Most are: -1. **Name-based membership checks** — `n.name == "Callable"`, `is_container_type(name:)`, magic name allowlists -2. **Fail-open fabrication** — `None => unit_type`, `None => ""`, `None => false` -3. **Field-presence assertions** — `body != none`, `transport != none`, `params |> count > 0` - -**Modeling implication:** Field-presence assertions (category 3) are -already correct — `body != none` IS the structural fact. The problem -is that consumers can't reach these fields at the boundary (they're -stripped or re-keyed by side-tables). The fix is making existing fields -(`body`, `transport`, `connective`) reachable at every consumption -site, not adding derived `has_reduction?` wrappers (that would -duplicate the existing authority). Name-based checks (category 1) -dissolve when consumers read the structural fact the name approximates -(e.g., algebra profile instead of `"List"` string). Fail-open sites -(category 2) need fail-closed boundaries, not ontological modeling. - -### Algebra sites (~27) — "how does this compose?" - -Almost all are connective dispatch: -1. **Conj/Disj/NoConnective branching** — field access path, type summary, type equality -2. **Container arity** — `children |> count == 1` vs `== 2` for element vs keyed collections -3. **Container-to-algebra mapping** — hardcoded string tables (coercion.dag) - -**Modeling implication:** Connective IS the existing authority. -Consumers that re-derive "product or coproduct?" should read -connective directly (or its existing downstream authority, -`TypeSummary.repr`). Adding a new TypeShape enum would duplicate -connective — the fix is surfacing connective/TypeSummary.repr -through stage boundaries. Container arity (2) should come from the -existing algebra profile (which already carries parameter counts). -The hardcoded container-to-algebra table (3) is already identified -as needing derivation from algebra declarations. - -### Reduction sites (~44) — "what happens?" - -Three clusters: -1. **Method/function name dispatch** — 13-way algebra method dispatch, builtin registry, "fold" special-casing -2. **Call/application classification** — call tier, nullary detection, binding kind -3. **Target language dispatch** — per-backend rendering, keyword/primitive coercion - -**Modeling implication:** The `method_def` Node and `AlgebraFieldTemplate` -already carry method identity structurally. Method name dispatch -(category 1) dissolves when consumers read from these existing -authorities instead of matching on name strings — not by adding a -parallel AlgebraMethodKind enum (duplicate representation). The "fold" -special cases in ownership.dag dissolve when ownership reads the -existing algebra framework's structural facts about fold. Call -classification (2) dissolves when inference normalizes ExprVar→ExprCall -for nullary functions (making the expression IR the authority). Target -dispatch (3) is inherent — different targets need different rendering — -but fail-open fallbacks (fabricated error markers) should be -fail-closed. - ---- - -## Per-file detail - -### 00_core.dag - -| Lines | Heuristic | Cat | Question | With ontology | -|-------|-----------|-----|----------|---------------| -| 1038-1041 | `t.name == "rest"` / `"shell"` / `"file"` / `"local"` | R | What transport kind? | Transport kind = ReductionKind (external variant).

When data is missing, the site -fabricates a default (unit_type, empty string, false) instead of -producing a diagnostic. This allows ungrounded claims to propagate. - -**Ontological fix:** Fail-open is not solved by the Signal/Algebra/ -Reduction ontology directly. It requires fail-closed boundaries: -every lookup returns `Result`, never `T` with a -silent default. The ontology helps indirectly: with structural -decomposition, there are fewer "what kind?" questions to ask, -so fewer opportunities for miss → fabrication. - -### Pattern 2: Re-derived classification (~25 sites across MM-1) - -Four independent forests classify Nodes into item kinds. Each -inspects the same fields with subtly different priority. - -**Ontological fix:** Direct dissolution. Node decomposition into -Signal/Algebra/Reduction makes classification a pattern match: -`{connective: NoConnective, body: present, transport: absent}` → FnItem. -Computed once, carried structurally. The four forests merge. - -### Pattern 3: Name-as-identity (~30 sites) - -String names used as semantic authority: `"Callable"`, `"Refined"`, -`"List"`, `"fold"`, `"first"`, `"last"`, magic type param names. - -**Ontological fix:** Partial dissolution. Each name stands for -a structural fact: -- `"Callable"` = the type of a Reduction (function type) -- `"Refined"` = Product with a constraint child -- `"List"` = FreeMonoid with arity 1 -- `"fold"` = catamorphic operation (structural facts in `AlgebraFieldTemplate`) -- `"first"/"last"` = FreeMonoid accessor with known size contract -Once the structural fact has a typed representation, the name -becomes rendering sugar (how it's displayed), not identity. - -### Pattern 4: Lossy boundaries (~10 sites in emit) - -TypeRendering erases connective. EmitGraphInfo partially erases -item identity. Downstream re-infers what was lost. - -**Fix:** TypeRendering must stop erasing connective. The existing -connective and TypeSummary.repr authorities should flow through -to the rendering layer. The 97-line `render_type_base` dispatch -collapses when it can read the existing authority directly. - -### Pattern 5: Duplicate authority (~8 sites) - -Same fact derived independently in multiple places: -`builtin_function_registry` vs algebra templates, `item_kind` vs -`classify_typed_item`, `is_zero_arg_func` vs `is_zero_arg_callable_ref`. - -**Fix:** Single authority per fact — consume existing structure, never -duplicate. Algebra operations come from the existing algebra profile. -Item identity comes from the existing Node fields. Nullary call status -comes from ExprVar→ExprCall normalization (making the expression IR -the sole authority). Each duplicate authority should be deleted in -favor of the existing one. diff --git a/src/v2/CM.md b/src/v2/CM.md deleted file mode 100644 index 7b5555a72d1..00000000000 --- a/src/v2/CM.md +++ /dev/null @@ -1,826 +0,0 @@ -# CM: Compiler Concept Modeling - -The compiler works but doesn't model what it does.

Reduction chosen as working - candidate for function application / computation steps. - **Caveat:** compilation itself is translation (structure-preserving - map between representations), not evaluation (reduction to normal - form). The emitter is a functor, not a reducer. See §Known gaps. -- **std/ representation?** Possibly `std/reduction.dag` with - Redex, RewriteRule, NormalForm. Must connect to Layers 4-6 - (iteration primitives are rewrite strategies, call patterns - are redex classifications). -- **Relationship to Morphism?** The Morphism property - (§Foundational principle) may be the static description - ("this Node is a rewrite rule") while reduction is the dynamic - description ("applying this rule is a computation step"). - -### Known gaps: where S/A/R doesn't help - -Stress-testing against the full heuristic inventory (CM-inventory.md) -reveals three areas the ontology does not cover: - -**Gap 1: Naming/Reference** — how you find the value - -Variable lookup, scope threading, alias resolution. These are about -the relationship between a symbol and its referent, not about what -the value IS or how it composes or what happens to it. - -| Problem | Math structure | -|---------|---------------| -| Variable lookup | Partial function application: `Name → Binding` | -| Scope/environment | Monoid action: environment acts on free variables | -| Alias resolution | Union-find: equivalence class representative | - -In sequent calculus terms, S/A/R covers the right side of the -turnstile (`⊢ e : T`). Naming covers the left side — the context -`Γ` that makes the judgment meaningful. - -**Gap 2: Multiplicity** — how many times a value is used - -Fan-out counting, clone/move/borrow decisions, sharing strategy. -The entire `ownership.dag` computes which structural rules of linear -logic apply to each binding: - -| Structural rule | Fan-out | ownership.dag | -|----------------|---------|---------------| -| Weakening | 0 | Dead code | -| Linearity | 1 | Move | -| Contraction | >1 | Rc + clone | - -Math: linear logic (Girard 1987), substructural type theory. This -is a modality on the logic (the exponential `!A`), not a new -connective — it modifies HOW Signal/Algebra/Reduction work, rather -than being a peer of them. - -**Gap 3: Maps between structures** — relating different algebras - -Coercion, TypeRendering, type equality. These are about relationships -*between* algebraic structures, not operations *within* one: - -| Problem | Math structure | -|---------|---------------| -| Coercion (Int → i64) | Functor: structure-preserving map between categories | -| TypeRendering | Forgetful functor: lossy projection with ad-hoc characterization | -| Type equality | Decidable congruence on Node | - -**Crucially: compilation itself belongs here, not under Reduction.** -The emitter translates between representations (a functor from .dag -algebra to target algebra). It does not evaluate/reduce programs. -This aligns with the existing invariant: "Emission is translation, -not decision-making." - -**Open:** Do these three gaps need their own std/ primitives, or are -they consequences of Signal/Algebra/Reduction applied at different -levels? Multiplicity may be a modality (orthogonal modifier). -Naming may be the application-of-partial-functions aspect of -Algebra. Functors may generalize Reduction to cross-structure maps. - -### Where CM does NOT help: fail-open analysis - -~39 sites in the inventory return fabricated defaults (unit_type, -empty string, false) when data is missing. Stress-testing these -against the CM analysis: - -| Category | Sites | CM helps? | -|----------|-------|-----------| -| Upstream data genuinely missing | bare_map_node contamination (04_resolve, 04_access), builtin registry (04_method) | **Yes** — modeling eliminates the fallback path | -| Bridge-era sentinels | Callable/Dynamic/Error suppression, rt_type policy | **Indirectly** — dissolves when builtins become .dag definitions | -| Defensive: unreachable post-inference | resolve_optional_node `None => unit_type` | **Not via modeling** — path is unreachable; function signature is too wide | -| Defensive: classification exhaustiveness | TypedItemUnhandled | **Not via modeling** — if-else can't prove completeness | -| Runtime semantics | char_at `""` on out-of-bounds | **No** — deliberate behavior choice | - -The genuine modeling gaps (~3 sites) trace to **one upstream root -cause**: `bare_map_node()` from inference not propagating expected -types through fold accumulators. This is the M2 open item already -on the ROADMAP. CM confirms but doesn't add to that diagnosis. - -**However: "defensive programming" is itself a modeling question.** - -The two defensive sites ARE structurally eliminable — at the -type-system level rather than the data level: - -- `resolve_optional_node` accepts `InferredNode?` but is only - called post-inference where `.inferred` is always `Some`. If - the function required `InferredNode` (non-optional), or if - post-inference Nodes were a distinct type with `.inferred` - guaranteed, the None path would be unrepresentable. - -- `TypedItemUnhandled` exists because an if-else chain can't - prove exhaustiveness. If the connective × body × transport - product space were a finite sum type with exhaustive match, - the unhandled case would be unrepresentable. - -The principle: every defensive guard is a place where the type -system can't prove what the programmer knows. The goal is not -"never write guards" but "push the proof into the structure so -the guard becomes a compiler error, not a runtime default." Some -guards are eliminable today (tighten function signatures); some -require richer type modeling (phase-indexed Nodes, finite product -decomposition); some are irreducible (runtime bounds checks on -external input). - -### Node and DAG as derived structure - -Node and DAG are treated as foundational ("Node is the only recursive -semantic authority" — ROADMAP). But they are not primitives. They are -compositions of the three foundational categories: - -**Node** = Product of: -- **connective**: Signal (Conj | Disj | NoConnective — structural assertion) -- **children**: FreeMonoid (Algebra — bounded recursive collection) -- **fields** (params, type_annotation, properties): Product (Algebra — conjunction of facts) -- **body | transport**: Reduction (rewrite rule — internal or external, or absent) - -**DAG** = FreeMonoid + PartialFunction> where acyclic -- Nodes form a collection (FreeMonoid) -- Edges are adjacency (PartialFunction) -- Acyclicity is a refinement constraint (same mechanism as `where non_empty`) - -The bounded kernel invariant restated: Node.children is FreeMonoid. -FreeMonoid is bounded by construction (finite list). The "only recursive -type" property falls out of using a bounded algebraic structure as the -carrier for self-reference — it's a theorem, not an axiom. - -**Connection to MM-1:** If Node decomposes along Signal/Algebra/Reduction, -then item classification is already answered by the structure: - -| Sugar | Signal (connective) | Algebra (fields) | Reduction | -|-------|---------------------|-------------------|-----------| -| `type` | Conj or Disj | structure fields | absent | -| `fn` | NoConnective | params, return | body (internal) | -| `service` | Conj | config, children | transport (external) | -| `resource` | Conj | capabilities | external identity | -| `data` | NoConnective | type constraint | body (ground term) | - -The classification forests (MM-1) exist because the compiler treats -Node as opaque and re-derives this decomposition. If the decomposition -were the API — if consumers asked "does this have Reduction?" instead -of "is this a function?" — the forests dissolve. - -### Validation: heuristic forests map to ontological categories - -Every heuristic forest in the per-file inventory (§below) asks about -one or two of the three categories. The reason the questions are hard -is impedance mismatch: the Node API exposes individual fields (`body`, -`transport`, `connective`, `params`, `uses`...) but the questions are -ontological ("has Reduction?", "what kind of Algebra?").

