# HXP-008 — Conservation-Safe Attachment Profiles

Status: Validation Protocol 0.1

`RIGID-M1` uses a recessed or mechanically retained frangible capsule for hard goods. `FLEX-S1` uses a sewn or webbed anchor crossing a qualified leather or textile seam. `ART-M1` attaches only to a frame, backing, mount, case, or transport capsule by default. `CLOSURE-B1` bridges a package opening and authenticates the commissioned package-to-item relationship.

No universal adhesive claim exists. Each profile declares substrate family, preparation, geometry, service envelope, removal mechanism, destructive signals, permitted repair, and validation dossier.

Direct adhesive application to artwork is prohibited unless a named conservator, material assessment, owner authorization, reversible-treatment plan, and substrate-specific validation explicitly create a separate profile. Industrial destructible adhesives must not be described as conservation-safe merely because they are tamper evident.
