 * Which context canon a run emits.

 *    `setup.md` (from `aih contract`) behind a thin RULE_ROUTER. The lean,
 *    evidence-first surface that reads as one contract, not a doc family.
 *  - `legacy` — the full pre-contract doc family (INDEX/architecture/conventions/
 *    tasks/SETUP-TASKS/VALIDATION/project-guardrails/example-skill +
 *    REGENERATION/harness-update/other-tools). Byte-identical to the old output, for
 *    a team mid-migration; the compiler NEVER deletes, so this is the non-destructive
 *    escape hatch, opt-in only.
