The workflows that fuzz the examples are dispatch-only, and GitHub will
not dispatch a workflow that is not on the default branch, so their first
real run is after merge. actionlint and the reference checker are the
only things that can fail before that.
actionlint is pinned by commit, and its tool version is pinned too so a
new release cannot change what CI enforces.
actionlint reads a local action's inputs but never checks its path
exists: uses: ./.github/actions/typo lints clean and fails only when the
job runs. Covers composite action paths, make targets including the ones
the examples matrix builds from $SANDERLING, and the scripts a run: step
invokes plus their executable bit.
Fails when it parses fewer references out of a file than that file
mentions, because a checker that matches nothing reports a safety it
never looked for.
The android health gate grepped the trace for "AddTransactionScreen",
which occurs in exactly one place: the hierarchy dump, as a resource-id.
That is a debug artifact standing in for a fact the spec already reports,
and it was wrong in both directions. Against the real 8.4MB trace with
hierarchy stripped, the old gate failed a healthy 200-step run; against a
trace carrying the marker on a transition frame without the route ever
being reported, it passed and called it healthy.
It reads extractor_changes.route now, whose values come from SCREENS in
the spec, so the gate and the app agree on what being on a screen means.
routeOf answers null on a frame showing two screens, which is exactly the
frame the marker was matching.
The drift check grows to cover both new names: extract("route") and the
SCREENS key. The fixtures are re-derived keeping the route entry and no
hierarchy at all; the full artifacts and the fixtures give byte-identical
verdicts, which is what proves the coupling is gone.
Script and fixtures move together: either alone leaves the suite red.
The comment claimed the failure was warned about; nothing warned, so a
device whose log fetch failed every step held noLogcatErrors on evidence
nobody collected.

On web every extractor reading is replaced by the one the page computed,
and the page answered logs: [], so noLogcatErrors counted an empty array
however full of errors the console was.

Four cases on real data: each leg's real verdict, plus the android trace
cut before it reached the transaction screen, which is what proves the
route gate reads a real hierarchy dump.
Also corrects the hand-written fixtures. They set is_error to false on a
plain violation; internal/trace/writer.go tags that field omitempty, so a
real trace omits it entirely. Harmless to the classifier, but a fixture
that does not look like reality is the thing that hides drift.
ios convicted on submitCommitsOneTransactionPerAction, web on both gated
properties, android ran its full 200 steps healthy. Every step is kept;
of each step only step, violations, witnesses and residuals survive.
hierarchy is replaced by the quoted "...Screen" resource ids it held, in
order. It cannot just be dropped: it is 95% of the bytes and also the
only place the android route gate's grep can match, so dropping it flips
that leg from healthy to 'never reached'. 8.4MB to 59KB.
runs/dogfood and the '### replay-ui dogfood' heading carried the same
naming error as the job name: dogfooding is why the run exists, not what
it fuzzes.
buf-setup-action was already pinned with a comment saying why; the other
five rode mutable major tags, so a tag move is an unreviewed change to
what runs. Each major currently resolves to the release named in the
comment, so this freezes today's behaviour rather than changing it.
actions/* stay on major tags: they are first-party to the runner.
folio.yml and replay-ui.yml ran the same operation: build sanderling for
a platform, bring a target up, run a spec against it, classify the trace,
upload the run. They are now one matrix over four examples, each naming
its own runner.
The job is named for what it fuzzes. 'dogfood' named why we run it, not
what runs, the same error as a diagnostic that reports a motivation
instead of an observation.
The matrix is computed by a plan job because jobs.<id>.if cannot read the
matrix context, so a static matrix has no way to leave a leg out. Seeds,
budgets, timeouts, runners and artifact names are unchanged.
Records a trace and serves it with sanderling replay. The step page URL
is a composite output rather than GITHUB_ENV, so it is scoped to the one
step that drives it.
folio-app holds the per-platform toolchain and app build, so a caller
guards one step instead of eight. folio-simulator boots the simulator,
installs folio and leaves the app stopped.
The setup-chrome / apparmor sysctl / launch-check trio is copied across
three jobs. The old comment described setup-chrome v1 semantics: under v2
stable is the default and the alternative is Chrome for Testing latest,
not a dev Chromium, so it is restated for what the pin actually does.
the reread's comment claimed the round trip was the only interval between
them; what it left out is that the two rpcs have to read the same way, which
the repo's own android backend did not do.
the runner compares the two per step, but snapshot settles and closes a
keyboard while hierarchy was a bare contentDescriptor. measured on emulator
-5556 (api 34) with an ime open: 489 nodes against the snapshot's 134. both
now come off snapshotTree under the same lock; the reread still costs ~75ms
when no keyboard is up.
the corpus reaches TxnSubmit with 999999999999999999999, AMOUNT_REGEX takes it
and AddTransactionViewModel refuses it against MAX_TRANSACTION_AMOUNT_CENTS, so
counting it was budget a double submit could hide behind.
the double taps land on home, so the counting form convicts them; what turned
0 convictions into 4 on the recorded ios run is submitCouldCommit, which drops
the windows at those three steps from 5/4/7 to 2/1/2.
