## Prompt

Undo the April Tractor rollback and select the reviewed
`wkt/addr_unpacking` branch. Prefer original downstream compatibility
commits to new adaptations, and prepare an offline-verified candidate
while live IB verification is deferred for gateway relocation.

## Generated changes

> `git diff HEAD~1..HEAD -- pyproject.toml uv.lock`

Change Tractor's source from `piker_pin` to `wkt/addr_unpacking` and
lock it at `a966928dead4cbf369ad244834ce9dbe988ac8ca`. Restore application
and test sources byte-for-byte to the committed PR94 tree. Keep the
rejected rollback journal only in ignored local experiment reports.
Preserve Polars 1.36.0 by retaining its exact existing lock blocks;
setproctitle re-resolves from 1.3.7 to 1.3.8. `uv sync --locked` accepts
the resulting graph. Actual imports confirm the reviewed Tractor pin
and Trio 0.32.0, not the hypothesized Trio 0.33.

## Original-history previews

The existing MethodProxy stack is retained. Read-only merge previews
show original `4af885d9` and `b691422b` can be applied without the datad
cutover. Original-source regressions run through temporary in-memory
overlays against the real pinned runtime: seven cases pass and one
cache-hit case fails because `log.at_least_level('info')` looks up INFO
in a custom-level mapping. A separate standard logging correction
produces eight passing cases. Its patch and execution handoff are saved
under ignored `.ai/code-review/reports/pr94_modern_stack/`; no consumer
cherry-picks or source edits are performed by this boundary.

## Verification

- Startup and logging: 13 passed.
- Runtime boot and tagged registrar normalization: 2 passed.
- Locked sync and source whitespace checks pass.
- Original application/test trees are unchanged from PR94 HEAD.
- Consumer overlay with explicit logging correction: 8 passed.
- Correction patch validates against its exact preview tree using a
  private temporary index; the real index is untouched.
- Live IB startup, SIGINT and surviving-pikerd reattachment are pending.
