data table: auto column width is estimated from the raw value, so formatted currency truncates beside free space and the Progress percentage hides under the sticky Actions column

Path: ② the capabilities an end user meets in the app — list views | 缺项 | P2

Split by the triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U from objectui#11672 (the 2026-10-06 console dogfood sweep, showcase, framework ce577ec4), items 10 (width) and 12. Re-read on objectui main (848ba0e12f) before filing: still live, with no open duplicate. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/components/src/renderers/complex/data-table.tsx (the width estimate about :1003; maxWidth and truncate about :2674 and :2910) ⇒ domain:ui; rationale: the width is sized from the stored value, not from the rendered text.

What happens

On Projects → All Projects, Budget shows "200,000…." with spare width in the row, and the same happens on the CRM Workbench. On Tasks at 1440 px, the Progress percentage (stored 0.45) is clipped under the sticky Actions column.

Done when

Auto width is estimated from the formatted cell text: currency, percent and so on.
A sticky column never covers a cell's content.
Pins: the measured Budget and Progress cells render whole at 1440 px.

Domain: domain:ui
Seat: domain:ui#2
File surface: packages/components/src/renderers/complex/data-table.tsx: the auto-width estimate (about :985–:1010), the cell maxWidth / truncate sites (about :2603–:2680, :2910), and the right-pinned sticky column (about :2300–:2310); whatever already formats a cell's display text for that table, only as much as the estimate needs to read it (the column's formatter, or the field-type display formatter the list view hands the table); the tests beside them; and .changeset/11682-*.md (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: opus (dispatch-gates --tier --repo objectstack-ai/objectui: no path-derived mandate; default tier)
Clause-②: no
Thread-read: none
Serial constraints cleared: none blocking. No open PR touches data-table.tsx (objectui#11713, #11715, #11716, #11069 and the release PR objectui#11600 were read). This seat's in-flight objectui#11680 is on components' renderers/placeholders.tsx and core's registry, a different file in the same package; that is ordinary concurrency, and the later lander merges. objectui#11681 is on plugin-charts. Read 2026-10-06T12:55Z.

Why Clause-②: no: the fix sizes a column from the text its cells draw, and keeps a sticky column off a cell's content. That changes what a published table renders, and widens no accepted input and adds no export. If the formatted text cannot be read without a new column or schema key (for example an authored width-estimate hook), that is a widening. The dev stops and reports needs_decision with the four-axis frame rather than adding the key.

Measured live on the showcase at 1440px (content box 1184px): Budget truncated because 200000 sized 96px for a drawn 150,000.00 needing 72.61px, and Progress sat 33px under the right-pinned Actions column because OTHER columns were over-estimated (Assignee 240px for 171px, a lookup object stringified to 15 chars), so the table was 1230px; after: both lists fit 1184px, 0 clipped cells and 0 cells under the last column on Projects, Tasks and CRM Workbench. Also fixed in the same file: two right-pinned columns both stuck at right-0 (an author pinned:right beside Actions was drawn under it); each now sticks at the measured width of the pinned cells after it, mirroring measuredStickyLefts.

domain:ui execution seat 2 · session_01FngvPpdrnhHMdHHq6vwwju (os-justin) · 2026-10-06T15:30Z. Dev report: os-dev-report on this card.

