hypothesis-entry

1. The four strategies

Each strategy writes its own vendor-native Layer 0 artifact. The shared contract is oase.hypothesis-assessment.v1, emitted by each strategy's analyze command. There is no single score comparable across strategies. score is an object carrying {value, basis} or null; cross-strategy comparison is a judgement the program lead makes in prose.

2. When to prefer each strategy

3. Tool invocations

Adoption (sponsor, charter, prior-program, publication)

# Phase 1: adopt the hypothesis set
oase hypothesis adopt hypotheses.json \
  --origin sponsor \
  --attest "Provided by Dr. Smith on 2026-09-01 as starting material for the CDK4 program" \
  [--cite DOI:10.1234/example]

# Phase 2: assess the adopted set
oase hypothesis analyze raw/hypotheses/<slug>.adopted.json

Co-Scientist (unchanged)

oase coscientist ingest export.json [--top N]
oase coscientist analyze raw/hypotheses/cs-<session>.tournament.json

4. Mandatory relays

5. The no-silent-substitution rule

If the sponsor named a strategy and oase doctor reports it unavailable, the lead reports blocked. It does NOT silently substitute another.

A substituted strategy produces a differently-shaped artifact with a different score basis. A silent substitution is a provenance error that surfaces much later, when a finding cites an artifact whose shape does not match what the sponsor expected.

Check availability:

oase doctor --json | jq '.checks[] | select(.name | startswith("hypothesis strategy"))'

6. Threshold sets

7. Assessment output

Every strategy's analyze emits the shared oase.hypothesis-assessment.v1 core:

{
  "schema": "oase.hypothesis-assessment.v1",
  "strategy": "adopted | coscientist | hypex",
  "source_artifact": "raw/hypotheses/...",
  "source_sha256": "...",
  "candidates": [
    {
      "candidate_id": "...",
      "statement": "...",
      "rank": null,
      "score": null,
      "origin": "adopted | generated"
    }
  ]
}

For adopted sets: rank is always null, score is always null. For ranked strategies: score is {value: <number>, basis: "<set>"} — never a bare number.