Four forests exist -because no one projection serves all consumers — but the source data -(Algebra? Reduction? What kind?) is identical across all four. - -**MM-2 sites** — almost entirely Algebra: - -| Site | Question | Category | -|------|----------|----------| -| `field_summary_for_type` | Conj → struct, Disj → enum | Algebra (product/coproduct) | -| `build_type_summary` | StructRepr vs EnumRepr | Algebra | -| `render_type_base` (97 lines) | 7-way string/field dispatch | **Lost Algebra** — connective erased by TypeRendering | -| `build_type_rendering` "Callable" | `n.name == "Callable"` | Reduction ("is this a function type?") | - -The 97-line `render_type_base` exists because TypeRendering is a lossy -boundary: it flattened Algebra (connective) into string names and -optional fields.

Every downstream stage re-derives item -kind from the same bag of fields: `{connective, body, transport, params, -children, uses, type_annotation, properties}`. - -**Symptoms:** Four independent classification forests, three with -different output taxonomies: - -| Stage | Location | Branches | Output | -|-------|----------|----------|--------| -| Item analysis | `04_items.dag:114-131` | 8 | `ItemKind` (FnItem/FuncItem/TypeItem/DataItem/ServiceItem/OtherItem) | -| Type env registration | `04_infer.dag:2270-2326` | 5 | Registration strategy (full type / alias / nominal / parameterized / resource) | -| Emit classification | `04_emit_info.dag:75-104` | 9 | `TypedItemKind` (Struct/Enum/TypeAlias/TypeDecl/Function/TransportFunction/DataDef/ServiceDef/ResourceDef/Unhandled) | -| Value constancy | `04_infer.dag:2972-3050` | 5 | Boolean (is_constant) | - -Plus downstream consumption: name-keyed `Map`, -name-keyed `Map`, etc. — each with fail-open -fallbacks that fabricate defaults on miss. - -**The question:** What are the irreducible structural facts about an -item? Not "is this a function?" (interpretation) but "does it have a -body? does it have a transport? does it have structure?" The fields -themselves ARE the facts. The four taxonomies are redundant -interpretations that exist because no single taxonomy felt complete. - -**Design direction:** Stop classifying. The fields (`body`, `transport`, -`connective`, `params`, `uses`) ARE the structural facts. Consumers -should pattern-match on the facts they need directly — "does this have -a body?" not "is this a FnItem?" Adding a `ClassifiedItem` wrapper -would create a duplicate authority alongside the existing fields. -The fix is making the existing fields reachable at every consumption -site, not wrapping them in a new taxonomy. - -**Subproblems:** -- `is_type_alias_return_node` special-cases string `"Unit"` (`04_emit_info.dag:69`) -- `TypedItemUnhandled` is a fail-open sentinel — should be impossible by construction -- ServiceFieldSet / FunctionSignature / ResourceDefinition stored in name-keyed side-tables - ---- - -### MM-2: Type structure ("product, sum, or leaf?") - -**The gap:** `Conj/Disj/NoConnective` is a primitive, but its -*interpretation* (product → struct rendering, sum → enum rendering, -leaf → primitive lookup) is re-derived at every site. - -**Symptoms:** 277 `Conj/Disj/NoConnective` references across .dag files. -Key sites: - -| Location | What it decides | -|----------|----------------| -| `04_lookup.dag:209-294` | Field access resolution path | -| `04_emit_info.dag:607-633` | TypeSummary (StructRepr vs EnumRepr) | -| `05_emit.dag:1095-1191` | 97-line type rendering dispatch | -| `04_types.dag:367-415` | Type equality | -| Every `emit_typed_item` | Struct vs enum code generation | -| `complexity.dag` | Structural analysis | - -**Design direction:** The connective primitives stay — they're -foundational. The connective IS the authority. `TypeSummary.repr` -(StructRepr/EnumRepr) already exists as a downstream consumer of -connective — the question is whether all consumers should read -connective directly (the minimal model) or whether TypeSummary.repr -should become the single derived consumer that others go through. - -Adding a new TypeShape enum would create a third authority alongside -connective and TypeSummary.repr — a duplicate representation -violation. The fix is to make connective reachable to every consumer -that currently re-derives it, not to add another interpretation layer. - ---- - -### MM-3: Expression semantics ("what does this reference/call do?") - -**The gap:** Method and function identity is a string. Every consumer -dispatches on name. - -**Symptoms:** - -| Location | Branches | Dispatch | -|----------|----------|----------| -| `05_emit_rust.dag:2853-2901` | 13 | Algebra method name (fold/map/filter/sort_by/...) | -| `04_infer.dag:842-903` | 7 | Collection method result type | -| `04_infer.dag:1215-1258` | 4 | Built-in call type refinement (lookup/map_get/...) | -| `04_infer.dag:1130-1189` | 5 | Call tier (known sig → method bridge → special case) | -| `complexity.dag` (distributed) | 5+ | Method classification for progress analysis | -| `05_emit_rust.dag:1748-1750` | 3 | Nullary function ref → append `()` | - -**Subproblem — nullary invocation (from CG review):** - -In DAG, referencing a nullary function IS invoking it — no `foo()` vs -`foo` distinction. Target languages need `()`. Currently the emitter -re-derives this from type names or registry lookups (`04_emit_rust.dag` -lines 1685-1750). Inference already knows at `04_infer.dag:970-977`: -`binding_kind = FunctionValueBinding` + `fsig.params |> count == 0`. - -**Design direction:** Normalize ExprVar → ExprCall during inference -when the reference IS an invocation. The expression IR is the authority -for invocation semantics — the graph should represent what the program -DOES, not what the surface syntax LOOKS like. Inference already knows -(`binding_kind = FunctionValueBinding` + zero params); the fix is to -act on that knowledge by rewriting the expression node. - -Adding `NullaryCallBinding` to `VarBindingKind` would encode invocation -semantics on binding classification (a workaround) instead of the -expression IR (the root cause). This violates Root-Cause Depth — the -fix belongs at the expression level, not the binding level. - -Note: Go and Python emitters completely ignore `binding_kind` today — -they destructure with `_` and emit bare identifiers. They have the -same nullary bug. ExprVar→ExprCall normalization fixes all three -backends at once because the authority is in the expression, not the -binding. - -**Design direction for method dispatch:** The `method_def` Node and -the algebra framework (`AlgebraProfile`, `AlgebraFieldTemplate`) -already carry method identity structurally. The fix is to surface -these existing authorities to downstream consumers (emit, complexity) -through the pipeline boundary, not to add a parallel -`AlgebraMethodKind` enum. Adding a new dispatch enum would duplicate -the existing method_def authority — a No-duplicate-representations -violation. The method_def Node IS the method identity. - ---- - -## Per-file heuristic inventory - -Dense reference for when we start fixing these. - -### 04_emit_info.dag (662 lines) - -| Lines | Heuristic | Missing model | -|-------|-----------|---------------| -| 65-70 | `is_type_alias_return_node`: `n.name != "Unit"` | MM-1: name-driven alias detection | -| 75-104 | `classify_typed_item`: 9-branch if-else | MM-1: item classification | -| 107-111 | `lookup_item_kind`: `None => TypedItemUnhandled` | MM-1: fail-open fallback | -| 127-152 | `classify_service_fields`: transport scanning | MM-1: service facts | -| 155-159 | `lookup_service_fields`: fabricates `{false,false,false,false}` | MM-1: fail-open | -| 607-633 | `build_type_summary`: connective dispatch | MM-2: type structure | - -### 04_items.dag (250 lines) - -| Lines | Heuristic | Missing model | -|-------|-----------|---------------| -| 114-131 | `classify_item`: 8-branch if-else | MM-1: item classification (duplicate #2) | -| 83-112 | Output derivation: connective + name checks | MM-2: type structure | - -### 04_infer.dag (3159 lines) - -| Lines | Heuristic | Missing model | -|-------|-----------|---------------| -| 842-903 | Collection method result type: 7-way name match | MM-3: method identity | -| 1008-1070 | Field access resolution: 5-branch cascade | MM-2: type structure | -| 1130-1189 | Call tier classification: 5-branch cascade | MM-3: call identity | -| 1215-1258 | Built-in call refinement: 4-way name match | MM-3: method identity | -| 1642-1670 | Lambda element type threading: 5 branches | MM-3: callable shape | -| 2270-2326 | Type env registration: 5-branch classification | MM-1: item classification (duplicate #3) | -| 2526-2527 | `is_zero_arg_func`: re-derived from params | MM-3: nullary invocation | -| 2972-3050 | `is_item_constant`: 5-branch value analysis | MM-1/MM-2: item + type structure | - -### 05_emit_rust.dag (4598 lines) - -| Lines | Heuristic | Missing model | -|-------|-----------|---------------| -| 1685-1750 | `emit_var_ref`/`emit_typed_expr_base`: 3-tier nullary detection | MM-3: nullary invocation | -| 2286-2338 | Index dispatch: string-like vs map vs list | MM-2: type structure (string-like) | -| 2853-2901 | Algebra method dispatch: 13-way name match | MM-3: method identity | -| 2944-2957 | Match scrutinee Rc handling: 4 branches | MM-2: ownership shape | -| 3101-3123 | Field optionality: 3 fallback attempts | MM-2: field metadata | -| 3170-3217 | Variant parent lookup: 4 fallback paths | MM-1: variant identity | -| 3219-3239 | Struct name from field set: heuristic matching | MM-1: type identity | -| 3881-3897 | Shell return type dispatch: 4 branches | MM-2: type structure | - -### 05_emit.dag (1715 lines) - -| Lines | Heuristic | Missing model | -|-------|-----------|---------------| -| 922-930 | `"Callable"` name check for type rendering | MM-2/MM-3: callable type | -| 1095-1191 | Type rendering dispatch: 97 lines, 7 branches | MM-2: type structure | - -### 05_emit_go.dag / 05_emit_python.dag - -| Lines (Go/Py) | Heuristic | Missing model | -|-------|-----------|---------------| -| 371-406 / 363-406 | `emit_*_typed_item`: kind dispatch + fail-open `""` | MM-1: item classification | -| 609 / 591 | `emit_*_expr_var`: ignores `binding_kind` entirely | MM-3: nullary invocation (bug?) | -| 822-843 / 801-824 | Index dispatch: string-like check | MM-2: type structure | -| 373 / 366 | `unit_only` lookup: `None => false` | MM-2: fail-open fallback | - -### 00_core.dag (1441 lines) - -| Lines | Heuristic | Missing model | -|-------|-----------|---------------| -| 1038-1041 | Transport predicates: `t.name == "rest"` etc. | MM-1: transport identity (4 string comparisons) | -| 1060-1092 | Transport property accessors: string keys | MM-1: transport structure | - -### complexity.dag (4363 lines) - -| Lines | Heuristic | Missing model | -|-------|-----------|---------------| -| 566-580 | `extract_base_var_name`: pattern-match on ExprData | MM-3: expression identity | -| 737-765 | `classify_call_progress`: witness-based dispatch | MM-3: call semantics | -| 1393-1500+ | `max_path_self_calls_with_cont`: ExprData dispatch | MM-3: expression semantics | -| distributed | `mname == "first" || mname == "last"` repeated | MM-3: method identity | - ---- - -## Cross-cutting patterns found in open PRs / recent main - -These aren't new problems — they're the same three models showing up in -every change. - -**PR #321 (CG lane):** Moved `has_fn_fields` and `is_constant` into -TypeSummary (good — dissolves re-derivation).

