Struct FileMutation 

pub struct FileMutation {
    pub path: String,
    pub tool_id: Option<String>,
    pub operation: Option<String>,
    pub raw_diff: Option<String>,
    pub before: Option<String>,
    pub after: Option<String>,
    pub rename_to: Option<String>,
}

A file mutation resolved at view-construction time. Lives on the Turn that produced it; derive_path projects each entry into a sibling artifact change keyed by path with structural.type == "file.write". tool_id links back to the specific ToolInvocation that caused the mutation when the provider can identify it (codex via patch_apply_end call_id, claude/gemini via tool-input attribution); None when the mutation is attributable only to the turn as a whole (opencode’s snapshot diffs between turns).

Fields

path: String

File path (relative to view.base.working_dir if relative, or file:///absolute).

tool_id: Option<String>

ToolInvocation::id of the tool call that produced this mutation, when the provider can attribute it.

operation: Option<String>

Operation: "add", "update", "delete", or a provider-specific tag.

raw_diff: Option<String>

Unified diff (the canonical perspective).

before: Option<String>

File contents before this mutation (when known).

after: Option<String>

File contents after this mutation (when known).

rename_to: Option<String>

When this mutation is a rename, the new path. Projected to structural.extra.rename_to.
