RCLK-WP-0003	workplan	Implement isolated authority and application clock	infotech	railiance-clock	proposed	codex	custodian	2026-09-14	2026-09-14	RCLK-WP-0002	904e08b5-978f-5bfc-b543-ca5347a56ac5

Implement only the reviewed contract. Runtime language selection, API schema and dependency policy follow RCLK-WP-0002; no live secrets needed for fake-clock development.

Implement authority sample and health adapter

status: wait
priority: high
state_hub_task_id: "0d7841ac-b652-54d5-8cb0-da430bf9ff9d"

Depends on 0002 adopted sample/trust/UTC contract. Implement bounded sample exchange, nonce binding, health/error state and epoch handling with disposable signing keys. Verify C02–C05/C13–C15.

Implement application clock and attribution interface

status: wait
priority: high
state_hub_task_id: "b14d9306-eef8-5d78-8b3d-0c514cf10666"

Depends on adopted interval/platform contract. Provide explicit quality states, monotonic mapping, sample-age policy, restart/suspend invalidation and immutable event attribution. Verify C01/C06–C09/C11/C12.

Prove isolated consumer integration and package review

Run deterministic boundary/property tests plus adversarial delay/replay and real platform lifecycle probes. Demonstrate +/− local clock skew with no OS changes. Preserve consumer approval/CAS failures with fixtures; publish dependency/SBOM and reproducible build evidence. No native production claim from synthetic fixtures.
