📝 WalkthroughWalkthroughThe subdomains plugin renames SRV target configuration to subdomain target, adds CNAME support, centralizes record-type availability, updates Filament forms, and documents requirements for A/AAAA, CNAME, and SRV records. ChangesSubdomain record types
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This PR adds CNAME creation and renames the persisted target field, but CNAME remains available in cases where creation will reject it, and interrupted or repeated DNS updates can leave Cloudflare state orphaned or duplicated. The schema rename also requires coordinated deployment, while the new return annotation still needs correction; merge should wait for these issues to be fixed or explicitly accepted.

61-63: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winDo not require an allocation for CNAME records.
RecordType::availableRecordTypes()exposes CNAME when the node has a target, even when the server has no allocation. This guard throws before the CNAME branch runs, so that supported CNAME configuration cannot be created. Require an allocation only in the SRV and A/AAAA branches.🤖 Prompt for AI Agents

CNAME doesn't require an allocation, so that should be available.

Allocations with 0.0.0.0 or :: should ALWAYS be blocked. Doesn't matter which record type.

I do not understand why SRV and CNAME records should be blocked while having an invalid allocation. The values are never used in the created records, since they only use Subdomain target.
If the user has a working install where they use 0.0.0.0 on nodes, and can create Subdomain target to route to server correctly, I think we should allow them to create SRV and CNAME records.
I cannot see a scenario where a user could connect via Subdomain target, but couldn't connect via a subdomain, where allocation IP was the cause.
I think we should keep restrictions here as open as functionally possible and let the user deal with ensuring everything outside wings routes correctly.

Because I have a personal vendetta against 0.0.0.0/:: and I will deny their existence.

Ah yes, of course.
I am still not a fan of this logic. Since having 0.0.0.0 and :: is explicitly allowed in allocation settings, it feels wrong to disable functionality here, even when it should be unaffected.
I would expect the wings documentation to mention that using 0.0.0.0 and :: for allocations are discouraged, and that the wings system_ips config option exists for docker, as well as needing to clear panel cache for it to apply, before I would be fine with changing this, since I had to spend some time searching through the discord and reading the code to fix that on my setup.

@Boy132 Additionally, if you insist on blocking all subdomain types for 0.0.0.0, including CNAME, then this PR will NOT close #79.
@Svenum described having a server with a dynamic IP, which pretty much requires using 0.0.0.0 allocation binds. While I have static IPs on servers and will be unaffected by this, I do not see a clean workaround for their setup.

I cannot think of a use case where CNAME and SRV records would need different targets for servers on the same node, so I think using the same target for both is fine.
Closes #79
