#   scripts/m7_ship_gate.sh --gates 3,6         # only gates 3 + 6

#
# Gate map (kept in sync with .pitboss/play/plan.md track M.7):
#   Gate 1: Static-only scan is green on `tests/benchmark/corpus`.
#   Gate 2: `cargo nextest run --no-fail-fast --features dynamic` is green.
#   Gate 3: With-verify / static-only wall-clock ratio ≤ 1.5× on
#           `benches/fixtures/`.  Phase 22 had relaxed this to ≤ 2×
#           while only `javac` had a warm daemon; Phase 23 lands the
#           cross-lang build pools (shared caches for Node/Python/PHP/
#           Ruby/Go/Rust/C/C++), so the bar is tightened back to ≤ 1.5×.
#   Gate 4: SARIF schema validation on every dynamic verdict variant.
#   Gate 5: Layering boundary test green.
#   Gate 6: Java OWASP Benchmark v1.2 `--verify` acceptance.  Wall-clock
#           ≤ 15 min on CI / ≤ 10 min on the dev reference machine; and,
#           per OWASP cap backed by a sound runtime oracle, confirmed-rate
#           ≥ 40%, precision ≥ 0.85, recall ≥ 0.40, plus the per-(cap,lang)
#           budget in tests/eval_corpus/budget.toml.  Added Phase 22 as the
#           headline acceptance for the warm `javac` daemon; Phase 27 (Track
#           R.0) added the precision/recall/budget ratchet.  The corpus is
#           *not* checked into the repo; the gate skips with a clear message
#           when `NYX_OWASP_CORPUS` does not point at a real checkout.
#   Gate 7: JS/TS real-corpus acceptance (Track R.1 / Phase 28).  OWASP
#           NodeGoat (Express, .js) + OWASP Juice Shop (TypeScript, .ts)
#           `--verify` against the committed ground truth.  Same shape as
#           Gate 6: wall-clock budget + the per-(cap,lang) budget in
#           tests/eval_corpus/budget.toml hard-enforced; per-cap
#           confirmed-rate / precision / recall published report-only
#           (NYX_JSTS_FLOOR_CAPS empty by default).  Each corpus row
#           self-skips unless its NYX_NODEGOAT_CORPUS / NYX_JUICESHOP_CORPUS
#           points at a real checkout.
#   Gate 8: Polyglot real-corpus acceptance (Track R.2 / Phase 29).  OWASP
#           RailsGoat (Rails, .rb), DVWA (PHP), DVPWA (aiohttp, .py), gosec
#           (Go) and the RustSec advisory-db (Rust negative control), one
#           row per corpus.  Same shape as Gate 7: wall-clock budget + the
#           per-(cap,lang) budget hard-enforced; per-cap confirmed/precision/
#           recall report-only (NYX_POLYGLOT_FLOOR_CAPS empty by default).
#           Each row self-skips unless its NYX_<NAME>_CORPUS points at a real

# nothing, while the per-(cap,lang) budget (unsupported_rate,
