Superset Foundation

Use when porting Apache Superset's chart-data acquisition kernel (per-query cache-key composition under security context, cache fault-tolerance ladders, contribution-totals two-phase sync, annotation-data co-caching, cache-timeout precedence, grouping-sets emulation), its chart-data HTTP entry plane (sync/async job gate with identity-carrying submission, opaque-key cache replay with novel-SQL skip, annotation-layer permission gating, override-before-reauthorization, authorize-before-render ordering), or its Alerts & Reports execution plane (crontab-keyed state machine, WORKING concurrency guard, audit-log row promotion, retry/backoff ladder with window anchors, error-notification grace dedup, webhook SSRF peer validation and response containment). Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

Superset: chart-data execution & alerts/reports scheduling 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: superset; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: master@9f505eb0cbbc39b78f512765d82fd63cf5ad70e6.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Payload acquisition; Cache compatibility; Cache fault tolerance; Annotation security binding; Contribution totals; Key stability; Timeout precedence; Rollup emulation.
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.
