jcoffey-dev ba2276aa1a Phase 4: real Tantivy per-tenant isolation (search/src/registry.rs, enterprise/internal/searchclient)
Closes the last named "isolation mechanism" gap: search.proto gains a
tenant_id field on SearchRequest; search/src/registry.rs's IndexRegistry
resolves it to an on-demand-opened, per-tenant Tantivy index (empty
tenant_id keeps today's single default index, so this is purely
additive); enterprise/internal/searchclient sets that field from the
authenticated request identity in ctx, mirroring chrunner's exact
fail-closed "never a parameter" shape. Wired into enterprise-api in
place of the shared api/searchclient.

Unlike the ClickHouse pieces from the previous two commits, this one is
genuinely verified end to end in this environment: Tantivy is an
embedded library, not a networked service, so both the Rust index
registry (cargo test, cargo clippy --all-targets -- -D warnings, both
clean) and the Go client (a real in-process gRPC server) could actually
run. registry.rs's tenant_index_is_isolated_from_default_and_other_tenants
seeds three real indices with the same term and confirms a tenant-scoped
search returns only that tenant's document -- item 3 of the isolation
design doc's verification plan, closed for real, not just written.

With both ClickHouse and Tantivy isolation now built, the single largest
remaining gap is no longer a missing mechanism: it's that nothing forces
or flags whether a deployment actually runs enterprise-api instead of
plain api, and that ingest itself has no tenant concept for either
storage engine (every record still lands in the one shared database/
index no matter what -- undesigned, not just unbuilt). Updated the
threat model, architecture doc, CLAUDE.md, and both READMEs accordingly.

// This file is a checklist, not a fully passing test suite -- it exists
// so the four adversarial probes /docs/phase-4-isolation-design.md's
// "Verification plan for this design specifically" section names for
// Phase 4 task 8 have a permanent, grep-able home in the test tree.
//
// Three of the four are no longer blocked:
//
// - Item 1 (fully-qualified cross-tenant raw SQL):
// enterprise/internal/tenantprovision/tenantprovision_test.go's
// TestProvisionedUserCannotReadOtherTenantDatabase (raw ClickHouse-user
// layer) and enterprise/internal/chrunner/chrunner_test.go's
// TestRegistryTenantCannotReadOtherTenantEvenViaRawSQL (the actual
// query-execution code path, via enterprise/cmd/enterprise-api).
// - Item 2 (system.query_log/system.tables/SHOW DATABASES):
// enterprise/internal/tenantprovision/tenantprovision_test.go's
// TestProvisionedUserCannotReadSystemTables.
// - Item 3 (Tantivy cross-tenant search): search/src/registry.rs's
// tenant_index_is_isolated_from_default_and_other_tenants (Rust, the
// actual per-tenant index registry) and enterprise/internal/
// searchclient/searchclient_test.go (the Go client that resolves
// tenant_id from request identity, wire-level verified against a
// real in-process gRPC server).
//
// Item 4 remains blocked, for the reason its Skip below states. Note the
// scope boundary all three closed items share: they prove *read*
// isolation given tenant-scoped data exists -- they do not prove
// ingest/write-path tenancy, which doesn't exist yet (every record
// ingest produces lands in the single shared ClickHouse database and
// Tantivy index regardless of tenant) -- see
// /docs/security/threat-model.md.
