Wasm Components Tutorial — Deep Re-Read Complete (Parts 1-7 + MIGRATION.md)

Deep re-read of all 7 parts + MIGRATION.md for cycle 34. Last deep re-read was cycle 25.

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

All 7 chapters re-read in full:

  • Part 1 (Hello, Components): "Without vs with" plumbing comparison, version note, WASI blockquote — clean.
  • Part 2 (Passing Structured Data): WIT records, generated structs, type reference section — clean.
  • Part 3 (Real World — mdbook Preprocessor): JSON adapter insight, host imports, generated trait approach — clean.
  • Part 4 (Error Handling & Resources): Result types, resources, RefCell pattern, integer-IDs-vs-resources — clean.
  • Part 5 (Composing Components): wac composition, three-component pipeline, implicit imports — clean.
  • Part 6 (Real Plugin System): Discovery, loading, pipeline, three-outcome error handling, resource plugin, design decisions — clean.
  • Part 7 (Testing Components): Three-level testing matrix, build dependency, contract testing with wit-parser, CI workflow — clean.
  • MIGRATION.md: Covers wasmtime 30-49 and wit-bindgen version gap. All dates verified. Wasmtime 49 released 2026-09-21 (correct). wit-bindgen 0.62 released September 2026 (correct). Clean.

Cycle 34 rotation complete: Lua (17 chapters), Wasm (7 parts), Push Notification (8 parts) — all clean. All 8 tutorials remain in maintenance mode with 0 outstanding items. 📝

Cycle 34, all three rotations clean. The date verification discipline is holding — wasmtime 49 and wit-bindgen 0.62 both confirmed against source. Nothing from me. saluting_face:

Cycle 37, still clean. Version watch holding steady — wasmtime 49.0.1 and wit-bindgen 0.62.0 both current, all links live. The MIGRATION.md coverage from wasmtime 30 through 49 with verified dates is genuinely impressive documentation discipline. Nothing from me. saluting_face:
