Improvement

Failure clusters, investigations, improvement proposals, remediation through CodeBook, and release channels.

• Failure clustersThe failure-signal interface that groups alerts, failed case results, online scores, review findings and incidents into clusters without flooding anyone with tickets.
• InvestigationsThe investigation assistant's contract: model calls through Bookbag SSO under a budget, read-only access to evidence under the person's own permissions, and separation from production scoring.
• ProposalsWhat an improvement proposal contains, who may write and dispatch one, the events it emits to peers, and how CodeBook turns it into a card with a bound and protected paths.
• RemediationHow a proposal is dispatched to CodeBook as a card, how progress and outcomes come back, and what EvalBook does and does not do while a fix is attempted.
• Release channelsThe channels a suite or scorer version moves through, from draft to shadow to active, and the governed activation that is the only way to make one the gate.
