## Prompt
|
||
|
|
|
||
|
|
Continue Phase 2 of the human-facing E2E plan by implementing a
|
||
|
|
protocol-faithful offline replay provider. Use normal backend discovery,
|
||
|
|
datad, history, quote, search, and typed Tractor control contracts with
|
||
|
|
versioned fixtures, deterministic ordering, no network, no positive
|
||
|
|
sleeps, and no log parsing.
|
||
|
|
|
||
|
|
During review, explain the provider's purpose and placement, evaluate a
|
||
|
|
general package-entry-point backend mechanism, then park replay when the
|
||
|
|
human prioritizes real-backend chart E2E instead.
|
||
|
|
|
||
|
|
## Response summary
|
||
|
|
|
||
|
|
Adds a versioned offline market-data provider implementing normal Piker
|
||
|
|
backend endpoint shapes. Typed control commands advance, pause, resume,
|
||
|
|
snapshot, and inject declared failures while preserving deterministic
|
||
|
|
transcripts. Focused tests validate fixture symbology and finite,
|
||
|
|
repeatable OHLCV history behavior.
|
||
|
|
|
||
|
|
## Files changed
|
||
|
|
|
||
|
|
- `piker/brokers/replay.py` - implement replay scenario, provider, and
|
||
|
|
control protocol machinery.
|
||
|
|
- `tests/_inputs/replay/basic-v1.json` - provide deterministic history
|
||
|
|
and quote input.
|
||
|
|
- `tests/_inputs/replay/failure-v1.json` - provide an acknowledged fault
|
||
|
|
point.
|
||
|
|
- `tests/replay/test_contract.py` - validate scenario and history
|
||
|
|
contracts.
|
||
|
|
|
||
|
|
## Human edits
|
||
|
|
|
||
|
|
The human challenged the original replay-first premise, questioned why
|
||
|
|
test machinery lived beside production backends, proposed dynamic
|
||
|
|
registration, and selected standard package entry points as the future
|
||
|
|
direction for external backend support. The human directly added a
|
||
|
|
source note questioning replay placement, then explicitly placed replay
|
||
|
|
on hold and requested that the completed experiment be committed only
|
||
|
|
as parked work with plugin migration recorded for possible resumption.
