Consolidated egress ran every bottle through one process but keyed the supervise proposal queue off a single SUPERVISE_BOTTLE_SLUG env and kept one *global* DLP safelist — so in the shared gateway an operator's token approval for bottle A would (a) be attributed to the wrong bottle and (b) leak into bottle B's DLP scan (A's approved secret passes B's egress). This slice keys both per bottle, resolved by source IP. - policy_resolver: add `resolve_policy_and_bottle_id` — policy + bottle id in one `/resolve`, so egress keys routing *and* the supervise queue/safelist from a single round-trip. Fail-closed (403 -> (None,None)). - egress_addon_core: add `resolve_client_context` (+ `ContextResolverLike`) returning `(Config, bottle_id)`, sharing the fail-closed parse with `resolve_client_config` via `_config_from_policy`. - egress_addon: `_active_config` -> `_resolve_flow` returns `(Config, slug)`; `safe_tokens` set -> per-bottle `_safe_tokens_for(slug)`; the token-allow write/await/archive + the approved-token add all use the resolved slug. Single-tenant (no resolver) unchanged — slug = the env SUPERVISE_BOTTLE_SLUG. New tests cover the resolver, the fail-closed context matrix, and the cross-tenant isolation (an approval lands only in the calling bottle's safelist; the proposal is keyed by the source-IP-attributed bottle; unattributed IPs can't supervise). Out of scope (noted): the git-gate gitleaks-allow hook + supervise_server agent-proposal paths, and websocket DLP (still self.config-only, inert in consolidated mode) — follow-up slices. pyright 0 errors; pylint 9.83/10; unit suite green (1700 tests; the 13 test_sidecar_init /bin/sleep errors are pre-existing NixOS-local noise).
