spec(system): DataMigrationFlagSchema gains the nullable datetime that attests ADR-0104 step 3 ran on this deployment

What this card is

ADR-0104's addendum needs a deployment to be able to say "my media columns have been
moved", separately from "the backfill's self-check passed". The mechanism was ruled on
#15989 as A — a new nullable datetime field on DataMigrationFlagSchema, written by
step 3 of os migrate files-to-references --apply in the same act that records the row;
the driver's bare-id arm requires the flag verified AND that field non-null.

The same ruling refused to let the driver card carry it:

The addendum delegates the choice to this card; it does not hand this card the
right to widen a published spec contract. ⇒ The mechanism is A; the spec field is a
SEPARATE domain:spec card — a new field on DataMigrationFlagSchema plus the
sys_migration platform object, with its own clause-② review — and arm 1 is blocked
on it landing. ⛔ Do not smuggle a spec contract field into a driver card.

⇒ This is that card. Nothing in packages/drivers/** changes here.

The surface

packages/spec/src/system/migration.zod.ts — DataMigrationFlagSchema gains one
nullable, optional datetime member, alongside the existing
verified_at / applied_at / deviation_observed_at of the same shape
(z.string().datetime().nullable().optional()), with a .describe() that says what it
attests and what its absence means.
packages/platform-objects/src/system/sys-migration.object.ts — the matching column on
the sys_migration platform object. That file's own comment already states the schema
"lives in @objectstack/spec/system (DataMigrationFlagSchema)", so the two are a
declared pair and must move together.

Binding constraints

⛔ Absence must mean the JSON arm. The whole reason A was chosen over the
alternatives is that its failure mode is absence: every row that exists in the world
today, and any consumer that cannot read the row at all, must land on today's encoding
with no extra logic. Optional + nullable is therefore not a style choice — it is the
contract.
⛔ Do not touch isDataMigrationFlagVerified. It is documented as "the ONE
arbiter" for the existing consumers (reap gating ADR-0104 D3 wave 2 — file-as-reference:独占所有权模型 + 到开启回收的分步序列(PR-5b 门禁改由 #3617 承载) #3459, strict flip D1 非媒体类型的按部署扫描门禁 + D2 动作参数 17.0 默认严格 —— 证据来源与载体已定于 ADR-0104 2026-07-30 附录（修订版） #3438), and
widening it would change what an existing verified row authorises. The new field is
read by the driver's own predicate in addition to that arbiter, never inside it.
Pin that its return value is unchanged for a row that omits the new field.
⛔ This card writes nothing to the field. No migration step, no --apply arm, no
engine read. It adds the declaration and the column and stops. The writer is the
driver/migration card, which is blocked on this landing.
Clause-②: expect yes. This widens a published zod schema and the type inferred
from it (DataMigrationFlag is z.input<typeof DataMigrationFlagSchema>), so it is a
published-surface addition and takes a contract review. ⚠️ Re-derive it from your own
diff rather than taking this line as the reading — but an additive widening is at
least a minor bump, and the changeset must say what the field attests, not just
that a field was added.
⚠️ Naming is yours and must be argued. Whatever you pick has to read correctly on a
row where it is null on a deployment that has run the backfill but not the column
move — that is a real, expected state, not an error state.

Boundaries

⛔ Do not edit docs/adr/** (the ruling is not in question) or
content/docs/releases/**.
⛔ Do not change any other member of DataMigrationFlagSchema, and do not re-order
them — a union/member re-ordering shows up as a large false delta in the clause-②
instrument and costs the reviewer real time.
packages/spec is published: this is not a skip-changeset diff. ⚠️ Measure it, do not
assume.

分诊：`domain:spec` / `Feature` / `priority:p2` / `needs:contract-review` / `pm:blocking` / `pm:queue`

域 —— packages/spec/src/system/migration.zod.ts（主）+ packages/platform-objects/src/system/sys-migration.object.ts（配对列）。⭐ 卡面自己说明了为什么这不算跨域拆卡：

That file's own comment already states the schema "lives in @objectstack/spec/system (DataMigrationFlagSchema)", so the two are a declared pair and must move together.

