UNNS Spectral Trajectory Extraction Engine — Pipeline Continuation
Current Project State

The spectral corpus extraction pipeline has now successfully progressed through:

MDB corpus
    ↓
targeted TXT export
    ↓
spectral ladder extraction
    ↓
trajectory normalization
    ↓
κ-grid sweep preparation

The system is now ready for:

STRUC-PERC-I multi-grid stability validation

which is the first rigorous test of:

κ-discretization invariance

inside the UNNS structural regime framework.

Completed Pipeline Stages
1. MDB Corpus Extraction

Source:

SpectralParam table

Targeted exports were performed for:

Corpus Type	ID
Thermal transitions	400, 410, 420, 950, 954
Mechanical	500
Electrical	700
Density	100
TEC	130

The MDB database was filtered and exported into TXT format.

Critical realization:

TXT export alone is sufficient.

Direct MDB access is no longer required for downstream analysis.

2. spectral_ladder_generator.py

Purpose:

TXT export
    ↓
material grouping
    ↓
spectral coordinate sorting
    ↓
ladder extraction

The generator now:

safely parses TXT exports,
detects actual file separators,
groups by oxide/material identity,
sorts spectral coordinates,
emits ordered spectral ladders.

Generated output:

ladders/

Each ladder format:

# UNNS Spectral Trajectory Ladder
# Oxide: Bi2O3
# GlassNo: 493506

# index wt_pct spectral

0 38.40 0.838
1 81.69 6.19
...
3. trajectory_normalizer.py

Purpose:

raw ladders
    ↓
trajectory normalization

The normalizer performs:

duplicate coordinate removal,
coordinate ordering,
discontinuity suppression,
outlier filtering,
sparse-region stabilization,
scale normalization.

Generated output:

normalized_ladders/

These ladders are now structurally admissible for:

STRUC-PERC-I ingestion
4. grid_sweep_runner.py

Purpose:

normalized_ladders/
    ↓
κ-grid replication
    ↓
manual STRUC-PERC-I validation preparation

The runner generates:

grid_runs/

    GRID_A/
    GRID_B/
    GRID_C/
    GRID_D/
    GRID_E/
    GRID_F/
    GRID_G/

Each grid folder contains:

copied normalized ladders,
κ-grid metadata,
STRUC-PERC-I run instructions.
κ-Grid Validation Program
Baseline Refinement Runs
Grid	κ Range	Layers
GRID_A	[0.01, 1.0]	17
GRID_B	[0.01, 1.0]	33
GRID_C	[0.01, 1.0]	65
GRID_D	[0.01, 1.0]	129
Perturbation Runs
Grid	κ Range	Layers
GRID_E	[0.005, 1.0]	65
GRID_F	[0.01, 1.25]	65
GRID_G	[0.001, 2.0]	65
Scientific Goal

The next phase tests whether:

UNNS regime discretization
survives κ-grid refinement.

This directly addresses the major theoretical vulnerability:

possible κ-grid dependence

Critics could otherwise argue:

the observed quantization
is merely a scan artifact.

The current validation program is designed specifically to eliminate that possibility.

Required Next Step
Manual STRUC-PERC-I Grid Validation

For EACH grid:

1. Open STRUC-PERC-I_v2_5_0.html
2. Set:
       κ_min
       κ_max
       κ_points
3. Load ladders from corresponding GRID_X folder
4. Run phase mapping
5. Export regime maps
6. Compare across grids
Primary Stability Metrics

The following quantities must remain structurally stable:

κ-connect thresholds
kapConnect
Regime classifications
CONNECTED
FRAGMENTED
TRANSITIONAL
COLLAPSED
Giant-component evolution
giantRatio trajectories
Structural continuity
ρ continuity
percolation persistence
Expected Theoretical Outcome

If regime structure persists under:

layer refinement,
κ-range perturbation,
scan densification,

then:

UNNS discretization becomes
resolution-independent.

That would strongly support the claim that:

structural regime classes
are intrinsic properties
of admissibility geometry,
not numerical artifacts.
Longer-Term Infrastructure

The current workflow is intentionally manual:

grid_sweep_runner.py
    ↓
manual STRUC-PERC-I execution

This is scientifically preferable during the validation phase because:

regime persistence can be visually inspected,
artifacts are easier to detect,
instability regions become interpretable.

Automation infrastructure:

engine_server.js

may later provide:

Python
    ↔
STRUC-PERC-I

integration, but is NOT required for the current theoretical milestone.

Immediate Continuation

Next operational stage:

normalized_ladders/
    ↓
grid_runs/
    ↓
manual STRUC-PERC-I executions
    ↓
multi-grid regime comparison
    ↓
κ-stability analysis
    ↓
universality validation

This is now the central active research objective.
