Meta / Extension Tables

The platform cannot ALTER an existing table, so extra fields live in 1:1 *_meta extension tables (see Architecture Decisions › Platform Constraints).

block_image_meta — The photo property of a block — image URL, display mode, focal anchor.
block_instance_photo — Per-instance photo override for a repeated block.
block_image_link_meta — URL-sourced photo metadata (resolved og:image link).
block_image_source_meta — Where a block's photo came from — camera, Reflow gallery, or URL.
block_photo_display_meta — Photo display settings — Fit / Zoom / Anchor mode and the title chip.
entry_calendar_meta — Polymorphic per-entry external-calendar metadata (entry_kind + entry_id).
entry_reminders — The one optional reminder per entry — offset and delivery method.
entry_invitees — Invitee email list per entry (polymorphic entry_kind + entry_id).
entry_icons — Optional display icon/emoji per entry (polymorphic).
task_reschedule_meta — Forgiveness-rollover bookkeeping per task (what rolled, when, how far).