The existing authorities -(Node fields, connective, method_def, AlgebraFieldTemplate) are the -ground truth. The fix is making them reachable at every consumption -site. If a boundary needs to carry facts to a consumer, it must be -exact and non-lossy — no stripping of data the consumer needs, no -new parallel interpretation types. This means: -- No new `ItemKind`/`TypeShape`/`AlgebraMethodKind` classification types -- No lossy boundary that drops distinctions downstream consumers need -- The existing structural data flows through stage boundaries intact - -### MM-1: Item re-classification dissolves - -**Problem:** Four classification forests re-derive item kind from -raw Node fields because the fields aren't reachable at the boundary. - -**End-state:** The existing structural fields (`body`, `transport`, -`connective`, `params`, `uses`) flow through the infer→emit boundary -intact. Emit reads them directly — not from side-tables, not from a -parallel classification type, not re-derived from heuristics. The -four classification forests dissolve because every consumer reads the -same structural facts from the same Node. - -**Constraint:** This does NOT mean emit performs ad-hoc semantic -interpretation of raw fields. The fields themselves are the semantic -facts (body = has internal evidence, transport = has external -grounding, connective = structural composition). Reading a field is -reading the authority, not re-deriving it. - -**Edge cases (from analysis):** Some field combinations are -semantically ambiguous (empty service, resource with properties but -no capabilities, fn/interface/pattern producing identical shapes). -These should be resolved at the parser or normalizer — not left for -downstream to improvise. See §Arity boundaries below. - -### MM-2: Connective re-interpretation dissolves - -**Problem:** 57 sites re-derive "product or coproduct?" from -connective. - -**End-state:** Connective is the authority. `TypeSummary.repr` -(StructRepr/EnumRepr) is the existing derived consumer for emit. -The fix is extending `TypeSummary.repr` to cover all type rendering -(not just type definitions). `TypeSummary.repr` is only safe as the -single authority if it is proven non-lossy — it must preserve every -distinction that lookup, types, complexity, and ownership need, not -just emit. If it collapses distinctions that other consumers need, -those consumers should read connective directly. - -**Constraint:** No new TypeShape enum. Either connective or -TypeSummary.repr is the authority at each site, never both. - -### MM-3: Method name dispatch dissolves - -**Problem:** 21 sites dispatch on `method_def.name` strings. - -**End-state:** The `method_def` Node and `AlgebraFieldTemplate` -already carry method identity (parameter types, return type, receiver -shape). Emit reads these structural facts instead of matching on -name strings. Nullary function invocation is ExprCall in the IR -(normalized during inference), not detected by type-name checks. - -**Constraint:** The algebra framework IS the method identity -authority. The fix is surfacing `AlgebraFieldTemplate` facts through -the pipeline — not adding a parallel enum. For nullary calls, the -expression IR is the authority (ExprVar→ExprCall normalization). - ---- - -## Arity boundaries: where the model is silent - -Open-ended modeling (Node with optional fields, containers with -variable children) produces a combinatorial space much larger than -the set of semantically valid configurations. At the boundaries — -arity 0, arity > expected, ambiguous field combinations — the model -is silent and code improvises. Each improvisation is a future refactor. - -### Node field combinations - -Three keywords (`fn`, `interface`, `pattern`) produce identical field -shapes. The keyword dissolves after parsing — downstream can't -distinguish intent. Two independent classifiers (`item_kind` in -04_items.dag, `classify_typed_item` in 04_emit_info.dag) operate -on the same Node field space with different priority chains and -**can disagree** (resource with properties but no capabilities: -item_kind → OtherItem, classify_typed_item → ResourceDef). - -Ambiguous combinations the parser produces but nobody specified: - -| Combination | Parser accepts? | Semantic question | -|-------------|----------------|-------------------| -| Service with 0 operations | Yes | Valid (forward decl)? Or error? | -| Resource with 0 capabilities | Yes | Valid? Hits TypedItemUnhandled | -| fn with only type params, no value params | Yes | Body can't use params at value level | -| interface → identical shape as fn | Yes | Intent lost after parsing | - -**Principle:** Each ambiguous combination should be resolved at the -parser or normalizer — not left for downstream to improvise. If the -combination is valid, its semantics must be specified. If invalid, -the parser should reject it (construction over ratchets). - -### Container arity boundaries - -`container_type_arity` covers List(1), Map(2), Set(1) but is silent -at the boundaries: - -| Scenario | What happens | Should happen | -|----------|-------------|---------------| -| `Map` (under-arity) | Silently filled to `Map` | Diagnostic or expected-type propagation | -| `List` (over-arity) | Falls through all predicates | Diagnostic: arity mismatch | -| `Optional>` | Collapses to `Optional` silently | Document or diagnose (idempotent optionality) | -| Callable/lambda param mismatch | Excess gets TypeVariable | Diagnostic: arity mismatch | -| `index` on FreeMonoid | Declared as T (non-optional) | Should be T? (partial function) | - -Types not in `container_type_arity` at all: Optional, Callable, -Tuple, FreeMonoid, PartialFunction, BooleanAlgebra. These have no -arity validation even for the common case. - -**Connection to fail-open:** The `bare_map_node()` chain (§fail-open -analysis above) is a specific instance of this pattern. When arity -is unvalidated, under-parameterized types propagate through the -pipeline and force downstream fallbacks. - -**Principle:** Arity constraints should be declared once (in the -algebra profile or type declaration) and enforced at normalization. -Over-arity and under-arity should produce diagnostics, not silent -patches. The algebra profile already carries parameter counts — the -normalizer should read them. - ---- - -## Foundational principle: classification is not primitive - -The heuristic forests exist because the compiler classifies nodes into -categories (type, function, service) that are not primitive concepts. -They are surface sugar — named compositions of more fundamental -properties. See `MODELING.md §four-layer model`: - -``` -Surface sugar: service, fn, type, operation (user intent) -Composition layer: Node, children, edges (how things connect) -Semantic kernel: types, effects, contracts (what flows through nodes) -Foundation: logical algebra (why it's sound) -``` - -`MODELING.md` already states: *"The sugar informs the parser what fields -to expect. It does not flow into the compiler core as identity."* - -The compiler violates this. Surface identity (is-this-a-function, -is-this-a-service) leaks into every stage — not as an explicit concept, -but as implicit field-presence heuristics that re-derive it. The -classification forests are the compiler re-inventing surface sugar -because it doesn't have the underlying primitives. - -### What the classifications are really asking - -Every classification forest is asking about combinations of a few -orthogonal properties. These properties are already on Node but are -not named as concepts: - -| Property | What it means | Foundation | Ontological category (§above) | -|----------|---------------|------------|-------------------------------| -| **Structure** | Node asserts a data shape (connective + children) | Conjunction/Disjunction — logical structure | Algebra | -| **Evidence** | Node provides backing for its claim (body = internal, transport = external) | Witness/proof — epistemic | Signal | -| **Morphism** | Node describes a mapping (params → return type) | Implication — logical entailment | Reduction (rewrite rule) | - -Structure/Evidence/Morphism are **analysis vocabulary** — a way to -talk about what existing Node fields mean. They are NOT proposed as -stored metadata or a new boundary layer. The heuristic forests exist -because consumers re-derive these properties from raw Node fields -instead of reading the fields directly. The fix is making the fields -reachable, not adding a Structure/Evidence/Morphism annotation. - -The surface sugar composes these: - -| Sugar | Decomposition | -|-------|---------------| -| `type` | Structure, no evidence (the claim IS the structure) | -| `fn` | Morphism + internal evidence | -| `func` | Morphism + internal evidence + external binding | -| `service` | External evidence + structured children (operations) | -| `resource` | Structure + external identity (capabilities) | -| `data` | Internal evidence + type constraint (ground term) | - -The downstream consumer never needs to know "is this a function?" — it -needs to know "does this have a morphism?" and "does this have internal -evidence?" Those are the actual questions. The classification is a -lossy proxy for them. - -### The pattern: concepts are emergent, not primitive - -This is the same pattern as recursion. "Recursion" was treated as a -concept that needed to be detected and classified (is this safe? is -this tail-recursive?). In reality, recursion is emergent from three -primitives: fold (structural descent), descend (child traversal), and -repeat (bounded iteration). Once the primitives were modeled, the -classification problem dissolved — you didn't need to ask "is this -safe recursion?" because the primitives were safe by construction. - -The same principle applies here: - -- **Item classification** (MM-1): "type/function/service" are emergent - from structure/evidence/morphism. Model the primitives and the - classifications become sugar that the parser uses and the compiler - doesn't need. - -- **Type structure** (MM-2): "product/sum/leaf" are emergent from - connective (already primitive). The missing piece is a named - interpretation that the compiler can consume without re-deriving. - Connective IS the primitive — it just needs to be the vocabulary - the compiler thinks in, rather than something it checks via - `.connective == Conj`. - -- **Method identity** (MM-3): "fold/map/filter" are emergent from - algebraic structure. A fold is a monoid homomorphism. A map is a - functor application. A filter is set comprehension. The algebra - framework (`AlgebraFieldTemplate`) already carries this identity — - the missing piece is surfacing it through the pipeline to consumers - that currently dispatch on name strings instead. - -### Design direction - -The goal is not to carry classification forward from the parser, but -to model the underlying primitives so classification is unnecessary. -The compiler should work at the composition and semantic kernel layers, -never at the surface sugar layer. When it needs to dispatch, it -dispatches on primitives (structure? evidence? morphism?), not on -named compositions (type? function? service?). - -This means the primitives need to be modeled in `dsl/std/` — the same -way connective, cardinality, and algebraic structure already are. -They become part of the shared concept library that the compiler both -generates code for and consumes. The compiler moves parts of itself -into higher-level abstractions that it itself processes. - -### Practical principles - -1. **Surface sugar does not flow past the parser.** If the compiler - asks "is this a function?" it's using sugar as identity. - -2. **Classify by dispatching on primitives, not named compositions.** - The question is "does this have evidence?" not "is this a function?" - -3. **If a concept keeps getting re-derived, it's a missing primitive.** - The re-derivation is the compiler telling you what it needs modeled. - -4. **Unrepresentability over discipline.** Design the types so the - wrong question can't be asked, not so that people avoid asking it. - -5. **The graph represents semantics, emission only renders.** If the - emitter makes a semantic decision, that decision belongs upstream - in the semantic kernel. - -6. **Consume existing authorities, never duplicate them.** When a - downstream consumer needs a fact, the fix is to surface the existing - authority through the pipeline — not to derive a parallel - representation. Adding a new TypeShape alongside connective, or a - new AlgebraMethodKind alongside method_def, is `a + 0 = a` - reimplemented as `identity_check(a) → a`. The mathematical minimum - is one authority per fact. Ontological analysis (Signal/Algebra/ - Reduction) helps identify what the heuristics are asking; the fix - is always "make the existing answer reachable," not "add a new - answer." diff --git a/src/v2/DESIGN.md b/src/v2/DESIGN.md deleted file mode 100644 index e103470d0dc..00000000000 --- a/src/v2/DESIGN.md +++ /dev/null @@ -1,83 +0,0 @@ -> Part of: [THESIS.md](../../THESIS.md) > [ROADMAP.md](../../ROADMAP.md) > [docs/architecture.md](../../docs/architecture.md) - -# v2 Compiler Design Principles - -These are the governing design decisions for the self-hosted compiler. -For current status, phases, and workboards, see [ROADMAP.md](../../ROADMAP.md). -For invariants, see [INVARIANTS.md](../../INVARIANTS.md). - -## Core claim - -The compiler is a pure transform: `.dag source → backend artifacts`. -Five stages, each a pure function: - -``` -.dag source → tokenize → parse → resolve → typecheck → emit → output files -``` - -No interpreter in the pipeline.

