59−The inference fragment supports fixed auras, unrestricted `@`, one-way widening into it and toward aura-family ancestors, generic variables and gates, unfaced cells, a two-binder cell pattern, a complete two-arm loobean branch, closed local mold aliases and acyclic forward value references. It instantiates generalized top-level definitions when they are used. Acyclic local value definitions can refer forward and generalize variables that are free of their enclosing environment; captured variables and explicit capitals remain shared. Acyclic simple local mold aliases can also refer forward, and are scoped to the body, not its gate's sample. Recursive local groups, and recursive, generic, union or faced local molds remain unsupported. It can infer and generalize atom constraints arising from explicit capitals or bare sample binders, preserve those constraints through aliases, instantiate them independently, and print multiple constraints. Unresolved decimal variables default to `@ud` for inferred types without gates; defaulting inside gate types and other constraint cases remain incomplete. It does not yet check a module, its imports, faces, general patterns, deferred constraints, recursive or generic molds, dependency cycles or most errors with both conflicting excerpts. Definite cast and call mismatches, incompatible branches and overlapping union cases report both sites and excerpts. Concrete branch results can join at an explicitly present parent aura or `@`; function compatibility involving nested `@` and variable-dependent joins remain unsupported except for equal types. The current dependency pass can take quadratic time on long forward chains; the milestone's speed target remains unverified. A separate conservative pass reports unions whose cases are provably disjoint or overlapping and leaves other cases unresolved; it does not claim the mold is checked. Unsupported forms are reported as such, and the partial output says the module has not been checked.

59+The inference fragment supports fixed auras, unrestricted `@`, one-way widening into it and toward aura-family ancestors, generic variables and gates, faced and unfaced cells, cell sample binders, known record field reads, a cell pattern of two or more binders, a complete two-arm loobean branch, a complete two-arm unit-shaped branch, closed local mold aliases and acyclic forward value references. For a supported single syntactic top-level recursive gate, the checker infers the sample first and uses that exact sample, including its field faces, in a monomorphic self placeholder. The completed body must unify with the placeholder before the gate is generalized; incompatible recursive arguments can report the call and argument sites. Uses of generalized top-level definitions instantiate their schemes independently. For a complete loobean branch with one direct self-call arm, the checker can infer the other arm independently and use its closed, fully resolved type to seed the recursive result; it then checks the whole body. Open or pending base types do not seed the result, and other branch shapes still depend on the existing partial inference. A supported single local recursive gate also uses a monomorphic self reference while its body is checked, then generalizes variables free of its enclosing environment; captured variables remain shared. Acyclic local value definitions can refer forward. The checker collects written capitals per `++` before inference, excluding nested definitions: a capital used in an enclosing definition is shared with its locals, even when written later, while a capital introduced only in a local definition is generalized there. Sibling locals can introduce independent capitals with the same spelling; generic mold parameters keep their own scope. Top-level groups of syntactic gates are inferred together with monomorphic placeholders and shared substitutions, then generalized only after the whole group checks; downstream uses and library interfaces instantiate those schemes independently. A dependency graph identifies groups with two iterative depth-first passes; its conservative local-reference edges can reject otherwise valid programs. Supported local mutually recursive gate groups also use shared monomorphic placeholders and generalize only after the group checks, preserving captured outer variables. Mixed gate/value cycles, polymorphic recursion, unresolved literal constraints and unresolved branch joins remain unsupported. Acyclic simple local mold aliases can also refer forward, and are scoped to the body, not its gate's sample. Nonrecursive generic aliases of supported molds can be applied at exact arity, including locally and through library interfaces; their parameters are lexical. Closed, provably disjoint nonrecursive unions and tagged single-case molds support contextual term values, `~` and `|=%tag` constructors. A null-headed cell can match a union case but does not supply a `|=%$` constructor; unresolved tags and nulls remain pending, with distinct partial-inference diagnostics. Nonrecursive top-level generic union molds with provably disjoint cases also support contextual tags and constructors at exact arity; their arguments are retained through generalization and supported library interfaces. Nonrecursive generic aliases can reorder, repeat or omit parameters while preserving a supported union’s origin, including through local scopes and library interfaces. A generic union declared directly inside a body remains unsupported, as do mutually recursive local groups and recursive molds. A value with type variable `A` can fit a field whose type is that same `A`, including in generic union payloads and nested or repeated record fields. A differing-variable face constraint remains unsupported. When inference forces two distinct explicitly written capitals equal, it reports both source sites; forcing a capital to a concrete type remains unsupported in this fragment. It can infer and generalize atom constraints arising from explicit capitals or bare sample binders, preserve those constraints through aliases, instantiate them independently, and print multiple constraints. Unresolved decimal variables default to `@ud` for inferred types without gates; defaulting inside gate types and other constraint cases remain incomplete. It does not yet check a module, complete imports, general patterns, general deferred constraints, recursive molds, dependency cycles or most errors with both conflicting excerpts. Definite cast and call mismatches, incompatible branches and overlapping union cases report both sites and excerpts. Concrete branch results can join at an explicitly present parent aura or `@`. Some known tuple and record positions acquire matching faces; other variable-dependent face merges, general branch tag context and ambiguous call-result propagation remain unsupported; function compatibility involving nested `@` and variable-dependent joins remain unsupported except for equal types. For a single recursive gate outside a group, the reporting path repeats inference rather than instantiating its generalized interface inside its own body; a group report uses its stored schemes. This adds work, and the current dependency pass can take quadratic time on long forward chains; the milestone's speed target remains unverified. A separate conservative pass reports unions whose cases are provably disjoint or overlapping and leaves other cases unresolved; it does not claim the mold is checked. Unsupported forms are reported as such, and the partial output says the module has not been checked.

