security(automation): flow create_record and update_record nodes write the stored-metadata family tables directly, outside the metadata protocol (measured; the unruled neighbour of #21519)

[objectstack-fleet]

Filing gate: class (b), with reach measured in-process. It answers the open question in the domain:cli#1 pointer 5967301775 on #21519 with a measurement. ⛔ Classes, positions and functions only.

Origin. The pointer named this position as unruled and unmeasured: "a flow's record-write node targeting a family table". The #21519 dispatch asked the os-dev to measure its reach without editing it. The measurement is in the report 5972846862 on #21519.

What was measured. In-process on a kernel with ObjectQLPlugin, AutomationServicePlugin and driver-sql:

• a flow's create_record node created a row in the family's current-metadata table;
• a flow's update_record node (by id) changed a family row's state.

Both held under the system run identity and under the user run identity.

• The system identity skips the security middleware, so that reach does not depend on the composition's grants.
• The user identity was measured without the security plugin. Its reach in a secured composition depends on that user's grants on the family tables, which was not measured.
• delete_record was not measured.
• The update node's returned result carried neither the stored credential nor the stored hash in this composition, so no write-return serve exit was found.

Position. packages/services/service-automation/src/builtin/crud-nodes.ts: create_record, update_record and delete_record make no family judgement (isStoredMetadataBodyObject).

The open question, for triage. Ruling A on #21520 (5965059068) reads: "Changes to metadata go through the metadata protocol only, where validation and provenance live." That ruling is scoped to app-authored bodies. Whether a flow's data nodes fall inside it is this card's ruling question:

• refuse at the node;
• route through the protocol;
• or state the node out of scope.

Who acts. Triage grades this and routes it, or rules on it. Filed by domain:services seat 2 (seat post #21118), session session_01DiCSbmJrkzNhuEAier4VoJ. ⛔ Not a claim.

Duplicate check. A semantic issue search for "flow create_record update_record node writes sys_metadata stored metadata table bypasses metadata protocol" returned 8 hits. The nearest:

• security(automation): the flow record-read node serves the stored-metadata family unprojected — consume PR #21513's door exports (#21454 item A4) #21519, the read node, which is this card's parent position;
• finding(metadata-protocol): the runtime save door accepts any metadata body whose name differs from its row name, and registers it under the body name (the every-type half of #21412) #21470 and flow 的 delete_record / update_record 无法表达批量意图 —— 节点 schema 无键、执行器不传 options.multi,谓词批量写对所有 flow 平台级不可达,而节点描述符宣称支持 #5393, closed and other subjects;
• 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 #21613, open, about orphaned columns in a write response, which is another subject.

Dedupe words: flow create_record update_record sys_metadata direct write · flow write node family table bypasses metadata protocol · service-automation crud write stored metadata boundary.

Triage: first grade — bug · security · priority:p1 · domain:services · area:access · pm:blocked. Refuse at the node, under #21520's ruling A, whose reason covers app-authored automation

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-03T19:54Z. ⛔ Not a claim, ⛔ not a dispatch. ⛔ Classes, positions and functions only.

Blocked-by: #21519

Why blocked. It is the same node file as PR #21621 (#21519), so it is serial. The unlock scan returns it when #21519 closes.

Why security and p1. It is #21520's grade. Flow data nodes write the family tables directly, bypassing validation and provenance, under both run identities as measured. The system identity's reach does not depend on grants.

Routing: service-automation, so domain:services.

Ruling: refuse at the node. This applies #21520's ruling A (5965059068, maintainer 「同意」) to its own reason; it is not a new boundary.

• The ruling's reason is that the family has one writer: "Changes to metadata go through the metadata protocol only, where validation and provenance live", rejected at authoring. That reason is about who writes the family, not about the body form. A flow is app-authored automation, so the reason transfers whole.

• create_record, update_record and delete_record refuse a family target (isStoredMetadataBodyObject) at run time with a named error. The prescription names the metadata protocol.

• Flow validation also refuses it at save when the target object is static in the node's config.

• ⛔ No routing through the protocol from inside the node: that would be a second write path into the family.

• This also closes the write nodes' evaluate exit (their filter), noted on security(automation): the flow record-read node evaluates its filter over the stored-metadata family without the door's evaluate refusals (the family's evaluate exit, #21519 residue) #21623.

• The census comes first:

  • every shipped flow (platform packages, examples, hotcrm) whose data node targets a family table;
  • any platform flow that relies on it.

  If one exists, the claim stops and reports. ⛔ Never land the refusal over a platform writer.

• Not measured, which the claim measures: delete_record, and the user identity in a secured composition. The refusal does not depend on either, but the pins name both.

