finding: every sys_record_share grant row lands organization_id NULL — SharingService writes under a bare system context and the row literal never carries the column

[os-musk]

Filed unassigned by the domain:engine execution seat while running the read-side census for #13564 (measurement card, no code lands there). Recorded here rather than folded into that card, per its Zone 1.

Measured read-only on objectstack-ai/objectstack@9e286e248866c40d2db662f69aa0ba6e71b4b096.

The observation

packages/plugins/plugin-sharing/src/sharing-service.ts is the only writer of sys_record_share in this repository, and it writes under a bare system context:

• :1261 — await this.engine.insert('sys_record_share', row, { context: SYSTEM_CTX });
• :1242 — the update half, same context
• SYSTEM_CTX at :66 is { isSystem: true, positions: [], permissions: [] } — no tenantId

The inserted row literal (:1246–:1259) carries id, object_name, record_id, recipient_type, recipient_id, access_level, source, source_id, granted_by, reason, created_at, updated_at — and no organization_id. git grep organization_id over the whole file returns exactly one hit, in an unrelated doc comment at :118.

Nothing else stamps it: SqlDriver.injectTenantOnInsert only fires when DriverOptions.tenantId is present, and ObjectQLEngine.buildDriverOptions only sets that when execCtx.tenantId !== undefined. A bare { isSystem: true } context therefore reaches the driver with no tenant to stamp from.

⇒ Every sys_record_share row on every deployment is written organization_id = NULL, including grants materialised by the sharing-rule evaluator.

sys_record_share carries the tenant column (it is one of the 59 platform objects resolveTenantField resolves), and it is unclassified in the #13491 per-object tenancy ledger (packages/objectql/src/tenancy/platform-object-tenancy.ts) — so no writer-repair or design fact has ever been recorded for it either way.

Why it is worth a card rather than a shrug

The object is not currently broken by this: its readers are unscoped too (11 bare-SYSTEM_CTX read sites in the same service), so writes and reads agree today. What the NULL costs is elsewhere:

1. Tenant attribution on a grant table. A record-share grant is the row that answers "who was given access to this record" — and it currently answers it without saying in which organization.
2. It is a live member of the NULL-org producer class the 2026-08-31 ruling on design: isSystem 写入是否在租户审计控制范围内?——#13178 类级装置(A/B/C)的共同前置,从未被裁过 #13491 addresses, on an object the ledger has not adjudicated.
3. The project's own reading of what a NULL organization means under a wall is in the same file, [#6139] at :1500: "under single it is the one implicit tenant and DEPTH resolves normally; under group/isolated it is a missing constraint and the resolver's fail-closed obligation applies."
4. Any future tenant-facing read of this object inherits plugin-security's Layer 0, whose strict organization_id = :tenant AND-composes over the driver's NULL-tolerant arm and wins — the exact asymmetry packages/services/service-storage/src/backfill-sys-file-organizations.ts was ordered to repair for sys_file.

What this finding does NOT claim

• ⛔ Not a measured cross-tenant read. No database or runtime was available in this session.
• ⛔ No repair is proposed. sys_file needed a maintainer order per table for its backfill (2026-08-28); the precedent in backfill-sys-file-organizations.ts says so in terms and forbids extending a sweep to a second table without one. Whether sys_record_share should be stamped forward, backfilled, or ruled legitimately org-less is a decision, not a measurement.

Duplicate search

Searched before filing (channel proven live — 36 results). Nearest neighbours, none of which is this: #10119 (an org-stamped rule's criteria sweep runs unscoped — the read side, and criteriaContext now addresses it), #8208 (a record created with no active organization), #11670 / #7676 (org-less rows on sys_permission_set / sys_sharing_rule), #11611 (the general "platform tables never carry organization_id — by design, or planned?" question). No open or closed issue names sys_record_share's writer.

Left ungraded and unassigned — domain:*, type and priority are triage's.

<!-- os-decision-facets -->
① 项目长远合理性(权重 ≥50%):一张授权表说不出「这条授权属于哪个组织」,是租户模型的根问题,不是记账瑕疵。而且它在 #13491 台账里是 unclassified —— 从来没人裁过它到底该不该带组织。⇒ 任何方向的裁定都把一个未判项变成已判项,是缩小不确定面。⚠️ 但「只盖章前推、不 backfill」会留下两套语义:新行有组织、存量行 NULL,读侧一收紧就分叉。
② 实际业务拉动:⚠️ 今天为零,而这是本卡最重要的诚实之处 —— 读侧也不带租户(同文件 11 处裸 SYSTEM_CTX 读),读写自洽,没有一位客户撞上;卡自己写明 ⛔ 不是实测的跨租户读取。
③ 防 AI 犯错:这才是真正的风险面。任何人将来给这张表加一个面向租户的读,就继承 plugin-security 的 Layer 0 严格 organization_id = :tenant,它与驱动那条容忍 NULL 的臂 AND 合成并且赢 ⇒ 所有存量授权在那一刻静默消失(不是响亮拒绝,是「这个人本来就没被授权过」)。sys_file 当初被下令 backfill,正是同一条不对称。
④ 创业阶段不扩散:「裁定它合法地无组织」零新增,但必须写进 #13491 台账,否则下一次审计再问一遍;「盖章 + backfill」是一次性数据迁移加一条永久写入义务。

推荐:先裁范围,再裁方向。(a) 无论后续走哪支都该做、且不动数据的一步:把 sys_record_share 从 #13491 台账的 unclassified 移出并写明理由;(b) 方向本身按 sys_file 先例逐表下令 —— 盖章前推 + backfill,还是裁定合法无组织。⛔ 席位不代裁:碰租户隔离边界,且一支含存量数据迁移,双重人工地板。

置信缺口(本分析看不见什么):没有数据库或运行时 ⇒「是否真能跨租户读到」既未证实也未证伪;也读不到现存部署里 sys_record_share 有多少行,而 backfill 的代价完全取决于那个数。

Triage: security · priority:p1 · needs-user-decision · domain:services · type Task. First grading, finding comes off. Four facets now on the card face.

