Inference handles 80%, explicit annotations for the rest 20%. | + +### Criterion 4: Recursion Support — Clean recursive type definitions? + +| Candidate | Score | Rationale | +|-----------|-------|-----------| +| A: Annotation | 5 | `Schema.suspend(() => MySchema)` — standard Effect pattern, compiler memoizes via Suspend handler. | +| B: Builder | 4 | `P.lazy(() => LinkedList)` — works but is a thin rename of `Schema.suspend`. No special handling. | +| C: Class | 4 | `Schema.suspend(() => LinkedList)` works in fields. But class-based types can't self-reference as easily as schemas (class must be declared before use). | +| D: Hybrid | 5 | Same as A for annotated schemas. TSchema path already handles recursion via `Schema.suspend`. Both paths tested. | + +### Criterion 5: Compatibility — Works with existing Data.withSchema pipeline? + +| Candidate | Score | Rationale | +|-----------|-------|-----------| +| A: Annotation | 4 | Compiler output is a TSchema-compatible Schema. But it's a NEW derivation — existing TSchema pipelines need to be replaced, not augmented. | +| B: Builder | 5 | Functions return TSchema values directly. `P.codec(x)` = `Data.withSchema(x)`. Zero friction. | +| C: Class | 3 | Classes have their own codec methods (`.toData()`). Doesn't easily compose with `Data.withSchema()`. Need adapter layer for existing code that expects schemas. | +| D: Hybrid | 5 | `Plutus.codec()` wraps `Data.withSchema()`. TSchema values work directly. Both paths produce compatible output. | + +### Criterion 6: Extensibility — Easy to add new patterns later? + +| Candidate | Score | Rationale | +|-----------|-------|-----------| +| A: Annotation | 5 | Add new annotation symbol + handler in Match — open/closed principle. Third-party annotations possible. | +| B: Builder | 3 | Adding patterns means adding functions. Each new pattern = new export. Can't be extended by users without modifying the module. | +| C: Class | 4 | New encoding patterns = new base class. Extensible but heavy — every extension needs a class hierarchy. | +| D: Hybrid | 5 | Annotation path extensible like A. Builder path (variant, option) extensible like B. Users can add custom annotations for new patterns. | + +### Criterion 7: Effect Idiom Alignment — Feels natural in Effect ecosystem? + +| Candidate | Score | Rationale | +|-----------|-------|-----------| +| A: Annotation | 5 | Annotations + AST compiler = exactly how Pretty/Arbitrary/Equivalence work. Core Effect pattern. | +| B: Builder | 2 | Custom DSL that doesn't use Effect's Schema infrastructure. Feels like a separate library that happens to produce schemas. | +| C: Class | 4 | `Schema.Class` is Effect-native. But the Plutus protocol layer is custom. `datum.toData()` is imperative, not Effect-idiomatic (would be Effect pipe). | +| D: Hybrid | 5 | Uses Effect annotations, Schema composition, and derives like other Effect modules. `Plutus.data()` is just a Schema transformation — fully composable. | + +### Criterion 8: Migration from Current TSchema — How easy to adopt? + +| Candidate | Score | Rationale | +|-----------|-------|-----------| +| A: Annotation | 3 | Requires rewriting all TSchema usage to annotated Schema types. Conceptual shift from "combinators" to "annotate + derive". | +| B: Builder | 4 | Similar vocabulary to TSchema — rename `TSchema.Struct` → `P.constr`, etc. Mostly mechanical. | +| C: Class | 2 | Complete rewrite — every type becomes a class. Variant/union types change fundamentally. | +| D: Hybrid | 5 | **Zero migration required.** Existing TSchema code works unchanged. New code can use either path. Gradual adoption. | + +## Score Summary + +| Criterion | Weight | A | B | C | D | +|-----------|--------|---|---|---|---| +| Type safety | 1.0 | 4 | 4 | 5 | 4 | +| Ergonomics | 1.5 | 3 | 4 | 4 | 5 | +| Completeness | 1.5 | 5 | 4 | 3 | 5 | +| Recursion | 1.0 | 5 | 4 | 4 | 5 | +| Compatibility | 1.5 | 4 | 5 | 3 | 5 | +| Extensibility | 1.0 | 5 | 3 | 4 | 5 | +| Effect alignment | 1.0 | 5 | 2 | 4 | 5 | +| Migration | 1.5 | 3 | 4 | 2 | 5 | +| **Weighted Total** | | **39.5** | **37.5** | **33.5** | **48.5** | + +## Decision + +### Winner: Candidate D (Hybrid) + +**Score: 48.5** — highest on every dimension except type safety (where C wins by 1 point on a low-weight criterion). + +**Key reasons**: +1. **Non-breaking migration** — existing codebase untouched, adopt incrementally +2. **Dual-path** — TSchema for power users, `Plutus.data()` for convenience +3. **Type inference** — `Plutus.data(Schema.Struct({...}))` infers encoding automatically +4. **Effect-native** — uses annotations, AST compiler, Schema composition +5. **Complete** — all 33 patterns covered between TSchema and Plutus.data paths + +### Runner-up: Candidate A (Annotation-Driven) + +**Score: 39.5** — strong on extensibility and Effect alignment, but verbose annotations and harder migration hurt it. + +**Incorporate from A into D**: The AST compiler (`Match` + `getCompiler`) is the implementation strategy for D's `Plutus.data()` inference engine.

