Model-switch re-review found 7 real defects, fixed before any code:
- fail-open contract now covers unexpected errors (403/5xx/DNS/timeout)
via top-level try/except -> degraded JSON, exit 0 (was: traceback+exit 1)
- test isolation: SEO_DATA_ENV_FILE override so tests never source the
real vault (degrade tests would hit network on machines with live keys)
- CrUX: None-safe normalizer (missing INP on low-traffic sites) +
origin-level fallback on page-level 404
- refresh errors split token_revoked (RefreshError) vs network_error
- fixed set-u STORE_MISSING ordering bug in Task 4 test
- Makefile read -p bashism wrapped in bash -c (dash-safe)
- SKILL.md fetch path -> ~/.claude/lib/... (skills run from project dir)
- spec/plan aligned: label not email in accounts output, ok+[] not
'empty', CrUX history -> YAGNI v2, PageSpeed-key routing rejected v1
(key would enter subagent context)
