🏙️ Markup guidelines to be used in documents shared between humans and LLM.

📖Unrestricted, optimized for LLM processing

2️⃣CONTEXT

🏙️The ◈Sysjet Markup Language◈ (🏷️SJTL) is an editor-independent UTF-8 document convention designed for structured Human/LLM collaboration.

🟦In this document, SJTL markers are used demonstratively. Descriptive explanations follow standard natural language unless explicitly marked as examples (🔎).

🟦SJTL encodes structural roles and semantic invariants using a restricted set of non-ASCII UTF-8 glyphs placed at deterministic positions in text.

🟦Primary design priorities (in order):

🔹1▸Deterministic interpretation by LLM systems

🔹2▸Direct human readability

🔹3▸Minimal dependence on editor-specific formatting

🟦Each paragraph or paragraph block begins with a semantic marker that defines its structural role. Meaning does not depend on styling, indentation, or external markup syntax.

🟦SJTL avoids overloading ASCII characters with multiple contextual meanings and avoids reliance on Markdown, HTML, or proprietary formatting rules.

📝SJTL documents are plain UTF-8 text and require no pre-processing beyond standard tokenization.

1️⃣SJTL GUIDELINES

2️⃣SYNTAX

🟦The SJTL document is a UTF-8 text composed of Paragraph Separators (PS).

🟦📍◈Paragraph Block◈▸A Paragraph Block consists of one, two or three (1-3) paragraphs.

🟦Each Paragraph Block MUST begin with a primary Semantic Marker (UTF-8 glyph). Any interruption by a different marker resets inheritance.

🟦The first glyph of a Paragraph Block uniquely determines its structural role.

🟦Semantic meaning MUST NOT depend on marker inheritance. Each Paragraph Block is structurally independent.

🟦Multi-line content under a single marker MUST remain within a single Paragraph Block (no implicit continuation).

🟦In case of ambiguity:

🔹1▸Paragraph Block marker determines primary role.

🔹2▸Inline markers refine local semantics.

🔹3▸Paragraph Block marker overrides inline markers.

2️⃣INLINE MARKERS

🟦Inline markers provide local semantic refinement within a paragraph block.

📝Inline markers MUST be balanced and MUST NOT overlap.

📝Nested inline markers MUST close in reverse order.

3️⃣INLINE SEPARATORS

● ▸ Neutral cell or element separator

▸ ▸ Relational separator (name▸description, symbol▸meaning, before▸after)

▢ ▸ Explicit blank separator

3️⃣INLINE HIGHLIGHTS

◈ ▸ Discourse emphasis

◇ ▸ Quote, citation, extract

◆ ▸ Structural invariant

2️⃣PARAGRAPH MARKERS

🟦Paragraph Block markers appear at the beginning of paragraph blocks only.

3️⃣STRUCTURAL

📜▸ Document

1️⃣▸ Header level 1

2️⃣▸Header level 2

3️⃣▸ Header level 3

4️⃣▸ Header level 4…

📝IMPORTANT: The glyphs 1️⃣ 2️⃣ 3️⃣ 4️⃣ 5️⃣6️⃣… denote structural header levels only. They MUST NOT be interpreted as ordinal increments or list numbering.

3️⃣LISTS

🔷❗ Do NOT use editor or language-defined lists (eg

  • in HTML).

    📝Separate list items with paragraph separators (PS). Precede each list level with🔹as follows:

    🔹 ▸ Level 1 list item

    🔹🔹 ▸ Level 2 list item

    🔹🔹🔹 ▸ Level 3 list item…

    📝Ordered lists MUST use 🔹n▸ format (🔎 🔹4▸)

    3️⃣SEMANTIC

    🟦 ▸ Statement: definition, proposition, theorem, hypothesis

    🟦🟦 ▸ Derived statement

    🔷 ▸ Discussion, argument, proof, algorithm

    🔷🔷 ▸ Derived discussion

    🔵 ▸ Discourse: introduction, context, conclusion

    📌 ▸ Appended comment

    📝 ▸ Design note, implementation rule, hint, applicability

    🔎 ▸ Example

    📢 ▸ Important statement

    🔄️ ▸ Dialog

    📚 ▸ References

    🗿 ▸ Archetype, LLM field reporting

    🏙️ ▸ Descriptive overview

    #️⃣ ▸ Tabular group

    ⬜ ▸ Blank; insertion anchor.

    2️⃣END MARKER

    ⬛ ▸ Scope termination marker. End of paragraph, section.

    📝⬛ explicitly closes table groups, discussions, or structural blocks when required for clarity.

    2️⃣COMPLEMENTARY MARKERS

    🟦Complementary markers are semantic markers that describe specific content. They appear at the beginning of paragraphs or inline.

    📍 ▸ Name, name of .

    🏷️ ▸ Tag (2-5 Uppercase-numeric designator)

    🗝️ ▸ Key words, field, context, topic

    🌐 ▸ URL

    📧 ▸ Email address

    📅 ▸ Date, YYMMDD format for day, or YYYY for years.

    ✒️ ▸ Author, creator

    ✏️ ▸ Collaborator, assistant, contributor

    📖 ▸ Access, share permission, open

    ❓ ▸ Speculative, uncertain, question, puzzle

    ❗ ▸ Definitive, final, certain, terminal

    Ⓜ️ ▸Model, LLM

    2️⃣TABLE GROUPS

    🟦A table group begins with #️⃣ and MUST terminate with ⬛.

    🟦Row 1 follows the #️⃣marker. Rows 2, 3… are list items (🔹)

    🟦Within a table group, ● and ▸ are interpreted exclusively as cell separators.

    🟦The ⬛ end marker terminates the current structural scope. No semantic carryover is permitted beyond ⬛.

    📝Do NOT use Markdown, HTML, or editor-defined table formats.

    📝Avoid text wrapping inside table rows.

    📝Referents use [row#column] format:

    🔹[a#b] ▸ cell

    🔹[a#] ▸ row

    🔹[#b] ▸ column
