00:59 · askedcan we move these data into ~/projects/ams-1080 with documentation for agents and human to understand the source and basic statistics?
01:00 · repliedYes. I'll make `~/projects/ams-1080` a self-contained data repo: the pulled exports, videos and manifest moved there, the chart pack fetched alongside, a puller and a stats script inside it, a README for people and a CLAUDE.md for agents, and a symlink left in new-knia so nothing here breaks.
01:02 · repliedDone. The data now lives at `~/projects/ams-1080/`, and the old path in new-knia is a symlink to it so nothing here breaks. **Layout** | path | what | |---|---| | README.md | for people: where the clips and labels came from, file map, status meanings, five caveats, quick start | | CLAUDE.md | for agents: what counts as truth, what not to do, where the data is used | | STATS.md | generated: status counts, coverage per field, project-vs-labeler agreement, branch table, all 72 chosen charts, per-project table for all 108, annotators, impact-frame distribution, video probe, goldset overlap | | clips.json | the manifest, 1,080 rows | | videos/ | 1,080 clips, 7.7 GB, 1080p at 15 fps | | export/ | the 108 raw Label Studio exports | | knia-car-pack.json | the wizard tree and chart pack the labeling ran on | | scripts/ | pull.py, stats.py, the labeling config, and notes on the rest of the instance | **Two things the docs flag that you should know.** The frame indices in the annotations are in the tool's 24 fps space while the videos are 15 fps, so impact time is frame divided by 24, not 15. I'd have got that wrong without the ffprobe check, so it's caveat 4 in the README and in the quick-start snippet. And the goldset overlap came out at 169 clips with cv-processing's 688 set, slightly more than the 162 I counted from inside Label Studio, because the local check matches on file stems rather than the API's task list. Both scripts run with plain `python3` and stdlib plus httpx. The token stays in `~/projects/conf`, read by pull.py and mentioned in the docs only by location. One suggestion: your global CLAUDE.md lists the project directories you work from. Adding a line for `ams-1080` as a data directory would let future sessions find it without going through memory. I didn't …
01:03 · askedadd ams-1080 to my global CLAUDE.md
01:03 · repliedAdded. The line sits in the directory list of your global CLAUDE.md, after the `md` entry: > `~/projects/ams-1080/` — data, not code: 1,080 dashcam clips with a labeler-chosen KNIA 도표, pulled from Label Studio. Read its README.md and CLAUDE.md before using; the project chart is a pre-sort key, not a label. Future sessions in any of your projects will see it, and the pointer to the repo's own docs keeps the details in one place.

01:05 · askedlook over this directory and understand the contents
01:05 · repliedI'll read the README, STATS, and the directory layout first.
01:05 · repliedThe docs are thorough. I'll now check the scripts, a sample clip row, and the export/pack shapes to confirm the docs match the data.
01:06 · repliedOne probe crashed on the six unannotated rows, which lack a status key. One more pass to check the box and timeline label vocab and the keyframe-per-box claim in the README.
01:06 · repliedI've read the docs, both scripts, the labeling config, the KNIA pack, a raw export, and probed the manifest. Here is what this directory is. **What it is.** A frozen data drop, not code. 1,080 AI Hub dashcam clips of 차대차 accidents, pulled from Ian's Label Studio on 2026-09-09. Each clip was annotated once by a Vietnamese-speaking labeler who walked the KNIA 도표 tree in a custom wizard, marked an impact frame on a timeline, and drew evidence boxes. **Layout.** - `clips.json` is the manifest, one row per clip, derived from `export/` by `scripts/pull.py`. Export wins on any disagreement. - `export/<project_id>.json` is the raw Label Studio export, 108 files of 10 tasks each. - `videos/` holds 1,080 mp4 files, 1920×1080 at 15 fps, 10 s each, 7.7 GB. - `knia-car-pack.json` is the crawled KNIA tree the wizard ran on: 108 chart leaves with base ratios, factors, descriptions. Personal-reference material, keep internal. - `projects.json`, `STATS.md`, `scripts/` (pull, stats, label config, instance notes) round it out. **The two chart columns are not interchangeable.** The project title is an AI Hub accident-type pre-sort; the labeler's choice is `chart_id`. They agree on 16 of 808 completed clips, and the disagreement is at branch level. Labeler picks also pile onto 차43-2 and 차12-1, a quarter of the total. Neither column is gold until someone spot checks. **Status split.** 737 completed_base, 71 completed_adjusted with a ratio, 266 not_observable, 6 never annotated. The unannotated six are five clips of project 차13-2 and one of 차47-2. **Things I verified that the README understates or omits.** - Frame space is the tool's 24 fps, not the video's 15 fps. Divide by 24 for seconds, as documented. - Timeline labels are a mixed vocabulary. Mostly Vietnamese aliases, but a handful …
01:10 · askedfirst, I want these videos to be servable (most ui can't do file://...) so this project will make the videos servable through a local server. i would also like to view its contents in the web ui (the labeled data and charts). these data should be accessible with api, and mcp so agents can use it. documentation for using the data. all cv, vlm, other projects will start using this data. use docker for local deployment (orbstack) and serve it under a port that doesn't collide with default ports. you can also use sqlite or other lightweight local datastore if needed.
