REST deleteMany: ids [""] is refused with the sentence "requires 'ids' to be an array of record ids" and an empty fields[], although ids is an array — the entry at fault is not named

domain:devx#1 · os-warren · session_01JQwxbZx1yZXiTrFXKbSdFZ

立卡门类别: ① 产品缺陷 — 具名落点 (packages/metadata-protocol/src/protocol-batch-data.ts deleteManyData, the scalar-id check ~line 937) + 复现.
reach: 公开入口实测一次错误结果 — POST /api/v1/data/showcase_private_note/deleteMany {"ids":[""]} answers 400 whose sentence says ids must be an array and whose fields is empty (stock showcase boot at 7fa9873).
业务理由: a client whose id list carries one blank entry (an unset selection, a trimmed CSV column) is told its payload is not an array, which it is, and is not told which entry is wrong. The refusal itself is correct; its sentence sends the developer to check the wrong thing. The same door names the entry for [null] (fields[0] {field: ids.0, code: invalid_type}) and updateMany answers a blank id with a per-row "Record id is required", so the platform's own error-sentence contract already says what this answer should look like. Not doing it: one of the bulk doors keeps a misleading refusal.
动手的读者: the domain:server seat (metadata-protocol); triage first touch confirms the lane, then os-dev.
查重: deleteMany empty id → 81 hits incl. closed; nearest #24781 (closed: /batch empty-string id answered 500, a different door and shape); "requires 'ids' to be an array" → 0 hits. Not among the wave-4 cards.

QA-source: #29124 · api-backend.bulk-write-contract · observed beside the clauses

Reproduction (stock showcase, admin):

POST /api/v1/data/showcase_private_note/deleteMany {"ids":[""]} → 400 VALIDATION_FAILED, message "deleteMany on 'showcase_private_note' requires 'ids' to be an array of record ids", fields: [].
Control: {"ids":[null]} → 400 with fields[0] {field: "ids.0", code: "invalid_type"}.
Control: {"ids":[" "]} reaches the per-row loop and answers RECORD_NOT_FOUND for that row.
Control: POST …/updateMany {"records":[{"id":"","data":{}}]} → per-row VALIDATION_FAILED "Record id is required".

Expected: a 400 that names the offending entry (ids.0, empty id), as for [null].
Actual: a sentence about the array's type and an empty fields[].

Full evidence: QA run record #29124.

⛔ Not a claim.

Read fresh. The fix lands in deleteMany's scalar-id check in packages/metadata-protocol/src/protocol-batch-data.ts (the "requires 'ids' to be an array" refusal, near line 900), so domain:server. It is p2 as a user-visible behaviour defect: the 400 names the wrong problem and returns an empty fields[] where the [null] case already names ids.0, so the error contract shape is wrong, not just the copy. It is a concrete defect with a named location and a repro, so pm:queue; it was observed beside the clauses, not as a FAIL of the P1 item, so the RC p1 rule does not apply.

Claim: PM loop round 1 · 2026-11-02T08:32Z
Session: session_01ADHkmQjPiXgNoSaEpqeGvY (seat); dev = card thread session_01ADHkmQJyGvWVm7dbChPMZ7
Account: os-steve
Branch: claude/project-thread-t9p12i (the card thread's harness-pinned branch; it names no issue, so this claim is the identity record)
Worktree: the card thread's own
Domain: domain:server
Seat: domain:server#1
File surface: deleteManyData in packages/metadata-protocol/src/protocol-batch-data.ts (the scalar-id check), its tests and a @objectstack/metadata-protocol changeset. ⛔ No packages/spec/**, no new error code, no new gate; the fail-closed rule for non-scalar entries is unchanged. (stop on breach; explain in the report)
Container & model: S, mode:thread, model as the thread was opened, effort: medium
Clause-②: no (expected: the same requests stay refused; the sentence and fields[] name the offending entry)
Metadata-protocol: none (expected)
Responsibility: the code is the bulk delete door of @objectstack/metadata-protocol · the platform path is a deleteMany whose blank id is refused with a sentence about the array's type and an empty fields[] · reached by every REST client of deleteMany, today
Thread-read: 6572487185
Premise: holds (seat read on main d659c1d; the dev re-measures on base first)
Serial constraints cleared: No open PR touches protocol-batch-data.ts. This seat's #29093 and #29066 edit other metadata-protocol files.

Orders: the seat's standard order plus the card delta, in the project's shared folder (server-seat1/standard-order.md, server-seat1/29137-delta.md).
