On 2026-09-18 a Windows leg printed "7925 passed, 0 failed" and "=== All tests passed ===" and still exited 1, while the identical work run through win.sh's other entry exited 0. The status travels ssh -> cmd.exe -> msys2_shell.cmd and that chain loses it. A channel that can turn 0 into 1 can turn 1 into 0, and that direction is a false green: a red Windows leg reported as passing, which is the one thing the local ladder exists to prevent. So the two channels are now split by what each can actually know. The log decides the test outcome — it is written by the runner on the VM and cannot be mangled in transit — and rc only decides what the log cannot see. Green needs zero reported failures AND the completion marker scripts/test.sh prints last, so a leg that stopped early has a summary but no marker and is red. A lost exit status is reported, not obeyed. The logic is a function, vm_verdict(), reachable as `--verdict <log> <rc>`, so tests/test_vm_verdict_contract.sh drives the REAL code with synthetic logs instead of a copy that could drift from it: lost exit status, failures under rc=0, a marker that must not launder failures, failures in a later suite, partial runs, and no summary at all (which keeps its own exit code 90, so "never ran" stays distinguishable from "ran and failed"). Eight cases, wired into scripts/test.sh as step 0y. Signed-off-by: Martin Vogel <martin.vogel.tech@gmail.com>
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 0a–0r) + 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.
Recommended workflows
- 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 withSANITIZE=for a plain build, or use the emulatedwin.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(+soakwhen the change touches memory/daemon paths). - Concurrency-touching change: add
scripts/test.sh --tsanearly — 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.shautomatic;scripts/ci/preflight-docker.sh) andtest-infrastructure/README.md's residuals list cover the knowable differences.
