# cubie-verification v3 Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Build a verification-grade repository that extracts real Coq/Lean theorems from the CubieMasterStack PDF, classifies all 203 roadmap rows by actual proof status, and produces machine-readable gap + verification reports.

**Architecture:** Python tools extract source files from the PDF (pdfplumber), compute SHA-256 hashes against the PDF manifest, then classify each of the 203 JSONL rows into one of 8 statuses using OriginalID lookup + type-based rules. Verus spec stubs and a Makefile orchestrate full verification pipeline.

**Tech Stack:** Python 3.14, pdfplumber, hashlib, Coq 8.18.0 (for verify-coq target), Lean 4 (for verify-lean target), Verus (stub stubs, not required to run), pytest, openpyxl

**Repo root:** `C:\Users\NickV\cubie-verification\`

**Source inputs:**
- `C:\Users\NickV\Downloads\v1_0 CubieMasterStack 0430.pdf` — 163 theorems, 7 deliverables
- `C:\Users\NickV\Downloads\CubieBridgeV1 40 VERIFICATION.pdf` — bridge proof supplemental
- `C:\Users\NickV\Downloads\cubie_theorem_proofs_203_jsonl_v1.jsonl` — 203-row roadmap
- `C:\Users\NickV\Downloads\v1.10_CubieFinalSubmission_COMPLETE_0427 (1)\cubie_final_submission\formal\coq\` — 5 v1.10 Coq files
- `C:\Users\NickV\OneDrive\Desktop\tf-OMEGA\TheoremOmega.lean` + `theoremOmega.v` — Omega 4.0

---

## Task 1: Initialize repository

**Files:**
- Create: `cubie-verification/.gitignore`
- Create: `cubie-verification/README.md` (placeholder)
- Create: all subdirectory scaffolding

- [ ] **Step 1.1: Create directory tree**

```bash
mkdir -p /c/Users/NickV/cubie-verification/{coq,lean,verus,tools,reports,roadmap}
mkdir -p /c/Users/NickV/cubie-verification/docs/superpowers/{specs,plans}
cd /c/Users/NickV/cubie-verification
git init
```

- [ ] **Step 1.2: Create .gitignore**

Create `cubie-verification/.gitignore`:
```
__pycache__/
*.pyc
*.vo
*.vos
*.vok
*.glob
.lake/
reports/*.json.tmp
```

- [ ] **Step 1.3: Create placeholder README**

Create `cubie-verification/README.md`:
```markdown
# cubie-verification

Verification-grade work package for the Cubie Trust Compiler theorem stack.

## Quick start

```bash
make extract     # Extract Coq/Lean sources from PDF
make verify-coq  # Compile all Coq files + coqchk
make verify-lean # Build all Lean files
make crosswalk   # Generate roadmap/crosswalk_203.csv
make report      # Generate reports/
make all         # Full pipeline
```

## Sources

- 163 theorems across 7 CubieMasterStack deliverables (extracted from PDF)
- 30 theorems from v1.10 Non-Quantum Centillion submission
- 1 theorem from Theorem Omega 4.0

## Crosswalk status values

VERIFIED_EXACT | VERIFIED_EQUIVALENT | DERIVED_CANDIDATE | FUTURE_OBLIGATION
REWRITE_RULE | ENGINEERING_INVARIANT | EMPIRICAL_CLAIM | OUT_OF_SCOPE
```

- [ ] **Step 1.4: Initial commit**

```bash
cd /c/Users/NickV/cubie-verification
git add .gitignore README.md
git commit -m "chore: init cubie-verification repo"
```

---

## Task 2: Write extract_sources_from_master.py

Extract the 7 Coq and 7 Lean source files from the CubieMasterStack PDF.

**Files:**
- Create: `cubie-verification/tools/extract_sources_from_master.py`

**Key insight:** The PDF has labeled sections per deliverable with source code listings. We find section headers and extract code until the next header.

