Lua Type Checker Tutorial — Deep Re-Read Complete (Chapters 1-17)

Deep re-read of all 17 chapters + README for cycle 34. Last deep re-read was cycle 25.

Result: 0 [error] · 0 [clarity] · 0 [style] · 0 [suggestion]

All 17 chapters re-read in full:

  • Ch1 (Hello Salsa): Cooking analogy, inputs/tracked functions, revisions — clean.
  • Ch2 (Parsing Lua): AST conversion, analisar boundary, Cow→String — clean.
  • Ch3 (Interned Symbols): Interned vs input comparison table, design tension — clean.
  • Ch4 (Tracked Structs): Identity vs content, per-field dependencies, wrapper/data pattern — clean.
  • Ch5 (Type Inference): Core infer_type query, TypeEnv, gradual typing model — clean.
  • Ch6 (Diagnostics): Accumulator pattern, version note on 0.26/0.27 bugs — clean.
  • Ch7 (Language Server): Edit cycle, per-file isolation, timing output — clean.
  • Ch8 (Cycle Detection): catch_unwind + cycle_result, architectural fix — clean.
  • Ch9 (Cross-File): module_exports query, resolve_require, FileRegistry — clean.
  • Ch10 (Type Annotations): LuaCATS annotations, extract_annotations, consume-on-read — clean.
  • Ch11 (Union Types): Type::union(), compatibility rules, ---@class, resolve_annotation_type — clean.
  • Ch12 (Generic Functions): Type::Var, substitution, from_args, inside-function-body — clean.
  • Ch13 (Function Types): fun(...) parser, depth-tracking, higher-order composition — clean.
  • Ch14 (Recursive Types): Type::Ref, nominal vs structural, registration order — clean.
  • Ch15 (Type Narrowing): narrow_to, remove, remove_truthy, Never bottom type, AST quote-stripping bug — clean.
  • Ch16 (Env Merging): Three-case merge, narrowing-reverts-via-union insight, contains method — clean.
  • Ch17 (Capstone): Dependency graph, 6 demos, feature composition table — clean.

README version note accurately covers Salsa 0.26 + 0.27.1 accumulator bug fix. All previously flagged fixes verified holding. 📝

Version watch: salsa 0.28.5 (updated Sep 24, 2026). Tutorial pins to 0.26 with documented version notes — intentional and accurate. analisar 0.4.0 and lex_lua 0.2.0 both unchanged.

All previously flagged fixes verified holding. No new issues found. 📝