61−The separate `jibb-dev/lib/jibb-import.hoon` is an unfinished reader for selected Hoon type graphs. It handles named recursion, nested map, set, queue, list, unit, jar and jug arguments, direct ordered maps, and direct `$^` unions whose source branches can be proved disjoint. It also reads ordered map fields in records when the map arguments are syntactically fixed atom molds and other fields are fixed atom molds or standard collections of static atom molds. Collection names must not be shadowed. The reader can also import a mark door sample, removing its outer sample face and validating its build subject. Nested `$^`, including `$^` in collection arguments, is rejected until its source branches can be checked; other nested ordered maps, general source-level disjointness and complete integration with the checker remain unfinished. `+golden-types-imports` can consume fixed-aura atoms and unfaced cells from caller-supplied reader results for declared `/-` imports; `+golden-types-with-marks` accepts those same shapes from declared mark imports in a separate list. Other forms remain unsupported. Its disjointness proof is conservative and can reject a valid union it cannot prove disjoint. Collection recognition requires the originating `/sur` core. The reader validates direct zuse subjects and Ford subjects consisting of faced imported cores and a validated tail, checking imported cores transitively; it rejects shadowed names, inconsistent core subjects and other subject shapes. For a recursive reference, the reader matches the exact Hoon hold against named arms in validated cores, including transitive Ford imports; it rejects missing, unlabelled or ambiguous origins. Its fixtures include three real Tlon files; `tools/importer-test` compares the internal projection under eval, and the ship test compares the same golden output. `tools/type-import-test` and `tools/type-mark-test` compare bridge reports under eval and on the ship. `tools/clay-fixtures` also passes Clay-built `/sur` molds and mark samples through the Clay-built importer and partial checker.

61+A single-arm cell pattern can bind two or more positions, with its last binder capturing the remaining tail. Duplicate and shadowed names are rejected. A definite non-cell spine fails; an intermediate union or collection that might contain a cell remains unsupported. Nested patterns, wildcard patterns and faced records are not covered by this rule.

6262

63−Callers that have a `/sur` core and a name can use `+read-named`: it checks for a locally declared arm before asking Hoon to evaluate the mold, and reports evaluation failures with the final Hoon trace line. `+read-mold-in` remains available when the caller already has the selected type. The checker currently treats a failed import as unsupported rather than rendering the importer's error.

63+String interpolation infers its pieces in order and preserves substitutions and pending constraints. A piece with a known atom aura, unrestricted `@`, or a tape `(list @tD)` is accepted; an isolated decimal literal takes its normal `@ud` default. A known cell reports that it needs a printer, and an explicitly generic atom asks for an aura at its use site. Loobeans, term singletons, non-tape collections, open types and a type fixed only later remain unsupported in this fragment.

6464

65−`+golden-types-with-prelude` accepts case-local Jibb module sources alongside `/sur` and mark results and the vendored prelude source. It resolves reachable ordinary library modules in dependency order, exporting supported closed value schemes and simple mold aliases. It reserves names from the supplied prelude, detects missing sources and cycles, and rejects a dependency if its interface cannot be inferred by the fragment. API files, modules with `main`, unsupported definitions and many other features remain outside this subset; the prelude inventory itself is incomplete. The older `+golden-types-with-modules` entry point fails closed for imports because it has no prelude scope. Neither entry point claims the module has been checked.

65+The Hoon bridge translates imported `*` as the any-noun type, directly or within supported nonrecursive cells. The reader may still decline a disjoint tagged union with a noun payload, and recursive imports containing `*` remain unsupported. It accepts an exact fork of the two loobean singletons as `?`, and each singleton separately as `%.y` or `%.n`, including inside supported faced cells. Contextual literals specialize against a loobean singleton. Open `%f`, other values, and other forks containing loobean singletons remain unsupported; recursive Hoon molds containing flags can also fail closed.

66+

67+A bare tag that provably matches no case of a known union reports the union and tag sites. This covers casts, single-argument calls, contextual unit payloads, list items and supported branch arms, including unnamed imported unions. For syntactic tuples, ordered fit replay can identify a missing tag in a nested position; an earlier mismatch or uncertainty stops the replay instead of guessing. Existing tags whose shape or payload does not fit retain the ordinary mismatch; unresolved tags stay pending.

68+

69+A change can replace uniquely named fields on a fully known, faced record spine, including through a nested wing. Replacements receive the field type as context, substitutions and pending constraints are retained, and the resulting type remains the original record. Missing fields, empty changes and definite replacement mismatches report sites; the expected-type site is the edit, since the original field declaration location is not retained. Unknown or partly unfaced spines, ambiguous fields and repeated edits remain unsupported. A cast to a known record also supplies field context to a tuple or record initializer, including nested list and union fields. The expected-type site is the cast mold; the original field declaration location is not retained. Isolated cart-style `init` and `update` expressions infer in this fragment. The complete cart-store source fails closed because store kind and declaration scope are not yet checked.

70+

71+For supported closed unions, the type printer keeps the union’s origin separate from its displayed name. It prints an in-scope name such as `msg` or `msg.lib`, including in records and gates; an accessible imported nongeneric alias may name a transitive union. A nongeneric body-local union that escapes its scope, or an origin without an accessible name, prints its cases separated by spaces, parenthesized when nested. That case-list form is print-only. A supported generic union prints its name and all arguments, including unused arguments; when its name is unavailable, the partial printer reports that limitation instead of dropping its arguments. Two faces for the same imported origin remain compatible; compatibility between distinct union origins, including in gate types, remains unsupported. Some comparisons of generic union arguments also remain unsupported rather than deciding equality or mismatch. The Hoon bridge also translates some imported unnamed unions into this representation; unsupported cases remain errors.

72+

73+Multi-argument calls form one right-nested sample: `f a b c` supplies `[a [b c]]`, with the last argument able to be a cell itself. The fragment fits the complete sample, preserving known faces and shared variables. Known sample positions can provide list or union context to arguments; unknown sample shapes use ordinary inference and some contextual forms remain unsupported. For a definite mismatch, the diagnostic points to a specific argument when it can establish which one failed; otherwise it reports the combined sample.

