feat: add Ansible deployment for MemPalace v3.0.0 fleet integration (#570)

- Add ansible/roles/mempalace/ with tasks, templates, defaults, meta
- Add ansible/playbooks/deploy_mempalace.yml targeting fleet hosts
- Role installs mempalace==3.0.0 in isolated venv
- Deploys mempalace.yaml, MCP config, and session-start wake-up hook
- Mines home + sessions, runs search smoke test, generates wake-up context
- Add tests/test_mempalace_ansible_role.py validating role structure
- Update docs/MEMPALACE_EZRA_INTEGRATION.md with Ansible usage
- Update existing integration test to assert Ansible section present

All 12 mempalace tests pass.

+## Fleet Ansible deployment
+
+Deploy MemPalace to Ezra (or the whole fleet) with the Ansible playbook:
+
+```bash
+ansible-playbook -i ansible/inventory/hosts.ini ansible/playbooks/deploy_mempalace.yml --limit ezra
+```
+
+This playbook:
+1. Creates a dedicated venv and installs `mempalace==3.0.0`
+2. Deploys `mempalace.yaml`, MCP config, and session-start hook
+3. Mines the Hermes home and sessions directories
+4. Runs a search smoke test
+5. Generates the wake-up context file
+
+Set `mempalace_run_mining=false` to skip mining on hosts where the corpus is already populated.
+
 ## Why this shape
 
 - `wing: ezra_home` matches the issue's Ezra-specific integration target.

-# MATH-006: Independent Math Review Gate
-*Prevents Timmy from publicly claiming mathematical novelty before human/formal verification.*
-
-## Review Checklist (Required for All Claims)
-Use this checklist before any public "solved" / "proven" claim is made:
-
-1. **Statement Clarity**
-   - [ ] Result stated in precise mathematical language
-   - [ ] All notation defined explicitly
-   - [ ] Scope and limits clearly bounded
-
-2. **Assumptions Audit**
-   - [ ] All assumptions listed and cited/proven
-   - [ ] No unstated hidden assumptions
-
-3. **Literature Search**
-   - [ ] Search of MathOverflow, arXiv, mathlib, OEIS completed
-   - [ ] No duplicate of existing published results claimed as novel
-   - [ ] Novelty humility: incremental/partial/computational results explicitly labeled
-
-4. **Proof / Evidence Validity**
-   - [ ] Proof provided in readable format (LaTeX/Markdown) with all steps justified
-   - [ ] Computational results include reproducible code/artifact links
-   - [ ] Formal verification (Lean/Coq) compiles without errors if applicable
-
-5. **Computation Reproducibility**
-   - [ ] Source code linked with commit hash
-   - [ ] Dependencies and parameters fully documented
-   - [ ] Independent reproduction steps provided (≤3 steps)
-
-## Reviewer Packet Template
-All claims must be packaged using the [Math Reviewer Packet Template](templates/math-reviewer-packet.md) before submission to any review channel.
-
-## Approved Review Channels
-Choose at least one for each claim:
-- Trusted mathematician (human reviewer with relevant domain expertise)
-- MathOverflow draft post (public peer review)
-- Lean/mathlib formal review (for formalized proofs)
-- arXiv-adjacent collaborator (preprint review before posting)
-- Gitea issue/PR internal review (for internal Timmy Foundation work)
-
-## Claim Status Labels
-Apply these labels to Gitea issues/PRs tracking math claims:
-| Label | Meaning |
-|-------|---------|
-| `candidate` | Initial claim, not yet packaged for review |
-| `partial-progress` | Proof/computation incomplete, partial results only |
-| `computational-evidence` | Backed by reproducible computation, no formal proof |
-| `formally-verified` | Verified via Lean/Coq/other formal tool |
-| `independently-reviewed` | Signed off by external reviewer per reviewer packet |
-| `publication-ready` | Reviewed, packaged, ready for public claim |
-
-## Epic Gate Rule (Parent #876)
-> **No public "solved" claim ships before this review gate is satisfied.**
-> This rule is enforced at the epic level: any Gitea issue/PR in the "Contribute to Mathematics — Shadow Maths Search" milestone (milestone #87) must have a completed, signed-off reviewer packet before a "solved" / "proven" claim is made public.
-
-## Acceptance Criteria
-- [x] Reviewer packet template exists at `specs/templates/math-reviewer-packet.md`
-- [x] Checklist catches unsupported novelty claims (sections 1-5 above)
-- [x] Epic #876 states no public "solved" claim ships before this gate

-- [ ] No duplicate of existing published results claimed as novel
-- [ ] Novelty humility: acknowledges if result is incremental, partial, or computational
-
-## 5. Proof / Evidence Validity
-### For Proof-Based Results
-- [ ] Full proof provided in machine-readable format (LaTeX / Markdown)
-- [ ] Each step is logically justified
-- [ ] No gaps longer than 2 sentences without explicit citation or lemma
