- engine::guide's route rule ends "and nowhere else": the service's instructions join every rule on one line, where the old ending and the signing-key rule read together as a comparison to the prose check. - test.sh makes a relative WAI_QUANTUM absolute before it changes to the project's directory, and smoke.sh runs the binary by an absolute path: CI gives it ./target/release/wai-quantum.

wai-quantum: the editors' support in the READMEs, the changelog and the smoke checks
The command line's README gains an Editors section (what the language server brings, `wai-quantum fmt`, where the extension, the other editors' configurations and the grammar are, and a client configuration of one's own); the engine's README names `engine::editor` with the rest of the engine; wai/CHANGELOG.md records the whole of it. smoke.sh checks that fmt gives the one layout, that --check tells formatted from not, that a program whose brace is not closed is refused with its line, and that the server answers initialize and exits cleanly after shutdown. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai-quantum-editors.yml: the editors' support, in CI
On linux: the language service's tests (each module shown to have run), the language server's scripted session over standard input and output and its unit tests, the grammar regenerated with the pinned command line and held identical to the committed parser, its corpus and highlighting, every program in the repository parsed with no error, `wai-quantum fmt` on each of those programs (stable on a second pass, and drawn by the engine as the original is, or refused alike), the editor extension packaged and checked with the built command line, and the WebAssembly extension built for wasm32-wasip2. On macos: the language service's tests and the server's session. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai/tools/wai-quantum-editor: the editor extension, and configurations for other editors
The extension highlights OpenQASM (a TextMate grammar) and starts `wai-quantum lsp` (path, extra arguments, generator inputs and shots in its settings). Its lenses and palette commands run Run, Plan, Critique, Shortcuts and Receipt through the server, and each answer goes to an output panel; a receipt can be saved as JSON. When the command line is missing it says so, with the install commands of the command line's README, and offers the setting for its path. It builds to one bundled file and packages to a .vsix with the pinned packaging tool; it is not published. editors/ holds a configuration for three kinds of editor: one configured in Lua (the server through the built-in configuration or the lspconfig plugin, the grammar through the tree-sitter plugin, and a command for each of the server's commands), one configured by languages.toml (the server, the formatter and the grammar, with its queries in that editor's capture names), and one with WebAssembly extensions described by extension.toml (a small extension that finds and starts the server, built for wasm32-wasip2; every locked crate is at least two weeks old). test/check.mjs (79 checks) holds the manifest to the server's commands, the highlighting token by token, the missing-binary message to the README, every configuration to its syntax and to the server and the grammar, the query copies to the grammar's, and the package to exactly the extension's files. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai/tools/tree-sitter-openqasm: OpenQASM 3 as a tree-sitter grammar
The grammar reads every statement of OpenQASM 3.1 (declarations of every type, gates, subroutines and externs, modifiers and gphase, control flow, timing, calibrations kept as text with their braces matched, pragmas and annotations) and OpenQASM 2's qreg, creg, opaque, measure q -> c and if(c==1). The parser is generated at ABI 14 with the pinned command line (0.26.13) and committed; regenerating it reproduces it byte for byte. Queries for highlighting, scopes and folds; 17 corpus tests checked tree for tree, and the highlighting checked by 15 assertions. script/check-programs.mjs parses every program in the repository's conformance material and examples (the tracked .qasm files, the Studio's worked examples, the language service's samples, the programs in the command line's README and smoke script): 25 of 25 parse with no error, and a broken program is refused, so a clean result means something. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai-quantum: the language service and server for editors, and fmt
The engine gains `engine::editor`, the language service an editor needs, pure and with no protocol in it: - diagnostics: the reader's refusal on its line (one mapping function, `reader_diagnostic`, where stable codes and exact spans plug in), and the critique's smells on theirs, with their kind as the code; a generator is read at the given inputs, or 4; - completion of keywords, the standard gates (with parameter placeholders), and the registers, gates, subroutines and variables in scope, by what the cursor's place takes; snippets, and sample programs in an empty file; - hover: each standard gate's matrix written exactly, held entry by entry to the engine's own matrix under all 46 names the reader accepts; a user gate's matrix from the engine's matrices of its gates; each gate's cost as the engine counts it (two-qubit gates, T count, depth), at the call's angles or at generic ones, said which; a register's size; - definition, references, highlights and rename over an index of declarations and scopes that reads the whole of OpenQASM 3, and a half-typed program; symbols, folding (blocks, comments, held blocks); - a formatter with one layout, refusing a program whose brackets do not match, checked to keep every token, and tested stable and meaning-preserving (the engine reads the formatted program to the same circuit) on a corpus in every part of the language; - lenses for Run, Plan, Critique, Shortcuts and Receipt. The command line gains two verbs. `wai-quantum lsp` serves it over standard input and output, UTF-16 or UTF-8 positions as agreed, the commands run in-process on a thread of their own and signed with the user's key; `wai-quantum fmt` formats, `--check`s and `--write`s. tests/lsp.rs drives the binary through a scripted session from initialize to exit.

