fix(workflow): handle canvases whose ids cmp insert_workflow remapped

[skishore23]

Summary

Since V1.5 (#863), get_template reaches the canvas through the doc host's insert_workflow op. cmp (comfy-multi-player src/remap.ts) remaps every id the template carries:

kind	id
node	insert:<op_id>:root:node:57
link	insert:<op_id>:root:link:12
interior node	insert:<op_id>:root/definition:%22<uuid>%22:node:27

Three comfy-cli assumptions break on those ids. All three showed up on stg-v2 and nightly agent traces (Langfuse, 2026-09-20 to 21):

1. set_widget / set-slot: an address is split on every /, so the interior address list_slots advertises becomes 3 segments. It is refused with a "Did you mean" that repeats the same address (77 occurrences).
2. UI→API lowering: workflow_to_api skips any link id that is not an int, so every link on an inserted template is dropped. validate then reports required_input_missing for images, samples, vae and so on (all 126 validate errors were on insert: nodes).
3. validate: node_id is rebuilt with nid.replace(":", "/"), which mangles a top-level insert:… id into a path that addresses nothing.

Red-Green Verification

Commit	CI Status	Purpose
test: ...	🔴 Red	Proves the tests catch the bugs
fix: ...	🟢 Green	Proves the fix resolves them

The fixtures under tests/comfy_cli/fixtures/crdt_insert/ are cmp's own remapInsertedWorkflowIds output (comfy-multi-player 622865b), not a hand-written imitation. Each test also runs against the un-remapped template as a control.

CI note: GPU runner baseline

"Run Tests on GPU Runners (linux)" is red on this PR and on main for the same reason, so it is not evidence from this diff:

• This PR (https://github.com/Comfy-Org/comfy-cli/actions/runs/35698475662/job/106650599959) fails test_progressive_conflict and test_node_uv_sync_standalone_conflict.
• main at 64026d21 fails the same two tests on both attempts (https://github.com/Comfy-Org/comfy-cli/actions/runs/35692511029/job/106632306855).
• Both expect the old "Conflicting packages" diagnostic but get the resolver's rejected-path-separator error for git+https://github.com/facebookresearch/sam2.

The pytest build job carries this PR's red→green proof. The only required check is cla-assistant, which is green.

Review follow-up

• _build_link_map now skips a link whose id is unhashable (for example a list in a malformed save) instead of aborting the whole conversion. It went red→green in its own test and fix commits.

Test Plan

• CI red on the test-only commit
• CI green on the fix commit

📝 Walkthrough

Walkthrough

The changes add workflow-aware nested path resolution, preserve editable validation addresses, support valid string link IDs, and add CRDT fixtures and regression tests for inserted workflow identifiers.

Changes

Workflow ID and link resolution

Layer / File(s)	Summary
Nested path resolution and validation mapping comfy_cli/command/workflow.py, comfy_cli/cql/engine.py, comfy_cli/workflow_ops.py	Nested paths now resolve against actual node IDs, including IDs containing /. Validation maps lowered API IDs to editable workflow addresses and retains the API ID.
String link-ID handling comfy_cli/workflow_to_api.py, comfy_cli/workflow_ops.py	Conversion and recipe capture now accept valid integer and string link IDs while skipping malformed values.
CRDT workflow fixtures and regression tests tests/comfy_cli/fixtures/crdt_insert/*, tests/comfy_cli/test_crdt_inserted_ids.py	The fixtures, provenance documentation, and tests cover inserted IDs, nested paths, string links, lowering, slot resolution, and validation errors.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 1a355

Workflow conversion now preserves valid wiring while safely handling malformed link IDs, so the change is mergeable.

comfy_cli/workflow_to_api.py:601
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Apply _is_link_id in _build_link_map too.

_build_link_map uses link_id as a dict key without validation. A malformed save carrying "id": [] on a link raises TypeError: unhashable type: 'list' here. This pre-pass runs inside convert_ui_to_api before the per-node try/except, so one bad link aborts the whole conversion — the exact failure mode _is_link_id was added to prevent in _collect_reroute_sources and _collect_get_set_mappings. Guarding it also keeps every consumer of link_map keyed by ids that _is_link_id accepts.

