didericis 32b62cbacc feat(cred_proxy)!: cred-proxy is the only Anthropic auth path
test / unit (pull_request) Successful in 13s
test / integration (pull_request) Successful in 23s
Removes the legacy `CLAUDE_BOTTLE_OAUTH_TOKEN` -> `CLAUDE_CODE_OAUTH_TOKEN`
forward in prepare.py. Bottles that need claude-code to authenticate
must declare a cred_proxy route with role: "anthropic-base-url" — there
is no fallback that hands the token to the agent directly.

Drops the now-dead BottleSpec.forward_oauth_token field, the CLI
setter that read CLAUDE_BOTTLE_OAUTH_TOKEN from the host env at
prepare time, and the forward_oauth_token=False arg in the six
pipelock integration tests.

PRD 0010 and README updated; the dev ~/claude-bottle.json gains an
anthropic-base-url route so the implementer/researcher agents keep
working.

BREAKING: bottles previously relying on the implicit OAuth forward
will now produce an agent environ without any Anthropic credential.
Verified with --dry-run: a bottle with no anthropic-base-url route
yields env_names: [] (no token at all); a bottle that declares the
route yields ANTHROPIC_BASE_URL plus a non-secret placeholder for
CLAUDE_CODE_OAUTH_TOKEN.

didericis fcbbc4484d refactor(cred_proxy): flat routes, role-driven provisioning (PRD 0010)
test / unit (pull_request) Successful in 14s
test / integration (pull_request) Successful in 22s
Replace bottle.tokens (with Kind enum and hardcoded per-kind
route/auth tables) with bottle.cred_proxy.routes — each route
declares its own path, upstream, auth_scheme, token_ref, and
optional role[]. The manifest is now the source of truth for the
proxy's runtime route table; adding an upstream is a manifest edit,
not a code change.

Agent-side rewrites move from per-kind dispatch to per-role tags
on routes:
  anthropic-base-url -> set ANTHROPIC_BASE_URL=<proxy><path>
  npm-registry       -> write ~/.npmrc registry=
  git-insteadof      -> write ~/.gitconfig [url] insteadOf, keyed
                        off route.upstream (suppressed when
                        bottle.git brokers the same host)
  tea-login          -> add a ~/.config/tea/config.yml login

Roles are a list (string accepted as sugar). A gitea route
typically carries ["git-insteadof", "tea-login"]. Singleton roles
(anthropic-base-url, npm-registry) appear on at most one route.

token_env slots are assigned per distinct TokenRef in declaration
order — two routes sharing a token_ref (e.g. github API + git
endpoints) share a slot.

Drops: TOKEN_KINDS, _KIND_ROUTES, _KIND_AUTH_SCHEME, _TOKEN_DEFAULT_HOST,
cred_proxy_route_path_for_gitea, the kind field on CredProxyUpstream,
and the kind-based hardcoding in pipelock_token_hosts (now derives
from route.UpstreamHost).

Legacy bottle.tokens manifests now die with a hint pointing at
bottle.cred_proxy.routes + this PRD. Tests rewritten end-to-end.
Docs + example.json + the dev ~/claude-bottle.json updated to match.

didericis 27b2d78b11 fix(cred_proxy): close git-push bypass + route through pipelock (PRD 0010)
test / unit (pull_request) Successful in 15s
test / integration (pull_request) Successful in 29s
Three coupled fixes that close a documented bypass of git-gate's
gitleaks pre-receive hook:

1. cred-proxy refuses git smart-HTTP push at runtime. Any path
   ending in /git-receive-pack or /info/refs?service=git-receive-pack
   returns 403 with a pointer at the bottle.git SSH path. Fetch
   (upload-pack) is still allowed — the bypass we're closing is
   push, where gitleaks is the load-bearing scanner. Hard guarantee.

2. The provisioner suppresses the cred-proxy `~/.gitconfig` insteadOf
   rewrite for any host already declared in bottle.git. git-gate is
   the canonical git path there; we don't write a competing rule
   that would let `git clone https://<host>/...` succeed in ways
   that confuse on push. Defense in depth — (1) is the hard guarantee.

3. cred-proxy routes its outbound HTTPS through pipelock. The
   sidecar's environ now sets HTTPS_PROXY=<pipelock-url>, and the
   image's entrypoint runs `update-ca-certificates` over the
   per-bottle pipelock CA (docker cp'd into
   /usr/local/share/ca-certificates/pipelock.crt before start) so
   the proxy's HTTPS client trusts pipelock's bumped certs.

   Consequence: pipelock's allowlist + body scanner now sit in the
   cred-proxy egress path the same way they sit in front of direct
   agent traffic. The cred-proxy upstream hosts (api.github.com,
   github.com, gitea hosts, registry.npmjs.org) come OFF
   pipelock's passthrough_domains. Only api.anthropic.com remains
   on passthrough (LLM body content legitimately trips DLP).

PRD 0010 updated to reflect all three. Tests adjusted: the
"cred-proxy hosts go on passthrough" assertion in
test_pipelock_allowlist flips to "they don't", a new
TestIsGitPushRequest exercises the smart-HTTP refusal predicate,
and the gitconfig renderer tests cover the per-host suppression
matrix.

didericis c8ab90d01d fix(manifest): allow token + git on the same host (PRD 0010)
test / unit (pull_request) Successful in 13s
test / integration (pull_request) Successful in 22s
git-gate holds an SSH IdentityFile for push/fetch; cred-proxy holds
a PAT for HTTPS REST API calls. The two brokers are orthogonal —
the common dev setup names both on the same host (e.g. gitea.dideric.is
SSH for push, gitea.dideric.is PAT for `tea pr create`).

The original PRD 0010 wording called this a "configuration smell"
and rejected it at parse time. That was wrong; this drops the
overlap rejection from the validator and updates the PRD prose to
match. Tests flip from "rejection" to "coexistence" assertions.

didericis 9fa9717135 docs: switch cred-proxy to sidecar shape
test / unit (pull_request) Successful in 15s
test / integration (pull_request) Successful in 27s
Make the cred-proxy a per-bottle sidecar container on the bottle's
internal docker network instead of a root-owned process inside the
agent container. The boundary becomes container namespace
separation, matching pipelock and git-gate. Update summary,
problem, goals, in-scope, architecture diagram, components,
existing code touched, external deps, and open questions; add a
"Considered alternatives" section recording the rejected
in-container shape.

didericis 3747927b9e docs: align cred-proxy architecture diagram
Trim one trailing space from the four arrow/HTTPS rows and add
one dash to the bottle-container bottom edge so all box-bound
lines are 68 columns.

didericis 1411719973 docs: add PRD 0010 for credential proxy
Per-bottle reverse proxy that holds API tokens (Anthropic OAuth,
GitHub PAT, Gitea PAT, npm) in a root-owned process; agent gets
only URLs in its environ. AWS / SigV4 explicitly out of scope.
