From 70f773ac6106adfed8a820a357eb64248dc27037 Mon Sep 17 00:00:00 2001 From: didericis Date: Mon, 25 May 2026 14:30:39 -0400 Subject: [PATCH] feat(egress-proxy): cutover from cred-proxy (PRD 0017 chunk 2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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).
