nx_jsbalance.nx -- DOES THE EMITTED JAVASCRIPT EVEN LEX? A structural balance check over a page this estate GENERATES, so a bad emit cannot reach a browser as a black screen. WHY THIS EXISTS, AND IT IS MY OWN OUTAGE. 2026-08-25 I edited nx_game_page_emit's emitted guard, shipped it through build -> promote -> ship lane -> live docroot, and /world/beach and /world/craft both went BLACK. Every gate in the chain was GREEN: the organ compiled, the wasm-vm gate passed, the ship lane read the page back and verified its marker. NOT ONE OF THEM PARSES THE JAVASCRIPT. The estate emits ~410 KB of JS per page and had no check that it lexes at all, so a single stray brace or unterminated string takes the whole script down -- and with the script down, even the software-renderer fallback never runs. That is the difference between "ugly" and "black". ★A PIPELINE THAT VERIFIES EVERY STAGE EXCEPT THE ARTIFACT'S OWN LANGUAGE IS GREEN ALL THE WAY TO THE OUTAGE. WHAT IT CHECKS, AND ONLY THIS: the three faults that take a whole script out at once -- 1. an unterminated string or template literal at EOF 2. an unterminated block comment at EOF 3. bracket depth that ends non-zero, or ever goes NEGATIVE (a close before its open) It is a LEXER, not a parser. It cannot see a misspelled identifier or a wrong argument, and it does not pretend to: those fail one call, not the whole file, and the browser reports them. ⚠ DECLARED IMPRECISION, because a checker whose blind spots are unstated gets trusted as exact. JavaScript cannot be lexed without parsing: `/` is division or the start of a regex literal depending on the grammatical position before it, and no scanner settles that without a parser. This one treats every `/` as division, so a REGEX LITERAL containing a quote or a brace would be miscounted. That is the one construct it can be wrong about, and it errs by REPORTING IMBALANCE on a valid file -- loud, never silent. Before wiring, it is calibrated on the known-good live page: if it cannot pass a page a browser runs, it is too naive to gate with, and the calibration says so rather than the ratchet being loosened to fit. license_tier: ORIGINAL No hw writes (Rule 26).
