DECOMPOSITION.md 5.26 described both words in prose only. They are now
written out, call-free, on one observation: +* with S = 0 never adds, so
each step is an exact arithmetic right shift of the double T:A.
: Q.FROM-INT ( n -- q ) push 0 a! 0 pop 15 FOR +* UNEXT push drop a pop ;
T:A = n:0 is n * 2^N; N-16 shifts leave n * 2^16 (count 15 at
32-bit cells, 47 at 64).
: Q.TO-INT ( q -- n ) push a! 0 pop 15 FOR +* UNEXT drop drop a ;
16 shifts at every width; the low cell is left in A. Rounds toward
minus infinity, as v3's arithmetic shift does.
Both clobber A; added to the section 2 list.
Checked at 32- and 64-bit cells, optimised and ASan+UBSan:
- Q.FROM-INT against n * 2^16 for edge values and 20000 pseudo-random n,
and against v3's q48_from_u64 for n >= 0 (low cell at 64-bit, D-10).
- Q.TO-INT against v3's (int64_t)q >> 16 on the edge Q values and 20000
pseudo-random Q values, and against a C double shift on 20000
arbitrary doubles.
- Round trip Q.TO-INT(Q.FROM-INT(n)) = n.
Mutating either shift count or the S = 0 setup fails 40000+ checks.
Note: make sanitize prints UBSan reports but does not fail on them. One
was found here, in the test's own random shift amount (fixed); a grep of
the full sanitize output now shows no runtime errors.

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. Seeformal/CLAUDE.mdfor 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material, and an archive of superseded docs.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.mdandlithosananke/M7.1.md. - Word-level ACL system — Phase 6 complete on
master; Phase 7 (LithosAnanke parity) is the next step. See03-architecture/word-acl/README.md. - Tripod VMs — Hera (governor), Hermes (messenger), Artemis (memory/block
storage). See
03-architecture/tripod/README.mdandbirthing/.
Contributing
- Place new material in
working/first; promote toformal/only when it's ready to be cited (seeformal/CLAUDE.mdfor promotion criteria). - Never touch
patent/,formal/patent/,formal/scraps/legal/, orworking/legal/without Bob's explicit instruction. - Add a
README.mdto any new category-level subdirectory, following the format used throughout this tree: orientation paragraph + bullet list of real files with one-line descriptions.
