Abstract

Modern computing systems are generally designed to decide whether a user, application, device, service, workload, prompt, request, or process is authorized before computation begins. Once the computation is admitted and completes successfully, the resulting output is often treated as implicitly authorized to be transmitted, displayed, committed, signed, routed, stored, published, supplied to another system, used in a transaction, or converted into a physical or logical consequence.

This creates a distinct technical gap for artificial intelligence, autonomous agents, distributed systems, telecommunications, finance, robotics, industrial control, and other systems in which the actual output does not yet exist when the original request is authorized.

An authorized prompt does not necessarily authorize every generated response. An authorized AI-agent session does not necessarily authorize every tool call. An authorized financial computation does not necessarily authorize a particular transfer. An authorized communication request does not necessarily authorize the exact message ultimately transmitted. An authorized industrial-control process does not necessarily authorize the actuator command ultimately generated. A valid request may still produce an output that is modified, stale, misrouted, replayed, generated under compromised runtime state, based on poisoned retrieval or memory, outside the permitted purpose, or directed to an unauthorized destination.

This disclosure presents an execution-finality architecture that technically separates:

authority to initiate or perform computation, from
authority for the actual output produced by that computation to become externally effective.

The architecture treats a produced result as a Candidate Output and the prospective external consequence as a Candidate Act. Even after computation is complete, the Candidate Output is maintained in a Technically Non-Final State in which it lacks at least one effectuation-enabling resource required to create the intended external consequence. The actual produced output is canonicalized and identified through an output-specific digest, which forms part of a Candidate Act Descriptor. A Protected Enforcement Domain (PED) evaluates protected predicates including integrity, policy compliance, provenance, grounding, destination, jurisdiction, freshness, revocation, policy epoch, replay state, behavioral correspondence, quota, disclosure limits, runtime measurements, and other effectuation conditions.

When the required predicates are satisfied, the protected domain commits Protected Validation Evidence and conditionally releases a Scoped Non-Bearer Capability. The capability is not authoritative merely because it can be copied or possessed. Its use depends upon correspondence with protected state and with the exact Candidate Output, validation evidence, permitted effectuation scope, policy epoch, freshness state, and an identified Finality Sink or protected sink-selection rule.

The Finality Sink is defined by function rather than physical location. It is the protected role having mandatory control over a technically required effectuation dependency such as key release, signing, database commit, network transmission, storage admission, API invocation, user-interface release, telecommunications transmission, payment authorization, or actuator activation. Before effectuation, the Finality Sink may independently reconstruct a sink-local descriptor and verify correspondence between the output actually presented, local destination, interface, effect type, controller, route, policy state, capability, and protected validation evidence.

The architecture further addresses anti-bypass closure. It is not sufficient to place a policy check on one path while another operative interface, key, network route, driver, credential, storage namespace, queue, signing service, recovery interface, or privileged path can create the same external consequence. The architecture therefore places at least one required effectuation dependency under mandatory Finality Sink control and closes or equivalently governs alternative effectuation paths.

Where verification succeeds, capability-state consumption and effectuation may occur atomically or through a protected state machine. Where verification fails, the system fails closed: the Candidate Output remains technically non-final, the effectuation dependency is withheld, and the attempted consequence does not receive valid finality authority.

The central proposition is simple:

Computation is not authority.

A machine may compute, infer, generate, prepare, propose, sign, route, or formulate an act, but successful computation alone does not establish that the specific resulting act is authorized to become externally effective.

This architecture is intended as a technical enforcement layer rather than a post-hoc logging scheme. It can be implemented in hardware-rooted, software-isolated, cryptographic, transactional, distributed, or hybrid form and can be integrated into new or legacy systems through secure enclaves, trusted execution environments, hardware security modules, operating-system brokers, gateways, sidecars, service-mesh components, database controllers, network interfaces, payment-signing modules, telecommunications gateways, tool brokers, actuator controllers, or other protected effectuation points.

Core Technical Proposition

The architecture recognizes that successful computation and authorized external effectuation are different technical events.

A conventional system may ask:

Is this user, service, workload, prompt, request, or application allowed to perform this computation?

Execution-finality adds a second question:

Is the specific output that was actually produced, in the specific state in which it now exists, authorized to cross the technical effectuation boundary and create the specific external consequence now requested?

These two determinations are intentionally separated.

Why Request Authorization Alone Is Insufficient

Before computation, a system may know the requester, intended operation, input, expected workload, destination, or permitted scope. It may not yet know the exact bytes, tokens, fields, instructions, model-generated content, transaction values, tool parameters, actuator values, or other output elements that will actually be produced.

The produced output may:

differ from the expected output;
contain information not apparent from the original request;
incorporate unauthorized or poisoned data;
reflect compromised runtime behavior;
exceed an authorized purpose;
invoke a different tool;
target a substituted destination;
contain an unsafe command;
include an unintended transaction;
exceed a disclosure or consumption limit;
be generated under a stale policy epoch;
be modified between validation and release;
be replayed after prior use; or
reach an alternative effectuation path.

Accordingly, a valid request-side credential, access token, signed request, policy decision, or workload admission decision does not necessarily establish authority for the actual resulting output.

Why Post-Hoc Logging Is Not Enough

Logs, traces, audit records, provenance records, receipts, and security events can be useful for investigation and accountability. However, if evidence is produced only after a message has been transmitted, a transaction committed, a key released, a database modified, an actuator activated, or an AI output presented, the consequence may already be irreversible or practically difficult to undo.

This architecture therefore uses protected validation evidence as a precondition to effectuation, rather than relying only on evidence generated after effectuation.

Key Technical Terms

Candidate Output

A computational artifact produced by execution of a computation before the artifact has been authorized to become externally effective. It may be data, a message, a file, a command, a model output, a control signal, a transaction, an API response, a network packet, a database modification, software, a robotic action, an actuator instruction, multimedia content, or another computational result.

Candidate Act

The intended externally effective consequence associated with a Candidate Output.

Candidate Act Descriptor

A protected representation associated with the Candidate Output. It contains at least an output-specific digest and may also include workload identity, model or algorithm identity, destination, interface, effect type, tenant, purpose, jurisdiction, time, policy epoch, protected-state reference, provenance, grounding, runtime behavioral information, or other material effectuation attributes.

Output Digest

A deterministic identifier calculated over the Candidate Output or a deterministic representation of that output. It identifies what was actually produced, not merely what was originally requested.

Technically Non-Final State

A state in which the Candidate Output exists but cannot yet create the intended external effect because one or more technically necessary effectuation resources remain unavailable.

Protected Enforcement Domain (PED)

A protected execution environment that evaluates effectuation predicates, protects execution-finality state, commits protected validation evidence, and conditionally releases scoped finality authority. It may be implemented using hardware, firmware, trusted execution environments, secure enclaves, hardware security modules, cryptographic processors, operating-system security components, isolated execution environments, software isolation, or combinations thereof.

Protected Validation Evidence

Protected information generated after successful evaluation of required predicates. It may include authenticated measurements, signed records, secure receipts, cryptographic attestations, protected commitments, ledger commitments, protected state transitions, or combinations thereof.

Scoped Non-Bearer Capability

A capability whose authority does not arise from possession alone. Its valid use depends on correspondence with protected information such as the Candidate Output, output digest, Candidate Act Descriptor, protected validation evidence, Finality Sink, permitted effectuation scope, policy epoch, runtime state, freshness information, and anti-replay state.

Permitted Effectuation Scope

The bounded scope within which the Candidate Output may become effective. The scope may specify destination, recipient, interface, jurisdiction, time window, quota, action type, network, tenant, device, external system, security domain, or use limit.

Finality Sink

The protected enforcement role that has mandatory control over at least one technical operation or resource without which the Candidate Output cannot obtain the intended usable external effect. The Finality Sink is function-defined and location-neutral.

Technical Effectuation Boundary

The boundary at which the Candidate Output first becomes externally observable, usable, irreversible, persistent, operationally significant, legally significant, financially significant, or physically consequential.

Finality Sink: Functional and Location-Neutral

A Finality Sink is not restricted to a physical downstream gateway. Depending on the system, it may be:

a key-release controller;
a signing controller;
a database transaction engine;
a storage controller;
an operating-system broker;
a hypervisor;
a secure enclave;
a hardware security module;
a network interface;
a telecommunications controller;
a payment-signing module;
a user-interface release mechanism;
a tool-call broker;
an API gateway;
a message broker;
a device driver;
an actuator controller;
a cloud sidecar;
a service-mesh component;
a kernel-level enforcement point; or
another component controlling a technically necessary effectuation operation.

Validation and effectuation may occur in separate protected components or in one protected component, provided that the output cannot become externally effective until the required output-specific finality conditions have been satisfied.

Anti-Bypass Closure

A validator is insufficient if an equivalent external effect can be created through another operative path.

Alternative paths may include:

direct application-programming interfaces;
administrative or maintenance interfaces;
recovery or diagnostic interfaces;
unmediated network connections;
fallback routes;
direct device-driver access;
independent signing services;
alternate database credentials;
separate storage namespaces;
replicated queues;
unprotected tool connectors;
copied output channels;
privileged software paths; or
other routes capable of creating the same external consequence.

The architecture therefore identifies at least one required effectuation dependency and places that dependency under mandatory or non-bypassable Finality Sink control. Alternative paths are closed, disabled, isolated, cryptographically constrained, or brought under equivalent finality enforcement.

Possible mechanisms include exclusive key custody, mandatory operating-system or kernel mediation, hypervisor mediation, hardware isolation, service-mesh enforcement, secure boot, device binding, mandatory access control, driver-level mediation, protected routing, cryptographic sealing, namespace restrictions, capability-controlled invocation, destination-side verification, protected transaction control, and removal of alternate credentials.

Output-Specific Verification

A central technical distinction is that the architecture binds finality authority to the output actually produced.

The Finality Sink may independently reconstruct a local descriptor from locally observed information including:

local_output_digest
local_sink_id
local_destination_id
local_interface_id
local_effect_type
local_controller_id
local_device_id
local_key_id
local_route_id
local_policy_epoch
local_topology_measurement
local_protected_state_reference

The sink-local descriptor can be compared with the Candidate Act Descriptor, validation evidence, and capability. Any material mismatch can cause denial.

This helps prevent an intermediate component from obtaining authorization for one output, destination, route, controller, or policy state and using that authority for another.

Atomic Consumption and Effectuation

Successful finality may be coupled to protected state consumption so that a one-time or bounded capability cannot simply be copied and reused.

Depending on the implementation, atomic or protected coupling may use:

database transactions;
compare-and-swap operations;
hardware monotonic counters;
transactional memory;
write-ahead logs;
two-phase commit;
protected state machines;
enclave-sealed state;
idempotency records;
consensus protocols;
atomic message-queue acknowledgement;
cryptographic one-time keys; or
single-use capability registers.

Where complete cross-system atomicity is unavailable, a protected state progression may be used, for example:

ISSUED → PRESENTED → RESERVED → EFFECTUATED → CONSUMED

or:

ISSUED → PRESENTED → DENIED → INVALIDATED

The objective is to prevent replay, duplicate effectuation, concurrent double use, stale re-use, or effectuation without corresponding protected-state progression.

Artificial Intelligence and Agentic AI

AI systems increasingly generate outputs that are not passive text. They can generate:

tool calls;
API invocations;
database queries;
software code;
financial instructions;
communications;
access requests;
procurement actions;
robotic commands;
operational plans;
configuration changes;
data disclosures; and
multi-step autonomous workflows.

They may also depend on memory, retrieval systems, external tools, plugins, other models, and changing runtime state.

The architecture therefore does not assume that authorization of the prompt, user session, model invocation, or agent process automatically authorizes every output.

For AI output, the system may buffer the generated response, canonicalize it, compute an output-specific digest, form a Candidate Act Descriptor, and evaluate predicates such as:

model integrity;
runtime integrity;
model or algorithm identity;
output-policy compliance;
grounding;
provenance;
behavioral conformity;
confidentiality;
destination authorization;
disclosure budget;
session validity;
policy epoch;
revocation; and
replay state.

