Introduce frozen, tagged `msgspec.Struct` payloads alongside the
legacy clearing protocol. Separate startup, request, event and
final result phases, with strict directional Tractor receive sets
and local validation before typed objects enter state or transport.
The pure reducer preserves cancel-before-ack intent, correlates
account/request IDs across edits, deduplicates identified fills and
retains bounded terminal dialogs for late events. Snapshot copies
cannot mutate previously published requests or statuses.
Also,
- require owned accounts, positions and an open-order completion
barrier before a backend session accepts requests;
- refresh the migration plan against current Piker and Tractor
branches, preserving the installed dependency pin;
- add 65 offline schema/state/phase tests and eight real actor
tests for typed traffic, rejection, race handling and bounded
teardown.
- include AGPL headers and apply the Python style guide across
protocol code and qualification fixtures.
Ruff and all 73 targeted tests pass on installed Tractor
`5c98ab1f`. Eight IPC tests also pass against local main `5cb600a8`
with its pytest plugin isolated from Piker's duplicate `--ll`
option. Production paper/live adapters and EMS/UI consumers migrate
in subsequent paired changes; no existing endpoint switches here.
