Fixed
- Anchor prompt-cache expiry to the main-session request, ignore subagent cache writes, and detect 5-minute or 1-hour cache tiers while preserving the configured fallback (#702).
Security
- Bound transcript request identifiers before grouping prompt-cache writes (#702).
Dependencies
- Update the development-only
@types/nodepackage from 26.1.2 to 26.2.0 (#711).
