feat(gen): streaming + crash-resilient resume for full-scale data gen
...
The original gen_synthetic.py held all N samples in a [None]*n list and
only wrote at the end — three full-scale runs were killed mid-way (env
reaps long sessions) and lost everything (0 bytes on disk each time).
Fixes (proven on the 500k+100k run that just completed):
- run() now streams: each completed future is written to disk the instant
it's produced, via an O(workers) reorder buffer that keeps output in
index order. Peak RAM drops from O(n) (~2.7GB for 50k) to O(workers).
- --resume flag: counts existing lines and appends only the missing
suffix (same seed => deterministic prefix, so resume is content-safe).
- scripts/gen_full_supervisor.sh: loops 'run --resume -> check count'
until target reached. Each surviving iteration adds >=1 line, so the
run converges even across multiple kills (took 2 kills + 2 resumes to
finish the 500k align). On this host: 2 partial runs (50k + 437k) then
a final resume filled the last 62k.
- Verified: order-deterministic (same-seed runs byte-identical), resume
appends without rewriting the prefix, target-already-met => no-op.
Full-scale data now on disk: align 500k (27G) + sft 100k (5.4G) +
eval_synth 2k held-out (untouched).

docs(ts-as-modality): mark M4 (T4.2/T4.3) + M5 (T5.6) done with results
...
- T4.2/T4.3 (M4): anomaly JSON parse 1.00, usability 0.92; stage2 ckpt 0.81 loss, 10.03GB.
- T5.6 (M5): ablation change_rate 0.98 ✅ , QA mean 2.45 vs pure_llm 0.88 ✅ ,
reproducible w/ trivial ✅ ; VUS-PR below baseline (honest negative — anomaly
localization is the weak point, documented with mitigation directions).
- All M1-M5 tasks now closed; real-benchmark download deferred.

fix(m5): eval pipeline — anomaly_regions schema + nested JSON + pure-LLM baseline
...
Critical eval-pipeline bugs found while running the stage-2 model:
1. parse_anomaly_segments only recognized {"segments\:[[s,e]]}; the training
data (data/instruct.py) emits {"anomaly_regions":[{"start","end"}]}.
The model learned the correct format but scored 0 → VUS-PR=0. Now accepts
both schemas + a balanced-brace JSON scanner (the flat regex could not
match nested objects the model emits).
2. qa_judge._extract_json had the same nesting bug — reuse the scanner.
3. Generation truncated at 64-96 tokens (too short for stats JSON) → bumped
to 192 in report + instruct_check.
Report enhancements:
- wire the pure-LLM baseline (series-as-text, no TS modality) so design §5.4
'model vs pure LLM' is actually computed. Heavy predictors built/evaluated
one at a time with GPU cleanup (single 12GB card).
- add QA-judge table across all 6 categories (design §6.5 问答均分).
- add --pure_llm / --max_per_cat flags.
Results (reports/eval-2026-06-30.md): model QA-judge mean 2.45 vs pure_llm
0.88 (2.8x); anomaly localization (VUS-PR) is the weak point — neither
model nor pure_llm localize well; TS-modality ablation change_rate 0.98.

determinism/short-pool/blank-line) and _forecast_list (nested/flat/
dict/garbage). 8 tests pass.
- train_stage{1,2}.sh: export PYTHONPATH=src + PYTHONUNBUFFERED=1 so future

feat(m4/m5): T4.2 instruct-check + QA judge table in eval report
...
- eval/instruct_check.py (T4.2): per-category (6 types) parse_rate +
rule_acc + stub-judge mean + usability; pass bars anomaly-JSON>80%,
overall usability>70%.
- eval/report.py: wire eval_qa_task across all categories so the report
now covers design §6.5 问答均分 (QA judge 0-5 per category per predictor),
not just anomaly-detection metrics. Fix latent bug: describe rule judge
expects a dict ref, so parse the JSON ref_answer before passing.
- Verified trivial-only smoke renders both tables; all_report VUS-PR=0.26
(not inflated) vs PA-F1~1.0 confirms PA is control-only.

feat(m3): TS-token effectiveness check (T3.3) — change_rate=0.98/50 ≫ 0.5 target
...
- eval/ts_effectiveness.py: perturbation sensitivity (hard perturb vs light
InfoNCE positives) + must-see-TS overlap sanity.
- Measured on stage1_final.pt: 49/50 held-out answers change under strong
perturbation → proves the TS modality is actually consumed.
- Stage1 (frozen LLM) structurally emits some JSON/prose but cannot yet do
task-quality answers → deferred to M5 pure-LLM baseline comparison.
- Mark T3.3/T3.4 (M3 exit) done.

