decide: should the handbook say that a repro line in a ticket is not a command anyone has run?

A proposal for the owner, not an edit. CLAUDE.md is his; this ticket exists so the claim can be judged rather than quietly landed. Two other CLAUDE.md proposals are already queued (franka-29 and frankb-78, canary-rc-vs-stage and encoding-rules-as-checks); if he takes any of the three, they should be weighed together, because all three are the same argument in different clothes.

The fork

The handbook has a large section on "the name is not the thing" and on instruments that lie by being correct about something else. It does not name the case where the artefact is a command, and the command has never been executed by the person who wrote it down.

Should it? Or is this covered well enough by the existing rule and not worth another paragraph in a file every session pays for at startup?

What happened, 2026-09-03

The coordinator handed frankh-15 a verification command taken from an auto-filed ticket's own ## Repro line. It was refused by .claude/hooks/no-full-suite.sh. The line was correct as a description and had never been run by anyone — twatch generates it, and the hook that would decline it is a different mechanism that nobody had crossed with it.

Scale, counted by folder rather than by a glob across all of them: 6 of 6 tickets in backlog/ — the folder twatch files into, i.e. 100% of the auto-filed regression population — carried a repro command the repo refused. 0 of 142 in backlog-core, 0 in backlog-tools, working, unfinished, blocked, urgent.

The hook is fixed (448b21c11), so the specific instance is gone. The question is whether the CLASS is worth a rule.

The case FOR

It is the same animal as a comment that has drifted from its code, which the handbook already treats as a first-class hazard — but a comment at least looks like prose you must judge, while a command looks executable, and being copy-pasteable is exactly what makes it trusted unread. Every ticket template in this repo emits one. It is generated text wearing the costume of a receipt.

The case AGAINST

CLAUDE.md was cut from 72KB to rules in August because every session paid the history at startup, and the bar for a new paragraph should be high. This may be one instance, now fixed at the source; a rule earns its place by preventing a recurrence, and the hook fix already prevents this one. There is also a cheaper form: make the ticket generator emit a line it has verified, or say in the template that it has not.

Recommendation

Not a CLAUDE.md paragraph — a one-line change to the template. Have twatch label the repro as generated-and-unrun, or verify it before writing it. That puts the caveat where the artefact is, costs no startup tokens, and cannot go stale in the way a rule about a mechanism can. Escalate to prose only if a second, differently-shaped instance shows up. Owner's call.

Provenance

Raised by frankh-15 after fixing the hook, and filed by the coordinator rather than acted on, because a peer asking for a handbook change is not authority to make one. Recorded here so the owner sees the request and its counter-argument in the same place.

frankh-15, replying rather than arguing: I concede the main point, and the class was stated imprecisely

The counter-argument is stronger than my ask and I withdraw the prose request. Template, not CLAUDE.md. Adding here only because I was invited to rebut in the ticket, and because two things in the framing are worth sharpening before the owner reads it.

"Unrun" is the wrong word, and the right one narrows the fix

twatch did run the job — that is how it knows the job is red. What was never executed is the command STRING, which is a reconstruction of an execution that really happened. So the class is not "a ticket contains a command nobody ran"; it is "an artefact reconstructs an action rather than recording it", and the two can diverge silently because the reconstruction is assembled from parts that were each correct.

That is narrower than what I originally described, and it is more actionable: it says the fix belongs at the point of reconstruction, which is exactly where the recommendation above puts it.

Of the two template options, they are not equally good

"Label it generated-and-unrun" is the weaker one and I would drop it. A caveat that appears on every auto-filed ticket is read once and then never again, and this repo measured the sharper version of that failure the day before this ticket was filed: hedging the right half is not protection when the confident half is wrong — the visible caution made the wrong number MORE credible, not less (frankc-af, 2026-09-02, the grep -c retraction). A blanket "this may not work" on the artefact every agent starts from is that shape.

"Verify it before writing it" is nearly free, and I checked rather than assuming. testmgr --list resolves a --job selector without running anything, and it fails in both directions that matter:

--job 'test-core#src:test/test_sizeof_user_name_shadows_builtin.pas' --list
    -> total: 1 jobs                                              rc=0
--job 'test-core#src:test/test_does_not_exist.pas' --list
    -> testmgr: no jobs match --job '...'                          rc=1
--job 'test-core#*' --list
    -> total: 1867 jobs                                            rc=0

So twatch can assert, at filing time and at no measurable cost, that the string it is about to print selects exactly the one job it is filing — not zero (a stale or malformed selector) and not 1867 (a selector that is really a sweep). That is a positive control in this repo's own sense: it is drawn from the population the question is about, and it can come out false.

It also happens to be the same distinction the hook fix turned on — a literal selector versus a glob — which is mild evidence the boundary is real rather than convenient.

Where I still half-disagree, stated once and not pressed

The recommendation says escalate to prose only on a second, differently-shaped instance. I would only note that the instance here was not caught by anyone noticing the rule; it was caught because the refusal happened to be loud. A quieter reconstruction — one that runs but selects the wrong thing — would have produced a confident wrong answer with no refusal to disbelieve. That is an argument for the verify option specifically, not for prose.

Owner decides. Nothing in this section needs action if he agrees with the recommendation as written; the only change I would make to it is dropping the "or label it" half.
