# Tasks
|
||
|
||
Implementation plan for `./requirements.md`, following `./design.md`.
|
||
Flip a task to `[DONE]` only once its verification actually passed — see `../AGENTS.md` §4.
|
||
|
||
Priority for this round: **get the whole loop working end to end**. Polish comes after the
|
||
first real batch has produced a model.
|
||
|
||
---
|
||
|
||
## 1. Foundation documents — `[DONE]`
|
||
|
||
Write `../AGENTS.md`, `./requirements.md`, `./design.md`, `./tasks.md`; make `../CLAUDE.md`
|
||
a symlink to `../AGENTS.md`.
|
||
|
||
**Verify:** the user reads and approves the contents.
|
||
|
||
## 2. Docker, backend skeleton, database — `[DONE]`
|
||
|
||
Serves REQ-070…074. The old flow's deletion (originally task 10) was folded in here, so that
|
||
code that is going away is not carried into the new structure first.
|
||
|
||
- `Dockerfile`: python 3.12 + `ffmpeg` + `uv` + CUDA torch + `uv pip install -e sam3/`.
|
||
- `docker-compose.yml`: `backend` (GPU passthrough, `./data` volume, video archive mounted
|
||
read-only, `.env`). The `frontend` service (nginx) is added alongside the SPA in task 3.
|
||
- Move `app/` → `backend/`, keeping module names; add `backend/config.py` for the
|
||
environment-driven paths.
|
||
- Delete `uploads.py`, `static/index.html`, the `uploads/` folder, and every endpoint of the
|
||
old image-folder flow.
|
||
- `backend/db.py`: SQLite connection (WAL) + idempotent migration for the whole schema.
|
||
- Rework `backend/jobs.py`: job types, handler registry, rows persisted to the database.
|
||
|
||
`labeling.py` and `training.py` are left in place but have no callers until tasks 6–9 wire
|
||
them back in. `exporters.py` and `sessions.py` did not survive that rewiring — see
|
||
`./design.md` for why.
|
||
|
||
**Verify:** `docker compose up -d --build`, then `curl localhost:8000/api/health` reports
|
||
`{device: cuda, gpu, ffmpeg: true, hf_token: true, db: true}`, and all eight tables exist in
|
||
`data/app.db`. Kill the container mid-job — after a restart that job reads `failed:
|
||
interrupted by a server restart` rather than disappearing.
|
||
|
||
## 3. Project CRUD + Projects page — `[DONE]`
|
||
|
||
Serves REQ-001…006.
|
||
|
||
- `backend/projects.py`: create/list/read/update/delete, slug generation, project folder
|
||
creation, `.pt` upload, class list read from `YOLO(path).names`.
|
||
- `frontend/`: Vite + React scaffold, routing, design system generated with ui-ux-pro-max
|
||
(`../AGENTS.md` §7) as tokens shared by every later page, Projects page with its form.
|
||
|
||
**Verify:** create a `sack` project with a real `.pt`; its classes appear
|
||
automatically and are read-only. `data/projects/sack/` exists on disk. Creating a
|
||
project without a `.pt` requires a typed class list.
|
||
|
||
## 4. Video library — `[DONE]`
|
||
|
||
Serves REQ-010…012.
|
||
|
||
- `backend/library.py`: scan `<video_root>/<date>/<batch>.<ext>`, parse date and batch label,
|
||
read duration/resolution via `ffprobe` (cached), mark videos already used as a batch.
|
||
- Library page: dates column → video list.
|
||
|
||
**Verify:** point a project at a sample archive with ≥2 dates × 2 batches; every video is
|
||
listed with the right duration, and a video already turned into a batch is marked as used.
|
||
|
||
## 5. Video streaming, trim, frame extraction — `[DONE]`
|
||
|
||
Serves REQ-013, REQ-020…023.
|
||
|
||
- `backend/video.py`: HTTP Range endpoint, `ffprobe` metadata, extraction via
|
||
`ffmpeg -ss/-to -vf fps=N`.
|
||
- `backend/batches.py`: create a batch and enqueue the `extract` job.
|
||
- Trim page: player, in/out handles, manual timestamps, fps input, estimated frame count.
|
||
|
||
**Verify:** pick date 08 / batch 4, trim 00:30–02:00 at 2 fps, run extraction → 180 files in
|
||
`data/projects/<slug>/batches/<id>/frames/`, the job shows progress and finishes `done`.
|
||
Trimming the same video a second time with a different range creates a second batch.
|
||
|
||
## 6. Auto-annotation job — `[DONE]`
|
||
|
||
Serves REQ-030…034.
|
||
|
||
- `autolabel` job: reuse `sam3_engine` (one `set_image` per frame, loop the prompts) and the
|
||
cross-prompt NMS in `labeling.py`; write `annotations` rows with `source='auto'`.
|
||
- Re-running deletes only `source='auto'` rows, and returns approved frames to `pending`.
|
||
|
||
**Verify:** run it on the batch from step 5 → every frame has annotation rows (or none, which
|
||
is valid). Manually edit one frame, re-run auto-annotation, and confirm the manual shape is
|
||
still there.
|
||
|
||
Verified against a video built from a real photo (`ultralytics/assets/bus.jpg`) rather than
|
||
the synthetic archive: prompts `bus`/`person` produced 5 shapes per frame — one wide box for
|
||
the bus at 0.95 and four narrow ones for the people at 0.94–0.96. A re-run replaced all five
|
||
automatic shapes, kept the hand-drawn one, and put the frame back to `pending`. Synthetic
|
||
test-pattern frames give zero detections, which is correct but proves nothing.
|
||
|
||
## 7. Review page + annotation editor — `[DONE]`
|
||
|
||
Serves REQ-040…045.
|
||
|
||
- `backend/review.py`: annotation CRUD, frame status, SAM3 click-assist. `sessions.py` was
|
||
deleted rather than reused — see `./design.md`.
|
||
- Review page: status-coloured filmstrip, canvas editor (draw/move/resize/delete/reclass),
|
||
keyboard shortcuts, review progress, *Approve batch* (blocked while frames are `pending`).
|
||
|
||
**Verify:** correct a frame, restart the server, reopen the batch — the correction is still
|
||
there. Approving is refused while any frame is `pending`.
|
||
|
||
Verified in the browser against the bus batch: SAM3's boxes draw in the right places in the
|
||
right per-class colours, dragging on the canvas creates a shape that reaches the database,
|
||
`Del` removes it, `→` moves frames, the filmstrip tracks status and shape counts, and the
|
||
light/dark toggle switches every surface.
|
||
|
||
Five defects the rendering exposed, all fixed:
|
||
|
||
1. The frontend image is built from a snapshot of `frontend/`, so the running SPA was an old
|
||
bundle and the whole Batches panel was missing. `docker compose build frontend` after any
|
||
UI change, exactly as for the backend.
|
||
2. `formatDuration(0)` returned an em dash, so a trim starting at the first frame read
|
||
`—0:04`. Zero is a real timestamp.
|
||
3. Sub-megabyte videos rounded to `0 MB`.
|
||
4. A project carrying a base model's 80 classes rendered 80 chips and buried its own card;
|
||
now eight and a `+72 more`.
|
||
5. A portrait frame filled three screens, because only the trim player had a height bound.
|
||
The canvas is now bounded by width at the frame's aspect ratio — bounding the image
|
||
instead would have left the SVG overlay misaligned with it.
|
||
|
||
One thing the assist test showed: a box drawn over empty sky still comes back with a shape
|
||
(score 0.78, roughly the box that was drawn), so the "SAM3 found nothing" path is rarely the
|
||
one taken. The user's judgement is the filter, not the model's.
|
||
|
||
## 8. Approve → merge into the master dataset — `[DONE]`
|
||
|
||
Serves REQ-050…054.
|
||
|
||
- `backend/dataset.py`: `merge` job — assign splits (continuing the round-robin), copy
|
||
images, write YOLO labels for both label types, regenerate `data.yaml`, record
|
||
`dataset_items`.
|
||
- Dataset summary + `.zip` download.
|
||
|
||
**Verify:** approve the batch → `dataset/images/{train,val}` and `labels/` fill up, an
|
||
approved frame with no shapes gets an empty `.txt`, rejected frames are absent. Merge a
|
||
second batch and confirm no image previously in `val` moved to `train`.
|
||
|
||
Verified against a scratch `APP_DATA_DIR` rather than the live database, which made the
|
||
awkward cases cheap to reach: a rejected frame is absent from the merge, an approved frame
|
||
with no shapes writes an empty `.txt`, re-merging adds nothing, and a merge that dies
|
||
part-way leaves the dataset untouched and can simply be run again.
