In DNS-01 mode, the parent's wildcard Certificate now covers every inheriting child tenant's apex (`<child-apex>` + `*.<child-apex>` as additional SANs) and the parent Gateway grows one wildcard HTTPS listener per child apex referencing the same Certificate. Without the expansion, a child route hostname like `harbor.alice.example.org` fails to match the parent's listeners — `*.example.org` is a single- label wildcard and `alice.example.org` is two labels deep — and the TLS handshake fails the SNI check because the parent cert never listed the child apex. The controller discovers inheriting children by listing namespaces labelled `namespace.cozystack.io/gateway = <tgw.Namespace>` (the existing inheritance contract from Stage 1/3) and reading their `namespace.cozystack.io/host` label, which apps/tenant chart writes to the child apex. Children with no host label are skipped (defensive); a child host equal to the parent apex is deduplicated (cert-manager rejects duplicate dnsNames). HTTP-01 mode is unchanged — its per-listener / per-cert flow already handles child hostnames without any wildcard. Listener naming: `https-child-<first-label>-<8-hex>`, where the hex suffix is sha256(child-apex)[:8] so two children whose first DNS label collides produce distinct listener names. Cap: Gateway API hard-caps spec.listeners at 64 entries. The parent uses 3 slots (http + https + https-apex) leaving ~61 wildcard children per parent. Operators whose subtree fans out beyond that must run the high-fanout branch on its own Gateway via tenant.spec.gateway=true. Tests (TDD red→green): * TestReconcile_DNS01WildcardCertCoversInheritingChildApexes pins the SAN list contains both `<child-apex>` and `*.<child-apex>`. * TestReconcile_DNS01WildcardCertDeduplicatesChildApexEqualToParent pins the dedupe path (child host == parent apex). * TestReconcile_HTTP01WildcardCertNeverRendered pins the inverse: HTTP-01 mode never renders a wildcard Certificate. * TestReconcile_DNS01GatewayHasListenerPerChildApex pins the listener-side expansion (one `*.<child-apex>` listener per inheriting tenant, all referencing the parent's wildcard cert).
