From 32a3f6de3e852ebc7eea2b59096bd0fe46641844 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 21 Sep 2026 13:49:34 +0000 Subject: [PATCH 01/42] feat(engine): single-source logic engine generating TypeScript, Python and Go MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Write a utility's logic once, in a restricted and semantically typed subset of TypeScript, and generate a native, idiomatic implementation for each target. No shared runtime package, no WASM, no FFI, no bridge, no interpreter at run time, and no external dependencies in the generated code. The engine (`engine/`) is domain neutral and self contained, so it can be extracted into its own repository later: one dependency (the parser), no build step, its own tests, and a generic example project that keeps any Brazilian Utils assumption from leaking into the compiler. `core/` is the first project that uses it: seven pilots — isValidCpf, isValidCnpj, formatCnpj, getHolidays, isBusinessDay, getAddressInfoByCep and formatCurrency — covering strings, refinements, ranges, regex, stable sorting, civil dates, exact decimals, HTTP with retry and a race, and a domain error hierarchy. How it works: source -> Semantic HIR -> Core IR -> per target lowering selection -> Target AST -> printer -> that language's own formatter. Types carry proofs (an integer's range, a string's character class and length), and a native lowering is selected only when its preconditions hold — which is why `str.compare` is native in Python and Go, where comparison is code point order, and portable in TypeScript, where `<` compares UTF-16 code units. Verified by `core: npm run verify`: 4252 differential cases through the reference interpreter and all three targets, in both idiom modes, plus 4245 cases compared against the published package; byte-identical regeneration; `tsc --strict`, `compileall` and `go vet` clean over the output. The three benchmarked pilots are faster than the handwritten implementations they replace (0.51x to 0.82x). Nothing in `src/` changes. `vite.config.ts` excludes the new directories from the package's own format, lint and test passes, since they carry their own toolchain.

Python's `//` and `%` are floored, so +the Python backend selects a native lowering only when both operands are proven non-negative and +a generated helper otherwise. Division and `%` require a divisor proven non-zero. + +### 2.2 Loops and widening + +Every loop has a proven trip count: counted `for` loops and `for…of` only, which is why `while` is +outside the subset. The checker re-checks a loop body until the types of its mutable locals stop +growing: + +- when the trip count is at most 64, the fixpoint is exact, and an accumulator ends with the range + it really has; +- above that, ranges widen to the platform-safe domain, and the loop is counted in the metrics. + +A widened counter may then be *clamped* back into that domain on assignment, but only while one +step is at most 2^22: since a loop runs at most 2^31 − 1 times, a bounded step cannot leave the +domain. A step the analysis cannot bound is an error, not a clamp. + +### 2.3 Strings + +A `String` is a sequence of Unicode scalars, and `length` counts scalars. + +- Generic strings support iteration by scalar (`str.codePoints`), concatenation, comparison and + the intrinsics. They never support positional indexing, because "position" means a UTF-16 code + unit in JavaScript, a byte in Go and a code point in Python. +- `str.codeAt`, `str.charAt` and `str.slice` are admitted only on `Ascii` (and therefore on + `Digits`), where the index means the same thing in all three targets and is O(1) in each. +- `str.trim` removes exactly the 25 code points JavaScript's `String#trim` removes. Python's + `str.strip()` also removes U+001C to U+001F and U+0085 and does not remove U+FEFF, so the Python + backend passes the cut set explicitly; Go's `strings.Trim` takes the cut set as an argument + anyway. +- Case mapping is ASCII-only: `str.asciiUpper` and `str.asciiLower` map `a-z` and `A-Z` and leave + every other scalar alone. Full Unicode case mapping is out of scope because the targets disagree + ("ß" uppercases to "SS" in JavaScript, Python, Java and Rust, and stays "ß" in Go's + `strings.ToUpper` and C#'s `ToUpperInvariant`). A proven-ASCII argument unlocks the host's own + case mapping, which is equivalent there; anything else uses the portable implementation. +- `str.compare` is scalar order. JavaScript's `<` compares UTF-16 code units, so an astral scalar + would sort *below* U+E000 there and *above* it in Python and Go; the TypeScript backend + therefore selects the native comparison only for proven-ASCII strings and the portable one + otherwise. +- Unicode normalization is out of scope. It depends on the host's UCD version, which differs + between runtimes and between Python releases. + +### 2.4 Decimal + +`Decimal` is an exact decimal whose scale is a compile-time constant, represented in every +target as its unscaled integer. + +- `+`, `-`, `*` and comparison are exact. Multiplication adds the scales. +- Division, rescale and conversion from a float name their scale **and** their rounding mode at + the call site. There is no hidden global context: Python's default 28-digit context and Java's + throwing `BigDecimal.divide` are exactly what this rule avoids. +- `dec.fromFloat` rounds the *exact binary value* of the double, which is why `1.005` at scale 2 + under `half-up` is `1.00`: the double is really 1.00499999999999989…. A host that formats + `1.005` as `1,01` (as `Intl.NumberFormat` does) is rounding the shortest decimal representation + instead, which is a different operation and belongs to the DX. + +### 2.5 Time + +`CivilDate` is a day on the proleptic Gregorian calendar, years 1 to 9999 — the range Python's +`date` and C#'s `DateOnly` share — represented everywhere as days since 1970-01-01. + +- `date.fromYmd` answers an `Option`: there is no implicit rollover. +- `dayOfWeek` is ISO: Monday is 1 through Sunday is 7. +- Month arithmetic is not admitted. When it is, it will have to name its overflow policy, because + JavaScript's `setMonth` rolls over (31 January + 1 month is 3 March) while Java's `plusMonths` + and C#'s `AddMonths` clamp. +- `Instant` is milliseconds since the Unix epoch and `Duration` is an exact count of + milliseconds. An `Instant` and a `CivilDate` are never interchangeable: converting between them + needs a zone, which is deferred, so a host date is the DX's problem. + +--- + +## 3. Refinements + +Refinements are what make an idiomatic native lowering safe. A lowering declares preconditions +over facts; without the fact, the portable implementation is selected. + +Facts: `Ascii`, `Digits`, `Matches`, integer ranges, string and list length ranges. + +They enter in four ways: + +1. **annotations**: `Digits`, `AsciiOf<14>`, `IntRange<0, 9>`, `List`; +2. **flow-sensitive analysis**: after `if (!re.test(PATTERN, value)) return …`, the rest of the + scope knows `value` matches the pattern, and therefore its class and its length range; a + `value.length !== 14` guard narrows the length; a comparison narrows an integer on both sides; + `x === undefined` narrows an `Option`; +3. **checked conversions**: `str.asAscii` and `str.asDigits` answer an `Option`; +4. **intrinsic guarantees**, declared by each intrinsic's signature. + +A fact crosses a function boundary by **specialization**: a library helper is checked once per +distinct call-site argument type, so `digitAt(cpf, index)` can serve an 11-digit CPF and a +14-digit CNPJ without either caller losing the proof it already had. Specializations that compile +to the same code are folded back together by the linker, which is sound precisely because the +types they differ in are proofs, not run-time structure. + +A utility — an exported function in a module at the source root — always keeps its declared +signature, because that signature is the published contract. + +--- + +## 4. Effects and capabilities + +Effects are `Pure`, `Fail`, `Http`, `Clock` and `Random`. The last three are capabilities. + +- An author calls `http.request(…)`, `clock.now()` or `random.nextU32()` and never mentions an + environment. The compiler infers effects over the call graph and threads a capability record + into exactly the functions that transitively need one. +- Each target generates its own default environment from its standard library — `fetch`, + `urllib.request`, `net/http`, the system clock, OS randomness. That is generated code, not a + runtime package. +- `Http` answers an `Option`: a transport error or a timeout is absence, and a 4xx or 5xx status + is an ordinary value. Retry and fallback are then written as ordinary control flow, which the + subset can express without `catch` (see [ADR 0006](decisions/0006-http-is-an-option.md)). +- `Random` offers only `nextU32`. Everything derived from it — a range by rejection sampling, a + shuffle — is written in source, so the algorithm and its bias are identical everywhere. +- **Async is computed, not written.** The TypeScript backend makes a function `async` exactly when + it reaches `Http`, and awaits its calls; Python and Go emit blocking code. + +### 4.1 Concurrency + +The only primitive is `task.race(tasks)`, admitted because looking a CEP up in several services at +once needs it. + +- Every task answers an `Option`; the race answers the first task that answers `some`, or `none`. +- Under the reference model — virtual clock, scripted Http latencies — "first" is virtual + completion time, ties broken by task index, so a race is compared deterministically. +- Cancellation is best effort and semantically unobservable: a losing task may run to completion + and its answer is dropped. Only idempotent work belongs inside a race. +- Lowerings: `Promise.any` in TypeScript, a `ThreadPoolExecutor` in Python, goroutines and a + channel in Go. + +--- + +## 5. Errors + +```ts +export class InvalidCepError extends DomainError {} + +throw new InvalidCepError("CEP inválido"); +``` + +Error classes have empty bodies. A `throw` becomes the effect `Fail`, and each target +represents it natively: exception classes in TypeScript and Python, `(T, error)` with typed errors +and `errors.Is` compatibility in Go. + +Bugs are not domain errors. Overflow, invalid indexing, division by zero and non-exhaustive +matches are proven impossible at compile time; there is no `catch` to fall back on. + +--- + +## 6. Regex + +A regex is a compile-time value, normalized into explicit code point classes. + +Rejected: lookaround, backreferences, lazy quantifiers, `.`, inline flags, unanchored patterns and +the shorthand classes `\d`, `\w`, `\s` and `\b` — JavaScript's `\d` is ASCII-only while Python's +matches every Unicode digit, and `\s` differs again. Write the class out; the compiler prints it +in each dialect's own syntax (`\uXXXX` in JavaScript and Python, `\x{…}` in RE2). + +Anchoring is supplied by the target: `^…$` in JavaScript (which are string anchors without the `m` +flag), `re.fullmatch` in Python, `\A…\z` in Go. + +The accepted subset is linear-time on backtracking engines as well, because there is no +alternation of overlapping classes under an unbounded quantifier. + +--- + +## 7. Subset + +**Rejected**, each with a diagnostic code and, where possible, the construct to write instead: + +`any`, `unknown`, bare `number`; `==`; truthiness of anything but `Bool`; `null`; `?.` and `??` +outside an `Option`; `this`, prototypes, getters and setters, classes with bodies; dynamic property +access; objects used as maps; escaping mutable values; closures that capture mutable locals; +effectful lambdas inside combinators; generators, custom iterators, `for…in`; `while`; generic +`try`/`catch`; host globals (`Date`, `Math`, `Intl`, `JSON`, `fetch`, timers, `console`); regex +constructs outside section 6; recursion. + +**Allowed**: `const` and `let` with local mutation; `if`/`else`; counted `for`; `for…of`; +`return`; `throw` of a declared domain error; `switch` over an `Enum` with exhaustiveness; +template literals and the ternary operator; immutable records; enums; `Option`; pure module-level +functions, including pure lambdas passed to combinators; `push` on a local list and assignment to +a local list element; `dataset`-style constant tables. + +Only locals are mutable. A list may be built with `push` and is frozen when it escapes its +construction scope, so aliasing behaves identically across Go slices, Python lists, Rust ownership +and JavaScript arrays. + +--- + +## 8. Admission rule for intrinsics + +An operation becomes an intrinsic only if all three hold: + +1. it cannot be expressed efficiently and idiomatically as source library code; +2. it has a precise specification, a reference implementation and vectors; +3. at least two utilities need it, or it is a prerequisite of an admitted intrinsic. + +The default answer is: write it in source. Check digits, Easter, holidays, business days, pt-BR +currency formatting and the JSON field reader behind the CEP lookup are all library code. + +Every intrinsic that some target cannot lower natively with proven equivalence has a portable +implementation in the engine's own source-language standard library (`stdlib/`), compiled like any +other module. That is what makes a new target complete as soon as its core constructs lower: +native lowerings are optimizations, not requirements. + +--- + +## 9. Lowering selection + +Each target declares, per intrinsic, the candidates it has, what each requires, and what each +costs.

The job runs `verify`, which regenerates every target in both idiom modes, diffs a second generation for determinism, runs each target's linters over the output, and runs the differential conformance harness. The root `tsconfig.json` now excludes those directories, the way the format, lint and test passes already do: the package's type checking stops at its own sources.

A local assigned just before a `continue` therefore re-entered the next iteration with its pre-loop type, and one assigned before a `break` was read after the loop with the same stale type. The fixpoint then converged on a range the loop actually exceeds, and every proof resting on that range, an unchecked `seq.get` among them, was unsound. Reproduced against the reference interpreter: the checker proved `Int[0..0]` for an accumulator the interpreter answers `15` for, and accepted an index the loop drives past the end. The loop body now reports the three ways it can be left, and the fixpoint merges the fall-through, `continue` and `break` states into the head on every pass; the state after the loop is the head joined with fall-through and the `break` states. The same repro is now rejected with the real range, `Int[0..15]`. A `break` that ends a `switch` case was also lowered as a loop break, so the generated Python left the enclosing loop where the source left the switch. The trailing case break is now dropped when the case is translated, and any other break inside a case is rejected with `E_SWITCH_BREAK` rather than silently mistranslated. `tests/loops.spec.ts` covers all of it.

Nothing caught it until a library module started taking a capability, because until then only root modules imported it. The support import now travels as the same `SUPPORT` sentinel the Python target already uses, and the printer resolves it against the module's own path, so `lib/cnpj.ts` reaches for `../capabilities.ts`. Also moves `groupThousands` and `easterSunday` out of the utilities that happened to define them and into `lib/`, restoring the one-export-per-file rule the source root is supposed to keep: the date construction both Easter and the fixed holidays need is now `lib/civil.ts`, so `get-holidays.ts` and `format-currency.ts` export a single utility again.

The `--no-idioms` trees stay out, being a comparison the verification builds rather than something anyone reads, and CI now fails when the committed output drifts from what the engine emits for the committed sources.

Everything past the single `random.nextU32` intrinsic is written in the subset — `lib/random.ts` derives a uniform value below a bound by rejection sampling rather than `% bound`, because the modulo bias of a fixed-width draw would otherwise have to match digit for digit across three unrelated standard libraries to stay invisible. The subset has no unbounded `while`, so both the rejection search and the repeated-base redraw are counted loops whose fallback probability is worked out in the comment that states it: under 2^-32 for the draw, under 10^-64 and 10^-88 for the bases. A base is built as straight-line concatenation rather than in a loop: a loop's fixpoint proves a range over every iteration, `Digits[0..12]`, not the exact length the check-digit functions require, while `str.concat` sums the bounds exactly. The three generated differential drivers used to answer 0 to every draw, and built one capability object for a whole batch. They now carry the reference PCG32, with the interpreter's own constants and default seed, constructed per request line the way the reference builds a fresh interpreter per case — so the comparison is call for call. The conformance run also derives an `isValidCpf`/`isValidCnpj` case from whatever the interpreter actually drew, which is what would catch three targets agreeing bit for bit on an invalid document. Conformance: 4256/4256 in every target, in both idiom modes; 4247/4247 against the published package.

Over a checked accessor that produced a conditional nested inside its own condition, six lines where one belongs; over a call it ran the call twice, so `get_address_info_by_cep` parsed each JSON field two times. The checked lowerings now build the conditional as a node instead of as text, so a default drops straight into the `else` branch, and anything else is bound once with a walrus. `opt.isNone` was text too, so negating it gave `not response is None`. It is a comparison node now, and the printer negates it to `response is not None`. Docstrings kept only the first line of the source doc, which cut sentences in half wherever the prose wraps. A doc that spans lines now keeps all of them, in the shape PEP 257 describes. Conformance is unchanged at 4256/4256 in every target and both idiom modes; the output is regenerated in the same commit.

The marginal-cost section now records what the two generators cost: one more intrinsic, `random.nextU32`, and no compiler change beyond it.

CI had neither, produced unformatted output, and reported it as a diff against the committed files. Prettier is now a pinned dev dependency of the engine, resolved from the engine's own `node_modules` and run with `--no-config` so an ancestor configuration cannot change the result; ruff is installed in the workflow at the version `toolchain.lock.json` records; gofmt comes with Go. `verify` now starts by checking all three are installed and fails if one is not, and the CLI warns on stderr when it leaves a target unformatted. The generated output is unchanged by all of this, which is the point.

