Plan 05: Blind Structure + Chip Sets + Templates Summary

Full CRUD for all building blocks (chip sets, blind structures, payouts, buy-ins) with 4 built-in tournament templates, structure wizard algorithm, and REST API endpoints

Performance

• Duration: 10 min
• Started: 2026-03-01T02:48:52Z
• Completed: 2026-03-01T02:58:52Z
• Tasks: 2
• Files modified: 12

Accomplishments

• Complete CRUD services for all 5 building block types with validation, duplication, and builtin protection
• Structure wizard generates blind structures from high-level inputs (player count, chips, duration, denominations) using geometric progression with denomination snapping
• 4 built-in tournament templates (Turbo, Standard, Deep Stack, WSOP-style) with matching blind structures, buy-in configs, and shared payout structure
• Full REST API with admin-gated mutations and floor-accessible reads
• Comprehensive test suites for wizard (6 tests) and templates (7 tests), all passing

Task Commits

Each task was committed atomically:

1. Task E1: Building block CRUD and API routes - 99545bd (feat)
2. Task E2: Built-in templates, seed data, wizard tests, template tests - 7dbb4ca (feat)

Files Created/Modified

• internal/template/chipset.go - ChipSet CRUD service with denomination management
• internal/template/payout.go - PayoutStructure CRUD with bracket/tier nesting and 100% sum validation
• internal/template/buyin.go - BuyinConfig CRUD with rake split validation
• internal/template/tournament.go - TournamentTemplate CRUD with FK validation, expanded view, SaveAsTemplate
• internal/blind/structure.go - BlindStructure CRUD with level validation (contiguous positions, SB < BB)
• internal/blind/wizard.go - Structure wizard: geometric progression, denomination snapping, break insertion, chip-up markers
• internal/blind/templates.go - Built-in level definitions (Turbo, Standard, Deep Stack, WSOP-style)
• internal/server/routes/templates.go - REST API handlers for all building blocks and templates
• internal/store/migrations/005_builtin_templates.sql - Seed data for 4 blind structures, 1 payout structure, 4 buy-in configs, 4 tournament templates
• internal/blind/wizard_test.go - Wizard tests: standard, player counts, denomination alignment, short/long, invalid inputs
• internal/template/tournament_test.go - Template tests: create, invalid FK, expanded, save-as, duplicate, delete-builtin, list
• internal/server/server.go - Wired template routes into protected API group

Decisions Made

• Seed data uses INSERT OR IGNORE with explicit integer IDs for idempotent migration re-runs
• Wizard generates preview-only levels (not auto-saved) so the TD can review and adjust before saving
• WSOP-style blind structure uses BB ante (separate field from standard ante) starting at level 4
• Payout bracket validation enforces contiguous entry count ranges with no gaps
• All built-in entities use is_builtin=1 flag -- cannot be deleted but can be duplicated

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• Pre-existing test failure in cmd/leaf/main_test.go (missing clockRegistry parameter from Plan D) -- out of scope, not caused by this plan

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• All building blocks have full CRUD with API endpoints -- ready for frontend template management UI
• Tournament templates compose building blocks by reference -- ready for tournament creation flow
• Structure wizard is functional -- ready for frontend wizard UI
• Built-in templates exist on first boot -- ready for template-first tournament creation

Self-Check: PASSED

All 11 created files verified on disk. Both task commits (99545bd, 7dbb4ca) found in git log.
