NOTE: diff-ref mode entry (code committed in the same

commit as this log); backfilled from the live dev
|

session transcript per the `/prompt-io` skill rules.

> `git log -1 -p --follow -- piker/data/feed.py`
|
|
|
|
Generated: `open_feed()` spawn cutover with the
|
|
`maybe_spawn_datad` import done "relative-direct" from
|
|
`._daemon` — NOT via `piker.service` — to dodge a
|
|
partial-init cycle: when `piker.data.feed` loads as
|
|
part of `piker.service.__init__` executing its own
|
|
`piker.data._daemon` import, the service pkg is
|
|
mid-init and its `maybe_spawn_datad` binding does not
|
|
exist yet. The `open_feed_bus()` local-state sanity
|
|
assert flips `'brokerd' in servicename` ->
|
|
`'datad' in servicename` (the only actor-name assert
|
|
in the tree, verified by grep).
|
|
|
|
> `git log -1 -p --follow -- piker/brokers/_daemon.py`
|
|
|
|
Generated: `_setup_persistent_brokerd()` slimmed to
|
|
console-log setup + pinned-open ctx; drops the bus
|
|
alloc, the `assert not feed._bus`, the service nursery
|
|
(backend `open_trade_dialog()` ctxs own their task
|
|
trees) and the `eg.ExceptionGroup` handler. The
|
|
`piker ledger` ad-hoc actor enters this same slimmed
|
|
fixture — exactly what it needs.

Verification (from session): per-suite gates green at
|
|
this commit (services 5-passed incl. the new negative
|
|
assert, feeds 3-passed); a headless live smoke
|
|
(`maybe_open_pikerd` + `open_feed(['xbtusdt.kraken'])`
|
|
on an alt registry port) confirmed quotes flowing via
|
|
`datad.kraken` + `samplerd` with `check_for_service(
|
|
'brokerd.kraken') is None`. Known pre-existing flake
|
|
documented: `test_multi_fill_positions`' second
|
|
in-proc runtime boot wedges ~50% (zombie subactor w/
|
|
unread parent-IPC bytes); reproduced with the split
|
|
fully reverted so NOT a regression of this work.
