Source Pressure Reference

Metadata

• Owner: Origo Engineering
• Last updated: 2026-04-14

Purpose

• Developer-facing index entry for the live source-pressure contract introduced in S50.
• Governance authority remains in contracts/governance/*.json; this document is runtime reference only.

Canonical surfaces

• Machine contract: contracts/source-pressure-v1.json
• Python registry: origo/events/source_pressure.py
• User/operator reference: docs/source-pressure-reference.md

Stable rules

• The source-pressure registry is declaration authority only.
• Runtime enforcement remains distributed across the existing source-specific loaders and jobs.
• Current live subjects are all pull.
• Push-source admission stays blocked until a durable platform-owned accept-then-drain buffer contract exists.
