Check if a file path looks like a test file. */

Extract a JSON string property from properties_json. * Writes into buf, returns buf on success, NULL on miss. */

Extract a JSON string value by key (simple strstr-based, no full parse). */

Extract string literal from first named child (for nodes wrapping string content). */

Look up a module-level string constant by name. */

Try to find a registered type for a "namespaced" QN. * * Lookup order: * 1. exact QN match * 2. module_qn + "." + qn (same-file class) * 3.

Consume an identifier (ASCII rust ident). Returns end position or * `from` if no identifier. */

True when mimalloc made this block, so it must be returned to mimalloc. * NULL is nobody's: callers handle it before asking. */

Navigate to a node by dot-separated path. */

Ensure leaves array has capacity for one more entry. Returns false on allocation failure.

Flush current leaf page to file

Append a base name (generic args stripped) to out[] if non-empty.

Extract the last path segment from a QN. Returns pointer into s. * Recognizes both '.' (most langs) and Rust/C++ '::' separators, so a * scoped call

Emit a type assignment if var_name and constructor type are valid.
