# Integration -- story 002, Task 4.1: the hook mode (--staged) checks the
# vectors and resolves over a musl reference preset.
# Requirements: R5.7, R6.2.
#
# Same harness as staged.bats: every test works on a private scratch git
# repository (scratch_repo), never on the checkout. Breakage is planted with
# an atom no repository provides, so every reference preset the hook resolves
# over must FAIL and therefore be named -- which is how this suite observes
# the reference preset set without reading the script's constants.
#
# R6.2 is conditional: if Task 2.4 recorded default/linux/amd64/23.0/musl's
# @system as failing (a story deviation), that preset stays out of the
# reference set and the R6.2 case below is replaced by a skip citing the
# deviation -- never weakened.
#
# Each case resolves one touched layer over the reference presets (about a
# minute or two each; staged.bats budgets 3 minutes for the same shape).
