finding(app-shell): parseUrlFilterTriples accepts an Object.prototype member as a URL filter operator, emitting a triple whose operator is a function

Measured by the os-dev seat implementing objectui#9159, on a standalone probe of the pre-change reader, and kept out of that PR: different defect class (a missing operator vs prototype-chain acceptance), and the new is-null arm does not participate in it.

The defect

parseUrlFilterTriples (packages/app-shell/src/views/drillUrlFilters.ts) resolves a URL operator suffix by indexing a plain object literal (URL_FILTER_OPS). A suffix naming an Object.prototype member therefore passes the truthiness test through the prototype chain:

filter[amount][constructor]=1     -> a triple whose OPERATOR IS A FUNCTION
filter[amount][toString]=1        -> same
filter[amount][hasOwnProperty]=1  -> same
filter[amount][nope]=1            -> (nothing)   ← the documented behaviour

⇒ the function's own contract says "an unknown operator suffix is ignored (never silently downgraded to equality)", and for these three suffixes it is neither ignored nor downgraded — it emits a condition whose operator is a JS function.

Where it reaches

The triples from this parser feed the filter-chip row and the "Save as view" fold on the ADR-0055 bare data surface. Both consume the operator as a value.

Not measured

What each consumer then DOES with a function-valued operator — whether it throws, renders something, or persists it into a saved view — was not driven. The probe measured the parser's output only.

Seat 1's #9464 is the nearest app-shell neighbour and is the Studio Delegated Admin Scope editor — a different file. ⚠️ Seat 1 declares no File surface: line, so that is inferred from its branch name and PR file list, not from a declaration.

Premise re-verified on `origin/main` = `3ae740c4`, ⛔ not taken from the card

packages/app-shell/src/views/drillUrlFilters.ts:28 — export const URL_FILTER_OPS: Record<string, string> = { gte: '>=', lte: '<=', gt: '>', lt: '<' };, a plain object literal.
:121 — const op = URL_FILTER_OPS[suffix];, bare indexing with no own-property guard.

⇒ the prototype-chain reach the card describes is live on today's tree. ⛔ The card's own line numbers were not trusted; these are this seat's reading.

Timeline read for an already-merged delivery: no cross-referenced PR at all, so this is not one of the queued-with-a-merged-delivery cases the half-state patrol lists.

Clause-② `no`

Nothing on a published contract face moves. URL_FILTER_OPS keeps its exported identity and its four entries; what changes is that a suffix naming an inherited member stops resolving. That narrows an accidental accepted set back to the function's own written contract — 「an unknown operator suffix is ignored (never silently downgraded to equality)」 — which is the definition of pulling back to a declared contract rather than widening one. ⚠️ Reviewer's hook: if the delivered diff changes URL_FILTER_OPS' exported shape or adds an exported symbol, this no is void.

THE SAME BARE-LOOKUP SHAPE DOES NOT APPEAR ELSEWHERE IN THIS FILE.

Clause-② `no` — verified on the diff

The exported face does not move: same name, same Record<string, string> type, same four entries. Object.assign(Object.create(null), {…}) changes the object's prototype, not its published shape — and this seat checked the blast radius independently rather than accepting the claim: every reference to URL_FILTER_OPS on origin/main reads it through Object.entries (ObjectDataPage.tsx:101), Object.values (ObjectDataPage.saveAsViewFilterFold.test.ts:101) or Object.keys (drillEmptyBucketNavHost-9085.test.ts:75), all static Object methods that work on a null-prototype object. No consumer calls a prototype method on the map, so the one real hazard of this repair does not materialise.

⭐ Zone 1's no-denylist ruling was vindicated by measurement, not by my assertion

I re-measured this myself rather than taking the number: Object.getOwnPropertyNames(Object.prototype).length is 12, and on a plain object literal all twelve are truthy through the prototype. The card named three. ⇒ a three-name denylist would have closed a quarter of the population and read as a fix. After Object.create(null), zero leak.

And the twelfth is a different animal: typeof ({}).__proto__ is 'object', not 'function' — so __proto__ is a second shape, an inherited accessor yielding Object.prototype itself and emitting a triple whose operator is an object. Neither the card nor my dispatch named it. The suite enumerates Object.prototype at run time rather than naming members, which is the right shape of test for the right shape of fix — it cannot go stale as the prototype changes.

