Close the last tenant-isolation adversarial probe (mid-provisioning tenants)
Phase 4 task 8's verification plan named four adversarial probes; three were closed earlier this phase, the fourth (an evaluator tick, or any other caller, hitting a tenant that exists but hasn't reached the active+credentialed gate yet -- must be refused, not served) was still an explicitly-skipped stub in api/queryapi/tenant_isolation_gap_test.go. Investigating it found the two storage engines needed genuinely different treatment: - ClickHouse (enterprise/internal/chrunner) already had this property structurally, for free: Registry is built once at startup from rbacstore.ListProvisionedDataSources, which already filters to active+credentialed tenants only, so a mid-provisioning tenant is simply absent from the connection map. New test TestRegistryRefusesMidProvisioningTenant proves this without Docker -- an empty DataSource list never dials ClickHouse, so this genuinely runs in this environment, unlike every other test in that file. - Tantivy (search/src/registry.rs's IndexRegistry) was a real, different gap, not just an unverified assumption: it opens-or-creates an index for any syntactically-valid tenant_id on first request, because it's a separate process with no Postgres access and structurally can't know which tenants are actually provisioned. A query against a mid-provisioning tenant would have silently succeeded with zero results from a freshly-created empty index -- "ambient success" indistinguishable from "no matching logs," exactly the failure mode this item was worried about. Fixed the Tantivy gap with a new enterprise/internal/searchclient. TenantChecker interface (backed by a new rbacstore.TenantIsActive, implemented structurally, no new import edge needed), consulted before every gRPC call: Client.Search now refuses a non-active tenant before it ever reaches `search`. Dial's signature gained a required TenantChecker parameter; enterprise-api's main.go passes its existing rbacstore.Store (already satisfies the interface). Verified Docker-free via searchclient's existing real-in-process-gRPC-server test harness (TestSearchRefusesMidProvisioningTenant, plus TestSearchPropagatesTenantCheckerError for the fail-closed-on-error case) -- both genuinely run in this environment, same bar as the rest of the Tantivy isolation work. rbacstore.TenantIsActive itself has two new skip-gated live-Postgres tests (TestTenantIsActive, TestTenantIsActiveNonexistentTenant) -- disclosed as not run against a live database here, same gap as the rest of this phase's Postgres-backed pieces. api/queryapi/tenant_isolation_gap_test.go rewritten from a checklist with one skipped stub to a full accounting of all four now-closed probes. Docs updated in lockstep: CLAUDE.md, threat-model.md, phase-4-isolation-design.md (implementation note added after its original sign-off), phase-4-runbook.md (§9), enterprise/README.md. |

Enforce per-resource dashboard grants (RBAC matrix's own/granted qualifier)
api/dashboards' handler previously enforced only tenant-baseline role
(RoleEditor+), so any Editor could edit/delete any dashboard in their
tenant -- the matrix's "(own/granted)" qualifier was explicitly named
as unbuilt in this handler's own doc comment. This closes that gap.
New core interface api/dashboards.PermissionStore (nil-safe, same "not
wired == no-op" shape as authz.Authorizer) resolves a per-resource
dashboard_permissions grant. canEditDashboard now requires the
identity be Admin/Owner, the dashboard's creator, or hold a grant of at
least Editor; canManageGrants is deliberately stricter (creator or
Admin/Owner only, never grant-derived access) so a user who can edit a
dashboard only because of a grant can't extend or re-grant that access
to themselves or others. Wired handlers: PUT/DELETE
/dashboards/{id}/permissions/{userId}, GET .../permissions.
Two real bugs found and fixed while wiring this up, before any of it
touched a live database:
- handleCreate/handleImport never stamped created_by from the
authenticated identity, so every dashboard was owned by "anonymous"
regardless of who made it -- the ownership check would have been
meaningless. Also fixed: ImportDashboard trusted the exported JSON's
created_by verbatim, so re-importing someone else's export would
leave the actual importer unable to edit their own copy.
- metadata/migrations/0024_create_dashboard_permissions.sql's CHECK
constraint diverged from /docs/phase-4-rbac-design.md's schema
(allowed role='admin', nullable granted_by). Reconciled via
0033_restrict_dashboard_permissions_role.sql: Admin/Owner already
have tenant-wide access so a resource-level "admin" grant is
meaningless, and every real grant now always has an attributable
granter.
enterprise/internal/rbacstore gets the storage side: raw CRUD
(dashboard_permissions.go) plus DashboardPermissions
(dashboards_adapter.go), an adapter implementing
api/dashboards.PermissionStore -- same pattern as audit.QueryAPILogger
over queryapi.AuditLogger. Wired into enterprise/cmd/enterprise-api
only; plain api/cmd/api passes nil (ownership/Admin checks still work
via the nil-permissions fallback, just without the "granted" bonus).
Verified: the full own/granted/admin/creator matrix, including the
granted-editor-cannot-manage-grants regression, passes against a fake
PermissionStore (api/dashboards/handler_test.go, all existing tests
also still pass unmodified in behavior). Real integration tests exist
in enterprise/internal/rbacstore/rbacstore_test.go (skip-gated on
RBACSTORE_TEST_POSTGRES_ADDR, same convention as every other
Postgres-backed piece this phase) but have not run against a live
database in this environment -- disclosed in threat-model.md,
phase-4-runbook.md, and enterprise/README.md alongside every other
piece carrying the same gap. Also fixed a stale path in
phase-4-runbook.md's dashboards-tenant-scoping section
(./internal/dashboards/... -> ./dashboards/..., stale since that
package moved out of api/internal/ earlier in this phase).

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.
