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 two-binder cell pattern, 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. Local mutual groups, polymorphic recursion, value cycles, 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.

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.

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. Some proven non-gate value cycles are diagnosed; other 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. Literal heads compare by their runtime noun, so `|=%$` can construct an explicit null-, loobean-zero- or term-zero-headed case. Equal heads with distinct payloads can be selected when exactly one payload fit is proven; unknown or ambiguous alternatives remain unsupported. 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. Generic unions declared directly inside a body and recursive molds outside the source-proven slices described below remain unsupported. A directly known named union can instantiate an unconstrained generic gate sample while retaining its origin, generic arguments and faces. Unnamed, pending-tag, recursive, unknown-atom and variable-bound union origins 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. 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.

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+A direct unshadowed prelude call can use checked source layouts when a positional argument is a directly named, already inferred root gate. For two-slot function samples, the checker can match a named update against an unnamed generic gate sample without confusing a binder face with a nested record face. Both explicitly named slots must agree; source boundaries are evidence for this fit, not a call-arity rule. The source gate and prelude annotation must be available from their checked bindings. Local or dynamic gates, aliases without direct evidence, recursive or SCC placeholder bodies, other sample shapes and unresolved call-sample variables remain unsupported by this proof. Ordinary inference remains the fallback.

62+

63+The checker retains a per-analysis index of finalized root gates and a prelude source table bound to the entire trusted prepared interface. A dependency screen avoids building the table when the root cannot use it; changing the interface invalidates it. The host remains responsible for supplying a prepared interface paired with its source. The matcher checks each slot and product in both directions with a shared substitution. Before returning its tentative proof it requires both complete call samples to normalize to closed, tag-free types, then repeats every slot check and requires the substitution and fresh-ID counter to remain unchanged. This keeps later argument or enclosing constraints from invalidating an earlier face check, and preserves pending constraints, capital checks and projection evidence. These scans and the bounded second proof add work; they do not establish a global linear-time bound.

64+

65+Before the empty-capital optimization below, single sequential eval runs including startup showed that 2,000 ordinary gates used 70.20 seconds of user CPU at baseline and 70.64 seconds with the cached source table. Fifty unsupported eligible scalar-slot calls used 24.75 and 25.71 seconds, while fifty function-slot failures used 24.15 and 25.36 seconds. Fifty successful calls took 26.56 seconds before the final stability replay and 26.99 seconds with it. These are synthetic measurements, not production performance limits.

66+

67+Restricted-number promotion only applies to written capital variables. If none are present, it returns immediately instead of traversing the environment. In one startup-inclusive pair of runs on 2,000 independent gates, output was byte-identical and user CPU fell from 71.67 to 38.26 seconds; wall time was 72.80 versus 51.66 seconds while other checks were running. This does not establish a bound for dependent modules or a complete-checker benchmark.

68+

69+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. For a known non-union cell, a separate one-arm rule also accepts structured patterns, including nested literal and wildcard positions, when the existing coverage proof establishes the whole pattern. It binds payloads with their original types and checks result context; unknown, partially covered, union or recursive spines stay unsupported.

6070

6171String 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.

6272

73+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 loobean literals specialize against a matching singleton by noun, including a proven singleton in a direct union; named loobean singletons do not silently widen to a distinct aura. Open `%f`, other values, and other forks containing loobean singletons remain unsupported; recursive Hoon molds containing flags can also fail closed.

74+

75+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.

76+

77+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.

78+

6379For 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.

6480

6581Multi-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.

6682

67−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 zero nested inside a single tuple argument where a list is expected also remains unsupported, rather than a definite mismatch; separate call arguments can receive list context. Faced or longer cells, uncontextualized construction, 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.

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. Known loobean result context can propagate through supported complete branches and binder-only cell arms, with a final directional fit; a binder-only arm over a union subject remains unsupported. A known gate with an unresolved result variable can also receive an enclosing result type before its argument is inferred, for example allowing `^- (list @t) (id ~)`; unknown callees and unresolved targets retain the conservative path. A known gate sample 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.

84+

85+A term-headed pair such as `gap+%s2` follows the same contextual inference as `[%gap %s2]`; its synthetic head uses the pair’s span in diagnostics.

86+

87+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.

6888

6989A 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.

7090

71−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; contextual union-pattern branches also remain unsupported. The Grammar’s `step` block infers in this fragment, but its module is not yet checked.

When a cast or known call sample supplies a result type, a known union subject accessed by a wing, a grouped wing or a supported shallow call can propagate that context through whole-case arms and supported finite loobean refinements, including nested cell and list positions. Other partial-pattern contexts and subject forms remain unsupported. The Grammar’s `step` block infers in this fragment, but its module is not yet checked.

7292

7393A 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.

75−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 `$^` unions whose source branches can be proved disjoint. It also reads ordered map fields in records when the map arguments are syntactically fixed atom molds and other fields are fixed atom molds or standard collections of static atom molds. Collection names must not be shadowed. The reader can also import a mark door sample, removing its outer sample face and validating its build subject. The reader checks explicit Hoon `$%`, `$?` and `$^` unions against the Grammar’s disjointness rule, as @iko confirmed on 2026-10-30. 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, 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/clay-fixtures` also passes Clay-built `/sur` molds and mark samples through the Clay-built importer and partial checker.

95+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 `$^` unions whose source branches can be proved disjoint. It also recognizes a direct ordered-map call with two simple named mold operands, as in Tlon `notes.log`, after validating provenance and operand source; revisiting the same map hold fails closed. It also reads ordered map fields in records when the map arguments are syntactically fixed atom molds and other fields are fixed atom molds or standard collections of static atom molds. Collection names must not be shadowed. The reader can also import a mark door sample, removing its outer sample face and validating its build subject. For a mark whose sample is exactly a named arm of its single Ford-imported `/sur` core, it can recover a source-proved nonrecursive union, including source-location wrappers around fields; recursive or unverified fallback results remain unsupported. The reader checks explicit Hoon `$%`, `$?` and `$^` unions against the Grammar’s disjointness rule, as @iko confirmed on 2026-10-30. For an explicit `$%` with distinct literal head tags, it can also prove restricted local named payload dependencies, including bare `~` fields, re-evaluate and validate each source branch, and recover the union before Hoon collapses it. The real Tlon `notes.u-note` exercises its `[%deleted ~]` case. A bounded fallback also recovers one level of local named tagged unions inside such a union, including Tlon `notes.u-notebook` and `notes.u-notes`. Source-proved tagged unions can also be wrapped in Hoon `$~` defaults, including a downstream union using Tlon `epic.saga`; the selected source and projected branches still undergo the same provenance and disjointness checks. The tagged-source helper peels up to four consecutive default wrappers, while default wrappers encountered inside dependency proofs consume the existing semantic-node budget. A source-proved nested self-recursive union retains its named owner, including Tlon `notes.import-node`; deeper, mutually recursive or unproven cases stay unsupported. The nested source proof has a 256-visit semantic-node budget, and source-location wrapper peeling is limited to four per node; Hoon evaluation and source scans are not metered. 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.

