rajamesandClaude Opus 5.5 79db0e8d88 build: v4 is the default build -- every kernel boots v4; acceptance is v4 on three ISAs and the 32-bit build 
Captain Bob, 2026-10-14: "v4 is the default build", "no, qemu to v4
too ... we are effectively trying to retire v3", "the 32 bit build needs
to go into the acceptance test too", "i don't care about v3".

- STARFORTH_V4 defaults on (Kconfig default y) and V4_DEFAULT=1
  everywhere: every kernel carries v4 and v3 and boots v4; system=v3 boots
  v3; STARFORTH_V4=0 builds v3 alone.  Board images write system=v4.
- Acceptance (CLAUDE.md): the three ISAs as built (v4, POST passed,
  V4_SYSTEM dict_hash equal) and make -C v4 test-32.  v3 is not part of
  it.

Acceptance run: amd64, aarch64, riscv64 -- PARITY:V4_POST 538/538,
dict_hash=0xe5a57f3eb72ff94a on all three, no unknown word; test-32: 30
suites, 0 failures.  The SER5 image under OVMF boots v4 as built, v3 after
the one-word edit.  README, BRINGUP, FABRIC-3 XLIII, the register updated.

# Dead ideas and revised claims
A register, started 2026-10-14 by the docs triage. An idea that was abandoned, or a claim that
turned out wrong, keeps its documents (archived, with a header) — this page says, in one place,
what is no longer true, since when, and where the decision is recorded. Add to it whenever a
document is superseded or a claim corrected.
## Dead — abandoned, removed, or never adopted
| Idea | Since | What happened | Recorded in |
|---|---|---|---|
| L4Re / Fiasco.OC as a platform target | mid-2026 | Removed as an active target; LithosAnanke is its own kernel. | `.claude/CLAUDE.md` (Project Overview); docs archived in `working/archive/dead/l4re/` |
| The `hal_*` interface contract and its migration plan | flagged 2026-10-09 | Never adopted; the kernel grew its own HAL. | `working/archive/dead/hal-target-contract/`; the HAL as built: `kernel/src/hal/README.md` |
| ACL "Rolling Window of Truth" (`ACL-RECHECK-RW`) | removed 2026-07-08 | Dead code from the start: `acl_recheck()` only ever looked up `ACL-RECHECK`. | `fabric/FABRIC-1.md` §M–T |
| The Hermes VM and FORTH messaging (`messaging.4th`, `MSG-TICK`) | 2026-09-22 | Messaging moved into the kernel as kernel-Hermes; the Tripod is Hera / Artemis / Hestia. | `fabric/FABRIC-3.5.md`, `FABRIC-3.6.md`; old docs in `working/archive/superseded/2026-08-tripod/` and `.claude/HERMES.md` (frozen) |
| Running a VM's messages from Hera's idle loop (a second delivery path) | 2026-10-14 | One path: a VM takes its own messages on its own turn. | `fabric/FABRIC-3.md` §XXXVI |
| Word-ACL elevation on request (`ELEVATE-GRANT`, `KH-ELEVATE-SEND`) and Zuse's eligibility list | 2026-10-14 | Ruled not needed: privilege comes from the drive. Removed, with the hole it carried; the list's disk area is reserved, unused. | `fabric/FABRIC-3.md` §XXXVII; `fabric/FABRIC-3.7.md` (closed) |
| A knowledge factor for identity (PIN, passphrase) | 2026-09-23 | Built, tested, reverted: "there's only the drive." | `fabric/FABRIC-3.7.md` §4 |
| Defending against a byte-for-byte cloned identity drive | 2026-09-23 | Accepted by design, not a gap. (Copying from *within* StarshipOS is blocked.) | `fabric/FABRIC-3.7.md` §4 |
