Generated: `get_eps(mod, kind) -> dict[str, Callable]`

|
returning the daemon-kind's ep funcs defined by a
|
||
|
|
backend mod, keyed by ep name, missing eps excluded;
|
||
|
|
sourced from the existing `_eps` grouping table
|
||
|
|
(`'middleware' | 'datad' | 'brokerd'`).

Key exploration findings driving the design (from the
|
||
|
|
planning phase, 3 parallel explore agents + 1 architect
|
||
|
|
agent):
|
||
|
|
|
||
|
|
- the codebase already anticipated this split:
|
||
|
|
`validate._eps` groups eps into 'datad' vs 'brokerd'
|
||
|
|
kinds and `ib/__init__.py` already declared
|
||
|
|
`_brokerd_mods`/`_datad_mods`; `brokers/_daemon.py`
|
||
|
|
carried the literal TODO "rename the daemon to datad
|
||
|
|
prolly once we split up broker vs. data tasks into
|
||
|
|
separate actors?".
|
||
|
|
- the feared kraken feed<->broker "shared ws state"
|
||
|
|
hazard is mild: `NoBsWs`/`open_autorecon_ws`
|
||
|
|
originate in `piker.data._web_bs` (re-exported via
|
||
|
|
`.kraken.feed`); only `stream_messages` is feed-local
|
||
|
|
and it's a pure parser — in-process imports only,
|
||
|
|
each actor opens its own ws conn.
|
||
|
|
- `enable_modules` gates RPC entry, NOT python imports,
|
||
|
|
so backend trading mods may keep importing feed-side
|
||
|
|
helpers in-process post-split.
