Why: Goal-sensitive workflow verification persisted model prompts and prior output text in trusted receipt rows, while cross-step model inputs could reuse stale machine output.
Evidence: RED receipt privacy test; full Go suite, targeted race, isolated PostgreSQL store/runmgr/storage-migrate tests, vet, and static build passed locally before commit. A known unrelated TempDir cleanup flake failed once and passed on targeted and serial full replay.
Impact: Add optional same-provider source recheck, verify every included item and evidence body before reuse, gate cross-step outputs, reject unsettled attempts, remove raw scope columns, scrub isolated candidate v34 SQLite/PG schemas, and reject unsafe backups.

Why: Project work currently reaches model calls without current authorized project facts or a persisted input receipt.
Evidence: SELF go test ./... -count=1, targeted go test -race for W6 paths, go vet ./..., and CGO_ENABLED=0 go build ./cmd/agent-system passed on this change set.
Impact: Add optional X1 interfaces, trusted persisted work-task binding, request-scoped context injection, evidence reauthorization, and attempted/responded/unknown manifests. Existing non-project behavior stays available.
