Improvements

• Read conversation token and cache totals from running counters in (status), without scanning initialized histories. Migrate older conversations once and persist the totals across reopening and compaction.

Fixes

• Separate mission output admission from aggregate token reservations. Check the finalized provider request against the available context and supported output limits.
• Explain mission-tool refusals after cancellation, replacement or quarantine, using the state associated with the exact request context.
• Serialize legacy usage migration while allowing appends and rotation. Recover interrupted checkpoint writes without losing or double-counting usage, and normalize malformed or negative counters.
