Protected behavior

Approved leave blocks check-in only on exact immutable leave_request_days, not every calendar date inside the request range. Concurrent duplicate punches return stable attendance rejection codes while preserving a single raw check-in and checkout.

Test method

Spring Boot migrates PostgreSQL 18.4, creates an active Intern only through public Account and SMTP services, and persists an Attendance-owned approved leave request plus one frozen allocation through JPA. A separate non-transactional test releases two threads simultaneously against each transactional punch endpoint.

Hand-derived expected result

For an approved 14–17 August range with only 17 August allocated, check-in on 14 August succeeds and 17 August returns APPROVED_LEAVE. Two simultaneous check-ins produce one success and one ALREADY_CHECKED_IN; two simultaneous checkouts produce one success and one ALREADY_CHECKED_OUT.

RED

Command

export JAVA_HOME=/opt/homebrew/opt/openjdk@25
export PATH="$JAVA_HOME/bin:$PATH"
export DOCKER_HOST=unix:///Users/sechmachine/.orbstack/run/docker.sock
./mvnw -Dtest=AttendancePersistenceIntegrationTest#approvedLeaveBlocksOnlyItsFrozenAllocatedDates test

Observed result

AttendanceException: APPROVED_LEAVE at AttendanceApplicationService.checkIn for
the unallocated 2026-08-14 range date.
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0
BUILD FAILURE
Process exited 1 because the query used the whole leave request range.

The repository-exception unit regressions separately failed because raw DataIntegrityViolationException and ObjectOptimisticLockingFailureException escaped the application boundary.

Observed result

AttendanceConcurrencyIntegrationTest: Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
PostgreSQL reported SQLSTATE 23505 on uq_attendance_records_intern_date; the caller
received ALREADY_CHECKED_IN. The checkout race returned ALREADY_CHECKED_OUT.

External-test boundaries

The tests do not implement the later leave workflow or account terminal-state transitions. They prove the current read/query boundary, exact PostgreSQL 18.4 allocation semantics, and duplicate-punch conflict translation.
