test(pril): make C4 tracked-file assertion bite on its own (review sa…

…lvage)

Independent-review finding (salvaged from a session-limit-killed reviewer, then verified by mutation probe): the tracked-but-ignore-matching assertion ran against a changed-list that also carried an independently-blocking file, so it would have passed even if tracked files were wrongly exempted. Now a single-file tracked-only list decides purely on the tracked/untracked split, plus a roundtrip assertion (untracked again -> exempt again).

Mutation probes: disabling only the tracked-split still blocks (git check-ignore itself excludes tracked files — independent second defense); unconditional exemption makes BOTH assertions fail. Reverted after probe.

Summary by Sourcery

Tests:

• Adjust the C4 tracked-file ignore test to use a single tracked-only changed-file list and add a roundtrip assertion verifying exemption after returning to untracked.

Reviewer's Guide

This PR strengthens the C4 runtime integrity test by ensuring the tracked-but-ignore-matching assertion is exercised in isolation on a single-file changed list and adds a roundtrip check that the same path becomes exempt again when untracked, directly validating the tracked/untracked split behavior.

File-Level Changes

Change	Details	Files
Make the C4 tracked-but-ignore-matching assertion operate on a single tracked file and add a roundtrip assertion to verify behavior when the file is untracked again.	Create a dedicated changed-files list containing only the tracked ignore-matching path to ensure the assertion fails if tracked files are ever wrongly exempted. Update the tracked-but-ignore-matching assertion to use the new single-file changed list instead of a list that also includes another independently-blocking file. Add a new assertion that, after removing the file from the index, the same single-file changed list is exempt again, proving that the decision is based on tracked vs untracked status rather than the path itself.	config/claude/tests/test_runtime_integrity_layer.sh
