- admin-protected client config (flag > AGENT_LIB_CONFIG > platform default), token used for basic auth only, redacted from all errors and files - work-repo pull via go-git (bare cache clone + fetch, remote re-pointed on config change), clean failure keeps previous state - inventory: own items + external areas from lockfile; MCP inventoried but never deployed - manifest v1 records name/type/origin/revision/content-hash per item, deterministic bytes; folder hashes over sorted relpath+filehash lines so tree and disk hashes agree - shared deploy package (atomic temp+rename, exec-bit preserving) now backs both curator materialization and client deployment - sync validates and hashes everything before the first mutation; second run is a byte-level no-op
