- services/attest-reconciler/ as its own go.mod (admin-api internal/ is not importable; shared code gets extracted when a 3rd consumer appears).
- Scheduler accepts "@every <dur>" or a bare Go duration; context-cancellation stops the loop cleanly.
- Store client defines PendingRateStore + Postgres skeleton for SELECT ... WHERE rate_change_attestation_ref IS NULL.
- Orchestrator + HTTPSigner + tlog.HTTPSubmitter mirror admin-api byte-for-byte so the TLog idempotency key collides on resubmits (kein Doppelsignieren).
- Prometheus text-format /metrics endpoint, dependency-free: attest_reconciler_dirty_rows_total, _reconciliation_attempts_total, _reconciliation_failures_total, _idempotent_noop_total.
- Tests with fake store + fake signer + fake submitter cover: happy path, already-attested rows are NOT re-signed, TLog idempotency across ticks, TLog-down failure path, pre-cancelled ctx.
- Top-level README reflects the new service; CI auto-discovers services/*/go.mod so no workflow change needed.