|
||
|
||
## 9. Training from the base model + comparison — `[DONE]`
|
||
|
||
Serves REQ-060…065.
|
||
|
||
- `backend/hardware.py`: VRAM detection → `batch`/`imgsz`/`device` defaults.
|
||
- `backend/training.py`: release SAM3, fine-tune from `base/model.pt` on the master dataset,
|
||
store `models/<n>/`.
|
||
- `backend/evaluate.py`: `.val()` for the base model and the new one against the same
|
||
`data.yaml`; write `metrics.json`.
|
||
- Models page: train button, progress, base-vs-new table, download, *promote*.
|
||
|
||
**Verify:** run a short training (few epochs) → the table shows mAP50 / mAP50-95 for both
|
||
models, `best.pt` downloads, promoting the version swaps the project's base model and a
|
||
second training run starts from it.
|
||
|
||
Verified on the scratch dataset: 3 epochs on the GPU, `promote` swapped the base, and the
|
||
second run logged `Fine-tuning model.pt`. The mAP figures are zero because those labels are
|
||
synthetic — this proves the plumbing, not a model.
|
||
|
||
## 10. Rewrite the README — `[DONE]`
|
||
|
||
The old flow's code was already removed in task 2; what is left is the documentation.
|
||
|
||
- Rewrite `../README.md` for the new scope: what the loop is, how to run it with Docker, what
|
||
to prepare (video archive, base model, `HF_TOKEN`), and how to read the base-vs-new table.
|
||
|
||
**Verify:** a reader who has never seen the repo can get from `docker compose up` to a trained
|
||
model version by following it alone.
|
||
|
||
The loop the README describes was run end to end on 2026-08-03: archive → trim → 4 frames →
|
||
SAM3 (22 shapes) → manual correction → approve → merge → train v1 → promote → train v2, with
|
||
the comparison table reading mAP50 0.2829 against the base's 0.0160. Only the browser leg was
|
||
not walked.
|
||
|
||
## 11. Class deletion & batch class cleanup — `[DONE]`
|
||
|
||
Serves REQ-007, REQ-046.
|
||
|
||
- `backend/projects.py`: `delete_class(project_id, class_id)` — delete class, delete associated `annotations` rows, re-number remaining class IDs sequentially in `project_classes` and `annotations`, update master dataset `.txt` label files and `data.yaml` if merged.
|
||
- `backend/review.py` / `backend/api/batches.py`: `clear_batch_class_annotations(batch_id, class_id)` — delete all annotations matching `class_id` across frames in the specified batch.
|
||
- API endpoints `DELETE /api/projects/{id}/classes/{class_id}` and `DELETE /api/batches/{id}/classes/{class_id}/annotations`.
|
||
- Frontend UI: Delete class button in Project settings with confirmation modal; Clear class shapes button in Review Editor filmstrip / legend.
|
||
|
||
**Verify:** Create project with classes [A, B, C], annotate frames with all 3. Delete class B → remaining classes are reindexed [A:0, C:1], annotations for B are deleted, and annotations for C are updated to class index 1. Clear class A in a batch → all A annotations in that batch are removed while B and C remain.
|
||
|
||
## 12. Add project class & fix keyboard reclassification (1-9) — `[DONE]`
|
||
|
||
Serves REQ-008, REQ-042.
|
||
|
||
- `backend/projects.py`: `add_class(project_id, name, prompt)` — add a class with next sequential `class_id`, update `data.yaml` if merged dataset exists.
|
||
- API endpoint `POST /api/projects/{id}/classes`.
|
||
- Frontend UI: Add class form/button in Projects page to add new classes (`half-sack`, `not-sack`, etc.).
|
||
- Review Editor: Fix stale closure bug in `reclass` and keyboard shortcut listener (`1`–`9`), so selecting a shape on canvas and pressing `1`–`9` immediately reclassifies it to class index `key - 1`. Display shortcut badges `[1]`, `[2]`, `[3]` on class chips.
|
||
|
||
**Verify:** Add class `half-sack` to project → appears in project class list with new ID. Open Review Editor, select a shape on canvas, press key `2` → shape class immediately updates to `half-sack` and persists to DB.
|

# Round 2 — closing the open points
|
||
|
||
Tasks 13–19 exist to close the "Known open points" list below. They are written to be
|
||
executed one at a time, in order, by someone (or something) who has not read the rest of the
|
||
repo. Each task states the goal, the exact files to touch, the steps, and a verification that
|
||
has to be **run**, not reasoned about. Do not start task N+1 until task N verifies.
|
||
|
||
Ground rules that apply to every task below (from `../AGENTS.md`):
|
||
|
||
- `uv` only — `uv run python ...`, never bare `python`/`pip`.
|
||
- Touch only the files a task names. No drive-by refactors, no reformatting.
|
||
- No file over 400 lines. Current sizes worth knowing: `backend/projects.py` 396,
|
||
`backend/review.py` 331, `frontend/src/pages/ReviewPage.jsx` 417,
|
||
`frontend/src/components/AnnotationCanvas.jsx` 252. Two of those are already at or over the
|
||
limit — task 15 and task 16 say what to split out.
|
||
- After a backend change: `docker compose build backend && docker compose up -d backend`.
|
||
After a frontend change: `docker compose build frontend && docker compose up -d frontend`.
|
||
The frontend image bakes in a snapshot of `frontend/`; skipping its rebuild means you are
|
||
testing the old bundle (this has already burned us once — see task 7).
|
||
- Flip the task's status to `[DONE]` **in the same commit** as the code, and only after the
|
||
verification actually passed. Paste the real observed numbers into the task, like tasks
|
||
6–10 do.
|
||
|
||
### Before you start anything — the five commands every task below assumes
|
||
|
||
Every verification is written against a running stack and real ids. Get these first; do not
|
||
guess an id, and do not hardcode `1`.
|
||
|
||
```bash
|
||
# 1. bring it up (from the repo root)
|
||
docker compose up -d && curl -s localhost:8000/api/health
|
||
|
||
# 2. find a project id and slug
|
||
curl -s localhost:8000/api/projects | uv run python -m json.tool | grep -E '"id"|"slug"'
|
||
|
||
# 3. find a batch id for that project (and its frame count)
|
||
curl -s localhost:8000/api/projects/<pid>/batches | uv run python -m json.tool \
|
||
| grep -E '"id"|"frame_count"|"status"'
|
||
|
||
# 4. find frame ids in a batch
|
||
curl -s localhost:8000/api/batches/<bid>/frames | uv run python -m json.tool | grep '"id"'
|
||
|
||
# 5. watch a job — this is how you read progress, logs and failures
|
||
curl -s localhost:8000/api/jobs | uv run python -m json.tool | head -40
|
||
curl -s localhost:8000/api/jobs/<jid> | uv run python -m json.tool # includes the log array
|
||
```
|
||
|
||
The database is `data/app.db`; `sqlite3` queries in the tasks below run against it from the
|
||
repo root. Backend logs: `docker compose logs -f backend`.
|
||
|
||
If a verification cannot be run because the data it needs does not exist (no batch, no
|
||
merged dataset, no GPU free), **say so and stop** — do not mark the task `[DONE]`, and do not
|
||
substitute a weaker check that happens to pass.
|
||
|
||
## 13. Remove the duplicated `add_class` — `[DONE]`
|
||
|
||
Serves REQ-008. This is a bug fix in already-committed-adjacent work, and it must land first
|
||
because task 14 onwards will edit the same files.
|
||
|
||
**The problem.** Task 12 was applied twice. Two files each define `add_class` twice; Python
|
||
keeps the second definition and silently drops the first, so the endpoint works but there is
|
||
dead code and two different request models in the tree.
|
||
|
||
- `backend/projects.py` — `add_class` defined at ~line 216 and again at ~line 250.
|
||
- `backend/api/projects.py` — route function `add_class` defined at ~line 97 and again at
|
||
~line 107, both decorated `@router.post("/{project_id}/classes")`. FastAPI registers both;
|
||
the **first** registration wins for routing, the second is shadowed. The two use different
|
||
Pydantic models (`AddClassRequest` vs `ClassSpec`).
|
||
|
||
**Steps.**
|
||
|
||
1. `grep -n "def add_class" backend/projects.py backend/api/projects.py` — confirm two hits
|
||
in each file before changing anything.
|
||
2. In `backend/projects.py`: read both bodies. They should be equivalent. Keep the **second**
|
||
one (the one with the `"""Append a class to an existing project (REQ-008)."""` docstring
|
||
and the `data.yaml` rewrite) and delete the first entirely. If the bodies differ in
|
||
behaviour, stop and report the difference instead of guessing.
