CODEX MASTER EXECUTION PLAN

Accounting Conservation Framework: Technical Remediation

Generated: 2025-11-04 Target Agent: Codex CLI Estimated Total Effort: 40-60 hours of focused coding Repository: /Users/nirvanchitnis/accounting-conservation-framework

OVERVIEW

This master plan contains 7 sequential directives to address critical issues identified in a technical review. The review flagged:

1. Credibility gaps: Metric inconsistencies between README and website
2. Reproducibility failures: No lockfile, no checksums, no artifact versioning
3. Compliance risks: Missing SEC EDGAR documentation, no SBOM, no security scanning
4. Test opacity: Unexplained test count discrepancies (292 defined vs 89 collected)
5. Validation limitations: 4.93% equity bridge pass rate (XBRL sparsity), 5% M&A detection TPR (heuristic limits)
6. Missing formal specs: Discrete RTT for consolidation lacks executable test oracles

Each directive is self-contained with: - Clear objective - Precise implementation steps - Definition of done (acceptance criteria) - Verification commands

EXECUTION ORDER

PHASE 1: QUICK WINS (Parallel Execution Possible)

These 4 directives fix critical credibility and infrastructure gaps. They are independent and can be executed in parallel or in any order.

Phase 1 Total: 13-18 hours Phase 1 Deliverable: Tag v0.1.0 with reproducible baseline

PHASE 2: ALGORITHMIC IMPROVEMENTS (Sequential Execution)

These 3 directives implement hard algorithmic enhancements. They may have dependencies on Phase 1 infrastructure (e.g., benchmarking uses reproducibility tools from CODEX_02).

Phase 2 Total: 28-35 hours Phase 2 Deliverable: Tag v0.2.0 with enhanced validation

DEPENDENCY GRAPH

PHASE 1 (Parallel):
├── CODEX_01 (Metrics Fix)          → Independent
├── CODEX_02 (Reproducibility)      → Independent (but used by Phase 2)
├── CODEX_03 (Compliance Docs)      → Independent
└── CODEX_04 (Test Transparency)    → Independent

       ↓ Tag v0.1.0 ↓

PHASE 2 (Sequential):
├── CODEX_05 (Equity Bridge)        → Requires CODEX_02 (for benchmarking/checksums)
├── CODEX_06 (M&A Detection)        → Requires CODEX_05 (uses XBRL parser enhancements)
└── CODEX_07 (Consolidation Oracles) → Requires CODEX_06 (uses boundary flux logic)

       ↓ Tag v0.2.0 ↓

Recommendation: Execute Phase 1 directives in parallel if Codex supports concurrent tasks. Otherwise, execute in numerical order (01 → 02 → 03 → 04).

DETAILED DIRECTIVE SUMMARIES

CODEX_01: Fix Metric Inconsistencies

File: CODEX_01_METRICS_FIX.md

Problem: - Website claims “72.3% equity bridge pass rate” but this is actually the LEVERAGE IDENTITY rate - Equity bridge is 4.93% (correctly stated in README, wrong in index.html) - Test count claims “240+ tests” without explaining 292 defined vs 89 collected

Solution: - Update 8 locations in index.html to distinguish leverage identity (72.3%) from equity bridge (4.93%) - Add test count explanation footnote to README - Update docs/EMPIRICAL_VALIDATION.html with methodology clarification

Key Changes: - index.html: 8 line edits (search/replace “72.3% equity bridge” → “72.3% leverage identity, 4.93% equity bridge”) - README.md: Add footnote explaining parametrized test expansion - docs/EMPIRICAL_VALIDATION.html: Add two-test methodology section

Definition of Done: - ✅ grep -n "72.3% equity bridge" index.html returns ZERO results - ✅ grep -n "72.3% leverage identity" index.html returns EIGHT results - ✅ README includes test count explanation - ✅ Deployed to GitHub Pages

Estimated Effort: 2-3 hours (mostly verification and deployment)

CODEX_02: Reproducibility Infrastructure

File: CODEX_02_REPRODUCIBILITY.md

Problem: - No poetry.lock (dependencies use open ranges like pandas>=2.1.0) - No checksums for result artifacts - No git commit hashes linking claims to code versions - Cannot guarantee exact replication

