First external integrator agreement — trail committed on mainnet

Today we signed a revenue share agreement with our first external integrator, a financially-meaningful agent execution platform built on the Mycelium stack.

When the agreement was signed, a trail was automatically committed to Arbitrum mainnet via the DocuSeal webhook — no manual intervention. The agreement itself is the negotiation_ref. Every subsequent trail from this integrator inherits this one as root.

This is the model working end-to-end in production: agreement → on-chain anchor → verifiable audit chain from day one.

delegation-chain-ref v1.0 — multi-hop delegation chain verification

Formalizes how a delegation chain of N hops (A→B→C→D) is verified end-to-end without trusting any intermediary. Per-hop parent_delegation_ref enables independent backward traversal from leaf to root. Byte-verified conformance fixture (3-hop giskard-self→pioneer→lightning→soma-agent) in docs/spec/fixtures/delegation-chain-ref-v1.fixture.json.

cross-system-verification v1.0 — trustless trail verification

Any external stack verifies a Mycelium Trail without calling Giskard. Four canonical steps: recompute action_ref from preimage, match trail record, fetch OP_RETURN anchor from public chain RPC, match payload. No Giskard endpoint required. Byte-verified conformance fixture in docs/spec/fixtures/cross-system-verification-v1.fixture.json.

composition-ref v1.0 — end-to-end authorization lifecycle

Formalizes how delegation-ref + revocation-ref + dual-timestamps (authority_verified_at_ms + revocation_check_at_ms) compose into a single verifiable unit. Byte-verified conformance fixture in docs/spec/fixtures/composition-ref-v1.fixture.json.

action-ref-v1.0

Stable release of the action_ref primitive specification.

SHA-256(JCS({agent_id, action_type, scope, timestamp})) — content-addressed identifier for agent actions.

Spec: docs/spec/action-ref.md
Conformance fixtures: examples/conformance/

Verified byte-identical by: APS (aeoess), SafeAgent (azender1), Nobulex (arian-gogani, 16/16), AlgoVoi (chopmob-cloud), andysalvo verifier (5/5 PASS).
