# Private / Controlled Materials Notice v8.4

The publication transport package separates public payload from controlled references.

## Public payload

Public payload includes completed public volume packages, source-only public TEX layers and the v8.3 master index/site bundle.

## Controlled references

Large root packages, site source packages, SDK/source builds, restored site archives and auxiliary source bundles are checksum-bound but are not copied into the public transport payload by default. This prevents accidental publication of working, private, draft, internal, or oversized materials.

## Rule

A controlled file may be moved into the public payload only after a separate release gate confirms: authorial approval, public/private split, hash control, filename normalization, site route and rollback point.
