This pull request is bot-managed: it is regenerated on every push to main
and closes itself when no Version Plans are pending. Do not push to
release/next or enable auto-merge.
Merging this pull request publishes to npm. Prefer a squash merge with the
title unchanged; the release policy validates the commit either way.

8	2.258 ms	1.85 ms	8.356 ms	9
32	3.705 ms	2.898 ms	43.135 ms	33

Each route resolved exactly the listed sidecar count and produced byte-identical output. Timings are reported, not gated; replay's import cost is the documented N+1 worst case. The packed API has no import-attempt diagnostic, so native's one-import invariant remains gated by native tests.

Format matrix

Report-only: only a new crash fails this check. base 0484f06 against pr d27c81a, both measured on the same runner with their runs interleaved. Wall time is the median of the timed runs; a cell is slower or faster only when the two builds' runs do not overlap and the medians differ by at least 1.1x and 3 ms (small tier: 2.5x and 15 ms, where V8 tier-up timing dominates). "× gear" divides by the same build's helical-gear GLB round trip. "output" compares a SHA-256 over every output file ("varies" marks exporters that stamp the time). Small-tier RSS is the growth over the RSS the cell started from; large-tier RSS is the peak of a process that ran only that cell.
