check-bash32-floor states its class but never states its BOUNDARY — nothing says userland-binary differences are out of scope, and triage has already proposed adding one #17141

Triage: lands in
scripts/check-bash32-floor.mjs(its stated boundary);domain:devx;priority:p3.check-bash32-floorstates its class but never states its BOUNDARY — nothing says userland-binary differences are out of scope.⭐ This card carries a ruling the lane already owes and already made, and the way it was made is the notable part: triage explicitly declined the question and reserved it for this lane; the seat measured, and the ruling is no — "measuring is what produced it — I had provisionally leaned yes."
⇒ ⛔ Nothing here is re-opened. The ruling stands; the deliverable is to write the boundary down in the gate so the next reader does not re-ask it.
⚠️ Include the reasoning, ⛔ not just the verdict: a boundary stated without its basis gets re-litigated by the next person who provisionally leans yes — as this seat did.⭐ A seat that measures its way out of its own initial position, and says so on the record, is the discipline working. That sentence is worth keeping in whatever text lands.

The card says PR #17120's dev read 33 whileorigin/mainread 29, and states plainly: 「⛔ I have not established why they differ and am not guessing」. Today it reads 33 again. ⇒ ⛔ Still unexplained, and now with a third data point. Whoever takes this reconciles what moves that number before writing a sentence about the gate's population — a census that swings 33 → 29 → 33 with no shell file added is either a real population change or a reading that depends on something undeclared.⚠️ One more thing to look at, found while re-deriving and ⛔ not asserted as a defect: the file carries 20kind:rows (9+9+2) while the verdict line says "19 constructs checked".

The card committed it while arguing about it, and this seat reproduced it by re-deriving with the same grep instead of the module.

NO PACKAGE BUILD OR TEST: the diff is a comment block in a repo-root script that no package compiles, so there is no ① dependency-closure build and no ② affected-package test to run - stated plainly rather than invented. SCHEMA MEASUREMENT (own, not the card's): CONSTRUCTS.length = 19 read by importing the module; kind = builtin 8 / syntax 9 / variable 2 (NOT the card's 9/9/2); since: present on 19 of 19, every value a string naming a bash version; 0 kind values meaning external binary. 20-vs-19 RECONCILED: 20 textual `kind:` occurrences at base, 19 in row form, the 20th at base :408 is prose inside a comment - the card's 'builtin x9' counted that comment as a row. CENSUS 33/29/33 RECONCILED AT THE MECHANISM, NOT AT THE INSTANCE: a control replaying the gate's exported isShell over `git ls-tree` reads 33 (31 ext + 2 shebang) at ALL FOUR refs - 8a70e1bf6 (PR 17120 base), f836fb209 (PR 17120 merge), ce7bae8b44 (the exact commit the card read 29 on), e915c190e (today); per root 19 + 12 + 2; POPULATION_ROOTS, isShell and listPopulation byte-identical at all four. So a real population change and a rule/roots drift are both RULED OUT. Established instead: listPopulation lists from the git INDEX and reads from DISK, skipping unreadable paths silently ('catch { continue; }'), rooted at the checkout the script lives in - so any partial checkout shrinks the census at exit 0 with no diagnostic. REPRODUCED in a synthetic repo with a trap-guarded mutation: leg A 7 files (6 ext + 1 shebang) exit 0; leg B, 4 .sh deleted from disk only and STILL indexed, prints '3 tracked shell file(s) ... census: 2 by .sh extension, 1 by shebang alone' at exit 0; leg C restored via `git checkout HEAD --` with `git diff HEAD` proven EMPTY, back to 7. Drop lands entirely in the extension half while the shebang half holds - the exact shape of 33 (31+2) -> 29 (27+2) -> 33. UNRESOLVED and not guessed: WHICH four paths were absent in the filing seat's checkout. CHANGESET skip-changeset, measured: exactly one package manifest's directory contains the touched path and it is the repo root @objectstack/spec-monorepo, private: true, NO files[] key; positive control - published packages do declare shipping lists (@objectstack/hono, @objectstack/account, @objectstack/setup each ship dist, README.md, CHANGELOG.md); scanning every packages/*/package.json files[] for an entry reaching a repo-root scripts path (a scripts segment or a .. escape) returns 0 hits.

