Call Provenance in Pay-Per-Call: Tracing a Call from Creative to Buyer Outcome

A call can look simple in a report.

One row may show a timestamp, caller identifier, publisher, buyer, duration, disposition, and amount. That row can be useful. It is not the full story.

The consumer may have moved through an advertisement, landing page, tracking session, publisher ping, buyer selection, route reservation, multiple telephony legs, CRM disposition, and later financial adjustments.

Call provenance is the documented chain of records that helps an operator reconstruct that journey.

It should help answer where a call came from, what consumer experience preceded it, how it entered and moved through the routing system, which rules affected it, what happened at the buyer, and how the eventual financial status was determined.

That does not mean every call will have a perfect, complete, uncontested history. Systems can miss events. Clocks can disagree. Identifiers can be dropped. A buyer CRM may not match the routing platform. A recording may be unavailable. A publisher may be unable to produce the exact creative version. A final explanation may therefore include confidence levels, missing evidence, competing interpretations, or an unresolved exception.

The practical standard is not “the system always knows everything.”

It is this:

Every call should be explainable through a real record trace, including an honest account of what is known, what is inferred, what is missing, and what remains unresolved.

That is the operational substance behind why every call should be explainable. This article focuses on the lineage itself: the connected records from consumer-facing creative through routing, buyer outcome, and financial treatment.

This article is educational and operational, not legal advice. Advertising, telemarketing, consent, call-recording, privacy, retention, licensing, and recordkeeping duties vary by jurisdiction, vertical, technology, party role, and consumer journey. Qualified counsel should review the requirements that apply to a specific campaign.

What call provenance means

The W3C PROV overview describes provenance through entities, activities, people, attribution, processing steps, versioning, procedures, and derivation.

Applied to pay-per-call, call provenance is a linked account of the entities, decisions, events, and rule versions that produced a call outcome.

A useful provenance trace may connect:

• A publisher operating entity.
• A source and sub-source.
• A campaign, domain, brand, channel, and acquisition method.
• A creative and landing-page version.
• A tracking number, session, request, or call identifier.
• Any applicable permission, disclosure, or consent evidence.
• A ping or inbound-call event.
• Buyer eligibility evaluations and responses.
• A route reservation and selection decision.
• Caller-identifier matching.
• Telephony bridge and status events.
• A controlled buyer-target reference.
• Recording, QA, disposition, and CRM records where permitted.
• Qualification, conversion, duplicate, dispute, adjustment, billing, and payout events.

The important word is linked.

Records across multiple systems do not create useful provenance unless they can be connected reliably. A creative without a source identifier, a call without versioned terms, a CRM outcome without a shared key, or an invoice without call-level support leaves a material gap.

Call provenance is therefore both a recordkeeping problem and an identifier-design problem.

Provenance is not the same as attribution, reporting, or proof

Several related concepts are often collapsed into one. They serve different purposes.

This distinction matters because operators often overvalue the artifact they can see most easily.

Each party may favor its own system, but a record can be authoritative for one fact without being authoritative for every question.

A representative call-lineage walkthrough

The following is a labeled hypothetical using synthetic identifiers. A consumer sees a paid-search home-service ad, taps a click-to-call button, routes to an eligible buyer, and later receives an appointment disposition. Finance then evaluates buyer billing and publisher payout.

A defensible provenance trace would move through the following stages.

1. Publisher and operating entity

The trace begins with the legal or operating entity responsible for the traffic relationship.

The record may show:

• Publisher account identifier.
• Contracting entity.
• Approved operating contacts.
• Account status at the time.
• Authentication credential or controlled endpoint used.
• Whether sub-publishers were permitted.

This establishes who was authorized to send the traffic. It does not prove which specific marketing path produced the call.

A publisher name alone is usually too broad. One publisher may operate owned sites, paid search, social traffic, affiliate sources, and transfer centers. Provenance needs the next layer.

2. Source and sub-source

The source record should distinguish the traffic path at a level that supports review, routing, reporting, and investigation.

A stable source structure may identify:

• Owned-and-operated versus third-party traffic.
• Channel or media type.
• Source family.
• Sub-source or partner, when contractually and operationally permitted.
• Approved call type.
• Review status and effective dates.

This is where scoped transparency matters. A buyer may need a durable source reference and enough context to evaluate the traffic without receiving the publisher’s entire vendor list or proprietary media strategy.

