about

nx_js_regex_features_gate.nx -- regex-engine features added during the Octane RegExp arc (2026-07-12), V8-pinned on BOTH tiers. Locks in: lookahead (?=)/(?!), backreferences \1..\9, \xNN pattern escapes, AND the catastrophic-empty-loop SAFETY fix (`/^(a*)*$/` used to SEGV the native stack -> now bounded, per the engine's never-crash contract) + iterative single-atom loops (RE_LOOPA). Each value is exec-capture-length summed (Exec) or a boolean, checked against node/V8. expect_exit: 0 license_tier: ORIGINAL
