The next big milestone after the three-board bare-metal cut (v2.5.0) is transferring the battle-tested amd64/aarch64/riscv64 story to a Zynq (AMD Xilinx) FPGA SoC — configurable silicon with soft/hard CPU cores, PL fabric, and a non-standard memory map, a genuinely larger step than any prior board (expected on a new even-major line). Between v2.5.0 and the Zynq sits a "coloring in" period: hardening that thickens the shape of what exists rather than adding silicon (USB BOT/xHCI + block robustness, live-entropy and Zuse-cert hardening on real ASICs, SMP/multi-core + IRQ routing from the HAL notes, driver breadth) so the FPGA carries a production-honest shape forward. Authoritative form in ROADMAP.md "Beyond v2.5.0"; FABRIC-3.md tracks the same horizon in the post-release section and re-points G.6's Next at the v2.2.0/v2.4.0/v2.5.0 cadence.
capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
| 4000+ | user-defined (ACL.4th, zuse.4th, …) |
Each block is limited to 1024 bytes. Verify with wc -c before committing.
