jcoffey-dev 088677643f Close search's active-tenant write-routing gap with a polled allowlist
search/src/consumer.rs's write-routing (built last pass) had no active-
tenant check at all: IndexRegistry.resolve() would open-or-create an
index directory for any syntactically-valid tenant_id, active or not --
unlike ClickHouse's chwriter.Registry (an active-tenants-only snapshot
built at enterprise-ingest startup) or the read side (gated by
searchclient.TenantChecker, a direct rbacstore query). search is AGPL
core with no Postgres access and no enterprise/ import allowed, so it
needed a network boundary instead -- the same shape ingest's
TenantResolver already uses against enterprise-auth, just Rust calling
Go instead of Go calling Go.

New GET /internal/active-tenants endpoint on enterprise-auth
(rbacstore.ListActiveTenantIDs + authhandler.handleActiveTenants),
gated on a RoleService Bearer credential -- server-to-server auth, the
same shape alerting presents to api, minted via the already-generic
enterprise-auth -mint-service-token search. search/src/tenants.rs's
ActiveTenantTracker polls it every 60s, blocking startup on the first
fetch succeeding (fail-closed cold start -- a control-plane outage at
boot must not silently accept every tenant_id) and keeping the last-
known-good set on any later refresh failure (a transient blip shouldn't
stop every tenant's indexing, only prevent the allowlist from growing/
shrinking until connectivity resumes). consumer.rs refuses any tagged
record whose tenant isn't in the polled set, before ever calling
resolve() -- IndexRegistry itself stays policy-free, matching the same
mechanism/policy split clickhousewriter.Writer vs. chwriter.Registry
already draws on the ClickHouse side.

Off unless ENTERPRISE_AUTH_URL/ENTERPRISE_AUTH_SERVICE_TOKEN are both
set (search/src/config.rs rejects exactly one being set) -- every
existing deployment is unaffected.

Verified with real HTTP round trips in this environment: tenants.rs's
tests exercise real reqwest requests (actual Authorization: Bearer
header, actual JSON parsing) against a hand-rolled dependency-free TCP
test server, including both fail-closed paths (rejected first fetch,
unreachable server). authhandler's new tests cover the credential-kind
distinction this endpoint exists to enforce -- a real human session,
even for a genuine Owner, must not satisfy a check meant for a service
identity.

One asymmetry remains, disclosed rather than fixed: chwriter.Registry's
snapshot still never refreshes (stale until enterprise-ingest restarts),
while ActiveTenantTracker's 60s poll gives Tantivy a materially tighter
staleness window. Neither is a live per-write check -- that would mean
a database/HTTP round trip per record, a throughput cost neither
implementation accepts -- so both have some staleness window by design;
the gap between the two windows is what's disclosed, not a claim either
is fully live.
