v1.1.1 — Production-Hardening (Council v1.1+corpus fix)

v1.1.1 — Production-Hardening Release

Closes 3 CRIT + 5 HIGH findings from the v1.1+corpus adversarial council.

Score: 62/100 → 92/100 (honest prod-readiness)

CRIT (3 closed)

• CRIT-1: pyproject.toml build backend — was setuptools.backends._legacy:_Backend (doesn't exist). Fixed to setuptools.build_meta. python -m build now works.
• CRIT-2: state.db plaintext by default — EncryptedStateDB is now the default. Opt-out via --no-encrypt.
• CRIT-3: 6 corpus modules were dead code — Now wired into cmd_measure (failure_detector), cmd_spawn (token_economics), cmd_view (progressive_disclosure), and exported from lib/__init__.py.

HIGH (5 closed)

• HIGH-1: security_fallback.py coverage 19% → 100% (+11 tests)
• HIGH-2: IsolatedExecutor 0% → ~100% (+8 tests)
• HIGH-3: cli.py 30% → ~80% (+15 tests)
• HIGH-4: token_ledger.py 59% → 95% (+10 tests)
• HIGH-5: llm_view.py 71% → 95% (+9 tests)

Stats

• Tests: 425 → 478 (+53)
• Coverage: 85.77% → 88%
• Commits since v1.1.0: 1 (f1a41ed)

Known follow-ups (deferred)

• MED-1: Node.js 20 deprecation on GH Actions (2026-06-16)
• MED-2/3/4: image_pin, ci_cd_pinning, mcp_trust coverage gaps (cosmetic)

v1.1.0 — Production-Ready

CE-Harness v1.1.0 — Production-Ready

All findings from the integral analysis council (40/100) resolved with real code.

Security (CISO 18→80+)

• EncryptedStateDB — AES-256-GCM encryption at rest for state.db (opt-in CTXH_ENCRYPTED=1)
• PII salt persistence — deterministic tokens across process restarts
• SIGTERM handler — graceful shutdown with WAL checkpoint
• Replaced os.popen('date') with datetime.now().isoformat()

Architecture (Architect 38→80+)

• L4 LLM View Builder — head/middle/tail layout (lost-in-the-middle mitigation)
• Subprocess isolation — IsolatedExecutor via multiprocessing.Process
• New CLI command: ctxh view <phase>

Observability (DevOps 42→80+)

• Structured JSON logging — CTXH_LOG_LEVEL / CTXH_LOG_FORMAT
• Health check — ctxh health [--json] for monitoring integration
• pyproject.toml — pip install ce-harness
• CI release workflow — auto GitHub release on tag

Stats

• 355/355 tests pass (Python 3.10-3.13, 4/4 CI matrix green)
• 79% coverage (78% gate enforced)
• 10.8× token economy verified end-to-end
• +1833 LOC across 17 files

Installation

pip install ce-harness[crypto]
# or from source:
git clone https://github.com/doz34/context-engineering-harness

CE-Harness v1.0.3 — Fresh-eyes audit fixes (1 CRIT + 5 HIGH + 2 MED)

CE-Harness v1.0.3 — Fresh-eyes audit fixes

🎯 Highlights

• 324/324 tests pass (was 318, +6 new for the fixes)
• 1 CRIT + 5 HIGH + 2 MED closed from audit/fresh-eyes-v102/ (full 7.5h audit)
• Score : 62.65/100 → ~80/100 post-fixes
• Dogfooding : project's own CI now runs ci_cd_pinning.validate_workflow_file on itself

🔒 Security fixes

ID	Severity	What	Where
F-001	🔴 CRIT	Project's own CI used mutable tags @v4/@v5 while the lib is designed to reject them. Now SHA-pinned + self-audit step.	.github/workflows/tests.yml
F-002	🟠 HIGH	security_fallback.py docstring claimed AES-256-CTR but the impl is SHA256-CTR (stdlib has no AES). Docstring fixed.	lib/security_fallback.py
F-003	🟠 HIGH	state.record_token accepted negative ints, allowing budget bypass via record_token(-999999). Now raises ValueError.	lib/state.py
F-004	🟠 HIGH	StateDB.verify_audit_chain() didn't exist — HMAC chain was append-only, not verifiable. New method walks the chain.	lib/state.py
F-006	🟠 HIGH	hooks.post_tool_use_clear_result sanitized tool_name but NOT ctx.timestamp — path traversal via ../../etc/cron.daily/.... Now both hardened.	lib/hooks.py

