# 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 `latexmkrc` 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.

VS Code's LaTeX Workshop extension is supported when the repository is opened
as the workspace. Open `main.tex` and run **LaTeX Workshop: Build LaTeX
project**. The workspace setting writes output to `build/`, while `latexmkrc`
provides the template and bibliography-style search paths to both LaTeX
Workshop and command-line builds.

Current source layout:

```text
main/
  main.tex
  references.bib
  figures/
    method_architecture.tex  # reproducible TikZ source
    method_architecture.pdf  # manuscript-ready vector figure
  latexmkrc
  Makefile
  README.md
  build/            # generated, ignored
```

Running `make` regenerates the method figure when its TikZ source changes
before compiling the manuscript. 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 remains outside the core method and main comparison; it appears
  only as a scoped streaming/cache diagnostic with a matched Qwen 1-Hz
  causal-hold control, and its 5-Hz cache row requires equivalence and leakage
  audits before reporting;
- 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.
