Subject: [PATCH 4/6] fix(docs): repair markdown code-fence structure; converge
 projections with 1f0add99

- Normalized corrupted fences (4-backtick openers, indented closers, orphan
  pairs) in docs/architecture/decisions/002-railway-pattern.md and
  docs/api/core.md so embedded python blocks extract cleanly
  (markdown-code gate: 41 -> 0 findings)
- prettier reflow via canonical make fmt (markdown-format: 9 -> 0)
- gen fixed point against integration tip 1f0add99

From 7bccc2b19263273c46eb41d88d967ab7b11cd6b8 Mon Sep 17 00:00:00 2001
From: Marlon Costa <marlon.costa@datacosmos.com.br>

Subject: [PATCH 6/6] fix(tests): test facades declare one nested Tests MRO
 (NS-STRUCT-001)

The new namespace structure rule requires each test facade to declare
exactly one nested class composing the production letter. The five
test facades carried empty helper nesteds plus a second Tests class;
collapsed to the canonical single Tests MRO shape. Full check (19
gates) and test suite green locally.
