compile_premises emitted every chain in a family, and read_verb_argument
refuses past MAX_PREMISE_SENTENCES=16 — a 17-chain family answered nothing
at all, which meant no curriculum band could ever earn a license regardless
of corpus size (ADR-0264 §4.1).
compile_premises now accepts an optional query=(subject, connective, obj)
and scopes compilation to it: the default is term incidence (chains whose
subject or object is one of the query's two terms), narrowing further to
the exact query-atom rows only if term incidence would still exceed the
cap. Both scopes are verdict-identical to full-family compilation, because
every compiled premise mints one independent propositional atom that no
other atom in the argument can constrain (ADR-0264 R5) — verified over all
8,520 routable questions in the four served domains: 0 mismatches, 4,494
empty scopes all confirmed `unknown` under full-family compilation.
decide_curriculum_question (the only production caller) now distinguishes
an empty SCOPE (open-world UNKNOWN, R6) from an empty FAMILY (the existing
`empty_curriculum` refusal) — getting this wrong would have flipped most
of the question space from unknown to declined. premise_count keeps
reporting family size for the user-visible surface (R7); the compiled
scope size is carried separately on a new `scope_size` field.
Physics gold is unchanged: entailed 14 / unknown 12 / declined 6, lane
report byte-identical, SHA pin unchanged.
[Verification]: smoke suite 569 passed (140.5s), deductive suite 291
passed (50.5s, +6 new tests in tests/test_curriculum_serve.py), warmed_session
lane 10 passed (146.0s), curriculum_serve lane wrong=0 (n=32), all on
canonical Python 3.12.13 with uv sync --locked.
