fix(cql): grow nested auto-grow slots under dynamic combos; stop counting link-only subs as widgets

[skishore23]

Stacked on #809 (kishore/upload-companion-widget) — both change the same engine.py widget-order functions. Retarget to main once #809 lands.

Why

The in-app agent cannot wire a Load Image / Load Video / Load Audio into any node whose reference inputs are COMFY_AUTOGROW_V3 groups nested under a COMFY_DYNAMICCOMBO_V3 option — Nano Banana 2, Seedance 2.5 r2v, MiniMax H3 r2v, and 24 other partner nodes. Reproduced on the pin the agent ships (50fd0a43) with the cloud object_info.json:

• agent-built GeminiNanoBanana2V2: add_node writes inputs: []; connect A.IMAGE B.model.images.image_1 and …B.model.images both fail input not found;
• UI-built api_minimax_h3_r2v: only the one free slot the frontend pre-created (image_2) wires; image_3, reference_videos.video_2 fail;
• agent-built dynamic-combo nodes carried phantom widget slots for the groups (model.images, model.files), shifting every later widget: converting Nano Banana 2 gave response_modalities: null, system_prompt: 42, temperature: "fixed", top_p: "IMAGE". The published widget catalog named those phantom slots too, so through the CRDT doc host a UI-built MiniMax H3 node's seed position mapped onto model.reference_images ("filename in the seed widget").

Root cause

A. workflow_ops._resolve_input_target only recognised a group when the node's inputs already held a COMFY_AUTOGROW*-typed base entry — true only for top-level groups on CLI-built nodes. Nested groups never get one; UI-built nodes never carry one (the frontend writes the grown images.imageN slots, never the base). So even a UI-built top-level BatchImagesNode couldn't be base-addressed or grown past its free slot.

B. widget_order_default / widget_defaults expanded a dynamic combo's sub-inputs with their own helper (_dynamic_sub_widget_defaults) that included link-only sub-inputs, while widget_order_for_node (_expand_widget_entries) skipped them. add-node, the catalog and set-widget disagreed with each other.

Change

• engine.py: one walk. _expand_widget_entries(m, values, first_key=…, sub_links=…) drives widget_order_default, widget_defaults (new _widget_default) and widget_order_for_node; the duplicate sub-widget helpers are removed. New Graph.autogrow_groups(class, widgets_values) lists every group the node's current selection exposes, dotted as the frontend names them (model.reference_images). New Port.autogrow_element_type (the template's declared input type) and Port.autogrow_limits ((min, max) with max = len(names) else template.max, as applyAutogrow derives them). autogrow_slot_example uses the schema names. morphism_to_dict (nodes show) adds dynamic_options: [{key, inputs:[…]}] per option and, on any autogrow input, element_type, slots {names|prefix, min, max}, wire_as.
• workflow_ops.py: _resolve_schema_autogrow mirrors dynamicWidgets.ts — base address reuses the lowest free existing slot, else appends the next schema-named slot; a dotted key or bare element name must be that exact next slot (gap → rejected with the next free key); source type must match the group's element type (type mismatch); never grows past max. _autogrow_group_port resolves top-level and nested groups from the node's own widgets_values. Grow/apply splits a slot's group on the last dot (_autogrow_base) so model.images.image_1 → model.images, not model.
• Fixture tests/comfy_cli/fixtures/object_info_nested_autogrow.json: the production catalog's entries for LoadImage/LoadVideo/LoadAudio/SaveImage/BatchImagesNode/GeminiNanoBanana2V2/MinimaxHailuo03ReferenceNode/GrokImageEditNodeV2, tooltips stripped, declaration order preserved.

Red → green

26 new tests, all written and watched fail first (11 == 8, AttributeError: autogrow_groups, input 'model.images.image_1' not found … inputs: []):

• tests/comfy_cli/cql/test_nested_autogrow.py (10): default order = the captured frontend shape (MiniMax 8 values, seed at 5); add-node layout round-trips through set-widget indexing; autogrow_groups follows the node selection; template/limits from the schema; nodes show payload names group, element type, slots.
• tests/comfy_cli/command/test_workflow_edit_nested_autogrow.py (16): grow by name / by base / explicit next key; gap rejected with the next free key; bare element name; selection-dependent groups; UI-built free-slot reuse then growth; Load Video + Load Audio into their groups; type mismatch refused; max enforced; UI-built top-level BatchImagesNode; set-widget lands in the frontend position; agent-built node converts with model.images.image_1/2 links and unshifted seed/temperature/top_p and validates; nested grow op replay idempotent; CLI add-node + connect envelopes.

Verification

• Full suite: 6207 passed, 38 skipped; ruff check + format clean.
• Cloud catalog sweep (3,699 classes): classes whose fresh add-node layout ≠ set-widget indexing 41 → 0; 85 auto-grow groups (45 nested, 40 top-level) resolvable at the default selection.
• Report's repro commands with the real catalog: Nano Banana 2 image_1 / base / image_3 ✓, image_9 → "use the next free key model.images.image_4"; MiniMax template image_2 / image_3 / base ✓, LoadVideo → reference_videos.video_1 ✓, LoadVideo → reference_images → type mismatch … its slots take IMAGE; widgets stay […, 42, 'randomize', False]; widget-catalog MiniMax = 8 names, NB2 = 11.

Not in this PR (other children of the umbrella)

• Agent tool surface (services/agent … digest.go, list_slots, connect description) — the CLI half is done: nodes show now carries the names; the digest must keep dynamic_options / element_type / wire_as.
• comfy-knowledge canon rows "agent tooling cannot wire a Load Image to a slot that is not there yet" (nano-banana.yaml, seedream.yaml) — retract.
• In-repo follow-ups: nested groups with min > 0 (Grok / Qwen / HappyHorse) aren't checked by _check_autogrow_required; grown slots carry no label / shape (the frontend recomputes them on load).

Rollout note

Same as #809: the catalog hash changes (41 classes), so minted workflow_docs need a re-mint when the pin reaches an env with documents.

Changes

The PR adds schema-driven nested autogrow support for dynamic-combo nodes. It unifies widget traversal and serialization, resolves slots from active schemas, validates types and limits, and adds CLI and workflow-operation coverage.

Nested autogrow workflow support

Layer / File(s)	Summary
Widget traversal and autogrow metadata comfy_cli/cql/engine.py, tests/comfy_cli/cql/test_nested_autogrow.py, tests/comfy_cli/fixtures/object_info_nested_autogrow.json	Shared traversal now handles dynamic-combo selections, link-only inputs, widget defaults, autogrow groups, and serialized schema metadata.
Schema-based workflow resolution comfy_cli/workflow_ops.py	Workflow operations resolve nested and top-level autogrow groups from the destination node schema, reuse free slots, validate types, reject invalid sequences, and enforce maximums.
Nested autogrow validation and documentation tests/comfy_cli/command/test_workflow_edit_nested_autogrow.py, tests/comfy_cli/cql/test_nested_autogrow.py, CHANGELOG.md	Tests cover CLI wiring, replay, API conversion, widget ordering, selection-dependent groups, validation, and payload metadata. The changelog documents the related fixes and generate output format.

Merge Risk: 🔵 Low · up to b9815

This change enables nested dynamic autogrow connections, but conflict detection can still misidentify distinct nested groups as the same target, potentially preserving conflicting connections. The PR is otherwise mergeable with owner awareness and a localized follow-up to correct nested target handling.