97+An import-free Jibb library can export an opaque single-parameter recursive identity when its source has exactly two distinct term-tagged cases: a text leaf and a node containing `(list (name M))`, optionally with one `$-(@t M)` event field. A module-local index records the exact parsed source, defining path and prepared prelude interface; it is shared across that module's inference passes, and its canonical `list` must be source-backed. The normal resolver publishes an interface only after all ordinary mold and value checks succeed. Same-origin aliases retain the defining identity and independently instantiate type arguments; distinct origins remain unsupported. The opaque identity is conservatively treated as gate-bearing for numeric defaulting, and gate-freedom remains unknown. Explicit literal-headed construction uses a source-proven one-layer view: the event result receives the existing type argument and recursive children keep the defining identity. It consumes the existing shared 256-step recursive inference budget, and a per-view 4,096-visit guard bounds the new face and substitution scan; longer scans decline. These bounds do not cover parsing, existing inference, atom sizes or repeated attempts. One startup-inclusive, shared-load comparison of 100 valid and 100 invalid source definitions took 29.67 s wall / 25.14 s user CPU before this slice and 33.47 s / 26.99 s with it; the former declined all 200 while the latter inferred the valid definitions. These single runs are not a production benchmark. Two-arm matches over explicit source tags and flat binder or wildcard fields use that same one-layer view and existing binder, coverage and branch checks; a single-arm match on a direct in-scope wing can report its missing case. Recursive children retain their nominal type and arguments. Subject recognition and view validation can each scan substitutions, and the scan cap applies separately to each attempt. In one separate startup-inclusive comparison of 100 valid and 100 invalid source matches, the construction-only checker took 30.18 s wall / 29.31 s user CPU and declined all 200, while the pattern slice took 28.28 s / 27.69 s and inferred or diagnosed them. These single shared-load figures are not production benchmarks. General structural fits, catch-all and nested patterns, recursive source with imports and local recursive molds remain unsupported; the test tree does not prescribe the eventual `element` representation. Caller-supplied detached interfaces and caches retain the existing trusted-input contract.

98+

99+Self-recursive `/sur` molds can cross the bridge as opaque module-and-name identities when their supported source-aware graph passes validation, including one-argument lists containing same-origin recursive references. The real Tlon `notes.import-node` reaches this bridge; it does not unfold or construct the recursive type. Aliases, foreign references, recursive marks, unfolding, construction and field access remain unsupported; the partial printer declines recursive names that are not in scope.

100+

101+The partial checker also recognizes a source-proven Jibb recursive mold consisting of `~` and one faced cell with a fixed-aura head and direct self tail. Its identity includes the defining path and name. It unfolds this shape for supported null and cell construction and for a two-arm null/cell match; static application-path literals use the verified public `qath` alias. The internal prelude defines `qath` as a transparent knot sequence and the public prelude re-exports it. Each inference attempt has 256 unfolding and static-segment steps; parsing and separate retries are not bounded by that limit. Dynamic application-path segments, broader patterns and other recursive shapes remain unsupported. Route and static-file existence checks remain milestone 4.

102+

103+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` 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, core or proven union-overlap 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.

104+

105+For supported source-aware Hoon `$?` unions, the reader can prove a definite overlap by independently evaluating and projecting the original cases, verifying each projected head against its source tag, and finding a shared runtime noun in a pair. Its positive witness traverses faces, named nodes, forks, cells, supported atom forms and `*`; `!!`, opaque references, applications and unproved aura intersections cannot themselves establish a witness. It compares singleton noun values independently of aura, and requires inhabited positions throughout a cell. Unknown or exhausted proof remains unsupported, while existing disjoint-source recovery still handles proven distinct cases. The source screen admits at most 128 cases and 4,096 raw noun nodes; dependency checking and the pair/type witness each have their own 4,096-node budget. Hoon evaluation, projected-graph validation, chapter lookup, atom byte sizes and other type-graph walks remain outside those budgets. The error points at the Jibb use; source case locations are unavailable. This is a partial named-reader analysis, not general imported-union checking or a mark-reader overlap diagnostic.

77−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.

107+In single startup-inclusive runs of eight Hoon reads, a benign three-case union used 37.78 seconds of user CPU with the earlier narrow witness and 39.99 seconds with the structural witness; a repeated-head union used 39.84 and 40.97 seconds. Other checks ran concurrently, so these measurements do not establish a production bound.

78108

79−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.

109+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.

81−`+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.

111+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.

82112

83−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` and `turn`; unsupported entries, such as most list helpers, 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. Prelude imports, including the planned private internal module, are not supported by preparation. 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.

113+`+api-path-evidence-source` retains that analysis with the API source, complete prepared prelude (including reserved names), supplied reader results and resolved Jibb dependency cache. `+api-path-watchability` classifies a unique declaration as watchable or not watchable, or reports unknown when evidence is absent or ambiguous. The artifact and reader results are trusted host inputs; the host must bind them to the source versions used later. This is declaration evidence, not proof about an arbitrary request value, a checked API module, a runtime validator or an island watch.

84114

85−`+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, duplicate-name or import-bearing prelude sources fail closed. `+golden-types-with-prelude` remains the source-taking wrapper. 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.

115+For a unique supported declaration, `+api-request-parts` retains that evidence with the typed path parameters in source order, the full-state reply sample, and a fold type when there is one diff mark. The fold takes the tagged diff and previous full state and returns full state. Missing or ambiguous evidence, unsupported parameter auras and multiple-diff folds fail closed. These are components for a future request gate; they do not yet fix its argument order, construct a request, or prove watchability of a value.

116+

117+`+api-support-analysis-source` additionally infers supported ordinary API molds and values, resolves every declared mark, and retains their source, dependency and path evidence. Unsupported helpers or marks fail closed. An unused `/-` core is not independently validated, ordinary definitions that need derived gates remain unsupported, and this result is not a checked API interface or an exported request.

118+

119+The ordinary import resolver can infer derived request-gate types for multiple supported API paths. A case may take one typed path parameter before its reply gate, or one diff fold after the reply; a case with both, multiple parameters or diffs, or a separate scry path remains unsupported. Each reply maps the full mark type to a fresh `M` and the request result is `(ask M)`. Checked ordinary API values and molds, declared mark molds and a supported poke constructor are exported too. Every selected `/sur` core must have a directly used, successfully read mold; unselected core bindings are not independently validated, and Jibb module imports remain unsupported in this API fragment. The unchanged todo API fits this fragment.

120+

121+A call whose direct result is a known named generic union can receive a matching same-origin, same-arity result context before its arguments are inferred. This retains the ordered generic arguments and existing capital checks; pending tags, recursive or variable-bound origins and unrestricted atom cases remain conservative. Constructor fitting reports unsupported when an unresolved or opaque case could contain the requested tagged head. It keeps definite missing-case errors for proven nonmatching cases, including an explicitly atom-only faced head. The real todo callback `|=%got` can infer when an `(ask msg)` result context fixes its message union; the uncontextualized call remains unsupported.

