sandbox: add SandboxAPI SDK module (preview/apply/receipt)#112yakimoto wants to merge 3 commits into
Conversation
WAVE go-live dogfood run (2026-09-02) found @wave-av/sdk has zero
sandbox surface: no SandboxAPI class, no CATALOG entry, nothing wired
into the Wave convenience class -- despite api.wave.online/v1/sandbox/*
being live in prod (verified: unauthenticated POST /v1/sandbox/preview
returns a well-formed 402 x402 quote).
Adds src/sandbox.ts (SandboxAPI: preview/apply/receipt/run), wires it
into Wave + the barrel export, and extends the export-parity tests
(sdk-exports.test.ts, 34->37 modules) plus a dedicated sandbox.test.ts.
Contract verified against wave-sandbox edge/core.mjs (origin/main):
preview returns {tier, wouldExec, fsDiff, receipt}; apply requires
approval = the preview receipt id and returns {approved, tier,
containment, exitCode, stdout, truncated, fsDiff, receipt}; receipt
GET returns {receipt}.
Gates: tsc --noEmit clean; vitest run 164/164 passed; eslint clean;
tsup build succeeds (dist/sandbox.* generated). dist/ not committed --
pre-existing drift on origin/main already has several src/*.ts modules
(agent-auth, automations, comms, inference, pricing, products, etc.)
with no matching committed dist output, so a --clean rebuild renames
every content-hashed chunk file; committing only the sandbox-relevant
subset would ship an inconsistent require graph. Flagged separately,
out of scope for this PR.

Reviewer's GuideIntroduces a typed SandboxAPI SDK module backed by the live sandbox preview/apply/receipt routes, exposes it through both package exports and Wave.sandbox, and verifies request forwarding, approval chaining, error behavior, and export parity. The PR intentionally does not update generated dist artifacts or address separate gateway API-spec/MCP and production scope/entitlement gaps.

WalkthroughThe SDK adds a typed ChangesSandbox API
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The SDK adds authenticated sandbox execution and receipt lookup, but receipt identifiers are not constrained before becoming request paths, which can redirect credential-bearing requests to unintended same-origin endpoints. Sandbox apply operations also inherit automatic retries without a confirmed replay-safe contract, so this PR is not merge-ready until the path handling and apply retry behavior are addressed or explicitly accepted by the owner.

💡 Quality: receipt() interpolates receiptId into URL path without encoding
receipt(receiptId) builds the request path as ${this.basePath}/receipt/${receiptId} without encodeURIComponent, unlike the established pattern elsewhere in this SDK (src/pricing.ts:59, src/transcripts.ts:41,47, src/inference.ts:80,89), all of which encode path-interpolated identifiers. If a caller passes a receiptId containing /, ?, or other reserved characters (e.g. forwarded from unsanitized user input), the request could hit an unintended path or query string instead of failing cleanly. Wrap the interpolation with encodeURIComponent(receiptId) for consistency and defense-in-depth.
Encode receiptId before interpolating it into the request path, matching the convention used in pricing.ts and transcripts.ts.:
async receipt(receiptId: string): Promise<SandboxReceiptResult> {
return this.client.get<SandboxReceiptResult>(`${this.basePath}/receipt/${encodeURIComponent(receiptId)}`);
}

Path Traversal (CWE-22): Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploitability: Moderate
Encode receiptId as one path segment before adding it to the request path.
An attacker-controlled receiptId can contain / or .. and target a different same-origin API path while retaining the client’s authentication headers. Use encodeURIComponent(receiptId).

