[maintainer] refactor(ui): split ObjectGrid.tsx (7641 lines) into smaller modules, one move-only slice per PR, so concurrent ui cards stop colliding in it

Filing gate ③: a task the maintainer dispatched, quoted below. Filed by seat domain:ui#1 (seat post #25966) · os-steve · session session_017iXjUm1rujwDk7f3KT1Pkk. ⛔ Not a claim.

The maintainer's words, verbatim (ui-lane project, 2026-10-26): 「大文件互踩：立重构卡把 ObjectView 和 ObjectGrid 拆成小模块。这个可以立卡」

Business reason. ③, the words above. The ui lane now runs up to ten card threads at once, and two seats. ui/packages/plugin-grid/src/ObjectGrid.tsx is one file that many unrelated cards must edit, so the seat has to queue those cards serially by region. That holds whole cards back and causes text conflicts at merge. Smaller modules let two cards that touch different concerns run and land in parallel.

Reader who acts: the ui lane seat that owns @object-ui/plugin-grid, one dispatch per slice. The first act is a fresh seam table measured at claim.

Measured (on `origin/main` `05f7758f`, 2026-10-26)

7641 lines. Lines 1–1717 are module-level helpers, types and constants. The component starts at line 1718 and runs to the end of the file.
In flight in this file today: fix(plugin-grid): order a grouped grid's groups by the level's orderBy #25977 (server grouping key, in the merge queue), fix(plugin-list,plugin-grid): list empty state tells no-access and "mine" apart from no records #25987 (default empty state, under review). Re-measure at claim, because the file moves daily.

The ask

Split along the existing seams, one area per PR, each slice move-only: no logic change, no renamed identifier, and no change to behaviour or to the rendered DOM.
The package's public surface does not move. Every name @object-ui/plugin-grid exports from this file today stays importable from the same entry point. The file itself remains, as the component plus re-exports, so imports by path keep resolving.
Tests stay as they are. The only test edits allowed are import or vi.mock path updates that the move forces, each listed in the PR body. The package's whole test suite is green before and after each slice.
Order. Start with the module-level helpers (lines 1–1717): pure functions, types and constants that need no shared state. Split the component body only after that, by concern (hooks or sub-components). Where moved code needs component state, pass it explicitly. ⛔ No second copy of a helper, ⛔ no re-derivation.
One slice in flight at a time, and each lands before the next is dispatched. The card stays open across slices (Part of #N); the last slice closes it.

Dispatch constraint while this card is open

While a slice is in flight, no other card edits ui/packages/plugin-grid/src/ObjectGrid.tsx. Before a slice is dispatched, the in-flight cards in this file land first. The seat runs this as a serial constraint on its seat post.
⛔ ui/.github/** and the root ci.yml are out of bounds for now (maintainer's word, ui-merge epic in flight). The changeset goes in the root .changeset/.

Duplicate check

search_issues on objectstack-ai/objectstack, "split ObjectView.tsx ObjectGrid.tsx into smaller modules refactor large file": 4 hits, none for this file. Shape follows #25522 (engine.ts, move-only slices) and #24586.

Triage: first grade — `tech-debt` · `priority:p2` · `domain:ui` · `area:devpath` · `pm:queue` · triage seat · `session_01AavokzJ5DndAwitDXvKy4U` · 2026-10-26T08:58Z

⛔ Not a claim, ⛔ not a dispatch.

p2: the maintainer's 「大文件互踩：立重构卡…」. ObjectGrid.tsx (7,641 lines) serializes unrelated ui cards. Each slice is move-only, one per PR, with no behaviour change, and lands between the in-flight cards that touch the same regions. The seat orders the slices against its queue.

You are the os-dev developer agent for exactly ONE card: #25994, 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/25994" -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.

Hand back: when the PR and report are up, send the seat thread "Dispatch the ui lane" one message (PR, head sha, report gist); keep the thread open through review.

Ruling (cannot be re-ruled)

The card is a maintainer-dispatched task, verbatim: 「大文件互踩：立重构卡把 ObjectView 和 ObjectGrid 拆成小模块。这个可以立卡」. The card body's "The ask" 1–5 binds: move-only, public surface unchanged, tests unchanged except forced import/vi.mock path updates each listed in the body, one slice in flight at a time.

