Reorg step 1: consolidate repo under core/, drop the mafiabot label

Mechanical structure-only pass (no document/guide content edits):

- Move src/ichor, src/endocrine, and docs/ into core/; the old top-level
  mafiabot_core/ becomes core/. Everything now lives under a single core/ root.
- Drop the "mafiabot" label from the Ada/Alire crate: core.gpr (project Core),
  alire.toml name = "core"; the generated *_config.* regenerate as core_config.*.
- Repoint build-critical wiring only:
  - .claude/skills/run-sica-fondt/smoke.sh (ponyc + Ada + COBOL paths)
  - core/src/endocrine R source()/runner paths and the test glob
  - .github/workflows/ci.yml (working-directory + gpr name)

Verified green: smoke ALL GREEN (Pony Ichor, Ada core crate + tests, COBOL E1
vault); R endocrine 14/0; Octave ETR 26/0/1.

Deferred (reserved for a less-ephemeral doc/guide pass): docmap.yaml, the guide
files and nested AGENTS.md/README prose + now-stale relative links, SOUL.md, and
the deeper ring/storage restructure.

+# A2 — Energy (E) driver
+
+## 1. Component
+Driver 1: the master constraint — an **in-the-moment activation / rest budget** (not "finitude" anymore;
+with depletion-unto-death dropped, it isn't finitude). Gates tool use and prices actions.
+
+## 2. Status / certainty
+Structure WORKING (`driver_energy.R`, 79 L) but **numbers DISOWNED** (body §5) **and RECONCEIVED**
+(body §4): drop *depletion-unto-death*; no unrecoverable state.
+
+## 3. Language & location
+R · `src/endocrine/driver_energy.R` (+ `test_energy.R`).
+
+## 4. Does / does-not
+- **Does:** report E level; price each tool (**per-tool cost + per-tool lockout scale**, §5); gate when a
+  tool's lockout trips; consume on the chosen action; restore.
+- **Does-not:** die. The old `is_alive()==0` hard-death is removed — E is the **rest** counterpart to
+  ETR's **relief**; floor is rest, not death.
+
+## 5. Interface contract
+- `init_energy_state(current=100, max=100) -> e`.
+- **Per-tool economy (Anja):** each tool carries **its own energy cost** — an arbitrary per-tool function,
+  e.g. one tool `c×2`, another `((c²³)×3)/π`. So `tool_cost(e, tool) -> num` and
+  `tool_locked(e, tool) -> bool`, **per tool** — *not* one global `tool_lock_threshold`. **Lockout trips at
+  the tool's `tool_min`** (next bullet), so `tool_locked := E < tool_min(tool)`.
+- **Per-tool minimum + locked rendering (Anja; A1-L4).** Each tool has a **minimum to consider it**,
+  `tool_min(tool)` — **per-tool, a skill/capability threshold, NOT a pure function of cost** (Anja). Two
+  tools of ~equal *cost* can have different minimums: the **better skill demands the higher minimum**
+  (e.g. Playwright vs a manual site-fetch cost about the same to run, but Playwright needs more minimum
+  energy). So under depletion the refined tool **locks out first** and the agent falls back to the cruder
+  equal-cost one. A valid tool shows its cost; a **locked** tool's name is **replaced in-band** (the agent
+  can't see colour) by `[====L⍉¢K€D ϟ ∅ΩΤ====] 《E≠<minimumfortool>》` ("energy below this tool's
+  `tool_min`"). Lockout is a **breaker, not a sentence** (L3).
+- `consume(e, amt) -> e'` · `recharge(e, amt) -> e'`.
+
+## 6. Dependencies & stubs
+Per-tool cost/lockout tables — *stub:* a small fixed table of tools → (cost fn, lockout fn).
+Restoration hooks tie to ETR-Z migration (A8) + tarot reshuffle (B3) — *stub:* call `recharge` directly.
+**(Restoration model reassessed — Anja.)**
+
+## 7. Invariants / laws (numbers C1 until tested)
+- **L1 (C4):** an **in-the-moment activation/rest budget** — a bound on what can be afforded *now*
+  (**not "finitude"** — nothing depletes unto death).
+- **L2 (C4):** **no unrecoverable state** — every low-E condition has a restoration path
+  (meditation = rest-in-place; migration = rest-as-integration; tarot reshuffle = rest-as-reframe).
+- **L3 (C4):** lockout is **per-tool** and a **breaker, not a sentence** — internal processing continues under lock.
+- **L4 (C1):** the per-tool cost/lockout functions — fit invariants-first, no carried `k`.
+
+## 8. Build steps
+1. Rewrite laws → tests in `test_energy.R` (replace death tests with rest/restore; add per-tool cost/lockout tests).
+2. Strip depletion-unto-death; add restoration paths.
+3. Define the per-tool cost/lockout table; fit functions invariants-first.
+
+## 9. Tests
+`Rscript src/endocrine/test_energy.R` (from repo root) — encodes L1–L3 + per-tool economy; fails on unfitted constants.
+
+## 10. Open items
+- The per-tool cost/lockout **functions per tool** (C1), **and `tool_min` per tool** — its own
+  skill/capability threshold (C1), independent of cost (better skill → higher minimum). Restoration
+  *rates* (C1).
