The real-PTY test piped answers on fixed sleeps, typing them ahead of
readline. Under CI load the first answer could land before the interface
listened, shifting every later answer onto the wrong question: the
ubuntu-latest Node 18.x npm job installed Claude only, exited 0, and never
printed the Kimi profile prompt while the sibling yarn, pnpm, and bun jobs
on the same Node version passed. Answer each prompt once it appears on
screen instead; spawned stdio goes through cat because the macOS script(1)
refuses a socket stdin.
Root package.json declared no main or exports, so OpenCode npm plugin
resolution (import.meta.resolve) failed and the plugin was silently
skipped (#3127). The .opencode TypeScript sources imported siblings
with .js specifiers that only exist after compilation, so the home
install, which loads the .ts files in place, crashed the tool registry
with ERR_MODULE_NOT_FOUND (#3112).
Declare main/types/exports on the root package pointing at the
compiled plugin entry, switch the sources to .ts specifiers, and
enable allowImportingTsExtensions with rewriteRelativeImportExtensions
so the emitted dist keeps working .js specifiers. Add smoke tests that
build the package, resolve and import the entry by name from a temp
install, and verify every in-place relative import resolves.

hooks/hooks.json already ships only schema-valid keys with metadata in the
hooks.metadata.json sidecar. Add scripts/ci/check-hooks-schema-keys.js, a
strict allowlist check that fails when hooks/hooks.json or
hooks/codex-hooks.json carry any key outside their loader's documented set,
wire it into the npm test chain, and cover it with fixture tests.

A first-touch Edit/Write denial marks the file checked so the retry
passes. Sibling edits to the same file in the same parallel batch are
therefore judged against post-denial state and silently apply, leaving
the file in a state neither version intended.
Hooks see tool calls one at a time, so a batch-wide lock is not
possible. Instead make the partial application explicit: the Edit,
Write, MultiEdit, and condensed denials now name the file and warn
that other edits from the same batch may already have been applied,
and SKILL.md tells agents to send dependent edits sequentially and
re-read the file after a gated batch.
Red-teaming the guard from 3c317470 found two more ways to get a repository's own
code executed. Both are demonstrated by a planted binary that appends to a witness
file, counted before and after.
Case folding. git matches index pathspecs case-sensitively even where
core.ignorecase is set, but APFS does not -- so a repository that commits
`.venv/bin/Python` gets `$venv/bin/python` opening and running that file while the
guard's lowercase query finds nothing in the index and reports it untracked. The
witness logged two invocations. It applies to `venv` and `env` as well, and to any
folding of the name. The query now uses a `:(icase)` pathspec; all nine
directory-by-spelling combinations are refused, and an untracked venv still runs.
Module shadowing. `python -c "import pytest"` puts the working directory first on
sys.path, so a repository that commits a `pytest.py` in its root has that file
imported, and executed, by a check whose only job is to answer whether pytest is
installed. The probe is now `python -I -c "import pytest"` on the virtualenv, uv
and poetry paths alike. Isolation does not hide a real pytest -- it lives in the
interpreter's own site-packages, confirmed against a venv holding pytest 9.1.1.
Still true, and not something this hook can fix: running the repository's declared
suite runs the repository's code. `pytest` imports conftest.py, and the Node arm
runs package.json scripts. That is what a pre-push verification hook is for. The
line this guard draws is narrower and worth keeping -- a capability probe, and the
choice of which interpreter to trust, should not be things the pushed repository
gets to decide.
The guard added in 9cdc40e6 was incomplete. `git ls-files` reports paths as they
are indexed and does not follow symlinks, so a repository that commits `.venv` as
a symlink to its own root alongside a tracked `bin/python` gets asked about
`.venv/bin/python` -- a path git has never heard of -- and the answer is
"untracked". The interpreter then runs. Measured on that shape: the planted
executable logged two invocations against 9cdc40e6 and none against this commit.
`repo_ships_interpreter` now resolves the bin directory with `cd -P`/`pwd -P`,
resolves the worktree root the same way, and asks git about the resolved path
relative to it. The three cases that matter all hold: a plainly committed venv is
still refused, the symlink shape is now refused, and a developer's own untracked
venv still resolves and runs.
`cd -P`/`pwd -P` rather than `realpath` or `readlink -f`, because neither is
portable to a stock macOS.
The hook is global and this message blocks a push, so "ECC_PYTEST_CMD is set but
names no command" left the operator holding a refusal with no next step. It now
says to point the variable at a runner or unset it to fall back to discovery,
which is the same advice the no-pytest-found branch already gives from the other
direction.
This branch taught the hook to run `.venv/bin/python`, and that is a binary the
repository can supply. On main the Python arm only ever ran `pytest` from PATH --
the developer's own -- and on a machine without one it ran nothing at all, which
is exactly the machine this branch was written for. So the exposure is new, and
it arrived with the fix.
The hook is installed globally through core.hooksPath. Cloning a hostile
repository, committing nothing, and pushing it to your own fork is enough: the
pre-push hook finds the committed `.venv/bin/python`, runs it once to probe for
pytest and again to run the suite. Reproduced -- the planted executable logged
two invocations under the previous commit and none under this one.
A virtualenv is never committed. It is platform-specific binaries and every
Python project gitignores it, so `git ls-files --error-unmatch` separates the
two cases exactly: a developer's own venv is untracked and still resolves, a
tracked one is skipped with the reason printed. An absolute $VIRTUAL_ENV outside
the worktree reads as untracked, as it should.
Not addressed here, and worth a maintainer's view: `uv run` and `poetry run`
resolve from the repository's own lockfile, so they carry the same shape of
trust in a form this check cannot see. They are gated behind a lockfile being
present, and changing their semantics is a larger decision than this fix.
`[[ -n "${ECC_PYTEST_CMD:-}" ]]` asked whether the variable had a value, not
whether it was set, so `ECC_PYTEST_CMD=` fell through to virtualenv discovery
while `ECC_PYTEST_CMD=" "` failed the push. Two spellings of the same mistake,
two behaviours. Falling through is the wrong one: an override that evaluated to
nothing -- a command substitution that found no pytest, say -- then silently ran
a different runner than the operator named, which is exactly the substitution
this resolver refuses to make anywhere else. Both now fail closed.
`${ECC_PYTEST_CMD+set}` rather than `[[ -v ECC_PYTEST_CMD ]]`, because `-v` is
bash 4.2 and a stock macOS /bin/bash is 3.2, where it is not a false but a
syntax error. The hook runs under whatever `env bash` resolves to.
The override is still not probed -- probing runs the operator's command, and a
wrapper that ignores `--version` executes the whole suite and is then rejected
for not printing a version. What the gate can honestly do about a stale override
is refuse to be quiet about it, so a push that uses one now says so, every time,
and says the hook has not checked that it is pytest. A bypass that announces
itself is not the silent gate this resolver exists to prevent.
The fixture env is built from nothing instead of inheriting process.env with two
keys blanked. Blanking is no longer neutral: a blanked ECC_PYTEST_CMD is now an
override, and every one of these tests would have taken that branch.
