WalkthroughCommand target lookup now supports asynchronous UUID resolution for uncached names. Season cleaning rejects blank season IDs and updates handling for scheduling and callback failures. The change adds tests across command, cleaning, plugin, permission, listener, and store behaviour. Maven configures JaCoCo coverage checks, and CI uploads coverage reports.

Addressed the worker-Error notification finding. The caller receives one null result before the original Error propagates; callback or scheduling failures are suppressed on that original Error, and the in-flight slot stays released. Added regressions for callback failure and scheduler rejection. Also verified the offline lookup against Paper 1.21.10: its UUID resolver honors proxy online-mode settings, which can differ from the backend online-mode flag. Uncached lookup now runs that resolver asynchronously and checks the returned identity’s local history on the main thread. The proxy regression failed before this adjustment. Full clean verify passes 130 tests with 403/403 runtime lines and 1,823/1,823 instructions covered. Runtime JAR validation passes. |

Fixed the outside-diff stamp-task submission finding. Both fatal worker errors and rejected completion-task submission now use the same failure notification helper, release the reservation, notify once where the plugin is enabled, and preserve the original throwable if notification fails. Two additional regressions failed before the fix and pass afterward. Full clean verify: 132 tests, 100% runtime line and instruction coverage. |

Both build and release workflows now require a non-empty JaCoCo XML report immediately after Maven verification. The existing conditional uploads remain so failed builds can still attach reports. Verified the check passes with the generated report and fails for both missing and empty reports. |

PermCleaner now enforces 100% executable runtime line coverage, up from 17.33%. The suite covers lifecycle wiring, commands, permission retention/removal, asynchronous cleanup and real SQLite season stamps. Build and release workflows upload JaCoCo reports, with no production exclusions.
Regression fixes in this PR:
Validation: Java 21
mvn -o -B --no-transfer-progress clean verify: 134 tests pass, 405/405 runtime lines and 1830/1830 instructions covered; branches 250/256. Runtime JAR validation andgit diff --checkpass. Five cleanup regressions and three save/command regressions failed before the fixes and pass afterward.CodeRabbit follow-up: worker Errors notify the caller once before propagating, preserving the original Error if notification also fails. Additional proxy regression delegates uncached identities to Paper’s proxy-aware resolver instead of deriving UUIDs from the backend online-mode flag.
The completion-task submission failure also notifies the caller before rethrowing, with regressions for successful notification and a throwing consumer.
Ordinary worker failures also retain callback/submission failures as suppressed exceptions in the logged error while releasing the reservation; both paths have regression tests.
