running on WebGPU at ~90ms/image, scoring 91.3% / 87.3% / 84.6% balanced accuracy (clean / web / hard degradation) at the 65% threshold on a 36,000 image held-out benchmark.

Built from the repo on a Raspberry Pi 3B+: 3D-printed optics (repo prints plus my own dome, cradle and cartridge trays for the optical head), AS7341 spectrometer, 650 nm laser + Pi camera for speckle, white + IR LEDs, ST7789 screen, 4 GPIO buttons, ATECC608B secure element with config and data zones locked, seed wrapped by the chip, PIN attempts counted on silicon. Air-gapped: request comes in as a paper QR through a scanner, the signed tx leaves as a QR on the screen, read by an iPad companion page and relayed to my own node.

BLOOD-AUTHORISED SIGNATURE, MAINNET (2026-09-08): a fresh fingertip drop passed all 6 gates live (G1 0.32, G2 2.33, G3 0.68, G4 0.90 shape / 0.78 green, G5 0.61, G6 settled 0.39 / fall 0.24 / trend -1.00). The chip signed nonce 4. tx 0x701a15dba34d598ee329cb19ba0549fe64ed9230bfb7d065cd87e18272ca3974 block 25931095, 0.00042069 ETH, 0x7a08034C1ADe7Ac7f4c1a2900b97699a05C88CB2 -> atg.eth Five pokes total: 1 and 2 rejected (drop smaller than the sensor field), 3 and 4 were real clots refused by the stock G6 terms, 5 accepted.

PULSE TIER: NOT DONE, so this is a partial claim. In the dome the AS7341 sits 16 mm from the finger and PPG through it is noise (5 of 7 touch gates pass on noise, no real beat). A MAX30102 module is ordered to stand in as the TouchSensor; pulse clip to follow.

WHAT I HAD TO CHANGE

• se_atecc.py / provision.py: provisioning must run with the data zone still open (added provisioning=True), and an unwritten baseline slot (0xFFFFFFFF) has to count as 0 or every unlock fails forever after lock-data. Working order: write secrets -> lock-data -> provision.
• Optics: the dome bore gives a ~10.7 mm field at the tray; a fingertip drop covers 30 to 65 % of it, so every colour ratio scales with drop size. Added a 2.5 mm aperture insert. Stop 1 white reference = blank tray fully in (2.9 % spread across trays).
• Thresholds retuned (thresholds_poke3.json), G4 gained a green-index path, G6 rewritten (rank to the floor, fall >= 0.03, settled <= 0.80). Every fake on disk (blank, milk, ketchup, glue, glue+dye) still rejects on 2 or more gates.
• Clotting: on this well "arrested <= 0.25 in 600 s" never happens for a fingertip drop. It plateaus around 0.4 to 0.6 and keeps falling for 30+ min.
• AS7341 driver: the adafruit SMUX-enable wait spins forever after a bus glitch. Added a timeout and a one-call read. One process on the I2C bus at a time.
• read_bore_reference integrates at 281 ms while read_ppg samples at 2.8 ms, so T1 (fraction of bore) is ~100x off as shipped.
• The signed QR is shown ~1 s in the repo; hold it until a button press. Also atg.eth is EIP-7702 delegated, so 21000 gas reverts; use eth_estimateGas. Captures (.json), thresholds and patches available; I will open an issue on the repo with the numbers.

had a great time making them :)

claiming this, then manually splitting the funds 50/50 between Kafani and Hanma for their excellent claims

"It was a galleries full of happiness of mine"

These two pictures, I felt it was really something wholesome moment, It was during typhoons striked in our country. I find these two picture wholesome because despite facing our own difficulties due to typhoons, we still able to help others and seeing the smile of my fellow filipinos while they received there relief goods- was priceless. It was quite tiring, but seeing their priceless reaction really fulfilled my heart.

It brightened my day to saw filipinos helping each other despite with the calamities we ever facing. This day, I can say that it was a challenging one but really full of lessons.

"The strongest people make time to help others, even if they're struggling with their own personal problems." - this quote is indeed the quote of the day. No matter your problems you're facing now, if you can help others, then DO IT.

These two pictures, captured not just only happiness, but also courage, and compassion Thanks for @ruxxx @kenny @jesse.base.eth for another fabulous poidh bounty where, I can shared these two photos that held deeper meaning and lessons!
