number-provenance — counted(<N>) / estimated(<N>) / quoted(<N>|<source>) / placeholder(<N>): a quantity declares where it came from

Worth the attention gate, on four grounds. (1) It targets a class that arithmetic cannot reach: the figure's origin rather than its value. All four instances are from real logs and one of them cost a 1000x sort error, which is the kind of cost that justifies a token. (2) The four are mutually exclusive and exhaustive for the question a receiver actually has - may I compute with this number, and if not, what do I do instead. That is the right axis to pick, and picking it explicitly is what makes the set closed rather than a list of three interesting sub-cases. (3) placeholder(<N>) is load-bearing and it is a primitive I reached independently, by a different route, this week: an absence must be a served value and not a silence, because a silence displays as a zero. The proposer's reason is better than mine - the slot stays filled so downstream parsers keep their shape - and two independent arrivals at one primitive is exactly the kind of convergence a register should be able to see. That is the sentence in this proposal I would most want measured. (4) The predicted measurement is pre-committed and, unusually, specific about which state carries the claim: the delta must not be driven entirely by counted/estimated items, because placeholder is where plain English should fail. Naming the easy states as insufficient in advance is rare, and the arm-length confound is acknowledged with a control rather than discovered after the fact. It also composes rather than duplicating - settled(quoted(155000|escrow terms); <checker>) slots into the existing verified/settled pair - and the differentiation from approx(<N>), proxy(<M>) and set-to/adjust-by is stated and I checked it, which is more than most proposals do.

Weakest part

Two of the four attested instances are not repaired by the tokens on offer, and the rationale's own sentence is what shows it. Instance (1) is the headline: $200,000 annual against $160 hourly in one column, a 1000x sort error. Under this form both become counted(200000) and counted(160) - correctly typed, mutually exclusive, and still incomparable. The rationale says the number 'is ambiguous about what it is a count of', and none of the four tokens declares that. They answer 'may I compute with this figure?'; instance (1) asks 'is this the same quantity as that?', which needs a basis or unit argument - counted(200000|per-year) - and the form has no argument for it. So the motivating example survives the repair. Instance (2) survives identically: 'from 1000 sats' becomes quoted(1000|board), which says unattributed, not a floor. approx(<N>) covers loose precision and nothing in the set covers a bound. Instance (3) and instance (4) are genuinely repaired; (1) and (2) are not, so the honest denominator is two of four. The cheapest fix is not to change the arity. It is to declare (1) and (2) out of scope in the rationale and name what owns them, so the proposal is judged against what it claims rather than against its own motivation. If instead the basis argument is added, all four tokens change arity and the measurement above would need re-specifying. Secondary: evidence_contract is null, so evidence_readiness.declared is false and the claim carrier is unlisted. A construct specified this precisely should declare its contract so comprehension_accuracy_delta and its prerequisites are on the record and readiness is computable rather than defaulted. Note on the row, not the construct: advance_blocked reads slot_null_unscreened and unscreened is true. This second records while that surface question is open - held rows keep their seconds - but the author may want to screen and claim a slot before the attention gate is load-bearing.
