The old validation expected exactly 2 mint instructions (developer + admin), but with emission splits, there can be N recipients (70/30 split = 2 recipients + 1 admin = 3 mints). Changes: - Dynamic recipient count validation (N splits + 1 admin) - Build expected recipients map with token accounts and amounts - Validate each mint instruction against expected recipients - Ensure all expected recipients receive correct amounts - Reject unauthorized recipients or incorrect amounts Security improvements: - More precise validation (exact amounts per recipient) - No unauthorized recipients allowed - No amount manipulation possible - Works with any number of split recipients (1, 2, 3+) - Maintains backwards compatibility (1 recipient = creator only) Testing: - Validates 70/30 split: Creator gets 630, Team gets 270, Admin gets 100 - Validates no splits: Creator gets 900, Admin gets 100 - Rejects any unauthorized recipients - Rejects incorrect amounts Also added PR_REVIEW_GUIDE.md with comprehensive review instructions and testing scenarios. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- ui/PR_REVIEW_GUIDE.md | 546 ++++++++++++++++++++++++++++++++++++++++++ ui/routes/claims.ts | 140 +++++++---- 2 files changed, 636 insertions(+), 50 deletions(-) create mode 100644 ui/PR_REVIEW_GUIDE.md diff --git a/ui/PR_REVIEW_GUIDE.md b/ui/PR_REVIEW_GUIDE.md new file mode 100644 index 0000000..8a73b8b --- /dev/null +++ b/ui/PR_REVIEW_GUIDE.md @@ -0,0 +1,546 @@ +# PR #3 Review Guide + +## Quick Review Checklist + +### Part 1: High-Level Review (5 minutes) +- [ x] Review PR description on GitHub +- [ x] Check commit messages make sense +- [ x] Verify file changes look reasonable +- [x] Check REFACTORING_VERIFICATION.md + +### Part 2: Refactoring Verification (10 minutes) +- [ x] Verify route URLs unchanged +- [ ] Check code compilation +- [ ] Review new file structure +- [ ] Verify no logic changes + +### Part 3: Emission Splits Feature Review (15 minutes) +- [ ] Review emission split logic +- [ ] Check authorization flow +- [ ] Verify backwards compatibility +- [ ] Review security considerations + +### Part 4: Testing (20 minutes) +- [ ] Test with emission splits +- [ ] Test without emission splits +- [ ] Test unauthorized access +- [ ] Verify split percentages + +--- + +## Part 1: High-Level Review + +### 1.1 View the PR on GitHub +```bash +gh pr view 3 --web +``` + +**What to check:** +- ✅ PR title describes the change +- ✅ Description is comprehensive +- ✅ All commits are logical and well-documented +- ✅ Changes count looks reasonable (2,803 additions, 2,058 deletions) + +### 1.2 Review File Changes +```bash +# View all changed files +gh pr diff 3 --name-only + +# Expected files: +# - api-server.ts (modified) +# - lib/db.ts (modified) +# - lib/claimService.ts (new) +# - lib/presaleService.ts (new) +# - routes/claims.ts (new) +# - routes/presale.ts (new) +# - REFACTORING_VERIFICATION.md (new) +``` + +### 1.3 Read the Verification Document +```bash +cat REFACTORING_VERIFICATION.md +``` + +**What to check:** +- ✅ All route URLs listed and verified +- ✅ Critical logic patterns verified +- ✅ Storage sharing documented +- ✅ Compilation verified + +--- + +## Part 2: Refactoring Verification + +### 2.1 Verify Code Compiles +```bash +# TypeScript compilation should pass +npm run build 2>&1 | grep -i error + +# If no errors shown, compilation passed +``` + +### 2.2 Check Route Mapping +```bash +# Extract all routes from new files +echo "=== CLAIMS ROUTES ===" +grep "^router\.\(get\|post\)(" routes/claims.ts | sed 's/,.*$//' + +echo "" +echo "=== PRESALE ROUTES ===" +grep "^router\.\(get\|post\)(" routes/presale.ts | sed 's/,.*$//' + +echo "" +echo "=== API-SERVER MOUNTS ===" +grep "app.use.*Router" api-server.ts +``` + +**Expected output:** +``` +Claims Routes: +- router.get('/:tokenAddress' → /claims/:tokenAddress +- router.post('/mint' → /claims/mint +- router.post('/confirm' → /claims/confirm + +Presale Routes (mounted at /presale): +- router.get('/:tokenAddress/claims/:wallet' +- router.post('/:tokenAddress/claims/prepare' +- router.post('/:tokenAddress/claims/confirm' +- router.get('/:tokenAddress/stats' +- router.get('/:tokenAddress/bids' +- router.post('/:tokenAddress/bids' +- router.post('/:tokenAddress/launch' +- router.post('/:tokenAddress/launch-confirm' + +API Server Mounts: +- app.use('/claims', claimsRouter);
