Security Validation Record

Historical validation date: 2026-07-23 (local project date). Counts and scanner results below describe that run, not a new security certification.

Baseline

The repository SECURITY.md entry recorded 10 findings with maximum severity CRITICAL:

• Cross-file environment-variable and network exfiltration
• A multi-file collection/transmission chain
• Environment harvesting in both schematic scripts
• API-key transmission to an external model service
• Full environment propagation to a subprocess
• Repeated costly model/image operations
• Mandatory external schematic/cross-skill behavior

The affected files were:

• Deleted: scripts/generate_schematic.py
• Deleted: scripts/generate_schematic_ai.py
• The former SKILL.md

Remediation

• Deleted both external schematic scripts.
• Removed credentials, environment access, .env loading, subprocess chaining, network requests, model calls, image generation, mandatory figures, and cross-skill calls.
• Replaced them with bounded deterministic local JSON/CSV/Markdown validators and generators.
• Added strict schemas, duplicate-key/header detection, size/row/cell limits, symlink rejection, private atomic output, and no implicit overwrite.
• Added report minimization: IDs, counts, rule codes, and line numbers instead of manuscript/review prose.
• Added AST tests that reject network libraries, executable serialization, dynamic code execution, and environment credential access.
• Added confidentiality, no-reuse, authorization, conflict, competence, AI-policy, disclosure, and deletion/retention gates.

Validation results

• Agent Skills reference validator: PASS
• Dependency-free CLI help checks: PASS
• Synthetic standard-library tests: 26 passed
• Explicit AST parse with bytecode disabled: 8 scripts parsed
• Bytecode artifacts: 0
• IDE lints: 0
• Documented local-path link test: PASS
• Markdown link check: PASS (access-controlled HTTP 403 treated as reachable)
• Direct behavioral security scan: SAFE, 0 findings
• Pull-request gate with --fail-on HIGH: PASS
• CRITICAL: 0
• HIGH: 0
• LOW: 3

Residual LOW findings

The final LLM-assisted pull-request scan reported:

1. **Missing allowed-tools declaration** — informational. This field is optional under the Agent Skills specification. The compatibility and body explicitly constrain bundled tools to local standard-library processing with no network, model, image, credential, or environment access.
2. Broad description — accepted as a scoped capability description. The mandatory authorization and venue-policy gate applies before confidential content is read, and the body limits all functions to peer-review assessment.
3. Bounded CSV/JSON processing — defensive observation with “no action required” in the scanner output. Inputs are already limited to 4 MiB, 5,000 CSV rows, 12,000 characters per cell, and finite list sizes; tests cover oversize rejection.

None of the LOW findings permits data transmission or credential access. No CRITICAL or HIGH issue remains.

The repository-level SECURITY.md was intentionally not edited in this scoped refresh; its generated snapshot will update through the repository’s normal scan process.

2026-10-01 maintenance checks

The intake now distinguishes a disclosed conflict awaiting clearance from actual editor clearance. The reporting catalog adds SPIRIT-AI protocols and non-prediction LLM studies. Standard-library synthetic tests pass (30 tests and 7 CLI-help subtests), and skills-ref validate passes. A new collection-level security scan is coordinated separately; the historical scanner counts above were not rerun for this record. These checks use synthetic inputs and do not constitute a live manuscript review.
