-## Prompt
-
-The human asked for a main-first patch using an off-the-shelf pytest
-plugin to cope with tractor's changing macOS CI flakes without mixing
-that mitigation into PR #505.
-
-## Response summary
-
-Added `pytest-rerunfailures` to tractor's testing dependencies and
-configured the GitHub Actions matrix to retry failures only on macOS.
-Linux and Windows remain strict first-attempt runs, while persistent
-macOS failures still fail after two visible reruns.
-
-## Files changed
-
-- `.github/workflows/ci.yml` - macOS-only pytest rerun budget.
-- `pyproject.toml` - testing plugin dependency and rationale.
-- `uv.lock` - resolved `pytest-rerunfailures` package metadata.
-
-## Human edits
-
-The human selected a main-first mitigation after PR #505 failed two
-different macOS tests on consecutive runs and required the change to
-remain an incremental patch with its own commit plan. The agent
-implemented and verified that direction; no direct manual source
-edits were observed.

-# Raw output - retry flaky macOS CI tests

-failed two different timing-sensitive tests on consecutive runs.
-

-Added the pytest-dev-maintained `pytest-rerunfailures` plugin and

-Linux and Windows receive a zero retry budget; deterministic macOS
-failures still fail after the final attempt and reruns remain visible
-in pytest output.
-
-The lockfile is current, actionlint passed, all 471 tests collected,
-and the four tests covering both observed PR #505 failure areas
-passed with the rerun plugin enabled.

-# Incremental Python Style Enforcement
-
-## Objective
-
-Enforce the mechanically checkable parts of `/py-codestyle` on new and
-changed Python lines without requiring an immediate repository-wide
-cleanup. Keep subjective prose guidance in review policy and expose
-legacy debt separately from blocking CI.
-
-## Current State
-
-- `ruff.toml` sets the intended 69-column limit and enables `E501`.
-- A package-and-test scan reports 1,548 existing violations.
-- Ruff can enforce line length, ordinary syntax rules, unused f-string
-  prefixes, and configured quote style.
-- Ruff cannot directly encode several project-specific layout,
-  docstring, annotation, and technical-prose policies.
-
-The initial configuration is branch scaffolding, not a landable final
-state. The implementation must make changed-code enforcement usable
-before this branch targets `main`.
-
-## Policy Matrix
-
-Document each `/py-codestyle` rule under one enforcement class:
-
-1. Ruff lint rule, enabled directly when the repository is clean.
-2. Ruff formatter setting, used for intentionally formatted files.
-3. Deterministic token or AST check, enforced on changed lines.
-4. Review-only guidance where automation would produce false positives.
-
-Start with native checks for `E501`, `F541`, quote style, import and
-syntax errors. Use custom checks for exact docstring delimiters and
-shape, multiline string construction, double-newline source layout,
-f-string continuation consistency, local annotation placement, and
-boolean-expression layout. Keep symbol-qualified technical prose and
-regression-test rationale as review guidance unless a low-noise warning
-can be demonstrated.
-
-## Changed-Line Harness
-
-Add `scripts/check_py_codestyle.py` with these responsibilities:
-
-- Read a base revision and collect added line ranges from `git diff
-  --unified=0`.
-- Treat every line in an added Python file as changed.
-- Run Ruff with JSON output and the incremental native-rule set.
-- Report only diagnostics intersecting added line ranges.
-- Run token/AST checks and apply the same changed-line filter.
-- Return a nonzero status only for changed-code violations.
-- Offer a separate nonblocking full-tree debt-report mode.
-
-Keep `E501` out of the default global Ruff selection until the legacy
-count reaches zero. The harness should request it explicitly so normal
-repository lint remains useful during migration.
-
-## Verification
-
-Add focused checker tests covering:
-
-- diff range parsing, deleted lines, renames, and new files;
-- 69-column boundaries with indentation and string syntax;
-- compliant and noncompliant docstring delimiters and closing shape;
-- f-string continuation and double-newline source layout;
-- boolean layout and local annotation placement;
-- diagnostics on untouched legacy lines being ignored;
-- diagnostics on newly touched legacy lines becoming blocking.
-
-Run the checker against a fixture base and against the branch diff. Run
-the existing Ruff checks without incremental rules to prove the normal
-lint path remains usable.
-
-## CI Integration
-
-Add a dedicated CI step that derives the pull-request base commit from
-the event payload and invokes the changed-line harness. Preserve a local
-`--base main` mode for developers. Emit normal file, line, column, and
-rule identifiers so forge annotations remain navigable.
-
-Publish the full-tree debt count as nonblocking output. Do not hide or
-silently rewrite existing source violations.
-
-## Commit Boundaries
-
-1. Record the 69-column policy scaffold and provenance.
-2. Add the changed-line Ruff harness and its tests.
-3. Add deterministic token/AST policy checks and fixtures.
-4. Wire the harness into CI and document local usage.
-5. Enable native rules globally only after their legacy counts reach
-   zero, using separate cleanup commits where needed.
-
-## Deferred
-
-Type-checking migration belongs in a separate branch. It should use the
-same incremental principle: establish the tool configuration and debt
-inventory, gate new or changed code, publish nonblocking full-tree debt,
-and tighten global enforcement as annotations and defects are repaired.
