A formula field that reads through a reference (record.book.title) passes validateExpression, then reads null on every row: the read path projects only the row's own columns

Ruled: 6245544505 · letter A on objectstack-ai/cloud#2925 (batch #362 item 4) · direction (a) · 2026-10-18T04:15Z
The formula read path preloads one hop of the referenced fields a formula names (page-batched, as validation rules do); lint admits one hop and refuses two; a title formula over lookups sorts and searches by its stored value or is declared unsortable — written as an ADR-0079 note. p1 target:v18 stands. pm:blocked → pm:queue in this act.

Source

Read on the framework pin cloud consumes (.objectstack-sha be076dad28a0, frozen tree), while the repo:cloud#2 seat checked the premise of objectstack-ai/cloud#2925 before dispatch. That card asks the AI builder to point a junction object's nameField at a formula composed from its two lookups' titles (「{图书} · {读者} · {借出日期}」). ADR-0079 D3 prescribes a text formula as the composite-title mechanism. Nothing tells an author that such a formula cannot read the other side.

What happens

Authoring accepts it. @objectstack/formula's validateExpression('value', "record.book.title + ' · ' + record.reader.name", { objectName: 'loan', fields, fieldTypes: { book: 'lookup', reader: 'lookup', … }, scope: 'record' }) answers 0 errors and 0 warnings at the pin. This was measured by a probe against the pin's packages/formula/dist.
- The lint's formula pass (packages/lint/src/validate-expressions.ts, judgeFieldFormula, about line 2720) calls it with no traversalHydration.
- The A field-level requiredWhen / readonlyWhen that reads through a lookup (record.account.tier) is accepted at authoring, but the runtime never hydrates it, so since ADR-0137 D2 every write that reaches it is refused #20078 refusal of a read through a reference covers FieldTraversalSlot = 'requiredWhen' | 'readonlyWhen' | 'option visibleWhen' only (line 1190). A field expression is not in it.
The read path cannot honour it.
- planFormulaProjection (packages/objectql/src/engine.ts, about line 1690) projects this object's own stored columns for a formula. A reference column holds an id, so record.book.title meets a string.
- Only the validation-rule path pins one hop before evaluating (packages/objectql/src/validation/rule-validator.ts with analyzeRelationshipTraversals).
- The read writes null for the field and reports the fault to the sink (engine.ts, about line 2603, formula: the metadata save door stores a formula that calls an unregistered function (sqrt), and every read answers null with nothing logged — the docs say the shared validator backs metadata registration #22019). That happens on every row.
Consequence for a title: a formula nameField written this way shows no title on any record. An AI that follows ADR-0079 D3 literally for a junction object (a loan, a booking, an enrolment) produces it.

Declared ≠ enforced

The expression is accepted where it is declared and never honoured where it runs. This is the same shape #20078 closed for field-level predicates. Which direction closes it is the open question on objectstack-ai/cloud#2925 (its decision analysis follows on that card):

(a) the formula read path pins one hop the way validation rules do, so the expression works;
(b) the formula pass refuses a read through a reference loudly, with the prescription that names the alternative.

Either way, today's silent null goes.

Reach

Any formula field (not only a nameField) whose expression names record.<lookup>.<field>. The AI builder in cloud is a producer: its prompt tells the model to compose titles as formulas (blueprint-tools.ts, the nameField rule).

Dedupe

Read: #20078 (the predicate slots, closed), #22019 (unregistered function → null, closed), #20082 (can() in a formula, closed), #6674 (formula in searchableFields, closed). None covers a formula expression read through a reference.

_{Filed by the repo:cloud#2 seat (seat post #24145, session session_01Cbdek8SKSHxddGqTPZXdqX). ⛔ Not a claim.}

Reach, one more producer, read at the same pin (be076dad28a0) · repo:cloud#2 · session session_01Cbdek8SKSHxddGqTPZXdqX · 2026-10-17T17:04Z

The spec's own AI blueprint schema teaches the composed title with a reference in it:

packages/spec/src/ai/solution-blueprint.zod.ts:95 (BlueprintFieldSchema.expression) and StrictField.expression (about line 327) give the example "record.order_no + ' · ' + record.customer" "for a composed title".
:107 / :338 (nameField) recommend "{order_no} · {customer}".

customer there is a lookup. The bare spelling reads the stored id, so the title carries a raw key. The traversal spelling (record.customer.name) reads null, as this card's body states. Neither gives the customer's name. Whichever direction this card takes, these describe strings are model-facing and should change with it. Not measured: what a model actually emits from them.

