Refreshes the checked-in size baselines and 3% ceilings from all four platform reports produced by canary CI run 31919654825 at source SHA e8c6ef36ac644dfebd6301227c9258bd7d646532.

The macOS baml-cli grew to 22,259,408 bytes after #4451, exceeding the old hard ceiling by 29.6 KB and the relative 3% gate by a rounding margin. The repository-owned cargo size-gate bake command regenerated all platform baselines and ceilings from that single provenance-bound run. The matching checked-in ceiling assertion is updated from 21.2 MiB to 21.9 MiB.

Validation: cargo test -p cargo-size-gate; cargo fmt --check -p cargo-size-gate; git diff --check.

📝 Walkthrough

Walkthrough

The PR raises size-gate ceilings for baml-cli and packed-program, refreshes platform artifact-size records and build metadata, and updates the macOS configuration test expectation.

Changes

Size-gate refresh

Layer / File(s)	Summary
Thresholds and validation baml_language/.cargo/size-gate.toml, baml_language/crates/tools_size_gate/src/config.rs	The size-gate ceilings and the macOS max_file_bytes test expectation are increased.
Platform baseline records baml_language/.ci/size-gate/*	Platform timestamps, Git SHAs, artifact measurements, and obsolete CI-record comments are updated. baml-cli, packed-program, and bridge WASM baselines change where applicable.

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

Merge Risk: ⚪ Minimal · up to 8477e

The PR refreshes size-gate baselines and ceilings without changing product runtime behavior. No actionable merge-blocking risk remains after normal validation, though the library-only Rust test command should be explicitly confirmed before merge.

Poem

A rabbit checks each measured byte,
And nudges ceilings left and right.
The build records hop in line,
With fresh timestamps, neat and fine.
The size gate rests, its numbers true.
