46ef0204ef Remove secretQuestion from FP exclusion list
secretQuestion is ambiguous: it could be the question text (not
sensitive) or a security question answer. Worse, the regex
secrets?(question) also matches secretQuestionAnswer, which is
clearly sensitive. Drop it to avoid false negatives.

345b842edc Java: add RegexpCheckBarrier to trust-boundary-violation sanitizers
The trust-boundary-violation query only recognized OWASP ESAPI validators
as sanitizers. ESAPI is rarely used in modern Java projects, while regex
validation via String.matches() and @javax.validation.constraints.Pattern
is the standard approach in Spring/Jakarta applications.

RegexpCheckBarrier already exists in Sanitizers.qll and is used by other
queries (e.g., RequestForgery). This wires it into TrustBoundaryConfig,
so patterns like input.matches("[a-zA-Z0-9]+") and @Pattern annotations
are recognized as sanitizers, consistent with the existing ESAPI treatment.

f338ded349 Java: treat hash/encrypt/digest methods as sensitive-log sanitizers
The sensitive-log query (CWE-532) lacked sanitizers for hashed or
encrypted data, while the sibling cleartext-storage query (CWE-312)
already recognized methods with "encrypt", "hash", or "digest" in their
names as sanitizers (CleartextStorageQuery.qll:86).

This adds an EncryptionBarrier to SensitiveLoggingQuery that applies the
same name-based heuristic, making the two queries consistent. Calls like
DigestUtils.sha256Hex(password) or hashPassword(secret) are no longer
flagged when their results are logged.

20cfe29199 Java: reduce false positives in sensitive-log by expanding FP exclusion regex
The getCommonSensitiveInfoFPRegex() only excluded "null", "tokenizer", and
"tokenImage", causing widespread false positives for common non-sensitive
variable names containing "token" or "secret".

This adds exclusions for three categories:
- Pagination/iteration tokens: nextToken (AWS SDK), pageToken (GCP),
  continuationToken (Azure), etc.
- Token metadata: tokenType (OAuth), tokenEndpoint (OIDC), tokenCount,
  tokenIndex, tokenLength, tokenUrl, etc.
- Secret metadata: secretName (K8s/AWS), secretId (Azure),
  secretVersion, secretArn, secretPath, etc.

All truly sensitive variable names (accessToken, clientSecret, secretKey,
refreshToken, etc.) remain correctly flagged.

9ff4ed286f Java: recognize Path.toRealPath() as path normalization sanitizer
PathNormalizeSanitizer recognized Path.normalize() and
File.getCanonicalPath()/getCanonicalFile(), but not Path.toRealPath().

toRealPath() is strictly stronger than normalize() (resolves symlinks
and verifies file existence in addition to normalizing ".." components),
and is functionally equivalent to File.getCanonicalPath() for the NIO.2
API. CERT FIO16-J and OWASP both recommend it for path traversal defense.

This adds toRealPath to PathNormalizeSanitizer alongside normalize,
reducing false positives for code using idiomatic NIO.2 path handling.

0c5e89a68e Exclude bounds-check arithmetic from tainted-arithmetic sinks
The java/tainted-arithmetic query now recognizes when an arithmetic
expression appears directly as an operand of a comparison (e.g.,
`if (off + len > array.length)`). Such expressions are bounds checks,
not vulnerable computations, and are excluded via the existing
overflowIrrelevant predicate.

Add test cases for bounds-checking patterns that should not be flagged.

da4a2238bc Address PR review: add Signature.getInstance sink, HMAC/PBKDF2 whitelist, fix test APIs
- Model Signature.getInstance() as CryptoAlgoSpec sink (previously only
  Signature constructor was modeled)
- Add HMAC-based algorithms (HMACSHA1/256/384/512, HmacSHA1/256/384/512)
  and PBKDF2 to the secure algorithm whitelist
- Fix XDH/X25519/X448 tests to use KeyAgreement.getInstance() instead of
  KeyPairGenerator.getInstance() to match their key agreement semantics
- Add test cases for SHA384withECDSA, HMACSHA*, and PBKDF2WithHmacSHA1
  from user-reported false positives
- Update change note to document all additions
