Follow-up to the FAQ + Tag refactor in this same PR. Three additional
handler areas now run through the route-level g.KBAccess* guard:
- chunk.go : full refactor — helper effectiveCtxForKnowledge and
validateAndGetChunk's access check are gone; the
handler's chunk-fetch + ownership-mismatch check stay
as defence-in-depth (a same-tenant attacker can't
pass mismatched knowledge_id + chunk_id).
- knowledge.go and knowledgebase.go : routes now run the guard
BEFORE the handler. The in-handler
validateKnowledgeBaseAccess /
resolveKnowledgeAndValidateKBAccess helpers stay for
now because they branch on the agent_id query param
(specific-agent check vs. any-agent fallback) — that
handler-specific branch can collapse into the guard
in a follow-up. The duplicated DB roundtrip is
negligible compared to the handler's main work.
New middleware exports:
- KBIDFromChunkIDParam : walks chunk_id → KnowledgeBaseID via the
chunk's denormalised column.
- g.KBAccessReadFromChunkIDParam / g.KBAccessWriteFromChunkIDParam
: convenience methods on rbacGuards.
Route changes are purely additive (existing role / ownership guards
stay in place; the new KB-access guard runs after them and rewrites
the request's tenant context to the source tenant for shared KBs).
No new dependencies on the kbShareService / agentShareService at the
handler level for chunk.go — those move to the route layer.
Tests pass; behaviour unchanged.
Before this change, the `organization_members` table keyed on user_id —
joining an org as a Viewer in tenant T meant only that one user got
visibility on shared KBs/agents, while the rest of T (including its
Owner) saw nothing. The mismatch surfaced as confusing UX bugs:
"my colleague shared this with us, why can't I see it?"
This change replaces `organization_members` with
`organization_tenant_members`. Membership and Org-RBAC role now key on
(org_id, tenant_id); `representative_user_id` stays as a display-only
label of the user who first brought the tenant in.
Permission resolution gains a 3-D cap so tenant-RBAC stays honest under
cross-tenant sharing:
effective = min(share.Permission, tenant_org_role, tenant_role_cap)
where tenant_role_cap pins tenant Viewers to OrgRoleViewer regardless
of the org-level grant. A Viewer in their own tenant cannot edit a
shared KB even if the org granted Editor — preserves the
"Viewer = read-only everywhere" promise.
Migration 000045 backfills `organization_tenant_members` from the old
table by collapsing each (org, tenant) group to its max role, then
renames the old table to `organization_members_pre_plan3` for safe
rollback. Sqlite mirror (Lite mode) is fresh-bootstrap: the init
schema replaces the old table directly.
Routes: member-management URLs change from `:user_id` to `:tenant_id`.
Org create / join / leave now require Admin+ in the caller's tenant —
joining an Org affects everyone in T, so the decision can't sit with
a Viewer.
Frontend: OrganizationSettingsModal + store update to address members
by tenant_id.
