Address review findings without changing behavior elsewhere: - routes/jobs: stop exposing storage_uri; sanitize Content-Disposition filename and add nosniff + attachment for non-raster artifacts; clamp negative caps. - store: keep db_url out of storage_uri and logs. - manager: shlex-quote the scan path; drop placeholder provenance; skip quota and SSE on dedup hits. - base: close the stale session on reset. - capabilities: default supports_artifact_download to False (fail-closed). - config: robust legacy block_network parsing. - openshell: parse AIQ_OPENSHELL_ADAPTER_FILE_TRANSFER as an explicit boolean; map download exit code 3 to is_directory. - citation_verification: preserve a link only when its destination is artifact://. - UI: PDF fetch timeout + Content-Length pre-check, scoped cookie forwarding, gap/MIME-gated image embedding; proxy preserves upstream status. Make the chart and data-table skills provider-neutral (reference the runtime sandbox dir instead of a hardcoded /workspace), plus README/markdownlint cleanups.

Lifecycle (cancellation can preempt a running sandbox): - base: split the single lock into an operation lock (serializes calls/retry, unchanged) and a short state lock guarding the session ref + a terminated flag. close()/terminate() now tear down out-of-band so a cancelled/timed-out job interrupts an in-flight execute instead of waiting for it; a terminated provider refuses further work. Lock order is operation -> state only, so no deadlock. - deepagents_runtime.terminate() + runner: interrupted jobs (cancel/timeout) call terminate(); normal paths still close() gracefully. Visualization honesty (no new loops/cost): chart/data-table skills + orchestrator/ researcher prompts now require source-anchored, sufficiently complete data and suppress a chart (present the gap-marked table instead) when a series is mostly undisclosed or mixes metric definitions. Tests: terminate preempts an in-flight execute and blocks reuse; block_network typo is rejected; SVG is rejected; dedup test now proves digest-keyed (not id-keyed) dedup.

The provider base creates these on session start via an idempotent mkdir -p (_prepare_workspace) and the runtime injects them as sandbox_workdir/sandbox_artifact_dir, so the directory the agent writes to and the directory the harvest scans always agree. This fixes charts being generated but never harvested (the report referenced an artifact that was written to a location the harvest did not scan). Also remove the hardcoded /sandbox/aiq-artifacts base path from the chart-generation skill example so the model writes to the injected per-job sandbox_artifact_dir instead of a shared base dir, and reinforce job-unique script names in the orchestrator/researcher prompts and skills. Add opt-in, provider-neutral CPU/memory resource limits (sandbox.resources), gated fail-closed by supports_resource_limits (Modal enforces; OpenShell declines). Trim verbose OpenShell file-transfer comments. Tests: job-scoped path helpers, workspace mkdir-on-create (best-effort), and runtime/provider path scoping; update provider-compliance and prompt-path assertions for the new behavior.

This collided with DeepAgents' filesystem semantics -- write_file refuses to overwrite an existing file, and edit_file is a search-and-replace that needs an exact old_string match. Whenever /shared/plan.json already existed (resumed or checkpointed jobs, or the planner revising), the LLM thrashed: edit_file -> "String not found" -> write_file -> "already exists" -> read_file -> regenerate -> edit_file -> ... In one long run this was 80 edit_file + 103 read_file = 183 of 446 tool calls (~40%), and it even spawned a /shared/plan_final.json workaround file. Now: the planner performs no filesystem I/O. PlanPersistenceMiddleware reads the planner's schema-validated ResearchPlan (response_format) and writes it to /shared/plan.json via the backend's overwrite-safe upload_files -- the same state channel the LLM write_file used, so downstream agents (orchestrator, researcher, writer) still read /shared/plan.json unchanged. This mirrors the existing run_research_batch -> ResearchNotes persistence pattern. planner.j2 and orchestrator.j2 now instruct the planner to simply return the structured plan and state that the runtime persists it. Result: 446 -> 132 tool calls on the same query; runtime trace showed "plan uploaded" x2 and edit_file x0. Files: custom_middleware.py (new PlanPersistenceMiddleware: persists on the planner model-call and after-agent seams, idempotent/overwrite-safe, failures logged not raised), factory.py (wires the middleware onto the planner subagent via context.backend), prompts/planner.j2, prompts/orchestrator.j2, tests/aiq_agent/agents/deep_researcher/test_custom_middleware.py. Requires: a model that supports automatic tool calling / structured outputs (response_format). gpt-5 family and nvidia/nvidia/nemotron-3-super-v3 work; the hub's Nemotron Nano deployments reject tool_choice=auto (HTTP 400: "'auto' tool choice requires --enable-auto-tool-choice and --tool-call-parser") and cannot drive the planner/researcher tool-calling agents. Sandbox tool-call visibility in the UI -------------------------------------- Sandbox-backed tool calls (execute, plus file ops outside /shared) are tagged with sandbox metadata on tool.start/tool.end SSE events and rendered with a "Sandbox" badge in the agent and tool-call cards. Touches jobs/callbacks.py, routes/jobs.py, and the frontend deep-research client, hooks, types, AgentCard, and ToolCallCard. Supporting changes ------------------ Sandbox runtime, artifact, and provider updates plus accompanying tests: sandbox/* (base, capabilities, config, registry, providers, artifacts), deepagents_runtime.py, jobs/runner.py, scripts/setup_openshell.sh, prompts/writer.j2 and researcher.j2, the chart-generation skill moved under skills/research/, and the related test suites.

The orchestrator.j2 Return-Answer step no longer tells the orchestrator to emit the report inline; it returns the writer marker and the runtime loads /shared/output.md. Also in this change ------------------- - CodeRabbit fixes: guard artifact post-processing so a verified report is not lost (agent.py); reject symlink escapes via workdir containment on artifact download (openshell.py); anchor the /shared prefix check (callbacks.py); gate chart lines on execution_enabled (orchestrator.j2); skip empty artifact_id in bulk download (aiq.py); fix fail-closed docstring (capabilities.py). - Align config_openshell.yml models with config_web_default_llamaindex.yml. - Update provider tests for the openshell default: provider is now a free string resolved by the registry, so unsupported providers fail in create_sandbox_backend rather than at config validation.

store.py: artifacts.created_at uses DateTime(timezone=True) so tz-aware timestamps work on PostgreSQL, not just SQLite. - base.py: re-check the terminated flag after a successful sandbox call so a concurrent terminate() that lands during a winning call surfaces cancellation. - MarkdownRenderer.spec: assert the caption renders in a (phrasing-safe), matching the renderer. - generate-pdf.ts: forward Authorization/idToken only when isAuthRequired(), matching the jobs proxy (no identity headers in anonymous mode). - Document the landlock best_effort tradeoff (drops FS confinement on hosts without Landlock; production must use hard_requirement) in the policy files and sandbox README. Reliability: - Add a guidance nudge to the writer/researcher prompts: each execute runs in a fresh shell, so cd does not persist; use absolute paths. Stops the no-op cd-only execute loop that burned tokens. OpenShell adapter to PyPI: - setup_openshell.sh installs langchain-nvidia-openshell==0.1.0 from PyPI instead of the git fork; bump default/min OpenShell SDK to 0.0.72 (adapter's tested floor); update usage text and the provider import hint and docs. CI: - Patch _create_sandbox_backend in test_init_with_custom_settings and test_require_sandbox_collection_with_sandbox_is_allowed so they no longer require the optional OpenShell adapter (default provider) to be installed. Deferred to follow-up (documented experimental): physical per-job OpenShell isolation and attach-time policy verification.
