Example 143 - The Glyphic-Function Sub-Language: an Audit of the Canonical
Patterns and the Nesting (THOL[...]) That Lifts the Grammar to Context-Free
==============================================================================

The grammar is the only mechanism that modifies coherence, and examples 139-142
characterized the OPERATOR-sequence language L as a regular language (a finite
automaton with capacity lambda=11.56, 9 grammatical role-classes). This example
audits the higher-level "canonical patterns" concept (Bootstrap / Stabilize /
Explore / Propagate, and the named registries scattered across the codebase) and
reconstructs it from the ORIGINAL source -- TNFR.pdf 2.3 "Macros glificas" and
the "Tabla de funciones glificas operativas" -- finding that the original concept
is a genuine SUB-LANGUAGE of nested glyphic functions, richer than the flat code
patterns, whose nesting feature THOL[...] places the full language one level
above L in the Chomsky hierarchy.

The original canonical glyphic functions (TNFR.pdf 2.3)
-------------------------------------------------------
  Activacion simple          AL -> IL -> RA            (stabilized emission that propagates)
  Estabilizacion mutacional  OZ -> ZHIR -> IL          (dissonance transformed into coherence)
  Ciclo regenerativo         NAV -> THOL[ ... ] -> SHA (self-organized node returns to latency)
  Interfaz adaptativa        THOL[ ZHIR -> UM -> NAV ] -> RA (network reorganizes and expands)
  MACRO INIT                 AL -> IL -> UM
  MOD ESTABILIZADOR          OZ -> ZHIR -> IL

The decisive feature the flat code patterns LOST is the NESTING THOL[ body ]:
THOL opens a sub-EPI whose interior is itself a glyphic sub-sequence. That is
exactly operational fractality (U5, nested EPIs). The code-side patterns
(Bootstrap=[AL,UM,IL], Stabilize=[IL,SHA], Explore=[OZ,ZHIR,IL], Propagate/
RESONATE=[RA,UM,RA]) are flat, depth-0, and DIVERGE from the PDF (e.g. the PDF's
MACRO INIT is [AL,IL,UM], not Bootstrap's [AL,UM,IL]).

Doctrine compliance
-------------------
Validity is decided exclusively by the canonical validate_grammar oracle (U1-U6).
The nesting bracket is the canonical THOL sub-EPI boundary (AGENTS.md: THOL
"creates sub-EPIs, fractal structuring"; U5 multi-scale coherence). Nothing is
imposed; the audit and the Chomsky-hierarchy placement are measured/derived.

Three measured results
----------------------
M1 AUDIT. The PDF-original glyphic functions and the code base patterns are ALL
   grammatical FRAGMENTS (0 of 9 PDF macros, 0 of 5 code patterns are valid
   standalone words) -- they are macros meant to be COMPOSED, not sequences. And
   2 of the 10 "concrete" registry sequences in canonical_patterns.py are in fact
   INVALID: therapeutic_protocol starts with EN (not a U1a generator) and
   full_deployment has ZHIR with no prior IL (U4b violated). The code patterns
   diverge from the PDF and dropped the nesting entirely.

M2 COMPOSITION. A fragment becomes a valid word exactly by adding the missing
   grammar boundary: a U1a generator prefix and a U1b closure suffix (plus the
   U4b context a transformer needs). Bootstrap [AL,UM,IL] -> [AL,UM,IL,SHA] is
   valid; the macros compose into larger valid words with this glue. This is the
   PDF's "compose into more complex structures" recovered exactly: the glyphic
   functions are the WORDS, composition is the higher grammar.

M3 NESTING = CONTEXT-FREE (the recovered fractal variable). A well-formed nested
   glyphic function THOL[ body ] (body itself grammar-valid) flattens to a
   grammar-VALID operator stream -- the regular layer of ex 139-142 is preserved.
   But the bracket structure is a Dyck language: the number of nesting tree shapes
   with n THOL nodes is exactly the Catalan number C_n (1,1,2,5,14,42,...), and
   the nesting depth is unbounded and balanced, so the bracketed glyphic-function
   language is CONTEXT-FREE and NOT regular (pumping lemma). The bracket depth IS
   the nested-EPI fractal scale (U5). So operational fractality U5 is precisely
   the feature that lifts the glyphic language one level above the regular
   operator grammar L.

Honest scope
------------
This is standard formal-language theory (Dyck language, Catalan numbers, the
pumping lemma, the Chomsky hierarchy) applied to the canonical grammar U1-U6 and
the canonical THOL nesting recovered from TNFR.pdf. It is an AUDIT plus a
CHARACTERIZATION: it documents the drift of the code-side "canonical patterns"
from the original glyphic-function concept and locates the full sub-language at
the context-free level, with nesting depth = the U5 fractal scale. It is not new
mathematics and closes no open problem. It does not modify the operator
definitions or the grammar; it does flag two invalid registry sequences for
future cleanup.
