Authorized R4 D exact SHT source repair
Existing SHT40-AD1B-R2/C2909890 has erroneous EP terminal5 and physical pad. Inspect source permissions; if read-only create/import corrected exact source, not a differently named variant. Verified USER map ONLY four terminals1SDA bidirectional,2SCL input,3VDD power in,4VSS Ground, no EP. Actual required footprint Sensirion_DFN-4_1.5x1.5mm_P0.8mm_SHT4x_NoCentralPad at https://gitlab.com/kicad/libraries/kicad-footprints/-/raw/master/Sensor_Humidity.pretty/Sensirion_DFN-4_1.5x1.5mm_P0.8mm_SHT4x_NoCentralPad.kicad_mod ; retrieve before use, no guessing. Remove fictitious EP terminal/copper/mask/paste via actual four-land asset. Preserve exact MPN/manufacturer. Publish corrected source before adoption; report UID/version/full URL and readback four terminals/four distinct pads/no central copper or stencil. Missing3D disclose separately, does not block verified copper/electrical fix. No carrier edits. One bounded attempt if unsupported return concrete blocker. Write source correction evidence file.

I’ll check source access, retrieve the specified four-land footprint, and create a corrected exact-MPN source if the existing library part is read-only. I’ll verify its terminals and copper before reporting a published version; no carrier edits.

flux

Blocked: the existing source is read-only, and the exact-MPN symbol-file creation attempt was rejected, so no corrected UID or version was published. I confirmed the fictitious EP terminal and central copper/mask/paste pad, retrieved the required four-land asset, and filed a part-quality report; no carrier edits were made.
Evidence and the concrete continuation requirement are recorded in sht40-source-correction-evidence.
