Four related desktop session-management bugs: - Pins lost until refresh: pinned sessions are joined against the paginated in-memory session list, so a pinned chat that aged off the most-recent page got evicted on the next refresh (every message.complete triggers one) and the Pinned section went empty. mergeWorkingSessions -> mergeSessionPage now also preserves pinned rows (matched by live id or lineage root). Pin id checks in the chat header, command center, and delete/archive are normalized to the durable sessionPinId so pins survive auto-compression. - Stuck on "Starting Hermes" after sleep: macOS sleep drops the renderer WebSocket; nothing reconnected on wake so the composer stayed disabled. The gateway boot hook now auto-reconnects with backoff on close/error and on wake signals (powerMonitor resume/unlock-screen IPC, window online, visibilitychange). connect() gains an open timeout so a hung reconnect can't deadlock in 'connecting'. Composer placeholder distinguishes "Reconnecting to Hermes" from a cold start. - Loses chats from itself: the same hard-replace that dropped pins also dropped loaded sessions; mergeSessionPage keeps them. - Multiple copies/branches in search: /api/sessions/search deduped only by raw session_id, so compression segments and branches surfaced as separate hits. It now dedupes by lineage root and returns the live compression tip, matching the session_search tool's behavior.

// by default on modern Windows. It's a redirector that opens the
|
||
// Store window if no Store Python is installed. Running it for
|
||
// `-m venv` would either succeed (real Store install — fine) or
|
||
// pop the Store dialog (bad UX during boot).
|
||
// (2) `py.exe` (Python launcher) is missing from per-user installs
|
||
// that didn't check the launcher option, so PATH-only checks
|
||
// miss real Python 3.13 installs (user-reported case).
|
||
//
|
||
// We also restrict ourselves to Python 3.11–3.13. 3.14 is the latest
|
||
// CPython but several Hermes deps (notably pywinpty's Rust-built
|
||
// windows_x86_64_msvc crate) don't yet publish 3.14 wheels, and
|
||
// `pip install -e .` falls back to source-build, which fails without
|
||
// a Rust toolchain. install.ps1 sidesteps this by pinning to 3.11
|
||
// via uv; until we add the same uv-managed Python pathway here, the
|
||
// simplest fix is to refuse 3.14 detection and let the NSIS prereq
|
||
// page offer to install 3.11 alongside.
|
||
//
|
||
// Strategy: probe in three passes, in order from most-precise to

// a real Python install. Versions are explicit so we
