Build per-tenant ClickHouse write-routing for ingest (Tantivy still deferred)
ingest tags every record with a tenant_id Kafka header (built previously), but nothing consumed it to actually route the write. This closes that for ClickHouse: enterprise/cmd/enterprise-ingest (a second binary, mirroring enterprise-api) reuses ingest/consumer's own flush loop unchanged, with enterprise/internal/chwriter.Registry -- a per-tenant clickhousewriter.Writer registry -- swapped in as the writer. A batch pulled from the single shared Redpanda topic can mix records from many tenants, so WriteBatch groups by TenantID and dispatches each group to its own tenant's connection, fail- closed on an empty or unrecognized tenant_id. ingest/consumer and ingest/clickhousewriter move out of internal/ (same reason api/internal/* moved earlier this phase: enterprise/ can't import anything under another module's internal/). Their New() constructors now take small local Config structs instead of ingest/internal/config types, so enterprise/ doesn't need that import either. Building this surfaced a real bug: tenantprovision.ProvisionClickHouse only granted SELECT on a tenant's ClickHouse user, correct for chrunner's read-only use but not enough for chwriter reusing the same credential to write -- every real per-tenant write would have failed closed with a permission error. Fixed by widening the grant to SELECT, INSERT; no cross-tenant boundary is crossed by also allowing INSERT within a tenant's own database. Helm gates enterprise-ingest's Deployment on the same ingest.requireTenantCredential flag that already gates tag validation -- write-routing is meaningless without tagging already being required, so they're one decision, not two. docker-compose.yml's version is a disclosed, weaker approximation: it can't achieve Helm's genuine -mode=server/-mode=consumer split, so with the enterprise profile active both ingest and enterprise-ingest independently consume every message via different consumer groups -- harmless duplication for local verification only. Not built: Tantivy's independent Redpanda consumer (search/src/consumer.rs) still doesn't read the tenant_id header at all -- every record still lands in the one shared index regardless of tenant. Not run: the live-ClickHouse- gated tests (chwriter's cross-tenant routing test, tenantprovision's INSERT regression test) -- no Docker/database access in this environment; they're correct Go that has never executed, disclosed as such in docs/security/ threat-model.md and docs/phase-4-runbook.md §14. |

Unify the Tenant CRD with enterprise-api -provision-tenant (lightweight)
Closes a gap named across CLAUDE.md/docs/architecture.md/deploy/README.md
since early Phase 4: the operator's Tenant CRD and -provision-tenant
were two disconnected mechanisms. The operator's reconciler generated a
K8s Secret with a locally-generated random password that authenticated
against nothing (nothing ever called ClickHouse to create a matching
user), and unconditionally claimed status.phase=Active the moment a
Tenant object existed -- actively misleading, not just incomplete.
Two unification shapes were considered (surfaced to the user via
AskUserQuestion, given the real difference in blast radius): the
operator's reconcile loop becoming a second real actor (new Postgres +
ClickHouse admin credentials flowing into the K8s controller, plus real
reconcile-loop idempotency/retry design for an inherently one-shot
external side effect), or keeping -provision-tenant as the sole real
actor and having it also sync its result into the CRD. Went with the
lighter option.
enterprise/internal/tenantcrd (new): a Syncer using the K8s dynamic
client (unstructured.Unstructured + a GroupVersionResource, not
deploy/operator's typed Tenant struct -- avoids a cross-module Go
dependency between two independently-versioned modules for one type).
Upserts the Tenant object, creates/updates a Secret with the *real*
ClickHouse credentials owned by that Tenant via an OwnerReference, then
patches status.{clickHouseDatabaseName,clickHouseSecretRef,
tantivyIndexPath}. Idempotent and safe to retry: never rotates a
credential across a re-sync, never overwrites a pre-existing
spec.displayName a human/GitOps process set.
cmd/enterprise-api/main.go's runProvisionTenant calls Sync when
TENANT_CRD_NAMESPACE is set (empty = no-op, same shape as every other
optional dependency in this codebase). Its "already active" refusal is
now split: ClickHouse re-provisioning is still refused (rotating a live
credential would break every open connection for no benefit), but CR
sync alone is now retryable using the credentials already on file in
rbacstore -- needed for retrying a previously-failed sync, or
backfilling CR sync for a tenant provisioned before this existed.
deploy/operator's reconciler rewritten to match: it never claims
PhaseActive on its own initiative anymore, only once
status.ClickHouseDatabaseName is non-empty (the field -provision-tenant,
and only -provision-tenant, sets). Phase is now a pure function of
{spec.suspended, status.ClickHouseDatabaseName != ""} recomputed every
reconcile, not toggled in place -- fixes a related bug the old code
would have hit once suspension was involved: un-suspending an
already-provisioned tenant needs to return straight to Active, which
isn't derivable from "last observed phase was Suspended" alone. The
reconciler no longer creates or manages any Secret, dropped its
`secrets` RBAC grant entirely, and gained zero new dependencies.
Helm chart: enterprise-api gets its own ServiceAccount/Role/RoleBinding
(get/list/create tenants, get/update/patch tenants/status, get/create/
update secrets -- least-privilege, scoped to the release namespace, not
a ClusterRole) and a TENANT_CRD_NAMESPACE env var, both gated on
tenantOperator.enabled. tenant-operator's ClusterRole loses the
secrets grant it no longer needs.
Verified in this environment: enterprise/internal/tenantcrd's tests run
against k8s.io/client-go's fake dynamic + typed clientsets (real client
library, fake transport, no cluster needed); deploy/operator's rewritten
tenant_controller_test.go runs against controller-runtime's fake
client, including new regression tests for the "must not claim Active
without confirmation" and "un-suspending returns to Active, not
Provisioning" properties; helm template + parsing the rendered YAML
confirms the RBAC split renders exactly as designed under both
tenantOperator.enabled=true/false. Not verified: an actual
-provision-tenant run against a real cluster with the operator watching
(no live cluster in this environment, same disclosed limitation as the
rest of /deploy). Docs updated in lockstep: CLAUDE.md, docs/architecture.md,
deploy/README.md, deploy/helm/sentry/README.md (including a corrected
"Trying the two-tenant example" walkthrough), phase-4-runbook.md (new
§11), enterprise/README.md. Also fixed two unrelated stale claims found
along the way: docs/architecture.md still said docker-compose.yml ran
plain api unconditionally (fixed in an earlier commit, doc not updated
then), and enterprise-api's own main.go doc comment still said Helm/
docker-compose wiring wasn't built yet.

