- PromptRefiner unload_model toggle now actually controls eviction:
keep_alive is "0s" when on, None (server default) when off, so the
UI no longer unloads against the user's choice.
- Cleanup always runs; unload fires only when unload_model is on AND the
subprocess fallback left a model loaded, instead of skipping cleanup
entirely when the toggle is off.
- release_vram() clears empty_cache() on every CUDA device, not just
device 0, for multi-GPU rigs.
- Add docstrings to INPUT_TYPES methods and language ids to plan doc
code fences.
The post-execution cleanup unconditionally called unload_model(), which
sends a generate request to evict the model. On the streaming-success
path keep_alive="0s" has already evicted it, so that request forced
Ollama to reload the model just to unload it again — a cold load+unload
cycle with a VRAM spike after every node run.
Track whether the subprocess fallback ran and pass unload=used_subprocess
to cleanup. The streaming path relies on keep_alive="0s"; only the
subprocess path (which carries the 5m default) still needs an explicit
unload. CUDA cache release continues to run on every path.
Pass keep_alive="0s" on every Ollama generate call so models are
evicted from GPU VRAM immediately instead of lingering 5 minutes,
which caused CUDA OOM when downstream diffusion models loaded.
Each node now runs async VRAM cleanup in a try/finally block. The
cleanup uses unload=True so it also evicts a model loaded via the
subprocess fallback path (which carries the default keep_alive).
Add unload_model(), release_vram(), cleanup() and cleanup_async()
to OllamaClient, plus a per-node unload toggle on PromptRefiner.
requires-python is >=3.10 but enum.StrEnum was added in 3.11, so the
combiner node (and thus the whole package) failed to import on 3.10 —
which is also why the Test CI job was red. Back-port StrEnum on <3.11
with matching str() semantics.
Require a colon separator and anchor the Negative label to a line
start so the word 'negative' in the positive prompt body (e.g. the
art term 'negative space') is no longer mistaken for a stream label.
Add regression tests.
Add PromptDualStreamRefinerNode that produces a positive and negative
prompt pair in a single pass via Ollama, intended for the shipped Q8
GGUF of qwen2-5-7b-dual-stream-prompt-lora. Reuses OllamaClient for
streaming, timeouts, progress, and llama-runner crash handling, and
parses Positive/Negative output defensively across label variants.
Includes config/Modelfile.dualstream, unit tests, node registration,
and a corrected implementation plan replacing the invalid local
transformers/PEFT approach.
Replace the catch-all RuntimeError wrapper in OllamaClient.generate_streaming
with a StreamResult dataclass that categorises failures (ok, timeout, transient,
model_crash, server_error, unavailable). Llama-runner crashes (HTTP 500 with
"runner terminated" / "exit status" / "load failed") are detected and surfaced
as user-actionable messages in the ComfyUI prompt output instead of bubbling
up as Python stacktraces.
PromptGenerator, NegativePrompt, and PromptRefiner nodes now branch on
result.kind: model_crash / server_error / unavailable surface the message
directly (subprocess fallback would also fail), while timeout / transient
fall through to the existing subprocess fallback path.
Adds 6 unit tests covering each error class plus the success path. Updates
the existing PromptRefiner seed tests to return StreamResult from mocks.
The absolute `from style_presets import StylePreset` failed at INPUT_TYPES()
evaluation because ComfyUI's loader does not reliably place the custom-node
directory on sys.path. Switch to `from ..style_presets import StylePreset`
with an absolute fallback for test/script-execution contexts, matching the
dual-mode try/except pattern already used in __init__.py.

The previous commit added files under custom_nodes/comfyui-prompt-generator/
which is the wrong structure for this standalone repo. The correct flat structure
(__init__.py and nodes/ at repo root) already existed. This removes the duplicate
nested copy.
Hardening release. No public API changes — same 5 NODE_CLASS_MAPPINGS
keys as v1.3.0. The bump exists so the registry can serve a build that
includes the version-tag guard, the registration contract tests, the
mapping drift self-check, the modernized typing, and the CI fixes.

Direct response to the v1.1.x → v1.3.0 silent-skip pattern, where
pyproject.toml was bumped four times without ever pushing the matching
git tag, so .github/workflows/publish.yml never fired and the registry
stayed on v1.1.6.
- scripts/check_version_tag.py: stdlib-only (tomllib) script that fails
if pyproject.toml's version has no matching git tag locally.
- .pre-commit-config.yaml: wires ruff (check + format) and the local
version-tag-guard hook. The guard fires only on pyproject.toml edits.
- test.yml: new verify-tag-exists job that fails the main-branch build
when pyproject.toml's version has no matching tag in the repo. Belt
and suspenders for the pre-commit hook.
- test.yml validate job: same comfy-cli telemetry fix already applied
to publish.yml; suppresses the interactive opt-in prompt in CI.
- pytest.ini + test.yml: lower coverage gate from 70 (never enforced;
failed on every main push since chain nodes were added) to 50 (the
actual current floor). Comment marks it as a starting point for
future test growth.

Direct response to the v1.1.6 packaging gap, where the prompt-chain nodes
(combiner, refiner, negative) were authored under nodes/ but never wired
into NODE_CLASS_MAPPINGS, so they silently failed to ship.
- __init__.py now raises RuntimeError at import time if NODE_CLASS_MAPPINGS
and NODE_DISPLAY_NAME_MAPPINGS drift apart. ComfyUI startup logs surface
the mismatch instead of dropping the node from the menu silently.
- New tests/unit/test_node_registration.py contract suite (8 tests):
* Expected 5 keys are registered.
* Display names cover every class.
* Each registered class satisfies the ComfyUI node interface
(INPUT_TYPES classmethod, RETURN_TYPES, FUNCTION, CATEGORY,
and the FUNCTION attribute resolves to a callable method).
* Every nodes/*_node.py module on disk is reachable from the mapping —
this is the regression guard that would have caught v1.1.6.

Changes:
- Add [tool.ruff] config with target-version py310 and a curated rule set
(E/F/W, I, UP, B, SIM, RUF) so future drift is caught in CI lint.
- PEP 585 sweep across all node modules: drop legacy typing.Dict / List /
Tuple / Optional in favor of dict / list / tuple / `X | None`. Annotate
class-level mutable defaults as ClassVar to satisfy RUF012.
- PromptCombinerNode: replace the magic-string mode chain with a CombineMode
StrEnum + match statement. The dropdown choices in INPUT_TYPES are now
derived from the same Literal alias used in the function signature, so the
UI and the type contract can't drift apart.
- Smoke tests for PromptCombinerNode (14 tests) covering enum mapping, all
three modes, edge cases, and the unknown-mode error path. Brings combiner
coverage from 28% to 96%.
- Tidy preexisting issues surfaced by the new lint rules: B904 except chaining
in style_presets, RUF013 implicit Optional, RUF059 unused unpack, SIM117
nested-with consolidation in tests.

comfy-cli removed the implicit env-var lookup and the --confirm flag.
The new contract is: pass the token via --token, and gate publishing
on a clear preflight check so CI failures point straight at the
missing secret instead of a typer "No such option" message.

The first invocation of comfy-cli in CI hit the interactive
"Do you agree to enable tracking?" prompt and aborted. Run
'comfy --skip-prompt tracking disable' before validate/publish
so the workflow runs unattended.
