Martin Vogel 674a731fcc ci(test-impact): give the engine full history; publish maps with an incomplete suite
The test-impact engine certifies the history it diffs and refuses a shallow
clone ("Graft or shallow state prevents history certification"). The shadow
job, the gate-mode select-tests job and the main-branch producer all checked
out with fetch-depth 2. So every shadow answer since #2458 was run_all:
GIT_UNAVAILABLE, then POLICY_UNAVAILABLE, because the merge base's
.codebase-memory.json is read through the same git facts. That was 24 of 24
measured PR runs. All three jobs now check out full history (about 400 MiB,
these jobs only).

The producer never published a bundle either. coverage-map.py exits 1 when a
suite fails under coverage: the map is still written and that suite's tests
are incomplete. test-impact-publish.sh ran it under set -e, so the publish
aborted. The failing suite was test_impact_git. Its hostile-diff probe
re-enters the runner as a child, which inherited CBM_TEST_COVERAGE_DIR,
started a coverage run of its own, and refused the per-test LLVM_PROFILE_FILE
it inherits.

Two changes:
- The probe now clears CBM_TEST_COVERAGE_DIR, as it already clears
  CBM_TEST_ONLY_FILE. The child's profile then goes to the spawning test, like
  any other child process.
- publish treats exit 1 as a written, conservative map (incomplete tests run
  whole), with a warning that names the suite. It fails only on exit 2.

Proof:
- Depth-2 clone at f9ce3865: test-impact select answers run_all
  [GIT_UNAVAILABLE, POLICY_UNAVAILABLE] with "Graft or shallow state ...", as
  in CI. Same commit with full history: graph certified, run_all
  [RUNNER_REACHED] (the change reaches the runner's main).
- Coverage runner (Homebrew LLVM, macOS), test_impact_git: before, 43 passed
  and 2 failed ("a coverage run starts with LLVM_PROFILE_FILE=/dev/null");
  after, 45 passed. coverage-map.py --suite test_impact_git: 45 tests,
  0 incomplete, exit 0.

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. --contracts-only = the static contract steps alone (PR CI's contracts job for docs-only and non-product changes). 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.

See scripts/ci/README.md for the CI plumbing and test-infrastructure/README.md for the venue map.
