The Measurement Trinity Frame
MS-08.6Era: mirror-springTech tier: 4
Archivist note on how charter law treats storm glass, miniature orreries, and binding sigils as one accountable instrument—not three rival proofs.
Scope
After the Glass Consensus Symposium, harbor clerks and Syndicate auditors adopted a measurement trinity: three modalities must agree before a contested cargo, deposition, or tariff dispute clears review. Storm glass voices ambient ley weather; clockwork orreries audit probability drift in testimony and machinery logs; binding sigils preserve contractual pulse against retroactive edits.
This frame is not theology. It is a procedural lattice—each modality jealous of the others, yet useless alone when stakes involve smuggling, mirrored beasts, or braids that remember storms sideways.
Practice
Where two instruments align and the third falters, reviewers file a split verdict and freeze movement until a sealed laboratory duplicate reproduces the anomaly. Where all three diverge, the matter escalates under charter precedent established at Veilspire rather than by guild rumor.
Readers tracing incidents across eras should treat apparent contradictions as instrument shading, not narrative error—unless the split persists after reproduction.
