jcoffey-dev bdd42e06f6 Build per-tenant Tantivy write-routing, closing the last ingest write gap
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tenant that's no longer active.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.

jcoffey-dev 1de77b969f 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.

jcoffey-dev 17fdc212c2 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.

jcoffey-dev 823f5d48d1 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.

jcoffey-dev 08a90a27aa 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.

jcoffey-dev 3037b31b0f Phase 4: Helm chart enforces api vs enterprise-api, closing the deployment-topology gap
deploy/helm/sentry/templates/api.yaml and the new enterprise-api.yaml
are mutually exclusive, gated on opposite sides of the same
enterprise.enabled flag -- exactly one renders, both as a Deployment+
Service named {{ .Release.Name }}-api on port 8080, so every consumer
(alerting's API_QUERY_URL, web's build args) needs zero conditional
logic of its own. This is the concrete fix for what the threat model
named as the single largest remaining gap once both storage engines'
isolation mechanisms were built: previously nothing forced or flagged
whether a deployment ran the tenant-isolated binary. Now the same flag
that turns on RBAC/audit/SSO also chooses the query binary.

Verified by parsing (not eyeballing) helm template's rendered output
under both value sets: exactly one sentry-api Deployment/Service either
way, with the right image, and kubeconform -strict clean against the
real Kubernetes 1.31 schema. Not applied to a live cluster (still no
cluster in this environment) -- docker-compose.yml also still runs
plain api unconditionally, so this enforcement is Helm-only for now.

Updated the threat model, architecture doc, CLAUDE.md, and deploy/
READMEs to reflect this and to name what's left: ingest has no tenant
concept for either storage engine (undesigned), and the Tenant CRD
(deploy/operator) and enterprise-api -provision-tenant are still two
separate, unreconciled provisioning mechanisms.

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.
2026-08-13 23:16:22 -07:00
jcoffey-dev 1fab02abd5 Phase 4: real OIDC human login (enterprise/internal/loginhandler)
Closes the other major named gap from this phase: until now, there was
no way for a human to actually log in -- only /alerting's RoleService
credential could be minted. GET /auth/oidc/login and GET
/auth/oidc/callback drive the real coreos/go-oidc flow already wired in
enterprise/internal/oidc: CSRF state in a short-lived cookie, code
exchange, ID token verification, upserting a users row, resolving
tenant/role from exactly one tenant_memberships row (refusing outright
on zero or more than one, rather than guessing), and issuing a real
session cookie.

Unlike everything else built this phase, this one is genuinely verified
end to end: the tests spin up coreos/go-oidc's own oidctest fake IdP,
which signs real RS256 ID tokens, and drive the full login->callback->
session-cookie round trip through actual signature verification -- no
live database or Docker needed, so nothing here is asserted without
having actually been run in this session. Also fixes a real bug caught
while wiring this into enterprise-auth's main.go: assigning a nil
*oidc.Provider to the handler's interface field would have produced a
non-nil interface wrapping a nil pointer (Go's classic typed-nil trap),
silently breaking the "OIDC not configured" no-op path -- New() now
takes the concrete pointer type and checks it before ever converting to
the interface, with a regression test pinning the fix down.

Still missing: SAML's equivalent (ACS endpoint), a tenant-picker UI for
multi-membership identities, and any admin UI to actually create a
tenant_memberships row (today that's manual SQL, documented in the
runbook's new bootstrap walkthrough).
2026-08-13 23:00:35 -07:00
jcoffey-dev 1d57e697b1 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.
2026-08-13 22:48:38 -07:00
jcoffey-dev 3eb0f4c589 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).
2026-08-13 22:16:59 -07:00
jcoffey-dev b6b092c912 Scaffold Phase 0: agent -> Redpanda -> ingest -> ClickHouse -> api -> web
End-to-end log pipeline for Linux hosts, per /docs/architecture.md:

- proto: shared gRPC contract (agent <-> ingest), Go bindings checked in
- agent: Rust, musl-targeted, journald/file sourcing, RFC5424 parser,
  mTLS gRPC client, no required config for the common case
- ingest: Go, single binary with --mode server|consumer|all; gRPC front
  end forwards to Redpanda unchanged, consumer normalizes and
  batch-writes to ClickHouse with at-least-once delivery
- storage: ClickHouse schema + a plain SQL-file migration runner
- api: minimal SELECT-only query endpoint, plain REST (not gRPC+gateway
  yet -- see api/README.md)
- web: SvelteKit static SPA, one query page
- transport: Redpanda compose + topic provisioning
- cli: sentryctl ping stub
- hack/dev-certs: throwaway CA + cert generation for local mTLS