A `String` is wrong -when it chooses behavior. The rule, stage by stage: - -| Stage | String rule | -|---|---| -| **Before resolve** | Strings are allowed as source payload (token text, identifiers, keywords) | -| **At resolve** | Strings are consumed to produce edges. Scope maps are resolver-local and die here. | -| **After resolve** | **No semantic decision may depend on free text.** Anything that changes behavior must be an edge/reference, a closed enum, or a typed boundary fact. | -| **In emit** | Only the renderer may produce strings. Shared emit walks the graph and invokes the renderer — it never returns `String`. | - -This is the existing invariants restated as an API law: names are -opaque, boundaries must be sufficient, heuristics mean a fact was lost. - -## What's legitimate as String - -- Token.text, file paths, module paths (source payload) -- Identifiers during parse, before resolution (frontier artifact) -- Diagnostic messages (human-facing payload) -- TextFile.content and LanguageSpec templates (final rendered text) -- Resolver-local scope maps that die at the resolution boundary - -These are text.

The question -is never "string or DAG?" — it's "does this string carry text, or does -it choose behavior?" - -## Three bypasses to defend against - -Even after cleanup, these can reopen the escape hatches: - -**1. `source_text_at(span)` as a semantic API.** Deleting `Node.name` -is not enough if infer/complexity/ownership re-read text from spans. -After resolve, source text must be a privileged capability available -only to renderers and diagnostics — not to semantic stages. - -**2. String return types on emit functions.** The emitter must not -return `String`. It returns the typed graph; the renderer produces -text. No intermediate string-producing IR is needed because the -compiler's output IS the graph. - -**3. "Temporary" stringly side tables.** `Map` looks -harmless, but once it crosses a stage boundary it becomes a second -authority. The invariants say: speculative or lossy boundary fact -tables should be deleted rather than carried forward. "Temporary" -without a ratchet means "permanent later." - -## Backend model: graph coercion - -The backend is a graph->graph coercion engine. The graph structure -tells the compiler WHAT kind of coercion is needed. It does NOT always -tell the compiler HOW to discharge the proof — some steps need -evidence or explicit transforms. - -``` -typed graph -> carrier + constraint analysis -> coercion plan -> target-basis graph -> renderer -``` - -Note: "subgraph" is too literal as the universal test. The real -relation is **carrier compatibility + constraint entailment** — same -carrier with fewer guarantees (widen), same carrier with more -guarantees (refine/validate), or different carrier entirely -(transform/lower). - -### Five coercion kinds with witnesses - -| Kind | What happens | Witness | Implicit? | Example | -|---|---|---|---|---| -| **Widen** | Erase guarantees | `Free` | Yes | `Url -> String` (predicate erasure) | -| **Refine** | Add guarantees already proven by structure | `Proven` | Yes | `NonEmpty>` -> compiler sees non-empty evidence | -| **Validate** | Add guarantees by runtime check | `Checked` | No — explicit `as` or inserted check, visible in receipt | `String -> Url` (needs URL validator) | -| **Project** | Lose structural information | `Lossy` | No — explicit acknowledgment | `List -> Set` (loses order), `Float -> Int` (truncate) | -| **Transform/Lower** | Compute new representation | `Transformed` | No — `.dag` process or plugin lowering | `Celsius -> Fahrenheit` (domain), coproduct -> SPICE mux (backend) | - -**Key distinctions:** - -- **Upcasts (widen) are implicit.** Free, no evidence needed. -- **Refinements with proof already present are implicit.** The graph - carries the evidence; the compiler reads it. -- **Downcasts (validate) are NOT generally implicit.** Only the subset - already proven by structure is implicit. Everything else needs an - explicit check — otherwise we reintroduce hidden fabrication. -- **Transform and lower are separate concerns that share a mechanism.** - `Celsius -> Fahrenheit` is a user-space domain transform. - `coproduct -> SPICE mux` is a backend lowering. Both need authored - `.dag` processes, but they're not the same category — domain - transforms live in user/library code, backend lowerings live in - language plugins. - -**Key insight: most domain transforms dissolve with proper modeling.** -If Celsius and Fahrenheit both model absolute temperature through -Kelvin (a shared structural base), the compiler finds the path: - -``` -Celsius -> Kelvin (widen/refine: same carrier, offset transform) -Kelvin -> Fahrenheit (widen/refine: same carrier, scale + offset) -``` - -Both legs have proven witnesses.

Insert url_parse(s) or use as_url(s)." - The check is visible in the guarantee receipt. - -PROJECT (explicit, Lossy): - List -> Set -- compiler shows: "target lacks position, multiplicity. - Use to_set(list). Acknowledge: order lost, duplicates removed." - -TRANSFORM (explicit .dag process, Transformed): - Celsius -> Fahrenheit -- through Kelvin shared base if modeled. - Otherwise: user writes fn to_fahrenheit(c: Celsius) -> Fahrenheit. - -LOWER (plugin .dag process, Transformed): - coproduct -> SPICE mux -- language plugin declares the lowering. - Lives in dsl/extdeps/languages/spice/coerce.dag, not in user code. -``` - -**The guarantee receipt records every non-Free step:** kind, witness -type, what evidence was used (or what check was inserted, or what -process was invoked). No silent coercions. The receipt is the audit -trail. - -**For language targets, the same model applies:** - -A language declares its **basis** — which structural patterns it can -represent natively. The compiler compares each source graph segment -against the basis: - -| Source pattern | Target basis has it? | What happens | -|---|---|---| -| Product | Rust: struct | **Identity** — same structure, different syntax | -| Coproduct | Rust: enum | **Identity** | -| Coproduct | SPICE: no native tagged union | **Isomorphism** — mux from switches is structurally equivalent (one-of-N selection) | -| Cardinality | Verilog: tri-state | **Identity** | -| Function | English: paragraph | **Identity** | - -When the source pattern IS in the target's basis -> identity (free). -When it's NOT -> the compiler looks for a structural isomorphism in -the target's basis (e.g., coproduct <-> mux: both are one-of-N -selection). The language plugin declares these isomorphisms in -`coerce.dag`. The compiler doesn't guess — it follows declared -structural equivalences. - -**Why this avoids duplicate representations:** the graph IS the type -relationship. Widening, narrowing, and projection are structural -observations — the compiler reads them from the graph. Isomorphisms -through shared bases are structural paths — the compiler finds them. -Only language-specific structural equivalences (coproduct <-> mux) -need to be declared, and those are properties of the target domain, -not rules duplicated from the source types. - -**Rendering happens AFTER coercion.** The renderer walks the -target-basis graph (already in native patterns) and produces text. -Trivial. All intelligence is in the structural comparison (automatic) -and the sidecast processes (authored in `.dag`). - -**The guarantee receipt records the coercion plan:** for each graph -segment, what direction (upcast/downcast/sidecast), what cost, what -the sidecast process was (if any).

Input = (param1, param2, ...), -output = (arg1, arg2, ...) of the recursive call. Termination = some -component of the combined state strictly decreases, none increases -unboundedly. - -In this framing: -- **Lambda transparency dissolves.** A lambda `x => self(n: x)` passed - to `f(texpr: texpr, callback: ...)` is a composed transition: - f extracts sub-values of texpr → passes to callback → callback - passes to self. Evidence composes through the lambda boundary. -- **Multi-dimension dissolves.** (keys shrinks, template varies) is - a single transition that's well-founded because the keys component - is bounded. -- **Bounded ascent dissolves.** (pos increases, length stays) is - well-founded when the pair is considered: pos < length. - -The call graph already composes through function boundaries (SCC -detection recurses into lambda bodies). The evidence system doesn't. - -### Open question: how to implement compositional evidence - -Two approaches under consideration: - -**Callee contract declarations.** Higher-order functions declare -contracts about how they invoke callback parameters: -``` -type CallbackContract { - function_name: String - callback_param: String - source_param: String - relation: SubValueRelation -} -``` -This extends the existing AlgebraMethodSemantics pattern. Contracts -are declared in std/, checked once, consumed by callers. Localized -change to annotate_descent. - -**Full state-transition model.** Instead of per-parameter evidence, -track combined state transitions across function boundaries. More -compositional but requires rethinking the evidence lattice from -SubValueRelation (per-param) to TransitionEvidence (all params). - -The callee contract approach is a stepping stone toward the full -model — it addresses lambda transparency with minimal disruption. -The full model may be needed for multi-dimension and bounded-ascent -categories. - ---- - -## Concrete modeling decisions (ledger) - -### Decided - -| Decision | Rationale | Where | -|----------|-----------|-------| -| ProgressKind → DescentEvidence | Parallel lattice with bridge functions was redundant | PR #370.

Lambda body opacity** (`04_infer.dag:745`) - -When a lambda parameter is bound, inference stores: -`TypeBinding { name: p, resolved: type_variable_node("lambda_param") }`. -The parameter gets a placeholder type.

Match arm provenance** (`04_infer.dag:773-799`) - -When `match param { Cons { head, tail } => ... }` creates bindings, -inference knows that `tail` is a strict sub-value of `param` via -variant `Cons`, field `tail`. It stores: `TypeBinding { name: "tail", -resolved: }`. The variant name, field name, and structural -relationship are gone. - -**4. For-each element provenance** (`04_infer.dag:1915-1933`) - -When `children |> map(c => ...)` creates the binding for `c`, -inference knows `c` is an iterated element of `children`.

