## Prompt
|
||
|
|
|
||
|
|
Same session-initiating `brokerd`-split instruction (see
|
||
|
|
`20260610T170859Z_75cefe10_prompt_io.md`); this is the
|
||
|
|
approved plan's "stage 1": introduce the `datad` daemon
|
||
|
|
machinery additively (nothing routes through it yet).
|
||
|
|
User-decided constraint applied: `datad.<broker>` is a
|
||
|
|
SIBLING of `brokerd.<broker>` under `pikerd`, spawned
|
||
|
|
via the existing `Services` + `maybe_spawn_daemon()`
|
||
|
|
machinery.
|
||
|
|
|
||
|
|
## Response summary
|
||
|
|
|
||
|
|
New `piker/data/_daemon.py` hosting the
|
||
|
|
`datad.<broker>` feed-only daemon-actor: lifetime
|
||
|
|
fixture owning the actor-global `_FeedsBus`, init/spawn
|
||
|
|
fns mirroring `.brokers._daemon` conventions and the
|
||
|
|
`samplerd` sub-daemon precedent, plus root-mod
|
||
|
|
registration, `piker.service` re-exports and a spawn
|
||
|
|
test.