74+

75+A list literal can be inferred when a cast or known gate sample supplies a list type and the supplied prelude has the validated standard list definition. Empty, nonempty and nested literals work, including contextual union tags in elements; mismatched elements report the item and expected type. Imported Hoon lists share this representation. Under the same known context, `~` and zero-valued term literals fit an empty list, and a two-item unfaced cell `[head tail]` is a cons; cons cells and list literals can be nested. Mismatched heads or tails report both sites. A known list result also supplies context through complete loobean, unit-shaped and list-shaped branches, including recursive and nested branches. A known gate sample also supplies context to corresponding positions of a single tuple or record argument, including nested cells; a zero literal can therefore fit a list position. A bound zero constant still remains unsupported rather than a definite mismatch, and an unknown callee does not supply context. Uncontextualized list literals also infer with a fresh element variable, including empty and nested lists; the resulting variable can generalize. Unresolved item tags and uncertain widening remain unsupported. Faced or longer cons cells, and a missing or altered prelude list remain unsupported. For a known standard list with a supported element type, it also infers a complete two-arm branch using `~` and `[item rest]`, in either order. The binders have the element and list types and cannot shadow or duplicate names. Unknown subjects, unsupported element types, other patterns and incomplete arms remain unsupported.

76+

77+A backtick constructs a unit when the supplied prelude has the validated standard `unit` template. Its payload is inferred normally, retaining pending literals and generic variables; nested units work and the prelude’s `some` becomes available. With ordinary result annotations, its `bind`, `biff`, `both`, `clap`, `clef` and `flit` also infer. A known unit in a cast, call, list item or record field supplies its payload context, including nested units and lists; definite mismatches identify the payload and context. Unrelated union identities, some variable-dependent fits, and missing or altered prelude templates remain unsupported.

78+

79+A known union of `~` and a null-headed cell can be matched by `~` and `[~ value]` arms in either order. The payload binder is checked for shadowing. Unknown subjects, missing or duplicate arms, and unresolved branch results remain unsupported; this fragment infers the prelude’s `fall` and `need` signatures.

80+

81+A known closed union with two or more arms can be matched when each arm provably covers or excludes each remaining case. The checker first tries whole cases; when a pattern splits a case, it can expand known `?` positions into their two noun values, up to 64 alternatives across the union. Binders retain the original case type, and one arm may bind several refinements of that case. It reports missing alternatives and arms already covered, checks tags by noun value, and supports imported and generic union cases. Other partial patterns, expansions above the limit, binders spanning distinct cases, differing arm result types and some complex two-arm subjects remain unsupported. When a cast or known call sample supplies a result type, a known union subject accessed by a wing can propagate that context through whole-case arms and supported finite loobean refinements, including nested cell and list positions. Other partial-pattern context and non-wing subjects remain unsupported. The Grammar’s `step` block infers in this fragment, but its module is not yet checked.

82+

83+A known closed union can also provide context to each arm of a complete loobean or unit-shaped branch in a cast or a call with a known union sample. Nested branches and transparent groups work; a mismatch reports the expected union and the offending arm. General patterns and context through bodies with local definitions remain unsupported, and unrelated unresolved tags stay pending.

84+

85+The separate `jibb-dev/lib/jibb-import.hoon` is an unfinished reader for selected Hoon type graphs. It handles named recursion, nested map, set, queue, list, unit, jar and jug arguments, direct ordered maps, and direct `$^` unions whose source branches can be proved disjoint. It also reads ordered map fields in records when the map arguments are syntactically fixed atom molds and other fields are fixed atom molds or standard collections of static atom molds. Collection names must not be shadowed. The reader can also import a mark door sample, removing its outer sample face and validating its build subject. For a mark whose sample is exactly a named arm of its single Ford-imported `/sur` core, it can recover a source-proved nonrecursive union, including source-location wrappers around fields; recursive or unverified fallback results remain unsupported. The reader checks explicit Hoon `$%`, `$?` and `$^` unions against the Grammar’s disjointness rule, as @iko confirmed on 2026-10-30. For an explicit `$%` with distinct literal head tags, it can also prove restricted local named payload dependencies, including bare `~` fields, re-evaluate and validate each source branch, and recover the union before Hoon collapses it. The real Tlon `notes.u-note` exercises its `[%deleted ~]` case. It rejects recursive or computed dependencies, inherited same-name collisions, unsupported nested unions and proofs exceeding a shared 4,096-node budget. It re-evaluates statically recognizable source branches before Hoon can collapse them, checks materialized fork cases, and rejects shapes it cannot prove disjoint. Static records may also have verified standard-collection and `path` siblings. One direct explicit union argument in a standard list, set, map or unit is accepted when its call wrapper and collection provenance are verified and its static cases are pairwise disjoint. A synthetic regression checks that forged wrapper subjects, samples and tails are rejected. Other collection-union forms, nested ordered maps, general source-level disjointness and complete integration with the checker remain unfinished. `+golden-types-imports` can consume fixed-aura atoms, valid term singletons, Hoon's `%n` zero singleton as Jibb `~`, nested faced or unfaced cells, unions of supported, pairwise-disjoint cases, and opaque standard collections with supported arguments from caller-supplied reader results for declared `/-` imports; `+golden-types-with-marks` accepts the same shapes for declared marks. The caller must pass unchanged results from the source-aware reader: the bridge validates the supplied graph but cannot detect source cases Hoon collapsed before that graph was built. The opaque collection types retain their names and arguments for identity, unification and printing. The validated standard prelude `list` mold shares the imported list representation; other Jibb-written collection molds and most prelude collection operations remain unsupported. Other forms remain unsupported. Its disjointness proof is conservative and can reject a valid union it cannot prove disjoint. Collection recognition requires the originating `/sur` core. The reader validates direct zuse subjects and Ford subjects consisting of faced imported cores and a validated tail, checking imported cores transitively; it rejects shadowed names, inconsistent core subjects and other subject shapes. For a recursive reference, the reader matches the exact Hoon hold against named arms in validated cores, including transitive Ford imports; it rejects missing, unlabelled or ambiguous origins. Its fixtures include three real Tlon files; `tools/importer-test` compares the internal projection under eval, and the ship test compares the same golden output. `tools/type-import-test` and `tools/type-mark-test` compare bridge reports under eval and on the ship. `tools/type-tlon-test` and its ship counterpart exercise four real Tlon presence unions and a field read through the source-aware reader and partial checker. `tools/clay-fixtures` also passes Clay-built `/sur` molds and mark samples through the Clay-built importer and partial checker.

86+

87+Self-recursive `/sur` molds can cross the bridge as opaque module-and-name identities when their supported source-aware graph passes validation. Aliases, foreign references, recursive marks, unfolding, construction and field access remain unsupported; the partial printer declines recursive names that are not in scope.

