# Issue #004: Test + Bench Standards Audit & Proven Tests Repo

**Track:** CICD Optimization — Ultra-Zotta-Plan  
**Priority:** HIGH  
**Status:** TODO  
**Owner:** @hyperpolymath  
**Date:** 2026-06-05  

---

## Description

This issue covers:
1. **Audit** of existing test/bench standards across the estate
2. **Panic-Attack** integration for runtime safety
3. **Proven Tests Repo** creation using Idris2 for formal guarantees

---

## Part 1: Audit Existing Test Standards

### 1.1 Current State

**Standards repo location:** `standards/.github/workflows/` + `standards/templates/`

**Questions to answer:**
- [ ] Are test workflows applied estate-wide?
- [ ] Are there contradictions between repos?
- [ ] Are panic-attack tests integrated everywhere?
- [ ] Are benchmarks proven/safe?
- [ ] Do test workflows cover echo-type safety?

### 1.2 Inventory of Test Workflows

```bash
# Find all test-related workflows
find . -path "*/.github/workflows/*.yml" -exec grep -l "test\|bench" {} \; | sort | uniq
```

**Expected findings:**
- `rust-ci.yml` (includes `cargo test`)
- `elixir-ci.yml` (includes `mix test`)
- `test.yml` / `tests.yml` (various repos)
- `bench.yml` / `benchmarks.yml` (various repos)
- `panic-attack.yml` (if exists)

### 1.3 Contradictions Check

**Compare:**
- Rust test patterns across 5+ repos
- Elixir test patterns across 5+ repos
- Benchmark configurations
- Panic-attack integration depth

---

## Part 2: Panic-Attack Integration

### 2.1 Current State

**Panic-attack repo:** Likely in `panic-attack/` or `standards/`

**Patterns to detect:**
- [ ] Unsafe blocks (`unsafe { }`)
- [ ] Unwraps/expects (`.unwrap()`, `.expect()`)
- [ ] Integer overflows
- [ ] Race conditions (send/recv without proper synchronization)
- [ ] Memory safety issues
- [ ] Null pointer dereferences

### 2.2 Integration Tasks

#### Task 2.2.1: Add panic-attack to all Rust repos
- **Action:** Add panic-attack workflow to repos with `Cargo.toml`
- **Template:**
  ```yaml
  name: Panic Attack
  on: [push, pull_request]
  jobs:
    panic-attack:
      runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@v6
        - uses: hyperpolymath/panic-attack-action@main
  ```
- **Status:** TODO
- **Priority:** HIGH

#### Task 2.2.2: Configure panic-attack for estate-specific patterns
- **Echo-type safety:** Detect violations of echo-type invariants
- **Higher-order patterns:** Identity, projection, invariance, traversal
- **Custom rules:** Based on estate proofs
- **Status:** TODO
- **Priority:** HIGH

---

## Part 3: Proven Tests Repo (Idris2)

### 3.1 Repo Creation

**New repo:** `proven-tests-and-benches`

**Purpose:** Formal guarantees for test correctness using Idris2

```

### 3.2 Properties to Prove

#### Test Validity
```idris
-- A test is valid if it has a well-formed structure
TestValid : (t : Test) -> Type
TestValid t = 
  (Test.HasName t) ×
  (Test.HasInput t) × 
  (Test.HasExpectedOutput t)
```

#### Test Soundness
```idris
-- A test is sound if it catches what it claims to catch
TestSound : (t : Test) -> Prop
TestSound t = 
  ∀ input, 
    Test.Runs t input →
    (Test.Passes t input ↔ MeetsSpec input (Test.Expected t))
```

#### Test Safety
```idris
-- A test is safe if it cannot cause undefined behavior
TestSafe : (t : Test) -> Prop
TestSafe t = 
  ∀ input, 
    Test.Runs t input →
    ¬ (Crashes t input ∨ UndefinedBehavior t input)
```

#### Test Tamper-Proof
```idris
-- A test is tamper-proof if modifications are detectable
TestTamperProof : (t : Test) -> Prop
TestTamperProof t = 
  ∀ t', 
    t' ≠ t →
    DetectsTampering (Test.Signature t) (Test.Signature t')
```

#### Test Unpanickable
```idris
-- A test cannot panic
TestUnpanickable : (t : Test) -> Prop
TestUnpanickable t = 
  ∀ input, 
    Test.Runs t input →
    ¬ Panics t input
```

### 3.3 Echo-Type Specific Tests

#### Echo-Type Safety
```idris
-- Echo types preserve structure through transformations
echoTypeSafety : (T : Type) → (op : EchoOp T) → Prop
echoTypeSafety T op = 
  ∀ (x : T), 
    Let y = applyEchoOp op x in
    PreservesStructure x y
```

#### Identity Tests
```idris
-- Identity operations preserve value
identityPreservation : (T : Type) → (x : T) → Prop
identityPreservation T x = 
  identity T x = x
```

#### Projection Tests
```idris
-- Projections extract correct components
projectionCorrectness : (T : Type) → (p : Projection T) → Prop
projectionCorrectness T p = 
  ∀ (x : T), 
    Let y = project p x in
    ValidProjection p x y
```

#### Invariance Tests
```idris
-- Invariants are preserved through operations
invariancePreservation : (T : Type) → (inv : Invariant T) → Prop
invariancePreservation T inv = 
  ∀ (x : T) (op : Op T),
    inv x →
    inv (applyOp op x)
```

#### Traversal Tests
```idris
-- Traversals visit all elements correctly
traversalCompleteness : (T : Type) → (traverse : Traversal T) → Prop
traversalCompleteness T traverse = 
  ∀ (x : T), 
    Let visited = traverse x in
    AllElementsVisited x visited
```

#### Set Concept Tests
```idris
-- Set operations maintain set properties
setOperationCorrectness : (A : Type) → Prop
setOperationCorrectness A = 
  (SetUnionAssociative A) ×
  (SetIntersectionAssociative A) ×
  (SetDistributive A)
```

#### Interdimensional Transfer Tests
```idris
-- Transfers between dimensions preserve meaning
interdimensionalPreservation : (D1 D2 : Dimension) → Prop
interdimensionalPreservation D1 D2 = 
  ∀ (x : D1), 
    Let y = transfer D1 D2 x in
    Semantics.Preserved x y
```

## Part 4: Estate-Specific Test Patterns

### 4.1 Patterns to Cover

  push:
    branches: [main]
    paths:
      - 'proven-tests/**'
      - '**.idr'
  pull_request:
    branches: [main]
    paths:
      - 'proven-tests/**'
      - '**.idr'

jobs:
  idris-prove:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v6
      - uses: idris-lang/setup-idris2@v1
      - run: idris2 --build proven-tests.ipkg
      - run: idris2 --exec proven-tests-exec

  coq-prove:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v6
      - uses: coq-community/setup-coq@v1
      - run: make -C coq-proofs