122+

123+A two-item tuple with an explicit term, null or loobean head can receive payload context from a known union when every alternative is a literal-headed cell and its head noun is unique. The payload must be a direct wing-headed call, optionally grouped, with literal, wing or constructor arguments. The checker first retains the original inference if it already fits; otherwise it tries the contextual path once and fits the selected case and enclosing union. It declines this path if any substitution has a structural root, because a caller may have walked away variable provenance. Duplicate heads, opaque competitors and other shapes also stay conservative. The guard scans the substitution for each eligible tuple and may perform one extra shallow inference; it does not guarantee globally linear work. This lets an explicitly typed todo subscription body infer; it does not check an island or prove request watchability.

124+

125+`+gate-free-type` is a separate three-way proof over normalized checker types: it reports a gate-free result, a gate-bearing witness with its field path, or unknown. It tracks conservative inhabitance before reporting a gate in a cell, spends one shared node budget, and treats opaque recursion, open variables, unknown collection forms and `*` conservatively. Source-proven `qath` and the recognized list/unit representations have dedicated proofs. `+gate-free-mold-source` parses and resolves one named mold with a fresh active-root graph, retaining the complete prepared prelude, source bundle, trusted reader inputs, dependency cache and inferred mold. It caps classification at 256 nodes; parsing, import resolution and type inference are not covered by that cap. The host must canonicalize paths and bind trusted sources and reader results to their versions. API, store and private roots decline; other definitions and unused imported Hoon bindings are not fully checked. This is mold analysis, not a module, kind, island, watchability or runtime check, and it does not infer general gate-free constraints.

126+

127+Each case's canonical API identity and source-derived schema travel across imports in a nonrecursive graph certificate containing the exact source bundle, prelude, reserved scope and trusted reader results. Cached interfaces must match those inputs and cannot hide an active ancestor; unknown legacy entries are rebuilt from their unique supplied source. Request-bearing closures are limited to 256 paths and requests. Closed gate samples can also fit when an unnamed input slot corresponds to a named one, provided products are identical and nested value faces and ambiguous cell tails remain intact. This is type inference only: request lowering, runtime schema validation and value watchability proofs are not implemented.

128+

129+`+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. Qualified wings can also read nested fields of an imported value, instantiating that value’s scheme independently at each use; missing, ambiguous and non-record fields remain unsupported.

130+

131+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`, the doc-exact generic `cmd` union, `same`, `fall`, `need`, `bond`, `lure`, `weld`, `snoc`, `turn`, `lent`, `zing`, `flop`, `rear`, `drop`, `skim`, `skip`, `murn`, `join`, `snip`, `levy`, `lien`, `cork`, `corl`, `cury` and `curr`; 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. The same validated template is available when prelude mold aliases are prepared, so supported direct and transitive aliases can use it. 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. A dedicated trusted internal-prelude preparation path also supplies private comparison and arithmetic schemes for the Jibb-written `gth`, `add` and `dec` wrappers. Ordinary module resolution rejects that primitive path even if a caller supplies a spoofed root or bundle. The low-level prepared interface is still trusted host input; the host must select the vendored sources and canonicalize paths. Primitive execution and shape-based jet recognition are not implemented. The Jibb-written `lth`, `gte` and `lte` gates compose the source-backed `gth` and `not` gates; supported calls infer a shared atom constraint and return `?`. Their execution and jet recognition await the backend. The source-backed `add` and `dec` wrappers use private arithmetic interfaces whose shared atom variable excludes loobeans; the partial checker preserves that constraint through supported inference and prints `where A is an atom other than ?`. The partial checker resolves the supported `poke` source shape, preserves its public name, and rejects ordinary imports of the private internal path. The Jibb-written `lent` recursively counts a list using `add`; the partial checker infers its generic list argument and `@ud` result. Its execution and jet recognition remain unverified until the backend exists. The Jibb-written `zing` concatenates homogeneous lists in order using `weld`; the checker infers `(list (list A))` to `(list A)`, including for gate elements. Hoon `zing` also accepts heterogeneous noun lists, which this type does not express. `tools/hoon --raw -f tools/testdata/zing-hoon-reference.hoon` compares an equivalent Hoon recursion with Hoon `zing` on selected finite inputs; it does not execute Jibb or verify lowering or jet recognition. 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, complete `ask` and `pure` checking, 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.

132+

133+`+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.

146+The internal prelude defines transparent `(ask M)` cases for pure, agent and store requests; the public prelude re-exports it and defines `pure` in Jibb. Preparation supplies the private module with `list.core` and `unit.core` only from validated canonical public templates. If a template is unavailable, an isolated check validates the private molds, but only molds independently inferred against the actual available templates enter the interface. The partial checker infers supported constructors and exhaustive matches; absent versus present-zero state remains distinguishable. Agent and store receiver fields carry raw nouns and cannot prove schema validity or watchability. The public prelude also defines the documented `sub` union in Jibb; supported watch payloads retain the public `(ask M)` type. A `sub` value is not itself proof that its request is watchable. Generated decoders, source-bound runtime validation, request lowering, other derived request shapes and island watch checks remain unfinished. Public prelude preparation is partial: consumers must verify that `ask` was actually exported with its source origin.

Fixed, reordered, repeated and phantom generic aliases remain unsupported where a safe public name cannot be recovered; a fixed nongeneric alias is not printed as though it accepted type arguments.

149+

150+The partial checker reserves `proj` in module, local, sample, pattern and import bindings, including bindings inside unsupported source; a field, tag or path segment may still have that spelling. With a known expected record type, it checks selected explicit `(proj record)` calls over closed, uniquely faced records, preserving the source expression, its type, the result type and field axes in the checked interface. Imported and private-prelude dependencies retain the source needed to lower those plans. The checker does not yet lower or execute them. It supports selecting one or more fields in their original order; a single selected field keeps its face and uses one source axis. Reordered fields, unknown or open record spines, some nested contexts and recursive groups with projections remain unsupported. A directional fit of a wider faced record fails closed instead of inserting a projection, including within supported list, unit and record positions. To limit repeated work, record-spine proofs are reused along the same closed spine and stop at 1,024 fields; field boundaries and the special handling of positional calls reset the appropriate proof. Prepared interfaces and their source remain trusted host inputs.

96152## The tree

97153

98154Every node is `[%tag at=span …]`, so `+span-of` finds its span in one place; the few that aren't say so in the `%tree` chapter. The kinds of node:

99155

100156- **Module**: imports (`%sur` for `/-`, `%mark` for `/%`, `%jibb` for `/=`), then definitions (`%mold` for `+$`, `%value` for `++`).

101157- **Expressions** (`expr`): `%lit`, `%str`, `%path`, `%qath`, `%wing`, `%change`, `%pair`, `%unit`, `%group`, `%list`, `%tuple`, `%gate-wide`, `%ctor`, `%call`, `%gate`, `%cast`, `%trace`, `%branch`, `%crash`, and `%body` for an indented body, with its local definitions if it has any.

102−- **Molds as written** (`shape`): `%aura`, `%noun`, `%void`, `%flag`, `%const`, `%ref`, `%tvar`, `%path`, `%apply`, `%cell`, `%union`, `%fn`, `%generic`. A `%union` spans its first through last case and has no lead token; a single case is its own mold. `%generic` spans from the `|$` after a `+$` name through its body.

