traceability-generate

Python test traceability generator

go run ./tools/traceability-generate expands the rules in test/conformance/traceability-rules.json into a deterministic entry for each frozen Python test function. Every go:, py:, or ts: evidence reference must resolve to a real repository test declaration.

The rules distinguish evidence deliberately assigned to one case from tests that only support a Python test file as a group:

• supporting_evidence produces file-supporting entries and is not a parity claim.
• cases produces explicit case-specific entries.
• case_evidence is reserved for one-to-one templates containing {python_test}, such as retained host-adapter tests with identical names.

case_specific_evidence_minimum is a non-regression checkpoint and must equal the generated case-specific count. Raise it whenever new Python cases gain explicit evidence; do not lower it to make generation pass.

Use go run ./tools/traceability-generate -check to reject missing source tests, stale output, unknown rules, path traversal, and nonexistent evidence. The generated traceability.json is checked by go test as well as CI.
