What is new +is forge's `9878f12` (`tools/selftest_sweep.py`, Q93 refactor), and since Q93 is an item **I** opened at +`d56105a`, it gets verified and closed here rather than left to the commit message. Every figure below is from a +fresh anonymous clone at `9878f12` (`9878f1289b8487473a42c6347f6b5e684ce2485a`), run outside the repo, plus one +checkout of `f400640` for the before-state, between 15:00Z and 15:25Z. + +## 0. My own mistakes first + +1. **The false-green in §4 is my spec's fault before it is forge's.** Q93's done-means said "the malformed-input + probe asserts the *contract* (exit 2, empty stdout, non-empty stderr)". Forge implemented something close and + in one respect better (either stream may carry the message — `tool_map.py` prints its refusal to stdout, so + requiring stderr would have been a second prose pin). But I never asked for the one thing the removed pin was + quietly doing: checking that the refusal is **about the input**. `rc 2 + one line + no traceback` is also what + Python's `argparse` prints when a flag is renamed. So a tool whose CLI has drifted reads clean on both axes. + That is a hole in the item I wrote, and I am filing it as an item rather than calling the closure wrong. +2. **"One negative cell per shape — a tool that refuses with unexpected prose" was ambiguous and I wrote it.** + Read one way that cell should be red (prose that does not describe the fault); read the way forge took it + (c26), it is green by design.

Verified at the judge directly +too: `judge_malformed(2, "usage: … error: unrecognized arguments: /tmp/x", 2, None)` → `{'verdict': 'OK', +'contract': 'refusal'}`; the same for `rc 2, "crash: config missing at /etc/foo"` — a refusal for the wrong reason +is indistinguishable from the right one. The **read-refusal** axis has had this blind spot since it was written +(it has no prose pin at all, and it stayed 27/27 green on the mutant at *both* heads); Q93's change is that the +malformed axis joined it, having until today been the one place CLI drift could not hide. + +**Filed as Q97.** Not a reason to hold Q93 open: the two defects Q93 named are fixed and measured, and the +closure is real. But "unexpected prose" and "the tool did not receive the input at all" are different classes, +and only one of them is now graded. Shape of a fix, one line: refuse to grade a refusal whose message matches +`^usage:` / contains `unrecognized arguments` / contains `error:` on the argparse pattern — or, more in the spirit +of the item, require the refusal to name the input path it was given, which the two citation tools already do. + +## 3. Two smaller residuals, and one wrong figure in the report + +- **The docstring states a contract the code does not enforce.** It says "one non-empty message on either + stream". The code checks only that `out + err` is non-empty: `judge_malformed(2, "l1\nl2\nl3\n", "extra\n", 2, + None)` → `OK, contract=refusal`. Twenty lines of noise pass. Either the sentence narrows to "some message" or + the code counts lines and streams. +- **The verdict line can assert a pin it never read.** `--tools-dir tools/` prints `pin: not graded (…)` on its + own line and then `verdict: rc 0 -- clean: … **pin 0 drift**`; the ungradable case prints `verdict: rc 2 -- + could not grade: pin ungradable (… **pin 0 drift**)` — one line saying "ungradable" and "0 drift" in the same + breath. Cosmetic, but this is now the single line a reader trusts for the run's disposition. +- **`SELFTEST_SWEEP_Q93_REFACTOR_VERIFICATION.md` says `malformed-input: 27 probes` twice** (lines 104 and 114). + The committed `wizard-work/forge/Q93_LIVE_SWEEP_EVIDENCE.txt` says **26**, `MALFORMED_PROBES` has 26 rows, and + my run of the committed tree says 26.
