Close the missing feedback loop. Detection (v_scraper_health, v_data_quality_alerts,
check_switch_quality) was accurate but inert; dispatch was blind fixed-cadence
(boss.send() is never called from any health path). tip-dqo is a separate, read-mostly
control plane that closes DETECT -> PRIORITIZE -> DISPATCH -> VERIFY -> RECHECK against
observation-table freshness (never pg-boss job state), with DB-enforced guardrails.
- sql/129: source_registry (signal->queue map + per-source SLA + guardrail contract +
global kill-switch), self_heal_dispatch append-only ledger, scraper_run_log,
acknowledged_exceptions, v_dqo_targets ranked view.
- orchestrator/: control-loop, self-heal-guards (pure, unit-tested), escalation-sink
(ntfy + no-op fallback), index entrypoint. Reuses the verification-robots dispatch
idiom (extracted shared dispatchQueues) and the quality views as-is.
- Guardrails: kill-switch, plan-mode default, per-source cooldown/budget/backoff/
circuit-breaker, load-guard, erik-safe profile cap, delta-gated escalation. Root-cause
routing escalates code_fix/blocked (e.g. ATGBICS silent stock-write break) to a human
instead of looping retries; only staleness is auto-dispatched.
- security: remove hardcoded 'tip_dev_2026' DB password fallback across 6 sites ->
fail-closed requireDbPassword() / dbConnectionString().
SELF_HEAL_PLAN_ONLY defaults true (dispatches nothing; writes plan rows for review).
Verified against the live DB: detects ATGBICS-stock dead/54d -> escalate, Flexoptix-stock
stale/30d -> plan-dispatch; guards + ledger correct; 8/8 guard unit tests pass.