If `Node` has -`children: List`, then iterating over `children` is structural -descent — period. This is derivable from the type. - -The complexity analyzer should never need to know about specific -accessor functions (`let_value`, `field_access_base`, `child_type_node`). -It reads from the type that certain fields carry recursive sub-structure. -The accessor is just a projection — the descent fact lives in the type. - -**Implication:** Hand-maintained tables like `function_size_effects`, -`expr_child_roles`, `node_field_roles` should dissolve into facts -derived from type declarations. Adding a new accessor function should -require zero changes to the complexity analyzer. - -### P2: The pipeline preserves facts — never constructs, discards, and reconstructs - -Every structural fact the compiler computes must be preserved in the -IR from the point of computation to the point of consumption. The -complexity analyzer is a **consumer** of structural facts, not a -producer or reconstructor. - -**The invariant:** at no point in the pipeline should information be -computed, stored in a lossy representation, and then re-derived -downstream via heuristics. If a stage computes a fact, it either: -1. Stores it in the IR for downstream consumers, or -2. Is the final consumer (no downstream re-derivation needed) - -This is the same principle as fail-closed diagnostics -(INVARIANTS.md): if the compiler knows something, it must not -discard it and hope a later stage can figure it out. - -**Current violation:** `TypeBinding { name, resolved }` discards -provenance. `annotate_descent_evidence` reconstructs it. This is -the root cause of the 33 reconstruction heuristics and 424 CX -violations. - -### P3: Every pattern has a bound — but Forever and Unknown are distinct - -Every **structurally lowerable** call pattern has a finite bound. -`self(same_arg)` -> `repeat(Forever)`. The analyzer computes bounds -for patterns it can lower. - -**Fail-closed:** If the analyzer cannot classify a call pattern — -because descent evidence is missing, not because the pattern is -`repeat(Forever)` — compilation fails with a hard error. This is -`Unknown`, not `Forever`. They are categorically different: - -- `Forever` = concrete bound for an actual repeat loop (2^63-1). - The code IS structurally lowerable. The bound is honest. -- `Unknown` = the analyzer cannot prove a bound. Hard error. - The code may need restructuring, or the analyzer is incomplete. - -**Forever factoring:** A bound like `Forever x n` decomposes into: -- **Termination character:** runs forever (server loop, event loop) -- **Per-iteration scalability:** O(n) in tree size - -The bound algebra supports factoring. Forever is honest (not hidden -or rejected) but separated from the scalability analysis. - -### P4: Global descent, not strict monotonicity - -The current analyzer requires every self-call to strictly decrease -some measure. Real programs take detours — a function may temporarily -preserve or even increase a measure before eventually decreasing it. - -**What matters:** over every complete cycle of the computation, -some well-founded measure decreases. Individual steps may not -decrease, as long as no infinite non-decreasing sequence exists. - -**Phasing:** Start with strict descent (handles the vast majority -of real patterns). Design the abstraction so it can be relaxed later. -The interface between pipeline and analyzer should be an opaque proof -object that accommodates lexicographic, size-change, or amortized -proofs. - -### P5: Complexity classes are emergent - -Linear, quadratic, Forever are emergent properties of the bound -algebra. The analyzer doesn't classify — it computes a bound, and -the complexity class falls out. - -**Implication:** No `classify_complexity` function. The bound IS the -classification. `O(n)` emerges from `bound = TreeSize(param)`. -`O(n*m)` emerges from nested iteration bounds. - -### P6: Recursion is emergent - -Recursion is not a first-class concept to model or analyze. It falls -out of functions calling each other. Only iteration primitives -(fold/descend/repeat) are modeled explicitly because they are -intentional developer constructs. - -The analyzer never tries to "prove recursion terminates" — it computes -the tightest bound it can from structural facts about data and -operations. - ---- - -## Two viable paths - -Both paths eliminate the construct-discard-reconstruct anti-pattern. -They differ in WHERE the iteration primitive identity is captured. - -### Option A: Desugar recursive syntax to primitives - -The language already says "recursive syntax is sugar" -(`std/iteration.dag:53`). Option A commits to this: the parser (or -an early compiler pass) rewrites recursive functions to explicit -primitive form. - -``` -// User writes: -fn simplify(expr: CostExpr) -> CostExpr { - match expr { - CostAdd { left: l, right: r } => - CostAdd { left: simplify(l), right: simplify(r) } - _ => expr - } -} - -// Compiler lowers to: -descend(expr, f: (node, children) => - match node { - CostAdd { left: _, right: _ } => - CostAdd { left: children[0], right: children[1] } - _ => node - } -) -``` - -**What dissolves:** The entire CX-L2/L3 pipeline. There is no -recursive call to analyze — the primitive IS the cost fact. -`descend` costs O(|tree|). `fold` costs O(|collection|). Done. - -**Pros:** -- Simplest possible model. Cost is a property of the primitive, not - a derived analysis. -- Zero reconstruction. The desugared form carries its own cost. -- Aligns with `std/iteration.dag`'s stated position. - -**Cons:** -- Requires a desugaring pass that correctly classifies every - recursive pattern (same classification problem, different location). -- Changes internal representation significantly — all downstream - passes (emit, ownership) see desugared form. -- User error messages must map back to original syntax. -- The desugaring pass itself needs the same structural knowledge - (which fields are recursive, which calls descend). - -**Viability concern:** The desugaring pass needs to solve the same -classification problem that CX-L2 currently solves. The difference -is that it solves it ONCE (at desugar time) rather than reconstructing -it later. This is strictly better — but the classification work -doesn't disappear, it moves. - -### Option B: Thread existing SubValueRelation through bindings (preferred) - -The sound foundation already exists: `SubValueRelation` in -std/induction.dag models exactly the right vocabulary -(StrictSubValue, IteratedSubValue, ArithmeticDescent, PreservedValue, -SubValueUnknown) with InductiveField and ShrinkFactor. The lowering -path exists (SubValueRelation → CallPattern → LoweringTarget). The -lattice operations exist (`merge_argument_relations`, -`sub_value_to_evidence`). - -**The problem is not missing types — it's that these facts are -computed too late (CX-L2 reconstruction) instead of at binding time.** - -The fix: put SubValueRelation on TypeBinding so the existing -authority is preserved from computation to consumption: - -``` -type TypeBinding { - name: String - resolved: Node - provenance: SubValueRelation // NEW — reuses existing authority -} -``` - -No new type algebra. No parallel vocabulary. The same SubValueRelation -that CX-L2 currently reconstructs is instead computed once at binding -time and carried through the IR. - -**Why "at binding time" works:** Inference processes bindings -top-to-bottom (sequential). When `let child = node.left` is bound, -`node` is already in scope with its provenance (`PreservedValue` for -a parameter). The compiler looks up `node`'s binding, finds its -SubValueRelation, and composes with the field access to get `child`'s -provenance. Each binding reads prior bindings' provenance from scope. -The chain is sequential, not circular. - -This is the same computation that `annotate_descent` does today via -`sub_value_vars` — but as a separate reconstruction pass. Under -Option B, the computation happens at binding sites because the scope -already carries provenance. The reconstruction pass dissolves; the -classification logic moves to binding sites (~200 lines). - -**Known gap: SubValueRelation needs extension.** The current type -covers structural descent, iterated elements, and arithmetic descent. -It does NOT cover property contractions (e.g., -`with_required_cardinality` changes a semantic property without -shrinking the value). A `PropertyContraction { domain_size: Int }` -variant is needed. This is a small extension (~5 lines in -std/induction.dag) but should not be deferred. - -**Known limitation: lambda parameters.** Lambda parameter provenance -depends on the call site, not the definition site. When -`f(texpr, callback: child => ...)` is inferred, the lambda param -`child` has no provenance at binding time — its provenance comes from -what `f` does with `callback`, which requires a callee contract. -Collection methods (fold/map/filter) can get contracts via -AlgebraMethodSemantics. User-defined higher-order functions start at -`SubValueUnknown`. **~105 lambda transparency violations will NOT -dissolve in the first iteration.** This is deferred, not solved. - -**What dissolves:** - -| Current reconstruction | Why it dissolves | -|------------------------|------------------| -| `classify_argument` (13 heuristics) | Read `provenance` from binding | -| `classify_let_value` (5 heuristics) | Provenance set at let-bind time | -| `classify_collection_shrink` | Method semantics carry shrink info | -| `build_call_evidence` name matching | Provenance flows with value, not name | -| Lambda transparency guessing | Lambda params inherit provenance from caller | -| `is_child_accessor_in_model` table | Field access sets provenance from type | -| `function_size_effects` table | Function return facts from structural contracts | -| `sub_value_vars` map threading | Provenance IS the binding, not a side map | -| `size_aliases` map threading | Arithmetic provenance tracks factors | -| SCC evidence re-derivation | Read annotated provenance from call args | - -**Pros:** -- Single authority. Reuses SubValueRelation — no dual representation. -- No reconstruction. Facts preserved from computation to consumption. -- Aligns with how the compiler already handles types (types flow - through bindings; SubValueRelation would too). -- Incremental: can be added to TypeBinding without rewriting the - rest of the pipeline. -- Generalizes: the same provenance field serves CX, space analysis, - effect tracking, tracing. -- Preserves recursive syntax as user writes it (no desugaring). - -**Cons:** -- Every binding-creation site must compute SubValueRelation (there - are ~10 sites in 04_infer.dag). -- SubValueRelation must compose through control flow (if/match/block) - — requires worst-case merging (lattice already exists). -- Lambda parameters need special handling: their provenance depends - on the call site, not the definition site. -- Cross-call provenance requires knowing the callee's structural - contract (which parameter the return value derives from). - -**Key design question for Option B:** Lambda parameter provenance. - -When `f(texpr: texpr, callback: child => self(texpr: child))` is -called, the lambda param `child` should carry -`SubValueOf(texpr, field: children)`. But this provenance comes from -what `f` does internally — it iterates over `texpr.children` and -passes each to `callback`. - -Two sub-options: -1. **Callee contracts:** Functions declare what they pass to callback - parameters. `f` declares: "callback receives iterated elements of - param `texpr`." The compiler checks the contract at definition - time and applies it at call sites. -2. **Inline lambda bodies:** Since all lambdas are statically known, - the compiler can inline the lambda at the call site and propagate - provenance through the body directly. - -Sub-option 1 is more modular (works for any higher-order function). -Sub-option 2 is simpler but doesn't generalize to separate -compilation. - -### Decision framework - -Option B is preferred because it preserves the user's syntax, -generalizes to other cross-cutting properties, and aligns with the -compiler's existing binding model. - -If Option B proves unviable (e.g., lambda provenance composition is -too complex to get right), Option A is the fallback — it eliminates -the same anti-pattern by moving classification to a single early pass -rather than reconstructing it later. - -**Option A is a named limitation, not a competing architecture.** -Option A and Option B solve the same classification problem — "what -is this value's structural relationship to the function's inputs?" -The difference is where the answer lives: - -- Option A: in the desugared primitive (the primitive IS the answer) -- Option B: in the binding's SubValueRelation (existing authority) - -The limiting factor for Option A is: **TypeBinding doesn't carry -provenance.** That's the one structural gap. Option A works around it -by classifying at a boundary (desugar pass) instead of at each -binding site. If TypeBinding is ever extended with provenance, the -desugar pass dissolves — the information is already on the bindings, -so there's nothing left to desugar. Option A is a stepping stone -toward Option B, not a fork. - -**The non-negotiable:** the construct-discard-reconstruct pattern -must be eliminated regardless of which option is chosen.

Category G (44) traces to -**arithmetic opacity** — composite expressions like `(n-d)/10` aren't -recognized as ProportionalShrink.

