9proc core becomes a backend of cloud9.fs; engine gains optional features

2026-09-20T04:47:29Z

9proc's own fid table, walk loop and dir-read engine are replaced by cloud9.fs.Server; the tree (static, vars, providers) is served through the engine's Req/Reply contract with node ids that keep the old qid scheme. Providers may answer later by returning error.Again (parked in the engine, retried each step, Tflush -> EINTR); no new files are exposed. Engine (backward compatible, all opt-in via Backend.features / Options): create, remove, wstat, reference accounting for backends that count handles, a salted fid index, name_capacity 0 (names from getattr), Reply.ename for backend-chosen error text, Attr.path/version/atime. Engine-level error strings and the 217-byte msize floor now apply to 9proc; tests updated accordingly. Co-Authored-By: Claude Fable 5.1
