Orchestrate P1 UI automation evaluations (#6, #7)

- recorder v1 (fail) → v2 (pass): drag state machine, focus events, ts/raw_coord
- player pass with caveats: reliability untestable in sandbox
- PROGRESS.md Done rows + follow-ups for live SUT smoke test
- PLAN.md P1 pivoted to test-runner + live smoke test

+# 2026-04-07 — Issue #7 player evaluator
+
+**Role:** Evaluator (independent)
+**Target:** `player`
+**Generator commit:** f17e764
+**Verdict:** pass with caveats
+
+## What I did
+
+1. Built `recordingtest.sln` -> 0 warn / 0 err.
+2. Ran `dotnet test tests/Recordingtest.Player.Tests` -> 6/6 pass.
+3. Read all player sources: `PlayerEngine.cs`, `IPlayerHost.cs`, `Program.cs`, `ScenarioLoader.cs`, `Model/Scenario.cs`, `Model/Step.cs`, `UiaPlayerHost.cs` (skim).
+4. Grep `Thread.Sleep(` and `Task.Delay(TimeSpan.FromSeconds` in `PlayerEngine.cs` -> 0 matches.
+5. Verified `Player_NoFixedSleep` is real: uses `[CallerFilePath]` to locate `src/Recordingtest.Player/PlayerEngine.cs` and regex-asserts absence of fixed sleeps.
+6. Mapped each DoD bullet to evidence and produced verdict table in `docs/contracts/player.evaluation.md`.
+
+## DoD scores
+
+| Item | Score |
+|---|---|
+| CLI args | pass |
+| wait_for | partial (PoC passthrough) |
+| resolve + offset | pass |
+| failure artifacts | pass |
+| checkpoint save | pass |
+| exit codes | pass |
+| 10/10 reliability | untestable (sandbox) |
+| no fixed sleep | pass |
+
+## Key findings
+
+- `PlayerEngine.ComputeScreenPoint` formula matches expected `bounds.X + W*ox`, verified by test (125,210 from 100/200 + 50*0.5 / 40*0.25).
+- `Program.cs` only supports `--no-launch` attach mode; launch path returns exit 5 with explicit message — generator was honest.
+- `wait_for` hint is forwarded to `IPlayerHost.WaitFor` with timeout; engine throws on timeout. Real waiting strategy lives in `UiaPlayerHost` (PoC).
+- `Model` classes mirror recorder yaml schema; `UnderscoredNamingConvention` handles `uia_path`, `after_step`, `save_as`, `startup_timeout_ms`.
+- Reliability (10x replay) cannot be measured here — no real SUT GUI in sandbox. Deferred, not failed.
+
+## Constraints respected
+
+- Did NOT modify generator code.
+- Did NOT update PROGRESS.md.
+- Only wrote `docs/contracts/player.evaluation.md` and this history file.
