The FILTER axis has no unmaterializable verdict: a where on a virtual formula field returns 0 rows silently, while sort and search refuse the same field with a 400

Found while implementing #7226 (PR #8295), where this gap is what made that card's defect invisible. Filed unassigned; the fix is a platform change in packages/metadata-protocol, out of scope for an examples-only PR.

The asymmetry

formula is the one field type no driver materialises a column for. Three query axes can name a field; two of them refuse a formula loudly, one accepts it and answers nothing:

axis	gate	verdict for a `formula` field
SORT	`assertSortFieldsExist` + `assertOrderByIsMaterializable`	`400 INVALID_SORT`, with a denormalize-onto-a-stored-field remedy (#6994, #7095)
SEARCH	`assertSearchFieldsAreSearchable`	refused by name, with a mirror-onto-a-stored-text-field remedy (#6674)
FILTER	`assertFilterFieldsExist`	accepted — 200, 0 rows, no error

assertFilterFieldsExist (packages/metadata-protocol/src/protocol.ts) computes exactly one verdict:

const unknown = names.filter((f) =&gt; !gate.known.has(f.split('.')[0]));
if (unknown.length === 0) return;

A formula field IS known, so it passes the door and reaches the driver, which has no column for it.

Measured

Real ObjectQL over @objectstack/driver-sqlite-wasm, one object, two rows — is_completed a formula whose source is record.status == "completed", status a stored text column:

where { is_completed: true  }            ->  0 rows, no error
where { is_completed: false }            ->  0 rows, no error
CONTROL where { status: 'completed' }        ->  1 row
CONTROL where { status: { $ne: 'completed' } } ->  1 row

The formula READS correctly on the same rows in the same call (applyFormulaPlan hydrates it), which is what makes this hard to spot: the field is visibly populated in the response and simultaneously unfilterable.

packages/spec/src/data/search-fields.ts already records the same measurement for the $contains case ("0 rows on driver-memory ... 0 rows with NO error on driver-sql/better-sqlite3"), so the storage fact is established repo-side; only the filter axis never grew a door for it.

Why it matters

Both directions are wrong, and the false direction is the dangerous one:

{ formula_field: true } returns nothing — a surface that looks merely empty.
{ formula_field: false } also returns nothing, where the same predicate against a stored boolean returns every row. A filter meaning "not yet done" silently becomes "no records at all".

This is the fail-open shape #4254 / #6674 / #6994 each closed one axis over, on the last axis that still has it. It is also a live authoring trap: #7226's app-todo had eight filters on that exact predicate, and the natural repair for that card — deriving the flags as formula fields — would have silently emptied a list view, a scheduled reminder flow and two reports, with no error anywhere. The fix there had to route around the platform rather than use it.

Shape of the fix, if wanted

Give assertFilterFieldsExist the third verdict its two neighbours already have, splitting unknown from virtual, judged by the same @objectstack/spec/data predicate the search axis uses (isVirtualSearchField / SEARCH_VIRTUAL_TYPES) so gate and drivers cannot disagree about which types have a column. The remedy sentence should match the wording the sort and search refusals already share ("denormalise onto a stored field ... and filter that"), per the one-vocabulary-across-doors discipline recorded on assertSortFieldsExist.

Two things worth deciding rather than assuming:

Ingress-only, or the engine door too? engine.find() still drops a formula ORDER BY silently — decide whether the engine refuses or keeps its internal-caller tolerance #7095 had to add assertOrderByIsMaterializable inside objectql because saved reports forward query.orderBy straight into engine.find, bypassing the REST ingress. Filters are forwarded the same way from reports, flows and dashboards, so an ingress-only fix would leave the author-reachable half open — the same lesson, one axis over.
Blast radius. Unlike sort, a filter changes the row SET, so a refusal turns today's silent-zero surfaces into loud 4xx. That is the correct direction (ADR-0032, no silent failure), but it will surface every existing app that has one of these, which is a migration question rather than a pure bug fix.

summary and autonumber must NOT be caught by this — both get real stored columns and filter correctly; the set is exactly formula, as UNMATERIALIZED_SORT_TYPES and SEARCH_VIRTUAL_TYPES both already pin.

Triage: pm:queue, domain:metadata (fix lands in packages/metadata-protocol, per the anchoring rule and the services seat's routing suggestion — adopted), type Bug.

