Nexus Public Foundation

Use when porting Nexus Repository infrastructure contracts: freeze-aware task scheduling over Quartz, thread-scoped transactions with retry/backoff semantics, the capability lifecycle framework for plugin objects, blob-store location/soft-delete/S3 multipart mechanics, JWT-cookie sessions, double-submit CSRF, sandboxed JEXL/CSEL content selectors with parameterized SQL push-down, the repository view handler chain, and the plugin/boot/UI-extension system (descriptors, lifecycle phases, edition selection, script gating, state polling).

Nexus Repository 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: nexus-public; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@0a8a425daa4b37e924ca11e4637a41afce7b115c.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Task scheduling; Web security; Authorization core; Content selectors; Repository view pipeline; API layering; Transactional work units; Capability framework.
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.
