check-side-effects-array cannot see a load-time effect written inside a const initializer, and scores @object-ui/types zero #8578

⭐ Decision batch #93 cites this finding by name. objectui#8344 comment 5585333656 refuses
the "narrowsideEffectsto the zod barrel" route on this card's measurement — verbatim:
"its detector cannot see aconst-initializer call — so A is not implementable as spelled
without weakening a gate." ⇒ the blindness recorded here is already load-bearing in a recorded
ruling, and it stays open independently of how any manifest question goes.Generated with Claude Code.

Container & model:M,mode:subagent,model: opus— tier is this seat's per-card judgement —dispatch-gates.mjs --tierderives families from the objectstack tree and asserts nothing about objectui paths (it says so itself: "no path-derived mandate … the tier stays the PM's per-card judgment call"), and objectui carries no copy of that script. Clause ② judged from card CONTENT.
Clause-②: no — a detector's classifier, internal tooling.⚠️ See the ruling interaction below: the card's own blindness is load-bearing in a recorded ruling, so widening the detector must ⛔ not be presented as re-opening it.

main✅,Fixes #8578✅, 2 files (+433/−5), 31 checks / 0 red / 10 pending at review time.⭐ It corrected the card twice, and I verified both against the tree
① The card's
--listquotation cannot be reproduced. It cites "0 module(s) with a top-level registration, 47 walked" for@object-ui/types— but that package declares"sideEffects": false, a boolean, not an array, so it is not in this gate's population at all. Firing control in the same run:@object-ui/app-shelland@object-ui/layoutboth carry arrays, and--listnames exactly those two. ⇒ the number the card was filed on is a reading the gate cannot produce for that package.② The zero has a second, independent cause the classifier fix does not touch.
evaluatePackagewalks only thesrc/index.*graph, andpackages/types/src/zod/index.zod.tsis not reachable frompackages/types/src/index.ts— 0 non-comment mentions ofzodin that barrel, with a firing control of 87 non-commentexportlines, so the zero is a property of the barrel and not of a grep that missed. ⇒ ⭐ the 47-walked zero survives this fix, and the dev filed that as objectui#8850 (bare, unassigned, unlabelled — correct for a defect) rather than quietly widening this PR to chase it.⇒ the card's mechanism holds — the classifier really could not see a
const-initializer effect — while two of its supporting statements did not. ⛔ That is the right way round, and it was found by measuring rather than by reading the card twice.The false-positive tail, which I asked for and which decides the shape
reading value files scanned 1,623 declarations newly classified as a registration 1 — packages/types/src/zod/index.zod.ts:438,export const AnyComponentSchema = defineNodeComponentUnion(…), the card's own true positive and the only one of 88 const-initializer call sites in that filemodules changing verdict 0 --listbefore vs afterbyte-identical (app-shell 14/449, layout 1/8), gate exit 0 both ways ⭐ And two coarser rules were priced and rejected with their numbers, ⛔ not dismissed:
- any call in a top-level initializer → app-shell 14 → 122 registering modules, 508 workspace-wide. Rejected because
new Set([...]),React.createContext(...),React.lazy(...)produce the binding's value and nothing else. - callee-writes without stopping at function boundaries → 1 false positive,
ConsoleShell.tsx:214, where thepending += 1write lives inside the closurewithSettleSignalreturns — so it happens per fetch, ⛔ not at load time. That case is now the suite's negative-direction test.
⇒ the boundary was chosen by measuring what each candidate rule costs, and both directions are pinned.
Ablation, including a failure it did not hide
Mutation: comment out the single new
classifyEffectbranch. On-disk proof by anchor count and blob hash; result 3 failed / 28 passed, with the negative-direction partners staying green — which is the correct signature. Restored byte-identical (git diff HEADempty, hash back tofa73bcb15).⚠️ ⭐ And the first attempt was reported rather than silently retried: its observation anchor usedgrep -cFon a substring the commented-out line still contains, so it announced "mutation did not reach disk" about a mutation that had in fact landed. ⇒ the same family as this seat's own errors today — a check whose subject it cannot actually distinguish. Anchor re-cut as a line-anchored regex and re-run.⭐⭐ The objectui#8344 interaction — flagged, ⛔ not resolved, exactly as dispatched
Decision batch #93 refused route A on "its detector cannot see a
const-initializer call — so A is not implementable as spelled without weakening a gate." The dev's finding:Both halves of that premise have moved: the detector CAN see the shape, and seeing it weakened no gate (0 verdict changes, measured). But re-pricing route A on that alone would be wrong, because objectui#8850 is a second obstacle the batch never priced: even with this fix, the enumeration for
@object-ui/typesis derived from a graph that does not contain the module the effect is in.⇒ ⭐ it moved a recorded ruling's premise and then argued against acting on that fact, because it found a second obstacle first. Nothing in this PR touches #8344, #8577, or any package's
sideEffectsfield — verified in the 2-file diff. Whoever holds objectui#8344 needs objectui#8850 before re-deciding, and this comment is the pointer.Declared narrowings, both with their evidence
Repo-wide
pnpm lintand the full 133-filescripts/__tests__sweep were not run:git grep -lnreturns exactly 3 test files naming the changed module, all green, and the module is imported by one other script whose suite is among the 3. The eslint verdict is invariant becauseeslint.config.jsconfigures noproject/projectService, so type-aware linting is off and this diff cannot move an untouched file's result. The card's Vite/rollup bundle measurement was not re-run — declared, with the reason that the classifier defect is provable statically and the manifest it bears on is objectui#8577's subject.⇒ Accepted.

