# PR evidence checklist [#pr-evidence-checklist]

Use this checklist before you request review on a tax behaviour or public
contract change.

## Required evidence [#required-evidence]

* Source citations for every changed fact, rule, parameter table, calculator
  or tax year.
* Owning package for each changed schema, type, branded ID, service tag, layer
  and tagged error.
* Golden tests or regression tests for changed tax results.
* Type tests for public SDK input, output or descriptor changes.
* API compatibility tests for HTTP request, response, error or metadata
  changes.
* SDK compatibility tests for SDK helper or schema export changes.
* Graph, trace or ledger evidence when rule dependencies or outputs change.
* Release-impact notes that say whether behaviour is patch, minor, major or
  docs-only.
* Changeset path, or a no-Changeset rationale for docs-only or app-internal
  work.
* `bun run verification` result.
* `bun run changeset status --verbose` result.
