Measured Drift of Stone

0.72 MPa — fault scissor-tested; mica sheets whisper a calm delamination.

12.6 mm — basalt vein offset; sediment layers keep their patient inventory.

0.004°C/day — fossil matrix creep, recorded like a misfiled sigh.

(the instruments grin; the record admits a soft error)

Seam residue: quartz dust along the groove; keep the hand.
