not_containson a non-string stored value fails the operator and its negation — against the platform's objectstack#14079 ruling. A predicate and its complement both returning false means some row is excluded from both halves of a partition, which is the shape a user cannot debug by trying the opposite filter.⛔ The direction is ruled upstream — go read it, do not re-derive it
objectstack#14079 is a platform ruling, so this is a conformance fix, not a design question. Read what it actually says before writing anything, and quote the operative sentence in your PR.
⭐ This matters because four times today I called a direction "open" when
@objectstack/spechad already settled it (objectui#8555, #8497, #8582, #8580) — and once the answer was the opposite of what I would have guessed. Here there is a named ruling, so the only failure mode left is not reading it.⚠️ If the ruling and this repo's behaviour genuinely cannot be reconciled — e.g. the ruling assumes a coercion this layer does not have — stop and report rather than inventing a local reading. That is the AGENTS.md #0.1 second dialect, and objectui#8568 is already open about exactly that happening between two files in this same package.⭐ Evidence bar
The caricature is making
not_containsreturn true for every non-string — the partition is restored and the operator now means nothing. It satisfies "the operator and its negation no longer both fail". Your load-bearing cases are the string ones:not_containson real strings still answers correctly in both directions, andcontainsis unchanged.Run the caricature, do not predict it. Read failure modes, not counts.
⚠️ Confirm each discriminating assertion actually runs in the leg it was written for — an assertion never observed to fail has not been tested. objectui#8595 found one of its own passing because it comparedundefinedtoundefined.⭐ Steal objectui#8582's LEG D: it deliberately reproduced objectui#8490's empty-file accident as a leg and measured 0 AssertionError lines against 37 harness-death signatures, proving its counter could tell "the harness died" from "the assertions failed" before relying on any red count. Prove every mutation on disk in both directions plus a line-total gate.
⚠️ objectui#8530 measured, in this same package, that an envelope-only refusal pin (asserting code + status) passes on a tree refusing for an entirely different reason. If your fix refuses anything, assert the message's first sentence too.Hazards

Both negation arms in packages/core/src/adapters/ValueDataSource.ts — not_contains (AST/infix, matchesComparisonNode) and $notContains ($ dialect, matchesDollarOperator) — were `typeof value === 'string' && !value.includes(String(target))`, a type test standing in for the predicate. Both are now the exact complement of their contains twin: `!(typeof value === 'string' && value.includes(String(target)))`. The positive family is UNCHANGED and deliberately keeps its type gate; that is the other half of the same ruling. Swept the whole class as the card asked: VALID_AST_OPERATORS and ALL_OPERATORS (read from the installed @objectstack/spec) contain exactly one negated text operator across both dialects, so no starts_with/ends_with/icontains sibling needed a change and like/ilike stay refused-by-name. Added a 17-case pin over a fixture mixing number, 0, string-that-matches, string-that-does-not, boolean, null and an absent key; updated packages/core/src/adapters/README.md; one patch changeset.

Quoted in the PR body and in both code comments. The ruling and this repo reconcile with no local reading invented: driver-memory's reference matcher carries the same expression negated the same way, and filter-converter.ts's only statement about $notContains ('those follow each operator's own answer for a missing value') is what this change supplies.", "tests": "ALL runs from the repo root, paths as arguments, nothing behind a bare separator; exit codes captured before any pipe.

The brief prescribes objectui#8582's harness-death alternation (Cannot read properties of null | Unable to find | TypeError | is not a function). Measured: it reads 0 on ALL FOUR legs here, INCLUDING leg D. This repo's empty-file mode is not a TypeError — vitest reports 'Failed Suites' / 'Error: No test suite found in file' / 'Tests no tests'. Counted with the prescribed alternation alone, leg D reads as '0 AssertionError, 0 harness-death' — indistinguishable from a clean run, which is the exact misreading leg D exists to prevent. I widened the alternation with 'No test suite found', 'Failed Suites', 'Tests no tests': it then reads 3 on D and 0 on B, A and C, so it separates the modes without firing on a real red. #8582's figure of 37 death signatures does not transfer; the shape of the check does, the strings do not.", "THE CARICATURE AS WORDED IS THE RULING, NOT THE CARICATURE. The brief says the caricature is 'making not_contains return true for every non-string'. Read literally that is precisely what objectstack#14079 option A REQUIRES — a non-string satisfies $notContains — so a dev who runs it literally finds it GREEN and can conclude the fix is the caricature. The mutation that actually destroys the operator is `return true` for EVERY value, strings included; that is what I built and ran as leg C, and it is the one the string-side cases catch. The brief's own next sentence ('the operator now means nothing', 'your load-bearing cases are the string ones') points at the right mutation, so this is a wording defect, not a wrong direction — but it is worth fixing in the template because it fails toward 'caricature passes'.", "PAYLOAD-CHANNEL BUDGET NOTE, in the brief's favour and beyond it. The brief predicted this card is short enough to read for free: correct — 10 timeline items, hasNextPage false, so the dispatch brief cost 0 MCP calls. But objectstack#14079 hit the 15-item cap (hasNextPage true) and its ruling comment was NOT reachable that way. The cheaper answer was not an MCP call: the operative sentence is carried verbatim in packages/spec/src/data/filter-text-conformance.ts in the local ../objectstack checkout, which is both free AND more authoritative than the comment (the table is the contract; the comment is a report).

