token streaming, the accumulate-and-reconcile consumer pattern, and full-duplex live streaming for voice
Consuming output as it is produced: partial events and token streaming, the accumulate-and-reconcile consumer pattern, and bidi/live streaming for voice and interactive UIs.
How a workflow graph forms a cycle: two executors feed each other until one yields an output — the workflow analogue of a while-loop.
A workflow graph is not a DAG: two edges form a GuessNumber to Judge cycle that runs a binary search and exits only when Judge yields an output. The while-loop analogue.
Wrap a typed Go function as a tool, let the model call it, and compose whole agents as tools.
Wrap a typed Go function as a tool with functool.MustNew, let the model call it, and compose whole agents as tools with agenttool.New.

Why fintechs keep a transaction-grain subledger separate from the accounting general ledger, and how the posting, aggregation, and tie-out actually work.
Why fintechs keep a high-volume subledger separate from the GL, posting rules, summarization/aggregation, and period-close handoff.
Model variable recurring payments and metered/subscription billing with proration, treating the mandate — not the retry loop — as the object that actually has state.
Model variable recurring payments and metered/subscription billing with proration, distinct from retry logic.
From BIN and program configuration through card production, HSM-backed PIN generation, and the real-time authorization controls engine.
Build the issuer side: BIN/program config, card production, PIN generation via HSM, and real-time authorization controls.
One reference model of every party in a card transaction — cardholder, merchant, gateway, acquirer/processor, scheme, and issuer — and the settlement path that moves the real money back the other way.
One reference map of who does what in a card payment: cardholder, merchant, gateway, acquirer/processor, scheme, issuer, and the settlement return path.
