One pinned run identity
Each run binds the fixture, engine, standard pack, France pack, test case, and provider adapter identities used for that exact execution.
Product
A test rig for integration teams, not an accounting system.
InvoiceRig helps engineering teams reproduce technical validation and provider sandbox observations around the same pinned run. It is not an invoice editor, legal archive, PA, or certification authority.
Layered outcomes
XML, syntax, EN 16931, France rules, and provider observations remain separate layers so a provider rejection cannot be mistaken for a validation failure, or vice versa.
Share-safe evidence
Operator exports are deliberately bounded to normalized outcomes, technical identities, rule identifiers, and evidence hashes rather than invoice content, credentials, or raw provider bodies.
