Overview
Experimental RFC 9180 HPKE envelope provider for @absolutejs/e2ee, using the WebCrypto-backed primitives in hpke.
This 0.x package has not been independently audited by AbsoluteJS. It provides isolated single-recipient envelopes, not MLS or a secure messaging protocol.
The initial suite is DHKEM(P-256, HKDF-SHA256), HKDF-SHA256, and AES-128-GCM for broad WebCrypto runtime support. The suite and wire version are explicit and authenticated context is supplied as both HPKE info and AEAD additional data.

Production guidance
Make every external boundary explicitPin the deployed @absolutejs/e2ee-webcrypto version, replace example or memory-backed dependencies with durable implementations, bound external calls, protect credentials, and emit enough evidence to retry or recover safely.

Trace from the first failed boundary
Reproduce the smallest canonical @absolutejs/e2ee-webcrypto example, confirm the supported entry point and version in the API explorer, then inspect the first boundary that did not produce its documented result.
