Companion contracts: # veritas_governance.py (parameters/admin) and module_registry.py (module # identity/policy). VeritasCore never calls ModuleRegistry at runtime # (Architectural Invariant A3) — every module field a task needs is # caller-supplied at submit() time and bound to ModuleRegistry's original, # validated values via hash verification (see ModuleSnapshot and # _compute_snapshot_hash below). # # GOVERNANCE INVARIANT G4 — SCOPE BOUNDARY, enforced deliberately narrowly: # submit() (this file) and register_module() (module_registry.py) are the # ONLY two methods in this entire protocol that check is_paused(). Every # other write method — evaluate(), finalize(), dispute_by_submitter(), # challenge(), update_module(), and every VeritasGovernance method — must # never check it. A pause that blocked in-flight evaluation or dispute # resolution would trap every existing task mid-process, a strictly worse # failure mode than whatever incident prompted the pause. # # ECONOMIC INVARIANT E4: every bond forfeiture/refund emits a settlement # event recording the exact split that occurred (_trace_settlement() here; # a matching inline event at ModuleRegistry's registration-forfeiture # site) — required because the split ratio is a mutable governance # parameter, so a later "read the current parameter" cannot reconstruct a # past settlement. Both files use the same event schema, with inapplicable # roles (e.g. owner/treasury on a full refund) explicitly zeroed rather # than omitted. # # `owner` is part of the canonical snapshot-hash field list (State # Invariant S5), identical in both _compute_snapshot_hash implementations, # and a field on ModuleSnapshot: submit()'s bonding logic needs the module # owner's address to pay the submission-bond owner-share correctly, and # since VeritasCore never calls ModuleRegistry (A3), owner has to arrive # as a caller-supplied, hash-verified field like every other module field. # See _compute_snapshot_hash's and ModuleSnapshot's docstrings. # # Off-chain discoverability (§2.10): every event in the specification's # normative minimum set is emitted under its canonical name with its # required fields — ModuleRegistered/ModuleUpdated (module_registry.py), # TaskSubmitted, TaskEvaluated, DisputeLogged, DisputeResolved, # ReputationUpdated, ModuleFlagged, BondCollected, BondRefunded, # BondForfeited. # ═══════════════════════════════════════════════════════════════════════════════ import hashlib import json from dataclasses import dataclass from datetime import datetime, timezone from genlayer import * # ══════════════════════════════════════════════════════════════════════════════ # Module-level pure helpers # # CRITICAL GenVM rule: any function reachable from a non-deterministic # entry point must have ZERO self.* or storage references.

Never returns a bare number — always adjusted score + raw counts + a sample_confidence label, so a consumer can judge how much weight the score deserves, not just read it blindly (this is itself a specification requirement, not a nicety). prior_weight is read LIVE from VeritasGovernance on every call, per the specification's explicit requirement — never cached locally.

Requires is_governance_configured — reverts cleanly rather than silently returning a misleading zero score during the window between deployment and configure(), when protocol_total_disputes would otherwise still be zero. FIXED-POINT IMPLEMENTATION (GenVM has no native float type — GenLayer Invariant GL3): rather than compute prior_mean as an intermediate rounded fraction and then apply it (which would lose precision), this substitutes prior_mean's own division algebraically before doing any rounding, giving a single exact integer ratio: adjusted = (unchanged + prior_weight * (p_unchanged / p_total)) / (total + prior_weight) multiply through by p_total to clear the inner fraction: adjusted = (unchanged * p_total + prior_weight * p_unchanged) / ((total + prior_weight) * p_total) Scaled to basis points (REPUTATION_BPS_SCALE = 10000) with exactly one floor division, at the very end, not before.

Given the two invariants this protocol maintains — unchanged <= total (per-module, enforced by _update_reputation's own increment order) and p_unchanged <= p_total (protocol-wide, same reasoning) — the numerator is bounded: unchanged*p_total + prior_weight*p_unchanged <= total*p_total + prior_weight*p_total = p_total*(total+prior_weight), which is exactly the denominator. So numerator <= denominator always, meaning the ratio never exceeds REPUTATION_BPS_SCALE; every term being non-negative means it's never below 0 either. p_total > 0 is guaranteed by configure()'s own asserts (re-validating whatever VeritasGovernance returns) — the guard above ensures configure() has run before this method proceeds. prior_weight > 0 is guaranteed by VeritasGovernance's own __init__ and propose_action() validation (SET_REPUTATION_PRIOR_WEIGHT can never be proposed with value <= 0) — this contract trusts that guarantee for the proof but still re-reads the live value rather than assuming it never needs to look again.