88+

89+Callers that have a `/sur` core and a name can use `+read-named`: it checks for a locally declared arm before asking Hoon to evaluate the mold, and reports evaluation failures with the final Hoon trace line. `+read-mold-in` remains available when the caller already has the selected type. The opt-in `+read-named-diagnostic` and `+read-mark-diagnostic` preserve successful graphs and distinguish definite `%invalid` aura and core evidence emitted directly by the reader from `%unsupported` failures. Other failures, including unverified union disjointness and vase recognition based only on a name, remain unsupported. These entry points revalidate and re-walk failed types; the opt-in `+golden-types-with-reader-diagnostics` accepts unchanged structured reader results and reports definite aura or core errors at their imported mold use sites, when the import and supplied input are unique. Ordered replay covers direct and nested cell samples, record and function casts, and non-generic same-module aliases; it stops at an unsupported prefix, cycle or shadowing failure. Union molds, generic applications, transitive modules and unsupported reader outcomes still report generic limitations. Replay repeats inference and may add work; this entry point remains partial. Existing checker entry points continue treating failed imports as unsupported. It also fails closed on repeated field faces along an imported record spine, including recursive roots; the diagnostic remains generic. Hoon type graphs can erase unfaced nested-cell boundaries, so the check may conservatively reject a valid source with equal names in distinct erased scopes. Faced nested records and union alternatives keep separate scopes.

90+

91+The partial report can diagnose certain non-gate value dependency cycles, including cycles through gates. It requires an explicit atom or loobean result cast and a syntactically proven dependency group with unshadowed simple samples; it identifies the value and a dependency site. Untyped results, branches, nested definitions, qualified wings and complex samples remain unsupported. The proof constructs an additional dependency graph. One 24-case recursive/generic eval run took 19.7 s with it and 18.6 s before it, including startup; these single runs do not isolate the graph cost.

92+

93+The source-backed `+api-path-analysis-source` is a separate partial analysis, not an API check: it resolves reachable Jibb imports and declared mark graphs and returns path and scry segments, full and diff mark identities and their types. It also checks derived-name collisions. Full and diff payloads must be direct declared mark names; typed scry parameters must be a same-name, same-aura subset of the watch parameters, and unknown or duplicate segment binders fail closed. It creates no request gates. The caller must pass a trusted prepared prelude and unchanged source-aware reader results.

94+

95+`+golden-types-with-prelude` accepts case-local Jibb module sources alongside `/sur` and mark results and the vendored prelude source. It resolves reachable ordinary library modules in dependency order, caching completed interfaces per invocation and exporting supported closed value schemes, direct generic unions, and simple or nonrecursive generic mold aliases whose bodies the fragment supports. It detects missing sources and cycles and rejects a dependency if its interface cannot be inferred by the fragment.

96+

97+The supplied prelude is parsed into a **partial interface**: all names actually declared in the source are reserved, while only the molds and values this fragment can infer are available. These include the validated standard `list` mold, `unit`, `same`, `fall`, `need`, `lure`, `weld`, `snoc`, `turn`, `flop`, `rear`, `drop`, `skim`, `skip`, `murn`, `join` and `snip`; unsupported entries remain unavailable. The validated `list` is injected while the prelude’s gates are inferred; `weld` and `turn` use ordinary explicit result casts. An absent or altered `list` is not injected, and an altered declaration cannot leak through a direct or transitive mold alias. List-dependent prelude mold aliases remain unsupported because their templates are prepared before this injection. A named prelude union keeps the fixed `/lib/jibb/prelude/jibb` origin in every module, and its name remains unqualified when a library exports a type containing it. The prelude inventory is incomplete, so reserving the names in this source does not establish complete shadowing coverage. The source-backed internal prelude defines `poke`, which the public prelude re-exports as an ordinary transparent type. The partial checker resolves its supported source shape, preserves its public name, and rejects ordinary imports of the private internal path. An imported API with one mark and a matching direct `+$ poke` declaration can export a derived constructor and retain agent/mark metadata when the source representation has the supported agent case. Other API shapes, complete private module checking, root API and kind checking, stores, `ask`, `pure`, lowering and runtime effects remain unfinished. A possible store or root API declaring `+$ poke` reports that kind or scope needs unsupported inference; definite duplicate declarations and unrelated shadowing still report conflicts. Prepared interfaces and caches are trusted caller inputs; the future host and linker must ensure the private source validated during preparation is the same version used to lower derived constructors. A `*` payload may contain gates, so the fragment treats it conservatively; full gate-free checks are unfinished. The shared module-scope fixture compares the prepared and source-taking paths against the real prelude and a two-module golden under eval and on the ship.

98+

99+`+prepare-prelude` derives the interface and declared-name inventory from the trusted vendored source. Hosts can reuse its result with `+golden-types-with-prepared-prelude`; they must pass the unchanged result of preparation, not an independently constructed value. Empty, malformed and duplicate-name prelude sources fail closed. The source-taking `+prepare-prelude` and `+golden-types-with-prelude` do not supply the internal module; their `-and-internal` or `-with-internal` variants accept its source for the supported private import. API files, modules with `main`, unsupported definitions and many other features remain outside this subset. The older `+golden-types-with-modules` entry point fails closed for imports because it has no prelude scope. None of these partial reports claims the module has been checked.

2222

23231. **Settled: how the prelude identifies jetted functions.** On 2026-10-30, @iko said the prelude functions have working Jibb implementations, and the compiler recognizes their shapes and uses the Hoon versions so jets can fire.

24242. **Settled: how the prelude keeps helpers private.** On 2026-10-30, @iko chose a separate internal prelude module imported by the prelude, without exposing the imported helpers.

