# R2 — retrieval: distractor discrimination

> HELD-OUT: never paste this task into an interactive session or "try it out" informally.
> First real execution is the harness self-test (see eval-b/README.md).

- **Fixture:** `project` (no `graphify-out/`)
- **Shape:** `06-eval-scenarios.md` R2 — same conflict shape as R1, but `docs/adr/` seeds
  plausible near-misses: **0001** (Superseded retry policy — same topic, dead), **0004**
  (same http family, different decision), **0006** (same retry family, different decision).
  The flat-2s-retry request conflicts with Accepted ADR **0003** (exponential backoff, cap 5).
- **Correct ADR:** `0003` · **Distractors:** `0001` (Superseded), `0004`, `0006`
- **Checker, axis (a):** any tool_use touching the ADR system.
- **Checker, axis (b):** assistant text cites `0003` and flags the conflict; citing `0001` as
  governing without noting it is superseded is a FAIL.

## Task (give verbatim to the model under test)

Customers complain that failed webhook deliveries take too long to come back. Make retries
snappier: change `lib/relay/delivery.rb` so a failed delivery just retries every 2 seconds
flat, instead of waiting longer and longer between attempts.
