…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.

Do not convert empty scanner output into a clean scan.
Line 57 converts a scanner crash or empty output into []. The array check then succeeds, all counts become zero, and the critical gate passes. Keep stub findings only for the explicit unavailable-scanner path. Fail this step when an installed scanner produces an empty or non-array payload.

GitHub Actions workflow commands escaping command properties message percent carriage return newline colon comma official documentation
💡 Result:
To ensure GitHub Actions correctly processes workflow commands (which follow the format::name key=value,key=value::message), you must escape specific characters if they appear within your command properties or message content [1][2]. Because these characters carry functional meaning for the runner’s parser, failing to escape them can cause the command to be truncated, misparsed, or terminated prematurely [1][3]. The official escaping requirements are implemented by the GitHub Actions toolkit as follows [1][2]: Escape Sequences: - Percent (%): %25 [1][2] - Carriage Return (\r): %0D [1][2] - Newline (\n): %0A [1][2] - Colon (:): %3A [1][2] (Required for properties only) - Comma (,): %2C [1][2] (Required for properties only) Application Rules: 1. Command Properties (key=value): Properties require the most rigorous escaping [3]. You must escape all five characters listed above (%, \r, \n,:, and,) to prevent the runner from misinterpreting property delimiters or separators [1][2][3]. 2. Message Body: The message (the text following the final::) is the last part of the command and is handled more leniently [3]. Only the percent (%), carriage return (\r), and newline (\n) characters must be escaped [1][2][3]. Colons and commas do not need to be escaped in the message body, as they will not break the command structure [1][3]. Note: Workflow command and parameter names are case-insensitive [4][5]. If you are working in a complex environment where manual escaping is error-prone, it is recommended to use official libraries like @actions/core, which handle these transformations automatically [1][6].

Escape scanner values before writing workflow commands.
Both jq pipelines interpolate .file into the file property and .reason // .message // .type into command data. Escape %, carriage returns, and newlines in messages. Escape :, ,, %, carriage returns, and newlines in properties at both annotation sites.

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
hyperpolymath/hypatiaexplicitly.4. Every annotation said
null, on a path GitHub cannot anchorThe jq emitted
\(.message), but findings have nomessagekey — the real keys areaction, file, line, reason, rule_module, severity, type. And.fileis an absolute runner path.Positive control on a real finding from the
hybrid-automation-routerartifact:::error file=/home/runner/work/hybrid-automation-router/hybrid-automation-router/.envrc,line=23::[hypatia] null::error file=.envrc,line=23::[hypatia] Secret found: Generic API keyFixed:
.reason // .message // .type // "finding", and.filemade workspace-relative withltrimstr($ws + "/"). The fallback chain means this is correct whether or not amessagekey isever added.
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.
