Generation notes (non-code, verbatim)

Pure docstring-content edits; no signatures, logic, or non-docstring lines touched (confirmed via git diff review).
reST fix patterns applied: blank-line + base-column indent for bullet lists (“Unexpected indentation” / “Definition list …” / “Block quote …”); **bold** in place of an under-length section underline (“Title underline too short”); closing/escaping backticks (“Inline interpreted text … without end-string”); literal-block for an ASCII tree whose | chars tripped “Inline substitution_reference …”.
The pluralized-role idiom is written \\ s in the Python source (so the runtime docstring holds `role`\ s); a bare \ would raise a 3.13 invalid-escape SyntaxWarning. Verified clean via python -W error::SyntaxWarning -c "import tractor".
Verification gate: sphinx-build warning count 24 -> 2 (subagent, docstrings only) -> 0 after the orchestrator added the NEWS.rst blank-line fix; rendered-HTML spot-check confirmed no literal \ s leak; ruff check clean.
