emit.py

The recording tool: every code, theme, disposition and pointer is a call, appended to a journal.

What it holds

The Emit class: stage, code, pointer, thread, threads_bulk, theme, theme_add, retract, reading and close. Each call appends one line to out/_journal.jsonl. close() writes codes.jsonl, themes.jsonl, threads.jsonl, pointers.jsonl and _run.json from the journal. It checks each quote against the record, refuses a code on an item read.py never served or on a context opening, and in v32 refuses a large read exclusion without a cited line.

Who writes it, and when

The instrument's author. Coders and the lead call it while working; only the case lead calls close().

Why it exists

"If a step's output is a file, the agent is never the thing that formats it." The stage stamp makes discovered_at "a measurement instead of a claim". Append-only means "nothing is revised", and "if the journal and the final outputs ever disagree, the journal is right."
