verify-dependency-exists

v0.0.4

Block hallucinated or unknown dependencies before they enter the repo. Watches requirements.txt, pyproject.toml, package.json, and go.mod, and blocks any newly added dependency not present in the allowlist file. Opt-in: disabled by default because it requires a curated allowlist. Enable with `chock enable verify-dependency-exists` after populating .chock/dependency-allowlist.txt. Runs at commit and at agent tool-use (a manifest edit is judged against the file on disk, and at the turn's end against HEAD). [Session-enforced via PreToolUse and Stop hooks; needs git and a Python 3.11+. PreToolUse judges the file a tool call would write; Stop re-reads what the turn actually left on disk, so a file written through a shell heredoc is judged too. With no working Python the hook exits 2; without git, fail-open clients allow silently. A gate that cannot reach a decision refuses rather than allowing one it never judged. Enforcement at every commit and in CI still needs chock installed in the repo.]
