Serial line command and data mode controller: command / line reset · case 01

While command, event line_reset produces data/enable_payload instead of command/reset_parser_report.

ROOT CAUSE

In command, the line reset handler runs enable payload and enters data; it must instead run reset parser report and enter command.

VERIFIED REPAIR

In phase command, classify line_reset as transition to command and emit reset_parser_report.

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

Case contract

For the stipulated Serial line command and data mode 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.