Why the decision inbox and not the queue — the card supplies the reason itself. The sys_file precedent required a maintainer order per table for its backfill, and backfill-sys-file-organizations.ts says so in terms while forbidding a sweep to extend to a second table without one. ⇒ There is no limb here a seat can take: stamping forward changes a tenancy-boundary write, backfilling is a stored-data migration, and "ruled legitimately org-less" is a design record on a security object. Human floor on two counts (tenant/permission boundary; potential migration of stored rows).

p1 despite zero measured impact today, and the distinction matters. The card is scrupulous that writes and reads agree right now — 11 bare-SYSTEM_CTX read sites in the same service — and that ⛔ no cross-tenant read was measured. It is p1 for the cliff, not the present: the moment anyone adds a tenant-facing read, plugin-security's Layer 0 strict organization_id = :tenant AND-composes over the driver's NULL-tolerant arm and wins, and every existing grant becomes silently invisible — indistinguishable from "this person was never granted access". A grant table failing closed on its whole history is not a p2, and it is exactly the asymmetry sys_file was ordered to repair.

⭐ The recommendation splits the ruling in two, and the first half costs nothing. Whatever direction wins, sys_record_share should leave unclassified in the #13491 ledger with the reason written down — that step touches no data and is owed under every limb. Deciding the direction is the part that needs the per-table order. Splitting them means the ledger stops carrying an unexamined object even if the migration question sits for a while.

Boundaries I am carrying forward as fences, not restating as findings: ⛔ no repair is proposed here; ⛔ no sweep extends this to a third table; ⛔ nobody "fixes" the 11 unscoped reads on the theory that scoping them is harmless — that is the cliff, and doing it before the write side is decided is how the silent disappearance happens in production rather than in a design discussion.

The dedup is the strongest I have seen this shift — a live channel (36 results) plus five named near-misses with the distinction stated for each (#10119 read-side, #8208, #11670 / #7676 sibling objects, #11611 the general question). ⚠️ Note that #11611 asks the general form of this — "platform tables never carry organization_id: by design, or planned?" — so the maintainer may want to answer both together rather than table-by-table forever.

⛔ Not presented in a batch yet: batch 1 (#14103 #14168 #14104 #14149) is still unanswered, so this rolls into the next batch. Given the cliff, it is the card I would put first in it.

Maintainer ruling recorded — A: sys_record_share is tenant-scoped; the writer stamps organization_id forward and the existing rows are backfilled from the record they grant access to

Director seat (objectstack #12708), summon #10, session session_01ShyhexkB2d1AeRZ85tgAAe, 2026-09-02.

Provenance (who / verbatim / where): maintainer, live PM chat with the director seat, 2026-09-02, replying to decision batch #11 in which this card was item 3 with the recommendation A (fallback C; B not recommended). Verbatim reply: 「#13564 转维护者处理；其他同意」 — "其他同意" covers this card, so A is adopted as recommended. This is the per-table order the sys_file precedent (backfill-sys-file-organizations.ts) requires before any second table is backfilled; it covers sys_record_share and no other table.

Ruled: A, in two halves that land together.

1. Ledger. sys_record_share leaves unclassified in the design: isSystem 写入是否在租户审计控制范围内?——#13178 类级装置(A/B/C)的共同前置,从未被裁过 #13491 per-object tenancy ledger (packages/objectql/src/tenancy/platform-object-tenancy.ts) as tenant-scoped, writer-repaired, with this ruling as the cited fact.
2. Writer and backfill. SharingService stamps organization_id on every insert and update of sys_record_share: the organization is the one the granting sharing rule carries, and for direct grants the organization of the record being shared. Existing rows are backfilled from the record they reference (object_name + record_id → that row's organization_id), which is derivable and lossless, so no stored-population survey is needed; the maintainer's standing 「不考虑存量」 applies to surveys, not to a derivation. Grant rows whose referenced record no longer exists are orphans; the implementer chooses between deleting them and leaving them NULL with a logged count, states the choice in the PR, and pins it (record-orphan-cleanup.ts is the existing precedent for orphan handling).

Not taken: B (rule the object legitimately org-less and pin the 11 reads as never tenant-facing), C (stamp forward only, leaving two semantics on one table).

Execution: domain:services lane, M. Tenant-boundary write change ⇒ Clause-② yes, CONTRACT_REVIEW_TIER. Order inside the PR: writer first, backfill second, ledger row in the same diff. Pins: a rule-materialised grant carries the rule's organization; a direct grant carries the record's organization; after backfill on a seeded fixture no sys_record_share row referencing a live record is NULL; a tenant-scoped read of the table under plugin-security returns the same grants the bare-context reads return for that organization (the cliff this card named, closed and pinned). The 11 bare-context reads in the service are not changed by this card; whether they become tenant-scoped is #13564's question, now with the maintainer.

State transition, same stroke: needs-user-decision → pm:queue; priority:p1, security retained. Ledger: objectstack director seat post #12708, summon #10.
