C4: Model: the field
Examine the model against the field account when supplied.
This is a reading key. The linked contract and card hold the rules.
Reading order
- Contract, method, standing instructions.
- Your recorded platform: Claude or Codex.
- Full C4 card, then the run's head, diary and handler deliveries as that card prescribes.
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.
Outputs, quoted from the card
field-C4.md; tentative entries in
model/elements.jsonl or model/arrows.jsonl,
each with "origin": "from-field",
"status": "tentative", field_support and a
model/history.jsonl line; wherever this stage changes
something, model-C4.md, structure-C4.md and
concept-C4.md, each a whole file superseding the stage C3
file (or the stage C2 file where C3 wrote none), and
manifest-C4.txt, one line per file of
manifest-C3.txt saying whether it has a stage C4 successor,
which stage C5 reads first; notes-C4.md.
Legs
C4a: the field. Repeats: no. Interview point: end.
Checks and handback
The stage card governs its checks. The handler and leg controller 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.
Published record
Status: finished, 1 recorded closed legs. This
describes source publication c070d990be88, not live
state.
Historical instructions and settings
Source status clarified on 29 October 2026: the Field agent was still working when it supplied C4. This checkpoint contains its interim reading and comments, not a comparison against its completed model. That fuller comparison remains pending.
