Continue the approved upstream catch-up after #608. User explicitly requested all five items, implementation in separate Pylon threads through Antigravity, and adversarial reviews before landing. Existing merge approval applies after review findings are resolved and final-head checks are green.
Frozen upstream head: 6d1d549441be84f19696ab59ed7e2fbf305280d4; cursor: bbedad0278bbf753503184c00e0c09a0eab6679c. Pylon base: 738b5ed9dc001ed49bbb6e9878e9291e1aa58479. 154 sources remain after #608; pending implementations do not reduce that count.
2db675aeffd9cb1e8b5ad76ddd018433b45b02e9 (#11485): provider account homes in usage tracking.
7931227977ca3e6f3354a63467caa634ab79796f (#11811): avoid refresh on every config subscription.
8b1ea4dd2465f3cf3cfa02d6878beaa1ec22e71a (#11741): Node discovery for WSL providers.
2a264adc6f6c65f98d4273acaa1af567eca83f2a (#11345): missing Codex executable diagnostics.
eed974c122e192de45b54b7dac7ca1a51448c08f (#11954): Claude rewind across fork history changes.
Five Antigravity implementation threads have isolated worktrees. Parent reviews combined changes and assigns separate adversarial reviews against completed commits. Keep Claude rewind separately reviewable from provider configuration/discovery. Preserve Pylon account isolation, admission, lifecycle, checkpoint/rollback ownership, remote auth, branding, and migration lineage. Focused regressions and affected package checks; CI owns the full suite. No release or device installation.
