Gate publishing on a smoke test, and listen to JoltPhysicsC

[jcant0n]

Two problems, one shape.

The CD published unattended. publish-enabled read !inputs.skip-assets-publishing, and a scheduled run has no inputs to negate, so it evaluated true. The monthly cron pushed to nuget.org on its own, and only when the generated API had changed — the moment with the most risk.

Nothing ran the package first. The CD proves it builds. It links nothing and calls nothing, so a package with the wrong natives, or none for a runtime identifier, looks exactly like a good one.

What changes

cd → smoke → publish, chained by needs in a single run. The CD packs with publish-enabled: false; the smoke job installs that exact artifact and drops a sphere onto a floor through the native library; publish starts only if every leg is green.

The test references the package, not the project, so runtimes/ and the native library resolution are part of what is tested. It asserts rather than prints — the sphere must fall, must settle, and must settle on the floor — and caps at 600 steps so a binding that never settles fails rather than hangs.

Five of the ten identifiers. android, iOS and browser-wasm ship in the package and no runner can execute a console app on them; the workflow says so rather than leaving it to be discovered.

And the trigger

repository_dispatch: [upstream-released], sent by JoltPhysicsC when it cuts a release. The cron fired day 1 at 03:00 and the porter runs day 2 at 05:00, so the monthly look happened 26 hours early — a version took two months to arrive rather than one. The cron stays as a safety net.

Verified locally against the published 2026.8.4.12 on win-x64:

  ok    the allocator and job system were created, so the native library loaded
  ok    the physics system was created
  sphere went from y=2.000 to y=0.480 in 48 steps
  ok    the sphere came to rest in 48 steps, so the simulation both ran and settled
  ok    the sphere fell, so gravity was integrated
  ok    it settled on the floor rather than falling through it (y=0.480)
PASS

Same structure merged in Cesium.NET, where the five legs are green in CI.

API gate: additive

Every symbol that existed still exists, unchanged. Nothing that compiled before stops compiling.

_{Enum and constant values are part of the measured surface: a renumbering keeps compiling and sends the wrong number to the driver, so it counts as a removal.}
