-# Issue #567 Verification
-
-## Status: ✅ ALREADY IMPLEMENTED ON MAIN
-
-Issue #567 asked for four things:
-1. an architecture doc at `evennia-mind-palace.md`
-2. a mapping of the 16 tracked Evennia issues to the mind-palace layers
-3. Milestone 1 proof: one room, one object, one mutable fact wired to Timmy's burn cycle
-4. a comment on the issue with proof of room entry injecting context
-
-All four are already present on `main` in a fresh clone of `timmy-home`.
-
-## Mainline Evidence
-
-### Repo artifacts already on main
-- `evennia-mind-palace.md`
-- `evennia_tools/mind_palace.py`
-- `scripts/evennia/render_mind_palace_entry_proof.py`
-- `tests/test_evennia_mind_palace.py`
-- `tests/test_evennia_mind_palace_doc.py`
-
-### Acceptance criteria check
-- Architecture doc exists at `evennia-mind-palace.md`
-- The 16 tracked Evennia issues are mapped in the issue-to-layer table inside `evennia-mind-palace.md`
-- Milestone 1 is implemented in `evennia_tools/mind_palace.py` with `Hall of Knowledge`, `The Ledger`, `MutableFact`, `BurnCycleSnapshot`, and deterministic room-entry rendering
-- The proof comment already exists on the issue as issue comment #56965
-
-## Historical trail
-- PR #711 attempted the issue and posted the room-entry proof comment
-- PR #711 was later closed unmerged, but the requested deliverables are present on `main` today and pass targeted verification from a fresh clone
-
-## Verification run from fresh clone
-
-Commands executed:
-- `python3 -m pytest tests/test_evennia_layout.py tests/test_evennia_telemetry.py tests/test_evennia_training.py tests/test_evennia_mind_palace.py tests/test_evennia_mind_palace_doc.py -q`
-- `python3 -m py_compile evennia_tools/mind_palace.py scripts/evennia/render_mind_palace_entry_proof.py`
-- `python3 scripts/evennia/render_mind_palace_entry_proof.py`
-
-Observed result:
-- all targeted Evennia mind-palace tests passed
-- the Python modules compiled cleanly
-- the proof script emitted the expected `ENTER Hall of Knowledge` packet with room context, ledger fact, and Timmy burn-cycle focus
-
-## Recommendation
-
-Close issue #567 as already implemented on `main`.
-This verification PR exists only to document the evidence trail cleanly and close the stale issue without re-implementing the already-landed architecture.
