TurboFieldfare 0.2.1 — Resumable Model Downloads

TurboFieldfare 0.2.1 makes the model download resumable in the Mac app and
command-line installer. Completed ranges survive cancellation or process
interruption and are revalidated before reuse.

Resumable model downloads

• The Mac app can resume or discard a saved download and reports reused bytes,
  current progress, and estimated time remaining.
• The installer adds --resume and --discard-partial commands.
• A compact checkpoint binds saved ranges to the source revision and copy plan.
• Resume verifies saved destination digests and downloads only missing or
  damaged ranges.
• Exact HTTP range validation, bounded temporary storage, retries, a
  physical-target lock, final verification, and atomic publication protect the
  installation.

Continue from the command line

swift run -c release TurboFieldfareRepack \
  --output scratch/gemma4.gturbo \
  --overwrite \
  --resume

To remove a saved download:

swift run -c release TurboFieldfareRepack \
  --discard-partial \
  --output scratch/gemma4.gturbo

Validation

• A release installer killed after three durable ranges resumed with
  200,228,864 bytes reused and completed all 223 planned ranges with zero
  retries.
• Final verification passed 37 files and 14,291,915,755 bytes.
• The public serial test suite passed 509 tests in 108 suites.

This is a source-only release. It does not include model weights or application
binaries.
