- Add `optional` kwarg to DynamicSlot.Input (default True). When False,
declaring a when=None Option is rejected because the unconnected branch
is unreachable.
- Always publish `forceInput=True` on the slot itself. slotType may
include widget-capable types (INT/STRING/etc.) but a DynamicSlot is
meant to look like a connection point, never a widget.

Grouping AnyType with concrete types conflates the known-type case with
the unresolvable-wildcard case under one branch and muddies slotType.
AnyType must stand alone as when=io.AnyType so the two states stay
distinct in both dispatch and the serialized schema.

Bug fixes:
- execution.py validate_inputs() now calls _select_option for DynamicSlot
links instead of validating against slotType. Old code accepted any
concrete upstream type whenever AnyType was enumerated (slotType
contained '*', which validate_node_input treats as accept-anything).
Verified end-to-end: LATENT into an IMAGE+AnyType slot is now rejected.
- Thread live_input_types through get_input_data so custom V3
validate_inputs() sees the same DynamicSlot branch that finalization
picked, instead of re-finalizing without resolver context.
- DynamicSlot.Option._when_types is now an ordered tuple (preserves
author declaration order); _slot_io_type/slotType ordering was
previously nondeterministic via frozenset iteration.
Design:
- DynamicSlot.Input.get_all() now returns [self] + children, matching
Autogrow / DynamicCombo so consumers like PriceBadge work uniformly.
- Enforce per-option type uniqueness in DynamicSlot.Input: each io_type
may appear in at most one option's 'when', and at most one option may
declare when=None. Removes the ambiguous first-match-on-overlap case
for single concrete types; ordering still matters when upstream is a
multi-type union.
- Reject non-Option entries in options=[...] explicitly.
Polish:
- Trim verbose DynamicSlot docstrings and inline comments.

Replaces the old connected/unconnected fixed-child DynamicSlot with a
type-keyed option list. Each Option declares a 'when' condition (None,
io.AnyType, a single ComfyType, a list, or a MultiType.Input) and the
child inputs revealed when that condition matches the slot's resolved
upstream type.
Selection happens at schema-finalization time using live_input_types
computed by TypeResolver, so API-only workflows (no frontend) get the
same expansion the UI would.
- _io.py: redesign DynamicSlot.Input / Option; auto-derive slotType as
the union of all non-None when sets; expose it via as_dict so the
frontend knows what types are accepted; the class io_type stays
COMFY_DYNAMICSLOT_V3 as the parse-time dispatch tag.
- type_resolver.py: return the auto-derived _slot_io_type for
DynamicSlot.Input; document the AnyType (*) limitation.
- execution.py: validate links into a DynamicSlot against slotType,
not the dispatch tag COMFY_DYNAMICSLOT_V3.
- tests: new test_dynamic_slot.py + regression coverage in
test_type_resolver.py.

register_dynamic_input_func is a private helper (underscore module, not
in __all__, not re-exported). Its only callers are the three core
setup_dynamic_input_funcs() registrations, all of which were updated
together. No third party can be relying on the old 5-arg signature, so
the inspect.signature shim and accompanying backward-compat tests are
over-engineered.

* Add _parse_link helper validating both node_id (str) and slot_idx (int,
rejecting bool) so malformed API JSON (e.g. ['n1', '0']) degrades to
AnyType instead of crashing with TypeError.
* Add slot_idx type guards in resolve_output_type and is_output_list.
* Extract _get_class_def_for_node helper to dedupe node/class lookup
across resolve_output_type, is_output_list, get_declared_slot_io_type.
* register_dynamic_input_func now detects 5-argument legacy callables
via inspect.signature and silently wraps them; preserves backward
compatibility for any custom node that registered its own dynamic
input expansion against the pre-live_input_types signature.
* Tests: malformed link (str slot idx, wrong arity), bad slot type
directly to resolve_output_type, non-string class_type. Tests for
the legacy 5-arg shim and the modern 6-arg passthrough, including
callables with uninspectable signatures.