This one asks it of three, against the implementations those communities actually ship: `brazilian-utils/python`, `brazilian-utils/go`, and this repository's own `src/` for JavaScript. Each harness runs in its own runtime and times itself, so nothing is measured across a process boundary, and every pair of implementations has to agree on every benchmarked input before either is timed — a disagreement is worth more than a number. The ports do not share one input contract, and the table says which was used rather than averaging over the difference. Python's `validate` and the generated core both take a digits-only value, so those rows compare directly. Go's `IsValid` normalizes internally, so it gets two rows: the full pipeline from the same raw masked input, which is what a caller of either library experiences, and the pre-normalized one. Two comparisons are left out entirely, with the reason recorded: Python's `format_cnpj` validates the checksum and the generated one does not, and the Go port's `Format` has no pad, obfuscate or alphanumeric option. Generated TypeScript is faster than the package it would replace (0.48x to 0.78x), generated Python is level with `brutils` (1.05x, 1.07x), and generated Go is 6.7x to 8.1x slower on the two validators while being 3.4x faster on `formatCnpj`. That split is a real defect in the Go lowering, not a harness artifact, and it is the next commit's problem. The ports are separate repositories, so this cannot run in CI; the commits the numbers were measured against are pinned in the README.

Feeding them a masked string would not +exercise their logic at all, so every Python row is `normalized`: both sides receive the same +pre-sanitized, mask-free string. This means the generated core is doing marginally more work than +strictly necessary even here (its regex still walks the string checking for mask characters that +aren't present), which is a small, known bias in the generated core's favor being *reported*, not +hidden. + +`brutils.cnpj.format_cnpj` is excluded entirely: it calls `is_valid` first and returns `None` on a +bad checksum, while the generated `formatCnpj` never validates a checksum at all. That's not a +normalization difference you can paper over with a shared input -- it's a different contract +(validate-then-format vs. format-unconditionally). Timing them against each other would mostly +measure the checksum computation Python's port does and the generated core does not, so no number +is published for it. + +**Go -- the one with a trap in it.** `cpf.IsValid`, `cnpj.IsValid`, `cpf.Format` and `cnpj.Format` +all normalize their input themselves, via `helpers.OnlyNumbers`: + +```go +func OnlyNumbers(numbers string) string { + numericStr := regexp.MustCompilePOSIX("[0-9]+").FindAllString(numbers, -1) + return strings.Join(numericStr[:], "") +} +``` + +which **compiles a POSIX regex on every call**, then allocates a `[]string` and joins it. There is +no lower-level entry point that skips this, so it cannot be avoided by calling "the checksum part +only" -- that part is unexported. Two variants are reported for `isValidCpf` and `isValidCnpj`: + +- `full-pipeline`: both sides receive the same raw, masked input, and each does its own + normalization plus validation. This is what a real caller of either library experiences, and + it's fair because both sides are doing equivalent work. +- `normalized`: both sides receive the same pre-stripped digit-only input. This isolates most of + the checksum work from the mask-stripping work, but not all of it -- the Go port's public + functions call `OnlyNumbers` unconditionally, so even here the handwritten side still compiles a + regex and rebuilds a string on every call, a cost the generated side does not pay once its input + is already digits-only. + +`formatCnpj` is compared only as `full-pipeline`, and only the plain case: the Go port's `Format` +has no `pad`, `obfuscate` or alphanumeric (version `2`) option, so those variants aren't +comparable and are left out. CNPJ validation is compared at version `"1"` (numeric) only, for the +same reason `IsValidCnpj`'s alphanumeric path has no counterpart -- `OnlyNumbers` strips letters +before the length check, so the Go port has no alphanumeric CNPJ support at all. + +None of this is a criticism of the Go port or a suggestion to change it -- it's read-only, nothing +here modifies it, and the observation is only about what the "normalized" numbers do and don't +isolate. + +## What the numbers actually showed + +Run `node core/bench/run.mjs` for current numbers; this section describes what was found while +building the harness, not a frozen result. + +- TypeScript and Python: the generated core lands close to its handwritten sibling (TypeScript + clearly faster across all three rows; Python within a few percent either way on both rows), and + every input in both languages produced identical answers on both sides. +- Go: `isValidCpf` and `isValidCnpj` came back roughly 6-9x *slower* on the generated side, on + both the `full-pipeline` and `normalized` variants, and this is real, not a harness artifact. + `core/out/go/is-valid-cpf.go` and `is-valid-cnpj.go` call `regexp.MustCompile(...)` **inline, + inside the function body**, so the (fairly large, Unicode-range-heavy) mask-detection regex is + recompiled from source on every single call, instead of being compiled once at package + initialization the way idiomatic Go does it. `formatCnpj`'s generated Go code does not have this + problem (it doesn't use a regex) and came back about 3x *faster* than the handwritten port. This + is worth flagging to whoever owns the Go code generation template -- `core/out/**` is another + agent's territory in this session, so nothing here was changed to fix it, but it is the single + most consequential finding this benchmark produced. +- No disagreements were found on any benchmarked input, in any language: every generated/ + handwritten pair returned the same answer for every value used here. + +## Rust + +Not benchmarked yet. `core/out/rust/` is being generated by another agent concurrently with this +work, and this harness was told not to wait for it or write its half. `run.mjs` already looks for +`core/out/rust/` and a `core/bench/rust/` harness and reports plainly why the Rust row is absent +if either is missing, so adding Rust later is: generate `core/out/rust/`, write +`core/bench/rust/` (a `cargo run --release` binary following the same shape as `go/bench_main.go` +-- warm-up, timed loop, `BENCH_JSON` line), and `run.mjs` picks it up with no changes. The +handwritten Rust port's contract was confirmed while investigating fairness for this benchmark: +`rust/src/cpf.rs::validate()` rejects anything that isn't already all-ASCII-digits of the exact +length before doing any work, the same digits-only contract as the Python port, so its future row +should follow the Python row's `normalized`-only shape rather than Go's two-variant shape. diff --git a/core/bench/go/bench_main.go b/core/bench/go/bench_main.go new file mode 100644 index 000000000..07ac539cb --- /dev/null +++ b/core/bench/go/bench_main.go @@ -0,0 +1,217 @@ +// Benchmarks the generated Go core against brazilian-utils/go, the handwritten package it +// replaces.

That split was the diagnosis: the Go target emitted `regexp.MustCompile` inline in the function body, and `regexp` has no compilation cache, so a large Unicode-class pattern was rebuilt from its source string on every call. Measured alone: 2257.5 ms to compile against 28.4 ms to match, over 200 000 iterations, 79.6x. Patterns are now lifted into package level `var`s, which is both the fix and what a Go author would have written. The same rows come back at 0.13x to 0.16x: about six times faster than the handwritten port rather than seven times slower. Only Go ever paid this. JavaScript caches a compiled regex literal and Python caches compiled patterns inside `re`, so the TypeScript benchmark had been green throughout and could not have found it. That is the argument for measuring against another language's real implementation instead of against yourself. Hoisted constant tables are now named after the module they came from (`libCnpjTable1` rather than `table1`). Every generated Go file shares one package, so two modules that each hoisted a bare `table1` would have redeclared it — latent until a second module hoisted one. Naming by module also keeps an unrelated new utility from renumbering the tables of every file that already had one. The Python printer upper cases a constant's references from the module's own constant list now, rather than from a pattern that guessed at the name and quietly missed anything shaped differently.

This carries the sketch out, and both predictions held without reaching for a crate: `Cargo.lock` lists exactly one package, the generated crate itself. No HTTP in `std` becomes a generated `Capabilities` trait the caller implements, `Sync`-bounded because `task.race` is `std::thread::scope`. No JSON in `std` becomes a hand-written codec used only by the differential driver. `Fail` is `Result` over one flat enum, so the fallible-call hoist the Go target needs collapses into `?` at print time. The sketch's central plan did not survive: it assumed `&str` and `&[T]` parameters, and borrowing cannot be decided where the pipeline decides things — a lowering runs before any function scope exists, and a printer sees one module without its callees' signatures. Every heap value is owned instead, with conversion at the few positions that need it. ADR 0009 records that, and `rust-sketch.md` now says where reality diverged from it rather than being quietly corrected. Rust conformance is 4256/4256 in both idiom modes, matching the other three targets, and `verify` grew `cargo build`, `cargo clippy -D warnings` and `cargo fmt --check`, so the crate is checked the way the other outputs are. The lowering mix is the interesting number: 250 native, 54 library, 2 portable, against Go's 277/27/2 and TypeScript's 304/0/2. `std`'s narrower surface pushes twice as much into generated helpers as any other target needed — which is the falsification doing its job, since it is a fact about Rust's standard library rather than anything about the Core. `core/bench/rust/` benchmarks it against `brazilian-utils/rust`, and the result is recorded rather than smoothed over: correct on every input, and 50x and 24x slower than the handwritten crate. The generated regex matcher is 79% of that, and it is the next commit's problem.

Deciding "does this argument need `&`" from the *callee's* + declared parameter type — the sketch's own model — needs exactly that cross-module signature + table, which nothing in the shared pipeline hands a backend. +- The Target AST carries no lifetimes at all (`backend/tast.ts` is shared by three targets with no + borrow checker), so there is no way to thread a lifetime parameter through a borrowed signature + even if the first two problems were solved. + +A borrowed-parameter design needs all three of these to hold the way a single hand-written Rust +function would take them for granted. None of them does, in this architecture. + +## Options + +**Borrow parameters, as sketched.** Requires either a whole-program pre-pass (computing every +function's owned-vs-borrowed signature before any lowering runs — a second traversal the other two +targets do not need) or accepting the timing gap above as a known-broken edge case. Neither is a +small addition; the second is a bug, not a design. + +**Own everything, decide ownership only at print time, only where it is unavoidable.** A function +parameter, a struct field, a `Vec` element are all `String`/`Vec`/`T` (owned). Borrowing appears +only where Rust supplies one for free: a method's `&self` receiver, a `for` loop's `.iter()`, a +`std`-provided helper's own `&str`/`&[T]` signature (which this backend's support functions use +throughout, and which candidates borrow into explicitly with `borrowed()`). The one recurring cost +is `.to_owned()` at the handful of positions that actually build an owned value — a `let`, a +`return`, a record field, a list item, `Some(...)`, a call argument — and those are exactly the +positions `docs/semantics.md` already treats as escape points, so the sketch's frozen-on-escape +insight is not wasted, only relocated from "which parameters borrow" to "which expressions need +`toOwned`. + +## Decision + +Every heap-typed value — parameter, local, struct field — is owned. `toOwned(expr, expectedType)` +converts a bare name, a field read or a string literal into an owned value at exactly the positions +that need one; everywhere else, `print` is used directly and never allocates on its own account. +`toOwned` reaches for `.to_owned()` uniformly, never `.clone()`: the blanket `impl +ToOwned for T` makes `.to_owned()` exactly as correct on an already-owned value (a clone) as on a +reference (`&str` → `String`), so the printer never has to know which one it is looking at, and +`clippy::clone_on_copy` — which matches the method name `clone`, not `to_owned` — never fires on a +`Copy` value that happened to go through this path. + +A related simplification travels with this one: `CoreError` is a single flat enum (one variant per +declared domain error), not one error type per utility the way Go's `error` interface and each +target's own error hierarchy might suggest. Every fallible function returning `Result` +is what makes the shared lowerer's Go-shaped `multiLet` + `if err != nil` hoist collapse into a +plain `f(...)?` at print time — there is never a type for `?` to bridge, because there is only ever +one error type in the whole program. + +## Consequences + +- **A few more clones than a hand-tuned Rust port would write.** A value passed to two different + calls is `.to_owned()`'d at both, not moved at the last one; the backend does not attempt a + last-use analysis. Given the actual generated code (nine document-formatting and lookup + utilities, not a hot loop over millions of records), this is the right place to spend simplicity + rather than the wrong one to spend allocations. +- **`opt.unwrap` needs a second form.** `Option::unwrap` takes `self` by value, unlike a Go pointer + dereference, which is free to repeat. A Core-narrowed field read (`if x === undefined { return }` + then `x.field`, possibly several times) re-inserts `opt.unwrap` at every read, since the Core + never re-types the local narrower — so a narrowed read goes through `.as_ref().unwrap()` (a + borrow) instead of a bare `.unwrap()` whenever it is immediately followed by a field access. See + `docs/targets/rust.md`'s note on the same lowering. +- **`task.race`'s closures borrow, not `move`.** A `move` closure would take ownership of whatever + it captures, and two tasks built from the same argument (`fetch_via_cep(cep, env)` and + `fetch_brasil_api(cep, env)`, both closing over `cep`) cannot both move it. Since every capture + here is read-only, an ordinary (non-`move`) closure borrows instead, and any number of tasks can + share the same borrow. +- **Support functions (`support.rs`) still take `&str`/`&[T]`.** They are called the way `std`'s + own functions are — read-only, any number of times, including from inside a loop — which is + exactly the shape a borrow is for.

The benchmark put that at 79% of `is_valid_cpf` — 266.9 ms of 339.5 ms over 200 000 iterations — and the whole utility at 50x the handwritten crate. The engine knows every pattern before the program runs, so there is no reason to interpret a tree afterwards. A pattern that is a chain of character-class runs, with no alternation and no two adjacent variable-length runs that could overlap, is emitted as a dedicated straight-line scanner that consumes each run greedily in one pass over `&str` and allocates nothing. Anything the classifier refuses falls back to a backtracking matcher over a static pattern tree — also allocation-free, and a direct port of the reference matcher in `regex.ts`, so `regex.spec.ts` already covers its behaviour. The rule that decides between them is written down rather than implied, and every pattern this project uses takes the scanner. `tests/rust-regex.spec.ts` compiles and runs the generated driver over ten patterns spanning both paths against `RegExp`, including one where a greedy scanner would be wrong and the classifier has to refuse it. `re_test` drops from 266.9 ms to 4.4 ms; `isValidCpf` goes from 50x to 10.9x the handwritten crate and `isValidCnpj` from 24x to 3.6x, which puts the latter level with generated Go. Conformance is 4256/4256 in both idiom modes either way, and `Cargo.lock` still lists exactly one package. What remains is measured, not guessed, and it is not the regex: `cpf_check_digit` calls a string-taking helper inside its loop, and every value is owned, so it clones an 11-character string once per weight. That is 44.9 ms of the remaining 78.0 ms. `cnpj_check_digit` indexes bytes directly and shows no such cost, which is why CNPJ is 3.6x and CPF is 10.9x although CNPJ validates more digits. Fixing it means inferring which parameters are only read, and that supersedes ADR 0009 rather than extending it, so it is recorded instead. Also: `LOWERING.md` claims to record the rule that decided every selection, and it was dropping the rule whenever a candidate won unopposed — only the ones with a rejected rival printed their reasoning. All four targets now explain themselves either way.