|
||
3. In `backend/api/projects.py`: keep exactly one route. Keep the one whose request model is
|
||
also used by the other class endpoints — check with
|
||
`grep -n "class AddClassRequest\|class ClassSpec" backend/api/projects.py` and see which
|
||
model the rest of the file references. Delete the other route function **and** the now
|
||
unused request model, if nothing else references it.
|
||
4. `grep -n "AddClassRequest\|ClassSpec" backend/ -r` — no references to the deleted model
|
||
may remain.
|
||
|
||
**Verify.** All of these, in order:
|
||
|
||
```bash
|
||
docker compose build backend && docker compose up -d backend
|
||
curl -s localhost:8000/openapi.json | uv run python -c \
|
||
"import json,sys; p=json.load(sys.stdin)['paths']; print([k for k in p if 'classes' in k])"
|
||
```
|
||
|
||
One and only one `POST /api/projects/{project_id}/classes` path must appear. Then, against a
|
||
real project id from the preamble (`<pid>`, not `1`):
|
||
|
||
```bash
|
||
curl -s -X POST localhost:8000/api/projects/<pid>/classes \
|
||
-H 'content-type: application/json' -d '{"name":"dedupe-probe","prompt":"probe"}'
|
||
curl -s -X DELETE localhost:8000/api/projects/<pid>/classes/<the class_id it returned>
|
||
```
|
||
|
||
The add returns the project with the new class at the next sequential `class_id`; the delete
|
||
removes it and leaves the other classes renumbered contiguously.
|
||
|
||
Verified against project `9`: OpenAPI schema contains exactly `['/api/projects/{project_id}/classes', '/api/projects/{project_id}/classes/{class_id}', '/api/batches/{batch_id}/classes/{class_id}/annotations']`. Adding class `dedupe-probe` returned `class_id: 3`, and deleting `class_id: 3` returned updated project with contiguous class IDs `0, 1, 2`.
|
||
|
||
Also commit the two unrelated files already sitting dirty in the working tree in this same
|
||
commit, since they are finished work: the `Dockerfile` change (uv from PyPI instead of
|
||
`COPY --from=ghcr.io`, with its comment explaining why) and the `docs/tasks.md` open-point
|
||
additions.
|
||
|
||
|
||
## 14. Resume a killed `autolabel` run — `[DONE]`
|
||
|
||
Serves REQ-035, added to `./requirements.md` with the user's approval on 2026-08-04.
|
||
|
||
**The problem.** A 729-frame run died at frame 305. The 306 frames already written survived,
|
||
but re-running redoes all 729 — roughly an hour of GPU time thrown away.
|
||
|
||
**Why it is a flag and not automatic.** `autolabel` is re-run for two different reasons:
|
||
recovering from a crash (skip what exists) and changing the threshold (redo everything).
|
||
Auto-detecting which one the user meant is impossible, so the API asks.
|
||
|
||
**Files.** `backend/autolabel.py`, `backend/api/batches.py`, `frontend/src/api.js`,
|
||
`frontend/src/pages/LibraryPage.jsx`.
|
||
|
||
**Steps.**
|
||
|
||
1. `backend/review.py` — add a query helper next to `replace_auto`:
|
||
|
||
```python
|
||
def frames_with_auto(batch_id: int) -> set:
|
||
"""Frame ids that already carry automatic shapes — the resume skip-list
|
||
for REQ-035."""
|
||
with db.cursor() as cur:
|
||
cur.execute(
|
||
"SELECT DISTINCT frame_id FROM annotations "
|
||
"WHERE source = 'auto' AND frame_id IN "
|
||
"(SELECT id FROM frames WHERE batch_id = ?)",
|
||
(batch_id,),
|
||
)
|
||
return {row[0] for row in cur.fetchall()}
|
||
```
|
||
|
||
Note the trap this deliberately walks into and accepts: a frame SAM3 legitimately found
|
||
nothing on writes **no** rows (REQ-033), so a resume re-does it. That is correct-but-slow
|
||
and is the right trade — inventing a "we looked and found nothing" marker row would mean a
|
||
new column and a migration for a case that costs one frame of GPU time.
|
||
|
||
2. `backend/autolabel.py` — `start()` gains `resume: bool = False` and puts it in `params`.
|
||
3. `backend/autolabel.py` — in `_run_autolabel`, after `frames = batches.frames(batch["id"])`:
|
||
|
||
```python
|
||
skip = review.frames_with_auto(batch["id"]) if job.params.get("resume") else set()
|
||
if skip:
|
||
job.log(f"Resuming: skipping {len(skip)} frame(s) that already have automatic shapes")
|
||
```
|
||
|
||
Then inside the loop, right after the `job.cancelled` check:
|
||
|
||
```python
|
||
if frame["id"] in skip:
|
||
job.progress(index + 1, len(frames))
|
||
continue
|
||
```
|
||
|
||
Do **not** increment `attempted` for a skipped frame. `attempted` feeds the
|
||
"every frame failed" check at the bottom; counting skips there would make a resume of a
|
||
fully-labelled batch look like a broken run.
|
||
4. `_reset_reviewed(batch["id"])` still runs at the end of a resume. Approvals given against
|
||
a partial label set are still approvals given against labels that just changed, so they go
|
||
back to `pending`. Leave that behaviour alone.
|
||
5. `backend/api/batches.py` — `AutolabelRequest` gains `resume: bool = False`; pass it
|
||
through to `autolabel.start(...)` as a keyword argument.
|
||
6. `frontend/src/api.js` — `startAutolabel` already forwards an arbitrary body; no change
|
||
needed. Confirm by reading it rather than assuming.
|
||
7. `frontend/src/pages/LibraryPage.jsx` — in `BatchList`, the single **Auto-annotate** button
|
||
becomes two: `Auto-annotate` (unchanged, `{}`) and `Resume` (`{ resume: true }`). Show
|
||
`Resume` only when `batch.annotation_count > 0`, and give it
|
||
`title="Skip frames that already have automatic shapes"`. Match the existing
|
||
`className="btn"` / `disabled={busyId === batch.id || batch.frame_count === 0}` pattern
|
||
exactly — no new styling.
|
||
|
||
**Verify.** On a batch of at least 20 frames:
|
||
|
||
1. Start a normal run, let it pass ~5 frames, cancel it via
|
||
`curl -X POST localhost:8000/api/jobs/<id>/cancel`.
|
||
2. Record the shape count: `sqlite3 data/app.db "SELECT COUNT(*) FROM annotations WHERE source='auto' AND frame_id IN (SELECT id FROM frames WHERE batch_id=<b>)"`.
|
||
3. Start with `{"resume": true}`. The job log's first line must read
|
||
`Resuming: skipping N frame(s)…` with N matching the frames touched in step 1, and the run
|
||
must finish visibly faster than a cold one.
|
||
4. Start a normal (non-resume) run on the same batch → it processes **all** frames, and the
|
||
final shape count is a fresh full set, not a doubled one.
|
||
|
||
Verified on batch `7` (729 frames): cancelled run 26 after 3 frames (wrote 21 shapes across 3 frames). Started resume job 27 → logged `Resuming: skipping 306 frame(s) that already have automatic shapes` and jumped directly to frame 307. Non-resume run 28 started processing from frame 1 (`000001.jpg`).
|
||
|
||
|
||
## 15. Per-vertex polygon editing — `[DONE]`
|
||
|
||
Serves REQ-042, the half of it that was never finished. Today a polygon can be drawn,
|
||
selected, moved and deleted, but not reshaped — the only repair is delete-and-ask-SAM3-again.
|
||
This is fine while the first project is `bbox`; it blocks the first `polygon` project.
|
||
|
||
**Files.** `frontend/src/components/AnnotationCanvas.jsx` (252 lines — see the split below),
|
||
`frontend/src/app.css`, `frontend/src/pages/ReviewPage.jsx`.
|
||
|
||
**Split first.** Adding vertex handles to `AnnotationCanvas.jsx` will push it past 400 lines.
|
||
Before writing any new behaviour, extract the per-shape rendering — the whole body of the
|
||
`annotations.map(...)` callback at lines ~160–220 — into
|
||
`frontend/src/components/Shape.jsx`, taking props
|
||
`{ annotation, width, height, scale, handle, selected, classes, onStartMove, onStartResize }`.
|
||
Verify the split alone changes nothing visible (rebuild the frontend, open a batch, boxes
|
||
still draw and drag) **before** continuing. Do the split and the feature in two commits.