Done. -``` - ---- - -## Option B implementation plan - -### Key insight: SubValueRelation IS provenance - -`SubValueRelation` (std/induction.dag) already models the right -vocabulary: StrictSubValue, IteratedSubValue, ArithmeticDescent, -PreservedValue, SubValueUnknown. It carries InductiveField and -ShrinkFactor. No new type needed — the authority already exists. - -The only thing missing is **placement**: SubValueRelation is -currently computed as a separate reconstruction pass (CX-L2) instead -of at binding time. Put it on TypeBinding: - -``` -type TypeBinding { - name: String - resolved: Node - provenance: SubValueRelation // NEW — reuses existing authority -} -``` - -Source tracking (which parameter this binding derives from) follows -from the scope chain: when `let child = node.left` is bound, the -compiler looks up `node` in scope, finds its SubValueRelation -(PreservedValue for a parameter), and computes `child`'s relation -relative to the same root. No separate `source_param` field needed — -the provenance chain is implicit in the binding structure, just as -type chains are implicit today. - -This reuses the existing type, its lattice operations -(`merge_argument_relations`, `sub_value_to_evidence`), and its -lowering path (direct SubValueRelation → LoweringTarget, bypassing -the lossy CallPattern bridge). No new parallel type system. - -### Binding-site audit: what each site produces - -There are 7 binding-creation sites in `04_infer.dag` that matter -for function-body provenance. Type environment setup (~15 more sites -at lines 3684-3923) creates bindings for type names — these are -always `SubValueUnknown` (type names have no descent relation to -function inputs) and can be ignored. - -**Site 1: Function parameters** (`build_params_scope`, line 699) - -``` -TypeBinding { name: p, resolved: type_expr, provenance: PreservedValue, } -``` - -Parameters are themselves. `PreservedValue` is correct — the -parameter IS the input. This is the root of the provenance chain. - -Available: param name, param type, param index. -Change: add `provenance: PreservedValue`. - -**Site 2: Let-bindings** (`extend_scope`, line 1676) - -The full typed value expression `val_typed` is available. Provenance -is determined by the value expression's structure: - -| Value expression | Provenance | -|------------------|-----------| -| `ExprVar` matching a param | `PreservedValue` (inherited from param binding) | -| `ExprVar` matching a local | inherited from local's binding | -| `base.field` where base has provenance | `StrictSubValue { field, factor: UnitShrink }` | -| `param - k` (arithmetic) | `ArithmeticDescent { factor: ConstantShrink(k) }` | -| `param / k` (arithmetic) | `ArithmeticDescent { factor: ProportionalShrink(k) }` | -| `list \|> skip(k)` | `StrictSubValue { field, factor: ConstantShrink(k) }` | -| `list \|> take(mid)` with DividedSize | `StrictSubValue { field, factor: ProportionalShrink(d) }` | -| Constructor / literal | `SubValueUnknown` (new value, no descent) | -| Function call (unknown contract) | `SubValueUnknown` (fail-closed) | - -Available: `val_typed` (full inferred expression), scope with all -prior bindings and their provenance. -Change: compute provenance from `val_typed` before calling -`extend_scope`. This is the same classification that -`classify_let_value` (line 2413) currently does in CX-L2 — but done -once, at binding time, with the result stored. - -**Site 3: Match arm bindings** (`extend_scope_match_bound`, line 788) - -``` -TypeBinding { - name: field_name, - resolved: field_type, - provenance: StrictSubValue { field: inductive_field, factor: UnitShrink } -} -``` - -Available: variant name (`vname`, line 776), field name -(`field_binding_name_at`, line 782), field type, parent enum, -scrutinee expression. The scrutinee's binding has provenance — -propagate it. -Change: look up scrutinee's provenance from scope, compose with -field access to get variant field's provenance. - -**Site 4: Lambda params with Callable expected** (line 1792-1796) - -``` -TypeBinding { - name: param_name, - resolved: callable_param_type, - provenance: -} -``` - -This is the hard case (see Lambda provenance section below). -Available: expected Callable type with param types. What's NOT -available: which input parameter this lambda param corresponds to. -Change: requires callee contracts or lambda inlining. - -**Site 5: Lambda params with element expected** (line 1798-1812) - -``` -TypeBinding { - name: param_name, - resolved: element_type, - provenance: IteratedSubValue { field: collection_inductive_field } -} -``` - -Available: expected element type, the collection being iterated -(it's the method receiver — available from the call context). -Change: thread the collection's provenance from the method call -context to the lambda param binding. - -**Site 6: Lambda params with no expected** (line 742-755) - -``` -TypeBinding { name: p, resolved: type_variable, provenance: SubValueUnknown } -``` - -Fail-closed: if there's no type context, there's no provenance -context either. `SubValueUnknown` is honest. - -**Site 7: For-each variable** (line 1925) - -``` -TypeBinding { - name: variable, - resolved: elem_type_node, - provenance: IteratedSubValue { field: collection_inductive_field } -} -``` - -Available: `coll_typed` (inferred collection expression), element -type. The collection expression has a binding with provenance. -Change: look up collection's provenance from scope, create -`IteratedSubValue`. - -### Provenance composition algebra - -Provenance composes through control flow. The merge operation already -exists: `merge_argument_relations` (04_infer.dag:2611). The rules: - -**Let-chain (sequential):** -``` -let a = node.left → a: StrictSubValue(node, left) -let b = a.children → b: StrictSubValue(node, left.children) // transitive -``` -Implementation: when computing b's provenance, look up a's -provenance from scope. If a is `StrictSubValue` of some source, -and b accesses a field of a, b is `StrictSubValue` of the same -source (deeper descent). - -**If/match (branching):** -``` -let x = if cond { a.left } else { b } -→ merge(StrictSubValue(a, left), PreservedValue(b)) -→ PreservedValue (conservative — weakest branch wins) -``` -Implementation: compute provenance for each branch, merge via -lattice. This is what `merge_argument_relations` already does. - -**Block (sequential):** -``` -{ let tmp = f(x); tmp.field } -→ provenance of last expression in block -``` -Implementation: provenance of a block is provenance of its last -expression. - -**Lattice order (from strongest to weakest):** -``` -StrictSubValue > IteratedSubValue > ArithmeticDescent > PreservedValue > SubValueUnknown -``` -Merge always takes the weaker (more conservative) of two provenances. -`SubValueUnknown` is absorbing — any branch producing Unknown makes -the whole thing Unknown. - -### Lambda provenance: the hard case - -When `f(texpr: texpr, callback: child => self(texpr: child))` is -called, the lambda param `child` should carry provenance tracing -back to `texpr`. Two approaches: - -**Approach 1: Callee contracts (recommended)** - -Higher-order functions declare what they pass to callbacks: - -``` -// Structural contract in std/ (extends AlgebraMethodSemantics): -type CallbackContract { - callback_param_index: Int // which param is the callback (e.g., 2 for fold's f) - source_param_index: Int // which param is the collection (e.g., 0 for fold's xs) - relation: SubValueRelation // IteratedSubValue for fold/map/filter -} -``` - -Collection methods already have algebra semantics -(`AlgebraMethodSemantics`). Extend with callback contracts: -- `fold(collection, init, f)`: f's element param gets - `IteratedSubValue` of collection -- `map(collection, f)`: f's param gets `IteratedSubValue` -- `descend(tree, f)`: f's node param gets `StrictSubValue` of tree - -For user-defined higher-order functions (e.g., `emit_shared_expr`): -the compiler can INFER the contract by analyzing what the function -does with its callback parameter. In a decidable language, this -analysis terminates. The contract is computed once at definition -time and attached to the function's signature. - -**Approach 2: Lambda inlining (simpler, less modular)** - -Since all lambdas are statically known, inline the lambda body at -the call site and propagate provenance through the body directly. -This avoids contracts but doesn't work for separate compilation. - -**Recommendation:** Start with contracts for collection methods -(these are the common case and already have algebra semantics). -Defer user-defined higher-order function contracts — use -`SubValueUnknown` for those call sites initially. The ~105 lambda -transparency violations are dominated by collection methods; the -user-defined cases are the long tail. - -### ShrinkFactor preservation - -The current pipeline loses ShrinkFactor at `sub_value_to_call_pattern` -(std/induction.dag:208). The fix: **bypass CallPattern entirely.** - -SubValueRelation already carries ShrinkFactor. LoweringTarget needs -ShrinkFactor for the Master theorem. The bridge through CallPattern -is lossy and unnecessary. - -New lowering path: -``` -SubValueRelation → LoweringTarget (direct, preserving ShrinkFactor) -``` - -Instead of: -``` -SubValueRelation → CallPattern → LoweringTarget (lossy bridge) -``` - -This means adding a new function `sub_value_to_lowering_target` in -std/induction.dag that maps directly: - -| SubValueRelation | LoweringTarget | -|------------------|---------------| -| StrictSubValue { field, UnitShrink } | Descend, TreeSize, Strict | -| StrictSubValue { field, ProportionalShrink(d) } | Descend, TreeSize, Strict + factor d | -| IteratedSubValue { field } | Fold, CollectionSize, Strict | -| ArithmeticDescent { param, ConstantShrink(k) } | Repeat, ArithmeticParam, Strict | -| ArithmeticDescent { param, ProportionalShrink(d) } | Repeat, ArithmeticParam, Strict + factor d | -| PreservedValue | Repeat, Forever, NonIncreasing | -| SubValueUnknown | fail-closed: hard error | - -The factor reaches LoweringTarget, so `derive_bound` / -`master_theorem` can compute O(log n) vs O(n) correctly. - -### Final-state CX consumer - -Under Option B, the complexity consumer becomes: - -``` -fn bound_for_recursive_function(entry: FuncEntry) -> CostBound { - let self_calls = find_self_calls(body: entry.body, fn_name: entry.name) - // Each self-call's arguments already carry SubValueRelation from - // inference (on ExprCall.descent_evidence). The difference from today: - // inference computes this at expression-typing time, not as a - // separate reconstruction pass. Call arguments are expressions, - // not bindings — the provenance is on the expression node, not - // looked up from a scope. - let per_call_provenance = self_calls |> map(call => - call.descent_evidence // already on ExprCall, computed during inference - ) - // All self-calls must have Strict on at least one param - let all_have_strict = per_call_provenance |> all(call_ev => - call_ev |> any(p => is_strict(p)) - ) - if all_have_strict { - let best_evidence = select_best_evidence(per_call_provenance) - let target = sub_value_to_lowering_target(best_evidence) - bounded_cost(target, per_iter: cost_of_body(entry.body)) - } else { - CostUnknown { reason: "..." } - } -} -``` - -**What dissolves:** - -| Current code | Lines | Status | -|-------------|-------|--------| -| `annotate_descent_evidence` walk + threading | ~400 | Dissolves — walk is the reconstruction pass | -| `classify_argument` (13 heuristics) | ~200 | **Moves** to binding sites (~200 lines, same logic, different location) | -| `classify_let_value` (5 heuristics) | ~170 | **Moves** to let-binding site (subset of classify_argument) | -| `classify_collection_shrink` | ~90 | Dissolves — method semantics carry shrink | -| `build_call_evidence` | ~30 | Dissolves — read argument provenance | -| `annotate_descent` lambda heuristic | ~50 | Partially dissolves (collection methods via contracts; HOFs deferred) | -| `is_child_accessor_in_model` table | ~10 | Dissolves — type-derived | -| `function_size_effects` table | ~40 | Dissolves — structural contracts in std/ | -| `construct_termination_proof` (old system) | ~200 | Dissolves — single authority | -| `classify_scc_call_progress` | ~60 | Dissolves — read annotated provenance | -| `sub_value_to_call_pattern` (lossy bridge) | ~15 | Dissolves — direct lowering | -| Thread-through maps (param_names, sub_value_vars, size_aliases) | ~100 | Dissolves — provenance on binding | -| **Total reconstruction code** | **~1365** | | - -**Honest accounting:** ~200 lines of classification logic (the core -of `classify_argument` and `classify_let_value`) moves to binding -sites — the same computation, done earlier.

