feat(v4.0.0): POST passes and is part of the boot; U* and U/MOD
The boot is now nucleus, forth79.4th, POST, prompt, on both products. - forth79.4th: U* and U/MOD, the capsule's first colon definitions. They are in the FORTH-79 Required Word Set and neither v3 nor v4 had them. - post79.4th: 550 cases, 126 of the 130 required words. 443 are v3's with v3's result. The rest follow three rulings (2026-10-05): address- dependent cases are checked for count, not value; where v3 departs from FORTH-79 the standard's result is expected; words v3 has no case for get cases written by hand. v4/tools/post79_rules.py holds each exception with its reason and docs/v4.0.0/POST79.md lists them all. - every case starts from an empty stack, DECIMAL and FORTH DEFINITIONS - the boot requires POST's tally line with fail=0 Verified: tests=550 pass=550 fail=0 and identical PARITY lines on hosted amd64, aarch64 and riscv64 (make -C v4 hosted-check) and on bare metal, clean qemu with STARFORTH_V4=1, on the same three (logs/20261005-1619xx, -1621xx, -1625xx). A U/MOD broken on purpose fails five cases and stops the boot. make -C v4 test passes. Not shown: all words but those two are still assembled, so POST has so far tested the assembled words. Nothing was typed at a bare-metal prompt. Open: PAD 42 OVER ! faults on v4 (D-1). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

### 6.4 Generating the expected values
|
||||
|
||||
A script reads the v3 test modules, keeps the cases for Required Word Set
|
||||
words, pipes each line through the hosted v3 binary, and writes the
|
||||
`T{ ... }T` lines. It is a development tool, run when the cases change; its
|
||||
output, `post79.4th`, is committed and reviewed like any source.
|
||||
`v4/tools/mkpost.py` reads the v3 test modules, keeps the cases for
|
||||
Required Word Set words, runs them in one session of the hosted v3 binary,
|
||||
and writes `capsules/v4/post79.4th`. It is a development tool
|
||||
(`make -C v4 post79`), run when the cases or the rules change; its output
|
||||
is committed and reviewed like any source. Every case starts from the same
|
||||
state on both machines: empty stack, `DECIMAL`, `FORTH DEFINITIONS`.
|
||||
|
||||
### 6.5 Where POST does not take v3's word (ruled 2026-10-05)
|
||||
|
||||
`v4/tools/post79_rules.py` holds the exceptions, each with its reason, and
|
||||
`mkpost.py` writes them out as `POST79.md`, which lists every one.
|
||||
|
||||
1. **Address-dependent cases.** A case that leaves or prints a memory
|
||||
address is checked for the number of values it leaves, and for what it
|
||||
prints unless an address is printed. The values are not compared.
|
||||
2. **Where v3 departs from FORTH-79.** The expected result is the
|
||||
standard's. Where v3's line is not valid FORTH-79 (`>R` at the prompt, a
|
||||
single number given to `<#`), the line is rewritten so that it is.
|
||||
3. **Cases written for v3's machine.** A v4 address unit is a cell (D-1);
|
||||
cases that assume v3's byte addresses are rewritten in v4's terms.
|
||||
4. **Words v3 has no case for** get cases written by hand, with the
|
||||
standard's results. `U*` and `U/MOD`, which neither v3 nor the v4
|
||||
nucleus had, are colon definitions in `forth79.4th`.
|
||||
|
||||
Not tested: `KEY`, `EXPECT` and `QUERY`, which wait for the keyboard, and
|
||||
`QUIT`, which returns to the terminal without ` ok`.

# POST for the FORTH-79 Required Word Set: where it departs from v3
|
||||
|
||||
Written by `v4/tools/mkpost.py` from `v4/tools/post79_rules.py`; do not edit.
|
||||
Design: `NUCLEUS.md` section 6. The capsule is `capsules/v4/post79.4th`.
|
||||
|
||||
POST runs 550 cases. 443 are v3's, with what the hosted v3 binary did as the
|
||||
expected result. This file lists every other case, and why.
|
||||
|
||||
## 1. Rewritten for FORTH-79 (59)
|
||||
|
||||
v3 departs from the standard, or the case is written for v3's machine. v4
|
||||
follows the standard (standing ruling), so the expected result is the
|
||||
standard's and not v3's.