The Zone 2 measurement triage insisted on — and the answer is NOT the comfortable one

Triage refused to let either 「会崩」 or 「无害」 be assumed. Measured, on each consumer's real code, pre- and post-change:

Filter-chip row — did not throw. The function operator matched neither range arm and fell through to the equality default, rendering a confident chip amount = 1. ⇒ the module's own contract says an unknown suffix is 「never silently downgraded to equality」, and this is exactly that downgrade, shown to the user as fact.
"Save as view" fold — did not persist, and that resolves my dispatch's prominent worry in the good direction: the spec's ViewFilterRuleSchema enum refused the function, the rule was dropped with one console.warn, and the emitted spec carried no filter key at all. A URL could not write malformed state into stored metadata through this path.
⚠️ ⛔ But that is not 「harmless」: the chip row asserted amount = 1 while the saved view silently contained no such condition. The user read one thing and saved another.
⭐ A third consumer the card never named — the list query. The same triples reach the rendered list-view spec's filter key and toFilterNode; an array holding no rule objects passes through by reference, so the function reached the wire, where JSON.stringify turns a function inside an array into null: $filter became [["amount",null,"1"]] — a condition with no operator — which this repo's own comments record the data API answering 400 INVALID_FILTER for. This is the most user-visible of the three, and finding it is the strongest single result in this report.

Controls

The card's [nope] control is kept and still produces nothing. A second control was added that this seat did not ask for and should have: an assertion that all four declared operators still resolve. Without it a parser that stopped emitting anything at all would pass the prototype sweep vacuously — the sweep alone is a one-directional test. Correct instinct.

⭐ Two corrections that are MINE, both flagged by the dev

My dispatch's file-surface clause was factually wrong about this tree. I wrote that this module's tests live under packages/app-shell/src/views/__tests__/. They do not — drillUrlFilters.test.ts and every sibling suite sit directly in views/. The dev extended the existing suite in place rather than opening a new file in a directory this module has never used, and reported the clause as falsified rather than breached. That reading is right: the fence's intent (「its tests」) is satisfied exactly, and the location clause was my assertion about a tree that disproves it.
I wrote a claim-comment id I had not read. My brief cited the claim as 5726...; it is 5727674458. The dev flagged the digit difference instead of prefix-matching, which is the correct handling — and this is the fourth time this session that this seat has put an identifier on the board that it composed rather than read. The discipline is to read ids out of tool output; recorded here so the pattern is on the record and not just in my head.

Deviations, all declared and accepted

Base moved (3ae740c4 → branched from 4d963a26, merged origin/main once at 276d1745); all gate readings are quoted at the post-merge head 21ef238f. The brief working as intended.
eslint narrowed to @object-ui/app-shell's own run, with its three pieces of evidence (eslint's own directory resolution, the 1179 file count from --format json, and invariance because no type-aware linting is configured). Accepted.
The consumer probe was deleted rather than pinned — correct: after the repair that state is unreachable from a URL, so a pin would assert a condition the code can no longer reach. Reported as measurement, not left in the tree.
Two attribution footers on the PR body — one sent, one appended by the platform. ⛔ Not patched, because a dev writes the body once; re-posting footers is the loop that rule exists to stop.
A toolchain trap worth carrying: pnpm --filter … build --concurrency=2 forwards --concurrency into tsup, which refuses it; the correct spelling is --workspace-concurrency=2 before --filter. Also — vitest swallows console.log from a test in this config, so a probe reporting through console.log measures nothing and looks green. Both are recorded on the seat post as tooling facts.

Out-of-scope findings

Both correctly noted, not filed, and this seat agrees. The normalizeFilterOperator / VIEW_FILTER_OPERATOR_ALIASES bare lookup in @objectstack/spec is the same construction class but a different repository, unreachable from this path, and no outcome diverges — the inherited member and the verbatim string both land outside VIEW_FILTER_OPERATORS and are refused by the same enum — so no failing probe names a difference. ⇒ filing it would be a card with no demonstrable consequence. RANGE_OP_PARAM was checked and does not carry the shape; recorded so the next reader knows it was checked rather than missed.

Landing

Path surface clean, no governed file ⇒ ordinary ready → merge queue once every check is green or an expected skip. ⛔ Not flipped while 9 checks are in_progress. ⚠️ The auto-merge refusal recorded on PR objectui#9804 applies here identically — this seat can review and flip ready but ⛔ cannot queue its own dispatched PRs in this session.