Default to `SubValueUnknown` at all creation sites. - This is a no-op change — all existing behavior preserved, all tests - pass. - -2. **Instrument one site at a time.** Starting with the easiest - (function parameters → `PreservedValue`), update each binding site - to compute provenance. After each site, the downstream CX code can - optionally READ provenance instead of reconstructing — but doesn't - have to yet. - -3. **Add direct lowering.** Write `sub_value_to_lowering_target` in - std/induction.dag. This preserves ShrinkFactor. - -4. **Switch CX to read provenance.** Replace `classify_recursion_pattern` - to read `binding.provenance` from self-call arguments instead of - calling `collect_self_call_evidence` → `classify_argument`. This - is the switchover point. - -5. **Delete reconstruction code.** Once CX reads provenance, the - entire `annotate_descent_evidence` pass and its 33 heuristic - functions can be deleted. The hardcoded tables dissolve. - -Steps 1-2 can run in parallel with existing CX code (provenance is -computed but not consumed yet). Step 4 is the switchover. Step 5 is -cleanup. - -### Open design questions - -1. **SubValueRelation composition through control flow.** The - conservative merge (weakest branch wins) may be too aggressive — a - function that returns `a.left` in one branch and `a.right` in - another should still be `StrictSubValue`, not `PreservedValue`. The - merge should check: are both branches sub-values of the same - source? If so, keep `StrictSubValue` with the weaker factor. - The lattice operation `merge_argument_relations` already exists - (04_infer.dag:2611) — the question is whether it needs refinement. - -2. **Lambda parameter provenance: contracts vs inline.** Callee - contracts are recommended for collection methods (already have - algebra semantics via AlgebraMethodSemantics). User-defined - higher-order functions deferred to `SubValueUnknown` initially. - The decidability invariant guarantees inlining is always possible - as a future fallback. - -3. **Function return contracts.** For cross-call provenance (function - f calls accessor g), g needs a structural contract declaring the - relationship between its return value and its parameters. This is - a .dag structural fact (like AlgebraMethodSemantics), not an - annotation. E.g., `param_node_type_expr` would carry a structural - witness in std/ declaring "return is SubValueOf(param 0)." This - dissolves `is_child_accessor_in_model`. Deferred until the basic - binding-level provenance pipeline is working. - ---- - -## Cross-compiler audit: the anti-pattern is systemic - -The construct-discard-reconstruct pattern is not CX-specific. An -audit of all compiler stages found the same structural gap in every -stage that needs facts about values beyond their types. - -### Confirmed instances - -**1. Complexity (CX) — 33 reconstruction heuristics** - -Fully documented above. TypeBinding drops provenance. CX-L2 -reconstructs via string matching, accessor tables, and AST re-walks. -424 violations. ~1100-1200 lines net dissolution (~200 lines of -classification logic moves to binding sites). - -**2. Ownership — string name matching for fold accumulators** - -`ownership.dag` re-derives fold structure by name-matching: -- `a.name == "init"` to find fold initializers (line 214) -- `terminal.name == acc_type_name` to identify accumulator structs - (line 430) -- `collect_acc_field_moves` re-walks the body to find field accesses - (lines 438-454) - -Root cause: inference knows the fold structure (which arg is init, -which is body, which is collection) but stores it as generic ExprCall -children with string names. Ownership must reconstruct semantics -from names. - -**3. Emission — upstream information loss (M2)** - -The ROADMAP reviewer root cause analysis (2026-04-03, line 193) -already identified this: "facts that exist upstream are lost before -emit, so emission compensates with heuristics." Specific instances: -- `variant_to_enum` map uses empty string as ambiguity sentinel; - emitter falls back to AST inspection (05_emit_rust.dag:1787) -- Emitter re-derives method dispatch, expression semantics, and - clone decisions that inference already computed - -M2 (Boundary Sufficiency) is the same anti-pattern named differently: -the resolution→emit boundary doesn't carry enough structure. - -**4. Core tables — hand-maintained semantic maps** - -`00_core.dag` maintains hardcoded tables that should be derived from -type declarations: -- `expr_child_roles` (line 750): maps ExprData variant names to - their child accessor functions — via string keys -- `node_field_roles` (line 845): maps Node field names to structural - recursion roles — via string keys -- `function_size_effects` (line 881): maps function names to size - effects (TreeSizePreserving, TreeSizeReducing) — via string keys - -Every consumer that queries these tables is doing name-based -reconstruction of facts that the type system already has. - -**5. Inference — string dispatch for built-in functions** - -`04_infer.dag` has `if func_name == "..."` branches for built-in -function type logic: -- `func_name == "empty_map"` (line 1228) -- `func_name == "map_get"` (line 1256) -- `func_name == "map_keys"` (line 1269) -- `func_name == "map_values"` (line 1282) - -Each branch applies type-narrowing rules that should be declared on -the function's signature, not hardcoded as name-matching in the -inference engine. - -**6. Algebra — ExprBinOp.algebra_field: AlgebraFieldKind?** (RESOLVED) - -Resolved: `algebra_field` now uses the structural `AlgebraFieldKind` -coproduct defined in `std/syntax.dag`. All producers and consumers -updated to use structural dispatch instead of string matching. - -### The pattern - -Every instance follows the same structure: - -``` -Stage N computes a structural fact - ↓ -IR stores only the type (or a string proxy) - ↓ -Stage N+k reconstructs the fact via name matching / AST re-walking -``` - -The root cause is always the same: **the IR vocabulary is too narrow.** -TypeBinding stores `{ name, resolved }`. ExprCall stores generic -children. ExprBinOp stores a string. Each narrowing forces downstream -stages to reconstruct what upstream stages already knew. - -### What provenance-on-bindings fixes (and what it doesn't) - -Provenance on TypeBinding directly fixes instances 1 (CX) and 2 -(Ownership). It indirectly helps with 3 (Emission) by making value -relationships visible to emit. - -Instances 4-6 are separate but related: they're about semantic -metadata on types and operations (not on bindings). The fix for -those is to move hand-maintained tables into type declarations in -std/ — the same "declare facts at authority" principle. - -All six instances share one thesis: **the IR should carry structural -facts from the point of computation to the point of consumption.** -Provenance on bindings is the first and highest-leverage fix. -Type-derived semantic tables are the second. - ---- - -## Workboard - -Active work items.

Single dimension, field on TypeBinding. - -### Phase 2: Ownership on bindings - -Add OwnershipKind to TypeBinding (or external table). Compute -at binding sites during inference. Dissolve the separate -ownership pass. SharedError becomes a gate check on the -dimension value. - -### Phase 3: Effects - -Declare EffectLevel in std/behavioral.dag with lattice. Compute -at binding sites (function calls mark effectful, pure code stays -pure). Carry through bindings.

TypeBinding carries -a dimension table (or external tables keyed by binding ID). -The compiler discovers dimensions from std/ declarations.

No compiler changes needed. - ---- - -## Design questions (open) - -1. **Binding identity.** Tables keyed by binding identity need - stable IDs. Currently bindings are identified by string name. - InternTable (Track 3, PR #367) provides `ident: Int` but it's - not wired through TypeBinding yet. This is a prerequisite for - Option B (external tables). - -2. **Dimension interaction.** Are dimensions truly orthogonal, or - do some interact? Example: provenance and ownership interact — - if a binding is StrictSubValue (provenance) and the sub-value - is the only consumer (ownership), the compiler can move instead - of clone. The interaction is at the enforcement level, not the - carrying level — each dimension is computed independently, but - enforcement can read multiple dimensions. - -3. **Performance.** Each dimension adds O(1) work per binding site. - With N dimensions, total overhead is O(N × bindings). For - built-in dimensions (3-5), this is negligible. For user-defined - dimensions, need to verify that the lattice operations are - bounded (they are, in a closed system — all lattices are finite). - -4. **Composition rule expressiveness.** The current composition - rules (field access, iteration, arithmetic, construction) are - sufficient for provenance and ownership.

The fold structure (which arg is init, -which is body, which is collection) was known at inference time. - -**2.

Field move collection by AST re-walk** (lines 438-454) - -``` -fn collect_acc_field_moves(...) -> List { - // re-walks body to find acc.field accesses -``` - -Reconstruction: re-walks the entire fold body looking for field -accesses on the accumulator variable.

The ownership-internal span_start data is correct, -but cannot be exposed at the emit boundary until bindings have unique -identifiers. - -**Blocked on:** Track 3 (stable binding identity via InternTable or -declaration span).

The branch-aware merge in ownership analysis -already computes correct fan-out for TCO functions: - -- Parameters only threaded through self-calls (not used in body) - already have fan-out=1 and ARE movable. No V2 violation. -- Parameters used in body AND self-call genuinely have fan-out>=2. - The clone is needed because Rust's loop semantics require the - value for both the body use and the next-iteration use. - -**Done:** TCO identity pass-through elision in the emitter (PR TBD). -Self-calls like `f(tokens: tokens, state: new_state)` now skip the -`tokens = tokens` reassignment, reducing generated code size.

Instead of a separate `s` variable -for advanced state, **shadow `tokens` at each consumption step**: - -```dag -// Before: tokens is FULL list, state.pos tracks position, s rebinds state -let s = skip_newlines(tokens: tokens, state: state) -let r = expect(tokens: tokens, state: s, expected: ExpectKeyword { text: "module" }) -if has_err(err: r.err) { return ModuleResult { ..., state: r.state, err: r.err } } -let s = r.state -let r = parse_dotted_ident(tokens: tokens, state: s) - -// After: tokens IS the remaining list, shadowed at each step -let tokens = skip_newlines(tokens: tokens) -let tok = tokens |> first // inspect current token -let r = expect(tokens: tokens, expected: ExpectKeyword { text: "module" }) -if has_err(err: r.err) { return ModuleResult { ..., tokens: r.tokens, ctx: ctx, err: r.err } } -let tokens = r.tokens // shadow: tokens is now after expect -let r = parse_dotted_ident(tokens: tokens, ctx: ctx) -let tokens = r.tokens // shadow: tokens is now after dotted_ident -``` - -**Key invariant:** `tokens` always means "current remaining." No `s`, -`s2`, or `s3` variables. Inspection uses `tokens |> first` (unambiguous). -Error returns use `ctx` from scope (not `r.ctx`), since helper results -don't carry ctx. - -**Why this works:** In the old code, `tokens: tokens` in every call was -correct because `tokens` was the unchanging full list.

No integer offset reasoning. - -### D7: Tokenizer deferred (separate PR) - -The tokenizer (`01_tokenize.dag`) has the same integer-opacity pattern -(`pos: Int` on `source_chars: List`), accounting for 22 violations. -However, the tokenizer **constructs spans from byte positions** -(`make_span(start: pos, end: pos + len)`). Restructuring to list -consumption requires designing how to track byte offsets for span -construction without reintroducing integer position tracking.

