Add a milestone 2 review and a brief to finish it

A review of milestone 2 at f84a29e against the plan's done-criteria and the milestone brief. This first version covers two of its nine areas: whether the doc's examples typecheck, and whether each error the spec describes has a test with its message. Every check passes under nix flake check, eval and fake ship, but the full module checker reports almost every spec error with a generic "needs unsupported inference" message, and the island, page and store checks reject small valid edits of the doc's examples, often blaming a correct line. docs/prompts/milestone-2-finish.md briefs what is left: the general checker core chosen in review question 5, kept diagnostics, a usefulness check for patterns, one types pipeline, every spec error, general kinds and APIs, the import table, tests and docs. The probes behind the findings, with the checker's output and a script to rerun them, are in docs/reviews/2026-11-03-milestone-2-probes/. Docs only; no check reads these files.

1+# Finishing milestone 2

3+A brief for the developer who finishes milestone 2 of Jibb, types and prelude. Paste it as the first message of a session, or hand it to a person; it assumes the repo `iko-soy/jibb`. Written 2026-11-03, at commit `f84a29e`, from the [milestone 2 review](../reviews/2026-11-03-milestone-2-review.md) of the same day. That review was still running in seven of its nine areas when this was written; where a section below depends on them it says so, and both files will be updated when they finish.

5+---

7+You are finishing milestone 2 of Jibb, a UI language for Urbit: a Hoon dialect with an indentation layout, whose compiler is a Hoon library, `jibb-dev/lib/jibb.hoon`. Milestone 1 built the layout pass and the parser. Milestone 2 has built a large partial type checker, a Hoon type importer and most of the prelude; every check passes, under `urbit eval` and on a fake ship, and the doc's 14 `jibb` blocks check as written. What is missing is a checker that is general rather than fitted to those examples, and that tells the user what is wrong.

9+## Read first

10+

11+1. [docs/reviews/2026-11-03-milestone-2-review.md](../reviews/2026-11-03-milestone-2-review.md): the verdict, findings M1 to M17, and the table of the 33 errors the spec describes. This brief is its to-do list.

12+2. [docs/prompts/milestone-2.md](milestone-2.md): the original brief. Its "What the doc asks of the checker", "Suggested design" and "Tests" sections still hold, and this brief doesn't repeat them.

13+3. [docs/spec/implementation-plan.md](../spec/implementation-plan.md), milestone 2, and the spec tabs it points at, closely Grammar's Tag resolution, Literals by context, Patterns, Modules and Imports.

14+4. [docs/reviews/2026-11-02-questions.md](../reviews/2026-11-02-questions.md): the owner's answers, marked *(chosen)*. Q5 and Q6 set the direction below. Q16 to Q28 are proposals waiting for @iko, not spec.

15+5. [docs/development.md](../development.md): setting up (`nix develop`), the tools, the test suites, and the checks before pushing (`tools/check` or `nix flake check`).

16+6. `git log origin/master`: @iko works in `jibb.hoon` in parallel, and another thread is implementing syntax-review proposals S1, S2, S4 to S7, S11 to S13 and S15 ([syntax review](../reviews/2026-11-02-syntax-review.md)). Rebase often and keep your changes out of theirs where you can.

17+

18+## Ground rules

19+

20+The original brief's rules hold: the spec wins, language questions go to @iko and are recorded in Decisions first, no built-ins, everything is a golden test that passes under eval and on the fake ship, push straight to `master` in commits that each leave every check passing, and keep `docs/` current. Two more:

21+

22+- **Fail closed, but say why.** A program the checker can't yet handle must be rejected, never accepted, and its message must name the construct and its site. "module definitions need unsupported inference: <path>: ++ x" is not an acceptable message for an error the spec describes.

23+- **Delete what the core replaces.** When the general core covers a recovery path or a "source-proven" slice, delete the slice and keep its tests. The milestone is done when the slices are gone, not when they are joined by a core.

24+

25+## What is left

26+

27+In order. Steps 1 and 2 can start at once; the rest build on step 2.

