RNX-130Content Syntactics & Token Efficiency
Read what these checks mean, why they matter and which evidence they concern. Each ID below keeps its canonical place in the RNX hierarchy.
These are free learning summaries, not full technical tests or an industry certification. Specialized checks apply only to the relevant feature. Experimental labels are preserved from the canonical source.
RNX-131 · Deterministic Information Topology
RNX-131.T001
Primary subject heading
core readiness
Give the page a clear main subject heading.
Why it matters. Readers should quickly understand what the page is about.
Illustration — fictional. Only Welcome appears above unrelated blocks.
When it applies. Inspected target: main heading. Use this check only when that object or feature exists in the review scope; provider-specific checks require that provider's integration. Missing evidence remains unknown.
RNX-131.T002
Heading relationship
core readiness
Arrange headings so their levels reflect the content's structure.
Why it matters. Reading tools use those relationships to help people move around.
Illustration — fictional. A visual subsection is marked as a peer topic solely for font styling.
When it applies. Inspected target: heading outline. Use this check only when that object or feature exists in the review scope; provider-specific checks require that provider's integration. Missing evidence remains unknown.
RNX-131.T003
Heading visibility parity
core readiness
Use headings for genuine visible sections.
Why it matters. Hidden search phrases are not a useful outline for readers.
Illustration — fictional. Hidden keyword block falsely claims unrelated services.

RNX-131.T004
Main landmark
core readiness
Identify the main content area in the page structure.
Why it matters. This helps assistive tools separate the article from repeated menus.
Illustration — fictional. Several indistinguishable main regions compete.
When it applies. Inspected target: main landmark. Use this check only when that object or feature exists in the review scope; provider-specific checks require that provider's integration. Missing evidence remains unknown.
RNX-131.T005
Navigation landmark naming
core readiness
Give different navigation areas clear names.
Why it matters. Readers using assistive tools need to distinguish a main menu from other link groups.
Illustration — fictional. Two different navigation sets both expose only Navigation.
When it applies. Inspected target: navigation region set. Use this check only when that object or feature exists in the review scope; provider-specific checks require that provider's integration. Missing evidence remains unknown.
RNX-132 · Answer-First Formatting
RNX-132.T001
Answer presentation fitness
core readiness
Present a direct, accurate answer in a form that fits the question.
Why it matters. A short list, explanation or table should make the answer easier to use.
Illustration — fictional. Bullets detach eligibility exception from the offer it limits.
When it applies. Inspected target: answer passage. Use this check only when that object or feature exists in the review scope; provider-specific checks require that provider's integration. Missing evidence remains unknown.
RNX-133 · Compositional Retrieval Structuring
RNX-133.T001
Segment context retention
Experimental — not an established ranking requirement
For content retrieved in pieces, retain the context needed to understand each piece.
Why it matters. An isolated sentence can lose an important condition.
Illustration — fictional. A retrieved passage says 49 but leaves out the product and currency needed to interpret it.
When it applies. Inspected target: retrieved segment. Use this check only when that object or feature exists in the review scope; provider-specific checks require that provider's integration. Missing evidence remains unknown.
