- new handlers/routes: casecheck (key_header: "Idempotency-Key", the
README's documented shape) and patha/pathb (include_body: false,
same key, different routes)
- 18g: capitalised key_header + capitalised wire header must still
dedupe (exec count, not status, is the load-bearing assertion --
pre-fix both calls answer 200 either way, but the handler reruns)
- 18h: same key on two different routes with include_body:false must
answer 200 then 422 (a digest mismatch, same as a body mismatch),
never replay route a's body under route b
- both legs run on a FRESH restart of the same binary, not piled onto
18a-18f's already-loaded server -- doing so measurably raised how
often this run hit the pre-existing, out-of-scope C-runtime
arena-allocator race (confirmed by gdb backtrace: SIGSEGV inside
wo_str_new, unrelated to this file's own .wo logic)