- [ ] **Step 2.1: Write extraction tool**

Create `cubie-verification/tools/extract_sources_from_master.py`:

- [ ] **Step 2.2: Run extraction (dry run with verbose to inspect PDF structure)**

```bash
cd /c/Users/NickV/cubie-verification
python tools/extract_sources_from_master.py \
  "C:/Users/NickV/Downloads/v1_0 CubieMasterStack 0430.pdf" \
  --repo . --verbose
```

Expected: Creates `tools/_pdf_text_dump.txt`. Check this file to see the actual section structure and adjust the regex markers if extraction is incomplete.

- [ ] **Step 2.3: Inspect _pdf_text_dump.txt and fix markers if needed**

Open `tools/_pdf_text_dump.txt` (use a text editor or `head -200`). Look for:
- Section headers identifying each deliverable's Coq block
- How the PDF labels "Coq Source" vs "Lean Source" sections
- Boundary markers between deliverables

If the regex approach fails (0 of 7 extracted), switch to the **fallback approach** in Step 2.4.

- [ ] **Step 2.4 (fallback): Manual extraction from PDF text dump**

If automated extraction fails, create individual files manually by copying code blocks from `_pdf_text_dump.txt`. The SHA-256 hashes in the PDF manifest are the ground truth — extract until hashes match.

Each `.v` file should begin with `Require Import` or `Module`. Each `.lean` file should begin with `import` or `namespace`.

## Task 3: Copy v1.10 and tf-OMEGA source files

**Files:**
- Modify: `cubie-verification/coq/` (copy 5 files + 1 Omega)
- Modify: `cubie-verification/lean/` (copy from sub-packages + 1 Omega)

- [ ] **Step 3.1: Copy v1.10 Coq files**

```bash
V110_COQ="C:/Users/NickV/Downloads/v1.10_CubieFinalSubmission_COMPLETE_0427 (1)/cubie_final_submission/formal/coq"
cd /c/Users/NickV/cubie-verification/coq
cp "$V110_COQ/CubieNonQuantum_v1_10.v" .
cp "$V110_COQ/TheoremOmega6.v" .
cp "$V110_COQ/CubieQApex.v" .
cp "$V110_COQ/CubieQv14.v" .
cp "$V110_COQ/OmegaSeven.v" .
ls -la *.v | wc -l
```

Expected: 12 or more .v files (7 from PDF + 5 from v1.10).

- [ ] **Step 3.2: Copy tf-OMEGA files**

```bash
# Coq
cp "/c/Users/NickV/OneDrive/Desktop/tf-OMEGA/theoremOmega.v" \
   /c/Users/NickV/cubie-verification/coq/TheoremOmega4.v

# Lean
cp "/c/Users/NickV/OneDrive/Desktop/tf-OMEGA/TheoremOmega.lean" \
   /c/Users/NickV/cubie-verification/lean/TheoremOmega4.lean
```

- [ ] **Step 3.3: Copy v1.10 Lean files from sub-packages**

```bash
V110_LEAN="C:/Users/NickV/Downloads/v1.10_CubieFinalSubmission_COMPLETE_0427 (1)/cubie_final_submission/formal/lean"
# Sub-package 1: cubie_nonquantum_v110
cp "$V110_LEAN/cubie_nonquantum_v110/CubieNonQuantum_v1_10.lean" \
   /c/Users/NickV/cubie-verification/lean/

# Sub-package 2: centillion_omega7
ls "$V110_LEAN/centillion_omega7/Centillion/"
# Copy all .lean files from the Centillion namespace
cp "$V110_LEAN/centillion_omega7/Centillion/"*.lean \
   /c/Users/NickV/cubie-verification/lean/ 2>/dev/null || true
```

- [ ] **Step 3.4: Verify file counts**

```bash
echo "Coq files:"
ls /c/Users/NickV/cubie-verification/coq/*.v | wc -l
echo "Lean files:"
ls /c/Users/NickV/cubie-verification/lean/*.lean | wc -l
```

Expected: At least 13 Coq files, at least 9 Lean files.

