Signed

Lock	Value
geometry & material labels	Wheel 48.00 OD, 13 blades, 19 vanes, Haynes 282. 80k / 25 MPa / 650 C are LATER-stage labels. First spin is catcher-only under 20k.
soak gap & gap eat	Soak gap 0.20 cold / 0.18 hot. Gap eat 0.0148 mm (ccx cent-only) holds vs Stage 0.019. Soak rim ur 0.226 is free-rotor thermal (0.211) + cent, stator matches, NOT a rub.
CoolProp mean-line state points	CoolProp HEOS Span-Wagner: inlet 25 MPa / 650 C → dump 13.89 MPa / 579 C, C 30→208→40, Δh0 75.9 kJ/kg, η_tt 0.802 / η_ts 0.746. 0.75 stays a label. PR 1.8. U2 201 m/s. α2 75°. M2 0.43.
loss register	Loss pts of Δhs: incidence 1 / passage 8 / TE 2.5 / tip Japikse 4.8 / windage 1.
ROSS map	ROSS 2.3 undamped: foil 1e6–5e6 crosses a critical before 80k. First pair 26.4k at 1e6. Need k ≳ 5e7 for 80k. J2 foil can ends Z=71.00, disk 72–76.
FEA stress numbers	CalculiX 2.23: rim VM 246 MPa, global VM 307 MPa vs sheet Sy 631 MPa at 649 C. AM Sy unsigned.
STEP freeze	STEP frozen. B3DO keeps cad/rig/cooky_t1_foil_rig.step. C3DO does not cut. No AMB geometry. Quote STEP stays Z=72 / 0.55 and is NOT this site's article.

Item	Why it is not signed
η_ts 0.75	stays a label.
η_tt 0.80 / η_ts 0.75	labeled, not signed.
80k / 25 MPa / 650 C	later-stage labels; first spin is catcher-only under 20k.
Exit swirl C3 = 120 m/s	labeled, NOT signed.
AM Sy	unsigned until a Z-build 650 C Sy cert (step 4).
TC 0.20	still not trip-safe (step 3).
