Release run 30464288732 was blocked by the VirusTotal gate: three linux-amd64
binaries flagged 1/62 by Microsoft's Wacatac.B!ml -- fully stripped binaries
(0 symbols, verified on the exact artifacts), the state that scanned clean in
the two previous cycles. Meanwhile a real Defender endpoint (engine
1.1.26060.3008, signatures 1.455.410.0 updated the same day, RTP on) scans
the identical bytes clean. Four cycles of evidence now say the same thing:
this verdict is an unstable ML decision boundary, not a property of the code,
and no build-side lever moves it durably -- stripping, downloader removal and
metadata changes each "worked" only until a later build flipped it back.
So stop treating the flag as buildable-away and verify it honestly instead:
check-virustotal.sh may downgrade BLOCKED to TOLERATED only when ALL hold:
- pre-release version (-rc./-pre/-alpha/-beta); stable releases never
- every failing file flagged by exactly ONE engine
- that engine is Microsoft and the verdict ends in "!ml" (never a
signature name)
- hash-pinned Defender ENDPOINT evidence is attached to the draft release
(defender-endpoint-verification.txt) proving Microsoft's shipping
product, signature-updated at scan time, reports the exact bytes clean
av-endpoint-verify.sh (new) produces that evidence: downloads the draft
assets, scans them on the local Windows VM endpoint, refuses to attest if
RTP is off or Defender itself detects, uploads the hash-pinned result.
The gate prints the exact command when evidence is missing; re-running the
failed verify job does not rebuild, so the bytes stay fixed.
append-vt-notes.sh (new, extracted from inline YAML per venue-parity) then
renders the release-notes table honestly: a tolerated file reads "1/62 ML
false positive, endpoint-verified clean", never "0 detections".
tests/test_vt_gate_tolerance_contract.sh pins all nine decision directions
against a stubbed VT API and release store -- clean pass, stable-never,
missing/stale/DETECTED evidence, signature-named verdict, non-Microsoft
engine, multi-engine -- so the tolerance provably fails closed.
Also: release.yml gains skip_tests for re-releases of an already test-green
tree (build/smoke/soak/verify always run; lint failures still gate via
!cancelled() && !failure()).

scripts/ci/ — venue plumbing (single implementations)
Support scripts that keep the venues in the SAME shape. Each exists because
the logic used to live inline in workflow YAML or was hand-duplicated between
CI and the local infrastructure — both of which the venue-parity contract
(tests/test_venue_parity_contract.sh) now forbids. Everything here answers
--help (PowerShell: comment-based help, Get-Help <script>).
| script | job | called by |
|---|---|---|
new-protected-temp-root.ps1 |
Create the owner-stamped, inheritance-protected per-user TEMP root the daemon/install suites require (shared /tmp and default runner TEMP grant Authenticated-Users mutation rights, which the trust policy correctly refuses — running there produces security refusals, not signal). -ProtectDir stamps build dirs the same way. |
_test.yml, _soak.yml, vm-run-tests.sh |
clean-test-residue.ps1 |
Sweep cbm-* residue from the Windows VM and assert runner-like free disk (default 14 GB — the GitHub runner's SSD). Long-path \\?\ fallback for the guard suites' adversarial trees; every removal VERIFIED (an earlier version counted attempts and reported 86 swept while 11 GB remained). BLOCKS below the floor: a disk that fills mid-run reads as a product bug. |
win.sh before every build/run |
preflight-docker.sh |
Same idea for Colima/docker: prune runner-unlike residue, assert free space on the filesystem backing the docker data root (not the VM's /). Build cache + named volumes KEPT (the local analogue of actions/cache); --deep drops them. |
test-infrastructure/run.sh |
check-glibc-compat.sh |
Run a linux binary in debian:bullseye (glibc 2.31) — the portable binary must start on old glibc. | _smoke.yml portable legs |
generate-sbom.py |
The release SPDX SBOM (vendored versions reviewable here, diffable by vendoring PRs — was inline YAML). | release.yml |
require-all-green.sh |
The aggregate gate: fail unless every needed job succeeded or legitimately skipped (was inline YAML). | pr.yml ci-ok |
verify-shard-union.sh |
Prove sharded test legs lost nothing: shard count agreement, indices 1..n, identical suite lists, union of slices == full list (was inline YAML). | _test.yml shard-completeness |
check-virustotal.sh |
Release-asset VirusTotal lookups. | release.yml |