28+

29+### 1. Keep the diagnostics the checker already finds (M1, M12, M17)

30+

31+The full checker, `infer-jibb-file-detailed`, drops every per-definition reason in `add-supported-result` (`jibb.hoon` 10670-10689), so almost every error reaches the user as the generic message. The partial report already computes most of them. Thread a diagnostic, an `idiag` with its sites, through `add-supported-defs-core` for each unresolved definition, mold and kind check, and render the first in dependency order where the generic text is built today (14820-14857). Keep the generic text only for real checker limits, and make those name the construct. Make `module-scope-valid` return the shadowed name and both sites, with its own wording for `proj`. This plumbing carries over to the core of step 2.

32+

33+### 2. The general checker core (Q5)

34+

35+The owner chose this on 2026-11-02: union-find bindings with levels, a queue of deferred constraints, and a usefulness check for matches, built before more recovery paths. It is a long piece of work, so first write its design as a new section of the library's design notes, and share it in the project chat for @iko before replacing code.

36+

37+- **Unification**: union-find over type variables, with levels for generalization instead of environment scans; an occurs check; aura variables and the "is an atom" and "contains no gates" constraints carried on the variable, as `0858191` already does for gate-freedom.

38+- **Deferred constraints**: tags, `~`, numbers and cells, wing access, changes and `?-` on a type not yet known each wait in one queue, retried as variables are bound, as the Grammar's Tag resolution says. A tag-constrained variable does not generalize and stays open until something in the module fixes it. At the end of the module, each still-open constraint is an error at its source: "nothing fixes the union of %add; add a `^-`".

39+- **Order**: infer `++`s by the strongly connected components `839f6b0` already computes, a group of mutually recursive gates together; reject a non-gate value that depends on itself, naming the cycle.

40+- **Kinds by type**: check `main` as an ordinary expression. `(program init update view subs)`, `(page load view)` and `(store init update)` are calls whose unification fixes their components' types, messages included, so a tag in `view` is resolved by `main`. Then read the kind from `main`'s type, as the Grammar says, and run each kind's own checks after inference: gate-free island data and models, naming the field; for islands, a walk of the `(list (sub M))` that asks for a watchability proof only for `%watch`; for pages, a load that is any gate to `(ask D)`, `pure` and typed paths included.

41+- **Then delete** the program, page and store recovery chain, the deferred transactions, the prepared-tuple route and the other example-shaped slices as the core covers their tests (the earlier review counts about 1,180 lines of program recovery alone).

42+

43+When this is done, M2 to M5 are gone: every valid variant in the review's [probe corpus](../reviews/2026-11-03-milestone-2-probes/) checks, and each error in an island is reported where it is, as `button "Add" %submitt` giving "msg has no case `%submitt`" at the tag, with the union's site.

44+

45+### 3. Patterns by a usefulness check (M10)

46+

47+Replace the per-case coverage loops with Maranget's usefulness check over nouns: constants and cells, a loobean as its two constants, lists and units as their unions, nested patterns, literal patterns, `*` and bare names. It gives the missing-case error with a witness, at the `?-` and its subject, and the dead-arm error naming the arm that covers it, for the Grammar's `[%move * *]` example too. Keep the matrix reusable: milestone 3 lowers `?-` with it.

48+

49+### 4. One types pipeline (Q6, M14, M15)

50+

51+Render `types.txt` from the full checker: each definition's type, the module's kind, or the error with its excerpts. Retire the partial report, or make it a view of the full result. Give every `doc-*` case a `types.txt`, with the buttons error for `doc-grammar-02-buttons`.

52+

53+### 5. Every error the spec describes (done-criterion 2)

54+

55+Work down the review's [error table](../reviews/2026-11-03-milestone-2-review.md#appendix-the-errors-the-spec-describes) until every row says Met: a golden case with the spec's message, from the full checker, naming both conflicting sites with excerpts. The rows with no message anywhere today: a capital made `@ud` or a list, `~[text "hi"]` with its suggestion, `(facts …)` outside an API's `paths`, a gate in island data or a model with the field named, `[]`, a generic aura in `{…}` or a path's `(…)`, an imported vase or repeated record face, and a repeated attribute in a literal list, which today is accepted (M9).

