Decision

God-Grade Closure shipped: all 5 open recommendations from prior round closed in one cohesive session. (1) playwright-cli SKILL.md gained canonical reference-pattern section with 3 references; (2) r-dash nightly-smoke.yml GitHub Actions workflow shipped (03:00 IST cron + workflow_dispatch); (3) browser-use scope-narrowed to <1% rare-tier fallback excluding 24-platform known list; (4) WidgetCreate.exactly_one_source validator now allows chart_type=markdown without query/semantic anchor; (5) data-scientist installed as local skill at /root/.claude/skills/ with 17-phrase helix.default_for + Skill Mesh T3 registration (parents=[r-dash, autoresearch]). R-Dash committed b3822b8 + pushed to ARJ999/r-dash. Universal Completion Gate PASSED.

Rationale

All 4 Gate criteria verified: (1) Verification — skill-mesh-audit 0 ERROR, chrome-mcp guard regression-tests 3/3 pass, autoloader fires data-scientist + data-story-expert on data analysis prompt, registry rebuilt 164→165 skills, R-Dash 0/0 with origin after push. (2) /tmp clean of all session patterns. (3) Documentation cascade — 7 files updated atomically (4 SKILL.md, 1 registry.yaml, 1 schemas.py, 1 workflow.yml); MEMORY.md 173/200 with 96/96 links resolving. (4) Explicit Gate executed via this ST session. Pre-mortem identified 4 candidate failure modes — all mitigated by backward-compatibility (schema loosens not tightens), Not-tested trailer flagging (Actions secrets), graceful degradation (data-scientist references lazy population), and explicit escape valves (browser-use override path). Confidence 0.93 reflects evidence density. 0.93
