Executable

Is this coffee from one place, or is it a blend?

ALS-COFFEE-1.2-SOURCE-001

This question is asked as a test and produces a result for a real page.

Assertion

single_origin_claim_stated is_stated true

Applicability

applies when
the product is roasted coffee offered to consumers in any format
signal
product_type or title indicates coffee

Accepted evidence

  • product_description — an explicit single-origin claim with a named place at region level or finer e.g. Single origin from one farm in Huila, Colombia.
  • structured_data — the same statement inside the JSON-LD product description
  • product_title — the claim in the product title where the title also names the place

Explicitly insufficient evidence

What does not count, and why. Published because the omission is where a check quietly becomes a claim.

  • "single origin: Ethiopia" or any country-only claim
    A country with dozens of non-comparable growing zones is true and uninformative; the minimum non-misleading content is a place specific enough that a buyer could ask about it.
  • "100% Colombian"
    A national blend of thousands of farms satisfies this exactly; it is a purity claim about a country, not a claim about granularity.
  • a single-origin claim on a page that names two or more regions
    The label and the content contradict each other, and a keyword check passes it because the phrase is present.
  • "direct trade", "relationship coffee", "farm direct"
    These are sourcing-relationship claims routinely substituted for granularity claims, and they say nothing about how many places the coffee came from.
  • "single farm" where the named entity is a washing station
    A station buying cherry from hundreds of smallholders is one site rather than one farm, so the words overstate the granularity by an order of magnitude.
  • "our single origin range" or a collection-level statement
    A statement about the seller's catalogue is not a statement about this product, and the engine cannot tell the two apart.

Conflict rules

  • When the title says single origin and the description names a blend of countries — then record the contradiction; the standard reports that the page disagrees with itself rather than choosing a side precedence: product_description > product_title
  • When the seller publishes its own definition of single origin elsewhere on the site — then a site-level definition does not change what this page states; evidence is read from product surfaces only

What a pass licenses

A pass establishes: That readable product text on this page contains a single-origin phrase, quoted verbatim where a clean sentence exists.

A pass does NOT establish: The granularity of the origin, that a place is named at all, that the claim is not contradicted elsewhere on the page, or that the sentence is about this product rather than the seller's range.

Discrimination

Measured fail rate: 89.0% (89 of 100 adjudicated)

95% interval: 81.4% – 93.7%, against a 15-85% target band (wilson95 vs target band)

Verdict: Undecided — the rate is outside the band but its 95% interval is not — this measurement RAN AND DECIDED NOTHING, which is neither of the other two answers and must never be read as either. The entry stays executable and keeps accruing n.

The measurement ran and decided nothing: the rate is outside the 15-85% band but the 95% interval is not. `indeterminate` is a first-class outcome and must never read as either decision — the entry stays `executable` and keeps accruing n. Recomputed by `standards/coffee/issue_v1_2.ts` from experiments/v3-2/standard_run3.jsonl through the shipped `verdictFor` in standards/discrimination.ts; no re-run, no network, no spend. Cross-checked against experiments/v3-2/discrimination.json and standards/coffee/v1.0/fitness.json.

Authored expectation: no prediction, confidence low. The numeric band this standard used to carry is not published at this grammar version.

Blends are at least as common as single-origin lots in retail coffee, and blends will correctly fail, but the engine's dictionary also matches "single estate" and "single farm" and will pass any sentence containing them regardless of subject. The band is wide because the pass condition is looser than the question.

The numeric fail-rate band this reasoning was authored with is NOT carried at grammar 1.2 and is not reproduced here. Authored bands held 1 of 10 against this category's own sample and every miss was HIGH, so a direction derived from the band would inherit the error that condemned it (SCHEMA.md §9.3 step 3). The band survives in ALS-COFFEE v1.1 (standard_hash f8ec2780f60c38931913e5b6cd37506500c8462709209de7180ba6691d6137e7), which is byte-frozen and still served.

Known gaps

  • "Most cheap versions are made from thin stamped steel." — false_pass
    The comparative veto in subject.ts tolerates exactly one word between "most" and its verb, so two-word noun phrases walk through. The coffee analogue credits a contrast against the seller's own other products.
  • "Love that it's fragrance-free!" — a customer in Portland. — false_pass
    Review quotes credited as the store's statement.

For a shopper

Single origin has no agreed definition, so it can mean one farm or one country, and those are very different purchases. The useful check is whether a place is named at region level or finer, because a country name alone tells you almost nothing about what is in the bag.

For a merchant

State the granularity and the named entity at that level — region and municipality for a regional lot, the farm or estate name for a single-farm lot, or the co-operative and the number of contributing producers for an aggregated lot — rather than the phrase alone.
