Adds the design/scope doc and the first runnable milestone (M0) for driving BL-1's closed-loop experiments against live FinalSpark organoids, reusing the existing encode/decode/game/feedback machinery with the simulator as a dry-run digital twin. - docs/design/finalspark_integration.md: architecture (NeuralBackend Protocol unifying SimBackend + FinalSparkBackend on a rate-coded tick), the three hard constraints (10 s stim re-upload -> <=16 trigger bank; ~1 Hz polling loop; count-based decoding + charge-balancing safety), digital-twin strategy, single-organoid-first decision, milestones M0-M4, and risks. - experiments/finalspark_smoke.py: read-only M0 — connect via Experiment(token), list electrodes, pull recent spike counts/events from the Spike DB, save raster + per-electrode-count plots. Token via FINALSPARK_TOKEN env var; runs inside FinalSpark's environment. - pyproject: optional [finalspark] extra (public np-utils helpers; core neuroplatform is environment-provided, documented inline). Experiment scripts live outside src/bl1 and tests, so lint/test/quality CI scope is unaffected (verified locally). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Scopes connecting BL-1's closed-loop machinery to live FinalSpark Neuroplatform organoids, and ships the first runnable milestone (M0).
What's here
docs/design/finalspark_integration.md— full design/scope.experiments/finalspark_smoke.py— M0, read-only & safe: connect, list electrodes, pull recent spike counts/events, save raster + per-electrode plots. Run inside FinalSpark's env withFINALSPARK_TOKEN.pyproject— optional[finalspark]extra (publicnp-utils; coreneuroplatformis environment-provided).Key design points
SimBackend(digital twin) andFinalSparkBackendare interchangeable behind aNeuralBackendProtocol.send_stimparam()is a ~10 s upload → sensory encoding pre-discretized into ≤16 triggers; ~1 Hz polling loop (Trigger.send→ 200 ms →read_count()); count-based decoding + mandatory charge balancing.CI
Experiment scripts live outside
src/bl1andtests/, so lint/test/quality scope is unaffected (verified locally: ruff + format clean onsrc/bl1).Open question for FinalSpark (blocks M1)
Max safe stimulation amplitude/current is unspecified in the docs — must be confirmed before any stimulation milestone.
Milestones M0–M4 tracked in linked issues.
