WHAT WE BUILT • OCTB (Optical Compatibility Test Bench) — try a camera/lens/light swap in software before buying hardware, and prove the instrument still gives the same answer. • It simulates how the new hardware forms the image, runs the ORIGINAL legacy analysis algorithm unchanged, and checks the decision is preserved (same grade, successful decode, metric in tolerance). • Every value is provenance-tagged; the legacy grader is byte-frozen and hash-verified so its verdict can't drift. WHAT WE FOUND • A hardware swap can SILENTLY change the answer — the failure is invisible until after you've bought the part and re-run real assays. • Example the app makes obvious: a Red-630nm light turns every color patch red and wrecks the grader — caught before a cent is spent. WHY IT MATTERS • Legacy machines from the 1990s–2000s still work and produce value, but their specific camera/lens/lamp goes end-of-life. • You can't just drop in a replacement (software was tuned to the old optics), and ripping out the system means costly re-engineering + revalidation. • Today qualifying a part means buy → install → run assays → compare → repeat: weeks per candidate on a validated instrument. • OCTB does the first pass in software: screens the whole market, ranks the few parts worth physically testing, and builds the evidence report — without touching the trusted legacy system.
