🏁 Script executed:

#!/bin/bash
set -euo pipefail
rg -n -C 3 'EXAV_YR_BIN|yara-x-cli|\byr\b' .github/workflows/ci.yml Makefile

Repository: sylvinus/exav

Length of output: 1145


Configure the YARA oracle for this job. make test-yara-diff skips and exits successfully when EXAV_YR_BIN is unset. The workflow does not configure EXAV_YR_BIN or install yara-x-cli, so the job can pass without running the differential tests. Install yara-x-cli, set EXAV_YR_BIN to yr, or make the missing oracle fail the job.

In @.github/workflows/ci.yml at line 53, Update the CI job containing the
checkout step to ensure make test-yara-diff runs with a configured YARA oracle:
install yara-x-cli and set EXAV_YR_BIN to yr, or explicitly fail the job when
the oracle is unavailable. Do not leave the test able to skip successfully due
to an unset EXAV_YR_BIN.

Disable persisted checkout credentials in both jobs.

actions/checkout@v7 persists the job token by default. In lint, make test-helm runs scripts/test-helm.sh from the checked-out repository, so repository-controlled code can read the persisted contents: read token.

The publish job's packages: write token is not used by repository-controlled commands. Its later steps validate Cargo.toml, authenticate Helm, and package and push the chart. None needs Git authentication.
