# Audit measurement presence on every ad platform

> Tier: recipe. Operating recipe: real tool sequence, core rules, known traps.

Pixels and conversion wiring checked platform by platform, the measurement half of onboarding.

**Intent.** Which platforms have working event wiring, in one table.

## When to use

- Onboarding.
- Quarterly measurement hygiene.

## When not to use

- As the deep audit: tracking-audit crosses against GA4 and quantifies gaps.

## Sources

Required: any connected source

## Preconditions

- The account is ticked in the dashboard, confirmed via list_accounts.

## Inputs

- `window`: Analysis window. Default: last 30 days.

## Procedure

1. Check pixels and conversion setups everywhere. — tools: `meta_get_pixels`, `tiktok_get_pixels`, `pinterest_get_conversion_setup`, `google_ads_get_conversion_actions`
2. Table: platform, wiring present, last activity, optimised events.

## Decision rules

- **When** A platform spends without its own wiring → **conclude** It optimises blind: highest-priority measurement finding.

## Evidence requirements

- Every figure carries its account, metric and window.
- Anything below a readable sample size is reported as unjudged, not as zero.

## Human approval boundary

- The readout changes nothing. Any change it motivates goes through Safe Writes: preview, human confirmation, then apply.

## Failure modes

- Present is not correct: presence auditing finds absences, tracking-audit finds lies.

## Output

- **Readout**: The figures, with windows and accounts named.
- **Flags**: What deserves a deeper skill or a human decision.
