Fixed two failing integration tests and cleaned up Artery.ts:

**Bug Fixes:**
1. Fixed transformation/filter order in Artery.processMessage()
   - Transformations now apply BEFORE filters (was reversed)
   - Filters now correctly evaluate transformed values

2. Added batchTimeout to Integration test
   - Vein flushes partial batches after timeout

**Code Quality (Artery.ts):**
- Removed `async` from methods without `await`
- Fixed floating promises with `void` operator
- Refactored processLoop to eliminate linter warnings
- Updated tests for synchronous error handling
- Zero linting errors in modified files

**Test Results:**
✅ 130/130 circulatory tests passing
✅ 764/764 total tests passing
✅ Coverage: 87.62% (core), 96.92% (patterns)

Closes #19
This commit completes issue #19 (Phase 4: Circulatory System) with:

**Bug Fixes:**

To fix this issue, remove the second argument ({ pressed: false, clickCount: 0 }) from the super call inside the ButtonComponent constructor on line 24. Only the necessary arguments that are used by the superclass (VisualNeuron) should be passed. In general, verify the signature of the superclass constructor to ensure the arguments match, and remove any extra arguments that are not used by the parent. Specifically, change:

super(props, {
  pressed: false,
  clickCount: 0,
});

to:

super(props);

No additional imports or changes are required for this fix.

To fix the issue, remove the superfluous trailing argument in the call to the TestSubject constructor. In examples/theater-demo/button.laboratory.ts, line 32 currently calls new TestSubject(ButtonComponent, {...}). The correct fix is to pass only the expected number of arguments, i.e., just the ButtonComponent, unless the TestSubject constructor is meant to accept configuration. Since CodeQL says only one argument is accepted, change line 32 to new TestSubject(ButtonComponent). No imports or method definitions are needed—just the code edit within this file.

To fix the problem, remove the unnecessary second argument passed to the TestSubject constructor on line 67 in examples/theater-demo/button.laboratory.ts ({ label: 'Click Me' }, autoMount: true). Instead, only provide the minimum required arguments—likely just the ButtonComponent class. Review other similar instances in the file to ensure they are also passing only required arguments, but since only line 67 is flagged, focus on correcting that line by removing the options object.

To fix this issue, remove the unnecessary argument passed to the TestSubject constructor on line 112. That is, only pass ButtonComponent to the constructor, and delete the options object containing initialProps and autoMount. Confirm that this call matches the intended constructor signature used throughout the file. Only edit the call on line 112 in examples/theater-demo/button.laboratory.ts, ensuring the rest of the file is left unchanged.

Copilot Autofix

AI 7 months ago

To fix this issue, we should ensure that only the necessary arguments are passed to the TestSubject constructor. Typically, if TestSubject is a test utility that mounts a component, it likely expects either the component class and config bundled in an options object, or just the component definition and grabs further data later. Based on the current code and the pattern in the rest of the file, it seems the correct approach is to pass a single options object with both the component and the initial configuration included as properties—specifically, of the form { component: ButtonComponent, ... }. Therefore, in the file examples/theater-demo/button.laboratory.ts, at line 154–157, we should replace new TestSubject(ButtonComponent, { ... }) with new TestSubject({ component: ButtonComponent, ... }). This change preserves the intended configuration and aligns with the probable constructor implementation for TestSubject.

No new methods or imports are necessary; only the parameter-passing at line 154–157 needs to be corrected.

Superfluous trailing arguments Warning

Superfluous argument passed to

Copilot Autofix

AI 7 months ago

The fix is to remove the unnecessary second argument passed to the TestSubject constructor at line 197 in examples/theater-demo/button.laboratory.ts. Specifically, change:

new TestSubject(ButtonComponent, {
  initialProps: { label: 'Initial' },
  autoMount: true,
}),

to just:

new TestSubject(ButtonComponent),

This corrects the invocation so that no useless trailing arguments are passed, matching the constructor's definition and intent. No other changes or imports are needed.

To fix this problem, simply remove the unused variable declaration for component in the callback to propsUpdateExperiment.setTest. Specifically, delete (or comment out) line 204, which appears as: const component = subject.getComponent() as ButtonComponent;. No further changes are needed, as everything else in the function works via the subject variable. No additional imports, definitions, or method changes are necessary.

Copilot Autofix

AI 7 months ago

The best way to fix this problem is to use a dedicated password hashing library that implements secure password-based key derivation functions, such as bcrypt, scrypt, or Argon2. The most commonly used in Node.js is bcrypt. Instead of implementing custom iterations and SHA-256 salting, you should use bcrypt's built-in functionality, which efficiently combines salting, slow hashing, and adaptive work factors.

Steps to fix:

  • In src/immune/authentication/TCell.ts, replace the contents of hashPassword so it uses bcrypt to hash passwords, using its own built-in salting/work factor.
  • Import bcrypt at the top.
  • Modify hashPassword accordingly: generate a salt with bcrypt if needed, or accept a salt as an argument (note: bcrypt expects the full salt string, not just random bytes).
  • If password hashes are stored as outputs from hashPassword, you don't need to store the salt separately; bcrypt embeds salt data in the hash string itself.
  • Changing the function signature: if salt is still passed, use it as a salt string for bcrypt (eg. for legacy support); otherwise, you can remove salt as a parameter and generate it as needed on user registration/update, and use only the hash for comparison on login.

