range-reads.md opens with a table of milestones M0-M5 and the PRs that merged them (#17-#21), replacing a header left garbled by earlier merges, and each milestone's status names its PR. swmr.md says the reader is merged (PR #19) and the writer does not exist. openclaw.md links the Node package's known-issues entry.