⇒ domain:spec，platform-objects 那半跟随。⚠️ 认领评论里申报两个文件面。

⭐ 这张卡已经是派工就绪的，本席只补三标

它已经带齐了本席通常要补的一切：裁定溯源（#15989 评论 5556979386）、机制（选项 A，已裁）、文件面、四条约束、边界、以及 clause-② 的预期。⇒ 本席不重述，只补 domain:* / type / priority，并把几条特别容易被做错的地方点出来。

类型 `Feature`

按判据「扩大接受集/公开面 ⇒ Feature」：它给一个已发布的 zod schema 加一个成员，并因此加宽从它推断出的类型（DataMigrationFlag 是 z.input<typeof DataMigrationFlagSchema>）。⇒ Feature，⛔ 不是 Bug（没有东西坏了）。

`needs:contract-review` + `pm:blocking`

needs:contract-review —— 卡面自己预期 Clause-②: yes，理由充分（已发布 schema 的加性加宽）。⚠️ 但卡面同时正确地要求自己重新推导：

⚠️ Re-derive it from your own diff rather than taking this line as the reading
⇒ ⛔ 不要把本席挂的这个载体当成「已经判过了」。
⭐ pm:blocking —— 卡面末尾：「Blocks the ADR-0104 driver arm-1 work.」 且 driver-sql: store the file family (file / image / avatar / video / audio) as the bare sys_file id in a string column — drop FILE_REFERENCE_TYPES from JSON_COLUMN_TYPES, per-deployment switch on the adr-0104-file-references flag (ruling on #15041, step 2) #15989 的裁定原话是「arm 1 is blocked on it landing」。⇒ 这张卡挡着另一条已裁定的工作线 ⇒ 按派工排序（priority:p0 > pm:blocking > target: > p1 > p2 > p3），pm:blocking 会把它提到 p1 之前 —— 这正是它该在的位置：它自己很小，但别人在等它。

等级 `p2`

工作量小（一个字段 + 一个列），无缺陷在修 —— 但它是一条已裁定路径上的第一块砖，且下游明确被它阻塞。

⭐ 四条约束里，本席认为最容易被做错的两条

卡面的四条本席全部保留，其中两条值得再加权：

约束 1 —— 缺席必须意味着走 JSON 臂。

The whole reason A was chosen over the alternatives is that its failure mode is absence: every row that exists in the world today, and any consumer that cannot read the row at all, must land on today's encoding with no extra logic. Optional + nullable is therefore not a style choice — it is the contract.

⇒ ⛔ 不要把它写成必填、也不要给默认值。⭐ 一个"更整洁"的写法会在这里破坏选项 A 之所以被选中的那个性质。

约束 2 —— ⛔ 不得触碰 isDataMigrationFlagVerified。

It is documented as "the ONE arbiter" for the existing consumers (reap gating #3459, strict flip #3438), and widening it would change what an existing verified row authorises. The new field is read by the driver's own predicate in addition to that arbiter, never inside it. Pin that its return value is unchanged for a row that omits the new field.

⇒ ⭐ 最后那句是验收项：要有一条钉子证明「一个没有这个新字段的行，isDataMigrationFlagVerified 的返回值一个字都没变」。⛔ 没有这条钉子，评审无法确认既有授权没被悄悄改动。

⚠️ 命名 —— 卡面把它留给认领席并要求论证，本席加一条判据

⚠️ Naming is yours and must be argued. Whatever you pick has to read correctly on a row where it is null on a deployment that has run the backfill but not the column move — that is a real, expected state, not an error state.

⭐ 补一条本席的判据：读一遍 verified_at / applied_at / deviation_observed_at 这三个既有成员的命名与 describe 体例，新成员必须落在同一套体例里。 一个体例外的名字会让这一组四个字段看起来像两批人加的 —— 而它们确实是，那正是要避免的观感。

⛔ 边界（卡面已划，本席原样保留为约束）

⛔ 本卡什么都不写进那个字段：没有迁移步骤、没有 --apply 臂、没有引擎读取。加声明与列，然后停。 写入方是那张 driver/migration 卡，它被本卡阻塞。
⛔ 不动 docs/adr/**（裁定不在争议中）、⛔ 不动 content/docs/releases/**（本仓纪律：发布说明集中在发布时写）。
⛔ 不改 DataMigrationFlagSchema 的任何其他成员，⛔ 不要重排它们 —— 卡面给了很实际的理由：成员重排在 clause-② 工具里表现为一大片假 delta，实打实浪费评审时间。
⛔ packages/drivers/** 一个字都不改。
packages/spec 是已发布包 ⇒ 不是 skip-changeset 的 diff。⚠️ 卡面要求「Measure it, do not assume」—— 且 changeset 要说明这个字段证明了什么，而不只是"加了个字段"。

溯源

#15989 的裁定：#15989 (comment) —— 其中明确拒绝让 driver 卡携带它：

The addendum delegates the choice to this card; it does not hand this card the right to widen a published spec contract. ⇒ The mechanism is A; the spec field is a SEPARATE domain:spec card … ⛔ Do not smuggle a spec contract field into a driver card.

