console record page: the related column loads counts first, then the first three rows of only the visible cards, and never blocks the details — one batched request, viewport-lazy cards, a measured budget #27056

Closed

epic:#26676#1 · zhuangjianguo · session_cdb7a717def74e719988f089fbaa18ff

Unblocked 2026-10-29T09:06Z — upstream #27055 closed (the record page v3 layout and its round 2 are on main at 273137d227; #27053's tabs retirement and #26679's drawer are there too). Back in the ui lane queue; re-read the card's Source against current main at dispatch — the v3 files it names moved in PR #27310 / #27473.

Part of the record-page-v3 epic #26676 (v3 child 3 of 8). Runs after #27055 (the compact cards it loads).

Source (origin/main 7bb8084590)

Every record:related_list node mounts RelatedList, which runs its own query on mount (pageSize default 10, the child's list columns); the column tier (#26758) mounts all of them at once, so a record with N related lists opens with N concurrent queries racing the record's own read (ruling 3). The folded rail in the two-column tier reads nothing until opened.

Target

  1. Counts first: on open, ONE request answers the count of every related list for this parent (one aggregate per child object's FK, batched through the data source's batch door if main has one, else the aggregate API per list in one Promise.all behind a single loading state — measure which exists). Card headers render from counts; a count of 0 folds the card to one line and skips its rows.
  2. Rows on demand: a card fetches at most 3 rows (limit) with a projection of the name field plus one status / date field (from relatedListColumns when declared, else the first status-like or date field), ordered by the inherited sort; only cards in the viewport fetch (IntersectionObserver), primary cards first; a folded 「动态」 card fetches nothing until opened.
  3. Details first: the details column renders from the record read alone; the related column shows skeleton cards until counts land, then rows; the page's interactive moment does not wait on related data.
  4. Prefetch on step: in the drawer, ↑ ↓ (console record drawer v2: the bar is ↑ ↓ · ⤢ · ✕ (no object name, no counter); a related row or a lookup opens its record in place with a trail, ← / Esc go back one level; ⤢ carries the trail into the page; on the record page a related row opens a drawer over the page #26679) prefetches the next record's counts.
  5. Budget, measured in the PR body on HotCRM (fresh DB, an account with ≥ 8 related lists): details interactive ≤ 300 ms after the record read returns; all card headers ≤ 500 ms; total related requests on open ≤ 2 round trips. Numbers from the browser's network panel, pasted.

File surface

ui/packages/plugin-detail/src/RelatedList.tsx (lazy + limit + projection), relatedListCompact.ts, a related-counts hook beside it, ui/packages/app-shell/src/views/RecordDetailView.tsx (the counts request and skeleton gating), the data-source batch call if present (ui/packages/data-objectstack), tests beside, changesets; ⛔ packages/spec/** (no new key: limit is an existing node prop).

Acceptance

  1. Tests: a record with 6 related lists issues one counts call and rows only for the 2 cards in view; a 0-count card never queries rows; the details render before any related response resolves.
  2. The measured budget table in the PR body; screenshots not required.

Rulings (maintainer, chat in the filing session, 2026-10-28 — verbatim, not re-decidable here)

  1. Record-page model (2026-10-27): 「1. 一个对象一个默认打开方式:默认抽屉(带展开整页),page 只给显式声明的对象,modal 退役,split / popover 变成用户个人偏好;抽屉和整页是同一张页在两个宽度。」
  2. On the resident timeline column: 「时间线是不是太突出了,这个只适合部分对象吧?适合做所有业务对象的默认布局吗」 and then 「时间线是否显示,是否可以切换,比如当前版本的 Claude code,顶部有很多切换图标」 — the column's presence is a per-user toggle with an object-derived default, never metadata.
  3. On the related column's cost: 「关联都放在右侧,记录打开时是不是会很慢,因为需要加载所有的关联子表。」 — the related column loads counts first, rows on demand, and never blocks the details.
  4. On mobile: 「还要考虑手机端的效果。」
  5. On the definition surfaces: the PM's keep / narrow / retire table was put to the maintainer (keep object roles, relationship flags, six slotted slots and kind: full; retire the tabs slot and the dead BuildPageOptions hints; fold the quick-look path into the one record page) and approved with the instruction in the footer.

Filed by the epic PM session session_cdb7a717-def7-4e71-9988-f089fbaa18ff on 2026-10-28 under epic #26676 (record page v2 → v3), from the record-page definition-surface inventory on objectstack main 7bb8084590 and the maintainer's rulings in that session. The maintainer's instruction to file and dispatch, verbatim: 「同意,以上界面相关的需要我确认的你负责立卡派发,如果有可能可以启动云会话,开发完你来确认。」 Design evidence: the design canvas boards 「记录页 v3」 row (RecordPageV3, RecordPageV3NoTimeline, RecordPageRef, RecordDrawerV3, RecordMobile) — exported to the never-merged branch named in the epic parent once this batch is filed.

