+### Fixed
+
+- Desktop release policy now fail-closes on platform parity: one version and
+  exact source commit must produce verified macOS DMG/updater, Linux host, and
+  Windows Setup/Squirrel artifacts before any tag or GitHub Release can be
+  published. Windows signature status is disclosed and unsigned output remains
+  accepted until a trusted signing identity is adopted. A missing platform
+  pauses the whole release instead of leaving users on a stale update line.
+
+- Cowork new-file prompts now start blank. Names with an explicit extension are
+  preserved, while extensionless names receive the active section's `.md`,
+  `.whiteboard.json`, `.txt`, or `.slides.json` default.
+- Presentation canvases anchor at the top of their scrollable stage, and the
+  Excalidraw hamburger menu escapes the editor's inner clip into a bounded,
+  scrollable overlay so its complete menu remains visible and interactive.
+- Cowork Code uses the normal light surface with readable dark text in light
+  mode while retaining its navy editor treatment in dark mode.
+- Offline shell fallbacks always resolve service-worker requests with a valid
+  response instead of producing a rejected FetchEvent conversion error.
+- Cowork's bare Option/Alt shortcut now carries the mic control belonging to
+  the focused Notes, Docs, or agent input and uses a capture-phase fallback
+  when the macOS desktop shell swallows the corresponding keyup.
+- Long Cowork Notes give CodeMirror a finite editor frame and scroll through
+  its actual viewport in Write mode.
+- Leaving Cowork, changing sections, or opening another file now destroys the
+  outgoing Yjs document and reloads the authoritative workspace file into a
+  fresh document. The stale browser recovery copy that could resurrect or
+  repeatedly duplicate prior text has been removed.
+- Files directory, tree, text, and content reads now paint from the host mirror
+  immediately. One explicit background refresh coalesces the expensive channel
+  computer export and repaints the current listing when it completes.
+
+### Added
+
+- Files now keeps `/workspace` and the five Cowork folders first in its visual
+  navigation rail, with all remaining root files and folders grouped under an
+  expandable **Other** disclosure without changing the underlying filesystem.
+- Selecting a Markdown file in Files exposes **Download - DOCX**, backed by an
+  authenticated, contained Office Open XML export.
+- Desktop workspace navigation can collapse to a compact channel-icon rail and
+  expand again. The profile-bound preference persists, while the existing
+  mobile drawer remains unchanged.
+
+### Tests
+
+- Browser coverage toggles both Cowork editor and agent dictation through bare
+  Option/Alt, scrolls a 120-line Note, and proves section changes, full Cowork
+  navigation, and a five-line external replacement all reopen exactly once
+  without a recovery prompt.
+- A fake Apple channel computer with an intentionally slow export proves cached
+  Files reads stay responsive, simultaneous refreshes coalesce, and guest-only
+  files appear after the background refresh.
+- Browser and server coverage verify blank Cowork naming, default and explicit
+  extensions, presentation-menu stage bounds and pointer hit-testing, light
+  Code contrast, Files grouping, real DOCX ZIP contents, and persistent
+  desktop-only sidebar collapse.

 ## Versioning
 
 - Semantic versioning on `package.json`.
 - **Do not** reuse a published version tag for different bits.
-- A release requires a unique version, changelog, exact tag, verified public
-  artifact, and platform-appropriate clean installation evidence.
+- A desktop release requires one unique version and exact commit, changelog,
+  complete Mac + Linux + Windows artifact matrix, and clean-install plus
+  prior-to-new update evidence on every platform. Partial platform releases
+  under the shared product version are prohibited. If one platform is blocked,
+  the entire tag/publication waits.
 - GitHub Release notes are a first-class product artifact. They must enumerate
   every user-visible fix and feature accepted for that release, using the same
   numbered ledger as the originating request when one exists. A short summary
   can introduce that ledger but cannot replace it.
 - macOS verification must use the exact publicly downloaded artifact, preserve
   Application Support, and prove signature/ticket/Gatekeeper, launch, version,
   loopback behavior, and retained state on the retained release host.
+- Linux verification must use the digest-qualified release archive and prove a
+  real systemd update, health-failure rollback, and retained `/var/lib/1helm`.
+- Windows verification must prove the Setup/Squirrel signature status, clean
+  install, old-to-new update, loopback health, WSL lifecycle, and retained
+  application data on Windows 11 x64. Do not substitute a self-signed
+  certificate or block an otherwise accepted release solely because the
+  artifacts are honestly disclosed as unsigned.
 
 Never hand-edit only a deployment target to fix the product. Fix in git,
 review, merge, and redeploy the exact source commit.
