rajamesandClaude Opus 5.5 93d09840da feat(v4.0.0): SM/REM and DNEGATE call-free; execute /MOD and its section 5 words
SM/REM as written in section 4 never returned correctly for a negative
dividend. It holds three entries on the return stack and then calls
DABS -> DNEGATE -> D+ -> U> -> SWAP/U<, which overflows the 9-deep
circular return stack (D-2). DABS itself could not run: DNEGATE as
written (inv SWAP inv SWAP 1 0 D+) left its caller no return entries.

- DNEGATE: inv over if L1 drop push inv 1 + pop ; L1: drop 1 + ;
  i.e. ~d + 1, carrying into the high cell exactly when lo = 0.
- SM/REM: sign tests are native -if (as in 0<) and NEGATE is in line;
  the only calls are DNEGATE and UM/MOD, both call-free inside.

Executed on the golden model at 32- and 64-bit cells, optimised and
under ASan+UBSan:
- SM/REM on dividends built as q*n + r with |r| < |n| and r signed as
  d: every edge-vector q, n with r = 0 and r = +-(|n|-1), plus 20000
  pseudo-random cases.
- /MOD, U>, ABS, S>D, D+ and DABS as written in section 5, against C
  (D+ over all 50625 edge-vector quadruples).
Mutations of DNEGATE's carry and of each SM/REM sign branch are caught.

Headroom (data cells under args / return entries under return address):
  SM/REM 5/3, /MOD 5/2, DNEGATE 7/7, DABS 7/6, ABS 8/7, U> 6/5.
D+ as written is exact but leaves only 1 return entry; recorded in
DECOMPOSITION.md 5.7 as not yet revised.

StarForth / LithosAnanke Documentation

This is the lithosananke branch: the bare-metal StarKernel side of the project (contrast master, which is the hosted-VM-only side). Documentation follows the two-tier model described in docs/CLAUDE.md: formal/ is the polished, citable LaTeX tier; working/ is living design notes and drafts that feed it. Everything else in this directory is branch- or subsystem-specific material that doesn't fit either tier.

Layout

  • formal/ — Three-volume LaTeX documentation set (research volumes, practitioner books, standalone reports) plus the scraps/ fragment library it's assembled from. Audience: patent counsel, SSRN reviewers, licensees, hobbyists with hardware in hand. See formal/CLAUDE.md for authoring conventions.
  • working/ — Living documents: architecture design notes, DoE experiment logs, hardware/platform notes, draft specs, academic-paper source material, and an archive of superseded docs. Source material for formal/.
  • 03-architecture/ — Tripod VM architecture constraints (Hera/Hermes/Artemis) and the word-level ACL system design.
  • lithosananke/ — LithosAnanke kernel branch documentation: milestone roadmap, system architecture, HAL reference, kernel command-line argument design, and the amd64 APIC-timer ISR postmortem.
  • birthing/ — VM birthing plan and status for the Hera-spawns- Hermes/Artemis constellation, plus three-architecture QEMU acceptance logs.
  • patent/ — Provisional patent application source. Legal hold — ask Bob before touching anything in this directory.
  • api/ — Generated Doxygen tag file and warnings log (gitignored; not part of the tracked doc tree).
  • pptx/ — Elevator-pitch and deep-dive slide decks for different audiences (technical, non-technical, academic, PhD-level).

Current Active Work

  • LithosAnanke M7/M7.1 — VM parity validation and init capsule architecture. See lithosananke/README.md and lithosananke/M7.1.md.
  • Word-level ACL system — Phase 6 complete on master; Phase 7 (LithosAnanke parity) is the next step. See 03-architecture/word-acl/README.md.
  • Tripod VMs — Hera (governor), Hermes (messenger), Artemis (memory/block storage). See 03-architecture/tripod/README.md and birthing/.

Contributing

  • Place new material in working/ first; promote to formal/ only when it's ready to be cited (see formal/CLAUDE.md for promotion criteria).
  • Never touch patent/, formal/patent/, formal/scraps/legal/, or working/legal/ without Bob's explicit instruction.
  • Add a README.md to any new category-level subdirectory, following the format used throughout this tree: orientation paragraph + bullet list of real files with one-line descriptions.
