=== A. release registry gate names and tasks ===
$ python3 -c "import json;d=json.load(open(\"config/jpa/release-registry.json\"));print(len(d[\"gates\"]));[print(g[\"name\"],g[\"task\"],g[\"blocking\"]) for g in d[\"gates\"]]"

=== B. is the pool lane a registered gate? ===
$ grep -n -i pool config/jpa/release-registry.json
exit=1

$ grep -n -i pool ../docs/jpa/support-matrix.md
exit=1

$ grep -n -i pool adapter/outbound/persistence-jpa/src/testkit/java/dev/caskeleton/adapter/outbound/persistence/testkit/release/JpaReleaseGate.java

=== C. where the pool lane is wired ===
$ grep -n jpaPlatformPoolContractTest adapter/outbound/persistence-jpa/build.gradle

=== D. what the lane files actually assert ===

=== E. does any lane assertion read a non-zero pending count from a real pool? ===
$ grep -rn "getThreadsAwaitingConnection\|pending()\|saturated()" adapter/outbound/persistence-jpa/src/jpaPlatformPerformanceTest

exit=0

=== F. nightly workflow claim text ===
$ sed -n 122,135p ../.github/workflows/jpa-nightly.yml
      - name: Verify pool saturation and REQUIRES_NEW connection behaviour
        working-directory: src
        # A behaviour contract, not a measurement. This step used to switch assertions off with an
        # explicit property and call the result a certification, so the only threshold it ever
        # asserted was that thresholds were not being asserted. What
        # it checks now — that REQUIRES_NEW needs two connections per concurrent thread, that a
        # saturated pool reports its pending count, that a caller waits rather than proceeding
        # without a connection — is true on any runner, so there is nothing to switch off.