- engine::guide: the route rule allows a quantum provider the person added themselves, only for a run they ask for, and the Agent Skill says how (dry run, cost, the person's yes). - The stdio MCP server's tools() now includes the provider tools, so tools/list, the generated llms.txt, llms-full.txt, the AGENTS.md block and the skill's tool reference list the same tools. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai: the open provider protocol, and Bring your own quantum
- extensions/quantum-providers.md: wai.quantum.provider/1, its two transports, its messages and error codes, the program in a device's own gates with exact angles, the six operations, the bit order, the cost and confirmation rules, what the receipt proves and what it does not, the conformance vectors and the reference provider. - wai-quantum-qpu/bring-your-own-quantum.md: what is free, adding a provider of each kind with its credential in the keychain, running on it from the command line, an agent and the desktop, the reference as a template, the receipt, and what a person does to connect a real device. - The READMEs of wai-quantum-qpu, the command line, the engine and the job service (which never routes to a provider or takes a credential), and the CHANGELOG. Co-Authored-By: Claude Opus 5.5 <[email protected]>
Quantum Studio and the desktop app: Your hardware, with a cost dialog
- Desktop: providers_list, provider_estimate and run_on_provider commands; the app reads the credential from the keychain, seals the counts with the user's key, and refuses a run that is not free unless the page confirms it. - Studio: a "Your hardware" switch. In the desktop app it lists the person's providers, asks for the estimate first and shows a dialog before a run that is not free; in a browser tab it says such runs go through the desktop app or the command line, since a tab must not hold a provider's credential. - Tests: test/hardware.test.mjs (the switch's logic without a browser), a check in the browser test, and a desktop test of the estimate, the refusal and the sealed run. The Studio workflow runs the first and pins the last, and follows wai-quantum-qpu. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai-quantum CLI: providers verbs, run --provider, and three MCP tools
- providers add|list|remove|describe|test|free|reference: the person's own providers in their registry, a credential read from standard input (never a command line) into the keychain, or named by an environment variable; describe and the conformance test; what anyone can use free; and the reference provider served by this binary, as a template. - run --provider NAME [--dry-run] [--yes]: the plan with the exact native compile, its check and the provider's estimate; a run that is not free refused (exit 3) until --yes; the counts sealed with this user's key, checked by verify. - MCP: providers_list, provider_estimate and run_on_provider; the last says it can spend the person's money and refuses without confirm_cost: true when the run is not free. - A `providers` feature (default) carries it, so the WASI build without default features stays as it was. CI: the command line's workflow follows wai-quantum-qpu and pins the five end-to-end tests by name. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai-quantum-qpu: bring your own quantum (open provider protocol, reference, registry, jobs)
- open_provider: the open provider protocol, wai.quantum.provider/1, over HTTP (curl, a credential only over https or to this machine) or a local process (one JSON line each way, the credential in its environment); a program travels in the device's gates with every angle an exact dyadic fraction of a turn, and its OpenQASM 3 beside it. - reference: the protocol around the exact simulator, served both ways (wai-qpu reference --stdio | --http ADDR): the provider the tests run against, and the template to copy. Free, or priced per shot or job in exact decimals; polls, readout error and a credential checked by hash. - conformance: the checker and its vectors (conformance/provider-v1.json), with the reference's counts pinned; jobs run only when free or allowed. - registry: the person's list in their configuration directory, holding no credential; credentials in the keychain (the system security tool, or secret-tool), else a 0600 file, and every listing says which. - job: the dry run (exact native compile, the check by simulation, the provider's estimate and billing unit), the refusal of a run that is not free until it is confirmed, and the seal of its counts by the engine. - Provider gains details, estimate, a seeded submit and cancel, with defaults, so the three built-in clients keep working unchanged. CI: the QPU workflow pins the three test binaries' counts and the new tests by name, and a macOS leg runs the keychain test in its own keychain file. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai-quantum engine: a job on the person's own provider, read, compared and sealed
engine::provider says what a provider job may ask (counts of a program whose measurements come at the end and whose angles are dyadic, so it compiles exactly to a device's gates), turns the device's counts into a result labelled measured with the circuit's exact distribution beside them (total variation distance, Hellinger fidelity, and what the shots alone would leave), and seals it so job::verify checks it. catalog::read refuses a request that names a provider, so a host that reaches none (the job service) never runs one on its own methods.

