#75's block-name gate (sentinel-name join, 27 distinct names) is corpus-only because the canonical fixtures carry no blocks; a test fails the moment fixtures gain one. Teach examples/build_fixtures.rs to emit a BLOCK_HEADER + BLOCK sentinel pair (including an anonymous *D-style name with suffix) across the writable bands, bump the census pins, and the join gate moves into CI. Also: R13/R14 block names stay unresolved (no locatable handle stream) — pinned by a test that fails the day it becomes locatable.