The source identifier should remain stable; otherwise it becomes a bucket rather than provenance.

3. Campaign, domain, brand, channel, and acquisition method

The next records describe the consumer-facing commercial context.

For the hypothetical call, the trace might connect the source to:

• Campaign identifier.
• Vertical and service category.
• Domain and brand presented to the consumer.
• Paid-search channel.
• Geographic targeting.
• Device type.
• Consumer-initiated click-to-call path.
• Campaign configuration version.

This helps establish what kind of call opportunity the system believed it was evaluating.

It still does not show the actual message the consumer saw. That requires versioned creative evidence.

4. Creative version and claims

The creative record should identify the advertisement or message variant that preceded the call when the channel and technology make that possible.

Useful fields can include:

• Creative identifier and version.
• Headline and material claims.
• Call-to-action wording.
• Brand references.
• Effective and retirement dates.
• Review status.
• Reviewer or approval event.
• Channel-specific variation.
• Archived representation or hash of the reviewed artifact.

This stage connects provenance to consumer expectation.

A recording may reveal that a caller expected a free government benefit, a local contractor, or customer service. It cannot show whether an ad created that expectation. The operator needs the creative and landing-page chain discussed in why creative and landing page review matters for inbound calls.

The Federal Trade Commission’s .com Disclosures guidance is useful when reviewing how qualifying information appears in digital advertising. Presence alone is not the same as a clear consumer-facing disclosure.

5. Landing page, disclosures, form, or click-to-call experience

The landing-page record should preserve the material experience that led to the call.

Depending on the journey, that may include:

• Page URL and version.
• Page or template identifier.
• Visible brand and offer.
• Material disclosures.
• Form fields and submission behavior.
• Privacy notice version.
• Click-to-call button text.
• Dynamic number insertion context.
• Mobile rendering.
• Thank-you or transfer step.
• Timestamped capture or reproducible version reference.

Preserve enough versioned evidence to investigate material questions. One screenshot may miss dynamic content, device differences, personalization, or changed scripts.

6. Call-tracking number or session identifier

The tracking layer connects the consumer interaction to the telephone event.

The trace may use:

• A static campaign number.
• A dynamically assigned number.
• A web session identifier.
• A publisher request identifier.
• A click identifier.
• A tracking key tied to a controlled campaign assignment.
• A platform call identifier.

A strong design avoids making the raw phone number the only join key. Phone numbers can be reused, formatted differently, suppressed, changed, or treated as sensitive personal information. A non-sensitive internal call or correlation identifier is usually a safer backbone.

The record should also show the limits of the match. A dynamic number may support a strong session match; a shared static number may support only campaign-level attribution.

7. Permission, disclosure, or consent records when applicable

There is no universal consent field that answers every legal and operational question.

A provenance trace may need to distinguish:

• Permission to receive a call.
• Permission to make a later call or send a message.
• Consent to use a particular dialing or voice technology.
• Disclosure or consent for call recording.
• Agreement to a privacy notice.
• Authorization to share information with specified parties.

Where a legal or campaign requirement applies, the record may need the exact disclosure or consent version, presentation method, consumer action, timestamp, party or seller covered, purpose, and evidence source.

Current federal rules illustrate why the record must be specific. Where the FTC’s Telemarketing Sales Rule applies, 16 CFR 310.5 requires covered sellers and telemarketers to retain specified telemarketing records, including substantially different advertising and scripts, call details, and certain consent records. The FCC’s 47 CFR 64.1200 separately addresses consent and delivery restrictions for particular call types and technologies.

Those rules do not apply identically to every inbound journey, and other laws or contracts may add requirements. Record the evidence and policy actually relied upon rather than a generic “compliant” label.

8. Publisher ping or inbound-call event

The call now enters the routing operation.

In a pre-call model, the publisher may send a ping containing the agreed decision fields. In a call-time model, the inbound call itself may trigger the routing decision.

The event may preserve:

• Request identifier.
• Authenticated publisher or endpoint.
• Trusted tracking key.
• Campaign context.
• Source and sub-source values.
• Geography and call type.
• Received timestamp.
• Validation result.
• Duplicate or replay handling.
• Redacted request representation.

This event proves that a routing opportunity reached the system. It does not prove a buyer accepted it or that the live call arrived.