the two machines. The number of values left is checked, and what is

## 4. v3 cases left out (27)
|
||||
|
||||
| Case | Why |
|
||||
|---|---|
|
||||
| `EXPECT.zero_length` | reads the keyboard |
|
||||
| `EXPECT.one_item` | reads the keyboard |
|
||||
| `EXPECT.empty_stack` | reads the keyboard |
|
||||
| `FORGET.nonexistent` | forgets a word of the system |
|
||||
| `FORGET.protected` | forgets a word of the system |
|
||||
| `CONTEXT.modify` | damages the system on purpose |
|
||||
| `CURRENT.protect` | damages the system on purpose |
|
||||
| `QUIT.in_definition` | v3 did not get through it in one session |
|
||||
| `:.nested` | v3 did not get through it in one session |
|
||||
| `].basic` | v3 did not get through it in one session |
|
||||
| `ELSE.double` | v3 did not get through it in one session |
|
||||
| `THEN.extra` | v3 did not get through it in one session |
|
||||
| `CMOVE.bounds` | moves 1000 bytes over the system; v3 refuses by a bounds rule FORTH-79 has not got |
|
||||
| `WORD.empty_input` | v3's WORD does not take the next word from the input, as FORTH-79's does; see the WORD cases written by hand |
|
||||
| `WORD.space_delim` | v3's WORD does not take the next word from the input, as FORTH-79's does; see the WORD cases written by hand |
|
||||
| `WORD.newline_delim` | v3's WORD does not take the next word from the input, as FORTH-79's does; see the WORD cases written by hand |
|
||||
| `WORD.tab_delim` | v3's WORD does not take the next word from the input, as FORTH-79's does; see the WORD cases written by hand |

|
||||
| `WORD.skip_leading` | v3's WORD does not take the next word from the input, as FORTH-79's does; see the WORD cases written by hand |
|
||||
| `WORD.single_char` | v3's WORD does not take the next word from the input, as FORTH-79's does; see the WORD cases written by hand |
|
||||
| `WORD.long_word` | v3's WORD does not take the next word from the input, as FORTH-79's does; see the WORD cases written by hand |
|
||||
| `WORD.zero_delim` | v3's WORD does not take the next word from the input, as FORTH-79's does; see the WORD cases written by hand |

|
||||
| `PAD.usable` | OPEN: PAD 42 OVER ! faults on v4 -- PAD is a byte address and ! takes a cell address (D-1) |
|
||||
|
||||
## 5. Required words POST does not test
|
||||
|
||||
`KEY` `EXPECT` `QUERY` `QUIT`.
|
||||
|
||||
`KEY`, `EXPECT` and `QUERY` wait for the keyboard, which a boot cannot type
|
||||
at. `QUIT` returns to the terminal without `ok`, which the capsule loader
|
||||
takes for a refused line.
|
||||
|
||||
## 6. Where v3 did not do what its own table expects (6)
|
||||
|
||||
POST expects what v3 did, unless section 1 says otherwise.
|
||||
|
||||
| Case | |
|
||||
|---|---|
|
||||
| `+!.basic` | v3's table says no error, v3 raised one |
|
||||
| `+!.by_zero` | v3's table says no error, v3 raised one |
|
||||
| `+!.negative` | v3's table says no error, v3 raised one |
|
||||
| `+!.accumulate` | v3's table says no error, v3 raised one |
|
||||
| `HERE.after_comma~2` | v3's table says no error, v3 raised one |
|
||||
| `CREATE.long_name` | v3's table says error, v3 raised none |

