# Outcome-based tests for check-tessl-latest.sh. Drives the hook against fixture
# manifests via TESSL_LATEST_MANIFEST — no git repo needed, deterministic.
#
# Covers:
#   1. jbaruch/* pinned      -> warns, naming the pinned dep.
#   2. all jbaruch/* latest  -> silent.
#   3. only third-party pins  -> silent (jbaruch/* deps are latest).
#   4. no manifest            -> silent no-op.
#   5. malformed JSON         -> silent no-op, exit 0.