9. Bid requests, eligibility decisions, responses, and rejection reasons

A provenance trace should show more than the winning buyer.

It should preserve enough information to explain:

• Which targets were considered.
• Which targets were excluded before contact.
• Which rules caused exclusion.
• Which buyer endpoints were contacted.
• Which responses were accepted, declined, malformed, timed out, or errored.
• Which price and qualification terms were returned where appropriate for internal review.
• Which rejection or failure reason applied.
• Which routing-policy version was used.

A vague “no buyer” status hides whether the cause was schedule, cap, source eligibility, geography, a normal decline, timeout, malformed response, or another failure. Those outcomes have different owners and remedies.

The mechanics between a request and live delivery are covered more fully in what happens between a publisher ping and a buyer call. Provenance adds the requirement that those decision records remain connected to the earlier creative and later outcome.

10. Reservation and routing selection

Once a path is selected, the system may create a short-lived reservation or another controlled routing instruction.

The record may include:

• Reservation identifier.
• Selected target reference.
• Creation and expiration times.
• Single-use status.
• Expected caller or request match.
• Publisher-safe route handle.
• Frozen commercial and qualification inputs.
• Selection reason or rank.

The protected buyer destination should not be exposed merely to make the trace “complete.” An internal reference can establish which controlled target received the call without placing a private destination in a publisher report or broad audit export.

11. Caller-ID and identifier matching

When the live call arrives, the system needs to connect it to the expected opportunity.

Possible matching inputs include:

• Reservation identifier.
• Tracking number or route handle.
• Caller ID, when permitted and required.
• Publisher request identifier.
• Time window.
• Campaign and source context.
• SIP or telephony-provider identifiers.

The trace should record the match result and its confidence or failure reason.

A match may be exact, partial, ambiguous, or absent. Record uncertainty rather than forcing a weak match into the closest reservation.

12. Telephony bridge, timestamps, connection, and duration events

Telephony providers generate their own identifiers and status events. For example, Twilio’s Call resource documentation describes call identifiers, parent-child relationships, timestamps, statuses, and durations.

The provenance trace may distinguish:

• Inbound caller leg.
• Buyer or destination leg.
• Parent and child call identifiers.
• Ringing, answer, bridge, and completion timestamps.
• No-answer, busy, failed, canceled, or completed status.
• Provider-reported duration.
• Connected or billable-duration calculation.
• Webhook receipt and processing status.
• Retry or duplicate callback handling.

A provider’s “completed” status is not a commercial conclusion; the campaign rule still determines qualification, billability, and payability.

13. Buyer target and controlled destination reference

The call record should identify the buyer-side target that received the call.

That may include:

• Buyer account reference.
• Target identifier.
• Campaign assignment.
• Schedule and eligibility version.
• Controlled destination reference.
• Destination health state at route time.
• Buyer-side source enablement state.

A buyer may need to see its target and the approved source reference. A publisher may need a buyer-path or demand reference sufficient to explain acceptance and payout. Neither party automatically needs the other party’s private destination, internal price, payout, margin, or unrelated relationship data.

14. Recording, QA, disposition, and CRM outcome where permitted

After connection, several evidence streams may develop.

The operation may receive:

• Recording metadata or media where lawful and approved.
• Transcript or QA findings.
• Buyer disposition.
• Agent or queue identifier.
• CRM lead, contact, opportunity, appointment, sale, enrollment, or case identifier.
• Conversion event.
• Buyer feedback reason.
• Manual review note.

These records answer different questions.

A recording can help establish what was said during the recorded segment. It does not prove which creative the caller saw or why the route was selected. A CRM disposition can show what the buyer recorded. It does not prove the upstream source or automatically override telephony facts.

The governance issues around recording evidence are covered in call recordings, consent, and QA.

15. Qualification, conversion, duplicate, dispute, adjustment, billing, and payout events

The final stage interprets the call under the applicable commercial rules.

The trace should preserve separate events for:

• Qualification result.
• Buyer billability.
• Publisher payability.
• CPA conversion, where applicable.
• Duplicate decision and lookback rule.
• Dispute creation and reason.
• Evidence reviewed.
• Dispute decision.
• Credit, reversal, or adjustment.
• Buyer invoice batch and line reference.
• Publisher payout batch and line reference.
• Later payment or settlement state.

These statuses should never be collapsed.

