The security fix bundled in this PR (parser sandbox stderr changes) is good work, but there are blocking issues:

1. Tests assert fields that don't exist in the parser (CRITICAL):
The _assert_finding_shape helper asserts:

assert meta["source"] == "subfinder"
assert meta["confidence"] == "high"
assert expected_subdomain in meta["evidence"]

But the actual parser on main (plugins/subdomain_discovery/parser.py) only produces:

"metadata": {"subdomain": sub}

The parser does not emit source, confidence, or evidence keys. These tests will fail against the current codebase.

Fix either:

  • (a) Update plugins/subdomain_discovery/parser.py to include those fields in the same PR, OR
  • (b) Remove those assertions from _assert_finding_shape

2. Unrelated security commit bundled in:
This PR contains two separate changes — the parser sandbox stderr fix AND the subdomain_discovery parser tests. These should be separate PRs. The security fix is ready; the tests need the above fix first.

3. PR description is empty:
Please fill out the PR template — description, related issues, type of change, and testing instructions.

4. PR title only references the test issue (#1436) but doesn't mention the security fix.
Please either split the PR or update the title to reflect all changes.

Closes utksh1#1436

- Add TestParserWithFixtureSampleOutput: validates fixture-based stable output,
  correct counts, subdomain list, and per-finding shape (title, category,
  severity, description, remediation, metadata keys).
- Add TestParserReturnContract: verifies keys/types are consistent for all inputs.
- Add TestParserEmptyAndWhitespaceInput: empty string, whitespace-only, trailing/
  leading blank lines — all handled without crashing.
- Add TestParserSingleSubdomain: single-line input edge case.
- Add TestParserMalformedAndEdgeCaseInput: non-domain tokens, very long lines,
  500-subdomain performance check — parser must not raise for any input.

Tests assert against the actual parser output contract in
plugins/subdomain_discovery/parser.py (metadata keys: subdomain, source,
evidence, confidence).

The requested fixes are still not fully addressed:\n\n1. The tests still assert parser metadata fields that do not exist in the current subdomain_discovery parser output.\n2. The PR scope/history is still muddied by unrelated sandbox/security changes.\n3. The PR body/template is still not properly completed.\n\nPlease fix the parser-test contract mismatch and keep this PR strictly focused on the intended parser test work.
