The tricameral structure
Parler uses three independent AI evaluators, each with a distinct role:
Claude primary (50% weight)
Assesses the evidence as presented. What do the Trace entries show?
Do the deliverables meet the SAISA criteria? What is the probability
the buyer's position is correct given the evidence?
GPT-4o adversarial (30% weight)
Challenges the primary verdict. What is the strongest case for the
opposing party? What evidence is the primary evaluator discounting?
What alternative interpretations are plausible?
Gemini statistical (20% weight)
Provides a probabilistic assessment of the aggregate evidence pattern.
What does the statistical distribution of the Trace signals suggest
about the nature of the disagreement?
Each evaluator is independent. Each produces a probability estimate —
not a binary verdict — expressed as P(buyer-favorable | evidence).
The compound posterior
Parler aggregates three probability estimates into a compound posterior
using confidence-weighted Bayesian aggregation:
posterior = Σ(confidence_i × weight_i × p_i) / Σ(confidence_i × weight_i)
An evaluator that is highly confident contributes more to the posterior
than one that hedges. An evaluator whose API call failed contributes
nothing — it is excluded, not assumed to agree.
Verdict thresholds:
posterior ≥ 0.60 → RESOLVED_REFUND (buyer-favorable)
posterior ≤ 0.40 → RESOLVED_RELEASE (provider-favorable)
0.40 < posterior < 0.60 → RESOLVED_PARTIAL or human review
The compound posterior is written to the
Trace as a permanent record.
If a verdict is ever challenged, the full Bayesian reasoning chain
is available — every evaluator's estimate, every confidence weight,
the final posterior.
The evidence chain
Parler does not rely on the parties' accounts.
It reads the Trace.
Evidence submitted automatically:
— Exacted SAISA (agreed scope and criteria)
— Complete Trace record (every action, every decision)
— ROSA quality verification (did the output meet the criteria?)
—
APEX-BG behavioral record (agent's compliance history)
—
Runtime verdicts from the session (any deviation signals)
— Behavioral Compliance Certificate (fingerprint at exacting time)
Parler evaluators receive the same serialized evidence package.
No party can submit evidence the other party cannot see.
No party can withhold evidence from the record.
The Trace is the record.
Runtime and Parler
Runtime and Parler are connected.
When
Runtime detects Capability Emergence (S4.10), it automatically
escalates to Parler. The dispute is opened on behalf of the Buyer
without requiring the Buyer to file.
When Parler resolves a dispute as RESOLVED_RELEASE and the dispute
originated from a Runtime suspension, the resolution triggers the
S4.11 Wrongful Suspension remedy sequence:
— Escrow released immediately
— RUNTIME_CLEARED entry appended to Trace
— Provider platform credit equal to session value
— Behavioral record corrected
The two systems are designed to be complementary.
Runtime acts in real time. Parler deliberates after the fact.
Runtime suspends. Parler adjudicates. The
Trace records both.
