+The task board's Done column is one archive page of 20 cards, and until now it presented that page as the whole story: a Bot with 45 finished tasks read **Done 20**, and its rail row read **20/22** as if 22 were everything. When the archive page is full the column heading now reads **20 newest** and the rail row reads **20+ done** — what was drawn, and that there is more; a page under the limit, and the empty board, read exactly as before ([#2045](https://github.com/ThinkFlowLab/FlyBot/issues/2045)).

It is used where a row is built (`previewOf` in `src/client/text.js`, the group row in `src/client/sidebar.js`, the host's `preview` in `src/host/channel.js`), so no surface has to remember it, and by the details drawer's copy export: `transcriptOf` (`src/client/text.js`) reads each stored turn through the same helper, so a copied conversation carries the words, not an untrusted fence, and `copyBodyOf` drops a leading delegation trace only when its first hop is a Bot's name taken from the roster (`copyNames`; longest first, and no names strips nothing), which keeps a line like `Settings → Models 页面` as written; a copied reply keeps its own line breaks, and only a trace-only line or a fence-marker line is dropped.

That read without `limit` stays uncapped on purpose: it is the id-lookup and tooling path (`statusOf`, a Bot reading a settled row), not what the board polls.

Drag or **Start** / **Complete** calls `actions.taskUpdate`; only the Bot's owner gets those actions. A group scope loads `tasks { roomId }`. Since #1252 the default read is active work only and the Done column merges a second read of the finished rows — `tasks { ...query, archive: true, limit: ARCHIVE_SHOWN }`, which is room-scoped for a group and names the Bot for a Bot board, because the host cuts the page before the board can filter by Bot — newest-settled first by `updatedAt` (tiebreak `createdAt`), finished rows only, and cut to that limit, so a room with hundreds of finished cards still renders a twenty-card column while the poll carries the slice and not the history. Since #2045 that page is also counted for what it is: when the archive holds a full page (`ARCHIVE_SHOWN`), the Done heading reads `20 newest` and a Bot's rail row reads `20+ done` rather than a fraction that would present the page as the history; a page under the limit keeps `{done}/{total}` exactly as before. That read without `limit` stays uncapped on purpose: it is the id-lookup and tooling path (`statusOf`, a Bot reading a settled row), not what the board polls. Finishing a card moves it off the active list at once, before the next poll. Tests: `core/test/kanban.test.js`. |
 | `core/src/client/standing-approvals.js` | Standing tool approvals (#540): `StandingApprovalsCard`, the **Always allowed** card in Bot settings (the Bot's grants) and Group settings (the grants this person gave in the group), one row per kind with **Remove** (`actions.removeStandingApproval`). The approval cards (`member-status.js` `ApprovalCard`, the inbox card) add **Always allow for this Bot** and, for an ask from a group, **Always allow for this group** (`alwaysChoices`; never on a friend's Bot). Host side in [core-host](core-host.md#standing-tool-approvals-540). Tests: `core/test/member-status.test.js`, `core/test/standing-approvals.test.js`. |
