…ce pass createBinder walks the symbol table once at creation, registers every declaration node against its symbol, and resolves each field's type reference through the decreed chain: declaring namespace, then top level, then the universe scope built from the injected type-constructor registry. Sibling namespaces are never consulted, user declarations shadow universe symbols silently, cross-space references get an explicit kind with no diagnostic, and malformed types are skipped. Unresolved references are reported under the new PSL_UNRESOLVED_REFERENCE code, returned beside the binder. The universe scope is memoized per registry object so it survives document edits. Attribute-reference resolution is not part of this pass. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Signed-off-by: Steven McClankerton <tatarintsev@prisma.io>

…the binder Phase 2 runs after phase 1 in the same eager pass and reads its results. Each model, composite type, and field attribute is matched against the injected attribute-spec registry: a hit records the spec against the attribute's name node, a miss reports PSL_UNRESOLVED_ATTRIBUTE. Arguments the spec declares as references are then resolved by kind - fieldRef against the declaring owner's fields, referencedFieldRef against the phase-1 type target via a map read (cross-space field types yield the explicit kind with no diagnostic), and entityRef through the namespace-then-top-level chain, where universe symbols and blocks are not entities. The registry is a structural view of the spec's argument shapes, so the binder reads the combinator kinds without depending on any target package.

…aring field A referencedFieldRef argument outside a field attribute has no field whose type could name the target, so the binder now records nothing and reports nothing rather than falling back to the declaring owner's own fields. Pins the two silent branches: this one, and a non-identifier expression in a reference slot.

Exports createBinder, the Binder interface, the resolution union, the two diagnostic codes, and the universe types from the package entry, so consumers can resolve names without reaching into src/. Adds the attribute-context helper the conversion slices need: modelAttributeContext and fieldAttributeContext build the ADR 249 parse-time contexts from a binder, with resolveReferencedModel served by one map read narrowed to a model. The attribute-spec machinery is untouched - the helper adapts to it. The README now documents the binder: the scope chain, the resolution kinds, who owns resolution diagnostics, the snapshot lifetime, how universe-scope sharing depends on registry object identity, and the red-node identity guarantee that makes the side tables sound.

…'s voice The parse-time AttributeCtx now carries the binder, and the D4 context builders populate it. When it is present, fieldRef, referencedFieldRef and entityRef read the argument's resolution out of the binder - a map read of results computed at creation, keyed by the very node the combinator holds - and raise no existence diagnostic of their own. An unknown name is reported once, by the binder. Without a binder on the context the combinators behave exactly as before, so unconverted call sites are untouched; the existing attribute-spec suite pins that and is unmodified. Shape and arity failures remain the combinator's voice in both modes - only existence moved.

The reference combinators defer to the binder whenever one is on the context, not only when the lookup hits, so a binder from another snapshot or from registries disagreeing with the interpreted specs drops existence diagnostics without a word from either voice. Say so where the wiring is documented. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Signed-off-by: Steven McClankerton <tatarintsev@prisma.io>

…nce arguments AttributeCtx no longer carries resolveReferencedModel, and ModelAttributeCtx requires a binder, so every context that can reach a reference combinator has one by construction - there is no second path to fall back to. fieldRef and referencedFieldRef resolve solely through the binder: a bound field yields its name, a cross-space reference parses as before, and anything else fails the argument while staying silent, because the binder has already reported that name. entityRef keeps its success semantics and its base-level context, since block attributes are interpreted before a binder can exist. Failing an argument without a diagnostic needed the aggregation points to stop inferring failure from diagnostic count: list, record and interpretArgs now track it directly, so a silent failure fails its attribute rather than quietly yielding a short list or a missing key. Binder diagnostics carry the class of reference that failed, letting a consumer adopt the binder's voice for the questions it has converted and keep its own for the rest. The attribute-spec registry now sees the declaring owner, so a spec a consumer builds per model is visible to the binder rather than looking unknown.

…esolution Both interpreters now construct a binder once from the snapshot artifacts they already hold and thread it into every attribute context, so the reference combinators resolve through it. Their binder diagnostics are pushed into the interpreter's collector rather than discarded - without that, removing the combinators' existence checks would have left unknown names unreported and contracts quietly missing constraints. Each universe is built from what its target actually recognises: SQL folds in the composed scalar descriptors and the field presets that are legal in type position, Mongo its scalar codec map. Both registries answer permissively for attribute names they do not own, because each interpreter already voices its own unsupported-attribute diagnostics and a second complaint would duplicate them. Mongo keeps PSL_UNSUPPORTED_FIELD_TYPE as the authority on type names it recognises but cannot store, so it takes the binder's other reference classes and leaves that one alone. Two corrections follow, both intended: an unqualified reference no longer finds a model in a sibling namespace, and it now says so instead of dropping the relation; and the interpreter's own missing-@@base-target diagnostic gives way to the binder's.

