Context

Step 2 of #63 (backend: JavaScript). Step 1 (#602, PR #606) landed docs/design/JAVASCRIPT-BACKEND.md; its section 6 names this as slice 1 of the implementation: the smallest slice that runs a real program under Node.

What

js: run a first conformance program under Node. Add Architecture.JavaScript to std/core and TargetArchitecture.JavaScript to project/target.trb, so that browser-js is a BuildTarget (everyTarget(), targetNamed, the tables of docs/tooling/torb-build.md); create compiler/src/backend/javascript/{emit,body,type,natives,writer}.trb and runtime/javascript/{core,int64}.mjs; emit the constructs of the slice-1 row of section 6 with the dispatch loop (Integer, Boolean, Void, records and tuples, Constant, Move, Copy, Branch, Jump, Return, Panic, TextConcat, PrintParts, ExitWithCode), the text of section 2.5 and the Int helpers of JAVASCRIPT-AND-PHP.md section 2a; make torb build, torb run and torb check accept the target without --emit-c; add tests/conformance/javascript_first.trb with its .expected and .exit files, tests/conformance/js.allow, tools/conformance.sh --js and the CI job conformance-js that installs Node 24.21.0 through .forgejo/actions/node.

Seed: touches it by name (a new Architecture case and target the build looks up), so expect two commits: the case of Architecture and the target first, the back end after; confirm with tools/check-commits.sh.

Out of scope: anything in the rows of slices 2 to 8 of section 6, a minifier, a source map, torb test. No slice adds a native to the kernel.

Acceptance criteria

torb build --target browser-js builds tests/conformance/javascript_first.trb (integers of every width with an overflow that panics, functions and recursion, a struct, print of text and numbers) and the output runs under Node
javascript_first.trb passes on the C, the VM and the JavaScript legs with the same expected files
js.allow holds it and the existing programs that use only the slice-1 constructs
CI job conformance-js with Node 24.21.0 runs tools/conformance.sh --js
torb format --check and torb docs check are green

Dependencies

Depends on #602 (closed, design record landed)

Part of the epic #63; the record docs/design/JAVASCRIPT-BACKEND.md section 6 is the specification.

## Context Step 2 of #63 (backend: JavaScript). Step 1 (#602, PR #606) landed `docs/design/JAVASCRIPT-BACKEND.md`; its section 6 names this as slice 1 of the implementation: the smallest slice that runs a real program under Node. ## What *js: run a first conformance program under Node.* Add `Architecture.JavaScript` to `std/core` and `TargetArchitecture.JavaScript` to `project/target.trb`, so that `browser-js` is a `BuildTarget` (`everyTarget()`, `targetNamed`, the tables of `docs/tooling/torb-build.md`); create `compiler/src/backend/javascript/{emit,body,type,natives,writer}.trb` and `runtime/javascript/{core,int64}.mjs`; emit the constructs of the slice-1 row of section 6 with the dispatch loop (`Integer`, `Boolean`, `Void`, records and tuples, `Constant`, `Move`, `Copy`, `Branch`, `Jump`, `Return`, `Panic`, `TextConcat`, `PrintParts`, `ExitWithCode`), the text of section 2.5 and the `Int` helpers of JAVASCRIPT-AND-PHP.md section 2a; make `torb build`, `torb run` and `torb check` accept the target without `--emit-c`; add `tests/conformance/javascript_first.trb` with its `.expected` and `.exit` files, `tests/conformance/js.allow`, `tools/conformance.sh --js` and the CI job `conformance-js` that installs Node 24.21.0 through `.forgejo/actions/node`. Seed: touches it by name (a new `Architecture` case and target the build looks up), so expect two commits: the case of `Architecture` and the target first, the back end after; confirm with `tools/check-commits.sh`. Out of scope: anything in the rows of slices 2 to 8 of section 6, a minifier, a source map, `torb test`. No slice adds a native to the kernel. ## Acceptance criteria - [ ] `torb build --target browser-js` builds `tests/conformance/javascript_first.trb` (integers of every width with an overflow that panics, functions and recursion, a struct, `print` of text and numbers) and the output runs under Node - [ ] `javascript_first.trb` passes on the C, the VM and the JavaScript legs with the same expected files - [ ] `js.allow` holds it and the existing programs that use only the slice-1 constructs - [ ] CI job `conformance-js` with Node 24.21.0 runs `tools/conformance.sh --js` - [ ] `torb format --check` and `torb docs check` are green ## Dependencies - Depends on #602 (closed, design record landed) _Part of the epic #63; the record `docs/design/JAVASCRIPT-BACKEND.md` section 6 is the specification._

[loop:torbscript] release implement: worker failed after 25 min (output overflow, no result); nothing pushed (no branch, no PR). Claim ended. next: respawn next tick with a narrower brief (keep the session output small; slice 1 only).

[loop:torbscript] release implement: PR #679 is open with CI green at head 13657e4a, and Argus is requested as reviewer. It has two commits: the browser-js target, and the emitter with runtime/javascript, the --js conformance mode and the conformance-js job. tests/conformance/javascript_first.trb ran under Node in CI and matched its expected output, including exit 101 and the panic position. Not exercised: torb run --target browser-js. Left for later slices: slices 2 to 8, the minifier, source maps and torb test on browser-js.
next: waiting (review of PR #679)