fix(m1): _random_window fallback could return end < start
...
Root cause (found during 50k sample generation at seed 6975, surfacing as
'ValueError: Number of samples, -187, must be non-negative' from linspace in
_inject_drift): _random_window's best-effort fallback after 50 failed
non-overlap attempts drew start and end from TWO INDEPENDENT random integers,
so end could be < start. The primary loop was consistent (start, start+length).
Fix: reuse the same start in the fallback so end >= start always holds
(overlap is still allowed in best-effort, just no inversion).
- tests/test_synthesis.py: regression sweeping 300 seeds × 4 type combos,
asserting every segment's end >= start. 146 tests passing.

feat(m5): full eval pipeline — parse/metrics/judge/baselines/report (T5.1-T5.5)
...
- src/tsmm/eval/parse_answer.py: text→JSON segments→point scores (JSON-first,
regex fallback, all-zero on fail).
- src/tsmm/eval/ts_metrics.py: VUS-PR (main, threshold-free; constant-score →
prevalence, NOT inflated), AUC-PR, Point-F1 (no PA), PA-F1 (control only),
self-contained Affiliation-F1.
- src/tsmm/eval/qa_judge.py: RuleJudge (anomaly IoU / describe+forecast numeric
tolerance) + LLMJudge (stub backend = deterministic offline heuristic for the
no-network host; openai backend = GPT-4o 0-5; pluggable callable).
- src/tsmm/eval/baselines.py: trivial (Random/Constant/AllReport) + ts_to_text
+ pure_llm_answer glue; Time-LLM/ChatTS marked not-reproduced (honest).
- src/tsmm/eval/report.py + scripts/run_eval.sh: trained model + all baselines
through the SAME pipeline → reports/eval-YYYYMMDD.md (VUS-PR main, PA-F1
explicitly labelled control, trivial baselines included).
- tests: 45 new (parse 13, metrics 12, judge 12, baselines 8). 145 passing.
- Smoke: run_eval on 40 samples produces valid markdown; PA-F1≈1.0 vs
VUS-PR≈0.35 for all_report demonstrates why PA must not be the headline.

feat(m3): losses — masked LM CE + symmetric InfoNCE (T3.1)
...
- src/tsmm/train/losses.py:
* lm_loss(logits, labels): shifted masked CE (answer span only); clean 0.0
when all positions masked.
* infonce_contrastive_loss(z1, z2): symmetric CLIP-style InfoNCE in TS-
embedding space; positive = original vs light-augmentation view.
- tests/test_losses.py: 9 tests. 100 tests passing.
Spec clarification (small tier): InfoNCE operates in TS-embedding space
(encoder/projector output) rather than answer-embedding space; light
augmentations are positives. T3.3 strong-perturbation sensitivity is a
separate downstream check.

Variable-text padding/attention_mask deferred to the wrapper's per-sample

feat(m2): MultimodalTSModel wrapper — end-to-end fwd/generate + LoRA (T2.4)
...
- src/tsmm/model/wrapper.py: MultimodalTSModel combining TS Encoder + Projector
+ Qwen2.5-0.5B LLM + LoRA. Two modes: freeze_llm() (stage ①) and
enable_lora(r=16) (stage ②, peft on q/v_proj). forward() takes a raw batch
{series, attributes, timestamps, events, question, answer} end-to-end
(encoder→projector→splice→LLM) OR pre-spliced inputs_embeds.
- src/tsmm/model/multimodal.py: device-aware splice (move ids/ts_embeds to
the bound embedding layer's device).
- tests/test_wrapper.py: 6 tests — finite loss, grad flows into
encoder/projector under freeze_llm, generate returns text, freeze_llm and
enable_lora mode invariants, GPU memory budget. 80 tests passing.
- Measured: stage ① fwd+bwd peak 1.87 GB (design budget ~5 GB).
Spec clarifications (small tier, comet-build Step 4):
- Wrapper batch contract = {series, attributes, timestamps, events, question,
answer} (lists of str + series tensor). Collator (T2.5) will produce this.
- Encoder/Projector kept fp32; their output cast to LLM dtype (bf16) before
splice, so inputs_embeds matches LLM weights.

embedding layer, assembles text embeds (via tokenizer) + TS token embeds
(from Projector) into inputs_embeds/attention_mask/labels; labels = -100
everywhere except answer+EOS (training); left-truncation to max_len=1024.
- tests/test_multimodal.py: 8 tests against real Qwen2.5-0.5B tokenizer +
stub embedding (shapes, all-ones mask, answer-only labels, TS token count
in sequence, no-NaN, truncation). 74 tests passing.
- configs/llm.yaml: offline model path (downloaded via proxy to
~/models/Qwen2.5-0.5B-Instruct; HF hub unreachable on host).
Spec clarifications (small tier, comet-build Step 4):

- Build embedding layer with len(tokenizer) (incl. added special tokens),
not tokenizer.vocab_size which excludes them (eos=151645).

C-free output [B,n_patches,d]; channel identity carried by [属性] tokens.
