…y vacuous
Four independent defects each made the Hypatia gate unconditionally vacuous:
1. `scan . > hypatia-findings.json 2>&1` folded the stderr summary into the JSON
payload, so `jq empty` failed and the guard wrote `[]`. Every count read 0 and
`Fail on critical findings` could not fire on any input.
2. The availability probe tested `[ -d "$HOME/hypatia/scanner" ]`, which is
unsatisfiable -- hypatia has no `scanner/` directory. The scan was skipped and
a stub `[]` was written: a second, independent route to permanent green.
3. The clone used `${REPO_OWNER}`, which 404s outside `hyperpolymath`. A failed
clone was indistinguishable from "unavailable".
4. Annotations emitted `\(.message)`, a key findings do not have, so every one
read `[hypatia] null` -- on an absolute runner path GitHub cannot anchor.
Threshold is unchanged: critical-only.

Both paths set the scanner readiness output to
false. The later stub steps write[], and the critical-findings checks are skipped. A required security gate can then pass without either scanner running.

Fail the panic-attack step when the scan fails.
This branch only writes a warning. The later jq commands then fall back to zero counts, and PA_EXIT does not fail the job. A non-zero scan exit or malformed payload can therefore pass the critical-findings gate without a valid scan result. Exit non-zero for both conditions before writing outputs.

The Hypatia gate in this repo has never been able to fail
Static Analysis Gateis green here, and that green means nothing. Four defect classes, eachindependently sufficient to make the gate vacuous. Measured in this repo: defects 1 and 4 are present and fixed here. Defects 2 and 3 were not present in this file — that code is already correct here, and is described below only to document the class.
1.
2>&1folded the scan summary into the JSON payloadPer Hypatia's own contract (
hyperpolymath/hypatia,lib/hypatia/cli.ex:82-87) findings go tostdout and a one-line summary always goes to stderr. Folding them together makes the file
invalid JSON, so
jq emptyfails, the guard concludes "the scan did not run", and[]is written.Every count then reads 0 and
Fail on critical findingscannot fire on any input.Fixed: stderr stays on the log;
--exit-zerois passed so exit1("findings exist") is no longermistaken for a crash; the payload is validated with
jq -e 'type == "array"'.2. The availability probe tested for a directory that does not exist
hyperpolymath/hypatiahas noscanner/directory, so this is unsatisfiable. The scan step wasskipped and a
Create stub findingsstep wrote[]— a second, independent route to permanentgreen, invisible at the check level because the check still reported success.
Fixed: probe
$HOME/hypatia/mix.exs, which is what a successful clone actually leaves behind. The"unavailable" notice is promoted from
::noticeto::errorso a missing scanner is visible.3. The clone used
${REPO_OWNER}, which 404s outsidehyperpolymathmetadatastician/hypatiadoes not exist. In those repos the clone silently failed(
2>/dev/null || true), which is indistinguishable from "unavailable" — see defect 2.Fixed: clone

What this changes in practice
The gate can now fail. Threshold is unchanged and remains critical-only
(
steps.scan.outputs.critical > 0); high/medium/low continue to annotate without blocking.If this PR turns the gate red, that is the fix working — the finding was always there and the gate
could not report it. Do not merge a red one by overriding the gate. Either the finding is real
and wants fixing, or it is a false positive that wants filing upstream.
Provenance
Same four-defect repair, applied identically across every repo carrying this workflow. The transform
is a byte-exact block substitution with post-conditions asserting the defect is gone and the cure is
present; it refuses to write a file that fails any of them. Each post-condition is scoped to a live
shell construct, never to a comment, so the explanatory comments above cannot satisfy their own
assertions.