A call can route without connecting. It can connect without qualifying. It can qualify for buyer billing under one rule while not yet becoming payable under a separate publisher rule. It can be initially billable and later adjusted after a valid dispute. It can be invoiced without the invoice being paid.

The foundational distinctions are explained in the difference between a routed, qualified, and billable call.

No single artifact proves the whole journey

A strong investigation uses several records together and states what each contributes.

Consider these common artifacts:

• Creative archive: establishes the reviewed or captured message, but may not prove the consumer saw that exact version.
• Web session: can connect a visit to a tracking event, but cookies, browser restrictions, shared numbers, or session loss can weaken the match.
• Consent certificate: can preserve a disclosure and action, but must match the correct consumer, seller, purpose, and event.
• Ping log: proves a request reached the routing system, not that the live call arrived.
• Bid response: shows a buyer response at a moment in time, not later connection or conversion.
• Reservation: shows an intended route, not necessarily a completed bridge.
• Telephony record: establishes provider-observed call events, not the consumer’s earlier advertising experience.
• Recording: captures audio for a permitted segment, not unrecorded events or upstream routing logic.
• CRM disposition: shows the buyer’s downstream record, which may be late, incomplete, duplicated, or mismatched.
• Invoice line: establishes a financial assertion, not necessarily the evidence supporting it.
• Payout line: shows publisher financial treatment, which may differ from buyer billing.

The investigator connects evidence without overstating certainty.

Common provenance breaks

Call provenance usually fails at the joins between systems.

Source-label drift

A publisher changes a source label, combines unrelated traffic, or reuses an old identifier for a changed consumer journey. Historical performance can no longer be compared cleanly.

Unversioned creatives and rules

The operation stores only the current page, script, qualification threshold, or duplicate policy. A later investigation silently applies today’s configuration to yesterday’s call.

Shared tracking numbers without session context

A single number is used across domains, creatives, or channels. The call can be attributed only broadly, but reporting presents a precise source match.

Missing or inconsistent identifiers

The publisher request ID, routing call ID, telephony provider ID, and buyer CRM ID do not travel together. Teams resort to matching by time and phone number, producing ambiguous joins.

Time-zone and clock disagreement

One system records UTC, another local time, and another a delayed processing timestamp. Events appear out of order unless the trace preserves both occurrence and receipt times with explicit time zones.

Lost webhooks or incomplete retries

The telephony or conversion provider sent an event, but the receiving system failed before durable processing. A retry may create a duplicate, or the event may never arrive.

Generic dispositions and reason codes

“Rejected,” “bad call,” “not qualified,” or “duplicate” gives no rule, evidence, or owner. The status exists, but the explanation does not.

Manual adjustments outside the call record

Finance changes an invoice or payout in a spreadsheet without linking the adjustment to the call, reviewer, reason, and approval.

Retention that removes a critical link

A recording, raw response, creative, or consent artifact is deleted before a dispute or investigation begins. Keeping everything forever creates its own privacy and security problems; deleting without a purpose-based policy creates an evidentiary gap.

Overexposed data

The operation solves traceability by exposing raw caller identifiers, private destinations, recordings, internal prices, or publisher methods too broadly. That is not mature provenance. It is uncontrolled access.

Three hypothetical investigations

Investigation 1: “The caller expected something we do not offer”

A buyer marks a call as misleading traffic.

The recording confirms the caller expected a benefit the buyer does not provide. That establishes the expectation during the call, but not its source.

The trace then connects the call to a session, tracking number, landing-page version, and creative. The reviewed advertisement was accurate, but a later dynamic headline variant was not included in the approval record. The best-supported conclusion is that the consumer expectation likely came from an unreviewed creative variation.

The result may justify pausing that variation or source. It does not prove every call from the publisher is misleading.

Investigation 2: “The buyer never received the call”

A publisher sees an accepted ping and expects payment. The buyer says no agent received the caller.

The trace shows an accepted buyer response and valid reservation. The live call arrived after the reservation expired, so the system did not reveal the protected destination or create a buyer leg.

The ping was successful. The buyer call never existed.

That is different from buyer no-answer, destination failure, or a short connected call. The remedy may involve publisher delivery latency or reservation timing, not buyer staffing.

Investigation 3: “Why did the invoice and payout report change?”

A call connected and initially met a duration threshold. It appeared in a preliminary dashboard as qualified.

