I need to brief a teammate on a hard source-spending budget for research agents. What are the two or three facts I should lead with?

> ⚠ Low confidence — 2 sub-claims remain below the evidence threshold within budget. Treat this as provisional.
Here are the facts to lead with when briefing a teammate on a hard source-spending budget for research agents:
1. A hard budget needs a stable unit of account to be meaningful. Autonomous agents need a stable unit of account to reason about budgets, because a volatile token makes a cap like "spend at most $0.05" meaningless minute to minute; dollar stablecoins such as USDC let an agent price expected value against cost in stable terms, which is described as a precondition for rational spending decisions .
2. The budget should be enforced as an all-in ceiling that includes both the service fee and the creator budget. The Keryx buyer client separates quoting, buying and recovering a research job, and the buyer supplies a trusted treasury payee plus an all-in price ceiling that covers both the service fee and the creator budget . Note that this is a first-party engineering note describing the buyer client at a specific commit, not a report of external adoption .
3. The client does not fund the wallet for you, and unused creator reserve is not automatically refunded. The client uses the caller's already-funded wallet and does not automatically fund or deposit for it , and unused creator reserve under the fixed-price package is not an automatic refund .
On the definitional part of your question: the supplied sources do not contain an explicit definition of the term "hard source-spending budget." The closest supported material is the all-in price ceiling covering service fee plus creator budget and the stable-unit-of-account precondition for budget reasoning ; anything beyond that would be inference, so I have not stated it.

Final check — "What is a hard source-spending budget for research agents?": 20% assessed by S2, S3
Final check — "What are the two or three most important facts to lead with …": 20% assessed by S3
Final coverage assessment — The supplied passages describe mechanisms relevant to agent spending (x402 per-request payments, stablecoin unit-of-account budgeting, and Keryx buyer-side price ceilings/recovery), but none defines or directly answers what a 'hard source-spending budget for research agents' is, nor identifies the two or three most important facts to lead with in a briefing on that topic. S1 and S2 provide topical context about agent payments and stable budgeting; S3 provides related but distinct buyer-side price ceiling and recovery facts; S4 is about settlement latency, not budgeting. The requested definition and briefing facts remain missing. The assessment does not establish a complete supported answer for every requested part.
