Global settings silently reset on restart; window-local changes don't propagate across windows

[moonray]

Symptom

Global user settings revert to defaults every time RPCE restarts, and changes made in one window don't appear in other open windows. Affected settings include:

• Oracle / planning model
• Context Builder agent selection
• Sub-agent role overrides (explore / engineer / pair / design)

Setting one of these in window A leaves other open windows showing the old value until the app is restarted (e.g. A shows Oracle = fable while every other window keeps gpt-5.5).

Root cause

1. An unsupported schema is indistinguishable from "no settings." A globalSettings.json whose schemaVersion is newer than the running build supports decodes the same as a missing file, so the store silently falls back to in-memory defaults on every launch. Settings appear to never persist, with no signal to the user that the file is being ignored.
2. No live cross-window re-sync. Each window caches global settings locally and the shared GlobalSettingsStore doesn't publish changes to observing windows, so a change in one window only appears in the others after a restart.

Proposed fix

• Detect an on-disk schema newer than supported and surface it to the user: a banner explaining settings won't save, with one-click recovery that backs up the offending file and restores fresh current-schema defaults. The app must never auto-overwrite a schema it did not write.
• Publish objectWillChange on the global-defaults setters so windows observing the shared store re-sync live.

Status

Fix implemented with tests (cross-window propagation + JSON-only persistence / schema-block recovery), green locally. PR to follow and will reference this issue.

Man, I had the same headache with the schema mismatching and those settings just vanishing. I managed to hook a script together that force-syncs the store across instances and fixes the versioning bug so it actually sticks. It worked like a charm for me.

the settings i noticed not saved:
Oracle Model, Context Builder Agent, Agent Models window, Context Budget
Appearance, MCP Server, Tools (they weren't set at all at start, but i will check if they are saved next time I start)

these are the settings I touched so far.