56+

57+### 6. Kinds, APIs and the prelude in general (M4, M7, M9)

58+

59+- Pages: the overview's route-parameter page, `(post.api slug same)`, and its catch-all page, `(pure p)`, check.

60+- Islands: `|=(m ~)` for no subscriptions, several watches, `%every`, and a watch with a fold, `(changes.todo |=%got apply)`, check.

61+- Stores: a `poke` with several cases checks.

62+- APIs: an API other than the todo one checks as a module, with typed segments, several parameters, `scry=` paths and folds; `(facts …)` outside `paths` is an error.

63+- `element` can't be built by hand: `^- (element !!) [%island 5]` is rejected, so island data is always checked against `init`.

64+- The prelude: every name in the overview's Prelude and Layout tables is usable with its signature, or listed as deliberately left out. `max` is missing today, so the Grammar's `clamp` example fails. The inventory and its gaps are still being reviewed.

65+- The inline Grammar examples in M7 check: `|=(p title.p)`, `"{(add 1 2)}"`, path and unit literals, and every row of the Patterns table.

66+

67+### 7. The Hoon import table (done-criterion 3)

68+

69+A test `/sur` file with `$%`, `$@`, a map and a recursive mold, imported, printed in Jibb's notation and used from a Jibb module through the full checker, under eval and on the ship. Each row of the overview's import table works or gives the table's error where used. Known gaps from the earlier review: only `%tas` head tags (`%&`, `%|`, `%0` and `(each a b)` fail, A50) and no bare `@` or `@uw` (A14). The review's import area is still running and will add to this list.

70+

71+### 8. Tests (M6, M8, M16)

72+

73+- A ship check of the `my-app` desk as the original brief asks: build each `/sur` and mark through Clay, run the full checker over every `/ui/**.jibb` in dependency order, expect exactly one failure, `buttons.jibb` at 3:16, and record the time in `status.md`.

74+- Turn the spec-valid negatives (two `each` sites, a mapper alias, a page alias, an indirect or `pure` load, a store alias, a hand-built main) into positive cases. Fix `tests/type-page-main/hand-built-load.txt`, which doesn't parse. Make every negative assert its message and place, not only "rejected".

75+- Turn the review's [probe corpus](../reviews/2026-11-03-milestone-2-probes/) into a regression suite: its about 90 valid one-edit variants of the doc modules check, and its wrong variants and error probes fail with their own error at their own site.

76+- Guard the copies: the Core language block as a slice of `todo-list.jibb`, and `tests/type-buttons/valid.txt` as the buttons block without `add-button`.

77+

78+### 9. Speed

79+

80+The original brief asks that "a 2,000-line module should check in seconds, not minutes". Measure the full check of generated modules, written bottom-up and top-down, and of the `my-app` desk, with `tools/hoon --no-debug`, and record the numbers in `status.md`. The review's speed area is still running and will add its measurements here.

81+

82+### 10. Docs

83+

84+`status.md` becomes the capability table that Q41 asked for, then shows milestone 2 done with counts and timings. `compiler.md` and the library's header stop saying milestone 1, and describe the core. `open-questions.md` lists what is still open, and `decisions.md` records any new decision.

85+

86+## Out of scope

87+

88+As in the original brief: lowering and the backends (milestone 3), routes, static files, the theme's contrast check and the host (milestone 4), `load`'s per-request behaviour (milestone 5), the JavaScript runtime (milestone 6) and the formatter (milestone 7). Also the syntax-review changes another thread is making.

89+

90+## When you're done

91+

92+- The plan's three "Done when" items hold, but for the route check: the doc's examples and the review's valid variants check; every row of the error table is Met; the `/sur` import test passes.

93+- Every check passes, under eval and on the ship (`nix flake check`), and the `my-app` desk checks on the ship with its types read through Clay.

94+- The recovery paths and slices the core replaced are deleted.

95+- `docs/status.md` shows milestone 2 done, with counts and timings, and the other docs describe the checker as it is.

96+- Everything is pushed to `master`, and a few lines go to @iko in the project chat: what changed, the counts and timings, the decisions needed, and what is still open.