wai-quantum-py-release.yml builds the abi3 wheels on a wai-quantum-cli-v* tag and attaches each with its SHA-256 to that forge release, as the command line archives are (release/publish.sh, over the private network): macOS arm64 and x86_64 (cross-built on the Apple-silicon runner), Linux x86_64 and arm64 as manylinux2014 (maturin with zig 0.16.0, so the runner glibc does not leak into the wheel; checked: the module needs GLIBC_2.17 at most), and Windows x86_64. Each wheel that runs on its runner is installed alone on Python 3.9 and runs tests/smoke.py first. Nothing is published to a package index. The changelog entry (wai/CHANGELOG.md), the crate README naming engine::svg and the package, and ci/check.sh waiting on the service it stops so the shell prints no job notice. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai-quantum engine::svg: every mark keeps its colour without the style sheet
A page that strips <style> from what it shows (a notebook sanitising an untrusted output) would leave unstyled lines with no stroke and the background rectangle filled black. Each line and path now carries a stroke in the text colour, each text and dot a fill, each box, ring and meter an outline with no fill, the background none and each key swatch its hand colour; the style sheet still overrides them all. A sixth test checks every element of a drawing for its attribute. The doc notebooks are written again with the new drawing, and ci/check.sh expands an empty array the way the bash macOS ships accepts under set -u. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai-quantum-py: WAI Quantum in Python and notebooks, in-process
A new crate, wai/wai-quantum-py, built by maturin 1.15.0 into one abi3 wheel per platform (pyo3 0.29.3, Python 3.9 on), module wai_quantum. Its extension module wraps the shared job engine and nothing else: run, plan, lint, draw (text and the engine SVG), layout, critique, improve, shortcuts, equivalent, verify, seal, canonical, digest, methods, accuracy_classes and history, values crossing one to one with JSON (NaN, integers past 64 bits and non-string keys refused). A job is the service form as a plain dict with helpers (counts, probabilities, expectations, amplitudes, method, accuracy, receipt); Key reads and writes the command line key files and finds the same user key; bloch gives each qubit reduced state from the engine expectation values. A refusal raises EngineError with the engine message, its line, and a code slot for the engine diagnostic codes. Service is a client in the standard library alone for the job service (submit, status, result, cancel, run), naming itself wai-quantum-python/<version>, its receipts checked here offline. Widgets (the widgets extra): Circuit (the engine drawing, gates clickable, authorship marks from a history), Result, Receipt (the engine verdict) and Bloch (drag to turn), each a plain ES module, each with static HTML (and SVG) fallbacks that render without the widget library. Five doc notebooks run in CI and are held to their stored outputs. ci/check.sh is the whole check; 62 pytest tests hold the package to the command line (same results, plans, lints, critiques, drawings, methods, equivalence verdicts; receipts verified both ways; the same user key; the digest recomputed from Python canonical bytes), to the service run locally, and run the front ends under node on the payloads; Python 3.9 smoke with the wheel alone. Workflow wai-quantum-py.yml runs it on linux and macos. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai-quantum engine: a circuit as a standalone SVG drawing (engine::svg)
The drawing the Studio makes from the layout, written once in the engine for hosts with no page of their own (a notebook, a report, a file): the same classes and geometry, a style sheet of its own scoped to .wq-circuit that follows the text colour it is placed in, every number written to two decimals so the same program writes the same bytes everywhere. Given whose hand each operation is in, each gate is marked with its author and a key under the drawing counts them; a condition legend and a note past 400 columns. Five tests: the Bell pair glyph by glyph, every layout item drawn and the bytes repeatable, the authorship marks and key, escaping and number writing, and the column cap.