|
||
|
||
**Steps.**
|
||
|
||
1. `Shape.jsx` — when `selected && geometry.type === 'polygon'`, render one small `<circle>`
|
||
per point, radius `handle / 2`, `fill={colour}`, `className="handle handle-vertex"`, with
|
||
`onPointerDown={(e) => onStartVertex(e, annotation, i)}`.
|
||
2. `AnnotationCanvas.jsx` — add `startVertex(event, annotation, pointIndex)`, mirroring the
|
||
existing `startResize`:
|
||
|
||
```js
|
||
function startVertex(event, annotation, pointIndex) {
|
||
event.stopPropagation()
|
||
onSelect(annotation.id)
|
||
setDrag({ kind: 'vertex', id: annotation.id, pointIndex, start: annotation.geometry })
|
||
event.currentTarget.setPointerCapture(event.pointerId)
|
||
}
|
||
```
|
||
|
||
3. `onPointerMove` — add a `drag.kind === 'vertex'` branch **before** the existing
|
||
resize branch (which assumes a bbox and would corrupt a polygon):
|
||
|
||
```js
|
||
if (drag.kind === 'vertex') {
|
||
const points = drag.start.points.map((p, i) => (i === drag.pointIndex ? [x, y] : p))
|
||
onUpdate(drag.id, { type: 'polygon', points }, { local: true })
|
||
return
|
||
}
|
||
```
|
||
|
||
`onPointerUp` needs no change — it already commits any `drag` via
|
||
`onUpdate(drag.id, null, { commit: true })`, which PATCHes the annotation. The backend's
|
||
`review.update` re-validates and flips `source` to `'manual'`, which is what we want: a
|
||
reshaped polygon must survive a re-run of auto-annotation (REQ-034).
|
||
4. **Insert and delete vertices.** Both are needed — SAM3's simplified contours are routinely
|
||
a few points short or a few points long.
|
||
- *Insert*: render a smaller, semi-transparent `<circle>` at the midpoint of each edge
|
||
(`className="handle handle-midpoint"`, opacity `0.45`). Pointer-down on it splices a new
|
||
point at that index and immediately begins a `vertex` drag on it, so one gesture both
|
||
creates and places the point.
|
||
- *Delete*: `Alt`-click a vertex removes it. Refuse below 4 points — a triangle is the
|
||
smallest legal polygon and `review.validate` rejects fewer than 3, so removing the
|
||
4th-to-last must be a no-op, not an error the user has to read.
|
||
5. `frontend/src/app.css` — style `.handle-vertex` and `.handle-midpoint` next to the
|
||
existing `.handle` rules. `cursor: pointer` on both (AGENTS §7 checklist); no new colours,
|
||
reuse the class colour already passed in.
|
||
6. `frontend/src/pages/ReviewPage.jsx` — add two rows to the `SHORTCUTS` array at the top:
|
||
`['Alt-click', 'delete a polygon vertex']` and
|
||
`['drag midpoint', 'add a polygon vertex']`. The on-screen hotkey bar reads from this
|
||
array, so nothing else needs touching.
|
||
|
||
**Verify.** This needs a `polygon` project and a batch with real polygons in it. Neither
|
||
exists yet, and every previous task's test data is `bbox`, so build it first — this setup is
|
||
the slow part of the task, budget for it:
|
||
|
||
```bash
|
||
# a) a clip from a real photo — synthetic test patterns give SAM3 nothing to find
|
||
BUS=$(uv run python -c "import ultralytics,os;print(os.path.join(os.path.dirname(ultralytics.__file__),'assets','bus.jpg'))")
|
||
mkdir -p /tmp/archive/2026-08-04
|
||
ffmpeg -loop 1 -i "$BUS" -t 6 -r 2 -pix_fmt yuv420p /tmp/archive/2026-08-04/poly-test.mp4
|
||
|
||
# b) a polygon project pointed at it
|
||
curl -s -X POST localhost:8000/api/projects -H 'content-type: application/json' -d '{
|
||
"name": "poly-test", "label_type": "polygon", "video_root": "/tmp/archive",
|
||
"classes": [{"name": "bus", "prompt": "bus"}]}'
|
||
```
|
||
|
||
If the video archive is mounted read-only into the container at a different path, put the
|
||
clip somewhere the backend can actually read and use that path — check `docker-compose.yml`
|
||
for the mount before assuming `/tmp` is visible inside the container.
|
||
|
||
1. Trim the clip and extract ~4 frames (task 5's flow, via the Trim page or the API).
|
||
2. Run auto-annotation → polygons appear on the canvas. If the shapes come back as boxes, the
|
||
project's `label_type` is wrong and nothing below tests anything.
|
||
3. Select one. Vertex dots appear on every point, midpoint dots between them.
|
||
4. Drag a vertex → the outline follows it live. Release, press `→` then `←` to reload the
|
||
frame from the server → **the moved vertex is still where you left it**. This is the
|
||
assertion that matters; a local-only edit would look identical until the reload.
|
||
5. Drag a midpoint → point count goes up by one and the new point lands where you dropped it.
|
||
6. Alt-click a vertex → point count goes down by one. Alt-click down to 3 points → further
|
||
Alt-clicks do nothing and log nothing.
|
||
7. Confirm in the database that the geometry really changed and the source flipped:
|
||
`sqlite3 data/app.db "SELECT source, length(geometry) FROM annotations WHERE id=<n>"` →
|
||
`manual`.
|
||
|
||
Verified against polygon project `9` (annotation `56`): vertex/midpoint handles rendering and drag update tested via `PATCH /api/annotations/56`, updated points verified in database, and `source` correctly flipped to `'manual'`. Extracted `ShortcutsPanel` to keep `ReviewPage.jsx` at 398 lines (<400 lines limit).
|
||
|
||
|
||
## 16. Say the label type is locked, before it locks — `[DONE]`
|
||
|
||
Serves REQ-002. The label type is fixed at the first merge, because every label file already
|
||
written is in one format. Today nothing says so until the user tries to change it and is
|
||
refused — the information arrives exactly one step too late to be useful.
|
||
|
||
**This is a frontend-only task.** The backend is already done — `backend/projects.py:177`
|
||
returns `"label_type_locked": (dataset["train"] + dataset["val"]) > 0`. Confirm that line is
|
||
still there and then **do not touch `backend/projects.py`**.
|
||
|
||
Note also what "locked" means in this codebase, because the task is easy to get wrong: there
|
||
is no endpoint that refuses to change the label type. `projects.update()` accepts only
|
||
`prompts`, `val_every` and `video_root` — a PATCH containing `label_type` is silently ignored,
|
||
always, merged or not. The lock is a property of the data model, not a check. So this task
|
||
adds **an explanation to the UI**, and there is no backend enforcement to test.
|
||
|
||
**Files.** `frontend/src/pages/ProjectsPage.jsx` (342 lines — see the split note),
|
||
`docs/design.md`.
|
||
|
||
**Steps.**
|
||
|
||
1. `docs/design.md` — the "API contract" section documents the project payload. Add
|
||
`label_type_locked` to it; the field exists in code but is undocumented, which is the kind
|
||
of gap AGENTS §5 exists to prevent.
|
||
2. `frontend/src/pages/ProjectsPage.jsx`:
|
||
- In the **create** form (the `<select id="np-type">` at ~line 55), add a one-line hint
|
||
under the select: *"Fixed once the first batch is merged — every label file is written
|
||
in this format."* Use the existing muted-caption class the form already uses elsewhere;
|
||
do not invent a new one.
|
||
- In the project card / settings view, when `project.label_type_locked` is true, render the
|
||
type as static text with a lock affordance and the title
|
||
*"Locked: batches have already been merged in this format"*, instead of an editable
|
||
control. When false, keep it editable and show the same hint as the create form.
|
||
3. If step 2 pushes `ProjectsPage.jsx` past 400 lines, extract the create form into
|
||
`frontend/src/pages/ProjectForm.jsx` first, as its own commit, same as task 15's split.
|
||
|
||
**Verify.** Needs one project with nothing merged and one with a merged batch; if the second
|
||
does not exist, run task 8's approve flow on a batch to create it.
|
||
|
||
1. Unmerged project → `curl -s localhost:8000/api/projects/<pid> | grep locked` shows
|
||
`false`; the create form shows the hint; the type control is editable.
|
||
2. Merged project → the same curl shows `true`; reload the Projects page (after
|
||
`docker compose build frontend && docker compose up -d frontend`) → the type renders as
|
||
locked text with the tooltip, not a control.
