Stale dynamic-combo keys no longer affect graph traversal.

Full context for agent readers

A dotted key under a dynamic-combo input is declared only when it resolves under the active selector. This prevents a key retained from a previous selection from creating false reachability or a false dependency cycle while preserving traversal through the same key when its selection is active.

This follows the unresolved review finding at #905 (comment) after #905 merged.

Two asymmetric regressions use the same dotted key: the stale-selection graph remains acyclic, while selecting the owning branch reports the real cycle.

Local tests and formatters were not run because the owner has temporarily prohibited resource-heavy local commands on this host. Remote CI is the verification path for this branch.

📝 Walkthrough

Walkthrough

The change makes input declaration checks selection-aware for dynamic-combo dotted keys. Validation and graph traversal now ignore stale or unsupported keys. Tests cover cycle detection for selected and stale dynamic-combo inputs.

Changes

Dynamic input declarations

Layer / File(s) Summary
Selection-aware declaration and traversal
comfy_cli/cql/engine.py
Validation passes submitted node inputs to _node_declares_input. Dynamic-combo dotted keys are accepted only when they resolve under the current selection. Autogrow prefixes remain accepted, while stale and ordinary unsupported dotted keys are ignored during link-target discovery.
Dynamic-combo cycle validation
tests/comfy_cli/cql/test_validate_server_parity.py
Added a dynamic graph fixture and tests for cycle behavior with selected and stale dotted sub-keys.

Priority: ⬇️ Low

Merge Risk: 🟠 High · up to 046a6

Valid workflows using plain COMBO dynamic options may bypass cycle detection. Correct the port classification and add regression coverage before merging.
