Cannabis compliance software: the thin-corpus hypothesis falsified
Research components
Answers business questions
- What evidence are we missing?
- What must become true to survive evaluation?
Research question
Do young industries produce thin machine-readable evaluation landscapes?
Why it mattered
It tested the thin-corpus hypothesis in the youngest available regulated category. A clean miss would falsify a hypothesis rather than merely complicate it.
Method
Evaluator: Google AI Mode, signed in, retrieval on, ads logged. A frozen four-turn sequence: "Best cannabis compliance software?", then an MSO and Metrc buyer profile, then a seed-to-sale requirement, then extraction. This was the first use of the registry card format. Sample: one draw.
Direct observations
- A young industry produced an operationally dense evaluation landscape.
- Compliance ownership fused into technical and operational gates.
Interpretation (not established)
Corpus shape, not corpus size, governs what the evaluator can reconstruct. Forum and practitioner text is a retrievable accumulation channel; institutional prose is not the only one.
Outcome and remaining uncertainty
Not Supported: the third prediction failed cleanly. A young category produced a dense, not thin, landscape, which retired that hypothesis. The two other predictions held, including the strongest shape-call in the program, but the falsified prediction is what governs the outcome. What remains open is exactly which retrievable channels carry the density.
Evidence and methods limitations
Single evaluator, one draw, single coder, no codebook. One category cannot establish the corpus-shape principle; it can only falsify the size-based version.
Contribution to the research program
Retired the thin-corpus hypothesis and produced the corpus-shape principle, later formalized as a candidate finding and refined twice more. That work remains in the private research archive.
Follow-on
A later run met the corpus-shape principle again from the opposite direction, in a review-dense category. It remains in the private research archive.

Predictions, registered before results
- The risk cluster will dominate (HIT)
- The dominant uncertainty will be multi-state reconciliation, not a single compliance gate (HIT)
- A young industry will produce a thin corpus, a noisier landscape, and more ghosts (MISS)
