Extend the retired particulate-form defense to corpus navigation so the old dust prototype cannot return as the harness description.

+# 2026-07-26 — Keep the Thought effects lab named by its current scope
+
+```
+Type: log
+```
+
+## Tick finding
+
+A fresh audit of the effects-lab slice found that its owning spec, runtime
+window title, architecture mirrors, and shared renderer all describe the
+implemented Thought-only route/pool harness. The corpus navigation still
+called the page “Effects lab: dust and liquid,” however, preserving the
+retired particulate Exposure prototype as the reader's first description.
+
+This was the same mechanical drift class already promoted into the corpus
+gate for prose that names `misaligned-effects`. The gate did not cover a
+Markdown navigation label that linked directly to `effects-lab.md` without
+naming the binary.
+
+## Repair
+
+- `wiki/SUMMARY.md` now calls the harness “Effects lab: Thought routes and
+  pools.”
+- The living-spec criterion states that navigation labels are current
+  descriptions and may not preserve the retired dust/particulate name.
+- `tools/corpus_engine.py` rejects a particulate/dust label on a link to
+  `effects-lab.md`, with a fixture for the exact escaped form.
+
+No renderer, simulation, save, or gameplay behavior changed.
+
+## Defense
+
+`wiki/art/effects-lab.md` confines `misaligned-effects` to Thought routes and
+endpoint pools and places rigid Exposure custody records outside that fluid
+renderer. `wiki/process/meta.md` criterion 12 requires recurring superseded
+current-state claims to become executable corpus defenses. Updating the
+navigation and extending that existing defense prevents the retired visual
+ontology from returning through the corpus doorway.
