Samsung SF2P stub — backup 2028 target (BLOCKED)

Fail-closed evidence file for Samsung SF2P (3rd-gen MBCFET GAA, frontside). SF2P is documented as a backup 2028 target if both TSMC (N2P / A14) and Intel (14A) paths are blocked.

Samsung SF3 yield issues limited external uptake; SF1.4 slipped to 2028-2029. For external customers, Samsung SF2P is realistic but less proven than TSMC at the equivalent node. SF2Z (BSPDN) arrives 2027 and is a separate gate.

No SF2P PDK data, library, GDS, LEF, extraction view, SRAM macro, PHY hard-IP, or signoff report is or will be checked in until a Samsung Foundry SAFE program or NDA agreement is in place.
