Why: Background notice runs blocked chat, truncated results, and duplicated deliverable execution.
Evidence: Focused run manager, card, server, recovery and race regressions pass locally; final combination checks are tracked in Dev.
Impact: Persist full results and optional choices, fence dispatch by run identity, retain public child process, and repair legacy projections without a schema change. No paid model trial was run.

Why: Tool calls stayed invisible until execution finished, and turn, tool, timeout, and output caps stopped long tasks early.
Evidence: go test ./internal/runtime/ ./internal/tools/ ./internal/prompts/ ./internal/squadadapter/ ./internal/runmgr/ ./internal/app/ ./internal/settings/
Impact: tool.call.delta and tool.output reach the client; default profile, subagents, and squad no longer cap turns or tool calls; exec timeout defaults to 600s with no hard ceiling. A profile or subagent maxTurns above 0 still applies.

Why: Subagents were a single lightweight call that dropped the hint and wrote their messages into the parent history. Profiles now decide tools, model, and turn cap, and the parent only keeps the summary plus confirmed artifacts.
Evidence: go test ./... passed. New tests cover the six builtin specs, tool execution and whitelist, explore versus writer models, maxTurns, artifact parts, hint text, SpawnAgent pinning, depth-1 refusal, summary artifact lines, and history isolation.
Impact: Squad steps share the general profile (up to 12 lightweight turns, no exec tools). Child runs do not attach the final-turn verifier. Profile fields stay in builtin files, so core.PromptModule is unchanged. The agent-native pin stays a34689c.
