Completes the de-sidecar cleanup: no live code, test, current doc, script, or nix file mentions or is named "sidecar" any more. Only the dated PRD/research docs keep the term as historical record (agreed on the #385 thread). - Rename `sidecar_init.py`→`gateway_init.py` was done earlier; this pass sweeps the remaining descriptive uses: the egress / git-gate / supervise components are the gateway's *daemons*, the shared container is the *gateway*, the old per-bottle container was the *companion container*. - Rename `tests/integration/test_sidecar_bundle_image.py`→`test_gateway_image.py` and its class; update `docs/ci.md` + `tests/README.md` for the renamed/ removed integration tests. - `SIDECAR_PORTS` shell var in `scripts/firecracker-netpool.sh`→`GATEWAY_PORTS`. Full unit suite green (bar the pre-existing `/bin/sleep`-missing env errors in test_gateway_init); docker integration — gateway singleton, broker, real two-bottle multitenant isolation, and the gateway-image build — all pass.

"""Unit: EgressAddon request/response decision flow (issue #286).
|
|
|
|
`egress_addon.py` is the gateway-only mitmproxy adapter that wires the
|
|
host-importable decision logic in `egress_addon_core` into mitmproxy's
|
|
request/response hooks. The core logic is exercised directly by
|
|
`test_egress_addon_core.py`; the redaction logging by
|
|
`test_egress_addon_log_redaction.py`. This file covers the adapter glue
|
|
itself — `request()`, `response()`, `websocket_message()`, introspection,
|
|
auth injection, git push/fetch blocking and the outbound-DLP policy
|
|
branches — so `bot_bottle/egress_addon.py` no longer has to be omitted
|
|
from coverage.
|
|
|
|
mitmproxy is not installed on the host, so we pre-populate `sys.modules`
|
|
with the minimum stubs needed to import the adapter (a `mitmproxy.http`
|
|
module exposing a `Response` with `.make`, plus the flat
|
|
`egress_addon_core` name the gateway uses)."""
