Problem: The PR made provider-visible schemas conditional on Goal, Plan, and Jobs context, removing update_goal from ordinary and economy requests and violating the required byte-stable tool contract.
Root cause: A broad contextual-tool mechanism was added while hardening Goal recorder isolation, coupling an execution boundary to provider schema selection.
Fix: Restore static Schemas() requests and the main-v2 tool order, remove contextual schema APIs and phase-specific visibility, and keep only execution-time Goal recorder isolation for planners and child agents. Correct the changelog and cache-impact coverage.
Verification: go test ./internal/agent ./internal/boot ./internal/control ./internal/tool ./internal/tool/builtin -count=1; go run ./tools/repolint; git diff --exit-code origin/main-v2 -- internal/agent/extensions.go internal/agent/run_loop.go internal/agent/sampling_request.go internal/tool/tool.go internal/tool/builtin/bgjobs.go internal/tool/builtin/completestep.go internal/tool/builtin/updategoal.go internal/jobs/jobs.go internal/memory/queue.go; git diff --check