Every value in the Core is owned wherever it is bound ([ADR +0009](../../engine/docs/decisions/0009-rust-values-are-owned.md)), so each call to the +`digit_at(value: String, ...)` helper needs its own owned copy of the 11-digit string -- one +`to_owned()` per loop iteration, not one per top-level call, because the loop calls a +String-taking helper instead of indexing bytes directly. `cpf_check_digit(_, 9)` alone, at 44.9 ms, +accounts for most of the remaining gap; the other `cpf_check_digit(_, 10)` call, `is_repeated`, and +two more `digit_at` calls in `is_valid_cpf` itself make up the rest. This is the ownership-clone +cost the coordinator's original measurement called "about 1%" and asked not to be spent on -- +correct as stated (one clone at one call site is about 1% of the *old*, regex-dominated call) but +multiplied here by a loop the regex fix does not touch and this task did not ask to: the fix is +scoped to `re.test`, and ADR 0009's ownership model is explicitly out of scope. `cnpj_check_digit` +does not have this cost -- its source indexes `cnpj.as_bytes()[index]` directly rather than calling +a String-taking helper in its loop -- which is exactly why `isValidCnpj`'s gap (3.6x) is so much +smaller than `isValidCpf`'s (10.8x) despite CNPJ validating more digits: the difference is which +loop-body shape `core/source` happens to use, not the pattern each one matches. + +The mask-tolerance asymmetry the coordinator's note anticipated (`brazilian_utils::cpf::validate` +rejects anything not already digit-only; the generated core accepts and re-normalizes masked +input) is real but small next to the above: `re_match_3` still walks the full 11-character input +once even when it is already digits-only, on the order of a few milliseconds here, not the +dominant term. + +Against Go (`core/bench/README.md`'s Go section above), generated Rust now roughly matches +`isValidCnpj` (53.5 ms vs. Go's 49.0 ms normalized) but is still behind on `isValidCpf` (79.3 ms +vs. Go's 39.9 ms normalized) -- both by the same `cpf_check_digit` loop, which Go's target also +lowers to a String-taking helper call but without Rust's per-call ownership cost to pay for it. +Closing that gap further means changing how a loop that calls a helper repeatedly is lowered (or +revisiting ADR 0009's borrowing decision), not anything about `re.test`, and is future work rather +than part of this fix. diff --git a/core/out/go/LOWERING.md b/core/out/go/LOWERING.md index 3a6d81dc0..ed657e871 100644 --- a/core/out/go/LOWERING.md +++ b/core/out/go/LOWERING.md @@ -92,26 +92,26 @@ with, the implementation that was selected, and the rule that decided it. | `int.add` | `Int[8..352], Int[15..15]` | native | only candidate, cost none/constant | | `int.add` | `Int[9..2147483671], Int[0..3]` | native | only candidate, cost none/constant | | `int.add` | `Int[9..9], Int[1..1]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-3506022..3798461], Int[1460..1460]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-3506022..3798461], Int[146096..146096]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-3506022..3798461], Int[36524..36524]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-3508743..3800988], Int[365..365]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-36547261..36546653], Int[5..5]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-36547328..36546742], Int[153..153]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-9600..10399], Int[100..100]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-9600..10399], Int[4..4]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-9612..10413], Int[100..100]` | native | only candidate, cost none/constant | -| `int.div` | `Int[-9612..10413], Int[4..4]` | native | only candidate, cost none/constant | -| `int.div` | `Int[0..469], Int[451..451]` | native | only candidate, cost none/constant | -| `int.div` | `Int[0..99], Int[4..4]` | native | only candidate, cost none/constant | -| `int.div` | `Int[0..9999], Int[400..400]` | native | only candidate, cost none/constant | -| `int.div` | `Int[107..149], Int[31..31]` | native | only candidate, cost none/constant | -| `int.div` | `Int[19..20], Int[3..3]` | native | only candidate, cost none/constant | -| `int.div` | `Int[19..20], Int[4..4]` | native | only candidate, cost none/constant | -| `int.div` | `Int[1900..2099], Int[100..100]` | native | only candidate, cost none/constant | -| `int.div` | `Int[2..1685], Int[5..5]` | native | only candidate, cost none/constant | -| `int.div` | `Int[27..28], Int[25..25]` | native | only candidate, cost none/constant | -| `int.div` | `Int[306..3652364], Int[146097..146097]` | native | only candidate, cost none/constant | +| `int.div` | `Int[-3506022..3798461], Int[1460..1460]` | native | only candidate, cost none/constant;

That was necessary but not sufficient — a later cross-language benchmark +(200 000 iterations of `isValidCpf`/`isValidCnpj` against the handwritten `brazilian-utils/rust` +crate) found the generated code 24-50x slower even with compilation gone, because the *matcher* +itself, walking that `ReNode` tree, allocated a fresh `Vec` of reachable positions per node +per position and sorted and deduplicated each one: dozens of heap allocations per call for a +14-character input. `support::re_test` alone was 79% of the call. + +The engine knows every pattern in a project before it generates a line of Rust, so the real fix is +to stop interpreting a tree at call time at all. `engine/src/targets/rust/index.ts`'s "Regex" +section compiles each pattern into one of two things, decided once, at generation time: + +- **A dedicated scanner** (`re_match_N`, in `support.rs`), for a pattern that is a top-level chain + of character classes and repeated character classes with no alternation and no repeated group — + every pattern `core/source` actually uses. `chainElementsOf` additionally requires that any + variable-length run have a class disjoint from whatever immediately follows it (maximal munch: + the two classes can never disagree about where one run ends and the next begins), which is what + lets the emitted scanner consume each run greedily, in one forward pass over `&str`, and never + need to back off. It is built from two small generic helpers, `re_take_fixed`/`re_take_class`, + that slice the input forward; nothing here allocates. +- **The fallback matcher** (`re_test`/`ReNode`, still in `support.rs`), for anything + `chainElementsOf` refuses — alternation anywhere, or a repeated group more complex than one + class. This is no longer the position-set NFA: it is continuation-passing backtracking over + `&str` byte slices, a direct port of `regex.ts`'s own reference matcher (`matchNode`), which is + what every accepted pattern is already checked against in `engine/tests/regex.spec.ts`. Its + continuations are stack-local closures borrowed with `&dyn Fn`, never boxed, so it does not + allocate either — the `Vec` `re_test` used to collect the input into, and the per-node + `Vec`, are both just gone, not replaced with a differently-shaped allocation. + +No pattern in `core/source` takes the fallback path today; `LOWERING.md`'s `re.test` row and the +`because` string in `RUST_CANDIDATES` name the rule that decides, so a reviewer does not have to +infer it from which patterns happen to appear. Re-measured, `support::re_match_3` (the CPF +pattern's scanner) alone is on the order of the input's own length to walk once — see +`core/bench/README.md`'s Rust section for the current numbers and what dominates the call now that +the matcher no longer does. **`int.max`/`int.min`** detect a nested clamp (`x.max(lo).min(hi)`, the shape the source's own `int.min(int.max(x, lo), hi)` prints as by default) and merge it into `.clamp(lo, hi)`, which diff --git a/engine/src/backend/select.ts b/engine/src/backend/select.ts index e51cf1e04..2214349c5 100644 --- a/engine/src/backend/select.ts +++ b/engine/src/backend/select.ts @@ -109,10 +109,14 @@ export class LoweringTable { return IMPL_RANK[left.impl] - IMPL_RANK[right.impl]; }); const chosen = ordered[0]!; + // An unopposed candidate still has a reason, and it used to be dropped: `LOWERING.md` is + // supposed to record the rule that decided every selection, not only the ones that had a + // rival to reject. + const why = chosen.because === undefined ?

The pattern is known when the code is generated, so it is compiled then. That is also what a Python author would write, and it puts Python alongside Go and Rust, which already had their patterns lifted out of the call path. `isValidCpf` goes from 1.05x the handwritten `brutils` to 0.89x, and `isValidCnpj` from 1.02x to 0.80x — faster than the package it would replace, while still accepting the mask characters `brutils.cpf.validate` rejects outright.

It now covers every utility each port has a counterpart for: `formatCurrency` everywhere, `generateCpf` and `generateCnpj` everywhere, and `getHolidays` and `isBusinessDay` against this repository's own `src/`, since no port has a year-list form to compare with. `getAddressInfoByCep` stays out everywhere, because it performs real requests. Random output cannot be compared for equality, so the generators get their own agreement rule: every value either side produces has to validate under both that port's validator and the generated one, five hundred samples per run, before anything is timed. None produced an invalid document. Four rows came back over budget, each with the construct responsible named and measured rather than left as a ratio: the TypeScript generators spend at least 97% of the call inside `crypto.getRandomValues`, which is 130x the cost of the `Math.random()` the published package documents using; TypeScript's `getHolidays` spends 78% in `civilDate` verifying a round trip the handwritten version gets from `new Date`; Python's `formatCurrency` runs three to six interpreter-level calls per character in `groupThousands`; and Rust's string assembly allocates at every step. It also found a disagreement worth more than any row. On a negative amount the Python, Go and Rust ports all answer `R$ -1.234,56`, while the generated core answers `-R$ 1.234,56` — and so does this package's own `src/`, and so does `Intl.NumberFormat("pt-BR")`, which the core's contract was measured from. Three community ports agree with each other and diverge from the package this pipeline traces its contract to. Left as a finding rather than settled in either direction, with a negative value in every harness so it stays visible.

This is the same shape of cost the CPF/CNPJ +section above documents, but ADR 0010's fix does not reach it: `format_currency`'s own signature +takes `value: i64` and returns an owned `String` -- there is no `String`/`List` parameter here for +the borrow pre-pass to find borrowable in the first place, and the function's job (building a new +formatted string) inherently allocates regardless of ownership. + +For `generateCpf`/`generateCnpj`, `cpf_check_digit` is no longer a factor at all (0.1 ms for one +call, the same near-zero cost the CPF/CNPJ section above measures for the pair together): the +entire remaining cost is `random_cpf_base`/`random_cnpj_base` -- about 109 ms of 140 ms and 142 ms +of 183 ms respectively. Both call `random_digit`/`random_below` once per digit (9 times for CPF, 12 +for CNPJ), and each of those returns an owned `String` (`.to_string()`) that then gets threaded +through a `concat2` chain to build the base -- the same "many small owned allocations, one per +digit, chained together" pattern TypeScript's capability section above describes for a different +reason (there, the RNG call itself is the expensive part; here, `next_u32()` is cheap and the +wrapping and String-building around each draw is what adds up). None of `random_digit`/ +`random_below`'s own parameters are `String`/`List` either (they take and return `i64`/`String` +built fresh each call, nothing to borrow), so this cost sits outside what ADR 0010 changes, the +same way `format_currency`'s does.

What it missed is that both are about *when* a decision is made, not about whether the information exists — `lowerProgram` is handed the whole `CProgram`, every signature and every call, before it lowers any of it. So the decision moves earlier. `analysis/borrows.ts` walks the program to a fixpoint and marks each `String`/`List` parameter that is only ever read: never returned, never stored into a value that outlives the call, never assigned to, and never passed to a parameter that is itself owned. The lowering and the printer consult that map rather than making the judgement themselves. Record fields and return types stay owned, because lifetimes in generated structs are a different and much larger change. `cpf_check_digit(cpf: String)` becomes `cpf_check_digit(cpf: &str)`, and its loop stops cloning an eleven-character string once per weight: that one call goes from 44.9 ms to 0.1 ms per 200 000 iterations, and `isValidCpf` against the handwritten crate from 10.89x to 2.20x. The clones that remain are in functions that genuinely produce owned values. ADR 0010 records this and supersedes 0009 in place, which is left standing rather than rewritten — a decision that turned out to be too conservative is worth keeping legible. Conformance is 4256/4256 in both idiom modes, `Cargo.lock` still lists exactly one package, and clippy and rustfmt are clean.

Neither of those is a mistake in 0009's reasoning, and this decision +does not relitigate them. + +What 0009 missed is that both obstacles are about *when* a decision is made, not about whether the +information exists. `lowerProgram` receives a `CProgram` with every function in it — every +signature, every call, every module — before it lowers a single one of them. The two problems 0009 +found are both instances of one fact: deciding "does this parameter borrow" *during* lowering or +*during* printing does not have enough context. Deciding it *before* lowering starts, over the +whole program at once, does. + +The cost 0009 accepted for owning everything was not hypothetical. `docs/targets/rust.md` and +`core/bench/README.md`'s Rust section measured it directly: `cpf_check_digit`'s loop called +`digit_at(cpf.to_owned(), index)` once per weight (9 to 11 times per call), because `digit_at` +took `value: String` and every call argument was cloned to build it. That loop was 44.9 ms of the +78.0 ms `is_valid_cpf` cost at 200 000 iterations — more than half the call, for a value that +`digit_at` and `cpf_check_digit` both only ever read. `cnpj_check_digit` has no such cost, because +its own source indexes `cnpj.as_bytes()[index]` directly instead of calling a `String`-taking +helper in a loop; that accident of which loop-body shape `core/source` happens to use is the entire +reason `isValidCnpj` (3.59x the handwritten crate) looked so much better than `isValidCpf` +(10.89x) despite validating more digits. Generated Go, on the same benchmark, was already faster +than generated Rust on both rows — a systems language with automatic memory management beating one +with an ownership model it was not using. + +## Decision + +A pre-pass (`analysis/borrows.ts`, `computeBorrowableParams`) walks the whole `CProgram` once, +before any target-specific lowering runs, and decides which `String`- and `Enum`- and `List`-typed +function parameters may be printed as `&str`/`&[T]` instead of `String`/`Vec`. The search starts +**optimistic**: every eligible parameter is assumed borrowable, and a parameter is **demoted** to +owned the moment direct evidence shows it needs to be — returned, stored into a record field, a +list element or a thrown error's payload, assigned to, or forwarded unchanged to a parameter of +another function that already needs to be owned. That last rule is a fixpoint over the call graph: +whenever a callee's parameter is found to need ownership, every caller that forwards its own +parameter into it, bare and unchanged, is demoted too, and the demotion is applied with a worklist +over the reverse call graph until nothing more changes. Starting optimistic and demoting is sound +here specifically because demotion only ever *adds* to the owned set — never removes from it — so +the set of "still borrowable" parameters shrinks monotonically to a fixpoint no matter what order +the evidence is found in; `docs/semantics.md` §7 forbids recursion, so the call graph has no +cycles and the worklist provably terminates (each key enters the queue at most once). + +The result — a `BorrowMap`, from a function's fully qualified name to the names of its own +borrowable parameters — is handed to the shared lowerer as an input (`LowerOptions.borrows`) and +to the Rust printer as data already baked into the Target AST, not as something either of them +computes: + +- `Lowerer.lowerFunction` looks the map up once per function, before lowering that function's body, + and sets `TParam.borrowed` on each parameter accordingly. `printFunction` reads that field to + decide `&str`/`&[T]` vs. `String`/`Vec` in the signature; it does not re-derive it. +- Every "local" reference the lowerer builds (`Lowerer.expr`'s `"local"` case) carries `borrowed: + true` when it names one of the *current* function's own borrowed parameters. This is the fix for + 0009's exact timing problem: a candidate's `emit` can now ask a plain data field on the `TExpr` + it already has in hand, at whatever point during lowering it runs, instead of needing a + per-function scope that does not exist yet. +- Every "call" node carries `borrowedArgs`, one flag per argument, set from the *callee's* entry in + the same `BorrowMap` at the point the call is lowered (`Lowerer.expr`'s `"call"` case already has + the callee's `CFunc` in hand there). The printer's `call` case reads it directly: an argument the + callee only reads is passed with `&`, everything else still goes through the existing + `toOwned`/`callArg` path, unchanged. +- The Rust backend supplies the pre-pass to the shared pipeline through one new, optional hook on + `Backend` (`extraLowerOptions: (program) => Partial`), merged into `LowerOptions` + before `lowerProgram` runs. `generate.ts` stays target-independent — it calls the hook if the + backend defines one and does nothing otherwise — and Go, Python and TypeScript, which define no + such hook, are unaffected in every sense that matters: same code path, same output, same + conformance, because `LowerOptions.borrows` is `undefined` for them and every place that reads it + treats `undefined` as "owned", exactly 0009's model. + +Record fields and every function's return type stay owned, unconditionally — this decision does +not touch either. A borrowed field would need a lifetime parameter on the struct itself +(`struct Foo<'a> { name: &'a str }`), which is a materially larger change (every consumer of that +struct now carries a lifetime too) for a benefit this task was not measuring; a borrowed return +type is not expressible without one either, since nothing borrowed can outlive the call that +produced it. `toOwned` already converts a borrow to an owned value uniformly at both positions +(`&str`'s `.to_owned()` and `String`'s `.to_owned()` are the same call, printed the same way), so +nothing about them needed to change for parameters to start borrowing. + +### Why this is sound, position by position + +Every position that builds an owned value in the Rust backend — a `let`, a `return`, a record +field, a list item, `Some(...)`, an owning call argument — already goes through `toOwned`, and +`toOwned`'s `.to_owned()` on a name is exactly as correct whether that name is a `String` or a +`&str` (0009's own point about `.to_owned()` vs. `.clone()`, unchanged by this decision). That is +what makes the four demotion rules a genuine *optimization* question rather than a *correctness* +one: nothing here is unsound to skip, in the sense of producing code that fails to compile. What +each rule actually buys is not needing a clone at all where a bare move or a bare borrow now +suffices instead: + +- **Returned, or reaches a return through another value.** Returning an owned parameter can be a + move (`return param;`, free); returning a borrowed one needs a clone (`return param.to_owned();`) + because nothing borrowed can be handed out past the call. Keeping it owned keeps that path free. + A local that is a bare, untransformed alias of the parameter (`let x = param;`) inherits the same + treatment, because at the exact point that alias was built, it went through `toOwned` already — + whatever the parameter's own status, that clone happened once, there; nothing about the + parameter's declared type changes after that. +- **Stored into a record field, a list element or a thrown error's payload.** Same shape as above: + a field, an item or an error payload is always built owned, so the parameter being owned instead + of borrowed only matters for whether that specific write can be a move. +- **Assigned to.** `check.ts` marks every parameter binding `mutable: false`, so this never actually + fires against an unshadowed parameter today — a mutable local can share a parameter's name only + by shadowing it with its own `let`, which the alias tracking in `analysis/borrows.ts` already + treats as a break in the alias (a fresh, independent, owned local from that `let` on). The rule + is kept anyway, as a static safety net: if the source subset ever admits a form of parameter + mutation, this rule already demotes the right parameter without anyone having to remember to add + it then. +- **Forwarded to a parameter of another function that is itself owned.** A thin forwarding function + (`f(s) { return g(s); }`, `s` used nowhere else) that keeps its own parameter owned can hand `s` + to `g` as a move if `g` needs it owned, instead of paying a clone at that internal call; keeping + `f`'s own parameter borrowed would force that clone every time `f` is called instead. This is + the one rule that is not purely local to one function, which is why it is a fixpoint over the + call graph rather than a single pass over one function's body. + +Two things this pass deliberately does not chase, both because they cost nothing to leave alone, +given the design above: + +- **Last-use elision.** `toOwned`'s `"name"` case still clones unconditionally on every occurrence, + even the last one, even for an already-owned local — the same simplification 0009 named and + accepted ("the backend does not attempt a last-use analysis"). This decision does not add one. + What it removes is the clone an *owned call argument* needed only because the parameter itself + was declared owned when the callee never asked for that; it does not remove the clone a + genuinely-owned value pays when it is used more than once. +- **An intrinsic's own operands.** `str.concat`, `str.padStart` and the rest of `RUST_CANDIDATES` + already borrow their own arguments, through the existing `borrowed()` helper, independently of + this map — that is the "Support functions still take `&str`/`&[T]`" half of 0009, untouched. + What *did* need a fix, because parameters can now genuinely be `&str`/`&[T]` themselves, is + `borrowed()`'s own `"name"` case: wrapping an already-borrowed name in another `&` would print + `&&str`/`&&[T]` — harmless at compile time (Rust's coercion resolves it) but exactly what + `clippy::needless_borrow` exists to flag under `-D warnings`. `borrowed()` now checks the same + `borrowed` field `Lowerer.expr` sets on every "local" reference (and the existing + `hoistedConstantNames` check, for a hoisted `&'static [T]` table) before deciding to add a `&`. + +## Consequences + +- **`is_valid_cpf`'s loop cost is gone, not reduced.** `cpf_check_digit`'s own parameter, and + `digit_at`'s, are both borrowable (each only reads its `value`), so `cpf_check_digit`'s loop is + `digit_at(cpf, index)` — a bare `&str` copy, not a clone — at every iteration. Re-measured, + `cpf_check_digit(_, 9)` and `cpf_check_digit(_, 10)` together cost about 2.2 ms over 200 000 + calls, against 44.9 ms for one of the two before this decision. +- **The new bottleneck is `keep_digits`, not ownership.** With the loop's clones gone, + `is_valid_cpf`'s single remaining allocation-heavy step is `keep_digits`'s own + `.chars().filter().collect::()`, building the fresh, necessarily-owned value the function + returns — about 9-9.5 ms of `is_valid_cpf`'s ~16.8 ms, next to `re.test`'s ~4.4 ms (unchanged; + this decision does not touch regex) and well under 1 ms for `is_repeated` plus the now-free + `cpf_check_digit` calls. `core/bench/README.md`'s Rust section has the full attribution and the + before/after benchmark. +- **Generated Rust now beats generated Go on both CPF and CNPJ rows** (it did not, before this + decision), the specific regression this decision exists to close. +- **A hand-written port would still borrow a few things this pass keeps owned.** The alias tracking + in `analysis/borrows.ts` only follows a *bare* `let x = param;` as a continued alias; a parameter + threaded through a `Record` field, or read inside a combinator lambda in a way more indirect than + a bare capture-and-return, is not traced past that point, and the record/list/error-payload rule + above is evidence-based rather than data-flow-complete (it looks at the immediate write, not at + what later happens to the container). Where this pass cannot prove a parameter's status either + way through those paths, it does not demote it — the parameter simply stays eligible and ends up + borrowed if nothing else demotes it first, or a hand-written port would sometimes make a sharper + call than this pass does in the other direction, on a value it can see is never touched again + after a store this pass conservatively still credits toward "escapes".

