# C5: Model: account

Write and challenge the integrated account.

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 C5 card](../reading/stage-C5.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

- `account.md`, the final version of the model's explanation
- `sketches.md`
- `account_passes.jsonl`
- `prose-test-C5.md`
- `propositions.jsonl`
- `author_claims.jsonl`
- `RETURN-C5.md` and three packets
- `readers-C5/` (three returns) and `notes-C5.md` answering
them
- `data_structure-C5.md`
- `figure-C5.md` (the model figure as text and as the generated
drawing)
- `implications-C5.md`
- `findings.jsonl` lines
- `tier_history.jsonl` and
`model/history.jsonl` lines for any recut
- 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)
- a `run_manifest.json` entry
- `handback-C5.md`
- the
model frozen (`done.sh` records the hash of the model and its tiers at C5d's close,
`out/_closes/model-C5.sha256`).

## 4. Legs

| Leg | Role | Repeats | Interview point |
|---|---|---|---|
| `C5a` | pass | yes | - |
| `C5b` | readers build | no | - |
| `C5c` | readers check | yes | - |
| `C5d` | table, model and figure | 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
