Bootstrap: gen-0 sidecar stamp drift after StringJsonEncodeInventoryStubs spine edit (#14818) #14831
Description
Category
bootstrap | compile/link gate
Problem
#14818 added StringJsonEncodeInventoryStubs.php to test/selfhost/compiler_lib_spine_smoke/main.php but did not refresh prelinked/bootstrap-gen0/.m3_compiler_lib_sidecar.sha.
php script/check-selfhost-spine-sidecar-sync.php fails:
stamp 8943a5b93dd400e7700138463bd68b741886c801 ≠ spine entry SHA-1 e62d3ec969206c7e4e364eafed00dc9839590dee
make bootstrap-loop-probe M2 fails when sidecar fallback runs: bundle stdout crashes (free(): invalid pointer) but VM driver env probe OK (#8559) — link script does not refresh sidecar stamp on that path.
Done when
-
php script/check-selfhost-spine-sidecar-sync.phpexits 0 -
make bootstrap-loop-probeM2 lib spine smoke passes (or documents expected gen-0 sidecar byte-match path) - Spine link refreshes sidecar stamp when VM driver execute probe OK even if main() bundle stdout fails