A model-output gateway, tool broker, user-interface controller, API gateway, downstream-agent gateway, or another protected boundary can operate as the Finality Sink.

For agentic AI, each proposed tool action may be treated as a separate Candidate Act. Authority may be scoped to tool identity, API method, destination, amount, parameter range, use count, completion deadline, or another bounded action property.

The agent therefore does not obtain external authority merely because it can generate the tool call.

Streaming Outputs

For streaming systems, output-specific finality may operate per chunk, bounded group of chunks, rolling commitment, Merkle commitment, or complete stream.

A later chunk can be denied even when earlier chunks passed. The Finality Sink may stop release when a rolling protected predicate ceases to be satisfied.

Split-Trust and Legacy Deployment

The architecture can separate the computation trust domain from the effectuation trust domain. A first domain may generate a sealed Candidate Output while a second domain independently verifies the output digest, capability, evidence, destination, and scope before allowing release.

It can also be deployed around legacy applications without retraining or materially changing their computational logic. A shim, proxy, sidecar, gateway, operating-system broker, or service-mesh component can intercept the output before external effectuation and impose mandatory output-finality mediation.

Technical Effects

The architecture may provide one or more of the following technical effects:

preventing request authorization from automatically authorizing a produced output;
binding effectuation authority to the exact Candidate Output;
preventing reuse of a capability with a modified output;
preventing use at an unauthorized Finality Sink;
preventing release outside a permitted effectuation scope;
keeping a Candidate Output technically non-final after computation completes;
reducing replay, substitution, routing, and time-of-check/time-of-use attacks;
permitting revocation after capability issuance but before effectuation;
enabling output-specific enforcement without modifying the underlying model or application;
providing deterministic denial at a mandatory technical boundary;
generating protected evidence showing why an output was permitted or denied;
coupling capability consumption to external effectuation;
preventing the execution substrate from unilaterally conferring external authority on its own output;
allowing separate trust domains for computation and effectuation; and
supporting hardware-rooted, software-isolated, distributed, transactional, cryptographic, or hybrid enforcement.

Industrial Applicability

The architecture is applicable to systems in which computational outputs may create informational, operational, financial, legal, physical, security, or other external consequences, including:

artificial intelligence and autonomous agents;
cloud computing;
telecommunications;
cybersecurity;
financial services;
industrial automation;
robotics;
autonomous vehicles;
healthcare information systems;
digital identity;
electronic commerce;
government systems;
defense systems;
storage and database infrastructure;
software-as-a-service platforms;
content-delivery systems;
critical infrastructure; and
Internet-of-Things systems.

It may be integrated into processors, servers, gateways, routers, mobile devices, embedded devices, cloud platforms, telecommunications networks, operating systems, application frameworks, AI platforms, industrial controllers, and secure hardware.

Relationship to the Broader Technical Family

The source disclosure identifies International Application No. PCT/IB2026/055615, filed June 4, 2026, as the “Mothership Application” / “DAS Protocols Mothership.” It describes the broader architecture as separating computation from authority to produce an externally effective consequence through protected authorization states, mandatory enforcement operations, protected validation evidence, scoped finality authority, protected-state transitions, and Finality Sink verification.

The present technical disclosure focuses particularly on output-bound execution finality: an output is produced, kept technically non-final, identified through an output-specific digest, subjected to protected validation, bound to scoped non-bearer finality authority, and independently verified at a Finality Sink controlling a required effectuation dependency.

Frequently Asked Questions (FAQ)

1. What is the execution-finality architecture in simple terms?

It is a technical architecture that separates computing an output from authorizing that output to create an external consequence.

A system may be allowed to calculate, infer, generate, prepare, or propose something, but the resulting output is not automatically allowed to be transmitted, published, committed, signed, stored, paid, routed, or used to control a physical device.

The core principle is:

Computation is not authority.

2. Why is this needed if the original request was already authorized?

Because the exact output may not exist when the original request is approved.

A user may be authorized to ask an AI system to perform a task, but the system may later generate an output that:

exceeds the intended purpose;
contains unauthorized information;
invokes the wrong tool;
targets the wrong destination;
reflects stale policy;
was influenced by poisoned memory or retrieval;
has been modified after generation; or
creates a consequence that was never authorized.

Request authorization and output-effectuation authorization are therefore technically different decisions.

3. What is a Candidate Output?

A Candidate Output is the actual computational result that has been produced but has not yet been authorized to become externally effective.

Examples include:

an AI-generated response;
a payment instruction;
a database update;
an API call;
a network message;
a tool invocation;
a robot command;
an actuator instruction;
a file;
a signed object;
a configuration change.

The output exists, but it is still held in a controlled state.

4. What is a Candidate Act?

A Candidate Act is the external consequence that would occur if the Candidate Output were allowed to take effect.

For example:

sending a message;
publishing an AI response;
committing a database transaction;
transferring money;
invoking an external API;
activating a robot;
changing a network configuration;
releasing a file;
signing a transaction.

The Candidate Output is the produced artifact. The Candidate Act is the consequence that artifact would create.

5. What does “Technically Non-Final State” mean?

It means the output has been generated but still lacks at least one technically necessary condition for external effectuation.

The output may be:

sealed;
encrypted;
unsigned;
unrouted;
uncommitted;
held in a protected buffer;
unavailable to a user interface;
blocked from a network interface;
blocked from a database commit;
blocked from an actuator.

This is more than a warning label. The system is technically prevented from completing the consequence until finality verification succeeds.

6. What is the difference between a request digest and an output digest?

A request digest identifies what was requested before execution.

An output digest identifies what was actually produced after execution.

This distinction is important because the final output may differ from the original request.

The architecture therefore uses an output-specific digest or equivalent deterministic representation so that finality authority can be bound to the real Candidate Output rather than merely to an earlier request.

7. What is a Candidate Act Descriptor?

A Candidate Act Descriptor is a protected representation of the Candidate Output and the proposed consequence.

It may include:

output digest;
model or workload identity;
destination;
recipient;
interface;
purpose;
jurisdiction;
effect type;
policy epoch;
runtime measurements;
provenance;
grounding references;
protected-state references;
time or freshness information.

It gives the protected enforcement process a structured description of what is actually about to become effective.

8. What is a Protected Enforcement Domain?

A Protected Enforcement Domain (PED) is the environment in which required finality conditions are evaluated and protected authorization state is maintained.

It may be implemented using:

a trusted execution environment;
secure enclave;
hardware security module;
secure processor;
isolated operating-system component;
protected software environment;
firmware;
cryptographic processor;
or a combination of hardware and software protections.

Its purpose is to prevent ordinary application code from simply changing the finality decision.

9. What does the Protected Enforcement Domain actually check?

Depending on the use case, it may evaluate conditions such as:

output integrity;
model or runtime integrity;
approved purpose;
authorized destination;
authorized recipient;
policy compliance;
provenance;
grounding;
jurisdiction;
freshness;
revocation status;
quota;
disclosure budget;
policy epoch;
anti-replay state;
prior consumption;
behavioral limits;
security context.

Not every implementation needs every predicate.

10. What is Protected Validation Evidence?

Protected Validation Evidence is evidence created by the protected validation process showing that the required conditions were satisfied.

It may be represented as:

a signed record;
cryptographic commitment;
authenticated measurement;
secure receipt;
attestation;
protected state transition;
ledger commitment;
or another protected representation.

The important point is timing: the evidence is committed before or atomically with release of finality authority, not merely after the external consequence has already occurred.

11. What is a Scoped Non-Bearer Capability?

It is a narrowly bounded execution-finality authority that cannot be used merely because someone possesses or copies it.

Its valid use depends on protected correspondence with things such as:

the exact Candidate Output;
output digest;
protected validation evidence;
permitted destination;
Finality Sink;
policy epoch;
freshness state;
anti-replay state;
protected local state;
permitted effectuation scope.

Possession alone is therefore insufficient.

12. Why is “non-bearer” important?

A conventional bearer token may effectively mean:

“Whoever possesses this token can use it.”

That can create problems if malware copies, forwards, exports, or replays the token.

A non-bearer capability is different. Its authority depends on protected context and state, so copying the capability alone does not necessarily reproduce the authority to use it.

13. What is a Finality Sink?

A Finality Sink is the protected point that controls a technically necessary operation required for the Candidate Output to become externally effective.

It might control:

release of a cryptographic key;
generation of a signature;
a database commit;
network transmission;
a payment instruction;
persistent storage;
release to a user interface;
an API call;
a telecommunications message;
a robot or actuator command.

The Finality Sink is defined by its control function, not by where it physically sits in the system.

14. Does the Finality Sink have to be a separate hardware device?

No.

The Finality Sink may be:

separate from the Protected Enforcement Domain;
inside the same secure component;
implemented in software;
implemented in hardware;
distributed across multiple components;
implemented by an operating-system broker;
implemented by a gateway;
implemented by a transaction engine;
implemented by a secure enclave.

What matters is that the Candidate Output cannot obtain the intended external effect without passing the required finality verification.

15. What does “location-neutral Finality Sink” mean?

It means the Finality Sink is not defined as “the downstream gateway” or “the last device in the chain.”

It can be the first protected point whose successful operation makes the external effect technically usable.

For one system that may be a key-release function. For another it may be a database commit engine, network interface, signing controller, tool broker, user-interface release mechanism, or actuator controller.

The role is defined by technical control over effectuation.

16. What is anti-bypass closure?

Anti-bypass closure means the architecture does not protect only one obvious path while leaving another path capable of creating the same external consequence.

For example, blocking one API is not enough if the same action can still occur through:

another API;
an administrator interface;
a fallback route;
a diagnostic interface;
a copied credential;
a direct driver call;
an alternate signing service;
another storage namespace;
a separate queue;
an unmediated network path.

The system therefore identifies a required effectuation dependency and ensures that equivalent alternative paths are closed or brought under equivalent finality control.

17. Is this just another access-control system?

No.

Traditional access control usually asks whether a user, service, application, or workload is permitted to access a resource or start an operation.

Execution finality focuses on a later question:

Is the exact output that was actually produced authorized to cause the exact external consequence now requested?

It therefore adds output-specific, effectuation-time control after or alongside request-side authorization.

18. Is this the same as OAuth, API keys, or capability security?

No.

OAuth, API keys, roles, permissions, and capability systems remain useful for request-side access and delegation.

Execution finality addresses a different problem: whether the specific produced output should be allowed to cross the consequence boundary.

These systems can be used together. Request authorization can determine who may compute, while execution finality determines whether the actual result may become effective.

19. Is this just logging, audit, or provenance?

No.

Logging and provenance mainly help explain what happened.

Execution finality is intended to help determine whether the consequence is allowed to happen before it happens.

A post-hoc log may show that an unauthorized transfer occurred. A finality mechanism is intended to prevent the transfer from receiving valid effectuation authority in the first place.

20. Is blockchain required?

No.

A ledger may be used for some forms of protected validation evidence, state commitment, audit, or coordination, but blockchain is not a requirement.

The architecture may be implemented using:

secure hardware;
protected software;
local trusted state;
cryptographic attestations;
transactional databases;
secure enclaves;
HSMs;
monotonic counters;
operating-system mediation;
distributed trust;
or hybrid approaches.

21. Does this require zero-knowledge proofs?

No.

Zero-knowledge proofs may be used in some implementations, but they are not required.

The baseline architecture only requires that the necessary predicates, evidence, state, and effectuation authority be protected sufficiently for the deployment's threat model.

22. How does this apply to AI agents?

An AI agent may generate many proposed actions:

send an email;
make a payment;
call an API;
modify a database;
purchase an item;
change a configuration;
command a robot;
invoke another agent.

Each proposed action can be represented as a Candidate Act.

The agent may generate the action, but generation alone does not provide final authority to execute it.

A tool broker, API gateway, operating-system broker, payment controller, network gateway, or other effectuation point can verify bounded authority before the action becomes effective.

23. Does this require retraining the AI model?

Not necessarily.

The architecture can operate outside the model.

