Requires spt-core **v0.39.1 or newer** and Oh My Pi **v16.3.15 or newer**. Update with `spt adapter update omp-spt`, then restart existing endpoints so they load the corrected launch environment.

### Fixed
- **The window title's idle glyph and animated busy spinner work again.** Oh My Pi 17 changed its RPC-hosted behavior: it now disables window-title updates by default and drops the extension's `setTitle` requests unless the host opts in with the `PI_RPC_EMIT_TITLE=1` environment variable. spt-core hosts OMP over RPC, so on OMP 17 the idle glyph at session start and the braille busy spinner on each turn silently stopped appearing. The launch now sets `PI_RPC_EMIT_TITLE=1` for the hosted OMP process, restoring both. Existing endpoints pick this up on their next restart.
