Decision
Install chrome-devtools-mcp as Permanent 9 with cascade across 16 canonical setup files + stitch into 4 perf-related skills as PRIMARY engine. Decision substantively holds per 3-gate ceiling-expansion rule despite anchoring bias surfaced in metacog audit.
Rationale
Ceiling-expansion rule satisfied: (a) explicit AJ authorization, (b) uncovered gap — Lighthouse-on-demand + CrUX field data + memory snapshots + source-mapped stacks not covered by any existing Permanent or Desktop Connector or skill+CLI shell-out, (c) cascade executed same operation. Metacog audit (detect_biases + premortem + draw_conclusion in ST session 45e94c19) flagged anchoring bias on the decline-to-install flip but confirmed substantive 3-gate test still passes. Confidence calibrated at 0.78 reflecting bias finding and 3 follow-ups logged: skill-side public-vs-gated URL guard, 6-month review checkpoint 2026-11-16 in evolution-backlog, real lighthouse_audit smoke test on next session before relying on the 4-skill stitching.
