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. |

Give ingest a real tenant identity (write-routing deferred, disclosed)
Ingest tenant-awareness was named "undesigned, not just unbuilt" across CLAUDE.md/threat-model.md/the runbook since early Phase 4 -- the last major standing gap. Scoping was agreed via AskUserQuestion: a config-supplied tenant_id + shared-secret token ingest validates (smaller real implementation, no new PKI), over per-tenant mTLS certs. This change builds that identity mechanism end to end and attaches it to every record at the point it enters the system; it deliberately does NOT build per-tenant write-routing for ClickHouse or Tantivy -- that's real, separately-scoped follow-up work, disclosed explicitly everywhere this was previously called undesigned, not silently left half-done. New pieces: - metadata/migrations/0034 + enterprise/internal/rbacstore/ ingest_credentials.go: a per-tenant bearer credential, only its SHA-256 hash ever persisted (same reasoning a password gets hashed, not stored raw) -- CreateIngestCredential returns the plaintext exactly once, ValidateIngestCredential/RevokeIngestCredential/ ListIngestCredentialsForTenant round it out. - enterprise-auth gains -create-ingest-credential-tenant/ -list-ingest-credentials-tenant/-revoke-ingest-credential (same offline-operator-flag shape as every other credential-minting flag in this binary) and a new POST /internal/authorize-ingest endpoint (internal/authhandler) validating a presented token and resolving its tenant -- a genuinely different credential type from session-backed /internal/authorize, so it doesn't touch session.Manager at all. - ingest (AGPL core) gains an optional TenantResolver (internal/grpcserver, nil by default) and its HTTP client implementation (internal/tenantresolver.HTTPResolver) -- a plain HTTP call to enterprise-auth's new endpoint, never an enterprise/ import, same "network boundary, not import boundary" shape api/authz.HTTPAuthorizer already uses for the query path. PushBatch now requires an `authorization: Bearer <token>` gRPC metadata entry once a resolver is configured, fails the whole batch closed on a missing/invalid credential (never falls back to "no tenant"), and attaches the resolved tenant ID to every record as a `tenant_id` Kafka message header before producing it. Verified with real round trips at every layer, no Docker needed: rbacstore's credential CRUD (skip-gated on live Postgres, same as every other rbacstore integration test this phase), authhandler's new endpoint (real HTTP via httptest, including the regression test that a session token must not validate as an ingest credential), tenantresolver (real HTTP client against httptest, same pattern as authz.HTTPAuthorizer's own tests), and grpcserver's PushBatch (fake resolver/producer -- no resolver leaves messages unchanged, a configured resolver attaches the right header or fails closed on a bad/missing token). Helm: ingest.requireTenantCredential (default false) is a deliberate, separate opt-in from enterprise.enabled -- turning ENTERPRISE_AUTH_URL on for ingest requires every agent to already hold a credential or be refused outright, so it must not default on just because enterprise.enabled does (same reasoning api.yaml's ENTERPRISE_AUTH_URL isn't tied to enterprise.enabled directly either). docker-compose.yml leaves it unset, same as ever. Docs updated everywhere this was called "undesigned": CLAUDE.md, docs/architecture.md, docs/security/threat-model.md (including its summary table, now split into "identity: built" vs "write-routing: not yet"), docs/phase-4-runbook.md (new §13), enterprise/README.md. |

Phase 4: SSO scaffolding, RBAC enforcement, tenant-scoped dashboards, audit logging, K8s deployment
RBAC (api/internal/authz) is live on /query and /dashboards, backed by a new enterprise/ module (session issuance, audit logging, RBAC storage, OIDC/SAML protocol wiring) that core never imports -- only calls over HTTP. Found and fixed a real cross-tenant vulnerability in dashboards (no tenant_id filtering at all) while writing the threat model doc. Two things are explicitly NOT done, documented rather than hidden: tenant isolation for log data itself (/query still shares one ClickHouse connection and Tantivy index across every tenant -- RBAC controls who can query, not what a query can see), and human SSO login (protocol wiring exists, no HTTP handler calls it yet). See docs/security/threat-model.md and docs/phase-4-runbook.md. Also adds deploy/ (Go Operator + Helm chart, validated offline only -- no cluster was reachable in this environment). |
