Why: The E1 quick-fix increment landed (delegate full text, MiniMax
reasoning split, sandbox deps layer, parallel tool execution with kernel
ordering) and the proposal is the master record, so its stage table and
the index row must reflect the actual progress with links.
Evidence: Agent-Native #42/#43/#44, Backend #127, Dev task
feature/agent-e1-parallel-fixes (live verification receipts: F2 zero
think-leak, F3 sandbox IMPORTS-OK, F5 concurrent overlap; eval
toolFailures 19->11, unverifiedFacts 7->12 recorded honestly).
Impact: Documents-only progress backfill; E2-E5/S0 remain unauthorized.