Triage: p1 · `target:v18` · `domain:engine` · `pm:blocked` on the maintainer's ruling on cloud#2925 · triage seat · `session_01AavokzJ5DndAwitDXvKy4U` · 2026-10-17T17:58Z

Triage seat (objectstack-wide, seat post #6015). ⛔ Not a claim, ⛔ not a dispatch.

Fresh read on origin/main f963d8e2b3:
- packages/lint/src/validate-expressions.ts:1190's FieldTraversalSlot still covers the three predicate slots only.
- planFormulaProjection (packages/objectql/src/engine.ts:1659) still projects the row's own columns.
- So a formula expression reading record.<lookup>.<field> is accepted where it is declared and reads null where it runs.
Why p1 + target:v18: declared ≠ enforced, the shape A field-level requiredWhen / readonlyWhen that reads through a lookup (record.account.tier) is accepted at authoring, but the runtime never hydrates it, so since ADR-0137 D2 every write that reaches it is refused #20078 closed for predicates. Either direction is a metadata-protocol change: (a) widens the formula read path, (b) narrows what the lint accepts.
Waits on the direction. It is the open question on objectstack-ai/cloud#2925, with the maintainer, seat lean (a). ⛔ No Blocked-by: line is written: under (a), cloud#2925 itself waits on this card, so a closure-gated line would deadlock. Triage releases this card when the ruling is recorded.
Scope after the ruling: the chosen direction, the producers named in the repo:cloud#2 seat's comment (the blueprint schema's describe strings, solution-blueprint.zod.ts :95 / :107, and their strict twins), and a pin with an ablation.
Lane: domain:engine (packages/objectql read path, or the lint pass under (b)).

File surface:

packages/objectql/src/record-title.ts (resolveRecordTitle, and a sibling if one is needed) and, only if the title needs it, the formula seam it calls in packages/objectql/src/engine.ts (evaluateFormulaField and the one-hop loader resolveOneHopRelated, reused, never re-implemented).
Cross-lane, declared to domain:cli on [PM seat] domain:cli — 🟢 zhuangjianguo · session_01SYEJqDL3NXxrJRBVqaMu9T #6024 and [PM seat] domain:cli · seat 2 — ⏳ vacant #22648: packages/runtime/src/sandbox/body-runner.ts, buildTitleSurface only. Both forms are in scope: ctx.title() (this record, the state the hook fires on) and ctx.title('field') (the related record, read through the body's own ctx.api channel). Each must answer a composed title over lookups that the REST read now answers.
Pins beside each, and one changeset per package touched, .changeset/24197-*.md.

Responsibility: buildTitleSurface evaluates a formula title with the synchronous evaluateFormulaField, which preloads no hop, both for this record and when re-deriving the related record's title over the row findOne already served. So a composed title over lookups answers undefined in a hook body while every REST read shows it | the platform path that already serves the hop is the engine read path (PR feat(objectql,lint): a formula field reads one hop through a reference — record.book.title computes, a second hop is refused #24274) | every hook or action body that calls ctx.title() on a junction object; the exemplar app's bodies compose titles this way (body-runner.ts's own docblock: four of five measured title pointers are formulas)

Queue	PR #24307 entered the merge queue at 2026-10-18T11:28Z, after ACCEPT 6249354253 and the `TIER_DEFAULT` record 6249342777 (PASS, declaration face). It left the queue merged at 2026-10-18T11:55Z. No `gh-readonly-queue/main/pr-24307-*` branch remains after the merge.
`origin/main`	`1bf5f6e17c` is on `origin/main` (`git merge-base --is-ancestor`: exit 0). It carries PR #24307's same 13 files, +670 / −52.
Cards closed	The PR says `Part of #24197`, so this card stays open and `pm:dispatched`, as intended. No other `domain:engine` card closed during the queue run.

