## Prompt

The human asked to sanity-check the current PR94 landing state against
the qualified new Tractor pin before deduplicating branch history. After
the initial offline checks passed, the human authorized changing the
selector to piker_pin, resolving the lock, and verifying the installed
dependency without the temporary local-source PYTHONPATH override.
The human explicitly authorized network resolution and a scoped update
of Tractor/runtime dependencies while preserving unrelated packages.

## Response summary

Updated the branch selector and lock to published piker_pin@b64c89f0.
Installed the exact locked Tractor revision, verified its installed
source metadata, and reran 14 offline logger/startup cases without a
local Tractor source override. Preserved the rest of the environment.

## Files changed

- `pyproject.toml`: select piker_pin and bound Polars below 2.0.
- `uv.lock`: lock b64c89f0 and Polars/runtime 1.44.2.
- This provenance pair.

## Verification and limits

14 distinct offline cases passed against the installed Tractor update
with the existing Polars 1.36 installation. The actor.uid deprecation
warning remains. No live provider/order testing occurred.

The initial resolver selected Polars 2.0 and rejected retaining 1.36
for its Windows target. The human then requested the latest pre-2.0
release instead. PyPI metadata identified non-yanked stable 1.44.2;
adding `<2.0.0` to the existing lower bound and relocking succeeded
with both polars and polars-runtime-32 at 1.44.2, without platform edits.
The raw partner retains the original, superseded 2.0 generation history.

The scoped install changed only Tractor. Polars 1.44.2 is locked but
not installed or data-path qualified yet. The human's existing staged
checkpoint is preserved; the pre-2.0 correction is in the worktree.
No history cleanup, staging or commit was performed by this agent.
