The compaction re-injection hook previously required users to hand-merge
an example into user-level ~/.codex/hooks.json — which renders in the
Codex hooks UI as an anonymous, unattributed "Hook 1" and puts the
install burden on every user. Restore the plugin-provided delivery this
repo used before "Remove Codex hooks" (640ce6c0): the Codex manifest
points hooks at hooks/hooks-codex.json, which runs session-start-codex
via ${PLUGIN_ROOT}/hooks/run-hook.cmd with matcher "compact".
Unlike the removed hook, this one never fires at session start — Codex
surfaces skills natively there, which is why the old startup-injecting
hook was removed. The matcher plus the script's own source gate restrict
it to post-compaction re-starts. The explicit manifest pointer also
keeps suppressing Codex's hooks/hooks.json auto-discovery fallback,
which the previous empty-object declaration existed for (7d8d3d4b).
The Codex portal archive now ships hooks/hooks-codex.json,
hooks/run-hook.cmd, and hooks/session-start-codex; other-harness hook
files stay excluded.

The packaging pipeline only worked on a Mac with default umask, for
three stacked reasons:
- The deterministic-metadata tar flags (--uid/--gid/--uname/--gname)
are bsdtar spellings; GNU tar rejects them, so the tar.gz archive
step died on Linux. Detect the tar flavor and use --owner=:0
--group=:0 --numeric-owner on GNU tar, which writes byte-identical
ustar headers (uid/gid 0, empty uname/gname).
- Staged file modes depended on two umasks canceling out: git archive
masks entry modes with tar.umask (git default 0002 -> 775), and the
unflagged tar extraction re-masked with the process umask (022 on
macOS -> 755, but 002 elsewhere -> 775). Pin tar.umask=0022 on the
archive call and extract with -p so staged modes are canonical
755/644 on every machine.
- The test's timestamp assertion parsed bsdtar's -tv column layout and
expected epoch 0 rendered in a US timezone ("Dec 31 1969"); GNU tar
uses different columns and UTC hosts render "1970-01-01". Assert
mtime == 0 via python3 tarfile instead, matching how the test
already checks zip timestamps.
tests/codex/test-package-codex-plugin.sh now passes on Linux/GNU tar;
the bsdtar branch preserves the exact flags that passed on macOS.
