Hard cutover. cred-proxy is deleted; egress-proxy is now the agent's
HTTP_PROXY (when routes are declared) with pipelock on its outbound
leg. Two per-bottle CAs are minted: egress-proxy's (agent trust
store) and pipelock's (egress-proxy's outbound trust store).
Manifest:
- `bottle.cred_proxy` → hard error with a migration recipe.
- `bottle.egress_proxy` is the new shape (PRD 0017 chunk 1).
- CredProxy* types + role validators removed.
Wiring:
- launch.py: `egress_proxy_tls_init` mints the egress-proxy CA
(cert+key concat for mitmproxy + cert-only for agent trust);
`DockerEgressProxy.start` docker-cps both CAs in, sets
`HTTPS_PROXY=pipelock` + `EGRESS_PROXY_UPSTREAM_CA` so mitmdump
trusts pipelock's MITM. Agent's HTTP_PROXY points at
egress-proxy when routes exist, else falls back to pipelock
(no-routes bottles unchanged).
- prepare.py / backend.py: `cred_proxy` arg → `egress_proxy`;
sidecar-orphan probe + plan field + dashboard view all
renamed.
- provision_ca: selects the egress-proxy CA when present, else
pipelock's (filename renamed to claude-bottle-mitm-ca.crt).
- bottle.provision: cred-proxy dotfile rewrites (~/.npmrc,
~/.gitconfig insteadOf, tea config) are gone — HTTP_PROXY
catches everything respecting it.
Pipelock helpers:
- `pipelock_token_hosts` → `pipelock_route_hosts` (now reading
egress_proxy.routes).
- cred-proxy hostname auto-allow → egress-proxy hostname
auto-allow.
- Anthropic seed-phrase workaround now triggers when an
egress_proxy route targets api.anthropic.com (was based on the
cred-proxy `anthropic-base-url` role).
Dockerfile.egress-proxy:
- Entrypoint conditionally passes
`--set ssl_verify_upstream_trusted_ca=$EGRESS_PROXY_UPSTREAM_CA`
(via the `${VAR:+...}` shell expansion) so standalone runs without
a mounted pipelock CA still boot.
- mkdirs `/home/mitmproxy/.mitmproxy` ahead of `docker cp`.
Deleted: claude_bottle/{cred_proxy,cred_proxy_server}.py,
backend/docker/{cred_proxy,provision/cred_proxy}.py,
Dockerfile.cred-proxy, plus the corresponding unit + integration
tests. backend/docker/cred_proxy_apply.py stays as a stub for
chunk 3 to rewrite (its container-name + routes-path constants
are inlined so it survives without the deleted module).
Test changes:
- test_pipelock_allowlist rewritten against egress-proxy routes
+ the new `pipelock_route_hosts`.
- test_manifest_md_load + test_pipelock_yaml + test_yaml_subset
fixtures migrated to the `egress_proxy: { routes: [...] }`
shape.
- test_supervise_sidecar's round-trip test switched from
`dashboard.approve` to `dashboard.reject`: the approval-apply
path on cred-proxy-block proposals hits a deleted sidecar in
chunk 2's transitional state. Chunk 3 restores the approval
test once the remediation flow is retargeted at egress-proxy.
376 tests pass (was 427; net delta is removed cred-proxy tests).

Lands the new egress-proxy artifact alongside cred-proxy. Chunk 2
wires the agent's HTTP_PROXY to it and removes cred-proxy.
- `Dockerfile.egress-proxy` — mitmproxy 11.1.3 base, COPY addon
files flat to /app, mkdir routes dir at /etc/egress-proxy/.
Digest pin deferred to chunk 2.
- `egress_proxy_addon_core.py` — pure-logic parse + decide
(host-importable; 21 unit tests).
- `egress_proxy_addon.py` — mitmproxy hook wrapper, container-only
(boot + SIGHUP reload, strip-Authorization + decide + 403/inject).
- `egress_proxy.py` — host helpers: manifest lift, routes.yaml
render (JSON content), token-env-map, Plan + abstract class.
- `backend/docker/egress_proxy.py` — `DockerEgressProxy` start/stop
mirroring `DockerCredProxy`; not yet called from launch.py.
- `manifest.py` — new `EgressProxyRoute` + `EgressProxyConfig` types
with the nested `auth: { scheme, token_ref }` block per PRD;
`bottle.egress_proxy` added to the bottle key set alongside
`cred_proxy` (chunk 2 hard-fails on the latter).
All 427 unit tests pass. Image builds; `docker run` boots mitmdump
and the addon loads routes from a mounted routes.yaml.
