Done, in 7c7de9a — this thread is outdated. The requirement names an immutable commit rather than the branch, in the root extra and in all four requirements here, with both lockfiles regenerated. tests/test_dependencies.py::test_docs_app_pins_the_same_reflex_commit keeps the six strings in step, since uv refuses two URLs for one package and a half-updated pin would otherwise only surface as a resolution failure in a separate job. Currently b8580ed1337487671569d5964ea362296005d8fa.

Does not reproduce — skipping, with the evidence.
_step_direct_key_values collects every matching direct key into a list and reports unsafe for any unsupported spelling at that indent; the caller then requires not unsafe and values == ["always()"]. So both halves already fail closed. Ran all three shapes against the real validator:
| mutation | caught |
|---|---|
if: always() + a second if: failure() |
yes — values == ["always()", "failure()"] |
if: always() + "if": failure() (quoted equivalent) |
yes — _decode_yaml_key normalizes it, same duplicate list |
if: always() + "\x69f": failure() (YAML-only escape) |
yes — _decode_yaml_key fails closed, unsafe=True |
Switching to _direct_yaml_key_values would be a regression here: it takes a fixed indent and uses _direct_yaml_mapping for every line, so it cannot read a step's first line, where the key sits behind the - sequence indicator at indent+2. _step_direct_key_values handles that case via _sequence_item_yaml_mapping, which is why it exists.
The sibling finding on line 554 was real and is fixed in 62ebcf3 — duplicate step names were the actual ambiguity.