Now on main:

In a hook or action body, ctx.title() evaluates the object's title formula over the in-flight record state. It serves the formula's one hop through a reference the way a read does: one batched read per reference field, on the body's own ctx.api channel, under that channel's identity and on its open transaction.
A related record the caller may not read, a missing one, or a second hop leaves the title null, as the REST read of the same record shows no title.
ctx.title('field') answers the related record's title exactly as its findOne served it.
@objectstack/objectql exports resolveServedRecordTitle, servedRecordTitle and the type FormulaServingChannel. ObjectQL and ScopedContext each gain serveFormulaField.

Remaining on this card: the ADR-0079 note, as its own Tier H PR (docs/adr/**, human merge). Its draft combines:

part 1's adr_note_text, amended with record 6247399985's ③.4 and ③.8b;
part 2's adr_note_addendum (report 6248949940);
record 6249342777's ③.7.

Rework (part 3) · domain:engine seat 1 · session_01JtSQQ3EWsbNPzyYMug1tXy · 2026-10-18T12:58Z.

Review: the CONTRACT_REVIEW_TIER record 6250184223 on PR docs(adr-0079): addendum — a formula title reads one hop through a reference, and is not sortable or searchable #24323 (head da22e1db2a) is FAIL on one statement, ①.10. The addendum's group heading says "Hook and action bodies", but ctx.title() is installed on the hook face only (packages/runtime/src/sandbox/body-runner.ts; the action face carries no title). Its items 1–9 are each read RIGHT against main. The fence holds, and the ruling is quoted verbatim.
Rework round 1 was sent to the dev session session_01RVjnmZ6Jv6NcLDwow6RpNi: the heading names hook bodies only, plus one provenance-wording nit. A fresh record follows on the new head.
PR body: the seat re-worded the Summary line through the relay. The case-insensitive Part of #N reader matched "the last part of A formula field that reads through a reference (record.book.title) passes validateExpression, then reads null on every row: the read path projects only the row's own columns #24197", and the Part-of PR must not also close its card guard went red on it. Fixes #24197 stays.
Correction to this seat's own landing comment 6249626252: its first "Now on main" bullet says "In a hook or action body". It should read "In a hook body". The action face has no ctx.title(). The wording came from part 2's carried adr_note_addendum.

Approval	Tier H (`docs/adr/**`). `os-zhuang`, a governed approver (`GOVERNED_APPROVERS`), APPROVED head `73fd87521c` at 2026-10-18T13:40Z. That came after the `CONTRACT_REVIEW_TIER` delta record 6250527790 (PASS, superseding FAIL 6250184223) and the seat's Tier H record 6250544233.
Queue	It entered the merge queue at 2026-10-18T13:40Z and left it merged at 2026-10-18T13:51Z. No `gh-readonly-queue/main/pr-24323-*` branch remains.
`origin/main`	`68a090fb97` is on `origin/main` (`git merge-base --is-ancestor`: exit 0). It carries PR #24323's one file, `docs/adr/0079-record-display-name.md`, +77.
Card	Closed `completed` through `Fixes #24197`; `pm:dispatched` is cleared.

The card, end to end:

PR feat(objectql,lint): a formula field reads one hop through a reference — record.book.title computes, a second hop is refused #24274 (d537a318b): a formula reads one hop through a reference field; the lint admits one hop and refuses two; a title formula over lookups is stored nowhere, so it is not sortable or searchable.
PR fix(runtime,objectql): ctx.title() answers a title formula over lookups — the one hop is served on the body's own channel #24307 (1bf5f6e17c): a hook body's ctx.title() serves that hop on the body's own channel.
PR docs(adr-0079): addendum — a formula title reads one hop through a reference, and is not sortable or searchable #24323 (68a090fb97): the ruling's ADR-0079 addendum, which states both.

Filed out of this card: #24284 (landed as PR #24320) and #24316 (security, in build). The dev session session_01RVjnmZ6Jv6NcLDwow6RpNi is archived.
