PR #245 fixed the trailing-keyword shape for runner heads via classifyRunnerHead (npm/pnpm/yarn/cargo/go/npx/pnpx synthesize a canonical of just `head subcommand` before matchFamilyRegex). The structurally same-class hole remained for the rest of STRICT_GATE_HEAD_ALLOWLIST — heads whose binary name IS the family signal (tsc/eslint/vitest/jest/mocha/ruff/ mypy/playwright/cypress/wdio). Their fallback ran matchFamilyRegex against the whole canonical, so a trailing HARD3 keyword promoted the entry: classifyGateCommand('tsc playwright') → 'hard3_resilience' (wrong) classifyGateCommand('vitest playwright') → 'hard3_resilience' (wrong) ANSI-C `$'...'`, parameter expansion `${...}`, and locale translation `$"..."` wrapped arbitrary text into the same forgery surface: classifyGateCommand("tsc $'playwright'") → 'hard3_resilience' (wrong) classifyGateCommand('tsc ${FOO}playwright') → 'hard3_resilience' (wrong) Fix: extend the synthesized-canonical pattern to non-runner heads. After classifyRunnerHead returns undefined, if the head is a head-as-signal binary, run matchFamilyRegex on just the head — trailing positional args and quote/expansion wrappers never reach the keyword scan. Both shapes close in the same change because the post-head text is dropped entirely. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
