docs: `state-machine.mdx` 仍称 preserveAudit 的 readonly 白名单让 upsert「不再静默丢弃」—— create 半边不成立（#6640 收窄后的残留）

[os-zhuang]

事实

content/docs/protocol/objectql/state-machine.mdx:113 关于 treatAsHistorical / preserveAudit 的那条 bullet，把 readonly 白名单豁免描述成对 upsert 的两半都成立：

…and (2) admits a whitelist through the static-readonly write strip: the audit/timestamp family plus author-declared business readonly fields (closed_at, resolved_by, …), so an upsert refresh no longer silently drops them.

实际只有 update 那一半为真。create 半边走的是 DataProtocol 入口剥离（packages/metadata-protocol/src/protocol.ts 的 stripReadonlyForInsert，#3043），它只认 context.isSystem，从不读 preserveAudit。一次 treatAsHistorical 的 upsert 导入，因此在它更新的行上保留 closed_at，在它新建的行上照旧剥掉。

这正是 #6640 记录的那句话（其正文里已点名这条 state-machine 文案），但 #6640 的 file surface 只覆盖 security.mdx 的 preserveAudit 段、field.zod.ts 的 describe 与重新生成的 reference 文档，没有 state-machine.mdx，所以 PR #6823 按纪律没有动它 —— 留下这一处仍与收窄后的契约相抵触。

影响

维护者 2026-08-08 对 #6640 的裁决（option 2 + loudness rider）已把契约收窄为「豁免仅在 UPDATE 路径成立」，并由 PR #6823 落到 .describe() 与 security.mdx。这条 bullet 是同一主张在文档里剩下的最后一处旧说法：读者据此设计一次历史 upsert 导入，会预期新建行也保留 closed_at，而实际拿到的是被剥掉的列（现在附带一条 WARN）。

顺带记录第二处、更轻的一处：content/docs/references/kernel/execution-context.mdx:69 的 preserveAudit 行描述为空，因为 packages/spec/src/kernel/execution-context.zod.ts:356 的 preserveAudit: z.boolean().optional() 没有 .describe()（语义只写在上方 348 行的块注释里）。同一裁决之后，这里正好是写下「UPDATE 路径豁免；INSERT 侧须走 system 上下文」的地方。是否合并处理交由分诊。

建议修法

1. 把 bullet (2) 的主张限定到 update 半边，并点明 create 半边只认 isSystem（措辞可直接沿用 PR fix(metadata-protocol,spec): preserveAudit is UPDATE-only — narrow the contract and warn loudly on a non-system INSERT (#6640) #6823 在 security.mdx 里落的 callout，保持一处口径）；
2. 可选：给 ExecutionContextSchema.preserveAudit 补一条 .describe()，让生成的 reference 行不再为空（会触发 check:docs 的重新生成，须整体重跑生成器）。

Blocked-by: PR #6823（#6640）—— 收窄后的规范措辞以那条 PR 落地的 security.mdx callout 为准；在它合并前改这里会有两套说法。

Triage: pm:queue + pm:blocked + domain:devx — concrete, anchored docs residual of an already-made ruling; blocked on the upstream PR the card itself names (its body carries the machine-readable Blocked-by: line, so the pair is complete).

• Anchors (read, not inferred): verified on origin/main @ e120a5a+ — content/docs/protocol/objectql/state-machine.mdx:113 still claims the readonly whitelist means "an upsert refresh no longer silently drops them" with no update/create split; packages/spec/src/kernel/execution-context.zod.ts still has preserveAudit: z.boolean().optional() with no .describe() (semantics only in the block comment above).
• Ruling status: the [观察] stripReadonlyForInsert 完全不读 preserveAudit —— readonly 的历史导入豁免在 INSERT 侧是 declared ≠ enforced #6640 narrowing (maintainer 2026-08-08, option 2 + loudness rider) is decided — this is an execution residual, not a re-litigation, hence queue not decision box. PR fix(metadata-protocol,spec): preserveAudit is UPDATE-only — narrow the contract and warn loudly on a non-system INSERT (#6640) #6823 is an open draft; until it merges, the canonical security.mdx callout wording this card should reuse does not exist on main — the block is real, selection should skip until fix(metadata-protocol,spec): preserveAudit is UPDATE-only — narrow the contract and warn loudly on a non-system INSERT (#6640) #6823 merges.
• Routing rationale: the principal fix lands in content/docs/** (hand-written protocol page) — devx row of the domain table. Deliberate scope note: the optional second half (adding a .describe() to ExecutionContextSchema.preserveAudit) is domain:spec-surface territory (text-only, acceptance byte-identical, triggers a docs regeneration ride) — if pursued, it should go through the spec-surface seat's sweep pipeline rather than riding this docs card; noted here so the split is a decision, not an accident.
• Dedupe: [观察] stripReadonlyForInsert 完全不读 preserveAudit —— readonly 的历史导入豁免在 INSERT 侧是 declared ≠ enforced #6640 (parent, dispatched, domain:metadata) deliberately excluded this file from its surface — this card exists because of that exclusion, cross-linked, not a duplicate. No other open card or PR touches the state-machine.mdx bullet.
• Stale-premise: checked at the current ref after PR fix(metadata-protocol,spec): preserveAudit is UPDATE-only — narrow the contract and warn loudly on a non-system INSERT (#6640) #6823's latest push; premise holds (PR unmerged, both anchors live).

认领：会话 session_01F8q5J1MQyocgtNspb15fSn，分支 claude/issue-6827-state-machine-preserveaudit-doc。

前置块已解除：PR #6823（#6640）已于 2026-08-08T23:55:06Z 合入 main，security.mdx 的收窄措辞现已落地，本卡可以按同一口径改写 state-machine.mdx:113。开始按卡面核对 update / create 两半的实际代码行为。