158+- **Molds as written** (`shape`): `%aura`, `%hole`, `%noun`, `%void`, `%flag`, `%const`, `%ref`, `%tvar`, `%path`, `%apply`, `%cell`, `%union`, `%fn`, `%generic`. A `%hole` retains the span of `_`; an inferred typed path segment retains that span separately from its enclosing segment. A `%union` spans its first through last case and has no lead token; a single case is its own mold. `%generic` spans from the `|$` after a `+$` name through its body.

103159- **Samples, fields and patterns**: a sample is `%bind`, `%face`, `%pun`, `%cell` or `%bare`, since a bare name binds anywhere in a sample; a pattern is `%lit`, `%str`, `%any`, `%bind` or `%cell`.

104160- **Literals** (`lit`) keep the form they matched, their aura and value, and their text as written, which the printers show.

105161

162+The parser accepts type holes. The partial checker records each ordinary hole with its span and validates the obligations created in a value or local definition before generalization. A solved concrete type or an explicitly written in-scope capital resolves a hole; a later use cannot repair it. Independent decimal holes may default to `@ud` when the surrounding inferred type is gate-free; variables reachable from the environment or written capitals are protected from premature defaulting. Structural named-mold holes are diagnosed at their source, while complex named molds, inferred path segments, recursive groups with holes and unresolved constraints remain unsupported. Partial prelude and API interfaces cannot silently export unchecked holes. A separate syntax-tree pass reports duplicate names within a written record at both field sites, including in unused definitions; nested and separate records have independent scopes.

163+

106164The tree keeps everything the checker needs to report an error at the code as written: open and closed brackets give the same node, but every node keeps its span.

Question 3 remains open; the field-order detail in question 32 is being clarified. The other questions are settled.

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.

@@ -37,13 +37,35 @@ Found while writing [prompts/milestone-2.md](prompts/milestone-2.md), checking i

373715. **Settled: unrestricted atoms and shared auras.** On 2026-10-30, @iko said `@` means any atom, independently at each occurrence, so Hoon `dime` and `pint` keep their bare-`@` fields. A specific atom such as `@ud` fits where `@` is expected; an `@` value needs a check to fit `@ud`. Shared atom types use one capital, with the atom constraint inferred from its body, as for `add` taking `[A A]` and returning `A`.

383816. **Settled: loobeans in union disjointness.** On 2026-10-30, @iko said `?` counts as its two atoms, `%.y` and `%.n`: it is disjoint from any cell and overlaps the constants 0 and 1.

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.

40−18. **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.

40+18. **Settled: the value gate `like`.** On 2026-10-31, @iko chose a gate `(like convert result)` that maps the product of an existing `(like A)` result with `convert=$-(A B)`, yielding `(like B)` while preserving its position and remaining input. An absent result stays absent. The `(like A)` mold remains available in the separate mold namespace. Hoon's wet `+like` instead builds a gate that constructs a result from an input noun; the chosen Jibb value gate is an adaptation of that behavior.

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.

424220. **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.

434321. **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.

444422. **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.

454523. **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.

4646

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. **Settled: how the prelude provides `ask` and `qath`.** On 2026-10-31, @iko chose ordinary transparent types defined in the internal prelude and re-exported normally, as for `poke`. Callers may construct and inspect their values.

50+

51+26. **Settled: the `step` example's `at` binder.** On 2026-10-31, @iko chose to rename the `describe` pattern binder to `sent-at`, keeping Hoon's `at` in the prelude and the no-shadowing rule.

52+

53+27. **Settled: duplicate fields in a Jibb-written record.** On 2026-10-31, @iko chose to reject duplicate field names, as for imported Hoon records.

54+

55+28. **Settled: arithmetic on loobeans.** On 2026-10-31, @iko chose to reject loobean operands for arithmetic. Comparison may still accept loobeans and returns `?`. The checker needs to retain this constraint through inference, generalization and instantiation before it exports `add` or `dec`.

56+

57+29. **Settled: printing the arithmetic atom constraint.** On 2026-10-31, @iko chose `where A is an atom other than ?` for a generic arithmetic type whose atom variable excludes loobeans.

58+

59+30. **Settled: a hole inferred as a generic variable.** On 2026-10-31, @iko said a hole resolved to an explicitly written type variable counts as inferred: in `++ id |= x=A ^- _ x`, the result hole is `A`. Named molds must determine their own holes without constraints from later uses; an unconstrained hole is an error.

60+

61+31. **Settled: uses of a value with a hole.** On 2026-10-31, @iko said a value definition must determine its own holes; another definition's use cannot fix an otherwise unresolved hole. For example, `++ id |= x=_ x` remains an error even if a later definition calls `id` with a cord.

62+

63+32. **Partly settled: type-directed record projection.** On 2026-10-31, @iko chose an explicit `(proj record)` whose expected result type selects the fields. There is no automatic projection, and `proj` is reserved against definitions and imports. The result contains exactly the fields of its expected type. Whether the result may reorder fields from the source remains open.

64+

65+33. **Settled: watching a request with unknown provenance.** On 2026-10-31, @iko said an island may watch a request only if the checker proves it watchable at compile time. An unknown request, including one built or passed through a gate without sufficient evidence, is rejected rather than deferred to a runtime check.

66+

67+34. **Settled: constructors and equal noun literals.** On 2026-10-31, @iko said expressions with the same runtime representation count as equal, and cases that cannot be distinguished at runtime are rejected at compile time. Thus `|=%$` matches a case headed by `%$`, `%.y` or `~`: each is the noun 0. Cases with equal heads and overlapping payloads cannot coexist in a union.

6161**Types and inference** (Grammar: Molds, Modules, Runes, Expressions; Decisions: Inference, Type variables, Sample names, Inline gates)

62−- Hindley–Milner with aura variables: "every expression has a principal type, and there is no general subtyping". A specific atom fits `@`, a specific noun fits `*`, and a more specific aura fits an ancestor in its Hoon aura family, each only in that direction; the reverse needs a check.

62+- Hindley–Milner with aura variables: "every expression has a principal type, and there is no general subtyping". A specific atom fits `@`, a specific noun fits `*`, and a more specific aura fits an ancestor in its Hoon aura family, each only in that direction; the reverse needs a check. Explicit `proj` is a type-directed operation.

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.

64+- The reserved, explicit `(proj record)` selects fields according to its expected result type. The checker records the projection and lowering evaluates the source once and builds that layout. A direct call does not insert a projection, and a module cannot define or import another `proj`.

6465- 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.

6566- Type variables are capitals, "generalized per `++`". A capital in a local `++` 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 takes a different capital. A body cannot force two distinct capitals to be equal; use the same capital where a type is shared. "A type variable used where an atom is required gains an atom constraint", so `++ clamp |= [lo=A hi=A n=A]`, calling `gth` and `max`, works on any one aura; "It can become nothing more specific: a body that makes `A` a `@ud` or a list is an error." Names "may refer to each other in any order", so infer `++` definitions in dependency order, a group of mutually recursive ones together.

6667- 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`.

6869- 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 ~)`.

