MergeConfigPr approvals had a fully-implemented approve handler
(run_merge_config_pr, ff_push_to_main, mark_pr_merged) and dashboard
display, but no way to submit one. An agent with the `approvals` tool
group calling request_merge_config_pr(agent, pr_number) is the missing
piece.
What this adds:
- RequestMergeConfigPr variant in hive-sh4re AgentRequest + ToolGroup::Approvals
- submit_merge_config_pr: fetches PR head sha (the drift-gate reviewed sha),
queues a MergeConfigPr row, sets fetched_sha, emits approval_added with
pr_number so the dashboard card links to the forge PR
- handle_request_merge_config_pr: topology (require_descendant) +
tool-group (require_group(approvals)) guards before submit
- socket_server/mod.rs: dispatch arm for RequestMergeConfigPr
- hive-ag3nt MCP tool: request_merge_config_pr with full description
- docs/tools/lifecycle.md: documents the new tool + boundary table row
Unlike submit_apply_commit, no flake pre-flight at submission time (eval-
verify happens at approval time inside run_merge_config_pr, same as the
rest of the merge pipeline). Applied repo must already exist (guard added
with a clear error message pointing at request_apply_commit for first-spawn).
reqwest has no UDS transport, so unix: upstreams dial the socket
directly with a raw hyper/1.1 client per request instead. http(s)://
upstreams are unaffected (still go through the existing reqwest path).
Adds hyper (client, http1), hyper-util (tokio IO adapter), and
http-body-util as direct hive-ag3nt dependencies - all three were
already present transitively via reqwest, this just uses them
directly for the new code path.
db::apply_migrations runs ALTER lists and ignores duplicate-column
errors (turn_stats' pattern); approvals, operator_questions, broker
reminders, and scheduled_prompts drop their hand-rolled
pragma_table_info guards. broker's acked_at migration stays bespoke —
its backfill must only run when the column was just created
The test's invalid-values list included "low" which was valid before
this PR but is now a legitimate effort level. Replace with "lowest"
(still invalid) so the test keeps its coverage without false-failing.
claude --effort now accepts low, medium, high, xhigh, max.
Expand EFFORT_LEVELS from 3 to 5, update NixOS enum + description,
and fix the stale doc comment in web_ui.rs.
Closes#2220
