## Prompt

Prime PR #512 for landing by applying the repository Python style and
typing policy across changed examples, reviewing and correcting the
result with delegated agents, validating it, and auditing documentation
changes since PR #460 for broader follow-up work.

## Response summary

Completed a branch-wide style, typing, and docstring pass over the
changed examples. Reworked the dedicated registrar example so it proves
external discovery, handles bind collisions, publishes readiness
atomically, and shuts down cleanly across platforms. Staged review moved
it under the discovery examples, introduced an async lifecycle manager,
and captured public-subsystem, Piker, and pytest follow-ups. Corrected
discovery and typed-messaging documentation after cross-checking runtime
behavior.
Created issue #514 for typed `Start` contracts and linked its planned
sender-side argument validation from the messaging guide.
Independent review passes were repeated until no actionable findings
remained. Static checks, Sphinx, runnable examples, Trio coverage, and
focused registrar checks passed; Ctrl-C debugger failures remain
unclassified after one case reproduced on untouched `main`.

## Files changed

- `examples/discovery/dedicated_registrar.py` - implement robust
  standalone registrar discovery and teardown.
- `examples/**/*.py` - apply style, typing, docstring, and terminology
  corrections to the 38 changed example modules.
- `docs/guide/discovery.rst` - document actual registrar and
  multi-registrar behavior.
- `docs/guide/msging.rst` - document actual validation and codec-hook
  boundaries.

## Human edits

The human selected PR #512, required the `/py-codestyle` policy and
typing improvements throughout the examples, required delegated review
agents to find additional fixes, authorized agents to own and push their
code through the proper review process, and requested a broad audit of
documentation changes since PR #460 rendered as an evolving Taken WIP.
The human then required the earlier `ParamSpec` proposal to be captured
as a dedicated GitHub issue and linked from the current docs patch.
The human also required the registrar demo to move under discovery, use
structural matching and an async context manager, explain socket ownership,
and preserve public API, Piker, and pytest-harness follow-ups.
The human also explicitly retracted messages intended for another
session; those messages did not direct the result. No direct manual
source edits were identified; the agent applied the human-directed
changes.