| The StarForth-era roadmap (VM -> kernel -> OS -> FPGA, 2025-12) | flagged 2026-08-26 | Overtaken; the architecture and terms it uses no longer exist. | `working/archive/superseded/2025-12-14-starforth-roadmap.md`; now `reference/ROADMAP.md` |
| The complete 2^6 factorial DoE | flagged 2026-10-09 | Obsolete. | `working/archive/superseded/factorial-doe/` |
| "Everything is a VM" system architecture, draft 0.1 | 2026-01-27 | A vision draft; what was built is in the FABRIC record. | `working/archive/historical/2026-01-27-system-architecture-draft.md` |
**Deferred, not dead:**
- **The multiuser/multitasking DoE campaign** (`fabric/FABRIC-3.md` §XXXIII–XXXV). Deferred past
bare metal, 2026-10-14. Its original 30-reps-per-cell design (about 10.3 days) had already been
replaced, in §XXXIV.4, by a segmented per-ISA design.
- **Keyboard VMs.** A concept only (2026-10-14), not designed.
## Revised — claims that were corrected
| Was | Is | Since | Recorded in |
|---|---|---|---|
| ACL overhead "+0.0054%–+0.0088%" (the "ACL-RWT" campaign) | **+0.0603%**, the live ACL-TTL mechanism, CV 0.000% | 2026-08-21 | `fabric/FABRIC-1.md` §T |
| Kernel version 2.0.1 | rolled back to 2.0.0 on 2026-09-04 (2.0.1 names the SER5 hardware line), now **2.1.0** (tag `v2.1.0`) | 2026-09-22 | `fabric/FABRIC-3.md` §I.2; `kernel/Makefile` |
| Capsule blocks must be in `[2048, 5120)` | **2048 or more**, no upper bound | 2026-10-05 | `v4.0.0/NUCLEUS.md` §5.2 |
| A capsule block is a 1024-byte budget | **64 characters x 16 lines** (`mkcapsule --lint`) | 2026-09-19 | `.claude/CLAUDE.md` (block format) |
| Parity baseline: 530 words, hash `0x08873e0f44b7cb2a` | **526 words, `0x82f4ae7cb2e2d424`** (elevation words out, `LOG-FLUSH`/`LOG-SHOW` in) | 2026-10-14 | `fabric/FABRIC-3.md` §XXXVII, §XXXVIII |
| Identity drives attached together are dropped (§XIV) | **no longer reproduces**, all three ISAs | 2026-10-14 | `fabric/FABRIC-3.md` §XIV |
| `THRU`/`LOAD` lose the rest of their line | **fixed** | 2026-10-14 | `fabric/FABRIC-3.md` §XXXIV.1 |
| The log ring's growth is "safe regardless of wrap state" | **it was not**; fixed | 2026-10-14 | `fabric/FABRIC-3.md` §XXXVIII |
| The Pi 5's GIC is under `/axi` with two-cell addresses; its framebuffer address needs `& 0x3FFFFFFF` | **under `/soc`, one cell**, read through `ranges`; the address **goes through `dma-ranges`** | 2026-10-14 | `fabric/FABRIC-3.md` §XXXIX |
| The old elevation path passed a raw cross-VM address | **it copied text** (the narrower real gap was a `"` in a name) | 2026-09-22 | `fabric/FABRIC-3.7.md` (its own correction) |
| Kernel builds boot v3 (v4 only with `STARFORTH_V4=1`, then v3 not at all; board images v3 unless `system=v4`) | **every build carries both and boots v4** unless `system=v3` -- v3 is being retired | 2026-10-14 | `fabric/FABRIC-3.md` XLIII (revised) |
| `.claude/ARTEMIS.md`, `HERMES.md`, `TRIPOD.md`, `CONSOLE.md` describe the system | **frozen as record**, superseded by FABRIC-3.5/3.6 | 2026-09-22 | `.claude/CLAUDE.md` (top) |
**Resolved 2026-10-14:** the top-level `README.md` was titled "LithosAnanke v2.0.1" (the SER5
hardware line's version) while the kernel is 2.1.0; Captain Bob ruled it rewritten -- it now
describes the system as it is (Tripod Hera/Artemis/Hestia, kernel-Hermes, 1052-test POST, both
systems on every board image, v4 the default).
