 | AD-002 | **Concurrency is bounded per LLM backend, not per project.** One concurrent Claude session per OAuth credential pool; one concurrent session per llama-server instance. Containers with disjoint backends may run in parallel. | The single-thread invariant is about *backends*, not pipelines. **(a) Anthropic OAuth credentials race on token refresh** — each container uses a per-session `CLAUDE_CONFIG_DIR`, so Claude Code's native lockfile-based OAuth refresh handles contention automatically without external serialization. (Legacy: set `CLAUDE_EXTERNAL_LOCK=1` to re-enable the old `flock session.lock` wrapper for rollback.) **(b) llama-server has finite VRAM and one KV cache** — parallel inference thrashes the cache and risks OOM. All llama-backed agents serialize on the same lock. **(c) Disjoint backends are free to parallelize.** Today `disinto-agents` (Anthropic OAuth, runs `review,gardener`) runs concurrently with `disinto-agents-llama` (llama, runs `dev`) on the same project — they share neither OAuth state nor llama VRAM. **(d) Per-project work-conflict safety** (no duplicate dev work, no merge conflicts on the same branch) is enforced by `issue_claim` (assignee + `in-progress` label) and per-issue worktrees — that's a separate guard that does NOT depend on this AD. |
