 ## Tech Stack
 
-- **Runtime:** Node.js 18 (Alpine in Docker)
+- **Runtime:** Node.js 22 (slim/Debian-based in Docker)
+- **Hosting:** Gitea (`gitea.shcizo.se/shcizo/pdga-rating`) — use `tea` CLI for issues/PRs, not `gh`
 - **Server:** Express with EJS templates
 - **Database:** SQLite3 (file: `ratings.db`, Docker: `/app/data/ratings.db`)
 - **Frontend:** HTMX + vanilla JS (in `public/js/`)
 - **Scraping:** Puppeteer (with stealth plugin) + direct HTTP
 - **Logging:** Pino (JSON in production, pino-pretty in dev)
-- **CI/CD:** Release Please + Docker build/push to GHCR
+- **CI/CD:** Gitea Actions (tag-triggered build + push + deploy via `.gitea/workflows/deploy.yml`)
 
 ## Project Structure
 
@@ -38,15 +39,25 @@ public/
 - `LOG_LEVEL=debug npm start` — Enable debug logging
 - `docker compose up` — Run via Docker
 
+**No test framework or lint setup** — `package.json` has only `start` and `dev` scripts. If adding either, document it here.
+
 ## Conventions
 
 - **Logging:** Use `require('./logger')` (or relative path). Never use `console.log/error` in backend code. Use appropriate Pino levels: `debug` for verbose/diagnostic data, `info` for operational status, `warn` for retries/degraded state, `error` for failures, `fatal` for startup crashes.
 - **Frontend JS:** `console.error` is fine in `public/js/` — runs in browser, no Pino.
-- **Commits:** Conventional commits (`feat:`, `fix:`, `refactor:`, `chore:`) — drives release-please.
+- **Commits:** Conventional commits (`feat:`, `fix:`, `refactor:`, `chore:`, `ci:`).
+- **Releases:** Automated via `.gitea/workflows/release.yml` on push to `main`. Workflow scans conventional commits sedan senaste `v*`-taggen och bumpar strikt semver: `feat:` → minor, `fix:` → patch, `!:`/`BREAKING CHANGE` → major. Andra prefix (`chore:`, `docs:`, `ci:`, `refactor:`, `style:`, `test:`) bumpar inte. Workflow:n uppdaterar `package.json` + `package-lock.json`, committar som `<version>`, taggar `v<version>` och pushar. Tag-pushen triggar `.gitea/workflows/deploy.yml` som (1) bygger + pushar image till `gitea.shcizo.se/shcizo/pdga-rating:<tag>` + `:latest`, sen (2) anropar `package-updater-action` mot `updater.shcizo.se/update`. Required secrets: `PACKAGES_TOKEN` (PAT med `write:package` + repo-push-scope — används av både release.yml för att pusha main/tag och deploy.yml för registry-auth; auto-injicerade `GITEA_TOKEN` triggar inte cross-workflows och saknar effective registry-access) och `UPDATER_API_KEY` (för updater-endpointen). Action-repot `shcizo/package-updater-action` refereras via full Gitea-URL (`https://gitea.shcizo.se/...`) eftersom `uses:` defaultar till GitHub. **Manuell tag** är fortfarande möjlig om release-workflow:n skippas eller behöver kringgås — pusha bara `v<version>`-tag direkt.
 - **Scraping:** Two strategies per entity: direct HTTP (fast, preferred) with Puppeteer fallback (stealth plugin for anti-bot). Rate limiting must be respected.
 - **Database:** Migrations run automatically on startup in `db.js`. Schema changes go there.
 - **Templates:** EJS with shared layout in `views/partials/`. Pages use HTMX for dynamic content loading.
 
+## PDGA Domain Notes
+
+- **Rating publication cycle:** PDGA officially recalculates ratings on the **second Tuesday of each month**. `getNextPDGAUpdateDate()` in `src/services/rating-calculator.js` computes this — round filtering uses it as cutoff.
+- **Predicted rating algorithm:** `calculatePredictedRating(roundRatings)` replicates PDGA's formula — 12-mo window (expands to 24 if <8 rounds), outlier removal at ≥7 rounds (2.5σ + 100pt threshold), double-weighting of recent 25% at ≥9 rounds. Returns `{rating, stdDev, debugLog}`.
+- **Rate limits:** `POST /api/refresh-round-history/:pdgaNumber` enforces a 24h cooldown per player (`src/routes/players.js`). Don't bypass — PDGA's site rate-limits aggressively.
+- **Round history refresh** uses Puppeteer (stealth plugin), other scraping prefers direct HTTP. Predicted rating is recomputed and stored on each refresh.
