 3. Consider adding `--force` flag to binstall to ensure fresh install to correct location
 4. Add `which cargo-tarpaulin` and `echo $PATH` debug steps to CI workflow

+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+## Fix
+
+Added `--force` flag to `cargo binstall` in `.github/workflows/test.yml` so tarpaulin is always installed to `~/.cargo/bin/` regardless of stale metadata.
+
+## Root Cause
+
+`~/.cargo/.crates.toml` on the Mac Mini runner had metadata from a previous `cargo install cargo-tarpaulin` (installed via mise to `~/.local/share/mise/shims/`). Binstall found the metadata, reported "already installed", and skipped — but the binary wasn't in `~/.cargo/bin/` where `cargo tarpaulin` looks.
+
+## Verification
+
+- Force-installed tarpaulin on Mini via SSH, confirmed binary at `~/.cargo/bin/cargo-tarpaulin`
+- CI run [23319951069] passed all 4 jobs end-to-end (Build & Rust Tests, Playwright E2E, Vitest, Lint)
