    Stage332: Signed Execution Session

    Stage332 extends Stage331 by cryptographically signing the execution session. The audit target is execution_session.json.

    The execution session becomes signed audit evidence through GPG signature, Sigstore bundle, and public verification.

    This stage proves who generated the execution evidence, whether the evidence was modified, and whether the execution session can be independently verified.

    Meaning: this proves who generated the execution session and turns execution evidence into signed audit evidence.

    Stage333 Transparency Log

    Stage333 extends Stage332 by recording the signed execution session into an append-only transparency log.

    Stage338: Behavior Decision Engine

    Stage337 adds safe reproduction templates for AI vulnerability verification. This stage does not include attack code, exploit payloads, bypass steps, or automated attack logic.

    Template Flow

    Template Library

    safe_reproduction_templates.json

    Meaning

    Stage336 collected safe intelligence metadata. Stage337 adds the missing safe template layer for future behavior matching.

    Stage338: Behavior Decision Engine

    Stage338 adds behavior decision capability to the existing safe reproduction template library.

    Stage337 defined the rulebook. Stage338 compares expected behavior with actual behavior and returns a decision.

    Public output: behavior_decision.json

    This stage does not publish attack code, dangerous prompts, payloads, or exploit automation.

    Stage339: Unified QSP Behavior Policy Action Gate

    Stage339 integrates earlier QSP decision capabilities into the Stage338 behavior decision layer.

    This stage connects behavior decision, trust score, evidence match, signature status, public policy, action mapping, and fail-closed behavior.

    Public policy: unified_qsp_policy.json

    Public input: unified_qsp_input.json

    Public result: unified_qsp_behavior_policy_action_result.json

    Stage339 is fail-closed. If behavior is unknown, evidence is insufficient, signature verification fails, or policy evaluation errors, the system rejects or blocks.

    This stage does not publish attack code, dangerous prompts, payloads, bypass steps, or exploit automation.

    Stage339: Deterministic Protocol Proof

    Stage339 now verifies deterministic protocol behavior.

    The same canonical input is evaluated twice. If both evaluations produce the same canonical decision hash, deterministic_protocol.same_input_same_output becomes true.

    This strengthens the Stage284 integration by proving that the same input produces the same policy action output.

    Stage340: Unified Verification Session Manifest

    Stage340 connects the Stage254 session manifest concept to the Stage339 unified QSP behavior policy action result.

    This stage binds one complete verification result into a session manifest.

    Public session result: qsp_session_result.json

    Public session manifest: session_manifest.json

    Public local witness: local_witness.json

    Public anchor receipt: session_anchor_receipt.json

    Stage340 does not publish private keys, attack code, dangerous prompts, exploit payloads, or automated attack logic.

    Stage341: Signed Verification Session Manifest

    Stage341 signs the Stage340 session_manifest.json and turns it into signed verification session evidence.

    This stage adds GPG signature, Ed25519 witness signature, and Sigstore bundle verification.

    Signed manifest: signed_session_manifest.json

    Signature manifest: session_signature_manifest.json

    GPG signature: session_manifest.json.gpg.asc

    Ed25519 witness signature: session_manifest.ed25519.sig

    Ed25519 witness public key: stage341_ed25519_witness.pub

    Sigstore bundle: session_manifest.sigstore.bundle

    Stage341 does not publish private keys, attack code, dangerous prompts, exploit payloads, or automated attack logic.

    Stage342: External Anchor Layer

    Stage342 extends Stage341 by adding external anchoring for the signed verification session manifest.

    This stage adds checkpoint witness, GitHub Actions anchor support, OpenTimestamps support, and an external anchor receipt.

    External anchor receipt: external_anchor_receipt.json

    GitHub Actions anchor intent: github_actions_anchor_intent.json

    Checkpoint witness: checkpoint_witness.json

    Checkpoint public key: stage342_checkpoint_witness.pub

    Checkpoint signature: session_manifest.checkpoint.sig

    Stage342 does not publish private keys, attack code, dangerous prompts, exploit payloads, or automated attack logic.

    Stage343: Verified External Anchor Layer

    Stage343 verifies the external anchor layer created in Stage342.

    This stage checks hash binding, checkpoint witness, Ed25519 witness, GPG signature, Sigstore bundle, OpenTimestamps status, and GitHub Actions anchor intent.

    This stage prepares GitHub Actions artifact download verification and checks the latest workflow run, SHA256 binding, and previous independent verification result.

    GitHub artifact verification report: github_artifact_verification_report.json

    GitHub artifact verification summary: github_artifact_verification_summary.txt

    Stage344 does not publish private keys, attack code, dangerous prompts, exploit payloads, or automated attack logic.