Later, a duplicate review linked it to an earlier caller under the campaign’s lookback rule. A dispute was opened, reviewed, and approved. Finance issued an adjustment before finalizing the buyer invoice and publisher payout batch.

The preliminary operational state and final financial state are both real. The provenance trace should show the transition instead of rewriting the original call as though it never qualified.

This is also why source-level reporting matters for publishers: publishers need source-specific outcomes and reason codes, while provenance preserves the deeper call-level chain behind those reports.

Record-design principles for usable call provenance

Use stable internal identifiers

Create durable identifiers for the call, request, reservation, source, target, rule version, dispute, and financial event. Treat raw phone numbers as sensitive attributes, not the primary database key for every join.

Separate facts, decisions, and financial interpretations

A telephony completion is a fact reported by a provider. A qualification result is a decision under a rule. A billable amount is a financial interpretation. Store them as related but distinct events.

Version the things that can change

Version creatives, landing pages, disclosures, consent language, routing policies, source approvals, target settings, qualification formulas, duplicate rules, and commercial terms. Preserve effective times.

Prefer additive corrections over silent rewriting

When appropriate, keep the original event and add a correction, reversal, dispute decision, or adjustment. A clean history can explain why the final state differs from the initial state.

This does not mean every database must be technically immutable. It means material history should not disappear merely because a current-state field changed.

Record reason codes with human context

Use structured reason codes for reporting and automation, then allow a scoped explanatory note where judgment was involved. Avoid free text as the only evidence, but do not pretend every investigation fits one code.

Preserve occurrence time and processing time

An event may occur at one time and reach the system later. Store explicit time zones and both timestamps where delay matters.

Make uncertainty visible

A provenance system should be able to say:

• Exact match.
• Probable match.
• Ambiguous match.
• Unmatched.
• Evidence unavailable.
• Conflicting records.
• Pending investigation.

Forcing every call into a confident answer destroys trust when the evidence is weak.

Minimize data and scope access

The FTC’s Start with Security guide advises businesses to understand what personal information they hold, keep only what they need, restrict access on a need-to-know basis, and dispose of information when the legitimate need ends. NIST’s SP 800-53 control catalog similarly organizes security and privacy controls around areas including access control, audit and accountability, and personally identifiable information processing.

For call provenance, that means:

• Partner-facing IDs instead of raw internal identifiers where possible.
• Masked caller data in routine views.
• Recording access limited by role and purpose.
• Protected buyer destinations.
• Publisher methods disclosed only to the extent needed for review.
• Separate permissions for viewing, exporting, and downloading.
• Purpose-based retention and legal-hold procedures.
• Audit records for sensitive access and administrative changes.

Design retention by data type and purpose

There is no universal retention period for every call artifact.

Different artifacts carry different legal, contractual, operational, and privacy considerations.

Retention should account for:

• Applicable law.
• Contract terms.
• Tax and accounting needs.
• Dispute windows.
• Regulatory examination risk.
• Legal holds.
• Security exposure.
• Data-subject rights where applicable.
• Whether a less sensitive derived record can remain after raw data is removed.

Reconcile across systems instead of declaring one universal truth

Define which system is authoritative for each fact.

For example:

• The creative archive may be authoritative for approved versions.
• The routing system may be authoritative for eligibility and selection events.
• The telephony provider may be authoritative for provider-observed leg events.
• The buyer CRM may be authoritative for the buyer’s recorded sales outcome.
• The finance ledger may be authoritative for posted adjustments and batch inclusion.

Then create exception workflows for conflicts. Authority by field is more defensible than saying one platform is the truth for everything.

What buyers should expect from provenance

A serious buyer should be able to receive enough information to understand:

• Which reviewed source reference produced the call.
• What broad acquisition method and call type applied.
• Whether the source was enabled for the target.
• Why the target was eligible.
• Whether the call routed and connected.
• Which qualification rule applied.
• What buyer-side outcome was received.
• Why the call was billed, excluded, disputed, or adjusted.
• Which record supports an invoice line.

The buyer should not assume provenance creates unrestricted access to publisher identities, media accounts, sub-publisher relationships, proprietary methods, publisher payouts, or other buyers’ bids.

Buyer feedback is also part of provenance. If dispositions arrive late, use changing definitions, or cannot be joined to calls, the buyer weakens the shared record.

