Instrument
----------
Instrument: STRUC-PERC-I
Version: v2.5.0
Mode: Batch mode
Input family: ABCD charge-boundary ladder encodings
Project phase: Phase 1 — Charge Boundary Classification

Purpose
-------
This report summarizes the first STRUC-PERC-I batch test of the ABCD
Charge Boundary Routing I ladder encodings.

The purpose of this run is not to derive a final law of electric charge.
The purpose is to test whether different encodings of the same verified
Phase 1 charge corpus behave differently as structural ladders.

The central comparison is:

    bare charge-value encodings
    versus
    UNNS route / closure encodings

Input Encodings
---------------
- ABCD_charge_boundary_ladder_signed_charge.csv
- ABCD_charge_boundary_ladder_absolute_charge.csv
- ABCD_charge_boundary_ladder_boundary_route_coordinate.csv
- ABCD_charge_boundary_ladder_closure_class_code.csv
- ABCD_charge_boundary_ladder_closure_state_code.csv
- ABCD_charge_boundary_ladder_route_class_code.csv

Batch Summary
-------------
Total ladders tested: 6
FULL_PERCOLATION:     4
HARD_FRAGMENTATION:   2

Result Table
------------

| Encoding | Verdict | Giant ratio | Isolated | Isolated fraction | κ_connect | n | Interpretation |
|---|---:|---:|---:|---:|---:|---:|---|
| signed_charge | HARD_FRAGMENTATION | 0.857142857143 | 1 | 0.142857142857 | null | 7 | Raw signed electric charge values fragment. Charge value alone does not produce a globally connected structural ladder. |
| absolute_charge | HARD_FRAGMENTATION | 0.75 | 1 | 0.25 | null | 4 | Charge magnitude alone also fragments. Removing sign does not recover structural connectivity. |
| boundary_route_coordinate | FULL_PERCOLATION | 1 | 0 | 0 | 1 | 7 | Detailed UNNS boundary-route ordering fully percolates. The route coordinate connects the charge corpus structurally. |
| closure_class_code | FULL_PERCOLATION | 1 | 0 | 0 | 1 | 7 | Closure taxonomy fully percolates. The corpus becomes connected when organized by closure class. |
| closure_state_code | FULL_PERCOLATION | 1 | 0 | 0 | 0.01 | 4 | Closed/internal/not-closed/constrained/unresolved state ordering fully percolates and connects at the lowest tested scale. |
| route_class_code | FULL_PERCOLATION | 1 | 0 | 0 | 0.01 | 5 | Route-role topology fully percolates and connects at the lowest tested scale. |

Primary Finding
---------------
The batch result separates the ABCD corpus into two clear behavioral groups:

1. Charge-value encodings fragment:
   - signed_charge: HARD_FRAGMENTATION
   - absolute_charge: HARD_FRAGMENTATION

2. UNNS route / closure encodings fully percolate:
   - boundary_route_coordinate: FULL_PERCOLATION
   - closure_class_code: FULL_PERCOLATION
   - closure_state_code: FULL_PERCOLATION
   - route_class_code: FULL_PERCOLATION

The compact result statement is:

    Charge-value space fragments; charge-route space percolates.

Detailed Observations
---------------------

1. Signed charge fragments.
   Verdict: HARD_FRAGMENTATION
   Giant ratio: 0.857142857143
   Isolated vertices: 1
   κ_connect: null
   Interpretation: raw signed charge values are not sufficient to express
   the structural continuity of the corpus.

2. Absolute charge also fragments.
   Verdict: HARD_FRAGMENTATION
   Giant ratio: 0.75
   Isolated vertices: 1
   κ_connect: null
   Interpretation: magnitude-only charge representation does not recover
   percolation. Therefore the failure is not simply a sign artifact.

3. Boundary-route coordinate fully percolates.
   Verdict: FULL_PERCOLATION
   Giant ratio: 1
   Isolated vertices: 0
   κ_connect: 1
   Interpretation: when the corpus is represented as a route through
   external closure, confined fractional coordinate, composite closure,
   boundary absence, and constraint, the topology becomes connected.

4. Closure and route taxonomies fully percolate.
   closure_class_code: FULL_PERCOLATION, κ_connect = 1
   closure_state_code: FULL_PERCOLATION, κ_connect = 0.01
   route_class_code: FULL_PERCOLATION, κ_connect = 0.01
   Interpretation: the structural organization lies in the closure/route
   role of each charge state, not in bare Q/e alone.

UNNS Interpretation
-------------------
The Phase 1 STRUC-PERC-I result supports the working UNNS charge-boundary
hypothesis:

    External observability requires charge-boundary closure.
    Fractional charge is permitted as an internal route coordinate only
    when routed into a confined composite whose external boundary charge
    is integer or neutral.

In this chamber test, the charge corpus becomes structurally connected
only after charge values are lifted into route/closure representation.

This does not yet prove a final law of electric charge. It establishes a
first empirical route-separation result:

    raw charge value is a fragmented projection;
    boundary-route representation is the percolating structure.

Operational Consequence
-----------------------
The next stage should not use signed charge alone as the primary ladder.
Signed charge and absolute charge should remain as control encodings.

The primary encodings for the next chamber stage should be:

    ABCD_charge_boundary_ladder_boundary_route_coordinate.csv
    ABCD_charge_boundary_ladder_closure_class_code.csv
    ABCD_charge_boundary_ladder_route_class_code.csv

Next Step
---------
Combine this STRUC-PERC-I result with the existing STRUC-I v1.0.4 result.
The combined report should compare:

    STRUC-PERC-I: connectivity / fragmentation
    STRUC-I:      admissibility pressure / transitional boundary state