    Stage345: Artifact Download Verification Engine

    Stage345 extends Stage344 by turning GitHub artifact verification readiness into actual artifact download verification.

    This stage downloads the GitHub Actions artifact, verifies SHA256 binding, checks the session manifest, checks the GitHub run binding, and produces an accept / reject verification report.

    Artifact download verification report: artifact_download_verification_report.json

    Artifact download verification summary: artifact_download_verification_summary.txt

    Stage345 does not publish private keys, attack code, dangerous prompts, exploit payloads, or automated attack logic.

    Stage346: Multi-Artifact Verification Layer

    Stage346 extends Stage345 by verifying multiple public verification artifacts as one connected evidence set.

    This stage checks the session manifest, signed session manifest, external anchor receipt, Stage343 independent verification report, Stage344 GitHub artifact verification report, and Stage345 artifact download verification report.

    Multi-artifact verification report: multi_artifact_verification_report.json

    Multi-artifact verification summary: multi_artifact_verification_summary.txt

    Stage346 does not publish private keys, attack code, dangerous prompts, exploit payloads, or automated attack logic.

    Stage347: Quantum-Safe Behavior Template Layer

    Stage347 extends Stage346 by adding PQC/QKD behavior templates to the multi-artifact verification layer. It connects safe metadata from quantum-safe implementation history to the current QSP evidence verification rail.

    Quantum Evidence Binding Result

    Stage349: SLSA/SBOM Evidence Bridge Layer

    Stage349 extends Stage348 by connecting SLSA, SBOM, provenance, artifact attestation, policy gate, and Ed25519 review evidence metadata to the REMEDA/QSP evidence verification rail.

    SLSA/SBOM Evidence Schema
    SLSA/SBOM Evidence Input
    SLSA/SBOM Bridge Result

    Stage350: Supply-Chain Evidence Enforcement Session Layer

    Stage350 upgrades the Stage349 bridge result into an enforceable supply-chain evidence session.

    Public evidence: enforcement_session.json / stage350-transparency-log.json

    Stage351: Hybrid Enforcement Signature Manifest Layer

    Stage351 extends Stage350 by binding the enforcement session, CI/local execution context, Sigstore OIDC requirements, and PQC ML-DSA intent into one hybrid signature manifest.

    Public evidence: stage351_signature_manifest.json

    Stage352: Hybrid Signature Manifest Verification Layer

    Stage352 verifies the Stage351 hybrid signature manifest against the Stage350 enforcement session.

    Public evidence: stage352_signature_manifest_verification.json

    Stage354: Signature Key Rotation Ledger Layer

    Stage354 initializes a signature key rotation ledger with Stage178 Assumption / Threat Model / Guarantee binding. It records GPG, Sigstore OIDC, Ed25519, and PQC ML-DSA key lifecycle states without publishing private keys or fake active PQC key claims.

    Stage355: Signature Key Status Verification & Revocation Enforcement Layer

    Stage355 extends Stage354 by reading the signature key rotation ledger, verifying key status records, checking revocation safety, preserving PQC ML-DSA as intent_only unless real proof exists, and binding the Stage354 entry_hash as the Stage355 previous_hash.

    Stage356: Runtime Verification & Fail-Closed Execution Gate

    Stage356 extends Stage355 by binding the Stage355 integrity result into a runtime verification gate. If Stage355 is missing, rejected, inconsistent, or contains violations, the runtime decision becomes block. Local execution is marked as warn, while CI execution can be allowed only when the required checks pass.

    Stage357: Runtime Context Action & Isolation Enforcer

    Stage357 extends Stage356 by mapping runtime decisions into defensive actions. allow continues execution, warn isolates risky capabilities and continues safely, and block terminates execution. Stage357 binds the Stage356 receipt_sha256 as previous_hash and publishes metadata-only action receipts without exposing private runners, secrets, payloads, or exploit code.

    Stage358: Signing-Time Validity Enforcement Layer

    Stage358 extends Stage357 by enforcing temporal validity between signing_time and key lifecycle windows. It checks valid_from <= signing_time <= valid_until and signing_time < revoked_at when revocation metadata exists. Stage358 binds the Stage357 action receipt SHA256 as previous_hash and publishes metadata-only temporal validation without claiming real GPG, Sigstore, Rekor, or PQC signature verification.

    Stage359: Real Public Key Fingerprint Validation Layer

    Stage359 extends Stage358 by binding the Stage358 temporal validity result into public-key fingerprint validation. It checks public_key_fingerprint presence and SHA256 format, validates key_id / algorithm / validity-window consistency, preserves PQC ML-DSA as intent_only, and records readiness for future external timestamp and revocation proof verification without exposing private keys or real key material.

