Institutional trust surface

Validation

The validation surface reports on the integrity of the observability platform. Detailed engineering signals are reserved for authorised institutional review. The summaries below report the platform’s public-facing integrity posture only.

Section 01

System validation

The platform runs a structured validation suite covering ingestion, parsing, derived-metric calculations, lineage continuity, provenance rendering, exports, role permissions, public/private isolation, and integrity. Failure of any declared check blocks public deployment.

  • Validation suite latest resultNo failed checks recorded on the latest validation run.
    passing
  • Deployment block statusNo declared check is currently in a failed state.
    cleared
  • Role isolationPublic, restricted, and administrative surfaces enforce their declared role boundaries.
    verified
Section 02

Audit integrity

Every observation, methodology change, lock event, and access decision is recorded against an append-only, hash-linked audit record. On every read the platform re-verifies the chain in place.

  • Append-only audit chainHash links re-verified on every read; tamper-evident by construction.
    intact
  • Cross-domain audit linkageMethodology, observation, and access events are linked into a single integrity record.
    continuous
  • Engineering inspection of the raw audit chainDetailed chain inspection is restricted to authorised institutional review.
    reserved
Section 03

Methodology assurance

Every derived metric has a registered formula, source dependencies, assumptions, limitations, and a published version history. Where a question cannot be answered observationally, it is recorded in the non-computability registry rather than estimated.

  • Methodology consistencyAll published metrics resolve to a registered methodology entry.
    verified
  • Non-computability declaredLimitations are declared, not concealed.
    0 items
  • Methodology versioningMethodology versions are recorded against every output.
    tracked
Section 04

Lineage integrity

Every output declares its source document, parser version, methodology version, and the deterministic calculation that produced it. Lineage is continuous from publication record through to the displayed value.

  • Source-to-output lineageEvery public value resolves back to its source publication.
    continuous
  • Provenance envelopes on exportsCSV, JSON, and report exports carry tamper-evident provenance envelopes.
    enforced
  • Publication coverage classificationEach reporting period is classified by publication completeness, not interpolated.
