Issues#

Critical#

None found.

High severity#

  • W3 — Multiple H2 sections in Title Case. Examples: “## Example: The Money Multiplier in Fractional Reserve Banking” (line 118), “## Example: The Keynesian Multiplier” (~280), “## Example: Interest Rates and Present Values” (~438). Count: 3+ section headings.

  • [qe-fig-001] — figsize= overrides on lines 51, 932, 994, 1113. Count: 4 occurrences.

  • [qe-fig-006] — Axis labels with uppercase first letter outside acronyms. Examples: “Present Value, \(p_0\)” (lines 709, 736, 758), “Number of banks \(N\)”, “Marginal propensity to consume \(b\)”, “Cumulative deposits”, “Percentage error (%)”. Count: 5+ occurrences.

Medium severity#

  • W1 — Several multi-sentence paragraphs throughout.

  • M12 — \begin{aligned} \begin{split}...\end{split}\end{aligned} (line 616) — using split inside aligned is unusual; should be just aligned.

  • [qe-fig-003] — ax.set_title(f'An Increase in {param} on Output') (line 948) — Title Case title outside exercise context.

Low severity#

  • W7 — Mid-sentence capitalization inconsistencies.

  • [qe-fig-005] — No figures use {figure} directive with :name:.

Strengths#

  • H1 Title Case OK.

  • {math} labels and {eq} refs used.

  • Bold for definitions (multiplier, money multiplier, etc.).

  • Solutions gated, dropdown, linked.
