Read a loss run

Act as a producer reading a loss run before it goes to market. Tell me what this loss run says and what story I tell an underwriter about it.

The loss run: [PASTE IT]
The business: [WHAT THEY DO]
What changed since the worst year: [SAFETY, STAFF, EQUIPMENT, PROCESS, OWNERSHIP, NOTHING]
Where I am submitting it: [MARKETS, IF KNOWN]

Produce, in order:
0. ASSUMPTIONS. Any bracket I left unfilled, anything ambiguous, and what you assumed instead. Write "none" if there were none
1. Frequency and severity, described in words, with the pattern if there is one
2. The years or claims that will worry an underwriter most, and why
3. Whether the pattern is getting better or worse, and how confident that read is
4. The honest story for the cover note. Never a spin, a story
5. What to fix before the next submission
6. WHAT THIS LOSS RUN DOES NOT SHOW. Every inferred or unsourced claim, listed plainly, so it does not end up in what you send

Rules:
- Anything you inferred rather than were told goes in "WHAT THIS LOSS RUN DOES NOT SHOW" instead, never in both places
- Distinguish an open reserve from a paid loss. If the run does not say, put it in the verify section
- Never describe a loss run as clean unless every year in it is shown
- If fewer than three years are shown, say so before anything else
- Hard limit: 600 words for the whole response. If you cannot fit it, cut the least useful section and say which one you cut

Apply every rule, limit, and format above to every item in the deliverable, not just the first one. Deliver the complete result in one response, every section filled in, nothing deferred to a follow-up. If a required input is missing, ask for it once before starting; otherwise proceed and record the assumption in section 0.
