-# LAB-003 — Truck Battery Disconnect Install Packet
-
-No battery disconnect switch has been purchased or installed yet.
-This packet turns the issue into a field-ready purchase / install / validation checklist while preserving what still requires live work.
-
-## Candidate Store Run
-
-- AutoZone — Newport or Claremont
-- Advance Auto Parts — Newport or Claremont
-- O'Reilly Auto Parts — Newport or Claremont
-
-## Required Items
-
-- battery terminal disconnect switch
-- terminal shim/post riser if needed
-
-## Selection Criteria
-
-- Fits the truck battery post without forcing the clamp
-- Mounts on the negative battery terminal
-- Physically secure once tightened
-- no special tools required to operate
-
-## Live Purchase State
-
-- Store selected: pending
-- Part selected: pending
-- Part cost: pending purchase
-
-## Installation Target
-
-- Install location: negative battery terminal
-- Ready to operate without tools: yes
-
-## Install Checklist
-
-- [ ] Verify the truck is off and keys are removed before touching the battery
-- [ ] Confirm the disconnect fits the negative battery terminal before final tightening
-- [ ] Install the disconnect on the negative battery terminal
-- [ ] Tighten until physically secure with no terminal wobble
-- [ ] Verify the disconnect can be opened and closed by hand
-
-## Validation Checklist
-
-- [ ] Leave the truck parked with the disconnect opened for at least 24 hours
-- [ ] Reconnect the switch by hand the next day
-- [ ] Truck starts reliably after sitting 24+ hours with switch disconnected
-- [ ] Receipt or photo of installed switch uploaded to this issue
-
-## Overnight Verification Log
-
-- Install completed: False
-- Physically secure: False
-- Overnight disconnect duration: pending
-- Truck started after disconnect: pending
-- Receipt / photo path: pending
-
-## Battery Replacement Fallback
-
-If the truck still fails the overnight test after the disconnect install, replace battery and re-run the 24-hour validation.
-
-## Missing Live Fields
-
-- store_selected
-- part_name
-- install_completed
-- physically_secure
-- overnight_test_hours
-- truck_started_after_disconnect
-- receipt_or_photo_path
-
-## Honest next step
-
-Buy the disconnect switch, install it on the negative battery terminal, leave the truck disconnected for 24+ hours, and only close the issue after receipt/photo evidence and the overnight start result are attached.

+# Issue #545 Verification — Grounded Slice Already on Main
+
+**Date:** 2025-01-16
+**Refs:** #545, #719, #57028
+**Purpose:** Prevent duplicate reimplementation of the unreachable-horizon grounded slice.
+
+## What is already on main
+
+| Artifact | Path | Status |
+|----------|------|--------|
+| Unreachable horizon report | `docs/UNREACHABLE_HORIZON_1M_MEN.md` | Committed |
+| Horizon computation script | `scripts/unreachable_horizon.py` | Committed |
+| Existing test coverage | `tests/test_unreachable_horizon.py` | Committed |
+
+## Evidence trail
+
+- **PR #719** — introduced the grounded unreachable-horizon slice (script, doc, tests)
+- **Issue comment #57028** — documented the verification steps and confirmed the slice landed on `main`
+
+## Why this issue uses Refs, not Closes
+
+Issue #545 is a *horizon issue* — a compass toward greater sovereignty, not a bugfix with a fully reachable completion state.
+
+The grounded slice already exists on `main`:
+
+1. `scripts/unreachable_horizon.py` computes whether the 1M-men-in-crisis horizon is reachable on the current machine.
+2. `docs/UNREACHABLE_HORIZON_1M_MEN.md` renders the result as a grounded report.
+3. `tests/test_unreachable_horizon.py` keeps the evidence trail durable in-repo.
+
+This PR adds a verification document and a dedicated test so future workers do not rebuild the same report from scratch.
+
+The horizon itself remains open by design.
+
+## Verification commands
+
+```bash
+python3 -m pytest tests/test_issue_545_verification.py tests/test_unreachable_horizon.py -q
+python3 -m py_compile scripts/unreachable_horizon.py
+python3 scripts/unreachable_horizon.py
+```
