Martin Vogel 39e02544cc fix(smoke): UI presence is the caller's claim, not every lane's assumption
Making REQUIRE_UI unconditional broke all three pr-smoke legs:

  FAIL 15a: SMOKE_REQUIRE_UI=1 but this binary serves no embedded UI assets

The PR lane runs scripts/build.sh WITHOUT --with-ui on purpose, so an npm
frontend build does not land on every product PR. Demanding embedded assets
there asserts a property that lane deliberately does not produce.

The guard still exists where it means something: scripts/ci/smoke-artifact.sh
builds --with-ui, packages the real archive and smokes the EXTRACTED result, so
it exports SMOKE_REQUIRE_UI=1 and a frontend-less binary fails there. That is
the lane whose whole job is release fidelity.

Deliberately NOT fixed by adding --with-ui to pr.yml: that would put `npm ci &&
npm run build` on three runners for every product PR to re-prove something the
dry-run and release lanes already gate. PR CI cost is not free and this branch
should not quietly raise it.

test-infrastructure/ — the local venues

The local half of the 3-OS CI ladder. Every leg here runs the SAME canonical scripts CI runs (scripts/test.sh, build.sh, smoke-local.sh, soak-legs.sh, vm-smoke.sh — see scripts/README.md); this directory only provisions containers and the Windows VM. The venue-parity contract (tests/test_venue_parity_contract.sh, Step 0j of every test leg) fails the build if a venue grows its own harness logic — here or in the workflows.

Entry points

venue entry notes
Linux (arm64 + amd64) + cross-compile ./run.sh <leg> (--help for the leg list) Colima only — Docker Desktop is broken on this machine. A clean-disk preflight (scripts/ci/preflight-docker.sh) runs before every leg: GitHub runners are ephemeral with a known-free 14 GB disk, so the long-lived VM is swept back to that shape first.
Real Windows (UTM ARM64 VM) vm/win.sh <command> (win.sh help) Same preflight idea (scripts/ci/clean-test-residue.ps1), plus CI's protected per-user TEMP root. Wine (run.sh windows) is a compile check only — never a substitute for the VM.
macOS run the canonical scripts natively scripts/test.sh, scripts/build.sh, scripts/smoke-local.sh …

The ladder (before any push)

  1. scripts/test.sh — macOS native (or --suites … while iterating)
  2. ./test-infrastructure/run.sh full — Linux arm64 test/build/TSan/smoke/portable + mingw cross-compile (+ amd64, soak-linux as needed)
  3. vm/win.sh test-par · guards · smoke-install · soak — the real-Windows legs

Infra unavailable = a run blocker to escalate — never a silent bypass.

Fidelity guarantees (what makes local predictive of CI)

  • Same scripts, same sequence, same flags — platform specifics (e.g. the CLANGARM64 trap-UBSan default) live inside the canonical entries, applied identically everywhere.
  • Same environment shape — protected TEMP roots, sandboxed smoke, clean builds with the content-verified ccache (a hit is byte-identical to a cold compile; caches only accelerate, never change results).
  • Same starting disk — preflights sweep residue and BLOCK below the runner's 14 GB floor (a quietly full disk fails inside install paths and masquerades as a product bug).
  • Known, deliberate residuals — runner physics (4 vCPU vs local cores, shared tenancy), Defender ON in the VM vs OFF on GitHub runners, no TSan on Windows anywhere, no ASan runtime on native ARM64 Windows (trap-UBSan + PageHeap stand in).
