Six new tests in sync.test.ts under the "field-meta overhaul (F1-F4-fu)"
block, verifying the architectural promises of the 2026-04-26 sync
field-meta overhaul end-to-end:
- deriveUpdatedAt returns max(__fieldMeta[*].at)
- deriveUpdatedAt gracefully handles legacy / null records
- Dexie creating-hook stamps __fieldMeta + _updatedAtIndex on every
local write
- Dexie updating-hook bumps __fieldMeta only for changed fields and
syncs _updatedAtIndex with the latest at
- SYSTEM_BOOTSTRAP-stamped local insert produces origin='system' (the
fallback path in userContextStore + kontextStore)
- Bootstrap-twin race scenario: local SYSTEM_BOOTSTRAP row + later
server insert collapses via field-LWW with no conflict surface
Also re-exports SYSTEM_BOOTSTRAP from $lib/data/events/actor for
parity with the other SYSTEM_* sentinels.
35/35 sync.test.ts pass (29 prior + 6 new).
