Integrate RNG, CRC, WS2812, Crypto, I2S master and the SDIO private AXI owner on SAFE24. Preserve the 128 KiB main SRAM and six private Crypto macros, add product-specific DMA assignments and reject unsupported SDK operations.
Correct APB read strobes, I2S receive assembly and SDIO command timing, backpressure and descriptor retirement. Add pin-level workloads, source-bound evidence checks and publication/commercial consumer compatibility.
Validation of the final P6 worktree: 1726 pytest tests passed with one optional pypdf skip (exit 0, 4021.61 seconds; terminal session 36439). Both PDKs passed both RTL simulators, netlist boot and 38-macro binding checks. Shared formal, Mini compatibility and software/source quality gates passed.
Evidence remains attributed to the retained dirty-worktree snapshots based on b3b30a72cd under build/ics55-tiny-2026-10-12-11-50-2eb98c0e1fae/meta/tiny-r2-p6/. Timing is negative and warning observations are not promoted. This commit does not accept P6, qualify physical operation or enable P7.
