Work Summary — 2025-12-22

Overview

Completed P2.1 (iOS schema versioning) and P2.2 (iOS combined edge case tests), designed P2.3 (Android combined tests), fixed parity matrix inaccuracies, and established new baseline tag.

Major Accomplishments

✅ P2.1: iOS Schema Versioning Strategy (Complete)

Implementation:

• Added SCHEMA_VERSION constant (value: 1) to PersistenceController
• Implemented checkSchemaVersion() method that logs version on store load
• Version stored in NSPersistentStore metadata (non-intrusive approach)
• Version mismatches logged as warnings (not blocked) — CoreData auto-migration remains authoritative

Documentation:

• Added schema versioning strategy section to ios/Plugin/README.md
• Clarified: "Schema version is a logical contract, not a forced migration trigger"
• Documented migration contract and Android parity

Files Modified:

• ios/Plugin/DailyNotificationModel.swift (47 lines added)
• ios/Plugin/README.md (87 lines added)

Verification:

• CI passes (./ci/run.sh)
• Version logging verified
• Parity matrix updated

---

✅ P2.2: Combined Edge Case Tests (Complete)

Implementation:

• Added 3 combined resilience test scenarios to DailyNotificationRecoveryTests.swift:
  1. test_combined_dst_boundary_duplicate_delivery_cold_start() — DST + duplicate + cold start
  2. test_combined_rollover_duplicate_delivery_cold_start() — Rollover + duplicate + cold start
  3. test_combined_schema_version_cold_start_recovery() — Schema version + cold start

Test Features:

• All tests labeled with @resilience @combined-scenarios comments
• Tests verify idempotency and correctness under combined stressors
• Tests are deterministic and runnable via xcodebuild on macOS

Files Modified:

• ios/Tests/DailyNotificationRecoveryTests.swift (329 lines added)

Verification:

• Tests runnable via xcodebuild (skipped on Linux CI, expected)
• Test results logged in docs/progress/03-TEST-RUNS.md
• Parity matrix updated with direct test references

📋 P2.3: Android Combined Tests Design (Design Complete)

Design Documents Created:

• docs/progress/P2.3-DESIGN.md — Complete design with scope, invariants, acceptance criteria
• docs/progress/P2.3-IMPLEMENTATION-CHECKLIST.md — Step-by-step implementation guide

Design Highlights:

• 3 work items: P2.3.1 (test infrastructure), P2.3.2 (test helpers), P2.3.3 (combined scenarios)
• CI-compatible approach (JUnit + Robolectric or pure unit tests)
• Mirrors iOS P2.2 intent (not necessarily identical mechanics)
• All 6 invariants documented with P2.3 constraints

Status:

• Design complete and ready for review
• Implementation checklist ready for execution
• Estimated effort: 12-20 hours

---

🔧 Parity Matrix Fixes

Issue Fixed:

• "Invalid data handling" row incorrectly showed iOS as "⚠️ Input validation only"
• Reality: iOS has recovery tests (test_recovery_ignores_invalid_records_and_continues(), test_recovery_handles_null_fields())

Fix Applied:

• Updated to "✅ Recovery tested" for both platforms
• Added direct test references (file path + test names)
• Matches pattern established in P2.2 (direct proof references)

Files Modified:

• docs/progress/04-PARITY-MATRIX.md

📊 Documentation Updates

Progress Documentation:

• docs/progress/00-STATUS.md — Updated baseline tag, phase status, next actions
• docs/progress/01-CHANGELOG-WORK.md — Added P2.1 and P2.2 completion entries
• docs/progress/03-TEST-RUNS.md — Added P2.1 and P2.2 test run entries
• docs/progress/04-PARITY-MATRIX.md — Fixed invalid data handling, added combined tests row
• docs/progress/P2-DESIGN.md — Updated P2.3 scope, marked P2.1/P2.2 complete
• docs/SYSTEM_INVARIANTS.md — Updated baseline tag references

New Documentation:

• docs/progress/P2.3-DESIGN.md — P2.3 design document
• docs/progress/P2.3-IMPLEMENTATION-CHECKLIST.md — P2.3 implementation guide

---

🏷️ Baseline Tag

Tag Created:

• v1.0.11-p2-complete
• Message: "P2.x: iOS schema version observability + combined resilience tests"
• Tag pushed to remote

Tag Represents:

• P2.1: Schema versioning strategy (iOS explicit version tracking)
• P2.2: Combined edge case tests (3 resilience scenarios)
• All invariants preserved
• CI passing
• Ready for P2.3 implementation

---

Statistics

Code Changes:

• iOS implementation: 376 lines added (schema versioning + tests)
• Documentation: ~500 lines added/updated across progress docs

Files Changed:

• Modified: 10 files
• Created: 4 new design/plan documents
• Total: 14 files touched

Test Coverage:

• 3 new combined edge case test scenarios
• All tests labeled and documented
• Direct references in parity matrix

---

Invariants Preserved

✅ All 6 invariants preserved:

1. Packaging invariants (P0) — No forbidden files, exports correct
2. Core module purity (P1.4) — No platform imports in core
3. CI authority (P0) — ./ci/run.sh remains authoritative
4. Export correctness (P0) — All exports match artifacts
5. Documentation structure (P1.5) — Index-first rule followed
6. Baseline tag integrity — Tag represents known-good state

---

Next Steps

Immediate:

1. Review P2.3 design (docs/progress/P2.3-DESIGN.md)
2. Approve test framework choice (Robolectric vs pure unit tests)
3. Begin P2.3.1 — Enable Android test infrastructure

Future:

• P2.3: Android combined edge case tests (implementation)
• P2.4: iOS CI automation (macOS runners) — optional
• P1.5b: Remove iOS/App test harness from published tree — optional
