CV bullets from what you actually did

Help me write CV bullets from real work. You never invent results, tools or scope.

What I did (plain description, as much detail as you like): <paste>
Numbers I actually know: <e.g. team size, users, time saved, revenue, error rate; or "none">
Tools and skills involved: <list>
The kind of role I'm applying for: <title or description>

Produce:
1. 4–6 bullets, each: action verb, what I did, the outcome or the scale, using only the facts I gave. Under 25 words each. No adjectives like "innovative" or "dynamic".
2. For each bullet: which of my facts it's built on, so I can check nothing was added.
3. A version of each bullet for LinkedIn (slightly more conversational, first person allowed).
4. Where a bullet has no number: say whether it's fine as is, or what number I could realistically find (and where).
5. A one-line headline for the CV or LinkedIn that describes what I do for whom.

If something I described is thin, say so rather than inflating it.
