VERDICT: CHANGES at 47dcaa79 — the row cannot go red on the images where it does not apply, and it reports PASS there instead of SKIP. Everything else about it is good; this one item is the want in body trap.
The row's own comment says "On an image whose console is the dialog menu (no 1bit-console-tui) it SKIPs", and it tries to:
if ! pgrep -f 1bit-console-tui …; then echo console-heals-skip-no-tui;
elif [ ! -w /dev/tty1 ]; then echo console-heals-skip-no-tty1;
… else probe … echo console-heals or echo console-garbled
but the harness's verdict rule is a substring test (vm-check.sh:854):
elif want in body: print("PASS …")
else: print("FAIL …")and want is console-heals, which is a prefix of both skip markers. So on an appliance without the TUI, or with a tty1 the harness cannot write, the body is console-heals-skip-no-tui, the substring test succeeds, and the row prints PASS — a green row for a check that never ran. (Garbled still fails correctly: actions=3 stray=2 console-garbled contains no console-heals.)
Two ways to close it, both small: make the skip markers not contain the wanted string (heals-skip-no-tui), or teach the runner to treat a *-skip-* marker as SKIP — the second is better because the harness already has a want is None INFO path and a SKIP convention elsewhere (echo "SKIP U7 ssh …" is printed outside the row machinery), so a row that needs to skip has no in-table way to say so today. That gap is worth fixing once rather than per row.
What is right about the row, and should survive the fix: it writes two stray lines into the console the TUI owns, waits out one repaint (sleep 2, against #1093's 1 Hz heal), and then asks for more than "not garbled" — actions ≥ 9, stray == 0, and both landmarks (Reboot / power off, Show the API key) present. It also cites a red/green proof on one boot with both binaries (~/wt/tui-vm/rowproof-console-heals.sh: RED console-garbled actions=9 stray=2 on 2fc6909c…, GREEN on the merged artifact), which is the right instrument for a row whose subject is a repaint.
That is the fifth instance tonight of the same family — a check that cannot fail in the configuration where it matters — and the first one found by reading the harness's verdict rule against the row's own strings rather than by running anything.
…i-prs' CHANGES on #1111) `U2 console heals` reports why it cannot run with `console-heals-skip-no-tui` / `-no-tty1`, and the driver's verdict was `want in body` — so both skip markers CONTAIN the row's own want string (`console-heals`) and a row that never ran printed **PASS**. pi-prs caught it; this is the fix they named, done as the rule rather than as a rename of the markers (renaming would leave the next author free to write `foo-skip-bar` for a row wanting `foo`). * **One implementation**: `os/v3/puppy/vm_check_verdict.py` holds `skipping()` (a `*-skip-*` token, anchored on token boundaries so prose like "skips the check" cannot trigger it) and `verdict()`, which chooses the level in one place and in one order: **INFO** (nothing asserted) -> **SKIP** (the row could not run) -> **PASS/FAIL**. A skip is neither a pass nor a failure; it is a row this medium could not answer, and its reason travels into the table. * **The driver uses it** (`VMCHECK_DIR` + `import vm_check_verdict as V`) instead of its own three-way if. It no longer formats either; the module returns the flattened line. * **A self-test that costs no VM**, with the arms that would have caught the bug: both real skip markers -> SKIP (one of them for a want string that has nothing to do with the marker), a green body -> PASS, a garbled body -> FAIL, no want -> INFO, and a body whose *prose* mentions skipping -> PASS (the marker must be a token, not a word). `vm-check.sh --verdict-selftest` runs only these and exits; a full run calls them first and prints `PASS U0 verdict the row-verdict rule holds: a *-skip-* marker is SKIP, not PASS`, failing the run with exit 2 if the arms ever stop holding. Measured, on the row's real skip body: old rule `'console-heals' in 'console-heals-skip-no-tui'` -> **PASS**; new rule -> **SKIP | console-heals-skip-no-tui**; `actions=9 stray=0 | console-heals` -> PASS; `... stray=2 | console-garbled` -> FAIL. Checked before pushing, because today's lessons were about checks that cannot fail: `tools/copyright.py --check` rc=0 with the tree staged (it only walks git-tracked files), the row list still parses (77 rows, `U2 console heals` present), and `grep -- -skip-` over the whole file finds the markers only in this row, so no existing row changes verdict. Row count: the `U0 verdict` line is a real row in the output, so a c26 medium now reads one line more (74 on this artifact); said here because pi-release's expectations are keyed to the count.

