Three new reader-only tests pin the .ail.json / .ailx bijection plus AST-variant coverage. All three passed first observation across the current corpus — no roundtrip, schema-coverage, or CLI-drift gaps surfaced. - every_ailx_fixture_matches_its_json_counterpart (replaces the 3-pair handwritten exhibits): 57 paired .ailx fixtures pass. - every_ast_variant_is_observed_in_the_fixture_corpus (new): 34/34 AST variants exercised across 136 fixtures; exhaustive matches without _ wildcard so AST drift fails the build. - cli_render_then_parse_preserves_canonical_bytes_on_every_fixture (new): 136 fixtures round-trip through ail render → tempfile → ail parse with BLAKE3 identity on canonical bytes. No production code, no DESIGN.md changes (those follow in later iterations). Tests are pure readers of the repo per spec acceptance #7 — tempfile crate added as workspace dep for the CLI roundtrip's intermediate file outside the repo.
