api/remotes owns the allowlist and its type projection; type-meta owns the shape predicate, the selection seat, and the internal remote/host-event carrier signal; api/gateway's Client half turns that signal into $on callbacks through a private dispatch. apiproxy forwards each allowlisted emission verbatim in one host/remote-event frame, registered ahead of the derived invalidation frames so frame order is unchanged, and drops the three per-event variants it replaces. Owner packages move their Events declarations into client-safe ./types exports, so a consumer's listener signature is the Host's own declaration.
credentials/ — credential references
English | 中文
The credential capability family separates reference resolution from its provider:
| Package | Role | ctx key |
|---|---|---|
credentials/ |
Credential-reference seam | ctx.credentials |
credentials-local/ |
Environment and local-file provider | registers ctx.credentials |
Configuration carries references, not secret values. Consumers resolve those references at their operation boundary; the child READMEs own mutation, precedence, and storage semantics.
The subsystem reference — CredentialRef, per-operation resolution, UI-safe CredentialInfo, provider layers — is docs/subsystems/credentials.md.
