PR-4 — CompleteVerification

Status: DRAFT / DO NOT MERGE

Exact stacked parent: PR #272 @ bf29570cf4ae189de93f38a9018e124c2136c687

Exact PR-4 head: 6407db1b0c4176f67a1d7ecbb16eca77d131d87e

Topology: merge-base is exactly bf29570cf4ae189de93f38a9018e124c2136c687; PR-4 is 8 commits ahead / 0 behind, with 6 changed files.

Purpose

Close the frozen verification chain without converting verification into admission:

DecisionReceipt
+ ExecutionReceipt
+ EffectWitness
+ EffectVerificationResult
+ EffectReceipt
+ exact TransitionIdentity
    -> CompleteVerificationResult

CompleteVerificationResult is a verifier artifact only. It is not an authority receipt, AdmissionRecord, causal claim, or production admission.

Implemented

• new nominal CompleteVerificationResult with mandatory discriminator COMPLETE_VERIFICATION_RESULT_V1;
• dedicated result hash domain AEGIS_COMPLETE_VERIFICATION_RESULT_V1;
• separate PR-4 policy commitment domain AEGIS_COMPLETE_VERIFIER_POLICY_COMMITMENT_V1, preserving PR-3 verifier-policy semantics;
• exact nominal input typing for TransitionIdentity, DecisionReceipt, ExecutionReceipt, EffectWitness, EffectVerificationResult, and EffectReceipt;
• PERMIT required; DENY / DEFER can never yield TRUE;
• cross-transition and execution-instance anti-splicing;
• existing PR-3 EffectVerifier.verify_effect(...) is recomputed rather than replaced;
• recomputed verification root must equal the supplied EffectVerificationResult.root and EffectReceipt.effect_verification_root;
• EffectReceipt is bound back to the exact witness for witness digest, pre/post state, observation provenance, adapter identity/version, transition, execution instance, and active PR-3 verifier policy;
• admission-policy commitment must remain exact;
• TRUE iff every ordered CompleteVerification obligation is TRUE.

TDD evidence

Initial RED candidate 9f75bf9a1a9e751b8caba45bd73516ec238578c7 was executed on independent hosted runner tarikskalic33/info run 32247308632 and failed for the intended missing harness.sdk.complete_verifier module.

After the initial 25/25 GREEN, adversarial review discovered a real binding gap: a structurally valid forged EffectReceipt could retain valid witness/verification roots while changing post-state/provenance/adapter metadata. A second RED witness on candidate 094ed852529335c41e0b9d94ff11982d01fdf2f8, run 32247667019, reproduced all four bypasses as CompleteVerification=TRUE. The production fix then bound those fields back to the exact EffectWitness lineage.

External exact-head witness — ESTABLISHED

Independent GitHub-hosted runner tarikskalic33/info run 32247833991 checked out exact AEGIS candidate:

Preserved epistemic topology

DecisionReceipt -> ExecutionReceipt
ExecutionReceipt -/-> EffectReceipt

WorldObservation
  -> EffectEvidence
  -> VerifyEffect
  -> EffectReceipt
  -> CompleteVerification

CompleteVerification -/-> CausalClaimAdmission
CompleteVerification -/-> AtomicAdmission
CompleteVerification -/-> EffectBoundAdmission
CompleteVerification -/-> ProductionAdmission

No generic EffectReceipt producer is introduced. Provider/model output remains evidence only, never authority.

Separate debt surfaced by witness

The MCP npm ci completed and its tests passed, but npm reported 5 dependency vulnerabilities (1 low, 2 moderate, 2 high). This is not erased by the successful PR-4 functional witness and should remain separate dependency-security debt.

The claims ledger also remains self-consistent with existing stale-warning claims; PR-4 does not promote or refresh those unrelated claims.

Deliberately not performed

• no mutation of main, feat(automaton3): bind transitions and separate decision/execution/effect receipts #268, feat(automaton3): add independent effect observation #270, feat(automaton3): verify effect before issuing EffectReceipt #272, SOL: governed cross-platform control plane foundation #225, or feat(sol): frontier provider mesh with proof-carrying execution #264;
• no production provider calls;