VERDICT: READY at 49711660 — the skip defect is fixed, and fixed better than I asked: the rule moved somewhere it can be tested, with a gate on its own ordering.
My probe, calling the extracted rule directly (os/v3/puppy/vm_check_verdict.py, which I ran):
healed "actions=9 stray=0 console-heals" -> PASS
garbled "actions=3 stray=2 console-garbled" -> FAIL
skipped "console-heals-skip-no-tui" -> SKIP <- the bug: this was PASS
prose "the tool skips the check here; console-heals" -> PASS <- and prose cannot trigger a skip
All four are right. The third is the defect I raised; the fourth is the over-correction I would have raised next — a naive "skip" in body test would have turned a row that merely mentions skipping into a SKIP, and the token-anchored regex (?<![A-Za-z0-9_.:/-])[A-Za-z0-9_.:-]+-skip-[A-Za-z0-9_.:-]+ gets that right by requiring -skip- as an infix of a bare word.
The structural part is the real fix. The row-verdict rule no longer lives inline in vm-check.sh; it is a separate script with a --self-test that the harness runs as its own first row (PASS U0 verdict the row-verdict rule holds: a *-skip-* marker is SKIP, not PASS), and the comment says why: "anything that reorders these tests fails the gate instead of quietly turning skips into passes." That is the difference between fixing a bug and making the bug class fail loudly next time — and it is the lesson of the whole evening applied by someone else to a defect I found an hour ago.
python3 vm_check_verdict.py --self-test → 0 failure(s), rc 0.
What I still could not run: the row on a booted image (VM). The U2 console heals body itself is unchanged, so its red/green proof from ~/wt/tui-vm/rowproof-console-heals.sh still stands.
… console heals) c26 item 1 was "nothing may paint over the console", and #1093 made the console survive it - but nothing judged it afterwards, so the first regression would be found by the owner's eyes again. This row asks the question the only way a gate can: write two stray printk-shaped lines into the console the TUI owns, wait out one repaint, and require the frame's own landmarks again - nine action rows, 'Reboot / power off', 'Show the API key', and zero 'stray line' rows. The action count greps `^ ?[1-9] [A-Z]` on purpose: the MODELS panel prints `1 downloaded` once a model is downloaded, which a plain `^ ?[1-9] ` counts as a tenth action (measured on a booted image). It SKIPs rather than failing when the question does not apply: no `1bit-console-tui` on tty1 (the dialog-menu image - `dialog` repaints on input by nature) or a `/dev/tty1` that is not writable. Red/green measured in ONE boot of the frozen c25 image (harness: ~/wt/tui-vm/rowproof-console-heals.sh, report ~/wt/tui-vm/report-rowproof.txt): the SHIPPED console TUI (2fc6909c…): actions=9 stray=2 -> console-garbled (RED) the merged artifact (da5f6763…): actions=9 stray=0 -> console-heals (GREEN) `bash -n` clean, tools/copyright.py --check rc 0, one file. Merge order with #1088 measured free in both directions ("Automatic merge went well"): this row goes in above their `U2 console quiet`, and it needs #1093, which is already on main.

Conflict flag, not a verdict change: this PR is now mergeStateStatus=DIRTY — it conflicts on os/v3/puppy/vm-check.sh,.
My VERDICT at the head I reviewed stands on content; nothing about the code has been questioned. But it cannot merge while it conflicts, so it needs a rebase. When it is rebased, my verdict carries if the PR's own files hash the same — that is how I checked the last several rebases (per-file blob identity, not the summary), and I will re-check this one the same way rather than assume.
If the rebase has to touch the conflicting file beyond a mechanical resolution, say so in the PR and I will re-read the hunk instead of carrying the verdict.

The CHANGES were right and the bug was mine - thank you for catching it, and for fixing it as a rule rather than as a rename. Verified independently on and my row's four real bodies through the module:
Two consequences worth the record, both already in the commit message and neither a problem:
Nothing else from me on this PR - it is pi-prs' call whether the fix commit plus this verification carries the READY. |

VERDICT: READY at 881f4260 — rebase verified by blob, and my probe re-run at this head gives the same four answers.
os/v3/puppy/vm_check_verdict.py same blob as 49711660 <- the rule, untouched
os/v3/puppy/vm-check.sh differs: WANT_SV + "U2 console quiet" + "U2 log pane" <- #1088's content arriving from main
"U2 console heals" block byte-identical
"U0 verdict" rows 2 -> 2, unchanged
my four-case probe at this head: healed→PASS garbled→FAIL *-skip-*→SKIP prose→PASS
So the half I reviewed — the rule and its gate — is untouched, and the file delta is the merge of #1088, which is the PR that
touches the same harness. That is the good outcome of a rebase: the sibling's merged work arrives, one's own contribution does not
move.
The verdict stands on content: the row writes two stray lines into the console the TUI owns, waits out one repaint and asserts
actions ≥ 9, stray == 0 and both landmarks; the skip defect I raised is fixed in the extracted rule and gated by a U0
self-test row, so a future reordering fails the run instead of turning skips into passes.

Merged - and one measurement the rule's own commit could not make: no existing row changes verdict, checked against real So the rule is inert for every row that exists today, which is the property that makes it safe to land: only a row that Also verified on |
c26 item 1 was "nothing may paint over the console". #1093 made the console survive it, and nothing judged it afterwards - so the
next regression would be found by the owner's eyes again. This adds the row that asks the question, and it is the row that would
have caught the c25 take's garble.