Solution: - Generate and commit poetry.lock - Pin security-critical packages (cryptography, httpx) - Enhance results/metadata.json with commit hash, timestamps, checksums - Create results/REPRODUCTION.md with step-by-step guide - Generate results/checksums.txt for all result files - Tag release v0.1.0

Key Changes: - poetry.lock: New file (~1500-2000 lines) - pyproject.toml: Pin security-critical deps with caret notation - results/metadata.json: Add version, commit_sha, dependencies_hash, dataset checksums - results/REPRODUCTION.md: New file with complete claim → script → artifact chain - results/checksums.txt: SHA256 hashes for all result files

Definition of Done: - ✅ poetry lock --check returns “consistent” - ✅ sha256sum -c results/checksums.txt all files OK - ✅ git tag includes v0.1.0 - ✅ README includes version and reproducibility badges

Estimated Effort: 4-6 hours (lockfile generation, metadata enhancement, documentation)

CODEX_03: Compliance & Security Documentation

File: CODEX_03_COMPLIANCE_DOCS.md

Problem: - No documentation of SEC EDGAR API compliance (rate limiting, User-Agent) - No SBOM (Software Bill of Materials) - No security scanning in CI (bandit, pip-audit)

Solution: - Create docs/compliance/SEC_EDGAR_COMPLIANCE.md documenting rate limiting (6.67 req/sec), User-Agent format, ToS compliance - Generate SBOM in CycloneDX JSON and XML formats - Add .github/workflows/security.yml with bandit (security linter) and pip-audit (vulnerability scanner) - Create docs/compliance/COMPLIANCE_CHECKLIST.md for enterprise/academic deployment

Key Changes: - docs/compliance/SEC_EDGAR_COMPLIANCE.md: New file (~200 lines) - SBOM.json and SBOM.xml: Generated artifacts (~500 KB each) - .github/workflows/security.yml: New CI workflow - pyproject.toml: Add bandit, pip-audit, cyclonedx-bom to dev dependencies

Definition of Done: - ✅ test -f docs/compliance/SEC_EDGAR_COMPLIANCE.md - ✅ jq '.components | length' SBOM.json returns >50 - ✅ poetry run bandit -r src/ completes (warnings OK, no ERRORS) - ✅ GitHub Actions security workflow runs successfully

Estimated Effort: 3-4 hours (documentation, SBOM generation, CI setup)

CODEX_04: Test Infrastructure Transparency

File: CODEX_04_TEST_TRANSPARENCY.md

Problem: - Test count claims (240+, 292 defined, 89 collected) unexplained - No test categorization or pass rate visibility - No property-based tests for core invariants (conservation, roll-forward)

Solution: - Add “Test Suite” section to README with collection explanation and test matrix table - Create property-based tests using Hypothesis (5+ tests for conservation invariants) - Generate coverage report (JSON + Markdown) - Update CI to upload coverage artifacts - Add coverage badge to README

Key Changes: - README.md: Add test suite section with matrix table and collection explanation - tests/property_based/test_conservation_invariants.py: New file (~200+ lines) - pyproject.toml: Add pytest markers configuration - coverage.json and coverage_report.md: Generated artifacts - .github/workflows/test.yml: Enhanced with coverage reporting

Definition of Done: - ✅ README includes test matrix table with pass rates by category - ✅ pytest tests/property_based/ -v passes all property-based tests - ✅ pytest --cov=src --cov-report=term shows >65% coverage - ✅ Coverage badge in README

Estimated Effort: 4-5 hours (test implementation, documentation, CI enhancement)

CODEX_05: Equity Bridge Enhancement (5% → 30%)

File: CODEX_05_EQUITY_BRIDGE_ENHANCEMENT.md

Problem: - Equity bridge pass rate: 4.93% (only 1 in 20 companies) - Root cause: XBRL tag sparsity for OCI components, dividends, buybacks in quarterly filings - Many companies report complete equity movements only in SOCE (Statement of Changes in Equity) or cash flow statement

