docs/analysis/class-v6/history.md: 21 chip rows by mechanism (what each chip specialised, what the design missed, the timeline, the v6 layer, closed or not, the per-joule number); in-depth sections for Ethash (the E3's DDR3, Linzhi's 4.4 GB beside 64 compute units, the Jasminer X4's DRAM hybrid-bonded onto a 40/45 nm die, the E9), ProgPoW (the Least Authority and Rao audits read from the PDFs, Kik, Linzhi's claim, the adopters), RandomX (the X5's RISC-V board at 1.46x, the X9 announced December 2025 and withdrawn May 2026 with zero units, RandomX v2 released 25 March 2026 with activation pending, the Qubic episode as the detector's lesson), Cuckoo (the GRN1's 512 MiB SRAM die, the G32, the iPollo G1, the 2025 bounty), Equihash (the Z9's single die, the Fudan parameter-following design), Scrypt and Argon2 (the BM1485's on-die scratchpads, Percival's lookup gap, MTP), the no-chip hashes, kHeavyHash, CryptoNight, X16R, Lyra2REv2, the compute rows. The four layers against the history layer by layer, with the E3's death dates, Autolykos's growth rule, the design-cycle and FPGA-compile clocks, and the honest verdict that the stored-dataset chip (class C) is not closed by any layer: 5.1x per joule at zero premium, 2.1x with the shadow at k = 1. Two corrections to the 5 October file (the X9, RandomX v2) and one claim marked unverified (the 5x fork-surviving chip). First cut for 15:00 UK; the full report by 09:00 UK on 9 October.
