+## [0.7.1] — 2026-03-12
+
+### Fixed — Self-Validation Findings (PR #14)
+
+Ran Quorum self-validation (standard depth) against all shipped artifacts in v0.6.1, Copilot CLI Port, Golden Test Set, and core engine. Fixed **64 findings** across **10 files** — 3 CRITICAL, 16 HIGH, 45 MEDIUM/LOW.
+
+#### Critical Fixes
+- **aggregator.py** — INFO-only findings now correctly produce PASS (not PASS_WITH_NOTES), honoring the documented verdict contract
+- **pipeline.py** — `resume_batch_validation` now restores original config + relationships_path from manifest (was hardcoding None, causing resumed batches to produce different results than original runs)
+- **models.py** — `Locus` now validates `start_line <= end_line` and `_hash_byte_range` raises ValueError on out-of-bounds ranges instead of silently hashing empty bytes
+
+#### High-Impact Fixes
+- **Severity normalization** (base.py, cross_consistency.py) — malformed LLM severity strings no longer discard ALL findings for that critic
+- **Format-string injection** (cross_consistency.py) — user YAML `scope` field now brace-escaped before `str.format()`
+- **Deterministic dedup** (aggregator.py) — findings sorted by severity before greedy matching; output no longer depends on input ordering
+- **CancelledError handling** (pipeline.py) — cancelled futures in batch loops no longer crash pipeline
+- **Library-safe prescreen** (quorum-prescreen.py) — `run_prescreen()` returns error dicts instead of calling `sys.exit()`
+
+#### Tests
+- 879 passed, 0 failures
+- 2 tests updated: `test_info_finding_pass_with_notes` and `test_verdict_json_serialization_never_none` (codified buggy behavior; now corrected)
+
+#### Process
+- Added mandatory self-validation step to Claude Code task template (`~/.claude/tasks/README.md`)

+# Quorum — Claude Code Skill
+
+Multi-critic quality validation for code, configs, and documentation.
+
+## Install
+
+```bash
+git clone https://github.com/SharedIntellect/quorum
+cp -r quorum/ports/claude-code ~/.claude/skills/quorum
+```
+
+## Usage
+
+### Full validation (all critics)
+"Run Quorum validation on this file"
+"Validate api_handler.py with Quorum"
+
+### Single critic
+"Run the security critic on auth.py"
+"Check this config for completeness"
+
+### Cross-artifact consistency
+"Check if implementation.py matches spec.md"
+
+## What It Checks
+- **Correctness** — Logic errors, contradictions, false claims
+- **Completeness** — Missing sections, edge cases, broken promises
+- **Security** — OWASP ASVS 5.0, CWE Top 25, framework-grounded
+- **Code Hygiene** — ISO 25010/5055, structural quality beyond linting
+- **Cross-Consistency** — Spec/impl, docs/code, schema contracts
+
+## Verdict Scale
+- **PASS** — No issues found
+- **PASS_WITH_NOTES** — Minor issues only (MEDIUM/LOW)
+- **REVISE** — HIGH severity issues requiring rework
+- **REJECT** — CRITICAL issues found
+
+## Requirements
+- Claude Code CLI
+- Python 3.10+ (for pre-screen script)
+- No additional dependencies
