Tests reach a controller by URL, never by a call — MockMvc's
`perform(post("/owners/new"))`, Laravel's `$this->postJson('api/me')` — so
every controller those suites exercise read as untested: the viewer's
"No test reaches this" and explore's `tests:` line both walk callers.
petclinic's processCreationForm, hit three times by OwnerControllerTests,
said no test reached it.
A new synthesis pass (tier-synthesizer section 4, registered after the
cross-tier pass, gated on java / kotlin / php) reads test files only:
- Spring: MockMvc builders (with MockMvcRequestBuilders imported),
`request(HttpMethod.X, …)`, the Kotlin `mockMvc.get(…)` DSL,
WebTestClient `.get().uri(…)`, TestRestTemplate, RestAssured.
- Laravel: `$this->get/post/…Json(…)`, `->json('POST', …)`, `->call(…)`
on a chain rooted at `$this` that only calls methods (so
`$this->app->get('config')` is not a request); Pest's helpers where the
file imports Pest\Laravel; and a project's own verb-named helpers
(koel's getAs → jsonAs → `$this->json($method, $uri)`), recognised by
their body, never by name alone.
Paths are read as built — Spring `{var}` templates, PHP / Kotlin
interpolation and concatenation become holes — and matched with the
cross-tier pass's own route matcher (a hole fills a parameter, never a
literal). One `calls` edge per (test, route), `synthesizedBy:
'test-request'`. These edges are excluded from countIncomingEdges, so a
well-tested endpoint never becomes a hub the Steps walk refuses to enter.
Routes reached by a test: petclinic 16/17, realworld 18/19, BookStack
194/340, koel 105/134 (from 0 each). A random sample of edges checked
against the test source was all correct. The pass costs 86 ms on
BookStack and 68 ms on koel.