Shape: draft, base main (merge-base 9ca3cac; git merge-tree against main at 7300fca is clean, and the merge queue builds the group), first line Fixes #11682, Clause-②: no at the start of a line. 4 files, +670/−14, all inside the claim's surface. NOT GOVERNED. Nothing is added to the entry.
The measured cause (showcase, 1440px, 1184px content box):
- Budget truncated because 200000 was sized to 96px for a drawn 150,000.00 that needs 72.61px of content.
- Progress sat 33px under the right-pinned Actions column because other columns were over-estimated from stored values, so the Tasks table was 1230px wide. Assignee got 240px for 171px, from a stringified lookup object.
- The card's "percent stored 0.45" was a progress field stored as 45; the defect was real either way.
Seat's own reading of the diff:
- The auto-width estimate now reads back what each auto-sized column's header and cells drew, in a layout effect. Where the page is laid out it uses the measured natural width plus the measured cell inset. Where it is not, it uses the drawn text length with the old 8px/char rule. The stored value is used only before the first draw.
- The 80px floor, the 400px cap, the header-only masked column, explicit width, fitContent and user-dragged widths are unchanged.
- No second formatter: the cell's own drawn text is the source, as the order required.
- Right-pinned columns each stick at the measured width of the pinned columns after them, mirroring measuredStickyLefts, so an author's right pin beside Actions is no longer drawn under it.
Convergence, checked by the seat (this is the core table, so the read must not feed itself):
- each read compares a signature of the targets' column, text and cell classes, and skips the measurement when it is equal;
- an equal measurement writes no state, so it costs no commit;
- the max-content probe is set and restored inside one task, on elements with no React-managed style;
- the MutationObserver watches text and nodes only, so the probe's attribute writes are invisible to it;
- the ResizeObserver re-read is deduped by the same signature, and a read with no layout is not remembered;
- reads are skipped while a cell is edited.
Recorded, not blocking: the signature walk (querySelectorAll plus textContent over the drawn page) runs after every render of the table. It reads no layout, so it forces no reflow. A very large page pays it per render.
The dev's open question (a table wider than its container): A. At scroll 0, a sticky pinned column overlays the scrolling column passing beneath it. That is what pinning means, and every cell is reachable, with none covered at the scroll end. The measured lists now fit, and stacked pins no longer cover each other. A separate pinned pane would be an unpulled layout rewrite.
Changeset (@object-ui/components: patch), checked sentence by sentence against the diff:
- the Auto width paragraph: the drawn-text source, the laid-out and text-only paths, the unchanged floor, cap, masked, explicit and fitContent widths, and the width following the drawn rows;
- the Right-pinned paragraph;
- "Nothing is added to the package entry".
patch fits.
Tests and gates (dev, measured):
- packages/components/ + packages/plugin-grid/: 547 files, 5403 tests;
- type-check (both programs), build and lint: 0 errors;
- the new pins: arithmetic on the text path, replayed Chromium geometry for Budget and Tasks, mocked stacked pins;
- the 10657 masked control re-judged (it pinned the removed stored-value branch);
- the live one-time reading on Projects / Tasks / CRM Workbench: 0 clipped cells and 0 covered cells after, against 3 Budget clipped and 10 Progress covered before;
- one ablation leg (setDrawnSizes voided) went exactly 6 red / 12 green and was restored by blob. It ran outside the lock at --maxWorkers=1 after 3 queue timeouts, which is declared.
Raised to the maintainer, not redone by the seat: the dev's PR-assignee write (label-write --assign os-justin on objectui#11725) was refused by its session's permission classifier before it ran. It was not retried, and the seat does not redo a refused write under another identity. It joins the two already raised (objectui#11702, objectui#11710).
Out-of-scope, Acceptance note, not filed: the showcase's "Budget Remaining" formula over two currency fields draws an ungrouped monospace 90000. This is an observation, with no contract cited.
CI on 3341132: in progress at this read (28 success, 3 skipped, 11 running, 0 failed).

The merge. Squash 7a2c60b went through the merge queue, with one parent, 9cf08d9 (objectui#11724, landed just before it), and is an ancestor of origin/main. 4 files, +670/−14. Its diff against the parent is byte-identical to the PR's net diff at 3341132 (md5 5e339fec… on both). Clause-②: no, so no contract review was owed (ACCEPT 6019679369).
Content check against the first parent:

reading 9cf08d9 7a2c60b

function measureDrawnColumnSizes in data-table.tsx (the drawn-width read) 0 1

__tests__/data-table-drawn-width-11682.test.tsx present 0 1

The stored-value length line stays, as the changeset says: the stored value is read only before the first draw.
Closures. Fixes #11682 closed this card as completed at the merge. No other issue closed in the landing window. pm:dispatched comes off in this stroke.
Still raised to the maintainer: the PR assignee on objectui#11725 is unset. The dev's label-write --assign was refused by its session's permission classifier, and the seat does not redo it under another identity.
Recorded, not filed:
- a sticky pinned column overlays the scrolling column beneath it on a table wider than its container. That is pinning by design (the seat's call A).
- the per-render signature walk is recorded in the ACCEPT.
- the showcase's "Budget Remaining" formula draws an ungrouped monospace number.
