APP_DEBUG=0 in .env means doctrine.dbal.profiling, which defaults to
%kernel.debug%, was off in tests too, so doctrine.debug_data_holder was never
registered. Every test calling countQueries() errored out — all four N+1
regression tests had been dead for as long as they have existed. Turning
profiling on for when@test brings the harness back.
Three of the four passed immediately. The fourth was a real N+1: the
service-coverage endpoint batch-fetched its ServiceItem entities to avoid one
find() per row, but ServiceItem maps staffMembers as fetch: EAGER, so hydrating
N items fired N extra collection loads and the batch bought nothing. Six
coverage rows cost 11 queries where one row cost 6.
ServiceItemRepository::findUuidsByIds() returns the id => uuid map as a scalar
query, so no entity is hydrated and no eager collection is touched.
Also adds the query-count assertion for next_available_at that could not be
written while the harness was broken. Confirmed it fails against the previous
per-day implementation (40 queries for 2 locations, 113 for 6) and passes now.
Suite: 411 tests, 2 failures — both pre-existing and unrelated
(LowTierFixesTest, PatientWalletSessionSettleTest).