Solution: - Phase 5A: Analyze XBRL tag coverage across 500 companies (which tags are most available?) - Phase 5B: Extend src/parsers/xbrl_api_client.py to fetch SOCE and cash flow data - Phase 5C: Create src/validation/equity_bridge_v2.py with SOCE → CFS → annual fallback logic - Phase 5D: Benchmark on full dataset, iterate until ≥25% pass rate achieved

Key Changes: - scripts/analyze_equity_bridge_coverage.py: New script analyzing tag availability - results/equity_bridge_tag_coverage.csv: Tag availability report - src/parsers/xbrl_api_client.py: Add fetch_equity_statement_components() method - src/validation/equity_bridge_v2.py: New validator with SOCE priority logic - tests/equity_bridge_v2/: Test fixtures for Microsoft, Apple, Lowe’s - docs/standards/EQUITY_BRIDGE_TAGS.md: Tag mapping documentation

Definition of Done: - ✅ Tag coverage analysis completed (CSV with 20+ tags) - ✅ Parser enhanced with SOCE/CFS fetching - ✅ Pass rate ≥25% (documented in results) - ✅ README updated: “4.93%” → “27% equity bridge (v2 with SOCE)”

Estimated Effort: 12-15 hours (tag analysis, parser enhancement, validator rewrite, benchmarking, iteration)

Strategic Notes: - This is the MOST IMPACTFUL algorithmic improvement (5x pass rate increase) - Requires XBRL expertise and careful mapping of IFRS/US GAAP tags - Iteration expected: Run benchmark on subset (50 companies), refine, then full dataset

CODEX_06: M&A Detection Improvements

File: CODEX_06_MA_DETECTION.md

Problem: - M&A detection: ~5% TPR (true positive rate) - misses 95% of events - Current approach: Basic heuristics (equity jumps) - High false positive risk: Stock splits, spin-offs look like M&A

Solution: - Phase 6A: Create labeled M&A event set (≥20 canonical deals: Boeing-Spirit, Microsoft-Activision, Disney-Fox, etc.) - Phase 6B: Implement 8-K Item 2.01 parser (SEC business combination disclosures) - Phase 6C: Build multi-signal detector with weighted scoring: - 8-K Item 2.01: 10x weight (highest confidence) - Goodwill discontinuity: 5x - Share count jump: 2x - NCI appearance: 3x - Boundary flux >$100M: 1x - Phase 6D: Calibrate threshold on labeled set to achieve ≥50% TPR at ≤10% FPR

Key Changes: - tests/ma_detection/labeled_events.csv: 20+ M&A events (manually curated + 8-K scraped) - tests/ma_detection/negative_events.csv: 10+ non-M&A events (splits, spin-offs) - src/parsers/edgar_8k_parser.py: New parser for SEC 8-K filings - src/validation/ma_detection_v2.py: Multi-signal detector with weighted scoring - scripts/run_ma_detection_benchmark.py: Benchmark script generating ROC curve - results/ma_detection_roc.png: ROC curve visualization - results/ma_detection_threshold.txt: Optimal threshold value

Definition of Done: - ✅ Labeled event set created (≥20 M&A, ≥10 negative events) - ✅ 8-K parser implemented and tested - ✅ TPR ≥50%, FPR ≤10% at optimal threshold - ✅ ROC curve generated (AUC ≥0.80) - ✅ README updated: “5% TPR” → “52% TPR at 9% FPR (v2 multi-signal)”

Estimated Effort: 10-12 hours (event set curation, 8-K parser, multi-signal logic, threshold calibration)

Strategic Notes: - Requires scraping SEC EDGAR for 8-K filings (respect rate limits) - Labeled event set is CRITICAL - quality of ground truth determines success - Include negative events to measure FPR (avoid false positives on splits/spin-offs)

CODEX_07: Consolidation Test Oracles (IFRS 10)

File: CODEX_07_CONSOLIDATION_ORACLES.md

Problem: - Discrete RTT (Reynolds Transport Theorem) for M&A is mathematically defined but lacks executable tests - No formal specification for how boundary flux (perimeter changes) decomposes from operational changes - IFRS 10 consolidation logic documented but not validated with synthetic test cases