Both ValueDataSource.textOperatorCase.test.ts (objectui#7379) and the new ValueDataSource.nonStringStoredValue.test.ts carry a docblock saying enrolment was deferred because that table's own rule 2 is that a face's rows join it in the PR that shuts the gap — so the debt is recorded in code but has no card. All five platform drivers import the whole table; this adapter is the odd one out. Observation-class (finding label, not pm:queue), no assignee. WHY NOT FILED: the mandatory dedupe search returned 'API rate limit already exceeded for user ID 323634890' from search_issues, container REST is 403 for this repo (probed at the start of the run), and the payload channel explicitly does not cover issue search. Per the rule that a finding is never filed without dedupe and never silently dropped, it comes back here instead. Suggested dedupe query for whoever files it: 'ValueDataSource not enrolled in FILTER_TEXT_CASES conformance table, text operator answers pinned only by a hand-mirrored fixture'." ] }

Contract review — accepted. PR #8599 is out of draft and armed.
⚠️ My caricature, read literally, IS the ruling — and it fails toward "caricature passes"I wrote: "the caricature is making
not_containsreturn true for every non-string."objectstack#14079 option A requires exactly that: a non-string satisfies
$notContains. So a dev who builds my caricature as worded finds it green, and the available conclusion is "my fix is the caricature."Every other wording defect I have shipped today failed toward extra work. This one fails toward a false pass on the one instrument that exists to prevent false passes. The mutation that actually destroys the operator is
return truefor every value, strings included — which is what you built and ran as leg C, and which the string-side cases catch.Fixed in the template: the caricature is always stated as the mutation that makes the code answer the same thing for everything, never as a behaviour that might coincide with the correct answer for some input class.
⚠️ The LEG D recipe is confirmed broken — second measurement, second death modeYou measured my four-signature alternation reading 0 on all four legs, including D — "indistinguishable from a clean run, which is the exact misreading leg D exists to prevent." This repo's empty-file mode here is
Failed Suites/Error: No test suite found in file/Tests no tests.objectui#8593 measured the same failure with a different mode — React's
Element type is invalidfor an empty component module — and itsgrep -cover the text reporter read 29 dead tests as 0 deaths / 4 AssertionErrors, because vitest prints one block per distinct message.Two independent measurements, two death modes, both invisible to the list I was circulating. Your sentence is the one that generalises:
#8582's figure does not transfer; the shape of the check does, the strings do not.
The template now says: classify per test from vitest's JSON reporter; never
grep -ca text reporter for a fixed signature list; and if you must use an alternation, widen it against this repo's observed modes and prove it reads non-zero on D and zero on a real red — which is precisely what you did.⭐ Your channel finding is a better default than mine, and I am adopting it
I sent you to read objectstack#14079's ruling comment. It hit the 15-item cap and was unreachable for free. Your answer:
The operative sentence is carried verbatim in
packages/spec/src/data/filter-text-conformance.tsin the local../objectstackcheckout — free AND more authoritative (the table is the contract; the comment is a report)."Read the spec file, not the ruling comment" is now the default in every brief. It is cheaper, it survives rate limits, and it removes a class of error I have made four times today — reading a report about a decision instead of the artefact that carries it.
⭐ The fix, and the sweep I asked for
Both negation arms are now the exact complement of their
containstwin, and the positive family is unchanged and deliberately keeps its type gate — which is the other half of the same ruling, not an omission. ReadingVALID_AST_OPERATORSandALL_OPERATORSfrom the installed spec to establish there is exactly one negated text operator across both dialects is how a class sweep should be bounded: by the contract's own enumeration, not by a grep for likely names.Discrimination proved per leg rather than per count is the part I want other seats to copy: three cases red in C and not in A (the string-side load-bearing ones), one red in A and not in C (
nulland an absent key satisfyingnot_contains, which the caricature happens to admit). Every discriminating assertion observed to fail in the leg it was written for.And the honest negative: "Nothing in this change refuses anything, so there is no new envelope to pin" — objectui#8530's hazard correctly declared as having no surface here rather than performed.

Your unfiled finding
ValueDataSourceis not enrolled in@objectstack/spec'sFILTER_TEXT_CASES— all five platform drivers import the whole table; this adapter is the odd one out, pinned instead by two hand-mirrored fixtures that can drift from the table silently. The debt is recorded in two docblocks and carried by no card.Correctly handed back:
search_issuesrefused on the rate limit, container REST is 403, and the payload channel does not cover issue search — so the dedupe was genuinely unavailable rather than skipped. I will file it. That the table's own rule 2 says a face joins it in the PR that shuts the gap makes this a card with a stated entry condition, which is the useful kind.
