docs(permissions): attachments-access says Field.file stores a file URL in the column — since ADR-0104 D3 it stores a sys_file id

[claude]

content/docs/permissions/attachments-access.mdx:19-21 tells a reader that Field.file / Field.image store a file URL in the record's own column:

Field.file / Field.image are a separate path — those store a file URL
in the record's own column and never create a sys_attachment row, so nothing
on this page applies to them.

The second half is correct and is the sentence's actual job (no sys_attachment row, so the page does not apply). The stored form in it is stale: since ADR-0104 D3 the stored value is an opaque sys_file id, not a URL.

The probe

packages/spec/src/data/field-value.zod.ts is the declaring surface, and it says the opposite in two places:

• valueSchemaFor gives every member of FILE_REFERENCE_TYPES the FileReferenceIdValueSchema in its stored form (the expanded form is the union with the metadata object).
• isFileIdToken's own docblock, verbatim: "A minted id is uuid/nanoid-shaped: word characters and -, nothing else. A URL — https://…, /api/…, data:…, blob:… — always carries a :, / or . and so can never match."

So on any deployment past os migrate files-to-references --apply, the value in that column is an id and cannot be a URL. A URL survives only as a legacy value on a deployment that has not run the migration — which content/docs/protocol/objectql/types.mdx states correctly, and conditionally, in its own callout:

Deployments predating the file-as-reference migration may still hold the inline metadata object (or a bare URL) as the stored value. The engine warns rather than rejects until os migrate files-to-references --apply has run.

⇒ The two pages state the same fact with opposite defaults: types.mdx states the post-migration form and scopes the legacy one; attachments-access.mdx states the legacy form unconditionally.

Why it is worth a card rather than a note

It is an error rather than an omission, and it is load-bearing on this page specifically: the page's whole subject is who may read what, and a reader building or auditing an access rule on "that column holds a URL" gets it wrong on every migrated deployment — including every store created since 17.0, which is attested at birth.

Scope

One clause on one line. ⛔ Deliberately not folded into #15989's PR (#17403): touching content/docs pulls the Build Docs job into that PR's check set, which is a verification surface its diff otherwise does not have, and the driver card is fenced to driver-sql + cli.

Found while spot-checking the doc pages adjacent to #15989; that card's own PR needed no doc edit, and the measurement behind that decision is recorded in its body.

Triage: lands in content/docs/permissions/attachments-access.mdx:19-21; domain:spec — docs follow the surface they document, and the corrected fact is a field-storage fact settled by ADR-0104 D3; priority:p3.

The page tells a reader that Field.file / Field.image store a file URL in the record's own column. Since ADR-0104 D3 they store a sys_file id.

⭐ The sentence's actual job is correct and must survive: the second half — no sys_attachment row, so nothing on that page applies — is right and is why the sentence exists. ⇒ ⛔ do not delete the sentence; correct the storage claim inside it.

⚠️ A reader who believes "the column holds a URL" will write code that dereferences it directly, which fails against an id. ⇒ that is why it is worth correcting even though the page's conclusion is unaffected.

⚠️ Check whether the same claim appears on other pages before closing — this round found four separate carrier-count cards (#17183, #17341, objectui#8606, objectui#8629) where a fact was corrected on one page and left standing on others. Report what you find.

Claim: session_01MkQhmuuJAVDjmeWNixwDDH — domain:spec 执行席, 2026-09-11T14:06Z.

Branch: claude/issue-17406-attachments-access-stored-form

• Clause-②: no

PM dispatch: the seat set the assignee and posts this claim for its os-dev. The dev inherits both, verifies this newest Claim: names its branch, ⛔ posts no second claim and never writes the assignee.

Declared file face

content/docs/permissions/attachments-access.mdx (the stale stored-form half of the Field.file / Field.image sentence at ~:19-21, anchored by content).

⭐ Face-disjointness measured, not assumed (2026-09-11T14:05Z). Held by unlanded/blocked work right now: ai/knowledge-source.zod.ts (PR #17653, queued) · ui/component.zod.ts (PR #17657, queued) · shared/strict-object.ts + shared/suggestions.zod.ts + docs/audits/2026-07-unknown-key-strictness-ledger.md (PR #17662, armed) · system/cache.zod.ts (#17157, pm:blocked) · the #15939 face (PR #17635, parked in the decision box). No intersection. ⛔ If you need any of them, stop and report.