A model can produce an output normally, while a separate output-holding, validation, and finality layer controls whether the output is released.

This allows execution-finality enforcement to be added around existing models and applications without necessarily changing model weights or retraining the model.

24. Can legacy systems use this architecture?

Potentially, yes.

A legacy application may be surrounded by:

a proxy;
sidecar;
gateway;
operating-system broker;
service-mesh component;
network egress controller;
database commit controller;
or another mediation point.

The output can be intercepted before external effectuation and held until protected finality validation succeeds.

Complete coverage still requires that relevant alternate consequence paths are also controlled.

25. Would this make AI systems too slow?

Not necessarily.

Complex policy formation can occur before the final effectuation step, while the Finality Sink performs a smaller set of protected checks at release time.

For latency-sensitive systems, implementations can use:

local protected state;
precomputed authorization state;
compact capabilities;
hardware-assisted verification;
cached policy state;
monotonic counters;
fast cryptographic verification;
split slow/fast authorization paths.

The architecture does not require a remote human approval or cloud round trip for every effectuation.

26. What happens if conditions change after validation?

The Finality Sink can verify current protected state immediately before effectuation.

Examples of changed conditions include:

capability revocation;
policy-epoch change;
destination change;
route change;
quota exhaustion;
output modification;
jurisdiction change;
loss of trusted runtime state;
prior capability consumption.

A previously valid decision therefore does not have to remain valid forever.

27. How does the architecture prevent replay or double use?

A capability can be bound to protected anti-replay state such as:

nonce;
monotonic counter;
use count;
consumption flag;
transaction state;
invocation identifier;
expiry;
protected sequence state.

The Finality Sink verifies the current state and may atomically reserve, consume, or invalidate the capability when effectuation occurs.

This makes copied or previously used authority insufficient for repeated effectuation.

28. What does “atomic consume-and-effectuate” mean?

It means capability use and the external consequence are coupled through one protected transaction or protected state machine.

For example:

a database commit and capability consumption may occur together;
a signing key may sign only while consuming the associated capability;
a network send may reserve and finalize one-time state;
an actuator controller may consume authority when executing the validated command.

The goal is to avoid a gap where authority is consumed without effectuation, or effectuation occurs without corresponding protected-state consumption.

29. What happens when verification fails?

The architecture is designed to fail closed.

Depending on the implementation, the system may:

deny effectuation;
keep the Candidate Output sealed or buffered;
invalidate or consume the capability as denied;
quarantine the output;
request revalidation;
generate a protected denial record;
revoke related authority;
isolate the execution substrate;
escalate for review.

The key property is that failure does not silently convert into permission.

30. What is the main technical difference from conventional computing?

Conventional systems commonly treat successful request authorization and successful computation as sufficient for downstream release.

Execution finality adds a protected output-specific boundary:

Conventional pattern:
Request authorized
→ computation executes
→ output released

Execution-finality pattern:
Request authorized
→ computation executes
→ Candidate Output held non-final
→ output-specific digest
→ protected validation
→ protected validation evidence
→ scoped non-bearer capability
→ Finality Sink verification
→ protected consumption
→ external effect

The central difference is therefore not merely stronger authentication or more logging.

It is the technical separation of:

authority to compute

from

authority for the exact produced output to become externally effective.

Relationship to the Mothership Application / PCT/IB2026055615 International Application No. PCT/IB2026/055615, filed June 4, 2026, is referred to in the present disclosure as the “Mothership Application,” “DAS Protocols Mothership,” or “Mothership.” The Mothership Application discloses a broader execution-finality architecture in which computation is separated from authority to produce an externally effective consequence through one or more protected authorization states, mandatory enforcement operations, protected validation evidence, scoped finality authority, protected-state transitions, and verification at a Finality Sink. The present disclosure is technically connected to and develops focused implementations within that broader architecture. More particularly, the present disclosure develops embodiments in which: 1. a proposed computation is subjected to a pre-computation protected determination; 2. scoped execution authority permits initiation or performance of the computation without conferring authority over an output subsequently produced by the computation; 3. the computation produces a Candidate Output maintained in a technically non-final state; 4. the execution substrate lacks independent access to at least one effectuation-enabling resource required to render the Candidate Output externally effective; 5. an output-specific digest is computed over the Candidate Output or a deterministic representation thereof after the Candidate Output has been produced; 6. output-specific protected validation evidence is committed after production of the Candidate Output; 7. scoped non-bearer finality authority is bound to the produced Candidate Output, protected validation evidence, a permitted effectuation scope, and a Finality Sink or protected sink- selection rule; 8. the Finality Sink is defined according to mandatory control over an effectuation-enabling resource rather than by physical location or component label; 9. the Finality Sink independently verifies correspondence to the actual Candidate Output before external effectuation; 10. the architecture prevents external effectuation through an operative alternative path lacking equivalent output-specific finality verification; and 11. protected-state consumption or advancement is coupled to exercise or release of the effectuation-enabling resource.Accordingly, the present disclosure may be implemented as a focused execution-finality embodiment, subsystem, deployment profile, industry-specific implementation, improvement, extension, or complementary architecture within the broader technical framework disclosed in the Mothership Application. The relationship to the Mothership Application does not require every embodiment of the present disclosure to contain every component, term, sequence, or implementation described in the Mothership Application. The present disclosure expressly supports, among other embodiments: • a combined pre-computation and post-computation architecture; • a pre-computation gate that structurally reserves output finality for a later output-specific determination; • a stand-alone post-computation output-finality architecture; • a single protected enforcement point performing validation and effectuation; • physically separated validation and Finality Sink components; • a location-neutral Finality Sink; • artificial-intelligence-specific execution-finality enforcement; • distributed, hardware-rooted, software-isolated, transactional, cryptographic, or hybrid implementations.

