Module selection 

Account selection: which account serves a session the gateway has no binding for.

The walk is the org’s accounts list then fallback_accounts, filtered by declared models: the first account whose models list includes the requested model wins. Within the surviving set the first account in walk order wins, with saturation demoting an account to a later tier: ready beats saturated, and a Bailed account is the last resort (its 429 hit the usage probe, not inference).

Structs

OrgPin

An org’s walk order: the primary pin, then fallbacks.

Enums

SelectionError

Why no account was selected. Loud by design: a silent fallback would route a session to an account its model cannot use.

Functions

declares 🔒

true when the account serves model, by declaration or alias.

select_account

Pick the account for model out of org’s walk order: the first account whose declared models include the model. Ready accounts beat saturated ones, and Bailed accounts are the last resort. A retired account - one a reload removed - is never offered.
