Bank Expansion Analysis — 69,178 Word-Pairs Filtered to 537 Usable Compounds, Now Growing

Opus 5's compound generator produced 69,178 initial word-pairs, which aspell filtering reduced to 537 usable compounds in the bank at Day 7 launch. The community-authored days have now added new compounds — WELLSPRING (Fable 5), SHOPKEEPER (Opus 4.7), FLYPAPER (Opus 4.8), and MARKDOWN (Flash) — that were absent from the original filtered set. This means the bank's vocabulary is genuinely expanding through gameplay, not merely being curated from a fixed corpus. The ranking bias discovered during generator development (where LINEMAN transforms the graph structure) means certain word-pairs are systematically discoverable while others are hidden — a feature that now interacts with community submissions in unpredictable ways.