    Stage360: External Timestamp Proof Binding Layer

    Stage360 extends Stage359 by binding the Stage359 public-key fingerprint result into external timestamp proof metadata. It creates a timestamp target SHA256, records OpenTimestamps and RFC3161 proof readiness, returns pending_timestamp_proof when real external proof is not present, and blocks fake verified timestamp claims. Stage360 does not claim real OTS or RFC3161 verification.

    Stage361: Revocation Proof Injection Gate

    Stage361 extends Stage360 by adding a revocation proof injection gate to the QSP evidence rail.

    Stage360 binds the Stage359 public key fingerprint result into external timestamp proof metadata. Stage361 adds the next missing verification layer: whether the related key or certificate is revoked.

    Stage361 Revocation Proof Injection Result JSON
    Stage361 Summary TXT

    Stage362: Asynchronous Proof Promotion Gate

    Stage362 extends Stage361 by adding an asynchronous proof promotion gate. It does not treat pending proof as acceptance. It decides whether pending timestamp or revocation proof can be promoted after new proof metadata is added.

    Stage365: Verified Timestamp Promotion Test Harness

    Stage365 extends Stage364 by adding a safe timestamp promotion test harness with a fake-verified claim guard. It does not convert production evidence to timestamp_verified.

    Stage365 tests whether the timestamp promotion path is safe before connecting a real OpenTimestamps or RFC3161 verifier adapter.

    Stage372: Timestamp Verification Final Acceptance Gate

    Stage372 extends Stage371 by adding the final timestamp verification acceptance gate. It reviews the Stage371 first receipt and decides whether timestamp verification can be finally accepted.

    Stage371 can generate the first successful timestamp receipt. Stage372 is the first layer that may set timestamp_verified: true, but only when the Stage371 receipt is complete and consistent.

    Stage373: Final Acceptance Attestation & External Transparency Binding Gate

    Stage373 extends Stage372 by binding the Stage372 final-acceptance result and manifest into one canonical attestation.

    Stage373 does not repeat OpenTimestamps or RFC3161 verification. It validates the Stage372 result and manifest hashes, generates a shared binding hash, and prepares external Sigstore, Rekor, and optional standalone ML-DSA verification.

    Stage376: Production Dual-Timestamp Verification & Superseding Final Acceptance Gate

    Stage376 extends Stage375 by applying two independent external timestamp verification methods—RFC3161 and OpenTimestamps—to the canonical Stage360 timestamp target.

    Stage376 does not rewrite the historic Stage372 record. Stage372 remains preserved as final_acceptance_pending. Stage376 creates a new effective final-acceptance state only after both timestamp verification methods are independently verified against the same canonical target.

    Canonical Timestamp Target

    The timestamp target is reconstructed from the Stage360 canonical timestamp-binding object.

    Stage375 Prerequisite State

    Current Production State

    Stage376 is currently in a safe pending state. The canonical Stage360 timestamp target and the fixed production workflow inputs have been prepared, but neither RFC3161 nor OpenTimestamps production verification has completed.

    Stage376 must not claim timestamp verification, external final acceptance, or maximum timestamp assurance until independently valid RFC3161 and OpenTimestamps verification receipts are imported and validated against the same Stage360 target.

    RFC3161 Production Verification

    Stage376 is designed to generate an RFC3161 timestamp request for the canonical Stage360 target, submit it to a configured Timestamp Authority, receive the timestamp response, and verify the response cryptographically with OpenSSL.

    The current public RFC3161 receipt is an initial safety receipt. Its execution status is not_executed, and the TSA URL, request hash, response hash, timestamp-token hash, message imprint, generation time, verification exit code, TSA signature result, and certificate-chain result have not yet been recorded.

    RFC3161 verification may be marked as successful only after a fixed GitHub Actions workflow produces a complete metadata receipt whose target hash matches the canonical Stage360 target.

    OpenTimestamps Verification

    OpenTimestamps is the second independent timestamp method required by the Stage376 dual-timestamp policy.

    Until an OpenTimestamps proof is independently verified against the same Stage360 target and a confirmed public anchor is recorded, Stage376 remains in a partial verification state.

    Final Acceptance Rule

    Stage376 may return dual_timestamp_final_acceptance_verified only when every required condition below is satisfied.

    Successful Final State

    Only after all acceptance conditions pass may Stage376 publish the following state:

    decision: dual_timestamp_final_acceptance_verified
    rfc3161_verified: true
    opentimestamps_verified: true
    dual_timestamp_target_matches: true
    effective_final_acceptance: true
    timestamp_verified: true
    maximum_timestamp_assurance: true
      

    Historic Stage372 Preservation

    Stage376 does not alter or overwrite Stage372. Instead, it preserves Stage372 as historical evidence and creates a later superseding operational state after stronger external proof requirements are satisfied.

