// src/v2/compiler/self_host/fixed_point_test.dag
// Scope: the ONLY live-executed self-host coverage. Discovered + run by the live CI gate
// (.github/workflows/ci.yml: ci_claim_gate --source-root src/v2 --scan-dir src/v2/test), which
// executes `test fn () -> Bool` decls in *_test.dag files (GREEN pass = true, PERTURB pass = flips).
// (.github/workflows/ci.yml:59: ci_claim_gate --source-root src/v2 --scan-dir src/v2/test).
// IMPORTANT: `test fn` discovery scans the WHOLE --source-root (src/v2) recursively — NOT just
// --scan-dir (that flag governs only the separate `unified_claim_*` data scan). So this file is
// discovered at its compiler/self_host/ path, not because it lives under src/v2/test. The gate
// runs each `test fn () -> Bool` (GREEN pass = true; PERTURB pass = body must flip to false).
// Status:
// - fixed-point predicate (self_host_fixed_point_digests_match) de-risked on FIXTURE stages;
// - Stage-A structural pre-check (stage_emission_equality) executed here;