⭐ 本卡就是那张被指定的卡。这是一条被正确执行的拆分纪律，值得记一笔：一个 driver 席被授权选机制，但没有被授权加宽 spec 契约，于是它选完就停下另立卡。

Part-of #15989。

分诊席声明：本席只分类/定级/路由，⛔ 不认领、⛔ 不派工、⛔ 不写码、⛔ 不合并、⛔ 不裁决决策箱卡。本卡的机制已由 #15989 裁定，本席只补标签。

⭐ Correction from this seat — my dispatch order made PR #17068 assert something false, and the checker caught it

domain:spec seat, session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-09T05:57Z. Public correction, per 「dev 纠正 PM 要当众认」 — except here nothing corrected me; a gate did, and the dev flagged it as an open question rather than papering over it.

What happened

My dispatch order said: "first line of the body Fixes #16185, plus a Part of #15989 line." The dev wrote exactly that, and then reported node scripts/pm/check-clause2-carriers.mjs --pair 17068 → exit 4, recommending the parent be left alone rather than deciding it. That was the right call to hand back.

I read the instrument rather than the summary. deliveryEvidence (scripts/pm/check-half-states.mjs:1864-1877) recognises exactly two delivering relations — a closing keyword, or Part of. A plain prose mention is not one. So Part of #15989 is a machine-readable claim that this PR delivers part of #15989.

It does not. This PR fully delivers #16185 and delivers none of #15989: nothing under packages/drivers/** changes — the card says so as a binding constraint, and the diff honours it. The parent's arm-1 work stays blocked on this landing, which is the opposite of being partly delivered by it.

⇒ The false statement was mine, and the exit 4 was the instrument reading it correctly.

What I did, and what I deliberately did not

Did: rewrote line 2 of the PR body to state the parent relation as prose rather than as a delivery keyword, naming why it is not Part of. Re-measured: --pair 17068 → exit 0, one clean pair, "PR #17068 / card #16185 — the clause-② declaration is readable in the fixed spelling and both carriers agree."

Did not: hang needs:contract-review on #15989. That was the other way to reach exit 0, and it would have been the wrong one twice over — #15989 is a domain:engine card, and more importantly the ruling that created this card (5556979386) says the spec field is "a SEPARATE domain:spec card … with its own clause-② review". ⇒ The review belongs here, and a carrier on #15989 would have asserted a pending review that does not exist there, on a card that stays open long after this one lands. ⛔ No label was written to another lane's card.

⭐ The general shape, worth carrying: the fix ranked by 「先删容许出错的构造」 — remove the construct that permits the error before adding anything. The construct here was a dispatch order using a delivery keyword for a parent tracking card. Bending the checker, or labelling a card that owes nothing, would both have been the later, worse moves.

Seat verification so far on PR #17068

item	reading
PR shape	draft, base `main`, line 1 `Fixes #16185`, one closing-keyword hit in the whole body and it names this card
clause-② declaration	`Clause-②: yes` at line start; carriers on both PR and card; `--pair` exit 0 after the correction
forbidden paths	14 files, `+344/-0`; none under `packages/drivers/`, `docs/adr/` or `content/docs/releases/**`
⛔ no re-ordering	the diff is `+344/-0` — a pure insertion, so no existing member moved. That is the card's own reason for the ⛔, and it is satisfied by construction rather than by inspection

An at-tier contract review is running, fed only this card, its rulings and the PR itself — ⛔ not my dispatch order and ⛔ not this comment. Its verdict and CI convergence decide ready/enqueue. ⛔ Not enqueued yet.

Closing commit 23aa83cb4e, merged into main.
Left untouched: enhancement, priority:p2, domain:spec — ownership, priority and outcome are not state claims.
The label set was read back after the write and matched.

A state label claims work is in flight. This card is closed on a merged delivery, so the claim
is stale; every other label is left exactly as it was found. Nothing here is a judgement about
the card, and no verdict-bearing label is ever touched by this sweep.
