master 7b5bdcf4d3 feat(docs): Add comprehensive documentation for Vexer, Vulnerability Explorer, and Zastava modules 
- Introduced AGENTS.md, README.md, TASKS.md, and implementation_plan.md for Vexer, detailing mission, responsibilities, key components, and operational notes.
- Established similar documentation structure for Vulnerability Explorer and Zastava modules, including their respective workflows, integrations, and observability notes.
- Created risk scoring profiles documentation outlining the core workflow, factor model, governance, and deliverables.
- Ensured all modules adhere to the Aggregation-Only Contract and maintain determinism and provenance in outputs.

Implementation plan — Notify

Delivery phases

  • Phase 1 – Core rules engine & delivery ledger
    Implement rules/channels schema, event ingestion, rule evaluation, idempotent deliveries, and audit logging.
  • Phase 2 – Connectors & rendering
    Ship Slack/Teams/Email/Webhook connectors, template rendering, localization, throttling, retries, and secret referencing.
  • Phase 3 – Console & CLI authoring
    Provide UI/CLI for rule authoring, previews, channel health, delivery browsing, digests, and test sends.
  • Phase 4 – Governance & observability
    Add approvals, RBAC, tenant quotas, Notify metrics/logs/traces, dashboards, Notify-specific alerts, and Notify runbooks.
  • Phase 5 – Offline & compliance
    Produce Offline Kit bundles (rules/channels/deploy scripts), signed exports, retention policies, and auditing for regulated environments.

Work breakdown

  • Service & worker
    • REST API for rules/channels/delivery history, idempotency middleware, digest scheduler.
    • Worker pipelines for event intake, rule matching, template rendering, delivery execution, retries, and throttling.
    • Delivery ledger capturing payload metadata, response, retry state, DSSE signatures.
  • Connectors
    • Slack/Teams/Email/Webhook plug-ins with configuration validation, rate limiting, error classification.
    • Secrets referenced via Authority/Secret store; no plaintext storage.
  • Console & CLI
    • Console module for rules builder, condition editor, preview, test send, delivery insights, digests and schedule configuration.
    • CLI (stella notify rule|channel|delivery) for automation, export/import.
  • Integrations
    • Event sources: Concelier, Excititor, Policy Engine, Vuln Explorer, Export Center, Attestor, Zastava, Scheduler.
    • Notify events to Notify (meta) for failure escalations, accepted-risk expiration reminders.
  • Observability & ops
    • Metrics: delivery success/failure, retry counts, throttle hits, digest generation, channel health.
    • Logs/traces with tenant, rule ID, channel, correlation ID; dashboards and alerts.
    • Runbooks for misconfigured channels, throttling, event backlog, incident digest.
  • Docs & compliance
    • Update Notifications Studio guides, channel runbooks, security/RBAC docs, Offline Kit instructions.
    • Provide compliance checklist (audit logging, retention, opt-out).

Acceptance criteria

  • Rules evaluate deterministically per event; deliveries idempotent with audit trail and DSSE signatures.
  • Channel connectors support retries, rate limits, health checks, previews; secrets referenced securely.
  • Console/CLI support rule creation, testing, digests, delivery browsing, and export/import workflows.
  • Observability dashboards track delivery health; alerts fire for sustained failures or backlog; runbooks cover remediation.
  • Offline Kit bundle contains configs, rules, digests, and deployment scripts for air-gapped installs.
  • Notify respects tenancy and RBAC; governance (approvals, change log) enforced for high-impact rules.

Risks & mitigations

  • Notification storms: throttling, digests, dedupe windows, preview/test gating.
  • Secret compromise: secret references only, rotation workflows, audit logging.
  • Connector API changes: versioned adapter layer, nightly health checks, fallback channels.
  • Noise vs signal: simulation previews, metrics, rule scoring, recommended defaults.
  • Offline parity: export/import of rules, connectors, and digests with signed manifests.

Test strategy

  • Unit: rule evaluation, template rendering, connector clients, throttling, digests.
  • Integration: end-to-end events from core services, multi-channel routing, retries, audit logging.
  • Performance: burst throttling, digest creation, large rule sets.
  • Security: RBAC tests, tenant isolation, secret reference validation, DSSE signature verification.
  • Offline: export/import round-trips, Offline Kit deployment, manual delivery replay.

Definition of done

  • Notify service, workers, connectors, Console/CLI, observability, and Offline Kit assets shipped with documentation and runbooks.
  • Compliance checklist appended to docs; ./TASKS.md and ../../TASKS.md updated with progress.