6970- Generic molds: `+$ result |$ [V E]` with cases below, applied as `(result V E)`; `|$` goes right after a `+$`'s name, and the prelude's `cmd` and `sub` use `|$ [M]`.

7071- `!!` is the empty mold, and as an expression it has any type. `*` is the noun type, not a type variable; generic positions such as the keys in `each` and `table` use a capital. A value of a more specific noun type can be used where `*` is expected.

71−- `poke`, `ask` and `qath` are opaque, built only by derived gates, `pure` and application-path literals.

72+- `_` is an inferable hole wherever a mold can appear, including an inferred path-segment aura. A hole resolved to an explicitly named generic variable is resolved; an unconstrained hole is an error. A named mold or value definition must determine its own holes without constraints from later uses.

73+- `poke`, `ask` and `qath` are transparent types defined in the internal prelude and re-exported normally. Derived gates and `pure` also construct requests; application-path literals have type `qath`.

7274- The Literals table gives every other literal its type: `0x1f` a `@ux`, ships `@p`, dates `@da`, durations `@dr`, `~.knot` a `@ta`, strings `@t`, `` `x `` a `(unit A)`, `~[…]` a `(list A)`, `gap+%s2` the pair `[%gap %s2]`, `/posts/~zod` a `path`, `%/blog` a `qath`.

7375

7476**Tags, `~`, numbers and cells wait for their context** (Grammar: Tag resolution, Literals by context)

7577- A tag or `~` gets a fresh variable and a pending constraint, checked once unification fixes the variable: against a union's cases, by shape and shared tag positions, or as a constant atom for `@tas`, `@ta`, `@` or `*`. A literal that matches nothing is "an error naming the union, such as "msg has no case %submitt"".

76−- `|=%typed` is a case's constructor: "against `$-(@t M)` it is `|=(t [%typed t])`, requiring `M` to have a case `[%typed @t]`. It works for cases tagged at their head; a bare tag is always a value."

78+- `|=%typed` is a case's constructor: "against `$-(@t M)` it is `|=(t [%typed t])`, requiring `M` to have a case `[%typed @t]`. A literal case head matches by noun value, so `|=%$` also matches `%.y` and `~` heads; a bare tag is always a value."

7779- A variable constrained by tag resolution, and any it mentions, doesn't generalize; it stays open until something in the module fixes it. An island's `main` fixes its messages. A tag constraint still open when the module is checked is an error asking for a `^-`; the checker never guesses. Gate-free constraints are retained when generalized.

7880- "Wing access, changes and `?-` on a type not yet known wait the same way." A change with no items, `m()`, is an error; the parser still accepts it. Patterns don't wait: they're checked against the subject's type.

7981- Number and cell literals each "takes a default when its `++` is checked": a number `@ud`, a cell a tuple. But "A number takes `@ud` only if nothing fixes its aura and its `++` isn't generic over it", so `++ inc |= n=A (add n 1)` stays generic: unlike a tag's, a number's variable doesn't stop its `++` from generalizing. A cell can also become a record or, where a list is expected, a cons.

114116**The prelude** (overview: Prelude, Layout and styling, Links and URLs, Effects)

115117- Hoon's standard library regrouped, "written in Jibb and vendored as `/lib/jibb/prelude`", plus `eq`, `not`, `page`, `program`, `store`, `pure`, `island`, the layout elements and molds, `attr`, `theme`, and `cmd` and `sub` as the overview's Effects block writes them.

118120- 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.

119121- 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."

These one-way widenings are allowed: a value of a specific atom type fits `@`, a value of a specific noun type fits `*`, and a more specific aura fits an ancestor in its Hoon aura family; the reverse of each widening needs a check. Records can also be projected explicitly, as described below.

122122

123−- **Atoms**: `@` is any atom, regardless of aura; auras such as `@ud`, `@t`, `@p` and `@da` are specific atom types. An `@ud` value fits where `@` is expected, but an `@` value needs a check to fit `@ud`. A more specific aura also fits an ancestor in its Hoon aura family: `@ud` and `@ux` fit `@u`, and `@tD` fits `@t`. The reverse needs a check. Distinct specific auras remain distinct; sharing an ancestor does not make them unify. Each bare `@` independently accepts any atom: it is not an aura variable. Atoms that must share a type take one capital, as `[lo=A hi=A]`, with the atom constraint inferred from the body. `add` takes `[A A]` and returns `A`, with `A` constrained to atoms, so `(add n 1)` with `n=@ud` is a `@ud`. `?` is a loobean.

123+- **Partial annotations**: `_` may appear wherever a mold may appear. It marks a part of the type for the checker to infer, so a type annotation can specify only the parts it needs to. A hole inferred to be a named type variable is resolved: in `++ id |= x=A ^- _ x`, the result hole is `A`. An unconstrained hole is an error. A named mold or value definition must determine its own holes: `+$ box [item=_]` and `++ id |= x=_ x` do not determine their holes, and later uses cannot fix them.

124+- **Atoms**: `@` is any atom, regardless of aura; auras such as `@ud`, `@t`, `@p` and `@da` are specific atom types. An `@ud` value fits where `@` is expected, but an `@` value needs a check to fit `@ud`. A more specific aura also fits an ancestor in its Hoon aura family: `@ud` and `@ux` fit `@u`, and `@tD` fits `@t`. The reverse needs a check. Distinct specific auras remain distinct; sharing an ancestor does not make them unify. Each bare `@` independently accepts any atom: it is not an aura variable. Atoms that must share a type take one capital, as `[lo=A hi=A]`, with the atom constraint inferred from the body. `add` takes `[A A]` and returns `A`, with `A` constrained to atoms, so `(add n 1)` with `n=@ud` is a `@ud`. Arithmetic rejects loobean operands: `?` contains only 0 and 1, while an arithmetic result need not. Comparison may take loobeans and returns `?`.

124125- **Constants**: `%add`, `~` and the loobeans have one value each.

125−- **Records and tuples**: `[text=@t done=?]`, `[@t ?]`. An empty `[]` is an error. Faces are part of the type, so `[a=@ b=@]` and `[x=@ y=@]` don't unify. An unnamed position can unify with a faced position and take its face, so `[0 0]` fits `[x=@ud y=@ud]`; two different faces don't unify. A record too long for one line can leave its `[` open, with one field per deeper line, as an expression's bracket does.

126+- **Records and tuples**: `[text=@t done=?]`, `[@t ?]`. An empty `[]` is an error. Duplicate field names in a record are an error. Faces are part of the type, so `[a=@ b=@]` and `[x=@ y=@]` don't unify. An unnamed position can unify with a faced position and take its face, so `[0 0]` fits `[x=@ud y=@ud]`; two different faces don't unify. The explicit type-directed operation `(proj record)` selects fields from its argument according to the expected result type: `^- [x=@ud y=@ud] (proj wider)`, or `(f (proj wider))` when `f` expects that record. The source is evaluated once, and the result contains exactly the fields in the expected layout. No projection is inserted for a direct call. `proj` is reserved: a module cannot define or import another name `proj`. A record too long for one line can leave its `[` open, with one field per deeper line, as an expression's bracket does.