25253. **The prelude's inventory.** On 2026-10-30, @iko chose to include all names from the listed Hoon library sections, excluding groups the spec explicitly leaves out. All of 3g is included; its Hoon `tone` is exposed as `tone.hoon`, distinct from the styling type. Hoon 1c `step` is exposed as `step.hoon`, leaving the Grammar example's `step` name available. On 2026-10-30, @iko also approved `%$` as a term literal and pattern, so Jibb can write the `%$` case of Hoon `coin`. For parsing sections 4j and 4l, only the explicitly listed `slav` and `slaw` are included; other parser helpers are left out. Jibb's `not` negates a loobean, and Hoon's bitwise `not` is exposed as `not.bit`. @iko also agreed to specifying the complete exported inventory in the doc, building its types and gates needed by the examples in milestone 2, and doing native implementations in milestone 3. Prelude unions such as spaces, roles and tones need names that other modules cannot shadow. The actual inventory and signatures still need to be specified.

26−4. **Settled: a capital in a local `++`.** On 2026-10-30, @iko said it shares the enclosing `++`'s variable of that name; a different type uses a different capital. The Grammar and Decisions record this alongside the earlier aura rules.

26+4. **Settled: a capital in a local `++`.** On 2026-10-30, @iko said it shares the enclosing `++`'s variable of that name if the enclosing `++` also uses it; otherwise the local `++` introduces and generalizes its own variable. For example, `++ inner |= y=A y` shares `A` with an enclosing gate whose sample is `x=A`, but generalizes its own `A` if the enclosing `++` does not use `A`. A different type uses a different capital. The Grammar and Decisions record this alongside the earlier aura rules.

27275. **Settled: cells of no items or one.** On 2026-10-30, @iko said a single-item cell is the value and `[]` is an error. The theme's `dark=[tones=[…]]`, a record of one field, must still check.

28286. **Settled: a change with no items.** On 2026-10-30, @iko said `m()` is an error. The parser still accepts it; the checker needs to reject it and add a golden case.

29297. **Settled: the doc's blocks that aren't whole modules.** On 2026-10-30, @iko agreed to check each in its intended context: the `cmd` and `sub` definitions as prelude source, the Core language tab's `update` inside the todo island, and the Grammar's imports example against fixture files.

393917. **Settled: empty cases in union disjointness.** On 2026-10-30, @iko said `!!` is disjoint from every case. A cell containing an empty position at any depth is itself empty and is also disjoint from every case.

404018. **The two uses of Hoon `like`.** Hoon `+like` is a wet mold builder, but the gate it returns is callable and applies its supplied gate to the product. In a verified Hoon 135 example, applying `(like f)` to `[[1 2] [7 8 ~]]` produces an edge whose product is `8` when `f` is identity and `42` when `f` returns `42`; the resulting nail is the original input. Jibb molds are types, not callable values. The prelude now declares a generic `(like A)` mold and a `wonk` extractor; both parse, but their full type and backend validation remain outstanding. Should it also expose a value gate under `like`? If so, should the value preserve Hoon's input shape and behavior, or instead map the product of an already constructed edge? @iko is reviewing these alternatives; the exact public signature is not yet decided.

414119. **Settled: Hoon aura families and `step.hoon`.** On 2026-10-30, @iko chose `step.hoon` for Hoon 1c `step`, avoiding a clash with the Grammar example's `step`, and chose one-way widening across Hoon aura families: for example, `@ud` and `@ux` fit `@u`, and `@tD` fits `@t`. The reverse needs a check. The `step.hoon` group representation is not implemented yet.

42−20. **The type of Hoon `clap`.** Hoon allows its two input units and combining gate's result to have different types. If only one unit is present it returns that unit; when both are present it returns the combining gate's result. Jibb branches normally need a common type, while every union written in Jibb has a name. Should the Jibb gate require a shared type, infer an unnamed union of the possible values, or wait for a different typing design? Asked @iko on 2026-10-30. `clap` is not implemented while this is open.

42+20. **Settled: the type of `clap`.** On 2026-10-30, @iko chose one shared value type for both units and the combining gate. If either unit is absent, `clap` returns the other; if both are present, it applies the gate to their values and wraps the result.

43+21. **Settled: duplicate faces in imported Hoon records.** On 2026-10-30, @iko chose to reject an imported Hoon record with duplicate field names where its type is used. Hoon permits `[a=@ud a=@t]` and picks the first `a`; Jibb rejects it.

44+22. **Settled: overlapping imported `$%` and `$?` cases.** On 2026-10-30, @iko confirmed that the general union disjointness rule rejects imported `$%` and `$?` cases that overlap as nouns where the type is used, as it does for `$^`. The importer rejects recognizable overlaps and fails closed when it cannot verify them.

45+23. **Settled: converging explicit capitals.** On 2026-10-30, @iko chose that a body cannot force two separately written capitals to be equal. For `++ repeated |= x=(choice A A) x`, `++ f |= x=(choice A B) (repeated x)` is an error; use `A` in both positions when the type must be shared. This also applies across local captures and within generic mold applications.

46+

47+24. **Settled: how the internal prelude provides `poke`.** On 2026-10-31, @iko chose to define `poke` in the source-backed private internal prelude module and re-export it through the public prelude as an ordinary transparent type. Ordinary modules can construct and inspect its values. This settles `poke`; it does not decide the representation of `ask` or `qath`.

48+

49+25. **How the prelude provides `ask` and `qath`.** The spec calls both opaque, but Jibb has no syntax for a sealed type export. Following the decision for `poke`, @iko has been asked whether these should also be ordinary transparent types defined in the internal prelude, or whether they should retain opacity through a compiler mechanism. Their representations remain undecided.

50+

51+26. **The `step` example's `at` binder.** The Grammar's `describe` pattern `[t %sent at]` binds `at`, but the agreed prelude inventory includes Hoon's `at` from section 4b, and names may not shadow the prelude. The current incomplete prelude omits `at`, so its partial inference does not reveal this conflict. @iko has been asked whether to rename the binder, rename the prelude gate, or change the shadowing rule.

6363- `@` means any atom, independently at each occurrence. A specific atom such as `@ud` fits where `@` is expected; an `@` value needs a check to fit `@ud`. `@ud` and `@ux` also fit `@u`, and `@tD` fits `@t`, following Hoon aura families; the reverse needs a check. Distinct specific auras remain distinct. `add` takes `[A A]` and returns `A`, with an atom constraint inferred for the shared type variable.

6464- Faces are part of record types: `[a=@ b=@]` and `[x=@ y=@]` don't unify. An unnamed position can unify with a faced one and take its face, so `[0 0]` fits `[x=@ud y=@ud]`. A single-item cell `[a]` is `a`; an empty `[]` is an error.