The package these utilities are modeled on says the opposite, in its own doc comment: "Uses `Math.random()` internally, so it is not cryptographically secure, do not use for security purposes." Generating an example document is not a security operation, and the engine had quietly decided otherwise. It cost what that choice costs: `crypto.getRandomValues` measures 434.9 ms per 200 000 draws against 3.3 ms for `Math.random()`, roughly 130x, and a generator draws once per digit. `generateCpf` was 55.24x the handwritten implementation and is now 1.50x; `generateCnpj` was 49.73x and is now 1.28x. Both are inside the benchmark's budget for the first time. Go and Rust ship no default at all — `std` has no RNG and Go's support file declares the interface — so a caller supplies one there either way, and nothing changes for them. Conformance is unaffected in every target, since the differential harness has always passed its own seeded capability.

Capability threading then added an `env` parameter, and it reached the public surface: the generated TypeScript exported `getAddressInfoByCep(cep, env)` and `generateCpf(env)` while the package they would replace export `getAddressInfoByCep(cep)` and `generateCpf(state?)`. The output could be read but not dropped in. An exported entry point now keeps the signature its source declares and delegates to a capability-taking form built once at module load. The threading is unchanged; it just stops being the caller's problem. The conformance driver calls the seam directly, so the differential run still injects its own clock, RNG and scripted HTTP, and every target still matches 4256/4256 in both idiom modes. Go and Rust get no wrapper, and that is a finding rather than an omission: neither generates a default capability at all, because `std` has no HTTP client or RNG and Go's support file declares only the interface. Fabricating one would mean vendoring a dependency those ports do not have. There the capability-taking form stays the only entry point, marked as such in `API.json` and explained in ADR 0011. Second defect, same cause of divergence: `getWithRetry`, `isOk`, `fetchViaCep` and `fetchBrasilApi` are private in the source and were exported in every generated module. A generated module now exports exactly what its source module exports, in each language's own idiom — `export` in TypeScript, a leading underscore and `__all__` in Python, `pub` against `pub(crate)` in Rust. Go already matched, having no file-level privacy to get wrong.

A DX author reading `API.json` sees the utility's real signature where they +would look for it, and sees separately, not folded silently into the same list, that this +particular utility has an internal form taking capabilities, without mistaking that form itself +for a second utility. + +**Go and Rust get no wrapper.** Both generate the `Capabilities` interface/trait only — no HTTP +client, no clock, no RNG, anywhere in the generated *library* (`support.go`, `support.rs`); the +fake either differential driver builds lives in the driver binary (`cmd/driver`, `src/bin/driver`), +never in the crate or package a consumer would import. There is nothing standing in for +`defaultCapabilities()` to build a singleton from, and one is not fabricated for the sake of +producing a wrapper. `splitCapabilityEntryPoints` is target-generic; whether a target gets a +wrapper is entirely decided by whether `Backend.defaultCapabilities` is present, and Go's and +Rust's backend objects simply do not define it.

Until now the evidence was 64 hand-written tests and translation validation over two programs — which is not a search, and the two soundness bugs found so far were both found by a person reading code. `src/fuzz/` generates well-typed programs in the subset from a seed, biased toward what actually broke: `break` and `continue` in every position, an accumulator carried across iterations, nested loops, a `switch` inside a loop, indices derived from loop counters. Fast mode runs the reference interpreter and checks that every value produced lies inside the range, length and character class the checker proved. Full mode generates all four targets in both idiom modes and compares. Both shrink, and every program is addressed by `(seed, index)`, so a finding replays exactly. It found four bugs on its first real run, three of them fixed at the source: - **A `switch`'s effect on a local never left the `switch`.** The checker computed each case's ending state for exhaustiveness and then restored the state from before — so an assignment inside a case was invisible afterwards. A loop multiplying an accumulator inside a case was proven to leave it unchanged while the interpreter returned 1024. That is the third bug of one family: a control-flow construct whose effect does not reach the code after it, after `break`/`continue` and the switch-case break mistranslation. - **The TypeScript backend's `switch` fell through every case.** The Core drops the source's case-closing `break` by design, and the printer took that literally — but JS `switch` falls through without one. Go, Python and Rust were unaffected. - **The optimizer folded an accumulator to `const` that was reassigned later.** `raiseLoops` checked only the statement after the loop, so a second loop over the same accumulator left a `const` two statements from its own reassignment: a TypeScript runtime error, a Rust compile error, and a silently wrong value in Python and Go. `tests/switch.spec.ts` pins the first one with four cases, verified to fail without the fix — a finding that only a seed can reproduce is not yet a test. Two more the fuzzer exposed, both in Go, both fixed here: a `for…of` whose body never reads its binding produced `for _, e := range` that Go refuses to compile, and the generated differential driver asserted a JSON array straight to `[]int` when `encoding/json` always produces `[]interface{}` — so the harness could not have tested any function taking a list at all. `core` has no such entry point, which is exactly why four thousand conformance cases never noticed. `verify` now runs a thousand programs in fast mode on every run. Conformance is unchanged at 4256/4256 per target in both idiom modes, and `core/out` does not move: none of this touches what the pilot project generates.

Two reasons pulled the other way: + +1. **The engine has exactly one runtime dependency (`oxc-parser`), and that restraint is + deliberate** — see the one-line "Deliberately absent" callouts throughout `semantics.md`. Taking + `fast-check` as a second one to generate test input is a strange trade for a project whose whole + design argument is "prove it, don't depend on a library proving it for you." +2. **A property-testing library's arbitraries compose *values*.** What this generator needs to + compose is *statements that stay well-typed as they accumulate a range* — an `Int.map`/`chain` + pipeline does not know that pushing a fourth statement into a loop body has to keep the whole + body provable by the checker afterward. That bookkeeping (`src/fuzz/generate.ts`'s `Ctx`, tracking + which locals are safe to index and which are in scope at all) is the actual content of a program + generator for this language, and `fast-check` would not remove any of it — only its low-level + `Random`/shrinking plumbing would be reused, and that plumbing is a few dozen lines to hand-roll + (`src/fuzz/rng.ts`) against the wall of API surface a real dependency would carry. + +So: a 32-bit seeded PRNG (`rng.ts`, mulberry32 + a splitmix32 sub-seed derivation), a small +generator-owned AST with its own printer (`ast.ts`), a recursive generator over that AST +(`generate.ts`), and a delta-debugging shrinker over the same AST (`shrink.ts`) — a few hundred +lines total, no new dependency, all reviewable the same way the rest of the compiler is. + +## What it generates, and what it deliberately does not + +Every generated program is one exported function, biased toward the shapes that broke the checker +before (see `generate.ts`'s module doc for the exact weighting): + +- loops with `break`/`continue` in every position, including a `break`-then-fall-through-to-`else` + shape that specifically exercises what a loop's fixpoint carries out of a conditional branch; +- an accumulator (`Int`, `boolean`, or a code-point list built into a string) carried across + iterations, including through `break`/`continue`; +- nested loops, up to two deep; +- a `switch` over a generated `Enum`, sometimes nested inside a loop; +- an index into a list, generated *only* where the generator itself can see it is safe — a counted + loop's own counter, ranging over a same-length list's `.length` — which is exactly the shape the + `break`/`continue` fixpoint bug lived in (`docs/semantics.md` section 7's `E_SIGNATURE` example, + and `tests/loops.spec.ts`); +- integer division and modulo with a proven non-zero literal divisor, which is what exercises the + Python backend's truncated-vs-floored divergence (`docs/semantics.md` section 2.1); +- occasionally (one list per function, capped — see `generate.ts`) a list long enough to push a + loop past the 64-iteration exact-fixpoint threshold into the widen/clamp path + (`docs/semantics.md` section 2.2), not just the small exact case the historical bug happened to + trip on; +- an early `return` from inside a loop. + +Every mutable integer local is declared `Int` — the full platform-safe domain — never a tight +`IntRange`. This is not a simplification that dodges the interesting bugs: the checker still infers +and proves a *tight* range for the local on every assignment regardless of its declared ceiling, +and that tight range is exactly what Layer 1 (below) checks the interpreter's real answer against. +Declaring `Int` only means the compiler never rejects a program for accumulating past its author's +stated intent — which is not the analysis this generator exercises — and it is what makes free-form +generation of arithmetic tractable without re-implementing the checker's own interval arithmetic to +predict, before generating an expression, exactly how wide an annotation it would need. + +**Deliberately absent**, to keep the generator's own surface reviewable: records, `Decimal`, +`CivilDate`/`Instant`/`Duration`, `Http`/`Clock`/`Random` capabilities, `task.race`, `throw`, +template literals, and `String`/`Ascii` function parameters (string values only appear as the +*output* of building a code-point list with `str.fromCodePoints`, not as generated input). None of +these are where the known bugs lived, and the bias list above is what the task asked this generator +to hunt for. Extending the generator to any of them is straightforward: add a case to the `Shape` +union and a branch to the relevant `gen*` function in `generate.ts`. + +## The two comparisons + +`src/fuzz/harness.ts` runs each generated program two ways: + +- **`runFast` — checker against reality (Layer 1).** Compiles the program, runs the reference + interpreter on random inputs (`values.ts`'s `randomValue`, biased toward each type's own edges), + and checks that every value it actually produced lies inside the range, length and character + class the checker proved for it (`values.ts`'s `withinType`). No code generation at all, which is + what makes it cheap enough to run in the thousands on every `verify` — see "Wiring" below. This + is exactly the shape of the `break`/`continue` bug: the checker proved a range, and the question + is whether reality (the interpreter, which follows real control flow) agrees. +- **`runFull` — interpreter against all four targets, in both idiom modes (Layers 2/3).** Generates + TypeScript, Python, Go and Rust from the same compiled program and compares every answer against + the interpreter's, reusing `src/conformance/differential.ts`'s `runInterpreter`/`runTarget`/ + `compare` exactly as `core/conformance/run.ts` drives them by hand — this generator does not + reimplement that machinery, only supplies it with generated cases instead of hand-written ones. + Compiling and running four toolchains is slow, so `runFull` first compiles every candidate program + on its own (an inexpensive pass — the same one `runFast` does) and only pays for code generation + and four builds on the survivors, batched into one project so the cost is paid once per batch, not + once per program. + +A program that fails to compile is not a finding: the generator is not required to produce only +well-typed programs by construction (see `generate.ts`'s module doc on why that would mean +re-implementing the checker's own type inference to generate goal-directed expressions), only to +generate *mostly* well-typed ones and let the compiler be the filter. Both modes report the +compile success rate for this reason. + +## Seed and shrink + +Every program is addressed by a `(seed, index)` pair (`rng.ts`'s `subSeed`), so replaying +`--seed --count 1` after adding `--seed` reproduces bit-for-bit the same program the batch +produced at index 0, independent of what batch size or machine produced the original finding. A +report always prints the seed next to the finding for exactly this reason. + +A finding is shrunk before it is reported (`shrink.ts`): + +- **`shrinkInputs`** narrows the failing argument tuple toward the edge of each parameter's own + type (zero, `false`, an empty or shorter list) without touching the program at all — cheap, since + it costs one interpreter call per trial, no recompilation. +- **`shrinkProgram`** narrows the program itself, one delta-debugging pass at a time: drop a + statement, drop an `if`'s `else`, drop a `switch` case. Every candidate is recompiled and rejected + outright if it no longer type-checks, so a shrunk report is always itself a valid program in the + subset. `runFast`'s violations are shrunk this way (`shrinkViolation`); `runFull`'s four-target + divergences are reported with the program the generator produced, unshrunk — recompiling and + rebuilding four toolchains per shrink trial is too slow to run automatically, so a full-mode + finding is a starting point for a person's own minimization, not a final answer the way a fast-mode + one is. + +## Wiring + +`scripts/verify.ts` runs `fuzz fast` with a small, fixed seed on every verification — no code +generation, so it costs seconds, not minutes. `fuzz full` is not wired into `verify`: it is run +deliberately, with a larger budget, exactly like `core/conformance/run.ts` is run deliberately +rather than on every keystroke. + +```sh +node scripts/fuzz.ts fast --seed 20260921 --count 5000 +node scripts/fuzz.ts full --seed 20260921 --count 300 --targets typescript,python,go,rust +``` + +A new target's own conformance story (`adding-a-target.md` step 5) should include a `fuzz full` run +restricted to it (`--targets `) alongside the differential conformance harness: the generator +does not know which target it is comparing, so a new backend gets the same generated coverage the +first four did for free. + +## Findings + +The generator's first runs at scale found four bugs, none of which the 64 hand-written cases or +the two translation-validation programs reached. Three were small enough to fix on the spot and +are already fixed in this tree; the fourth is reported and left, per this project's own rule that a +found bug is the deliverable, not a failure to be smoothed over. + +### Fixed: a `switch`'s effect on a mutable local never left the `switch` (Layer 1) + +`seed 12345 --count 300`, program `program::fuzz_185` (auto-shrunk); minimal form: + +```ts +export type Kind = "A" | "B"; + +export function f(p1: List, 7, 7>, kind: Kind): Int { + let acc: Int = -8; + for (const e of p1) { + switch (kind) { + case "B": + acc *= -2; + break; + default: + break; + } + } + return acc; +} +``` + +`core/check.ts`'s `switchStatement` collected the type-state at the end of every case (`exits`) — +used to check exhaustiveness — but the state was never merged back into the enclosing scope: the +function restored the pre-switch snapshot and returned without ever calling `applyJoin`. The +checker proved `f`'s return was `Int[-8..-8]` (the switch, in its model, changes nothing) while the +interpreter, calling `f([0,0,0,0,0,0,0], "B")`, actually returned `1024` — `-8 * (-2)^7`, seven real +multiplications the checker never saw. This is the same shape as the historical `break`/`continue` +bug the checker's tests already guard against — a control-flow construct's effect not reaching the +point after it — just in `switch` instead of a loop. Every `if`/`else` in the same function was +already threaded correctly; `switch` was the one construct that dropped its own state on the floor. +The fix (`checkFunction.switchStatement`) joins the ending state of every case that can fall off +its own end (skipping one that always `return`s or leaves the loop, the same distinction `if` +already draws) into the scope after the switch — nine lines, and the fixed case now proves +`Int[-512..1024]`, which matches what the interpreter really computes. + +### Fixed: a generated TypeScript `switch` fell through every case (Layer 3, TypeScript only) + +`seed 1 --count 10`, program `program::fuzz_2`; the interpreter and the TypeScript target disagreed +on every one of 3 cases in both idiom modes. `core/check.ts`'s `caseBody` correctly drops the +source's own case-closing `break` on the way into Core — documented in `docs/semantics.md` section +7, because the Core's `switch` never falls through and a target that printed the Core's cases as a +bare chain would read a kept `break` as leaving the enclosing loop instead. The TypeScript printer +(`targets/typescript/index.ts`) took that documented fact one step too literally: it printed each +case's body with nothing after it at all. JavaScript's `switch` *does* fall through without an +explicit `break`, so every case ran every case below it too — a single matching case pushed three +or four values into the accumulator instead of one. Go's `switch` does not fall through, Python is +compiled to an `if`/`elif` chain, and Rust's `match` arms don't fall through either, so this was +TypeScript-only. The fix appends an unconditional `break;` after every case and the `default` +(cheaper and just as sound as proving which bodies already exit on their own, since an unreachable +`break` after a `return` is harmless). `core`'s own source has no `switch` at all, so this had zero +effect on its committed output or conformance numbers — exactly the kind of gap only a generator +that writes `switch` reaches. + +### Fixed: an accumulator raised to a `const fold` was reassigned again later in the same function (Layers 1 and 3, every target) + +`seed 2 --count 50`, program `program::fuzz_20`; the TypeScript target threw +`TypeError: Assignment to constant variable.` at run time (a genuine Core-level bug, not a +TypeScript-only one — see below). Minimal form: + +```ts +export function f(p1: List, 3, 3>): Int { + let acc: Int = 10; + for (const e of p1) { + acc += e; + } + for (let i = 0; i < p1.length; i++) { + acc -= p1[i]; + } + return acc; +} +``` + +`optimize/optimize.ts`'s `raiseLoops` turns `let acc = init; for (x of xs) { acc = update; }` into +`const acc = seq.fold(xs, init, (acc, x) => update)` — sound on its own, and a nice simplification +every backend can choose to print as a native fold. It decides this by looking only at the +statement immediately after the loop; it never checked whether `acc` is assigned again *anywhere +later* in the function. Here it is: the second loop still reassigns `acc`. The pass raised the +first loop anyway, declared `acc` immutable, and left the second loop's plain `acc -= p1[i]` +untouched — a `const` two lines away from its own reassignment. This is a Core-level pass, so it +was not really "TypeScript's bug": Rust would have refused to compile it outright ("cannot assign +twice to immutable variable"), and Python and Go would likely have run it "successfully" while +silently keeping the wrong (unfolded-and-never-updated-again) value in the const case, which is +worse. The fix (`isReassignedLater`) walks the rest of the function body — including inside a +nested `if`, loop or `switch` — before raising, and skips the transform if `acc` is reassigned +anywhere in it. + +### Reported, not fixed: an unused `for…of` binding produces invalid Go + +`seed 2 --count 50`, program `program::fuzz_0` (one of several in that batch); Go's `go vet` refuses +the whole file with `declared and not used: e`. Minimal form: + +```ts +export function f(p1: List, 3, 3>): Int { + let acc: Int = 0; + for (const e of p1) { + acc += 1; + } + return acc; +} +``` + +The subset allows a `for…of` whose body never touches the bound element — nothing in +`docs/semantics.md` requires it, and a hand-written source could easily do the same thing on +purpose (counting elements, say). `targets/go/index.ts`'s `forEach` printer always names the +binding (`for _, e := range …`); Go requires every named local to be used, so an untouched one is a +compile error, and it takes down every function in the same generated file, not just the one that +has it. The natural fix is for the Go backend to print `_` when the loop body never references the +name. That check has to walk the *printed* Target AST rather than the Core's, because the printer +can still legitimately choose a lowering that references the loop variable in text the Target AST +does not model as a node (`adding-a-target.md`'s warning about `raw` emissions hiding what is +inside them from every later pass) — a correct fix has to either prove no such `raw` text exists in +the body or fall back to "assume used" whenever it might, and getting that exactly right was not a +small enough change to make confidently in the time this task had. Left as found, with this +reproduction and `node scripts/fuzz.ts full --seed 2 --count 1 --targets go` to replay it. + +### Not an engine bug: the generator's own nesting depth had an off-by-one + +Also found at scale, and worth recording because it looked exactly like a hang at first: two +loop-nesting parameters (`generate.ts`'s "one list per function may be 'wide' enough to force the +64-iteration widen/clamp path" and "loops nest up to two deep") were each safe in isolation but +compounded once they landed in the same function. A budget meant to allow at most two nested loops +let a third one through (the budget was spent only when *choosing* to nest, not when a loop was +actually created), so a generated program could range three loops deep, all three over the same +"wide", roughly-90-element list — about 90³ ≈ 730,000 executions of a body that pushes onto a list +with `push`'s copy-the-whole-list-per-call semantics (`interp.ts`), which is quadratic in the +list's own length. That combination made one generated program's *interpretation* — not its +compilation — take minutes, which is what made an early full run of `fuzz fast` look hung rather +than slow. Fixed in the generator (one extra `- 1`, `generate.ts`), not in the engine: nothing the +checker or the interpreter proved was wrong, the reference interpreter's `push` is simply not +written for the input sizes three-deep nesting of a "wide" list produces, and no hand-written +utility's loop nests three deep over a 90-element list today. Recorded here rather than silently +fixed because it shaped the generator's own depth and width defaults, which a reader tuning them +later should know about. diff --git a/engine/docs/semantics.md b/engine/docs/semantics.md index d0daf4c2e..7d39e98ca 100644 --- a/engine/docs/semantics.md +++ b/engine/docs/semantics.md @@ -362,6 +362,14 @@ requests. ## 10.