126127- **Unions**: a `+$` with several cases below it. Every union written in Jibb has a name, so one used in a field, a sample, a cast, a gate's mold or an argument gets its own `+$`; only imports bring in unions without one. 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.

127128- **Containers**: `(list A)`, `(unit A)`, `(set A)`, `(map K V)`, `(mop K V)`, `(qeu A)`, `(jar K V)`, `(jug K V)`.

128129- **Gates**: `$-(A B)`. Type variables are capitals, generalized per `++`. A capital in a local `++` shares the enclosing `++`'s variable of the same name if the enclosing `++` also uses it; otherwise the local `++` introduces and generalizes its own variable. For example, `++ inner |= y=A y` uses the enclosing `A` when its enclosing gate has a sample `x=A`; if the enclosing `++` does not use `A`, `inner` generalizes its own `A`. Use another capital for a different type. A body can't force two distinct capitals to be equal; use the same capital wherever a type must be shared. A type variable used where an atom is required gains an atom constraint, so `++ clamp |= [lo=A hi=A n=A]`, whose body calls `gth` and `max`, works on any one aura. It can become nothing more specific: a body that makes `A` a `@ud` or a list is an error.

129−- **Paths**: `/todos` is constant, `/` empty, and `/todo/[id=@ud]` typed by aura. `%/blog/(slug)` is an `qath`, checked against routes and static files.

130+- **Paths**: `/todos` is constant, `/` empty, and `/todo/[id=@ud]` typed by aura. A typed segment may use `_` for an inferred aura; it still must resolve to an aura that the path rules can print and parse. `%/blog/(slug)` is an `qath`, checked against routes and static files.

130131- **Generic molds**: `+$ result |$ [V E]` with cases below; `|$` goes only right after a `+$`'s name.

131132- **Noun**: `*`, not a type variable; use a capital for a generic type. A value already known to have a more specific noun type, such as `@ud`, can be used where `*` is expected. **Empty**: `!!`.

132−- **Opaque**: `poke`, `ask` and `qath`, built only by derived gates, `pure` and application-path literals. `(facts full diff …)` appears only in an API file's `paths`.

133+- **Pokes**: `poke` is defined in the source-backed private internal prelude module and re-exported by the public prelude as an ordinary transparent type. Ordinary modules can construct and inspect its values.

134+- **Effect and application-path types**: `poke`, `ask` and `qath` are transparent types, defined in the internal prelude and re-exported normally; callers can construct and inspect their values. Derived gates and `pure` also construct requests, and application-path literals have type `qath`. `(facts full diff …)` appears only in an API file's `paths`.

133135- **Identity**: recursive molds go by name and module.

134136

135−`eq`'s arguments and map and set keys must contain no gates, even nested inside another value. The checker infers this gate-free constraint on type variables and retains it when generalizing a `++`, so a generic helper that calls `eq` stays generic over gate-free types. Printed types show the constraint as `$-([A A] ?) where A contains no gates`. An inferred atom constraint prints as `$-([A A] A) where A is an atom`. Multiple clauses are comma-separated, as `where A is an atom, B contains no gates`. Union-case matching treats gates as opaque and never inspects a gate to distinguish cases.

137139## Tag resolution

138140

139141A tag literal or `~` gets a fresh type variable and a pending constraint: the variable must become a union with a matching case, or an atom type the term fits. A mold that isn't a union counts as a union of one case, for tags and for `|=%tag`: `[%go "x"]` fits `+$ go [%go url=@t]`, and `|=%typed` works against `$-(@t M)` when `M` is `[%typed text=@t]`. Once unification fixes the variable, each constraint is checked against the union's cases or, for `@tas`, `@ta`, `@` or `*`, makes the tag that constant atom. A literal that matches nothing is an error naming the union, such as "msg has no case %submitt".

140142

141143- A constraint records the literal's shape, such as `[@t %draft]`, and matches cases by shape and shared tag positions; a literal in a field position is checked against that field.

142−- `|=%typed` is a case's constructor: against `$-(@t M)` it is `|=(t [%typed t])`, requiring `M` to have a case `[%typed @t]`. It works for cases tagged at their head; a bare tag is always a value.

144+- `|=%typed` is a case's constructor: against `$-(@t M)` it is `|=(t [%typed t])`, requiring `M` to have a case `[%typed @t]`. It works for cases whose head is a literal with the same noun as the tag, regardless of how that literal is written: `|=%$` also constructs a case headed by `%.y` or `~`, since each is the noun 0. A bare tag is always a value.

143145- A variable constrained by tag resolution, and any it mentions, doesn't generalize; it stays open until something in the module fixes it. An island's `main` fixes its messages, so islands resolve their own tags. The inferred gate-free constraint is retained when a type variable is generalized.

144146- A constraint still open when its module is checked is an error asking for a `^-`; the checker never guesses. Library helpers can cast, as in `^- (list attr)`.

145147- Wing access, changes and `?-` on a type not yet known wait the same way.

The agent's mark rechecks on the ship; a nack's `tang` reaches the reply as text. Store constructors poke the store in the browser.

154156- A request such as `(todos.todo |=%got)` comes from a declared path or a store's `state`; its reply always gets full state. A path with diffs also takes a fold, `(changes.todo |=%got apply)`, which the runtime applies first. Facts are checked; a bad one crashes the reply, which counts as a crashed `update`.

155−- Islands read agents only by watching. A watch's first fact must be full state, so watching a request whose path case has a separate `scry=` path is a type error in an island. The runtime acks facts, rewatches after a kick or a dropped connection and reseeds from the first fact; a refused watch shows the crash notice.

157+- Islands read agents only by watching. A watch's first fact must be full state, so watching a request whose path case has a separate `scry=` path is a type error in an island. The checker must prove a request is watchable; unknown watchability is also a type error. The runtime acks facts, rewatches after a kick or a dropped connection and reseeds from the first fact; a refused watch shows the crash notice.

156158- Watches match by agent and path, timers by gap, and the newest reply is always used. After each `update`, `subs` is diffed to start and stop watches and timers. `%now` and `%every` give the time, `%who` the owner's `@p` from `/~/name`; `%wait` is a one-shot delay.

158160Inputs send a message per `input` event, and one per IME composition, so validation runs as you type; only commands reach the ship. After every event, controls reset to the latest view, so a toggle whose poke fails unchecks. A field's text is rewritten only when it differs, which keeps the caret. Fields are read-only until their island starts.

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 selected Hoon atoms, term singletons, 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, recursive molds whose origins can be verified through Ford imports, nested collections, direct ordered maps, certain ordered-map fields, direct `$^` unions whose cases can be proved disjoint, and one verified explicit union argument in a list, set, map or unit. Ambiguous recursive origins fail closed; recognizable explicit unions are checked from source before Hoon can collapse their cases, as @iko confirmed for imported `$%`, `$?` and `$^`, 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. 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, 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. Local mutual groups, polymorphic recursion, value cycles, 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. 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, some complex two-arm subjects and contextual union-pattern branches remain unsupported. The Grammar’s `step` block infers in this fragment, but its module is not yet checked. 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 zero nested inside a single tuple argument where a list is expected remains unsupported rather than a definite mismatch. 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. Uncontextualized list construction, 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; mutually recursive local groups and 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.

