## [Unreleased]

### Changed
- **Office UI: DO-manual / OCR engine / require-plat temporarily hidden** —
  `templates/monitoring.html` `display:none` on the DO Manual mode button and the
  OCR Engine + Require plat meta rows. Hidden, not deleted: element IDs, JS
  handlers, and endpoints all stay intact, and `default_mode: manual` is the
  seed. Re-enable by dropping the three inline `display:none;` styles.
- **Rebrand: Karung.AI / Karung Counter → Feedmill Counting Platform** — UI page
  titles, header logo, footer, argparse description, systemd unit `Description`s,
  README/AGENTS headings. Header CSS shrunk below 640px so the longer brand name
  fits phone screens. Operational names unchanged on purpose: `OBJECT_LABEL`,
  DB paths, service unit filenames, repo/remote, and Indonesian UI/log strings
  (`karung`/`truk`).
- **Plate canonicalization** (`canonical_plate` in `src/do_batch.py`): plates are
  stored uppercase alnum-only (`B 1234 XYZ` / `b-1234.xyz` → `B1234XYZ`), so
  spacing/dot/hyphen variants are one plate everywhere — DB, history, XLSX, DO
  grouping (no more false `mixed_plates`). Render pretty (`B 1234 XYZ`) via
  `pretty_plate`. Applies to manual start, DO plate edit, DO OCR draft.
- `batch.default_mode` = **`manual`** (was `auto`) — auto mode merged many
  truck loads into one batch when a sack sat in the counting ROI (2026-10-03:
  2486 sacks / 7h14m in a single row). Operator page gets a manual-mode banner
  (plate → start when truck ready → stop when truck leaves).
- Manual start plate field warns (never blocks) when the value doesn't look like
  a plate.

### Added
- **Manual mode plate entry**: legacy `manual` batch start is now locked until a
  plate number is entered — plate input in operator + monitoring start modals
  (confirm button disabled while empty), `POST /api/batch/start` rejects
  manual start with 400 `missing_plate` (canonical + non-empty, no format regex);
  plate flows through `current_batch.json` → `batches.plate` on stop, so
  history/XLSX show it for manual batches. Operator plate tile now also shows
  for manual batches (was `do_manual` only).
- **DO-gated manual batch mode** (`manual` default · `do_manual` · `auto`):
  smartphone photo capture → OCR draft → plate-grouped start gates → net
  expected/counted on live panel → stop soft-warn + force → discard only when
  **both** gross `count` and `box_loading` are 0.
- `config.yaml` `batch.default_mode` + `do:` block; `DoConfig` in
  `src/config_loader.py`; runtime `$OUTPUT_DIR/do_settings.json`.
- `delivery_orders` table + additive `batches` columns (`plate`, `do_numbers`,
  `expected_*`, `net_*`); photo tree `do_photos/YYYY-MM-DD/` (7-day retention).
- APIs: `POST /api/batch/stop-preview`, DO CRUD + `POST /api/do/upload`,
  `GET|POST /api/do/settings` (all gated fields office-only:
  require_plate/require_do/**ocr_engine**, 403 on operator), office-only
  mode/model_mode POST (403 on operator; 409 when batch active).
- `src/do_batch.py` (pure gates/nets/units), `src/do_ocr.py`
  (`extract_do_fields` rapid|tesseract|paddle|none).
- **RapidOCR default engine** (`rapidocr_onnxruntime`, bundled PP-OCR models);
  tesseract + paddle kept as backups, explicit error if a dep is missing.
- Operator DO panel (no OCR toggle); monitoring 3-way mode switch + model mode +
  OCR selector with labels `RapidOCR (Default, Light & Accurate)` /
  `Tesseract (Backup, Light)` / `PaddleOCR (Accuracy, Heavy to run)` /
  `None (Manual)` + require-plate controls; history/export plate, DO,
  expected, net columns.
- `ERD.md` (Mermaid ERD, repo root; superseded `docs/do-erd.md`); tests `tests/test_do_batch.py`.
- History `Klip` button → office-only batch clip endpoints
  (`POST /api/batch-clip/<date>/<batch_number>` + `/status`, `/file`,
  `/pending`) trims+concatenates motionEye recordings to the batch window
  (`src/clip.py`), download `b<n>-<date>-<HH-MM-SS>.mp4`.
  - Async job processing: `Klip` → `Memproses…` (elapsed ticks, status polled
    every 1.5 s) → `Siap — unduh` (manual trigger, file already rendered) →
    `Unduh lagi` after the first download / `Gagal` (shows the job error).
    State restored from `/pending` on load, so it survives navigation/reload.
  - Non-blocking **`Klip siap`** / **`Klip gagal`** toast on all office pages
    (`templates/base.html` polls `/pending` every 3 s, sessionStorage dedupe,
    auto-dismiss 8 s, click → `/history`).
  - `MOTIONEYE_CLIP_PAD` (default ±3 s window padding) + OSD-clock alignment via
    single-frame OCR at each cut point (`MOTIONEYE_OSD_ALIGN`, default on).

### Fixed
- **Premature auto-batch finalization on big docked trucks** (batch 15 split
  `6` + `276`, 2026-09-29 14:07): truck gate now requires **≥50 % bbox
  overlap** with `detection_polygon` instead of 100 % containment — the docked
  truck's bbox rested 1–2 px past the polygon's bottom edge, so
  `truck_in_area` flickered `False` for 30 s while the truck never left.
  Frame replay with `v4-best.engine` detected the truck at conf 0.92–0.97 in
  **every** frame (no model miss → no retraining needed).
- `batch.truck_gone_tolerance_seconds` (new, default 30) is now the only
  truck-gone finalize timer: the hardcoded
  `batch_mgr._truck_gone_tolerance = 30.0` override in `predict.py` is gone,
  `batch.timeout_seconds` governs sack-idle pause only (comments inline in
  `config.yaml`), and `--batch-timeout` overrides both for dev runs.
- Added `[TRUCK] truck_in_area False -> True` transition debug log (state,
  valid-truck count, best bbox + conf) for future lifecycle incidents.