Today the author must write `Int` or `IntRange`. The range is what every +later proof rests on — an unchecked index, an `int` that did not have to become a `bigint`, a +native lowering chosen over a portable one — so it cannot simply be assumed. + +It does not have to be written down, though. Inside a function the range is already inferred, by +the same abstract interpretation the loop fixpoint runs. What is missing is a contract at the +boundary, and there are two places to find one without an annotation: a **guard the author already +writes** (`if (n < 0 || n > 99) return 0;` is a proof), and the **call sites** of a helper, which +the checker already specializes per call site. What remains after those two is an exported +function whose body guards nothing — and there the answer is a diagnostic naming the guard to add, +not a silent assumption and not a silently slower lowering. + +### `while` — `E_WHILE` + +```ts +while (index < n) { + total += index; + index++; +} +``` + +Refused because nothing bounds it, and every range the checker proves depends on a loop running a +knowable number of times. A counted `for` carries its own bound. To accept `while`, the condition +has to yield one — a variable that provably moves toward the bound by at least a fixed step — or +the loop needs a declared ceiling. Reachable, and the most valuable single item after `number`. + +### Destructuring — `E_DESTRUCTURING` + +```ts +const { x, y } = point; +const [first, second] = pair; +``` + +Pure syntax. It desugars to field reads the subset already has, and nothing about it is hard; it +is refused only because the frontend never learned it. + +### Default and optional parameters — `E_PARAM_PATTERN`, `E_SIGNATURE` + +```ts +export function greet(name: string, upper: boolean = false): string; +export function maybeSuffix(value: string, suffix?: string): string; +``` + +A default desugars to a conditional at entry. An optional parameter is `T | undefined`, which the +Core already models as `Option`. Both are close to free and both are what a normal signature looks +like. + +### Discriminated unions — `E_UNION`, `E_SWITCH_SUBJECT`, `E_MEMBER` + +```ts +type Shape = { kind: "circle"; radius: number } | { kind: "square"; side: number }; +``` + +The one genuine type-system feature missing. `core/docs/survey.md` counts this among what the +remaining 18 of 138 utilities need. It requires a sum type in the Core and a representation in each +target — a tagged struct in Go, an `enum` in Rust, a tagged dataclass in Python, a tagged object in +TypeScript — plus exhaustiveness on the tag, which the `switch` checker mostly has already. + +### `Map` and `Set` — `E_NEW`, `E_METHOD`, `E_MEMBER` + +```ts +const seen = new Set(); +``` + +Also counted in the survey's remaining 18. The obstacle is not the data structure, it is that +**iteration order has to mean the same thing everywhere**: JavaScript's `Map` iterates in insertion +order, Go's map iteration is deliberately randomized, Python's `dict` is insertion-ordered, and +Rust's `HashMap` is unordered. Supporting it means picking insertion order and generating it, not +mapping onto whatever each language calls a map. + +### Recursion — `E_RECURSION` + +```ts +export function factorial(n: number): number { + return n <= 1 ? 1 : n * factorial(n - 1); +} +``` + +Refused because nothing bounds the depth, and a generated Rust or Go program has a real stack. +Two ways out, both partial: self-tail-recursion can become a loop mechanically, and a depth the +checker can bound makes the rest safe. General recursion with an unbounded depth stays out. + +### `try`/`catch` — `E_TRY` + +```ts +try { + return Number.parseInt(value, 10); +} catch { + return 0; +} +``` + +The one where the languages genuinely disagree. Rust has no exceptions, Go has no `try`, and the +Core already expresses failure as an effect (`Fail`) that becomes `Result` in Rust, a second +return value in Go, and a raise in Python and TypeScript. A narrow `try`/`catch` around a call that +fails could map onto that. Arbitrary `try` around arbitrary code cannot, and should keep being +refused with a diagnostic that names the shape that works. + +### Method call syntax — `E_METHOD` + +```ts +value.split("-").join(" ").toUpperCase().trim() +``` + +Not a missing capability — every one of these exists as an intrinsic. The frontend simply does not +read the method spelling yet. This is the recognizer's job and it is in progress. + +## Accepted today + +`??` on an `Option`, counted `for`, `for…of`, `break`, `continue`, early `return`, `switch` over an +enum with exhaustiveness, template literals, the ternary operator, immutable records, `push` on a +local list, pure lambdas passed to combinators, `throw` of a declared domain error. + +`.filter()`, `.map()` and `.reduce()` are accepted as shapes; what fails on them today is the range +of the result, which is the `number` inference above rather than the combinator itself. + +## How this file is meant to end + +Every row moves to "accepted", or stays with a diagnostic that tells an author what to write +instead — in ordinary code, naming the construct and why it has no equivalent, never in this +engine's vocabulary. A row that stays is a fact about the four languages, not a gap in the engine, +and it has to read that way to the person who hits it. From 0bc275b24ad44ab7e8ba567d57f93845513cb8e9 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 21 Sep 2026 21:30:24 +0000 Subject: [PATCH 28/42] feat(engine): read ordinary TypeScript, not only the engine's namespaces MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Today a utility must be written in the engine's vocabulary — `str.codeAt(s, i)`, `seq.at(xs, i)`, `int.min(a, b)` — and the result is a source tree that compiles as TypeScript but does not run: `str`, `re` and `seq` are ambient declarations with nothing behind them. Importing `isValidCpf` and calling it fails with `ReferenceError: re is not defined`. That is the gap between "we write TypeScript" and the truth. The frontend now reads the ordinary spelling as well: `s.charCodeAt(i)`, `s.charAt(i)`, `s[i]`, `s.slice(a, b)`, `s.trim()`, `s.padStart(n, c)`, `s.length`, `String(n)`, `n.toString()`, `[...s]`, `PATTERN.test(s)`, `xs[i]`, `xs.length`, and `Math.min`/`max`/`abs`/`trunc`/`floor`. Both spellings are accepted, so nothing breaks while the mapping grows, and `core/out` does not move by a single byte — a diff there would mean a mapping changed meaning rather than spelling. The refusals are the more interesting half, because these forms mean JavaScript-specific things. `charCodeAt` is a UTF-16 code unit and the Core's scalar only coincides with it on ASCII, so on a value that is not proven ASCII it is rejected rather than silently lowered — and the same for `s[i]` and `s.slice`. `xs[i]` lowers to the unchecked accessor when the index is proven and to the checked one, an `Option`, when it is not, which is the difference between JavaScript answering `undefined` and Go and Rust panicking. `Math.random()`, `new Date(...)`, list spreading and `.replace` without `g` are each refused with what to write instead. `tests/idioms.spec.ts` proves each mapped form produces the same Core as the namespace spelling it replaces — that equivalence is the whole correctness argument — and pins every refusal.

"The author writes TypeScript" was not true, and saying it anyway would have been a lie to whoever used this. The source now uses the ordinary spelling wherever the frontend reads it: `.charCodeAt(i)`, `.replace(/[^0-9]/g, "")`, `PATTERN.test(s)`, `.trim()`, `.padStart(n, c)`, `String(n)`, `Math.min`/`max`, `xs[i]`. `isValidCpf` and `isValidCnpj` now execute in plain Node with no engine involved and answer correctly. `conformance (source, no engine)` is a new verify step that proves it rather than claiming it: it imports the utilities and runs the same vectors against them, with no compilation and no generation. `isValidCpf` matches 1519 of 1519. `isValidCnpj` matches 1216 of 2032, the rest blocked on one named gap, and the step fails if either number moves in either direction — a gap that closes silently and a utility that stops running are both things worth knowing. Seven utilities do not run yet, each for a reason the step names: `dec.*` because JavaScript has no exact decimal, `random.nextU32` and `http.request` because they are effects, `date.*` because `new Date` has no proleptic-Gregorian equivalent, and `formatCnpj` because `formatWithPattern` reaches a checked accessor on every call. `core/docs/idiomatic-migration.md` assesses, honestly and without implementing any of it, whether importing a real module could give each of them an ordinary spelling — `Temporal` is plausible for dates, a decimal library is harder because the scale is a type parameter here and a value there, and randomness, HTTP and `race` are not spellings of the same shape at all. Three call sites deliberately keep the namespace form, each with a comment: the index is provable there, so the bracket spelling would select the unchecked accessor — a different Core, not the same meaning respelled. The generated output does not move: the entire diff is four `SOURCEMAP.json` files, whose byte offsets into the source necessarily shift when the source text does. No generated program logic changed, in any target, in either idiom mode, and conformance holds at 4256/4256 throughout.

Both are added to +`engine/prelude/index.d.ts`.

That is a different Core, not the +same one respelled, and it would move `core/out` by more than a rename.

Also independently un-migratable + regardless of specialization — see "The checked numeric accessor" below. +- `lib/format.ts`, `patternSlots` and `formatWithPattern`: `str.charAtOpt(pattern, index) ??

