Openhistory Foundation

Use when porting append-only JSONL event-store ingestion, bounded record schemas, incremental append caches with partial-write recovery, atomic in-place file rewrites, stateful privacy/redaction filters over timestamp-ordered event streams, task-episode segmentation with stable derived-record ids, provenance reconciliation of derived summary stores after source deletions, or evidence- calibrated LLM summarization gates that cap claims at what observations prove. Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

OpenHistory: local activity-history ingestion, projection & privacy foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: openhistory; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@daf7b073ce93673d0453d9f69b7435224c4bf49c.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Parse gate; Fail-soft loader; Bounded dedup walk; Append cache; Atomic scrub; Sticky boundary filter; Segmentation ladder; Episode identity.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
