Suggested (not linked — for maintainer review)

• [aw]: Allow engine.model to be driven by an ADO pipeline variable / variable group #2035 (ADO variable-group-driven engine.model) and [agent-issue]: support declarative Azure DevOps pipeline variables in workflow source #2012 (declarative ADO pipeline variables) look related to each other (both extend pipeline-variable configurability) but neither clearly nests under an existing parent — worth a future umbrella if the theme grows.
• [agent-issue]: create-pull-request cannot target a repository from another Azure DevOps organisation #1934 (create-pull-request cross-org target) could arguably join [Parent] MCPG infrastructure and safe-output tooling improvements #1321 (MCPG/safe-output tooling) but it's a distinct cross-org auth concern, not clearly "broader vs narrower" than the existing parent's scope — left unlinked pending maintainer judgment.
• 🔴 Red Team Audit — High: Shell injection via runtimes.lean.toolchain #855 (shell injection in runtimes.lean.toolchain) is security-labeled like Proxy Stage 1 Azure DevOps reads without exposing SC_READ_TOKEN #1652 (Stage 1 ADO proxy) but they address unrelated attack surfaces; not linked.

Observations

• The backlog is already well-curated: 7 [Parent] umbrella issues exist ([Parent] Track agent runtime and execution pipeline improvements #1649, [Parent] Track and resolve recurring agentic workflow execution failures (non-rate-limit) #1549, [Parent] Track and resolve recurring AI-credits rate-limit failures in scheduled agentic workflows #1535, [Parent] Safe-output executor E2E test coverage and tool correctness #1428, [Parent] MCPG infrastructure and safe-output tooling improvements #1321, [Parent] Compiler internals and pipeline generation improvements (IR types, YAML gen, prompt decoupling) #1286, [Parent] Track and act on upstream dependency release-note action items (awf, mcpg, copilot-cli) #1283) but several had open children in the dataset that were not yet linked as GitHub sub-issues — this run closed that gap for 18 relationships across 5 parents.
• [Parent] Track and resolve recurring agentic workflow execution failures (non-rate-limit) #1549 and [Parent] Track and resolve recurring AI-credits rate-limit failures in scheduled agentic workflows #1535 (recurring workflow failures / rate-limit incidents) list sub-issues in their bodies (e.g. [aw] Bash Step Hygiene Auditor failed #1544, [aw] Issue Arborist hit AI credits rate limit #1515) that were not present in the current open, non-sub-issue dataset — likely already linked or closed, so no action was needed there.
• [Parent] Issue Arborist - Issue Group #1284 is a generic auto-generated "Issue Arborist" grouping parent with no body content beyond a template; left untouched as it's a different mechanism (workflow-managed group) from the manual umbrellas above.