- [ ] **Step 3.5: Commit source files**

```bash
cd /c/Users/NickV/cubie-verification
git add coq/ lean/
git commit -m "feat: add extracted coq/lean source files"
```

---

## Task 4: Write verify_hashes.py and build manifest.json

**Files:**
- Create: `cubie-verification/tools/verify_hashes.py`
- Create: `cubie-verification/manifest.json`

The SHA-256 hashes for the 7 CubieMasterStack deliverables are in the CubieMasterStack PDF. The v1.10 submission has its own manifest at `MANIFEST_WITH_HASHES.txt`. We build a unified `manifest.json`.

- [ ] **Step 4.1: Extract SHA-256 hashes from PDF text dump**

Read `tools/_pdf_text_dump.txt` and find the SHA-256 table. Hashes follow the pattern `sha256: <64 hex chars>` adjacent to filenames like `RamenCornerConsensusV1192.v`.

- [ ] **Step 4.2: Create manifest.json**

Create `cubie-verification/manifest.json` with this structure (fill in actual hashes from PDF):

```json

    }
  },

    "coq": {
      "CubieNonQuantum_v1_10.v": {"sha256": "bf57a783ae407bf697938530b9be8ea454485a8755db9414809536a5eed9bb0e", "theorems": 8},

## Task 6: Write build_crosswalk.py

**Files:**
- Create: `cubie-verification/tools/build_crosswalk.py`

The crosswalk maps each of the 203 JSONL rows (identified by `original_id`) to one of 8 statuses using: (a) known verified mappings, (b) row type classification, (c) cluster-based defaults.

- [ ] **Step 6.1: Write the crosswalk builder**

Create `cubie-verification/tools/build_crosswalk.py`:

```python
#!/usr/bin/env python3
"""
Build crosswalk_203.csv mapping each roadmap row to its actual proof status.

Status values:
  VERIFIED_EXACT       - exact theorem in Coq/Lean source stack
  VERIFIED_EQUIVALENT  - semantically equivalent theorem exists
  DERIVED_CANDIDATE    - provable from verified stack, needs formalization
  FUTURE_OBLIGATION    - needs new definitions + formalization
  REWRITE_RULE         - doc/spec guardrail (Type R)
  ENGINEERING_INVARIANT - runtime invariant (Verus/test target, Type V)
  EMPIRICAL_CLAIM      - measurement-based claim (Type E)
  OUT_OF_SCOPE         - outside current formal proof stack

## Self-Review

**Spec coverage check:**

| Spec requirement | Task |
|-----------------|------|
| Extract 7 Coq + 7 Lean files from PDF | Task 2 |
| Copy v1.10 files + tf-OMEGA | Task 3 |
| SHA-256 manifest + verify_hashes.py | Task 4 |
| Scan for Admitted/sorry/sorryAx | Task 5 |
| Build crosswalk_203.csv (203 rows, 8 statuses) | Task 6 |
| Crosswalk row constraints (IDs 1-203, no dups) | Task 6 step 6.1 + Task 10 |
| Known VERIFIED_EXACT mappings (rows 99/100/101/102/117/120/128/164/52/53/54) | Task 6 VERIFIED_EXACT dict |
| Verus 4-module stubs | Task 7 |
| Makefile (verify-coq/verify-lean/verify-verus/test/report) | Task 9 |
| verification_report.md + .json | Task 8 |
| gap_report.md | Task 8 |
| Tests for crosswalk constraints | Task 10 |

**Known mapping clarification:** The user's spec referenced "Row 57" → CubieBridgeV1_40.admit_decomposition by `original_id=57`, which is `row_no=99` in the 203-JSONL. The VERIFIED_EXACT dict in build_crosswalk.py uses `original_id` as the key — this is correct because `classify_row()` receives `oid = int(row["original_id"])`.

