| 1 | // verify_daimonreach.mjs — a daimon reaches what its Diamond holds. |
| 2 | // |
| 3 | // THE DEFECT THIS PINS, and it is the one a user hit on 2026-08-13. A 281-page |
| 4 | // Typst book was attached to a Diamond. The user asked its daimon to set up an |
| 5 | // editing loop over it. The daimon globbed `**/*chap*`, `**/*.typ` and `books/**`, |
| 6 | // found nothing, and reported that the book did not exist — then offered to CREATE |
| 7 | // the manuscript. All of that was correct behaviour from where it was standing: |
| 8 | // `src/wasm/app.rs` gave the steering turn `path_prefix: diamonds/<id>` and |
| 9 | // `root: FileRoot::Opfs`, so `.` was the Diamond's own scaffold in browser storage |
| 10 | // and the user's disk was not the filesystem it was looking at. The attachment had |
| 11 | // always reached the WORKERS (`scopeAgentTo`, www/js/daimond.js) and never the |
| 12 | // daimon that commands them. |
| 13 | // |
| 14 | // So, four properties, and the fourth is the one that turns a wrong answer into a |
| 15 | // destroyed afternoon: |
| 16 | // |
| 17 | // 1. A DAIMON READS WHAT ITS DIAMOND HOLDS, by the path the user would name. |
| 18 | // Not `diamonds/<id>/books/...`, which is where a prefix put it — `books/...`. |
| 19 | // 2. A DAIMON WRITES WHERE THE USER MARKED, and nowhere else. Reading is free |
| 20 | // across the workspace (2026-08-13, `diamond_bounds`); writing is the mark. |
| 21 | // 3. ITS OWN CRYSTAL IS STILL ITS OWN. The Diamond's directory lives in OPFS |
| 22 | // whatever folder is open, and `FileRoot::Workspace` must not follow the real |
| 23 | // folder for a store path or a daimon loses its memory to gain a book. |
| 24 | // 4. THE DAIMON IS TOLD WHAT IT HOLDS. A model that has to discover an |
| 25 | // attachment can conclude it is absent; one that is told cannot. This is the |
| 26 | // check that would have caught the whole incident in one line. |
| 27 | // |
| 28 | // EACH CHECK IS PROVED AGAINST BROKEN CODE FIRST. |
| 29 | // |
| 30 | // node dev/verify_daimonreach.mjs --break nomarks # 2 and 4 fail: the page reports no marks |
| 31 | // node dev/verify_daimonreach.mjs --break allmarks # 2 fails: every path is a mark |
| 32 | // node dev/verify_daimonreach.mjs # and then, clean |
| 33 | // |
| 34 | // The breaks go on WHAT THE PAGE ASKS FOR and never on the engine, for the reason |
| 35 | // `dev/verify_chatscope.mjs` gives: the engine is the thing under test, and a break |
| 36 | // that damaged it would prove only that a damaged engine misbehaves. |
| 37 | // |
| 38 | // THE WEB GRANT OF 2026-08-24 ADDED TWO MORE PROPERTIES, and their reds are named |
| 39 | // here rather than left to be re-derived. |
| 40 | // |
| 41 | // 5. A DAIMON HOLDS EVERY TOOL IN `Tool::web()`. Its red is `Tool::daimon()` with |
| 42 | // `t.extend(Tool::web())` taken out, which is the world before the grant: the nine |
| 43 | // offered-checks go red together and the belt falls from 28 tools to 19. |
| 44 | // 6. AND THE TAINT RULE STILL BITES ON THEM. Its red is the `Tool::WebFetch` arm of |
| 45 | // `Tool::execute` with its `egress_check` deleted -- a tool granted without its |
| 46 | // guard, which is exactly the world in which the grant would have been unsafe. |
| 47 | // Both taint checks go red, and the tainted fetch is seen going out to the gateway. |
| 48 | // |
| 49 | // THE TAINT NARROWING OF 2026-08-24 ADDED A SEVENTH, and it is READ OUT OF THE RUST rather |
| 50 | // than driven through the browser, so it answers even when the heavier half of this file |
| 51 | // cannot. Its breaks are in `src/tools.rs` and therefore not in `BREAKS`, which patches |
| 52 | // `www/`; they need no rebuild either, because these four checks read the SOURCE. |
| 53 | // |
| 54 | // 7. A COMMAND NARROWS THE TAINT AND KEEPS THE ENVELOPE. `Self::run` used to end |
| 55 | // `ctx.wrap_untrusted(...)` unconditionally, which put command output in an untrusted |
| 56 | // envelope AND took the network from every later command in the turn. Only the first |
| 57 | // was ever argued for. Four reds, each seen: |
| 58 | // |
| 59 | // `let body = ctx.wrap_untrusted(&origin, &s);` the world before — check 2 red |
| 60 | // `let body = s.clone();` envelope dropped — checks 1, 2 red |
| 61 | // `let body = wrap_untrusted(&origin, &s);` taint gone — check 2 red |
| 62 | // delete `fn fence_reaches_untrusted` checks 3, 4 red |
| 63 | // |
| 64 | // The second is the one to keep in mind: buying the network back by dropping the |
| 65 | // envelope is a bigger defect than the one being fixed, and it is silent. |
| 66 | // |
| 67 | // AND ONE BREAK THAT CHANGED NOTHING, WHICH IS WORTH MORE THAN A GREEN. `compose_daimon` |
| 68 | // shares the app's `read_seen` deliberately, so the obvious break was to give it a fresh |
| 69 | // `new_read_cache()`. It changed NOTHING: 29 of 29 still passed. Both calls in check 6 sit |
| 70 | // in ONE turn through ONE context, so what that sharing carries is taint from a turn BEFORE |
| 71 | // this one, which nothing here asks about. Said out loud so the next reader does not take |
| 72 | // check 6 as evidence about the sharing; it is evidence about the gate. |
| 73 | // |
| 74 | // ONE PROPERTY HAS NO BREAK HERE, AND IT IS PROPERTY 1 — say so rather than let a |
| 75 | // green imply otherwise. What broke it was the PIN, two fields in a Rust struct |
| 76 | // that no page can set, so there is no caller mistake to simulate. Its red proof is |
| 77 | // the previous build, which has the pin: check out the commit before this change, |
| 78 | // build the wasm, and run this file. That is written in the report rather than left |
| 79 | // as an exercise, because a check whose red has never been seen is not evidence. |
