Purpose and prediction gate
List every prominent link and button with its visible label, accessible name, context, destination or state change, and consequence. Ask an unfamiliar reader to predict what each will do. W3C requires link purpose to be determinable from text or programmatic context and notes that users may inspect links separately. Fail the gate when different destinations share ambiguous text, when a visible and accessible label disagree, or when a commercial commitment is disguised as generic continuation. The inventory must include repeated, sticky, card-level, icon-only, and footer actions—not only the primary hero button.
Visible and programmatic labels communicate the same consequence.
Identical labels serve equivalent purposes in equivalent contexts.
External navigation, data sharing, payment, and download are distinguishable.

Readiness and evidence gate
For each action, name the reader question it answers and the minimum evidence needed first. Confirm that fit, material limits, price or price route, relationship disclosure, and destination are available at the decision point. NICE advises considering the reading path before placing a button. Fail when urgency or visual dominance appears before qualification, when the action interrupts access to supporting evidence, or when every reader stage receives the same commercial prompt. A valid early CTA can lead to comparison or explanation rather than commitment.
The action follows enough context for an informed prediction.
A cautious reader can inspect evidence and material terms before commitment.
Alternative, defer, and leave paths remain available.

Element and hierarchy gate
Confirm that navigation uses a link and in-interface operations use a button with native behavior. Review heading order, focus order, visible focus, contrast, target size, and whether multiple primary styles compete. GOV.UK recommends specific action text and warns against more than one main button; the U.S. Web Design System provides link accessibility checks. Fail when CSS styling conceals the element's behavior, a whole-card click creates nested interactive conflicts, or a warning action looks identical to a reversible ordinary step.
Semantic role matches actual behavior and keyboard expectations.
One current primary action is apparent without erasing necessary secondary paths.
Warning, destructive, and reversible actions have appropriate distinctions.

Placement and altered-display gate
Inspect every placement in content order and at small viewport, zoom, large text, touch, and representative assistive technology settings. Sticky prompts must not cover evidence, consent, navigation, or error messages and need an operable dismissal where persistence is nonessential. Repeated CTAs must retain the same consequence and disclosure context. Fail when layout reordering causes an action to precede its qualification, when focus lands on an off-screen control, or when a fixed element consumes the usable reading area. Record devices and configurations rather than approving from a design canvas.
Source order and visual order preserve the intended decision sequence.
Persistent controls remain non-obstructive and dismissible where appropriate.
Repeated placements do not change meaning as surrounding evidence changes.

Success, failure, and recovery gate
Activate each path under normal, slow, error, and duplicate-input conditions. Verify loading status, success confirmation, retry, preserved work, back navigation, edit, cancel, and support. For external merchant links, confirm destination relevance and return behavior without asserting control over stock or price. A control fails if the reader cannot tell whether it worked or if the only recovery is restarting an expensive process. Button appearance is a small part of this gate; the contract includes the state the organization creates and the remedy it provides.
Status feedback appears promptly and is announced accessibly.
Errors identify the problem and provide a feasible next action.
Readers can return, cancel, edit, or escalate in proportion to consequence.

Post-launch fit and revalidation gate
Name a primary handoff measure and guardrails before release. Combine activation with destination arrival, qualified completion, errors, support, cancellations, refunds, accessibility reports, and reader misprediction. Do not declare success from clicks alone. Assign an owner and reopen the audit when label, destination, commitment, page context, affiliate relationship, layout system, or offer terms change. Archive the inventory and test evidence so later teams can distinguish a deliberate action hierarchy from accumulated buttons. The CTA passes only when its purpose, timing, operation, and recovery remain aligned.
Activation is paired with a downstream task-quality measure.
Adverse outcomes have thresholds and accountable owners.
Specific content, commercial, and technical changes trigger renewed review.