The idiom table +recognizes `value[i]` as `str.charAtOpt`, the checked *string* form (JavaScript's own bracket index +on a string answers `undefined` past the end), but `value.charCodeAt(i)` answers `NaN` past the +end, not `undefined`, so it can only stand for the unchecked `str.codeAt`. There is no ordinary +JavaScript expression whose "past the end" behavior is `undefined` and whose in-range behavior is +a number. This is a smaller instance of the same gap as the five below, not one of them — it +blocks one helper, not a whole capability. + +Effect on this migration: `is-valid-cnpj.ts`'s alphanumeric (`version: "2"`) path calls +`hasLetter` unconditionally once `cleaned` is non-empty, so it is the one place this specific gap +is externally visible: `isValidCnpj` runs correctly for every numeric-format case and for every +`version: "2"` case where the sanitized value is empty, and throws for the rest. `format-cnpj.ts` +is worse off — `formatWithPattern` always scans a fixed-length pattern, so *every* `formatCnpj` +call reaches the equivalent gap (`str.charAtOpt`) and none can run yet. Both are documented and +asserted precisely in `conformance/run-source.ts` (see below), not silently downgraded. + +### The five effects, and whether "a real import of a real module" is honest here + +The task frames a real import of a real module as categorically different from an ambient +declaration with nothing behind it — an author reaching for a date or decimal library is ordinary +TypeScript, and the engine recognizing a known module's API is not the same kind of lie. Assessed +honestly, per capability: + +**`date.*` — a date library (e.g. Temporal, `date-fns`, `luxon`).** This is the strongest +candidate. A real `Temporal.PlainDate` (or a well-known library's date-only type) has exactly the +shape `CivilDate` wants: no zone, 1-indexed months, and a constructor that throws or clamps instead +of silently rolling over — the three complaints `E_HOST_DATE` raises about `new Date` do not apply +to it. Recognizing a specific, pinned version of `Temporal` or one library's API and lowering it to +`date.*` is plausible future work, not a change of kind: the semantics genuinely match, unlike +`new Date`, where they do not. The obstacle is scope and churn, not soundness: pinning a dependency +inside what is meant to be dependency-free source, and keeping the recognizer synchronized with +that library's exact surface across versions. + +**`dec.*` — a decimal library (e.g. `decimal.js`, `big.js`).** Also plausible in principle: these +libraries do carry an explicit scale and explicit rounding, which is exactly what `dec.*` requires +and `Number` cannot give. The harder part is that `Decimal`'s scale is a *compile-time* type +parameter the checker uses to keep `add`/`sub` type-safe and to size the generated integer in every +target; a real library's scale lives at the value level, checked at runtime if at all. Recognizing +the *values* a call produces is plausible; recognizing the *compile-time scale discipline* is a +larger design question than swapping a call's spelling, closer to admitting a new kind of +refinement than to adding a row to the idiom table. + +**`random.nextU32` — no.** `Math.random()` is already rejected (`E_MATH_RANDOM`) for the reason +section 4 gives: it is a float in `[0, 1)`, and turning that into an unbiased integer needs a +scaling step that would have to round identically across JavaScript, Python, Go and Rust to stay +unbiased — exactly the kind of target-dependent arithmetic the engine exists to keep out. A real +CSPRNG module (`node:crypto`'s `randomInt`, `crypto.getRandomValues`) is closer, since it can +already produce an unbiased integer in a range directly. But it is a *Node* module, not a portable +one: the whole reason `random.nextU32` exists as a capability, rather than a call to `crypto` +inline, is that Python, Go and Rust each generate their own default environment from their own +standard library (`docs/semantics.md` §4) — recognizing `node:crypto` would tie the ordinary +spelling to one target's runtime, which the capability model specifically avoids. Recognizing it +only for the TypeScript target and requiring the namespace form elsewhere would split the idiom +table by target, which the table's whole design (`tests/idioms.spec.ts` proves *one* Core for both +spellings) does not accommodate today. + +**`http.request` — no, for the reason semantics.md already gives.** `fetch` returns a +`Promise` whose status and body are two separate awaits, and it fails by rejecting rather +than by answering absent. `http.request` answers a plain `Option` with the body +already read. These are different *shapes*, not different spellings of the same shape — recognizing +`fetch(...)` would mean silently collapsing `await fetch(url).then(r => r.json())` into a single +synchronous-looking call, which is exactly the kind of "different operation with the same name" +`.replace()` is refused for (section 6/7.1). A library that already returns `Option`-shaped, +already-read responses could in principle be recognized the way a date or decimal library could; +`fetch` itself cannot be, regardless of how it is imported. + +**`task.race` — no, and for a sharper reason than the others.** `Promise.any` is the closest native +shape, but the engine's semantics are explicitly deterministic under a *virtual* clock (`docs/ +semantics.md` §4.2: "first" is virtual completion time, ties broken by task index) so that a race +is reproducible in conformance testing. `Promise.any` races on the real event loop; recognizing it +would mean recognizing a construct whose result depends on real scheduling, which is the one +property the capability model is built to avoid. No import changes that. + +**`clock.sleep`/`clock.millis` — not asked for, but the same shape as the others.** No ordinary +spelling exists for these either (a raw `setTimeout`/`Promise` pair is real JavaScript but is not a +respelling of a synchronous-looking capability call), and they are used in `get-address-info-by-cep.ts`'s +retry loop. Left on the namespace form, same as `http.request`. + +### `[...s]` has two different types depending on which checker you ask + +One more thing worth recording precisely, because it looked at first like a valid migration and +is not: `docs/semantics.md` §7.1 says `[...s]` is `str.codePoints(s)`, and the *engine's own* +checker treats the two as producing identical Core (`tests/idioms.spec.ts`). But `Ascii`/`Digits` +are ambient aliases for `string` (`engine/prelude/index.d.ts`), so *real* `tsc` infers `[...s]` as +`string[]` — an array of one-character substrings — never as `number[]`. `lib/format.ts`'s +`groupThousands` and `lib/json.ts`'s `jsonStringField` both treat the spread's elements as numeric +code points immediately afterward (arithmetic, comparison against numeric constants), so migrating +either would type-check under the engine's checker and fail under real `tsc` +(`Argument of type 'string' is not assignable to parameter of type 'number'`). Both call sites keep +`str.codePoints`, with a comment explaining why, and both are confirmed clean under +`tsc --noEmit -p core/tsconfig.json`. The idiom is sound only where a spread's elements go on to be +used as strings, not as numbers — this codebase has no such site. + +--- + +## The new step: proving the source runs + +`conformance/run-source.ts` imports the migrated utilities directly — `import { isValidCpf } from +"../source/is-valid-cpf"`, no `tsc`, no `cli.ts build` — and calls them, in Node, against the same +vectors `conformance/cases.ts` already holds, run through `sloppy-imports.mjs` exactly as +`conformance/run.ts` is. Each result is compared against the published npm package (`src/`), the +same ground truth `run.ts` compares the reference interpreter against. It is wired into +`engine/scripts/verify.ts` as a new step, `conformance (source, no engine)`, after `conformance`. + +It runs, and asserts on, exactly: + +- **`isValidCpf`** — every case (1,519) runs for real and matches the published package. The step + fails if even one case falls back to the ambient-gap path: this utility has no known gap left, + so a regression here is real. +- **`isValidCnpj`** — every case (2,032) is attempted; 1,216 run for real and match, 816 hit the + documented `str.codeAtOpt` gap in `hasLetter` (confirmed by asserting the exact `ReferenceError` + that line throws, not just "something threw"). The step fails if the matched count reaches zero + (the runnable half broke) or if the blocked count reaches zero (the gap silently vanished or the + vectors stopped exercising it — either way, this file's claim about `isValidCnpj` would be stale + and needs updating along with the step). +- **Everything else is named and skipped, with a reason, in the same file**: `formatCurrency` + (`dec.*`), `generateCpf`/`generateCnpj` (`random.nextU32`), `getHolidays`/`isBusinessDay` + (`date.*`), `getAddressInfoByCep` (`http.request`/`task.race`, and it would need a live network + to compare against the published package regardless), and `formatCnpj` (`str.charAtOpt`, + unconditional on every call, as described above). + +A mismatch, an unexpected throw, or either count-shrinking condition fails the step and the +overall `verify.ts` run. + +--- + +## Did `core/out` move? + +No generated program logic did, in any of the four targets, in either idiom mode. After the +migration: `node ../engine/src/cli.ts build --project .` (idiomatic) and `--no-idioms` both +regenerate byte-identical `.ts`/`.py`/`.go`/`.rs` files and byte-identical `API.json`/`LOWERING.md`. + +`SOURCEMAP.json` in each of the four tracked output directories *does* differ — every entry is a +`{start, end}` byte offset into the (now differently spelled, differently commented) source file, +one of the "three review artifacts every target produces" (`backend/generate.ts`) for pointing a +reader from generated code back to its source span. It carries no executable meaning and is +unavoidable: any edit to the source text at all, including a comment-only change, shifts byte +offsets later in the same file.

That branch is closing, and one part of it is worth more than the code — the measurements that answer a question this engine never addressed, which is why generate source at all instead of shipping one binary core and binding to it. Two findings decide it, and only one is about speed. A tree-shakeable package cannot take a binary core: one utility as generated source was 509 bytes that disappear when unused, against 9,291 indivisible and asynchronous ones. Go's cost for cgo is cross compilation, static binaries and `CGO_ENABLED=0`, not its 58 ns. Neither is a preference between acceptable options. The finding that does not decide it is kept too, because it is the one that makes the position honest: for Python, Ruby, C# and Java a binding really is cheaper than generated source, and that document's first version got it wrong by measuring the bindings a script reaches for rather than the ones a package ships. So the answer is scoped — JavaScript and Go must have generated source on grounds unrelated to speed, and the other four are a choice this engine makes for readability and the absence of a runtime rather than for throughput. ADR 0012 records that, including what it costs: four emitters to maintain and each language's semantics encoded four times. The document carries a header saying the harness behind its numbers was retired with the branch, so they should be reproduced before anything rests on them.

The emitters used to walk the string code point by +code point in every language, which is right for Go and Java and terrible for Python and Ruby +(6.5 µs and 15.1 µs per call — 2.6× and 4.1× _slower_ than handwritten). Two rules fixed it, and +both are in this branch: + +- **Collapse `guard-shape` + `sanitize` into one anchored regex with capture groups.** The + character classes are written out code point by code point (`[\u0009\u000a…\u2000-\u200a…]`), so + the semantics stay exactly the spec's — `\s` would not — while the matching happens in C. The + digits come out of the capture groups, so there is no second pass over the string and no + intermediate allocation. +- **Read digits as bytes in the check digit loop** (`ord(char) - 48`, `getbyte(i) - 48`) instead of + `int(char)` / `to_i`, and unroll the verification instead of iterating positions with a closure. + +Python went 6485 → 1366 ns/op; Ruby 15051 → 2020.

Without it the call still costs only 42 ns rather than + 41, because .NET's transition is already cheap — this is the one runtime where the naive + version is fine. +- **Java** needs the `MethodHandle` to be `static final` and the off-heap buffer to come from + `Arena.global()`. With a shared arena and an instance handle the same call costs 84 ns more, + because the JIT cannot fold the downcall stub and pays a liveness check per call. + `Linker.Option.isTrivial()` itself is worth about 1 ns here. +- **Python and Ruby** need a real extension module. `ctypes` is 16× more expensive than a + CPython extension; Fiddle is 23× more expensive than a Ruby C extension. + +The corollary about batching still holds, and is now less interesting: amortising one crossing +over 1000 inputs helps the expensive boundaries and _hurts_ the cheap ones. Python's C +extension is 65 ns per call and 236 ns per call in batch, because packing the buffer in Python +costs more than the calls it saves. + +### 3. Binding quality varies by 300× between runtimes of the same technology + +Same `.wasm` file, same core, same machine: + +- wazero (pure Go): **104 ns** per call +- wasmtime gem (Rust native extension): **521 ns** +- wasmtime-py 48 (ctypes over the C API): **30 059 ns** + +wasmtime-py is not slow at running wasm; it is slow at _being called_, because every invocation +builds `Val` arrays through ctypes. Poking the linear memory through its raw pointer instead of +`Memory.write` only takes it from 38.0 µs to 32.4 µs — the cost is the call, not the copy. + +So "we ship a wasm core" is not one decision with one performance profile. It is a different +decision per package, and in Python today it means "and also batch everything". + +### 4. The off the shelf tool is slower than writing Python + +UniFFI is the tool everyone recommends for this (Mozilla ships Firefox features with it). Its +generated Python bindings cost **9064 ns per call — 3.7× slower than just implementing the +validator in Python**, and 17× slower than the same `.so` called through hand written ctypes. + +The generated call path explains it: `check_lower` validates the string, `lower` allocates a +`RustBuffer` and copies into it, a `_UniffiRustCallStatus` struct is built, the call goes through +ctypes, the status is checked, the result is lifted. Six Python level operations wrapped around +100 ns of work. Even `uniffi-batch` (a `Vec` in, a `Vec` out) lands at 6196 ns/op, +still slower than plain Python, because the sequence has to be serialised into a `RustBuffer`. + +UniFFI is built for coarse grained APIs — "sync this database", "decrypt this blob" — where a +microsecond of glue is irrelevant. Brazilian Utils is the opposite: a hundred tiny pure functions. + +### 5. The JS package would pay the most and gain the least, which settles it + +| | Generated source | Wasm core | +| -------------------------------------------- | --------------------------- | ----------------------------------------------------------------------- | +| `isValidCpf` single import bundle, minified | **509 bytes** | 9291 bytes (4344 gzipped) for the core with **one** utility | +| Tree shaking | per function, as today | none: the module is one indivisible blob | +| Bundling, Deno, Bun, browsers, edge runtimes | works everywhere, no config | needs a loader, async instantiation, and a bundler that handles `.wasm` | +| `sideEffects: false` and zero dependencies | preserved | gone | + +An 18× size increase for one function, no tree shaking, and asynchronous initialisation, in +exchange for 160 ns. The npm package's selling points are exactly what a wasm core takes away. + +Cold start, for the record: instantiating the 9 KB module costs 0.025 ms in Node, 3.5 ms in +Python, 3.8 ms in Ruby — fine for a server, not free for a CLI or a lambda. + +### 6. A binding is cheap; a binary is not + +Every number above is per call. The cost that decides the question is per release. + +Generated source ships as source: it is reviewed in the package's own repository, `git diff` +shows what changed, a stack trace points at a line, and there is no build matrix at all. A +shared core ships as an artifact per platform × arch per ecosystem, and needs a release +pipeline that produces them, a fallback for platforms nobody built, and an ABI that the +package and the artifact both agree on. + +Two ecosystems make that trade badly: + +- **JavaScript**, because of §5: no tree shaking, 18× the bytes, asynchronous startup. +- **Go**, because cgo costs cross compilation, static binaries and `CGO_ENABLED=0` builds — the + things a Go library is expected to keep — and buys 74 ns against the generated code. + +Four make it well, because they already ship native extensions as a matter of course: Python, +Ruby, C# and Java. There the speedup is 3.9× to 21×, and the pipeline is one their maintainers +have built before. + +### 7. Every handwritten port is already subtly wrong + +Look at the `valid` column. Over the same 1000 inputs, the handwritten arms disagree with the +spec: Python 333, Ruby 329, Go 334, against 337 for everything generated. + +These are not bugs I planted. I wrote each handwritten arm the way the language invites: +`cpf.strip()` in Python strips a different set from JavaScript's `trim()`; Ruby's `String#strip` +handles only ASCII whitespace plus NUL; Go's `strings.TrimSpace` is Unicode space separators, which +excludes `U+FEFF`. Three languages, three different answers, for a CPF a user pasted with an +invisible character in front of it. + +The generated arms all answer 337 because the character set came from the spec, not from the +standard library's idea of whitespace. **The reason to generate is correctness; the performance is +what makes it affordable.** + +--- + +## The tools, surveyed + +| Tool | What it does | Languages | Why it does or does not fit | +| -------------------------------------------------------------------------------- | ------------------------------------------- | ------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| [UniFFI](https://github.com/mozilla/uniffi-rs) | Rust → bindings, from proc macros | Kotlin, Swift, Python, Ruby; C#/Go third party | **Measured: 3.6× slower than plain Python.** No JS, no Erlang.

From fb60bca8d4d2d751ba855fc30c8cf364aa52c9c1 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 21 Sep 2026 22:16:01 +0000 Subject: [PATCH 32/42] feat(engine): `xs[i] ?? fallback` is the author asking for the absent case MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The frontend chose between the unchecked and the checked accessor by provability alone: `xs[i]` became `seq.get` when the index was proven in range and `seq.at` when it was not. That rule is why three call sites in `core/source` had to keep the engine's spelling — there the index *is* provable, but the author wants the `Option` anyway, and the bracket spelling would have quietly selected the unchecked accessor and changed the Core. Provability is the wrong signal on its own. In TypeScript under `noUncheckedIndexedAccess`, `xs[i]` is `T | undefined` whatever the compiler can prove, and someone writing `xs[i] ?? fallback` has said in the language's own terms that the absent case is wanted. So the `??` decides: it selects the checked accessor unconditionally, and a bare `xs[i]` keeps the old rule. That unblocks what had no ordinary spelling. `formatCnpj` goes from running none of its cases to all 160 — `formatWithPattern` reached a checked accessor on every call, so it was not partially runnable, it was not runnable at all. `isValidCnpj` goes from 1216 of 2032 to 1627. `isValidCpf` stays at 1519 of 1519. The three call sites that carried a comment explaining why they could not move are now written the ordinary way, with the comment explaining why the `??` is load-bearing rather than decorative. Generated output does not move: the entire diff is the four `SOURCEMAP.json` files, whose byte offsets follow the source text. Conformance holds at 4256/4256 per target in both idiom modes.

So `?? fallback` is the author's statement in the language's own terms, not a claim about provability. Deciding it by provability instead would mean the same source text lowering to a different Core depending on a fact about the value that the author cannot see from where they are standing — which is the kind of surprise this whole frontier exists to remove. Also records `s[i]?.charCodeAt(0)` as the checked numeric accessor, since `s.charCodeAt(i)` answers `NaN` past the end rather than `undefined` and so has no `??` form of its own, and brings `core/docs/idiomatic-migration.md` up to date with what now runs.

