Core meaning
- Capability purpose
- Make long-running personal history navigable and meaningful without repeatedly flattening all raw evidence.
- Meaningful outcome
- A period summary captures themes, outcomes, changes, decisions, and unresolved threads and links to its contributing lower-level records.
- Boundaries — includes
- period definition, lower-level input selection, gap checks, synthesis, source links, hierarchy, closure, regeneration, and confidence/review state.
- Boundaries — excludes
- daily raw-evidence compilation, canonical event mutation, timeline UI rendering, and automatic promotion of inferred insights to truth.
- Terms and concepts
- Higher-period History composes bottom-up from closed lower-level summaries.
Interaction Contract MLEs
Compose a higher-period summary
- Actor
- An authorized History summarizer or owner.
- Command / intent
- Summarize a completed time period from accepted lower-level History.
- Current state
- Required lower-level periods are closed or their gaps are explicitly represented.
- Policies / invariants
- Inputs are linked; missing periods are not fabricated; higher levels do not silently reprocess unrelated raw sources; exclusions and sensitivity remain respected; corrections are versioned or attributable.
- Transition
- Validate period coverage, synthesize the lower-level records, and record hierarchy, provenance, confidence, and review state.
- Result
- A closed or reviewable period summary with drill-down links.
- Events / effects
- Supports temporal retrieval, reflection, planning, and later higher-level aggregation.
- Unknowns
- Universal closure timing and regeneration policy are not established.
Rules and defaults
Rules / invariants
- Weekly and higher summaries should be composed from accepted lower-level summaries.
- Aggregation must preserve access to the contributing periods and source trail.
Recommended defaults
- Increase abstraction with the period horizon while retaining decisions and unresolved themes.
Unknown / unresolved
- Whether monthly summaries compose from days or weeks may vary by implementation.
