Model guidance

• Models are core-neutral Python data and transformations. Do not import Qt, application globals, controllers, repositories, services, or concrete backend plugins.
• Preserve meaningful user configuration and unknown metadata fields across load/save/copy. Promote legacy fields through explicit, backward-compatible migrations without ambiguous duplicates.
• ServerProfile separates connection data from metadata. Stable profile IDs, subscription ownership/key fields, display metadata, and connection fingerprints each have distinct semantics; do not substitute row position or display text for identity.
• Fingerprints must be deterministic for supported JSON-compatible connection documents. If compatibility requires a fallback, make its stability/diagnostics explicit rather than silently changing identity across runs.
• Encoders are the canonical JSON/ujson boundary. Preserve supported mappings/dict subclasses and surface useful failure context at the caller boundary.
• toURI() dispatch belongs to plugin protocol capabilities; model methods may remain compatibility shims but must not grow new protocol-specific branches.

Verification

• Test legacy/current mappings, unknown-field round trips, copies, deterministic identity, subscription migration, malformed serialization, and plugin-based export.
