The searchable-fields hints prescribe a "text/formula" mirror — the formula half never works, so the tool output now contradicts the docs that quote it

[os-zhuang]

Out-of-scope finding from #4840 / PR #6670 (measured by that dev, filed by the engine-core PM on its behalf — the cloud dev session could not file cross-surface issues). Recorded, not claimed.

Fact (origin/main, 2026-08-08)

Both authoring-time hints for a bad searchableFields entry prescribe mirroring the related value onto "a formula field" / "a text/formula field":

• packages/lint/src/validate-searchable-fields.ts (~:344-347 and ~:414, the searchable-field-unknown hint);
• the runtime dotted-path hint in packages/metadata-protocol/src/protocol.ts (~:4808-4813, assertSearchFieldsAreSearchable).

Only the stored half of that prescription works. A formula field is virtual — no driver materializes a column for it (packages/objectql/src/engine.ts:568-573; driver-sql/src/schema-drift.ts:337; driver-turso/src/remote-transport.ts:1224) — so a $contains predicate against it has nothing to scan; and CEL reads only record. roots of the record itself, so a formula cannot fetch a related title in the first place.

PR #6670's docs already say "stored field" and correct the hint inline where they quote it, which means the shipped corpus now deliberately contradicts the tool output it quotes — the remaining fix is the hint strings themselves (packages/**, out of scope for that docs-only PR).

Scope if promoted

XS: rewrite the two hint strings ("copy the value onto a stored text field"; drop the formula suggestion), plus their pinned message tests.

Adjacent (separate finding)

#6674: whether a virtual formula entry in searchableFields should be refused/warned at all — today it clears both lint and the #4254 gate and then silently never matches. This card is only the wording defect.

Refs: #4840, PR #6670 (measurement in its body and report), #4254, #6674.

[claude]

Findings-round grading: promoted — finding removed, pm:queue + domain:devx applied.

• Why promoted: the two authoring-time hints still prescribe a fix that can never work (mirror onto a formula field — virtual, no driver materializes it), and since PR docs(search): make the mirror field the one prescription for related-title search #6670 merged, the shipped docs corpus now deliberately contradicts the tool output it quotes. A real author hitting searchable-field-unknown today is handed a broken prescription. Scope is XS and decision-free: rewrite the hint strings to prescribe a stored text field, update their pinned message tests. Not target:v17 (internal authoring hint, docs already carry the correct prescription).
• Stale-premise check on origin/main @ e5bd768: packages/lint/src/validate-searchable-fields.ts:347 ("copy the value onto a formula field here") and :414 ("mirror it onto a text/formula") both live; the runtime hint has moved to packages/metadata-protocol/src/protocol.ts:4780 and now reads "a formula or rollup field" — still wrong, and doubly so: summary/rollup fields are likewise virtual per the copy-exclusion at protocol.ts:5941.
• Routing / cross-domain note: 2 of 3 hint strings live in packages/lint (domain:devx); the third is one string in packages/metadata-protocol (domain:metadata). Splitting a three-string rewording into two cards costs more than it protects, so this goes as a single dispatch under the cross-domain exception path: the claiming devx lane must declare the full file face in its claim comment, including protocol.ts:4780 and its pinned message test, and should check the metadata seat's hot-file serial queue for protocol.ts before claiming.
• Dedup: A virtual formula field declared in searchableFields clears lint and the #4254 gate, then silently matches nothing — the same fail-open shape #4254 closed one axis over #6674 (whether a virtual formula entry in searchableFields should be refused at all — domain:spec finding) confirmed open and distinct; this card is only the hint-wording defect. PR docs(search): make the mirror field the one prescription for related-title search #6670 (docs half) merged.

Claimed. Session session_01F8q5J1MQyocgtNspb15fSn, branch claude/issue-6673-searchable-fields-stored-hint, PR #6921 (draft).

Full file face (per the triage routing note): packages/lint/src/validate-searchable-fields.ts (:347, :414) + its pinned test packages/lint/src/validate-searchable-fields.test.ts; and packages/metadata-protocol/src/protocol.ts — read and re-verified, see correction below.

Cross-domain check: read the domain:metadata seat sticker (#6367) before touching protocol.ts. Current state: zero in-flight, and the maintainer's 2026-08-08 note explicitly authorizes non-overlapping-region parallel authors on that file. No collision.

Premise correction on the third target — protocol.ts:4780 does not say what this card (and the triage comment) describe. Verified against origin/main:

• assertSearchFieldsAreSearchable (protocol.ts:4978, the #4254 SEARCH-FIELDS gate this card is about) has no formula/rollup prescription in its dotted-path hint — it only says "'search' scans this object's own columns; a related record's column cannot be a search target." (protocol.ts:5056). git log -S "formula" -- packages/metadata-protocol/src/protocol.ts shows the string "formula" has never appeared in this function, in the file's entire git history.
• The text at :4780 ("a formula or rollup field that copies it into a real column") lives in a different function, assertSortFieldsExist (protocol.ts:4745) — the SORT axis (#4226/#4256), not searchableFields. It's the deliberate outcome #4256 (same filer, closed) asked for, and it's still consistent with its own current docs (content/docs/protocol/objectql/query-syntax.mdx:533-534 still says "formula or rollup"). No docs-vs-tool contradiction exists there today.
• Its pinned test is packages/objectql/src/query-expression-conformance.test.ts:455 — a third package, outside both this card named.

So PR #6921 fixes the two real packages/lint strings only (exactly as described, now pinned + reverse-verified) and leaves protocol.ts untouched. I've filed the SORT-axis question as its own out-of-scope finding rather than guess at it here (it's a plausible, structurally-identical defect, but it's a different function/axis/package and needs its own verification). Full report going to the dispatching PM.
