+ * This package defines stable domain abstractions related to long-running + * PKI workflows and their durability requirements. It is concerned with + * describing what must be persisted and how durable such persistence + * must be, not with how the persistence is implemented. + *

+ * + *

Scope and responsibilities

+ *

+ * The orchestration layer in ZeroEcho PKI coordinates multi-step operations + * such as certificate issuance, revocation processing, key rollover, or + * publication workflows. These operations: + *

+ *
    + *
  • may span multiple logical steps,
    • + *
  • may involve external systems or asynchronous callbacks,
    • + *
  • must tolerate restarts, crashes, or redeployments.
    • + *
+ * + *

+ * This package provides the minimal API necessary to: + *

+ *
    + *
  • describe the required durability guarantees for workflow state,
    • + *
  • represent persisted workflow state in a storage-agnostic form,
    • + *
  • enable deterministic recovery and audit of workflow progression.
    • + *
+ * + *

Key abstractions

+ *
    + *
  • {@link zeroecho.pki.api.orch.OrchestrationDurabilityPolicy + * OrchestrationDurabilityPolicy} defines how durable orchestration + * state must be (e.g. write-through, buffered, best-effort), allowing different + * operational trade-offs without changing orchestration logic.
    • + *
  • {@link zeroecho.pki.api.orch.WorkflowStateRecord WorkflowStateRecord} + * represents an immutable, persisted snapshot of workflow state at a specific + * point in time, suitable for recovery, audit, and historical inspection.
    • + *
+ * + *

Immutability and history

+ *

+ * Workflow state records are designed to be immutable once persisted. + * Implementations are expected to append new state records rather than + * overwrite existing ones, enabling: + *

+ *
    + *
  • full audit trails,
    • + *
  • temporal queries ("state at time T"),
    • + *
  • post-mortem analysis of failed or aborted workflows.
    • + *
+ * + *

+ * Whether and for how long historical records are retained is governed by + * policy and implementation, but the API itself is intentionally compatible + * with history-preserving stores. + *

API stability and integration

+ *
    + *
  • standalone CLI applications,
    • + *
  • long-running server processes,
    • + *
  • container-managed frameworks such as Spring or Micronaut.
    • + *
+ * + *

+ * No assumptions are made about the underlying persistence mechanism + * (filesystem, database, distributed log, etc.). Such concerns are handled by + * SPI and implementation layers. + *

*
    - *
  • Deterministic serialization across JVM runs.
    • - *
  • No external dependencies.
    • - *
  • Support for records (the dominant pattern in the PKI API).
    • + *
  • Compact format (current): begins with a 1-byte MAGIC marker + * {@code 0xFF}, followed by a 1-byte TAG and tag-specific payload.
    • + *
  • Legacy format (backward-compatible): begins with a UTF-8 encoded + * Java class name (written by + * {@link zeroecho.core.io.Util#writeUTF8(OutputStream, String)}), followed by + * value payload based on that class.
    • *

  • Java {@code record} types, recursively

    + * This package provides a reusable, strongly-typed abstraction for submitting + * asynchronous operations, tracking their status, and delivering status changes + * to registered callback handlers. It is intentionally generic: concrete + * subsystems (e.g., PKI issuance, publishing, signing workflows) instantiate + * the bus by selecting: + *

    + * + *
      + *
    • operation identifier type (e.g., {@code PkiId}),
      • + *
    • operation owner type (e.g., {@code Principal}),
      • + *
    • endpoint identifier type (e.g., {@code String}),

    • result type (application-specific, may be empty).

    + * + *

    Durability model

    + *

    + * The default reference implementation is append-only: it persists operation + * snapshots and status transitions to a file log. On startup it replays the log + * and then optionally re-synchronizes open operations by asking the endpoint + * for their current status. + *

    + * + *

    Security

    + *
      + *

    + * This package contains small, focused utility components that support the PKI + * domain model and its surrounding infrastructure without introducing + * additional domain semantics. Utilities provided here are intended to be: + *

    + *
      + *
    • deterministic and side-effect free,
      • + *
    • safe to use across different runtime environments,
      • + *
    • independent of persistence, networking, or cryptographic providers.
      • + *
    + * + *

    Package structure

    + *

    + * The package is intentionally shallow at its top level and consists of: + *

    + *
      + *
    • A single direct utility class: {@link zeroecho.pki.util.PkiIds PkiIds}, + * which provides helper methods for creation and handling of PKI identifiers in + * a consistent and deterministic manner.
      • + *
    • Several subordinate utility subpackages, each grouping helpers for a + * specific technical concern (e.g. formatting, validation, or internal + * conventions), without polluting the top-level namespace.
      • + *
    + * + *

    Design principles

    + *

    + * Utilities in this package follow strict design rules: + *

    + *
      + *
    • no global mutable state,
      • + *
    • no hidden caching with externally visible effects,
      • + *
    • no dependency on environment-specific configuration,
      • + *
    • no leakage of sensitive material (keys, secrets, plaintext).
      • + *
    + * + *

    + * Where randomness or uniqueness is required (e.g. identifier generation), the + * semantics are explicitly documented and predictable within the guarantees of + * the underlying platform. + *

    + * + *

    Relation to other layers

    + *

    + * This package is deliberately orthogonal to: + *

    + *
      + *
    • API domain packages (such as {@code zeroecho.pki.api.*}),
      • + *
    • SPI and implementation layers,
      • + *
    • application bootstrap and orchestration code.
      • + *
    + * + *

    + * As such, utilities defined here may be freely reused by API, SPI, and + * implementation code without creating circular dependencies or architectural + * coupling. + *
