bi-16 step 03 — Notebook, matrix, and an honest assessment

Goal

Produce the three analytical artefacts, and assess yourself against the mastery criteria without flattering the result.

Tasks

  1. Complexity notebook (§46). All twelve entries. For each, classify the complexity as essential architecture, production hardening, or accretion, and defend it with evidence — a commit message, an issue, a test that exists only because of a specific bug. Guessing is not classification.

  2. Comparison matrix (§47). Seven rows — mini-react, React, mini-vue, Vue, signals, Redux, and Blink style invalidation — across ten axes. Fill it from your own implementations. Never reduce it to "which is faster."

  3. Design challenges (§48). For each of the seven, state constraints, invariants, and failure modes.

  4. The eight patterns. Write each in your own words with one example from each strand. If you cannot produce a browser example and a framework example, you have not yet earned the pattern.

  5. Mastery criteria. Go through the list honestly. Where the toolchain blocked a criterion — the upstream Chromium change — say so explicitly rather than quietly dropping it, and record what remains to be done.

Done when

  • Twelve notebook entries, each classified and defended with evidence
  • Matrix complete, including the Blink row
  • Seven design challenges answered
  • Mastery checklist completed honestly, with gaps named