Solution: - Phase 7A: Define YAML schema for consolidation oracles (pre/post state, discrete RTT decomposition) - Phase 7B: Create ≥10 oracle fixtures covering IFRS 10 scenarios: - Acquire subsidiary (100%, 80% with NCI, with goodwill) - Deconsolidation (loss of control) - Step-up NCI (increase ownership from 80% → 100%) - Partial disposal (retain control) - Edge cases: negative equity subsidiary, FX translation, goodwill impairment, spin-off - Phase 7C: Implement src/validation/consolidation_oracle.py to validate discrete RTT decomposition - Phase 7D: Document oracles with IFRS 10 paragraph mapping

Key Changes: - tests/consolidation/oracles/schema.md: Oracle fixture format documentation - tests/consolidation/oracles/oracle_01_*.yaml through oracle_10_*.yaml: 10+ fixtures - src/validation/consolidation_oracle.py: Validator checking Δequity = operational + boundary_flux - docs/proofs/CONSOLIDATION_ORACLES.md: Documentation with IFRS 10 mapping table

Definition of Done: - ✅ ≥10 oracle fixtures created - ✅ Each fixture includes IFRS 10 paragraph citation, pre/post state, discrete RTT explanation - ✅ pytest tests/consolidation/oracles/ -v all oracles PASS - ✅ Documentation created with usage guide

Estimated Effort: 6-8 hours (schema design, fixture creation, validator implementation, documentation)

Strategic Notes: - This is the MOST CONCEPTUALLY RIGOROUS work (formal specification of boundary flux) - Each fixture is a “unit test” for the discrete RTT theorem - Provides defensible foundation for M&A detection improvements (CODEX_06)

NOTES FOR CODEX

1. Each directive is self-contained. You do not need to read all 7 directives upfront. Read directive 01, execute, verify, then move to 02.

2. Verification commands are mandatory. Run ALL verification commands in the “VERIFICATION COMMANDS” section of each directive before marking as complete.

3. Commit messages are provided. Use the exact commit message format shown in each directive.

4. Ask questions if stuck. If a directive step is unclear or a verification fails, ask the user for clarification rather than guessing.

5. Strategic flexibility in Phase 2. Directives 05-07 include “strategic notes” indicating where you should explore/iterate rather than blindly following exact steps. For example:

   • CODEX_05: Analyze tag coverage FIRST, then decide which tags to prioritize
   • CODEX_06: Calibrate threshold iteratively until TPR/FPR targets met
   • CODEX_07: Write fixtures one at a time, test each before moving to next

6. Time estimates are conservative. You may complete faster if you parallelize sub-tasks within a directive.

7. Git hygiene: Commit frequently (after each sub-phase), with clear messages. Do NOT batch all changes into one giant commit.

8. Deploy early, deploy often. After each directive that modifies README or index.html, deploy to GitHub Pages and verify live site.

EMERGENCY STOP CONDITIONS

Stop execution and ask user if: 1. Any verification command FAILS repeatedly (>2 attempts) 2. A directive assumption is violated (e.g., “Expected file X to exist” but it doesn’t) 3. Pass rate targets cannot be met even after iteration (e.g., equity bridge stuck at 10% despite trying multiple fallback strategies) 4. Time spent on a single directive exceeds 2x the estimated effort (indicates blocked or misunderstood requirement)

Minor issues that do NOT require stop: - Mypy type errors (mypy is disabled in pre-commit) - Bandit warnings (only ERRORS block) - Coverage <100% (target is >65%, not perfection) - Minor FPR drift (e.g., 11% instead of 10% is acceptable if TPR target met)

FINAL CHECKLIST (After All 7 Directives)

• All verification commands pass
• Git tags v0.1.0 and v0.2.0 pushed to GitHub
• GitHub Actions CI passes (tests, lint, security)
• README metrics updated and consistent with website
• GitHub Pages deployed with latest changes
• CODEX_COMPLETION_REPORT.md committed

When complete, reply:
