The diagnostic export captured the symptom of #345 (a TuneIn select
escaping to the dead Bose Apigee gateway → BMX_HTTP_ERROR 4501 →
INVALID_SOURCE) but none of the data that decides where a speaker sends
its marge/BMX/streaming traffic, so we couldn't tell whether the request
was ever redirected to AfterTouch.
Collect that per speaker:
- New collectSpeakerRedirectConfig prefers the on-device
SoundTouchSdkPrivateCfg.xml over SSH (archives raw + parses
marge/stats/swUpdate/bmxRegistry URLs), and falls back to
`getpdo CurrentSystemConfiguration` over telnet when SSH is
unavailable — the same channel the telnet migration uses. Parsed URLs
and provenance land in diagnostic.json as redirect_config: source
(ssh|telnet|none), ssh_reachable, and inferred_migration_method
(telnet when only telnet answered, since xml/hosts/resolv all need SSH).
- Pull redirection-relevant files over SSH: /etc/hosts(.original),
/etc/resolv.conf, the resolv-method hook, /mnt/nv/remote_services, and
the pre-migration .original backups (CA bundle and the URL config).
- Dump the speaker firewall (iptables-save; ip6tables-save is empty on
FW 27.0.6 but harmless) to catch self-inflicted DROP rules (cf. #354).
Export ParseGetpdoConfig from pkg/service/setup and add a test pinning
the field-name contract the export depends on.
Diagnostic-collection only; does not change migration or playback.
