# Main ICASSP manuscript

This is the editable paper directory. It uses the unmodified official ICASSP
2026 LaTeX assets stored in `../ICASSP2026_Paper_Templates/`. When the ICASSP
2027 author kit is released, replace or add the official template and update
`TEMPLATE_DIR` in the Makefile only after checking the new instructions.

Compile from this directory:

```bash
make
```

The PDF and all intermediate files are written to `build/`; only source files
belong in Git.

Current source layout:

```text

  main.tex
  references.bib
  Makefile
  README.md
  build/            # generated, ignored
```

The manuscript is intentionally a content skeleton with visible TODOs. Do not
turn planned implementations, controls, or results into completed claims.

The frozen paper story is documented in
[`../../docs/icassp2027_acceptance_storyline_2026-09-10.md`](../../docs/icassp2027_acceptance_storyline_2026-09-10.md).
The paper asks how long-context Omni understanding can be adapted into
sub-second, wearer-relative floor control for an invisible egocentric wearer.
Its single candidate contribution is a causal local floor-evidence adapter:

- Qwen2.5-Omni-3B is the primary global backbone;
- matched LoRA/PEFT is a baseline, not a separate contribution;
- Qwen2.5-Omni-7B is an optional capacity-scaling control;
- the primary local method uses an anonymous, no-ID visible-person set;
- track continuity is conditional and must defeat no-ID/shuffled/capacity
  controls before entering the paper;
- MiniCPM-o and a cross-family sweep are removed from the core plan;
- the oracle is analysis-only motivation, not a deployable method or headline;
- the publication gate is lower competing-risk-censored multi-other false
  entry at matched wearer-onset recall without worse valid onset or yield.

Competing-risk censoring and training-side threshold calibration are now
implemented and unit-tested. The remaining P0 blocker is the real-data event
audit and protocol/scenario freeze; until then, event values are timing-derived
proxies. Already viewed Sessions 1--3 numbers are exploratory internal evidence
and must not appear in the confirmatory paper table.