Plutus Map +`Plutus.data()` does not auto-derive Map encoding from `Schema.Map`. Maps require TSchema.Map: +```typescript +// Won't work: Plutus.data(Schema.Map({ key: ..., value: ... })) +// Use instead: +const MyMap = Plutus.Map(Plutus.ByteArray, Plutus.Integer) +``` +**Why**: Schema.Map uses a Declaration AST node, and the compiler treats unknown Declarations as passthrough. Map encoding requires a specific CBOR map representation that differs from the standard Schema.Map behavior. + +### 2. FlatFields (Nested Struct Inlining) +The `flatFields` annotation is defined but not yet implemented in the compiler. Structs are always encoded as nested Constrs: +```typescript +// Currently: inner struct is always a nested Constr +// flatFields would inline inner fields into parent +``` +**Why**: This is a complex encoding that requires coordinating field counts between parent and child structs during both encoding and decoding. TSchema implements this via string annotations, but the compiler doesn't yet handle it. Use TSchema.Struct with `flatFields: true` for now. + +### 3. Mutual Recursion +Only self-recursion via `Schema.suspend` is supported. Mutual recursion (type A references type B which references type A) is not tested and may not work: +```typescript +// Not supported: +// type Expr = Literal | BinOp +// type BinOp = { left: Expr, right: Expr } +``` +**Why**: The memoizeThunk approach handles single-schema cycles but may not handle cross-schema cycles. This would require a shared memo map across compilations. + +### 4. TypeScript Enums +TS `enum` types (`Schema.Enums`) throw an error. Use `Schema.Literal` instead: +```typescript +// Won't work: enum Color { Red, Green, Blue } +// Use instead: Schema.Literal("Red", "Green", "Blue") +``` + +### 5. String / Number Types +These have no Plutus Data representation and throw descriptive errors.

Key fix: recursive schemas use `Schema.suspend((): Schema.Schema => X)` with explicit encoded type annotation — matches Effect's own test pattern from TSchema.recursive.test.ts. No casts needed. Remaining 2 are intentional wrong-type error tests (`"not a bigint" as any`). 262 tests passing. 11. **Edge case sweep** — 30 new tests across 10 handler categories. All pass without compiler fixes needed. Tested: tag-only structs, all-flat structs, field order, single-member unions, mixed primitive unions, NullOr(union), empty/nested tuples, double-wrapped suspend, all literal types (0n, negative, boolean, number, long string), empty/nested maps, nested flatFields, refinement chains, deeply nested heterogeneous roundtrip, null at every nesting level. No silent wrong output found. 292 total tests passing. 12. **Fix silent passthrough for unknown Declarations** — Declaration handler now throws by default for unrecognized types (following JSON Schema's approach). Added explicit detection: Set/HashSet/ReadonlySet→Set (CBOR list, decoded back to Set), List/Chunk→Array (CBOR list), HashMap/ReadonlyMap→Map (already handled). Date, Duration, FiberId, OptionFromSelf, SortedSet, custom Schema.declare all throw with descriptive error including path. 8 new tests (Set encode/decode, empty Set, ReadonlyMap, DateFromSelf/DurationFromSelf/OptionFromSelf throw, error path). 300 total tests passing. +13. **Benchmark improvements** — Comprehensive benchmark suite with proper warmup (5000 iterations each).

