DAS grades the unit
Not the brochure. Not the last good call. The practice behind every call.
Boards and agencies buy intelligence on reputation. Nobody shows them how a provider grades its sources, whether its probabilities mean anything, or whether its work ever changed a decision. DAS puts a number on that practice. An auditor opens the unit's ledger, draws a sample of judgments, and recomputes the grade. The band either holds or it does not.
The standard at a glance
- Grades: an intelligence unit, the team that owns a product line, its ledger, and its consumers.
- Three layers: evidence, effect, and calibration.
- Five bands: Ad hoc, Documented, Graded, Measured, Calibrated.
- Three marks: DAS-Registered, DAS-Certified, DAS-Distinguished.
- Rests on: the ASA Evidence Standard, Public Edition 1.2, and ASA Measurement of Effect.
3
Three gate rules. One failure in the sample blocks the band.
Every judgment keeps verified fact apart from adversary claim. Every judgment carries a Sherman Kent probability band. Every source in the ledger carries a grade.
A unit that clears all three on the sample, and conforms on at least 90 percent of it, holds Band 3. Below the line, the unit stays in the buyer's pool and knows the gap.
DAS certifies practice, not truth. A Band 5 unit still misses calls. Its ledger shows how often.
Bought on reputation
Audit standards govern the accounts, the controls, and the data center. The intelligence that tells a board who is coming and why gets bought on a logo and a sample report.
Ungraded evidence
A finding from a state outlet and a finding from a court filing arrive with the same weight. The reader never sees the difference.
Probability as decoration
"Likely" means 60 percent to one analyst and 90 to the next. Nobody keeps score, so the word stops carrying information.
No trace to a decision
Reports ship. Nobody records which decision each one informed or whether the decision changed.
The provider grades the provider
Capability statements come from the seller. A buyer has no ledger, no sample, and no independent read.
Three layers, one ledger
DAS composes two published Treadstone 71 standards and adds a third test. The unit keeps one append-only ledger of items, grades, judgments, forecasts, and outcomes. The auditor recomputes everything from it. A result the auditor cannot reproduce does not stand.
Layer 1 · Evidence
Does every judgment rest on graded evidence? The layer applies the ASA Evidence Standard. Source reliability and information credibility sit on separate axes and never average. The three gate rules apply to the sample.
Layer 2 · Effect
Did the work change a decision, a belief, or a behavior? Units that run campaigns take Path A and measure under ASA-MOE. Units that write assessments take Path B, a decision-trace record that ties each product to the decision it informed.
Layer 3 · Calibration
Did the unit's confidence track reality over time, including when an adversary planted a false signal? A forecast ledger and a deception exercise answer the question. Version 1.0 carries the layer as Provisional until a pilot reports.

Notify Me on ReleaseDAS-RegisteredScoping form filed
The unit names its product lines, consumers, ledger system, and claimed band. The form publishes with the mark. No fee.
DAS-CertifiedBand 3 or Band 4, audited
An independent auditor samples the ledger, runs the gates, and signs an Audit Statement with the ledger hash.
DAS-DistinguishedBand 5, audited
Issued once the calibration pilot reports. Until then, a unit that meets Layers 1 and 2 and runs the exercise claims Band 5 (Provisional).
Each band holds the one below
A unit cannot hold a higher band without every lower one. DAS bands grade a unit; the ASA T-Score bands grade a single item. The two scales stay apart.
| Band | Name | Evidence layer | Effect layer | Calibration layer |
|---|---|---|---|---|
| 1 | Ad hoc | No standing ledger; grades vary by analyst | Not recorded | Not recorded |
| 2 | Documented | Ledger exists; rules written, not applied to every judgment | Not recorded | Not recorded |
| 3 | Graded | Gates G1 to G3 pass; 90 percent of the sample conforms | Not required | Not required |
| 4 | Measured | Band 3 holds | Path A or Path B met | Not required |
| 5 | Calibrated (Provisional) | Band 4 holds | Band 4 holds | Forecast ledger kept; deception exercise run; results reported |
File the scoping form
Name the unit, its product lines, its consumers, its ledger, and the band claimed. DAS-Registered follows.
Keep the ledger
Append-only. An edit becomes an amendment that cites the original. Twelve months of entries make an audit period.
Open the sample
The auditor snapshots the ledger, records its SHA-256 hash, and draws the judgment sample.
Run the gates and the layers
Gates first, then the conformance rate, then the effect path, then calibration where claimed.
Publish the Audit Statement
Band, mark, ledger hash, and every difference between the unit's figures and the auditor's.
Open standard. Any qualified auditor.
DAS does not require Treadstone 71. Any qualified independent party is free to audit to it. Treadstone 71 writes the standard and also offers audits, and the standard publishes the controls on that conflict: the ledger hash, full recomputation, and an internal review log on every audit.

Before you write it into a contract
What does DAS grade?
An intelligence unit: a team of analysts that produces assessments for a named consumer, inside a government office, a company, a bank, a vendor, or a nonprofit. DAS does not certify an individual analyst, a single product, or a data feed.
How does a buyer use it?
Write the band into the contract. The provider then shows a ledger, a sample of judgments, and an Audit Statement in place of a capability brochure.
Does a Band 5 unit get every call right?
No. DAS certifies practice, not truth. The ledger shows how often a unit misses and whether its stated confidence matched its record.
Why is the calibration layer Provisional?
The design has not yet run at scale. Version 1.0 keeps the layer out of the certification gate, and no DAS-Distinguished mark issues until the pilot reports in a later revision.
How does DAS relate to the ASA Evidence Standard?
The evidence layer applies ASA Public Edition 1.2 (DOI 10.5281/zenodo.23137881) without change. ASA grades one item. DAS grades the unit that handles thousands of them.
Does an audit require Treadstone 71?
No. Any qualified independent party is free to audit to the standard and issue an Audit Statement.
When does it publish?
Draft 0.7 issued internally on November 17, 2026. Version 1.0 publishes December 15, 2026.
Ask your provider for the ledger.
Then ask what band it earns. Version 1.0 publishes December 15, 2026.
