# Mnemonic Correction: GLAMORCUBESFIXPHDN

## Issue
Initial update incorrectly used **GLAMORCUBEPSXHFDN** as the mnemonic.

## Correction
The correct mnemonic is **GLAMORCUBESFIXPHDN**, which represents the alphabetical ordering by single-letter code.

## Letter Order Breakdown

### Correct Order (GLAMORCUBESFIXPHDN)
```
G - Gallery
L - Library
A - Archive
M - Museum
O - Official institution
R - Research center
C - Corporation
U - Unknown
B - Botanical/Zoo
E - Education provider
S - Collecting society
F - Features
I - Intangible heritage group
X - miXed
P - Personal collection
H - Holy sites
D - Digital platform
N - NGO
```

### Why This Order?
The mnemonic follows **alphabetical ordering by single-letter GHCID code**:
- G-L-A-M-O-R-C-U-B-E-S-F-I-X-P-H-D-N

This is NOT the order types appear in tables (which may be semantic/functional), but rather the alphabetical sequence of their codes used in GHCID generation.

## Files Corrected
✅ All occurrences of GLAMORCUBEPSXHFDN replaced with GLAMORCUBESFIXPHDN in:
- AGENTS.md
- schemas/enums.yaml
- src/glam_extractor/models.py
- data/instances/all/README.md
- TAXONOMY_UPDATE_SUMMARY.md

## Verification
```bash
# Confirmed: 0 files with old mnemonic
rg "GLAMORCUBEPSXHFDN" --type md --type yaml --type py

# Confirmed: All key files have correct mnemonic
rg "GLAMORCUBESFIXPHDN" AGENTS.md schemas/enums.yaml
```
