Softcode CALL_FUNC is already total (guest error strings, never
ECALL_DECLINE). The residual poison was mid-run DBT failure (code buffer
full, harvest miss) returning false → full AST re-run after effects.
Track eval_ctx::host_ecalls on softcode host ECALLs; after entry, commit
#-1 JIT POST-ENTRY FAIL instead of re-running. Document the audit in
plan-softcode-post-entry-contract.md and cross-link the Lua plan.
