Thank you for this contribution. The changes improve the codebase quality nicely.

The allowlist approach is the right fix for Issue #4904. Two issues to resolve before merging:

1. Query parameter values are not validated — only keys are

The key validation loop correctly restricts keys to [a-zA-Z0-9-_.]:

for raw_key, raw_value in request.args.lists():
    if not raw_key or not all(ch.isalnum() or ch in "-_." for ch in raw_key):
        return jsonify({"error": "Proxy path not allowed"}), 403
    safe_query.append((raw_key, raw_value))  # raw_value passes through unvalidated

raw_value is the list of strings for that key (from .lists()), and none of its elements are inspected. An attacker can send arbitrary content in parameter values — including CRLF sequences (%0d%0a), null bytes (%00), and other control characters. While the requests library prevents HTTP header injection at the transport level, the upstream node's query-handling code may not. The fix is to apply a similar character allowlist to each value string, e.g. all(ch.isalnum() or ch in "-_.,:" for ch in v), or at minimum reject any value that contains ASCII control characters (any(ord(ch) < 32 for ch in v)).

2. scripts/baselines/fetchall_existing.txt adds two duplicate lines

The diff adds:

+node/rustchain_v2_integrated_v2.2.1_rip200.py:).fetchall()
+node/rustchain_v2_integrated_v2.2.1_rip200.py:).fetchall()

Both lines are exact duplicates of entries already present in the file at this path. If fetchall_existing.txt is used as a regression baseline (e.g., to detect new raw SQL patterns), the duplicates are noise that will cause future diff-based checks to produce false "already known" matches and mask real additions. If the duplicate lines are intentional (the script itself has duplicate occurrences that must be accounted for), a comment explaining why would clarify intent. Otherwise, remove the two duplicate entries.
