 7. Personal report parity track (weather visuals, live news path, commute path, calendar parity matrix) - in progress (`2026-05-10` first live-news provider slice implemented)
 8. Holidays and seasonal personality behavior built on the new memory/proactivity foundation
+   - system holidays should come from an up-to-date provider and merge with loop-scoped custom holiday records
+   - allow disabled holiday records to suppress reminders for people who do not celebrate a holiday
+   - birthdays and other personal dates should flow into the same loop-scoped holiday list once authoring is wired up
 9. Durable memory persistence path (multi-tenant backing store)
   - reference design captured in `docs/persistence-architecture.md`
   - store contracts are now tightened around account/loop/device/person scoping, revision tracking, and explicit load/save boundaries

+# Holiday Architecture
+
+Pegasus exposed holidays as a loop-scoped list synchronized into `/jibo/holidays`.
+
+In OpenJibo, the holiday path now follows the same broad model:
+
+- system holidays come from a live holiday source
+- custom holidays are loop-scoped
+- suppressed holidays are represented as disabled records
+- the cloud protocol returns the merged list for `PersonListHolidays`
+
+Current behavior:
+
+- `Person/ListHolidays` uses the loop from the request when available
+- if no loop is supplied, the cloud falls back safely instead of throwing
+- the merged list is built from system holidays plus any custom loop entries
+
+Notes:
+
+- `IsEnabled = false` can be used to suppress a holiday later
+- birthdays and other personal events can be added as loop-scoped custom records
+- the current system holiday source uses Nager.Date with a safe local fallback for uptime

 - port holiday-aware personality responses as a visible extension of the new persona slice
 - start with a small, source-backed set (for example birthdays/holidays already represented in legacy data paths)
 - ensure holiday responses feel characterful while still routing through stock-compatible payloads
+- use a loop-scoped merged holiday list in the cloud protocol so system holidays and custom person holidays can coexist
+- source system holidays from a live holiday provider and keep `IsEnabled = false` records available for holiday suppression
+- keep birthday/custom holiday authoring aligned with person memory so future proactivity can suppress or promote holidays per loop