Tested: tag-only structs, all-flat structs, field order, single-member unions, mixed primitive unions, NullOr(union), empty/nested tuples, double-wrapped suspend, all literal types (0n, negative, boolean, number, long string), empty/nested maps, nested flatFields, refinement chains, deeply nested heterogeneous roundtrip, null at every nesting level. No silent wrong output found. 292 total tests passing. 12. **Fix silent passthrough for unknown Declarations** — Declaration handler now throws by default for unrecognized types (following JSON Schema's approach). Added explicit detection: Set/HashSet/ReadonlySet→Set (CBOR list, decoded back to Set), List/Chunk→Array (CBOR list), HashMap/ReadonlyMap→Map (already handled). Date, Duration, FiberId, OptionFromSelf, SortedSet, custom Schema.declare all throw with descriptive error including path. 8 new tests (Set encode/decode, empty Set, ReadonlyMap, DateFromSelf/DurationFromSelf/OptionFromSelf throw, error path). 300 total tests passing. 13. **Benchmark improvements** — Comprehensive benchmark suite with proper warmup (5000 iterations each).

The codec returns raw `toData`/`fromData` functions, but `Data.withSchema` expects `Schema`. Are we losing Effect's error channel by using synchronous encode/decode? What happens when encoding fails — do we get a useful ParseError or a raw throw? -2. **Question annotation coverage**: Are there real Plutus patterns that CANNOT be expressed via annotations alone? Can a user annotate a `Schema.Class` (Declaration AST)? What about branded types, newtypes, or opaque wrappers? -3. **Type safety audit**: Does `Plutus.data()` return a properly typed `Schema`? Or does it lose type information via `as any` casts? Can users compose `Plutus.data()` schemas with Effect's `Schema.compose`, `Schema.transform`, `Schema.filter`? -4. **Try to break it**: Write adversarial test cases designed to fail: - - Schema with index signatures (`Record`) - - Schema with optional properties (`Schema.optional(...)`) - - Schema.Class / Schema.TaggedClass as input to `Plutus.data()` - - Deeply nested transformations (3+ levels of Schema.transform) - - Union with non-struct members (e.g., `Schema.Union(Schema.BigIntFromSelf, Schema.Boolean)`) - - Empty union, single-member union - - Tuple with rest elements (`Schema.Array` inside a tuple) -5. **Compare with Haskell**: Pick 3 complex Plutus types from real contracts and verify the annotation system can express them. If not, document what's missing. -6. **Benchmark against TSchema**: For the same types, measure compilation time and encode/decode throughput. Is the compiler overhead justified? -7. **Review error quality**: Trigger every error path in the compiler. Are the messages actionable? Do they include the AST path? -8. **Fix or document**: For each issue found, either fix the code (with tests) or document it as a known limitation with a clear rationale for why it's acceptable. -**Output**: Adversarial test file + fixes + updated limitations doc, committed locally - -### Phase 12+: Continuous Improvement (repeating) -**Status**: pending -**Goal**: Each iteration picks the highest-value improvement from the backlog, implements it, and updates the backlog.

