Added

• Add a durable per-run child fan-out budget with a default cap of 64 across static, dynamic, workflow, and nested child admissions. Thanks to @asjer for #1031.
• Add an opt-in per-session cap for concurrently active top-level async runs, with atomic admission, resume transfer, status/Fleet/RPC/doctor visibility, and release gated by the verified process-terminal behavior from #1030. Thanks to @asjer for #1029.
• Add a live Prompt Audit drawer to Fleet for current-session foreground children. Prompt text is visible in the drawer, kept outside serializable Fleet state, and redacted from foreground input, transcript, metadata, result, progress, and run-history artifacts (#1021).
• Add a global timeoutMs config option that sets the default run deadline for single, parallel, and chain launches (foreground, plus plain single-agent async) when neither the call nor the selected agent provides a timeout. It reaches parallel (tasks: [...]) and chain launches, which never adopt an agent's frontmatter timeoutMs (that default applies to single-agent launches only), so a long fan-out no longer falls back to the built-in 30-minute default and gets killed mid-run. Explicit call timeoutMs/maxRuntimeMs and agent frontmatter defaults still win; composite async runs stay unbounded at the top level by design. Thanks to @shaharmor for #1018.
• Add a PI_SUBAGENT_TASK_DELIVERY environment setting (auto | file, default auto) controlling how the task text reaches child Pi processes. file writes the task to a temp task.md referenced as @<path> instead of embedding it in argv, for hosts where endpoint protection (EDR) pre-execution command-line scanning denies children whose argv embeds a long natural-language task. Thanks to @yanqianglu for #1028.
• Escalate startup retries to file task delivery after an unexplained zero-activity SIGKILL child exit, so EDR-denied launches self-heal on retry in both foreground and background runs. Thanks to @yanqianglu for #1028.

Fixed

• Open Fleet Prompt Audit with the authored task visible by default and show a short live task summary in the normal Fleet detail pane (#1021).
• Use full task-text hashes for LLM intent arbiter memoization so same-prefix review and implementation tasks cannot share a cached verdict.
• Terminate async Pi writers as owned POSIX process groups on stop and timeout, and keep terminal process proof unknown until process-tree exit is verified. Thanks to @asjer for #1030.
• Explain when a requested mission is scoped to another worktree by naming the current project root and mission directory (#1024).
• Preserve the configured output reference when explicit acceptance rejects an otherwise completed foreground child, so useful reports remain available (#1023).
• Reject configured worktree base directories inside the agent extensions directory, including symlink aliases (#1014).
• Align unnamed intercom fallback orchestrator targets with pi-intercom's 18-character registered presence names so subagents without an explicit session name can reach their orchestrator. Thanks to @mystery4f for #1017.
• Stop reading hyphenated adjectives like "must-fix items" or "should-fix tests" as implementation intent, which made the completion mutation guard hard-fail read-only review runs with a false "completed without making edits" error. Severity compounds (must|should|needs + dash + verb) are stripped before verb matching across every mutation pattern (incl. update/add/apply/make/do siblings), the acceptance-level write-capability check, and the patch-scope pattern, while CLI flags ("eslint --fix", "prettier --write") and clause-level dashes ("branch—fix it") keep their write intent. Thanks to @MarcusNeufeldt for #1020.
• Add an optional LLM intent arbiter: when the completion guard is about to hard-fail a run that made no edits, a model decides — from the task text alone, never the child's own report — whether the task actually instructed file changes; only a confident read-only verdict rescues the run, before any failure state is published. Covers single, parallel, and chain foreground runs; enabled by default; set PI_SUBAGENTS_LLM_INTENT_ARBITER=0 to disable. Thanks to @MarcusNeufeldt for #1020.
• Tolerate empty-string entries in acceptance-report string-array fields instead of rejecting the whole report. Thanks to @hjiang for #1015.
• Let single external-cli workflow children ignore inherited Pi models so model-less external runners start instead of failing preflight. Thanks to @twosunnus for #1016.
