Decision

DSR pipeline reschedule blocked by session-cache staleness (NOT server gap); resolution = fresh Claude session inherits v19.1.2/v6.0.4 tool surfaces and executes autonomously

Rationale

Both MCP servers verified live with new tools via direct curl on /health + /mcp tools/list. This session’s deferred-tool registry was populated before container restart and holds pre-upgrade schemas. Class-shift from “missing-server-feature” (prior 25-Apr docs) to “session-transport-cache miss” matters because the remediation path differs entirely (operator restart vs dev MCP patch). One harmless validated probe (nested daily_sync_time inside config) confirmed connector state unchanged. Fresh session is the cleanest fix. fivetran, tableau, mcp-upgrade, st-derived, reversible, standard

Alternatives Rejected

Outcome

Pending