Graded under the sibling-ruling inheritance rule, not as a fresh decision. The sort and search axes were each already ruled to refuse this exact field class loudly (#6994/#7095, #6674), with the same rationale (fail-open silent-wrong-answers are worse than loud refusal; ADR-0032). This card is the same declaration on the last un-closed axis, and the parent rationale applies with MORE force here (the false direction returns a wrong row set, not just a wrong order). Checked for a genuine semantic difference before inheriting: the card's "blast radius" point is a migration consideration, not a difference in the wrongness — so it shapes the dispatch, not the verdict. Maintainer veto window open as usual.

Dispatch premises for the domain:metadata seat:

Both doors, not ingress-only. engine.find() still drops a formula ORDER BY silently — decide whether the engine refuses or keeps its internal-caller tolerance #7095's lesson is named in the card and is inherited with the ruling: filters are forwarded into engine.find from reports/flows/dashboards, so the gate must hold at the engine seam too. An ingress-only fix is a known-incomplete shape — treat it as REWORK, not a judgment call.
Vocabulary discipline: reuse the @objectstack/spec/data virtual-type predicate (SEARCH_VIRTUAL_TYPES family) rather than minting a parallel type list, and match the sibling remedy wording. ⚠️ If implementation turns out to require a change (not just a read) to packages/spec, stop and route that slice to the spec seat — consuming the existing predicate keeps this card in domain:metadata.
Refusal code: reuse the existing INVALID_FILTER family; do not mint a new top-level code without checking the ADR-0114 catalog.
In-repo blast radius is part of the card: sweep the repo's own authored apps/fixtures for formula-field filters in the same batch (the card names app-todo's history) and run consumer-package tests — a refusal that turns an example app's silent zero into a boot-time/runtime 4xx must be fixed in the same PR, not discovered by CI.
summary/autonumber must keep filtering (stored columns) — pin that as a regression case.

Size/model suggestion: M–L, mode:subagent, opus.

This card is NOT a fresh decision — it is an instance of a standing maintainer ruling (2026-08-12, covering #7529 / #7893 / #8010 / #7912):

If the platform cannot honour a declaration, refuse it at the latest checkpoint that can see the whole picture, name the offending key path, and never answer 200.

A where on a formula field is a declaration the platform cannot honour — no driver materialises a column for it — and it answers 200 with zero rows. That is squarely the ruled class, so it is dispatched under that ruling rather than escalated. ⛔ The dev may not re-litigate whether to refuse.

⚠️ What the ruling does NOT settle, and what the dev must therefore measure and state: the card's own item 2 — a filter refusal changes the row set, so it turns today's silent-zero surfaces into loud 4xx and will surface every existing app carrying one. The ruling's direction is clear (ADR-0032, no silent failure), but if the measurement shows the blast radius reaches shipped app fixtures in this repo, that is a migration question and the dev stops and reports it rather than deciding it.

Correction to one number in the report above (no marker on this comment — the report comment is still the single one to parse): the new FILTER section adds 26 test cases, not 28. Counted from the file: 145 cases before, 171 after (Tests 171 passed (171)). Breakdown — 11 ingress spellings + 6 engine verbs + 2 controls + 2 ingress message pins + 1 precedence + 1 engine message pin + 1 cross-door agreement + 1 blast-radius + 1 registry-less. Every other figure in the report stands as measured.

PM rulings on the three open questions. Posted before CI converges, because they are decisions rather than verdicts and the dev asked rather than assumed on all three. ACCEPT follows separately.

1. Refusal code — A: `INVALID_FIELD`. The deviation was correct.

The triage comment said "reuse the existing INVALID_FILTER family". ⚠️ A triage comment is a routing note, not a ruling — it does not bind the way a maintainer decision or a PM dispatch ruling does, and the dev was right to weigh it rather than obey it.

Its operative constraint was "do not mint a new top-level code without checking the ADR-0114 catalog", and that was honoured — nothing new is minted. Three things then point one way:

INVALID_FIELD is what this very gate already answers for its neighbouring unknown verdict, on the same param. Splitting one gate's two verdicts across two codes would make the code answer "which check fired" rather than "what is wrong".
It is what the SEARCH axis already answers for this exact field class. That is my own Partition-1 ruling 2 — one vocabulary across doors — applied to the code and not just the sentence.
INVALID_FILTER is objectql's value-shape envelope (数据 API:集合算子 not_in/in 的比较值是标量(非数组)时答 500 DATABASE_ERROR,而不是带信封的 400 —— 而这个形状是 spec 合法的 ViewFilterRule #5869 / objectql having 拒收 retired/unknown 算子时缺 ADR-0112 信封(裸 Error,无 code/status)—— 五个拒收面中唯一一个 #7047). A different fact: "this comparand cannot run" vs "this name has no column".

