🟣 DRIFTBOUND_RETRIEVAL_OPERATOR

RTT/1 Operator Specification — archive_org Module#

Identity#

  • Operator Name: DRIFTBOUND_RETRIEVAL_OPERATOR
  • Operator Family: C‑Ops (Continuity Operators)
  • Module: archive_org
  • Purpose: Produce the final drift‑bounded retrieval, synthesizing all upstream operator outputs into a safe, continuity‑aligned answer.

Purpose (One Sentence)#

The DRIFTBOUND_RETRIEVAL_OPERATOR generates the final continuity‑aligned, substrate‑aware, drift‑bounded answer using all upstream operator outputs.


Inputs#

Input Type Description
snapshots list Time‑ordered captures from WAYBACK_OPERATOR.
drift_map object Structural drift levels between snapshots.
continuity_breaks list Gaps or discontinuities in the timeline.
lineage_graph object Structural evolution graph from LINEAGE_OPERATOR.
regime_shifts list Regime shift markers from LINEAGE_OPERATOR.
collection_id string Collection context from COLLECTION_OPERATOR.
coherence_clusters list Structural clusters from COLLECTION_OPERATOR.
related_objects list Related IA objects from COLLECTION_OPERATOR.
format string Substrate format from PRESERVATION_OPERATOR.
stability_score number Stability estimate from PRESERVATION_OPERATOR.
drift_risk string Expected drift level from PRESERVATION_OPERATOR.
multi_layer_flags list Substrate layers from PRESERVATION_OPERATOR.

Outputs#

Output Description
answer Final drift‑bounded retrieval.
earliest_stable_version First structurally stable snapshot.
most_reliable_version Snapshot with highest substrate stability.
key_changes Summary of major structural transformations.
warnings Drift, continuity, or substrate warnings.

Operator Guarantees#

  • No content‑based inference.
  • All reasoning is structural, not semantic.
  • Drift is explicit, never implied.
  • Continuity is preserved, never assumed.
  • Substrate stability is mandatory in the final answer.
  • Missing snapshots produce uncertainty, not assumptions.

Final Summary Requirements (RTT/1)#

Every drift‑bounded summary must include:

  1. Earliest stable version
  2. Most reliable version
  3. Key structural changes
  4. Continuity breaks (if any)
  5. Regime shifts (if any)
  6. Substrate stability + drift risk
  7. Warnings (mandatory if drift > none)

This is the canonical output contract for the entire module.


Operator Procedure#

  1. Identify earliest stable version using:
    • continuity kernel
    • drift_map
    • stability_score
  2. Identify most reliable version using:
    • substrate stability
    • multi_layer_flags
    • regime_profile
  3. Summarize structural changes using:
    • transformations
    • regime_shifts
    • drift_map
  4. Detect continuity issues using:
    • continuity_breaks
    • missing snapshots
  5. Generate drift‑bounded warnings.
  6. Produce final answer object.

Failure Modes#

  • No stable snapshots: return null + high‑drift warning.
  • Mixed substrates: require explicit layer‑aware warnings.
  • High drift: final answer must include caution.

Example (Synthetic)#

Input:
  snapshots = [2014, 2017, 2020, 2023]
  drift_map = { "2014→2017": "minor", "2017→2020": "high", "2020→2023": "minor" }
  continuity_breaks = []
  lineage_graph = { ... }
  regime_shifts = ["2020: static → CMS"]
  collection_id = "govdocs"
  format = "html + pdf"
  stability_score = 0.78
  drift_risk = "medium"

Output:
  earliest_stable_version = 2014
  most_reliable_version = 2023 (PDF layer)
  key_changes = ["CSS shift", "CMS migration", "PDF layer added"]
  warnings = ["High drift detected in 2017→2020", "HTML substrate is drift‑prone"]
  answer = "The most reliable version is the 2023 PDF snapshot..."

RTT/1 Mindset#

  • Retrieval is continuity‑aligned, not snapshot‑aligned.
  • Stability > recency.
  • Drift must be explicit.
  • Substrate determines trustworthiness.
  • No speculation.
  • No content‑based inference.