Known TSchema types (Boolean, NullOr, UndefinedOr) now use direct codec functions instead of `Schema.encodeSync`/`Schema.decodeSync`. Unknown TSchema transforms still fall back to the slow path. Encode with TSchema.Boolean field now within 3x of pure TSchema (was 5x). 250 tests passing. -2. **Implement flatFields in compiler** — Added `FlatFieldsId` support in TypeLiteral handler + `countStructFields` helper. When a field has `FlatFieldsId: true` (or TSchema's `"TSchema.flatFields": true`), its sub-fields are inlined into the parent Constr during encoding and reconstructed during decoding. Supports multiple flat fields, mixed flat+non-flat, backward compat with TSchema string annotations. 4 new tests, 254 total passing. -3. **Schema.Class support** — Transformation handler now detects `Transformation(from: TypeLiteral, to: Declaration)` pattern (Schema.Class/TaggedClass) and compiles the `from` side (TypeLiteral with struct fields) instead of falling through to passthrough. TaggedClass `_tag` field auto-stripped. 254 tests passing. -4. **Map auto-derivation** — Declaration handler detects Map/MapFromSelf via Description annotation starting with "Map<" and 2 typeParameters. Compiles key/value codecs recursively. Schema.Map (Transformation wrapper) handled via existing fallback `go(ast.to, path)`. Nested maps (Value pattern), maps in struct fields, CBOR byte-for-byte match with TSchema.Map. 5 new tests, 259 total passing. -5. **Effect error channel** — DEFERRED. Phase 11 confirmed: raw throws in codec are caught by `Schema.encodeSync`/`decodeSync` in `Data.withSchema`, so users already get `ParseError`. Converting all 22 Match handlers to return `Effect` would be massive churn for marginal benefit. Error messages already include paths. Acceptable tradeoff. -6. **Mutual recursion** — Already works! `memoizeThunk` in the Suspend handler + `Schema.suspend` handles both self-recursion and cross-schema cycles (A→B→A). Tested with Expr/BinOp pattern and A→B→A separate schemas. 2 new tests, 261 total passing. Phase 9 limitation removed. -7. **Module augmentation** — Added `declare module "effect/SchemaAST"` augmentation to `PlutusAnnotation.ts`. Symbol keys (`ConstrIndexId`, `EncodingId`, `FlatInUnionId`, `FlatFieldsId`, `TagFieldId`) are now typed on the `Annotations` interface with correct value types. TypeScript compilation passes. 1 new test, 262 total passing. -8. **Documentation** — Migration guide covering all patterns: primitives, struct (basic/nested/flat/tagged), sum types (Variant vs makeIsDataIndexed), Option, Map, Array, recursive types, Schema.Class, codec usage, real-world Address example. Side-by-side TSchema vs Plutus.data() with notes on API differences. -9. **Eliminate `as any`** — Removed all `as any` from production code (PlutusCompiler.ts: 10→0, PlutusSchema.ts: 4→0, PlutusAnnotation.ts: already 0). Used proper discriminated union narrowing for AST types, replaced return-type casts with `as unknown as Schema` with documented reasons. TypeScript compilation clean. 262 tests passing. -10. **Eliminate `as any` from tests** — 31→2 across 4 test files. Key fix: recursive schemas use `Schema.suspend((): Schema.Schema => X)` with explicit encoded type annotation — matches Effect's own test pattern from TSchema.recursive.test.ts. No casts needed. Remaining 2 are intentional wrong-type error tests (`"not a bigint" as any`). 262 tests passing. -11. **Edge case sweep** — 30 new tests across 10 handler categories. All pass without compiler fixes needed. Tested: tag-only structs, all-flat structs, field order, single-member unions, mixed primitive unions, NullOr(union), empty/nested tuples, double-wrapped suspend, all literal types (0n, negative, boolean, number, long string), empty/nested maps, nested flatFields, refinement chains, deeply nested heterogeneous roundtrip, null at every nesting level. No silent wrong output found. 292 total tests passing. -12. **Fix silent passthrough for unknown Declarations** — Declaration handler now throws by default for unrecognized types (following JSON Schema's approach). Added explicit detection: Set/HashSet/ReadonlySet→Set (CBOR list, decoded back to Set), List/Chunk→Array (CBOR list), HashMap/ReadonlyMap→Map (already handled). Date, Duration, FiberId, OptionFromSelf, SortedSet, custom Schema.declare all throw with descriptive error including path. 8 new tests (Set encode/decode, empty Set, ReadonlyMap, DateFromSelf/DurationFromSelf/OptionFromSelf throw, error path). 300 total tests passing. -13. **Benchmark improvements** — Comprehensive benchmark suite with proper warmup (5000 iterations each). Key finding: **Plutus.data() is at parity with TSchema** — earlier 3-5x overhead was warmup artifact. Results: 2-field encode 1.0x, 10-field encode 1.0x, Address (nested unions) 0.7x (Plutus faster!), decode 1.0x, CBOR roundtrip 1.0x. Schema.transform overhead: negligible (1.0x vs direct). AST compilation: 0.001ms. No optimization needed — the compiler adds zero measurable overhead. 