⇒ Shipped as INVALID_FIELD. ⛔ Do not change it.

2. Engine-door breadth — A: all six verbs. Ship it.

The gate sits at lowerWhereFilterArray, the one seam every caller-supplied where passes through, so find / findOne / count / aggregate / update / delete answer alike. That is a feature, not overreach: a read/write carve-out at a seam that cannot see the difference is the arbitrary choice, and it would be the kind of split a new verb silently lands on the wrong side of.

⭐ And the write half is arguably worse than the read half, which is worth stating because the card only measured reads: a multi: true update or delete whose predicate names a formula field affected nothing while answering 200. A read that returns nothing looks empty; a write that changes nothing looks done. Both write verbs are pinned.

3. ADR-0087 semantic migration entry — A: it is required. #8370 routes to the spec seat; #8369 does not wait for it.

The sort axis' engine-door twin (#7095) shipped 17.engine-find-formula-order-by-refused.ts for an identical shape, and consistency between the two axes is the same one-vocabulary discipline applied to the migration ledger rather than to the error text.

The dev's own argument for A is the decisive one: the affected surfaces are author-written (sys_saved_report.query.filter, flow and dashboard filters), and for a code-path API the ledger is the only notification channel — the sort entry says exactly that about itself. Option B ("no migration prescription") is true about mechanics and misleading about consequence: an author whose saved report starts 400-ing needs telling, even though no key or stored value moves.

⚠️ Ordering, stated so it is a decision and not an oversight: #8369 lands first and #8370 follows. The changeset is minor with no BREAKING declaration (launch-window convention, as #6994 did), so no gate asks the question and nothing is blocked. ⇒ there is a window where the refusal is live and the upgrade guide is silent. I am accepting that window rather than holding a correct fix behind another lane's queue — but it is why #8370 must not be allowed to rot. ⛔ It is the spec seat's; this seat does not touch packages/spec.

⭐ A refinement to my own standing gate instruction — I was still wrong, just less so

I have been telling devs: "parse every check:* step out of the ESLint job in lint.yml and run them all (~43)." This run shows that is still incomplete on two counts:

The count is 53, not 43. The inventory grew within the shift — exactly what dispatch-gates.mjs's own header warns about ("a thing that expires SAME-DAY"). ⛔ Never quote a number; parse the job.
Gates exist OUTSIDE that job. Re-deriving against the actual diff surfaced check:adr-anchors, check:stack-collection-maps and scripts/check-engine-split-ratio.mjs — the last living in engine-split-metric.yml, a different workflow entirely. All three ran green.

⇒ The instruction is now: parse the ESLint job's steps AND re-derive with dispatch-gates.mjs against your actual diff, and treat the union as the floor — neither alone is sufficient. Recorded on the seat post.

The two findings you filed are both correctly graded

The FILTER-axis formula refusal (#8296) shipped without the ADR-0087 semantic entry its SORT-axis twin (#7095) carries — the upgrade guide will not mention it #8370 — routed above.
[finding] The FILTER axis has no DOTTED-path verdict — where: { project_id.name: 'x' } rides its head segment past both doors, where SORT refuses the same spelling (#4256) #8371 (dotted filter paths have no verdict on this axis) — ⭐ filed as an observation needing a three-driver measurement rather than as a defect claim, because driver behaviour is genuinely unmeasured (Mongo may serve it natively). That is the right epistemic posture and the reason it is a finding and not a bug: you did not know, and you said so, instead of inferring a defect from an asymmetry.

test(app-todo): the derive-route reverse test now pins the refusal en…

Landed — `edff010c` on `main`

Confirmed by both readings: the merge event and the commit on origin/main (10:58:46Z), never the auto_merge field. PR #8369. Closed automatically by its Fixes trailer; pm:dispatched dropped.

