A fleet batch (fleet/batch_NN/)

One fleet coder's directory: its slice, its tools, and what it wrote.

What it holds

Inputs: AGENT.md, CONTRACT.md, CONTRACT-fleet-coder.md, brief.md, timeline.md and lexicon.md (as the lead's out/ held them at dispatch), corpus.txt and coder_corpus.jsonl (the slice and its context openings), read.py, cite.py, emit.py, close_run.py, _manifest.json. In out/: case.md and notes.md (the coder's), codes.jsonl, themes.jsonl, threads.jsonl, pointers.jsonl (written at consolidate), _run.json, _read.jsonl, _read_index.json, final_message.md and _transcript.jsonl (placed by the scheduler). The journal is out/_journal.jsonl.

Who writes it, and when

fleet.py dispatch builds it; one coder works in it; the scheduler places the transcript and final message and runs check --batch NN; collect and consolidate read from it. A failed batch moves whole to fleet/_failed/.

Why it exists

Branch B splits a room above 500 items into slices read "one at a time: the fleet is serial because each coder inherits the facts files of the one before" (scheduler's contract). The coder sees no other coder's codes, case or notes.

Where

run/fleet/batch_NN/ inside each room's run.tar.zst.

Checked against: tools/fleet.py, newrun.py, CONTRACT-fleet-coder.v32.md, CONTRACT-scheduler.md