22+The parser accepts `_` in mold positions and typed path segments, retaining each hole’s span. The partial checker tracks ordinary annotation holes through inference and requires each value or local definition to resolve its own holes before generalization. A hole can resolve to a concrete type or an explicitly written in-scope type variable; later uses cannot fix an unresolved definition. Independent decimal holes can default, but captured variables are not defaulted prematurely. Structural named molds with an unresolved hole report its site. Complex mold forms, inferred path segments, mutual recursive groups and other unsupported constraints still fail closed, and the fragment does not claim the module is checked. A syntax-tree pass rejects duplicate field names within each written record and reports both sites. The repository spec now records that `ask` and `qath` are transparent; complete request checking remains outstanding.

2323

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.

24+On 2026-10-31, @iko chose explicit, result-directed `(proj record)` to construct a record with exactly the expected fields, and reserved `proj` against definitions and imports. The partial checker handles selected explicit calls with known, closed record types, records field-selection evidence for later lowering, and reserves the name across source bindings. Reordered fields, some nested contexts and several open or recursive cases remain unsupported; lowering and execution are not implemented yet. The field-order question remains open.

25+

26+The internal prelude also defines `qath` as a transparent recursive knot sequence, re-exported by the public prelude. The partial checker recognizes its source identity, supports selected null/cell construction and matching, and types static application-path literals. Construction and matching for other recursive shapes, broader patterns and dynamic application-path segments remain unsupported. A 256-step limit applies per inference attempt, not to parsing or retries; checking routes and static files remains milestone 4.

27+

28+The checker also recognizes a limited source-proven generic recursive tree in an import-free defining module. Its nominal identity retains the defining path, mold name and type arguments, including across supported imports and aliases. With a known expected type it can construct supported tagged cases by checking one source-proven layer at a time. Flat matches with two explicit tags also work for these source-proven trees, as does a missing-case diagnostic for a supported single-arm match. Broader pattern matching, general structural fits and gate-free proof remain unsupported; this is not yet the prelude's `element` implementation or island checking. The source index uses fixed-shape checks during mold collection. Each construction or supported pattern attempt has 256 unfolding steps and at most 4,096 face and substitution visits per scan; pattern subject recognition and view validation can each scan separately. Parsing, other inference and retries remain outside those limits. A single startup-inclusive comparison of 1,000 ordinary gates produced identical reports and used 29.12 seconds of user CPU before the shared-resolver refactor and 28.55 seconds after it, with other work running; it is not a general performance bound.

29+

30+The internal prelude defines a transparent generic `ask` with pure, agent and store cases, re-exported alongside the Jibb-written `pure` gate. The partial checker infers supported constructors and exhaustive matches. Agent and store receivers operate on raw nouns; their fields do not prove schema validity or watchability. The public prelude now defines the documented source-backed `sub` union; supported `%watch` payloads retain the public `(ask M)` type. Constructing a `sub` does not prove that its request is watchable. Request lowering, checked decoding, runtime validation and island watch checking remain unimplemented.

31+

32+Known same-origin generic-union result context can now constrain a call before its arguments are inferred. An unresolved or opaque constructor target stays unsupported rather than producing a definite mismatch; proven missing tags still report errors. A todo request with explicit `(ask msg)` context can infer `|=%got`; its uncontextualized form remains unsupported. A two-item literal-headed tuple can receive payload context from a known union of uniquely headed literal cells when its payload is a shallow wing-headed call with literal, wing or constructor arguments. Existing inference takes precedence when it fits; otherwise the checker tries the contextual path once. It conservatively declines that path when any substitution has a structural root, as well as for duplicate or opaque competitors. The guard scans substitutions per eligible tuple and may add one shallow inference; no global linear-time bound is claimed. This allows an explicitly typed todo subscription body to infer, but does not check the island or prove request watchability.

33+

34+A separate source-backed analysis can prove one named mold gate-free, report a definite gate with a field path, or return unknown. It retains the prepared prelude, source bundle, reader results and resolved imports; the actual todo model proves gate-free, while a callback field reports its path and `*` remains unknown. Its classifier is capped at 256 nodes, not the surrounding parse and import work. API, store and private roots are unsupported, and the artifact does not check a module or island, infer generalized constraints, or prove watchability.

35+

36+The partial checker can also match a directly named, checked root gate against a generic gate sample in a direct, unshadowed source-backed prelude call. It uses the written two-slot sample layouts to preserve nested record faces, then requires the complete call samples to be closed and tag-free and repeats the fit under the final substitution. The proof falls back to existing inference for unavailable or ambiguous source layouts, local or dynamic gates, aliases, recursive placeholders and open generic caller types. It preserves written-capital checks and projection evidence; it does not add `program`, check islands or prove request watchability. Prepared prelude source and interface remain a trusted pair.

37+

38+The API path analyzer can retain its source, complete prepared prelude, reader results and resolved dependencies as evidence, and classify a unique declaration as watchable, not watchable or unknown. It does not yet prove the provenance of request values or check island subscriptions. Prepared artifacts and reader results remain trusted host inputs.

39+

40+For a unique supported path declaration, the request-parts analysis derives ordered typed path parameters, a full-state reply sample and a fold type for one diff mark. Multiple diffs and unsupported or ambiguous evidence fail closed. By itself it does not create request gates or establish watchability of values.

41+

42+A separate supporting-definition analysis infers supported ordinary API molds and values and resolves all declared marks, retaining their source and dependency evidence. It fails closed on unsupported helpers or marks; unused `/-` cores are not independently validated, and definitions depending on derived gates remain unsupported. This does not check or export the whole API.

43+

44+Ordinary imports can infer derived request-gate types for multiple supported API paths. A case may take one typed segment before the reply or one diff fold after it; the unchanged todo API's plain, typed and diff requests infer, including a named closed fold. Checked ordinary API definitions, mark molds and a supported poke constructor are exported. Each `/sur` core must have a directly used, successfully read mold; unselected bindings are not independently validated. Jibb module imports, scry paths, multiple parameters or diffs and a parameter together with a fold remain unsupported. Source-qualified request evidence and exact trusted graph inputs survive transitive imports and cached interfaces, while stale or ambiguous evidence fails closed. This is a type-only interface: request execution, schema validation and proof that a request value is watchable remain unimplemented. In one loaded-machine run, the real-todo eval took 195.83 s wall and 67.83 s user CPU; the prior prototype took 111.81 s wall and 64.60 s user. Both include Hoon compilation and reader setup and overlapped other work, so they are not isolated checker benchmarks.

45+

46+The Hoon reader's tagged-union source proof also handles `$~` default wrappers. A shared eval and ship golden exercises the unmodified Tlon `epic.saga` mold as a named payload in a labeled downstream extension, alongside overlap, recursive, shadow and malformed-wrapper controls. The tagged-source helper peels at most four consecutive defaults; defaults inside dependency proofs spend the existing semantic-node budget. Other unverified nested unions and dependencies remain unsupported.

