## Prompt

The human approved refining Piker's logger-name handling after the
wider service test exposed a stale parent-logger assertion during the
tractor tagged-address compatibility work.

## Response summary

Changed Piker's logger helpers to remove only an exact `piker.` prefix,
preserving complete requested submodule names. Removed daemon startup
assertions that incorrectly required parent logger names and added a
regression covering both logger factories and names that the old
character-set stripping silently corrupted.

## Files changed

- `piker/log.py` - exact relative logger-name derivation.
- `piker/service/_daemon.py` - remove stale parent-name assertion.
- `piker/data/_daemon.py` - remove stale parent-name assertion.
- `piker/brokers/_daemon.py` - remove stale parent-name assertion.
- `piker/clearing/_ems.py` - remove redundant logger assertion.
- `tests/test_logging.py` - package logger namespace regressions.

## Human edits

The human explicitly approved this follow-up after reviewing the
residual Piker service-suite gap. The agent implemented and verified
the refinement; no direct manual source edits were observed.
