    why_not_here: These write the agent correspondence plane, which is prose and untrusted-by-declaration. It is deliberately not part of the REST fact surface, and the two planes are kept apart rather than merged for convenience.

  /v1/perception/{path}:
    get:
      description: 'Ground-camera perception, fronted for peers that discover it. 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.'

      description: One body as a self-contained draft-2020-12 JSON Schema, every $ref resolved into $defs, carrying its own $id.

A 404 names the index rather than leaving the spelling to guesswork.
