States, consistency and recovery

State path: IDLE → VALIDATING → VALIDATION_ERROR → AUTHENTICATION_OR_AUTHORIZATION_REQUIRED → PROCESSING → CONFLICT_OR_EXPIRED → UNAVAILABLE_OR_OFFLINE → RATE_LIMITED → SERVER_ERROR → RETRYING → AUTHORITATIVE_SUCCESS_OR_RECOVERY → NOT_FOUND
Reads: server command preconditions
Writes: Firebase Auth SDK mutation; Firebase Auth remains authoritative
Transaction: Firebase Auth SDK authority
Idempotency: provider/Firebase defined
Concurrency: provider or Firebase atomicity
Retry/replay: do not blindly replay
Rate limits: The typed port does not ratify a public numeric quota; enforcement may be stricter. Honor RATE_LIMITED and any retry-after value returned by the server.
Audit: server audit/outbox where the command is consequential

These references prove export, wrapper or protocol behavior only. They are not counted as complete operation semantics.

Example availability

UNRESOLVED_WIRE_SCHEMA: No exact public wire invocation is established by the typed port; use the owning Firebase SDK or rules adapter after its producer contract is verified.

Common integration contract

Sandbox and Production are isolated

Run examples only in a governed sandbox or local emulator. Sandbox identities, App Check tokens, payment fixtures and data do not grant Production access. The typed ports do not ratify a public numeric quota; enforcement may be stricter. Honor RATE_LIMITED and the server's retry-after value.

Authentication and authorization

Firebase Auth proves identity. App Check proves the approved app where a callable requires it. Roles, organization membership, requester identity and resource ownership are derived and rechecked by the server.

Authentication guide

Errors and recovery

Stable error codes distinguish validation, denial, conflict, expiry, authority pending, rate limiting and temporary unavailability. Never infer success from an HTTP redirect or a browser state.

Error catalogue

Idempotency, concurrency and retry

Reuse an idempotency key only for an identical retry. A new intent needs a new key. Preserve version preconditions and reload after a conflict.

Retry guidance

Changes and escalation

Check compatibility before adopting a new contract version. Review the changelog, service status and support guidance before retrying a persistent failure.

Changelog Service status Developer support

Common failure families
Family	Client decision
Authentication / authorization	Refresh or step up only when instructed; do not retry a denial unchanged.
Validation / conflict / expiry	Correct or reload state, then obtain confirmation for a new intent.
Rate limited / unavailable	Honor retry-after and use bounded backoff; inspect service status.
Unknown / server	Fail closed and escalate with a privacy-safe correlation id.

Executable network examples are published only when the exact wire schema is producer-proven. Check the selected operation's example-availability status; an unresolved schema is a release blocker, not permission to guess.
