# Dub Foundation

> Use when building background-job dispatch on a hosted queue, webhook delivery with failure escalation, short-link redirect middleware (geo/device/AB/bot), bulk CRUD APIs that preserve order and report per-item errors, API error envelopes, cursor+offset pagination, policy rate limiting, Redis locks, or multi-rail partner payout processing (Stripe Connect/stablecoin/PayPal/gift-card) with commission aggregation, referral rewards, and partner postbacks.

# Dub 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: `dub`; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
- Recorded revision: `main@e3a558d1cf5d7aa10c366fb631ff7bc4295d8192`.
- Full provenance, coverage caveats, boundaries, and preserved evidence:
  `references/index.md`.

## Topic map

- Representative topics: Job dispatch; Job execution; Webhook trust; Error
  contract; Listing; Abuse control; Concurrency; Throughput utils.
- 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.
