chore(review): reduce repeated CodeRabbit evidence requests

[tt-a1i]

Problem and value

CodeRabbit's evidence summary on #385 still referred to earlier validation revisions after the PR description had been updated. Repeating that summary can prompt contributors to rerun checks they have already supplied. The walkthrough also repeats a file-by-file inventory alongside the high-level summary.

This change asks each evaluation to read the latest description, discussion, and CI; identify the specific changes that invalidate earlier local evidence; and report only remaining gaps with the responsible role. Summaries identify their revision and are limited to 100 words; the changed-files summary is disabled. CONTRIBUTING clarifies how to refresh stale pre-merge results after description or CI updates. Scope: the maintainer requested a small reduction in repeated evidence requests and verbose output.

Stability impact

• Impact class: repository review policy/configuration. Only .coderabbit.yaml and CONTRIBUTING.md change.
• Automatic incremental reviews, the chill profile, both warning-mode checks, disabled request-changes automation, and required final-head CI are preserved. Reused local evidence retains its original revision and needs a reuse rationale; evidence invalidated by new behavior still needs rerunning. An inability to read evidence must be reported as an access limitation.
• This does not add an event trigger or guarantee that editing a PR description reruns checks. The existing @coderabbitai run pre-merge checks command remains the refresh mechanism. No supported independent promotion-footer toggle was found, so none was invented.
• No unrelated changes. Reverting these two files restores the previous review behavior.

Tests run

Base 93ffea4 to candidate 06408b6 (includes main after #385; follow-up clarifies that intervening base or scope changes can require broader review):

• Parsed YAML with Ruby YAML and validated the resulting JSON using Ajv's draft-2020-12 validator against the live official https://coderabbit.ai/integrations/schema.v2.json: passed.
• git diff --check: passed.
• Read-through of revised policy branches (reused from f2787c0; the follow-up adds base/scope invalidation explicitly, with schema and whitespace checks rerun at 06408b6): new behavior requires affected checks; unaffected local evidence retains its revision; pending fork CI belongs to maintainers; unavailable evidence is not described as absent; a description-only update uses the documented refresh command. Existing remote gates remain required.
• Checked documented summary settings and refresh command against https://docs.coderabbit.ai/reference/configuration and https://docs.coderabbit.ai/pr-reviews/pre-merge-checks.
• Renderer/runtime tests omitted: this changes only repository policy and bot presentation, with no runtime, packaged Skill, or shared test infrastructure change. Live CodeRabbit adherence and reduced repetition remain to be observed on subsequent reviews; schema validation does not establish those outcomes.

Visual evidence

Not applicable: no renderer or Viewer output changes. The bot's future comment presentation has not been visually verified.

Generated artifacts

None. Neither changed file is an authoritative input to the shipped ZIP, Gallery, or examples.

📝 Summary

Updates CodeRabbit policy to use current PR context, reuse valid revision-specific evidence, report only remaining gaps, and limit summaries to 100 words. It disables changed-file summaries and documents refresh steps after description or CI changes. Reviewed base: unavailable in the checked repository; reviewed head: 06408b6b36ce0d0d4d61e2eea60d54443a4edc27. Author-reported validation included YAML/schema checks, git diff --check, and policy/documentation review. No reused evidence or observed CI results were provided. Runtime, browser, and perceptual tests were not run.

Walkthrough

The review configuration disables the changed-files summary and defines a 100-word snapshot format with explicit revision and validation details. It requires reviewers to check the latest PR body, CI, and discussion before repeating requests or warnings. New guidance covers invalidated and reusable evidence, access limitations, final-head checks, and consolidated evidence gaps. CONTRIBUTING.md documents the same revision-aware procedures for the automated review pilot.

Full details: Validation Evidence

Explanation

The repository-only policy change has appropriate targeted evidence. The authoritative diff changes only .coderabbit.yaml and CONTRIBUTING.md; no runtime, visual, packaged Skill, or generated-artifact inputs changed. At head 06408b6b36ce0d0d4d61e2eea60d54443a4edc27 with base 93ffea49f032dede095460173ec2cfe13fb7ca31, git diff --check and YAML parsing pass, and the official schema contains reviews.changed_files_summary. The PR body correctly separates author-reported checks and reused evidence. However, final-head CI is not complete: test (18), test (20), test (24), and webm-artifact remain in progress. The current CodeRabbit status is also pending. Pending checks cannot prove the required final-head pass.

Resolution

Maintainer/CI owner: wait for the four pending checks on head 06408b6b36ce0d0d4d61e2eea60d54443a4edc27 and confirm that all required final-head checks succeed. Then refresh the pre-merge assessment with @coderabbitai run pre-merge checks and report the final CI and evidence revisions. Do not rerun unrelated renderer, browser, visual, or artifact checks unless a changed input invalidates them.
