Seam: one request opens a record — a record-page payload (record + related counts and first rows + field access + lock) and an app-scoped metadata bundle, so a record open is 2–3 requests instead of 23–45 serialized in three stages

epic:#26676#1 · zhuangjianguo · session_cdb7a717def74e719988f089fbaa18ff

Filed from the record-page epic #26676 as a sub-issue after the maintainer's 「别人的界面很丝滑，但是我们的界面总觉得卡顿，云端更卡」 and the seat's measurement (2026-10-29). Ruling: 「立…B（接缝卡：记录页一次取齐 + 元数据打包）两张卡，p1」. A Seam: card: the producer is the REST surface (packages/rest / plugin-hono-server, the data and metadata routes), the consumer is the console's data layer (ui/packages/data-objectstack) and the record page; the seat that claims it declares both ends. The client-side waste on the same path is #27626.

Measured

Local (console main 273137d227, dev mode, HotCRM on localhost:4001): opening one contact = 45 requests cold / 23 warm, in three serial stages — ① the record (GET /data/crm_contact?populate=…) + security/explain ×2 + approvals/requests; ② after the record arrives (+130 ms of client work): one GET /meta/object/<child> per related object (9 on a contact), field-access ×4, the approvals lock; ③ after the metadata arrives: one GET /data/<child>?top=1&filter=… count probe per related list (10 on a contact) + attachments + the related rows query + the account. Locally each stage is tens of milliseconds; the drawer is visible at 300 ms.

Cloud (huayan.objectos.app, Cloudflare colo ARN, h2, prod bundle 2.2 MB JS in 93 scripts): the same endpoints cost 0.5–1.4 s each when called alone (GET /api/v1/runtime/config, 293 bytes: 555 / 604 / 729 / 1068 / 1377 ms over five sequential calls; GET /meta/app 0.9–1.8 s; GET /meta/view 1.8–3.8 s; no cache-control, no server-timing). The HotCRM contacts list route fired 42 API calls on load, of which auth/me/localization 8.2 s, packages 7.9 s, sys_inbox_message 7.5 s, meta/dashboard 6.1 s, meta/object/sys_user 5.3 s, data/crm_contact 5.3 s — the same calls that take ~1 s alone take 5–8 s when fifteen of them run at once, and the list had not rendered after 50 s. A three-stage, 23-request record open on that path is a multi-second wait by arithmetic alone.

Linear, Attio and Twenty open a record with one aggregated request (counts and permissions ride with the record), load metadata once at boot, and prefetch on hover.

Target

A record-page payload endpoint (shape to be designed by the claiming seat and recorded under packages/spec/contracts/**): GET /api/v1/data/<object>/<id>/page (or a query body) returns in ONE response — the record with its populated lookups; for every related list the console would draw (the inbound lookups, in the object's declared order) the count and the first N rows (N = 3, the compact panel's face) with the related-list columns; the caller's field access for the record; the approval lock state; the record's security verdict (explain) for the actions the header draws. One request, one round trip, one server-side transaction.
An app-scoped metadata bundle: GET /api/v1/meta/app/<appId>/bundle returns the app, its navigation, every object the app's navigation and those objects' inbound relations reach, their views, pages and dashboards, with an ETag; the console loads it once per session and sends If-None-Match after. Today's per-object GET /meta/object/<name> stays for Studio and for objects outside the bundle.
The console consumes both: the record page (split pane, overlay, full page, Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 / Record drawer v4: a bounded peek over the list — md cap instead of the field-count bucket, no dim overlay, the list stays readable and clickable, ⤢ maximizes in place at the same URL; the full page is reached only from the row ↗ and the header ⋯ #27545) opens from the page payload with no second stage; stepping ↓ ↑ prefetches the next and previous records' payloads; the per-related top=1 count probes, the per-open child metadata loads and the separate field-access / lock / explain calls on open retire (startup posture: no dual path kept).
Server-side observability for the cloud reading: the REST layer emits Server-Timing (db, meta, total) on every response, so the next measurement separates origin time from the network path; metadata responses carry Cache-Control + ETag.
Clause-②: yes (new REST routes, declared in the spec contracts); Metadata-protocol: added (the bundle's shape).

File surface

Producer: packages/rest/src/** (routes), packages/plugin-hono-server/** (wiring), packages/spec/contracts/** (the two shapes), packages/objectql only if a batched count query is needed, tests beside, changeset. Consumer: ui/packages/data-objectstack/src/index.ts, ui/packages/app-shell/src/views/RecordDetailView.tsx + recordDrawerStack.tsx (prefetch), ui/packages/plugin-detail/src/renderers/recordBinding.tsx + RelatedCardStack.tsx (counts and rows from the payload), tests beside, changeset.

Acceptance

Contract tests for both shapes; a console test that a record open issues exactly one page-payload request (plus at most one metadata bundle on a cold session) and zero top=1 probes.
The cloud reading re-run by the epic seat on huayan.objectos.app after landing: record open under 1 s warm, list route under 3 s cold, with Server-Timing in the PR body.
The epic seat verifies in the console preview before ACCEPT (maintainer: 「车队开发完后你审核效果」).

