# Phase 2: Constraint Validation Verification Report
**Phase Goal:** The system prevents invalid positions and enforces item-specific rules.
**Verified:** 2026-01-18T21:30:00Z
**Status:** passed
**Re-verification:** No - initial verification
## Goal Achievement
### Observable Truths
| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Games cannot be moved (CONS-01) | VERIFIED | `ItineraryConstraints.isValidPosition()` returns `false` for `.game` case (line 28-30). Tests `game_cannotBeMoved` and `success_gameNotDraggable` verify. |
| 2 | Travel segments constrained to valid day range (CONS-02) | VERIFIED | `validDayRange()` method (line 47-60) calculates range based on departure/arrival games. Tests `travel_validDayRange_simpleCase`, `travel_cannotGoOutsideValidDayRange` verify. |
| 3 | Travel must be after from-city games, before to-city games on same day (CONS-03) | VERIFIED | `isValidTravelPosition()` method (line 85-121) enforces sortOrder constraints. 5 tests cover this requirement. |
| 4 | Custom items have no constraints (CONS-04) | VERIFIED | `isValidPosition()` returns `true` for `.custom` case (line 40-43). Tests `custom_canGoOnAnyDay`, `custom_canGoBeforeOrAfterGames`, `success_customNotePlacedAnywhere` verify. |
| 5 | Tests use Swift Testing framework (@Test, @Suite) | VERIFIED | File uses `import Testing`, `@Suite("ItineraryConstraints")`, and `@Test` decorators. 22 tests total. |
| 6 | API documentation exists for Phase 4 integration | VERIFIED | `CONSTRAINT-API.md` documents `isValidPosition()`, `validDayRange()`, `barrierGames()` with usage examples. |
**Score:** 6/6 truths verified
### Required Artifacts
| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `SportsTimeTests/Domain/ItineraryConstraintsTests.swift` | Migrated constraint tests with @Suite | EXISTS + SUBSTANTIVE + WIRED | 398 lines, 22 @Test functions, uses Swift Testing, imports @testable SportsTime |
| `SportsTime/Core/Models/Domain/ItineraryConstraints.swift` | Implementation with isValidPosition | EXISTS + SUBSTANTIVE | 134 lines, 3 public methods, no stub patterns |
| `.planning/phases/02-constraint-validation/CONSTRAINT-API.md` | API documentation for Phase 4 | EXISTS + SUBSTANTIVE | 165 lines, documents all 3 public methods with examples |
### Key Link Verification
| From | To | Via | Status | Details |
|------|-----|-----|--------|---------|
| `ItineraryConstraintsTests.swift` | `ItineraryConstraints.swift` | `@testable import SportsTime` | WIRED | Line 11: `@testable import SportsTime` |
| `CONSTRAINT-API.md` | `ItineraryConstraints.swift` | documents public API | WIRED | Documents `isValidPosition`, `validDayRange`, `barrierGames` methods |
### Requirements Coverage
| Requirement | Status | Test Evidence |
|-------------|--------|---------------|
| CONS-01: Games cannot be moved | SATISFIED | `game_cannotBeMoved()`, `success_gameNotDraggable()` |
| CONS-02: Travel segments constrained to valid day range | SATISFIED | `travel_validDayRange_simpleCase()`, `travel_cannotGoOutsideValidDayRange()`, `edge_travelNoGamesInEitherCity_hasFullRange()` |
| CONS-03: Travel segments must be after from-city games, before to-city games on same day | SATISFIED | `travel_mustBeAfterDepartureGames()`, `travel_mustBeBeforeArrivalGames()`, `travel_canBeAnywhereOnRestDays()`, `travel_mustBeAfterAllDepartureGamesOnSameDay()`, `travel_mustBeBeforeAllArrivalGamesOnSameDay()` |
| CONS-04: Custom items have no constraints | SATISFIED | `custom_canGoOnAnyDay()`, `custom_canGoBeforeOrAfterGames()`, `success_customNotePlacedAnywhere()` |
### Success Criteria from Roadmap
| Criteria | Status | Evidence |
|----------|--------|----------|
| Attempting to drag a game row shows no drag interaction | VERIFIED | `isValidPosition()` returns `false` for all game positions. Test `success_gameNotDraggable()` verifies. |
| Travel segment between Chicago and Boston cannot be placed on Day 1 if Chicago games extend through Day 2 | VERIFIED | `validDayRange()` returns minDay based on last departure game. Test `travel_cannotGoOutsideValidDayRange()` verifies. |
| Custom note item can be placed before, between, or after games on any day | VERIFIED | Test `success_customNotePlacedAnywhere()` explicitly verifies all positions. |
| Invalid position attempt returns rejection (constraint checker returns false) | VERIFIED | Test `success_invalidPositionReturnsRejection()` verifies false return. |
### Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| None | - | - | - | No anti-patterns detected |
### Human Verification Required
None - all success criteria are verifiable through automated tests.
### Test Execution Summary
All 22 constraint tests pass:
- 2 tests for CONS-01 (games immutable)
- 3 tests for CONS-02 (travel day range)
- 5 tests for CONS-03 (travel sortOrder)
- 2 tests for CONS-04 (custom flexibility)
- 8 tests for edge cases (boundaries, impossible constraints)
- 3 tests for success criteria verification
