Bounded initial Q2 reference implementation for platform assurance. Producer meaning stays in S3; deployable monitoring packaging stays with a selected package owner. No public listener, credential custody or incident workflow.

Define metadata-only receiving and retention contract

id: RTEL-WP-0002-T01
status: done
priority: high
state_hub_task_id: "ac73553d-5bd4-5dff-8307-95a29bffe474"

Implemented docs/signal-contract.md and a pinned platform stream contract. Exact identities/signals, finite states, payload limit, freshness, replay, proposed retention and local recipient semantics are explicit. Live acceptance of the proposed budgets and recipient remains T04, not implied by this schema.

Implement durable receipt and operator inbox reference

id: RTEL-WP-0002-T02
status: done
priority: high
state_hub_task_id: "dacc9e2d-9321-5d39-afc4-88326f5c6930"

SQLite acceptance and notices commit together; strict rejection, duplicate idempotence, explicit acknowledgments and bounded retention are tested. This is a local private CLI implementation; acceptance says local-inbox-only.

Prove platform adaptation and absent-emission semantics locally

id: RTEL-WP-0002-T03
status: done
priority: high
state_hub_task_id: "a8ed3588-4240-5278-b03f-04c3237a52f9"

Adapter preserves producer evaluation time and classifications. Tests prove failure survives receiver restart, inbox addressing/acknowledgment, never-seen and stopped-producer detection, replay refusal, wrong-scope rejection and retention of unacknowledged evidence. Local simulated-time tests establish implementation behavior, not actual scheduled notification delivery.

Accept private runtime and controlled end-to-end delivery

id: RTEL-WP-0002-T04
status: wait
priority: high
state_hub_task_id: "ceb14fdc-b3fd-5a22-870d-d835a9d52055"

Choose package/runtime execution owner with cluster/activity-core; confirm the operator recipient, producer/watchdog cadence, retention/storage/backup and private authenticated access. Install only through accepted authority. Prove a controlled failure and stopped producer reach and are acknowledged by the named operator, and receiver/scheduler failure is independently detectable. Preserve receipts across restart; demonstrate capacity/retention handling. Only these receipts can satisfy RPF-WP-0036-T04. No package repo name or deployment grant is invented here. This live task holds the residual explicitly.
