Martin Vogel bdb99d7750 fix(release): stop re-scanning bytes VirusTotal has already scanned
The verify pass submitted every extracted object, selected executables included,
on the stated grounds that "VirusTotal is content-addressed, so identical bytes
return the analysis it already holds instead of re-running 70+ engines".

That is measurably false. On v0.10.5 all EIGHT re-submissions produced a NEW
analysis - same VirusTotal file-id, timestamp 47 minutes later:

    candidate: file-id=2c00f485...  ts=1786795957  (12:12:37Z)
    verify   : file-id=2c00f485...  ts=1786798758  (12:59:18Z)

Re-analysing identical bytes re-rolls a probabilistic classifier, and Microsoft's
ML engine answered differently within that hour, in BOTH directions:

    82750cd1 (linux-amd64)   microsoft-ml -> clean
    6d3c5be6 (darwin-arm64)  clean        -> microsoft-ml

The published notes are generated from the candidate scan, so v0.10.5 shipped a
table calling linux-amd64 flagged when VirusTotal had it clean, and darwin-arm64
clean when VirusTotal was reporting Trojan:Script/Wacatac.B!ml. Every hash in
that table links to the page that contradicted it. Corrected in place after
publication; this removes the cause.

The second scan proved nothing the first did not. Identity is settled by hash
before this step runs: verify-release-selection.py reconciles every published
container to the selected bytes, and checksums.txt binds the same digests
publicly. A re-scan adds no assurance - only another roll.

What still gets scanned is exactly what the candidate pass never saw: install.sh,
install.ps1, LICENSE, THIRD_PARTY_NOTICES.md, the MCPB manifest.json and the
unpacked UI assets. install.sh and install.ps1 are the highest-consequence
non-executable bytes we publish - users pipe them straight into a shell - and
that coverage is untouched. Measured on the v0.10.5 object set: 16 objects in,
8 withheld, 8 still scanned.

The withheld set is recorded as evidence (cbm-virustotal-withheld-v1) naming each
sha256 and pointing at virustotal-candidate-results.tsv, so the published
evidence still accounts for every shipped object.

Fails closed three ways, each with an actionable message: no object matches a
selected sha (the containers do not carry the recorded bytes), everything is
withheld (the surface scan would be a no-op), or the selection names no shas at
all. The zero-match grep is wrapped rather than left to pipefail, because a
guard that aborts silently is not a guard - found by testing the guards rather
than assuming them.

Also drops 8 VirusTotal submissions per release.

scripts/ — the canonical leg entries

The doctrine (enforced, not advisory): a venue may provision a machine; only a canonical leg script may exercise the product. Local CI, PR CI, the dry run and the release all call the SAME files below — venues differ only in host specs, architecture and inputs, never in what a leg does. Platform differences (arm64 sanitizer flags, native Windows behavior, the Linux portable binary) live INSIDE these scripts, once, never per-venue. tests/test_venue_parity_contract.sh (run as Step 0j of every test leg) turns any violation — inline harness logic in a workflow, a bypassed wrapper, a missing --help — into a red build.

Every entry answers --help (authoritative, agent-oriented: modes, env, exit codes) and rejects unknown flags with exit 2 + Please consult --help.

The legs

leg entry what a run gives you
test test.sh DEFAULT = the venue leg: static contracts (Step 0a0r) + CLEAN ASan+UBSan build + all suites via the parallel harness + prod-binary guards. --suites a,b = iteration mode (incremental rebuild, subset, seconds). --tsan = the ThreadSanitizer leg. CLANGARM64 gets CI's trap-UBSan flags automatically.
package wrappers ci/test-package-wrappers.sh Go, npm, and PyPI runtime-set publication/lock suites on the current host. CI runs the same entry on Linux and Windows so both platform lock implementations gate.
build build.sh CLEAN production runtime set (native executable + authenticated integration asset; --with-ui adds one content-addressed UI pack). ccache via env.sh makes repeats fast; CCACHE_COMPILERCHECK=content guarantees a hit is byte-identical to a cold compile — never stale. --version, STATIC=1, BUILD_DIR=.
lint lint.sh clang-tidy + cppcheck + clang-format (+ no-skips policy). --ci = the CI gate set (no clang-tidy). Drives the same make targets as make lint/lint-ci.
smoke (unix) smoke-local.sh Stages a full release fixture, serves it on a kernel-assigned port, runs smoke-test.sh (ALL phases incl. download/install/update E2E) inside a disposable HOME/XDG/TMP sandbox. ui variant makes a missing verified UI pack a FAILURE. CBM_SMOKE_ARTIFACT_DIR = smoke an extracted release artifact verbatim (release mode).
smoke (windows) ../test-infrastructure/vm/vm-smoke.sh Same verified runtime-set contract on the real Windows VM, plus the user-PATH registry guard (prepare/verify/cleanup).
smoke-invariants smoke-invariants.sh Production-path resilience battery (MCP handshake, all tools invocable, malformed-input handling, supervised crash/hang recovery) — no fixture server or install E2E. smoke.yml runs an explicitly seam-enabled build on the WIDEST source matrix; release artifacts remain seam-free and use the release-shaped smoke legs above.
soak soak-legs.sh The release-gating soak SEQUENCE: quick then query-leak (the #581 detector — never reindexes, so RSS growth = query-path leak), each guarded by a completion-summary check. --legs quick for the ASan single-leg variant. Duration is per leg.

Internal harnesses — never called directly by a venue (the contract forbids it): smoke-test.sh (phases; wrappers provide fixture server + sandbox), soak-test.sh (one soak run; soak-legs.sh provides the sequence + guards), run-tests-parallel.sh (reached through test.sh).

Conventions

  • Exit codes: 0 = pass · 2 = usage error · 90 = guard (a run died without its completion summary — never counts as green) · anything else = the leg's real failure.
  • Iteration is a flag, not a side-tool: the fast paths (--suites, --legs) are modes of the SAME entry the gates run, so a dev loop can never drift from the venue behaviour.
  • Env sandboxing: the smoke wrappers neutralize every agent-config destination override; a smoke can never scribble on your real config.
  • Iterating on a change: scripts/test.sh --suites <suite> (seconds, incremental, same ASan+UBSan flags as the gate). List suites: build/c/test-runner --list-suites. Debugging a Windows-on-ARM trap: re-run with SANITIZE= for a plain build, or use the emulated win.sh ubsan-* pair for full diagnostics.
  • Before any push (the 3-OS ladder): scripts/test.sh (macOS, full) → ./test-infrastructure/run.sh full (Linux + TSan + smoke) → test-infrastructure/vm/win.sh test-par + guards + smoke-install (+ soak when the change touches memory/daemon paths).
  • Concurrency-touching change: add scripts/test.sh --tsan early — the same leg CI gates on.
  • Release-shaped verification: CBM_SMOKE_ARTIFACT_DIR=<extracted artifact> scripts/smoke-local.sh <binary> [ui] smokes exactly what would ship.
  • A leg is red in CI but green locally: first suspect environment shape, not code — the preflights (win.sh automatic; scripts/ci/preflight-docker.sh) and test-infrastructure/README.md's residuals list cover the knowable differences.
