Module: SmartBrain::Governance::Tiers

Defined in:
lib/smart_brain/governance/tiers.rb

Overview

Mind-model tiers (mempal parity): dao_tian 天道 / dao_ren 人道 / shu 术 / qi 器 / evidence 证据. Lower ORDER index = higher assembly priority.

Constant Summary collapse

ORDER = 
%w[dao_tian dao_ren shu qi evidence].freeze
PRIORITY = 
ORDER.each_with_index.to_h.freeze
DEFAULT_TIER_BY_TYPE =

Default tier per memory type. dao_tian is never auto-assigned — it is reserved for user-pinned immutable principles.

{
  'profile' => 'dao_ren',
  'decisions' => 'dao_ren',
  'patterns' => 'dao_ren',
  'goals' => 'shu',
  'tasks' => 'shu',
  'preferences' => 'qi',
  'cases' => 'qi',
  'entities' => 'evidence',
  'events' => 'evidence'
}.freeze
DISTILLABLE =

Only dao_ren / qi knowledge can enter the candidate stage via distill (mempal rule: dao_tian and shu are not open to candidate state).

%w[dao_ren qi].freeze
CONTEXT_LIFECYCLE =

lifecycle statuses that participate in automatic context assembly.

%w[raw promoted].freeze
