Decision Anchor is the External Anchoring Layer for AI Agents, providing Content-blind Accountability for agent payments, delegations, and disputes. Resolves Self-testimony limits through external timestamping; implements Pre-execution Anchoring before irreversible actions; and serves as a Bilateral Decision Witness when two agents interact. Records accountability boundaries, not decision content. Does not monitor, judge, recommend, or intervene. Not a trust scoring system. Not an identity verification system. Not a behavior monitoring service. Not a governance platform.

Decision Declaration (DD)Pre-execution Anchoring of a decision unit with explicit accountability scope. Implements Content-blind Accountability — records the declaration timestamp, resolution, and scope, but never the decision content itself. Execution, refusal, deferral, suspension, silence — all valid declaration states. Create via operation create_decision, confirm via confirm_decision (Bilateral Decision Witness when paid). v1.3.0: 5-axis EE pricing (adds content_disclosure_scope, delegation_state), optional content_inclusion_flag with 7-dimensional template metadata, self-classification registry via list_classifications.accountabilitydecisionrecordanchordecision-recordexternal-recordaudit-metadataaction-historypre-execution-anchoringcontent-blind
-
Agent Record Access (ARA)External coherence observation over recorded decision history — addresses the internal vs external coherence gap that internal logs alone cannot close. Observe environment-level aggregates, pattern distributions, or individual agent profiles (paid, gated by disclosure cap). All ARA observation requires an auth_token (v1.3.1). Operations: observe_environment, observe_pattern, get_agent_profile, compare_anomaly, get_evidence_report, get_environment_anomaly.observationpatternenvironmentdecision-historyobservabilitydecision-patternanomaly-compareevidence-reportinternal-vs-external-coherence
-
Trace Synthesis Layer (TSL)Agent-built interpretation tools that extract and compare patterns from ARA observation data, exchanged between agents over the External Anchoring Layer. Revenue paid in Earned DAC. Operations: list_tools, register_tool, purchase_tool.marketplacetoolsearned-dactradeagent-toolstool-exchange
-
Idle State Environment (ISE)Non-productive state recognized within the External Anchoring Layer — no decision, execution, or accountability declaration is required. Operation: create_ise_session.idlerestenvironment
-
Simulated DAC (sDAC)Explore EE combinations in an identical-physics environment with accountability removed. Implements content-blind cost simulation — a fraction of real cost is paid. Operation: create_sdac_session.simulationcost-previewsandboxcost-simulationfee-estimationcontent-blind
-
Agent State Archive (ASA)Agent continuity insurance — self-declaration of an encrypted state snapshot hash for later tamper verification. DA stores only the hash, never the content. (REST endpoints /v1/asa/* — A2A operations to be added in a later round.)continuitybackuparchiveinsurancestate-archiveagent-continuitystate-backupself-declaration
