Seal browser SDK 1.0.1

Candidate package; not yet published. Reports browser errors to /api/v1/ingest using X-API-Key, app_name, environment, error_type, error_message, stack_trace, code_context, and severity.

Seal.init({apiKey: 'BROWSER_PROJECT_KEY', appName: 'Frontend', environment: 'production'});

Use a dedicated browser project key; values embedded in browser code are public. Do not embed backend signing or encryption secrets. Global application error handlers are preserved.

The SDK does not evaluate downloaded JavaScript. Optional rescueEngine: true and an explicit onApprovedPatches(candidates) callback expose approved candidates to application-owned review/application logic. The callback must implement validation, application and rollback. The feed requires app/environment scope and returns an array with hash, patchCode, patch_id, and patch_version. Enabling the rescue setting alone does not execute code.

npm test verifies the contract and absence of automatic code execution. Publish only after backend scope/approval changes are deployed and the dedicated application pilot passes.
