    "identityLock": "The Hall of White is one exact institutional room inside Cinderwall: an octagonal chamber with polished Yumiko-Prism walls, floor, and ceiling; eight clerestory windows keyed to four canonical hours; one central practice circle; twelve Aspirant seats, three senior-Prism seats, and one slightly raised White seat. Prism stone dampens voices, and wear, measurement, risk, and reserved authority must prevent whiteness from reading as empty luxury.",

  "storyBeat": "At the Hour-of-the-Quiet, the sixteen-seat order is visible around an empty central circle; a seven-band Yumiko-Prism lens rests on its worn inscription, the eastern wall carries one faint unresolved glow, and measured absence makes institutional consequence legible without depicting an unapproved character identity.",