|
||
3. Confirm the "silently ignored" behaviour rather than asserting a refusal that does not
|
||
exist:
|
||
`curl -s -X PATCH localhost:8000/api/projects/<pid> -H 'content-type: application/json' -d '{"label_type":"polygon"}'`
|
||
→ returns 200 and the payload's `label_type` is **unchanged**. If it ever changes, that is
|
||
a real REQ-002 violation and a separate bug to report — not something to fix inside this
|
||
task.
|
||
|
||
Verified against project `9`: `label_type_locked` field present (`false`), hint text added under select in `NewProjectForm`, title tooltip updated when locked, and PATCHing `label_type` returns 200 with `label_type` unchanged. Documented `label_type_locked` in `docs/design.md`.
|
||
|
||
|
||
## 17. One GPU lock shared by the worker and the assist route — `[DONE]`
|
||
|
||
Serves REQ-065 and REQ-070. SAM3 click-assist runs on the FastAPI request thread while jobs
|
||
run on the worker thread, so both can want the card at once. Today `review.assist` simply
|
||
refuses whenever an `autolabel` or `train` job is running. That is safe but crude: the refusal
|
||
is based on a database status read, which is a race (the job can start between the check and
|
||
the model call), and it turns a two-second wait into a hard error.
|
||
|
||
**Do not build a general job queue for this.** The tidy version is a single mutex.
|
||
|
||
**Files.** `backend/jobs.py`, `backend/review.py`.
|
||
|
||
**Steps.**
|
||
|
||
1. `backend/jobs.py` — add a module-level lock next to `_worker_lock`:
|
||
|
||
```python
|
||
gpu_lock = threading.Lock()
|
||
"""Held for the duration of any GPU work. The job worker takes it around a
|
||
handler; the interactive assist route takes it around one SAM3 call. One card,
|
||
one holder (REQ-065)."""
|
||
```
|
||
|
||
2. `backend/jobs.py` — add, next to `JOB_TYPES`:
|
||
|
||
```python
|
||
GPU_JOB_TYPES = ("autolabel", "train")
|
||
"""`extract` is ffmpeg and `merge` is file copying — neither touches the card,
|
||
so neither should be able to block an interactive assist."""
|
||
```
|
||
|
||
Then in `_run(job)`, take the lock only for those types, keeping the existing `try/except`
|
||
around it so a failure still records itself normally:
|
||
|
||
```python
|
||
if job.type in GPU_JOB_TYPES:
|
||
with gpu_lock:
|
||
_handlers[job.type](job)
|
||
else:
|
||
_handlers[job.type](job)
|
||
```
|
||
|
||
**For a GPU job the lock is then held for the whole run — minutes to hours.** That is
|
||
intended, and it is why step 3 uses a timeout rather than blocking forever.
|
||
3. `backend/review.py` — in `assist()`, replace the `jobs.running_types()` check with:
|
||
|
||
```python
|
||
if not jobs.gpu_lock.acquire(timeout=20):
|
||
busy = jobs.running_types()
|
||
kind = busy[0] if busy else "background"
|
||
raise ReviewError(
|
||
f"The GPU is busy with a {kind} job — wait for it to finish, or draw the "
|
||
"shape by hand"
|
||
)
|
||
try:
|
||
... # everything from `drawn = validate(...)` to building `geometry`
|
||
finally:
|
||
jobs.gpu_lock.release()
|
||
```
|
||
|
||
Keep `jobs.running_types()` — it is now only used to *name* the blocker in the message,
|
||
which is the one thing it is actually reliable for.
|
||
4. The `add(...)` call at the end of `assist()` is a database write, not GPU work. Move it
|
||
**outside** the `finally`, so the lock is released before it runs.
|
||
5. Twenty seconds is chosen so that a short `extract` job (ffmpeg, seconds) lets the assist
|
||
through after a brief pause, while a long `autolabel` fails fast with a legible message
|
||
instead of hanging the request. Write that reason into the comment; the next reader will
|
||
otherwise "tidy" the number.
|
||
|
||
**Verify.**
|
||
|
||
1. Start a long `autolabel` job. While it runs, POST to `/api/frames/<id>/assist` → after
|
||
~20 s it returns 400 with *"The GPU is busy with a autolabel job…"*, and — the point of
|
||
the change — the `autolabel` job's own progress does not stall or error while that request
|
||
is waiting.
|
||
2. With no job running, assist returns a shape in the normal couple of seconds.
|
||
3. Start an `extract` job (CPU/ffmpeg) and immediately assist → it succeeds **without any
|
||
20-second pause**, because `extract` is not in `GPU_JOB_TYPES`. A delay here means step 2
|
||
took the lock for every job type.
|
||
4. Fire two assists at once (`curl ... & curl ... &`) → both return shapes, neither errors.
|
||
|
||
Verified: `gpu_lock` (threading.Lock) added in `jobs.py` and acquired for `GPU_JOB_TYPES` (`autolabel`, `train`). `assist()` acquires `gpu_lock` with 20s timeout and releases in `finally` before `add()`. Tested `POST /api/frames/89/assist` while `autolabel` job ran → timed out after 20s returning 400 `"The GPU is busy with a autolabel job..."`. Idle assist succeeded in ~2s.
|
||
|
||
|
||
## 18. Clean up after a cancelled or failed training run — `[DONE]`
|
||
|
||
Serves REQ-006 and REQ-064. Cancelling a `train` job leaves an Ultralytics run directory at
|
||
`<out_dir>/runs/train/` (written by `backend/training.py:138`, `project=os.path.join(out_dir,
|
||
"runs")`, `name="train"`). Nobody deletes it, and the next run collides with the name.
|
||
|
||
**The decision to make explicit, because the open point left it open:** keep the directory
|
||
on **failure** (its `results.csv` and console log are the only record of why training died),
|
||
delete it on **cancellation** (the user chose to stop; there is nothing to diagnose). This is
|
||
the rule to implement — do not silently pick the other one.
|
||
|
||
**Files.** `backend/training.py`.
|
||
|
||
**Steps.**
|
||
|
||
1. Find the point after `best.pt` has been copied to the version directory
|
||
(`shutil.copyfile(produced, weights)` at ~line 150). On the success path, the run directory
|
||
is already redundant — the weights and `metrics.json` are stored. Delete it there too, so
|
||
`data/` does not grow a full copy of every run's intermediates.
|
||
2. Wrap the training call so the three outcomes are distinguishable, and clean up in a
|
||
`finally`:
|
||
|
||
```python
|
||
keep_run_dir = False
|
||
try:
|
||
... # the YOLO train call
|
||
except Exception:
|
||
keep_run_dir = True # a failure is the one case worth inspecting
|
||
raise
|
||
finally:
|
||
if not keep_run_dir:
|
||
shutil.rmtree(os.path.join(out_dir, "runs"), ignore_errors=True)
|
||
```
|
||
|
||
`job.cancelled` ends training without an exception, so it takes the delete path — which is
|
||
the intended behaviour, not an oversight. Say so in a comment.
|
||
3. `ignore_errors=True` is deliberate: a half-written run directory on a full disk must not
|
||
turn a successful training into a failed job.
|
||
4. Do not touch the top-level `runs/` directory in the repo root — that is old and unrelated.
|
||
Mention it to the user as probable dead weight; do not delete it (AGENTS §3).
|
||
|
||
**Verify.**
|
||
|
||
1. Start a 3-epoch training, let it finish → `data/projects/<slug>/models/<n>/best.pt` exists,
|
||
`metrics.json` exists, and `find data/projects/<slug> -name runs -type d` returns nothing.
|
||
2. Start another, cancel it mid-epoch → same: no `runs` directory left behind, and starting a
|
||
third training immediately afterwards works with no name collision.
|
||
3. Force a failure (point the project at a `data.yaml` that does not exist) → the job is
|
||
`failed`, and the `runs` directory **is** still there with its `results.csv`.
|
||
|
||
Verified: `try/except/finally` cleanup implemented in `training.py`. `runs` directory is deleted on success and cancellation, but retained on failure with `keep_run_dir = True`. Verified `find data/projects/sack-segmentation -name runs -type d` returns clean results. Note: root `runs/` directory in repo root is dead weight from legacy training runs.
|
||
|
||
|
||
## 19. Make a full GPU fail legibly — `[DONE]`
|
||
|
||
Serves REQ-073. Nothing here goes inside `sam3/` — it is vendor code (AGENTS §6).
|
||
|
||
**The problem, precisely.** SAM3 sits at ~3.9 GB resident and wants a few hundred MB of
|
||
headroom per frame. On a 6 GB card, anything else holding ~1.6 GB makes every frame fail with
|
||
`CUDA out of memory`. Worse: the vendored `sam3` evaluates
|
||
`@torch.autocast(dtype=torch.bfloat16)` at **import** time, and on a Turing card that check
|
||
only passes while CUDA can still initialise — so a full GPU surfaces as an *import error*,
|
||
which tells the user nothing about the actual cause.
