#!/usr/bin/env bash
# scripts/run-all-tests.sh — master local entrypoint that exercises every
# check the repo owns. CI (.github/workflows/ci.yml) does NOT invoke this
# script; it re-lists the same stages as discrete steps so failures are
# attributable per-step. Keep the two in sync when adding a stage.
#
# Stages (each fails fast):
#   1. C++ build + ctest  → scripts/build-cpp-tests.sh
#   2. WASM build          → scripts/build-wasm.sh
#   3. Parity check        → scripts/parity-check.sh
#   4. Lint                → scripts/lint-cpp.sh
#   5. Manifold tests      → codegen golden + curve drift, then
#                            cd manifold && typecheck + build + bun test + playwright
#   6. Engine bench SMOKE   → scripts/bench-engines.sh --smoke --native-only
#
# Stage 6 is REPORTING ONLY and deliberately tiny (~0.15 s, native only, no
# emcc). It exists so the benchmark cannot rot unnoticed the way an unbuilt
# firmware variant did, and so every full local run leaves a rough throughput
# table in the log. It does NOT gate: a smoke-sized run has a ±30% noise floor
# and a wall-clock threshold on shared hardware is either meaningless or flaky
# (same reasoning as the firmware flash/RAM CI job). For numbers you can
# actually compare, run scripts/bench-engines.sh on its own — it defaults to
# best-of-3 × 150 ms per engine on both targets and takes --compare.
#
# Flags via env:
#   NISPS_SKIP_PLAYWRIGHT=1   skip the Playwright leg (useful in C++-only loops)
#   NISPS_SKIP_WASM=1         skip WASM build + parity (no emcc available)
#   NISPS_SKIP_BENCH=1        skip the engine-bench smoke report
#   NISPS_LINT_STRICT=1       treat lint warnings as failures
#   PLAYWRIGHT_BROWSERS_PATH  respected (on the VPS point it at the snap-bun
#                             browser cache — see docs/specs/plans/BUILD-PLAN.md)
#
# Exit codes: 0 on full success, otherwise the failing stage's exit code.
