The loader of ComfyUI logs one line per yaml entry. The host already printed that block at its startup, so the pack raises the level of the root logger while it asks the host to read the file again - the block is not printed a second time.
ComfyUI reads the default extra_model_paths.yaml and every file of --extra-model-paths-config (main.py:142-144). The pack now follows the same list, so a user who supplies the extra roots only on the command line gets the layout convention as well and the checkpoint is found where it is instead of being downloaded again.
The download target was always the primary root, so a checkpoint that already existed in the original model directory was downloaded again into the dev instance. The extra roots of extra_model_paths.yaml are now registered for the folders of the pack (the explicit keys through the loader of ComfyUI itself, the layout convention base_path/models/folder), and a missing weight is downloaded next to the other weights of the pack.
The five review findings of 2026-10-23 for phase P5:
1. The P5.5 fallback branch (a checkpoint without flownet.* keys) died with
a bare RuntimeError at the strict load: the arch always owns the flownet
(keep_arch.py:882), so the state dict of the net always carries the
flownet.* keys - and the GMFlow weights the arch had just loaded were
discarded. The flownet tensors of the built net (the trained ones - the
arch was built with flownet_path) are now merged into the checkpoint
state dict before load_state_dict(..., strict=True). The load stays
strict (an unexpected key still raises) and the trained flow weights
survive. The stub arches of the tests behave like nn.Module now - a
no-op recorder had hidden the defect.
2. P5.4's acceptance is no longer unmet: the GPU acceptance run was
executed (real weights, real ComfyUI modules, RTX 4070 Ti SUPER) and is
green (5 passed, exit code 0; the run log is in the audit doc section 5).
KEEP_MODEL_DIR now really decides where the weights come from - it is the
models root of the run (folder_paths.models_dir), the harness fixture
no longer isolates the gpu_acceptance tier, and the run needs
KEEP_NO_COMFY_MOCKS=1 so the real ComfyUI modules are in charge.
3. The "the flow weights are not random" assertion of the acceptance test
could not distinguish random weights from trained ones. It now compares
the flownet tensors with the tensors of their source (the KEEP checkpoint
or the GMFlow file) bit for bit.
4. The superseded download helper load_file_from_url_comfy is gone
(src/keep_paths.py only resolves paths; the download lives in
src/keep_download.py since P5.2). The stale docstrings, the stale
comment in the vendored facelib and the two tests that called the dead
helper are fixed.
5. The risk list mentioned a pending deletion of assets/keep-preview.png
that does not exist - the asset is committed and present (93279 bytes).
The rule in the implementation workflow now states the truth.
Checks: the gate (pytest -q -m "unit or mock_integration") is green (234
passed, 1 skipped, 1 xfailed); the opt-in acceptance run is green (5 passed);
the acceptance tier still skips cleanly without its environment variables.
Five review findings of the P3 phase, each fixed at its root:
1. (medium) The P3.7 metadata test imported `tomllib` at module level: the
**3.10 CI job** (the declared `requires-python >=3.10` minimum) died
during collection, so the registry-metadata assertions never ran on 3.10.
The parser import is now guarded (`tomllib` -> `tomli`, the package the
3.10 job installs); without any parser the module *skips* instead of
dying. `pyproject.toml` gained the test extra
`tomli>=2.0; python_version < '3.11'`.
Proof: a 3.10 simulation (the stdlib `tomllib` refused for the test
module, `tomli` on sys.path) -> 6 passed; the control without `tomli`
-> 6 skipped (no collection error).
2. (medium) The P3.5 "primary-root-first multi-root" resolution was not
wired into the production load path: `resolve_model_file` (the only
`get_full_path_or_raise` caller) was used by tests only, so a weight in
a secondary model root was downloaded into the primary root again.
`src/keep_paths.py` now has `find_model_file()` (the multi-root lookup
through `folder_paths.get_full_path_or_raise`) and `resolve_model_root()`
(the root the weights really live in); `load_file_from_url_comfy()` - the
production path of `src/keep_model_loader.py:107` - uses the lookup, and
the facelib root follows the weights (the facelib helper builds its
paths from a single root). New tests prove that the production path
uses a weight of an extra model root and that the primary root wins.
The `models_dir` grep guard is no longer a blanket exemption: only the
registration in `src/keep_paths.py` may use the attribute.
3. (low) `[tool.comfy].Icon` was an empty string and the test only checked
that the key exists. The preview asset **is** committed
(`git cat-file -s HEAD:assets/keep-preview.png` -> 93279 bytes); only the
working copy was missing (an uncommitted local deletion, restored from
HEAD - no asset change is in this commit). The key now points at
`assets/keep-preview.png` and the test asserts that the value is not
empty and names a file that is really in the repository.
4. (low) `tests/test_package_entrypoint.py` hard-coded the V1 state and
would have gone red (not xfail) when P4.4 flips the root `__init__.py`
to `comfy_entrypoint`. The assertions now follow the entry point that is
really there: exactly **one** mapping style (V1 XOR V3). The mocked
smoke test of `tests/test_package_import.py` got the same treatment; the
headless variant is P4.4's job (its test list names it).
5. (low) The plan's §3 rule ("`comfy.*` imports inside `src/` are lazy
(function-level) so the pack imports without a ComfyUI server") was
violated and unguarded. The `comfy` imports of `src/keep_model_loader.py`
and `src/keep_processor.py` are function-level now; the vendored facelib
helper (which imports `comfy` itself) is imported lazily through a module
`__getattr__` (PEP 562), so `loader.FaceRestoreHelper` still resolves to
the vendored class. Structure **guard (f)** (`tests/test_structure.py`)
forbids a module-level `comfy`/`comfy_api` import in `src/**` (with the
self-test the guards file demands), and the new
`tests/test_lazy_imports.py` proves at runtime that the engines import
while every `comfy` import is blocked.
