-# 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

-# Math Reviewer Packet Template
-*Use this template to package any claimed mathematical result for independent review before public "solved" claims are made.*
-
-## 1. Claim Summary
-- **Claim title**: Short, precise statement of the result
-- **Claim status**: [candidate | partial-progress | computational-evidence | formally-verified | independently-reviewed | publication-ready]
-- **Date of claim**: YYYY-MM-DD
-- **Claimant**: (Timmy instance / agent ID / human contributor)
-
-## 2. Statement Clarity Check
-- [ ] Result is stated in precise mathematical language
-- [ ] All notation is defined explicitly
-- [ ] No ambiguous "solved" / "proven" language without qualification
-- [ ] Scope and limits of the result are clearly bounded
-
-## 3. Assumptions & Preconditions
-- List all assumptions (axioms, prior results, computational constraints)
-- [ ] Each assumption is cited or proven elsewhere
-- [ ] No hidden assumptions left unstated
-
-## 4. Literature Search
-- [ ] Prior work search conducted (MathOverflow, arXiv, mathlib, OEIS, relevant textbooks)
-- [ ] 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
-
-### For Computational Results
-- [ ] Code/artifact link provided (reproducible environment)
-- [ ] Random seeds / parameters fully documented
-- [ ] Output verified by independent script (if applicable)
-
-### For Formal Verification
-- [ ] Lean / Coq / other formal proof assistant file linked
-- [ ] Compiles without errors on standard toolchain
-
-## 6. Reproducibility Package
-- [ ] All source code used is linked (repo commit hash / Gitea issue/PR reference)
-- [ ] Dependencies listed with versions
-- [ ] Minimal reproduction steps provided (3 steps or fewer)
-
-## 7. Review Channel & Sign-off
-- **Selected review channel**: (trusted mathematician / MathOverflow draft / Lean/mathlib review / arXiv-adjacent collaborator / other)
-- **Reviewer identity**: (handle / name / affiliation)
-- **Review date**: YYYY-MM-DD
-- **Review outcome**: [APPROVED | REVISION REQUIRED | REJECTED]
-- **Reviewer notes**: (free text)
-
-## 8. Public Claim Checklist
-- [ ] Reviewer packet complete per above sections
-- [ ] Review sign-off obtained from chosen channel
-- [ ] No public "solved" / "proven" claim made before sign-off
-- [ ] Claim status label updated in relevant Gitea issue/PR
