fix(v4.0.0): storage -- what the review of step 6 found
A block request with fewer than two values on the stack is refused; it had acted on whatever the stack ring held and stopped the node. Bare metal: when the kernel's chain takes the place of POST's block RAM the node's two buffers are emptied, so it no longer holds POST's copy of a block; and the chain's fast RAM is cleared, so a node cannot read what was in the kernel's heap. blocks.c is built with each test under that test's own warnings and sanitizers; it had been left out of both. The hosted link cleans its object directory first: it had linked the withdrawn store_v3.o left there from the day before. node.h and DECOMPOSITION.md D-19 no longer describe the message device or the four registers as current. MESH.md 8.5 records two findings for ruling: a node's own copy of a block, and a block read over a node's code. From a clean build: make -C v4 test, sanitize and hosted-check pass; amd64, aarch64 and riscv64 boot, POST 538 of 538, same hashes, blocks 1 and 2047 clean at the prompt: logs/20261007-085017, -085254, -085636.

| **D-16** | Stack overflow and underflow; `DEPTH`, `PICK`, `ROLL` (ruled 2026-10-04; revises D-2). | **Guarded: a stack fault.** Each stack counts what it holds. Before every opcode the node checks that the stacks hold what the opcode takes — including a `T` or `S` it only reads — and have room for what it leaves. If not, the opcode does nothing and the node faults exactly as for a bad address (D-14), to that kind's handler: `Stack overflow`, `Stack underflow`, `Return stack overflow`, `Return stack underflow`, then ` ERROR` and the prompt. **Every fault, D-14's included, empties both stacks**: the handler does not return, and what a word stopped part-way has left on the data stack is of no use to its caller. (v3 keeps what the failing word had not taken, and names the word: `DROP: Stack underflow`.) The fault handler is a table of five words, one per kind, each a jump (`(FAULTS)` in `v4/capsule/quit.v4`). Two registers (§7) are all a programme sees of the stacks: `DSTACK-DEPTH` and `RSTACK-DEPTH` read as the depth, and a store to one empties that stack. There is still no stack pointer and no address for a stack cell, so `SP@` and `SP!` stay retired; `.S` waits for number output to reach the capsule. The sizes were unchanged by this ruling, 10 and 9 (D-17 then deepens the host node's): one more value, or one more level of call, is now an error message where it used to be silent corruption. Executed on the golden model (2026-10-04): `tests/test_exec.c` for every opcode at every depth of both stacks, `tests/test_host_quit.c` from the prompt. |
|
||||
| **D-17** | Stack sizes on the host node (2026-10-04, following D-16). | **32 values and 32 return entries on the host node; a mesh node keeps the F18's 10 and 9.** Once the stacks are counted (D-16) their size is a parameter of the node, like its memory, and the host node is the one that runs the interpreter and the compiler underneath the user's programme: at 10 and 9 the prompt left a programme about six values, and `/` could be used only four words deep. The mechanism is the same at both sizes — top registers over a ring — and so is every word's definition. v3's stacks are deeper still. In the golden model the sizes are `V4_DATA_RING` and `V4_RET_RING` (`stack.h`), set for the host-node tests in `v4/Makefile`. |
|
||||
| **D-18** | Every other error (ruled 2026-10-04: "guard all errors"). | **A word that finds an error raises it, and the line ends there.** The word takes its own arguments off the stack and stores an error code in `NODE-ERROR` (§7). On a node with a prompt that store is a trap, a sixth kind of fault beside D-14's and D-16's: nothing after it executes, the return stack is emptied, and the prompt prints the code's message, ends any definition that was open, prints ` ERROR` and waits for the next line. Unlike the other faults it leaves the data stack as the word left it. The codes: 1 `Negative count` (`CMOVE`, `TYPE`), 2 `Not a number` (`NUMBER`), 3 `Number too long` (`HOLD` into a full buffer), 4 `Not a character` (`HOLD`), 5 `Dictionary full` (`,` `C,` `ALLOT`, any defining word), 6 `Name missing` (a defining word with nothing after it), 7 `Control structure mismatch`, 8 `Control structures too deep`, 9 `Shift count out of range`, 10 `Protected word`, 11 `Division by zero` (`Q./`), 12 `Argument out of range`, 13 `Block out of range`, 14 `No block is being loaded`, 15 `Deferred word not set`, 16 `Not a word`; −1 means the word printed its own message (`UNKNOWN WORD: 'xxx'`, `xxx: compile-only`). Before this ruling these set the flag and the line ran on to its end. v3 stops at once too; its messages name the word (`LOOP: missing DO`) where v4's name the fault. With the trap not attached `NODE-ERROR` is plain memory and the word returns, which is how the words are tested below the prompt. D-11, D-12 and D-13 said "set `NODE-ERROR`"; on a node with a prompt that now means this. Executed on the golden model (2026-10-04): `tests/test_exec.c`, `tests/test_host_quit.c`. |

| **D-19** | Block storage on the golden model (2026-10-05). | **Four memory-mapped registers on the host node, until the mesh carries the storage service.** `BLOCK-NUMBER`, `BLOCK-ADDRESS` (the word address of 256 cells), `BLOCK-COMMAND` (a store of 1 reads the block into those cells, 2 writes it from them) and `BLOCK-STATUS` (0 when the command worked, −1 for a block the device has not got or cells not all in memory). A block is 1024 bytes: 256 cells, four bytes to a cell, the first byte lowest, at either cell width. This is the console's arrangement (§7) applied to storage; like it, it is the model's stand-in and not the mesh protocol, which §5.11 still leaves to the device node. |

- **A node keeps its own copy of a block.** `BLOCK` gives the address of
|

one of the node's two buffers, and the kernel is asked only when a block
|
||||
is not in one. In v3 a VM's `BLOCK` gives the kernel's buffer, so every
|

VM sees one copy. Here, if node A has block *n* in a buffer and node B
|

writes it, A goes on reading what it had; and if A then does `UPDATE` and
|
||||
`SAVE-BUFFERS`, all of B's block is overwritten. One node alone cannot
|

see this, and the unit test's readers had never held the block they

read.

- **A block read over the node's own code.** The kernel checks that the

256 cells are in the node's memory and nothing more, so a request made

by hand with an address in the nucleus overwrites it and the node stops.
