Prevent idle event waits from stalling user follow-ups

Load zshrc and evaluate the submitted command in the same noninteractive worker so functions, aliases and unexported shell state survive. Preserve private overrides, working directory, stdin restrictions and command exit status.

@@ -223,14 +236,16 @@ Key invariants:
 - `recall_tool_history` excludes earlier calls to itself; archived tool results remain searchable by query or exact `tool_use_id`
 - Before progressive summarization drains messages, `ConversationMessage::archive_tool_results()` moves tool-use/result pairs into `tool_result_archive`
 - Bedrock prompt caching uses three cache points: system prompt, second-to-last history message, and tool configuration
+- Bedrock requests project reasoning history for the selected foundation model: omit unsigned response-only reasoning and signed blocks from incompatible models while preserving Claude's complete signed blocks for tool continuations. Keep durable/UI history intact, remove messages emptied by projection, and use the discovered foundation model when invocation targets an opaque inference-profile ARN.
 - `ensure_tool_results_paired()` enforces Bedrock's invariant that every `tool_use` has a matching `tool_result`
 - Progressive summaries are prepended to provider requests as a user/assistant pair; direct-provider runs compact their live transcript at a checkpointed `ReadyToCallModel` boundary before another model call, while background summarization remains independent for session-owned runtimes
 - Direct-provider progressive compaction runs in a separate request alongside foreground work. Start early against the smaller usable history budget of the current and terminal-use profiles, including each profile's prompt/tools/output reservation. Apply a result only at a safe model boundary after validating its exact snapshotted prefix, preserving all newer history and recomputing live context accounting. Wait for pending compaction only after context exhaustion; cancellation and terminal cleanup must remain immediate. Cleanly completed conversations may accept a late summary while idle; stale, cancelled, or superseded generations must never replace a newer run's history.
 - Loop prevention in `controller.rs` detects repeated tool failures (3+ identical) and injects a corrective instruction
-- Direct-provider long-running shell follow-ups retain CLI tasks as UI projections while command monitoring and completion stay owned by the same provider run
-- A direct-provider command completion is only queued when the terminal reports it; the CLI task remains active until the provider run applies that completion at a safe boundary and deactivates it
-- Provider command ownership is resolved from the active slot or its durable snapshot by block/action identity; completion arriving during restore is persisted into that snapshot and must never fall back to the legacy assessment path
-- Direct-provider completed-command assessments are hidden, tool-free root-task turns whose output and hidden input survive CLI-task deactivation and restoration
+- Agent-requested shell commands run as independent, noninteractive background jobs with closed stdin and no PTY. User-typed commands retain the normal terminal execution and rendering path. No model turn may poll commands, write process input, or take over a shell; unavoidable interactive commands are given to the user to run themselves.
+- A successful shell launch returns `BackgroundJobStarted` and yields the provider generation only after every tool result in that batch is committed. The process belongs to `BackgroundJobsModel`, independently of conversation cancellation or subsequent user input. Running or undelivered jobs keep orchestrated children pending rather than reporting premature success.
+- Background completion sends command, bounded logs, and actual exit status as hidden execution evidence to the owning conversation when it is idle. Completion is not a user request or new authorization, must preserve the user's draft and selected conversation, and is acknowledged only after acceptance. Failed, cancelled, and successful jobs all deliver terminal evidence.
+- `/background-jobs` lists persistent history scoped by git project or directory with adjustable filters, logs, and process-tree termination. Inline tool panes show status only: animated running indicator, green success, red failure, gray cancelled square. Full logs live in private temporary files; View logs appears only while a retained log is readable, and truncation in model context is explicit.
+- Restoring history never replays a command or wakes an agent from old completion records. Local interrupted jobs become cancelled; remote running jobs reconcile with their owning daemon before claiming an outcome and remain controllable after reconnect. Process cancellation is scoped to an owned process group/job object, never a reused PID or another conversation's command.
 - ACP remains a separate session-owned runtime; direct-provider cleanup must not move ACP lifecycle into `ProviderRun`
 - Orchestrated child conversations are leaf workers: nested `RunAgents` and legacy `StartAgent` calls are rejected before autonomy or permission bypasses, and child requests do not advertise delegation tools
 - Direct-provider `RunAgents` acknowledges linked local children and yields the parent generation after committing its launch results. Other tools in that launch batch are explicitly not executed. Persistent `LocalAgentGroup` membership survives parent follow-ups; only when every child reaches `Success`, `Error`, or `Cancelled` (with provider cleanup complete), or is removed/deleted, does one combined completion message wake the parent. `Blocked`, `TransientError`, and `WaitingForEvents` children remain pending. Restarts invalidate undelivered group results, and group delivery is confirmed only after the parent input is accepted.
@@ -245,7 +260,7 @@ Key invariants:
 - `app/src/ai/blocklist/action_model/risk_review.rs` assesses Galaxy Decides actions using the terminal-use model in a separate, tool-free request, falling back to the base model when unconfigured. Risk 0–3 runs; risk 4–5 and denylist/protected-path/workspace restrictions deny automatically. Galaxy Decides never requests human permission. Denials return reasons so the agent can revise its scope/justification or choose a safer approach.
 - Risk reviews carry chronological available recorded user requests, including intermediate restrictions; oversized review context denies rather than discarding revocations, separate from agent rationale/delegated scenarios. Worker reviews inherit root-conversation authorization; agent claims never establish permission. Later revocations take precedence. An explicitly requested ordinary non-force push within the stated/established remote and branch may be risk 3; external visibility alone is not risk 4. Force/deletion/out-of-scope pushes, secrets, and production changes remain stricter.
 - Invalid, unavailable, oversized, or timed-out assessments never grant execution. Assessment calls are bounded to 30 seconds. Reviews bind conversation, action contents, execution identity, profile mode and environment. Cancellation, replacement and cleanup invalidate callbacks; stale approval clicks are not authorization.
-- Approval of a running agent command covers subsequent output monitoring and PTY input for that same conversation-owned active block while the agent retains control. Validate block and launch-action identity; never extend PTY writes to a finished command, another conversation, or a fresh shell prompt. A finished owning block may return its final snapshot without additional permission.
+- Approval of an agent shell command covers launching that exact background job and terminating its owned process tree. It does not grant interactive input or another command. Cancellation must match the job and owning conversation; users can manage jobs directly in `/background-jobs`.
 - Galaxy Decides risk assessment appears only as a transient “Checking permissions…” status above the input, not a per-tool permission pane. Ask First keeps its actionable approval panes. `PermissionReviewChanged` refreshes the owning conversation’s status bar.
 - Safe inspection and output polling do not add risk-review model calls. A narrow shell fast path accepts validated `pwd`, `ls`, Git version, and hardened Git status/diff forms; shell expansion, chaining, redirects, unknown flags and unhardened Git commands still require review. Explicit restrictions are checked before fast approval. Galaxy Decides skips user-question pauses. External ACP/CLI agents retain their own protocol permission flows; unstructured ACP requests must not grant Galaxy terminal mutations.

