CPP_EXTENSIONS = [".cpp", ".cc", ".cxx", ".h", ".hpp"]
EVIDENCE_RE = Regex.union("drogon", "registerHandler", "PATH_LIST_BEGIN", "PATH_ADD", "METHOD_LIST_BEGIN", "METHOD_ADD", "ADD_METHOD_TO", "ADD_METHOD_VIA_REGEX")

Precompiled union for the per-file evidence gate in analyze, so it costs a single PCRE2 match instead of up to eight naive substring scans.

HTTP_METHODS = {"Get" => "GET", "Post" => "POST", "Put" => "PUT", "Delete" => "DELETE", "Patch" => "PATCH", "Head" => "HEAD", "Options" => "OPTIONS"}
JSON_ACCESS_RE = Regex.union("->getJsonObject(", "->getJsonValue(")

extract_params's per-line JSON-body-access check is used twice (once positively, once negated) on the same line buffer; precompile it once instead of repeating the two-way includes? OR each time.

MACRO_CALL_PATTERNS = {"METHOD_ADD" => /\bMETHOD_ADD\s*\(/, "ADD_METHOD_TO" => /\bADD_METHOD_TO\s*\(/, "ADD_METHOD_VIA_REGEX" => /\bADD_METHOD_VIA_REGEX\s*\(/, "PATH_ADD" => /\bPATH_ADD\s*\(/, "WS_PATH_ADD" => /\bWS_PATH_ADD\s*\(/, "WS_ADD_PATH_VIA_REGEX" => /\bWS_ADD_PATH_VIA_REGEX\s*\(/}

Crystal recompiles an interpolated regex literal on every evaluation (a full PCRE2 JIT compile). The macro set is fixed, so precompile its matchers once; the method/class matchers interpolate discovered names and are memoized per name instead.

METHOD_BLOCK = /\{\s*((?:drogon::)?(?:Get|Post|Put|Delete|Patch|Head|Options)\b[^{}]*)\}/

{Get, Post} method list: brace block whose first token is a verb.

REGEX_REGISTER_HANDLER = /app\(\)\s*\.?\s*registerHandler(?:ViaRegex)?\s*\(\s*"([^"]+)"/

Instance-side view of the same declaration. The per-file rescues live on this base class, which has no way to name the analyzer that is running inside them, so a skipped file could not be attributed to a tech. Deriving it from analyzer_for keeps the name written exactly once.
