+# Plan: ATM Eng Review — Findings Applied
+
+## Context
+
+User ran `/plan-eng-review` on `partitioned-honking-unicorn.md` (ATM trading monitor, Faza 1). Eng review complete. All 4 decisions resolved, obvious fixes applied, plan file updated in place.
+
+## Where the changes live
+
+The reviewed plan (with all eng-review edits) is at:
+**`/home/claude/.claude/plans/partitioned-honking-unicorn.md`**
+
+Test plan artifact at:
+**`~/.gstack/projects/romfast-workspace/claude-master-eng-review-test-plan-20260415-212932.md`**
+
+## What changed in the reviewed plan
+
+### 4 decisions (AskUserQuestion)
+1. **Bar flicker** → debounce depth=1 (configurable); screenshot in alert = visual check.
+2. **Phase A entry price** → dropped; Phase A is direction + screenshot only; user puts manual 0.6% SL in TradeLocker; Phase B sends real levels from chart.
+3. **Notifier blocking** → fire-and-forget worker threads per backend, bounded queue, retry + dead-letter.
+4. **Alert SPoF** → Discord + Telegram parallel from day 1.
+
+### Obvious fixes (stated, applied)
+- Exhaustive state transition table (default-noise rule, SELL mirror explicit, phase-skip handling).
+- Python 3.11+ pin → drop `tomli`, use stdlib `tomllib`.
+- Windows symlink replaced by `configs/current.txt` marker file.
+- New `vision.py` shared module (ROI/hash/interp/Hough).
+- `@dataclass Config` with load-time validation.
+- DPI check added to calibrate + README note.
+
+### Test coverage
+Expanded from state-machine-only to: every module + 1 E2E replay harness. Acceptance gate unchanged (precision=100%, recall≥95% on labeled corpus).
+
+## Verification (post-implementation)
+
+Run the full verification checklist from `partitioned-honking-unicorn.md` (sections 1-9). Specifically:
+- `pytest tests/` — all new unit tests + E2E replay pass.
+- `atm dryrun ./samples` hits acceptance gate.
+- Live 2-session test: both Discord and Telegram fire; kill one mid-session and confirm the other still delivers + dead-letter file gets the failed alert.
+
+## Status
+
+**CEO + ENG CLEARED.** No further reviews required before implementation. Design + DX reviews properly skipped (no UI scope; personal single-user tool). Run `/ship` after implementation.