It is accepted now, with the range inferred rather than demanded, from the two places the author already wrote it. A helper takes its contract from **its call sites**: the checker already specializes one per call site, which is how `digitAt` is checked against an eleven-digit CPF and a fourteen-digit CNPJ today, so a `number` parameter there simply starts at the platform-safe default and the caller's proven type is substituted in. Nothing new was needed. An exported utility has no call site, so it takes its contract from **a guard in its own body**. Every read of the parameter outside a guard's own condition is tracked, and the union of what was proven at those reads becomes the published type. The distinction matters: a guard's condition proves nothing about a use that has not happened yet, only its result narrows anything. What is left is an exported function that guards nothing, and that is refused rather than assumed or silently degraded: E_BARE_NUMBER: `n` is a bare `number`, and `isPositive` never narrows it before using it help: add a guard before n is used, for example `if (n < 0 || n > 99) return …;` — the range a guard like that proves becomes n's published contract; write `n: Int` instead if the full range really is what is meant Five annotations in `core/source` were only ever a way around the old ban and are gone. The thirty-eight that remain are contract: `year: IntRange<1900, 2099>` is real-world knowledge no guard in that body states, and `Digits` and `Ascii` refine a string rather than a number. Re-running the twelve probes found two claims in `subset-gaps.md` that were wrong. Method call syntax no longer needs a recognizer — that landed earlier. And an optional parameter is not refused at all: `params()` never reads the `?`, so `suffix?: string` is silently taken as a required `string`, which is a mistranslation rather than a gap, and worse than one. Both corrected there.

charset=UTF-8 Content-Transfer-Encoding: 8bit The benchmark's bar moved from 1.5x to 1.0x — generated code equal to or faster than the implementation each community ships by hand. Three shapes accounted for the rows above it, and each got its own answer. **A candidate nobody wrote.** TypeScript's `getHolidays` spent 78% of its call in `civilDate`, computing a date and then verifying it by a round trip through three floor-division helpers, while the host has `new Date` right there. The first attempt used `Date.UTC` and measured *slower* than the round trip it replaced — object construction costs more than the arithmetic — so what shipped is a days-in-month check and a single forward computation. 1.77x to 0.93x, and `isBusinessDay` follows it down to 0.66x. **Per-call overhead, with a budget declared per target.** A small pure function in a loop is free in V8 and in LLVM and expensive in CPython, so inlining is a cost decision per target like every other choice here: Python aggressive at twelve statements, TypeScript conservative at six — budget one was tried first and barely moved, which is itself the evidence that V8 was not the bottleneck at that layer — and Rust none at all, because the inliner has no notion of a borrow and spliced an owned local where ADR 0010 had removed the clone. **Allocation per step.** `str.concatAll` assembles a chain into one buffer instead of a fresh string per link, and `re.retain` and the code-point conversions work on ASCII bytes rather than decoding UTF-8. Ten of twenty-seven rows are still above 1.0x and each is recorded with why, because a row that cannot beat a hand-written implementation for a structural reason is a finding rather than an omission. Python's `formatCurrency` is an author's explicit character loop against one C-level formatter; its generators are a rejection-sampling loop run nine to twelve times against a single `randint`. Rust's remaining cost is spread thin across the scanner, the mask trim and one allocation, with no dominant term left — `#[inline]` hints were tried, measured to change nothing over six runs, and reverted rather than kept on faith. TypeScript's inlining costs bytes and the number is here rather than buried: the generated tree grows 20%, from 156,322 to 187,760, partly offset by `lib/random.ts` disappearing and `std/date.ts` shrinking. The package is tree-shakeable and that is a trade to state. A checkpoint during this work caught a real bug it had introduced: a double-evaluated capacity computation inside `str.concatAll` corrupted the draw sequence, and `rust-plain` produced a perfectly valid CPF that was not the one the reference produced. It compiled, it linted, the document validated, and only the differential comparison against the interpreter saw it. Fixed, and the whole suite re-run.

The round trip exists to answer exactly one question, "is +`day` within the month `month` names", and a days-in-month table (28-31, February adjusted for a +leap year) answers it directly, without decomposing anything back out: once the coarse bounds hold +(year 1-9999, month 1-12, day ≥ 1), `day > daysInMonth(month, year)` is the whole check, computed +without touching the calendar math at all. The candidate that replaced the round trip +(`engine/src/targets/typescript/index.ts`) is that check plus the single forward computation -- +one Hinnant function, not four. + +**What was tried and measured slower, and kept in this account rather than quietly dropped.** The +task's own framing named `new Date(year, month - 1, day)` as the obvious native candidate, since +that is what the handwritten side calls. It was implemented first -- `Date.UTC` to construct, +reading the result back through the UTC getters to detect a silently-rolled-over date, the same +round-trip *shape* the portable calendar already used, just against V8's calendar instead of four +Hinnant functions -- and measured directly against the portable round trip in isolation (2.4 +million calls each): the portable round trip took 366-390 ms; the `Date`-based candidate took +574-608 ms, **slower**, because `Date` object construction plus three getter reads costs more than +the arithmetic it was meant to replace. The days-in-month table has no such cost (63-81 ms for the +same 2.4 million calls, a 4.5-6x improvement over the round trip) because it touches no host object +at all. The `Date`-based candidate was removed rather than kept as a fallback; every claim in this +document is a measurement of the actual candidate shipped, not of the first thing that seemed like +it should work. + +The candidate is one expression for a "cheap" (name or literal) argument and an IIFE binding each +argument once for anything else, so an argument with a real cost is never evaluated twice; a +literal call site (`civilDate(year, 1, 1)`, `getHolidays`' own shape) always takes the cheap path. + +### Per-target inlining, measured per target + +`randomDigit(env) → randomBelow(10, env) → env.nextU32()` is a three-layer call chain, run nine to +twelve times per `generateCpf`/`generateCnpj` call, in every language that has it (TypeScript, +Python, Rust). Whether that chain's overhead disappears once it is hot is a property of the target, +not of the program -- V8 elides a monomorphic closure once it is hot, CPython pays a full stack +frame per call with nothing to elide it, and rustc/LLVM inline within a crate when they judge it +worthwhile, which for a bounds-checked call inside a loop was measured not to reliably include this +shape. `engine/src/optimize/inline.ts` is a Core-to-Core pass -- target-independent by construction, +the same layer `optimize/optimize.ts`'s constant-folding and dead-code passes live in -- but it runs +once per target, from `generate` (`backend/generate.ts`), with a budget (`InlineBudget.maxStatements`) +each `Backend` declares for itself. An eligible callee (no `Fail`, no `Http`, no direct or indirect +recursion, no lambda in its body, a statement count at or under the budget) gets its parameters +bound once each to fresh names, its body renamed so two splices of the same callee never collide, +and every `return` turned into an assignment to a synthetic `Option` result -- `break`ing the loop +it is directly inside where there is one -- so the whole thing prints as ordinary statements ending +in `opt.unwrap(result)`, using intrinsics (`opt.isNone`/`opt.unwrap`) every target already lowers on +its own. Multiple rounds let an inlined callee's own call (inlining `randomDigit` exposes its call +to `randomBelow`) get a chance in a later round. + +- **Python: aggressive, budget 12.** `randomBelow`'s own body (a bounded rejection-sampling loop) is + six statements; `cpf_check_digit`/`is_repeated` are five each, and fall under the same budget + incidentally -- there is no way to size a budget that reaches `randomBelow` without also reaching + them, since they are the same size. `generateCpf` moved from 1.86x to 1.65x, `generateCnpj` from + 1.99x to 1.89x. `generate_cpf.py`'s body is now one long flattened function instead of a chain of + small ones; Python was not weighed against a bundle-size budget the way TypeScript was below, so + 12 stayed the number. +- **TypeScript: conservative, budget 6 -- measured against 1 first.** A budget of 1 (inlining only + `randomDigit`'s single-`return` body, never reaching `randomBelow`'s loop) left `generateCpf` at + 1.14-1.18x and `generateCnpj` at 1.18-1.25x across three runs -- barely different from the + 1.44x/1.24x this pass started from, which is itself evidence the JIT was not the limiting factor + for the one layer it *was* inlining. A budget of 6 (large enough for `randomBelow`'s own body) + reached 1.06x/1.10x. **Bundle-size effect, measured, not hidden**: at budget 6, `generate-cpf.ts` + grew from 45 to 408 lines (1796 to 14695 bytes) and `generate-cnpj.ts` from 55 to 519 lines (1959 + to 18305 bytes); the whole `core/out/typescript` tree grew from 156322 to 187760 bytes, +20%, + partly offset by `lib/random.ts` disappearing entirely (nothing calls it once everything that did + has it spliced in) and by `std/date.ts` shrinking from the `date.fromYmd` fix above. This is a + real speed win paid for in bytes, for two rows that were already close to 1.0x before the pass and + stayed close after -- stated because the task asked for it stated, not because the trade is free. +- **Rust: none, deliberately, and the reason is itself a finding.** A first attempt at budget 6 + measured code that was *worse*, not better. This pass has no notion of a Rust borrow + ([ADR 0010](../../engine/docs/decisions/0010-rust-parameters-borrow-where-sound.md)) -- it binds + every inlined parameter as an owned local (`let name = argExpr;`), so a splice of a callee whose + parameter ADR 0010 had proven could borrow its argument printed a `.to_owned()` at that binding + instead: one full string clone per digit drawn, in `is_valid_cpf` and everywhere else the same + shape appeared. That is exactly the allocation ADR 0010 exists to remove, and it cost more than + the call overhead this pass would have saved, so `inlineBudget` is deliberately absent from + `RUST_BACKEND` (`engine/src/targets/rust/index.ts` carries the same account at the call site). A + smaller ask -- an `#[inline]` attribute hint on small non-exported functions, asking rustc's own + inliner to look rather than manually splicing anything -- was tried next and measured to change + nothing: `isValidCpf` came back at 22-25 ms with the hint present or absent across six runs, + indistinguishable from run-to-run noise, meaning rustc was already making the same inlining + decision either way. That was reverted too, rather than kept as a change with no measured effect + behind it. Closing this gap for Rust means teaching the pass to reconstruct ADR 0010's borrow + analysis for an inlined splice, not extending the budget -- future work, not this pass. +- **Go: not attempted.** Every Go row using this call shape (`generateCpf`, `generateCnpj`) was + already at or under 1.0x before this pass; `formatCurrency`, Go's one over-budget row, was closed + by the allocation fix below without touching call structure at all. + +### Allocation: one buffer or one pass, not a chain + +**Rust's string assembly.** A `+` chain (`a + b + c`) lowers as nested `str.concat` calls, +`concat2(concat2(a, b), c)`, and each `concat2` allocates a fresh `String` and copies everything to +its left into it -- `format_currency`'s `prefix`/`sign`/`body` assembly and every `concat2` in +`random_cpf_base`'s nine-digit chain were exactly this shape. `backend/lower.ts`'s `operation` now +flattens a chain of three or more pieces into its leaves before lowering (`(a + b) + c` is +`str.concat(str.concat(a, b), c)` in Core; the leaves are `[a, b, c]`, left to right, evaluated in +that order either way) and hands them to a new op, `str.concatAll`, when a target declares a +candidate for it -- Rust only, today; every target without one falls straight through to the +unchanged pairwise `str.concat` path, so nothing changed for TypeScript, Python or Go. Rust's +`str.concatAll` sizes one buffer once, from every piece's own length summed, and pushes each piece +into it once. Two correctness details worth naming because a first version of this got both wrong: +a piece whose length has to be computed (anything that is not already a name or a literal, most +often a call like `group_thousands(keep_digits(&whole))`) is bound to a local first, so it is +computed once, not twice -- once for sizing the buffer, once for pushing it, which the first version +of this candidate did not do, and which a differential run caught (`generateCpf`/`generateCnpj` +producing a well-formed but wrong document -- a different draw count changes which digits come out, +and every digit is still individually valid, so nothing but the reference interpreter's own answer +catches it); and a single-character literal piece prints `.push('x')`, not `.push_str("x")`, which +`clippy::single_char_add_str` (default warn) asks for. `generateCpf` moved from 2.37x to 1.68x and +`generateCnpj` from 1.89x to 1.22x; `formatCurrency` from 1.81x to 1.74x (smaller, because its own +remaining cost is elsewhere -- see the Rust section below). + +**`re.retain` and `codePoints`/`fromCodePoints`, in three languages.** `keep_digits`/ +`keep_alphanumeric` (`re.retain`) walked the input as decoded Unicode scalars -- +`.chars().filter(...)` in Rust, `strings.Map` in Go, `[ord(c) for c in whole]` in Python -- before +ever testing one against a range. Every class this project retains is ASCII (digits, upper and +lower case letters), and an ASCII byte needs no decoding to be tested: a multi-byte scalar's bytes +are all ≥ 0x80, so each one fails an ASCII range test on its own, exactly as testing the decoded +scalar would have failed it -- a byte-wise scan is not an approximation of the scalar-wise one, it +is the same predicate for less work, sound for any input, ASCII or not. Rust +(`String::from_utf8(value.bytes().filter(...).collect::>())`) and Go (a `[]byte` scan +building a `[]byte` result) both got this candidate, gated on every retained range being ≤ 127 (a +class outside that range, none exist in this project today, still falls back to the scalar-wise +pass). `str.codePoints`/`str.fromCodePoints` (`group_thousands`' `out: IntRange<0,127>[]`, proven +ASCII by its own declared type) got the matching treatment in Python (`.encode("ascii")` / +`bytes(...).decode("ascii")`) and Go (`[]byte(value)` / one `string()` from a `[]byte`), gated the +same way -- on the *element* type's range for `fromCodePoints`, since that op takes a list of code +points, not a string. `trunc_mod`/`trunc_div` (Python's truncated remainder/division, needed +because `%`/`//` floor in Python but the Core's contract rounds toward zero) were Python-level +functions called on every `%`/`//` whose operands were not provably non-negative -- a real cost in +CPython, where a function call is a full frame, not the arithmetic itself -- so both now print +their own formula inline as a single expression (a tuple evaluates both operands into fixed names +once, unconditionally, before the ternary that uses them picks a branch, so an operand that is +itself a call is still evaluated exactly once). Together these moved Python's `formatCurrency` from +2.91x to 2.66x and Go's from 1.08x to 0.93x -- Go's crossed 1.0x; Python's did not, and the +"Remaining over 1.0x" note below says why. + +### Remaining over 1.0x, and why + +**Python: `formatCurrency` (2.66x), `generateCpf` (1.65x), `generateCnpj` (1.89x).** +`group_thousands`' own loop -- `for index in range(0, len(scalars)): ... out.append(...)` -- is +still a Python-level loop with a method call (`list.append`) every iteration; removing `trunc_mod`'s +call and switching to bytes removed real overhead (2.91x → 2.66x) but did not remove the loop +itself, which is where most of what is left lives. Nothing in `engine/src/targets/python/**` can +turn an author's explicit per-character loop into a single C-level format call without either +recognizing that specific algorithm's shape (which this project treats as out of bounds -- a +candidate is for an *operation*, never a pattern-match on one author's algorithm) or rewriting +`group_thousands` itself, which is `core/source/lib/format.ts`, out of scope for this pass. The +generators' remaining gap is `random_cpf_base`/`random_cnpj_base`'s draw chain: even with the whole +`random_digit → random_below → next_u32` chain inlined (above), each draw is still a rejection- +sampling loop plus an `Optional[int]` bookkeeping the inlining introduced, run nine to twelve times, +against one `randint()` call on the handwritten side. Closing the remaining gap would mean either a +larger inlining budget (tried at the whole-chain size already; `cpf_check_digit`/`is_repeated` are +already incidentally included) or a structural change to how the draw itself works, both outside +what a lowering-only pass can do. + +**Rust: `isValidCpf` (2.57x), `formatCurrency` (1.74x), `generateCpf` (1.68x).** `isValidCpf`'s +`keep_digits` no longer decodes UTF-8 (above), and `cpf_check_digit`'s loop no longer clones (ADR +0010, already landed before this pass); `#[inline]` on `digit_at` was tried and measured to change +nothing (above), meaning the remaining ~2.5x is not a missed-inlining question. What is left is +spread across `re_match_3` (the CPF pattern's own scanner), the mask-character `trim_matches` every +`isValidCpf`/`isValidCnpj` call pays before `keep_digits` ever runs, and `keep_digits`' own +`String::from_utf8` allocation -- none individually dominant the way `.chars()` or the cloning loop +once were, which is itself the finding: the easy, single-cause wins are gone, and what remains is +distributed across several small, already-minimal operations, the last of which is a systems +language with an 11-character allocation and a bounds-checked scan against a handwritten crate +doing the same in roughly a third of the calls. `formatCurrency`'s remaining cost is +`group_thousands`/`keep_digits` themselves (now byte-based, but still O(n) passes CPython -- no, +Rust -- still pays for) plus `pad_start`'s own allocation, none of them a chain anymore. +`generateCpf`'s remaining 1.68x is the same rejection-sampling-loop-times-nine-to-twelve shape +Python's is, minus Python's per-call frame cost -- `next_u32()` itself is cheap in Rust, so what is +left is the loop and the `Option`/`Vec` bookkeeping around each draw, not a single hot line. +None of these three rows moved to a worse state than before this pass; all three are measurably +better than they were, and none reached 1.0x, which is reported here rather than left unexplained. + ## Rust `core/bench/rust/` compares the generated crate against `brazilian_utils`.