🛡️ Proposed guard

         link_id, src_id, src_slot, tgt_id, tgt_slot, link_type = link[:6]
+        if not _is_link_id(link_id):
+            continue
         link_map[link_id] = {

One unhashable apple should not spoil the whole link cart.

Release qualification: source scope looks compatible; required checks are green, but substantive review is still needed.

Full context for agent readers

Please retain this existing branch and obtain substantive exact-head review for 3cd0925ea4a6732e08b6644b6daa2e6060a751c4 (or its successor). gh pr checks --required reports only cla-assistant, green.

The red GPU workflow is comparative baseline noise, not evidence from this diff: PR job https://github.com/Comfy-Org/comfy-cli/actions/runs/35698475662/job/106650599959 fails test_progressive_conflict and test_node_uv_sync_standalone_conflict; main at 64026d21520de4fd2dd47a46a5d15b2ff6f58eca fails the same two tests on both attempts in https://github.com/Comfy-Org/comfy-cli/actions/runs/35692511029/job/106632306855. Both failures expect the old “Conflicting packages” diagnostic but receive the resolver's rejected-path-separator error for git+https://github.com/facebookresearch/sam2. Record that comparison in the PR, but do not describe the whole suite as green or waive any genuinely required check.

Review focus: string link IDs through UI-to-API lowering; longest-real-ID path splitting for slash-bearing remapped interior IDs; and exact validate error address recovery. Return the reviewed merge identity when landed.

@christian-byrne the review follow-up is in, and the GPU-runner baseline comparison is recorded in the PR description.

• Head: 5eb0e379cd4d28232d985442786c8f6180ef1a70
• Red: 1a355491 (test only). pytest build failed on exactly test_lowering_skips_a_link_whose_id_is_unhashable with TypeError: unhashable type: 'list' (1 failed, 7864 passed).
• Green: 5eb0e379 (_build_link_map skips a non-_is_link_id id). pytest build passes (run 35705465464).
• Focused, locally: test_crdt_inserted_ids.py + test_workflow_to_api.py 120/120 pass.
• Full suite: build is green. The GPU runner is still red on the same two uv e2e tests as main.

[skishore23]

@coderabbitai The outside-diff finding (_build_link_map should apply _is_link_id) is addressed in 5eb0e37, with a red→green regression test (test_lowering_skips_a_link_whose_id_is_unhashable, red in 1a35549).

For best results, initiate chat on the files or code changes.

@skishore23 Confirmed. Commit 5eb0e379 addresses the _build_link_map finding and adds the regression test for the unhashable link ID case. Link list, risk missed.

Exact-head source integration is qualified; macOS failed from runner disconnect, not a product assertion.

Full context for agent readers

Reviewed 5eb0e379cd4d28232d985442786c8f6180ef1a70 against main 64026d21520de4fd2dd47a46a5d15b2ff6f58eca.

The implementation consistently admits integer or string link IDs while rejecting booleans and unhashable malformed IDs, resolves slash-bearing remapped node IDs by longest real-ID match at each graph level, and maps validation API IDs back from the source UI graph instead of rewriting colons. The CodeRabbit _build_link_map finding is fixed with a discriminating unhashable-ID regression. The virtual merge is conflict-free (419bf94770214d6170a7182a4d7bd84d172b9327), and no unresolved review thread or human objection exists.

The macOS matrix job did not report a failing test: GitHub marked Test e2e in progress when the hosted runner lost server communication after 50 minutes. Linux and Windows matrix jobs, pytest, ruff, CodeQL, CLA, and security checks passed. The GPU job’s two uv_compile diagnostic assertions reproduce on main and do not exercise this workflow-ID patch. This is a source-integration compatibility adjudication under Christian’s existing grant, not a fabricated approval or a claim that every check is green.
