# Fork feature map

This is the canonical feature inventory consumed by `scripts/fork-features.mjs`.
Each JSON block is one feature. Keep stable ids, a one-line purpose, Issue/PR
links, exact repository-relative paths and literal, case-insensitive watch keywords.
Empty file arrays mean no new files or no independently owned upstream edits.

`upstreamFiles` assigns every allowlisted path to exactly one primary feature.
`sharedFiles` records other features using that path; all three file arrays take
part in overlap detection. Primary ownership does not imply exclusive behavior.
Some historical allowlist entries (the threads toolkit) are actually fork-new
files; they remain allowlisted and have one owner for compatibility.

Update this map with each fork feature or deletion. The report is a heuristic:
renamed capabilities or different vocabulary still need human review. Keywords
flag possible overlap, not proof of duplication. See [the routine](fork.md#routine)
for per-match decisions and the absorption PR record.
