Render CodeRabbit's Pause Setting and Follow .editorconfig for New Files - #3903
Fixes two gaps in the agent policy renderer that step 4 of the review cutover (#3877) found before any fleet repository received its rendered files.
Why
CodeRabbit's pause. A repository's .coderabbit.yaml replaces CodeRabbit's central and UI settings unless it sets inheritance: true. The rendered file set only auto_review.enabled and base_branches, so each repository that received one fell back to CodeRabbit's default pause after five reviewed commits. That conflicts with the policy's per-push rounds, and is why the hub's own file sets the pause to 0. The renderer now sets and checks reviews.auto_review.auto_pause_after_reviewed_commits: 0.
Line endings of a new file. A new file was always written LF. Two fleet repositories ask for CRLF in .editorconfig and run editorconfig-checker in CI, so their rendered files would have failed it. A new file now takes the end_of_line its .editorconfig files set, through the EditorConfig core library. An existing file keeps its own endings, as before.
Typed comparison. A strict review round found that YAML false compared equal to a pause of 0, 1 to enabled: true, and TOML 0 to disable_auto_feedback = false. So check passed, or write never repaired, a value the bot reads differently. All of these keys now compare by value and type through one helper.
Changes
scripts/agent_policy.py: the pause key in facts, plan_yaml and judge_yaml; wants_crlf and keep_endings for new-file endings; exactly for the typed comparisons in both planners and both judges. editorconfig joins the inline dependencies, imported only on the write path.
tests/test_agent_policy.py: cases for the pause, the editorconfig endings, the typed comparisons, and the standard-library guard. Each test checkout declares root = true so a parent .editorconfig cannot leak in.
tests/requirements.txt and the mypy override gain editorconfig.
scripts/README.md, repo-config/README.md and docs/pr-reviewer-reference.md state the new behavior.
Verification
The Windows unit job's one failure was a test fixture written in text mode, CRLF on Windows, where the test meant LF. It now writes its bytes exactly.
Full unit suite: 3599 tests OK on the round-one commit. The agent policy consumers' modules (794 tests) pass on the head.
ruff, ruff format, mypy and the prose gate are clean.
agent_policy.py write --dry-run against this repository reports all three files unchanged.
Three local strict review passes are recorded. The first two raised six and two findings, all fixed or disposed of below.
Local Review Findings Not Fixed
introduced, declined under GOVERNANCE.md "Trust Boundaries and Hardening Effort":plan_yaml appends the pause after auto_review's last item. Where an existing .coderabbit.yaml lacks the pause and has a comment between that item and the next key under reviews, ruamel holds the comment on that item, so the new key lands below a comment meant for the next key. The input is a trusted file, and the case needs a hand-written file in that shape: every file this renderer writes carries the key, and the hub's own does. The failure moves a comment and changes no behavior, so it earns no new comment-moving code. Copilot raised it too. A helper that moved the comment was tried and removed, since its review found it crashed write on an emptied list. The maintainer agreed to decline.
pre-existing, recorded: line-ending detection exists three ways: build_dist.py refuses a mixed file, carry.py reads the first terminated line, and this module treats any CRLF as CRLF. This change moved the check rather than writing it.
declined: the try/except around editorconfig.get_properties was raised as over-hardening. It keeps the module's refusal contract, exit 1 with a one-line reason, the same as its YAML and TOML refusals.
A repository's .coderabbit.yaml replaces CodeRabbit's central and UI
settings rather than merging with them. The rendered file set only
auto_review.enabled and base_branches, so every repository that received one
fell back to CodeRabbit's default pause after five reviewed commits. That
conflicts with the per-push rounds the policy asks for, and it is why the
hub's own file sets the pause to 0. The renderer now sets and checks
reviews.auto_review.auto_pause_after_reviewed_commits: 0.
A new file was always written LF, so a repository whose .editorconfig asks
for CRLF failed its editorconfig-checker step on the rendered files. A new
file now takes the end_of_line its checkout's .editorconfig sets, through
the EditorConfig core library. An existing file keeps its own endings, as
before.

YAML's false compared equal to a pause of 0, and 1 to enabled: true, so check passed a value CodeRabbit reads differently and write never repaired it. Both keys now compare by value and type. A repository file replaces CodeRabbit's other settings only while it leaves inheritance unset, which the docs now say.

…ditorconfig
plan_toml compared disable_auto_feedback with a plain equality, so a value of 0 read as false and write never repaired the value check rejects. Both TOML sites now use the same typed comparison as the YAML ones. The EditorConfig lookup reads up the directory tree until a root, so each test checkout now declares one, and the docs say how the lookup reads.

Walkthrough
The agent policy generator now sets and verifies CodeRabbit’s pause setting, compares configured values with type-sensitive equality, and selects line endings for new files from applicable EditorConfig properties. Tests and documentation cover these updates.

Summary
Derived settings and verification scripts/agent_policy.py, tests/test_agent_policy.py, docs/pr-reviewer-reference.md, repo-config/README.md
Generated CodeRabbit settings now include auto_pause_after_reviewed_commits: 0. YAML and TOML planning and verification use type-sensitive comparisons. Tests cover the setting, preservation of existing keys, and rejection of missing or incorrectly typed values. Documentation describes the derived configuration.
Generated file line endings scripts/agent_policy.py, tests/test_agent_policy.py, tests/requirements.txt, pyproject.toml, scripts/README.md
Existing files retain their line-ending style. New files use applicable .editorconfig properties. Tests cover both cases, and the script dependency and import configuration include EditorConfig.
ptr727/ProjectTemplate#3417: That PR updates test jobs to install dependencies from tests/requirements.txt, which this PR updates to include EditorConfig.
Merge Risk: Low · previous review f8a9e
Policy writes may repeat unnecessarily, use the wrong line endings, or leave an invalid pause setting unchanged. Fix these cases before relying on generated-file checks; the remaining merge risk is bounded.

This PR updates the agent-policy renderer to enforce CodeRabbit’s pause setting, honor .editorconfig line endings for new files, and compare structured values by both value and type. One nit remains regarding YAML comment placement when adding the pause key.
Changes:
Adds auto_pause_after_reviewed_commits: 0 to CodeRabbit rendering and validation.
Uses .editorconfig settings for new-file line endings while preserving existing endings.
Adds typed comparisons, tests, dependency metadata, and documentation.

…t Key
ruamel keeps the comments after a mapping's last value on that value, so a key appended to auto_review landed below a comment introducing the next key under reviews. Every appended key, the pause, enabled and base_branches alike, now moves those comments onto itself. The Windows test that set up an LF file wrote it in text mode, which is CRLF there, and now writes its bytes exactly.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Moving ruamel's trailing comments onto an appended key needs one relocation primitive for every site that adds a key, and the first attempt crashed write on an emptied list. The case it served is a hand-written .coderabbit.yaml lacking the pause, where only a comment moves, so the helper is removed and the finding declined.

The renderer writes CRLF for end_of_line = crlf and LF for anything else, cr included, which no fleet repository sets. The README said the file took whatever end_of_line was set.

…or New Files (#3904)
Promotes one change from `develop`:
- #3903 renders CodeRabbit's `auto_pause_after_reviewed_commits: 0` into
each repository's `.coderabbit.yaml` and checks it. A repository's file
replaces CodeRabbit's central and UI settings, so the default pause
after five reviewed commits applied otherwise. A new rendered file takes
CRLF where its `.editorconfig` asks for it, and owned keys compare by
value and type.
The fleet's step 4 of the review cutover (#3877) waits on this release:
each repository's rendered files are re-rendered with it before their
pull requests open.
