Summary

• Deliver the approved 34-file tooling cohort: typed Script leases, qualified cleanup transport/evidence retention, Smoke lease recovery, and bounded writer preservation authority.
• Add Kent 2.9 CLI Janitor decoding from qualified Kit 88eac2e with independent provenance; retain runtime 302 and generator 5af pins.
• No application, build, or CI source changes relative to remote master b755826.

Verification

• Complete current-cohort source suite: 14 test launches passed, including 100 Janitor cases and 22 Smoke cases.
• Builder/manifest closure, actual consumer compatibility, donor parity, and diff checks passed with stable source fingerprint.
• Historical frozen v90 graph qualified separately on its original source pair; no historical snapshot rewrite.
• No device or live Kent 2.9 runtime qualification claimed.

Boundary

Source delivery only. No installed checkout update, live Workflow mutation, Task migration, Kent upgrade/restart, tags, or release publication.
