# evals/relational_inference/v1 — provenance

Independent gold for the one-hop relational-inference DETERMINE capability
(mastery-v2 Step 3). The gold `(predicate, subject, object)` triples are authored by
reading the relational predicate algebra (inverse/converse + symmetric)
**independently** of `generate/determine/determine.py` and
`generate/meaning_graph/relational.py` (INV-25 / INV-27) — the reader/determiner never
produced them.

## cases.jsonl — positive coverage (13)

Each case: told fact(s) → `determine(query)` should assert the entailed relation.

- **8 INVERSE/converse** — both directions of `less_than`/`greater_than`,
  `parent_of`/`child_of`, `left_of`/`right_of`, `before_event`/`after_event`.
- **5 SYMMETRIC** — `sibling_of`, `spouse_of`, `equal_to`, `distinct_from`,
  `adjacent_to`, each told one direction and queried the other.

A refusal here is a COVERAGE miss (counted `refused`), never a wrong.

## refusals.jsonl — confusers that MUST refuse (8)

Transitive (direct + through-inverse), asymmetric self-converse (`less_than`,
`parent_of`), cross-predicate (`sibling_of` ≠ `parent_of`, `greater_than` ≠
`equal_to`), object mismatch, and ungrounded. A `Determined` on any of these is a
wrong=0 breach — the lane test fails loudly.

## Known coverage gap (honest)

`overlaps_event` (symmetric, pack-declared `graph.edge.symmetric`) is **excluded** from
the positive gold: the relational reader requires a copula ("X is _connective_ Y"), but
`overlaps` is a finite verb — "The meeting overlaps the lunch" refuses
(`no_relational_template`) and "is overlaps" is ungrammatical. This is a **reader
surface limitation, not a determination gap** (the symmetric rule would fire if a fact
were stored). A finite-verb relational surface is brief-pack follow-up work.
