-# --- KNOWN COMPATIBILITY RISK (read before deploying) ---
-# This build was written and unit-tested in a sandbox running numpy 2.4.4
-# and pandas 3.0.2 — newer than the numpy<2 pin uni2ts's own dependency
-# chain (jax/lightning) has historically required. `pip install uni2ts`
-# will resolve numpy down to whatever it needs; the numpy<2 pin above
-# reflects that expectation. If the uni2ts release you install supports
-# numpy 2.x, relax this pin. Verify with:
-#     pip install -r requirements.txt
-#     python -c "from uni2ts.model.moirai_moe import MoiraiMoEModule; \
-#                 MoiraiMoEModule.from_pretrained('Salesforce/moirai-moe-1.0-R-small')"

+# --- FIX applied after a real HF Spaces build failure ---
+# An earlier version of this file pinned `numpy<2.0` and an explicit
+# `scipy>=1.11` as an untested precaution. On a real Spaces build this
+# forced pip to resolve an old scipy release with no prebuilt wheel for
+# the Space's Python version, which then failed trying to build scipy
+# from source via meson (no Fortran compiler / BLAS-LAPACK toolchain in
+# that install step -> "metadata-generation-failed"). Neither pin was
+# load-bearing: nothing in this codebase imports scipy directly, and
+# none of our own numpy usage requires numpy<2. Removing both lets
+# uni2ts/gluonts/torch resolve numpy (and scipy, transitively) to
+# whatever versions they actually ship wheels for.
+#
+# General pattern if a DIFFERENT package fails "metadata-generation" or
+# tries to build from source on Spaces: it's almost always pip being
+# forced into a source build for a package with no wheel for that
+# Python version. Fix is usually the same shape -- stop pinning that
+# package explicitly (or bump its floor) and let its real dependent
+# choose a version it has a wheel for.
