…abets New /alphabets page driven by the generated alphabet_index.json (from DasherCore's Scripts/generate-alphabet-index.py): all 474 alphabets with search + filters (writing system, direction, corpus tier), RTL and script badges, lang codes, and data-issue flags. The index is a single generated artifact shared with the engine's data QA. Downloads page: v6 ships every alphabet built in — the hand-maintained per-language download list (many stale filenames) is gone. Replaced with a browse link to /alphabets, kept training texts and the Dasher 5 archive, and rewrote the install instructions for CUSTOM alphabets only (correct v6 user dirs).

116 alphabets carry duplicate symbol definitions (autoconversion-era case groups on caseless scripts, shared Mandarin tone outputs); the index now flags them and the card warning tooltip lists all flags. Signed-off-by: will wade <willwade@gmail.com>

What
/alphabetspage driven bysrc/data/alphabets.json— a generated artifact (DasherCoreScripts/generate-alphabet-index.py) covering all 474 alphabets: search, filter by writing system (48 scripts), direction (22 RTL sets), and corpus tier (maintained / WorldAlphabets / legacy). Lang codes for 456/474; data-issue flags where a declared direction contradicts the script.Why
Dasher v6 bundles the full alphabet corpus; the old page implied people needed to download files to get their language. The catalogue turns the same data the engine QA uses into the public "what languages does Dasher support?" answer.
Regeneration
alphabets.jsonis generated upstream (DasherCore) — refresh by copyingData/alphabets/alphabet_index.jsonafter alphabet changes. CI hook to automate that tracked separately.DCO signed.
