A defaulted Encoder method that TrackedEncoder doesn't forward silently
no-ops through the wrapper — the host loop only ever holds the wrapped
box, so the feature dies for every session with nothing in the logs. The
trap has bitten three times (set_wire_chunking's §4.4 chunking probe,
set_pipelined's LN3 escalation, applied_bitrate_bps's ABR truth), and
every Phase 7 consolidation that adds a trait method re-arms it.
Source-text parse of the trait and the forwarding impl (both top-level
rustfmt items: block ends at the first column-0 brace, method names sit
on 'fn '-prefixed lines), then set equality — the reverse direction is
already a compile error, so equality == completeness. Mutation-verified:
removing set_wire_chunking's forward fails naming exactly that method.
16/16 today.
Limit stated in the test doc: name-set equality only — a forward whose
body delegates to the WRONG inner method still passes.