6666- The checker infers a gate-free constraint for `eq` arguments and map and set keys and retains it when a type variable is generalized. The requirement applies recursively to nested values; union-case matching treats gates as opaque. Print a gate-free constraint as `$-([A A] ?) where A contains no gates` and an atom constraint as `$-([A A] A) where A is an atom`; separate multiple clauses with commas, as `where A is an atom, B contains no gates`.

6767- Gates may call themselves and their siblings; a non-gate value that depends on itself, even through a gate, is an error. Molds may be recursive, and "recursive molds go by name and module".

6868- A sample's mold may be left out: every bare name in a sample binds, at any depth, as in `|=(p title.p)` "when the call fixes the type", `|= [a=@ b]` and `|=(m ~)`.

116−- Signatures change where the Prelude table says: maps and sets are plain gates over Hoon's trees, as `(get.by m k)`; folds take a start, as `(roll xs init f)`, `rep.by` and `rep.in`; ordered maps go through lull's `on`, as `(get.on lte m k)`.

116+- Signatures change where the Prelude table says: `clap` takes two units of one value type and a combining gate over that type; maps and sets are plain gates over Hoon's trees, as `(get.by m k)`; folds take a start, as `(roll xs init f)`, `rep.by` and `rep.in`; ordered maps go through lull's `on`, as `(get.on lte m k)`.

117117- Left out: signed and float gates, parser helpers outside 3g other than the explicitly listed `slav` and `slaw`, and the table's "The rest" (1b, 2p, 3d, 3f, 4c, 4n, 4o, 5a–5f); "`jam`, `cue` and `fein` run inside the runtime".

118118- Write the prelude in Jibb, enough to give every name its type. Foundational gates use private low-level primitives from the internal prelude module. Jetted functions have working Jibb implementations; the compiler recognizes their shapes and uses the Hoon versions so jets can fire. They may take gates as arguments; the Nock backend comes in milestone 3.

119119- Element signatures are in the Layout and styling table. Paths and unchecked cords have separate declarations, with `link-unsafe`, `image-unsafe` and `go-unsafe` for the unchecked forms. Both navigation declarations produce `[%go url=@t]`; `go` converts its application path to a cord including the app's base path. "The same attribute twice in a literal list is an error."

121121**Errors**

122−- Each one the Grammar tab describes needs a golden case with its message. A start on the list: an aura mismatch; mismatched faces; "msg has no case %submitt"; an unresolved tag, as the Grammar's `add-button` ("nothing fixes the union of %add"); an open constraint at the end of a module; a `|=%tag` whose union has no such case tagged at its head; a union whose cases overlap; a missing `?-` case, named; an arm that earlier arms cover; a value that refers to itself; a shadowed name, including a prelude or imported one; a cell in `{…}` with no printer; an atom of a generic aura in `{…}` or a path's `(…)`; a capital that a body makes a `@ud` or a list; `~[text "hi"]`, where the checker suggests `~[(text "hi")]`; clashing derived names; an import cycle; from an import, a signed or float aura, a core, gate or vase, or a `$^` whose cases don't differ as nouns, each where used; a `(facts …)` outside an API file's `paths`; a gate in island data or a model, naming the field; a repeated attribute in a literal list. Read the Grammar tab, and the other tabs' mentions of "error" and "the checker", and make the list complete.

123123- For a `+$` whose cases overlap or do not fit, suggest that a record or tuple leaves its `[` open on the `+$` line. `+$ pt` above `@t` and `[@ud @ud]` is a valid union.

124124- "Each error names both conflicting sites, with excerpts." Today's `error` is `[file line col msg]`, a start only; spans keep each node's end so that a type error can underline both sites.

125125- Messages name things in the doc's words and quote the code they're about in backticks, as milestone 1's do. Their wording is fixed by the golden tests once written.

Tags take their union from context, as Tag resolution describes. Cases must differ as nouns: inhabited cases must differ at some position of their right-nested cells, where one is an atom and the other a cell, or both are different constants. `*`, type variables and molds that can be either, such as `(list A)`, can overlap atoms and cells. `?` counts as the two atoms `%.y` and `%.n`: it is disjoint from cells and overlaps the constants 0 and 1. The empty mold `!!` is disjoint from every case; a cell with an empty position at any depth is itself empty and is also disjoint from every case. A union whose cases don't all differ is rejected.

An initial inference fragment and a standalone Hoon type reader are being tested. The fragment explicitly reports that it does not check a module; partial bridges pass selected Hoon atoms and unfaced cells from `/sur` molds and marks into inference. The reader handles mark samples, recursive molds whose origins can be verified through Ford imports, nested collections, direct ordered maps, certain ordered-map fields, and direct `$^` unions whose cases can be proved disjoint. Ambiguous recursive origins fail closed; nested `$^`, other nested ordered maps, general union disjointness and complete import integration remain unfinished. The partial checker resolves a subset of ordinary library imports in dependency order using supplied Jibb sources and the current prelude names, and detects missing sources and cycles. It does not yet check API or kind semantics, and the prelude inventory is incomplete. The inference fragment supports unrestricted `@`, selected one-way widenings including aura-family ancestors, generalized atom constraints arising from explicit capitals or bare sample binders, acyclic local value definitions with captures, and simple acyclic local mold aliases. Unfixed decimal literals default to `@ud` in gate-free inferred types; recursive local groups, more complex local molds, other constraint cases and defaulting inside gate types still need work. Collection recognition checks the originating core and fails closed on shadows or unsupported Ford subject shapes; its golden fixtures include three real Tlon files. The prelude currently has only a few functions, and [prelude-inventory.md](prelude-inventory.md) is a source audit, not the complete inventory or signatures. The milestone remains unfinished.

