Tobias GesellchenandClaude Opus 4.7 f951fc92df feat(handlers): proxy-aware RemoteAddr via opt-in TrustForwardedHeaders
Wire up X-Real-IP / X-Forwarded-For / True-Client-IP support for
deployments fronted by a reverse proxy, while staying safe on flat-LAN
deployments where a malicious speaker could spoof those headers
directly.

Two new fields on `datastore.Settings`:

* TrustForwardedHeaders (bool, default false) — opt-in switch.
* TrustedProxyCIDRs ([]string, default `["127.0.0.0/8", "::1/128"]`)
  — only requests whose immediate TCP peer falls in one of these
  blocks may have their source IP rewritten from forwarded headers.
  Loopback default matches the documented same-host nginx layout in
  docs/guides/HTTPS-SETUP.md.

New middleware in `pkg/service/handlers/middleware_realip.go`:

* TrustedRealIP wraps `chi/middleware.RealIP` with a trusted-peer
  gate. When the immediate TCP peer is in the allowlist, chi's
  parsing handles the actual header → IP rewrite. When it isn't
  (e.g. a speaker sending forwarded headers itself), we ignore the
  headers and r.RemoteAddr stays as-is.
* ParseTrustedProxyCIDRs converts string CIDRs into *net.IPNet,
  applying the loopback default on empty input and erroring loudly
  on invalid entries.

Server.TrustedRealIPMiddleware() returns the middleware (or nil) by
reading the live settings; the router setup in
cmd/soundtouch-service/main.go installs it as the very first
middleware so SnapshotMiddleware and downstream handlers see the
correct r.RemoteAddr.

HandleMargePowerOn now prefers r.RemoteAddr over the body's
self-reported `<IPAddress>` for outbound credential push:

* The body field is treated as a hint only — a malicious LAN speaker
  could set it to any value; using it for outbound HTTP requests is
  the SSRF surface the previous zeroconf hardening was guarding
  against from the sink side. Fixing it at the source as well closes
  the gap entirely.
* When body IP and TCP source disagree, a log line names both and
  the device ID so the discrepancy is investigable.
* RemoteAddr is unparseable → fall back to the body so we don't
  silently drop the priming.

docs/guides/HTTPS-SETUP.md gains a follow-up note next to the existing
nginx snippet explaining the new flag, the loopback-only default, and
the explicit warning against enabling the flag on a flat-LAN
deployment without a real proxy.

Eleven test cases in middleware_realip_test.go lock in the gate
behaviour: trusted peers honoured for X-Real-IP / X-Forwarded-For /
no-headers / IPv6, untrusted peers' headers ignored, garbage values
rejected, ParseTrustedProxyCIDRs covers default / override / invalid.

Tobias GesellchenandClaude Sonnet 4.6 6b90d2c994 docs: rewrite README and survival guide for post-shutdown user journey
Rewrite README.md to be concise and tool-focused (no code snippets),
clearly presenting all five tools and their use cases. Expand the
soundtouch-service section to cover both user scenarios and redirect
method trade-offs.

Rewrite SURVIVAL-GUIDE.md around the same two scenarios with step-by-step
instructions. Remove deprecated hosts-file method from all user-facing
docs; update MIGRATION-SAFETY.md, HTTPS-SETUP.md, and SOUNDTOUCH-SERVICE.md
to reflect only the two supported methods (XML redirect and DNS/DHCP).

Tobias Gesellchen 5edab77209 feat: add comprehensive TLS certificate SAN support with wildcard domains
- Add RFC-compliant wildcard certificates (*.api.bose.io, *.api.bosecm.com) for automatic API coverage
- Include additional Bose production domains (worldwide.bose.com, music.api.bose.com, bose-prod.apigee.net)
- Implement TLS certificate request logging and wildcard domain matching logic
- Add detailed TLS handshake debugging with connection state tracking
- Wrap TLS listener with logging to capture certificate selection and handshake failures
- Update documentation with wildcard certificate coverage and debugging features
- Normalize test data to use consistent local IP addresses

This enables automatic coverage of all current and future Bose API subdomains
while providing comprehensive TLS debugging for DNS redirection troubleshooting.