1+# Probes for the milestone 2 review

3+The Jibb sources the [milestone 2 review](../2026-11-03-milestone-2-review.md) ran through the full module checker, `infer-jibb-file-detailed`, at `f84a29e`, with what the checker printed then. They are evidence for the review and a ready regression corpus for [finishing milestone 2](../../prompts/milestone-2-finish.md). No check runs them: they are not tests, and several outputs record what is wrong today.

5+Each `.jibb` file holds sections, each starting with a line `#### <label>`; each section is checked as a module on its own. A `.out` file is the output of its `.jibb`: per section, `CHECKED` and the exported molds and values with their types, or `REJECTED:` and the message.

7+| Files | What they hold | Run with |

8+| --- | --- | --- |

9+| `variants/p1.jibb` to `p10.jibb` | The `my-app` modules and the doc blocks as written (`p1`), then about 90 spec-valid one-edit variants of them (`p2` to `p8`: reordered, renamed, extra helpers, a second watch, `\|=(m ~)` subscriptions, aliases, typed and `pure` loads) and wrong variants that must fail with their own error (`p9`, `p10`, labels starting `BAD-`). A label is the module's path, then a name | `run app` |

10+| `errors/p1.jibb` to `p5.jibb` | One or more probes for each error the spec describes, labelled as in the review's error table (`E01` an aura mismatch, `S2` the Grammar's `[%move * *]`, `C1` `%submitt` in an island, `W1` to `W4` island initializers) | `run plain` |

11+| `errors/import-check.hoon` | Invalid Hoon imports (`I1` to `I9`), module-graph errors (`M1` to `M5`) and the raw reader results | `run imports` |

12+

13+`variants/p1.jibb` has no saved output; every section in it checks, except `buttons`, which fails with "nothing fixes the union of %add".

A label of the form `<path> module <name>` adds that section to the bundle instead. Each run takes 30 to 80 s, most of it building the libraries.

1+# Milestone 2 review, 2026-11-03

3+A review of milestone 2, "Types and prelude", at [`f84a29e`](https://github.com/iko-soy/jibb/commit/f84a29e1a0af663afdb77e793c933470b59a249b), asked for in the project chat. It judges the combined result of the milestone's commits, from `1dd92a6` ("Start type inference and Hoon imports", 2026-10-30) to `f84a29e`, about 150 of them, against the plan in [implementation-plan.md](../spec/implementation-plan.md) and the brief in [prompts/milestone-2.md](../prompts/milestone-2.md). It builds on the [repository review of 2026-11-02](2026-11-02-repo-review.md) (findings A1 to A137, at `4bf477e`) and does not repeat what that review settled.

5+**This is a first version.** The review runs in nine areas. Two have finished: whether the doc's examples typecheck (done-criterion 1) and whether every error the spec describes has a test with its message (done-criterion 2). The other seven are still running: the Hoon import table (done-criterion 3), inference soundness, unions and `?-`, modules, APIs and the prelude, what became of the earlier review's findings, tests and docs, and architecture and speed. Their results, and a second reviewer's check of every finding, will be added to this file. The findings below had one reviewer each, who reproduced them with probes; the headline ones (M1, M2, M3 and M9) were reproduced again for this write-up.

7+What is left to build is briefed in [prompts/milestone-2-finish.md](../prompts/milestone-2-finish.md). The probe sources behind the findings, with the checker's output for each, are in [2026-11-03-milestone-2-probes/](2026-11-03-milestone-2-probes/), with a script to rerun them.

9+Line numbers are links into `f84a29e`.

10+

11+## Verdict

12+

13+**Milestone 2 is not done by its own "Done when" list.** Every check passes, the 14 `jibb` blocks of the doc check as written, and nothing wrong that the core probes tried was accepted. But the checker that a build will run, the full module checker, reports almost every error in the spec as "module definitions need unsupported inference: <path>: ++ name", with no line, column or excerpt. And the island, page and store checks are fitted to the examples' exact shapes, so small valid edits are rejected, often with a wrong error. `docs/status.md` still says "In progress", which matches; its rewrite as a capability table (`e97aebe`) landed while this review ran.

