Status
Honeycomb is not silicon yet. The current artifact is a proof-and-RTL repository: executable Lean semantics, checked theorems, generated SystemVerilog, golden simulations, analytical models, and recorded sky130 physical-design runs.
At a glance
The strongest current physical result is honeycomb_cell_mac: a generated, macro-backed cell with powered SRAM macros that reaches detailed routing with 0 DRC violations and timing met across all nine corners at a 29 ns clock.
The most important modeling result is the memory boundary. Binding the hot memories as SRAM macros cuts mapped flip-flops from 40,994 to 802, replacing a proof/simulation memory shape with something physically plausible.

Not yet claimed
Honeycomb does not yet claim fabricated hardware, signoff-clean GDS, measured power, measured silicon performance, parser-level SystemVerilog refinement, a full-chip mesh, or self-hosted software. Those are target work, not completed evidence.
