docs(openup): migrate WI-1 artifacts from unversioned project-top docs/

work-items.md (project-management/), design-wi-1-injectable-rng.md
(analysis-design/), test-report-wi-1-injectable-rng.md (test/) move into
the canonical OpenUP home per the 2026-10-03 decision reversal. Verbatim,
no content changes; project-top docs/ husk removed.

+# WI-1 Test Report — Injectable RNG (skara-brae-server#1, PSP1)
+
+Date: 2026-10-02 · Phase: TST · Executor: agent (PM session, Kilo/glm-5.3)
+
+## Scope under test
+
+Branch `wi-1-injectable-rng` (uncommitted working tree vs base `64e081a`):
+`sb-core/src/character.rs` (create_character signature + new determinism test),
+`sb-api/src/routes/mod.rs` (request_rng helper, create handler, run_adventure
+consolidation).
+
+## Test cases
+
+| # | Test | Purpose | Result |
+|---|---|---|---|
+| 1 | `create_character_is_deterministic_under_seeded_rng` (NEW) | Two `StdRng::seed_from_u64(42)` runs yield identical stats (Debug-string) and equal hp/max_hp/energy/nerve — proves RNG injectability end-to-end | **pass** |
+| 2 | Existing sb-core suite (44 tests: character 20, combat 8, services 17 -1 overlap after adding #1) | No regression from signature change / rng threading | **pass** |
+| 3 | Acceptance audit: `grep -rn "rand::rng()" crates/` | Zero occurrences in the whole repo (incl. tests) — acceptance criterion | **pass** (only remaining entropy: `sb-auth/src/hash.rs:8` `getrandom::fill`, excluded by design) |
+| 4 | `cargo clippy --all-targets -- -D warnings` | Zero-warning standard | **pass** (clean) |
+| 5 | `cargo build --workspace` | Compile integrity | **pass** |
+| 6 | `rustfmt --check` (touched lines) | Coding standard on new/rewritten code | **pass** (repo-wide pre-existing fmt debt documented, not touched — see CMP log) |
+
+## Evidence
+
+- `cargo test --workspace`: **45 passed, 0 failed** (sb-core lib target; remaining targets empty)
+- Determinism test present and green: `test character::tests::create_character_is_deterministic_under_seeded_rng ... ok`
+- Full output captured in session log (PSP time log, TST phase, 2026-10-02 22:17)
+
+## Defects found in test phase
+
+None. (All defects D1–D11 were found in Design Review / Code / Code Review phases; see defect log.)
+
+## Notes
+
+- The new test replaced a whole-struct `Debug` comparison after D8 (HashMap iteration order instability) — comparison now covers the random-dependent state exactly.
+- No behavioral change expected from ThreadRng→StdRng: same distributions, one OS-entropy seeding per request (design rev 2, D1 correction).
