18-section interactive course teaching compiler construction in Rust
using nom. Covers MiniLisp parsing, AST design, semantic analysis,
and C code generation. All sections stubbed; one nbd task ticket per
section plus a project ticket (67e284) tracking completion.

Replaces the stub in Section 2 with full prose covering:
- State space definition (finite vs countably infinite)
- Transitions as directed, probability-labelled edges
- ASCII state-transition diagram for the weather model
- Absorbing, transient, and recurrent state classification
Full Exercise 3 — Bigram Text Generator section replacing the stub:
- Setup instructions (cargo new, cargo add rand)
- Starter code skeleton with BigramModel struct
- Step 1: tokenize corpus with split_whitespace + to_lowercase
- Step 2: build transition table via windows(2) with count tracking
- Step 3: integer weighted sampling helper (sample_weighted)
- Step 4: generate implementation with dead-end handling
- Step 5: run the generator with the Alice corpus and seeded RNG
- Step 6: guidance for trying a larger Project Gutenberg corpus
- Full reference solution in a collapsible details block

Replace stub with full prose covering the stationary equation,
long-run frequency interpretation, irreducibility and aperiodicity,
a worked 2×2 analytical solution for the weather chain, and a power
iteration pseudocode + Rust sketch.
Replaces the stub with full lesson content:
- Defines the transition matrix P[i][j] and stochastic matrix constraints
- Derives multi-step probabilities via π_k = π₀ · P^k
- Works through the 2-state weather chain by hand (1- and 2-step calculations)
- Bridges to §9 stationary distributions
- Words as states paragraph
- Bigrams and transition tables explanation
- Worked bigram example with two-sentence corpus and transition table
- Why generated text sounds locally plausible but globally incoherent
- Order-n chains and the coherence/novelty tradeoff
