What changed

• Refresh all eight C# native asset baselines from the exact artifacts produced by release run 31925845745 at source 4b08255ca0142419bf500d3007c1b84b86242cdc.
• Update the reviewed evidence to the reproduced 75,118,828-byte deterministic NuGet package.
• Keep the compressed-package regression baseline and 200 MB registry safety ceiling unchanged.

Why

The 0.17.0 release verification failed because every native target had grown slightly beyond the stale July baseline plus its 10% budget. The first reported failure was Apple ARM64: 23,777,024 bytes against a 23,495,683-byte ceiling. Publishing remained blocked behind the all-builds gate.

Validation

• Reproduced package assembly locally from all eight provenance-bound artifacts from run 31925845745.
• Both normalized NuGet builds produced SHA-256 c37be3d9257070bb19034c5262f9a9ec30d9c5e05dbbb0a1ec1145e366e8d3ee.
• Package size is 75,118,828 bytes, below the unchanged 80,500,000-byte regression ceiling.
• python3 scripts/tests/test_release_pipeline_contract.py (26 passed)
• jq empty release/csharp-package-size-policy.json
• git diff --check

📝 Walkthrough

Walkthrough

The C# package size policy now records newer measurement evidence and larger compressed native payload baselines for all eight target platforms.

Changes

C# package size policy

Layer / File(s)	Summary
Refresh size evidence and baselines release/csharp-package-size-policy.json	The policy now records a newer workflow run, source commit, measurement date, compressed native payload size, and per-platform native asset byte counts.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to 54aa7

This refreshes package-size baselines while keeping the regression ceiling unchanged; the reported validation passes, and no actionable merge-blocking risk remains after normal checks and review.

Poem

A rabbit checks the numbers twice,
New size records sparkle nice.
Eight platforms hop in line,
With fresh baselines, neat and fine.
“Package policy,” cheers the hare!