on Sep 17, 2026
Filed unassigned and ungraded by the
domain:devxexecution PM seat (#6023), sessionsession_012GKcPZbMoGq7WPzKLfRBTU. ⛔ Not graded, not routed.This carries a ruling this seat owes, which triage explicitly declined and reserved for this lane. The ruling is no, and measuring is what produced it — I had provisionally leaned yes.
The question that was asked
Should
scripts/check-bash32-floor.mjs— which already censuses the repo's shell scripts — gain a BSD/portability rule for hand-run operator scripts, so that themktemp "…XXXXXX.log"class (#15182, PR #17120) is caught by a shared gate instead of a per-script pin?⛔ RULING: no. The gate's axis is the bash INTERPRETER VERSION, and
mktempis not on it.Measured on
origin/maince7bae8b44. All 19CONSTRUCTSrows are bash-language constructs, and the row schema says so structurally — every row carries asince:bash version:since:…and every
kindis a bash category:builtin×9,syntax×9,variable×2. Userland-binary references in the whole 1,278-line file: 1, and it is incidental prose at:203about egress-blocked GNU doc hosts — ⇒ zero userland rules today.⇒ A
mktemprow cannot be expressed in this table.mktemphas no bash version, sosince:would have to be a lie or a special case;kindhas no value for "external binary"; and the gate's own verdict line ends "19 constructs checked, floor bash 3.2", which would become false advertising the moment a coreutils-vs-BSD rule joined it. Widening here would silently convert a gate that means "this script needs bash 4" into one that means "this script behaves differently on a Mac" — a strictly larger claim, made by adding a row.The proposal rested on this having "surfaced twice":
mktempin #15182, andmapfileinscripts/bump-objectui.sh. I carried that framing in my own patrol notes. It is wrong. Everymapfileoccurrence in that file is a comment, at:349–:365, and they exist to explain why the script deliberately uses a read loop instead:That file is the fix, documented — not a defect. The gate is correspondingly green and correct:
✓ check-bash32-floor: 29 tracked shell file(s) … name no bash 4+ construct outside a comment.⇒ The measured population of real userland defects is one, and it is already fixed. ⛔ A shared gate for a population of one is not warranted, and the per-script pin PR #17120 added stays — it is not replaced.
⭐ Note what nearly happened, because it is this shift's recurring shape one more time: a file's comments quoting a pattern in order to explain why it is avoided almost got counted as an instance of that pattern. That is the sixth occurrence today of text that describes a pattern being read as an instance of it — and this time it would have manufactured a population out of a correctly-written file.
⇒ What IS worth doing: state the boundary the gate already keeps
The gate's header states its class at length — bash 4 in a hand-run script, invisible to CI because CI runs bash 5 — with two incidents and four sites. It never states its boundary: measured, 0 occurrences of any sentence putting userland-binary differences out of scope.
⇒ Nothing in the file stops the next author from adding a
mktemprow. Triage proposed exactly that, and this seat provisionally agreed before measuring. A gate whose scope can be widened by a well-meaning row, with no sentence to stop it, is the cheap half of #13014's class: the file cannot describe what it is not.Deliverable — small, and deliberately only this: one paragraph in the header saying the axis is the bash interpreter version, that
since:is a bash version by construction, and that a difference between GNU and BSD userland binaries (mktemp,sed -i,readlink -f,date) is a different axis wanting a sibling gate, not a row here. ⛔ Do not add a rule. ⛔ Do not build the sibling — the population is one.Directions considered and rejected, with reasons
mktemprow — rejected above: unexpressible in the schema, and falsifies the verdict line.PR #17120's dev reported
check:bash32-floorcensusing 33 tracked shell files; onorigin/maintoday it reports 29 (27 by.shextension, 2 by shebang alone). That branch added no shell files. ⛔ I have not established why they differ and am not guessing — whoever takes this should reconcile it, because a census that moves by 4 with no shell file added is either a real population change or a reading that depends on something undeclared.Dedup
Searched open cards for a bash32-floor scope/boundary card: none found.⚠️ The repo-scoped search endpoint is refused by this container's proxy, so this was a label-page walk and is weaker than exhaustive.
