`codegraph affected` kept six regexes of its own — `.test.`, `.spec.`, `/tests/`… — so a Go `foo_test.go`, a Python `test_foo.py` or a JVM `FooTest.kt` beside the changed file was never reported, and "no tests affected" read as "no coverage". Use isTestPath from search/query-utils, the same predicate search and the MCP tools already rank by. Cherry-picked from danusha2345's upstream PR #1688 (commit 995b6f1f262564cafa6eb0b026b84fa4122f2cb0). Preserve main's CLI imports and Unreleased entries, and credit the contributor in the changelog. The default affected depth remains 5. Fixes #1507. Supersedes #1688. Verified on Linux with Node 22.19.0: npm run build; the Go fixture changes from no affected tests to math_test.go; matching and nonmatching custom filters still override. Vitest: 3 files, 36 tests passed, including the upstream Go/Python/Kotlin suite and affected path/dependency coverage. Co-authored-by: danusha2345 <ewidusoc498@gmail.com>

* `codegraph affected` recognises every ecosystem's test-file convention (#1507).

|
|
* The command used to carry its own six regexes — `.test.`, `.spec.`,
|
|
* `/tests/`… — so a Go `foo_test.go`, a Python `test_foo.py` or a JVM
|
|
* `FooTest.kt` beside the changed file was never reported, and "no tests
|
|
* affected" read as "no coverage". It now shares `isTestPath` with search and
|
|
* the MCP tools. Exercised end-to-end against the built binary.
