Canonical cadence observer admission

NK-WP-0035; KG-WP-0005. The observer now consumes source-authored extensions.netkingdom.evidence_class, matching NetKingdom's profile namespace. The historical extensions.net-kingdom is refused with an explicit migration diagnostic, including conflicting dual-namespace inputs. Missing/malformed owner classification is an error; no classifier is inferred from traffic or event names. The two local copied fixtures use the canonical namespace. They are local algorithm inputs, not deployment, source approval, or profile-wide adoption.

The profile remains proposed. Imported contract is InfoTechCanon candidate document 0.2.0 / wire schema 0.1, bundle b08b4d95fc4b0bd3, schema SHA256 6d52692eb1e4d1325e0d6062d95acded98beddaae5bcfe24c6f0e91f1b6be6ae. Schema validation belongs to the owner artifact; no competing generic schema is bundled here. The source class inventory stays source-owned.

Reuse the evidence engine's delivered interfaces

AUDIT-WP-0009-T04/T05/T06/T07 are done. Reuse, without duplicating:

• POST /v1/events authenticated envelope; receiver heartbeat type audit-core.heartbeat with asserted covered class at data.class.
• Protected AUDIT_CORE_SENDERS registry object carries source-owned canonical emission_cadence, plus exact source/tenant/evidence/credential bindings. heartbeat_classes maps covered event class to maximum gap seconds. The non-secret scope overlay may add/shorten heartbeat bounds but cannot insert/change emission_cadence; platform must provision the protected registry.
• GET /v1/reconciliation?source=<exact>&tenant=<exact>&since=<bound>&until=<bound> gives accepted counts, not payloads. Own-source sender read is allowed with may_read=false; cross-source requests return403. Explicit equal source/tenant and window boundaries are required for a meaningful local comparison.
• GET /v1/stream-findings evaluates missing registered heartbeats and declared rates. It requires a may_read identity with full tenant scope. It is not a tenant-filtered observer feed; request an owner-delivered sanitized observation or separately governed read lane rather than widening a source writer token.

Approval Engine already publishes receiver-compatible heartbeats and has exact sender/source approval-engine, tenant tenant:platform. Its local transition classes use bare issuance/use/supersession/revocation while accepted event types are approval.issuance/use/supersession/revocation; owner mapping must preserve both count coordinates. Current prepared source settings derive from the shared coordination frame: heartbeat f=3600s, registration 2f=7200s and effective deadline 3f=10800s after the receiver's 1.5 grace. The copied source fixture retains the same frame digest; neither source configuration nor a fixture is live admission. Canonical declaration admission and heartbeat mapping need actual owner receipts; existing ingestion evidence alone does not prove cadence monitoring was enabled.

Qonto's source is structured stdout, process-instance scoped with event class audit.heartbeat and its own source transition/snapshot counters. Its deployment owner must deliver a bounded capture and snapshot; no audit-core sender/feed is declared in the reviewed receiver source. If routed through Audit Core, owners must explicitly translate the heartbeat envelope, bind exact sender+tenant, retain source instance/sequence/window semantics, and admit its declaration. AUDIT-WP-0013-T04 now supports explicit stream_instance_id on receiver reconciliation. A reviewed receiver release is still required, and acceptance time must be aligned with source/sequence windows. An unbounded database accepted count cannot replace a process-local snapshot.

local-identity has no registered sender or evidence feed, declares no heartbeat, and remains the owner's explicit activity-scoped incompatibility. Do not accept reconciliation-only as satisfying NetKingdom's rare-class conjunction or create an observation from a local TSV file merely to close adoption.

Owned operational wait and acceptance

KG-WP-0005-T03 remains wait/blocked on a runtime-owner supplied authorized Qonto capture from startup through a request allow/deny, periodic heartbeat at the declared interval, and same-instance reconciliation. The namespace migration does not produce that feed. main --live still drives the adjacent source's AuditLogger with a fixture client; it is local emit-path evidence.

Existing executable seams are live._confirm_stream (instance/sequence/count admission), cadence.emission_cadence_from_dict (owner-classified projection), stream.evaluate_stream (heartbeats/reconciliation/observations), and posture.evaluate_with_stream. Feed integration must retain source_id/tenant, declared heartbeat vs covered-class mapping, time bounds, process instance, contiguous sequence and durable/local count scope; missing or malformed inputs remain UNKNOWN or are rejected. A runtime owner returns bounded non-secret positive/missing-heartbeat/count-divergence plus failed-read receipts. Matching counts prove neither completeness nor event occurrence; findings detect omission after the fact. There is no automatic containment authority in this delivery.

Heartbeat coverage correction — 2026-10-15

StreamHeartbeat.covered_event_classes explicitly names the classes vouched for by a source or reviewed adapter. Matching requires both the transport event class and that coverage. Shared audit-core.heartbeat transport names alone cannot let a fresh issuance beat hide an expired revocation beat. Missing coverage does not satisfy a covered-class obligation; malformed coverage is refused. Count keys and observed traffic never infer this binding.

The Qonto source adapter explicitly maps its shared heartbeat to the three classes in its source-owned declaration. This is local source-path evidence, not admission of a collector or a receiver feed. The same envelope with an explicit receiver data.class must map only to that named class; do not set all declared classes on every Approval Engine heartbeat.

The existing 2026-09-15 sender bearer-revocation receipt in audit-core already proves scoped overlap/drop: replacement bearer 202 then 401, incumbent 202, for approval-engine and informed-decision. Reuse that exact historical proof; it does not prove lifecycle reconciliation or cadence registry admission. Receiver applies 1.5 grace to registered heartbeat intervals: the requested 172800 seconds would produce a 259200-second effective deadline. Record the source/receiver owner decision before admitting that bound; do not silently claim a 48-hour alert from that registration.

Shared frame decision — 2026-10-15

Founder resolved the earlier daily 48h/72h question by introducing one coordination frame, initially f=1h. Canonical configuration is coordination-engine/config/coordination-frame.json; NetKingdom's compiler regenerates the source-derived Qonto fixture alongside source/receiver artifacts and records the config digest. The historical Taxonomy draft fixture remains a historical worked example. Live admission must supply the actual configured frame/interval and preserve per-class scope; the source fixture cannot prove that a deployed process emits hourly heartbeats.
