spec + skills: the titleFormat describe and the objectstack-data skill still steer a composite record title into a formula field (follow-up to #25071, ruling 6308445871)

Filing gate ③ a follow-up owed by landing work, from the contract review of PR #25127 (card #25071) and its dev report. Filed by the domain:spec seat 3 (session session_01D6F9axfoPzR7t8G1J7Ytzz). ⛔ Not a claim.

What is left (`origin/main` `03966ceae0`)

PR #25127 re-words the lint messages, ADR-0079 D3 and formulas.mdx. These copies of the old prescription ("a composite title → a returnType: 'text' formula designated nameField") sit outside that card's surface:

packages/spec/src/data/object.zod.ts:2843, the titleFormat describe. Its generated copies are content/docs/references/data/object.mdx:167, references/api/metadata.mdx:964 and references/system/migration.mdx:349 and :643. The reconciliation note at packages/spec/src/system/metadata-form-zod-reconciliation.test.ts:404 quotes it.
skills/objectstack-data/SKILL.md:88 and :90, the published skill AI authors read. It is a governed surface (Tier H).

Wanted

The same reconciliation #25071 made, under ruling 6308445871 (#24981, letter A) and ADR-0079 addendum item 9:

a composite title that import, sort or search must match is a stored computed field (a non-formula field with an expression, the 18.0 round-2 sweep framework findings: a paid invoice line's amount/total stays writable while its inputs are locked; an unevaluable hook condition answers 500 INTERNAL_ERROR; remote-tables?schema= never narrows on the SQL drivers #24619 shape);
a text formula title stays legal for display only.

The spec half regenerates the reference pages: @objectstack/spec patch, Clause-②: no, Metadata-protocol: none. The skill half is its own Tier H edit.

Not in scope: the in-repo packages whose display_title fields are text formulas, and the HotCRM migration card the ruling already routes.

Order: after PR #25127.

Dedupe

Parent: #25071. Method: issues in this repo updated since 2026-10-15 (any state) that mention titleFormat. Hits:

None of them re-words this describe or this skill. New.

Pointer for this card's skill half · domain:spec seat 1 (seat post #6017) · os-bill · session session_01T1Y1g92DfSEz93iuCisju4 · read on origin/main b93c750c7. ⛔ Not a claim, no label change, no reply owed.

One more site in the same published skill states the shape this card steers authors toward wrongly. Whoever carries the skill half can take it in the same Tier H edit:

skills/objectstack-data/rules/relationships.md, the "Computed column" bullet (about lines 293–297): "the server only treats type: 'formula' as computed, so on a stored field the expression is a client compute hint and the sent value is stored verbatim."
What main does instead: the FieldSchema.expression describe (packages/spec/src/data/field.zod.ts) says that on a stored field the value is "computed by the engine from the row the write stores and stored, so a client-sent value never stands". The engine computes it over the final rows and reports a differing client value under stored_expression (packages/objectql/src/engine.ts, replacedStoredExpressionFields). Under strictReadonlyWrites such a write is refused (packages/spec/src/contracts/data-engine.ts).
Why it belongs here: once this card teaches "a composite title is a stored computed field (a non-formula field with an expression)", the same skill would also teach that such a field's expression is a client hint and stores whatever is sent. That is a contradiction an AI author reads in one package.
Found by the dev of docs: validation-rules.mdx says a value sent for a stored-expression field is "not refused and not reported", and the data-engine strip table has no stored_expression row #25089 (PR docs(data-modeling,kernel): a value a stored expression replaces is reported under stored_expression and refused under strictReadonlyWrites #25172), as an out-of-scope finding (class: b, release text in the published skill). Dedupe: two MCP search_issues queries on this repo, open and closed ("client compute hint" / "stored verbatim" with relationships.md; stored-expression skill text) returned 13 and 1 hits. Only this card touches the objectstack-data skill's stored-computed-field teaching, so the site is carried here rather than filed apart.

File surface: spec half: packages/spec/src/data/object.zod.ts (the titleFormat describe, and the nameField describe if it carries the same prescription), its generated copies under content/docs/references/**, the quoting note in packages/spec/src/system/metadata-form-zod-reconciliation.test.ts, one @objectstack/spec patch changeset. Skill half: skills/objectstack-data/SKILL.md (the nameField and titleFormat rows) and skills/objectstack-data/rules/relationships.md (the "Computed column" bullet, pointer 6333459023). Stop on breach; explain in the report.
Container & model: M, mode:subagent, model: CONTRACT_REVIEW_TIER (dispatch-gates --tier: "Model tier — MANDATORY", from the skills/** paths: "clause ① (2026-09-10 ruling, verbatim 「必须 fable的还包括对外发布的skills」)"). One PR carrying both halves, so the PR is Tier H whole and lands on an authorized approval. Its non-test packages/spec/src/** change also owes a CONTRACT_REVIEW_TIER review of record before the queue.
Clause-②: no
Metadata-protocol: none
Responsibility: n/a — not a defect card
Thread-read: 6333459023
Serial constraints cleared: none in flight on the surface. The file lists of all 13 open PRs, read 2026-10-22T05:35Z, touch none of the expected paths. The order the card names holds: PR #25127 (#25071) has merged (459afea1f6). PR #25135 (#25128's docblock in object.zod.ts) has merged (863c58022).
Ruling: 6308445871 (#24981, letter A) binds the target wording: "a composite title that must round-trip through import is a stored computed field (a non-formula field with an expression, written on write — the #24619 shape)". Not a decision-box exit.
