 - **Agent Health** — context used vs set, subconscious alive/failed with the
   actual error, memory git state (dirty/ahead/behind), energy balance, todos,
   itinerary. Every item already exists as live state and is drawn nowhere.
-  Note: used-context has **no truthful source today** — `memory status` reports
-  no pressure figure (B-008), so this tab has a data dependency, not just a
-  drawing one.
+  ~~Note: used-context has **no truthful source today**~~ — **resolved
+  2026-08-12.** `7530d6d` made `ContentBlock::countable_text()` the exhaustive
+  authority, `f266136` named the wire fields (`tokens_used` / `context_limit`
+  were being conflated — the pill was printing the *limit* as the usage), and
+  r467 is installed and running. Patch 0007 landed the pill. The breakdown
+  endpoint `GET /v1/conversations/:id/tokens` already returns per-role figures
+  with **zero consumers** — that is the click-through.
+  **Group the breakdown by block kind, not role**: measured on a real thread it
+  is tool_result 43% / tool_use 31% / text 18% / reasoning 7%, and per-role
+  filing puts 74% of that under "assistant", which reads as the agent being
+  chatty and points at the wrong lever.
+- **Conversations list / instantiation selector** (Casey, 2026-08-12) — moves
+  into the pane. `Souveraine.newConversation()` already exists and is what
+  `/new` calls; `GET /v1/conversations` is the listing surface, sorted by
+  `updated_at`. Note there is **no conversation search anywhere** in the
+  codebase — 148 conversations for this agent alone — so a flat list will stop
+  scaling early. QMD (`tobi/qmd`, AUR) indexes markdown, which would want a
+  markdown projection with the JSONL staying authoritative.
 - **Reflection / subconscious** — her thread, her inbox, her failures.
 - **Anime/persona** — moves off the top level; it is a persona surface, not a
   system surface.