BACKGROUND OF THE INVENTION Field of the Invention The present disclosure relates generally to computer security, execution governance, trusted computing, artificial-intelligence governance, authorization systems, distributed computing, and control of externally consequential computational operations. More particularly, the disclosure relates to architectures and methods for separately controlling:1. 2. authorization to initiate or perform a computation; and authorization for a particular output produced by the computation to become externally effective. The disclosed subject matter further relates to maintaining a produced computational output in a technically non-final state, generating output-specific protected validation evidence after the output has been produced, establishing scoped finality authority bound to the produced output, and verifying the finality authority at a location-neutral Finality Sink having mandatory control over an effectuation-enabling resource required for external effectuation. The disclosure is applicable, without limitation, to artificial-intelligence systems, autonomous agents, cloud platforms, telecommunications systems, financial systems, storage systems, database systems, industrial controllers, cyber-physical systems, robotic systems, application-programming- interface infrastructures, operating systems, distributed computing environments, and other systems in which computational outputs may cause external consequences. Background Modern computing systems routinely determine whether a user, application, device, workload, service, or execution environment is authorized to request or perform an operation. Such authorization may be based on, for example: • user identity; • service identity; • credentials; • roles; • permissions; • access-control policies; • request attributes; • workload measurements; • trusted-execution-environment attestations; • device state; • application identity; • cryptographic tokens; • signed requests; • policy-engine decisions; • contextual information; • network location; • resource entitlements; • risk scores. In many systems, authorization is evaluated before a computation begins or before a requested operation is admitted into an execution environment. Once the request has been authorized and the computation has executed, the resulting output may be transmitted, displayed, committed, signed, routed, stored, published, supplied to another system, or used to control a physical or logical process. Such architectures may treat successful authorization of the request or successful execution of the computation as sufficient authority for the resulting output. This treatment may create a technical gap.A request describes an intended computation or operation before execution. The output produced by the computation does not necessarily exist at the time the request is authorized. Consequently, request-side information may not identify the exact output that will later be produced. A computational process may produce an output that: • differs from an expected output; • contains information not apparent from the original request; • reflects compromised runtime behavior; • incorporates unauthorized data; • exceeds an authorized purpose; • invokes a different tool or destination; • contains an unsafe command; • includes an unintended transaction; • exceeds a disclosure or consumption limit; • is generated under stale policy; • is produced after a protected condition has changed; • is redirected to an unauthorized interface; • is modified between validation and release; • is replayed after prior use; • is presented through an alternate effectuation path. Thus, authorization to initiate a computation and authorization to effectuate the actual result of the computation are technically different determinations. Request Authorization Does Not Necessarily Identify the Produced Output Before a computation executes, a system may identify: • the requesting entity; • the requested operation; • the proposed execution environment; • the expected workload; • the requested input; • the intended destination; • an anticipated action; • a permitted scope. However, the system may not yet possess the particular bytes, tokens, records, instructions, transaction fields, model-generated content, tool parameters, actuator values, or other output elements that will be produced during execution. A digest or commitment generated before computation may identify the request or an anticipated operation. Such a digest does not necessarily identify the exact output ultimately produced. Where a computational process is probabilistic, adaptive, state-dependent, distributed, externally informed, or influenced by retrieved data or tool responses, different outputs may be produced from similar or identical requests. Even a deterministic computation may produce different outputs when: • execution state changes; • dependencies change; • memory state changes; • external data changes;• model weights or runtime components change; • an execution environment is compromised; • a destination or effectuation context changes. Accordingly, a request-side authorization artifact may be valid for a request while being insufficient to establish that a subsequently produced output is permitted to become externally effective. Limitations of Single-Stage Authorization A single authorization decision may combine or conflate: 1. permission to perform a computation; and 2. permission to release or effectuate any result produced by that computation. This conflation may be especially problematic in artificial-intelligence and autonomous-agent systems. For example, authorization of a prompt or model invocation does not necessarily establish that every generated response, tool call, transaction proposal, executable instruction, or agent action is authorized. Similarly: • authorization to execute a financial computation does not necessarily authorize a particular resulting transfer; • authorization to process a communication request does not necessarily authorize the resulting transmission; • authorization to run an industrial-control algorithm does not necessarily authorize a resulting actuator command; • authorization to generate a database update does not necessarily authorize commitment of the resulting modification; • authorization to process protected data does not necessarily authorize release of every inference derived from the data; • authorization to execute software does not necessarily authorize every externally consequential output generated by the software. A need therefore exists for a technical separation between computation authority and effectuation authority. Post-Hoc Logging Is Insufficient Some systems generate audit logs, receipts, traces, provenance records, or security events after an output has already been released or an operation has already taken effect. Such records may assist investigation, compliance, or attribution. However, post-hoc evidence does not necessarily prevent the external effect from occurring. Once a transaction has been committed, a message transmitted, a key released, an actuator activated, a record disclosed, or an output presented, later detection may not reverse the consequence. A need therefore exists for protected validation evidence that is committed as a technical precondition to external effectuation rather than being generated only after completion of the external effect. Policy Decisions Without Technical Non-CompletabilityA system may determine that an output should not be released but nevertheless leave the execution substrate technically capable of releasing the output through another interface, credential, key, service, route, controller, or privileged operation. In such a system, denial may be administrative or policy-based rather than technically enforced. For example, the execution substrate may retain access to: • an output-encryption key; • a signing key; • a transaction-commit interface; • a database credential; • a network socket; • a routing function; • a tool credential; • a storage namespace; • a user-interface channel; • an actuator driver; • an application-programming-interface credential. If the execution substrate retains independent control over the resource that produces the external effect, compromise or redirection of the execution substrate may permit bypass of an intended policy decision. A need therefore exists for an architecture in which the execution substrate lacks independent access to at least one technically necessary effectuation-enabling resource. Bypass Through Alternate Effectuation Paths An intended enforcement point may be bypassed when the same external consequence can be produced through another path. Alternative paths may include: • a direct application-programming interface; • an administrative interface; • a maintenance interface; • a recovery interface; • an unmediated network connection; • a fallback route; • a diagnostic port; • a separate database credential; • a replicated queue; • a direct device-driver interface; • a secondary storage namespace; • an alternate signing service; • a copied output channel; • an unprotected tool connector; • a privileged execution path. Merely placing a validator or gateway in one communication path does not ensure non- bypassability if another operative path can produce the same usable external effect.A need therefore exists for enforcement that controls a technically required effectuation dependency and that prevents successful external effectuation through operative alternate paths lacking equivalent output-specific verification. Limitations of Location-Specific Enforcement Models Execution governance is sometimes described in terms of a particular gateway, downstream server, network boundary, or physically separate trusted component. However, the first technically controlling point at which an output can become usable may vary by implementation. For example, the relevant point may be: • a key-release function; • a signing function; • a database transaction engine; • a storage controller; • an operating-system broker; • a hypervisor; • a secure enclave; • a hardware security module; • a network interface; • a telecommunications controller; • a user-interface release mechanism; • a tool-call broker; • an actuator controller. In some implementations, validation and effectuation may be performed by physically separate components. In other implementations, they may occur within a single protected component while remaining logically distinct operations. A need therefore exists for a location-neutral definition of the final enforcement role based on mandatory technical control over effectuation rather than physical placement or component label. Time-of-Check and Time-of-Use Risks Even where a request or output has been validated, conditions may change before external effectuation. For example: • a policy epoch may change; • a capability may be revoked; • a destination may change; • a route may change; • an output may be modified; • a capability may be replayed; • a use limit may be exhausted; • an execution environment may lose its trusted state; • a jurisdictional condition may change; • a protected state transition may already have occurred. If validation and effectuation are not coupled through protected state, a previously valid decision may be reused under changed circumstances.A need therefore exists for output-specific finality authority that is checked against freshness, protected state, policy epoch, revocation, consumption, and anti-replay conditions immediately before effectuation. Artificial-Intelligence and Agentic-System Risks Artificial-intelligence systems increasingly generate outputs that are not limited to passive text. A model or agent may generate: • database queries; • software code; • system commands; • financial instructions; • communications; • access requests; • procurement actions; • tool calls; • robotic commands; • operational plans; • API invocations; • configuration changes; • data disclosures. The artificial-intelligence system may also interact with retrieval systems, memory stores, external tools, plugins, autonomous workflows, and other models. Authorization of a prompt or model invocation does not necessarily establish that the exact generated output is safe, grounded, permitted, correctly scoped, or suitable for the intended destination. Further, an artificial-intelligence model or agent may be manipulated through: • prompt injection; • memory poisoning; • retrieval poisoning; • malicious tool output; • compromised context; • unauthorized model substitution; • runtime modification; • policy evasion; • destination substitution; • multi-step action decomposition. A need therefore exists for technical enforcement applied to the produced artificial-intelligence output after generation and before the output is released or permitted to cause an external effect. Need for Separate Execution and Finality Authorities Accordingly, there remains a need for systems that: • authorize computation through a first protected stage; • expressly limit the first-stage authority to computation initiation or performance; • maintain the produced output in a technically non-final state; • independently identify the output actually produced;• perform protected validation after output production; • commit output-specific protected validation evidence; • establish separate output-specific finality authority; • bind finality authority to the exact output, protected evidence, effectuation scope, and Finality Sink; • isolate a technically required effectuation-enabling resource from the execution substrate; • verify finality conditions immediately before external effectuation; • consume or update protected state in association with effectuation; • prevent bypass through alternative effectuation paths; • fail closed when any required condition cannot be verified. The present disclosure addresses these and other technical needs. DEFINITIONS Candidate Output A Candidate Output is a computational artifact produced by execution of a computation before the artifact has been authorized to become externally effective. The Candidate Output may comprise data, messages, files, commands, model outputs, control signals, transactions, API responses, network packets, database modifications, software objects, machine instructions, robotic actions, actuator instructions, multimedia content, or any other computational result. A Candidate Output does not necessarily imply authorization for external use. Candidate Act A Candidate Act is the intended externally effective consequence associated with a Candidate Output. The Candidate Act represents the prospective externally usable action that would occur if execution finality is successfully completed. Candidate Act Descriptor A Candidate Act Descriptor is a protected representation associated with a Candidate Output. The Candidate Act Descriptor comprises at least an output digest identifying the produced Candidate Output and may further comprise identifiers, metadata, execution measurements, policy identifiers, timestamps, version identifiers, workload identifiers, destination identifiers, context descriptors, or other information required for execution-finality verification.The Candidate Act Descriptor identifies the produced output itself rather than merely identifying an operation request. Output Digest An Output Digest is a deterministic identifier computed over the Candidate Output or over a deterministic representation thereof. The digest uniquely identifies the produced computational artifact for purposes of execution-finality verification. The digest is output-derived rather than request-derived. Technically Non-Final State A Technically Non-Final State is a computational state in which a Candidate Output exists but cannot become externally effective because one or more technical mechanisms necessary for external effectuation remain unavailable. The technically non-final state is maintained independently of authorization to initiate computation. Protected Enforcement Domain A Protected Enforcement Domain (PED) is an execution environment configured to evaluate protected predicates, generate protected validation evidence, release scoped non-bearer capabilities, and protect execution-finality state against unauthorized modification. The Protected Enforcement Domain may comprise hardware, software, firmware, trusted execution environments, secure enclaves, hardware security modules, cryptographic processors, isolated execution environments, operating-system security components, or combinations thereof. Protected Predicate A Protected Predicate is a condition required to be satisfied before a Candidate Output becomes externally effective. Protected predicates may evaluate integrity, policy compliance, behavioral correspondence, authorization state, freshness, provenance, grounding, jurisdiction, destination, execution measurements, revocation status, replay status, policy epoch, or any other execution-finality requirement. Protected Validation Evidence Protected Validation Evidence comprises protected information generated after successful evaluation of protected predicates demonstrating that execution-finality requirements have been satisfied.Protected validation evidence may comprise signed records, protected commitments, authenticated measurements, cryptographic attestations, ledger commitments, secure receipts, protected state transitions, or combinations thereof. Scoped Non-Bearer Capability A Scoped Non-Bearer Capability is a capability released only after successful validation and whose authority depends upon successful verification of bound protected information rather than mere possession. The scoped non-bearer capability is bound to one or more of: • Candidate Output • Candidate Act Descriptor • Output Digest • Protected Validation Evidence • Finality Sink • Permitted Effectuation Scope • Policy Epoch • Runtime State • Freshness Information • Anti-Replay Information Possession of the capability alone is insufficient to authorize external effectuation. Finality Sink ( Detailed defination later ) A Finality Sink is a technical enforcement component positioned at, or exercising non-bypassable control over, an execution-effectuation boundary. The Finality Sink independently verifies whether execution-finality requirements have been satisfied before permitting a Candidate Output to become externally effective. The Finality Sink represents the mandatory technical point through which external effectuation is authorized. Technical Effectuation Boundary A Technical Effectuation Boundary is the system boundary at which a Candidate Output first becomes capable of producing externally observable, externally usable, irreversible, or externally consequential effects. Permitted Effectuation Scope A Permitted Effectuation Scope defines the authorized limits under which a Candidate Output may become externally effective. The permitted