### Changed
- OCR engine default **`rapid`** (was `tesseract`) across `config.yaml`,
  `DoConfig`, `empty_do_settings`, `extract_do_fields`; `ocr_engine` write
  moved office-only (was both ports); OCR engine selector removed from
  operator page.
- Default batch mode seed **`auto`** (was hard-coded `manual` when
  `batch_mode.json` missing); `predict.py` accepts `do_manual` as operator-driven
  and persists sack `unloading` for net-at-stop.
- Finalize discard rule (dashboard stop **and** `predict.py` `finalize_batch`):
  keep row if **either** net ≠ 0 (box-only batches no longer dropped).
- Batch discard rule now gross-based: drop only when `count == 0` **and**
  `box_loading == 0` (was both nets 0 — kept rows like `count=0, unloading=7`).
- Event log wording: `masuk`/`keluar` now match event direction (unloading no
  longer logged as `masuk`, `TOTAL` line follows direction); wired the
  existing-but-unused `src/logger.py` `CSVLogger` into `predict.py`
  (`batch_summary.csv`, `sack_events.csv` under `output.dir`).

## 2026-09-18 — Config tuning: Sack confidence and batch timeout

### Changed
- `config.yaml`: Decreased `models.detection_params.sack.conf` from `0.35` to `0.30` for improved sack sensitivity.
- `config.yaml`: Decreased `batch.timeout_seconds` from `30.0` to `20.0` for faster batch cycle completion.
- `config.yaml`: Clarified deprecation note on `batch.merge_threshold_seconds`.

## 2026-09-17 — Unified `config.yaml` with extensible model presets

### Added
- `config.yaml` — single canonical config (stream, models, counting knobs,
  batch, output paths, camera). Secrets/deployment-only values stay in `.env`.
- `src/config_loader.py` — stdlib-dataclasses + pyyaml loader, zero new
  dependencies. Missing file falls back to `.env` + legacy defaults with a
  `UserWarning`; `MODEL_MODE` env still honoured once with a `DeprecationWarning`.
- `tests/test_config_loader.py` — 8 smoke tests (load/validate, precedence,
  atomic mode-switch round-trip, YAML-only mode-E extension, legacy warnings).
- Per-class `iou` and `min_bbox_area` in `models.detection_params`
  (shared across modes; `iou` default `0.7` = Ultralytics default, no behaviour change).
- `--config` CLI flag on `predict.py` (default: `config.yaml` next to `predict.py`).

### Changed
- **Model modes are data**: `config.yaml → models.modes` holds engines
  (path key + contributed classes) and class filters only. `predict.py`
  derives tracker roles structurally — adding mode E/F/... needs no code change,
  and the dashboard `/api/model-modes` lists new modes automatically.
- Dashboard `POST /api/batch/mode {"model_mode": "X"}` validates against
  `config.yaml` and persists atomically (tmp+replace, comments preserved) to
  `models.active_mode`. Manual `karung-counter` restart still required.
- `batch_mode.json` keeps only the manual/auto batch `mode`; its legacy
  `model_mode` key is ignored (warned when it disagrees).
- `zones.json` keeps geometry only (polygons + left/right limits); legacy knob
  keys there are ignored with a warning — `config.yaml counting.*` is canonical.
- `deploy_to_jetson.py` also syncs `config.yaml`.
- `src/tracking.py` / `src/detection.py` accept an `iou` parameter
  (default `0.7`, v3 callers unaffected).

## 2026-09-15 — Default model mode B → C

- Production default is now **Mode C** (combined v4 sack+truck + yolo11n
  box-only on a dedicated tracker) instead of Mode B (shared sack+box tracker).
  Changed in `predict.py`, `counter_dashboard.py`, `.env.example`, and docs.
  Sack path uses the proven v4 model; sack/box track-ID spaces no longer collide.

## 2026-09-14 — `models/modelREADME.md` rename

- `models/README.md` → `models/modelREADME.md` to avoid confusion with the
  root README. No content change.

## 2026-09-11 — Model weights tracked, per-mode matrix

- `models/*.pt` + `*.onnx` are now git-tracked (clone-ready); `*.engine`
  stays gitignored (rebuildable via `export_model.py` on the Jetson).
- All weights moved under `models/` with a per-mode detector/filter matrix
  (`models/modelREADME.md`); `predict.py` paths, `deploy_to_jetson.py`, and
  docs updated.
- Multi-model modes (A/B/C/D, default B at the time) + box counting +
  manual-mode banner (`6e4af50`).

## 2026-09-10 — Single `predict.py` entrypoint, experiments archived

- Production + dev CLI unified in `predict.py` (runs as `karung-counter.service`
  with zero args). Retired experiments moved to `archive/` via `git mv`
  (`predict_new.py`, `rpo_iki/`, `simple_predict.py`, check/merge/test scripts).
- Docs guides added (`docs/architecture.md`, `models.md`, `configuration.md`,
  `scripts.md`) plus DB/batch helper scripts; pytest smoke tests + CI.

## 2026-08-24 — Manual & auto batch modes, dual-port dashboards

- Manual/auto batch counting, operator (port 5000) + monitoring (port 5721)
  dashboards, historical batch data views and corrections.
