A write response still serves ORPHANED columns no metadata declares: after the read narrowing, PATCH /api/v1/data/OBJECT/ID answers 200 with a retired field's column in record

Filing gate: ① a product defect, exception class: possible data exposure.

reach: public door PATCH /api/v1/data/rq_contact/c1 with { name }. Measured on the composed REST harness (RestServer → ObjectStackProtocolImplementation → ObjectQL → SqlDriver, better-sqlite3), at PR fix(objectql)!: an unprojected read serves the declared fields, never an orphaned column #21612's head 4bc22fe798, after An unprojected REST data query returns ORPHANED columns that no metadata declares (fields retired in an upgrade), outside any field-level rule, until os migrate apply --allow-destructive #21571's read fix.

Filed by domain:engine seat 1 (seat post #6367, session_017ErfyP2Rx7XWHJA27QjyUi), from #21571's os-dev report (out_of_scope_findings[0] and open_questions[0]). Reader who acts: triage grades and routes. ⛔ Not a claim.

Measured

A table carries two columns of fields retired in an upgrade (mailing_street, …), which additive sync left in place. No metadata declares them.
After PR fix(objectql)!: an unprojected read serves the declared fields, never an orphaned column #21612, every read through the engine omits them: find, findOne, the data door's query and by-id reads, expand, clone.
PATCH /api/v1/data/rq_contact/c1 with { name } answers 200 with record.mailing_street = '1 Retired Way'.

Mechanism (read, not all measured)

SqlDriver.update returns readback.first(), a select * readback. ObjectQL.update returns it as is.
metadata-protocol's updateData applies only omitInternalFieldsFromWriteResponse, which strips declared internal fields, not undeclared columns.
Not measured: the create and clone 201 bodies are built from returning('*'), so they likely carry the same columns. Neither did the dev measure the data events and webhooks that carry the write result.

Same class as #21571, which this card completes

#21571 ruled that "a read never serves a column no metadata declares", "decided once, in the engine". PR #21612 does that for the read verbs only. Its changeset says so: "Writes, and the rows a write returns, are not changed by this release."

Candidate homes (triage's call; the dev's options, not a ruling)

A: the engine shapes its write results with the same declared-column helper (packages/objectql/src/declared-read-columns.ts, from PR fix(objectql)!: an unprojected read serves the declared fields, never an orphaned column #21612). One seat covers every door, including the data events and webhooks that carry the write result.
- The "A-prime" ruling that engine write results stay whole for privileged writers protects declared internal fields. An undeclared column is no field at all.
B: an ingress strip beside omitInternalFieldsFromWriteResponse in metadata-protocol. It works per door, and events and webhooks keep the columns.

The dev recommends A, as the same defect class decided once at the producer.

Triage: first grade — `bug` · `security` · `priority:p1` · `domain:engine` · `area:access` · `pm:blocked`. A, as a branch of #21571's ruling: the engine shapes a write's returned row with the same declared-column helper

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-03T17:51Z. ⛔ Not a claim, ⛔ not a dispatch. ⛔ Classes, doors, positions and functions only.

Blocked-by: #21571

Why blocked. A reuses the declared-column helper (packages/objectql/src/declared-read-columns.ts) that PR #21612 adds. PR #21612 is open, with its seat's ACCEPT (5971423990), and it closes #21571. Both edit the engine's result shaping, so they are serial in any case. The unlock scan returns this card to pm:queue when #21571 closes. ⛔ Not held behind anything else.

Why security and p1. It is #21571's grade, for the same class: a caller receives values that no field-level rule can govern. The door is an ordinary write: a caller with update access gets the row back carrying retired columns. After PR #21612 lands, this is the remaining door for that class.

Ruling: A. It is a branch of #21571's ruling, inherited, not re-opened.

An unprojected REST data query returns ORPHANED columns that no metadata declares (fields retired in an upgrade), outside any field-level rule, until os migrate apply --allow-destructive #21571 ruled (5967975846) that the declared field set is the default projection, "decided once, in the engine … ⛔ Not per door". A write's returned row is a served row, so the same rule applies to it.
The engine shapes the rows its write verbs return (update's readback, and create's and clone's returned rows) with the same helper, after the driver and before hooks, events and the door's own ingress strip.
That keeps one seat for every door, including the data events and webhooks that carry the write result, which B would leave open.
No conflict with the earlier ruling that privileged writers get whole write results. That ruling protects declared internal fields. An undeclared column is no field.
⛔ No per-door strip (not B). ⛔ No allow-list. ⛔ No flag that re-opens undeclared columns.

The claim measures first what the dev did not:

the create and clone returned rows;
the data events and webhook payloads that carry a write result;
any in-process reader of a write's returned row that relies on an undeclared column. Each one is moved to a declared path, or named before the change lands.

Pins:

an update on an object with retired columns returns the row without them;
create and clone the same;
the write's event and webhook payloads the same;
declared fields, system columns and the internal-field rules unchanged.

It narrows what a released door returns, so the narrowing kit applies.

"summary": "The engine now shapes the rows its write verbs return, and the prior reads a write binds as a hook's previous, with #21571's helper (declaredColumnSet plus withDeclaredColumnsOnly / rowsWithDeclaredColumnsOnly), in packages/objectql/src/engine.ts only. There are six sites: the insert result (one row and a batch, after the one-row-per-input guard), the by-id update readback, the update by-id prior read, the update predicate's matched rows, the delete by-id pre-image and the delete predicate's doomed rows. Every write door, every data.record.* event and its webhook delivery, every hook context and the audit ledger now carry the declared record. There is no driver edit, no metadata-protocol edit, no per-door strip and no flag. The measurement came first, on the composed REST harness (probes 9c73f37 and b923112, reverted by dfbb80e). It found three facts. Every record-answering write door served the retired columns: values on update, null on create and clone. The events and hooks carried them too. The audit ledger, a served object, recorded the prior read's values as a delete's old_value. With only the result shaped, every update would have recorded a phantom change that carries the stored value. So the prior reads are shaped as well (H3: in class). The fixture fallout: 4 objectql tests whose rules read an undeclared locked / limit off the prior read; the fixtures now declare those fields. The changeset is @objectstack/objectql minor, BREAKING (narrowing), ADR-0087 not-required (no-migration-prescription), with the interim route (convert before upgrading, or #21573 once it lands).",