scope may specify one or more of: • destination• interface • recipient • jurisdiction • time window • quota • action type • network • tenant • device • security domain • external system • consumption limits Externally Effective A Candidate Output becomes Externally Effective when it produces an observable consequence outside the protected execution-finality architecture. External effectuation includes, without limitation: • transmitting information, • releasing AI outputs, • modifying external databases, • actuating devices, • controlling robots, • issuing financial transactions, • emitting telecommunications messages, • granting access, • modifying persistent storage, • invoking downstream services, • producing legally or operationally significant consequences. Consumption Consumption of a scoped non-bearer capability comprises irreversible use of that capability for successful execution finality, after which reuse is denied according to the execution-finality policy. Policy Epoch A Policy Epoch identifies a version of execution-finality policy governing protected predicate evaluation. Changes in Policy Epoch may invalidate previously released capabilities. Anti-Replay Information Anti-Replay Information comprises protected state preventing repeated use of a previously consumed scoped non-bearer capability.SYSTEM OVERVIEW The disclosed architecture establishes a technical separation between: 1. authorization to receive or execute a computational request; and 2. authorization to permit the resulting computational output to become externally effective. Execution of a computation does not itself confer authority upon the resulting output. A computational result may therefore exist as a Candidate Output while remaining in a technically non-final state. The Candidate Output cannot produce an authorized external consequence until output-specific protected validation has been completed and a Finality Sink has independently verified the resulting protected authority. In one embodiment, the architecture comprises: (a) an execution substrate configured to receive an operation request and execute a computation; (b) an output-holding or output-sealing mechanism configured to maintain the resulting Candidate Output in a technically non-final state; (c) a Candidate Act Descriptor generator configured to produce an output-specific representation of the Candidate Output; (d) a Protected Enforcement Domain configured to evaluate protected predicates, commit protected validation evidence, and conditionally release a scoped non-bearer capability; (e) a protected-state repository configured to maintain freshness, consumption, revocation, policy- epoch, and anti-replay state; and (f) a Finality Sink positioned at, or in non-bypassable control of, a technical effectuation boundary. The architecture may be implemented within a single device, across multiple devices, across multiple trust domains, across cloud and edge infrastructure, or across combinations of local, remote, hardware-rooted, virtualized, and distributed execution environments. The execution substrate and Finality Sink may be co-located or separated. The Protected Enforcement Domain may be implemented independently of the execution substrate so that compromise or authorization of the execution substrate does not itself permit unauthorized external effectuation. FUNCTIONAL COMPONENTS Execution Substrate The Execution Substrate receives an operation request and performs a computation that generates a Candidate Output. The Execution Substrate may comprise:• an artificial-intelligence inference engine; • a cloud workload; • a processor; • a virtual machine; • a container; • an application server; • a database system; • a telecommunications component; • a network service; • a robotic controller; • an industrial controller; • a financial-processing engine; • a storage controller; • a mobile device; • an edge-computing node; or • any other system capable of producing a computational output. The Execution Substrate need not itself determine whether the Candidate Output is permitted to become externally effective. Non-Final Output Holding Mechanism The Non-Final Output Holding Mechanism prevents the Candidate Output from crossing the technical effectuation boundary before finality verification. The mechanism may comprise one or more of: • encryption of the Candidate Output under a protected key; • withholding of a decryption key; • withholding of a signing operation; • withholding of an output-release operation; • withholding of a routing authorization; • withholding of a transmit instruction; • placement in an isolated buffer;• placement in protected memory; • marking the output as non-effective; • preventing commitment to persistent state; • preventing downstream API invocation; • preventing actuator activation; • preventing external packet transmission; • preventing publication or user presentation; • preventing release to a downstream process; • withholding a protected-state transition necessary for effectuation. The technically non-final state is therefore not merely an advisory label or policy indication. It is enforced by a technical dependency whose satisfaction is required for external effectuation. Candidate Act Descriptor Generator The Candidate Act Descriptor Generator forms a deterministic representation of the produced Candidate Output. In one embodiment, the Candidate Output is canonicalized before digest generation. Canonicalization may include: • normalization of character encoding; • ordering of structured fields; • normalization of whitespace; • normalization of numeric representation; • removal or normalization of non-semantic metadata; • serialization according to a deterministic schema; • framing of binary objects; • selection of material output portions; • construction of a Merkle root; • construction of a manifest identifying multiple output fragments; • inclusion of destination-sensitive or effect-sensitive fields. The Candidate Act Descriptor may include: • an output digest;• a canonicalization-version identifier; • an invocation identifier; • a workload identifier; • a model or algorithm identifier; • an intended destination; • an interface identifier; • an effect type; • a tenant identifier; • a purpose identifier; • a jurisdiction identifier; • a time value; • a policy-epoch identifier; • a protected-state reference; • an output-length value; • a fragment manifest; • a provenance reference; • a grounding reference; • a runtime behavioral reference; • an external-effectuation classification. Protected Enforcement Domain The Protected Enforcement Domain evaluates whether the Candidate Output satisfies the conditions required for external effectuation. The Protected Enforcement Domain may receive: • the Candidate Act Descriptor; • the Candidate Output; • a protected representation of the Candidate Output; • an output digest; • execution measurements;• workload measurements; • policy data; • destination data; • recipient data; • authorization state; • provenance data; • behavioral descriptors; • grounding references; • revocation state; • anti-replay state; • policy-epoch state; • prior-use state; • security-context data. The Protected Enforcement Domain determines whether all required protected predicates are satisfied. Where a predicate is not satisfied, the Protected Enforcement Domain withholds the scoped non- bearer capability and may generate a protected denial record. Where the required predicates are satisfied, the Protected Enforcement Domain commits protected validation evidence before, or atomically with, release of the scoped non-bearer capability. Protected-State Repository The Protected-State Repository maintains state required to prevent unauthorized, stale, replayed, revoked, duplicated, or out-of-scope effectuation. Protected state may include: • capability issuance state; • capability consumption state; • invocation state; • output-digest state; • monotonic counters; • nonce state; • policy-epoch state;• revocation state; • quota state; • use-count state; • destination state; • tenant state; • effectuation-state commitments; • denial state; • prior-effectuation records. The repository may be implemented within the Protected Enforcement Domain, within the Finality Sink, within a hardware security module, within a trusted execution environment, within a protected database, or across multiple mutually validating protected systems. Finality Sink A Finality Sink is a logical, functional, physical, cryptographic, transactional, protocol-level, software-defined, hardware-rooted, distributed, centralized, or combined enforcement role that determines whether a Candidate Output, Candidate Act, or other prospective consequence is permitted to become externally effective. The Finality Sink is defined by its control function rather than by its physical location, component name, network position, deployment layer, device type, or implementation technology. A Finality Sink may be positioned: • within the same component that performs protected validation; • within the same processor, trusted execution environment, secure enclave, hardware security module, operating-system service, application, gateway, controller, or transaction engine that generates or validates the Candidate Output; • in a component separate from the execution substrate or Protected Enforcement Domain; • at an upstream, intermediate, downstream, local, remote, edge, cloud, device, network, storage, interface, or actuator location; • across multiple cooperating components that collectively perform the finality-verification function; or • at any point having mandatory control over a technical operation required for external effectuation. The Finality Sink need not be a physically separate downstream gateway. In some embodiments, a single protected component performs both: 1. validation of the protected predicates; and2. final verification and controlled effectuation. Such a component constitutes both a Protected Enforcement Domain and a Finality Sink where it maintains a technical separation between validation of the Candidate Output and the operation that permits the Candidate Output to become externally effective. The Finality Sink may be implemented as a single decision point, a single protected transaction, a protected state transition, a key-use controller, a signing controller, a commit controller, an output- release controller, a routing controller, a transmission controller, a persistent-storage controller, an actuator controller, an application-programming-interface broker, a user-interface release mechanism, or another component controlling a technically required effectuation operation. A Finality Sink may verify the required conditions: • directly from the Candidate Output and protected validation evidence; • by reconstructing a local Candidate Act Descriptor; • by consulting protected state; • by invoking a validation function within the same protected component; • by validating a reference to previously committed protected evidence; • by performing validation and effectuation within one atomic protected operation; or • through a combination thereof. Where validation and effectuation are performed within a single protected point, the Finality Sink may generate, validate, consume, and effectuate within one indivisible or ordered protected transaction, provided that the Candidate Output cannot become externally effective before the required output-specific predicates are satisfied. The Finality Sink therefore refers to the first technically controlling point, operation, state transition, or protected authority at which the Candidate Output can be rendered externally effective, rather than to any particular labelled device or architectural location. Location Neutrality The position of the Finality Sink is determined according to technical control over effectuation and not merely according to the direction of data flow. A Finality Sink may exist before, within, after, or alongside an execution substrate, provided that it controls a necessary effectuation operation. Accordingly, the Finality Sink may be: • co-located with the execution substrate; • co-located with the Protected Enforcement Domain; • integrated into a model-serving runtime; • embedded within an application;• implemented by an operating system; • implemented within hardware; • implemented by a network or storage controller; • distributed across mutually dependent components; or • implemented as a protected function invoked immediately before effectuation. No particular physical distance, network hop, trust-domain separation, or downstream placement is required. Single-Point Validation and Effectuation In one embodiment, the Protected Enforcement Domain and Finality Sink are implemented by a single protected enforcement point. The single protected enforcement point: 1. receives or accesses the Candidate Output; 2. computes or verifies an output-specific digest; 3. evaluates the required protected predicates; 4. commits protected validation evidence or an equivalent protected validation state; 5. verifies that the intended effectuation corresponds to the validated Candidate Output and permitted scope; 6. performs or authorizes a protected state transition; and 7. permits external effectuation only after successful completion of the preceding operations. The operations may occur sequentially within the single protected enforcement point or atomically within one protected transaction. Physical separation between validation and effectuation is not required. Logical separation is sufficient where the protected enforcement point prevents the effectuation operation from occurring unless the required validation state has been established. Anti-Bypass Closure The execution-finality architecture is configured so that the Candidate Output cannot achieve the intended authorized external effectuation through an alternative path that avoids the Finality Sink or avoids verification of the required finality conditions. Anti-bypass protection may be established through one or more technical dependencies, including: • exclusive custody of a key required to decrypt, sign, authenticate, transmit, commit, release, route, or actuate the Candidate Output;• mandatory operating-system, hypervisor, kernel, firmware, or hardware mediation; • mandatory routing through a controlled interface; • network, service-mesh, bus, queue, or protocol enforcement; • protected access to a device driver, actuator, storage namespace, database commit function, telecommunications interface, or external application interface; • capability-controlled invocation of the effectuation operation; • cryptographic binding between the Candidate Output and the only usable release operation; • sealed output that cannot be externally interpreted or used before sink-controlled release; • access-control rules that deny direct effectuation by the execution substrate; • hardware or protected-state conditions required for final effectuation; • removal or disabling of alternate release paths; • protected destination-side verification; • mutually dependent components that collectively prevent unilateral bypass; • an atomic consume-and-effectuate operation; • combinations thereof. A component does not cease to be a Finality Sink merely because another system physically transmits, displays, stores, or actuates the Candidate Output after the Finality Sink authorizes effectuation. The relevant question is whether bypassing the component would permit the Candidate Output to obtain the intended usable external effect. Where a downstream component performs only mechanical forwarding after a protected release decision has irreversibly enabled the Candidate Output, the earlier protected release point may constitute the Finality Sink. Where a downstream component retains independent technical control capable of denying the effect, that downstream component may constitute the Finality Sink or an additional Finality Sink. First Usable Effectuation Boundary The Finality Sink may correspond to the first point at which the Candidate Output is transformed from a non-effective or non-usable state into a state capable of causing the intended external consequence. The first usable effectuation boundary may comprise: • release of plaintext; • release of a cryptographic key;• generation of a valid signature; • commitment of a database transaction; • publication to a user interface; • release to a downstream agent or tool; • transmission through a network interface; • admission into a durable namespace; • issuance of a payment or settlement instruction; • activation of an actuator; • creation of an externally accepted protocol message; • another irreversible or practically usable release event. The Finality Sink is therefore not limited to the last physical device in an execution chain. It may be the earliest protected point whose successful operation makes the intended effect technically possible and whose denial keeps the Candidate Output technically non-final. Multiple Finality Sinks An architecture may include one or more Finality Sinks. Multiple Finality Sinks may operate: • sequentially; • hierarchically; • conjunctively; • independently for different effect types; • independently for different output fragments; • independently for different destinations or jurisdictions. A capability may be bound to: • one identified Finality Sink; • a protected set of permitted Finality Sinks; • a sink class; • a sink-selection predicate; or • a chain of required Finality Sinks.Where multiple Finality Sinks are required, failure at any required sink prevents the corresponding external effectuation. Functional Definition Prevails References in this disclosure to a gateway, boundary, output controller, release controller, broker, trusted component, secure module, or other implementation example do not limit the Finality Sink to that implementation. A component constitutes a Finality Sink when, by technical role, it performs or controls the final required verification or protected transition without which the Candidate Output cannot obtain the intended external effect. The term is therefore functional, implementation-neutral, location-neutral, and enforcement- mechanism neutral. EXEMPLARY WORKFLOW Stage 1: Operation Request Reception An operation request is received by the Execution Substrate. The request may include: • input data; • a command; • a prompt; • a transaction request; • an API invocation; • a workflow instruction; • a control request; • a network request; • a query; • a tool invocation; • a user action; • an agent-generated instruction. The operation request may be authenticated and authorized for computation. Such authorization does not authorize the resulting Candidate Output to become externally effective.Stage 2: Computation The Execution Substrate executes the requested computation. The computation produces a Candidate Output. The Candidate Output may be complete