Mongo adopted the binder's reference classes without giving up the emissions they replace, so a missing @@base target drew two complaints. Its PSL_BASE_TARGET_NOT_FOUND now goes the way SQL's did, leaving the binder's entity voice alone. An unknown @@index field drew two as well, by a route the earlier survey had judged unreachable: Mongo builds its index element as oneOf(fieldRef(), ...) through a separately assembled arm list. A reference argument that fails silently inside oneOf now propagates that silence instead of drawing "Expected one of" over it, while an alternative that fails loudly still speaks and a later alternative can still match what an earlier one refused. The affected assertions used containment, which passes when an extra diagnostic appears; the new tests pin the exact code list per schema, and record which second codes are consequences of a failure rather than second opinions about it.

Reaching for one child allocated a wrapper for every sibling beside it, so walking to a single field in a wide document built the whole row. Each slot is now filled on the access that needs it, with child offsets accumulated as far as they have been asked for, so repeated access stays a lookup and a full walk still costs one pass.

A qualified type whose extension pack is not composed drew two complaints: the binder could not resolve pgvector.Vector, and the interpreter said the pgvector pack is missing and named the config key to add. Both describe the same fault and only one tells the author what to do, so the interpreter now drops the binder's reading of a name it is about to report itself. The binder's unresolved-type diagnostics carry the name that failed, so a consumer can recognise the question without reading the prose.

The same boolean appeared at four aggregation points and was named after what happened rather than why it mattered. A child that fails carrying no diagnostics has been reported by another voice already - the binder - so the aggregate must fail without adding a complaint of its own. list, record and interpretArgs set the flag on any failure, which was redundant: a child that fails loudly pushes its diagnostics into the same array, so the count test already caught it. Narrowing each to the silent case makes the name true and leaves behaviour identical, and all four now read as one mechanism through a shared alreadyVoicedElsewhere. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Signed-off-by: Steven McClankerton <tatarintsev@prisma.io>
The binder left the side table silent for a reference it could not resolve, so an absent entry meant either a schema mistake or a binder built over a different tree, and the combinators could not tell the two apart - the second case quietly skipped existence checking for the whole document. The binder now records an explicit unresolved entry for every reference it examines, including the referenced-field case that has no declaring field. An absent entry therefore has only one meaning left, and the reference combinators raise an internal error naming the same-snapshot precondition rather than proceeding. Resolution outcomes are unchanged: unresolved still parses to a wordless failure, cross-space and bound fields as before, and no diagnostic moved. A malformed type stays unexamined, which stays safe because no combinator ever reads a type node.

Three aggregation points each carried a boolean recording that some child had failed wordlessly, because failure could not survive being flattened into a diagnostics array. Result gains `and`: ok only when both sides are ok, and two failures keep both sides' diagnostics in order. Folding with it carries failure through the accumulation itself, so list, record and interpretArgs drop their flags and read their verdict off the fold. parseArgValue no longer writes into a caller's array on the side; it returns its result and interpretArgs folds it, which is what let the accumulator become the single account of what went wrong. oneOf keeps its own rule: it pools alternatives rather than conjoining them, so folding would surface every alternative's complaint in place of its summary and would lose the wordless propagation - the emptiness check it still needs now lives beside it.

We should not need this, we introduced and specifically to remove this
The emptiness test had a name again, which was the objection: `and` was introduced to carry failure through accumulation, and oneOf was still asking about it by hand. Result gains `or`: the first ok wins with its value, and two failures combine on the failure lane where a detail-less failure is absorbing - a rejection already reported elsewhere outranks the alternatives' complaints rather than being buried under them. oneOf folds its rejections with it, so the wordless case arrives at the tail as a property of the fold. Alternatives are still tried in order and the first match returns immediately; evaluating the rest would now be able to throw, since a reference combinator treats an unexamined node as a snapshot mismatch. The summary is unchanged: it is built from the alternatives' labels, never from their diagnostics.