8 new benchmark tests, 308 total passing. -14. **Enum shorthand** — Added `Plutus.makeEnum("Red", "Green", "Blue")` that auto-generates `makeIsDataIndexed` with empty fields and indices from declaration order. CBOR byte-for-byte match with manual equivalent. Works as field type inside `Plutus.data()`. 4 new tests (basic, CBOR match, 10+ variants, as field type). 312 total passing. +| # | Item | Result | +|---|------|--------| +| 1 | Reduce encode/decode overhead | TSchema fast-path codecs for Boolean, NullOr, UndefinedOr | +| 2 | Implement flatFields | FlatFieldsId annotation + countStructFields helper | +| 3 | Schema.Class support | Compile from-side TypeLiteral for Transformation→Declaration | +| 4 | Map auto-derivation | Detect Map/HashMap/ReadonlyMap via Description prefix | +| 5 | Effect error channel | DEFERRED — raw throws caught by Data.withSchema, acceptable | +| 6 | Mutual recursion | Already works via memoizeThunk + Schema.suspend | +| 7 | Module augmentation | declare module "effect/SchemaAST" for typed annotations | +| 8 | Documentation | Migration guide: TSchema vs Plutus.data() for all patterns | +| 9 | Eliminate `as any` (prod) | 14→0 using discriminated union narrowing | +| 10 | Eliminate `as any` (tests) | 31→2 using explicit encoded type in suspend thunks | +| 11 | Edge case sweep | 30 tests, zero bugs found | +| 12 | Fix silent passthrough | Unknown Declarations throw, added Set/List/Chunk/HashMap support | +| 13 | Benchmark improvements | Plutus.data() at parity with TSchema (1.0x), Address 0.7x faster | +| 14 | Enum shorthand | Plutus.makeEnum("A", "B", "C") with auto indices | +| 15 | Newtype flattening | DROPPED — use raw schema directly | +| 16 | Auto-index sum types | DROPPED — explicit indices safer than implicit key order | + +**Total**: 312 tests across 13 files, zero `as any` in production code, zero TypeScript errors. + +--- ## Rules for Loop Execution -1. **One phase per iteration** — complete the current pending phase, update its status to `done`, then stop -2. **Always commit** — after completing a phase, `git add` and `git commit` locally with a descriptive message -3. **Update the log** — append to `research-log.md` after each phase -4. **Use effect-local-source skill** — for ANY Effect source research, invoke this skill FIRST -5. **Annotation-first** — every implementation decision must use Effect's annotation system.

For the test file (`PlutusData.test.ts`): + - Are describe/it names clear and consistent? + - Are there any tests that test implementation details instead of behavior? + - Remove benchmark tests if they add noise without value (or move to a separate bench file) +4. For exports (`index.ts`, `package.json`): + - Do the exports match the module-export-pattern? + - Is anything exported that shouldn't be? +5.

If clean → update `.loop-phase` to Phase 5 --- -## Rules for Loop Execution - -1. **One phase per iteration** — complete the current pending phase, then stop -2. **Health check first** — run tests + tsc before committing (see "Every Phase: Non-Negotiable") -3. **Always commit** — `git add` + `git commit` locally with descriptive message after each phase -4. **Update the log** — structured entry in `research-log.md` (cycle, phase, action, result, next) -5. **Use effect-local-source skill** — for ANY Effect source research, invoke this skill FIRST -6. **Annotation-first** — use Effect's annotation system, never manual `switch(ast._tag)` -7. **Read before writing** — always read current state of tracking files before updating -8. **If stuck** — document what's blocking in the log, mark phase as `blocked`, skip to next -9. **Test each phase** — every phase that produces code must include passing tests -10. **No `as any`** — production: zero. Tests: only for intentional wrong-type error tests -11. **No convenience wrappers** — users compose from primitives (`data()`, `makeIsDataIndexed`, annotations) -12. **Draft before commit** — exploratory work goes in `_candidate-*.ts` files, promoted or discarded in the next phase +## Phase 5: PR Prep +Goal: Prepare the branch for a pull request. + +1. Run `git log --oneline main..HEAD` — review all commits on this branch +2. Squash or fixup any "research:" commits that aren't relevant to the final PR +3. Write a PR description covering: + - What: annotation-driven Plutus Data encoding using Effect's `Match` + `getCompiler` + - Why: standard Effect Schema types instead of TSchema-specific combinators + - API surface: `Plutus.data()`, `Plutus.codec()`, annotation symbols + - Test coverage: number of tests, what's covered + - Breaking changes: none (TSchema still works, this is additive) +4. Verify the branch is up to date with main (rebase if needed) +5. Do NOT push or create the PR — just prepare everything and stop +6.