01:11 · repliedUnderstood. Let me mirror back what I'm building before I start, since it's a fair amount of scaffolding. **What I understood:** this directory becomes the single serving layer for the 1,080 set. Every other project (cv-processing, new-knia VLM harnesses, future ones) stops reading `clips.json` and mp4 paths directly and instead talks to one local endpoint. That endpoint has to give browsers seekable video over HTTP, give humans a UI to look at the labels on top of the video, give scripts a REST API, and give agents an MCP server. Docker on OrbStack, one non-default port. **Decisions I'm making so I don't block:** - One container, one port: **41080**. FastAPI serves videos with Range support, the web UI, `/api/*`, and MCP over streamable HTTP at `/mcp`. - **SQLite as the query substrate**, built from `clips.json` plus the KNIA pack at startup. Derived and disposable. It also lets agents run read-only SQL, which is the most flexible affordance for "all projects will use this". - **Labels get normalised** at build time. The raw data mixes Vietnamese aliases, raw values, and Korean strings for the same thing. The API exposes canonical names and keeps the raw string. - **Frame extraction via ffmpeg** in the container, so a VLM project can ask for "the impact frame of clip X" as a JPEG through both REST and MCP. This is the most common op those projects will do. - The repo directory is mounted read-only. The server never writes into `export/` or `videos/`. Let me check the pieces I need before writing code.
01:14 · repliedI now have everything needed for the MCP layer: the 2.x SDK renamed FastMCP to MCPServer and mounts as a Starlette sub-app. Writing the server, the build step, the web UI, and the Docker files now.
01:20 · repliedAll the code is in place. Now I'll build the SQLite locally and check the counts, and import the app module to catch any import-time errors, in parallel.
01:24 · repliedStructured output now works for every tool and the client smoke test passes against the container. Next: rebuild the container with the annotation fix, open the UI in Chrome, and write the docs.
01:24 · repliedContainer rebuilt and healthy. Now I'll open the UI in Chrome: the clips list first, then a clip page to check the box overlay.
01:25 · repliedThumbnails were being served fine (17 requests, all 200), so they were just loading. Now screenshot the clip page, check console errors, then look at the chart and stats pages in one batch.
01:28 · repliedFileResponse handles all the range cases and the thumbnail 500 is fixed. Now reload the clip page and check whether Chrome plays the video and draws the overlay.
01:32 · repliedThe page's overlay interpolation matches the API to four decimals, the container-served list shows thumbnails with the A/B boxes drawn, and the console is clean. Closing my tab and wrapping up.
01:32 · repliedThe serving layer is built, running in OrbStack, and verified end to end. The container is up now at **http://localhost:41080**. **What's running.** One container, port 41080, this directory bind-mounted read-only. On start it builds a SQLite from `clips.json` and the KNIA pack in a fifth of a second, then serves four surfaces from one process: - **Web UI** at `/`. Clips list with filters (status, labeler chart, pre-sort chart, branch, agree, impact mark, A+B boxes, annotator), impact thumbnails with boxes drawn. Clip page with the video, a canvas overlay that interpolates the boxes live, click-to-seek timeline marks, frame stepping, wizard path in Korean and Vietnamese, chart base ratio, factor decisions and adjusted ratio. Chart pages with the KNIA text, factors, and the cross-tab of pre-sort versus labeler. Stats and Notes tabs. - **REST** at `/api`, OpenAPI at `/docs`. Clip list and detail, boxes interpolated at any time in percent, pixel and xyxy, JPEG frame at any time with boxes drawn, charts, stats, schema, and a guarded read-only SQL endpoint. - **Video** at `/videos/<name>.mp4` with Range support. Verified with curl, ffprobe over HTTP, and the browser's own fetch. - **MCP** at `/mcp`, streamable HTTP. Eleven tools including `frame_image`, which returns the JPEG as image content so a VLM agent can look at a clip. Register with: ``` claude mcp add --transport http ams1080 http://localhost:41080/mcp ``` **Docs and client.** `API.md` covers running it, the frame-space rules, every endpoint, the MCP tools, the SQLite schema with example queries, and the caveats pointer. `scripts/ams1080_client.py` is a zero-dependency Python client other projects can copy. README and CLAUDE.md now point to both. **Data decisions baked in.** Labels are normalised to the config'…
02:08 · askedregister the mcp server in claude code and try it
02:09 · repliedI'll register it at user scope so it's available from every project directory, not just this one, then verify Claude Code can connect and exercise a tool through a one-shot session.
