Molecule AI Backend Engineer f99d8b0a1a feat(platform): add per-workspace budget_limit field and A2A enforcement (#541) ... - Migration 025: ADD COLUMN budget_limit BIGINT DEFAULT NULL and monthly_spend BIGINT NOT NULL DEFAULT 0 to workspaces table - Models: BudgetLimit *int64 in CreateWorkspacePayload; MonthlySpend int64 in HeartbeatPayload - workspace.go: scanWorkspaceRow, workspaceListQuery, Get, Create, and Update all handle budget_limit/monthly_spend; budget_limit is gated as a sensitiveUpdateField - registry.go: heartbeat conditionally writes monthly_spend only when payload.MonthlySpend > 0 (avoids overwriting with zero) - a2a_proxy.go: checkWorkspaceBudget() returns 429 when monthly_spend >= budget_limit (NULL = no limit; fail-open on DB error) - Tests: 8 new workspace_budget_test.go tests + patched existing tests for the 20-column scanWorkspaceRow and 10-param CREATE INSERT Field type: BIGINT (int64), units: USD cents (budget_limit=500 = $5.00/month) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>		2026-04-17 06:18:41 +00:00
