Render archived sessions as a flat list in VS Code without project-root subfolders.
Hide the "Open in Side Panel" session action in VS Code.
* fix(ci): pass target architecture to beforeBuildCommand
Set TAURI_ENV_TARGET_TRIPLE environment variable before running
build commands to ensure sidecar binary matches target architecture.
Problem:
- CI builds both arm64 and x86_64 targets in parallel on arm64 runner
- beforeBuildCommand executes before Tauri sets TAURI_ENV_TARGET_TRIPLE
- build-sidecar.mjs fallbacks to process.arch (arm64 on CI runner)
- Both parallel tasks build arm64 sidecars, second task overwrites first
- Result: x86_64 releases contain arm64 sidecar → startup failure on Intel Macs
Solution:
- Explicitly set TAURI_ENV_TARGET_TRIPLE in CI workflow
- Add architecture verification step to detect mismatches early
Evidence:
- Official DMG OpenChamber_1.8.5_darwin-x86_64.dmg contains arm64 sidecar
- Local build with explicit env var produces correct x86_64 sidecar
- /Applications/OpenChamber.app/Contents/MacOS/openchamber-server: arm64
- packages/desktop/src-tauri/sidecars/...: x86_64 (with env var)
Fixes startup failure on Intel Macs where official x86_64 DMG
contains arm64 sidecar binary, causing indefinite loading screen.
* fix(ci): normalize architecture names in verification step
Fix architecture mismatch where macOS 'file' command reports ARM binaries
as 'arm64' but verification expects 'aarch64', causing false negatives
in ARM builds.
Changes:
- Update grep pattern to include 'arm64' in extraction
- Add normalize_arch() function to map arm64 -> aarch64
- Improve debug output to show raw and normalized architectures
- Update error messages to show both raw and normalized values
This fixes the issue reported by @btriapitsyn where ARM builds would
fail verification even with correct artifacts, because:
- macOS file command reports: 'Mach-O 64-bit executable arm64'
- Old grep pattern only matched: 'x86_64|aarch64'
- Result: empty string != 'aarch64' → false failure
The normalization ensures consistency between:
- macOS file output (arm64/x86_64)
- Rust/Cargo naming (aarch64/x86_64)
- Tauri target triples (aarch64-apple-darwin/x86_64-apple-darwin)
Fixes architecture verification for both ARM and Intel builds.

* fix: keep macOS traffic-light buttons in the correct position on load

* fix: recover missing providers and agents after fast startup
Retries provider/agent loading when connection is up but core config is still empty
Prevents cold-start state where models/agents appear only after manual project switch
Keeps startup responsive with throttled background recovery in app bootstrap
The CLI tunnel startup generated a bootstrap token but discarded it,
then built a URL with ?token=<uiPassword> which the tunnel auth system
ignores. Remote users always saw 'Tunnel access required' with no way
to authenticate.
Capture the bootstrap token, build the /connect?t=... URL, and pass it
through onTunnelReady so the CLI prints the correct one-time connect
link (and QR code).

packages/ui/src/components/chat/MobileSessionStatusBar.tsx
- What: Added `min-w-0` to the title row flex container and `flex-1 min-w-0` to the session title span inside `SessionStatusHeader`.
- Why: The flex container had `min-width: auto` (browser default), causing the title to expand beyond its constrained parent and bleed over the running/unread indicators and New button. `truncate` was a no-op without a width ceiling on the span. Fixes#556.
