Audit Phase 4 (Script Generation, SCR-01..05) against Nyquist rules. Upgrade `04-VALIDATION.md` in place. Pay special attention to SYSTEM-context claims (pnputil, $PSScriptRoot) — per STATE.md these are attestation-only PASSes from Phase 10 and the audit must reflect that weakened audit trail in the Notes column.

Purpose: Fourth of 7 per-phase audits feeding the milestone index. Output: Upgraded .planning/phases/04-script-generation/04-VALIDATION.md.

Extract Phase 4 (SCR-01..05) success criteria from `.planning/milestones/v1.0-ROADMAP.md`. 2. One observable check per criterion; evidence in priority order. 3. Preserve all existing sections; append `## Nyquist Record`. 4. For any criterion that requires runtime SYSTEM-context proof (pnputil staging, $PSScriptRoot resolution, detect/uninstall under SYSTEM): evidence is the Phase 10 RUNTIME-VALIDATION.md report. **Mark Notes explicitly that RTVAL-02/03/04 are attestation-only PASSes per STATE.md** — the audit records this weakened audit trail faithfully, it does not hide it. Status may still be `pass` since Phase 10 signed off with explicit acknowledgement, but Notes must say "attestation-only per STATE.md 2026-04-13". 5. Update frontmatter. grep -q "^## Nyquist Record" .planning/phases/04-script-generation/04-VALIDATION.md && grep -q "nyquist_audited:" .planning/phases/04-script-generation/04-VALIDATION.md 04-VALIDATION.md has a complete Nyquist Record, SYSTEM-context rows cite Phase 10 with the attestation-only caveat in Notes, and frontmatter is updated. - `## Nyquist Record` section exists in 04-VALIDATION.md - Row count matches Phase 4 success criteria - Any row citing SYSTEM-context / pnputil / $PSScriptRoot has the "attestation-only" note - Frontmatter has nyquist_audited + nyquist_auditor keys

<success_criteria> Phase 4 Nyquist audit complete with honest recording of the attestation-only runtime evidence. </success_criteria>
