Corpus programs are differential tests against Node: every program runs under Node and as a compiled native binary, and stdout, stderr, and exit codes must match byte-for-byte. A new feature lands with corpus programs that pin its behavior both ways.
Record a new or remeasured program's CI cost (used to balance the test shards) in `tests/harness/corpus-costs/<program>.json`, not in `tests/harness/corpus-costs.json`; see the README there.
Before opening a PR that adds or changes corpus, diagnostic, or frontend fixtures, run `pnpm test:ts7 --baselines-only`. This fast completeness check uses the same fixture discovery as the parity suite; it does not type-check or replace behavioral parity. Generate missing preflight/order baselines, review their diagnostics and module order, and run the affected `order-parity.test.ts` batches before pushing. Keep existing baseline entries unchanged unless the corresponding behavior intentionally changes. The full `pnpm test:ts7` command also checks completeness before starting its sweep.
A change that must not cost good code anything, such as a compatibility fix that replaces a refusal, proves it with the zero-cost gate. The gate compiles the benchmark workloads, the self-hosted compiler, and the TypeScript corpus with two built checkouts. It requires byte-identical IR, LLVM, and release executables, and compile time within tolerance. `--allow=<regex>` names the change's pattern signature: programs whose sources match may differ, and the PR lists them. Any other difference fails the gate, which names the first differing function. The gate also enforces the two-tier runtime separation: no executable may gain symbols from `DYNAMIC_TIER_PREFIXES` in `scripts/zero-cost-compare.mjs`, and fully typed benchmarks may link none; extend that list as dynamic-tier units land. `--quick` checks only the benchmarks; `--cachegrind` adds per-function instruction counts for executables that differ. Run it in a Sandbox with both checkouts prepared:

Some code compiles but can behave differently than under Node.js. Coverage reports the cases it can detect as `SC6xxx` warnings, and `scriptc build` prints the same warnings after a successful build. They never fail a build, but `--fail-on=divergences` can fail a CI job on them.
- `SC6001`: a record passed to, stored as, asserted as, or stored as an array element of a record type with different properties is copied, and the program then writes through the copy or compares it by identity.
- `SC6002`: an object literal's key order differs from its type's declaration order, and the program observes the order through `JSON.stringify`, `Object.keys`, `Object.values`, `Object.entries`, `for...in`, or console output.
- `SC6002`: values of one record type are built in different key orders, so the type keeps its declaration order, an object literal's key order differs from it, and the program observes the order through `JSON.stringify`, `Object.keys`, `Object.values`, `Object.entries`, `for...in`, or console output.
- `SC6003`: `localeCompare` compares a string literal outside the built-in Latin-script collation.
- `SC6004`: a call passes a class instance to a function that casts it to an unrelated class.
- `SC6005`: a `Date` string literal uses a form the native parser does not accept.

JavaScript Dates retain identity through checked storage and support Date-copy construction and JSON serialization.
A TypeScript Date converted to `unknown` becomes a Date with the same time value; each conversion creates a new Date, so two `unknown` values converted from one TypeScript Date are not `===`.

- **Timeouts:** when a test's `{ timeout }` elapses, its running subtests are cancelled, as in Node.
Subtests do not take their parent's `timeout` as their own, where Node's do, and the subtests of a timed-out test with `{ concurrency }` above 1 run to completion before the test reports.
A body that keeps running after its timeout and calls `t.test` again runs that subtest, where Node reports it as not started.
- **Thrown values:** a test that throws an object or array that is not an `Error`, such as `throw { code: 42 }`, reports `[object Object]` in the failing section, where Node prints the value as `util.inspect` renders it.
- **Test names:** a test without a name, or with an empty one, takes its function's name or `<anonymous>`, as in Node, when the function's name is known at compile time: a function expression, a function declaration, or a `const` bound to an arrow or anonymous function.
A name computed at run time, with a function the program received as a parameter, is used as given, so an empty one stays empty where Node uses the function's name.
`test(fn)` and `test("", fn)` with such a function throw `SC2020`.
- **Current context:** `getTestContext()` returns the context of the test, suite or hook whose code is running, as in Node: `undefined` at module top level, the root's context in module-level hooks, the suite's in a suite body and in the suite's hooks, and the test's in its body, in the code it awaits, and in the timers, immediates, `process.nextTick` and `queueMicrotask` callbacks it schedules.
Node returns, for a suite, a `TestContext` that is a different object from the `SuiteContext` passed to the suite body and its `before` and `after` hooks; in a compiled program they are the same object, so comparing them with `===` gives `true`.
Completion callbacks of callback-style I/O APIs, such as `fs.readFile`, get `undefined`, as AsyncLocalStorage stores do.

Local calendar getters use the operating system's timezone database.
Historical results can differ from Node.js when timezone data differs.
For valid extreme years outside a platform calendar API's range, scriptc uses a calendar-equivalent year in the 400-year Gregorian cycle to obtain the timezone rule.
`toString`, `toTimeString`, `String(date)` and template literals print the zone's long name after the GMT offset, as Node does (`GMT-0500 (Central Daylight Time)`). scriptc identifies the zone the way Node does, from `TZ` when it names a zone, else from `/etc/localtime`.
Outside Windows, a write to `process.env.TZ` changes the zone for later conversions and getters.
The names are the en-US names for the IANA zones; Node prints them in the language of the locale that `LC_ALL`, `LC_MESSAGES` or `LANG` selects, so with a non-English locale the name differs from Node's.
A `TZ` value that is a file path or a POSIX rule string (such as `EST5EDT,M3.2.0,M11.1.0`) gives offsets and names that differ from Node's, which ignores those forms.
On Windows, the name is the `GMT+hh:mm` form unless `TZ` names a zone.
On `wasm32-wasi`, local time is UTC and the name is `Coordinated Universal Time`.

Object spread of a class instance is refused.
Dense array literals created directly in checked storage preserve identity, and supported native handles pass by reference.
`Object.keys`, `Object.values`, `Object.entries`, and `JSON.stringify` use a record's declaration order rather than per-object insertion order.
Their order matches Node.js when objects are built in declaration order.
`SC6002` reports object literals whose order differs where the program observes it.
`Object.keys`, `Object.values`, `Object.entries`, `for...in`, `JSON.stringify`, and `util.inspect` enumerate a record's keys in one order per record type rather than per object. scriptc chooses that order from the order in which the program's object literals create the keys, follows object spread, rest destructuring, and record conversions back to the values they copy, and places an optional key that the program assigns after construction after the keys the object was built with.
The order matches Node.js when every value of the type is created in the same order.
When values of one record type are created in different orders, including values of two types with the same properties and property types, or when a key is deleted and assigned again, the type keeps the declaration order of its first type instead, and `SC6002` reports object literals whose order differs where the program observes it.
A record converted from a checked value, such as `const rows: { score: number }[] = JSON.parse(text)`, keeps the properties its type does not declare.
`JSON.stringify`, `Object.keys`, `Object.values`, `Object.entries`, `util.inspect`, and untyped views of the record see them, together with the declared fields, in the source object's key order.

Length, string methods and relational comparisons such as `<` and `>` use UTF-16 semantics, including for lone surrogates.
`split` with a string separator and `replace` or `replaceAll` with a string pattern don't match a lone surrogate against half of a surrogate pair; regular-expression patterns do.

* assertion of the global object keeps the checked-dynamic value itself: a
* view whose member reads and writes go to the global object, and bindings
* of it hold that object.
*
* Other checked-dynamic operands keep the checked extraction: a native value
