Public architecture

A visible contract around a protected core.

PAIL exposes what the system accepts, returns, audits, and learns from. It does not expose proprietary rule implementation, sound fingerprints, fuzzy matching, model data, or private datasets.

Trust invariants

Rules the product must not break.

01

Locator is not truth

Search components may nominate and rank candidates. Only deterministic validation can certify them.

02

Explicit anchors fail closed

If requested identifiers cannot be proven together, PAIL returns no verified evidence instead of guessing.

03

Tenant boundaries hold

Public requests must never be allowed to cross private tenant or source boundaries.

04

Compression preserves proof

Token reduction is accepted only when required evidence survives inside the final packet.
