# Context Strategy

## 1. Default Strategy

The main orchestrator should not process the full source in one context.

Use:

```text
main session -> source registration and orchestration
whole-source gestalt reviewer -> full-source high-context structure review
worker thread -> bounded range processing
file handoff -> durable cross-session state
```

The whole-source gestalt reviewer is a real sub-session participant, not the main session. It exists to preserve the overall shape of coherent long discussions before range workers begin.

## 2. Whole-Source Gestalt Rule

For coherent discussion drafts that fit inside a high-context participant, run a whole-source gestalt pass before segmentation.

The pass must judge:

```text
- whether the source is one coherent topic or several loosely related topics
- the global topic portrait
- the main structural layers
- core tensions and governing questions
- model-evolution lines
- likely parent/child/tool/case/action-layer distinctions
- risks that chunk-first workers may flatten into false peer topics
```

If the source is too large or not coherent enough for one gestalt pass, record the exception and use a small number of macro-range gestalt passes before worker segmentation.

## 3. Range Order

```text
1. H1 rounds: R01, R02, R03
2. H2 sections when a round is too large
3. source block batches when a section is too large
```

## 4. Worker Input

Each worker gets:

```text
- thread-start packet
- participant invocation packet
- exact source range
- accepted whole-source gestalt summary or recorded exception
- output path
- forbidden actions
- return packet template
```

Workers should use the gestalt summary as orientation. They may challenge it with local evidence, but they must explicitly mark the challenge and cite the source range.

## 5. Worker Output

Each worker writes:

```text
- participant output file
- execution or returned-output record
- thread-return packet
- unresolved issue list, if needed
```

## 6. Main Session Reading Rule

The main session reads worker summaries and indexes first. It reads source excerpts only for verification or repair.

The main session may read the accepted whole-source gestalt output because it is a participant result with a record. It must not replace that result with its own informal full-source judgment.

## 7. Continuation Rule

Create a continuation handoff after each major pass or before any expected context pressure.