02:09 · repliedThe MCP server is registered at user scope and works from Claude Code. **Registration.** Added as `ams1080` in your user config, so it's available from every project directory, not just this one. `claude mcp list` shows it connected. Remove with `claude mcp remove ams1080 -s user` if you ever want it gone. **Live test.** A fresh one-shot session was told to answer only through the MCP tools. It called four of them and came back correct on every point: - `dataset_notes` gave it the caveat that the pre-sort and the labeler agree on 16 of 808 clips, so neither is ground truth. - `sql` returned the status counts, matching STATS.md. - `boxes_at` returned the A and B boxes at the impact of the test clip, matching what the REST endpoint gave earlier. - `frame_image` returned the JPEG and the model described it as a dark sedan's rear bumper against the ego car's hood at the moment of a rear-end collision, with the B box blue and the A box teal. That is what the frame shows. So an agent that connects cold learns the caveats from the server's instructions, can query the data, and can look at a clip. This session predates the registration, so the tools are not loaded here. Any new `claude` session in any directory will have them.
06:47 · askedI want a quick outlet to mark some videos with data. The purpose is to notice front vs back dashcam, 3rd person vs accident relate party, night(too dark), low res(too blurry). This may be considered to find if some of the other services using the data can consider or export later in order replace the videos for better ones
06:48 · repliedLet me mirror this back first. You want a fast per-video tagging pass with four judgments: camera position (front or rear dashcam), viewpoint (recording car is a party to the accident or a bystander), too dark, too blurry. The tags are metadata alongside the labels, so downstream services can exclude or deprioritise those clips now and swap them for better footage later. **Design I'm going with:** - Tags live in a **separate writable SQLite** under `flags/` in this directory, never in the derived DB, so they survive rebuilds and re-pulls. Every write also dumps `flags/flags.json` so a service can read a flat file without talking to the server. A log table keeps history. - Generic key/value schema so new tags can be added later without migration. Values are constrained: camera front/rear, viewpoint party/third_party, dark yes/no, blurry yes/no, plus a free note. A `source` column separates human tags from agent tags, since a VLM pass for dark/blurry is an obvious follow-up. - **Review mode** in the UI: one clip at a time, looping video, single-key hotkeys, auto-saves on every keypress, arrow keys to move. Tags also show on the clip page and as filters and chips in the list. - REST and MCP get read and write endpoints, and a CSV export. Writing it now.
06:49 · repliedNow the UI: a shared flag widget with hotkeys, the review mode, and flag chips plus filters in the list.
06:50 · repliedBoth parse. Now rebuild the container with the writable flags mount and exercise the flags API end to end: set, read, filter, CSV, the JSON snapshot, and validation errors.