Build SAML login (enterprise/internal/loginhandler), mirroring OIDC
Adds GET /auth/saml/login + POST /auth/saml/acs alongside the existing OIDC pair, both converging on the same upsert-user/resolve-tenant/ issue-session path. loginhandler.New now takes an optional *saml.ServiceProvider, RegisterRoutes registers each protocol's routes independently so either, both, or neither can be configured. SAML's replay/unsolicited-response defense (InResponseTo, standing in for OIDC's state) is carried via a SameSite=None sentry_saml_request cookie -- None because the ACS endpoint receives a cross-site POST from the IdP's origin, which SameSite=Lax cookies are never sent on. enterprise-auth's main.go now fetches+parses SAML_IDP_METADATA_URL at startup (samlsp.FetchMetadata) and wires the result through. Verified to the same bar as OIDC: a real fake IdP (crewjam/saml/samlidp, genuine XML signing/verification) drives the full login->ACS->session-cookie round trip and negative paths (bad InResponseTo, missing request cookie, missing email/NameID, no/multiple tenant memberships), all in loginhandler/saml_test.go, no Docker needed. The login-form HTML is bypassed by pre-seeding a saml.Session directly into samlidp's session store and presenting the matching `session` cookie -- an IdP-supported shortcut (confirmed by reading GetSession), the same "skip the UI, keep the crypto real" approach oidctest gave the OIDC tests. Writing that test caught two real bugs in internal/saml.ParseResponse, both fixed here: it never called r.ParseForm() before reading the POSTed SAMLResponse field, so every real ACS POST would have silently decoded an empty response; and its email-attribute matching missed urn:oid:0.9.2342.19200300.100.1.3 (the standard LDAP "mail" OID), which is what an IdP sends by default absent an explicit AttributeConsumingService request for "email" -- exactly what samlidp's own DefaultAssertionMaker does, and plausibly what real IdPs' default SAML app templates do too. Docs (CLAUDE.md, threat-model.md, architecture.md, enterprise/README.md, phase-4-runbook.md, docker-compose.yml's enterprise-auth comment) updated in lockstep: SAML login moves from "protocol mechanics only" to "built, verified with a real fake IdP, not yet tried against a real external IdP or a running enterprise-auth container" -- the same disclosed gap OIDC already carried. |

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. |

Phase 4: real per-tenant ClickHouse isolation via a new enterprise-api binary
Closes the threat model's headline finding for the SQL query path:
enterprise/internal/tenantprovision does real CREATE DATABASE/USER/GRANT
against ClickHouse, and enterprise/internal/chrunner is a per-tenant
connection registry implementing api's SQLRunner interface, resolving
the tenant from the authenticated request identity -- never a
caller-suppliable parameter. Both are wired into a new binary,
enterprise/cmd/enterprise-api, alongside the unchanged single-tenant
api/cmd/api, since AGPL core can never import enterprise/ and Go's own
internal/ package visibility rules meant enterprise/ couldn't implement
core's SQLRunner interface without importing the package that defines
it. That required moving api/internal/{authz,queryapi,dashboards,
querylang/executor,searchclient,httpserver} out of internal/ -- the
minimal set enterprise-api needs to import; querylang's compiler
internals (planner/lexer/parser/ast/ir) and api's own config stay
internal, since nothing outside api needs them directly.
Also finally wires enterprise/internal/audit into queryapi.AuditLogger
(nil since Phase 4 task 4) via a new adapter, and adds live-ClickHouse
integration tests for two of the four adversarial probes named in
docs/phase-4-isolation-design.md's verification plan.
Corrected several overclaims in the docs while writing this up: an
earlier claim that rbacstore's CRUD was "verified against a live
Postgres" was never actually true in this environment (only
internal/audit was, earlier in this phase, before Docker access was
lost) -- threat-model.md, phase-4-runbook.md, CLAUDE.md, and
enterprise/README.md all now distinguish "a real integration test
exists" from "this was confirmed against a live database."
Still not built: Tantivy/free-text tenant isolation
(enterprise/internal/searchclient), and any deployment-topology
mechanism that actually routes traffic to enterprise-api instead of
plain api -- both binaries exist side by side today with nothing
enforcing or flagging which one a deployment runs.

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). |
