The first commit of this branch is the Smart CI change as of the rebase
onto 9f85f104. A review of it found places where the engine could run
fewer tests than a change needs; each now runs everything or selects the
right tests, with a test that fails when its fix is reverted.
Engine:
- A `#define NAME "literal"` line counted as naming a role but selected
nobody, so the tests that start the blocking-git probe through their
marker macros would not have run. The scan now follows NAME, as a whole
word, to the code that uses it, through chains of up to 4 macros; a
define it cannot follow runs everything.
- main dispatches through the role table, so no edge leads from main to a
handler. A table entry the engine cannot read, or whose handler is not
exactly one function, was skipped; it now runs everything.
- In a runner file, only a test case names a role's literal. The runner's
own helper that reads the marker no longer counts as a spawner, so a
role only the runner names runs everything again.
- A handler reached first by a parse gap or by the spawn lift was never
lifted. Role lifts and parse gaps now run to a fixpoint, before the
runner check and again after the spawn lift.
- A reached sink that main calls (the blocking-git probe) counted as a way
into main and hid the real one: #2644 now names the start-up path main
-> cbm_index_supervisor_capture_build_fingerprint.
- No pointer past the end of a role line; the RUNNER_REACHED note clamps
its prefix.
CI:
- pkg/npm/README.md, which test_cli reads, runs the test legs instead of
the docs tier.
- The build rule lists the harness scripts the test legs run:
run-test-wave.py, path-safety.sh, clean.sh.
- The revert guard rejects the ancestor's coverage when a diff fails.
- The vetoed selection is uploaded (test-selection-vetoed).
Docs: SMART_CI.md states the new fail-safe cases, the version that lacks
the new config keys, the selection base, and that the narrowed leg builds
with gcc while the coverage comes from clang.

pr.yml and test-impact-artifact.yml run scripts/ci/test-impact-select.sh,
-bundle.sh and -publish.sh as commands, but they were committed 100644
(core.fileMode is false in this clone, so the disk mode never reached the
index), and the PR shadow job failed with "Permission denied" (exit 126).
tests/test_script_exec_bit_contract.sh reports exactly this; it skipped the
scripts locally while they were still untracked.

Producer. test-impact-artifact.yml publishes, on every push to main, the
commit's team artifact bundle: its frozen graph, built incrementally from the
previous bundle, and its per-test coverage map, re-run only for the suites
the push selects (scripts/ci/test-impact-publish.sh). A weekly run rebuilds
both from scratch and fails when the incremental graph's topology differs
from the full one. Bundles are Actions artifacts kept 30 days, never
committed.
Shadow. The report-only test-impact-shadow job also builds the checkout and
runs `test-impact select` against the base side of the PR merge commit
(scripts/ci/test-impact-select.sh). A bundle is used only when it comes from
a successful main-branch producer run for exactly that commit
(scripts/ci/test-impact-bundle.sh). The job stays continue-on-error and
outside ci-ok.
Narrowing switch, PR CI only. While the repository variable
TEST_IMPACT_MODE is `gate`, a select-tests job turns the engine's answer into
the tests the test-unix and test-windows legs run. Unset, nothing changes.
It fails open by construction:
- scripts/test-impact/selection.py is the only place an answer becomes a
runner filter. Only a well-formed selected lane whose filter matches its
own suite list narrows; run-all answers, a lane that selects nothing,
unknown schemas or tokens, and any crash run everything.
- `test` passes a selection only from a successful, narrowed select-tests
run; ci-ok does not need select-tests. A broken selection costs minutes,
never coverage.
- scripts/run-tests-parallel.sh launches only the selected suites and keeps
every guard on the selected list. A selected suite the build does not
register fails the run, unless the engine saw its registration as
conditional; then it is dropped with a notice, exactly as a full run of
that build never runs it. Each runner judges its own tokens, so a selected
test that does not exist fails its suite.
- The shard manifest records the selection's digest, and
verify-shard-union.sh requires every shard of a leg to agree on it.
- Dry runs and releases never pass a selection (lane-wiring contract).
Also fixed on the way:
- publish crashed on any run-all push: a run-all lane carries
"suites": null.
- the git-facts hostile-diff probe re-ran the runner with the parent's
CBM_TEST_ONLY_FILE still set; under a narrowed run naming its suite it
re-ran the spawning test, which spawned again. The child now clears it
(a new test fails without that).
- the select summary crashed on the same null suites.
Contracts: tests/test_test_impact_selection.sh (Step 0z8),
tests/test_harness_selection.sh (Step 2c, the real runner through the real
harness), and new cases in the lane-gate and lane-wiring contracts.
