Scoped policies resolved through the single capability matrix, grants with
server-set expiry, approval queue with once/session/always/deny, pre-side-effect
gate that releases a once approval exactly once against the argument hash,
run budgets with exhaustion events, honest cancellation receipts; projects,
conversations, branch lineage and search over the indexed fields.

Immutable content-addressed artifact versions with If-Match, lineage that must
resolve under the caller, unified diffs, promotion; sources/passages/citations
with server-side hashing and dedupe, citation integrity checks and revisioned
research notebooks. Cross-tenant access is 404 and audited.

Stdlib per-tenant service: trusted-header identity (router/relay/worker,
constant-time keys, slot pinned to the pod), fail-closed card flags with
capability negotiation, tenant-scoped store (atomic writes, revisions,
append-only ledgers, content-addressed blobs, manifest), audit outcome for
every request, and the /hux/v1 pipeline that maps errors to hux.error.v1.
