Delimited batch command controller: sealed / validation failed · case 01

While sealed, event validation_failed produces committed/apply instead of idle/reject_discard.

ROOT CAUSE

In sealed, the validation failed handler runs apply and enters committed; it must instead run reject discard and enter idle.

VERIFIED REPAIR

In phase sealed, classify validation_failed as transition to idle and emit reject_discard.

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

Case contract

For the stipulated Delimited batch command 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.
