Per-side --debug-info transports are not in the config tier

Index: Known gaps, closed

Status (2026-10-31): CLOSED (archive). debug.info is now the config home of --debug-info (ADR-091 D4, 2026-10-31 amendment). It is a list of entries in the flag's own [old=|new=|both=]PATH grammar, so the per-side home is the D3 side qualifier, not a pair of debug_info.old/debug_info.new keys. That keeps one grammar on the CLI and in config. A side's own entries replace the shared ones for that side, as on the command line. Relative paths resolve against the config file. The flag stays, wins, and is never merged with the list. dump has one operand, so it refuses an old=/new= entry by name. It backs a core flag, so --set and the typed config_overrides refuse it, naming --debug-info, like every other core key. Resolver: abicheck/workflows/config_run_inputs.py. Tests: tests/test_config_run_input_homes.py.
