…sed/) Three parked fixtures with dual-implementation observations: center() odd-padding and ASCII-only isdigit() are spec gaps where BOTH implementations agree (no divergence - the spec should document the de facto behaviour), and repr_py raw-newline emission is a bug in BOTH implementations per the explicit spec text. Details in proposed/README.md. Companion to conformance-func-lib-gaps. Signed-off-by: David Leong <116610336+leongdl@users.noreply.github.com>

Important
Expected-failure / spec-question fixtures — do not expect these to pass. Parked in
EXPR/proposed/(not discovered by the runner). Each asserts a strawman expectation and must not move intojobs/until the spec question beside it is resolved or the bug is fixed. Details inproposed/README.md.Contents (3 fixtures, dual-implementation verified)
expr2.2.6--repr-py-newline-roundtrip— implementation bug in BOTH implementations:repr_py("a\nb")emits a raw newline inside the quotes (invalid Python literal;ast.literal_evalraises SyntaxError). §2.2.6 is explicit thatrepr_pyfollows Python'srepr, which escapes. Move tojobs/once fixed.expr2.2.4--center-odd-padding— spec gap, NO divergence: both implementations put the odd pad space on the RIGHT (matching Pythonstr.center). §2.2.4 is silent on the split. The spec should document the de facto behaviour; then this fixture (with corrected expectation) goes live.expr2.2.4--isdigit-unicode— spec ambiguity, NO divergence: both implementations returnfalseforisdigit("٣")(ASCII-only digits). §2.2.4 leaves "digit" undefined while §2.2.5 gives\dexplicit Unicode semantics. Note the Python openjd CLI here deviates from native Pythonstr.isdigit. The spec must define "digit"; the de facto agreement is ASCII-only.Companion to the green-fixture PR from branch
