Prove the Puppetmaster Jev transition oracle: unset never networks,

# Verify Puppetmaster Jev
Library plus CLI. Isolated temp store. Never use the user's live
`.puppetmaster/` state. Never print an OpenRouter key.
## Launch
Ready: `python -m unittest tests.test_jev_transition -q` exits 0 from
the Jev worktree (`Puppetmaster-jev-oracle` or the product checkout
that contains `puppetmaster/jev/`).
```bash
cd "$REPO"
.venv/bin/python -m unittest tests.test_jev_transition -q
```
Use the repo venv if present; otherwise `python3` on PATH. Teardown is
the process exit. Helpers write under `/tmp/verify-this/puppetmaster-jev/`
and must not delete prior receipts.
## Doctor
```bash
.cursor/skills/verify-puppetmaster-jev/scripts/doctor.py
```
Must report:
- `opted_in=false` and `acting=false` in a cleared env
- `test_jev_transition` importable
- no `PUPPETMASTER_JEV` / `PUPPETMASTER_JEV_ACT` leak from the host
after `hermetic_env` import
If doctor fails, fix the tree. Do not drive live Decisions.
## Drive
Prefer the helper, then unittest, then an optional live observe.
```bash
.cursor/skills/verify-puppetmaster-jev/scripts/prove_observe.py
```
Mapped features: [features/README.md](features/README.md).
## Evidence
A pass is:
1. Helper JSON at `/tmp/verify-this/puppetmaster-jev/observe.json`
2. `v1_acts_on_opt_in=true` (auditor skipped without `JEV_ACT`)
3. `v234_match_today=true` (launch / admit / enqueue unchanged)
4. Unittest exit 0
5. `show` / stitcher preview contains `## Jev` only when a
`jev_transition` GATE exists
Live Decisions are optional and only when the user named a key source.
Load the key in-process. Never write it to evidence.
## Cleanup
Kill only the helper/unittest PIDs this run started. Leave
`/tmp/verify-this/puppetmaster-jev/` in place.
## Helpers
- `.cursor/skills/verify-puppetmaster-jev/scripts/doctor.py`
- `.cursor/skills/verify-puppetmaster-jev/scripts/prove_observe.py`
