I3667 — A run that would fall through to metered billing while a grant is held, or cross a declared cap, is told before it starts

!CANCELLED wave 4 · p3 · implementation profile · parallel safe

Part of every-model-call-is-paid-from-a-declared-source — How a model call Majordomus starts can be paid is declared by the vendor with evidence, and each call names the source it was declared to draw on.

Objective

Before the economics runner or an execution starts a model client, compare the route's source (I3662) with the owner's holdings and caps (I3661): tell the caller when the route would draw on a metered source while a credit grant is held, or when observed spend (I3666) already meets a declared cap, naming the source, the cap and the figure's class; refuse only where the repository policy declares refuse, through the same mechanism as I3295's over-budget telling.

Why

The point of claiming the grant is that agents run on it and not on the owner's card. Without a check before the run, a missing credential silently moves headless work onto metered billing; with no observed spend, a cap can only be judged on what was observed, never on an estimate.

Current state

Nothing checks funding before a run; I3295 plans over-budget telling for token budgets.

Desired state

Falling through to metered, or meeting a cap, is told before the run and refused only by declared policy.

Scope

• apps/majordomus-cli/src/economics
• apps/majordomus-cli/src/execution
• .ai/repo/policy.yaml

Dependencies

• I3662!CANCELLED models.route names the funding source a route would draw on, as an inference with its basis, in the declared source order
• I3666!CANCELLED Spend against a funding source is observed from a named vendor seam or recorded absent, and no balance is derived from a price
• I3295✕BLOCKED A task declared over its token budget is told so, and refused only where policy says refuse

Acceptance criteria

• A held grant with its credential unset and a metered credential set: the run is told it would draw on metered
• A cap with spend absent is reported as not judgeable, never as within the cap (test)
• With policy refuse, the run does not start and the refusal names the source and the cap

Validation

• cargo test --manifest-path apps/majordomus-cli/Cargo.toml --test economics

Evidence required

• test_falling_through_to_metered_is_told

Evidence

None recorded. Every token above needs a command or an artifact behind it before this issue can be completed; narrative is refused.

Completion report

Cancelled 2026-10-21 on feature/intent-funding-sources by the plan's critique (finding metered-fallthrough-presupposes-separate-credentials): the credit grant and metered billing share ANTHROPIC_API_KEY, so a run 'falling through to metered' is not a state Majordomus can see, and with spend absent for an individual account a cap could only ever read not judgeable. Reopen with a per-source credential split or a spend seam, each with vendor evidence.

Those three fields, the evidence above and the state of the dependencies are all the status is made of. There is no status field to disagree with them.
