Proposal: Quality gates between layers via SOURCES convention

[magnus919]

Summary

Adopt a convention that concept files at the analysis layer MUST include a SOURCES body section pointing to at least one file at the concept or dossier layer. Files at the synthesis layer MUST include a SOURCES section pointing to at least one analysis file. This creates directional quality gates between layers — a claim cannot move up the hierarchy without evidence beneath it.

Motivation

OKF's permissive consumption model accepts any content at any quality level. This is the right policy for an interchange format, but it provides no guidance for production pipelines that need to verify knowledge quality before routing it downstream. Without quality gates, there is no structural distinction between a well-supported analysis and an unsupported assertion.

Proposal

Adopt a layered quality gate convention enforced by the SOURCES section:

• A file with layer: concept or layer: dossier has no upward provenance requirement (it IS the evidence)
• A file with layer: analysis MUST have a SOURCES section listing at least one file at concept or dossier layer
• A file with layer: synthesis MUST have a SOURCES section listing at least one file at analysis layer

The gate criteria are specific and falsifiable: every summary claim links to an analysis file, every analysis claim links to a dossier, every dossier has a source URL or transcript. A claim that cannot trace to evidence at the layer beneath it does not move up.

Relationship to Spec

This is a production convention, not a spec requirement. It depends on the layer field (issue #93) and SOURCES section (issue #92) to function. Permissive OKF consumers ignore the gates entirely. Pipeline orchestrators use them to validate routing contracts before delivering bundles to downstream agents.

Prior Art

The artifact-pyramids agent skill (github.com/groktopus/artifact-pyramids) enforces these gates in production. The mechanism is structural, not procedural: a summary file whose SOURCES section references L2 files that do not exist yet is structurally incomplete. The gate is enforced by the SOURCES convention itself, not by a separate validation pass.

This is a strong direction. We've effectively run this exact layered-SOURCES
gate in production — a single-domain agent knowledge base (enterprise IT service
management, ~250 atomic notes, hardened over ~140 build cycles) — so a few field
notes, plus the one dimension flagged here as out of scope.

Where the gate held up. The core rule — "a claim that cannot trace to
evidence at the layer beneath it does not move up" — is exactly the discipline
that kept our corpus honest, and pairing it with inline per-claim citation (#94)
rather than a footnote block is what we landed on too: sentence-level
traceability is what makes it machine-checkable.

The dimension we found we couldn't skip: traceability ≠ trustworthiness.
A SOURCES gate proves a claim is grounded. It doesn't tell a consumer how much
to trust the ground — and for an agent that doesn't just retrieve but acts on
a live system, that gap is where damage happens. Two claims can both cite a URL
and be worlds apart:

• "the vendor docs state X" — grounded, but docs are often stale or aspirational
• "observed on the live system: X" — grounded, and verified against reality
• "inferred from adjacent facts; not yet verified"

Same citation mechanics, very different trust. So alongside the structural
gate we run a small reliability layer that's been load-bearing:

• a graded confidence level per note (HIGH / MEDIUM / LOW / UNVERIFIED) in
  frontmatter — distinct from "is it cited";
• a small provenance vocabulary on the inline citations (observed-on-system
  vs. documentation vs. partner-confirmed vs. inferred), so the kind of
  evidence is visible, not just its URL;
• an explicit trust ordering when two cited sources disagree
  (observed > partner-confirmed > observed+doc > doc > inferred), and a
  conflict marker whose rule is "document both sides, never silently pick".

The taxonomy itself is domain-specific and not the interesting part. The
interesting part is that these turned out to be interoperability needs, not
just internal hygiene: the moment a bundle crosses an org boundary — OKF's whole
purpose — the consumer loses all of the producer's out-of-band sense of which
claims are solid. Citation survives the hop; "how much do I trust this"
currently doesn't.

Two honest questions rather than a pitch:

1. Do you see graded confidence / trust-on-conflict as a natural extension of the
   SOURCES gate, or as a separate concern that deserves its own convention?
2. If it's worth its own thread, I'm glad to write it up as a focused proposal
   (an optional confidence: field + a provenance-tag convention riding
   on Proposal: Inline citation as default convention for coupling claims to evidence #94),
   with our production usage as a worked example — didn't want to fork the
   discussion without asking first.
