  }

  Current meta.json.

  • [key: string]: unknown

  • Optional_architect?: string

    Architect system prompt used this turn. Defaults from config.

  • Optional_architectTokens?: number

    Token count from last architect subprocess call.

  • Optional_architectTokensAvg?: number

    Exponential moving average of architect token usage (decay 0.3).

  • Optional_archived?: boolean

    Present and true on archive snapshots. Distinguishes live vs. archived metas.

  • Optional_archivedAt?: string

    Timestamp when this snapshot was archived. ISO 8601.

  • Optional_builder?: string

    Task brief generated by the architect. Cached and reused across cycles; regenerated only when triggered.

  • Optional_builderTokens?: number

    Token count from last builder subprocess call.

  • Optional_builderTokensAvg?: number

    Exponential moving average of builder token usage (decay 0.3).

  • Optional_content?: string

    Narrative synthesis output. Rendered by watcher for embedding.

  • Optional_critic?: string

    Critic system prompt used this turn. Defaults from config.

  • Optional_criticTokens?: number

    Token count from last critic subprocess call.

  • Optional_criticTokensAvg?: number

    Exponential moving average of critic token usage (decay 0.3).

  • Optional_crossRefs?: string[]

    Explicit cross-references to other meta owner paths. Referenced metas' _content is included as architect/builder context.

  • Optional_depth?: number

    Scheduling priority. Higher = updates more often. Negative allowed; normalized to min 0 at scheduling time.

  • Optional_emphasis?: number

    Emphasis multiplier for depth weighting in scheduling. Default 1. Higher values increase this meta's scheduling priority relative to its depth. Set to 0.5 to halve the depth effect, 2 to double it, 0 to ignore depth entirely for this meta.

  • Optional_error?: { code: string; message: string; step: "architect" | "builder" | "critic" }

    Structured error from last cycle. Present when a step failed. Cleared on successful cycle.

    • code: string

      Error classification code.

    • message: string

      Human-readable error message.

    • step: "architect" | "builder" | "critic"

      Which step failed: 'architect', 'builder', or 'critic'.

  • Optional_feedback?: string

    Critic evaluation of the last synthesis.

  • Optional_generatedAt?: string

    Timestamp of last synthesis. ISO 8601.

  • Optional_id?: string

    Stable identity. Auto-generated on first synthesis if not provided.

  • Optional_state?: unknown

    Opaque state carried across synthesis cycles for progressive work. Set by the builder, passed back as context on next cycle.

  • Optional_steer?: string

    Human-provided steering prompt. Optional.

  • Optional_structureHash?: string

    Hash of sorted file listing in scope. Detects directory structure changes that trigger an architect re-run.

  • Optional_synthesisCount?: number

    Cycles since last architect run. Reset to 0 when architect runs. Used with architectEvery to trigger periodic re-prompting.

• config: {
      architectEvery: number;
      architectTimeout: number;
      builderTimeout: number;
      criticTimeout: number;
      defaultArchitect?: string;
      defaultCritic?: string;
      depthWeight: number;
      gatewayApiKey?: string;
      gatewayUrl: string;
