KanBorg 1.2.26 — reliable capacity monitoring

Capacity monitoring now preserves valid historical readings across temporary failures and prevents unknown grant balances from activating paid fallback. Codex reads quota before models, so model discovery failures cannot consume the reporting timeout. Empty quota responses preserve the last same-account reading, and late Claude responses cannot replace a newer sign-in's snapshot.

Provider settings invalidate capacity immediately, including changes made during a refresh. The capacity panel includes Refresh capacity, honors provider cooldowns, and retains readings on refresh failure. Routine monitoring no longer launches Claude auth-status commands. Expired reset windows and invalid balances cannot authorize automatic spending.

Also includes the scoped existing-chat Codex CLI adapter previously tested in the isolated integration build. Transport acceptance remains separate from receiver acknowledgement and action completion.

Validation: 114 desktop tests, 10 Claude usage tests, desktop/web typechecks, local bundle signature, disk-image checksum, and isolated legacy-update/startup/project-restoration/coordinator-resume smoke test passed.

Live account limitations: expired Claude authorization still needs renewal; old manually entered grant balances need confirmation or organization-report recovery. The release does not claim those account connections were repaired or their live balances verified. No production credentials were changed.
