Full dependency inventory across Rust/Go/npm plus Docker base images
and vendored assets (776 rows, 502 unique deps), classified against
AGPLv3 compatibility with real citations rather than assumptions.
enterprise/ relicensed from its commercial-license stub to AGPLv3,
matching core -- the one real flag (Redpanda's BSL 1.1) was evaluated
against primary sources and accepted as-is rather than triggering a
broker swap. CI enforcement wired up (.github/workflows/license-
compliance.yml, this repo's first CI workflow), a root LICENSE file
added, and every doc/comment referencing the old commercial-license
boundary updated to describe it as architectural only.

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.
