NRL TipBot

Codex-managed NRL tipping dashboard with weekly verified round notes, charity bet tracking, and static GitHub Pages deployment.

What It Does

NRL TipBot is a static weekly command board for:

• NRL round previews, wraps, and tip confidence
• Official-source team news and late-mail notes
• Charity betting discipline and ledger tracking
• A compact live-round tracker for results and validation notes
• GitHub Pages publishing from a generated index.html

The app started as a single prototype file and now keeps content, live round data, and presentation separated so weekly updates are easier to review.

Current Snapshot

• Round: Round 21, 2026
• Mode: market-aware top-two chase
• Tipping comp handle: Prince_of_Penrith
• Ladder target: top 2 before finals; latest exact gap needs a fresh comp screenshot after Round 20
• Last card: Round 20 validated 8 from 8
• Tip card: Panthers, Roosters, Storm, Raiders, Warriors, Broncos, Titans, Sharks
• Charity bet status: no Round 21 bet locked
• Charity ledger: 3-2, $31.50 invested, $32.03 returned, +$0.53 profit
• Validation rule: do not move the charity ledger without recorded TAB odds, stake, result, and user confirmation

Round 21 tips:

1. Panthers over Eels - heavy favourite protect pick
2. Roosters over Knights - market match with Tedesco back
3. Storm over Rabbitohs - controlled split against the market
4. Raiders over Wests Tigers - heavy favourite protect pick
5. Warriors over Bulldogs - favourite protect pick
6. Broncos over Cowboys - narrow favourite match
7. Titans over Dragons - tiny-market split
8. Sharks over Sea Eagles - favourite protect pick

Round 21 notes:

• The board now prioritises getting Prince_of_Penrith to 2nd before finals without reckless full-card chasing.
• The last known 5-point gap came from the supplied Round 19 screenshot; a fresh ladder screenshot is needed after Round 20.
• Use one or two controlled differentials per full round after modelling likely leader tips.
• Use betting-market favourites each week as a proxy for safe leader picks; NourilM and Kristy W13 are likely to protect position by backing favourites.
• Classify every game as favourite match, controlled split, or avoid before lockout.
• Sportsbet favourites for Round 21 are Panthers, Roosters, Rabbitohs, Raiders, Warriors, Broncos, Dragons and Sharks.
• TipBot matches six favourites and splits on Storm over Rabbitohs plus Titans over Dragons.
• No Round 21 charity bet is locked, so the Mark Hughes Foundation ledger stays unchanged regardless of tipping-comp outcomes.

Round 20 notes carried forward:

• Round 20 card was validated as 8 from 8 from official NRL result lines.
• Correct tips: Broncos, Sharks, Roosters, Raiders, Warriors, Bulldogs, Titans and Dolphins.
• No Round 20 charity bet was locked, so the Mark Hughes Foundation ledger stayed unchanged.

Round 19 notes carried forward:

• Round 19 card finished as 3 correct and 4 missed after a user-reported Storm win over the Titans.
• Storm v Titans exact score still needs official confirmation before publishing the final score line, but the tip direction is treated as correct.

Round 18 notes carried forward:

• No Round 18 charity bet was locked, so the Mark Hughes Foundation ledger stayed unchanged.
• Round 18 should not be published as a final tip-count wrap without clean result cross-checking.

Round 12 remains validated as a 5 from 5 result and must not be changed without re-checking official NRL scores.

Update Workflow

1. Edit data/briefing.json for the durable board content.

2. Edit data/live-round.json for current round status, sources, alerts, and results.

3. Validate the JSON:

   node -e 'JSON.parse(require("fs").readFileSync("data/briefing.json","utf8")); JSON.parse(require("fs").readFileSync("data/live-round.json","utf8")); console.log("json ok")'

4. Build the static output:

   npm run build

5. Sync the generated page to the GitHub Pages entry file:

   cp dist/index.html index.html

6. Check the result locally, then commit and push main.

Development Commands

npm run build     # Generate dist/index.html and dist/README.md
npm run sync      # Alias for the same generator
npm run snapshot  # Alias for the same generator

Optional local preview:

python3 -m http.server 4173

Then open http://127.0.0.1:4173/index.html.

Deployment

GitHub Pages serves the root index.html, not dist/index.html.

Always run the build and copy dist/index.html to index.html before pushing. A successful push to main should trigger the Pages build for:

Data Discipline

• Treat NRL tips and charity bets as separate records.
• Treat market prices as tipping-comp intelligence first, not as permission to place a bet.
• Do not retrospectively count an unplaced lean as a charity bet.
• Keep the Mark Hughes Foundation ledger factual and conservative.
• Re-check official NRL sources before publishing a round preview, wrap, or result correction.
• Keep HANDOVER.md current before risky changes, deploys, or long context-heavy sessions.