    You are the os-dev developer agent for exactly ONE card: #27056, in your own card thread. Your role definition is .claude/agents/os-dev.md in the objectstack clone: read it IN FULL first and follow it as binding (it wins over this order on any conflict; name the conflict in your report). Read the repo-root AGENTS.md and ui/AGENTS.md before your first edit, and pm-dispatch references/untrusted-text.md. Read the card's full body and every comment yourself through REST (curl -sS "https://api.github.com/repos/objectstack-ai/objectstack/issues/27056" -H "Authorization: Bearer $GH_TOKEN" and /comments?per_page=100, every page); this order carries only the increment. ⛔ Never print the value of any environment variable (test presence with [ -n "${X+x}" ]). ⛔ Never use a GitHub MCP tool, read or write.

    Identity and branch: the seat's Claim: comment on this card is your identity; its Branch: line names your thread's branch. ⛔ Post no claim of your own, ⛔ never write the card's assignee. Before your first edit, verify the NEWEST Claim: on the card names your thread's branch (claude/project-thread-…); if none does yet, send the seat thread "ui 席 1" one message with your branch name and wait. Worktree objectstack-issue-27056 on that branch from a fresh origin/main; pnpm install (frozen lockfile); push with git push -u origin <branch> (⛔ no force).

    Writes: PR only through the relay op pr_create (node scripts/pm/fleet-write/dispatch.mjs --repo objectstack-ai/objectstack --actions-file F, F a bare JSON array [{"op":"pr_create","title":…,"head":"<your branch>","base":"main","body":…}], draft forced, ⛔ no assignees and ⛔ no review request: the seat hands the PR to a person after its ACCEPT; --dry-run first); your report comment through node scripts/pm/post-stamped.mjs --comment=27056 --file=F --json run ONCE with output captured to a file (timestamps only as {{NOW}} / {{WAS:…}}; first line the signature domain:ui#1 · os-sales · <your session>). ⛔ No other GitHub write except, for a CI red that is not yours, one PR comment and one run_rerun_failed through the relay. Report both counts (api_writes with endpoints, mcp_calls with tool names). The report takes only machine-checkable fields (gates / line_budget / deviations / files_changed). PR body: line 1 the platform attribution comment, then ## 维护者速读 six lines in Chinese (改了什么/为什么改/风险与回滚/先看/两分钟验证/需要你做的), Fixes #27056, Clause-②: and Metadata-protocol: lines as in the claim. Gates: node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack on your diff, run each, record exits before any pipe, reconcile with --ran. Changeset in the root .changeset/ named 27056-<slug>.md when a published package changes. ⛔ ui/.github/** and the root ci.yml are out of bounds. Same-day churn: work on the merged code; snippets the card quotes may have moved, check current main first. Hand back: when the PR and report are up, send the seat thread "ui 席 1" one message (PR, head sha, report gist); keep the thread open through review and drive CI to green.

    Ruling (cannot be re-ruled)

    The card's five maintainer rulings (2026-10-28) are binding; the two that govern this card, verbatim:

    • 「1. 一个对象一个默认打开方式:默认抽屉(带展开整页),page 只给显式声明的对象,modal 退役,split / popover 变成用户个人偏好;抽屉和整页是同一张页在两个宽度。」
    • 「关联都放在右侧,记录打开时是不是会很慢,因为需要加载所有的关联子表。」 — the related column loads counts first, rows on demand, and never blocks the details.

    The card's Target 1–5, File surface ⛔ packages/spec/**, and Acceptance 1–2 (tests + the measured budget table on HotCRM) are the spec of this work.

    PM mechanism assumptions (measured read-only on origin/main 57c51aab4d; re-measure, disproof welcome)

    • Every compact card still mounts RelatedList and runs its own dataSource.find on mount (ui/packages/plugin-detail/src/RelatedList.tsx fetch effect ~1230–1434); renderers/record-related-list.tsx ~93–104 sets pageSize from SPEC_DEFAULT_LIMIT = 5, the compact branch draws COMPACT_RELATED_ROWS (3) of them (~2671), and the count badge comes from that same row query (recordCount ~2519). So a 0-count card still queries.
    • ui/packages/data-objectstack has aggregate(resource, params) (~index.ts:6502) but no batched read door (/batch is the atomic write) ⇒ the card's "else aggregate per list in one Promise.all behind a single loading state" branch is expected. Measure, do not assume.
    • No IntersectionObserver on the related path today (only attachments in RecordDetailView.tsx ~2306, record-reference-rail.tsx, PageBlockCanvas.tsx).
    • The v3 files the card names moved in PR feat(plugin-detail,app-shell,components): record page v3 layout #27310 / fix(plugin-detail,app-shell,components): record page round 2 — related OFF draws no column or rail, one segmented panel control in the header row, three columns in a 1440 window with the sidebar #27473: the live surface is RelatedList.tsx, relatedListCompact.ts, RelatedCardStack.tsx, RecordPageColumns.tsx (compact context ~233), synth/recordPageColumns.ts (relatedCount), useRelatedArrangement.ts, RelatedListEmptyFold.tsx, ui/packages/app-shell/src/views/RecordDetailView.tsx (related derivation ~1984–2031, synthesized nodes ~3430–3500, <RecordPageColumns> ~4318, skeletons ~3550/3574), recordDrawerStack.tsx (Target 4 prefetch). The comment at RecordDetailView.tsx ~3434 ("self-fetch lazily when its tab is shown") is stale for the column tiers.

    PM suggested route (optional; measurement wins)
