Strand Migrate
Usage
Validate a known Strand header layout without assuming migrations exist.
Operator workflow
Use this tool only for its current header check. Preserve a backup and identify the intended Strand directory before opening it; this command has no backup, dry-run or migration-plan mode.
From an authorized source checkout, build the strand-migrate package in your approved build environment, then run the resulting strand-migrate binary with that directory as its sole argument. The success message means the checked headers satisfied the implemented key-length condition. It does not certify every block payload, a schema upgrade, or recoverability.
