Our direction
How browser-first experiments, canonical assembly contracts, bounded authority, and verifiable receipts fit together across G0–G5.
RESEARCH & ENGINEERING NOTES
Follow the
current direction.
SeedCore focuses on an open trust runtime for physical AI, pairing the Central World component & assembly authoring stack (CW1, CW-A01 v2, CW-A02/A03) with simulation-first Microduck (M0) and Fast Spine (fast-spine-v1) rehearsal.
Robot Lab & Central World
The SIM-3 C++/Wasm 3D Tree Studio, local Central World CW-A02/A03 Mini Studio authoring and placement, and fast-spine-v1 bounded-session rehearsal.
Development notes
The SeedCore repository is the canonical source for active queues, acceptance matrices, test runners, and hardware qualification registers.

Build from the evidence.
Local source snapshot through 12aa49e (CW-A03), following 4708e06 (CW-A02). Software acceptance is separate from physical qualification.
This snapshot includes local acceptance records not yet available on the public repository. Source paths below identify those records; the public links open available summaries and published documents.
Mini Studio & Proxy Placement
Strict raw-JSON seedcore.assembly.v2 import with duplicate-key rejection, 32-entry / 2 MiB frozen revision store, undo/redo, stale-load fencing, and Three.js box-proxy preview, plus 15 mm snapping, ghost previews, numeric placement, and subtree reparenting (88 TS tests, 14 API tests, 18 browser groups).
Local source record: docs/development/robotics/central_world_cw_a02_authoring.md and docs/development/robotics/central_world_cw_a03_snapping.md.
Assembly v2 Authoring Contract
RFC 8785 seedcore.jcs-safe-integers.v1 canonical serialization, exact catalog file-byte pins, opposed_z_rx_pi mating poses, and 5-part tabletop-starter.sc-assembly.json (0.2.0, 117 Python + 71 Node tests).
Local source record: docs/development/robotics/central_world_cw_a01_acceptance_plan.md.
Bounded-Session Rehearsal
Pinned microduck-sim-v1 read-only HAL adapter, 16 upstream-derived observation/ONNX goldens, fast-spine-v1 split-screen session rehearsal, and Python/Rust simulation receipt verification.
M0 & CW-D01 Source Register
Rechecks pinned Microduck runtime/RL/model commits and records ESP32-S3-DevKitC-1-N8R8 and Feetech STS3215 (spec A/0) reference facts while keeping connector pinout and 4–7.4 V rail reconciliation open.
Local source record: docs/development/robotics/m0_cw_d01_register_2026_10_19.md.
mjswan 0.11.9 Integration
Evaluates mjswan 0.11.9 as a conditional CW-S02 / CW-S03 browser MuJoCo candidate, documenting MuJoCo 3.11.0 vs 3.15.0 and mjlab version conflicts plus required worker/veto/telemetry seams.
Central World Delivery & Gates
Defines the work-package sequence (CW-A03 proxy placement delivered locally → CW-A04 DRC next → CW-S/G/E/F/L) and the required positive/negative evidence in the acceptance matrix.