However, to preserve current function signatures and minimize wider changes outside the provided code, refactor hashPassword to use bcrypt.hash and accept salt as the work factor/salt string. You can generate a salt with bcrypt.genSalt(workFactor) during registration, and store the hash output.

Required edits in src/immune/authentication/TCell.ts:

  • Add import * as bcrypt from 'bcrypt';
  • Change the definition of hashPassword so it uses bcrypt.hash or bcrypt.hashSync (preferably the async API).

Bad HTML filtering regexp High

This regular expression does not match script end tags like </script >.

Copilot Autofix

AI 7 months ago

The best fix is to use a more robust and permissive regular expression for matching HTML script tags in attacks, one that accounts for superfluous whitespace, attributes, and browser-end-tag error handling—all of which can occur in malicious input.

The recommended change is to replace the regex on line 283:
From:

/<script[^>]*>.*?<\/script>/gi

To something like:

/<script\b[^>]*>([\s\S]*?)<\/script\b[^>]*>/gi
  • This matches </script foo="bar">, </script >, and other similar cases, and allows for any attributes or spaces before the closing >.
  • It preserves case-insensitivity.
  • To be extra robust, we should use [\s\S]*? instead of .*? to match newlines as well.
  • For maximum security and detection, consider using an established library like xregexp or even an HTML parser, but if only the regex can be changed, the above provides significantly broader coverage.

Implementation:

  • In the file src/immune/detection/Antibody.ts, at line 283, update the regex for the script tag pattern as described.

To remedy this, the check for malicious URL schemes should be expanded to also remove or neutralize URLs starting with data: and vbscript: in addition to javascript:. To avoid altering intended functionality, the safest approach is to modify the relevant regex and logic to account for these protocols.

  • In src/immune/sanitization/Macrophage.ts, expand the regex and protocol replacement to match any of javascript:, data:, or vbscript:, case-insensitive.
  • Optionally, for clear tracking, update the removed array with a generic message such as "<protocol> protocol" for every protocol removed.
  • No additional dependencies or method definitions are necessary.

To fix this issue, the best approach is to repeatedly apply the HTML tag-stripping regex until no further matches are found. This guarantees that any tags missed in the first pass (due to string manipulation side-effects or crafted input) are fully removed, effectively preventing injection vulnerabilities from malformed or nested tags. Edit line 279 in file src/immune/sanitization/Macrophage.ts to use a loop or do-while structure that repeatedly applies the regex until the string stabilizes. This change preserves existing functionality while improving the safety of the sanitization. No new imports or definitions are needed.

Copilot Autofix

AI 7 months ago

To properly sanitize the string and ensure that all HTML event handler attributes are fully removed, the replacement must be applied repeatedly until no matches remain. This can be accomplished by looping: compare the string before and after each replacement, and continue looping while the string changes. This logic should be applied solely to the event handlers removal region (lines 263-268) so as not to alter other logic or break function. No external libraries are needed, and all code remains within src/immune/sanitization/Macrophage.ts.

Replace:

264:     const eventMatches = value.match(eventPattern);
265:     if (eventMatches !== null) {
266:       removed.push(...eventMatches);
267:       value = value.replace(eventPattern, '');
268:     }

with logic that repeatedly removes all matches, adding each removed value to the removed array.

To resolve this issue without changing overall functionality, the approach should be to repeatedly apply the <script> tag removal substitution until no further matches are possible, ensuring that scripts broken up by the initial substitution are fully removed. The least invasive fix is to wrap the existing regexp-based replacement inside a do...while loop, continuing to replace until no more matches can be found (i.e., the value doesn't change).
Detailed steps:

  • Only change the code inside sanitizeHTML—specifically, lines 255–260.
  • Instead of calling .replace() once, use a do...while loop to repeatedly match and remove scripts, while accumulating all found scripts into the removed array.
  • Avoid external libraries for script removal since only built-in features can be used (unless shown otherwise).
  • Existing variables and structure are preserved, functionality unchanged except fix is now complete.
  • No new imports are required.

Bad HTML filtering regexp High

This regular expression does not match script end tags like </script >.

Copilot Autofix

AI 7 months ago

The best way to fix this error is to replace the hand-written regular expression code with a usage of a well-established HTML sanitization library—such as sanitize-html or dompurify (using JSDOM backend in Node.js). This approach addresses all the documented and subtle variants of HTML parsing, prevents bypass through browser parsing quirks, and eliminates the need for tricky regexes. Concretely, in sanitizeHTML(), replace the code that performs regex-based removal of <script> tags with a call to sanitize-html, passing in the allowedTags from the existing config as allowedTags and configuring it to remove disallowed tags (including script, style, etc.).
You will need to add the import for sanitize-html at the top of the file and update the body of sanitizeHTML to use this library instead of the regex/scriptPattern/eventPattern/etc. blocks. The function logic will preserve stats and details about removals and modifications per the original intent.