Claim correction · 2026-10-31T03:04Z · amends claim 6538102504 (branch claude/project-thread-dd5lh4), append-only

File surface, amended by seat ruling:

Plus packages/cloud-connection/src/runtime-config-plugin.ts and its tests. GET /runtime/config gets a body-hash ETag with private, no-cache, and If-None-Match answers 304. It stays anonymous. The caller is resolved only when X-OS-Debug-Timing is sent, so the existing timing gate can open there.
Plus GET /auth/me/localization (plugin-hono-server, already in surface), which gets the same ETag with private, no-cache.
Both routes are named in the card's cloud reading. The dev's Step 1 table (58 routes on main 69ce01d) is the premise.

File surface, amended by seat ruling: also packages/client (meta.getAppBundle(appId)), so the route ledger row takes disposition sdk. PR 1's data.recordPage is the precedent. PR: #28287 (draft, Part of #27627). Shape: packages/spec/src/api/app-bundle.zod.ts AppMetadataBundleResponseSchema.

Claim correction · 2026-10-31T03:11Z · amends claim 6538102504 (branch claude/project-thread-dd5lh4), append-only

File surface, amended by seat ruling. Both additions are forced by the dependency graph, and the PR body should name both:

packages/types/src/representation-validator.ts (new), plus one export line in packages/types/src/index.ts. This is the one copy of the body-hash ETag / If-None-Match rule. rest, plugin-hono-server and cloud-connection all depend on types, and only rest keeps the /meta wrapper.
packages/cloud-connection/package.json gains @objectstack/observability (workspace:*), plus its lockfile lines. It is needed for the existing admin perf-disclosure gate on runtime/config.

Claim amendment (same console-half claim, same branch claude/project-thread-xoio4p, PR #28321) · 2026-10-31T10:02Z

Producer PR feat(rest): one request loads an app's metadata — GET /meta/app/{appId}/bundle, per caller, with an ETag #28287 (PR 2) merged as 8441a01277, which clears the consumer-after-producer constraint.
Closing keyword: PR feat(console): entering an app loads its metadata bundle once, and a record open reads no metadata #28321 is the last open part of Seam: one request opens a record — a record-page payload (record + related counts and first rows + field access + lock) and an app-scoped metadata bundle, so a record open is 2–3 requests instead of 23–45 serialized in three stages #27627, so its body changes from Part of #27627 to Fixes #27627 (spec seat 1 agreed; the card stays open until feat(console): entering an app loads its metadata bundle once, and a record open reads no metadata #28321 merges).
Owed before ACCEPT: merge origin/main, switch to the conditional getAppBundle(appId, { ifNoneMatch }), and bind the spec type AppMetadataBundleResponseSchema (name approved by the maintainer). Clause-② is re-measured on the built declarations after the type binding.

Console half of #27627, final pass: draft #28321, head 07e67218, reported 2026-10-31T10:58Z. Producer #28287 is on main; the PR body now says Fixes #27627 (claim amendment 6541997127). Supersedes report 6539052883.

Claim amendment (same console-half claim, same branch claude/project-thread-xoio4p, PR #28321 head 07e67218) · 2026-10-31T10:59Z

Clause-②: yes (widening) — re-measured by the dev on the built declarations after binding AppMetadataBundleResponse, replacing the claim's no: the exported ObjectStack adapter of @object-ui/data-objectstack gains one public member, loadAppBundle(appId: string): Promise<void>; app-shell's declarations add nothing. The PR owes a contract review at TIER_DEFAULT; it carries needs:contract-review.
Metadata-protocol: none (unchanged); changeset stays patch. Closing keyword stays Fixes #27627 (amendment 6541997127).
Dev report 6542507828 supersedes 6539052883 (its relay: 6 reads 5).

Landed — console half (PR 3, last part) · 2026-10-31T14:46Z

reading	value
PR #28321	merged through the merge queue at 2026-10-31T14:45:11Z, head `07e67218` (PASS 6542690057, ACCEPT 6542699351), merge commit `a9f1452192`; after producer #28287 (`8441a01277`)
landing go	the maintainer, 2026-10-31T14:22Z in the ui seat 2 thread: 「使用 pm-dispatch 技能审核和落地pr」
`origin/main`	contains `a9f1452192` (`git merge-base --is-ancestor`)

Delivered: entering an app loads its metadata bundle once (conditional on the weak ETag); a warm record open reads no metadata, a cold one adds one bundle request in the page's first wave. Card closed by Fixes; pm:dispatched removed. Not owed before landing, recorded per the contract review's boundary flag: one live open on a cloud box when a seat next has one.

Ruled: keep the Server-Timing gate · 2026-10-31T15:13Z

The maintainer said 「同意」 at 2026-10-31T15:10Z. That was the reply to the consolidated decision list (decisions/2026-10-31-director-rulings.md, item 8, recommendation 保持), which he accepted in full as recommended. It answers the seat's question of 2026-10-31T02:56Z.

Server-Timing keeps being sent only when OS_SERVER_TIMING=true is set, or when an admin caller sends X-OS-Debug-Timing. It is not opened to every caller. That is the behaviour PR #28320 shipped, so nothing more is owed on this card.