14+

15+| Plan item | Status | Evidence |

16+| --- | --- | --- |

17+| Done when: the doc's examples typecheck, except those written as errors | **Met as written, fragile** | All 14 blocks check with exact types (`jibb-doc-examples`, `jibb-todo-full`, `jibb-store`, `jibb-page-main`, `jibb-theme`, `jibb-buttons`), and `add-button` fails with "nothing fixes the union of %add". Of about 90 spec-valid one-edit variants of those modules, about 27 are rejected (M2, M4) |

18+| Done when: each error the Grammar tab describes has a test with its message | **Not met** | Of the 33 errors the spec describes, 4 have a test and get their message from the full checker. 28 don't get their message from the full checker, most of them only the generic "needs unsupported inference"; the partial report, which no build runs, has a message for most of those. One, a repeated attribute, is accepted (M1, M3, the [error table](#appendix-the-errors-the-spec-describes)) |

19+| Done when: a `/sur` file with `$%`, `$@`, maps and a recursive mold imports as the table says | Not yet reviewed | Still running. The earlier review's A50 (only `%tas` head tags, no `each` or `json`) and A14 (bare `@`, `@uw`) were open at `4bf477e` |

20+| Each milestone ends with its checks passing on a fake ship | **Met** | `nix flake check`: 11 of 11 checks pass, the ship group on a fresh fake `~zod` ([Check run](#check-run)) |

21+| Brief: on the ship, the `my-app` desk checked with its Hoon types read through Clay, every module but `buttons.jibb` checking | **Not met** | No check walks `my-app/ui`. The suites compile `/sur` and mark text themselves with `ride`; Clay-built types reach only the partial report (M8) |

22+| Builds: exhaustive `?-` with dead-arm errors | Partly | Flat whole-case unions only; the Grammar's own `[%move * *]` example is "not supported" (M10) |

23+| Builds: the prelude's types | Partly | `max`, which the Grammar's `clamp` example calls, is missing; a repeated attribute is accepted; a hand-built element checks (M9). The full inventory review is still running |

24+| Builds: Hindley–Milner inference, deferred constraints, union disjointness, imports, API files | Still running | Early probe results are under [Early results](#early-results-from-the-areas-still-running) |

25+

26+## Check run

27+

28+`nix flake check` at `f84a29e`, on 4 CPUs, took 471 s and passed every check:

29+

31+| --- | --- | --- | --- |

34+

35+The corpus has 691 golden cases, 304 of them with a `types.txt`, and 58 suites in `tests/lib` with 62 test arms. All 304 `types.txt` files are partial reports that begin "partial inference; module not checked".

36+

37+## What works

38+

39+- The 14 doc blocks check with exact, closed types, including the todo island, the cart store and basket, the theme, the three pages and the imports example, and the `cmd`/`sub` block as prelude source.

40+- About 64 of 90 valid edits to those modules still check: reordering and renaming, unused helpers, consistent field swaps, an `init` written as a cast, a sixth message, helpers in `view`, two islands on a page.

41+- Overlapping union cases, a repeated field in a Jibb record, and derived-name clashes get good errors from the full checker, with both sites and excerpts. The unresolved-tag error of the Grammar's buttons example is exact, and moves with the code when the block is reordered.

42+- None of the wrong programs probed in this version was accepted, apart from the two in M9.

43+

44+## Findings so far

45+

46+Severity follows the earlier review's scale: high means unsound, or a done-criterion clearly not met, or a false error on common valid code.

47+

48+| # | Finding | Severity | Evidence | Fix | Prior |

49+| --- | --- | --- | --- | --- | --- |

50+| M1 | **The full checker throws away every per-definition diagnostic.** An aura mismatch, mismatched faces, `msg has no case %submitt`, a missing `?-` case, a covered arm, `++ title (trim title)`, a shadowed local, a cell in `{…}`, a capital made `@ud`, `m()`, `[]`, `(add %.y %.n)`, a gate in `eq`, an unknown name and every invalid Hoon import all give only "module definitions need unsupported inference: /ui/probe/jibb: ++ x". The partial report has a definite message with sites for most of them | High | [`add-supported-result`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L10670-L10689) returns `~` on a failed result and on hole, capital, pending-tag and atom-variable failures, dropping the reason. Only the pending-tag and sample-shadow retries rebuild an error ([14820-14832](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L14820-L14832)); mold and kind failures go the same way ([14856-14857](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L14856-L14857)) | Keep the first definite diagnostic per unresolved definition and render it at 14830, in dependency order; keep the generic text for real checker limits. Same for molds and kinds | A40, A12 still open |

