# (label, query) pairs fed to `recall`. Chosen to span neighbourhood sizes — the
# real cost driver — from a likely-leaf to a known hub. APTA and CapMetro are the
# subjects the maintainer configured; "echo" and "operator preferences" are dense hubs
# that stress the 1-hop expansion (the read_many fan-out 1.1.0 accelerated).

# --- §4.3 fuzzy-resolve correctness table (1.2.0) -----------------------------
# Each case: mention, expected behaviour. `expect_slug` is the canonical slug an
# exact/alias/fuzzy match should land on (None = no entity expected). `expect`
# is the classifier:
#   "exact"      -> resolve returns an entity whose slug == expect_slug
#   "candidates" -> no exact hit, but fuzzy_candidates surfaces expect_slug
#                   (the 1.2.0 anti-duplicate guard — a near-miss must NOT resolve
#                    to nothing and silently spawn a new note)
#   "miss"       -> neither; genuinely unknown
# Tune expect_slug to the live vault; unknowns are reported as INFO, not failures.
# NOTE: the subject/slug values below are neutral placeholders. The maintainer
# should point these fixtures at dense hubs that actually exist in their own
# vault, otherwise the resolve cases will report INFO misses rather than hits.
