The runtime contract gated on total consultation tool attempts, so a single
transient calculation failure raised the counter past one and made the run
unrecoverable even after a later attempt succeeded. The already-computed chart
was discarded and the request ended as runtime_contract_incomplete.
Count only successful workflow executions against the single-calculation
boundary. Failed attempts stay in the attempt counter for observability. The
request-scoped cache still retains the successful promise, so a request can
never run more than one billable calculation.
Also record the staging-first branch delivery convention in AGENTS.md.
