The current draft uses causal local evidence adaptation as the single umbrella for recent modality evidence and cutoff-aligned Omni tail access. It supersedes the older scope description below; historical strategy docs remain records of their dates. The new scoped decision is ../../docs/manuscript_local_evidence_structure_2026-09-17.md.

Method has two subsections: Model Architecture (task, global/local features, fusion and learning) and Streaming Inference Architecture (8-s maximum context, completed-history reuse, temporary current tail, cutoff alignment). Only one displayed fusion equation remains.
The core is frozen Qwen Omni G + recent 1-s Qwen audio A; pooled person vision is optional, not an established performance contribution.
The three contributions cover global--local adaptation, its partial-tail streaming realization, and controlled dense versus onset/offset analysis. Caching alone is not claimed as a new algorithm; mechanism gains await matched controls.
The method figure now depicts that actual core rather than an unmeasured 25-Hz MuVAP person-attention branch. Preserved-EgoSpeak residual fusion and its block-phase embedding are auxiliary controls, not the default head.
Semantic opportunity evaluation is deferred during annotation auditing. Its historical protocol and workload are preserved in annotation_protocol_notes.tex, which is deliberately not included in the submission PDF. Historical results remain in the original results/ and reports/ records.
Analysis uses Main Comparison, Local Evidence Analysis, Streaming and Context Analysis, and Error and Qualitative Analysis. Omni LoRA is deferred. Planned experiments are in the dated experiment log.
Locked main rows and the tail-refresh x local-audio / context-cap table are unmeasured placeholders, not zero or mixed-protocol confirmatory numbers. Historical main-table screens are identified explicitly. Already inspected official-test runs remain exploratory despite additional seed repetitions.
The main table now includes an exploratory F3 seed-0 no-box full-frame screen and the re-evaluated G+A dense horizon curve, both under causal_valid_only. F3's 0.2-s/ten-horizon mAP is 82.38/65.54 versus G+A's 81.72/65.11. This is not a matched visual-motion claim: F2, matched capacity/history controls, boundary evaluation, and repeat seeds are still missing. Source records: F3 and G+A.
Backbone transfer adds paired G/GA controls for Qwen2.5-Omni 3B/7B and MiniCPM-o 4.5, fixing the same local audio sidecar. Compact table deltas are pending and require readout/refresh/history audits; MiniCPM is not yet GPU-verified or an established matched 8-s stream. This scoped transfer overrides the older cache-diagnostic-only restriction below, not the 3B core.
The body targets four technical pages with one method figure, one main table, one compact streaming/transfer controls table, and one error/qualitative figure slot. The optional fifth page is references only; replace TODOs rather than keep appending, and finalize author kit and applicable AI-drafting disclosure.

Build and historical scope

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:

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:

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. 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.