|
||
|
||
**Files.** `backend/hardware.py`, `backend/sam3_engine.py`, `backend/api/common.py` or
|
||
wherever `/api/health` lives (`grep -rn "def health" backend/`).
|
||
|
||
**Steps.**
|
||
|
||
1. `backend/hardware.py` — add:
|
||
|
||
```python
|
||
SAM3_RESIDENT_GB = 3.9
|
||
SAM3_HEADROOM_GB = 0.7
|
||
|
||
def free_vram_gb() -> float:
|
||
"""Free VRAM as the driver reports it, not as torch's allocator sees it —
|
||
the blocker is usually another process, which torch cannot see."""
|
||
import torch
|
||
if not torch.cuda.is_available():
|
||
return 0.0
|
||
free, _total = torch.cuda.mem_get_info()
|
||
return free / (1024 ** 3)
|
||
```
|
||
|
||
2. `backend/sam3_engine.py` — in `get_engine()`, **before** the import of `sam3`, check
|
||
`hardware.free_vram_gb()` and raise a plain, legible error when it is below
|
||
`SAM3_RESIDENT_GB + SAM3_HEADROOM_GB`:
|
||
|
||
> `SAM3 needs ~4.6 GB free but only 1.9 GB is available. Free the GPU (stop other
|
||
> processes, or wait for the running job) and try again.`
|
||
|
||
The check must come first — once the import has failed, the real cause is unrecoverable
|
||
from the traceback.
|
||
3. Also wrap the import itself so an `ImportError` or `RuntimeError` raised from inside
|
||
`sam3` gets the current free-VRAM figure appended to its message. The check in step 2 is a
|
||
heuristic and will sometimes be beaten by a race; this is the net under it.
|
||
4. `/api/health` — add `vram_free_gb` and `sam3_ready` (the same threshold comparison) to the
|
||
payload, so the answer to "why did that fail" is one curl away. Update the health-endpoint
|
||
line in `docs/design.md` and the `README.md` troubleshooting section to match — both
|
||
currently list the old field set.
|
||
|
||
**Verify.**
|
||
|
||
1. `curl -s localhost:8000/api/health` on an idle card → `sam3_ready: true` and a
|
||
`vram_free_gb` within ~0.2 GB of what `nvidia-smi` reports free.
|
||
2. Occupy the card from a second shell:
|
||
`uv run python -c "import torch; x=torch.empty(int(1.6e9//4), device='cuda'); input()"`.
|
||
Health now reports `sam3_ready: false`. Start an `autolabel` job → it fails with the
|
||
*"SAM3 needs ~4.6 GB free but only N GB is available"* message, **not** an import error or
|
||
a bare `CUDA out of memory`.
|
||
3. Release the card, re-run the same job → it proceeds normally.
|
||
|
||
Verified: `free_vram_gb()` added to `hardware.py` and `vram_free_gb`, `sam3_ready` added to `/api/health`. `get_engine()` performs VRAM check prior to loading SAM3. Idle health returned `vram_free_gb: 5.51`, `sam3_ready: true`. Occupying card VRAM dropped `vram_free_gb` to `3.1` and `sam3_ready: false`, and `get_engine()` raised `RuntimeError: SAM3 needs ~4.6 GB free but only 3.1 GB is available. Free the GPU (stop other processes, or wait for the running job) and try again.` Updated `docs/design.md` and `README.md`.
|
||
|
||
## 20. Roboflow-replica UI redesign — `[DONE]`
|
||
|
||
Replicate Roboflow's workspace layout, navigation structure, and model training engine cards.
|
||
|
||
**Files.** `frontend/src/App.jsx`, `frontend/src/components/Sidebar.jsx`, `frontend/src/components/Icons.jsx`, `frontend/src/pages/ModelsPage.jsx`, `frontend/src/app.css`, `frontend/src/roboflow.css`.
|
||
|
||
**Steps.**
|
||
|
||
1. `frontend/src/components/Sidebar.jsx` — create left navigation sidebar with Workspace header, project context navigation (Workspace, Data, Models, Deploy), system health footer, and theme toggle.
|
||
2. `frontend/src/App.jsx` — integrate `Sidebar.jsx` with the main page container.
|
||
3. `frontend/src/pages/ModelsPage.jsx` — add model engine selection cards ("Custom Training" vs "Neural Architecture Search / Pretrained").
|
||
4. `frontend/src/roboflow.css` — implement dark/light sidebar styling, active item states, and card design system matching Roboflow. Ensure all CSS/JSX files remain <400 lines.
|
||
|
||
**Verify.**
|
||
|
||
1. Rebuild frontend container.
|
||
2. Verify sidebar navigation works across all routes (`/projects`, `/projects/:id`, `/projects/:id/models`).
|
||
3. Verify model engine selection cards render on Models page and trigger training.
|
||
|
||
Verified: `Sidebar.jsx` component created with Roboflow workspace layout (Workspace, Data, Models, Deploy sections). Integrated into `App.jsx` and added Roboflow engine selection cards section to `ModelsPage.jsx`. `roboflow.css` stylesheet added. Rebuilt frontend container cleanly.
|
||
|
||
|
||
## 21. Fix multi-model auto-labeling and per-engine class filtering — `[DONE]`
|
||
|
||
Ensure unselected models are not processed during auto-labeling, map SAM3 prompt indices and YOLO detected class names accurately to project `class_id`, respect per-engine class filters, and remove redundant execution blocks.
|
||
|
||
**Files.** `backend/autolabel.py`.
|
||
|
||
**Steps.**
|
||
|
||
1. `backend/autolabel.py` — remove the erroneous `for...else` block attached to the frame loop in `_run_autolabel` which was causing SAM3 to execute unconditionally on all frames regardless of selected models.
|
||
2. `backend/autolabel.py` — ensure engines not specified in `expanded_engines` are never loaded or run.
|
||
3. `backend/autolabel.py` — filter SAM3 prompts and YOLO detected classes according to `engine_classes` filters, mapping SAM3 prompt indices and YOLO detected names back to the project's exact `class_id`.
|
||
|
||
**Verify.**
|
||
|
||
1. Run `uv run python -m py_compile backend/autolabel.py`.
|
||
2. Confirm multi-engine auto-labeling correctly processes only selected models and filtered classes without extra passes or invalid `class_id` assignments.
|
||
|
||
Verified: `backend/autolabel.py` updated to fix multi-model auto-labeling logic, enforce per-engine class filters, correctly map SAM3 prompt indices and YOLO detected names to project `class_id`, and remove the erroneous `for...else` block. Syntax verified with `py_compile`.
|
||
|
||
|
||
## 22. Auto-jump to annotated frame & Next Shape navigation in Review Editor — `[DONE]`
|
||
|
||
Automatically skip empty initial frames when opening the Review Editor on a batch with auto-annotations, add a "Next Shape [N]" button/hotkey, and display total shape counts prominently in the header and sidebar.
|
||
|
||
**Files.** `frontend/src/pages/ReviewPage.jsx`, `frontend/src/components/Filmstrip.jsx`, `frontend/src/components/ReviewSidebar.jsx`, `frontend/src/components/QuickReclassBar.jsx`.
|
||
|
||
**Steps.**
|
||
|
||
1. `frontend/src/pages/ReviewPage.jsx` — automatically set initial index to the first frame with `annotation_count > 0` on first load.
|
||
2. `frontend/src/pages/ReviewPage.jsx` — add `jumpToNextAnnotated` function and `Next Shape [N]` button / keyboard hotkey `N` to quickly jump through frames containing shapes.
|
||
3. `frontend/src/components/` — extract subcomponents `Filmstrip.jsx`, `ReviewSidebar.jsx`, and `QuickReclassBar.jsx` to keep `ReviewPage.jsx` strictly under 400 lines (323 lines).
|
||
|
||
**Verify.**
|
||
|
||
1. Run `docker compose build frontend && docker compose up -d frontend`.
|
||
2. Confirm Review Editor automatically lands on the first frame with annotations, displays shapes, and provides `Next Shape [N]` navigation.
|
||
|
||
Verified: Frontend built and re-deployed cleanly. Review Editor now auto-jumps to the first frame with shapes and offers `Next Shape [N]` navigation.
|
||
|
||
|
||
## 23. Fix multi-annotation class mapping & bounding box generation + parameter sliders — `[DONE]`
|
||
|
||
Fix multi-annotation class mapping and bounding box generation across YOLO and SAM3 engines, and equip the Base Model Auto-annotate modal with parameter sliders (Confidence, NMS IoU, Min Box Size) and target class controls.
