Credibility pass: the code reads as one hand's work. Dead plumbing and copies removed, four claims the source does not support corrected, and inherited kit text re-read for this game

Engine: the facade re-exports the board in one block; describe() and the
dead letters preference, void ply, the King-taken line, the identity maps
and the unused imports are gone; SIDE_NAMES is the one spelling of a side;
the drake's hunter comment no longer claims only four kinds reach the air.
Prose: no shatranj and no sitting duck, which Gygax never wrote; the Thief
statistic and the Basilisk's "one trick" are gone; lessons say what the
board shows instead of repeating the panel; a Thief's leap counts four.
Browser: one keyboard walk, in BoardArtwork; the lesson board and page share
one game and one inspected piece; the chronicle's possessive is told, not
patched by a regex; the chronicle colours and the reading layout are global
rules instead of three copies; the guide and the about panel say what the
code and the article actually do.
Server and docs: the room server states that it is the kit's, kept whole;
the skills, the deploy README and the share card name files that exist.
