fix(cli): validate --rule ID and match case-insensitively - #1540
validating the --rule <id> argument against recognized override hygiene rules (OA001–OA011, PD001–PD002) and matching case-insensitively.
Previously, --rule accepted any arbitrary string via requireFlagValue without validating against recognized rule IDs. In src/cli/overrides.ts, findings were filtered via exact equality (f.ruleId === options.rule), which meant:
Providing a lowercase rule ID (e.g. --rule oa001) failed exact equality, silently filtering out all findings and printing ✔ No override hygiene issues found. with exit code 0.
Providing an unrecognised rule ID (e.g. --rule OA999 or --rule foo) was accepted silently and exited 0, creating a silent false negative in CI pipelines with --fail-on.
Now, --rule validates against OVERRIDE_RULE_IDS and normalizes the input to uppercase. Unknown rule IDs are rejected with:
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Rule IDs provided to the overrides command are checked against the supported IDs. Unsupported values produce an error listing accepted IDs.
Rule IDs are normalized to uppercase, regardless of letter case, in both --rule <id> and --rule=<id> formats.
Empty rule IDs and values beginning with a hyphen are rejected in both formats.
The overrides command now accepts supported rule IDs regardless of case and normalizes them to uppercase. It rejects unknown IDs in both --rule <id> and --rule=<id> forms.
Changes: Override Rule Validation
Layer / File(s)
Summary
Rule ID allowlist and parser src/overrides/types.ts, src/overrides/index.ts, src/cli/args.ts
The overrides module exports the supported OA and PD rule IDs. The CLI parser rejects unknown IDs and returns recognized IDs in uppercase.
Argument parsing and tests src/cli/args.ts, tests/cli/overrides-args.test.ts
Both --rule forms use the parser. Tests cover case-insensitive normalization and errors for unknown IDs.
OWASP/cve-lite-cli#1466: Routes the same --rule option through a required-value helper before normalizing and validating it.
Merge Risk: Low · up to 87964
The rule validation change is mergeable with minor testing follow-ups: independently verify the valid-rule message and cover lowercase filtering through the command’s exit status.

The title accurately describes the CLI fix and uses a valid lowercase description, but it uses the scoped prefix "fix(cli):" instead of the required "type:" form.
Rename the title to use an allowed type followed directly by a colon, for example: "fix: validate --rule ID and match case-insensitively".

Full details: Linked Issues check
Explanation
[#1536] The CLI now normalizes --rule values with toUpperCase() and validates them against OVERRIDE_RULE_IDS. The parser handles both --rule <id> and --rule=<id>. The list contains OA001 through OA011 and PD001 through PD002. Unknown values raise an error that includes the supplied value and the valid rule list. The existing exact filter therefore receives canonical uppercase IDs. Tests cover lowercase values, both argument forms, and unknown IDs.

Explanation
The supplied change summary lists four changed files. src/cli/args.ts adds parsing and validation. src/overrides/types.ts defines the canonical rule list. tests/cli/overrides-args.test.ts verifies the behavior. src/overrides/index.ts re-exports the rule list. These changes support #1536. No unrelated change is established.

Explanation
Users can select supported rules without regard to case, and unknown IDs produce an error. Issue #1536 asks for both behaviors and a list of valid IDs. I confirmed that the change normalizes both --rule forms, lists all 13 requested IDs, and rejects unknown IDs before the audit runs.

Keep new rules selectable with --rule.
If a new rule is registered without updating this list, users cannot select its findings. I’d derive the IDs from ALL_DETECTORS and add a test that passes every registered ID through the parser.

Thanks @coder-Yash886, this does exactly what #1536 asked. On examples/all-scenarios with --fail-on high, --rule oa001 and --rule=pd001 used to print "No override hygiene issues found" and exit 0, and now they report the findings and fail like the upper-case form does. --rule OA999 stops with the message from the issue word for word. The tests also catch each part of the change when I take it out.
Two small things before I merge, both about keeping this in sync with the rest of the code.

Check the supported rule list independently.
Users can receive a changed valid-rules list without this assertion failing because it uses the parser’s tuple. The build catches an isolated OA010 omission. I suggest an explicit list to check the CLI message independently.

Test the executable’s unknown-rule exit status.
If an invalid rule exits successfully, automation can miss findings. The new tests call only parseArgs. I suggest running overrides <fixture> --rule OA999 --fail-on low against a project with an OA001 finding, then asserting exit code 1 and the unknown-rule error.

Thanks, that was quick. The list is in one place now and the error texts are unchanged. You're right that deriving the type trips the test typecheck gate, so the satisfies check makes sense.
One gap left: it catches a list entry that isn't a rule, but not a rule missing from the list. Adding OA012 to the type and a detector, but not the list, still compiles, so --rule OA012 would be rejected. CodeRabbit's two-line check closes that direction:

Test the exit status with a lowercase rule.
If lowercase rule filtering regresses, users can get exit 0 despite a qualifying finding. I’d add a command-level test with an OA001 finding, --rule oa001, and --fail-on high, and assert exit 1. The parser tests cannot catch that regression.

Thanks @coder-Yash886, that closes it. Adding a rule to the type without adding it to the list now fails the build, and so does dropping one from the list, so the two can't drift in either direction. The test pulls the list straight from src/overrides/types.ts and the extra export in args.ts is gone.
I ran it again on examples/all-scenarios with --fail-on high: --rule oa001 and --rule pd001 report their findings and exit 1, and --rule OA999 and --rule foo stop with the message from the issue. Approved, I merge these one at a time so it will land shortly.
