A GPU inference service with no auth of its own must not listen publicly, so reachability comes from this door, which carries the public name, TLS, the per-IP limit and the access log. An ALLOWLIST of upstream paths, never a pass-through: `at` (camera presence, and counts on POST), `city` (area aggregate with its coverage denominator), `postcard` (a place painted from its own retained clip), `generate` (video predicted forward from an observed frame, model_output and unsigned), `gonogo` (proceed-or-wait for something that has to move), `history` and `trend` (how a place changed, paired rather than raw), `health`, `cards`, plus the `cards/`, `clips/`, `verify/` and `v1/` trees. The upstream extends faster than this list, so EMEM_PERCEPTION_EXTRA_PATHS adds single segments at runtime; the compiled set is the floor and nothing can subtract from it. Provenance headers from the upstream are forwarded verbatim, including the warning that every frame after the first of a generated video was never seen. Caller identity (X-Agent-Id, X-Emem-Agent, X-Caller, X-Attester-Pubkey) is passed through as a bucketing key so one noisy agent cannot starve a shared quota; it is a claim, not a verified identity.' operationId: emem_perception_proxy parameters: - description: The upstream path to front.
