Reverts the interpreter-anchor halves of #95131 and #95478 (the anchor
module, its doctor check, and the update-time refresh). On real Macs the
anchored real-file copy of the uv interpreter dies in dyld: its LC_RPATH
(@executable_path/../lib) resolves into venv/lib/, which holds no
libpython — bricking EVERY hermes command including update and doctor
(#95425), and the re-pointed python3 aliases lost the stdlib
(ModuleNotFoundError: encodings, #95541). Linux CI could not catch this:
the fixture interpreters were one-byte fakes with no dynamic linking.
Kept: managed_uv._macos_sign_managed_python (#82529, @notkisk) — the
identifier-DR signing of repair generations is independent of the anchor
and unaffected by the dyld issue (it signs binaries IN PLACE in their
store, where their rpath is valid).
Added: doctor's check_macos_tcc_anchor_removed() heals venvs the anchor
already converted — restores bin/python to a symlink at the recorded
source (the anchor's own marker file) and re-points aliases; prints the
manual one-liner if the heal itself fails. Users whose CLI is fully
bricked can run the workaround from #95425 directly.
Re-land criteria: a dylib-complete anchor design (bundle libpython or
rewrite LC_RPATH), verified on macOS hardware BEFORE merge. Credit to
@kim-miram (#95358), @kokhlo (#95476), @zengzheqing (#95551) for the
forward-fix diagnoses that mapped the failure, and to the #95425/#95541
reporters.
