This affects all libraries using the default agents: - **Axios <=1.18.0**: can double-proxy because both Axios and Node process `HTTP_PROXY`/`HTTPS_PROXY`. Workaround: set `NODE_USE_ENV_PROXY=0` so only Axios handles the proxy. -- **Axios >=1.18.1**: defers env proxy handling to Node. Works correctly with shellroute. +- **Axios >=1.18.1**: defers env proxy handling to Node, avoiding the known double-proxy conflict. Not tested with shellroute. - **Got**: default HTTP/1.1 path uses Node's global agent and routes correctly.

Applies to direct and interactive mode. P2: Node version claims corrected — supported on 24.0+ (fetch), 24.5+ (http/https), 22.21+ (backport). Node 20/21/23 unsupported. Node fetch default row replaced with NODE_USE_ENV_PROXY=0 opt-out. Axios wording unchanged (not tested). P2: Tests exercise production code and emitted shell scripts. Added: uppercase-only NO_PROXY, lowercase-only no_proxy, both-set union, deduplication, controller NO_PROXY union script in bash, controller NODE_USE_ENV_PROXY ownership in bash, /rotate DISCONNECTED cleanup.

Handles NO_PROXY=* and wildcard domains without bash glob expansion. Works in bash and zsh. Both NO_PROXY and no_proxy are unioned into one deduplicated list and assigned identically to both variables. P2: Shell scripts extracted to session.NoProxyUnionScript and session.NodeProxyOwnershipScript constants. Tests import and execute the production constants under both bash and zsh. Added: NO_PROXY=*, wildcard-domain, differing-lists, /rotate cleanup path. P2: Matrix metadata updated — version marked unreleased (post-0.1.0), date 2026-08-11. Node version ranges corrected: 22.0-22.20 and 24.0-24.4 explicitly listed as unsupported. Node fetch default replaced with NODE_USE_ENV_PROXY=0 in methodology.
