Add the leading-BOM check to both workflow copies.

The Unicode regex alone does not satisfy the required byte-wise check for a UTF-8 BOM at byte offset zero.

In @.github/workflows/dogfood-gate.yml at line 122, Update the PATTERNS check in
both .github/workflows/dogfood-gate.yml (lines 122-122) and
satellites/a2mliser/.github/workflows/dogfood-gate.yml (lines 122-122) to
include a byte-wise check for the UTF-8 BOM sequence EF BB BF specifically at
byte offset zero, while preserving the existing Unicode patterns and merging the
new check into the same validation.

🔴 HIGH RISK

The grep command is searching for an empty string, which matches every line in every file and ignores the defined $PATTERNS variable. It should be updated to use the variable; the recursive -r flag is redundant when used with find -exec on individual files.

-exec grep -aPl "$PATTERNS" {} \; > /tmp/empty-lint-results.txt 2>/dev/null

Use the invisible-character pattern in both workflow copies.

The empty pattern matches every non-empty eligible file, so clean files produce false findings.

In @.github/workflows/dogfood-gate.yml at line 133, Update the grep invocation
at .github/workflows/dogfood-gate.yml:133-133 to pass "$PATTERNS" so only
invisible-character matches are reported; apply the same change at
satellites/a2mliser/.github/workflows/dogfood-gate.yml:133-133.

🔴 HIGH RISK

The grep command is searching for an empty string instead of the intended patterns. This will cause the gate to flag every source file as a violation.

Suggested change
-exec grep -aPrl "" {} \; > /tmp/empty-lint-results.txt 2>/dev/null
-exec grep -aPl "$PATTERNS" {} \; > /tmp/empty-lint-results.txt 2>/dev/null
