feat(redact): semantic-pass eval + CLAUDE.md docs + size/parity baselines
- test/redact-semantic-pass.eval.ts: periodic-tier paid eval (EVALS=1) with 10 should-flag / should-clean fixtures + an injection-resistance case, the only way to detect semantic-pass model drift. - CLAUDE.md: "Redaction guard" section — engine/CLI/hook locations, the guardrail-not-enforcement framing, scan-at-sink, no-tier-promotion, the tool-attributed-fence convention, the config keys, and the audit log. - /cso uses the compact (HIGH-tier) taxonomy table so it fits under BOTH the v1.47 and the older v1.44.1 parity ceilings; full MEDIUM/LOW lives in lib/redact-patterns.ts. Alignment test asserts the HIGH-tier contract. - Refresh the ship golden baselines (claude/codex/factory) for the PR-body redaction wiring. Full free suite green (incl. skill-size-budget + parity 10/10). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