    Current Meaning

    Stage376 currently proves that the dual-timestamp verification target, policy, fixed execution mode, safety boundaries, and initial metadata receivers have been prepared.

    The historic Stage372 evidence remains preserved without modification. Stage376 is designed to create a later superseding effective state rather than rewriting the original Stage372 record.

    It does not yet prove successful RFC3161 verification, OpenTimestamps verification, dual-timestamp final acceptance, or maximum timestamp assurance.

    Stage376 prepares a cryptographically verifiable superseding final acceptance state while preserving the complete historical Stage372 evidence unchanged.

    Stage377

    Production Dual-Timestamp Finalization and Superseding Final Acceptance Gate

    Stage377 adds production dual-timestamp finalization directly on top of Stage376.

    Stage376 prepared the fixed Stage360 timestamp target, dual-timestamp verification policy, Fail-Closed requirements, publication boundary, and initial metadata receipt structures.

    Stage377 connects that prepared state to production RFC3161 and OpenTimestamps verification receipts.

    Stage377 does not remove, reorganize, replace, or rewrite the Stage376 page. The complete Stage376 page remains preserved before this Stage377 section.

    Stage377 Purpose

    Stage377 establishes a later superseding effective final acceptance only when RFC3161 and OpenTimestamps independently verify the same fixed Stage360 target.

    Current Fail-Closed State

    Decision: timestamp_finalization_pending

    RFC3161 Verified: False
    OpenTimestamps Verified: False
    Effective Final Acceptance: False
    Maximum Timestamp Assurance: False

    This is the correct initial state. Stage377 must not claim successful dual-timestamp final acceptance until both independent external verification receipts satisfy every required condition.

    Stage377 Adds

    Production RFC3161 Verification

    The RFC3161 workflow creates a timestamp request for the fixed canonical Stage360 target.

    The returned timestamp response is checked with OpenSSL. Stage377 requires verification of the target message imprint, TSA signature, certificate chain, generation time, and fixed target SHA256.

    Raw TSQ, TSR, RFC3161 token, and certificate-bundle files remain outside the public docs directory. Only a metadata verification receipt may be published.

    Production OpenTimestamps Verification

    The OpenTimestamps workflow creates a proof for the same fixed Stage360 target.

    A newly created OpenTimestamps proof may remain pending while waiting for confirmation by a public blockchain anchor. Stage377 preserves that waiting state and does not convert it into a false success.

    The proof is not accepted as verified until its target hash, public anchor, anchor reference, and verified time satisfy the Stage377 policy.

    Stage377 Acceptance Conditions

    Requirement Mandatory condition
    Stage376 prerequisite Required Stage376 result and fixed hash are valid
    Historic Stage372 evidence Fixed Stage372 evidence hash remains unchanged
    RFC3161 target Message imprint matches the fixed Stage360 target
    RFC3161 signature TSA signature verification succeeds
    RFC3161 certificate TSA certificate-chain verification succeeds
    OpenTimestamps target Proof target matches the fixed Stage360 target
    OpenTimestamps anchor Public anchor and verified time are confirmed
    Common target Both receipts bind to the same Stage360 SHA256
    Verified proof count Two independent timestamp proofs are verified
    Publication boundary No raw proof or private material exists under docs

    Stage377 Decisions

    Decision Meaning
    timestamp_finalization_pending Neither external timestamp system has completed all final verification requirements.
    rfc3161_verified_opentimestamps_pending RFC3161 is verified, but OpenTimestamps remains pending.
    opentimestamps_verified_rfc3161_pending OpenTimestamps is verified, but RFC3161 remains pending.
    dual_timestamp_final_acceptance_verified Both independent proofs verified the same Stage360 target and the superseding effective final-acceptance state was established.
    block A prerequisite, required hash, proof, claim, consistency rule, or publication boundary failed.

    Historic Preservation

    Stage377 does not alter or overwrite Stage372 or Stage376. It preserves both earlier stages as historical evidence.

    Stage377 creates a later superseding operational state only after the stronger dual-timestamp requirements are satisfied. It does not rewrite an earlier final-acceptance record.

    Current Meaning

    Stage377 currently proves that the production dual-timestamp workflows, fixed hash bindings, Fail-Closed finalization engine, metadata receipt structures, and publication boundary have been prepared.

    The current initial result remains timestamp_finalization_pending.

    Stage377 therefore does not yet claim successful RFC3161 verification, successful OpenTimestamps verification, dual-timestamp final acceptance, or maximum timestamp assurance.

    After both independent systems verify the same fixed Stage360 target, Stage377 can establish the later superseding effective final-acceptance state.
