Q.LOG is v3's q48_log_approx: x = 2^k * m with 1.0 <= m < 2.0, ln m by up to 6 Newton rounds on e^y = m, result y + k * ln 2. As ruled, e^y is Q.EXP's Taylor loop written in line rather than a call to Q.EXP, so Q.LOG calls only Q.*, Q./ and UM*. After the reduction m, y, the Taylor term and its sum each fit one cell, so the 7-cell variable (QL) holds single cells. x <= 0 returns 0 and sets NODE-ERROR (D-12). Checked bit for bit against v3's q48_log_approx (ported into the test) on 22 positive edge values, 2000 pseudo-random x of every magnitude and a sweep of every 17th reduced m, at 32- and 64-bit cells, optimised and ASan+UBSan (`make test`, `make sanitize`). Mutating the round count, the 100-ulp stop, ln 2 or the Taylor length all fail. v3's clamp y = max(y - corr, 0) is kept but cannot fire: a scan of all 65536 values of m in C never reaches it, and never needs more than 4 rounds. So no test covers it. The test harness's per-call step limit is raised from 100000 to 4000000 instruction words: a 64-bit Q./ takes about 6500, and a mutant forcing extra Newton rounds ran past the old limit and looked like a width difference. Headroom (data under arg / return): Q.LOG 3/2. Test results on the amd64 host only. This is a development check, not acceptance (JUSTIFICATION.md section 16).

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material, and an archive of superseded docs.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.