51+| M2 | **Valid one-edit variants of the doc's islands are rejected, mostly with a false error at a correct line.** `++ subs \|=(m ~)`, which the overview gives for "no subscriptions", a second watch, an inline or local mapper, two `each` sites, and an update helper that returns a poke command each give "todo-list.jibb:14:28: nothing fixes the union of ~", pointing at `error=~` in a correct `init`. Any `%every` subscription, and a watch with a fold (`(changes.todo \|=%got apply)`, from the overview), give "module kind needs unsupported inference" | High | `main` is not checked as an application: a fixed chain of program recoveries fits each component, and a definition the chain can't resolve falls to the pending-tag retry, which reports whatever tag is still open ([10711-10735](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L10711-L10735)). The Grammar says such a constraint "stays open until something in the module fixes it. An island's `main` fixes its messages" | The general core of Q5: check `main = (program init update view subs)` as an ordinary application whose unification fixes the components, with module-wide deferred tag constraints. Walk the `(list (sub M))` and ask for a watchability proof only for `%watch` | A121, fix-first 1 in a new form |

52+| M3 | **In an island, every error is reported as "nothing fixes the union of ~" at `init`.** The criterion's own example, `button "Add" %submitt` in the todo view, gives "todo-list.jibb:14:28: nothing fixes the union of ~". So do `\|=%typd`, a pattern typo, a missing `[%acked err]` arm, a second `%submit` arm, an aura mismatch in `update`, and a gate as a row key. Outside an island, the partial report puts the caret under `"Add"`, the wrong argument | High | Probes of the unchanged island with one edit each, reproduced for this write-up. The same in the basket: "basket.jibb:15:16: nothing fixes the union of ~". A gate in the model gives "module kind needs unsupported inference" and names no field, though the overview says "the checker names the field" | Report a pending tag only when the definition otherwise checks in its module context. For a call whose sample fit fails, re-fit each argument and report the first failing one, as "msg has no case `%submitt`" when it is a tag | A121 |

53+| M4 | **Page and store kinds are recognised by syntax**, so the overview's route-parameter page (`(post.api slug same)`), its catch-all page (`(pure p)`), a typed-path load, `(pure ~)`, a page or store alias, and the cart's `init` without its cast are rejected | Medium | [`page-main-parts`, `store-main-parts`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L13200-L13240) match the literal `(page w w)` and `(store w w)`; [`page-load-derived`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L14510-L14538) takes only a gate whose body is one derived request. The Grammar says "`main`'s type decides a module's kind" | Decide the kind from `main`'s inferred type. Check a load as a gate to `(ask D)`, `pure` and typed paths included; pages need no watchability | A121 |

54+| M5 | **An island `init` mismatch is blamed on a correct `~`.** In `[ts ~zod ~]` against `draft=@t`, the error is `~zod`, but the checker says "nothing fixes the union of ~" at the last `~`. `jibb-program-init` locks three such messages | Medium | `tests/type-program-main/initializer-earlier.txt` and two siblings; [`jibb-program-init.hoon:129-131`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/tests/lib/jibb-program-init.hoon#L129-L131) | As M3, then update the three expected strings | |

55+| M6 | **Negative tests lock in rejections of valid programs, one fixture doesn't parse, and negatives check only "rejected".** Two `each` sites and a mapper alias (`jibb-todo-full`), a page alias, an indirect and a `pure` load (`jibb-page-main`), an alias and a hand-built main (`jibb-store`) are all spec-valid. `tests/type-page-main/hand-built-load.txt` fails to parse, so its case passes on a parse error. Every `jibb-todo-full` negative, "wrong message" included, fails with the same `~` error and the arm compares only "<label>: rejected" | Medium | [`jibb-todo-full.hoon:121-168`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/tests/lib/jibb-todo-full.hoon#L121-L168), [`jibb-page-main.hoon:164-167`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/tests/lib/jibb-page-main.hoon#L164-L167), [`jibb-store.hoon:261-262`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/tests/lib/jibb-store.hoon#L261-L262). The fixtures also still use the positional `[ts "" ~]` that `44e3324` replaced in the doc | Move the valid cases to positive expectations, marked as known gaps until they pass. Fix the fixture. Make each negative assert its message and place | |

