Acknowledged telemetry publication window controller: sealed / publish · case 01

While sealed, event publish produces idle/release_window instead of awaiting/send_window.

ROOT CAUSE

In sealed, the publish handler runs release window and enters idle; it must instead run send window and enter awaiting.

VERIFIED REPAIR

In phase sealed, classify publish as transition to awaiting and emit send_window.

Unsuccessful approach: The partial repair chooses awaiting/send_latest_only, which still violates this phase-specific event contract.

Case contract

For the stipulated Acknowledged telemetry publication window controller, initialize the explicitly shown resource registers from seed (1..5), then consume classified events sequentially. After each event return a deep snapshot of phase, resource registers, and cumulative emitted control frames. The explicit ten phase/event rules and their resource effects define admission and response semantics. Unlisted events preserve phase and emit rejection. Payload is the consecutive integers seed through 2*seed+1. Empty event input returns no observations.

Why this case matters

Incorrect event admission now changes concrete queued data, resource ownership, or emitted protocol frames and subsequent trace behavior.

Verification & scope

Bounded offline control-plane abstraction with prescribed initial registers and classified events. Not a named protocol implementation or conformance test; excludes wire parsing, transport retries, physical execution, authentication, crash persistence, and timing. Related event faults share the full corrected controller and evaluation group. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
