/**
 * Override loading (D-006): code defaults plus a validated override file;
 * the override wins, and a malformed file - structurally OR semantically -
 * throws with the file path and offending harness in the message. A silent
 * fallback to defaults, or a garbage value flowing onward, would ship an
 * override bug invisibly. Pure over TEXT: the caller reads the file and
 * passes its content; nothing here touches the filesystem.
 *
 * Merge semantics: recursive to full depth for plain-object sections (a
 * partial nested override keeps its sibling keys); arrays replace
 * wholesale; every leaf is type-checked against the code default's shape,
 * closed string vocabularies are enforced, and any path whose default
 * carries a RegExp cannot be overridden from JSON.
