# C3: Model: literature

Compare the model with the literature.

This is a reading key. The linked contract and card hold the rules.

## 1. Reading order

1. [Contract](../reading/contract.md), [method](../reading/method.md), [standing instructions](../reading/standing.md).
2. Your recorded platform: [Claude](../reading/platform-claude.md) or [Codex](../reading/platform-codex.md).
3. [Full C3 card](../reading/stage-C3.md), then the run's head, diary and handler deliveries as that card prescribes.

## 2. Inputs and permitted reading

Use the full card's startup packet and reading boundaries. Do not use files from later stages merely because this repository contains them. Historical interviews use the files in their selected bundle.

## 3. Outputs, quoted from the card

- `literature-C3.md`
- `findings.jsonl` lines with literature ids
- `mapping-C3.jsonl`
- mechanisms rewritten in `model/arrows.jsonl`, each a `model/history.jsonl` line
- wherever this
stage changes something, `model-C3.md`, `structure-C3.md` and `concept-C3.md`, each a whole
file superseding the stage C2 file (rule 18
- a file holding only what changed is read
downstream as the whole thing), and `manifest-C3.txt`, one line per stage C2 file saying
whether it has a stage C3 successor, which stage C5 reads first
- a recut is not a superseding
file: the tier file is amended and the superseded line goes to `tier_history.jsonl`, as stage
C2 says
- when the third-order tier is recut, `scheme_v2.jsonl` and `assignments_final.jsonl` rewritten
(`mem.py mint`, then `mem.py reassign`, as stage C2 says)
- `notes-C3.md`.

## 4. Legs

| Leg | Role | Repeats | Interview point |
|---|---|---|---|
| `C3a` | contradicting shelf | no | - |
| `C3b` | resembling shelf | no | - |
| `C3c` | the four problems | no | end |

## 5. Checks and handback

The stage card governs its checks. The [handler](../reading/handler.md) and [leg controller](../reading/legs.md) govern opening, close, pause and recovery. Do not infer permission to start from this page. Keep notes and the head current; the conversation and filesystem must match at any resumable close.

## 6. Published record

Status: **finished**, 3 recorded closed legs. This describes source publication `c070d990be88`, not live state.
