F1 policy writes and allow grants are human-surface only; F2 worker trust is
confined to the hook allowlist and unexpected exceptions become audited 500
error records; F4 external side effects release only for the same run and
argument hash; F6 the gate honours budget exhaustion; F8 only the gateway
can vouch for an empty process registry and failed receipts can be
superseded; F11/F12 receipt revision and unshipped card routes.

Stdlib client the agent runtime calls around its tool loop; fails closed for
side effects, fails open for telemetry, never carries raw arguments or outputs.

Per-conversation monotonic event ledger with idempotent emit, SSE replay from
Last-Event-ID, per-kind detail allowlists and secret scrubbing, surface-aware
serve-time redaction; memory as an append-only ledger with no-store,
supersede, forget and retrieval tombstones so 'do not remember' blocks both
persistence and retrieval; sensitive-topic scoping, notices, conversation
forget and a retention job that never touches audit.

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.

Schemas, examples and a flag registry for the twelve HUX cards, a dependency-free
validator, the governance rules (memory ledger, autonomy matrix, friendly modes
mapped to real Switchyard routes, privacy defaults, suggestion gating, release
state machine) and the contract doc UI work codes against.
