- `view=raw` — audit/debug path that preserves every stored print.
- The default Tape page options/packets posture is now stock-only, hides `B` / `BB`, keeps calls and puts visible, and applies in-memory min-notional controls immediately.
- Live retention uses a two-tier model:
- API/Redis maintain a bounded hot cache per live generic channel.
- ClickHouse is durable server history; Redis is a bounded hot cache per live generic channel.
- `LIVE_LIMIT_*` controls initial snapshot/hot-cache depth, not total persisted history.
- Browser state is only a rendering window and UI preferences, not a market-data database.
- Devices connected to the same API hydrate from the same server-seen history.
- UI keeps a bounded hot window for rendering performance around the signal view rather than raw noise.
- Options prints can use a deeper dedicated cap via `NEXT_PUBLIC_LIVE_HOT_WINDOW_OPTIONS` without raising every other feed.
- Alert/drawer evidence is pinned and hydrated by id/trace so details remain inspectable after hot-window eviction.
