search/src/consumer.rs now resolves each record's tenant_id Kafka header through the same IndexRegistry the read side (search/src/registry.rs + enterprise/internal/searchclient) already used, and writes into that tenant's own index instead of always the default one. The periodic Tantivy commit now commits every tenant index that's actually seen a write (IndexRegistry::commit_all), not just the default index. Unlike ClickHouse, this needed no "second binary": Tantivy has no grant system to gate a commercially-licensed credential behind, so IndexRegistry already lived directly in this AGPL-core search binary -- there was never an import-boundary reason to split the write side into an enterprise/ binary the way chwriter/enterprise-ingest was for ClickHouse. Read and write simply share one registry. Because Tantivy is an embedded library, this is genuinely verified in this environment, not just written: registry.rs's commit_all_commits_default_and_every_opened_tenant_index writes into the default index plus two tenant indices, confirms nothing is searchable pre-commit, then confirms all three are post-commit. consumer.rs's tenant_id_from_headers is factored out as a small pure helper (mirroring ingest/consumer.tenantIDFromHeaders) with its own unit tests, plus a guard test against the "tenant_id" header-key literal drifting from the Go side's -- the same guard-test pattern ingest/cmd/ingest already used for its own two Go copies of the constant, now mirrored a third time across the language boundary. One gap is disclosed, not fixed, by this change: unlike chwriter.Registry (an active-tenants-only snapshot built at enterprise-ingest startup, so an unrecognized tenant_id is refused outright) and unlike the read side (gated by searchclient.TenantChecker), this consumer's registry.resolve() call has no active-tenant check at all -- search has no Postgres access to check tenant status against. A still-valid-but-should-be-revoked ingest credential can cause an index directory to be created for a tenant that's no longer active. Narrow blast radius (an orphan, isolated, empty index, not cross-tenant leakage, and only reachable with a real signed credential), but real -- see registry.rs's doc comment on resolve(). Closing it fully would mean giving search some way to learn which tenants are active without an enterprise/ import, which isn't designed yet. This closes the last of Phase 4's ingest write-routing gaps (ClickHouse was closed last commit). The one remaining gap in the whole phase is now the tenant-picker frontend page, deliberately deferred earlier in this phase as out of scope for this environment.