 pub(crate) const CODING_DELEGATION_GUIDANCE: &str = "## Coding Delegation\nFor coding tasks, actively look for bounded implementation or review work to offload to available subagents early. Prefer delegation for substantial independent changes or a focused review of completed work; give the child the known files, just enough context, an explicit implementation or research role, the expected deliverable, and a validation check. The parent owns integration and reviews the result, returning corrections to the same child when needed. Do not duplicate delegated implementation while it runs. Keep trivial edits and tightly dependent steps local when delegation would add delay. Research and plan-mode assignments remain read-only. Delegate only when delegation tools are advertised; child agents are leaf workers and must not spawn other agents.\n\n## Dueling Models Review\nAfter a substantial coherent set of authorized code changes, the parent must request an independent read-only subagent review before reporting completion. Skip this workflow for trivial edits. Always select an available reviewer model; provider or model diversity is a preference, never a reason to skip review. Prefer a capable reviewer with a different model and a different provider from the implementer, using only the advertised model catalog. If no suitable different-provider option exists, select the next best capable different model; if only one model is available, use a separate reviewer conversation and disclose that limitation. Do not invent model IDs or provider diversity. Give the reviewer the requirements, changed files and diff scope, implementation model ID, completed checks, and known uncertainties. Ask for concrete correctness, regression, security, or missing-validation findings with file references and evidence; distinguish blocking findings from optional suggestions. The reviewer must inspect the current code and return findings or explicit LGTM, never rubber-stamp a summary. The parent evaluates findings, sends actionable corrections to the same implementer, and sends the revised diff and validation evidence back to the same reviewer. Continue repair and re-review until the reviewer returns LGTM for the current changes. Changes after approval need review again. Do not force stylistic churn, hide disagreements, or claim LGTM without an actual reviewer response. If verification is unavailable or a disagreement requires user input, report the concrete blocker and remaining findings honestly. The parent coordinates this loop; leaf implementers report readiness for parent review and never spawn reviewers themselves.\n\n";

