[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.PURPOSE.DEFINITION.3-6-1] [SSI:TITLE=WHAT_IS_SSM;AUTHORITY=PRIMARY;REF=3-6-1] [SSM:SECTION=DEFINITION;INTENT=DEFINITION;ABSTRACTION=HIGH]

3.6.1 — What SSM Is

Section Semantic Metadata (SSM) declares the behavioural contract of a section.

It defines how the content may behave when it is:

  • retrieved
  • interpreted
  • combined
  • reused by systems or AI agents

SSM answers one—and only one—question:

“How may this section be used safely?”

SSM is declarative, binding, and enforceable.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.PURPOSE.RATIONALE.3-6-2] [SSI:TITLE=SSM_IS_MANDATORY;AUTHORITY=PRIMARY;REF=3-6-2] [SSM:SECTION=CONCEPT;INTENT=RATIONALE;ABSTRACTION=HIGH]

3.6.2 — Why SSM Is Mandatory

Without SSM, systems must infer:

  • why content exists
  • whether it is safe to act on
  • whether it is descriptive or executable

Inference causes:

  • hallucinated procedures
  • unsafe summaries
  • instruction leakage
  • misaligned answers

SSM exists to eliminate inference entirely.

A section without SSM is not semantically safe.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.DIMENSIONS.DEFINITION.3-6-3] [SSI:TITLE=SSM_DIMENSIONS;AUTHORITY=PRIMARY;REF=3-6-3] [SSM:SECTION=DEFINITION;INTENT=DEFINITION;ABSTRACTION=HIGH]

3.6.3 — What SSM Declares

Every SSM anchor declares three mandatory dimensions:

  1. SECTION — what kind of semantic unit this is
  2. INTENT — why the section exists
  3. ABSTRACTION — how close it is to execution

These dimensions are orthogonal, mandatory, and binding.

Together they form the behavioural contract of the section.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.SECTION.DEFINITION.3-6-4] [SSI:TITLE=SECTION_DIMENSION;AUTHORITY=PRIMARY;REF=3-6-4] [SSM:SECTION=DEFINITION;INTENT=DEFINITION;ABSTRACTION=HIGH]

3.6.4 — SECTION Dimension

SECTION declares the structural kind of semantic unit.

It answers:

“What kind of semantic unit is this?”

SECTION is:

  • structural
  • taxonomic
  • content-type oriented

SECTION is not intent, abstraction, or authority.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.SECTION.RATIONALE.3-6-5] [SSI:TITLE=SECTION_IS_AUTHORITATIVE;AUTHORITY=PRIMARY;REF=3-6-5] [SSM:SECTION=CONCEPT;INTENT=RATIONALE;ABSTRACTION=HIGH]

3.6.5 — Why SECTION Is Authoritative

SECTION types are closed and versioned to ensure:

  • deterministic chunking
  • safe reuse
  • predictable routing
  • enforceable validation

Inventing SECTION types breaks semantic determinism.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.SECTION.DEFINITION.3-6-6] [SSI:TITLE=CANONICAL_SECTION_TYPES;AUTHORITY=PRIMARY;REF=3-6-6] [SSM:SECTION=DEFINITION;INTENT=DEFINITION;ABSTRACTION=HIGH]

3.6.6 — Canonical SECTION Types

Authors must select exactly one SECTION:

  • DEFINITION
  • CONCEPT
  • COMPONENT
  • RULE
  • PROCESS
  • PROCEDURE
  • MODEL

Mixing SECTION types is a semantic fault.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.INTENT.DEFINITION.3-6-7] [SSI:TITLE=INTENT_DIMENSION;AUTHORITY=PRIMARY;REF=3-6-7] [SSM:SECTION=DEFINITION;INTENT=DEFINITION;ABSTRACTION=HIGH]

3.6.7 — INTENT Dimension

INTENT declares why the section exists.

It governs behaviour across:

  • summarisation
  • extraction
  • reuse
  • response composition

INTENT must survive rewriting and re-expression.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.INTENT.DEFINITION.3-6-8] [SSI:TITLE=CANONICAL_INTENT_TYPES;AUTHORITY=PRIMARY;REF=3-6-8] [SSM:SECTION=DEFINITION;INTENT=DEFINITION;ABSTRACTION=HIGH]

3.6.8 — Canonical INTENT Types

Authors must select exactly one INTENT:

  • DEFINITION
  • PURPOSE
  • RATIONALE
  • MODEL
  • PROCEDURE
  • CONSTRAINT
  • APPLICATION
  • COMPARISON
  • GOVERNANCE
  • STATUS

Mixing intents is a semantic fault.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.DIMENSIONS.MODEL.3-6-9] [SSI:TITLE=ORTHOGONAL_DIMENSIONS;AUTHORITY=PRIMARY;REF=3-6-9] [SSM:SECTION=CONCEPT;INTENT=MODEL;ABSTRACTION=HIGH]

3.6.9 — Orthogonality of Dimensions

[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.CONTRACT.CONSTRAINT.3-6-10] [SSI:TITLE=THE_SSM_CONTRACT;AUTHORITY=PRIMARY;REF=3-6-10] [SSM:SECTION=CONCEPT;INTENT=CONSTRAINT;ABSTRACTION=HIGH]

3.6.10 — The SSM Contract

Once declared, SSM is enforced.

All content must:

  • match its SECTION
  • satisfy its INTENT
  • remain within its ABSTRACTION

Violations are semantic errors, not stylistic ones.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.SUMMARY.BEHAVIOUR.3-6-11] [SSI:TITLE=SUMMARY;AUTHORITY=SECONDARY;REF=3-6-11] [SSM:SECTION=SUMMARY;INTENT=SUMMARY;ABSTRACTION=HIGH]

3.6.11 — Summary

Section Semantic Metadata (SSM) defines the behavioural contract of a section.

By declaring SECTION, INTENT, and ABSTRACTION explicitly, SSM:

  • eliminates inference
  • prevents behavioural leakage
  • enables safe retrieval
  • constrains agent behaviour

SSM is the mechanism that makes semantic content governable.


[SSB:THEORY.SEMANTIC_BINDING.SECTION_SEMANTIC_METADATA.STATUS.DECLARATION.3-6-12] [SSI:TITLE=STATUS;AUTHORITY=SECONDARY;REF=3-6-12] [SSM:SECTION=STATUS;INTENT=STATUS;ABSTRACTION=LOW]

3.6.12 — Status

Section Semantic Metadata (SSM) is active, mandatory, and authoritative.

All systems must enforce SSM as the behavioural contract governing retrieval, interpretation, composition, and execution safety.

Without SSM, section behaviour becomes inferential and unsafe.
