rdmbair15m5-changelog-20260914-2144-tyrell-build24-preflight-backup
A fresh consistent Tyrell SQLite backup was created on rdmbair15m5 before any Build 24 canary mutation; the healthy Build 17/15 runtime was not changed and the Build 24 candidate remains untransferred and unlaunched.

What changed
- Created a consistent preflight SQLite backup at
/Users/richh/Library/Application Support/Tyrell/backups/20260914-2144-build24-r1-preflight-3834d45/tyrell.dbusing SQLite's backup operation against the live database. - Set the backup to mode 600.
- Did not stop or replace the Build 15 daemon, did not replace the Build 17 app, did not transfer the Build 24 stage, and did not start a guard or canary clock.

Undo and outstanding actions
- This backup is additive and does not require rollback. Retain it through Build 24 canary acceptance and fleet rollout so the preflight database state remains recoverable.
- Do not use the backup to overwrite the live database unless a separately authorized and evidence-backed recovery requires it.
- Explicit runtime-freeze acknowledgment from
claude@rdmbair15m5/dev-a7remains required before any Build 24 transfer, install, or launch. - This Markdown changelog is mirrored to the canonical archive. Apple