⚙️ Quality fixes (bonus MED)

• F-008 : post_tool_use_pii_tokenize now uses singleton tokenizer (deterministic tokens across calls)
• F-011 : append_audit except narrowed + logs the fallback (was swallowing all errors silently)

📊 What the audit covered

• 12 quality dimensions (HumanLayer 2026, OWASP LLM Top 10, CWE Top 25, STRIDE)
• 7 angles + corpus review
• 4 simulated reviewers (ciso/qa/architect/devops) + 1 real Explore agent
• 1.0.2 fresh-eyes (this audit) found 26 findings (1 CRIT, 5 HIGH, 7 MED, 13 LOW)
• 23 modules, ~5,200 LOC

📝 Migration from v1.0.2

No breaking changes. Just git pull and pip install -e . (or no-op if not installed).

git pull origin main
cd prototype
python3 -m pytest tests/ -v  # 324/324 PASS
bash bin/install.sh          # ✅
bash bin/ctxh-demo           # ✅

🔮 Next

v1.0.4 backlog : F-007 (PII checksums), F-009 (install.sh stdlib), F-013 (semver pinning), F-020-F-026 (P3 debt). See audit/fresh-eyes-v102/06-prioritized-actions.md.

CE-Harness v1.0.2 — Quality Sprint

CE-Harness v1.0.2 — Quality Sprint

14 latent bugs fixed in one substantive patch, organized into 4 batches. Each fix is user-facing: it repairs something that would break the demo, the install, or the CLI for an end user. No new modules, no new dependencies.

What's fixed

Batch A — 4 bugs user-blocking (install/demo)

• ci_cd_pinning.validate_workflow_file — try/except around import yaml; returns clear PinningResult ERROR instead of crashing the CLI when pyyaml is missing
• security.py — pre-import AESGCM and security_fallback at module top-level so the fallback path is never broken by relative-import failures (e.g., script mode)
• code_api.SAFE_BUILTINS — adds __build_class__ and exception types (ZeroDivisionError, ValueError, etc.) so legitimate class and try/except blocks work
• contract_validator.load_and_validate — fixed broken YAML→JSON fallback; now returns a clear ContractResult error

Batch B — 3 functional bugs

• validate_github_workflow — handles container as a string and services as a list (both legal GitHub Actions forms that were silently accepted)
• safe_subagent_result — rejects oversized values via ValueError instead of silently truncating (99999999999999 → 9999999999 was corrupting token counts)
• post_tool_use_clear_result — sanitizes tool_name via regex (defeats ../../../../tmp/evil path traversal)

Batch C — 4 correctness bugs

• PBKDF2 epoch key derivation iterations 1,000 → 200,000 (OWASP 2023 floor)
• state.append_audit — read prev_hash and INSERT now share a single BEGIN IMMEDIATE transaction (TOCTOU race fixed)
• pii_tokenizer.detect — pre-processing pass (NFKC + URL-decode + HTML-unescape) defeats alice%40acme.com, alice＆#64;acme.com, alice＠acme.com (fullwidth) bypasses
• code_api.execute — wall-clock timeout parameter (default 30s) via SIGALRM; while True: pass no longer hangs the agent

Batch D — 3 claim/code alignment

• RotatingHMAC.verify(strict_epoch=True) — actually enforced now (the docstring promised this; the code was a no-op)
• verify_isolation — inspects the ledger DB for real instead of returning a hardcoded dict; returns is_valid=False with reason if the subagent was never spawned
• memory_blocks — PRAGMA foreign_keys=ON on every connection (was declared but not enforced)

Tests

• 318/318 pass (one new test added for strict_epoch invariant)
• Adversarial suite unchanged (green)
• Install + demo: green
• pip uninstall cryptography pyyaml → 317/318 (1 skip on the yaml test, expected)
