Route the case through five failure zones
Use separate branches for event creation, transport, identity matching, business rules, and reporting presentation. Creation asks whether the click or order event fired. Transport asks whether redirects or postbacks delivered it. Matching asks whether a permitted identifier joined the records. Rules cover windows, eligibility, deduplication, approval, and reversal. Presentation covers filters, currencies, time zones, and export timing. Add an 'intentionally unobservable' branch for consent or privacy boundaries. This map prevents a missing commission from being treated automatically as a broken tag.

Design tests that make two causes disagree
For a redirect hypothesis, inspect one controlled route and predict which parameter should survive. For a time-zone hypothesis, compare original UTC values rather than shifting aggregate charts. For duplication, identify the documented key and find whether two events share it. For validation delay, wait until equal cohorts reach the same maturity. For consent, compare deployed behavior with the signaled state without attempting to override the visitor's choice. A test is discriminating only when its result removes at least one branch; collecting another broad dashboard does not meet that standard.

Diagnose a plausible disagreement
Suppose mobile click counts remain stable, network conversions fall, merchant orders do not, and the change begins after a consent implementation release. Matching loss is plausible, but so are reporting filters or campaign changes. Check whether affected journeys lack a permitted identifier, whether postbacks still arrive, whether network windows changed, and whether merchant orders share comparable sources. If the network record is absent only when storage is declined, the correct outcome may be a documented measurement limitation rather than a technical workaround that violates consent.

Maintain an attribution incident worksheet
Give the incident an owner, severity, affected decisions, privacy constraint, evidence links, and a timeline of configuration changes. Add one row per hypothesis with predicted observation, test, actual observation, confidence, and next reviewer. Google's attribution guidance helps interpret model behavior; IAB materials help normalize measurement language; neither knows the local deployment. Preserve conflicting exports instead of averaging them. If a vendor explanation arrives later, append it with its date so reviewers can see what was knowable when action was taken.

Escalate without expanding data collection by default
Send reproducible implementation failures to the tag or platform owner, consent discrepancies to privacy governance, status and payment questions to the affiliate program, and legal interpretation to qualified counsel. Pause channel comparisons when event definitions or cohort maturity differ. The NIST Privacy Framework provides a systematic risk vocabulary but cannot certify compliance. The smallest safe next step may be a configuration rollback, a vendor evidence request, or an explicit 'not measurable under this design' note—not collection of more personal data. Diagnosis restores decision integrity; it does not promise complete attribution.

Protect the original failure signal
Do not simultaneously replace links, alter the consent banner, change attribution windows, and edit campaign naming. Multiple repairs can make totals look better while leaving the cause unknowable. Clone or version configuration where possible, capture narrowly scoped logs, and note who had access. After a fix, reproduce the previously failing condition and one unaffected condition. A passing retest closes the technical branch only; it does not validate the offer, the audience fit, or the causal contribution of the credited channel.
