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.

+# A7 — Conviction array  *(sub-organ of Eth-Int)*
+
+## 1. Component
+The lattice Eth-Int reads: the set of active principles with their convictions, **semantic-isomorphy
+tags**, and **stress-driven shift-rates**. The structural self that defines the agent's integrity,
+and the thing the SAE checks outputs against in the G1 stress loop.
+
+## 2. Status / certainty
+DESIGN-FIRST (extends today's flat principle list in `driver_ethical_integrity.R`). Tags + shift-rates
+are new — C2/C1.
+
+## 3. Language & location
+R · new module under `src/endocrine/` (e.g. `conviction_array.R`), consumed by A6.
+
+## 4. Does / does-not
+- **Does:** hold principle entries with conviction + isomorphy tags + per-entry shift-rate; expose the
+  **top convictions** for SAE matching (G1); apply hardening and stress-modulated shift-rate changes.
+- **Does-not:** evaluate cost (A6 does that) or detect opposition (SAE F2 does); it is the data + its update rules.
+
+## 5. Interface contract
+- **Entry:** `{ id, conviction(0..1), antithesis[], isomorphy_tags[], shift_rate }`.
+- `top_convictions(array, n) -> [entry]` (what SAE matches outputs against, G1 step 2).
+- `harden(array, ids, load) -> array'` · `set_shift_rate(array, delta_from_stress) -> array'`.
+- The **memory-derivative** rule: convictions are computed from memory-weighted entries (per arch §6) —
+  shape = "complex entries with memory-weighted shifting numerics," same family as PS+'s priors stray.
+
+## 6. Dependencies & stubs
+SAE (F2) feeds opposition events; stress endomotiv (A4/G1) feeds shift-rate deltas — *stub:* call
+`set_shift_rate` directly. Memory source (E2) for the derivative — *stub:* in-memory seed entries.
+
+## 7. Invariants / laws
+- **L1 (C2):** every conviction carries ≥1 **semantic-isomorphy tag** (so SAE can match outputs to it).
+- **L2 (C2):** under G1 stress, **shift-rates increase** (convictions move faster — harden or revise).
+- **L3 (C3):** hardening is bounded (→1.0, diminishing); convictions never exceed [0,1].
+- **L4 (C1):** the memory-derivative formula (how memory weights produce the live conviction) — undefined.
+
+## 8. Build steps
+1. Define the entry record + tag vocabulary; encode L1/L3 as tests. 2. Add shift-rate mechanics +
+the G1 hook (L2). 3. Define the memory-derivative (L4) once E2 storage lands. 4. Migrate A6 to use it.
+
+## 9. Tests
+`Rscript src/endocrine/test_conviction_array.R` (new) — L1 (tags present), L2 (stress↑ → shift-rate↑), L3 (bounds).
+
+## 10. Open items
+- **Isomorphy tag vocabulary** + how SAE matches outputs to it (C2, shared with F2/G1).
+- The **memory-derivative formula** (C1).
+- Shift-rate response curve to stress (C1).