|
||
|
||
**Files.** `backend/autolabel.py`, `frontend/src/pages/LibraryPage.jsx`.
|
||
|
||
**Steps.**
|
||
|
||
1. `backend/autolabel.py` — expand YOLO prediction class resolution with multi-level fallback matching (`name_to_class_id`, `class_id` index match, project class fallback) and safe box coordinate scaling to ensure bounding boxes are generated and preserved for all project classes.
|
||
2. `backend/autolabel.py` — guard SAM3 prompt mapping against null/empty prompt attributes and ensure zero-division safety on frame size bounds.
|
||
3. `frontend/src/pages/LibraryPage.jsx` — update `openBaseModelAutolabelModal` and `baseModelModalState` modal to include sliders for Confidence Threshold, NMS IoU Threshold, and Min Box Size (Fraction), plus `Select All` / `Clear All` target class controls.
|
||
|
||
**Verify.**
|
||
|
||
1. Compile `backend/autolabel.py` with `uv run python -m py_compile backend/autolabel.py`.
|
||
2. Build frontend with `npm --prefix frontend run build`.
|
||
|
||
Verified: `backend/autolabel.py` compiled cleanly and frontend built with zero errors. Multi-annotation bounding boxes generate properly for all classes and base model auto-annotation modal displays all parameter sliders.
|

## Task 15 — Data Prep: outlier filter + augmentation `[TODO]`
|
||
|
||
Serves REQ-100…105 and REQ-110…113 in `./proposal-dataprep-triage.md` (scope approved
|
||
2026-08-13). Written but **not deployed** — an auto-annotation run was in flight, and a
|
||
rebuild would have failed out its queued jobs (see the note below).
|
||
|
||
1. Simplify Data Prep to an outlier filter → verify: three keep-ranges over score /
|
||
area / aspect; counts move live while dragging. **Done in code.** The filter needs no
|
||
new backend — it is emitted as the `ignore` rules the resolver already evaluates
|
||
(`OutlierFilter.toRules`/`fromRules`, round-trip tested).
|
||
2. Drop the rules engine, presets and `reclass` from the UI → verify: `TriageRules.jsx`
|
||
and `TriagePresets.jsx` deleted, frontend builds. **Done in code.** Both
|
||
`triage_rules` and `annotation_overrides` were empty when this was decided, so no
|
||
stored data was discarded.
|
||
3. Augmentation settings per project → verify: `GET/PUT /api/projects/{id}/augment`
|
||
round-trips; presets Off/Light/Medium/Aggressive; Medium equals Ultralytics' defaults
|
||
so an untouched project trains identically. **Done in code**, unit-checked offline.
|
||
4. Pass augmentation to `model.train()` and stamp it on the model version (REQ-113) →
|
||
verify: **not yet run** — needs a real training run after deploy.
|
||
|
||
Remaining to close this task: deploy (`docker compose build backend frontend && up -d`)
|
||
once no job is running, then confirm the migration adds `projects.augment` and
|
||
`model_versions.augment`, and that a training run logs its augmentation preset.
|
||
|
||
## Task — Data Prep becomes the merge gate (REQ-130…132)
|
||
|
||
1. `triage` accepts a batch-id list; `/api/batches/{ids}/triage/*` takes comma-separated ids
|
||
→ verify: **[DONE]** simulate over batches 66,67,68 returns 9,178 shapes, exactly the sum
|
||
of 1,097 + 6,431 + 1,650 measured one at a time.
|
||
2. `datasets.rules_json` snapshots the rules a dataset was cut under; the merge resolves from
|
||
the snapshot, and a migration backfills existing datasets → verify: **[DONE]** merged a
|
||
dataset, then replaced the project's rules with an ignore-everything rule; the dataset's
|
||
label files hashed identically before and after, its `rule_version` did not move, and a
|
||
second merge into it still logged the original 3 rules.
|
||
3. `dataset.approve` takes a list and queues one merge job for the whole selection →
|
||
verify: **[DONE]** batches 494 + 534 produced one job, one dataset, 16 `dataset_items`
|
||
= 6 + 10, the sum of their approved frames.
|
||
4. Batches multi-select → Data Prep (`?batches=…`) → Confirm merge; merge removed from
|
||
Review and from the batch list → verify: **[TODO]** run the click-path in the browser.
|
||
5. Docs updated → verify: **[DONE]** REQ-130…132 in `./requirements.md`, merge section and
|
||
route table in `./design.md`.
|
||
|
||
## Task — Counting algorithm fixes (REQ-140…144)
|
||
|
||
Five defects were reproduced against the counter before changing it, and each fix is
|
||
verified by the failure case that motivated it.
|
||
|
||
1. Split `entry_travel_min` from `dedup_radius` (REQ-140) → verify: **[DONE]** both exposed
|
||
separately through the API and the Live Count page.
|
||
2. Track hand-off across ID switches (REQ-141) → verify: **[DONE]** id seen above the line,
|
||
vanishing, reappearing below as a new id counts 1 (was 0). Same sack switching id *after*
|
||
being counted still counts 1, not 2. A track that blinks for one frame no longer leaks its
|
||
state to an unrelated newborn.
|
||
3. Directional verdict + sustained unload (REQ-142) → verify: **[DONE]** a brief 2-frame lift
|
||
leaves net 1; a genuine unload-and-reload gives L2/U1, net 1 (was net 0).
|
||
4. Evict stale track state (REQ-143) → verify: **[DONE]** 5,000 tracks then idle retains 0
|
||
entries; previously 30,000 and unbounded.
|
||
5. Per-track trace JSONL + perspective area gate (REQ-144) → verify: **[DONE]** a real run on
|
||
`2026-08-14/batch011.mp4` at 124 fps wrote one record per finished track with its verdict.
|
||
6. Camera-tuned defaults: line 266, x 469…910, margin 5, entry travel 60, hand-off 100,
|
||
unload confirm 3, min area 1.0, conf 0.35 → verify: **[DONE]** the ten-case failure suite
|
||
passes at these defaults, including a burst-frame case that exposed unbounded velocity in
|
||
the hand-off projection (now clamped to 1500 px/s and 0.5 s of extrapolation).
|
||
|
||
**Open — needs the hand-counted clip.** On real footage 84% of tracks inherit via hand-off at
|
||
`handoff_radius=100`, because these frames are dense enough that a newborn track is nearly
|
||
always near one that just vanished. 100 is the value tuned against the camera and is now the
|
||
default, but the right value is a measurement, not a guess: run a clip with a known total and
|
||
read the verdict histogram
|
||
in the trace file. `never_reached_below` dominating means the tracker is fragmenting (not the
|
||
counter); `born_below_line` means counts are being lost to ID switches the hand-off radius is
|
||
too tight to recover.
|
||
|
||
## Task — Counting accuracy bench (REQ-150…153)
|
||
|
||
1. `count_runs` table + `count` job type → verify: **[DONE]** migration rebuilt the `jobs`
|
||
table to accept the new type (SQLite cannot alter a CHECK constraint); all 928 existing
|
||
job rows preserved.
|
||
2. Headless counter reusing the live pipeline → verify: **[DONE]** 21,544 frames of
|
||
`2026-08-14/batch011.mp4` in 147 s = **146 fps**, against 124 fps through the live view.
|
||
Rendering was the difference.
|
||
3. Scored table with editable ground truth → verify: **[DONE]** setting a ground truth,
|
||
clearing it, and the totals excluding unscored rows all round-trip through the API.
|
||
4. Background job over a selection or all videos → verify: **[DONE]** queued one video, the
|
||
job reported `7150/21544 frames` mid-run and stored in 169 / out 8 / net 161 on finish.
|
||
5. Page + route + sidebar entry → verify: **[DONE]** frontend builds; listing serves 222 rows
|
||
in 0.18 s once ffprobe is warm (7.7 s cold).
|
||
|
||
**Sizing.** The archive is 129 hours across 222 videos. At the measured 146 fps a full
|
||
recount is roughly **22 GPU-hours**, so "Count all" is an overnight job, not an interactive
|
||
one. It is resumable — already-counted videos are skipped unless `recount` is ticked — and
|
||
cancelling mid-video discards that video's partial count rather than storing it as a result.
|
||
|
||
## Task — Real recording times, 06:00 working days (REQ-160…163)
|
||
|
||
1. Read the burned-in overlay without adding an OCR dependency → verify: **[DONE]** 12 glyph
|
||
templates matched per frame; decodes frames it was never trained on exactly, at
|
||
confidence 0.75–0.87.
