v2.15.0

Fixes the user-reported "freezing under load" and view-switch lag found via a dogfood-log RCA, finishes the remaining session-reliability hardening from the v2.14.0 RCA, makes the installer and auto-updater integrity-safe, and wires (inert) OSS code signing.

Fixed — hook-RPC timeout floods / UI freezes (Issue A1, A2)

  • hooks.signal no longer does a renderer workspace.list round-trip on every signal. A 2s-TTL coalescing cache collapses a tool-heavy turn's bursts into ~1 round-trip and serves the last-known list when the renderer is throttled — stopping the PostToolUse timeout floods that froze the UI and, at worst, blocked the daemon event loop into a forced respawn.
  • The Claude Code bridge retries transient connect-errors within its 2s budget (and never re-fires a request it already wrote), so a brief main-process restart window no longer drops hooks.

Fixed — session reliability (RCA A1/A9, A4, A6)

  • Partial-list reconcile now re-queries the daemon before clearing a live ptyId absent from a non-empty session list (2-strike guard), closing the last destructive-session-loss path the v2.14.0 RCA left open.
  • The daemon health probe tolerates a busy-but-responsive daemon — daemon.ping reports event-loop lag, thresholds raised to 5 strikes / 5s — instead of mistaking load for a hang and force-respawning.
  • DaemonClient.connect retries transient named-pipe errors (EPERM/ECONNRESET) with backoff; ENOENT still fails fast.
  • Session-pipe bind retries on EADDRINUSE, so a pane no longer dies when a prior pipe has not yet released its name.

Fixed — view-switch / multiview performance

  • WebGL terminal contexts are no longer disposed the instant a pane is hidden. A short grace period (cancelled on re-show) eliminates the GPU-context create/destroy thrash behind workspace-switch and multiview→single-view lag.

Added — auto-update integrity (fail-closed)

  • The updater downloads the Setup.exe and verifies a CI-published SHA-256 (update-manifest.json) before launching it; a tampered or unverifiable artifact is never run. Previously it opened an unverified URL.

Added — hook-RPC flood observability

  • A rolling 30s summary of slow/failed workspace.list resolutions is logged (escalating to a warning on a flood), so degradation is visible without hand-tallying bridge.log.

Changed — install funnel

  • install.ps1 now downloads the prebuilt, SHA-256-verified Setup.exe by default instead of always compiling from source. Build-from-source is opt-in (-FromSource / WMUX_FROM_SOURCE=1).

Changed — docs & security accuracy

  • Corrected the README "RunAsNode disabled" claim and reconciled SECURITY.md / PROTOCOL.md with the actual code (token entropy, icacls behavior, intentionally-disabled asar-integrity fuse). Removed the permanently-disabled EditorPanel "Save" affordance.

Added — code-signing pipeline (inert until configured)

  • release.yml is wired for SignPath Foundation (OSS) Authenticode signing of the installer, gated on a signing secret so it is a no-op until configured. Binaries remain unsigned (SmartScreen "unknown publisher") until the certificate is provisioned.