from a computational perspective while remaining incomplete from an effectuation perspective. For example, an artificial-intelligence model may complete inference and produce a textual response, but the response remains withheld from a user-facing interface until execution-finality verification succeeds. Stage 3: Non-Final State Enforcement The Candidate Output is placed or retained in a technically non-final state. The output may be: • held in an isolated buffer; • encrypted; • sealed; • unsigned; • unrouted; • uncommitted; • unavailable to an external interface; • unavailable to a downstream system; • prevented from activating a device; • prevented from modifying persistent state. The architecture prevents the output from becoming effective merely because computation completed successfully. Stage 4: Output Canonicalization The Candidate Output is deterministically transformed into a canonical output representation. The canonicalization method is selected according to the output type. For textual outputs, normalization may include a defined character encoding and line-ending format. For structured outputs, canonicalization may include deterministic field ordering. For multimedia outputs, canonicalization may include a manifest identifying content segments and their respective digests.For streamed outputs, canonicalization may be performed per fragment, per chunk, per segment, or according to a rolling commitment structure. Stage 5: Output Digest Generation A digest is computed over the Candidate Output or the canonical output representation. The digest identifies the Candidate Output actually produced. The digest is not merely a digest of the operation request. In some embodiments, the output digest excludes the request digest entirely. In other embodiments, the Candidate Act Descriptor may separately include both an output digest and a request-context reference, while preserving the output digest as a distinct output-specific value. Stage 6: Candidate Act Descriptor Formation The output digest and associated effectuation information are assembled into the Candidate Act Descriptor. The descriptor may identify what the Candidate Output is, where it is intended to be released, what effect it may produce, and what execution-finality conditions apply. Stage 7: Protected Predicate Evaluation The Candidate Act Descriptor is supplied to the Protected Enforcement Domain. The Protected Enforcement Domain evaluates one or more protected predicates. Example predicates include: • whether the output digest matches the Candidate Output; • whether the workload executing the computation is approved; • whether the runtime algorithmic state is approved; • whether the intended destination is authorized; • whether the effect type is permitted; • whether the output complies with a current policy epoch; • whether the output is grounded in approved source material; • whether the output falls within an authorized behavioral envelope; • whether the operation remains within a permitted quota; • whether the capability has been revoked; • whether the Candidate Output has previously been effectuated;• whether the Candidate Output is stale; • whether the jurisdiction is permitted; • whether protected authorization state remains valid; • whether an intended recipient is authorized; • whether a disclosure budget has been exceeded. Stage 8: Protected Validation Evidence Commitment Upon successful predicate evaluation, the Protected Enforcement Domain generates protected validation evidence. The protected validation evidence is bound to at least the Candidate Act Descriptor or output digest. The evidence may further be bound to: • the invocation identifier; • the protected-state transition; • the policy epoch; • the intended Finality Sink; • the permitted effectuation scope; • the destination; • the workload measurement; • the time of validation; • the anti-replay state; • the expected capability identifier. The validation evidence is committed before or atomically with capability release. Stage 9: Scoped Non-Bearer Capability Release After successful validation and evidence commitment, the Protected Enforcement Domain generates or releases a scoped non-bearer capability. The capability may contain, reference, or cryptographically commit to: • the output digest; • the Candidate Act Descriptor; • the validation-evidence identifier; • the Finality Sink identifier;• the effectuation scope; • the policy epoch; • an expiry condition; • a nonce; • a monotonic counter; • a use count; • an invocation identifier; • a capability identifier; • a protected-state reference; • a cryptographic authenticator. The capability is non-bearer because possession alone does not authorize use. Use requires correspondence with the bound Candidate Output, Finality Sink, evidence, scope, and protected state. Stage 10: Delivery to the Finality Sink The Candidate Output, Candidate Act Descriptor, protected validation evidence, and scoped non- bearer capability are delivered to or made accessible by the identified Finality Sink. The Candidate Output remains technically non-final during delivery. ANTI-BYPASS METHOD WITHIN THE WORKFLOW Stage 10A: Identification of the Required Effectuation Dependency Before permitting the Candidate Output to become externally effective, the system identifies at least one technical operation, protected state transition, protected resource, interface, key, controller, transaction, or release mechanism without which the intended external effect cannot occur. The required effectuation dependency may comprise: • access to a cryptographic key; • performance of a signing operation; • release of plaintext; • activation of a network interface; • authorization of a routing operation;• commitment of a database transaction; • admission into persistent storage; • invocation of a downstream application-programming interface; • release to a user-facing interface; • activation of an actuator; • issuance of a telecommunications transmission; • generation of an externally accepted protocol object; • release of an output-specific decryption capability; • update of protected state that enables external use; • another technically necessary effectuation operation. The required effectuation dependency is placed under exclusive, mandatory, or otherwise non- bypassable control of the identified Finality Sink or of multiple cooperating Finality Sinks. Stage 10B: Closure of Alternative Effectuation Paths The system identifies and technically restricts alternative paths through which the Candidate Output could otherwise obtain the intended external effect without successful Finality Sink verification. Alternative paths may include: • direct output release by the Execution Substrate; • an alternate application-programming interface; • a diagnostic or administrative interface; • an unmediated network connection; • direct access to a device driver; • direct access to a signing or encryption key; • an alternate database commit path; • an unprotected message queue; • a fallback communication route; • an alternate storage namespace; • a privileged software path; • a replicated output channel; • a recovery or maintenance interface;• an intermediate service capable of releasing the Candidate Output independently. The system closes, disables, denies, isolates, cryptographically prevents, or brings each relevant alternative path under equivalent finality enforcement. Anti-bypass closure may be implemented using one or more of: • exclusive key custody; • mandatory access control; • operating-system mediation; • kernel mediation; • hypervisor mediation; • secure boot; • hardware isolation; • protected routing; • service-mesh enforcement; • device binding; • driver-level mediation; • firewall rules; • namespace restrictions; • cryptographic sealing; • capability-controlled invocation; • destination-side verification; • protected transaction control; • removal of alternate credentials; • disabling of unverified fallback paths; • mutually dependent protected components. Stage 10C: Anti-Bypass State Binding The Candidate Act Descriptor, protected validation evidence, scoped non-bearer capability, or protected state may include an Anti-Bypass State Descriptor. The Anti-Bypass State Descriptor may identify: • the required effectuation dependency;• the authorized release interface; • the identified Finality Sink; • a permitted sink set; • the expected routing path; • an authorized device or controller; • a protected key identifier; • an expected software or hardware measurement; • an expected destination; • an expected protocol endpoint; • a mandatory transaction identifier; • a protected topology version; • an anti-bypass policy epoch. The scoped non-bearer capability may be bound to the Anti-Bypass State Descriptor so that use through a different release path, device, interface, key, route, or controller fails verification. Stage 10D: Verification of Mandatory Mediation Before effectuation, the Finality Sink verifies that the Candidate Output has reached the effectuation operation through an authorized mandatory path. The verification may include determining that: • the Candidate Output remains sealed or non-final until sink verification; • the effectuation key remains under sink control; • the current interface matches the authorized interface; • the current destination matches the authorized destination; • the current controller or device matches the authorized controller or device; • the current software or hardware measurement matches an approved measurement; • the required protected state has not been bypassed, substituted, or reset; • no alternate valid release capability exists outside the protected architecture; • the effectuation request was not rerouted through an unapproved path; • the current topology or policy epoch remains valid. Failure of mandatory-mediation verification causes denial of external effectuation.Stage 10E: Detection of Attempted Bypass The system may detect an attempted bypass when: • the Candidate Output appears at an unauthorized interface; • a release operation is requested without a corresponding capability; • a capability is presented to an unauthorized sink; • an unapproved key or controller is used; • a direct transmission is attempted by the Execution Substrate; • an alternate route is invoked; • a protected routing or topology measurement does not match; • the Candidate Output has been modified, copied, substituted, or re-encoded outside the authorized process; • protected consumption state is absent or inconsistent; • a fallback or recovery interface is used without finality verification. Upon detection of an attempted bypass, the system may: • deny the effectuation operation; • invalidate the capability; • consume the capability as denied; • quarantine or destroy the Candidate Output; • revoke related capabilities; • close the execution session; • increment a protected anomaly counter; • generate a structured bypass-denial record; • isolate the Execution Substrate; • require revalidation; • escalate the event for review. FINALITY SINK VERIFICATION STAGE Stage 11: Finality Sink and Anti-Bypass VerificationBefore the Candidate Output becomes externally effective, the identified Finality Sink, whether implemented separately or within the same protected point as the Protected Enforcement Domain, verifies: • authenticity of the scoped non-bearer capability; • correspondence of the capability to the Candidate Output; • correspondence of the capability to protected validation evidence; • correspondence of the capability to the identified Finality Sink or permitted sink set; • correspondence of the intended effectuation to the permitted effectuation scope; • validity, freshness, policy epoch, revocation, consumption, and anti-replay state; • integrity of the required effectuation dependency; • continued control of the required effectuation dependency by the Finality Sink; • satisfaction of the Anti-Bypass State Descriptor, where used; • use of an authorized release interface, route, controller, device, key, transaction, or protected state transition; • absence of an operative alternate path capable of producing the intended authorized external effect without equivalent finality verification. The Finality Sink may perform the foregoing verifications within a separate component, within the Protected Enforcement Domain, or within a single atomic protected operation. The Finality Sink may reconstruct a sink-local descriptor that includes both output-specific information and locally observed effectuation-path information. The locally reconstructed descriptor may comprise: SinkLocalDescriptor = { local_output_digest, local_sink_id, local_destination_id, local_interface_id, local_effect_type, local_controller_id, local_device_id, local_key_id, local_route_id, local_policy_epoch, local_topology_measurement, local_protected_state_reference } The Finality Sink compares the sink-local descriptor with the information bound into the scoped non-bearer capability and protected validation evidence. Any mismatch results in denial.ATOMIC CONSUME-AND-EFFECTUATE STAGE Stage 12: Atomic Validation, Anti-Bypass Confirmation, Consumption, and Effectuation Upon successful verification, the Finality Sink performs or authorizes the required effectuation operation while maintaining mandatory control over the effectuation dependency. The Finality Sink may execute, within a single protected transaction: 1. final validation of the Candidate Output; 2. verification of the scoped non-bearer capability; 3. verification of protected validation evidence; 4. verification of anti-bypass state; 5. reservation or consumption of capability state; 6. activation of the required effectuation dependency; 7. external effectuation of the Candidate Output; 8. finalization of protected consumption state; 9. generation of a finality receipt. The transaction is configured so that: • external effectuation cannot occur before required verification; • an alternative release path cannot substitute for the controlled effectuation dependency; • the capability cannot be consumed successfully without the corresponding effectuation; • the effectuation cannot occur without corresponding protected-state consumption or reservation; • replay or concurrent use cannot produce duplicate effectuation; • failure before completion leaves the Candidate Output non-final or causes protected recovery. FAILURE STAGE Stage 14: Failure or Bypass Handling If any required validation, finality, or anti-bypass verification fails, the system: 1. denies external effectuation; 2. refuses to activate the required effectuation dependency;3. withholds, rejects, invalidates, revokes, or consumes-as-denied the scoped non-bearer capability; 4. maintains the Candidate Output in the technically non-final state; 5. prevents use of any detected alternate effectuation path; and 6. optionally commits a protected denial or bypass-attempt record. A structured bypass-attempt record may include: BypassDenialRecord = { record_id, candidate_output_digest, invocation_id, capability_id, expected_sink_id, observed_interface_id, observed_route_id, observed_controller_id, policy_epoch, bypass_reason_code, protected_time, authenticator } Exemplary bypass reason codes include: B001 DIRECT_RELEASE_ATTEMPT B002 UNAUTHORIZED_INTERFACE B003 UNAUTHORIZED_ROUTE B004 WRONG_EFFECTUATION_CONTROLLER B005 EFFECTUATION_KEY_OUTSIDE_SINK_CONTROL B006 ALTERNATE_COMMIT_PATH B007 FALLBACK_PATH_NOT_FINALITY_PROTECTED B008 TOPOLOGY_MEASUREMENT_MISMATCH B009 DESTINATION_SIDE_VERIFICATION_ABSENT B010 PROTECTED_STATE_BYPASS_ATTEMPT ANTI-BYPASS PSEUDOCODE FUNCTION VERIFY_ANTI_BYPASS( candidate_output, candidate_act_descriptor, scoped_non_bearer_capability, local_effectuation_context ): required_dependency = IDENTIFY_REQUIRED_EFFECTUATION_DEPENDENCY( local_effectuation_context.effect_type ) IF FINALITY_SINK_CONTROLS(required_dependency) == FALSE:RETURN FAIL("EFFECTUATION_DEPENDENCY_NOT_CONTROLLED") IF candidate_output.is_non_final == FALSE: RETURN FAIL("OUTPUT_LEFT_NON_FINAL_STATE_PREMATURELY") IF local_effectuation_context.interface_id NOT IN scoped_non_bearer_capability.permitted_interfaces: RETURN FAIL("UNAUTHORIZED_INTERFACE") IF local_effectuation_context.route_id NOT IN scoped_non_bearer_capability.permitted_routes: RETURN FAIL("UNAUTHORIZED_ROUTE") IF local_effectuation_context.controller_id != scoped_non_bearer_capability.controller_id: RETURN FAIL("WRONG_EFFECTUATION_CONTROLLER") IF local_effectuation_context.destination_id NOT IN scoped_non_bearer_capability.permitted_destinations: RETURN FAIL("UNAUTHORIZED_DESTINATION") IF VERIFY_TOPOLOGY_MEASUREMENT( local_effectuation_context.topology_measurement, scoped_non_bearer_capability.expected_topology_measurement ) == FALSE: RETURN FAIL("TOPOLOGY_MEASUREMENT_MISMATCH") alternative_paths = DISCOVER_OPERATIVE_ALTERNATIVE_PATHS( candidate_act_descriptor, local_effectuation_context ) FOR EACH path IN alternative_paths: IF PATH_HAS_EQUIVALENT_FINALITY_ENFORCEMENT(path) == FALSE: DISABLE_OR_DENY(path) IF PATH_REMAINS_OPERATIVE(path): RETURN FAIL("UNCONTROLLED_ALTERNATIVE_PATH") RETURN SUCCESS INTEGRATED FINALITY PSEUDOCODE FUNCTION VERIFY_CONSUME_AND_EFFECTUATE( candidate_output, candidate_act_descriptor, protected_validation_evidence, scoped_non_bearer_capability,local_effectuation_context ): finality_result = VERIFY_OUTPUT_EVIDENCE_SCOPE_AND_STATE( candidate_output, candidate_act_descriptor, protected_validation_evidence, scoped_non_bearer_capability ) IF finality_result.success == FALSE: RETURN DENY_FINALITY(finality_result.reason) anti_bypass_result = VERIFY_ANTI_BYPASS( candidate_output, candidate_act_descriptor, scoped_non_bearer_capability, local_effectuation_context ) IF anti_bypass_result.success == FALSE: COMMIT_BYPASS_DENIAL_RECORD( candidate_act_descriptor, scoped_non_bearer_capability, local_effectuation_context, anti_bypass_result.reason ) MAINTAIN_TECHNICALLY_NON_FINAL_STATE(candidate_output) RETURN DENY_FINALITY(anti_bypass_result.reason) BEGIN_PROTECTED_FINALITY_TRANSACTION() IF RESERVE_OR_CONSUME_CAPABILITY( scoped_non_bearer_capability ) == FALSE: ROLLBACK_PROTECTED_FINALITY_TRANSACTION() RETURN DENY_FINALITY("CAPABILITY_STATE_FAILURE") IF ACTIVATE_REQUIRED_EFFECTUATION_DEPENDENCY( scoped_non_bearer_capability, local_effectuation_context ) == FALSE: ROLLBACK_PROTECTED_FINALITY_TRANSACTION() RETURN DENY_FINALITY("DEPENDENCY_ACTIVATION_FAILURE") IF EFFECTUATE_OUTPUT( candidate_output,scoped_non_bearer_capability.effectuation_scope ) == FALSE: ROLLBACK_OR_ENTER_PROTECTED_RECOVERY() RETURN DENY_FINALITY("EFFECTUATION_FAILURE") FINALIZE_CAPABILITY_CONSUMPTION( scoped_non_bearer_capability ) COMMIT_FINALITY_RECEIPT( candidate_act_descriptor.output_digest, scoped_non_bearer_capability.capability_id, local_effectuation_context, "EFFECTUATED" ) COMMIT_PROTECTED_FINALITY_TRANSACTION() RETURN SUCCESS EXEMPLARY METHOD FLOW The following method may be performed: S101: receive an operation request;

