+# Phase 2 Migration Plan Update Summary
+
+**Date:** 2025-10-27
+**Branch:** feature/sqlx-equality-tests
+**Commit:** a252cff
+
+---
+
+## Changes Made
+
+### 1. ✅ Verified Actual Assertion Counts
+
+**Command Run:**
+```bash
+./tools/count-assertions.sh
+```
+
+**Results:**
+- **Actual Total:** 513 assertions (across 38 SQL files)
+- **Plan Stated:** 558 assertions ❌
+- **Discrepancy:** 45 assertions difference
+
+**Root Cause:** Plan was based on outdated counts.
+
+---
+
+### 2. ✅ Verified Current Migration Status
+
+**Git Commits Checked:**
+```
+b213d55 - test(sqlx): add equality operator and eq() function tests
+28a0eb9 - test(sqlx): add comprehensive JSONB operator tests
+```
+
+**Current Rust Test Files:**
+- `tests/sqlx/tests/equality_tests.rs` - 15 tests
+- `tests/sqlx/tests/jsonb_tests.rs` - 19 tests
+- `tests/sqlx/tests/test_helpers_test.rs` - 1 test
+- **Total:** 35 Rust tests
+
+**SQL Assertions Migrated:**
+- `src/operators/=_test.sql` → 28 assertions ✅
+- `src/jsonb/functions_test.sql` → 28 assertions ✅
+- **Total Migrated:** 56 assertions (not 40 as plan stated)
+
+**Current Coverage:** 56/513 = **10.9%** (was incorrectly stated as 7.2%)
+
+---
+
+### 3. ✅ Updated Plan with Correct Numbers
+
+**All Coverage Percentages Recalculated:**
+
+| Task | Assertions | Old % | New % | Status |
+|------|------------|-------|-------|--------|
+| Current | 56 | 7.2% | 10.9% | ✅ Fixed |
+| Task 1 (inequality) | 14 | 9.7% | 13.6% | ✅ Fixed |
+| Task 2 (< operator) | 13 | 12.0% | 16.2% | ✅ Fixed |
+| Task 3 (> operator) | 13 | 14.3% | 18.7% | ✅ Fixed |
+| Task 4 (<= operator) | 12 | 16.5% | 21.1% | ✅ Fixed |
+| Task 5 (>= operator) | 24 | 20.8% | 25.7% | ✅ Fixed |
+| Task 6 (ORDER BY) | 20 | 24.4% | 29.6% | ✅ Fixed |
+| ... | ... | ... | ... | ... |
+| **Final** | **513** | **558** | **513** | ✅ Fixed |
+
+**Remaining Work:** 457 assertions (513 - 56 = 457)
+
+---
+
+### 4. ✅ Split Task 15 into Sub-Tasks
+
+**Original Task 15:** 234 assertions in one monolithic task ❌
+
+**New Structure:** 8 incremental sub-tasks ✅
+
+| Sub-Task | Assertions | Focus | Coverage After |
+|----------|------------|-------|----------------|
+| 15.1 | 41 | encryptindex functions | 320/513 (62.4%) |
+| 15.2 | 41 | operator class tests | 361/513 (70.4%) |
+| 15.3 | 63 | operator compare tests | 424/513 (82.7%) |
+| 15.4 | 45 | index compare functions | 469/513 (91.4%) |
+| 15.5 | 8 | ORE functions | 477/513 (93.0%) |
+| 15.6 | 18 | STE vector tests | 495/513 (96.5%) |
+| 15.7 | 2 | Bloom filter tests | 497/513 (96.9%) |
+| 15.8 | 5 | HMAC + version tests | 502/513 (97.9%) |
+| 15.9 | 0 | ORE CLLW VAR (empty) | - |
+
+**Benefits:**
+- ✅ Incremental progress tracking
+- ✅ Smaller, reviewable commits
+- ✅ Easier to pause/resume
+- ✅ Better error isolation
+
+---
+
+### 5. ✅ Added Recommended Improvements
+
+#### 5a. Index Type Constants Module
+
+**File Created:** `tests/sqlx/src/index_types.rs`
+
+```rust
+pub const HMAC: &str = "hm";
+pub const BLAKE3: &str = "b3";
+pub const ORE64: &str = "ore64";
+pub const ORE_CLLW_U64_8: &str = "ore_cllw_u64_8";
+pub const ORE_CLLW_VAR_8: &str = "ore_cllw_var_8";
+pub const ORE_BLOCK_U64_8_256: &str = "ore_block_u64_8_256";
+```
+
+**Exported in lib.rs:**
+```rust
+pub mod index_types;
+pub use index_types as IndexTypes;
+```
+
+**Benefit:** Prevents typos in index type strings across 30+ test files.
+
+---
+
+#### 5b. Fixture Schema Documentation
+
+**File Created:** `tests/sqlx/fixtures/FIXTURE_SCHEMA.md`
+
+**Contents:**
+- Fixture dependency graph
+- Schema documentation for each fixture:
+  - `encrypted_json.sql` (3 records, HMAC index)
+  - `array_data.sql` (array test data)
+  - `ore_data.sql` (99 records, ORE64 index)
+- Usage notes for each fixture
+- Validation test examples
+- Troubleshooting guide
+
+**Benefit:** Clear fixture contracts prevent test failures from fixture changes.
