From 094929fddcb8aaa2e9bc62798902ce59b868d97e Mon Sep 17 00:00:00 2001 From: Martin Vogel Date: Thu, 13 Aug 2026 23:03:38 +0200 Subject: [PATCH 2/6] fix(ci): bind the VirusTotal verdict to the bytes, not to the analysis id MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The dry-run for this branch (run 31729540899) failed in `select-package`, the new job, after every build had completed and before smoke — the exact shape of failure that would have taken a release down: BLOCKED: VirusTotal response analysis id does not match the submitted analysis: objects/70fbbc37... That object is the linux-arm64 UNSTRIPPED candidate, 295,476,856 bytes. VirusTotal is content-addressed, and for bytes it already holds it may answer with its own canonical analysis rather than the one this upload created. A large release binary is exactly the artifact most likely to be already on file, so requiring the ids to be equal would have recurred on most releases rather than being a one-off. The equality check was guarding the right idea at the wrong level. What has to hold is that a verdict describes THESE bytes, and parse_completed already enforces that a few lines below against meta.file_info.sha256 and file_info.size — a strictly stronger binding than the id. It is also what keeps a tuple's two candidates apart: stripped and unstripped differ in hash by construction (70fbbc37... vs 28b3890f... on linux-arm64), so neither can be read as the other whatever ids VirusTotal hands out. The wrong-hash and wrong-size contract cases pin that and still block. The property deliberately given up is freshness: an older cached analysis of identical bytes is now accepted. For identical bytes that is the same content risk, and it buys a gate that is deterministic instead of one that fails whenever VirusTotal recognises our own binary. The submitted id is still recorded in the results manifest as evidence. The selection policy is unchanged and needs no change: stripped clean ships stripped; stripped microsoft-ml with a clean unstripped ships the clean one; both microsoft-ml ships stripped; a hard verdict on either sibling still blocks the release for analysis. Contract test updated to assert the passing direction, and revert-checked: with the fix reverted it fails with the production message, with it applied it passes.

It was classified "hard" — the same bucket as a real malware verdict — purely because 48 engines answered instead of 50. Its own sibling scanned clean with 66. How many engines return a decisive result is VirusTotal fleet availability on the day, not a property of our binary. These artifacts are ~300 MB and many engines skip or time out at that size, so the count sits near the floor and moves run to run: on this run one object landed at 48 and the other fifteen spread 59-68. A floor there makes shipping a lottery decided by someone else's infrastructure, which is exactly what our CI-determinism rule forbids, and it is not something we can influence by fixing anything on our side. Classification now depends only on what engines FOUND: hard - two or more engines, any non-Microsoft engine, any label that is not `!ml`, or anything suspicious. Still blocks the release. microsoft-ml- exactly one Microsoft `!ml`. Tolerated and disclosed. clean - nothing flagged. The decisive-engine count is still recorded per candidate in the results manifest and printed as a NOTE when it is below the reference value, so the evidence is unchanged; only its power to block is gone. The selector keeps rejecting an incoherent response (total < completed). Public claims updated to match in README.md, SECURITY.md and docs/index.html — all three promised "at least 50 decisive engines" as a publication requirement, which would no longer have been true. Contract test updated: a clean verdict now stands regardless of engine count, and the below-reference NOTE must still be reported.

Across the eight targets the stripped and unstripped candidates of the SAME linker output disagreed on four, and in both directions: linux-amd64 stripped microsoft-ml unstripped clean darwin-arm64 stripped clean unstripped microsoft-ml linux-arm64 stripped clean unstripped microsoft-ml If the classifier were keying on something intrinsic to our code the siblings would agree; they do not. So each variant is close to an independent draw, and 5 of 16 candidates drew the flag. Two draws is not always enough. On that run linux-amd64-portable came back microsoft-ml on BOTH candidates, leaving no clean binary to ship for that target. A third independent draw at a ~31% observed per-candidate hit rate takes the both/all-flagged case from roughly 1-in-10 per target to roughly 1-in-30. The third candidate is `--strip-debug` (Apple: `-S`): debug information removed, symbol table kept. Behaviourally identical to the other two — same linker output, only metadata differs — but a distinct byte image, which is all VirusTotal needs to scan it as its own file. Verified on the real v0.10.4 candidates: linux-amd64 gives three distinct hashes (294,634,656 / 294,623,208 / 293,746,096 bytes) and darwin-arm64 likewise, with the ad-hoc signature verifying after strip. Selection is unchanged in spirit and now ordered: smallest artifact first (stripped, debug-stripped, unstripped), take the first CLEAN one, and only if every candidate drew the tolerated verdict ship the smallest flagged one. A hard verdict on any candidate still blocks the release before selection. Cost is 24 objects per release instead of 16. Derivation enforces that all three hashes differ — identical candidates would be one draw wearing three hats, and the selector would believe it had alternatives it does not have. Public claims in README, SECURITY.md and docs/index.html updated from "both stripped and unstripped" to the three candidates. All three release contract tests pass, including the native derivation test which exercises the real strip and codesign path on this host.

charset=UTF-8 Content-Transfer-Encoding: 8bit Two things, both found by the dry-run and by sweeping what it exposed. 1. The three-candidate change was incomplete. The dry-run failed at stage-release-candidates.py, which carries its OWN copy of the transform validation that the previous commit only fixed in the selector: stage-release-candidates: candidate linux-amd64/debug-stripped has invalid transform: 'strip-debug' Sweeping for that assumption found it in six places, not two: stage-release-candidates.py, select-release-candidates.py, verify-release-selection.py, append-vt-notes.sh and two contract-test fixtures — as hardcoded 16s, `len(TARGETS) * 2`, two-entry VARIANTS tuples and two-key truth tables. All are now derived from len(VARIANTS). Field prefixes needed care: the variant NAME keeps its hyphen because it is the on-disk directory, while the evidence columns use underscores, so `debug-stripped` reads `debug_stripped_sha256`. Every lookup now goes through an explicit FIELD_KEY map instead of interpolating the variant directly. The selection contract test now covers the truth table EXHAUSTIVELY: three variants x two tolerated classifications is exactly eight combinations, and there are exactly eight targets, so every case is exercised once. 2. Full-surface VirusTotal scanning is restored. This PR had moved scanning upstream to the candidates and deleted the post-package pass, which silently narrowed coverage from everything we ship to executables only. The 42 runtime files across the 14 containers — install.sh, install.ps1, LICENSE, THIRD_PARTY_NOTICES.md, the MCPB manifest.json and the unpacked UI assets — were still extracted, structurally verified and strings-audited, but no longer scanned at all. install.sh and install.ps1 are the highest-consequence non-executable bytes we publish; users pipe them straight into a shell. The verify job scans every extracted object again, under the same policy. Re-submitting the selected executables alongside them is close to free because VirusTotal is content-addressed and answers for identical bytes from its own record — the same property that made the analysis-id equality check untenable two commits ago. The gate-chain contract asserted the opposite ("duplicate post-package VirusTotal path remains"). That assertion is inverted: the pass is required, and it is not a duplicate, since it covers a strictly larger set. README and SECURITY.md updated from "archive containers are checksummed rather than redundantly rescanned" to state the full covered surface. All five release/VT contract tests pass.
