kanban: every card tells screen-reader users to press Space to pick it up, but the board has no keyboard sensor, so Space starts no drag (and the instructions stay English under zh)

Filing gate ①: a user-visible accessibility defect. reach: a public entry, measured in the browser on the showcase task board (objectstack 66d456d01 examples/app-showcase --fresh, console from objectui PR #12835's branch). Filed by domain:ui seat 3 (session_01Vk15bz8xHtKGUfXfCm16h4) from the os-dev report on objectui#12716, which does not change this. ⛔ Not a claim.

Reader who acts: objectui triage. The landing is packages/plugin-kanban/src/KanbanImpl.tsx (the board's sensors and its DndContext accessibility) and the packages/plugin-kanban/README.md features line.

Measured

Every card's aria-describedby points at dnd-kit's default instructions: "To pick up a draggable item, press the space bar. While dragging, use the arrow keys …".
Space on a focused card starts no drag: the live region does not change, and no card reports aria-pressed.
Under zh the instructions stay English.

Mechanism (read from source)

KanbanImpl.tsx builds useSensors(PointerSensor, TouchSensor) with no KeyboardSensor, and passes no accessibility.screenReaderInstructions.
The package README lists "Accessible: Built on @dnd-kit with keyboard navigation support".

Expected

Either the board supports keyboard drag (a KeyboardSensor, with instructions from the kanban bundle region in all ten packs), or it stops advertising it: no instructions that name a key that does nothing, and a README line that matches. Which one is triage's to grade.

Dedupe (open and closed): every objectui domain:ui card (2433 rows, through #12743) plus the newest objectui issues (from #12741), grepped for KeyboardSensor|screenReaderInstructions|press the space bar and kanban near keyboard: 0 hits. The drag announcements themselves are objectui#12716.

Dedupe words: kanban keyboard drag, KeyboardSensor, screenReaderInstructions, press the space bar kanban.

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015). ⛔ Not a claim, ⛔ not a dispatch.

Why p3: the same grade as its sibling objectui#12716 (p3), the board's other screen-reader defect. The instructions name a key that does nothing; no data is at risk.
Premise read on origin/main: packages/plugin-kanban/src/KanbanImpl.tsx:944 builds useSensors(PointerSensor, TouchSensor) with no KeyboardSensor, and README.md:225 still reads "keyboard navigation support".
The route triage grades (the card leaves it to triage): the truth fix. No instruction names a key that does nothing, and the README line matches what ships. Keyboard drag (a KeyboardSensor and cross-lane coordinates) is a new capability. It is held for the maintainer to name, and this card does not build it.
Serial: the same file as PR fix(plugin-kanban): the board's drag live region names the card and the column, not their ids (objectui#12716) #12835 (objectui#12716, open) and objectui#12838. This card lands after fix(plugin-kanban): the board's drag live region names the card and the column, not their ids (objectui#12716) #12835.

Claim: PM loop round 3 (priority:p3 bug, a11y; filed by domain:ui seat 3 and graded by the triage seat, 6227684358: the truth fix, with keyboard drag held for the maintainer; serial after objectui#12716, which landed as PR #12835)

File surface:

packages/plugin-kanban/src/KanbanImpl.tsx: the board's DndContext accessibility gains screenReaderInstructions.draggable from one bundle sentence, which names no key. The sensors stay PointerSensor and TouchSensor.
packages/plugin-kanban/README.md: the "Accessible" features line (about :225) matches what ships.
packages/i18n/src/locales/*.ts: one key, kanban.dnd.instructions, in all ten packs.
Tests beside the board, and changesets for @object-ui/plugin-kanban and @object-ui/i18n (patch).
⛔ No KeyboardSensor and no keyboard-drag capability. That is a new capability, held for the maintainer by the triage grade. packages/components/src/ui/** stays out.

Stop on breach; explain in the report.
Container & model: S, mode:cloud, model: opus (cloud on the maintainer's stance 「可以的话，ui 后续开发尽量用云 session，并且要求截图给我看」; lane scope on 「你也可以接ui车道的卡」; batch 3 on 「当前任务处理完，后续并发降到3」, this session's chat, 2026-10-16)
Clause-②: yes
Clause-② reason: one new @object-ui/i18n key (kanban.dnd.instructions) in all ten packs. No exported type or prop moves.
Responsibility: n/a — every kanban card tells screen-reader users to press Space, which does nothing, and says it in English under zh
Thread-read: 6227684358
Serial constraints cleared:

objectui#12716 (the board's drag announcements, the same file) landed as PR fix(plugin-kanban): the board's drag live region names the card and the column, not their ids (objectui#12716) #12835 (36e2f7b), and this branch is cut after it.
No open objectui PR touches packages/plugin-kanban/src/** or the README. chore: release packages (next) #11600 touches only a .changeset/pre file of that package. No pm:dispatched objectui claim names the board (read at dispatch).
fix(console,i18n): a settings row's chips read in the session's language (objectui#12821) #12878 (objectui#12821) writes the ten locale packs in the console.settingsView region, not kanban. If it lands first, this branch merges origin/main.
objectui#12838 (the board's English aria-label templates, the same file) waits for this card.

The seat's rulings on the two open questions and on the out-of-scope finding are in the ACCEPT on the PR.