06:53 · repliedThe tagging outlet is live and the test flags are wiped, so you start from zero. **How to use it.** Open http://localhost:41080, filter the clip list however you like, and click "▶ review these N". One clip at a time, video looping, and every keypress saves immediately: | key | meaning | |---|---| | F / R | camera front / rear | | P / T | recording car is a party / third-party bystander | | D / B | too dark / too blurry | | K | looks fine (dark=no, blurry=no) | | X | clear all flags on this clip | | N | type a note | | → ← | next / previous clip | | U | jump to next unflagged clip | The same widget sits on every clip page. Pressing the same key again clears that value. The list shows flag chips per clip and has flag filters, including `unset` for "not reviewed yet". **Where the data goes.** A separate SQLite at `flags/flags.db` plus a flat `flags/flags.json` rewritten on every change, so a downstream job can read the file without the server. This is the only path the container writes, and it survives rebuilds and re-pulls. A log table keeps the history. `GET /api/flags.csv` exports it. **For other services.** The clip list endpoint accepts the flag filters, so a CV job can ask for `dark=unset&blurry=unset&viewpoint=party` and get the clean set. MCP gained `get_flags`, `set_flags` and `flags_summary`, with the same filters on `list_clips`. A `source` column keeps human tags apart from agent tags. I tested this with a one-shot Claude session: it looked at a frame, judged it not dark and not blurry, and wrote the flags under its own source name. That means a VLM pass over all 1,080 clips for dark and blurry is a cheap follow-up, and you'd be able to compare it against your own pass. **One design note.** `dark` and `blurry` are explicit yes/no, not just a "bad" flag, …

01:17 · askedwe are going to start using ~/projects/ams-1080 data. right now, its creating api, mcp, video serving server. but before its built just know that we will now deviate from using 688 clips. when testing, because we don't want to use the whole dataset evertime we run something (some test may require us to), just use a small subset of those data. Another important note on licensing. this is internal feasibility demo. the license worry has to stop. best performance is our goal. we will make a decision to use alternative or pay for the license if we have to. stop making choices because of the license. our first job is to make a gate for vehicle id persist with bytetrack and re-id with in mind we have some gate that blocks it. is that correct?
01:17 · repliedNoted on all three. I'll save those as standing rules, read the ams-1080 docs as its CLAUDE.md asks, then confirm the read.
01:17 · repliedDocs read. Saving the three standing rules to memory, then confirming the read.
01:18 · repliedYes, that's the read, with one sharpening. The first job is the **gate**: everything that must reject a detection before it can seed or steal a track ID. The gate is built knowing ByteTrack and ReID sit right behind it, so it only needs to answer one question per detection: is this a real vehicle on the road, or the hood, a reflection, a box pinned on the ego car, or a duplicate box on the same car. Tracking and ReID then own persistence. Three things the new rules change in the plan I gave earlier: - **Tracker comes off the shelf.** With licence off the table, Ultralytics YOLO11 plus its built-in BoT-SORT with ReID replaces the hand-written ByteTrack. That is ByteTrack association, a Kalman filter, camera-motion compensation and an appearance embedding in one config file. The offline tracklet-linking pass stays as our own addition, since no real-time tracker does it. - **Hood mask stays.** Mask2Former on Mapillary already finds the dashboard; the non-commercial note just stops mattering. The gate applies it at detection time rather than downstream. - **The subset.** Roughly a dozen clips from ams-1080 chosen for the failure modes: glossy dash, night, the other party filling the frame at contact, and a heavy-traffic clip. Fixed and named so runs compare. One useful thing in ams-1080 for this: annotators drew A and B boxes at a keyframe. Each of those boxes should land on exactly one persistent vehicle ID. That gives a cheap identity check on every completed clip without any new labelling. It is not gold, but it is a number. Three things I need from you before I start building: 1. **Is the read above right**, gate first, then tracker plus ReID behind it, offline linking as our own pass? 2. **In the first clip I opened, the Xe A box covers the bottom two thirds of th…
01:24 · asked1. i would like to know why the most lastest models are not selected i.e. yolo26. for the gate, i would like to see the hood solution works with masking. we could use segmentation or even monocular depth (Depth Pro) to find static parts that are close (hood). if we can mask it correctly even before it goes in to yolo or other detections it may help (the lights, lanes reflected off the hood)
01:24 · repliedTwo things to do: answer the model question with current facts rather than memory, and build a visible hood-mask comparison on a small ams-1080 subset. Checking the current model landscape and the local environment first.