+
+---
+
+#### 5c. Updated Test Infrastructure Documentation
+
+**Added to Plan Header:**
+```markdown
+**Test Infrastructure:**
+- 📦 Index type constants: `tests/sqlx/src/index_types.rs`
+- 📋 Fixture documentation: `tests/sqlx/fixtures/FIXTURE_SCHEMA.md`
+- ✅ Assertion helpers: `tests/sqlx/src/assertions.rs`
+- 🎯 Selector constants: `tests/sqlx/src/selectors.rs`
+```
+
+**Benefit:** Clear reference for developers implementing tests.
+
+---
+
+### 6. ✅ Updated Success Criteria
+
+**Old Success Criteria:**
+- All 558 SQL assertions migrated ❌
+
+**New Success Criteria:**
+- ✅ All 513 SQL assertions migrated to Rust/SQLx
+- ✅ Coverage tracking shows 513/513 (100%)
+- ✅ Test inventory shows all 37 test files complete (+ 1 empty file)
+- ✅ Index type constants in use across all tests
+- ✅ Fixture documentation complete
+
+---
+
+### 7. ✅ Updated Priority Matrix
+
+**Old Priority Matrix:** Incorrect assertion counts per priority
+
+**New Priority Matrix:**
+1. **P0 - Critical Operators (82 assertions):** < > <= >= <>
+2. **P1 - Infrastructure (123 assertions):** Config, operator class, encryptindex
+3. **P2 - JSONB Operators (17 assertions):** -> ->>
+4. **P3 - ORE Variants (59 assertions):** ORE equality/comparison variants
+5. **P4 - Containment (8 assertions):** @> <@
+6. **P5 - Advanced Features (36 assertions):** ORDER BY, LIKE, aggregates, constraints
+7. **P6 - Infrastructure Tests (132 assertions):** Compare tests, STE vec, bloom filter
+
+**Total P0-P6:** 457 assertions (matches remaining work: 513 - 56 = 457) ✅
+
+---
+
+## Files Modified
+
+### Plan File
+- `docs/plans/2025-10-27-complete-sqlx-test-migration-phase-2.md`
+  - Updated all assertion counts (558 → 513)
+  - Updated migrated count (40 → 56)
+  - Recalculated all coverage percentages
+  - Split Task 15 into 8 sub-tasks
+  - Added test infrastructure section
+  - Updated success criteria
+
+### New Infrastructure Files
+- `tests/sqlx/src/index_types.rs` - Index type constants
+- `tests/sqlx/fixtures/FIXTURE_SCHEMA.md` - Fixture documentation
+- `tests/sqlx/src/lib.rs` - Export IndexTypes module
+
+### Documentation Files
+- `docs/assertion-counts.md` - Regenerated with latest counts
+- `docs/PLAN_UPDATE_SUMMARY.md` - This file
+
+---
+
+## Verification Steps Completed
+
+### ✅ Step 1: Run assertion count script
+```bash
+./tools/count-assertions.sh
+# Result: 513 total assertions (38 files)
+```
+
+### ✅ Step 2: Verify migrated tests
+```bash
+git log --oneline --grep="test(sqlx)"
+# Found: b213d55 (equality), 28a0eb9 (JSONB)
+
+ls tests/sqlx/tests/*.rs
+# Found: equality_tests.rs (15 tests)
+#        jsonb_tests.rs (19 tests)
+#        test_helpers_test.rs (1 test)
+```
+
+### ✅ Step 3: Check Rust test count
+```bash
+grep -c "#\[sqlx::test" tests/sqlx/tests/*.rs
+# equality_tests.rs: 15
+# jsonb_tests.rs: 19
+# test_helpers_test.rs: 1
+# Total: 35 tests
+```
+
+### ✅ Step 4: Create infrastructure improvements
+- Created `index_types.rs` with constants
+- Created `FIXTURE_SCHEMA.md` documentation
+- Updated `lib.rs` to export IndexTypes
+
+### ✅ Step 5: Update plan with corrections
+- All coverage percentages recalculated
+- Task 15 split into 8 sub-tasks
+- Test infrastructure documented
+- Success criteria updated
+
+### ✅ Step 6: Commit changes
+```bash
+git add -A
+git commit -m "docs: update Phase 2 migration plan with corrections and improvements"
+# Commit: a252cff
+```
+
+---
+
+## Next Steps for Execution
+
+The plan is now ready for execution. Recommended approach:
+
+1. **Review Updated Plan**
+   - Read `docs/plans/2025-10-27-complete-sqlx-test-migration-phase-2.md`
+   - Verify understanding of corrected numbers
+   - Review fixture documentation in `tests/sqlx/fixtures/FIXTURE_SCHEMA.md`
+
+2. **Use Index Constants**
+   - Import `use eql_tests::IndexTypes;` in test files
+   - Use `IndexTypes::HMAC`, `IndexTypes::BLAKE3`, etc.
+   - Prevents typo errors
+
+3. **Follow Task Order**
+   - Phase 1: Tasks 1-6 (comparison operators, ORDER BY)
+   - Phase 2: Task 7 (JSONB path operators)
+   - Phase 3: Tasks 8-9 (ORE variants)
+   - Phase 4: Task 10 (containment)
+   - Phase 5: Tasks 11-13 (LIKE, aggregates, constraints)
+   - Phase 6: Tasks 14-15 (config, infrastructure)
+
+4. **Track Progress**
+   - Use `./tools/check-test-coverage.sh` after each commit
+   - Update `docs/test-inventory.md` with `./tools/generate-test-inventory.sh`
+   - Verify coverage percentages match plan
+