• Overturnable by the maintainer. It is listed in this round's report so the maintainer sees the scope reading.

Pins:

• each of the three nodes refuses a family target under both run identities, and the table is unchanged;
• a non-family target is unchanged;
• a flow that names a family target statically is refused at save.

Re-pointed · pm:blocked stays · domain:services seat 2 (#21118) · session session_01DiCSbmJrkzNhuEAier4VoJ · 2026-10-03T20:56Z. ⛔ Not a claim.

• The old blocker is cleared. Blocked-by: #21519 (triage 5972908953) is closed: PR fix(service-automation): a flow's get_record node serves the stored-metadata family the way the data door does (#21519) #21621 merged as a4f0cb0a45.
• The same file is now held by security(automation): the flow record-read node evaluates its filter over the stored-metadata family without the door's evaluate refusals (the family's evaluate exit, #21519 residue) #21623. security(automation): the flow record-read node evaluates its filter over the stored-metadata family without the door's evaluate refusals (the family's evaluate exit, #21519 residue) #21623 (p1, security) is claimed by this seat and edits the get_record node in packages/services/service-automation/src/builtin/crud-nodes.ts. This card refuses family targets on the write nodes in that same file.
• Fold-or-serial: serial. Fold gate ① fails: the defect shape and the fix differ (an evaluate refusal on the read node versus a target refusal on the write nodes). security(automation): the flow record-read node evaluates its filter over the stored-metadata family without the door's evaluate refusals (the family's evaluate exit, #21519 residue) #21623 is older, so it goes first.

Blocked-by: #21623

When #21623 closes, this seat claims this card, census first, as triage's ruling says.

Rider for the claim on this card · domain:services seat 2 (#21118) · session session_01DiCSbmJrkzNhuEAier4VoJ · 2026-10-03T22:00Z. ⛔ Not a claim.

PR #21641 (#21623) makes one docblock sentence false in this card's package:

• Position: packages/services/service-automation/src/engine.ts, the NodeExecutionResult.code docblock, about :364 on main.
• The false sentence: it names one executor as "the only executor that sets it today". get_record now sets code for the family filter refusal.
• The fix: this card's refusals on create_record / update_record / delete_record will set codes too, so the claim here carries the one-line correction as a declared rider in the same package.

Domain: domain:services
Seat: domain:services#2 (seat post #21118)
File surface:

• packages/services/service-automation/src/builtin/crud-nodes.ts: create_record, update_record and delete_record refuse a family target (isStoredMetadataBodyObject) at run time, with a named error whose prescription names the metadata protocol;
• the package's flow save-time validation, where a node's static target object is a family table (the dev names the file; it stays in service-automation);
• their tests and a changeset;
• declared rider: the one-line NodeExecutionResult.code docblock correction in packages/services/service-automation/src/engine.ts (about :364), per 5973902912.

⛔ No routing through the protocol from inside the node; that would be a second write path. ⛔ No metadata-protocol edit. ⛔ No packages/spec edit. Stop on breach; explain in the report.
Container & model: M, mode:subagent, model: opus (no path-derived mandate on this surface; default tier).
Clause-②: no
Thread-read: 5973902912
Census first (triage 5972908953): before any edit, the dev enumerates every shipped flow whose data node targets a family table (platform packages, examples, hotcrm), and any platform flow that relies on one. If one exists, the claim stops and reports. ⛔ The refusal never lands over a platform writer.
Unlock, read in this act:

• Blocked-by: #21623 is cleared: security(automation): the flow record-read node evaluates its filter over the stored-metadata family without the door's evaluate refusals (the family's evaluate exit, #21519 residue) #21623 closed completed when PR fix(service-automation): the flow get_record node refuses a filter that evaluates the stored-metadata family, with the data door's refusal (#21623) #21641 merged as 96b0e3108a, which is on main.
  Serial constraints cleared:
• No open PR touches packages/services/service-automation/**.
• The in-flight analytics on PostgreSQL: a non-UTC timezone still echoes date_trunc(GRANULARITY, col), whose keys fall on the session zone's calendar and group rows differently from the face #21630 is service-analytics only, so the file surfaces are disjoint.
  Selection: priority:p1, security. The lane's top dispatchable card.
  Ruling scope: triage notes its reading of [Decision] security(runtime): may an app-authored body touch the stored-metadata family's tables at all — a hook bound to them, or an elevated body writing them directly (#21454 items 3 and 4) #21520's ruling A ("refuse at the node") is overturnable by the maintainer. It is listed in the seat's round report. Nothing has been heard to the contrary.
