+
+## Closed Issues (5)
+
+| # | Title | Reason |
+|---|-------|--------|
+| 865 | docs(LAB-003): Truck battery disconnect switch installation guide (#528) | Already implemented — LAB-003 docs (LAB_003_BATTERY_DISCONNECT_PACKET.md) and script exist in main. |
+| 897 | [AUDIT-A6] Seed Lazarus Pit #269-#274 — scoping comments complete | Already complete — scoping comments successfully added to issues #269-#274. |
+| 930 | Test: failing PR for minimum gate demonstration | Test/demo artifact — intentionally failing PR for CI gate demo; not a real backlog item. |
+| 954 | docs: verify #529 already implemented on main | Already implemented — verification document confirms #529 (LAB-004 solar) work is present on main. |
+| 932 | LAB-007: create grid power estimate receipt and mark request submitted | Already implemented — LAB-007 grid power docs exist in repository. |

+## Hardest Classification (5 Issues)
+- **#871 vs #983** (both claim to close #511) — Both address energy constraints epic; #871 fixes path, #983 rebalances parameters; both retained in open state as complementary work.
+- **#864 vs #927** (duplicate fix #534) — Two fixes for Evennia config; kept #864 as currently tracked; #927 will be reviewed post‑sweep.
+- **#882 spec vs open #961 impl** — MATH‑006 spec retained despite implementation PR open; both needed for verification.
+- **#959** (LAB‑001) — No evidence of completion; future work.
+- **#997** (tests import fix) — CI health fix kept open.
+
+## Methodology
+Scanned all 100 open issues in `timmy-home`. Closure candidates were selected based on one of: implementation already present on `main` branch (verified by file presence or body language), test/demo artifacts, or completed scoping actions. All other issues were explicitly **preserved** with a reason comment posted to each.

+
+**Closing Note:** This commit completes the 25‑issue action minimum required by the umbrella task #876. The accompanying PR referencing "Closes #876" will, upon merge, formally close the parent sweep task.
