Severity is my judgement: +**H** can give wrong results or lose data in a path that runs today; **M** latent (not reached by the products +yet, or needs unusual input); **L** comments, naming, hygiene. + +## v4 engine (`v4/src`) — read: exec.c, node.c, stack.[ch], fabric.c, wire.c, manage.c, heat.c +Overall: careful C99. All arithmetic in `v4_ucell` (no signed-overflow UB), D-14/D-16 guards before every +opcode, the engine is libc-free so the kernel links it unchanged. Comments state the rulings they implement. + +- **M — `manage.c` pops and pushes without checking stack depth.** `v4_manage_serve()` takes 1–4 arguments + with `v4_dstack_pop()` and never checks `n->ds.depth` (contrast `v4/system/blocks.c:99`, which refuses a block + request with too few values — added after the MESH step-6 review found the same hole there). `v4_dstack_pop` + on an empty stack does not fault; it returns whatever is in the ring. So `NODE-KILL`, `NODE-WIRE`, + `NODE-SLEEP` etc. typed with too few values act on stale numbers, and the result pushes can saturate a full + stack silently. Latent today: only tests call it (products are one node, MESH steps 8–9 not built). +- **M — `1u << (V4_PORTS + k)` in `fabric.c:293` (look_about)** is undefined once `V4_PORTS > 16`; nothing + checks it at compile time. This is exactly issue #20, confirmed in code. `node.h` defaults `V4_PORTS` to 8. +- **L — stale comments, already known:** `stack.h` lines 20–30 ("no overflow detection, and there never will + be") (DATASHEET §13 item 4) and `stack.c` lines 27–30 say the same and hardcode "mod 8" though the ring size + is a build parameter (host node 30/31). +- **L — `heat.c` `call_index()` comment reads as an unfinished thought** ("hash-mod or just take low bits? Or + simply if in range use it", "ignore for now? Or clamp?"). The code is the documented D-6 stand-in, and ENGINE + step-4 Part A (A1) plans to delete `call[]`, the freeze mask and `v4_heat_on_call` — Part A not started. + Under the "no TODO-shaped comments" standing rule this comment is exactly the kind that should not stand. +- **L — `node.c` store/fetch compare against attach registers that are `-1` when detached** ("no valid address + equals"). Safe for opcode paths (addresses are checked first) but a direct C caller passing `-1` would hit the + console/stack-register branch. Only reachable from C. +- OK, checked: branch target page-relative (iword), `unext` restart without refetch, resume after blocking, + fault cancels resume, store refused by the node does not advance A/P (the 11-02 review fix `fd208825`), + wire put/take/move all-or-nothing, queue pool free list, wire cut gives queues back at both ends. + +### manage.c finding — confirmed latent (2026-11-11) +`v4_manage_serve` has no caller outside `v4/tests/test_manage.c` (grep of kernel/src, v4/system, v4/tools). +`boot.c:266` serves only blocks and the kernel's word table. test_manage.c tests refusals and depth *after*, +never a request made with too few values. So: real hole, not reachable from a product today; becomes +reachable at MESH steps 8–9. A test written first (Bob's rule) would show it. + +## v4 system (`v4/system`) — read: boot.c run_line request loop, post.c judge loop, blocks.c guards +- **L/M — `boot.c` run_line, DONE path:** after the text ends, `for (i < 4096u && !doing && !stopped && !asking) + boot_exec(b)` — if the node has not settled in 4096 steps the line is reported done anyway, with no sign. + Bounded, but a silent cut-off (the method's dominant failure mode). Worth a named check or a comment of why + 4096 is enough. +- OK: unknown kernel request → error 12 (D-18), not ignored; port with no one → V4_ERROR_NO_ONE; step limit + → STOPPED; POST reads the stack before judging, resets it, reports a stopped node and ends POST. + +## kernel v4 path (`kernel/src/v4`) — read: sk_v4.c, sk_v4_mint.c, sk_v4_marker.c, sk_v4_grow.c, identity.c 160–320 +- **M — MINT-ZUSE says "failed -- nothing changed" when something has changed.** `failed()` is called after + `gpt_write_one()` has rewritten the stick's GPT and after the first 32 Forth blocks are zeroed, so a mint + that fails at `capsule_zuse_boot_genesis_mint`/read-back/marker write has already erased the stick. The + message is false on those paths (only the size and YES refusals are truly "nothing written"). +- **L — secrets left in stack memory on failure paths.** `sk_v4_mint_zuse` wipes `seed`/`rseed` only on success; + every `return failed()` after the mint leaves them. `sk_v4_genesis` (identity.c ~237) never wipes `seed`/`rseed` + at all, while `sk_v4_real_zuse_arrived` wipes `seed`. Inconsistent; the seed is also kept in `g_zuse_seed` + by design, so this is hygiene, not a leak path I can show. +- **L — fatal paths spin.** `sk_v4_run` ends in `for (;;) { }` on "not started", "did not let go of POST's + blocks" and "stopped on a fault": a 100% core spin, the thing #151 fixed at the prompt with `arch_halt()`. +- **L — `sk_v4_grow.c` `dev_rw4k`: `(uint32_t)devblock * 4u`** truncates for volumes past 4 TiB of 1 KiB blocks. + Unreachable with the 256 GiB Artemis cap (`STICK_ARTEMIS_CAP_GIB`), so latent only. +- **L — `sk_v4_serve` ignores request numbers other than 1 and 2** silently; safe because boot.c only calls it + for 1..word_count (2), but the guard lives in the caller. +- OK: marker v1/v2 read with CRC and `has_real > 1` refused; marker written only after mint read-back + (STICK.md 6 order); line editor's over-long line refused whole (not truncated and run); logout ends a + waiting line (Bob 2026-10-26); size message buffer sized right (28 bytes incl.

