Extension Census — ledger

Extracted from repo_files.tsv (curated 3,344-row file census) in /root/troupe-standup.

Rule: basename = final path component; extension = substring after the LAST dot, lowercased; dotfiles (leading dot, e.g. .gitignore, .hermes-tmp.GOYIwZ) and files with no dot are grouped as (none).

Total files: 3344 (matches the 3344 data rows in repo_files.tsv).

Verification notes

• repo_exts.tsv (the existing table) lists 29 rows but carries a duplicated header line and two spurious rows — goyiwz (a parse artifact of the dotfile .hermes-tmp.GOYIwZ) and py"""" (a parse artifact of the escaped wizard-work/beam/CHECK row).
• Existing json (231) vs this table (230): existing classified the dotfile .chk.json as json; under the dotfile rule shown above it is (none).
• Existing (none) (16) vs this table (18): two dotfiles (.chk.json, .hermes-tmp.GOYIwZ) are counted as (none) here.
• py"""" appears in both tables at count 1, so it is a shared value, not a discrepancy; its source row is the escaped beam CHECK row.
• repo_files.tsv records the beam CHECK script twice (rank 1 is an escaped duplicate of rank 620); both rows are included as-is.
