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