Splice write
Status: open/active · Aliases: span-level write
Definition
Section titled “Definition”A surgical, programmatic write: replace exactly the byte span of the edited node and never touch any other byte, so fidelity of untouched content is guaranteed by construction rather than by careful re-serialization. Span-level, not line-level — a wikilink or table cell is a mid-line span. Requires a TM-0018-byte-accurate-parser and fresh-parse addressing (never stored line numbers). The only legal programmatic write to human-edited files; CAS-guarded and validation-gated.