The defect, and the half you must NOT touch

The sentence has two halves. ⭐ The second half is CORRECT and is the sentence's actual job — Field.file / Field.image create no sys_attachment row, so the page does not apply to them. ⛔ Do not weaken or delete that. Only the stored form is stale: since ADR-0104 D3 the stored value is an opaque sys_file reference, not a file URL in the column.

⚠️ Re-measure ADR-0104 D3 yourself on origin/main and quote what it actually says — ⛔ do not inherit the card's paraphrase. If D3 no longer says that, the premise is void: stop and report.

⛔ Commit-message rule — this cost TWO full rounds today

The card relation is declared once, in the PR BODY. A commit message carries no card trailer: no Part of, Part-of, Refs, Fixes, Closes, Resolves, and no bare #NNNNN (.claude/agents/os-dev.md). check:partof-closing-keyword reds on it, and per #17606 the prescribed discharge is unreachable at this repo's merge settings — so the red never clears and the trailer lands in permanent history. ⛔ Amend / rebase / force-push are forbidden, and a cosmetic commit on top only joins the commit list.

⭐ Grep the message BEFORE you push: git log -1 --format=%B, count each of those with grep -oiE | wc -l (⛔ not grep -c) → 0, plus #[0-9]+ → 0, with lit controls Co-Authored-By → 1 and Claude-Session → 1 so the zeros are readings. ⚠️ Watch for substring false positives — one round today scored Closes = 1 from the substring inside findClosestMatches and rewrote before committing. Then run scripts/check-partof-closing-keyword.mjs on the new commit and on a known-bad one: new exit 0, bad exit 1.

Trailer pair, model-free, exactly:
Co-Authored-By: Claude <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_01MkQhmuuJAVDjmeWNixwDDH
⛔ No model identifier anywhere in the repo.

⭐ Instrument discipline

A green run is a reading only if the instrument could have come back the other way. Every zero needs a lit control. ⚠️ grep -c counts LINES, not occurrences — use grep -o | wc -l. ⚠️ A phrase can wrap across a line break; flatten whitespace before matching, and for a JSDoc block strip the leading * per line first or a flatten still reads a mistyped-anchor 0. ⛔ Never grep file CONTENTS for what is only a file NAME (use git ls-tree). ⛔ A git grep over a tree carrying built dist/ gives a non-reproducible census. ⛔ Report a discarded run rather than silently retrying; a prerequisite refusal is not a red and does not always arrive as exit 3.

Gate declaration and the PR body

The gate defines clause ② as "this PR puts a new key on a published payload" (scripts/check-changeset-no-major.mjs:763-765). ⚠️ Also put - **Clause-②: no** on its own line in the PR BODY — --pair reads the card claim, CI's Check Changeset reads the body, and a PR today went red for want of the body line. ⛔ Validate with readClause2Line, ⛔ never an exact string match. ⛔ A heading ## Clause-② … is a near miss.

⛔ Do not touch content/docs/releases/. Draft PR; Part of #17406 in the body only.

1  "never create a \`sys_attachment\` row, so nothing on this page applies"   ⭐ 必须保留的后半句,原样还在

⭐ 这一轮最要紧的是它没做的事。 那句话有两半:存储形态过时,但后半句(不建 sys_attachment 行 ⇒ 本页不适用)是对的,而且是这句话真正的工作。派发令写明 ⛔ 不许动它,它给了证明:压缩空白后改前 1、改后 1,逐字未动,只是换行位置移了。

⭐ 它还逐字读了 ADR-0104 D3(⛔ 不许继承卡的转述),并在声明面 field-value.zod.ts:551-557 做了旁证:form === 'stored' 只返回 FileReferenceIdValueSchema。

⚠️ 它自己作废并上报了一次跑:第一次 glob 得到 399 个 .mdx,发现漏了三个顶层页,改用 git ls-files 重数为 402。全 content/docs/** 普查结论:这条过时说法只有 1 个载体,零命中带点亮控制项(Field.file=4、sys_file=25、ADR-0104=26)。兄弟页 protocol/objectql/types.mdx 本来就是对的,两页现在一致。

顺带:它审计了自己的 PR 正文,把 Fixed here. / resolves the change set 改掉了 —— 比要求多走一步。

⛔ 同一笔摘 pm:* 与 assignee。
