Auto-grow repeated-edit paths: CLI holes vs FE compaction — replace_ops round-trip now pinned; found + flagged a real apply_specs gap.

Full context for agent readers

Context: [Triage BE-10726] "Auto-grow repeated-edit paths — CLI leaves holes where FE compacts; cover replace." The CLI's repeated edits on autogrow bases leave sparse slot numbering (images.image0 + images.image2, no image1) where the FE compacts naming; the row asks the replace (bulk-writer) path to be covered.

What this PR does (tests only, no runtime change):

  1. Op path fidelity: replace_ops + apply_op reproduces a contiguous (FE-compacted) autogrow canvas verbatim — names, wiring, link count.
  2. Holed-canvas fidelity: a faithful holed canvas (sparse NAMES, dense slot array — the FE keeps the inputs array packed, only element numbering gaps) replays verbatim. The replay neither renumbers grown slots (silent compaction the CLI never performed) nor mints a gap-filled duplicate for the hole. This pins "CLI leaves holes where FE compacts" as intentional, reproducible-through-replace behavior.
  3. Found while covering: apply_specs CANNOT replay any replace_ops batch that wires an autogrow slot — holed or contiguous. replace_ops mints connect spec refs as $alias. (_slot_ref deliberately avoids dotted names), but apply_specs re-mints each node from the live catalog, so the fresh BatchImagesNode has only the bare images input and the index refs resolve to nothing → ValueError → the whole batch discards (abort-remainder). The §8.8 "one artifact, both consumers" contract is broken for all autogrow wiring. Invisible until now: the only existing replace_ops test (test_deprecated_nodes.py::test_replace_ops_apply) used a link-less workflow. Pinned as a strict xfail rather than fixed here — changing the frozen mint semantics (e.g. base-addressed refs ordered by to_slot, which would compact holed canvases on the spec path) is an owner decision per the amendment discipline in docs/op-vocabulary-v1.md §9.

Reviewer note: assignee is christian-byrne only (quiet week through 2026-09-06 — no teammate assignees/reviewers/mentions).

Evidence

Commands run (worker VM, comfy-cli @ origin/main 3fddc3e + this commit):

  • pytest tests/comfy_cli/command/test_workflow_edit.py -q -k "replace_ops or autogrow or p9" → 16 passed, 1 xfailed (the strict pin, as intended)
  • pytest tests/comfy_cli/command/test_workflow_edit.py tests/comfy_cli/command/test_deprecated_nodes.py -q → 131 passed, 1 xfailed
  • pytest tests/comfy_cli -q --ignore=tests/comfy_cli/command → 2158 passed, 5 skipped, 1 failed — the failure is test_file_utils.py::test_atomic_write_text_new_file_uses_umask_default, verified failing identically on a clean origin/main worktree on this host (worker umask baseline, pre-existing, unrelated)
  • ruff check + ruff format --check on the touched file → clean
  • Spec-path defect reproduced directly: apply_specs of a replace_ops batch wiring 3 autogrow connects raises ValueError: input '1' not found on node …; inputs: ['images'] and discards the batch; apply_op of the same batch wires all 3 slots with names verbatim.

…ply_specs gap (BE-10726)

The CLI's repeated autogrow-edit paths leave sparse slot numbering where the
FE compacts. Cover the replace_ops bulk-writer path for both shapes:

* op path (apply_op) reproduces contiguous and holed autogrow canvases
  verbatim — grown slot names are never renumbered and no gap-filled
  duplicate is minted.
* spec path (apply_specs) is pinned as a strict xfail: replace_ops mints
  connect spec refs as $alias.<slot index>, which cannot resolve on nodes
  apply_specs re-mints from the live catalog, so ANY replace_ops batch that
  wires an autogrow slot discards wholesale. The only prior replace_ops
  test was link-less, so the §8.8 one-artifact/two-consumers gap was
  invisible. Left for an owner ruling rather than silently changing the
  frozen mint semantics.

📝 Walkthrough

Walkthrough

Changes

This change adds regression coverage for replace_ops replay on autogrow canvases. It checks contiguous and sparse slot names, links, and wiring. It also records the current apply_specs replay limitation.

Autogrow replacement replay

Layer / File(s) Summary
Canvas helpers and replace_ops replay tests
tests/comfy_cli/command/test_workflow_edit.py
Added helpers and tests for contiguous and sparse autogrow slots. The tests verify slot names, link counts, and wiring without renumbering or gap filling.
apply_specs limitation coverage
tests/comfy_cli/command/test_workflow_edit.py
Added a strict expected-failure test for replaying autogrow references through apply_specs.

Merge Risk: 🟡 Moderate · up to 55598

This test-only change adds replay coverage but can report correct autogrow wiring when source connections are wrong and can mask unrelated failures in the expected-failure case. Tighten the topology assertions and constrain the expected exception before merge.

Assert the source-to-slot wiring in both replay tests.

Both tests only verify slot names, whether slots are linked, and the link count. A replay that swaps the sources for images.image0 and images.image2, or maps every slot to one valid source, still passes. Compare normalized link topology, such as slot name plus source-node position and output index, between doc and new.

  • tests/comfy_cli/command/test_workflow_edit.py#L2228-L2229: compare contiguous source-to-slot wiring, not only linked-state and count.
  • tests/comfy_cli/command/test_workflow_edit.py#L2286-L2291: compare sparse source-to-slot wiring, including the image0 and image2 mapping.

Restrict the expected failure to ValueError.

strict=True rejects an unexpected pass, but without raises any exception can be treated as an expected failure. Add raises=ValueError so unrelated failures remain visible.
