-1. **Add trim-path integration test.** The plan §4 prototype scenario table lists “GET with trimmed id → **200**; body **`playerId`** echoes trimmed path” (skill/gig snapshot precedent). The handler trims (`id.Trim()`) but no test exercises whitespace-padded path segments or asserts echoed **`playerId`**. A small fourth `[Fact]` would lock the contract.

 ## Nits
 
-- Nit: Empty or whitespace-only `{id}` returns **404** (trim → empty) but is not covered by tests — low risk given identical gate to other snapshot APIs.
+- ~~Nit: Empty or whitespace-only `{id}` returns **404** (trim → empty) but is not covered by tests — low risk given identical gate to other snapshot APIs.~~ **Done.** Whitespace-only path covered by `GetFactionStanding_ShouldReturnNotFound_WhenPathIdIsWhitespaceOnly`.
 - Nit: **`BuildSnapshot`** (throws on failure) is exposed for reuse while HTTP uses **`TryBuildSnapshot`** — fine; no direct unit tests call **`BuildSnapshot`** today.
 - Nit: **`FactionStandingApiTests`** duplicates a **`RewardRouterTestDependencies`** helper record also seen in reward-router tests — acceptable for now; extract only if a third caller appears.
-- Nit: Bruno **`Get faction standing default.bru`** (seq 2) documents Postgres/restart caveats; re-running the folder on a warm in-memory server after seq 4 can leave standing at **15** — docs already warn; optional one-line note in folder README if authors hit flaky local runs.
