# Progress Tracker: Capture Source Record Total and Partial Success

## Context
**Objective:** Add a `source_record_count` column to `flow_metrics` and introduce a `partial_success` status to track when dispatched jobs are fewer than the source records (e.g., due to duplicate skipping).

## 🔧 Session 2026-02-27: PR Review Improvements

| Date       | Phase     | Description                                                        | Status       |
|------------|-----------|--------------------------------------------------------------------|--------------|
| 2026-02-27 | Improvement 1  | Guard `!empty($runId)` in `FlowCompletedObserver` — prevents orphan Redis key `flow:{id}:run::source_record_count`. Log::warning added for observability. | ✅ Completed |
| 2026-02-27 | Improvement 1b | Reorder `runId` generation in `ProcessFlow::handle()` — moved before `startFlowMetric()` so all Redis keys share a coherent runId from the start. | ✅ Completed |
| 2026-02-27 | Improvement 1  | Regression test in `FlowPartialSuccessTest` — null runId path keeps `source_record_count=null` and `flow_status='completed'`. | ✅ Completed |
| 2026-02-27 | Improvement 2  | 24h safety TTL on `source_record_count` Redis key: `Redis::setex` in `FlowCounterService::setSourceRecordCount()` + `Redis::expire` after `incrby` in `ProcessFlowPage`. | ✅ Completed |
| 2026-02-27 | Improvement 3  | Atomic Lua decrement in `FlowCounterService::safeDecrementExpectedJobs()` — eliminates race condition where concurrent workers double-decrement. | ✅ Completed |
| 2026-02-27 | Improvement 4  | Wrap `NodeMetric` query in `UsesBufferedQueries` in `FlowCompletedObserver` — prevents PDO unbuffered-query conflicts on MySQL. | ✅ Completed |
| 2026-02-27 | Phase 6   | PHPStan Level 5 — 0 errors on all changed files                    | ✅ Completed |
| 2026-02-27 | Phase 6   | Feature tests passing (3/3, 8 assertions)                          | ✅ Completed |
| 2026-02-27 | Bug Fix   | Lua sentinel: return -1 for no-op vs 0 for decrement-to-zero in `safeDecrementExpectedJobs`. Fixes misleading warning log. | ✅ Completed |
| 2026-02-27 | Bug Fix   | `getFlowMetric` / `getNodeMetric` queries now include `partial_success` in `whereIn` clause. | ✅ Completed |
| 2026-02-27 | Bug Fix   | `Redis::eval` corrected to Predis signature: `Redis::eval($script, 1, $key, $count)`. | ✅ Completed |
| 2026-03-02 | Bug Fix   | Non-atomic `Redis::incrby + expire` in `ProcessFlowPage::processRecordsInBatches` replaced by `FlowCounterService::incrementSourceRecordCount()` using `Redis::pipeline()`. Centralizes key management; satisfies 050-infrastructure atomicity rule. Regression test added in `FlowCounterServiceTest` (2 tests, 12 assertions). PHPStan 0 errors. |  ✅ Completed |
| 2026-03-02 | Bug Fix   | `FlowMetric::isCompleted()` neglects `partial_success` status. Fixed via `in_array` inclusion. Regression test added to `FlowMetricTest`. PHPStan 0 errors. | ✅ Completed |
| 2026-03-02 | Bug Fix   | Migration `down()` method strictly truncates `partial_success` records. Fixed by adding a pre-alter `UPDATE` statement to gracefully map to `completed`. PHPStan 0 errors. | ✅ Completed |
| 2026-03-02 | Bug Fix   | `FlowMetricsService::completeFlowMetric()` unconditionally overwrites source_record_count with default null via legacy callers. Fixed via conditional payload building. Regression test added in `FlowMetricsServiceTest` (2 tests, 6 assertions). PHPStan 0 errors. | ✅ Completed |
| 2026-03-03 | Bug Fix   | `source_record_count` Redis key orphan. Added `"flow:{$flowId}:run:*:source_record_count"` pattern to `CleanupFlowDataService` and removed dead `FlowCounterService::cleanupCounters()` code. Regression test added to `CleanupFlowDataServiceTest`. PHPStan 0 errors. | ✅ Completed |
| 2026-03-03 | Bug Fix   | `source_record_count` missed during run-specific cleanups in `CleanupFlowDataService`. Extracted string keys into centralized `getRunKeyPatterns()` DRY method. Regression test added. PHPStan 0 errors. | ✅ Completed |
| 2026-03-03 | Bug Fix   | High Severity: Subflow wildcard deletion regression. Extracted `getSubflowKeyPatterns()` to segregate operational state from metric runs (DDD). Regression test added. PHPStan 0 errors. | ✅ Completed |
| 2026-03-03 | Bug Fix   | Low Severity: Removed dead `$flowId` parameter from `getSubflowKeyPatterns`. PHPStan 0 errors. | ✅ Completed |
| 2026-03-03 | Bug Fix   | Low Severity: Fixed namespace typo in `FlowPartialSuccessTest` teardown (`$this->tenantDb` -> `$this->context`) preventing SQLite DB leak during local testing. | ✅ Completed |
| 2026-03-03 | Bug Fix   | Medium Severity: Refactored `FlowStatusController` to read run-scoped Redis status and migrated legacy `ProcessFlow` writes to full run-scoped keys format (`flow:{id}:run:{runId}:status`), preventing UI state desync during flow errors. Added `jobs_expected` on fallback failures. PHPStan Level 5 clean. | ✅ Completed |
| 2026-03-03 | Bug Fix   | Low Severity: Fixed missing `source_record_count` column in `FlowMetricTest.php` schema to restore consistency with `FlowMetric` model. | ✅ Completed |
