A new skill, tool or external destination is a surface with no flag path on it. The two autonomy categories matter for a different reason: when runs stop being initiated by people, and when people are further from each run, the in-flow half of the mechanism loses the human it assumed, and a feedback loop that captured nothing is indistinguishable from one that had nothing to capture. Model and prompt changes are excluded — they change what gets flagged, not whether anything can be. ⚠️ tool_added was removed from this list after assembly: the feedback instrumentation is unchanged. A new tool gives users something else to give feedback about; it does not remove the channel by which they do. It was listed by 36 of 41 controls, which meant one new tool invalidated almost every evidence item in a ledger — and a delta that invalidates everything says nothing." }, { "control_id": "ARS-37", "citation_id": "ARS-1.0-37", "applicable": true, "applicability_because": [ { "path": "identity/lifecycle_state", "value": "production" }, { "path": "tools/2", "value": "update-ticket = write" }, { "path": "tools/3", "value": "draft-reply = write" }, { "path": "tools/4", "value": "issue-refund = spend" }, { "path": "tools/5", "value": "send-email = send" }, { "path": "data_sinks/2", "value": "inbound-ticket-content is external (inbound)" }, { "path": "data_sinks/3", "value": "customer-mailbox is external (outbound)" }, { "path": "autonomy/maximum_plausible_blast_radius/scope", "value": "single_customer" }, { "path": "data_sinks/0/data_classifications", "value": "support-database carries personal_data" }, { "path": "data_sinks/1/data_classifications", "value": "billing-service carries financial, personal_data" }, { "path": "data_sinks/2/data_classifications", "value": "inbound-ticket-content carries personal_data" }, { "path": "data_sinks/3/data_classifications", "value": "customer-mailbox carries personal_data" }, { "path": "skills/0/data_classes", "value": "customer-lookup handles personal_data, confidential" }, { "path": "skills/1/data_classes", "value": "ticket-triage handles personal_data" }, { "path": "skills/2/data_classes", "value": "reply-drafting handles personal_data" }, { "path": "skills/3/data_classes", "value": "goodwill-refund handles financial, personal_data" }, { "path": "skills/4/data_classes", "value": "customer-correspondence handles personal_data" } ], "via_changes": [ "destructive_action_added:send-customer-email", "destructive_action_added:send-email", "external_destination_added:mail-relay.internal.acme.example/transactional", "external_destination_added:notifications.vendor.example/dispatch", "outbound_transmission_added:send-email" ], "evidence_invalidated": [ "ev-approval-gate-enforced", "ev-approval-volume-measured", "ev-correlation-ids", "ev-cross-tool-flow-policy", "ev-destructive-inventory-complete", "ev-eval-covers-destructive", "ev-exfiltration-channels-enumerated", "ev-feedback-loop-instrumented", "ev-idempotency-keys", "ev-incident-taxonomy", "ev-injection-suite-run", "ev-retention-covers-artifacts", "ev-review-board-package" ], "accepted_evidence_kinds": [ "manually_verified", "attested" ], "attestation_alone_sufficient": true, "invalidation_note": "A severity taxonomy is a mapping from what can go wrong to how badly, so it expires when either side moves.