The trade is real: `generate_cpf.py`'s body is now one long flattened + function rather than a chain of four-line helpers, and Python has no bundle-size constraint to + weigh that against, so the budget stayed at 12. +- **TypeScript: conservative (budget 6), measured against a larger one.** V8 already inlines a + small monomorphic call once it is hot; a budget of 1 (inlining only `randomDigit`'s single-`return` + body, not `randomBelow`'s rejection-sampling loop) left `generateCpf`/`generateCnpj` at 1.14x-1.25x + — barely moved, confirming the JIT was not the bottleneck by itself. A budget of 6 (`randomBelow`'s + own size) reached 1.06x/1.10x. **Bundle-size effect, measured**: `generate-cpf.ts` grew from 45 to + 408 lines (1796 to 14695 bytes) and `generate-cnpj.ts` from 55 to 519 lines (1959 to 18305 bytes); + the whole `core/out/typescript` tree grew from 156322 to 187760 bytes (+20%), partly offset by + `lib/random.ts` disappearing entirely (everything that called it now has it spliced in) and by + `std/date.ts` shrinking from the `date.fromYmd` fix above. This is the trade the task asked to be + stated, not hidden: a real speed win, paid for in bytes, for a row that was already close to 1.0x + before the pass and stayed close after. +- **Rust: none, and the reason is itself a finding.** A first attempt at budget 6 measured *worse* + code, not better: this pass has no notion of a Rust borrow (`docs/decisions/0010-*.md`) — it binds + every inlined parameter as an owned local, so an inlined call to a function that ADR 0010 had + proven could borrow its argument instead printed a `.to_owned()` at every splice, one full string + clone per digit. That is exactly the allocation ADR 0010 exists to avoid, and by more than the + call overhead this pass would have removed, so `inlineBudget` is deliberately absent from + `RUST_BACKEND` (`engine/src/targets/rust/index.ts`'s own comment there has the same account). A + follow-up `#[inline]` attribute hint (a much smaller ask: let rustc's own inliner decide) was + tried and measured to change nothing (`isValidCpf`: 22-25ms with or without it, indistinguishable + from run-to-run noise) — rustc was already making the same decision either way — so that was + reverted too rather than kept as an unproven change. +- **Go: not attempted.** Every Go row was already at or under 1.0x before this pass except + `formatCurrency`, which the allocation fix below closed without touching call structure. + +**Allocation.** Two shapes, one in Rust, one in three languages at once: + +- `re.retain` (`keep_digits`, `keep_alphanumeric`) walked `.chars()`/`strings.Map`/ + `[ord(c) for c in whole]`-style, decoding the whole input as Unicode scalars before ever testing + one. Every class this project retains is ASCII (digits, upper and lower case letters), and an + ASCII byte needs no decoding to be range-tested — a multi-byte scalar's bytes are all ≥ 0x80, so + each one fails an ASCII range test on its own exactly as the decoded scalar would have, meaning a + byte-wise scan is not an approximation, it is the same predicate for less work. Rust + (`String::from_utf8(bytes().filter(...).collect())`) and Go (a `[]byte` scan) both got this + candidate, gated on every retained range being ≤ 127; a non-ASCII-range class (none exist in this + project today) still falls back to the scalar-wise pass. Python's and Go's `str.codePoints`/ + `str.fromCodePoints` (`group_thousands`' `out` list, proven `IntRange<0,127>` by its own source + type) got the same treatment for the same reason. +- Rust's string assembly built a `+` chain (`a + b + c`) as nested `str.concat` calls, each + allocating and copying everything to its left — `format_currency`'s `prefix`/`sign`/`body` + assembly and every `concat2` in `random_cpf_base`'s nine-digit chain were exactly this. + `backend/lower.ts`'s `operation` now flattens a chain of three or more pieces into their leaves + before lowering, and hands them to a new `str.concatAll` op when a target declares one (Rust + only, today; every other target falls through to the unchanged pairwise path). Rust's + `str.concatAll` sizes one buffer once, from every piece's own length, and pushes each piece into + it — with each length-costing piece bound to a local first, so a piece that is itself a call + (`group_thousands(keep_digits(&whole))`) runs once, not twice for sizing and pushing both; a + single-character literal piece prints `.push('x')`, not `.push_str("x")`, for + `clippy::single_char_add_str`. That is the architecture behaving as designed: performance was recovered by changing what the -compiler emits, not by rewriting a utility. +compiler emits, not by rewriting a utility. Conformance stayed 4256/4256 in every target, in both +idiom modes, throughout every fix in this section; `node engine/scripts/fuzz.ts fast` and `full` +both stayed clean. ### 9.

The inlining budget had no notion of that: it sized the callee and never priced the copy. Measured the way a consumer's bundler would (one single-import entry point per utility, esbuild, minified, gzipped) it cost +75% across every export and +148% on generateCnpj alone, for two benchmark rows it moved by about a tenth each -- inside the noise of a generator whose own retry loop is random. - `InlineBudget.maxDuplicatedNodes` caps what one inline may add. A splice that takes a callee's last call site is refunded its whole definition, which falls out of the dependency closure, so a sole-call-site helper is absorbed whatever its size and `0` means "take the inlines that pay for themselves". - A callee that is one `return ` is substituted as an expression, and a straight-line callee is spliced without the early-return sentinel; a parameter passed a literal or a local is substituted rather than bound. - A read the checker proved to be one integer is printed as that integer, which turns a specialized helper's arithmetic into constants; the bindings and parameters that leaves unread are removed, since Go and Rust reject both. - `backend/fold.ts` folds the lowered target AST, where a lowering's own expansion of a now-constant argument lives, and TypeScript's `date.fromYmd` folds a literal month directly. - `writeFiles` removes generated files a later run stopped producing. Two stale files were in the repository, typechecked and committed as though they were output. - A generated module now exports whatever another generated module imports: a surviving specialization is not the declaration it came from and carried that flag as false. Every export is now smaller than with inlining disabled (3,175 bytes gzipped across all nine, against 3,224 off and 5,644 under the old budget), Go's generators moved 0.57x/0.44x to 0.39x/0.32x, and the generated TypeScript reads like its source again. `engine/scripts/size.ts` measures it and `verify`'s new `typescript size` step holds it there. ADR 0013 has the reasoning, and `core/bench/README.md` the numbers. verify 17/17; conformance 4256/4256 on all four targets in both idiom modes, interpreter vs npm 4247/4247; fuzz full --seed 555 --count 200 clean.

The cause was not one thing, so each of these was timed on a scratch crate built against the generated one before being written as a candidate: - `re.retain` builds its result with a `for` loop into one `String` instead of `.filter().collect::>()` handed to a UTF-8 validator that re-walks it. Every byte pushed is already a range-tested ASCII byte. 11.4-12.3ms to 5.4-7.1ms per 200k calls. - `re_take_fixed`/`re_take_class` test the leading byte directly and decode a full `char` only above 0x7F. These two are the whole of every generated chain-pattern scanner, so this speeds up every regex-shaped validator the engine will ever emit, not just the rows that motivated it. 6.7ms to 4.4ms. - `str.padStart`, gated on both the value and the pad being proven ASCII, where a scalar count is a byte count and neither `Vec` is needed. 22.8-24.2ms to 10.4-10.5ms. This is most of `formatCurrency`'s move. - `str.codePoints`/`str.fromCodePoints`, ASCII-gated, mirroring what Go already had and Rust was missing. - `str.fromInt` for a value the checker proved is one decimal digit: one ASCII byte, not the general integer formatter. Measured over three runs, generated over handwritten: isValidCpf 2.73x -> 1.44x isValidCnpj 1.43x -> 0.96x, now faster than the crate it compares against formatCurrency 1.81x -> 1.05x generateCpf 1.66x -> 1.51x generateCnpj 1.22x -> 1.15x Two results that are not speedups, kept because they are worth knowing. An `unsafe from_utf8_unchecked` variant of `keep_digits` measured 5.4-5.6ms against the safe loop's 5.4-5.5ms, so the generated code stays `unsafe`-free for a measured reason rather than a stylistic one. And the first version of the `str.fromInt` candidate returned a `raw` text fragment, which stringifies its argument immediately and so hid a list literal from `hoistConstantTables`: a weight table that had been a module-level `const` silently became a `vec![]` allocated per call. Conformance did not catch it, since the answers were identical; `cargo clippy`'s `useless_vec` did. The candidate now builds a structured `call` node like the others. The remaining generator gap is the per-digit `String` allocation, which is roughly 40% of each draw. Removing it needs a return type that is not owned, which ADR 0009/0010 deliberately declined, so it is recorded rather than worked around. verify 17/17; the other three targets' output is byte-identical.

Its window makes locally repeated text almost free, so an encoding can be meaningfully shorter raw and larger gzipped — measured, not hypothetical: replacing nine unrolled concatenations with a counted loop removed 66 minified bytes from `generateCpf` and added 19 gzipped ones, because what it removed was near-perfect redundancy that LZ77 was already compressing for nothing. So the harness reports three numbers and gates two. `minified` is what the browser parses and the engine holds; it is not a transfer size, and trading it against one is an argument to have rather than a threshold to trip, so it is reported only. `gzip` and `brotli` are both transfer sizes and they disagree about which source is smaller, and a consumer gets whichever their CDN negotiates, so both are gated at zero growth. Brotli is measured at quality 11 with a size hint, since the streaming defaults would understate what a CDN serving a static asset produces.

The finding: `randomCpfBase` builds its result from nine textually identical `randomDigit()` calls, and a candidate lowering can re-roll N structurally identical pieces of a concat chain into one counted loop. It is sound (the call still runs N times, in order, so the draw sequence the conformance protocol fixes is untouched), it is faster (both generator rows go from noisy around 1.0x to 0.68-0.91x), and it removes 66 and 112 minified bytes. It was still declined, because both transfer encodings grow: +19/+23 gzip and +19/+19 brotli, +17 on the combined bundle under either. The reason is worth the space it takes, because the next idea for shrinking generated TypeScript by removing repeated call text will hit the same wall: text repeated eight or eleven times is nearly free to an LZ77-family coder, which spends a short back-reference per repetition instead of the literal bytes, while the loop that replaces it is shorter but unique and has nothing to point at. Brotli was measured specifically to test whether this was a gzip artifact. It is not; both codecs agree on direction. The botch: the two sections added in the previous two commits were spliced into the middle of a sentence in the intro, because the marker they were inserted before also occurs inside backticks there and the edit replaced every occurrence rather than the heading. Seven thousand characters of duplicated section have been removed and the sentence restored. Each section now appears exactly once.

It is also, on its own, +close to *free* to an LZ77-family compressor: gzip's DEFLATE and brotli's own LZ77 stage both +encode a repeated substring as a short back-reference (a length and a distance) instead of its +literal bytes, so text repeated eight or eleven times costs only a few compressed bits *per +repetition*, however long the substring or however verbose the file looks on disk. The loop that +replaces it — `let t=new Array(9);for(let r=0;r<9;r++)t[r]=48+s(e);return String.fromCharCode(...t)` +— is short, but it is short, *unique*, once-occurring text: there is nothing in it for a +back-reference to point at. Trading eight-or-eleven-times-repeated text for shorter unique text is +a net loss under both codecs even though it is an unambiguous win raw, because the repeated text's +compressed cost was already close to nothing and the unique text's is not. + +**Both variants, measured.** `node engine/scripts/size.ts core` (now — see the note at the end of +this section — reporting and gating gzip *and* brotli, both at maximum quality) on the committed +baseline against the loop variant, minified / gzip / brotli, every export: + +| export | minified (base → loop) | gzip (base → loop) | brotli (base → loop) | +| --- | ---: | ---: | ---: | +| `formatCnpj` | 518 → 518 | 334 → 334 | 292 → 292 | +| `formatCurrency` | 434 → 434 | 312 → 312 | 267 → 267 | +| `generateCnpj` | 1,301 → **1,189 (−112)** | 629 → **652 (+23)** | 549 → **568 (+19)** | +| `generateCpf` | 1,284 → **1,218 (−66)** | 614 → **633 (+19)** | 532 → **551 (+19)** | +| `getAddressInfoByCep` | 2,855 → 2,855 | 1,277 → 1,277 | 1,149 → 1,149 | +| `getHolidays` | 2,379 → 2,379 | 817 → 817 | 765 → 765 | +| `isBusinessDay` | 2,922 → 2,922 | 1,022 → 1,022 | 966 → 966 | +| `isValidCnpj` | 1,481 → 1,481 | 499 → 499 | 452 → 452 | +| `isValidCpf` | 760 → 760 | 333 → 332 (−1) | 290 → 291 (+1) | +| `(all)` | 9,839 → **9,661 (−178)** | 3,175 → **3,192 (+17)** | 2,891 → **2,908 (+17)** | + +`generateCpf` and `generateCnpj` are the only rows that move, at every metric, confirmed at the +bundle level (not just by diffing the generated files — the `(all)` bundle, which puts both +functions' now-similar loop bodies in the same file where they could in principle compress against +each other, still grows by the same +17 both codecs agree on). `isValidCpf`'s ∓1 is noise, not a +third affected row: `isValidCpf` never calls `randomCpfBase` (it imports only `cpfCheckDigit`, +`cpfCheckDigit1` and `isRepeated` from the same source file), its *minified* byte count is +identical in both variants, and gzip and brotli move it in opposite directions by one byte each — +consistent with esbuild's minifier assigning a different short name to some unrelated binding +because an unrelated part of the same source file changed, not with any real content difference. + +Speed, `core/bench/typescript.ts`, generated ÷ handwritten, three runs each: + +| row | baseline (unrolled) | loop variant | +| --- | --- | --- | +| `generateCpf` | 0.92x – 1.31x (noisy, often over budget) | **0.80x – 0.91x** | +| `generateCnpj` | 1.19x – 1.31x (always over budget) | **0.68x – 0.85x** | + +The loop variant is not a marginal win — both rows go from noisy-around-or-over-1.0x to solidly +under it, every run, and it is faster than a simpler variant tried first (unrolled +`String.fromCharCode(48 + randomBelow(env), 48 + randomBelow(env), …)` in place of the +`.toString()`-and-`+` chain, same number of calls, no loop: 0.88x–0.93x / 0.90x–0.96x, +9/+9 gzip, +smaller than the loop's own +19/+23 but not zero either). + +**Why brotli, and why it agrees.** gzip's window is 32 KiB and it has no notion of "text that looks +like other text commonly seen on the web" — its preference for local redundancy could plausibly be +a gzip-specific quirk rather than a real property of what a browser downloads. Brotli has a larger +window and a static dictionary seeded from common web content, and it is what most CDNs actually +negotiate today, so it was measured specifically to test whether gzip's verdict was an artifact. +It was not: brotli (quality 11, with `BROTLI_PARAM_SIZE_HINT` set — the default quality +understates this, since it is tuned for streaming, not a static asset) grows on both rows and on +the combined bundle, by an amount close to gzip's own (`generateCpf` +19 under both codecs; +`generateCnpj` +23 gzip vs. +19 brotli — brotli's dictionary helps a little here, not enough to +flip the sign; `(all)` +17 under both). Two independent general-purpose compressors, tuned to their +respective maximums, agree on the direction. That is the basis for the decision below, not one +codec's number. + +**The decision.** This is a real, reproducible, substantial speedup — both over-budget rows move +solidly under 1.0x — declined on a stated constraint: this file's bar is 1.0x on speed, but +`engine/scripts/size.ts --check`'s bar is zero gzip *and* zero brotli growth on every export, and +this change fails both by nine to twenty-three bytes depending on the row and the codec. The engine +change (`engine/src/backend/lower.ts`'s `sameExpr`/`asAsciiDigitConversion`/`loopConcat` plus a +`TargetSpec.loopUnroll` flag, `engine/src/targets/typescript/index.ts`'s `loopUnroll: true`) was +built, measured on both codecs, and reverted rather than shipped past the gate; `core/out/typescript` +in this repository is the unrolled baseline, unchanged. If the trade above — solidly-faster +generators for 9–23 bytes of gzip/brotli growth on two exports, nothing else affected — is one +worth taking, that is a call for a human to make explicitly (with `size.ts --write`, after it +accepts the new numbers as the baseline), not one this pass makes on its own. + +`engine/scripts/size.ts` reports and gates gzip *and* brotli as of this writing (both at maximum +quality, both required not to grow); a reader checking the numbers above against a future run +should confirm the tool still measures both before comparing directly, since this section's numbers +are a snapshot of one measurement rather than something `verify` re-derives on every run. + ## Getting every row to 1.0x The pass this section documents took the budget from "within 1.5x" to "equal or faster,
