# Phase 1: Semantic Position Model Verification Report
**Phase Goal:** All movable items have a persistent semantic position that survives data reloads.
**Verified:** 2026-01-18T20:16:17Z
**Status:** passed
**Re-verification:** No — initial verification
## Goal Achievement
### Observable Truths
| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Games sort by schedule time within each day | VERIFIED | `SortOrderProvider.initialSortOrder(forGameTime:)` returns 100 + minutes since midnight (range 100-1540). Tests confirm: midnight=100, noon=820, 7pm=1240, 11:59pm=1539. |
| 2 | Items can be inserted at any position (before, between, after existing items) | VERIFIED | `sortOrderBefore(_:)`, `sortOrderBetween(_:_:)`, `sortOrderAfter(_:)` all implemented. Test `midpointInsertion_50Times_maintainsPrecision` confirms 50+ insertions maintain distinct values. |
| 3 | Items can be assigned to any trip day by date calculation | VERIFIED | `Trip.dayNumber(for:)` and `Trip.date(forDay:)` implemented with correct 1-indexed day calculation. Tests confirm round-trip: dayNumber -> date -> dayNumber. |
| 4 | User can persist an item's position, reload, and find it in the same location | VERIFIED | Tests `itineraryItem_positionSurvivesEncodeDecode` and `localItineraryItem_positionPreservedThroughConversion` confirm day and sortOrder survive JSON encode/decode and SwiftData conversion. |
| 5 | Moving travel segment to different day updates its day property | VERIFIED | Test `travelItem_dayCanBeUpdated` confirms `ItineraryItem.day` is mutable (`var`) and can be updated from 1 to 3 while sortOrder remains unchanged. |
| 6 | Inserting between two items gets sortOrder between their values (e.g., 1.0 and 2.0 -> 1.5) | VERIFIED | Test `midpointInsertion_producesCorrectValue` confirms `SortOrderProvider.sortOrderBetween(1.0, 2.0)` returns 1.5. |
| 7 | Games remain fixed at their schedule-determined positions | VERIFIED | Test `gameItem_sortOrderDerivedFromTime` confirms 7pm game gets sortOrder 1240.0. `ItineraryItem.isGame` property exists. Games are not special-cased for immutability yet (Phase 2 constraint). |
| 8 | Custom items can be placed at any sortOrder value (negative, zero, positive) | VERIFIED | Test `customItem_canBePlacedAtAnyPosition` confirms items at sortOrder -5.0, 500.0, and 2000.0 all persist correctly and sort in correct order. |
**Score:** 8/8 truths verified
### Required Artifacts
| Artifact | Expected | Exists | Substantive | Wired | Status |
|----------|----------|--------|-------------|-------|--------|
| `SportsTime/Core/Models/Domain/SortOrderProvider.swift` | sortOrder calculation utilities | YES | YES (94 lines, 6 methods) | YES (imported by tests, used 22x) | VERIFIED |
| `SportsTime/Core/Models/Domain/Trip.swift` | Day derivation methods | YES | YES (248 lines, dayNumber/date methods at L226-246) | YES (used in tests) | VERIFIED |
| `SportsTime/Core/Models/Domain/ItineraryItem.swift` | Semantic position fields | YES | YES (125 lines, day/sortOrder at L8-9) | YES (used throughout tests) | VERIFIED |
| `SportsTimeTests/Domain/SortOrderProviderTests.swift` | Unit tests for SortOrderProvider (80+ lines) | YES | YES (228 lines, 22 tests) | YES (@testable import SportsTime, 22 SortOrderProvider calls) | VERIFIED |
| `SportsTimeTests/Domain/SemanticPositionPersistenceTests.swift` | Integration tests for persistence (100+ lines) | YES | YES (360 lines, 12 tests) | YES (@testable import SportsTime, uses LocalItineraryItem 5x) | VERIFIED |
| `SportsTime/Core/Models/Local/SavedTrip.swift` (LocalItineraryItem) | SwiftData persistence model | YES | YES (day/sortOrder fields at L110-111, from/toItem conversions) | YES (used in persistence tests) | VERIFIED |
### Key Link Verification
| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| SortOrderProviderTests | SortOrderProvider | Test imports and method calls | WIRED | 22 direct calls to SortOrderProvider methods (initialSortOrder, sortOrderBetween, sortOrderBefore, sortOrderAfter, needsNormalization, normalize) |
| SemanticPositionPersistenceTests | LocalItineraryItem | SwiftData conversion | WIRED | Tests LocalItineraryItem.from() and .toItem for position persistence round-trip |
| SemanticPositionPersistenceTests | Trip | Day derivation methods | WIRED | Tests Trip.dayNumber(for:) and Trip.date(forDay:) |
| LocalItineraryItem | ItineraryItem | from/toItem conversion | WIRED | LocalItineraryItem.from(_:) encodes kind to kindData, preserves day/sortOrder. toItem decodes back. |
### Requirements Coverage
| Requirement | Status | Evidence |
|-------------|--------|----------|
| DATA-01: All movable items have semantic position (day: Int, sortOrder: Double) | SATISFIED | ItineraryItem has `var day: Int` and `var sortOrder: Double` at lines 8-9 |
| DATA-02: Travel segments are positioned items with their own sortOrder | SATISFIED | ItineraryItem.Kind includes `.travel(TravelInfo)` case with same day/sortOrder fields |
| DATA-03: Games are immovable anchors ordered by game time within each day | SATISFIED | `initialSortOrder(forGameTime:)` derives sortOrder from time. Immutability is Phase 2 constraint. |
| DATA-04: Custom items can be placed anywhere within any day | SATISFIED | Test confirms sortOrder -5.0, 500.0, 2000.0 all work on same day |
| DATA-05: Items always belong to exactly one day | SATISFIED | `ItineraryItem.day` is a single `Int` (not optional, not array). Test confirms this. |
| PERS-01: Semantic position survives data reloads from SwiftUI/SwiftData | SATISFIED | Tests confirm encode/decode and LocalItineraryItem conversion preserve day/sortOrder |
| PERS-02: No visual-only state; all positions are persisted semantically | SATISFIED | Test confirms day and sortOrder appear in JSON output (Codable) |
| PERS-03: Midpoint insertion for sortOrder enables unlimited insertions | SATISFIED | Test confirms 50 midpoint insertions maintain distinct values; normalize() rebalances |
### Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| (none) | - | - | - | No anti-patterns found |
No TODO, FIXME, placeholder, or stub patterns found in phase 1 artifacts.
### Human Verification Required
None required. All truths are verifiable programmatically through:
1. File existence checks
2. Method signature verification
3. Test execution (all 34 tests pass)
4. Code structure analysis
### Gaps Summary
No gaps found. Phase 1 goal achieved:
- ItineraryItem model has persistent semantic position (day, sortOrder)
- SortOrderProvider provides utilities for sortOrder calculation
- Trip provides day derivation methods
- Comprehensive test coverage (34 tests) verifies all requirements
- All tests pass
- No stub patterns or incomplete implementations