ORDINARY SKILL IN THE ART A person having ordinary skill in the art, after reading the present disclosure, can implement the architecture using known computing, cryptographic, networking, trusted-execution, policy- evaluation, and transaction-processing components without undue experimentation. The inventive architecture does not depend upon a particular programming language, processor family, cryptographic algorithm, trusted-execution technology, database, network protocol, or artificial-intelligence model. Exemplary Skill Level A person having ordinary skill in the art may include a software engineer, security architect, distributed-systems engineer, cloud engineer, telecommunications engineer, embedded-systems engineer, cryptographic systems engineer, artificial-intelligence infrastructure engineer, or a multidisciplinary team having equivalent practical knowledge. Such a person would ordinarily understand: • deterministic serialization; • cryptographic hashing; • digital signatures or message authentication codes; • trusted execution environments; • hardware security modules; • secure key storage;• access-control systems; • policy engines; • transaction processing; • replay prevention; • monotonic counters; • protected logging; • distributed-system consistency; • output buffering; • API gateways; • network enforcement points; • secure inter-process communication; • artificial-intelligence inference infrastructure. Implementing the Candidate Output State A skilled person may maintain the Candidate Output in a technically non-final state by preventing at least one technically required completion step. For a text-generation system, the Candidate Output may be held in memory and withheld from the client response stream. For a database system, a proposed modification may remain uncommitted until the Finality Sink authorizes transaction commitment. For a telecommunications system, a generated message may remain in a protected transmission queue until a gateway verifies the capability. For a robotic system, a movement command may remain unavailable to the actuator controller until the actuator-side Finality Sink completes verification. For a payment system, a transaction instruction may remain unsigned or unsubmitted until finality verification succeeds. For a storage system, a data object may remain encrypted or may remain excluded from a durable namespace until the Finality Sink authorizes persistence. Implementing Output Canonicalization A skilled person can select an appropriate deterministic canonicalization process according to the output format. For JSON data, object keys may be ordered lexicographically, numeric forms normalized, and insignificant whitespace removed.For XML, a canonical XML representation may be used. For plain text, a defined character encoding, normalization form, and line-ending convention may be applied. For binary files, the digest may be computed directly over the binary sequence or over a deterministic container representation. For streamed output, each output segment may be individually digested and combined using a Merkle tree, rolling hash, hash chain, or ordered manifest. The canonicalization-version identifier may be included in the Candidate Act Descriptor so that the Finality Sink applies the same canonicalization procedure. Implementing the Output Digest The output digest may be generated using a collision-resistant hash algorithm. Examples include SHA-256, SHA-384, SHA-512, SHA-3, BLAKE2, BLAKE3, or another suitable current or future digest function. The invention is not limited to a particular hash algorithm. A keyed digest or authenticated commitment may also be used. Implementing the Protected Enforcement Domain The Protected Enforcement Domain may be implemented using: • a trusted execution environment; • a secure enclave; • a hardware security module; • a secure co-processor; • an isolated virtual machine; • a protected kernel service; • a secure monitor; • a cryptographically authenticated software service; • a distributed quorum of protected services; • a combination thereof. The Protected Enforcement Domain protects at least the integrity of predicate evaluation and capability generation. In some embodiments, it also protects confidentiality of policy data, authorization state, model measurements, keys, or Candidate Outputs.Implementing Protected Validation Evidence The protected validation evidence may be represented as an authenticated data structure. An exemplary structure may include: ValidationEvidence = { evidence_version, evidence_id, output_digest, candidate_act_descriptor_digest, satisfied_predicate_ids, policy_epoch, invocation_id, sink_id, effectuation_scope_digest, protected_state_reference, validation_time, anti_replay_reference, authenticator } The authenticator may comprise: • a digital signature; • a message authentication code; • a hardware-rooted attestation; • an enclave-generated quote; • a ledger commitment; • a hash-chain commitment; • a combination thereof. Implementing the Scoped Non-Bearer Capability An exemplary scoped non-bearer capability may include: ScopedCapability = { capability_version, capability_id, output_digest, evidence_id, sink_id, permitted_effectuation_scope, invocation_id, policy_epoch, issuance_time, expiry_time, nonce,use_limit, protected_state_reference, authenticator } The capability is non-bearer because the Finality Sink does not authorize effectuation based solely on receipt or possession of the capability. The Finality Sink additionally verifies that: • the output digest matches; • the validation evidence matches; • the Finality Sink identity matches; • the requested effectuation falls within scope; • the protected state is current; • the capability has not been consumed; • the capability remains fresh and unrevoked. Implementing the Finality Sink The Finality Sink may be implemented as: • an API gateway; • a database commit controller; • a network egress gateway; • a message broker; • a user-interface release controller; • a model-output gateway; • a storage controller; • a payment-signing module; • a telecommunications gateway; • an actuator controller; • a device driver; • an operating-system broker; • a secure enclave; • a hardware security module;• a cloud sidecar; • a service-mesh enforcement component; • a kernel-level enforcement point; • a trusted application component. The Finality Sink must be positioned such that bypass of the Finality Sink does not produce the intended authorized external effectuation. This may be achieved by topology, cryptographic dependency, key custody, hardware isolation, routing control, operating-system mediation, transaction-control authority, secure boot, mandatory access control, or combinations thereof. Implementing Atomic Consumption and Effectuation A skilled person may implement atomic consumption and effectuation using: • database transactions; • compare-and-swap operations; • hardware monotonic counters; • transactional memory; • write-ahead logs; • two-phase commit; • protected state machines; • enclave-sealed state; • idempotency records; • consensus protocols; • atomic message-queue acknowledgement; • cryptographic one-time keys; • single-use capability registers. Where complete atomicity across separate systems is unavailable, a protected intermediate state may be used. For example: ISSUED → PRESENTED → RESERVED → EFFECTUATED → CONSUMEDor: ISSUED → PRESENTED → DENIED → INVALIDATED reconciliation. Recovery logic may ensure that a capability in a reserved state cannot be reused without protected Implementing Failure Handling The system may define deterministic failure codes such as: F001 OUTPUT_DIGEST_MISMATCH F002 CAPABILITY_INVALID F003 EVIDENCE_INVALID F004 WRONG_FINALITY_SINK F005 EFFECTUATION_SCOPE_VIOLATION F006 CAPABILITY_EXPIRED F007 CAPABILITY_REVOKED F008 POLICY_EPOCH_MISMATCH F009 REPLAY_DETECTED F010 PROTECTED_STATE_MISMATCH F011 DESTINATION_NOT_AUTHORIZED F012 PREDICATE_FAILURE F013 EFFECTUATION_TRANSACTION_FAILURE The failure code may be included in a protected denial receipt. Artificial-Intelligence Enablement Example An artificial-intelligence model receives a prompt and produces a response. The prompt may be authorized for inference. The generated response is retained in a non-final output buffer and is not yet transmitted to the user. The response is canonicalized and hashed. A Candidate Act Descriptor is created containing the output digest, model identity, session identifier, user-interface destination, policy epoch, and intended release scope. The Protected Enforcement Domain evaluates predicates including: • model-integrity status; • output-policy compliance; • grounding correspondence; • destination authorization; • disclosure limits; • session validity;• policy epoch; • replay state. After successful validation, protected validation evidence and an output-specific capability are generated. A user-interface output gateway functioning as the Finality Sink recomputes the response digest, validates the capability and evidence, confirms the release scope, consumes the capability, and then presents the response. Authorization of the prompt does not substitute for authorization of the generated response. Cloud-Service Enablement Example A cloud workload generates an API response. The API response is held by a sidecar proxy. The sidecar computes an output digest and submits the Candidate Act Descriptor to a Protected Enforcement Domain. The Protected Enforcement Domain evaluates tenant, purpose, destination, policy, runtime-integrity, and data-egress predicates. The resulting capability is bound to the response digest and to the destination API gateway. The gateway releases the response only after successful finality verification. Telecommunications Enablement Example A telecommunications application generates a message or call-control instruction. The generated communication artifact remains in a non-effective queue. A digest is computed over the message, routing data, or canonical communication representation. The capability is bound to the output digest, authorized route, destination, effect type, and telecommunications Finality Sink. The gateway verifies the capability before transmission. A valid request-side authorization cannot authorize a modified message having a different output digest. Cyber-Physical Enablement Example An autonomous or semi-autonomous controller generates an actuator command. The command is retained in a protected command buffer. A digest is computed over the command, target device, movement range, timing parameters, and safety scope.Protected predicates evaluate device state, safety policy, environmental conditions, command limits, and operator authorization. The actuator controller functions as the Finality Sink. Only the exact validated command may be executed. Variations The order of operations described herein may be modified where the required security properties are preserved. For example: • evidence commitment and capability issuance may occur within one atomic protected operation; • the Candidate Act Descriptor may be generated by the Execution Substrate or by the Protected Enforcement Domain; • the Finality Sink may retrieve the Candidate Output rather than receive it; • multiple Finality Sinks may be authorized according to a bounded sink set; • a capability may authorize one output fragment or multiple related fragments; • a sequence of Candidate Outputs may be governed using chained descriptors; • the protected predicates may be static, dynamic, compiled, learned, jurisdiction-dependent, destination-dependent, or effect-dependent; • cryptographic protection may be supplemented or replaced by hardware isolation, mandatory mediation, secure state, or other technically enforceable mechanisms. The foregoing examples are illustrative and do not limit the scope of the disclosed architecture. DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS General Architectural Principle The disclosed subject matter is based on the recognition that successful computation and authorized external effectuation are technically different events. Conventional systems frequently determine whether an operation request is authorized before executing a computation. Once the computation has been authorized, the resulting output may be released automatically or may be treated as implicitly authorized because it was produced by an authorized process. Such an arrangement may be inadequate where: • the produced output differs materially from the expected output;• the computation is compromised after request authorization; • the execution substrate is redirected, substituted, manipulated, or partially compromised; • the output contains unauthorized information; • the output is sent to an unauthorized destination; • a previously valid policy changes before output release; • a model produces an unsafe or ungrounded response; • an agent generates an externally consequential command; • an attacker reuses an authorization artifact with a different output; • request authorization is incorrectly treated as authorization for all resulting consequences. The present architecture introduces an execution-finality stage after production of the Candidate Output and before the Candidate Output becomes externally effective. The architecture therefore distinguishes among at least three states: 1. requested but not computed; 2. computed but technically non-final; and 3. verified and externally effective. The second state is a technically enforced intermediate state. It is not merely a descriptive or administrative classification. Computation Authorization Is Insufficient for Output Finality An operation request may be validly authorized. An execution substrate may also be validly authorized to execute the requested computation. Nevertheless, neither authorization necessarily establishes that a particular produced output is suitable for external effectuation. The system therefore treats request authorization as a first decision and output finality as a separate second decision. In one embodiment, a first gate determines whether computation may begin. A second gate determines whether the produced Candidate Output may cross a technical effectuation boundary. The second gate uses output-specific information that does not exist before the computation produces the Candidate Output. Accordingly, the second gate cannot be fully satisfied merely by information describing the operation request. Candidate Output FormationThe Candidate Output may be generated in full, incrementally, continuously, probabilistically, deterministically, or through a distributed computation. The Candidate Output may comprise: • a single complete artifact; • a plurality of output fragments; • a stream; • a proposed transaction; • an intended actuator command; • a set of database modifications; • a model-generated response; • an executable instruction; • a network transmission; • a structured decision object; • a collection of tool calls; • a plan