Association-dependent instrument plane · published catalog

Capabilities become instruments.

Reframe is becoming an agentic ecosystem: governed MIDI2 instruments can be discovered, admitted, composed, observed, and reused under Reframe's host authority.

The perspective

This is the published instruments.fountain.coach surface. It is a catalog and architectural previz, not an operational marketplace.

Fountain Coach identity

Every public instrument carries a company-owned identity and an explicit MIDI Association identity status.

MIDI2 contract

Operations, lifecycle, permissions, topology, data movement, and evidence lineage remain machine-readable.

Honest admission

Risk disposition, security review, live acceptance, and release are separate states—not one “verified” badge.

The governed path

Fountain Coach identity
→ MIDI Association identity
→ MIDI2 instrument contract
→ scenario evidence
→ risk disposition
→ catalog publication
→ optional released instrument

Fountain Coach owns implementation, evidence, risk decisions, and release authority. The MIDI Association supplies standards and identity/licensing mechanisms. Association overview · SysEx ID policy · Logo licensing

First instrument

Reframe-owned Codex Auth Instrument

A host-owned authentication capability that makes the agentic instrument boundary visible from Copilot intent to a redacted terminal result.

Identity

codex.auth.instrument
codex/auth.login.start

Current state

Executable · risk-managed · security review pending

Claim boundary

No MIDI Association certification, independent security review, live acceptance, or released-build claim.

What this publication does not claim

Catalog publication does not itself establish security certification, safe operation in every environment, MIDI Association logo permission, live acceptance, or commercial availability. Those claims require their own authority and evidence.
