Add AUTHOR_MAP plus a lightweight co-author trailer checker so harvested commits use numeric GitHub noreply identities, reject bot/tool trailers, and require machine-readable credit when a commit says it was harvested from a PR.
Also normalize the local unpushed v0.9 harvest range so existing contributor authors/trailers for HUQIANTAO, Implementist, jrcjrcc, xyuai, cyq1017, idling11, and shenjackyuanjie use GitHub-mappable identities before the branch is published.
Validation: python3 scripts/check-coauthor-trailers.py --author-map .github/AUTHOR_MAP --range origin/main..HEAD --check-authors; python3 -m py_compile scripts/check-coauthor-trailers.py; ruby -e 'require "yaml"; YAML.load_file(".github/workflows/ci.yml")'; git diff --check; negative in-process validation for raw email, missing harvested credit, and bot author cases.
- New github_close_pr tool distinct from github_close_issue; proper PR wording
in tool output, audit records, and gh pr close (not issue close)
- handle_read detects art_/call_/SHA refs and points to retrieve_tool_result
with copy-pasteable hints; error messages show correct tool for each ref type
- Shell delta tool results include the command field so the UI can resolve
task_id-only exec cells when the completion metadata arrives
- Sidebar background shell tasks show the actual command on the primary row
instead of just the task ID; task ID stays available as dim detail
- Tool routing falls back to task_id when exec_shell_wait has no command,
then updates when the completion carries command metadata
- Plan mode prompt explains update_plan as the handoff signal; model waits
for user action instead of continuing to tool around
- Base prompt clarifies handle_read scope (var_handles only) vs
retrieve_tool_result (artifacts/tool-result refs)
- New tests: close_pr_schema, close distinction wording, handle_read artifact
detection, shell_wait task_id fallback, sidebar background task labels