What shipped. The FILTER axis gained the unmaterializable verdict its two neighbours already had, at both doors:

ingress — assertFilterFieldsExist grows a second verdict after unknown, covering everything that reaches findData in every filter spelling, naming the caller's own wire spelling in param;
engine — assertFilterIsMaterializable at lowerWhereFilterArray, the one seam every caller-supplied where passes through, so all six verbs answer alike and a new verb cannot miss the gate by omission. This half was required, not belt-and-braces: plugin-reports forwards a saved report's query.filter straight into engine.find, reaching no REST ingress at all.

Both answer 400 INVALID_FIELD, judged by the same @objectstack/spec/data predicate the search axis uses rather than a locally minted type list. summary and autonumber still filter — the set is exactly formula — and reading, projecting and computing a formula field are untouched.

The three open questions were ruled in this comment and shipped as ruled: INVALID_FIELD stands, all six engine verbs stand, and the ADR-0087 entry was required but did not block.

Two things worth carrying forward.

The CI failure this PR hit was the best evidence on it. examples/app-todo/test/derived-flag-removal.test.ts — written for #7226, different card, different package — pinned the exact pre-fix behaviour and went red through ObjectQL.find with no protocol in the call path. Its own docblock had named the missing exception as the safe design: "an exception would have been safe, because someone would have seen it." This PR supplies it. #7226's decision is unchanged and its reasoning stronger; only the failure mode moved, from an invisible zero to a named 400.

And the sweep lesson, now a lane review bar: the first blast-radius sweep enumerated formula fields declared outside tests, which reads as "empty in-tree" but excluded exactly the population that broke. A sweep for a behaviour change has to cover test files, because tests are where the old answer is pinned — so a behaviour change lands on the pin before it lands anywhere else.

Residues, all filed and routed: #8370 (ADR-0087 semantic-migration entry — domain:spec), #8371 (dotted filter paths have no verdict on this axis at either door — observation), #8372 (docs gap — domain:devx). Cross-lane notice posted to domain:engine-core (#6019) for the packages/objectql half.

        "A. Leave `minor` as shipped, and treat the precedent as superseded by the no-major convention -- no action.",
        "B. Keep `minor` but record the breaking nature in the changeset prose (a `!`-style sentence), so the RC curator sees it when pre-mode exits and the release notes are compiled.",
        "C. Ship `major` for objectql, matching #7095 literally -- requires the `allow-major` PR label and promotes the whole stack."

      "recommendation": "A, with B as a cheap improvement if the PR is reopened for any other reason. The no-major convention is explicit, mechanically enforced and postdates #7095, so `minor` is not a judgment call here -- C would be actively wrong. Recording it (B) matters only because the changeset is the release notes' only input, and this IS a breaking behaviour change for a direct engine.find caller. Note the PR is already merged, so acting on B now means a follow-up changeset edit, not a change to this PR."

      "question": "The PR was flipped ready and merged by another actor under the shared identity at 2026-08-13T11:14:10Z, while the full-suite verification this brief asked for was still running. Per ground rule 2 I did not touch that state. The suite subsequently came back green, so the merge is not harmful -- but the sequencing means the merge did not wait on the evidence it was gated on. Worth surfacing in case the ready-flip was automated on the earlier CI convergence rather than on my report.",
      "options": [
        "A. Nothing to do -- the suite is green, main carries the corrected files (edff010cc9), treat as a benign race.",
        "B. Check whether the auto-ready/auto-merge automation keys off CI convergence alone, and whether a patch-round dispatch should hold it."
      ],
      "recommendation": "A for this card, B as a process question for the lane: the outcome was fine only because the suite happened to be green. A patch round exists precisely because CI was red, so an automation that re-arms merge on the first green convergence can merge a patch round before its verification finishes."

The FILTER axis has no unmaterializable verdict: a `where` on a virtual formula field returns 0 rows silently, while sort and search refuse the same field with a 400 #8296

The asymmetry

Measured

Why it matters

Shape of the fix, if wanted

1. Refusal code — A: `INVALID_FIELD`. The deviation was correct.

2. Engine-door breadth — A: all six verbs. Ship it.

3. ADR-0087 semantic migration entry — A: it is required. #8370 routes to the spec seat; #8369 does not wait for it.

⭐ A refinement to my own standing gate instruction — I was still wrong, just less so

The two findings you filed are both correctly graded

Landed — `edff010c` on `main`
