Detailed Description

RTT drain-model state (discovery, line assembly, observability).

cb_addr is 0 until the scan finds a validated control block; next_scan / scan_gap implement the backoff cadence; line / line_len assemble the in-flight text line; the counters feed the end-of-run report.

Invariant: line_len < k_rtt_line_max at all times.; cb_addr is either 0 or points at a validated ID match.
