Safety statement

No conflicts were auto-resolved. The bot never uses --force, reset, checkout --ours/--theirs,
or auto-merge. This is a normal two-parent merge commit whose tree was verified against a
non-mutating merge probe before it was pushed.

Manual verification checklist

• Hotspot paths reviewed: upstream intent and Marcode intent are both preserved.
• Coupled vendored subtrees reviewed when flagged.
• Web/mobile/desktop UI surfaces checked at 390px and 820px when UI hotspots changed.
• Provider-focused tests run when apps/server/src/provider/** changed.
• Branding asset checks run when asset paths changed.
• All required checks green before this leaves draft.
