Upstream integration

Approved in. Traceable through. Reversible out.

P003 consumes signed, versioned export packages from authoritative programmes. Every record is authenticated, validated, staged, and promoted as one controlled snapshot—or the whole package is quarantined.

Authority contracts

One boundary. Programme-specific truth.

All programmes use the same transport and integrity envelope. Each retains its own allowed record types, approval authority, lifecycle, and substantive ownership.

01

Receive

Accept a bounded package without placing records in the public index.

02

Authenticate

Verify the registered programme, signing key, signature, and monotonic sequence.

03

Validate

Check schema, ownership, approval, visibility, dates, hashes, identifiers, and prohibited material.

04

Quarantine

Isolate the entire package when any control fails; expose no raw content in diagnostics.

05

Stage

Build a candidate snapshot and run domain, accessibility, link, search, and regression checks.

06

Promote

Move one immutable snapshot atomically into the public platform after accountable approval.

07

Rollback

Restore the last verified snapshot without rewriting upstream history.

Fail-closed quarantine

No partial trust.

A single invalid, unapproved, mismatched, duplicate, expired, future-effective, prohibited, or unauthenticated record prevents the entire package from reaching staging. Diagnostics retain identifiers and reason codes—not rejected content.

Promotion and rollback

Publication changes as one snapshot.

Successful validation creates a candidate release with immutable lineage from public route back to package and source record. Promotion updates content, search, sitemap, citations, and navigation together. Rollback selects an earlier verified snapshot; it never edits upstream history.