generated by an autonomous agent; • a sequence of actions. The Candidate Output may be copied into a protected buffer, encrypted, sealed, or otherwise isolated from an external interface. Deterministic Output Representation In some embodiments, the Candidate Output is directly hashed without canonicalization. In other embodiments, the Candidate Output is first converted into a deterministic representation. The deterministic representation reduces ambiguity that could otherwise arise from semantically equivalent but bytewise different forms. For example, a structured output may contain fields whose order is not semantically significant. Canonicalization establishes a defined order before digest generation. A deterministic representation may also include effectuation-relevant information that is not part of the visible content itself. For an actuator command, the deterministic representation may include: • command type; • actuator identifier;• magnitude; • duration; • target position; • safety envelope; • execution time; • destination controller. For an artificial-intelligence output, the deterministic representation may include: • generated content; • output modality; • tool-call parameters; • destination; • model-session identifier; • response-sequence number; • output-fragment identifiers. For a financial transaction, the deterministic representation may include: • amount; • asset type; • beneficiary; • source account; • settlement network; • jurisdiction; • transaction nonce. Output-Specific Digest The output digest is derived from the Candidate Output or a deterministic representation thereof. This output digest differs from a request digest. A request digest may identify what was requested before execution. An output digest identifies what was actually produced. The Candidate Act Descriptor may contain both values, but the two values remain separately identifiable.In one embodiment, a capability bound only to a request digest cannot satisfy output- correspondence verification at the Finality Sink. In another embodiment, the Finality Sink rejects a capability if the capability lacks a protected binding to the output digest. Candidate Act Descriptor Structure An exemplary Candidate Act Descriptor may comprise: CandidateActDescriptor = { descriptor_version, invocation_id, output_digest, canonicalization_version, output_type, execution_substrate_id, workload_id, model_id, runtime_measurement, intended_sink_id, intended_destination_id, permitted_effect_type, tenant_id, purpose_id, jurisdiction_id, policy_epoch, creation_time, expiry_requirement, fragment_manifest_reference, grounding_commitment_reference, behavioral_descriptor_reference, protected_state_reference } Not every embodiment requires every field. The descriptor may be represented as a signed object, authenticated structure, protected record, serialized data object, capability input, or ledger-anchored commitment. Protected Predicate Selection The Protected Enforcement Domain may select applicable predicates according to: • Candidate Output type; • destination; • intended effect; • tenant; • purpose;• model identity; • user classification; • jurisdiction; • risk category; • workload measurement; • system state; • policy epoch; • requested effectuation scope. A policy compiler may convert high-level policy into executable predicates. Predicates may be evaluated sequentially, in parallel, hierarchically, or through a dependency graph. A predicate may return: • satisfied; • unsatisfied; • indeterminate; • unavailable; • stale; • requires escalation. Unless a policy expressly permits another result, an indeterminate, unavailable, stale, or unverifiable predicate result may be treated as failure. Protected Predicate Examples A protected output-integrity predicate may verify that the output digest corresponds to the Candidate Output. A provenance predicate may verify that required source records are authentic. A grounding predicate may verify that material output propositions correspond to approved or committed grounding units. A runtime-integrity predicate may verify an execution measurement. A behavioral predicate may determine whether runtime behavior falls within an approved behavioral envelope. A destination predicate may verify that the intended destination is authorized. A jurisdiction predicate may verify that effectuation is permitted within a specified territory.A disclosure predicate may determine whether releasing the Candidate Output would exceed a disclosure budget. A freshness predicate may verify that a capability is used within a permitted time interval. A revocation predicate may determine whether relevant authority has been revoked. A policy-epoch predicate may verify that the capability was issued under a policy epoch still accepted at the Finality Sink. A replay predicate may verify that an output-specific capability has not previously been consumed. Material Grounding Units In an artificial-intelligence embodiment, a Material Grounding Unit may comprise a source fragment, record, document portion, database field, retrieved passage, sensor record, authenticated observation, or another information unit materially relied upon to generate a Candidate Output. A Material Grounding Unit may be identified by: • a digest; • an object identifier; • a database reference; • a protected source reference; • a provenance commitment; • a content-addressed reference; • a signed source descriptor. The system may create a commitment over one or more Material Grounding Units. A grounding predicate may determine whether: • the Candidate Output is supported by the committed units; • the Candidate Output does not materially exceed authorized source content; • the cited source corresponds to the source actually used; • a required source remains valid; • an output claim is traceable to a grounding unit. The system need not prove every semantic property mathematically. A grounding predicate may use deterministic rules, a trusted classifier, a verified model, a human-approved mapping, a provenance graph, or combinations thereof. Runtime Behavioral DescriptorA Runtime Behavioral Descriptor may characterize behavior observed during execution of a computation. The descriptor may include: • tool calls; • memory accesses; • retrieval operations; • network destinations; • model components invoked; • control-flow features; • policy-engine interactions; • sensitive-data accesses; • output-generation paths; • use of external services; • privilege transitions. An approved behavioral descriptor may define permitted behavior. A protected predicate may compare the runtime behavioral descriptor with the approved descriptor. A mismatch may cause the Candidate Output to remain technically non-final even where the produced output appears superficially acceptable. Protected Validation Evidence After successful validation, the Protected Enforcement Domain commits protected validation evidence. The evidence may establish: • which Candidate Output was validated; • which predicates were evaluated; • which predicates succeeded; • which policy epoch was used; • which protected state was current; • which sink was authorized; • which scope was permitted;• which invocation was involved; • whether capability issuance occurred. The evidence may be immutable, append-only, tamper-evident, cryptographically authenticated, hardware-protected, or protected through a combination of mechanisms. Evidence-Before-Capability Ordering In one embodiment, protected validation evidence is committed before capability release. In another embodiment, evidence commitment and capability release occur atomically within one protected transaction. The architecture may prevent capability release where evidence commitment fails. This ordering reduces the risk that an authorization capability exists without corresponding protected evidence. Scoped Non-Bearer Capability A scoped non-bearer capability may be implemented as: • a signed token; • a message-authentication-code-protected object; • a hardware-bound object; • a protected handle; • a reference to protected state; • an enclave-bound object; • an operating-system capability; • a one-time cryptographic object; • a combination thereof. The capability may be opaque outside the Protected Enforcement Domain. The capability may not itself contain all bound data. It may instead reference protected state containing the bound data. The capability is not treated as a bearer token because presentation alone is insufficient. The Finality Sink additionally verifies correspondence with the exact Candidate Output, the identified sink, the permitted scope, the protected evidence, and current protected state. Sink Binding Sink binding may be implemented using:• a sink identifier; • a public-key identity; • a hardware-attested identity; • a device certificate; • a service identity; • a secure-channel endpoint identity; • a protected routing identity; • a hardware key; • an operating-system security principal. A capability presented to a different sink may be rejected. A bounded set of sinks may be authorized where the capability expressly identifies the set or a protected sink-selection rule. Permitted Effectuation Scope The permitted effectuation scope may constrain: • one or more destinations; • one or more recipients; • an output modality; • an interface; • an action type; • a maximum amount; • a jurisdiction; • a permitted time; • a number of uses; • a model session; • a device; • a tenant; • a data field; • an actuator range;• a communication route. The Finality Sink compares the requested effectuation with the permitted scope. A scope mismatch causes denial. Finality Sink Verification The Finality Sink may perform verification in a sequence selected for efficiency. For example, low-cost verification may precede expensive verification. An exemplary order is: 1. parse the capability; 2. verify capability format; 3. verify capability authenticity; 4. verify sink binding; 5. verify expiry; 6. verify policy epoch; 7. verify revocation state; 8. verify anti-replay state; 9. recompute the output digest; 10. verify output correspondence; 11. verify evidence correspondence; 12. verify effectuation scope; 13. reserve capability consumption state; 14. effectuate; 15. finalize consumption. Other orders may be used. Sink-Local Descriptor Reconstruction The Finality Sink may reconstruct a local descriptor from: • the Candidate Output; • local destination; • local interface;• local effect type; • local time; • local jurisdiction; • local recipient; • local device identity; • local policy epoch. The sink-local descriptor may be compared with the Candidate Act Descriptor bound into the capability. This prevents an intermediate system from changing an effectuation parameter after capability issuance. Atomic Consume-and-Effectuate In one embodiment, capability consumption and output effectuation occur as part of a single protected transaction. Where the Finality Sink controls a database, the consumption record and database modification may be committed in one transaction. Where the Finality Sink controls a network interface, the system may reserve a one-time capability, transmit the output, and finalize consumption only through a protected state machine that prevents duplicate transmission. Where the Finality Sink controls a signing key, capability consumption may be coupled to generation of a signature specific to the Candidate Output. Where the Finality Sink controls an actuator, consumption may be coupled to activation of the actuator command. Denial Handling Upon failure, the system may: • retain the Candidate Output; • quarantine the Candidate Output; • destroy the Candidate Output; • re-run validation; • request human approval; • generate a denial receipt; • revoke related capabilities;• increment an anomaly counter; • terminate the execution session; • isolate the execution substrate; • trigger incident response. In one embodiment, a denied capability is consumed as denied so that it cannot later be reused. In another embodiment, the capability remains unconsumed but invalidated. Artificial-Intelligence Output Embodiment An artificial-intelligence system receives a prompt and generates a response. The response is buffered before presentation. An output digest is computed over the generated response. A Candidate Act Descriptor identifies the response, model session, destination interface, policy epoch, and permitted release scope. The Protected Enforcement Domain evaluates predicates related to: • model integrity; • policy compliance; • grounding; • provenance; • confidentiality; • destination authorization; • disclosure budget; • behavioral conformity. A capability is released only after successful validation. The Finality Sink may be a response gateway, user-interface controller, tool-call broker, API gateway, or downstream-agent gateway. The Finality Sink recomputes the output digest and verifies the capability before release. Agentic Artificial-Intelligence Embodiment An artificial-intelligence agent may generate a plan comprising multiple intended actions. Each action may be represented as a separate Candidate Act. Alternatively, the complete plan may be represented as a composite Candidate Output.A separate capability may be issued for each action. The scope may specify: • tool identity; • API method; • destination; • amount; • parameter range; • use count; • completion deadline. A tool broker may function as the Finality Sink. The agent cannot exercise tool authority merely because it generated a tool call. Streaming Output Embodiment For a streaming output, the system may process output chunks. Each chunk may be: • individually digested; • included in a rolling hash; • committed in a Merkle tree; • associated with a sequence number. A capability may authorize: • one chunk; • a bounded group of chunks; • a complete committed stream; • continued release while a rolling predicate remains satisfied. The Finality Sink may stop release immediately when a later chunk fails validation. Split-Trust-Domain Embodiment A first trust domain performs computation. The Candidate Output is returned in a sealed or otherwise non-final state. A second trust domain contains the Finality Sink.The second trust domain independently validates the output digest, capability, evidence, destination, and scope. The second trust domain may prevent the first trust domain from unilaterally releasing the Candidate Output. Legacy Compatibility Embodiment The execution-finality architecture may be deployed around an existing application without retraining or materially modifying the application's computational logic. A shim, proxy, sidecar, gateway, operating-system broker, or service-mesh component may intercept the Candidate Output before external effectuation. The intercepted output is held while the Protected Enforcement Domain performs validation. Accordingly, legacy systems may receive execution-finality protection through mandatory mediation at the output boundary.
