Gotchas

Before changing a file listed below, read its gotcha: ref/<id>.md in this skill (or kb_gotcha <id>).

id	rule	files
`bot-architecture`	The Discord bot is a third consumer of backend modules, static lookups and page logic that the collector and the page generators own, so a change made for them must keep the bot importing, querying and rendering	`discord_bot/`, `Dockerfile.bot`, `backend_scripts/databaseConnector.py`, `backend_scripts/commonUtils.py`, `backend_scripts/chartData.py`, `backend_scripts/tierMath.py`, `backend_scripts/season_gate.py`, `backend_scripts/computeBuildPhase.py`, `backend_scripts/image_generation/`, `assets/js/analyzer.js`
`bot-db-grants`	The bot and CI connect to production MySQL with their own users, and database.sql is not applied to the server automatically, so a table the bot touches is created and granted by hand	`discord_bot/usage_stats.py`, `discord_bot/cogs/news.py`, `backend_scripts/broadcastDiscordNews.py`
`ops-discord-channels`	Which Discord webhook carries which ops output (the self-editing collector status and bot usage embeds vs. alerts, entrypoint pings and watchtower), and what the embeds need from docker-compose.yml to stay single and visible	`backend_scripts/discordHandler.py`, `discord_bot/usage_stats.py`, `entrypoint.sh`, `entrypoint_bot.sh`, `docker-compose.yml`
