Stage 1 state

Task: docs/stage1-training-task.md. Settings and weights: train/README.md. Updated 2026-10-03 22:40.

Done

• Step 0 (setup): train/.venv (Python 3.11.17, uv), mlx-lm 0.32.0 / mlx 0.32.3. Model mlx-community/Qwen3.8-27B-4bit at ~/models/Qwen3.8-27B-4bit (affine 4 bit, group 64, 16.1 GB; base Qwen/Qwen3.8-27B). The Ollama NVFP4 weights do not load in mlx_lm (global scale).

• Server: train/serve.sh (mlx_lm.server, port 8080, thinking on with reasoning_effort medium, temperature 0.2, top_p 0.95, top_k 20, min_p 0, max tokens 32768). Tool-call test passed.

• Eval subset (Kral decision): train/subset.json (copy runs/stage1/subset.json), 25 tasks. The task document says "all accepted tasks" for step 2; Kral changed it to this subset. Use the same list after training.

• Runner: train/baseline.py --label <label> (one task at a time, results runs/stage1/<label>.json, run directories runs/stage1/<label>/).

• Step 1 done (2026-10-03 22:20, Kral decisions applied, strict dedup rule): train/prepare.py, report train/data/report.md. Corpus: SAP-samples/abap-cheat-sheets (Apache-2.0), 370 records, 2.81M real tokens. Version dedup: main (ABAP Cloud) and the newest v* (Standard ABAP) always kept; each older v* is compared with the next newer v* and kept only if more than 5 % of lines differ. 335 object versions: 323 kept, 12 removed. Tokens 2,806,501 -> 2,658,082 after dedup. Documents over 16384 are split, not removed: 41 documents -> 82 pieces (classes at ENDMETHOD, markdown at "##"; 15 blocks needed a line cut); tokens after split 2,660,834; no piece over the limit. Token share: DOC 49.0 %, CLAS 46.9 %, other 4.2 %. Train 374 docs / 2.53M tokens, valid 20 docs / 135k tokens (split by family, seed 20261003). 748 iterations for 2 epochs (the count is the same as with the first dedup rule by coincidence). test.jsonl = copy of valid.

Running (detached)

• MLX server (restarted 2026-10-04 06:38 after it had exited; PID in pgrep -f mlx_lm), log runs/stage1/server.log.
• Baseline on the 11-task subset (train/subset.json), thinking off, loop guard 3, max_tokens 16384, started 2026-10-04 about 08:00 by train/baseline_chain.sh (run base 20400), logs runs/stage1/baseline_chain.log and runs/stage1/baseline.log. Notification after 2 tasks and at the end ("Baseline (11 tasks) ended").
• The T01 trial runs without the guard were stopped (_aborted_* in runs/stage1/baseline/, A4H objects deleted).

Next

0. After the baseline ends: Step 3 training test (20 iterations), Kral stops A4H first and the MLX server is stopped.

1. B2: read the last lines of runs/stage1/baseline.log; summary from runs/stage1/baseline.json (t01_test_budget40 holds the T01 test result). Commit.

2. Step 2, second part: valid loss of the base model (mlx_lm.lora --test, no adapter) after the baseline.

3. Step 2, second part: valid loss of the base model (mlx_lm.lora --test without adapter; check the options with --help first). Add it to runs/stage1/baseline.json.

4. Step 3 (training): Kral stops A4H; stop the MLX server; no other model loaded. Short test of 20 iterations first.

Notes

• The earlier T01 score 41.7 (run 103) used the Ollama NVFP4 weights. The baseline of 2026-10-03 (MLX 4 bit) is the new reference.
• Harness changes that matter for stage 1 runs: ADT activation fallback for PROG/FUNC (EPOD bug), G2 finds the FUNCTION statement after local classes, call budget floor 60, empty-turn retry in the agent (max_tokens only for cloud models; the MLX server limit is --max-tokens 32768).
• Session 2026-10-03 (evening): follow-ups of docs/devir-notlari.md section 3 done from stored results (review of 10 + 10 tasks, easy candidates, docs). No model run was started. Reruns wait in runs/stage1/rerun_queue.txt (G0119, G0162) until the baseline ends.
