Struct PatchParams 

pub struct PatchParams {
    pub path: String,
    pub ops: Vec<AnchorOp>,
    pub expected_md5: Option<String>,
    pub backup: bool,
    pub backup_path: Option<String>,
    pub evidence: bool,
    pub diff_max_lines: usize,
    pub allow_lossy_utf8: bool,
    pub validate_syntax: bool,
}

Parameters for an anchored patch: the target file and one or more anchored edit ops, plus optional guards/evidence (mirrors EditParams where it makes sense so the registered wrapper stays uniform).

Fields

path: String

ops: Vec<AnchorOp>

expected_md5: Option<String>

Optional whole-file preimage guard (BLAKE3 hex, as printed by ctx_edit’s postimage: line). When set, the edit fails if the file’s hash differs.

backup: bool

backup_path: Option<String>

evidence: bool

diff_max_lines: usize

allow_lossy_utf8: bool

validate_syntax: bool

Post-edit tree-sitter gate (#1008): reject a write that turns a cleanly parsing file into a broken one. Default true; set false to override (e.g. intentionally writing an incomplete snippet).
