description	Diagnose and fix build failures systematically
disable-model-invocation	true

A build failure needs debugging. Context: $ARGUMENTS

Steps

1. Run tools/ai/check_digest.sh nix develop --command cargo check --all-targets to get current errors
2. Categorize errors:
   • Type errors: mismatched types, missing trait impls
   • Import errors: unresolved imports, missing modules
   • Lifetime errors: borrow checker issues
   • Proto errors: generated code mismatch (may need cargo build -p lifelog-proto first)
3. Fix errors starting from the dependency root (errors in common/ before server/, proto before everything)
4. After each fix, re-run check_digest to verify progress
5. Once clean, run just validate to ensure clippy + tests also pass

IMPORTANT: If proto-generated code is stale, rebuild proto first: nix develop --command cargo build -p lifelog-proto