What publishers should expect from provenance

A serious publisher should be able to understand:

• Which source and sub-source produced the opportunity.
• Whether the request was accepted into the routing path.
• Why it received a bid, no bid, rejection, or timeout.
• Whether the live call matched the expected route.
• Whether it connected.
• Which publisher qualification and payout terms applied.
• Why it became payable, non-payable, disputed, held, or adjusted.
• Which payout line reflects the final result.

The publisher should not assume provenance entitles it to private buyer destinations, buyer price, margin, internal staffing details, or confidential buyer CRM information.

Publishers also carry responsibilities. Stable source labels, accurate call-type representation, retained creative versions, consistent request IDs, and timely cooperation during investigations are necessary links in the chain.

How Dependable Calls is approaching call provenance

Dependable Calls is being built around source-level accountability, controlled routing, explainable financial records, and scoped transparency.

The current software implementation includes several important building blocks:

• Trusted tracking-key resolution that connects a publisher assignment to a campaign and eligible buyer paths.
• Call and event records.
• Buyer eligibility evaluation, normalized bid responses, and distinct failure outcomes.
• Single-use route reservations that protect buyer destinations.
• Optional caller-identifier matching.
• Telephony bridging and status callbacks.
• Recording metadata where recording is enabled and permitted.
• Frozen financial inputs, qualification logic, ledger entries, invoice exports, payout exports, disputes, and adjustments.
• Audit and role-based access foundations.

Those components are implemented in code and substantially covered by automated tests. They should not be described as proof that every provenance link is already exposed in every portal, used consistently in every live workflow, or validated under production traffic.

The platform remains in launch hardening. Live telephony certification, a live campaign, and real-load validation remain important gates. Portal presentation, identifier continuity, PII masking, status semantics, and partner-safe reason codes require continued review as the system moves from implemented workflows to validated operations.

Current operating work also involves reconciliation across existing call, reporting, billing, and payout systems. That means the practical provenance problem is not solved merely because a unified data model exists in the application. Live procedures, partner integrations, exception handling, and financial close must prove that the record chain works under real conditions.

The goal is to make it harder for a call to become an unexplained row, unsupported charge, untraceable payout decision, or vague source complaint.

Call-provenance checklist

For a representative call, ask whether the operation can produce or explain:

Consumer and source

• Publisher and operating entity.
• Stable source and sub-source reference.
• Campaign, domain, brand, channel, and acquisition method.
• Creative and landing-page version.
• Material claims and disclosures.
• Tracking number, session, or request identifier.
• Applicable permission or consent evidence and its scope.

Routing and telephony

• Publisher ping or inbound event.
• Authentication and trusted campaign resolution.
• Targets considered and excluded.
• Bid responses, failures, and rejection reasons.
• Routing-policy and commercial-rule versions.
• Reservation and selected target reference.
• Caller or request matching result.
• Inbound and buyer-leg identifiers.
• Ringing, answer, bridge, completion, and duration events.
• Protected destination handling.

Buyer outcome and quality

• Recording policy and metadata where applicable.
• QA findings with reviewer and version context.
• Buyer disposition and CRM identifier.
• Conversion event and definition where applicable.
• Missing, delayed, or conflicting buyer feedback.

Finance and governance

• Qualification, billability, and payability kept distinct.
• Duplicate rule and result.
• Dispute, evidence, decision, and adjustment history.
• Buyer invoice and publisher payout references.
• Access controls and sensitive-field masking.
• Data-type-specific retention and legal-hold handling.
• Audit history for material changes and sensitive access.
• Explicit notation of missing or uncertain links.

A checklist cannot guarantee that a call is compliant, valuable, or payable. It can reveal whether the operation has enough connected evidence to investigate those questions responsibly.

The practical standard

Good call provenance does not mean collecting every possible field, exposing every counterparty, or keeping every artifact forever.

It means preserving the right links.

The creative should connect to the source. The source should connect to the campaign. The call or request should connect to the routing decision. The routing decision should connect to the telephony event. The telephony event should connect to the buyer outcome. The applicable rules should connect to qualification. Adjustments should connect to disputes. Invoice and payout lines should connect to the call-level financial record.

When a link is missing, the system should say so.

When two systems disagree, the operation should preserve the disagreement and investigate it.

When the evidence supports only a probable match, the explanation should not pretend it is exact.

That is what it means to make a call explainable through a real record trace.