02:23 · repliedThe tracking stage is built, ran over the subset, and its report is sent. Everything is staged in git, not committed. **What runs.** One command reads each clip's frozen detections file, applies a class-agnostic NMS, and drives Ultralytics BoT-SORT directly with those boxes plus the real frame, so camera-motion compensation and ReID crops see the picture while no detector runs. The ReID encoder is the yolo26x ReID ONNX model, downloaded on first use. ``` uv run python -m cv.track --subset subsets/gate-10.txt ``` **Config.** A `[track]` section holds every tracker parameter: thresholds, match and buffer settings, motion compensation method, ReID model and its two thresholds, the pre-tracking NMS, and the preview frame offsets. The lost-track buffer is given in seconds and converted to fed frames, since the tracker sees every second video frame. **Outputs per clip** under `work/track/<clip>/`: a tracks file with one tracklet per ID, its label, span and observations, plus a header naming the detections file version and the tracker config. The preview is four frames around the labelled impact time from ams-1080, boxes coloured by ID. **What the run says.** | across 10 clips | value | | - | - | | tracks | 196 | | tracks under 1 s | 99 (51%) | | median tracks per clip | 17.5 | | duplicate boxes merged by NMS | 70 of 4,239 | - **The other party holds its ID through contact.** On the glossy-dash clip the SUV is ID 8 from 1.4 s before impact to 1.5 s after. On the dense-traffic clip at 9 active IDs per frame, the van and the excavator truck keep their IDs across the impact. - **Fragmentation is still the main defect,** but it lives at the horizon. Short tracks have a median box height of 26 to 154 px and sit in the top half of the frame. They are far vehicles flickering, …

02:32 · askedthe cv project will have its own ui. but use ams-1080 api/mcp outlets. ui is for visualizing results at every stage. we won't be linking it to labeled data right now. just viewing the result is fine. so for now, we could have our own datastore (not for videos but for our detection, gate etc). we will have our own server up and running. make sure the port doesn't collide frequently with other services. for now, i want to view the gate, and the id with playable video. this is because we want a service on our own to see the results, load from saved computation, design the ui according to the task. not related to labeling or any other related projects. simply view our results.
02:32 · repliedBefore building, I'll check what the ams-1080 server already exposes for video so our viewer can use it, and which ports are in use around the tree.
02:35 · repliedThe server answers on port 41421 and the ams-1080 stream is reachable. Opening the viewer in Chrome to check it.

My proposals follow; reply with yes, or with the changes you want. 1) REGISTRY - `evals/lense_evals/registry.py` stays the entry point, with the same TASKS / METRICS / METHODS shapes and ensure_*. - At the bottom it merges `lense_evals.registry_<track>` modules, found by pkgutil glob of `registry_*.py`. Duplicate keys raise at import. A track then adds its own file and never edits yours. - If you'd rather have an explicit append-only list (TRACK_REGISTRIES = [...]), that's fine too. - Mine would be `evals/lense_evals/registry_vehicles.py`. - Scoring dispatch: score.py is hard-wired to impact_item/impact_metrics and to one label field. - Proposal: a METRICS entry may carry `"scorer": "lense_evals.scorers_vehicles"`, a module exposing: - `item(facts_by_field: dict[str, list[fact]], output, definition) -> dict` - `metrics(items, definition) -> rows` - With no scorer, the current impact path runs unchanged. - The conflict check applies per field listed in definition["label_fields"]. - Counterpart scoring needs two fields per clip: impact_time_s and the counterpart box. - Who edits score.py: you, or I send a small diff for you to review? 2) AMS-1080 BOX IMPORT (storage/import_labels_ams1080_boxes.py, your storage/ pattern) Measured on clips.json. A and B are chart roles, not ego and other. The hood strip is cv's `_ego_like`: first keyframe bottom ≥90% and width ≥55%. - 437 clips: A = hood strip, B = counterpart - 189 clips: B = hoo…
08:32 · repliedTrack E's proposals are mostly sound. The registry hook and the scorer dispatch sit in Track A's own files (`evals/`), so I'll implement both rather than review a diff from them. First, two data answers they need: how many ams-1080 originals in S3 aren't 1920×1080, which is their box-coordinate risk, and how many screening items are still open.

23:46 · repliedD28 (vehicles are named 고객차/상대차, never 의뢰차 or A/B) is applied to Track E's text, pushed as a326e0e. - **What I changed:** my STATUS section, my ARCHITECTURE sections and my P27 proposal no longer use the chart letters as vehicle names. They say "chart role letters (raw label values)" for the ams-1080 box labels, and "the recording vehicle" / "the counterpart" for the cars. I also reworded one code comment that named party terms. - **What didn't need changing:** Track E's stored outputs use content-neutral ids ("ego", "other_vehicle") and never carried party words. The labeler's letter stays as a verbatim label value, which D28 allows. - **Checks:** the new party-terms test and the decision-numbering test both pass, and the full suite passes (154). Track E had no Korean occurrences, so the ratchet baseline didn't move. - **Left alone:** two lines in Track A's section of STATUS still quote AI Hub's "1인칭 = B" rule and "ego role B", but that section isn't mine to edit.
