trailing bytes in encoded script record. malformed

Error message

trailing bytes in encoded script record. malformed

What it means

Decoder guard in the scripts store's record decoding: after parsing name, description, shebang, tags, and script body of a v0 script record, unconsumed bytes remain. A well-formed record ends exactly at its last field, so trailing bytes signal a malformed record — corruption, truncation, or an encoder/decoder format mismatch.

Solutions

1. Delete and re-create the affected script record, then re-sync the scripts store
2. Check for disk corruption or interrupted sync writes
3. Verify all clients use a matching Atuin version
