+Implemented, reviewed, merged, and validated.
+
+Summary:
+- Updated Orchestrator routing guidance to prefer starting additional independent queued Tickets during explicit queue review/routing when capacity exists and safety checks pass.
+- Preserved the rule that queue notifications are not unattended scheduler triggers.
+- Preserved the durable `queued -> inprogress` acceptance gate before worktree creation, Pod spawn, or implementation side effects.
+- Explicitly forbids starting unqueued Tickets to fill capacity.
+- Added required parallel-start checks for Ticket body/thread/artifacts, Ticket relations, OrchestrationPlan, workspace/worktree dirty state, visible Pods, branches, and conflict/dependency notes.
+- Added bounded idle/defer reasons when capacity appears available but queued work is left waiting.
+- Updated multi-agent workflow guidance for separate worktrees/branches/narrow write scopes and read-only Reviewer default.
+
+Implementation:
+- Coder commit: `492fe06 workflow: prefer parallel queued starts`
+- Reviewer approved with no blocking findings.
+- Merge commit completed after ToolExecutionContext cleanup.
+
+Validation after merge:
+- `git diff --check`
+- `cargo run -q -p yoi -- ticket doctor`
+- `nix build .#yoi`
+
+`cargo check --workspace` was intentionally omitted because the change is workflow-resource text only and Nix build covered packaged resource integrity.

 All passed. Residual note: this is workflow guidance, not runtime scheduler enforcement, which is consistent with the Ticket scope.
