Full diagnostic chain (synth→real zero-shot→real finetune→held-out) shows the TS-modality approach works in-distribution but fails to generalize across entities: same SMD dataset, same 38 channels, just a different machine (1→2) collapses output to repetition garbage. Root cause is the lightweight TS encoder (2-layer TF, 2.1M params) learning dataset/machine- specific patterns rather than transferable time-series representations. This is a valuable negative result: it cleanly rules out the '0.5B LLM + 2-layer TS encoder + single-distribution synth training' route for general time-series understanding, which is more credible than any 'looks like it works but never tested cross-domain' result. Records: - tasks.md: M6 diagnostic section (6.1-6.5) with evidence + archive decision - proposal.md: Status header flagging archive + pointer to diagnosis - docs/diagnosis-2026-07-02-cross-domain.md: full evidence chain, root-cause analysis, capability boundaries, asset inventory, restart conditions Project status: archived. Code/data/checkpoints/reports preserved. Restart requires any of: (1) larger encoder + real-data from-scratch training, (2) channel-agnostic patch strategy, (3) multi-dataset joint training with held-out-dataset generalization proof.
tsmm
Time-series as a Modality — an experimental, single-GPU multimodal model that treats multivariate time series as an independent modality, jointly injected into a small LLM (Qwen2.5-0.5B) for time-series question answering and reasoning (ChatTS route).
Status
M1 (data pipeline) under construction. See
docs/superpowers/specs/2026-06-29-ts-as-modality-design.md for the design and
docs/superpowers/plans/2026-06-29-ts-as-modality-plan.md for the task plan.
