Native exception-language tradeoffs page (docs/native-language-tradeoffs.md): evidence-backed biggest-risk table for Zig, Rust, Nim, Odin, and Mojo, with a rebuttal rule for justification item 5. Linked from exception-to-go (wrong-answer paragraph, item 5, Related) and the site manifest.
Lifetime/leak gate for Zig kernels (docs/exception-to-go.md): alloc-adjacent defer/errdefer, DebugAllocator/testing.allocator leak checks, forced error paths, ~10k-call loop test; mirrored as a checklist in the coding-standards skill.
Stack tradeoff depth (docs/stack-layers.md): Go vs TypeScript/Python (flywheel, two-interpreter GIL, npm install-hook supply chain, stdlib breadth, race detector, cold start); PocketBase vs Postgres graduation rule, SQLite/WAL scale numbers, PB scaling ladder, stdlib-router note (Gin/Echo/Chi); React/Next flywheel costs vs Datastar + datastar-lint.
"Not a framework" stated plainly: landing hero, README intro, and a docs/overview.md section — template hands you the code and leaves.
Motivation thesis sharpened: title names Zig as the exception; new paragraph tying each Go motive to its criterion.
