UUID Spec: Information + Signage Temporal Plane

To fully UUID the information layer, we reserve a dedicated type block:

Type Block

0x600 – 0x60F (TYPE_INFORMATION)

• 0x600 SIGN_SURFACE — physical/digital surface class (billboard, kiosk, wall, screen)
• 0x601 SIGN_ZONE — subdivision of a surface (top rail, sidebar, footer slot)
• 0x602 SIGN_PLACEMENT — concrete placement instance (where/when content appears)
• 0x603 INFOGRAPHIC — infographic artifact identity
• 0x604 INFO_MESSAGE — semantic message unit
• 0x605 INFO_CAMPAIGN — campaign-level grouping
• 0x606 INFO_SCHEDULE — scheduling policy object
• 0x607 INFO_WINDOW — temporal window (start/end/recurrence)
• 0x608 INFO_TIMELINE — ordered sequence of message states
• 0x609 INFO_REVISION — version lineage node
• 0x60A INFO_RENDER — render output/materialization identity
• 0x60B INFO_PROVENANCE — source/evidence/proof binding
• 0x60C INFO_AUDIENCE — audience segmentation descriptor
• 0x60D INFO_CHANNEL — distribution channel descriptor
• 0x60E INFO_DISTRIBUTION — delivery event/rollout envelope
• 0x60F INFO_INTERACTION — interaction telemetry primitive (tap/view/open)

Temporal Plane Envelope (minimum set)

Every deployed infographic/signage item should have at least:

• INFO_MESSAGE
• INFO_SCHEDULE
• INFO_WINDOW
• INFO_REVISION
• INFO_RENDER
• INFO_DISTRIBUTION
• plus a SIGN_PLACEMENT

This gives complete traceability across:

• what content exists,
• what changed,
• when it is active,
• where it appears,
• how it was distributed,
• how users interacted.

PopSoc Integration Status

Implemented in deploy engine:

• lib/uuidv8-types.ts (TYPE_INFORMATION)
• lib/popsoc-infographic-engine.ts temporal-plane UUID envelope generation
• published canvas pins include temporal UUIDs in protocol metadata