`forth79.4th` holds no definitions yet: every word is still in the nucleus.
|
||||
**What this does not yet show.** `forth79.4th` holds two definitions, `U*`
|
||||
and `U/MOD`. Every other word is still in the assembled nucleus, so POST is
|
||||
so far a test of the assembled words. Moving them to the capsule, a group at
|
||||
a time with POST after each, is the next step (`NUCLEUS.md` section 8).
|
||||
|
||||
## POST
|
||||
|
||||
`capsules/v4/post79.4th` is v3's POST cases for the FORTH-79 Required Word
|
||||
Set, written by `v4/tools/mkpost.py` (`make -C v4 post79`): 537 cases in
|
||||
blocks 7000–7112, covering 111 of the 130 required words. Each case carries
|
||||
what the hosted v3 binary did with the same line — error or not, the stack,
|
||||
the length and checksum of what was printed — and v4 must do the same.
|
||||
`capsules/v4/post79.4th`: 550 cases in blocks 7000 up, covering 126 of the
|
||||
130 words of the FORTH-79 Required Word Set. 443 are v3's cases with what
|
||||
the hosted v3 binary did as the expected result. The other 107, and the 27
|
||||
v3 cases left out, are listed with reasons in `docs/v4.0.0/POST79.md`.
|
||||
|
||||
**POST does not pass yet, so it is not in the boot.** `make -C v4 post` builds
|
||||
the amd64 system with it (`-DV4_POST_AT_BOOT=1`) and boots it:
|
||||
- `make -C v4 post` boots the amd64 system: the quick check after a change.
|
||||
- `make -C v4 hosted-check` boots all three hosted ISAs and compares them.
|
||||
- `make -C v4 post79` writes the capsule again (`tools/mkpost.py`,
|
||||
`tools/post79_rules.py`); it needs the hosted v3 binary.
|
||||
|
||||
```
|
||||
PARITY:V4_POST tests=537 pass=439 fail=98
|
||||
PARITY:FAIL
|
||||
POST: FAILED
|
||||
```
|
||||
POST is FORTH: a harness of FORTH-79 words and two nucleus hooks, `(CATCH)`
|
||||
and `(EMIT-HOOK)`. It forgets itself when it has finished. The boot passes
|
||||
only on seeing POST's tally line with `fail=0` (`v4/system/boot.c`). A colon
|
||||
definition broken on purpose (`U/MOD` without its last `SWAP`) fails five
|
||||
cases and the boot stops with `POST: FAILED`.
|
||||
|
||||
The 98 are not yet sorted into v4 defects and differences that need a
|
||||
ruling. A first reading finds four kinds:
|
||||
Not tested: `KEY`, `EXPECT`, `QUERY` (the keyboard) and `QUIT` (it returns
|
||||
without ` ok`).
|
||||
|
||||
| Kind | About | Examples |
|
||||
|---|---|---|
|
||||
| The case prints or leaves a memory address, which differs between the two machines | 40 | `HERE`, `PAD`, `1 BLOCK`, `BL WORD`, `CONTEXT @ .`, `FIND` |
|
||||
| v3 departs from FORTH-79 and v4 follows the standard | 35 | `PICK` and `ROLL` count from 1; `<# # #S #>` take a double number; `LEAVE` ends the loop at the next `LOOP`; `>R` `R>` only inside a definition |
|
||||
| The case assumes v3's byte address units, where a v4 address unit is a cell (D-1) | 8 | `42 , HERE 8 - @`, `PAD 42 OVER !` |
|
||||
| Not yet understood | 15 | vocabulary cases, `LIST`'s layout, `16 BASE ! 255 .`, `321 EMIT`, cases v3 ends in an error and v4 does not |
|
||||
Open: `PAD 42 OVER !` faults on v4, because `PAD` is a byte address and `!`
|
||||
takes a cell address (D-1). FORTH-79 expects it to work. The v3 case for it
|
||||
is left out until that is ruled.
|
||||
|
||||
Required words with no v3 case, and so no POST case: `U*` `U/MOD` `?`
|
||||
`EXECUTE` `KEY` `EXPECT` `QUERY` `U.` `CONVERT` `'` `."` `LITERAL` `STATE`
|
||||
`COMPILE` `[COMPILE]` `(` `QUIT` `BLK` `79-STANDARD`. `U*` and `U/MOD` are
|
||||
in neither v3 nor v4.
|
||||
|
||||
Twelve v3 cases are left out: three read the keyboard, two forget a word of
|
||||
the system, two store to the search order, and five leave v3 unable to
|
||||
continue in one session (`mkpost.py` prints the list).
|
||||
|
||||
The boot passes POST only on seeing the tally line with `fail=0`
|
||||
(`v4/system/boot.c`); that no line was refused is not enough.
|
||||
The Required Word Set list in `tools/mkpost.py` was written from memory of
|
||||
the standard and has not been checked against the document.
