From f59d974a952e6b88053dc4186346a358c027084e Mon Sep 17 00:00:00 2001 From: Don Garrett Date: Tue, 13 Oct 2026 22:34:02 +0000 Subject: [PATCH] M7.3: nisse-review's first slice A new package over nisse-core: it reviews every ready PR in the repositories its account can read, and posts one COMMENT review. - scheduler: each round, open PRs per readable repository (or the configured repositories); an item per PR, ready unless draft or WIP; closed with the PR. One review at a time, oldest first. - reader: the repository at head and base from Gitea archives, unpacked and read in Python (read_file, list_files, search_code), and its issues; bound to the item's repository; no git, no shell. - review: starts from the PR, commits, diff, comments, closed issues, CI; comment drafts a point on any existing line; post_review posts one COMMENT review at the head, inline where Gitea takes it, else as links in the summary. ask_expert; vault and memory (memory/nisse-review). - L8: posting is an intent; recovery asks Gitea for the marked review and never posts twice; with Gitea down, the item waits. - Failures retried, then said on the PR until the next push. - Startup refuses an account that can push to or administer any repo. - nisse-core gitea: readable_repositories, open_pull_requests, diff, commits, archive, issue, search_issues, reviews, post_review; PR fields. - Bring-up: scripts/review-bringup.sh; nisse-review.example.yaml. - Tests: unit over a fake Gitea and scripted model; a live test (NISSE_REVIEW_GITEA_TOKEN) reviews a PR in a fresh test repository. - Docs: Development Plan M7.3, Tuning Guide (tuning.review.*).
