Docs: README/websockets.md disagree on WS channel count + README method names are wrong

[TexasCoding]

Summary

README and docs disagree on the WebSocket channel count, AND the README lists wire-channel names where it claims to list SDK method suffixes — autocompleting from the README produces method names that don't exist.

(1) Count mismatch: 13 (README) vs 11 (docs)

README.md:14 says "WebSocket API (13 channels)" and L194 says:

Available channels (13): 11 have dedicated subscribe_* methods … The remaining two (control_frames, root) are reachable through the generic subscribe(channel, ...) escape hatch.

docs/websockets.md:3-4:

KalshiWebSocket, that covers all 11 Kalshi channels

docs/websockets.md:32 ## The 11 channels table enumerates exactly 11 rows. kalshi/ws/client.py exposes exactly 11 subscribe_* methods.

(2) README WS list uses wire-channel names, not SDK methods

L194-199:

dedicated subscribe_* methods — ticker, trade, orderbook_delta, fill, market_positions, user_orders, order_group_updates, market_lifecycle_v2, multivariate, multivariate_market_lifecycle, communications

Actual SDK methods (verified in kalshi/ws/client.py):

README claim	Actual method
order_group_updates	subscribe_order_group
market_lifecycle_v2	subscribe_market_lifecycle
multivariate_market_lifecycle	subscribe_multivariate_lifecycle

A reader autocompleting from this README list types methods that don't exist.

Location

• README.md:14, 194-199
• docs/websockets.md:3-4, 32-46
• kalshi/ws/client.py:436, 447, 458, 469, 476, 484, 492, 500, 511, 519, 527 (the 11 subscribe_* defs)

Recommended fix

1. Pick one channel count and align both docs. If control_frames / root are real AsyncAPI channels, document them once with their actual names and example payloads, then keep the 13 framing. Otherwise drop the 13 and use 11 everywhere.

2. Restate the README list using SDK method suffixes:

ticker, trade, orderbook_delta, fill, market_positions, user_orders, order_group, market_lifecycle, multivariate, multivariate_lifecycle, communications

Or link directly to the docs/websockets.md channel table.