56+| M7 | **Inline Grammar examples meant to check are rejected**: `(turn ps \|=(p title.p))`, `"{(add 1 2)}"`, `/posts/~zod` (even under `^- path`), `` `5 `` without a cast, the Patterns rows `1.000`, `~zod`, `"milk"`, `[x ~]`, `[[~ a] [~ b]]` and `[~ b]`, `(eq xs ~)`, `(clap `1 `2 add)`. `clamp` fails because the prelude has no `max`, and the unknown name is reported as "unsupported", not as unknown | Medium | Probes, one module each. `inline-pattern-literals` and `inline-pattern-nested` have no `types.txt`, so nothing tests them | Add a typed case for each, and support them in the general core | |

57+| M8 | **No check runs the `my-app` desk with its Hoon types read through Clay**, as the brief asks, or asserts that every module but `buttons.jibb` checks. `card.jibb` and `api/blog.jibb` are checked only as imports, with no asserted type. No `my-app` timing is recorded | Medium | The suites read `/sur` and mark text with `/*` and `ride` it after dropping `/-` lines ([`jibb-todo-full.hoon:29-53`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/tests/lib/jibb-todo-full.hoon#L29-L53)). `tools/clay-fixtures` builds types with `.^(vase %ca …)` but feeds only the partial report | A ship check that builds each `/sur` and mark through Clay, runs the full checker over every `/ui/**.jibb` in dependency order and expects exactly one failure, `buttons.jibb` at 3:16, timed | |

58+| M9 | **Two wrong programs are accepted.** A repeated attribute, `(column ~[gap+%s1 gap+%s2] ~[(text "x")])`, checks as `(element A)`, though the overview makes it an error. A hand-built element, `^- (element !!) [%island 5]`, checks as `(element !!)`, bypassing the island's check of its data against `init` | Medium | Both reproduced with the full checker. [status.md](../status.md) lists raw-constructor encapsulation and duplicate-attribute checks as missing; nothing tests either error | Report a repeated head tag in a literal `(list attr)` with both sites. Make `element`'s constructors the only way to build one, or check its payloads | |

59+| M10 | **`?-` exhaustiveness and dead arms cover only flat whole-case unions.** A missing case has no site ("missing union case %c"); a covered arm doesn't name the arm that covers it; the Grammar's `[%move * *]` then `[%move %left n]` is "union pattern is not supported"; a loobean without `%.n` and a list without `[i t]` are "branch pattern is not supported"; a repeated `%.y` says "branch does not cover both loobeans" | Medium | Partial report; the full checker is generic for all (M1). The loop matches arms to whole cases ([8225-8311](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L8225-L8311)) | The usefulness check Q5 chose (Maranget): a missing-case witness at the `?-`, and a dead-arm error naming the covering arm, for loobeans, lists, units and nested cells | A15 still open |

60+| M11 | **Errors in imported Hoon types are generic in the full checker**, and a vase, a record with a repeated face, and most overlapping `$%`, `$?` and `$^` have no definite message in either pipeline | Medium | The reader is definite for signed and float auras and for cores and gates, and the partial report shows them at a use site. A vase is only `%unsupported` ([`jibb-import.hoon:1560`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb-import.hoon#L1560)); `[a=@ud a=@t]` reads as ok and the bridge drops it silently | Reuse the partial path's import diagnostics through M1. Give vases and repeated faces `%invalid` codes. Extend the overlap witness | A56 |

61+| M12 | **Shadowing and `proj` errors name neither the name nor its sites.** `++ add 1`, `+$ list @ud`, `++ proj 1` and a definition named like an import face all give "module has conflicting names: /ui/probe/jibb". A shadowing local or pattern binder is generic in the full checker | Medium | [`module-scope-valid`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L11760-L11773) returns a bare `?`. Only a gate sample gets a definite error | Return a diagnostic naming the binding and what it shadows, with a separate wording for `proj` | A43 partly |

