# Build + RUN the §7 GROUNDING-VECTOR tests (engram_cognition.c): the one decay
# model, the consequence gate, and the stored/derived split. Closed-form
# constructed cases — no server, no store, no network. Pure C11 (stdlib + libm).
# Standalone — NOT folded through elc. Two passes:
#   1. PERF   — optimised (-O2, no sanitizer): the functional gate.
#   2. SAFETY — ASan + UBSan on the same suite.
#
# NEGATIVE CONTROL (invariant §8.6 — no test without one). Every symbol this
# suite exercises (cog_decay_factor, cog_grounding_significant,
# cog_significance_inherent, CogGrounding, CogProvClass) is introduced by the
# change under test, so the suite does not COMPILE against the pre-change source.
# To reproduce:
#     git show origin/dev:lang/runtime/engram_cognition.h > /tmp/pre/engram_cognition.h
#     git show origin/dev:lang/runtime/engram_cognition.c > /tmp/pre/engram_cognition.c
#     cc -I/tmp/pre engram/test/test_grounding_vector.c /tmp/pre/engram_cognition.c ...
#     => error: unknown type name 'CogGrounding'; no binary produced.

# engram_store.c declares emit_log as a WEAK symbol and null-checks it, which is

# (The pre-existing runners in this directory — run_verify_tests.sh among them —
# do not do this and therefore fail to link on macOS. Unrelated to this change.)