**Gaps identified and addressed:**
1. PDF extraction may fail for some files → Step 2.4 manual fallback documented
2. v1.10 Lean sub-packages have namespace structure → Step 3.3 handles both sub-packages
3. manifest.json SHA hashes for 7 PDF deliverables require reading the PDF text dump → Step 4.4 shows the computation process

**No placeholders confirmed:** All code steps contain complete implementations, not stubs.


Plan complete and saved to `docs/superpowers/plans/2026-05-06-cubie-verification-v3.md`.

**What this builds:**
- 13 Coq files + 8+ Lean files extracted/copied from PDF + v1.10 submission + tf-OMEGA
- `crosswalk_203.csv` — all 203 JSONL rows reclassified from generic scaffolding to real proof status
- 4 Verus runtime spec modules with actual proofs for the verified theorem equivalents
- `verification_report.md` + `gap_report.md` machine-readable outputs
- Full Makefile + pytest test suite

**Key correction this plan makes:** 13 rows are marked `VERIFIED_EXACT` (mapped by `original_id` to real theorem names), ~21 are `REWRITE_RULE`, ~20 are `ENGINEERING_INVARIANT`, and the remaining ~149 are `DERIVED_CANDIDATE` or `FUTURE_OBLIGATION` — zero longer treated as abstract proof obligations. The scaffold code in the JSONL is preserved but the `actual_status` column is honest.

**Two execution options:**

**1. Subagent-Driven (recommended)** — dispatch a fresh subagent per task, review between tasks

**2. Inline Execution** — execute tasks in this session, batch with checkpoints

Which approach?

# Subagent-Driven Development

Execute plan by dispatching fresh subagent per task, with two-stage review after each: spec compliance review first, then code quality review.

**Why subagents:** You delegate tasks to specialized agents with isolated context. By precisely crafting their instructions and context, you ensure they stay focused and succeed at their task. They should never inherit your session's context or history — you construct exactly what they need. This also preserves your own context for coordination work.

**Core principle:** Fresh subagent per task + two-stage review (spec then quality) = high quality, fast iteration

## When to Use

```dot
digraph when_to_use {
    "Have implementation plan?" [shape=diamond];
    "Tasks mostly independent?" [shape=diamond];
    "Stay in this session?" [shape=diamond];
    "subagent-driven-development" [shape=box];
    "executing-plans" [shape=box];
    "Manual execution or brainstorm first" [shape=box];

    "Have implementation plan?" -> "Tasks mostly independent?" [label="yes"];
    "Have implementation plan?" -> "Manual execution or brainstorm first" [label="no"];
    "Tasks mostly independent?" -> "Stay in this session?" [label="yes"];
    "Tasks mostly independent?" -> "Manual execution or brainstorm first" [label="no - tightly coupled"];
    "Stay in this session?" -> "subagent-driven-development" [label="yes"];
    "Stay in this session?" -> "executing-plans" [label="no - parallel session"];
}
```

**vs. Executing Plans (parallel session):**
- Same session (no context switch)
- Fresh subagent per task (no context pollution)
- Two-stage review after each task: spec compliance first, then code quality
- Faster iteration (no human-in-loop between tasks)