22+The repository spec records the subsequent type-system and prelude decisions; those changes also need synchronization to the Claude document. An initial inference fragment and a standalone Hoon type reader are being tested. The fragment explicitly reports that it does not check a module; partial bridges pass Hoon `*` in supported nonrecursive molds, selected Hoon atoms, term singletons, the null singleton, the two loobean singletons and their exact fork, nested faced or unfaced cells, supported disjoint unions and opaque standard collections from `/sur` molds and marks into inference. Collections retain their names and supported arguments for printing and unification; nested supported union arguments are retained too. The bridge trusts unchanged results from the source-aware reader; a materialized type graph alone cannot reveal cases Hoon already collapsed. The source-validated standard prelude `list` mold shares this representation with imported lists; other Jibb-written collection molds and most prelude collection operations remain unsupported; malformed names and arities fail closed. Selected self-recursive `/sur` molds cross as opaque module-and-name identities; aliases, foreign references, recursive marks, unfolding and construction remain unsupported. The reader handles mark samples, including a source-proved nonrecursive union from a single Ford-imported `/sur` core, recursive molds whose origins can be verified through Ford imports, nested collections, direct ordered maps, certain ordered-map fields, direct `$^` unions whose cases can be proved disjoint, and one verified explicit union argument in a list, set, map or unit. Tagged `$%` cases can additionally use restricted local named payload molds and bare `~` fields, as in the real Tlon `notes.u-note`, with a bounded source proof; unsupported or ambiguous dependencies fail closed. Ambiguous recursive origins fail closed; recognizable explicit unions are checked from source before Hoon can collapse their cases, as @iko confirmed for imported `$%`, `$?` and `$^`, while other nested unions, nested ordered maps, general union disjointness and complete import integration remain unfinished. Opt-in structured reader APIs preserve successful graphs and distinguish definite unsupported-aura and core evidence from failures the reader cannot prove; unverified union disjointness and name-only vase recognition remain unsupported. They revalidate and re-walk failed types. An opt-in partial checker entry point consumes unchanged reader results and reports definite aura or core errors at imported mold use sites when their inputs are unique. Ordered replay covers nested cell samples, record and function casts, and non-generic same-module aliases; unsupported prefixes, cycles and shadowing stop it. Union molds, generic applications, transitive modules and unsupported reader outcomes remain generic. Replay repeats inference and may add work. The partial checker resolves a subset of ordinary library imports in dependency order using supplied Jibb sources and a source-derived partial prelude interface, caches completed interfaces per run, and detects missing sources and cycles. The source-backed internal prelude defines `poke` and the public prelude re-exports it as a transparent type. The partial checker resolves its supported source shape and rejects ordinary imports of the private path. An imported API with one mark and a matching direct `+$ poke` declaration can export a constructor and retain agent/mark metadata when the representation has the supported agent case. A separate partial analysis resolves supported API path declarations and their full and diff mark types, including the todo paths; it does not create requests or check an API module. Complete private module checking, other API shapes, request gates, root API and kind checking, stores, `ask`, `pure`, lowering and runtime effects remain unfinished. A possible store or root API with `+$ poke` reports unsupported kind or scope, while definite duplicates and unrelated shadowing still report conflicts. The prelude inventory is incomplete. The inference fragment supports unrestricted `@`, selected one-way widenings including aura-family ancestors, generalized atom constraints arising from explicit capitals or bare sample binders, acyclic local value definitions with captures, selected single self-recursive top-level and local gates, simple and nonrecursive generic mold aliases, selected faced record casts and field reads, and contextual tags, `~` and constructors for closed disjoint unions, including direct nonrecursive generic unions and propagation through complete loobean and unit-shaped branches in casts and known union-sample calls, including nested branches. Multi-argument calls form a right-nested sample, retain known faces and shared type variables, and can use known sample positions to contextualize list and union arguments. A definite mismatch points to the failing argument when the fragment can establish it, otherwise to the combined sample; unsupported contextual forms still fail closed. For a supported recursive gate, the checker infers the sample first and uses its exact type, including field faces, for one monomorphic self reference. It generalizes after the body is checked; subsequent uses instantiate it independently. Incompatible recursive arguments can report the gate and argument sites. For a complete loobean branch with one direct self-call arm, a separately inferred closed base type can seed the recursive result before the whole body is checked. Open or pending base types do not seed it; other branch shapes remain subject to the fragment’s existing limits. A supported single local recursive gate also uses a monomorphic self reference and generalizes variables free of the enclosing environment after checking its body; captured variables remain shared. The checker collects written capitals per `++` before inference, excluding nested definitions: a capital used in an enclosing definition is shared with its locals even when written later, while a capital introduced only in a local definition is generalized there. Sibling locals can introduce independent capitals with the same spelling; generic mold parameters keep their own scope. Top-level groups of syntactic gates are inferred together with monomorphic placeholders and shared substitutions, then generalized only after the whole group checks; downstream uses and library interfaces instantiate those schemes independently. A dependency graph identifies groups with two iterative depth-first passes; its conservative local-reference edges can reject otherwise valid programs. Supported local mutually recursive gate groups also use shared monomorphic placeholders and generalize only after the group checks, preserving captured outer variables. A bounded dependency proof reports certain non-gate cycles through values and gates when an explicit atom or loobean result cast and simple unshadowed expressions establish the cycle. Other mixed gate/value cycles, polymorphic recursion, unresolved literal constraints and unresolved branch joins remain unsupported. Reporting repeats inference for a single recursive gate outside a group; grouped reports use the stored schemes. Its performance cost remains unmeasured. A single-arm cell pattern accepts two or more binders, the last capturing the remaining tail; duplicate and shadowed binders are rejected. Intermediate union or collection tails, nested patterns, wildcards and faced records remain unsupported. String interpolation accepts known atom auras, unrestricted `@`, tapes and isolated decimal literals; a known cell asks for a printer, and an explicitly generic atom asks for an aura. Loobeans, term singletons, non-tape collections, open types and a type fixed only later remain unsupported. A known closed union with two or more arms supports patterns that provably cover or exclude each remaining case, including payload binders, imported and generic cases, and binder-free catch-alls. Partial boolean patterns can split known `?` positions into their two noun values, up to 64 alternatives across the union; binders retain their original case type. Missing alternatives and covered arms are reported. Other partial patterns, expansions above the limit, binders spanning distinct cases, differing arm result types and some complex two-arm subjects remain unsupported. A cast or known call sample can supply result context through whole-case arms and supported finite loobean refinements for a known union accessed by a wing, including nested cell and list positions; other partial-pattern context and non-wing subjects remain unsupported. The Grammar’s `step` block infers in this fragment, but its module is not yet checked. A bare tag proved absent from a known union reports the union and tag sites in casts, single-argument calls, unit payloads, list items and supported branch arms; imported unnamed unions print their cases. Ordered fit replay can identify a missing tag nested in a syntactic tuple, stopping at an earlier mismatch or uncertainty. Known faced records support uniquely named field changes, including nested wings, with field context passed to replacements and the original record type retained. Missing fields, empty changes and definite mismatches report sites; the expected-type site is the edit because the original field declaration location is not retained. Unknown or partly unfaced spines, ambiguous fields and repeated edits remain unsupported. A known record cast supplies field context to its tuple or record initializer, including nested list and union fields; mismatch diagnostics use the cast mold because the original field declaration location is not retained. Isolated cart-style `init` and `update` expressions infer, while the complete cart-store fails closed because its kind and declaration scope remain unchecked. Uncontextualized list literals infer a fresh element type, including empty and nested lists, with independently generalized uses. Unresolved item tags and uncertain widening remain unsupported. Backtick unit construction uses the validated standard prelude unit template, infers its payload without losing pending constraints, and makes the prelude’s `some` available. Ordinary result annotations also let its `bind`, `biff`, `both`, `clap`, `clef` and `flit` infer. A known unit in a cast, call, list item or record field supplies context to its payload, including nested units and lists; mismatches identify the payload and context. Unrelated union identities, some variable-dependent fits, and missing or altered prelude unit templates remain unsupported. Contextual null-headed cells fit their cases, but do not supply a `|=%$` constructor; unresolved nulls remain pending and are reported separately from tags. A known union of `~` and a null-headed cell supports a complete `~` / `[~ value]` branch in either order, including shadow checks; unknown subjects, missing or duplicate arms, and unresolved branch results remain unsupported. This fragment infers the prelude’s `fall` and `need` signatures. With the validated prelude list and a known cast or gate sample, empty, nonempty and nested list literals infer their element types, including contextual union tags; a mismatched element names both sites. In that context `~` and zero-valued terms fit an empty list, and two-item unfaced cells form cons lists, including nested cons and imported-list contexts; invalid heads or tails name both sites. A known gate sample also supplies context to matching positions in a single tuple or record argument, including nested cells; zero literals can fit list positions. A bound zero constant remains unsupported rather than a definite mismatch, and an unknown callee does not supply context. Faced or longer cells and a missing or altered prelude list fail closed. A known list result also supplies context through complete loobean, unit-shaped and list-shaped branches, including recursive and nested branches. For a known standard list with a supported element type, a complete `~` / `[item rest]` branch infers the element and tail types in either arm order and checks binders for shadowing. Unknown subjects, unsupported element types and other or incomplete list patterns remain unsupported. A value with type variable `A` can fit a field whose type is that same `A`, including in generic union payloads and nested or repeated record fields. Other variable-dependent face merges remain unsupported. Forced equality of distinct written capitals now reports both source sites, following @iko’s decision; forcing one to a concrete type remains unsupported. Imported record spines with repeated faces fail closed where used, but only with a generic unsupported diagnostic. Hoon may erase unfaced nested-cell boundaries, so the check can conservatively reject valid names in distinct erased scopes. Supported closed unions print using an in-scope name or imported alias; an unnamed nongeneric union prints its cases, parenthesized when nested. The latter is print-only. Generic union types retain all arguments in their printed name; if that name is unavailable, the partial printer reports the limitation. Different import faces for the same origin remain compatible; compatibility across distinct union origins and some generic-argument comparisons remain unsupported. Nonrecursive generic aliases can reorder, repeat or omit parameters while retaining a union’s origin, including through local scopes and library interfaces. A generic union declared directly inside a body remains unsupported, as do differing-variable face constraints in a union payload. A transitive generic union whose name is unavailable is reported as unsupported instead of hiding its arguments. Unfixed decimal literals default to `@ud` in gate-free inferred types; recursive molds, general branch tag context, other constraint cases and defaulting inside gate types still need work. Collection recognition checks the originating core and fails closed on shadows or unsupported Ford subject shapes; a wrapper regression also rejects forged subjects, samples and tails. Its golden fixtures include three real Tlon files. A Clay test passes a Ford-built nested union through the reader into partial inference. The partial prelude includes `murn`, `join`, `snip`, `rear` and the newly agreed shared-type `clap`, parsed but still awaiting checker and backend validation, and [prelude-inventory.md](prelude-inventory.md) is a source audit, not the complete inventory or signatures. The milestone remains unfinished.