62+| M13 | **Several errors the spec describes have no definite message anywhere**: a capital that a body makes `@ud` or a list, `~[text "hi"]` with its suggestion, `(facts …)` outside an API's `paths`, a gate in island data or a model naming the field, `[]`, and a generic aura in `{…}` or a path's `(…)` | Medium | Each probed in both pipelines: "explicit capital constraints are not supported", "list item constraint is not supported", "module mold needs unsupported inference", "module kind needs unsupported inference". No code suggests `~[(text "hi")]` | One definite diagnostic each, with a golden case | A6, A100 for `[]` |

63+| M14 | **Message tests lock the partial report, which no build produces.** For about 20 of the 33 errors, the only test asserts a message the real checker never gives | Medium | `tools/golden` calls only the `golden-types-*` entry points ([`tools/golden:248-262`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/tools/golden#L248-L262)). The program suites lock the generic strings themselves, as at [`jibb-program-watch.hoon:178`](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/tests/lib/jibb-program-watch.hoon#L178) | Q6: render `types.txt` from the full checker, and add one case per error in the catalogue, with the doc's own examples | A122 still open |

64+| M15 | **The goldens never show a doc example checking.** 11 of the 14 `doc-*` cases have no `types.txt`; the other 3 are partial reports, and `doc-grammar-04-step` says "+$ step: cases proven disjoint; mold not checked" although the full checker accepts it | Low | `grep -L '^partial inference' tests/golden/*/types.txt` finds none | As M14 | A122 |

65+| M16 | **Two fragment checks rest on unguarded copies.** The Core language block is "checked inside the todo island" only because `todo-list.jibb` lines 16-25 equal `tests/golden/doc-core-02-update/source.jibb`, which nothing compares. `tests/type-buttons/valid.txt` is a hand copy of the buttons block | Low | `sed -n 16,25p my-app/ui/todo-list.jibb \| diff - tests/golden/doc-core-02-update/source.jibb` is empty today; no tool references `doc-core-02` | Assert the slice in `tools/doc-blocks` or `jibb-todo-full`; derive `valid.txt` from the doc block | |

66+| M17 | **Message polish**: an import cycle names one path, with no `/=` line or chain; "nothing fixes the union of %add" doesn't ask for a `^-` as the Grammar says; an overlap doesn't suggest an open `[`; some mismatch sites print no types; an imported union is named by its cases | Low | [12303-12304](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L12303-L12304), [5363](https://github.com/iko-soy/jibb/blob/f84a29e1a0af663afdb77e793c933470b59a249b/jibb-dev/lib/jibb.hoon#L5363) | Report the cycle as a chain; append "; add a `^-`"; add the hint; print types at every site | A136 |

68+## Early results from the areas still running

69+

70+These come from probes the inference reviewer had run when this version was written. They have not been through that reviewer's own write-up or a second reviewer, so treat them as leads:

71+

72+- Every wrong program in about 40 soundness probes was rejected, except the two in M9 and a gate passed where `*` is expected (A23, known).

73+- Common valid code is rejected as "unsupported": a sum with `roll`, a pair of mutually recursive top-level gates, list reverse, factorial, a recursive count, a pattern binding the rest of a list, wing access on a union or list, and patterns over atoms with number or string literals.

74+- `~[1 "a"]` checks as `(list @t)`: a bare decimal takes the aura `@t`. The spec allows that today; syntax-review proposal S4 would forbid it.

75+

76+## Appendix: the errors the spec describes

77+

78+From [grammar.md](../spec/grammar.md), [overview.md](../spec/overview.md), [core-language.md](../spec/core-language.md) and [decisions.md](../spec/decisions.md), leaving out milestone 1's parse errors and the route, static-file and contrast checks that the brief leaves to milestone 4. "Full" is what `infer-jibb-file-detailed`, the checker a build runs, reports; "generic" is "module definitions need unsupported inference: <path>: ++ name". "Partial" is the report `types.txt` shows.
