Record "server enforces, client is courtesy" as a real ADR decision — ~30 in-repo sites plus 9 in objectui cite it, and no ADR decides it

[os-steve]

Split out of #9255 (that card's retarget half). This card is the part a dev seat may not do: authoring an ADR entry. docs/adr/** is maintainer-authored, so the #9255 implementation stopped at the traceability half and left the decision itself unrecorded.

What the corpus search found (measured at 14935ab71, whole docs/adr/ corpus, 127 records)

The rule is real and universally practised; no ADR decides it. Searched by content, not by number — courtesy, server enforces, server is the authority, client is a courtesy, enforcement point, fail-closed, UI absence, plus every decision heading matching server|client|enforc|authorit.

Candidate	What it actually decides	Is it the rule?
0057-erp-authorization-core-business-units-and-scope-depth.md D10 (:422)	Setup-nav surfacing follows the capability (ADR-0029 K2); the object stays open	No — nav-entry tiering
same file, PS-2 implementation note (2026-06-22, :516) — "D10 realized via server-enforced requiresService"	The Setup nav is filtered server-side in filterAppForUser; requiresObject is "a client-side (objectui) gate, not enforced in this repo"	Closest ancestor — but scoped to nav/app-metadata visibility, not a general enforcement-location rule
0057-system-data-lifecycle-and-retention.md	Lifecycle/retention; uses §3.1–3.6, zero D<n> headings	No
ADR-0049 (no unenforced security properties)	Whether a declared property is enforced (declared = enforced, no silent fail-open)	No — different axis (whether, not where)
ADR-0104 addendum, "the enforcement-point principle" (:398)	Build/validate time vs runtime	No — different axis (when, not where)
ADR-0111 D2 / D6	Management authority enforced in the service, not just the route	Narrow instance, not the general rule

Provenance. The first commit to ever write the string is 2256e9369 — "feat: gate Setup Org/Invitations nav on multi-org, server-side (ADR-0057 D10) (#2150)". So the citation began correct and nav-scoped, and the general principle was back-formed from the PS-2 note's server-vs-client contrast. Every later site inherited the number without the scope.

Why this needs a decision record, not a comment fix

The rule is load-bearing across five packages and both repos, and it is the reason for at least three deliberate behaviours: rule-validator's unbound-root-resolves-to-LOCKED narrowing of ADR-0058 D5, the /me/permissions FLS fold in current-user-endpoints.ts, and RUNNER rule 4 ("both sides of every gate"). Those all rest on a sentence with no recorded decision behind it. #9255's PR converts the assertive citations to attributive phrasing so no reader is sent to a decision that does not say this — that removes the false trail but leaves the rule unanchored.

Proposed disposition (maintainer's to make)

The 2026-08-18 ruling on #9255 already authorized this shape: add a decision entry to 0057-erp-authorization-core-business-units-and-scope-depth.md at the next free number (D13), marked as a retroactive recording of an already-practised rule, whose text is the standing sentence and whose scope is explicitly general (not nav-only). Once it exists, the attributive phrasing landed by #9255 becomes a mechanical retarget to a resolvable anchor.

Two things worth deciding at the same time:

1. Scope wording. The rule as practised covers visibility gates, field locks, FLS maps and route authority. If D13 is written nav-narrow it will be re-generalized by the next citer, which is exactly how this happened.
2. Home. ERP-authorization ADR-0057 is where the lineage sits, but the rule is not ERP-specific. A general enforcement-authority ADR of its own may age better, and would sidestep the 三个 ADR 编号各自指向两个不同的已接受决策(0010 / 0019 / 0057)—— adr-anchors.json 与 328 处代码注释按裸编号引用,无法消歧 #5992 bare-ADR-0057 ambiguity permanently.

Blocking relationship

#9592 (teaching check-adr-anchors to validate that a cited Dk is a real heading of the cited ADR) is pm:blocked on the retarget. That gate cannot go green on these sites until this decision exists — attributive phrasing removes the false anchor but does not give the sites a resolvable one.

Triage: promoted to pm:queue, domain:devx, type Task — this is an execution card, not a new decision. The 2026-08-18 ruling on #9255 already fixed the two things this card floats as open: home = a new decision entry in the ERP-auth ADR (0057-erp-authorization-core-business-units-and-scope-depth.md, next free number D13) and scope = explicitly general (the standing sentence, not nav-narrow). The "standalone ADR may age better" alternative re-opens a ruled point and is not commissioned; the #5992 bare-number ambiguity is mitigated by writing the entry into the ERP-auth file explicitly.

Dispatch constraints:

• Governed surface (docs/adr/**): draft-only PR, never ready/queued/auto-merge — the maintainer's hand-merge is the approval of the D13 wording. The PR body must quote the [finding] ADR-0057 D10 ("server enforces, client is courtesy") names no decision in either ADR-0057 — ~20 sites plus an adr-anchors/ invariant ride the anchor #9255 ruling as provenance.
• Mark the entry as a retroactive recording of an already-practised rule (per the card's own proposal); scope wording covers visibility gates, field locks, FLS maps and route authority.
• Serial constraint: [finding] ADR-0057 D10 ("server enforces, client is courtesy") names no decision in either ADR-0057 — ~20 sites plus an adr-anchors/ invariant ride the anchor #9255's retarget PR is in flight (assignee os-steve) — the D13 entry and the retarget touch disjoint files by design, but confirm before claiming; the retarget's attributive phrasing becomes a mechanical re-anchor once D13 exists.
• Downstream: tooling: check-adr-anchors should verify that a cited ADR-NNNN Dk decision letter is a real heading of the cited ADR #9592 stays pm:blocked until this lands; objectui#5202 has been queued independently on the attributive form and does not wait for this.

