Skyzai.ORG -- Evidence Tiers
Five rungs, two qualifiers. Every claim is marked. No claim may be presented at a higher tier than its actual status.
Why Tier Discipline Matters
Most whitepapers and technical documents make claims without distinguishing between what they have proven and what they believe. A reader cannot tell whether a statement rests on a written design, a simulated run, a reproducible local receipt, or an independently verified measurement.
Skyzai marks every claim with an evidence tier. This is not stylistic -- it is a constitutional requirement (A7: self-correction). If you cannot label the evidence behind a claim, you do not understand the claim well enough to make it. [D]
Violating tier discipline triggers A7 self-correction. [D]
The Ladder (canonical)
The maturity ladder is strictly ordered: [C] < [D] < [S] < [B] < [E]. A claim earns a rung; it is never granted one.
| Rung | Name | Meaning | What it takes |
|---|---|---|---|
| [C] | Conjecture | An idea, a thesis | Stated with reasoning |
| [D] | Doc / spec | A written, buildable design | The artifact exists and is internally coherent |
| [S] | Simulated | A mocked/fixture run, or a scaffolded contract | A run/scaffold exists, honestly labeled SIMULATED/scaffold |
| [B] | Observed | A real local/prototype run with an exported artifact and reproducible steps | A dated receipt plus the generator/steps to reproduce it |
| [E] | Measured | Independently verified in an authorized/live environment | Third-party or production measurement plus the applicable typed authority and receipt |
Cross-cutting qualifiers (not rungs)
- [I] — inferred / architectural reasoning. Marks how a claim is known, not how proven it is.
- [A] — non-permutable structural invariant.
[I] and [A] qualify claims; they never substitute for [B]/[E] on a runtime claim. A design argued from architecture is at most [D] with an [I] qualifier.
Promotion Requirements
No artifact advances a tier without (i) a named, reproducible proof artifact, (ii) the exact run/scope it proves, and (iii) a Proof-steward seal — and the promotion applies only to that specific loop, never to the whole system.
| From → To | Required proof | Non-upgrade clause |
|---|---|---|
| [C] → [D] | The written spec, coherent, tiers marked | A doc is not a run |
| [D] → [S] | A mock/fixture run or scaffolded contract, labeled | A sim is not a real event |
| [S] → [B] | A dated real run + exported artifact + reproducible steps | A receipt proves only its own loop |
| [B] → [E] | Independent/authorized measurement plus the applicable typed authority receipt | One org's run is not the network |
A7 Correction Triggers
Open an A7 correction before proceeding if any surface says or implies, beyond its earned tier: live product · live wallet · live network · live settlement · live SoResFi · live Layer-1 · live 6G · production signing · verified identity · health / financial / legal advice.
Rules
- Never cite a lower rung as support for a higher one. A conjecture [C] cannot support a spec claim [D]; a spec cannot support an observed-run claim [B]. Evidence flows down, not up.
- Always mark the tier. Every non-trivial claim in Skyzai documentation carries a tier label. Unmarked claims are treated as [C] by default.
- Promote and demote actively. When new evidence arrives, re-tier the affected claims. This is A7 in action. Demotion needs no ceremony; promotion needs a receipt.
- Scope every promotion. A receipt proves only the loop it recorded. A working local run promotes that loop to [B]; it does not promote the system.
- Conjectures are welcome. The [C] rung is not a mark of shame. It is a mark of honesty. Better to label a speculation as speculation than to present it as proven.
Historical Note
Earlier versions of this page defined a four-tier epistemic alphabet ([E]stablished / [S]tructural / [I]nterpretive / [C]onjecture). That alphabet was merged into the maturity ladder above (per the tier merge-gate record): the rungs now measure how proven an artifact is, and the epistemic dimensions survive as the [I]/[A] qualifiers. When reading older pages, treat legacy "[E] established math" style labels as claims to re-tier, not as ladder rungs.
