Phase 2 Plan 4: Gap Closure Summary

Diagram hash linking during execution ingestion via DiagramRepository lookup, plus Surefire/Failsafe classloader isolation and test stability fixes

Performance

• Duration: 22 min
• Started: 2026-03-11T16:13:57Z
• Completed: 2026-03-11T16:36:49Z
• Tasks: 1
• Files modified: 5

Accomplishments

• diagram_content_hash populated with active RouteGraph SHA-256 hash during batch insert (DIAG-02 fully satisfied)
• DiagramLinkingIT integration test proves both positive (hash populated) and negative (empty fallback) cases
• mvn clean verify passes reliably -- 51 tests, 0 failures, 0 errors
• Fixed flaky test failures caused by EmptyResultDataAccessException in awaitility polling

Task Commits

Each task was committed atomically:

1. Task 1: Populate diagram_content_hash during ingestion and fix Surefire forks - 34c8310 (feat)

Plan metadata: (pending)

Files Created/Modified

• cameleer-server-app/src/main/java/com/cameleer/server/app/storage/ClickHouseExecutionRepository.java - Added DiagramRepository injection, diagram hash lookup in insertBatch
• cameleer-server-app/pom.xml - Added maven-surefire-plugin and maven-failsafe-plugin with reuseForks=false
• cameleer-server-app/src/test/java/com/cameleer/server/app/storage/DiagramLinkingIT.java - Integration test for diagram hash linking
• cameleer-server-app/src/test/java/com/cameleer/server/app/storage/IngestionSchemaIT.java - Added ignoreExceptions + increased timeouts
• cameleer-server-app/src/test/java/com/cameleer/server/app/controller/SearchControllerIT.java - Adjusted pagination assertion count

Decisions Made

• DiagramRepository injected via constructor into ClickHouseExecutionRepository -- both are @Repository Spring beans, so constructor injection autowires cleanly
• Used ignoreExceptions() in awaitility chains rather than switching from queryForObject to queryForList, since ignoreExceptions is the canonical awaitility pattern for eventual consistency
• Surefire AND Failsafe both need reuseForks=false -- ELK's LayeredMetaDataProvider static initializer poisons the JVM classloader for subsequent Spring Boot test contexts

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed flaky integration tests due to awaitility not retrying EmptyResultDataAccessException

• Found during: Task 1 (verification step)
• Issue: Awaitility's untilAsserted was not retrying EmptyResultDataAccessException thrown by queryForObject when data hadn't been flushed yet, causing intermittent test failures
• Fix: Added .ignoreExceptions() to all awaitility assertions that poll ClickHouse with queryForObject, and increased IngestionSchemaIT timeouts from 10s to 30s
• Files modified: DiagramLinkingIT.java, IngestionSchemaIT.java
• Verification: mvn clean verify passes with 51/51 tests green
• Committed in: 34c8310 (part of Task 1 commit)

2. [Rule 1 - Bug] Fixed SearchControllerIT pagination assertion count

• Found during: Task 1 (verification step)
• Issue: Pagination test asserted >= 8 COMPLETED executions but seed data only contains 7 COMPLETED (execs 2,4 are FAILED, exec 3 is RUNNING)
• Fix: Changed assertion to isGreaterThanOrEqualTo(7)
• Files modified: SearchControllerIT.java
• Verification: Test passes consistently
• Committed in: 34c8310 (part of Task 1 commit)

---

Total deviations: 2 auto-fixed (2 bugs) Impact on plan: Both fixes required for test reliability. No scope creep.

Issues Encountered

• Initial mvn clean verify had 3 test failures (DiagramLinkingIT x2, IngestionSchemaIT x1) all caused by EmptyResultDataAccessException in awaitility assertions. Root cause: awaitility was propagating the exception immediately instead of retrying. Fixed by adding ignoreExceptions().

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Phase 2 fully complete: ingestion, search, detail, diagrams, and now diagram-execution linking
• DIAG-02 requirement satisfied: transactions link to the RouteGraph version active at execution time
• Test suite stable at 51 tests with classloader isolation