23+

24+The shared prelude interface reserves every name present in the supplied vendored source and makes only supported inferred entries available, including `list`, `unit`, `same`, `fall`, `need`, `lure`, `weld`, `snoc` and `turn`. The validated standard `list` mold is injected when the prelude’s own gates are inferred; `weld` and `turn` have ordinary explicit result casts. An absent or altered `list` is not injected, and an altered declaration cannot leak through direct or transitive mold aliases. List-dependent prelude mold aliases remain unsupported because their templates are prepared before injection. Unsupported entries such as most list helpers remain reserved but unavailable; backend validation of the helpers remains outstanding. All callers use the same prelude origin, so a library can export a type containing unqualified `(unit A)` to another module. Preparation rejects empty, malformed, conflicting or import-bearing source; the prepared value is trusted and must come unchanged from `+prepare-prelude`. The module-scope fixture compares the prepared and source-taking paths against the real prelude and a two-module golden under eval and on the ship. The source and checker remain incomplete, so this does not establish complete shadowing coverage or a checked module.

4345- Two independent audits before 7c739b7, one of which compared the library with a reference parser written in Python from the doc over about 19,000 generated programs. Before ab797a9, a second Python parser, written from the decisions, agreed with the library on 8,000 generated programs and 900 hand-written probes.

4446- Speed: starting `urbit eval` and building the library takes about 8 s. After that, a 2,000-line module of 400 definitions parses in about a second. Loops over definitions, arms, lines and items grow no stack; nesting costs a few stack frames a level, and 100,000 nested brackets still parse (library section 3).
