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.

Generated: the fail-fast originally landed in
|
||
|
|
`broker_init()` but was relocated to `spawn_brokerd()`
|
||
|
|
mid-implementation after realizing `piker ledger`
|
||
|
|
calls `broker_init()` directly even for paper accounts
|
||
|
|
on datad-only backends (would have crashed the cli);
|
||
|
|
the service-spawn path is the correct enforcement
|
||
|
|
seam. Error text:
|
||
|
|
|
||
|
|
Backend 'kucoin' offers NO `brokerd` (live
|
||
|
|
order-control) eps!? It is likely a datad-only
|
||
|
|
provider, use paper-mode for clearing instead.
|
||
|
|
|
||
|
|
(verified live via a `trio.run()` unit check.)

Generated: in `load_aio_clients()`, when `client_id`
|
||
|
|
is the 6116 default: `datad`-named actors offset +16
|
||
|
|
(disjoint from `brokerd`'s linear `client_id + i`
|
||
|
|
retry range), other non-`brokerd` (ad-hoc test/cli)
|
||
|
|
actors +32. Rationale from the plan's risk register:
|
||
|
|
post-split BOTH per-broker daemons connect to the same
|
||
|
|
TWS/gw endpoint; a shared default id collides and
|
||
|
|
burns up to `connect_timeout * retries` (90s) in
|
||
|
|
retry cycles.
