Issues#

Critical#

None found.

High severity#

  • [qe-math-003] — \begin{array}{c}...\end{array} (with \left[ \right]) used everywhere instead of \begin{bmatrix}. Example: lectures/permanent_income_dles.md:161, :163, :165, :166, :170-173, :256-260. Count: ~10 occurrences.

  • [qe-math-010 (proposed)] — Bare E_0 / E_t instead of \mathbb{E}_0. Example: lectures/permanent_income_dles.md:70, :73, :129. Count: ~4 occurrences.

Medium severity#

  • [qe-writing-005] — **Technology:**, **Information:**, **Preferences:** use bold for labels rather than definitions.

Low severity#

  • [qe-writing-001] — A few multi-sentence paragraphs, e.g. L46-48, L268-271.

  • [qe-fig-005] — Figures lack :name: fig-... fields.

Strengths#

  • Title in Title Case (qe-writing-006).

  • Section heading in sentence case (qe-writing-006).

  • \begin{bmatrix} is used in some places (L140, L266) — file knows the right convention.

  • Equation references via {eq} (qe-math-007) and labelled {math} blocks.

  • Unicode Greek in code (qe-code-002).

  • Install cell at top with hide-output (qe-code-003).