| 2026-03-03 | Bug Fix   | Medium Severity: Added missing run-scoped keys (`started_at`, `start_time`, `error`, `error_at`, `failed_at`, `failure_reason`) to `CleanupFlowDataService::getRunKeyPatterns()` to prevent Redis memory leaks. | ✅ Completed |
| 2026-03-03 | Bug Fix   | Low Severity: Added `jobs_expected` on fallback failures in `ProcessFlow::handleError` and `ProcessFlow::handleFailed` to ensure FlowStatusController can discover these flows. PHPStan 0 errors. | ✅ Completed |
| 2026-03-04 | Bug Fix   | High Severity: Fixed `FlowCompletedObserver::updateFlowMetrics` to read `start_time` from run-scoped Redis key (`flow:id:run:runId:start_time`) before falling back to legacy key. Fixes `total_runtime_ms=0` metric corruption. PHPStan Level 5 clean. | ✅ Completed |
| 2026-03-04 | Refactor  | Medium Severity: Extracted duplicated runId discovery logic from `FlowStatusController` into `FlowCounterService::findLatestRunId()`. Fixes latent `strcmp` type-safety bug; controller now fully decoupled from Redis key format. PHPStan Level 5 clean, 5 tests pass. | ✅ Completed |
| 2026-03-04 | Bug Fix   | Low/Medium Severity: Fixed `CleanupFlowDataServiceTest.php` which was missing mocks for 6 new run-scoped key patterns. The test previously "passed by accident" by swallowing Mockery `NoMatchingExpectationException`. Added strict, explicit mocks for all 11 patterns. Tests pass. | ✅ Completed |
| 2026-03-04 | Bug Fix   | Medium Severity + Security Fix: Removed phantom Redis reads for `started_at`/`completed_at` in `FlowStatusController`. These keys were read but never written (run-scoped migration gap). Timestamps now source from `FlowMetric` DB model (canonical source of truth). `completed_at` added defensively to `CleanupFlowDataService::getRunKeyPatterns()`. Security: moved `user_id`/`ip`/`user_agent` from error response body to `Log::error()`. PHPStan Level 5 clean. 10 tests passed (32 assertions). Commit `7b11aa0c7`. | ✅ Completed |
| 2026-03-05 | Bug Fix   | High Severity: Fixed signature mismatch on `FlowMetricsService::completeFlowMetric()` in `ProcessFlow.php` (empty page condition), converting positional arguments to named arguments (`skippedRecords: $skippedRecords`) to prevent injecting `$skippedRecords` into `$sourceRecordCount`. PHPStan 0 errors. | ✅ Completed |
| 2026-03-05 | Bug Fix   | Low Severity: Fixed duplicate Redis `MGET` call for counter status in `FlowCompletedObserver::updateFlowMetrics()`. The `$counterStatus` payload is now fetched once and reused avoiding unnecessary network round-trips. PHPStan 0 errors. | ✅ Completed |
| 2026-03-05 | Bug Fix   | High Severity: Fixed Redis memory leak by adding missing `jobs_skipped` key to `CleanupFlowDataService::getRunKeyPatterns()` and updating the contract test `CleanupFlowDataServiceTest` to enforce it. | ✅ Completed |
| 2026-03-06 | Bug Fix   | Medium Severity: Fixed Mock fidelity gap in `CleanupFlowDataServiceTest.php` by adding the newly introduced `jobs_skipped` key to the strict Mockery `$runScopedPatterns` expectations. PHPStan 0 errors, tests passing. | ✅ Completed |
| 2026-03-06 | Performance | Low Severity: Optimized memory overhead in `FlowCounterService` hot paths by replacing full `debug_backtrace()` dumps with `DEBUG_BACKTRACE_IGNORE_ARGS` and a strict frame limit. PHPStan 0 errors. | ✅ Completed |
| 2026-03-06 | Bug Fix   | High Severity (Tests): Fixed missing `skipped_records` column in test SQLite schema generation within `FlowPartialSuccessTest.php` and `FlowCompletedObserverTest.php`, preventing silent DB save failures and false test negatives. PHPStan 0 errors. | ✅ Completed |
| 2026-03-06 | Bug Review | False Positive: Analyzed Cursor Bot report "Source record count double-counted for non-paginated flows". Confirmed hallucination; architecture strictly segregates paginated and non-paginated dispatches preventing double `incrementSourceRecordCount` calls. No code changes required. | ✅ Completed |
| 2026-03-06 | Refactor  | Medium Severity: Disambiguated `FlowMetric::isCompleted()` returning true for `partial_success`. Added explicit `isFullySuccessful()` and `isPartiallySuccessful()` methods to allow safer domain assertions without mixing success states. PHPStan 0 errors. | ✅ Completed |
| 2026-03-06 | Bug Fix   | Low Severity (Tests): Fixed missing `source_record_count` column in test SQLite schema generation within `FlowCompletedObserverTest.php`, preventing database exception failures when Redis holds non-zero values test-to-test. | ✅ Completed |
| 2026-03-06 | Bug Fix   | Low Severity: Fixed Redis memory leak in `ProcessFlow` error paths (`handleError`, `gracefullyTerminateFlow`) by replacing indefinite `Redis::set` with `Redis::setex` using a 24-hour TTL (`86400`) for fallback `status`, `error`, `error_at`, `failed_at`, and `failure_reason` keys. | ✅ Completed |
| 2026-03-06 | Bug Fix   | Medium Severity: Expanded Redis memory leak protection to **ALL** run-scoped `Redis::set` calls in `ProcessFlow` and `ProcessFlowPage`. Replaced bare set calls for `started_at`, `jobs_expected`, `jobs_completed` and `completion_event_dispatched` with 24-hour TTL `setex` to act as an absolute safety net against server crashes. | ✅ Completed |