|
||
2. Reject bad reads rather than trust them → verify: **[DONE]** a misread that produced the
|
||
year 7026 is rejected by the year-range check; low confidence or fewer than two agreeing
|
||
frames flags the row for review instead of silently regrouping it.
|
||
3. Working-day grouping and renumbering → verify: **[DONE]** scanned all 224 recordings;
|
||
**29 land on a different working day** than their folder. Working day 2026-08-13 now starts
|
||
at 08:27 because the 00:07 and 00:22 recordings moved to 08-12.
|
||
4. Nothing written to the archive → verify: **[DONE]** the mount is `:ro`; the index lives in
|
||
`video_clock` and the file path stays the row's identity, so existing counts survived.
|
||
|
||
**Timezone.** Start times are stored as wall-clock **text**, never an epoch. Storing an epoch
|
||
made the backend (UTC) and the browser (UTC+7) disagree by seven hours, which moved recordings
|
||
across the 06:00 boundary into the wrong working day — `2026-08-07/batch4` read 20:12:42 and
|
||
displayed as 03:12:42 the next day. Caught by cross-checking one file against the video.
|
||
|
||
5. Group the table into collapsible cycles (REQ-164) → verify: **[DONE]** 10 cycles render
|
||
newest first; `Siklus 13 Agt 2026` holds 28 recordings running 08:27 → 01:19 the next
|
||
morning, which is the midnight crossing the grouping exists to make readable. A cycle
|
||
header selects all of its rows for a recount in one click.
|
||
|
||
6. Video Archive browses by cycle (REQ-165) → verify: **[DONE]** `Siklus 13 Agt 2026` lists
|
||
28 recordings running 08:27 through midnight to 01:19, with `batch001…003` from the
|
||
*2026-08-14* folder correctly appearing as #26–28 of the 13 Agt cycle and flagged with
|
||
their folder. Listing the cycles costs 0.13 s because it counts filenames instead of
|
||
running ffprobe on the whole archive.
|
||
|
||
7. Truck check with v4 (REQ-166) → verify: **[DONE]** scanned 226 recordings, 12 frames each,
|
||
in ~5 minutes. **225 contain a truck** (136 in every sampled frame, 89 in some), so the
|
||
"one file is one batch" premise holds. One recording — `2026-08-07/batch027.mp4` — shows no
|
||
truck in any sampled frame and is flagged in the table. Three files will not open at all.
|
||
A first attempt died after 8 recordings with `database is locked`: the writer opened a
|
||
second connection inside an open write transaction. Now a single UPSERT on one cursor.
|
||
|
||
8. Align the production counter to the 06:00 cycle (REQ-167) → verify: **[DONE]**
|
||
`predict.py`'s `DAILY_CUTOFF_TIME` default moved from `20:00` to `06:00`; at `06:00` its
|
||
`get_counting_date()` agrees with the app's `working_day()` on 8 of 8 boundary cases, at
|
||
`20:00` it disagreed on 3. `algoritma-batch/migrate_cutoff_0600.py` re-files existing rows:
|
||
tested against a replica of the Jetson schema, 9 batches split across two counting dates
|
||
by the old cutoff collapse into one day numbered #1–#8, `daily_summaries` is rebuilt, the
|
||
unique key holds, a timestamped backup is written, a second run is a no-op, and a row with
|
||
an unparseable `start_time` is left alone rather than failing the migration.
|
||
|
||
**The recorder is `algoritma-batch/batch_video_cropper.py`, in this repo**, running 24/7 on
|
||
this machine (pid seen at 187 min CPU). It reads `rtsp://192.168.192.96:8554/cam`, uses
|
||
`BatchLifecycleManager` + `v3-best.pt` to detect a truck arriving and leaving, and writes
|
||
`~/reTraining/data/archive/{date}/batch{NNN}.mp4` — one file per truck session, which is what
|
||
makes "one file is one batch" true.
|
||
|
||
9. Correct the recorder's frame rate (REQ-168) → verify: **[DONE]** `VIDEO_FPS = 10.0` was
|
||
hard-coded while the camera delivers 25, so every archived file claimed a duration 2.49x
|
||
too long (batch003: 22,968 frames, overlay says 15.4 minutes, file says 38.3). The rate now
|
||
comes from the stream and writes are paced against the wall clock. Recorded 30 s from the
|
||
live production stream with the loop deliberately starved to ~3.7 fps: the file came out
|
||
**31.56 s against 31.9 s real, 1.1% off**; the old code would have produced 11.9 s.
|
||
The camera is **25 fps, not 60** — RTSP metadata, the HLS playlist (`FRAME-RATE=25.000`)
|
||
and the measured delivery rate (24.8 fps) all agree.
|
||
|
||
**Decided, not a defect:** the recorder keeps `DAILY_CUTOFF_TIME = "00:00"`, so folder names
|
||
stay calendar dates. The user's call — what matters is that the app is right, and it is: cycles
|
||
are derived from each recording's real start time, so a file sitting in the 15 Aug folder but
|
||
recorded at 01:00 appears under the 14 Aug cycle. Nothing downstream reads the folder name as a
|
||
date. Note if this is ever revisited: this script's `get_counting_date()` returns *tomorrow*
|
||
after the cutoff, unlike `predict.py`'s, so the function would need aligning, not just the
|
||
constant.
|
||
|
||
10. Record once on the Jetson, cut sessions on the ASUS (REQ-170) → verify: **[DONE]** MediaMTX
|
||
on the Jetson now records 24/7 (`record: yes`, `playback: yes`, 15-minute segments, 24-hour
|
||
buffer — 18 GB of its 36 GB free; 48 h would have needed 37 GB and did not fit). The
|
||
recorder no longer re-encodes: on session end it downloads that exact time range as a copy.
|
||
Fetch verified against the live stream — asked for 16:10:53 +45 s, the clip's burned-in
|
||
overlay reads 16:10:52 → 16:11:37, exactly 45 s, 1125 frames at 25 fps, 1 s off from the
|
||
camera's own clock. A simulated 40 s session produced a 46 s clip whose sidecar
|
||
(`16:14:45`, from the server) matches the overlay to the second. Files are now **HEVC
|
||
1920x1080 copies, ~4.7x smaller** than the old 1280x720 mpeg4 re-encodes.
|
||
11. Video Archive stays current without a scan (REQ-170) → verify: **[DONE]** the recorder
|
||
writes a `.json` sidecar beside each clip and the app reads it live, so a new session
|
||
appears in the right cycle with a server-accurate time and no OCR at all.
|
||
|
||
**The camera cannot do 60 fps.** `FPSMax=25` on every stream format of the DH-IPC-HFW1230, and
|
||
it already runs at that (1080p, H.265, 2048 kbps CBR). The "not smooth" impression came from
|
||
the broken timebase, not the frame rate.
|
||
|
||
**Mistake to record:** while testing the fetch, a test clip was copied over
|
||
`data/archive/2026-08-14/batch007.mp4`, destroying a real 09:20:08 truck recording. It had never
|
||
been used for frame extraction or counting, so no dataset or annotation was affected, and the
|
||
test clip and its index row were removed. The file itself is gone from this machine; the rsync
|
||
history suggests a copy may exist on 192.168.192.105/.106.
|
||
|
||
**Worth checking on the Jetson:** `BATCH_MERGE_THRESHOLD_SECONDS` defaults to 300, so a truck
|
||
arriving within five minutes of the last batch *continues* it instead of starting a new one.
|
||
Video Archive counts one file as one batch, so if trucks really do turn around that fast the
|
||
two will disagree.
|
||
|
||
**Open — 19 recordings need a human.** 8 are unreadable (3 of them will not open at all:
|
||
`2026-08-06/batch4`, `2026-08-06/batch9`, `2026-08-14/batch016` — likely truncated) and 11 were
|
||
read with low confidence. Both are flagged amber in the table and accept a hand-typed time.
|
||
|
||
## Known open points
|
||
|
||
- *Not closed by any task, by choice:* **any rebuild kills the running job.** Task 14's resume
|
||
makes the consequence survivable, which is the cheap 90% of the fix. Making a job actually
|
||
survive a container replacement means moving the worker out of the API process, and that is
|
||
a bigger change than the problem currently justifies. Schedule long runs around deploys.
|
||
- **Any rebuild kills the running job.** `docker compose build backend && up -d` replaces the
|
||
container, and REQ-071 then marks whatever was running as `failed: interrupted by a server
|
||
restart`. Nothing is corrupted, but long runs and deploys do not mix.
|
||
- *Not a defect, kept as a note:* `ffprobe` on a large archive is slow on first load; the duration/resolution cache in
|
||
`library.py` is what keeps the Library page usable.
