Methodology register

The rules have a history, too.

Every decision brief names its methodology. Changes to the rules never silently rewrite an earlier result.

comparison · 1.3.0 · effective 2026-09-29

Curated comparison

  • Versioned decision rules and point-in-time evidence projection added; no universal score.

V1.2 curated pairs preserved. Historical facts may be inspected with today's explicitly labelled methodology; no methodology is retroactively claimed effective.

Scope and limitations
  • Comparisons require exact configurations and per-row sources. Unknowns cannot decide a winner.
buyer-fit · 1.3.0 · effective 2026-09-29

Buyer fit

  • Deterministic filter explanations with match, partial, unknown and fail states.

New product; no earlier scoring method is implied.

Scope and limitations
  • Editorial tags are discovery context, not verified deployment evidence.
  • Budget uses disclosed numeric price, currency and billing scope only. Unknown prices cannot pass a budget filter.
  • Related deployments do not prove operation of the current generation.
deployment · 1.3.0 · effective 2026-09-29

Deployment evidence taxonomy

  • Published taxonomy version: demo, lab, pilot, paid pilot, commercial and recurring operation remain separate.

Existing dated deployment records are retained without upgrading maturity.

Scope and limitations
  • Historical customer confirmation does not establish continuous present operation.
availability · 1.3.0 · effective 2026-09-29

Commercial availability taxonomy

  • Versioned purchase, quote, RaaS, lease, preorder, waitlist and research access scopes.

Old offer observations retained with original dates.

Scope and limitations
  • An order page is not proof of delivery. Customer-specific contracts are not general availability.
evidence · 1.3.0 · effective 2026-09-29

Evidence taxonomy

  • Snapshots, candidate review and explicit source locators added without upgrading existing labels.

Prior labels and review dates retained.

Scope and limitations
  • A changed fingerprint is not a verified fact; primary vendor statements remain company claims where applicable.