This is the leg that matters — the whole case for the widening is that it costs 0 verdict changes, so a--listthat moved would mean the boundary drifted. - The negative-direction pin survives:
ConsoleShell.tsx:214'swithSettleSignal(...)is not classified as a registration, because its write lives inside the closure the call returns. ⛔ A suite with only positive cases would pass on the coarser rule that was rejected. - ⛔ No package's
sideEffectsfield moved — with a firing control: the same query must still find the arrays onapp-shellandlayout, or "unchanged" is a dead reading. objectui#8344 and objectui#8577 are untouched. - Nonsense control exits 1.
⚠️ ⭐ What this probe deliberately does NOT check, stated so nobody reads a green as more than it is: that@object-ui/typesnow scores non-zero. It does not, and it should not — objectui#8850 records the second, independent cause (the gate walks only the source barrel's graph, andzod/index.zod.tsis unreachable from it).

scripts/check-side-effects-array.mjsreports@object-ui/typesas having 0 modules with atop-level registration (its own
--listoutput: "0 module(s) with a top-level registration, 47walked"), while a bundler demonstrably drops a real load-time effect from that package.
Why the two disagree
The classifier sorts a module's top-level effects and counts a CALL STATEMENT. The effect it
misses is performed inside a
constINITIALIZER:defineNodeComponentUnionwrites the node recursion point's option slot as a side effect ofevaluating that initializer. To the classifier the module declares constants and does nothing; to
a bundler honouring
"sideEffects": falsethe const is droppable when its binding goes unread,and the write goes with it.
Measured
On this repo's own Vite/rollup lib build, an entry importing only
CardSchemafrom@object-ui/types/zodproduces a 370,652-byte bundle with the fill ABSENT, and a nested off-specnode is ACCEPTED — the pre-objectui#8344 accept set, silently. The same entry that also imports
AnyComponentSchemakeeps the fill and REFUSES the node. So the effect is real, it isload-time, and the gate that exists to enumerate exactly those effects scores the package zero.
Why this matters beyond one package
The gate's own file header states the design intent: an UNKNOWN effect must be an ERROR rather
than a quiet "not a registration", because "I did not recognise that" and "that is not a
registration" must not be the same answer. An effect inside an initializer currently takes the
second answer silently. Any package can acquire one the same way — a registry write, a cache
prime, a slot fill — and the gate will keep reporting zero.
@object-ui/typesmanifest to change; that decision is objectui#8577, and this classifier is wrong whichever way that decisiongoes.
Sketch of what a fix has to answer
constinitializer count as a registration? A bundler treatsit as droppable-with-the-binding rather than pure, so "it depends on whether the binding is
read" is a real answer the gate would have to model.
@object-ui/typesacquires a registering module and its manifest options changewith it — which is exactly the other card's decision, so the two want sequencing.
author does not read a zero as "this package has no load-time effects".
