5-5: Content improvements are well-executed.The rewording throughout the document improves clarity and concision. Notable strengths:
- Line 5: Clearer, more direct opening statement.
- Lines 33-37: Refined explanation of zero-dependencies philosophy with added context ("rare chance because in real jobs...").
- Lines 65-66: More pragmatic Data Structures intro that frames efficiency learning within the project's scope.
- Lines 71-84: Added concrete JSON example for indexing structure (helpful for visualization).
- Lines 88-90: Removed verbose code snippet but retained clear explanation of trie performance benefits.
- Line 214: Fixed typo "owning" → "owing".
- Removed sections: Deletion of Storage, Atomic File Write, and Caching sections appropriately reduces noise without losing essential design rationale.

🌐 Web query:
MD036 markdown linting rule emphasis emphasis-as-heading
💡 Result:
Summary — MD036 (emphasis-as-heading)
-
What it checks: Flags single-line paragraphs that consist only of emphasized text (bold/italic) that appear to be section headings — i.e., emphasis used instead of a Markdown heading. [1][2]
-
Why: Headings have semantic meaning and should be used to separate sections instead of emphasis. [2]
-
Example (fails):
My documentAnother section
— Should be:My document
Another section. [1][2]
-
Behavior/details:
- Only triggers for single-line paragraphs made entirely of emphasis; it won’t fire for emphasis inside normal sentences or multi-line emphasized paragraphs. It typically ignores emphasized lines that end with configured punctuation. [1][2]
- Aliases: no-emphasis-as-heading / no-emphasis-as-header. [2][3]
-
Configurable option: punctuation — characters treated as sentence-ending so an emphasized line that ends with one of these is not flagged (default includes: . , ; : ! ? and full-width equivalents). You can disable the rule or adjust punctuation in your markdownlint config. [3][2]
Sources:
[1] MD036 — markdown-lint / Up & Down Press documentation.
[2] Rule MD036 — PyMarkdown Linter docs.
[3] markdownlint default config / gist (shows MD036 punctuation setting and aliases).
Remove the emphasis from the metadata line.
Line 3 contains italicized text (*Author: Ian Chen, Last Update: 2026-01-01*) which triggers the MD036 rule (emphasis-as-heading) since it's a single-line paragraph consisting entirely of emphasized text. Instead of using a setext-style heading (which is meant for actual section headings, not metadata), simply remove the asterisks to display it as plain text: Author: Ian Chen, Last Update: 2026-01-01.

In document/MOTIVATION.md around lines 3 to 3, the metadata line is wrapped in
asterisks causing it to be treated as emphasis (triggers MD036); remove the
leading and trailing asterisks so the line reads as plain text e.g. Author: Ian

Fix hard tabs and indentation depth in table of contents.
The TOC uses hard tabs and inconsistent indentation that violate markdown style rules (MD007, MD010). Markdown lists expect 2-space indentation per level, not tabs.

In document/MOTIVATION.md around lines 8 to 17, the table of contents uses hard
tabs and inconsistent indentation causing markdownlint violations (MD007,
MD010); replace every hard tab with two spaces per list level (use 2 spaces for
first-level bullets, 4 for nested level, etc.), normalize all list markers to
consistent hyphens or asterisks, remove any trailing spaces, and ensure
indentation depth matches each nesting level so the TOC conforms to Markdown
list style rules.
