One ordered mutation of an existing path-independent file record.

Variants

ReplaceRecord

Replaces one authenticated file record without changing its live bindings. The current identity and link count remain authoritative.

Fields

record: FileRecord

Complete replacement record for the same file identity and kind.

SetMetadata

Replaces the complete canonical metadata object.

Fields

metadata: ObjectId

Authenticated metadata object.

Write

Replaces one logical byte interval with authenticated content.

Fields

offset: u64

Inclusive destination offset.

length: u64

Positive byte count.

content: ObjectId

Authenticated blob containing source bytes.

content_offset: u64

Inclusive source offset in content.

ValidateRegular

Validates that the existing identity is a regular file without changing it.

Resize

Changes logical file length while preserving sparse semantics.

Fields

logical_bytes: u64

New logical byte length.

ZeroRange

Replaces a range with a hole or physically allocated zeros.

Fields

offset: u64

Inclusive logical offset.

length: u64

Positive byte count.

allocated: bool

Preserve physical allocation instead of punching a hole.

extend: bool

Whether the replacement may extend logical file length.

Preallocate

Allocates sparse holes without replacing existing content.

Fields

offset: u64

Inclusive logical offset.

length: u64

Positive byte count.

keep_size: bool

Preserve logical file length.
