Pull request overview
Adds three new MISRA C++ 2023 “Banned*” rule packages and their CodeQL implementations/tests, then wires them into the C++ exclusions/metadata and rules.csv mapping.
Changes:
- Add new rule packages
Banned2,Banned3,Banned4and map RULE-10-2-2/10-2-3/10-3-1 to them inrules.csv. - Add new CodeQL queries implementing the three MISRA rules and corresponding unit tests (
.qlref+.expected). - Integrate the new packages into C++ exclusions metadata (
RuleMetadata.qll+ autogeneratedBanned{2,3,4}.qll).

enumMinBits defaults the 64-bit case to signed = true (lines 142-145). This will mis-handle enums whose enumerators require an unsigned 64-bit underlying type (for example, large non-negative values > 2^63-1), potentially causing false positives/negatives in the size/signedness checks. Consider extending the range checks to distinguish signed vs unsigned 64-bit (or derive signedness directly from the enum’s value range / underlying type selection logic).

| result = 64 and signed = true | |

The PR description/checklist is still the template placeholder (no filled-in description and reviewer confirmations are unchecked). Please update the PR metadata to reflect what was changed (new rules/queries added) and confirm whether a change note is required (for new queries it’s typically not).

Change request type

Release change checklist
A change note (development_handbook.md#change-notes) is required for any pull request which modifies:
If you are only adding new rule queries, a change note is not required.
Author: Is a change note required?
🚨🚨🚨
Reviewer: Confirm that format of shared queries (not the .qll file, the
.ql file that imports it) is valid by running them within VS Code.
Reviewer: Confirm that either a change note is not required or the change note is required and has been added.
Query development review checklist
For PRs that add new queries or modify existing queries, the following checklist should be completed by both the author and reviewer:
Author
As a rule of thumb, predicates specific to the query should take no more than 1 minute, and for simple queries be under 10 seconds. If this is not the case, this should be highlighted and agreed in the code review process.
Reviewer
As a rule of thumb, predicates specific to the query should take no more than 1 minute, and for simple queries be under 10 seconds. If this is not the case, this should be highlighted and agreed in the code review process.
