* Studio: split model-load progress label across two rows
The chat flow and training overlay both compose a progress label like
"112.6 of 122.3 GB • 331.0 MB/s • 30s left" and render it next to the
percent badge in a single flex row. Once the rate + ETA part shows up,
the label outgrows the row width and wraps mid-phrase, orphaning the
percent ("19 left %") onto a second ragged line.
Fix in model-load-status.tsx: split the label on the first " • " into
a primary (size) chunk that stays on row 1 with the percent, and a
secondary (rate/ETA) chunk that renders on its own muted row below.
Labels without a bullet (e.g. "22.8 GB downloaded") collapse cleanly
to one row. The inline-status variant keeps only the primary and
surfaces the full label via the tooltip.
Also extracts the rate/ETA math out of useTransferStats into a pure
``transfer-stats.ts`` module (appendSample + computeTransferStats) so
it can be reasoned about and tested without React. The hook is now a
thin wrapper that feeds sample history through the pure functions.
Backend: adds two companion test files for load_progress():
* test_llama_cpp_load_progress_matrix.py (21 tests) -- platform
matrix (Linux /proc, macOS/Windows absence), VmRSS parsing
variants (tab/space/missing/malformed), filesystem edges (HF-cache
symlinks, broken symlinks, nonexistent paths, relative paths),
shard aggregation (partial multi-shard, two series in same dir,
mmproj-* exclusion, single-file), lifecycle races, concurrent
sampling (10 threads x 50 iters against real /proc), fraction
bounds.
* test_llama_cpp_load_progress_live.py (5 tests) -- no-mock live
integration: real subprocess allocating 100 MB to match VmRSS,
real ready phase, real dead-pid degradation, real shard
aggregation, repeated polling. Skipped on non-Linux.
Both complement the existing test_llama_cpp_load_progress.py.
