Tier 3

Definition​

Tier 3 is the SI correspondence layer of Length–Mass Reduction.

It concerns the mapping between structural quantities and standard SI representations through ℓm-reduction and related correspondence procedures.

Tier 3 does not govern Tier 1.

Tier Placement​

Primary tier: Tier 3

Role: SI correspondence

Tier 3 belongs to correspondence, comparison, and dimensional translation between LMR structure and standard representations.

Source​

Primary source: Tier 3 notes, correspondence work, and declared ℓm-reduction analysis

Authority level: Working or supplemental unless incorporated into a formal paper sequence

Tier 3 material may clarify how LMR relates to standard SI descriptions, but it does not alter the foundational codex.

Function in LMR​

Tier 3 provides a controlled way to compare LMR structural quantities with standard dimensional and SI representations.

It functions in:

  • ℓm-reduction
  • SI correspondence
  • dimensional comparison
  • measurement-chain analysis
  • bridge evaluation
  • identification of representation-dependent artifacts
  • external comparison without modifying Tier 1

Tier 3 is where correspondence questions belong.

Allowed Use​

Tier 3 may be used to compare LMR quantities with SI quantities when explicitly declared.

It may also be used to analyze dimensional reductions, measurement conventions, and correspondence mappings.

Prohibited Misuse​

Tier 3 must not be treated as:

  • Tier 1 authority
  • foundational grammar
  • proof that SI quantities are primitive in LMR
  • permission to import standard dynamics into Tier 1
  • a replacement for the codex sequence
  • a source of new foundational corridors

Tier 3 correspondence must not be read backward into Tier 1.
