📝 Walkthrough

Walkthrough

The WIP limit no longer treats bot authorship alone as evidence that a pull request is generated. It now requires configured Kaizen branch or title prefixes. Tests cover unmarked and explicitly marked bot-authored pull requests, and documentation reflects the rule.

Changes

Generated pull request WIP classification

Layer / File(s)	Summary
Explicit marker classification and validation src/orchestrator/wipLimit.ts, test/wipLimit.test.ts, docs/03-config-spec.md, docs/04-nightly-pipeline.md	isGeneratedPullRequest no longer uses bot author metadata as a fallback. Tests verify that unmarked Renovate, Dependabot, and GitHub Actions pull requests are excluded, while explicitly marked pull requests remain included. Documentation lists the supported branch and title prefixes.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 4f1d4

The change correctly excludes unmarked bot pull requests while preserving the sync-PR exception, but the configuration and pipeline documentation should describe that exception consistently to avoid limited operator confusion. No actionable merge-blocking risk remains.
