Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- send(req, path, { root }) streams the static file to the HTTP response with correct Content-Type, Content-Length, ETag, Last-Modified, and Accept-Ranges headers
- send(req, path, { root }) returns HTTP 304 Not Modified for conditional GET requests when If-None-Match matches the ETag
- send(req, path, { root }) returns HTTP 206 Partial Content with Content-Range header for Range byte requests
- send(req, path, { root, maxAge }) sets the Cache-Control max-age header accordingly
- send(req, path, { root }).on('headers', fn) invokes headers listener allowing custom response headers before streaming
- send(req, path, { root }) emits an error with status 404 when the requested file does not exist
- send(req, path, { root, dotfiles: 'deny' }) emits an error with status 403 when accessing dotfiles with deny option
