Suggested (not linked — for maintainer review)

• Proxy Stage 1 Azure DevOps reads without exposing SC_READ_TOKEN #1652 (Proxy Stage 1 ADO reads without exposing SC_READ_TOKEN) reads as a large security epic; no obvious existing parent, and it doesn't yet have 5+ concrete sub-tasks in the open backlog to warrant a new parent.
• Feature request: first-class TLA+ / TLC (Java) runtime support #1222 (TLA+/TLC runtime) and [agent-issue]: support weekday-only fuzzy schedules and cron parity #1965 (weekday fuzzy schedules) are standalone feature requests without related open siblings — no cluster to form.
• maintainer away #1912 ("maintainer away") and [aw] Detection Runs #793/[aw] No-Op Runs #13 ("[aw] Detection/No-Op Runs") are operational/status issues, not epics.

Observations

• Several umbrella parents ([Parent] Track agent runtime and execution pipeline improvements #1649, [Parent] Compiler internals and pipeline generation improvements (IR types, YAML gen, prompt decoupling) #1286, [Parent] MCPG infrastructure and safe-output tooling improvements #1321, [Parent] Safe-output executor E2E test coverage and tool correctness #1428, [Parent] Track and resolve recurring AI-credits rate-limit failures in scheduled agentic workflows #1535, [Parent] Track and act on upstream dependency release-note action items (awf, mcpg, copilot-cli) #1283) already existed from prior Issue Arborist runs; this run mainly caught newer orphaned issues ([agent-issue]: Gateway-managed, auto-refreshed Azure federated token file for user-defined MCP servers #1964, refactor(engine): emit typed install steps instead of YAML strings #1834, refactor(compile): unify AzureCLI@2 token-mint steps behind a shared typed helper #1378, [aw] Issue Arborist hit AI credits rate limit #1950, Reject unwireable cross-job provider-env macros on engine.env (follow-up to #1372) #1375) that had accumulated since those parents were last updated and attached them to the matching theme.
• No new 5+-issue orphan cluster without an existing parent was found this run — the backlog's major recurring themes (MCPG, IR/compiler internals, safe-output E2E, rate-limit incidents, dependency release notes) are already tracked.