This applies equally to the parent and subagents, follow-up instructions, tool results, command polls, and restored or compacted context.

Search until you have just enough context to make the requested change. Read the immediate implementation and a relevant example or test as needed, then make the smallest coherent change. The parent can review and request follow-up changes; do not try to anticipate every possible review concern before editing, and still validate your own work. Validate that slice before expanding the investigation. Do not inventory every related subsystem before editing. Further discovery must resolve a concrete uncertainty that affects the next change. When a local code change is reversible and a focused build or test can settle an uncertainty, make a small, evidence-based attempt and use the result to refine it instead of searching for complete certainty. Do not guess APIs or edit files you have not inspected. Read known files directly and batch independent focused reads; avoid repeating discovery already supplied by the parent. Prefer the nearest relevant check before a full build. Investigate first when a mistake could destroy data, affect production, expose credentials, or create irreversible external effects. For review-only work, inspect the changed code and its immediate dependencies, then report actionable findings; expand the search only to test a specific suspected defect. For delegated implementation work, include known paths and symbols, established findings, changes to preserve, a concrete first change, and its acceptance check; distinguish known facts from unanswered questions.

Keep stdout and stderr live: do not hide them in subprocess capture_output/PIPE, redirect everything to a file, or buffer a whole validation suite and print only its final tail. If a log file is needed, stream through tee while preserving the original command's exit status. Use non-interactive, non-watch modes and disable pagers. Give intentionally quiet commands a descriptive tool title so the user knows what is running; silence alone is not evidence of a hang.

Background jobs continue independently; Galaxy automatically sends the command, logs, and exit status when a job succeeds, fails, or is canceled. Wait for that completion delivery before work that depends on the final outcome; independent work may continue. Do not use wait_for_events for background commands or restart a command merely because it is still running. If the user explicitly asks for current status or a log review, inspect the available evidence and answer now. When read_files is available and permitted, read the retained log path for the requested snapshot; do not defer that inspection until command exit or park the user request in a wait.\nUse noninteractive flags, disable pagers, and keep the job's main process in the foreground: do not append '&', use nohup/disown, or detach child processes. If interaction cannot be avoided, give the exact command to the user to run in their own terminal instead of executing it. Commands typed by users retain their normal interactive terminal behavior. Each job starts in the supplied working directory and inherits the session environment; cd/export changes inside a job do not persist to later jobs. Use explicit paths or a cd within that job when needed. Galaxy stores stdout/stderr in temporary logs; do not hide all output in another file. The user can view retained logs and terminate jobs through /background-jobs.
