Hostname Validation (#49): RFC 1123 hostname validation before DNS operations
- Validates label length (max 63 chars) and total hostname length (max 253 chars)
- Checks for valid characters (alphanumeric and hyphens)
- Rejects empty labels, leading/trailing hyphens, special characters
- Supports wildcards (*.example.com) in first label only
- Invalid hostnames are logged with warnings and skipped (won't fail reconciliation)
- New HostnamesInvalid counter in reconciliation results
Adopt Existing Setting (#58): Control whether dnsweaver adopts existing DNS records
- New DNSWEAVER_ADOPT_EXISTING environment variable (default: false)
- When false, existing records without ownership TXT are left unmanaged
- When true, dnsweaver creates ownership TXT to adopt matching records
- Prevents surprising behavior where dnsweaver silently takes over manually-created records
- Thanks to u/pheitman on Reddit for testing and feedback on this feature
Duplicate Hostname Detection (#54): Warn when same hostname appears in multiple workloads
- Logs warning with both workload names when duplicate hostname detected
- First workload wins (deterministic, alphabetical by service discovery order)
- New HostnamesDuplicate counter in reconciliation results

Domain Pattern Overlap (#52): Documented multi-provider matching behavior
- Clarified that hostnames are sent to ALL matching providers (split-horizon DNS design)
- Added examples for non-overlapping patterns using EXCLUDE_DOMAINS
- Documented that instance order doesn't affect provider selection
TTL Handling (#46): Documented TTL configuration and provider-specific behavior
- Added TTL handling section explaining caching behavior
- Documented Cloudflare quirks: proxied records use "Automatic" TTL (ignores configured value)
- Clarified that TTL changes require record deletion/recreation
