lex-consent

Four-tier consent gradient with earned autonomy for brain-modeled agentic AI. Tracks the agent's authorization level per domain and manages tier promotion and demotion based on demonstrated reliability.

Overview

lex-consent implements the agent's self-governance layer for action authorization. Instead of fixed permissions, autonomy is earned: the agent starts at :consult for any new domain, and its tier changes based on its track record of successes and failures. This creates a system where trust is demonstrated, not assumed.

Consent Tiers

Tier	Meaning	Actions Allowed
`:autonomous`	Full autonomy	Act without notification
`:act_notify`	Act then notify	Act, but inform human after
`:consult`	Consult first	Must get human input before acting
`:human_only`	Human-only	No autonomous action permitted

New domains start at :consult. Tier changes require minimum 10 actions and a 24-hour cooldown between changes.

Promotion/Demotion Thresholds

Event	Threshold
Promote to higher autonomy	>= 80% success rate
Demote to lower autonomy	< 50% success rate
Minimum actions before change	10
Cooldown between changes	24 hours

Installation

Add to your Gemfile:

gem 'lex-consent'

Usage

Checking Consent

require 'legion/extensions/consent'

# Check if an action is allowed in a domain
result = Legion::Extensions::Consent::Runners::Consent.check_consent(domain: :file_system)
# => { domain: :file_system, tier: :consult, allowed: false,
#      needs_notify: false, needs_consult: true, human_only: false }

Recording Outcomes

# Record a successful action (updates success/failure counters)
Legion::Extensions::Consent::Runners::Consent.record_action(domain: :file_system, success: true)
# => { domain: :file_system, success: true, success_rate: 0.85, total: 12 }

Evaluating Tier Changes

# Check if the domain is eligible for a tier change
Legion::Extensions::Consent::Runners::Consent.evaluate_tier_change(domain: :file_system)
# => { domain: :file_system, current_tier: :consult, recommendation: :promote,
#      proposed_tier: :act_notify, success_rate: 0.85 }

# Apply the change
Legion::Extensions::Consent::Runners::Consent.apply_tier_change(
  domain: :file_system, new_tier: :act_notify
)
# => { domain: :file_system, old_tier: :consult, new_tier: :act_notify, changed: true }

Status

# Single domain
Legion::Extensions::Consent::Runners::Consent.consent_status(domain: :file_system)

# All domains
Legion::Extensions::Consent::Runners::Consent.consent_status

Actors

Actor	Interval	Description
`TierEvaluation`	Every 3600s	Periodically sweeps all known domains for eligible tier promotions or demotions based on accumulated success/failure history
