# Which file is current?

**`ltl.pdf` / `ltl.tex` — the current paper.** This is the version
submitted to the journal on 2026-07-17 and now frozen during review; the
live copy served at <https://ltl.zkdefi.org/paper> is byte-identical.

The other files are kept as honest history, not as reading material:

| File | What it is |
|---|---|
| `ltl-v0.1.pdf` / `.tex` | early 4-page draft (July 2026), superseded |
| `ltl-v0.2.pdf` / `.tex` | 19-page system-report draft, superseded by a full rewrite |

Revisions v0.3–v0.9 were successive overwrites of `ltl.tex`; they live in
this repository's git history. v0.9 is the submitted version — the
current `ltl.pdf` above.
