# Summarise Ecosystem Results ## Priorities 1. Reproduce every retained source-attributable behavior with the exact environment used by the Actions run. 2. For every distinct source-attributable behavior change, produce the smallest provenance-preserving reproducer obtainable through the complete advanced-minimization workflow. 3. Eliminate every third-party import unless identified ty behavior depends on that library's identity or third-party search-path classification, and eliminate every unnecessary standard-library import. Retain an import only after verifying that neither removing it nor inlining its definitions preserves the underlying behavior. 4. Lead the report with new or meaningfully changed project failures, including intermittent severe failures, then cover stable diagnostic changes and fully minimized examples. 5. Keep execution, audit, and traceability bookkeeping out of the report. ## GitHub CLI Telemetry Prefix every direct or indirect `gh` invocation with `GH_TELEMETRY=false`, including `GH_TELEMETRY=false uv run --script scripts/collect_ty_ecosystem_run_metadata.py ...`. Require the same of subagents. Codex tool calls may start separate shells, so an `export` in an earlier call is insufficient. ## Deliverable Create `PR_<number>_ECOSYSTEM_SUMMARY.md` at the repository root by adapting [assets/report-template.md](assets/report-template.md). The finished artifact must be GitHub-flavored Markdown suitable for a GitHub comment, with each prose paragraph a...
