loldle.net's classic-mode bundle has two record shapes — older champions carry _id/championId, newer ones (Bel'Veth, K'Sante, Nilah, …) don't. The regex required those leading fields, silently dropping anyone added since 2022. Make _id/championId optional and non-capturing, and drop them from the output record (the bot never read them anyway). Champion count: 169 → 172; guessing /loldle k'sante, /loldle bel'veth, /loldle nilah now resolve correctly.

/**
|
|
* @file Rebuilds src/modules/loldle/champions.json from loldle.net's JS
|
|
* bundle. The bundle embeds the full champion array in plaintext. Records
|
|
* have two shapes (older champions carry _id/championId, newer ones don't);
|
|
* both shapes share the gameplay fields: championName, gender, positions,
|
|
* species, resource, range_type, regions, release_date — the only fields
|
|
* the bot consumes, so we keep just those.
|
|
*
|
|
* The bot imports the resulting JSON directly via `with { type: "json" }`.
|
|
*
|
|
* Usage: node scripts/scrape-loldle-data.js
|
|
* Schedule: weekly via .github/workflows/scrape-loldle-data.yml
