a node fallback rather than dropping parts of the outline.
• Scoped prototype playback: fetch only the frames currently needed for the stage, overlays
  and transitions, in batches of at most ten. Reuse the canvas's versioned frame cache, release
  unused frame assets and show loading/failure with targeted Retry until required images and
  glyphs have painted. A mounted canvas is no longer reported as complete content.
• Sections and editing connection: add Section selection and move-preview handling, plus
  an independent editing-connection panel. A write requires the connector's authorization and
  readback; a local preview or pending operation is not presented as a saved Figma change.
  Chat keeps the provider and model selected by the user.
• Comments: improve search, sorting, filters, refresh and desktop/compact layouts. Comment
  region data can travel through the protocol without being collapsed to a point.
• Less repeated work: coalesce identical in-flight reads, reuse freshly verified metadata
  and stop unchanged-version polls from clearing the canvas. Historical reads cannot replace
  the live-version memo; stale poll results cannot roll back a confirmed write readback.
• File-access errors identify the connected account and preserve Figma's denial details.

Verification and current limits

• Focused regression tests, app typecheck and daemon build passed. Real Electron checks used
  a file with over 3,600 frame nodes; the same design frame was visually compared at 100%,
  200% and 332% zoom on a DPR-2 display.
• Continuous pan on a loaded viewport measured about 56–58 compositor frames per second.
  One open/play/close run measured approximately 184 MB peak app-process-tree growth; these
  measurements are not a performance guarantee for every file or platform.
• Cold loading still misses the three-second target: the latest real file needed about
  29 seconds for complete viewport content. Initial prototype content can also take many
  seconds while Figma API/export requests finish. A warm UI reopen completed its viewport in 0.44 seconds with no new REST requests in that run.
• Website sign-in and file selection, authenticated writes to the original design, native mobile
  rendering and multi-user presence/follow have not passed end-to-end acceptance. This release
  does not claim full Figma collaboration or editing support.
• Some context-dependent backdrop exports and advanced prototype behavior can still differ
  from Figma. Comment pins, mentions, resolve/reopen and other unimplemented Design features
  remain outside this release's verified behavior.
