Proof map

Six records. Six different jobs.

Evidence becomes unreliable when unlike records are collapsed into one badge. Keep the question, object, issuer, scope, and date attached.

FACILITY AUDIT

Supports

How a named site performed against a defined protocol on a defined date.

Do not overread it

It does not automatically identify the origin of every hide or certify every finished product.

CHAIN OF CUSTODY

Supports

How material or data moved through specified organizations, transactions, lots, or models.

Do not overread it

The boundary, model, mixing rules, tiers, and unresolved gaps must remain visible.

TEST REPORT

Supports

What a named laboratory found in a specific sample using a stated method.

Do not overread it

A sample result is not a permanent guarantee for every production lot or unrelated property.

POLICY

Supports

What an organization says it requires, prohibits, or intends to do.

Do not overread it

A policy is not evidence that each supplier, transaction, or product satisfied it.

TRANSACTION RECORD

Supports

What a document says moved between named parties at a particular time.

Do not overread it

Check identifiers, units, dates, product match, and continuity with preceding and following records.

CERTIFICATE OR CLAIM

Supports

A conclusion issued under a defined program, standard, owner, and validity period.

Do not overread it

Read the issuer, status, scope, subject, standard version, exceptions, and current validity.

Minimum evidence line

Object + source + scope + date + limitation.

Object: the product, lot, material, facility, transaction, or organization at issue.

Source: who created or controls the record.

Scope: the question, standard, site, process, tier, geography, and period actually covered.

Limitation: every material exclusion, gap, assumption, or unresolved link.
