-# Regression harness for #856: worker git-worktrees under a fresh `git worktree
-# add` have no node_modules until `pnpm install` runs (pnpm workspaces do NOT
-# share node_modules across worktrees). Before the fix, the gate-entry seam
-# (qa-hook-stdin.sh, registered as the PostToolUse hook for every Edit/Write/
-# MultiEdit in runtime/claude/settings.json) silently let a raw
-# `sh: 1: <tool>: not found` surface from any downstream gate invocation —
-# indistinguishable from a real test/lint failure (false-red).
-#
-# Asserts:
-#   1. RED (documented): a completely fresh worktree with no node_modules/.bin
-#      at all produces the raw "not found" for a gate binary — this is the
-#      defect the fix prevents from reaching the operator un-annotated.
-#   2. With node_modules/.bin missing entirely, the seam exits nonzero with
-#      the legible sentinel "deps not installed — run pnpm install" instead
-#      of silently proceeding (exit 0) into a would-be raw not-found.
-#   3. With node_modules/.bin present but empty, same legible-sentinel
-#      behavior (covers `git worktree add` immediately followed by an
-#      as-yet-incomplete/interrupted install).
-#   4. Once node_modules/.bin is populated (post `pnpm install`), the seam
-#      proceeds normally (exit 0) — the preflight does not false-positive.
-#   5. Non-JS/TS files are unaffected (existing skip behavior preserved).