User description
Live receipt that motivated the change
WAVE go-live dogfood run (2026-09-02), running the sandbox product end-to-end as a paying
customer would across four surfaces: human API key, MCP,
@wave-av/sdk, and theunauthenticated path.
POST https://api.wave.online/v1/sandbox/preview-> 402, well-formedx402 quote (
x402Version:1,accepts[0].scheme:"exact",network:"base",payTo,asset,session_id,next_action.type:"pay"). Confirms the route is live and armedin prod (not
ROUTE_NOT_MAPPED, not dark-by-construction perwave-gateway/test/sandbox-spoke.spec.ts's "dark when SANDBOX_ORIGIN unset" contract).POST /v1/sandbox/previewwith the WAVE dogfood key (Doppler secret nameWAVE_GATEWAY_API_KEY, prod config, value never printed) -> 403 SCOPE_INSUFFICIENT,
required_scope: sandbox:write. The key'savailable_scopeslist 47 scopes, includingsandbox:readbut notsandbox:write-- reported separately as an operator scope-grantgap, not fixed here (prod Supabase
api_keysrow mutation is an operator crossing, notsomething a build worker should run).
POST https://api.wave.online/mcp {"method":"tools/list"}-> 66 tools, zerocontain "sandbox". Root cause:
wave-gateway/src/mcp-product-tools.tsderives toolsfrom the intersection of
enforcedV1Groups()andopenapi-spec.generated.tsoperations,and
api-spec(origin/main) has zero/v1/sandbox/*operations defined. That's agap in
wave-av/api-spec, out of scope for this PR (would need real request/responseschemas plus a
wave-gatewayspec-SHA bump) -- flagged in the run report, not attemptedhere given the size of an accurate multi-repo spec change under this lane's turn budget.
@wave-av/sdkhas zero sandbox surface. NoSandboxAPIclass,no
sandboxfield on theWaveconvenience class, no entry in the vendoredproducts.tsCATALOG. A customer using the official SDK has no typed way to call a live, priced,documented-in-the-gateway product. This is the "SDK method missing" defect class named
explicitly in the run brief.
Root cause
@wave-av/sdkships 34 (now 37, after this PR) hand-written per-product API modules(
ClipsAPI,VoiceAPI,CaptionsAPI, ...), each wired individually into theWaveconvenience class in
src/index.tsand re-exported from the barrel. Sandbox shipped inwave-gateway/wave-sandboxwithout a corresponding SDK module ever being added -- thereis no automated parity check between the gateway's live route surface and the SDK's module
list (unlike the MCP tool generator, which is derived-only from
api-spec).What changed
src/sandbox.ts(new):SandboxAPIclass withpreview(),apply(),receipt(), and arun()convenience method (preview -> apply in one call, threadingreceipt.idthroughas the approval token). Types (
SandboxPreviewResult,SandboxApplyResult,SandboxReceiptResult,SandboxReceipt, etc.) modeled directly off the livewave-sandboxedge contract (edge/core.mjs, origin/main, read at the pinned SHA duringthis run):
preview->{tier, wouldExec, fsDiff, receipt};applyrequiresapproval= a prior preview'sreceipt.idand returns{approved, tier, containment, exitCode, stdout, truncated, fsDiff, receipt};GET /receipt/{id}->{receipt}.src/index.ts: import + exportSandboxAPI/createSandboxAPIand their types from thebarrel; add
public readonly sandbox: SandboxAPIto theWaveclass and instantiate itin the constructor -- same pattern as every existing module (
ClipsAPI,VoiceAPI, etc.).src/__tests__/sandbox.test.ts(new): 6 tests coveringpreview,apply(approval tokenforwarded verbatim),
receipt,run()(2-call preview->apply chain), aSCOPE_INSUFFICIENTrejection passthrough (documents the live 403 this run hit), and thefactory function.
src/__tests__/sdk-exports.test.ts: extended the existing export-parity suite (whichenumerates every module class/factory and asserts the
Waveclass wires all of them) toinclude
SandboxAPI/createSandboxAPI, bumping the expected count 36 -> 37.dist/is intentionally not touched in this PR.origin/main's committeddist/isalready stale relative to
src/(several existing modules --agent-auth,automations,comms,computer,custody,inference,mcp,pricing,products,runtime,transcripts,webhooks-- have source files with no matching committeddist/*output).Because
tsupcontent-hashes shared chunk filenames, a--cleanrebuild renumbers everychunk across the whole package; committing only the sandbox-relevant
dist/sandbox.*+dist/index.*subset while leaving 30+ otherdist/*.jsfiles pointing at now-stale chunkhashes would ship an inconsistent require graph. That's a pre-existing, separate gap
(dist/src drift) this run flags but does not fix -- the repo's own
prepublishOnlyscriptalready runs
npm run buildbefore any real publish, sodist/will be regeneratedcorrectly at release time regardless.
Proof (commands + output, secret values never printed)
Operator steps (not run by this lane -- reported per contract)
the
sandbox:writescope.wave-gateway/src/scopes.ts(origin/main) documents thatsandbox:writeis deliberately not inUNIFORM_CUSTOMER_SCOPESand must be anexplicit per-key grant in Supabase
api_keys.scopes(prod refgoqtrxgdmaqojmixradj)-- the same two-step pattern
wave-gateway/scripts/mint-staging-key.shuses forstaging (mint via RPC, then
PATCH /rest/v1/api_keys?id=eq.<key_id> {scopes:[...,"sandbox:write"]}), but against prod. This is a prod Supabase datamutation -- an operator crossing this lane will not run.

wave-gateway/src/catalog.tsEDGE_PRODUCT_SCOPES.sandbox) so the entitlement-mirrorgate (
