Assumption Miner

Heterogeneous services independently list what the material assumes but does not state. Cross-tier disagreement on assumptions reveals hidden dependencies.

Description

Heterogeneous services independently surface unstated assumptions; cross-tier disagreement reveals hidden dependencies.

Metadata

• version: 0.1.0

Slots

• miner (primary)
  • requires: material, context
  • ensures: assumptions
• comparator
  • requires: assumption_lists_by_tier
  • ensures: classified_assumption_map

Config

• tiers (object[], default: {'model': 'opus', 'count': 3}, {'model': 'sonnet', 'count': 2}): Miner configurations specifying model tier and count per tier

Invariants

• Each miner receives the same material and identical instructions
• Miners work independently — no miner sees another's output

Shape

• self: fan out to miners across tiers, collect assumption lists, delegate comparison
• delegates:
  • miner: list unstated assumptions in the material — run across tiers
  • comparator: classify assumptions by agreement pattern across tiers
• prohibited: none

Requires

• Pattern instance receives: miner: string -- service or system name for each miner comparator: string -- service or system name for the comparator material: string -- the corpus or artifact to examine tiers: object[] -- miner configurations, e.g. [{ model: "opus", count: 3 }, { model: "sonnet", count: 2 }] context: string -- (optional) domain context to help miners distinguish assumptions from common knowledge

Returns

• Each miner receives the same material and is asked: "What does this assume is true but not explicitly state?"
• Miners work independently — no miner sees another's output
• Comparator receives all assumption lists and classifies each assumption:
  • Universal: surfaced by all tiers — a KNOWN implicit dependency (widely recognizable)
  • Deep: surfaced only by higher tiers — a HIDDEN dependency (requires expertise to notice)
  • Contested: services disagree on whether it IS an assumption — may be a FALSE assumption or a point of genuine ambiguity about what the material presupposes
  • Phantom: surfaced by lower tiers but not higher — likely a MISREADING, not an actual assumption
• result: the comparator's classified assumption map
• raw_assumptions: per-miner assumption lists with tier metadata

Delegation

let raw_assumptions = parallel for tier in tiers:
  repeat tier.count:
    let assumptions = call miner
      material: material
      context: context
      prompt: "List every unstated assumption, where it is required, and what breaks if it is false."
      model: tier.model
    return {
      tier: tier.model,
      assumptions: assumptions
    }

let result = call comparator
  assumption_lists_by_tier: raw_assumptions
  material: material
  context: context
  prompt: "Classify assumptions as universal, deep, contested, or phantom, with tier evidence."

return {
  result: result,
  raw_assumptions: raw_assumptions
}

Notes

This is a seed pattern. Miners do not know other miners exist. The comparator does not know it is part of an assumption miner pattern. The key distinction from blind-review: blind-review asks "what does this say?" and measures comprehension. Assumption miner asks "what does this NOT say?" and measures implicit dependencies. A document can score perfectly clear on blind-review while harboring deep unstated assumptions that only the assumption miner surfaces. The most dangerous assumptions are the DEEP ones — dependencies that are real, load-bearing, and invisible to most readers.