⛔ PM escalation — the corpus search is done, and it changes the question the maintainer already answered

Maintainer input needed. Not to re-litigate the 2026-08-18 ruling on #9255, but because that ruling rests on an assumption the search has now falsified.

What the ruling assumed

The ruling authorized a new decision entry on 0057-erp-authorization-core-business-units-and-scope-depth.md, described as:

…whose text is the standing rule, marked as a retroactive recording of an already-practised decision.

That framing makes it a transcription: the decision already exists in practice, write it down, retarget the citations, done. Under that reading the triage seat's summary was right — "the only input needed from you is the anchor's true home; everything after is dispatchable."

What the search found

The dev searched the whole corpus — 127 records, by content rather than by number (courtesy, server enforces, server is the authority, enforcement point, fail-closed, UI absence, plus every decision heading matching server|client|enforc|authorit). No ADR decides the general rule. The nearest candidates and why each falls short:

Candidate	Decides	Is it the rule?
ERP-auth ADR-0057 D10 + PS-2 note	Setup-nav capability gating, realized server-side	Ancestor, nav-scoped
0057-system-data-lifecycle-and-retention.md	Lifecycle/retention; §3.1–3.6, zero D-numbered headings	No
ADR-0049	Whether a declared property is enforced	No — whether, not where
ADR-0104 addendum, "enforcement-point principle"	Build/validate time vs runtime	No — when, not where
ADR-0111 D2/D6	Management authority enforced in the service	Narrow instance

And the lineage is provable, which is the part that matters:

• the first commit ever to write the string is 2256e9369 — "gate Setup Org/Invitations nav on multi-org, server-side (ADR-0057 D10) (feat: gate Setup Org/Invitations nav on multi-org, server-side (ADR-0057 D10) #2150)";
• D10's own PS-2 implementation note (:516) contrasts server-side filterAppForUser filtering against a client-side requiresObject gate, described as "a client-side (objectui) gate, not enforced in this repo";
• that contrast is the seed. Later citers kept the number and dropped the scope.

Why this is not a transcription

The rule as practised is broader than anything ever decided. So writing D13 is not recording an existing decision — it is making one, and the only substantive content is how broadly it is scoped.

That is not a detail. It is the entire failure mode this card exists to fix, and it will repeat: D10 was written nav-scoped and got generalized by inheritance over ~40 in-repo sites. A D13 written nav-narrow will be re-generalized the same way by the next citer. Written too broadly, it retroactively blesses claims nobody evaluated — including in objectui, where 9 live source sites already cite it.

So the input needed is not "the anchor's true home". It is the scope wording, which is a judgement about how much of the platform's enforcement posture you are willing to declare in one line.

The two questions

1. Scope. Is "server enforces, client is courtesy" a general platform invariant (every enforcement decision belongs to the server; any client-side check is advisory), or is it bounded to a named surface set (app/nav metadata visibility, field locks, validation rules) with everything else out of scope until separately decided?
2. Home. The ruling proposed the ERP-authorization ADR-0057. If the answer to (1) is "general platform invariant", that file may be the wrong home — it is an ERP-authorization record, and a general invariant filed there inherits a scope it does not want. A different or new ADR may be right.

Recommended route

C — you author the D-entry directly (it is docs/adr/**, governed, and the content question above is a judgement, not a transcription); a follow-up dev card then does the mechanical retarget of both groups once a resolvable anchor exists.

Route B — a dev seat writes the entry as a draft PR for human merge — is authorized by your ruling and remains available. I am recommending against it only because the corpus search moved this from transcription to authorship. If you would rather a seat draft it for you to edit and merge, say so and I will dispatch it that way; the evidence above is everything a drafter would need.

Already shipped and un-regrettable either way

PR #9655 converted 14 sites across 10 files to attributive phrasing — "the rule the framework cites as ADR-0057 D10" rather than asserting the anchor resolves. That is correct whether or not D13 is ever written, and it follows objectui#3888's precedent under the same uncertainty. It removes the false trail without inventing a destination.

Blocked on this: #9255's retarget half, and #9592 (the check-adr-anchors decision-letter validation) — which cannot land until the known-bad citations have a real anchor, or it goes red on exactly the citations it exists to catch.

Maintainer ruling recorded (2026-08-18, live chat with the triage session session_014v3dpZ2224xgf98dfY4rw4; authorization verbatim: 「其他接受你的建议」, accepting the recommendation presented in that session, restated as the operative ruling).

Ruling: record it as an INDEPENDENT general ADR (new number), not as ADR-0057 D13. Reasons on record: this card's own provenance measurement shows nav-narrow wording gets re-generalized by the next citer — so the scope must be written general (visibility gates, field locks, FLS maps, route authority) from the start; and the bare-ADR-0057 ambiguity (#5992) has already cost once, so the general rule gets a clean home. Content: the standing sentence — the server enforces; client-side gating is a usability courtesy — marked explicitly as a retroactive recording of an already-practised rule, with the lineage note (ADR-0057 PS-2 as the closest ancestor). ADR-0057 gets a one-line pointer at the PS-2 note to the new ADR.

Process: dev drafts the ADR + pointer as a draft-only PR; docs/adr/** is a governed surface — ⛔ human merge only, the merge is the maintainer's review act. After it lands, the #9255 attributive phrasings retarget mechanically and #9592's anchor gate can go green on these sites.

Label: needs-user-decision → pm:queue, domain:devx.
