140-140: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winCompare the legacy definition-group ID with a fresh insert.
The current assertion checks only that the projected definition-group ID is a positive safe integer. A wrong definition scope or numeric mapping can pass. Use the definition scope from
remap.tsand compare the projected legacy ID with the ID from a fresh insert of the same definition group.Suggested fix

risk:R1
ComfyUI_frontend's workflow schema declares groups[].id as z.number(), at the root and inside definitions.subgraphs[].groups, and refuses the whole workflow when one is a string: Invalid workflow against zod schema: Expected number, received string at "definitions.subgraphs[0].groups[0].id" remap.ts gave groups the string derivedId every other kind gets, so any insert_workflow that carried groups projected a workflow the frontend rejects. The canvas then keeps its own copy of the graph and stops taking the document's projection, so later edits land in the document but never reach the canvas. Groups now take the links' numeric derivation (ADR-033): sha256 of the same string seed folded into [1, Number.MAX_SAFE_INTEGER], a pure function of the op's own content. The fold is shared as numericId(); link ids are unchanged. A document that already stores the string form reads back through the same fold in project(), so it projects the number a fresh insert of that op derives, and project -> mint -> project stays a fixed point. Numeric and absent group ids are untouched. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…replay Two group-bearing insert_workflow ops applied in either order project the same groups, with the same original id in each op kept distinct, and re-applying an insert is a no-op that leaves the projected groups unchanged. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Reviewed the numeric group-id derivation. The core approach (mirroring the existing link-id hashing for insert_workflow groups) is sound and the test vectors check out.
One finding that needs a fix before merge:
src/project.ts:330 — projectGroups() coerces any string-typed group id to a hashed number, not just ids matching this package's own insert:<opId>:<scope>:group:<original> derived format. Repro:
mint({ nodes: [...], links: [], groups: [{ id: "my-custom-group", title: "g", bounding: [0,0,1,1] }] })
project(doc, catalog) // group id silently becomes e.g. 3293296965306295Any workflow with a plain string group id that never went through insert_workflow gets its id silently replaced on every projection — breaks the project(mint(wf)) == wf round-trip for ordinary workflows. Suggest scoping the coercion to ids actually matching the derived-id pattern, same as the link path does.
Smaller note: the PR description draws a direct parallel to the KA-5 link-collision exception for this new group-collision risk, but docs/decisions/EXCEPTIONS.md isn't updated with a corresponding row + sunset date — worth adding alongside the fix above.
…id exception
projectGroups hashed every string group id, so a workflow's own string id
("my-custom-group") was replaced on every projection and project(mint(wf))
no longer round-tripped. Only the derived insert:<opId>:<scope>:group:<original>
form is coerced now. The legacy-id test now uses a realistic definition-scope
id, and EXCEPTIONS.md gets a PROPOSED KA-5 row for the group-id collision risk.

Re-reviewed after the fix. Both issues are resolved:
-
Main regression fixed.
projectGroupsnow only coerces a string group id when it matchesDERIVED_GROUP_ID(insert:<opId>:<scope>:group:<original>), which I confirmed matchesremap.ts's actual derivation format exactly, including scopes containing colons. Verified the original repro directly:DERIVED_GROUP_ID.test("my-custom-group")is nowfalse(left alone), while real derived ids still match and get coerced. Also backed by a new convergence test (group ids converge across arrival order and on exact replay). -
EXCEPTIONS.md updated. New KA-5 row for the group-id collision risk, mirroring the existing link-id row — and it goes further than I asked by honestly flagging that unlike links, a realized group-id collision on groups is not detected at all today (merged by content, not id), which is a useful disclosure for whoever picks this up later.
CI is green. Looks good to merge.

Problem
ComfyUI_frontend validates every workflow it loads, and its schema declares a group's
idasz.number().optional(), both at the root and insidedefinitions.subgraphs[].groups. A string id refuses the whole workflow:remap.tsgave groups the stringderivedId(insert:<opId>:<scope>:group:<original>) that nodes get, so anyinsert_workflowcarrying groups (at the root or in a subgraph definition) projected a workflow the frontend rejects. The canvas then keeps its own copy of the graph and stops taking the document's projection. Every later edit lands in the document but never reaches the canvas, and the next time the canvas pushes its state the two copies merge. That is how an old graph "comes back" and fresh edits look lost or duplicated.Links hit the same frontend constraint before (ComfyUI_frontend#18458) and were fixed with a numeric derivation (ADR-033). Groups were missed.
Fix
remap.ts: groups take the links' numeric derivation: sha256 of the same string seed, folded into[1, Number.MAX_SAFE_INTEGER]. It is a pure function of the op's own content (no document state), so replicas agree regardless of arrival order. The fold is shared asnumericId(), and link ids are byte-for-byte unchanged.project.ts: a document that already stores the old string id projects it through the same fold, so it reads back as the exact number a fresh insert of that op now derives. Numeric and absent ids are untouched, soproject → mint → projectstays a fixed point and ordinary workflows are unaffected.Red → green
New
test/insert-workflow-numeric-group-ids.regression.test.ts:expected 'string' to be 'number'expected 'string' to be 'number'test/insert-workflow.test.ts's pinned vectors for the raw group id now expect numbers. They were recomputed independently with a plainnode -e+ sha256 one-liner (in the test comment), without importing the remapper.Typecheck, eslint,
check:imports(23 modules / 74 deps, 0 violations),check:purityandcheck:pinspass. The full suite has the same failures asmainin my local checkout (environment-dependentstateless/portable-harness/check-stateless/purity npm ls).Residual risk
The same as links (ADR-033 / the KA-5 row in
EXCEPTIONS.md): two derived ids can coincide with ~2⁻⁵³-scale probability. Groups are matched by content, not id, in the applier's group merge, so a collision would at worst show two groups sharing an id on the canvas.🤖 Generated with Claude Code