Can you get rid of all undefined checks and itialize accumulator with notOk([])?
"Universe" borrowed a term from language specifications for a scope that holds no language built-ins: its names are whatever the configured target and its composed extension packs contribute in type position - scalars, type constructors, field presets. The scope, its symbol, its resolution kind and the docs now say contributed types instead, matching how the repo already names target-contributed surfaces elsewhere. Rename only; every assertion is untouched and the test titles moved with the vocabulary.

They were introduced with the two combinators in this branch, and the second insertion left the conjunction paragraph standing above `or` while `and` went bare. The laws are pinned by tests rather than described in prose. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Signed-off-by: Steven McClankerton <tatarintsev@prisma.io>
The accumulator started empty and every step asked whether it existed yet. Alternatives are already typed as a non-empty tuple, so the first arm is the seed and the rest fold onto it - the undefined checks are gone without touching the fold's law. Seeding with notOk([]) would have been the shorter spelling and the wrong one: a detail-less failure is absorbing on the disjunction lane, so it would make every fold wordless and leave the "Expected one of" summary unreachable.

Both combinators arrived with their only coverage coming from the parser that uses them. These cover each lane directly, including the one that is easy to reach for and wrong: on the disjunction lane a detail-less failure absorbs the other side, so it can never serve as the fold's seed.

…espaces The binder described the spec shapes it needed with its own interface, so every consumer wrote an adapter translating tables it already had into a mirror of them. It now takes the namespaces themselves, plus the one ingredient the factories need that it could not already supply, and calls each factory with the ADR 249 context built from the owner it is walking. An attribute name resolves to an attribute symbol rather than a bare spec, so it reads like every other name the binder answers for, with the spec reachable through it. A name absent from the namespace is left to its target, which is what both registries already did by answering permissively - so the weak unresolved-attribute diagnostic and its reference class go, having never reached a consumer.

Both packages kept an adapter that reshaped their spec tables into the binder's view and answered permissively for names they did not own. The binder takes the tables now, so the adapters go - and with them the two keyof casts the SQL and Mongo lookups needed.

… callback The binder already knows which attribute names the bound spec namespace registers; until now it skipped an unregistered name in silence and left every target to rediscover the same fact with its own scan. createBinder now takes an optional describeUnsupportedAttribute, called once per unregistered name with the attribute, its level, its owner and (at field level) the field. A returned diagnostic joins the binder own diagnostics; undefined, or an omitted callback, keeps the silence. Signed-off-by: Steven McClankerton <tatarintsev@prisma.io>
…lback SQL and Mongo each walked every attribute a second time to rediscover the names their own spec namespace does not register. Both scans are gone; each family now hands the binder a describeUnsupportedAttribute that phrases the same verdicts. SQL keeps its four-branch cascade intact - contributed model attributes stay silent, db.* attributes get the migration prose, an uncomposed extension namespace gets PSL_EXTENSION_NAMESPACE_NOT_COMPOSED, and the rest get the base message plus any removed-attribute hint. Codes and wording are unchanged at both levels, and reportUncomposedNamespace now delegates to uncomposedNamespaceDiagnostic so the prose has one home.

There was a problem hiding this comment.
wtf, why did you change it from simple loop to internal function?
Owner is a relation - the owner OF a field, of an attribute - and the binder uses it correctly in BindContext, resolveOwnerField and the unsupported-attribute callback. It was also doing second duty as a category noun for the models-and-composite-types union, which is the set entityRef already resolves and the set AuthoringContributions calls entityTypes. The category positions take that word: interface Owner becomes ScopedEntity with an entity field, and the owners() generator becomes entities(). Every relational owner stays as it was, the callback surface included, so no consumer moves. Signed-off-by: Steven McClankerton <tatarintsev@prisma.io>

Only the namespace records were prototype-less; the top-level models, composite types, named types and blocks, and every fields record, were plain literals. A schema declaring nothing named toString still answered topLevel.models["toString"] with Object.prototype.toString, and every consumer that indexes these records unguarded - SQL, the language server - inherited that answer. buildSymbolTable now produces Object.create(null) for all of them, so plain indexing under noUncheckedIndexedAccess returns undefined for a name nobody declared. The binder reads the records directly and keeps own() only where the record comes from a consumer literal whose prototype is still attached: the attribute-spec namespace and a spec own named parameters.