Scope: slice 7 only (C + D + E), `Part of #25994`

Plan and traps: the hand-off 6438136564 (method, traps 1–5, the slice 7 notes) and the seam table in #26364 / re-plan in #26499. File surface: ui/packages/plugin-grid/src/ObjectGrid.tsx + new sibling objectGrid*.ts module(s) for C, D, E + the test files whose source pins must re-point (gridNonAuthorKeys.test.tsx reads both files; keep the NON-AUTHOR SURFACE — \columnState`block adjacent to thecolumnStateseed in the new module). Move proof in the body: base non-blank-line multiset = newObjectGrid.tsx` + modules. ⛔ Slice 8 (R + U + V) is not in this dispatch.

PM mechanism assumptions (measure)

ObjectGrid.tsx is 5250 lines on origin/main 1685a06d; last touch refactor(plugin-grid): move ObjectGrid's grouping and column summaries into sibling hooks (slice 6) #26574 (slice 6). No open PR touches ui/packages/plugin-grid/src/** source (scan of the 18 open PRs at this order; chore(deps)(deps-dev): bump the development-dependencies group across 1 directory with 22 updates #26556 touches only plugin-grid/package.json). Re-check at your first fetch.

Tier

No path-derived mandate (dispatch-gates --tier). TIER_DEFAULT, effort high (M-size move-only slice; judgment is in the seams, the gates judge the move). Not Tier H: the seat lands it after its own review.

Landed slice 7 · dispatch order slice 8 · `domain:ui#1` · `session_01JQwxbZeBv2y91towxasSUT` · 2026-10-27T15:55Z

Landed: PR #26773 (slice 7: regions C, D, E) merged as 7bdff7ec5a; ObjectGrid.tsx is 5160 lines on origin/main 7bdff7ec. The seat's record is PR #26773 comment 6446241415. The claim carries on to the last slice; a new Claim: names the branch.

Slice 8 (R + U + V), Fixes #25994 — to the same card thread (session_01JQwxbXqCPeUA7ztE9YWKwP), which holds the method. Everything in the slice 7 order 6444517014 stands (role file, writes, identity, gates, move-only, the maintainer's words), with these increments:

Scope: regions R, U, V per the seam table (refactor(plugin-grid): move ObjectGrid's authored-input diagnostics into a sibling hook (slice 3) #26364), the re-plan (refactor(plugin-grid): move ObjectGrid's query inputs and grouping decisions into sibling hooks (slice 4) #26499) and the slice 8 notes in hand-off 6438136564. File surface: ui/packages/plugin-grid/src/ObjectGrid.tsx + new sibling objectGrid*.ts module(s) + the test files whose source pins must re-point.
Pins named in 6438136564 to re-point, not weaken: columnReadBoundary-6458 (the slice between '(cols as ListColumn[])' and '// String array format - enrich with objectDef field metadata' must read the new module), cellRendererResolutionBoundary-8920 (no direct resolver call in ObjectGrid.tsx), relationalMetaCopySet.derivation (the single renderCellEditor: property, 4-space indent, in AA), column-identity.ratchet (its CONVERGED path must follow columnIdentity( into generateColumns's new home), percent-storage-callers-11475 (formatPercent stays in the mobile card, AC).
This slice closes the card: the PR body says Fixes #25994, with the slice table summarising slices 1–8 and the final line count.
Branch: start from a fresh origin/main (7bdff7ec or later). If your thread's branch still exists on the remote at the merged head, merge origin/main into it (⛔ no force-push); report the branch you push to the seat thread before the first edit and wait for the new Claim:.
Tier: TIER_DEFAULT, effort high; not Tier H.

Slice 8 (regions R, U, V) merged as PR #26806 (f79ec28949, seat record: PR comment 6448400455), which closed this card. All eight slices are in: ObjectGrid.tsx went from 7,689 to 3,962 lines, with 19 sibling modules; every slice was move-only, and the plugin-grid suite matched before and after each one. pm:dispatched is removed with the close. Nothing is left on this card.
