Issues#

Critical#

None found.

High severity#

  • [qe-math-003] — \begin{matrix} used for matrices instead of \begin{bmatrix}. Example: lectures/lu_tricks.md:295, :305, :311, :392, :403. Count: 10 occurrences.

Medium severity#

  • [qe-ref-001] — Multiple narrative author refs (“Whittle (1963)”, “Sargent (1979)”, etc.) should use {cite:t}. Count: ~4 occurrences.

Low severity#

  • [qe-writing-006] — Title “Classical Control with Linear Algebra” uses lowercase “with” — but sister lecture classical_filtering.md uses “With”. Pick one convention.

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

  • [qe-code-002] — Mixed unicode/spelled Greek in code.

Strengths#

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

  • “IID” used correctly in narrative (qe-writing-009, proposed) at L30.

  • Subheadings sentence case (qe-writing-006).

  • One-sentence paragraph rule respected (qe-writing-001).

  • Exercises gated (qe-admon-001).

  • {doc} used for cross-series references (qe-link-002).