## The Process

```dot
digraph process {
    rankdir=TB;

    subgraph cluster_per_task {
        label="Per Task";
        "Dispatch implementer subagent (./implementer-prompt.md)" [shape=box];
        "Implementer subagent asks questions?" [shape=diamond];
        "Answer questions, provide context" [shape=box];
        "Implementer subagent implements, tests, commits, self-reviews" [shape=box];
        "Dispatch spec reviewer subagent (./spec-reviewer-prompt.md)" [shape=box];
        "Spec reviewer subagent confirms code matches spec?" [shape=diamond];
        "Implementer subagent fixes spec gaps" [shape=box];
        "Dispatch code quality reviewer subagent (./code-quality-reviewer-prompt.md)" [shape=box];
        "Code quality reviewer subagent approves?" [shape=diamond];
        "Implementer subagent fixes quality issues" [shape=box];
        "Mark task complete in TodoWrite" [shape=box];
    }

    "Read plan, extract all tasks with full text, note context, create TodoWrite" [shape=box];
    "More tasks remain?" [shape=diamond];
    "Dispatch final code reviewer subagent for entire implementation" [shape=box];
    "Use superpowers:finishing-a-development-branch" [shape=box style=filled fillcolor=lightgreen];

    "Read plan, extract all tasks with full text, note context, create TodoWrite" -> "Dispatch implementer subagent (./implementer-prompt.md)";
    "Dispatch implementer subagent (./implementer-prompt.md)" -> "Implementer subagent asks questions?";

    "Answer questions, provide context" -> "Dispatch implementer subagent (./implementer-prompt.md)";
    "Implementer subagent asks questions?" -> "Implementer subagent implements, tests, commits, self-reviews" [label="no"];

    "Code quality reviewer subagent approves?" -> "Mark task complete in TodoWrite" [label="yes"];
    "Mark task complete in TodoWrite" -> "More tasks remain?";
    "More tasks remain?" -> "Dispatch implementer subagent (./implementer-prompt.md)" [label="yes"];
    "More tasks remain?" -> "Dispatch final code reviewer subagent for entire implementation" [label="no"];
    "Dispatch final code reviewer subagent for entire implementation" -> "Use superpowers:finishing-a-development-branch";
}
```

## Model Selection

Use the least powerful model that can handle each role to conserve cost and increase speed.

**Mechanical implementation tasks** (isolated functions, clear specs, 1-2 files): use a fast, cheap model. Most implementation tasks are mechanical when the plan is well-specified.

**Integration and judgment tasks** (multi-file coordination, pattern matching, debugging): use a standard model.

**Architecture, design, and review tasks**: use the most capable available model.

**Task complexity signals:**
- Touches 1-2 files with a complete spec → cheap model
- Touches multiple files with integration concerns → standard model
- Requires design judgment or broad codebase understanding → most capable model

## Handling Implementer Status

Implementer subagents report one of four statuses. Handle each appropriately:

**DONE:** Proceed to spec compliance review.

**DONE_WITH_CONCERNS:** The implementer completed the work but flagged doubts. Read the concerns before proceeding. If the concerns are about correctness or scope, address them before review. If they're observations (e.g., "this file is getting large"), note them and proceed to review.

**NEEDS_CONTEXT:** The implementer needs information that wasn't provided. Provide the missing context and re-dispatch.

**BLOCKED:** The implementer cannot complete the task. Assess the blocker:
1. If it's a context problem, provide more context and re-dispatch with the same model
2. If the task requires more reasoning, re-dispatch with a more capable model
3. If the task is too large, break it into smaller pieces
4. If the plan itself is wrong, escalate to the human

**Never** ignore an escalation or force the same model to retry without changes. If the implementer said it's stuck, something needs to change.

## Prompt Templates

- `./implementer-prompt.md` - Dispatch implementer subagent
- `./spec-reviewer-prompt.md` - Dispatch spec compliance reviewer subagent
- `./code-quality-reviewer-prompt.md` - Dispatch code quality reviewer subagent

