 - **Lost coverage is named, not hidden**: when a deleted test was the last test of a file, the line says `coverage removed: <file> has no remaining test` and the detail adds `M subject(s) lost their last test`. A modified file whose only test the branch deleted still fails PREGATE_NO_LANE.
 
 ### Changed
-- Only removed tests are waived. These still fail PREGATE_NO_LANE until a test or a `dependencies` entry covers them: any removed non-test path, a renamed source file's old name included; a removed test that remaining code imports; a deleted or renamed Go or Ruby test (it may define helpers its package still uses); and a deleted test whose merge-base text cannot be read (a symlink, invalid UTF-8, over 1 MiB). A remaining test that reads a deleted file or directory is still selected.

 ### Gate integrity
 - New `test/pregate-removed-paths.test.ts` (47 cases) covers the waived tests and the fail-closed negative controls; no existing test, threshold or allowlist changed.