A spec stored its author literal straight through, so looking an argument name up on it answered @relation(toString: ...) with Object.prototype.toString. The record is now copied onto a null-proto object at assembly, which is where the guarantee belongs; the binder reads it by plain indexing. Signed-off-by: Steven McClankerton <tatarintsev@prisma.io>
…hain The binder had two resolution cascades: type references walked models, composite types, named types and blocks, while entity references walked only models and composite types. A namespaced enum therefore shadowed a top-level model for a field type but not for @@base, which saw past it to the outer model - two scoping rules for one language. Namespace, top-level and contributed-type scopes now share one shape, lookup(name), and resolution is a fold over the chain with first hit winning; a qualified reference builds the shorter chain rather than taking a separate branch. Within a scope a name denotes at most one symbol, which the table guarantees by claiming model, composite type, block, named type and namespace names from one set per scope, so the order inside a scope carries no meaning. What a reference site requires is checked after resolution. An entity reference that lands on an enum, a scalar or a namespace now says what the name is instead of claiming it cannot be found, and the top-level scope answers for its namespaces so a type reference naming one says so too.

Summary
Add a binder to
@internal/psl-parser:createBinder({ sources, symbolTable, typeConstructors, attributeSpecs })returns{ binder, diagnostics }, resolving every type reference and attribute reference eagerly per snapshot and answering node-addressed queries —declaredSymbol(node)for declarations andsymbolForNode(node)for references. This is the groundwork for retiring the four hand-rolled resolvers (SQL interpreter, Mongo interpreter, language server, attribute-spec callbacks), which today disagree on namespace scoping; they convert in follow-up PRs.Changes
syntax/red.tscaches child wrappers in parent slots, so repeated traversal to the same position returns the identical object andWeakMap-keyed side tables are correct.SyntaxNode.childAtbecomes a public navigator. The green layer is untouched.binder.ts): one eager two-phase pass over the symbol table. Phase 1 registers declarations and resolves field type references through the scope chain — declaring namespace → top level → universe scope, sibling namespaces never consulted. Phase 2 resolves attribute names against an injected spec-registry view and reference-kinded arguments (fieldRef,referencedFieldRef,entityRef), reading phase-1 results for@relation(references:)targets. Resolution kinds includeblock(enums) and an explicitcrossSpacekind (no diagnostic) replacing today's silent skip.universe-scope.ts): scalars/type constructors as symbols in a config-derived outer scope, shared across snapshots by registry object identity; user declarations shadow universe symbols silently.PSL_UNRESOLVED_REFERENCE/PSL_UNRESOLVED_ATTRIBUTEcodes with filename + range viaPslSources, returned beside the binder in thebuildSymbolTableresult shape.binder-context.ts):modelAttributeContext/fieldAttributeContext/referencedModelbuild the attribute-spec parse-time contexts withresolveReferencedModelas a binder map read, mirroring the SQL interpreter's private builders so conversion slices delete their local copies.resolveReferencedModelis deleted along with all four consumer-supplied implementations);fieldRef/referencedFieldRefconsume the binder's resolutions and fail the parse on a non-field, emitting no diagnostics of their own; the parse machinery (list/record/ arg aggregation /oneOf) learned to distinguish failure from diagnostic count so a silent failure propagates instead of truncating values. Binder diagnostics carry the class of reference that failed (type/field/entity/attribute), and each consumer adopts the binder's voice class by class.PSL_UNSUPPORTED_FIELD_TYPEas thetype-position voice) and pushes the binder's diagnostics into its collector; duplicate resolution-class emissions (PSL_BASE_TARGET_NOT_FOUNDin both interpreters) are removed, pinned by exact-set diagnostic assertions. The language server constructs no attribute contexts and is untouched.PSL_UNRESOLVED_REFERENCEper the decreed scope chain (declaring namespace → top level → universe; sibling namespaces are never consulted). Qualify the reference (auth.User) to keep such relations. This corrects a documented resolver defect and belongs in release notes.exports/index.ts; README gains a## Bindersection (scope chain, resolution kinds, diagnostics ownership, snapshot lifetime, node identity).projects/symbol-table-resolve/: project spec, plans, design-decision record, and trace for this project (transient project artifacts).Why
Four consumers answer "which declaration does this name denote" independently and differently — the SQL interpreter checks top level then sibling namespaces in arbitrary key order, the LSP prefers the declaring namespace, Mongo ignores namespaces. The binder canonizes lexical scoping and single-voice diagnostics behind one API, designed after surveying Roslyn, TypeScript, rust-analyzer, and clangd; the reasoning and rejected alternatives are recorded in
projects/symbol-table-resolve/design-decisions.md.Scope
The parser gains the binder; SQL and Mongo interpreters gain attribute-resolution through it (their remaining hand-rolled type-reference/relation machinery converts in follow-up PRs); the language server and