47+

48+The repository spec records the subsequent type-system and prelude decisions, including the chosen `like` result-mapping gate; 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, including Tlon `notes.import-node` with list-wrapped self references, 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, including source-validated named operands such as Tlon `notes.log`, 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, bare `~` fields and one level of local named tagged unions, as in real Tlon `notes`, with 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 `$^`, while other nested unions, nested ordered maps, general union disjointness and complete import integration remain unfinished. Opt-in structured reader APIs preserve successful graphs and distinguish definite unsupported-aura and core evidence from failures the reader cannot prove; unverified union disjointness and name-only vase recognition remain unsupported. They revalidate and re-walk failed types. An opt-in partial checker entry point consumes unchanged reader results and reports definite aura or core errors at imported mold use sites when their inputs are unique. Ordered replay covers nested cell samples, record and function casts, and non-generic same-module aliases; unsupported prefixes, cycles and shadowing stop it. Union molds, generic applications, transitive modules and unsupported reader outcomes remain generic. Replay repeats inference and may add work. The partial checker resolves a subset of ordinary library imports in dependency order using supplied Jibb sources and a source-derived partial prelude interface, caches completed interfaces per run, detects missing sources and cycles, and resolves nested fields of imported values with independent scheme instantiation. The source-backed internal prelude defines `poke` and the public prelude re-exports it as a transparent type. A dedicated trusted preparation path supplies private comparison and arithmetic schemes to the Jibb-written `gth`, `add` and `dec` wrappers; ordinary imports cannot access them. The public `add` and `dec` wrappers use private arithmetic interfaces; supported inference preserves the shared atom constraint that excludes loobeans. Primitive execution, jet recognition and length remain unfinished. The partial checker resolves its supported source shape and rejects ordinary imports of the private path. An imported API with one mark and a matching direct `+$ 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 by itself create requests or check an API module. Ordinary imports additionally infer the supported multi-path request-gate types described above. Complete private module checking, other API shapes, request lowering, root API and kind checking, stores, complete `ask` and `pure` checking 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 includes the doc-exact generic `cmd` union; 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. Known loobean result context also propagates through supported complete branches and binder-only cell arms; binder-only arms over union subjects remain unsupported. A directly known named union can instantiate an unconstrained generic gate sample with its origin, generic arguments and faces preserved; unnamed, pending, recursive and variable-bound cases remain unsupported. A known gate with an unresolved result variable can receive a known enclosing result type before its arguments are inferred; unknown calls and unresolved targets remain conservative. 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. A structured single-arm pattern also works for a known non-union cell when coverage is proven, including nested literal and wildcard positions. 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, a grouped wing or a supported shallow call, including nested cell and list positions; other partial-pattern contexts and subject forms 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. Literal singleton heads compare by runtime noun, so `|=%$` also matches explicit null- and loobean-zero-headed cases. When equal heads have disjoint payloads, the constructor selects a uniquely proven compatible payload; unknown and ambiguous candidates remain unsupported. 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 agreed shared-type `clap`; supported calls infer, while backend validation remains outstanding, and [prelude-inventory.md](prelude-inventory.md) is a source audit, not the complete inventory or signatures. The milestone remains unfinished.

50+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`, `bond`, `lure`, `weld`, `snoc`, `turn` and `lent`. 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. The same validated template is available when prelude mold aliases are prepared, so supported direct and transitive aliases can use it. 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. The source-only `+prepare-prelude` rejects empty, malformed, conflicting or import-bearing source; `+prepare-prelude-with-internal` also accepts the supported private internal import. Prepared values are trusted and must come unchanged from the matching preparation arm. When canonical public list or unit templates are missing or altered, independently inferred private molds remain available, while molds that depend on those templates do not. 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.

51+

52+The prelude also has a Jibb-written `zing` that concatenates homogeneous lists via `weld`. Its focused golden infers empty, nested text, ship, generic and gate-element lists and reports a non-list error; the same golden passes on the ship. A Hoon translation agrees with Hoon `zing` on selected finite inputs, not on Jibb execution. Hoon’s raw helper additionally accepts heterogeneous noun lists, which the Jibb signature does not express. Backend lowering and jet recognition remain unverified.

53+

54+An eval and ship fixture now reports partial inference for the unchanged todo island with its real API and Hoon readers. It verifies that the source fixtures match `my-app` and exercises missing or duplicate imports; the report does not claim the module or island has been checked. The prelude also has a Jibb-written recursive `lent` whose supported generic calls infer `@ud`. Execution and shape-based jet recognition remain future backend work. Nested union tests check equal runtime nouns, different nested tags, empty fields and unknown inhabitation.

55+

56+The prelude now writes `lth`, `gte` and `lte` in Jibb using `gth` and `not`. Supported generic and concrete calls infer, including loobeans; mismatched explicit auras fail. Execution, jet recognition and complete import checking remain unfinished.

57+

58+The Hoon reader can prove overlaps among supported original `$?` source cases, including nested cells and unions with more than two cases, and report them at a Jibb use site. It evaluates each case independently and compares runtime noun values. Other overlaps, Hoon case locations and mark-reader overlap diagnostics remain unfinished. The source screen allows at most 128 cases and 4,096 source noun nodes; dependency checking and pairwise witness analysis each have a separate 4,096-node budget. These budgets do not bound chapter lookup, Hoon evaluation or graph walks.

59+

60+Restricted-number promotion now skips an environment scan when a definition has no written capitals. In a single startup-inclusive pair on 2,000 independent gates, output was identical and user CPU fell from 71.67 to 38.26 seconds; wall time was 72.80 versus 51.66 seconds with other checks running. This is a partial-inference measurement, not a complete checker or a bound on dependent modules.

Desk sync took 80.9 s while other checks were running. The importer golden compares 221 projections; `tools/clay-fixtures` builds the example Hoon fixtures through Clay, checks a recursive Ford import's origin, and passes Clay-built types through the Clay-built importer and partial checker.

80+- `tools/testdata/selftest` (22 checks), `tools/testdata/ship-selftest` and `tools/testdata/clay-fixtures-selftest` test the tools themselves; the last checks temporary Clay fixture cleanup and signal handling without a ship.

4581- 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.

4682- 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).

11source: Overview, Prelude: "The exported inventory includes all names from the Hoon library sections listed below, excluding the groups explicitly left out"; Hoon 2a includes `drop`, `bind`, `biff`, `flit`, `both`, `clap` and `clef`, and 2b includes `join`, `murn`, `rear`, `snip`, `skim`, `skip`, `levy`, `lien`, `roll` and `reel`. Folds take an explicit start.

2−tests: The complete current prelude parses, including unit-to-list conversion, unit mapping and flat mapping, a curried unit-producing filter, three ways to combine units, including `clap` with one shared value type, complementary list filters, present-product mapping, joining, last-item operations, all/any predicates, and left and right folds. The filters retain the order of their selected items.

1+source: Grammar, literals by context and type variables: calls can receive expected result types while preserving shared type variables and pending constraints.

2+tests: A known identity-like gate receives list, null, unit, union and nested record contexts. Incorrect items, tags, auras and repeated arguments report errors; unrelated pending literals and explicit capital restrictions remain. Generic list and union results instantiate independently, captured variables retain their scope, and unsupported recursive inference fails closed. The module report remains partial.
