The egress addon now selects each request's Config by the calling bottle's
source IP, so one shared sidecar serves every bottle. Opt-in and fail-closed;
single-tenant behaviour is unchanged.
Orchestrator side (source-IP-primary attribution, per the PRD invariant):
* registry: `by_source_ip` (the single active bottle at a source IP —
network-layer attribution); `attribute` now composes it + the token.
* service: `resolve(source_ip, token="")` — with a token, strict
attribution; without, source IP alone.
* control_plane: `POST /resolve`'s identity_token is now OPTIONAL (absent
→ source-IP-only); split cleanly from the token-required `/attribute`.
* policy_resolver: `resolve` token now optional.
Egress side:
* egress_addon_core: `resolve_client_config(resolver, client_ip, token)` —
fetches + parses the client's Config, **fail-closed**: unattributed, a
resolver error, or an unparseable policy all yield deny-all (no routes).
Host-testable; `PolicyResolverLike` Protocol keeps it import-free.
* egress_addon: consolidated mode when `BOT_BOTTLE_ORCHESTRATOR_URL` is
set → `_active_config(flow)` resolves per client IP (reads + strips the
`x-bot-bottle-identity` header); `request()` uses it. Unset → the static
routes file, exactly as before. `PolicyResolver` added to the bundle.
Security note: source-IP-only resolution is safe where the IP is unspoofable
(Firecracker /31 + nft) AND the control plane is reachable only by the
trusted sidecar; the identity token, when the agent injects it, strengthens
it on weaker backends.
Scope note: the egress data plane is now multi-tenant. Remaining to be fully
live: the network topology routing every bottle's proxy to the one shared
sidecar, git-gate multitenancy, and agent-side identity-token injection.
Tests: registry by_source_ip; orchestrator resolve (with/without token);
control-plane /resolve token-optional; resolver token-optional;
resolve_client_config fail-closed matrix. All 182 egress tests still pass
(single-tenant unchanged). Full suite green.
