What goes in, what comes out, where it stops.
Inputs
- Evidence records from the Inspector
- Principal assessment of the four remaining surfaces
- The canonical entity graph
- Stated acceptance criteria
Outputs
- A prioritised remediation sequence
- The implemented change itself
- A completion record with re-run condition
- Regenerated machine-readable outputs
Boundary
Implementation is bounded by the recorded finding. A change with no finding behind it cannot be verified afterwards, so it is not in scope.
The chain, by artefact
Each stage names what exists at that point and the condition that must hold before the next begins.
Evidence record
State · Observed
Produced by the Inspector against a public property. Carries its own source, class and confidence.
Principal assessment
State · Reviewed
The four surfaces the instrument cannot reach. Judgement is attributed as Reviewed, never as Observed.
Remediation sequence
State · Prioritised
Findings ordered, with the ordering justified. No finding enters implementation without a recorded identifier.
Implemented change
State · In implementation
The change itself, referencing the finding it resolves. Machine-readable outputs regenerated with it.
Verification run
State · Re-run
The original condition re-measured by the method that first recorded it, at its stated version.
Completion record
State · Verified
Baseline, change and resulting state recorded together, with unresolved conditions named.
The five surfaces
The Machine Surface is the one the Inspector measures directly and without charge. The remaining four are assessed under Website Intelligence, where observation is read against business effect.
Human Surface
What a person encounters: whether the proposition, scope and next action are legible without prior context.
- Inspects
- Proposition clarity
- Navigational orientation
- Action hierarchy
- Reading order and contrast
- Expected output
- A record of where a reader loses the thread, and at which step.
- Verification
- Re-read against the same criteria after the change, with the finding referenced by identifier.
Machine Surface
What machines can discover, interpret, attribute, retrieve and cite from the public property — the surface the Inspector measures.
- Inspects
- Crawl directives
- Canonical entities
- Structured data
- Attribution and citation paths
- Expected output
- A deterministic evidence record per condition, each with its own source.
- Verification
- The Inspector is re-run and the condition compared against the recorded baseline.
Technical Surface
How the system behaves under real conditions: delivery, resilience and the security boundary.
- Inspects
- Response and rendering behaviour
- Failure modes
- Security headers and transport
- Runtime boundaries
- Expected output
- Observed behaviour against stated expectations, with failure modes named.
- Verification
- Deterministic checks re-run against production after deployment.
Publishing Surface
Whether what is published agrees with itself across every human and machine representation.
- Inspects
- Canonical facts
- Feed and index agreement
- Entity coherence
- Stale or contradictory claims
- Expected output
- A list of disagreements between representations of the same fact.
- Verification
- Machine outputs regenerated and compared for byte-level agreement.
Measurement Surface
Whether the system can be observed at all: if a condition cannot be measured, an improvement to it cannot be demonstrated.
- Inspects
- Instrumentation coverage
- Event integrity
- Attribution of outcomes
- Reporting honesty
- Expected output
- A statement of what is currently measurable, and what is not.
- Verification
- Measurement re-checked against a known event before conclusions are drawn from it.
From observation to verification
Implementation is the stage this page describes. It is not the first stage, and it is not useful without the ones before it — a change implemented against no recorded finding cannot be verified afterwards.
- ObserveMachine Surface InspectorA public evidence record of what machines can discover and attribute.
- InterpretWebsite IntelligenceFindings read against business effect, with confidence and evidence class stated.
- PrioritiseEvidence matrix and remediation sequenceAn ordered sequence: what to change, in what order, and why that order.
- ImplementYou are hereRemediation sprint or website systemThe governed change itself, implemented against the recorded finding.
- VerifyCompletion record and surface assuranceThe condition re-run after the change, with variance recorded against baseline.