Each level subsumes the one -below — if Level 4 passes, Levels 0-3 are implied. - -### Level 0: Data declaration correctness - -**What:** Structural tests auto-generated from data declarations. -Every data declaration carries a testable claim about the system's behavior. - -**How:** The compiler iterates over data tables (TypeCheckpoint, -InhabitantDecl, AlgebraFieldTemplate, etc.) and generates assertions -that the lookup functions return the declared values. Adding a new -data entry auto-generates a new test. - -**Current state:** Implemented for coercion data. `extract_coercion_tests()` -in `coercion.dag` reads `target_checkpoints()` / `target_inhabitants()` and -produces `CoercionTestEntry` values. `compiler_tests_rust.dag` renders these -to Rust test functions. 24 checkpoint assertions + container + copy + template -tests, all derived from `dsl/extdeps/languages/*/types.dag`. - -**Concept types:** `std/verification.dag` (AssertKind, TestClaim, TestCase), -`CoercionAssertion` / `CoercionTestEntry` in `coercion.dag`. - -**Next candidates:** -- Algebra method semantics (AlgebraMethodSemantics → complexity analyzer tests) -- Keyword/reserved word tables (languages.dag → tokenizer tests) -- Runtime function registry → runtime shim coverage tests -- Container-to-algebra mapping → type resolution tests - -### Level 1: Function correctness - -**What:** Each compiler function produces correct output for known inputs. -Unit and integration tests that call pipeline functions directly. - -**Current state:** 358 enabled tests in `v2-compiler-tests` crate. -Pipeline tests (226), source audits (37), parse tests (43), inference -semantics (34), diagnostics (11), bootstrap (7). Tests call stage0 -functions directly — no subprocess overhead. - -**Infrastructure:** `helpers.rs` provides `compile_dag()`, -`compile_dag_target()`, `compile_multi()`, `diagnostic_messages()`, -`assert_no_diagnostics()`, `find_file()`. FF-9 import resolution -via `build_module_index()` + `resolve_imports_transitively()`. - -**Gap:** These tests are hand-written Rust. Many test the same patterns -that Level 0 could auto-generate. As structural test generation matures, -hand-written tests should shrink to only the cases that can't be derived -from data. - -### Level 2: Bootstrap correctness - -**What:** The compiler can process its own source. Self-hosting proof. - -**Current state:** 7 bootstrap tests (mostly `#[ignore]` — expensive). -- `strict_compile_diagnostic_count`: 0 diagnostics (ratchet) -- `bootstrap_stage0_to_stage1`: emitted Rust cargo-checks (0 errors) -- `bootstrap_fixed_point`: stage1 == stage2 (idempotence) -- `performance_ratchet`: ~4.8s compile time (30s budget) -- Stage0 freshness gate: `regenerate → diff → empty` - -**Infrastructure:** `regenerate-stage0.sh`, `check-stage0-freshness.sh`. -All stage0 files fully generated (0 hand-maintained). Bootstrap D complete. - -**Self-test:** The compiler's own test suite (`compiler_tests.rs`) is -generated by the emitter. When the compiler self-compiles, it produces -its own tests — including Level 0 structural tests from its own data -declarations. The compiler tests itself using the same framework it -provides to user code. - -### Level 3: Syntax validity - -**What:** Emitted code is syntactically valid in the target language. - -**Current state:** -- Rust: `cargo check` on stage1 (0 errors) -- Python: `python3 -c "import ast; ast.parse(...)"` on emitted files -- Go: structural checks (package, import, func Test, testing.T) - -**What this proves:** The emitter produces parseable target-language code. -What it doesn't prove: the code does the right thing when run. - -### Level 4: Semantic correctness - -**What:** Emitted code runs and produces correct results. - -**Witnesses provide the inputs. Oracles check the outputs.** Five -oracles, all but the last derived from structure: - -| Oracle | What it checks | Witness layer | Hand-written? | -|---|---|---|---| -| Type membership | Output inhabits return type | L1 (canonical) | No — compiler proves statically | -| Constraint satisfaction | Output passes `where` predicates | L4 (boundary) | No — predicate IS the oracle | -| Algebraic laws | Operations satisfy declared laws | L3 (algebra) | No — laws declared on algebra | -| Cross-target agreement | Same input → same output | All layers | No — differential comparison | -| Known values | Specific input → specific output | L5 (samples) | Sometimes | - -**Example:** `filter([0, 1, 2, 3], x > 1)` with FreeMonoid algebra: -- Type membership: output is `List` ✓ -- Constraint: every output element satisfies `x > 1` ✓ (predicate oracle) -- Algebraic: `output.count <= input.count` ✓ (filter never grows) -- Cross-target: Rust and Python both produce `[2, 3]` ✓ -- Known value: `[2, 3]` — but Layers 1-3 already prove correctness - -**Current state:** Almost nothing. Only bootstrap fixed-point indirectly -executes emitted code. No tests run emitted Rust/Python/Go with inputs -and check outputs. - -**What's needed:** -- Witness generation from type structure (Layers 1-5 above) -- Oracle evaluation: run emitted code, apply structural checks -- Service DryRun: exercise operations with mock_response witnesses -- Cross-target differential: same .dag → multiple targets → compare - -### Level 5: Cross-language equivalence - -**What:** Same `.dag` source → equivalent behavior in Rust, Python, Go. - -**Current state:** Nothing. Each target is tested in isolation. No -differential tests. - -**How:** Compile the same `.dag` to all targets. Run each with the same -inputs. Assert outputs match (or are equivalent modulo representation). -The test oracle is structural: if both targets inhabit the same algebra, -their behavior under that algebra's laws must agree. - -### Level 6: Exhaustive form coverage - -**What:** Every structural form the language can express compiles correctly. - -**How:** The .dag input language is decidable and Node-bounded, so the -space of structural forms reaching the emitter is finite. The emission -algebra is `(NodeKind × TypeForm × Cardinality)` — enumerable from the -.dag type definitions. A test generator synthesizes one minimal `.dag` -program per element and compiles it to every target. - -**Current state:** Nothing. `full_dsl_compiles` tests that existing .dag -files compile, but doesn't systematically cover the form space. - -**What this proves:** Emission is total. No `compile_error!` or -`TODO` paths reachable by valid .dag input. New forms added to the -language automatically produce new test cases. - -### Level 7: Performance contracts - -**What:** Compile time, memory, operation counts stay within bounds. - -**Current state:** Minimal. -- `performance_ratchet`: 30s budget, ~4.8s actual -- Individual tests >2s are suspect (project convention) -- Per-module reconcile profiling (RSS checkpoints, ignored) - -**What's needed:** Operation-count contracts (node visits, inference passes, -emit calls). More deterministic than wall-clock, catches algorithmic -regressions independent of machine load. - ---- - -## Witness generation: layered, structural - -A **witness** is a concrete value that proves a type is inhabited. -An **oracle** is a structural check that determines whether a function's -output is correct — derived from the type system, not hand-written. - -Witnesses are generated in layers. Each layer adds more witnesses from -deeper structural information. The compiler determines how many witnesses -it needs from the algebra's laws and the type's constraints. - -### Layer 1: Canonical witnesses (type inhabitation) - -One value per type form. Proves the type is constructible. - -| Type pattern | Witness | Derived from | -|---|---|---| -| Leaf (`Int`, `Float`) | `0`, `0.0` | Primitive zero value | -| Leaf (`String`, `Bytes`) | `""`, `[]` | Primitive empty value | -| Leaf (`Bool`) | `false` | Primitive false value | -| Product (all edges) | All fields with child witnesses | Product of constructible = constructible | -| Coproduct (one edge) | First variant with child witness | At least one variant is constructible | -| Optional | present(witness) AND absent | Two witnesses per optional | -| Collection | `[]` AND `[witness]` | Empty + one-element | - -Layer 1 proves types exist but doesn't exercise operations meaningfully. -`multiply(0, 0)` is always 0 — doesn't catch multiplication bugs. - -### Layer 2: Variant witnesses (coproduct exhaustiveness) - -One witness per variant of every sum type. Exhaustive. - -| Type | Witnesses | What it exercises | -|---|---|---| -| `Bool` | `true`, `false` | Both values (exhaustive — Bool has cardinality 2) | -| `Shape = Circle \| Rect` | `Circle { r: 0.0 }`, `Rect { w: 0.0, h: 0.0 }` | Both code paths | -| `Result` | `Ok(witness_T)`, `Err(witness_E)` | Success and failure paths | - -**Cardinality coverage falls out of structure.** A type with N optional -fields has 2^N cardinality combinations. The compiler generates witnesses -for all valid combinations (respecting cross-field constraints). - -### Layer 3: Algebra-derived witnesses (law exercise) - -The algebra declares special elements. These determine WHICH values are -interesting for operations. The compiler reads the algebra declaration -and derives the minimum witness set needed to exercise its laws. - -| Algebra | Special elements | Witnesses | Laws exercised | -|---|---|---|---| -| Monoid | identity | `e`, `a`, `b` | `op(e, a) == a`, `op(op(a,b),c) == op(a,op(b,c))` | -| Ring | zero, one | `0`, `1`, `-1`, `2`, `3` | `add(0,x)==x`, `mul(1,x)==x`, `mul(2,3)==6` | -| FreeMonoid | empty | `[]`, `[a]`, `[a,b]` | `concat([],xs)==xs`, `filter` preserves predicate | -| BooleanAlgebra | empty | `{}`, `{a}`, `{a,b}` | `union({},s)==s`, `intersect` commutes | - -**Why this matters for thoroughness:** a binary operation needs at least -3 witnesses (identity + two non-identity values). With only `0`, you'd -never exercise `multiply(2, 3) == 6`. The algebra's laws tell the compiler -exactly how many distinct witnesses it needs and what roles they play. - -The special elements (identity, zero, one) come from the algebra -declarations in `std/algebra.dag`. The non-trivial witnesses (`2`, `3`) -come from "the smallest non-special inhabitants of the carrier type." - -### Layer 4: Constraint-boundary witnesses (predicate edges) - -If a type has `where` predicates, the boundaries are structurally -interesting: - -```dag -type PositiveInt = Int where > 0 -``` - -Witnesses: `1` (just inside boundary — should pass), `0` (just outside — -should be rejected). The constraint predicate IS the oracle: the compiler -runs the value through the predicate and checks the result. - -For string patterns: `Url = String where pattern("https?://.*")` — the -compiler can generate a value matching the pattern if the pattern is -simple enough, or require a user-provided sample (Layer 5) if not. - -### Layer 5: Compositional samples (user-declared domain knowledge) - -When Layers 1-4 can't produce a structurally valid witness (e.g., a -complex regex, a domain-specific format), the user provides samples: - -```dag -type Url = String where pattern("https?://.*") { - samples: ["https://example.com", "https://api.github.com/repos/owner/repo"] -} -``` - -Samples propagate compositionally — any type using `Url` automatically -gets realistic URLs. `PullRequest { html_url: Url }` gets its `html_url` -from `Url.samples` without the user redeclaring it. - -**The compiler tells you when Layer 5 is needed:** if a type has -constraints that Layers 1-4 can't satisfy, the compiler emits -`under_specified` and requires samples. This is the mechanism that makes -untestable code structurally unrepresentable — you must provide enough -information for the compiler to generate witnesses. - -### Service witness generation - -Services have the richest witness structure because they combine type -witnesses with protocol semantics. A service operation like: - -```dag -service github.Gist { - operation Create { - input { description: String, content: String, public: Bool = false, auth_token: Secret } - output { id: GistId, html_url: Url } - response { 201 => Gist, 401 => ErrorShape, 422 => ErrorShape } - mock_response { - 201 => { id: "gist-abc123", ... } "Created successfully" - 401 => { message: "Bad credentials" } "Invalid auth" - 422 => { message: "Validation Failed" } "Empty files rejected" - } - } -} -``` - -generates witnesses at multiple layers: - -| Layer | Source | Witnesses generated | -|---|---|---| -| L1 (canonical) | Input param types | `{ description: "", content: "", public: false, auth_token: "" }` | -| L2 (variants) | Response status codes | One test per status code (201, 401, 422) | -| L3 (algebra) | Transport classification | DryRun vs Selective vs Full Real tier | -| L4 (constraints) | `GistId = String where format(uuid)` | Valid UUID + invalid UUID | -| L5 (samples) | `mock_response` blocks | Complete response bodies per status code | - -**The `mock_response` block is Layer 5 for services** — user-provided -witness data for each response scenario. The compiler verifies mock -data matches the declared response type (structural oracle). It also -generates the DryRun test (Tier 1) and the integration test artifact -(Tier 3) from the same mock data. - -**Error paths are witnesses too.** Each error response code (401, 422) -is a variant witness — the compiler generates a test that exercises -the error handling path with the mock error response. - -### Scenario mocks (hand-authored, cross-field) - -Only needed when fields have cross-cutting constraints the type structure -alone can't express: "when state is 'open', merged_at should be null." -These supplement compositional mocks, not replace them. - ---- - -## Test generation: what the compiler produces - -The compiler generates test artifacts as part of emission. Tests are -output files alongside application code. - -### Currently implemented - -| Generator | Input | Output | Level | -|---|---|---|---| -| `extract_coercion_tests()` | TypeCheckpoint, InhabitantDecl data | Coercion assertion test functions | L0 | -| `extract_test_projections()` | Service operations with `mock_*` fields | Per-service test functions (DryRun) | L4 (partial) | -| `emit_compiler_tests_module()` | Compiler pipeline (self-compile) | compiler_tests.rs with bootstrap + structural tests | L0-L2 | -| Stage0 freshness gate | .dag source ↔ committed stage0 | Pass/fail (CI blocking) | L2 | -| Per-module test files | TestProjection per module | Rust/Python/Go test files | L4 (partial) | - -### Not yet implemented - -| Generator | Input | Output | Level | -|---|---|---|---| -| Structural witness generator | Type definitions | Canonical witness values per type | L4 | -| Algebraic law tester | `law` declarations on algebra types | Property tests from laws | L4 | -| Constraint oracle | `where` predicates on types | Output validation tests | L4 | -| Cross-target differential | Same .dag + multiple targets | Equivalence assertions | L5 | -| Form space enumerator | .dag type definitions (emission algebra) | One program per structural form | L6 | -| Operation-count contracts | Pipeline stage boundaries | Deterministic perf assertions | L7 | - ---- - -## Execution tiers - -``` -Tier 1 (DryRun) runs during compilation - All transports mocked. - Proves: wiring, types, coercion, structural. - Failure = compile error. - -Tier 2 (Selective) runs during compilation - Hermetic effects only (temp dirs, env vars). - Failure = compile error. - -Tier 3 (Full Real) NOT run during compilation - Requires real credentials, live services. - Compiler GENERATES the test as output artifact. - Receipt marks: "generated-not-run" -``` - -**Classification:** `std/fidelity.dag` defines `TestClass = Unit | Hermetic -| Integration` and `TransportClass`. `classify_transports()` derives the -tier from the transitive transport closure — max transport dominates. - ---- - -## Guarantee receipt - -The compiler emits a JSON receipt — the single authority for what the -compilation proved, tested, and left uncertain.

These - should shrink as Level 0 auto-generation covers more ground. - -3. **Level 2** — Bootstrap tests verify self-hosting: the compiler can - parse, compile, and emit its own source. Fixed-point convergence - proves idempotence. - -4. **Level 3** — Stage0→stage1 cargo check proves emitted Rust is valid. - Python/Go syntax validation proves multi-target correctness. - -When the compiler self-compiles, the emitter produces `compiler_tests.rs` -— which includes Level 0 structural tests generated from its own data -declarations. The compiler is both the test generator and the test subject. - ---- - -## Phased implementation - -Each level becomes a compile-error gate as it's implemented: - -| Phase | What becomes a compile error | Status | -|---|---|---| -| **Done** | Missing service mock for declared hermetic boundary | Working | -| **Done** | Structural test failures from data declarations | Working (coercion) | -| **Next** | Type roundtrip failures (structural witnesses) | Not yet | -| **Next** | Failed algebraic law checks with samples | Not yet | -| **Future** | Cross-target disagreement | Not yet | -| **Future** | Exhaustive form coverage gaps | Not yet | - -The receipt records which levels are active.
