The previous entry referenced fields (id: String, primaryPersonName,
relatedPersonName) from an earlier design that was superseded during
spec review. Replace with the actual 13-field record shape implemented
in PR #826.

Fixes: @markus stale CLAUDE.md entry on PR #826

590b00d2d7 fix(timeline): add @Transactional(readOnly=true) to TimelineService.assemble()
Without the annotation, Hibernate closes its sub-transaction after
eventRepository.findAll() returns, leaving TimelineEvent entities
detached. Accessing ev.getPersons() or doc.getReceivers() on those
detached entities throws LazyInitializationException in production
(constitution §1.6). @DataJpaTest and @Transactional test classes
masked the bug by keeping an outer session alive.

Fixes: @felix / @markus review blockers on PR #826

3a174dd91b test(timeline): add integration tests for TimelineService + findByGeneration
Verifies PersonRepository.findByGeneration handles match, no-match (empty
list not NPE), and null-generation persons (excluded). Also confirms
TimelineService.assemble() returns a persisted curated event in the
correct year band against real Postgres via Testcontainers.

afd1f0b86b feat(timeline): add GET /api/timeline endpoint + 8-test controller suite
TimelineController exposes GET /api/timeline with @RequirePermission(READ_ALL)
and @Validated so @Min(0) on generation fires a 400. Delegates to
TimelineService.assemble(TimelineFilter). DomainException 404/400 propagate
via GlobalExceptionHandler (no extra mapping needed).

f08b09faeb feat(timeline): add TimelineService assembly + 24-test Mockito suite
Creates TimelineService.assemble(TimelineFilter): merges curated events

and archive letters (DocumentService) into a year-bucketed TimelineDTO.
WITHIN_BAND_ORDER Comparator tested standalone before assembly tests.
ArchUnit Rule 2 entry for ..timeline.. domain added in same commit.

de30f66a2d feat(timeline): add PersonService.getPersonsByGeneration + DocumentService.getAllForTimeline
PersonRepository.findByGeneration(Integer) — boxed to match nullable entity field.
DocumentRepository.findAllForTimeline() — Document.list entity-graph, single query.
Both services delegate with one-liner methods.

184fc9814a refactor(timeline): adapt TimelineEntryDTO to unified #777 shape
Replace the #776 DTO (primary/relatedPersonName + synthetic String id)
with the full #777 spec: kind, senderName, receiverName, eventId,
documentId, linkedPersonIds, title, eventDateEnd. Derived events now use
title=displayName, linkedPersonIds=[UUID...], eventId=null.

DerivedEventsAssemblyTest updated — all 16 tests pass.
