# Targeted ICASSP 2027 manuscript

This directory is an independent acceptance-target manuscript. It does not
modify or replace `../main/`.

## Positioning

The paper now starts from the egocentric conversational agent's when-to-speak
problem, positions it against 27 cited works in turn-taking, first-person
audio-visual conversation, active-speaker modeling, and streaming Omni
interaction, then studies two cutoff-aligned interfaces:

- **short-window encoder evidence (SWE)**: direct recent audio and optional
  person-crop visual encoder features alongside the frozen Omni readout;
- **partial-tail refresh (PTR)**: query only the observed prefix of the current
  two-second block at each 200-ms cutoff, reusing completed payloads.

The evidence remains a causal global--local **audit**, not a claim that all
Omni models lack local perception or that PTR's independent gain is proven:

- global Omni context and recent audio are complementary across all horizons;
- most measured benefit is dense forecasting and wearer-offset anticipation;
- pooled and current-frame person vision do not establish speaker grounding;
- a three-seed causal oracle shows that timely visible-participant activity is
  informative, while identity continuity is not currently necessary.

The draft also reflects two seed-0 exploratory screens reported in
`../main/main.tex`: no-box full-frame F3 (Table 1) and a global-only
chunk-construction comparison (Table 4). Neither supplies
matched visual-motion evidence, endpoint gains, or the pending T/C factorial.
The result directories cited by the main draft for F3 and its G+A recheck
are absent from this checkout, so their underlying logs have not been
independently audited here.

The Results section also reports the archived 2026-08-24 sparse Thinker-LoRA
diagnostic as a separate historical screen. Its strict causal-valid mean mAP
declined under the recorded LoRA recipes, but the legacy feature/head contract
is not matched to the current G+A matrix, and the remote raw metrics and
checkpoints are unavailable here. It is not a Table 1 model ranking or proof
that LoRA cannot help this task.

No semantic ENTRY/YIELD, addressee, online-detector, or real-time-throughput
claim is made. The deployable matrix is explicitly single-seed and exploratory.
EasyCom has archived screening scores. The Ego4D manifest and extraction /
training workflow exist, but this checkout has no archived Ego4D test metrics;
the manuscript specifies its transfer protocol and explicitly leaves any
cross-dataset performance claim pending.
The six-group L/T/C/B/H-Q/S table remains in `main.tex` as an
**illustrative, unmeasured planning aid**, excluded from the page-limited
PDF. Its directional statements are hypotheses and falsifiers, not EasyCom
scores. Replace or remove every row after the corresponding experiment,
including results that contradict the working story.

## Build

```bash
cd manuscript/targeted
make
```

The editable sources are `main.tex`, `tables_compact.tex`, `references.bib`,
`figures/task_overview.tex`, and `figures/system_overview_onecolumn.tex`.
Generated LaTeX files are written to `build/`.

The preview targets four technical pages plus a reference-only fifth page. Both
the task diagram (Fig. 1) and the system diagram (Fig. 2) occupy one column.
The current PDF reserves seven numbered result tables. Table 1 spans two
columns and reports 0.2--2.0-s mAP for EasyCom and the pending Ego4D transfer
rows. Only three EasyCom models have archived complete horizon curves; other
intermediate cells remain unavailable. The old Table 1B oracle audit,
Table 2A T/C matrix, and Table 2B chunk screen are now standalone Tables
2--4. B (including an Ego4D transfer slot), H, and S occupy Tables 5--7.
Pending cells are explicitly unmeasured. Active table layouts are in
`tables_compact.tex`; the earlier full-precision tabulars
remain disabled in `main.tex` for source-level auditing.
Figure 3 is an H/Q case slot, not a selected or measured example. Its
cutoff-marked timelines must be inserted only after the slice protocol and
case-selection rule are frozen. The single-column system figure is generated
from figures/system_overview_onecolumn.tex; the earlier full-width source
is retained for comparison.

The build uses the repository's ICASSP 2027 LaTeX assets in
`../ICASSP2027_Paper_Templates/`, selected by `latexmkrc`. The supplied
`spconf.sty` and `IEEEbib.bst` match the 2026 copies.