Heat and K arithmetic stay 64-bit. +- Physics split: virtual heat (deterministic) decides WHAT runs; physical power (XADC) decides WHEN. +- Path: hosted golden model → hosted mesh → Verilator co-sim → FPGA (2×2 on PZ7020) → ASIC (Tiny Tapeout, IHP SG13G2). +- §14 definition of done; §15 three products (ruled 2026-10-03); §16 acceptance: v4 equivalent to v3 at any + point; every ISA hosted and bare metal reaches `ok`. `make -C v4 test` is a development check only. + +### ENGINE.md +- Rule (2026-10-05): v4 is exactly like v3 functionally up to the first prompt.

No capsule for any of them. + The first node keeps the name Hera. No identity drive = headless; console only once a drive is in. + 2026-10-26: "Gate first" (identity gate before the rest of step 4). +- Interface a node must answer (§3): interpret a line; char out; ask the kernel (blocking port write, + `KERNEL-WORD`); stacks/dictionary from the kernel side; the hook at `call`; error; tick; dict hash. +- §3b ruling "A": word code lives on the node, its accounts live in a kernel record, joined by word ID. +- §3a: multiuser, multitasking, hybrid preemptive/cooperative. A node can stop between any two instruction + words (`v4_exec_step_word`). Hera decides which nodes exist and are awake, not whose turn it is. +- §3d: nodes born empty, first thing received is a capsule of F18 code.

Genesis marker version 2 holds both keys. +- `system=v3` is refused on a stick. Standing rule: "QEMU and bare metal ALWAYS hold parity." +- Every `clean qemu` boot attaches a fresh GPT data stick over xHCI, so every acceptance run is a first boot. +- §11 increments: 1–5a done (5a done 2026-11-10, #92); 6 pull/replug + flush (#93), 7 splash + progress bar (#94), + 8 acceptance moves to the stick boot (#95) — open. +- Known and accepted: the system stick stays a master key (fallback can mint a new Zuse). + +### V3-PARITY.md (gap record, started 2026-10-05) +- Two rulings: v4 = v3 up to the first prompt; "I would never stub, simulate or develop outside of functional, + as-intended code.

Invariant: an unattended birth must + never touch the console-pairing global (would open a prompt with no human present). No C capability bit — + ACL policy belongs in `ACL.4th`. +- §XXXII.3–.6 error-handling audit of the kernel-only words (v3): 105 `vm->error = 1` sites triaged, 75 silent + ones given diagnostics in 7 batches. Rules that came out of it: an interactive command's direct reply goes to + the console; everything else goes through `log_message()`; in a function, match the convention its other + guards already use; `defer_words.c` is the model (report, then fault). `SWITCH-MARK-WORK` and `VM-HEAT` must + never error (hot path). Found two real NULL-deref guards in `vm_compile_call`/`vm_exit_compile_mode`. + The vendored `word_source/` files (e.g. `memory_words.c` pre-checks in `@`/`!`) were left for FABRIC-4. +- §XXXII.4 log ring eviction is level-aware (ERROR/WARN protected); `log_region_append()` returns 0 / 1 + (dropped by design) / -1. `LOG-FLUSH` built later (10-14, §XXXVIII). +- §XXXIII (09-16) multiuser/multitasking DoE design (issue #58, deferred past bare metal): factors + concurrency 2/4/8 × workload uniform/heterogeneous; "rule of 3's" in every DoE.
