# issue-14-final-validation: Post-Build Verification and Complete AC Validation

## Description
Execute clean release build and verify all 17 acceptance criteria from the PRD (AC1-AC17). This read-only verification component validates binary size (≤500KB), confirms zero Python linkage, and produces a comprehensive validation report proving the repository is production-ready.

## Architecture Reference
Read `/Users/santoshkumarradha/Documents/agentfield/code/int-agentfield-examples/af-swe/example-pyrust/.artifacts/plan/architecture.md` Section "Component 14: Post-Build Verification & Final Validation" for:
- Complete validation script (Steps 1-4)
- Binary size verification commands (AC16)
- Python linkage verification commands (AC17)
- All 17 acceptance criteria checks (AC1-AC17)
- Error handling strategies for size/linkage failures

## Interface Contracts
- **Executes**: `cargo clean && cargo build --release`
- **Verifies**: Binary size via `stat -f%z target/release/pyrust` (macOS) or `stat -c%s` (Linux)
- **Verifies**: No Python linkage via `otool -L` (macOS) or `ldd` (Linux)
- **Output**: Validation summary report with PASS/FAIL for each AC

## Isolation Context
- **Available**: All code from completed issues 1-13 (already merged)
- **NOT available**: None (this is final validation)
- **Source of truth**: PRD acceptance criteria at `/Users/santoshkumarradha/Documents/agentfield/code/int-agentfield-examples/af-swe/example-pyrust/.artifacts/plan/prd.md` lines 54-86

## Files
- **Read-only**: `target/release/pyrust` (binary size check)
- **Read-only**: `Cargo.toml`, `.gitignore`, `README.md`, `LICENSE`, `docs/*.md`

## Dependencies
- issue-01 (PyO3 upgrade)
- issue-02 (compiler dead code)
- issue-03 (VM dead code)
- issue-04 (daemon_client closures)
- issue-05 (profiling cast warning)
- issue-06 (code formatting)
- issue-07 (file cleanup)
- issue-08 (gitignore enhancement)
- issue-09 (compiler len_zero)
- issue-10 (lexer/VM clippy)
- issue-11 (README creation)
- issue-12 (LICENSE creation)
- issue-13 (documentation consolidation)

## Provides
- Verified clean release build
- Binary size ≤500KB confirmation (AC16)
- Zero Python linkage confirmation (AC17)
- Complete validation of all 17 PRD acceptance criteria
- Production-ready repository state

## Acceptance Criteria
- [ ] `cargo clean && cargo build --release 2>&1` exits with code 0
- [ ] `stat -f%z target/release/pyrust 2>/dev/null | awk '{print ($1 <= 500000)}'` outputs `1` (binary ≤500KB)
- [ ] `otool -L target/release/pyrust 2>/dev/null | grep -c python` outputs `0` OR `ldd target/release/pyrust 2>/dev/null | grep -c python` outputs `0`
- [ ] `cargo clippy --lib --bins -- -D warnings 2>&1` exits with code 0
- [ ] All 17 PRD acceptance criteria (AC1-AC17) pass

## Testing Strategy

### Verification Script
- **Execute**: Architecture document Step 1-4 shell script
- **Validates**: Clean rebuild, binary size, linkage, all ACs

### Verification Categories
- **Build verification**: `cargo clean && cargo build --release` succeeds
- **Binary characteristics**: Size ≤500KB, no Python linkage (otool/ldd)
- **Code quality**: Zero warnings (AC1), zero clippy warnings (AC2), formatted (AC3)
- **File system**: Clean src/ (AC6), clean root (AC7), proper docs/ (AC12-AC13)
- **Production assets**: README ≥500 bytes (AC9), LICENSE exists (AC10), gitignore complete (AC11)

### Run Command
```bash
# Full validation
cargo clean
cargo build --release 2>&1

# Binary size (AC16)
stat -f%z target/release/pyrust 2>/dev/null | awk '{print ($1 <= 500000)}'

# Python linkage (AC17)
otool -L target/release/pyrust 2>/dev/null | grep -c python
```

## Verification Commands
- **Build**: `cargo clean && cargo build --release 2>&1 | tee /tmp/pyrust_build.log`
- **Size**: `stat -f%z target/release/pyrust 2>/dev/null | awk '{print ($1 <= 500000 ? "PASS" : "FAIL")}'`
- **Linkage**: `otool -L target/release/pyrust 2>/dev/null | grep python || echo "PASS (no Python linkage)"`
- **Summary**: Execute all AC1-AC17 verification commands and report results
