Phosra Spec
The interoperability standard for child online safety, made of nine layers.
One Charter and eight runtime capabilities. Each layer is a named contract that platforms, parental controls, and regulators can implement against — so the same parental policy works everywhere a child goes online.
The nine layers
Every rule in the Phosra registry is implemented by exactly one named capability. Read the spec for any layer below.
Phosra Charter
The open child-safety specification (PCSS v1.0).
Phosra Bearing
Reads age signals across OS, app, and household.
Phosra Lens
Refracts content, AI, and privacy into safety bands.
Phosra Threshold
Verifiable parental consent and access boundaries.
Phosra Aegis
Hard blocks for prohibited content and apps.
Phosra Herald
Parent-facing notifications, reports, and alerts.
Phosra Custody
Data minimization, retention, and deletion rights.
Phosra Verdict
Algorithmic transparency, audit, and dark-pattern interventions.
Phosra Notary
Cryptographically signed events and regulatory reporting.
Resources
Read, govern, track, verify.
The PCSS surface is more than the runtime layers — here's the governance, history, and conformance work around the spec.

Build to the spec, not to the statute.
The Charter defines the contract. The eight runtime capabilities make it real. Adopt the spec once, stay compliant as the laws evolve.
