+# TASK-157 — Fix crsql_rows_impacted() returning empty string instead of integer
+
+## Goal
+Fix `crsql_rows_impacted()` to return proper integer values. Currently returns empty string, breaking 9 rows_impacted parity tests.
+
+## Status
+- State: triage
+- Priority: high (blocking parity tests)
+
+## Context
+Discovered during build fix session (2025-12-21). After fixing compilation errors from TASK-149, the rows_impacted tests fail with:
+
+```
+Test: SingleInsertSingleTx
+  FAIL: Expected 1, got: 
+Test: ManyInsertsInATx
+  FAIL: Expected 3, got: 
+Test: CountResetsOnCommit
+  FAIL: Expected 0 after commit, got: 
+Test: UpdateThatDoesNotChangeAnything
+  FAIL: Expected 0 for no-op, got: 
+Test: LowerColVersionLoses
+  FAIL: Expected 0, got: 
+Test: ValueWin
+  FAIL: Expected 1, got: 
+Test: ClockWin
+  FAIL: Expected 1, got: 
+Test: Delete
+  FAIL: Expected 1, got: 
+Test: DeleteThatDoesNotChangeAnything
+  FAIL: Expected 0, got: 
+```
+
+Note: The "got:" values are empty strings, not integers.
+
+## Possible Root Causes
+1. The `crsql_rows_impacted()` function may not be properly incrementing the counter
+2. The counter may be getting reset unexpectedly
+3. The function may be returning NULL/empty instead of the counter value
+4. Changes to `changes_vtab.zig` may have broken the `rows_impacted.incrementRowsImpacted()` calls
+
+## Files to Investigate
+- `zig/src/rows_impacted.zig` - counter implementation
+- `zig/src/changes_vtab.zig` - where `incrementRowsImpacted()` is called
+- `zig/harness/test-parity.sh` - test harness (verify test expectations)
+
+## Acceptance Criteria
+1. All 9 rows_impacted tests pass:
+   - SingleInsertSingleTx: returns 1
+   - ManyInsertsInATx: returns 3
+   - CountResetsOnCommit: returns 0 after commit
+   - UpdateThatDoesNotChangeAnything: returns 0
+   - LowerColVersionLoses: returns 0
+   - ValueWin: returns 1
+   - ClockWin: returns 1
+   - Delete: returns 1
+   - DeleteThatDoesNotChangeAnything: returns 0
+
+2. `crsql_rows_impacted()` returns integer, not empty string

+# TASK-158 — Add proper caching for zeroClockOnResurrect
+
+## Goal
+Implement proper statement caching for `zeroClockOnResurrectCached()` instead of falling back to uncached version.
+
+## Status
+- State: triage
+- Priority: low (optimization, not blocking)
+
+## Context
+During the build fix session (2025-12-21), `zeroClockOnResurrectCached()` was added as a stub that falls back to the uncached `zeroClockOnResurrect()`. This works but loses the performance benefit of statement caching.
+
+Current implementation:
+```zig
+pub fn zeroClockOnResurrectCached(
+    stmts: *TableMergeStmts,
+    pk: i64,
+) MergeError!void {
+    // Format SQL on first use - need to add sql buffer and stmt handle for this
+    // For now, fall back to uncached version
+    return zeroClockOnResurrect(stmts.db, stmts.table_name, pk);
+}
+```
+
+## Files to Modify
+- `zig/src/merge_insert.zig`:
+  - Add `sql_zero_clock_resurrect: [512]u8` buffer to `TableMergeStmts`
+  - Add `zero_clock_resurrect_stmt: ?*api.sqlite3_stmt` handle to `TableMergeStmts`
+  - Update `deinit()` to finalize the statement
+  - Implement proper caching in `zeroClockOnResurrectCached()`
+
+## Acceptance Criteria
+1. `zeroClockOnResurrectCached()` uses cached prepared statement
+2. SQL is formatted once on first call, reused thereafter
+3. No performance regression (should be faster than current fallback)
+4. Statement properly finalized in `deinit()`

-## ⚠️ CRITICAL: Build Broken
-
-The codebase does not compile. `make -C zig test-parity` fails with 4 errors:
-
-1. `src/changes_vtab.zig:1707` — unused local constant `base_rowid`
-2. `src/changes_vtab.zig:1539` — `TableMergeStmts.init()` returns struct, not error union (bad `catch`)
-3. `src/changes_vtab.zig:1721` — `?[*]const u8` passed where `[*]const u8` expected (missing unwrap)
-4. `src/merge_insert.zig:89` — `api.clear_bindings` doesn't exist (no such function)
-
-**Root cause**: TASK-149 was marked "done" but left incomplete code. Must fix compilation errors before any testing.
-
 ## Now (next parallel assignments)
 
-**BLOCKED** — Cannot assign work until build is fixed.
-
-Priority order after build fix:
-1. Fix compilation errors (unassigned — needs new task or reopen TASK-149)
-2. Continue TASK-147 decomposition (TASK-150, 151, 152 in triage)
-3. Run parity tests to verify state
+Priority order:
+1. Continue TASK-147 decomposition (TASK-150, 151, 152 in triage)
+2. Run full parity tests to assess state
+3. Fix remaining parity test failures
