mrwulf 4a37da8fd9 Curriculum: the ratchet rule, the four-tier reality, and lecture 9 (dogfood)
The notebooks now carry the same didactic contract as the companion book
(the "ratchet rule", stated in the course map): every load-bearing idea
runs twice - napkin scale, then real scale - and every pair is EXECUTABLE
in the notebook, not narrated.

- Lecture 1: the truth boundary updated to the proven four-tier apex,
  with the what-is-still-NOT-proven list (SHA-512, parsers, signing,
  wallets) given equal weight.
- Lecture 2: napkin/real scoring pair - a two-certificate toy card
  scored in your head, then the shipped sixteen-certificate R4 fixture
  through the same function, residual blockers and per-tier boundary
  axioms printed.
- Lecture 6: new split-view section. A runnable equivocation drill:
  pin a two-leaf view, grow it honestly with a consistency proof, then
  present a forged same-size root and watch the pin store name the
  attack. Real-scale pointers to --sth-store, log-consistency,
  log-audit, and the freshness policy; a new exercise asks students to
  construct the lie a size-only anchor check would miss.
- Lecture 7: the wallet gate now swings BOTH ways on real evidence -
  a partial card denied at R3, the shipped R4 card allowed - both
  runnable.
- Lecture 8 capstone: "design R4" became "audit R4": read the shipped
  card like an auditor, then design the R5 discharge plan (parser
  specs, verified SHA-512, signing-side, per-fork production-path
  mapping).
- NEW Lecture 9, "Eat Your Own Dogfood": the honest coverage ledger of
  the proven-path verifier; a napkin PEM decode (the fixed 12-byte
  Ed25519 SPKI prefix, read with your eyes) paired with the mechanical
  extraction; live backend dispatch; the fail-closed
  --require-verified-verifier policy; and the hybrid-PQC section -
  proven-classical Ed25519 plus a required-but-honest ML-DSA slot
  ("blockers get fixed; placeholders get trusted").

Every code cell of the changed notebooks was executed end-to-end before
committing (outputs stripped per house rules). 49/49 tests green with
the notebook inventory updated.
