invalid %s lock value

Error message

invalid %s lock value

What it means

selectedSHAEntry: the lock entry's stored value is the empty string, so there is no resolved SHA/digest to pin into a selected entry. The lockfile entry exists but its value is missing.

Solutions

1. Re-resolve the latest entry so a concrete value is stored
2. Regenerate the lockfile — the empty value indicates corruption
3. Validate lock values at load time to catch this earlier