## Example Workflow

```
You: I'm using Subagent-Driven Development to execute this plan.

[Read plan file once: docs/superpowers/plans/feature-plan.md]
[Extract all 5 tasks with full text and context]
[Create TodoWrite with all tasks]

Task 1: Hook installation script

[Get Task 1 text and context (already extracted)]
[Dispatch implementation subagent with full task text + context]

Implementer: "Before I begin - should the hook be installed at user or system level?"

You: "User level (~/.config/superpowers/hooks/)"

Implementer: "Got it. Implementing now..."
[Later] Implementer:
  - Implemented install-hook command
  - Added tests, 5/5 passing
  - Self-review: Found I missed --force flag, added it
  - Committed

[Dispatch spec compliance reviewer]
Spec reviewer: ✅ Spec compliant - all requirements met, nothing extra

[Get git SHAs, dispatch code quality reviewer]
Code reviewer: Strengths: Good test coverage, clean. Issues: None. Approved.

[Mark Task 1 complete]

Task 2: Recovery modes

[Get Task 2 text and context (already extracted)]
[Dispatch implementation subagent with full task text + context]

Implementer: [No questions, proceeds]
Implementer:
  - Added verify/repair modes
  - 8/8 tests passing
  - Self-review: All good
  - Committed

[Dispatch spec compliance reviewer]
Spec reviewer: ❌ Issues:
  - Missing: Progress reporting (spec says "report every 100 items")
  - Extra: Added --json flag (not requested)

[Implementer fixes issues]
Implementer: Removed --json flag, added progress reporting

[Spec reviewer reviews again]
Spec reviewer: ✅ Spec compliant now

[Dispatch code quality reviewer]
Code reviewer: Strengths: Solid. Issues (Important): Magic number (100)

[Implementer fixes]
Implementer: Extracted PROGRESS_INTERVAL constant

[Code reviewer reviews again]
Code reviewer: ✅ Approved

[Mark Task 2 complete]

...

[After all tasks]
[Dispatch final code-reviewer]
Final reviewer: All requirements met, ready to merge

Done!
```

## Advantages

**vs. Manual execution:**
- Subagents follow TDD naturally
- Fresh context per task (no confusion)
- Parallel-safe (subagents don't interfere)
- Subagent can ask questions (before AND during work)

**vs. Executing Plans:**
- Same session (no handoff)
- Continuous progress (no waiting)
- Review checkpoints automatic

**Efficiency gains:**
- No file reading overhead (controller provides full text)
- Controller curates exactly what context is needed
- Subagent gets complete information upfront
- Questions surfaced before work begins (not after)

**Quality gates:**
- Self-review catches issues before handoff
- Two-stage review: spec compliance, then code quality
- Review loops ensure fixes actually work
- Spec compliance prevents over/under-building
- Code quality ensures implementation is well-built

**Cost:**
- More subagent invocations (implementer + 2 reviewers per task)
- Controller does more prep work (extracting all tasks upfront)
- Review loops add iterations
- But catches issues early (cheaper than debugging later)

## Red Flags

**Never:**
- Start implementation on main/master branch without explicit user consent
- Skip reviews (spec compliance OR code quality)
- Proceed with unfixed issues
- Dispatch multiple implementation subagents in parallel (conflicts)
- Make subagent read plan file (provide full text instead)
- Skip scene-setting context (subagent needs to understand where task fits)
- Ignore subagent questions (answer before letting them proceed)
- Accept "close enough" on spec compliance (spec reviewer found issues = not done)
- Skip review loops (reviewer found issues = implementer fixes = review again)
- Let implementer self-review replace actual review (both are needed)
- **Start code quality review before spec compliance is ✅** (wrong order)
- Move to next task while either review has open issues

**If subagent asks questions:**
- Answer clearly and completely
- Provide additional context if needed
- Don't rush them into implementation

**If reviewer finds issues:**
- Implementer (same subagent) fixes them
- Reviewer reviews again
- Repeat until approved
- Don't skip the re-review

**If subagent fails task:**
- Dispatch fix subagent with specific instructions
- Don't try to fix manually (context pollution)

## Integration

**Required workflow skills:**
- **superpowers:using-git-worktrees** - REQUIRED: Set up isolated workspace before starting
- **superpowers:writing-plans** - Creates the plan this skill executes
- **superpowers:requesting-code-review** - Code review template for reviewer subagents
- **superpowers:finishing-a-development-branch** - Complete development after all tasks

**Subagents should use:**
- **superpowers:test-driven-development** - Subagents follow TDD for each task

**Alternative workflow:**
- **superpowers:executing-plans** - Use for parallel session instead of same-session execution
