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.

feat(m2): Collator — JSONL → wrapper raw batch (T2.5)
...
- src/tsmm/data/collator.py: Collator maps JSONL sample dicts to the wrapper
batch contract {series [B,max_T,max_C], attributes, timestamps, events,
question, answer}. Variable-T pad/truncate, variable-C pad, NaN→fill.
Variable-text padding/attention_mask deferred to the wrapper's per-sample
splice + max_seq padding.
- tests/test_collator.py: 11 tests. End-to-end Collator→Wrapper fwd+bwd+generate
verified (loss finite, peak 2.32 GB, generate emits text). 91 tests passing.

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.

feat(m2): multimodal splice [属性][时间戳][TS tok][事件][问题][回答] (T2.3)
...
- src/tsmm/model/multimodal.py: MultimodalSplicer — binds LLM input
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):
- Training appends answer + EOS to the prompt layout.
- Build embedding layer with len(tokenizer) (incl. added special tokens),
not tokenizer.vocab_size which excludes them (eos=151645).

feat(m2): TS Encoder — Patchify + 2-layer Transformer (T2.1)
...
- src/tsmm/model/ts_encoder.py: Patchify (channel-independent unfold) +
TSEncoder (shared per-channel patch linear, mean-pool over channels,
learnable positional embedding, 2-layer pre-norm Transformer, LayerNorm).
- configs/ts_encoder.yaml: encoder/projector hyperparameters.
- tests/test_ts_encoder.py: 10 tests (shape, n_patches formula, window
values, determinism, gradient flow, param sanity).
- 61 tests passing; GPU fwd/bwd verified on RTX 3060 (39 MB peak).
Spec clarifications (small tier, comet-build Step 4):
- n_patches = (T-P)//S+1 ⇒ 127 for T=512 (design said 128; arithmetic slip).
- 'Channel-independent' = shared per-channel patch embed + mean-pool →
C-free output [B,n_patches,d]; channel identity carried by [属性] tokens.
- Actual params ≈2.1M (design's '≈4M' was a rough estimate).
