T15: buang voter basi di scan + hapus bobot suara & UI basi di web

get_voters.py kini menyimpan hanya pemilih segar (last_vote tak
diketahui atau > VEX_STALE_DAYS dibuang di normalize, V13). Web
menampilkan kolom RANK/AKUN/STAKE/VOTE TERAKHIR, tanpa BOBOT SUARA,
stat VOTE BASI, penanda/ filter ?stale=1 (V15). voters.db dipangkas
336 → 42. Oracle diperbarui dan lolos.

 - Python tool (production): `./venv/bin/python get_voters.py`. venv is Python 3.12, deps `requests` + `flask` + `python-dotenv` (`requirements.txt`). Install with `./venv/bin/pip install -r requirements.txt`.
 - Web dashboard (read-only, reads `voters.db`): production `./venv/bin/gunicorn -c gunicorn.conf.py dashboard:app` → http://127.0.0.1:5000/ (run from repo dir). `gunicorn.conf.py` imports `config` → `.env` honored; `DASH_WORKERS` (default 2) controls workers, `DASH_HOST`/`DASH_PORT` the bind. Dev server (single-process) still works via `./venv/bin/python dashboard.py`. Paged 50/page, sorted `staked DESC`, live owner search (`/api/search`). Data freshness comes from the daily scan run — the dashboard never scans.
 - Config: all tunables load from env / `.env` via `config.py` (python-dotenv): `VEX_TARGET_BP`, `VEX_API_NODE`, `VEX_DB_PATH`, `VEX_MIN_STAKED_VEX`, `DASH_PAGE_SIZE`, `DASH_HOST`, `DASH_PORT`, `DASH_WORKERS`, `VEX_STALE_DAYS`. Copy `.env.example` → `.env` to override; `.env` is gitignored. Chain constants (`vexcore`/scope/table) stay hardcoded.

 - Tests (the verification oracles): `./venv/bin/python test_get_voters.py` and `./venv/bin/python test_dashboard.py` must both exit 0. They mock the network / use a temp DB — the live node is too flaky/slow for a full-scan test. Run after touching the relevant file.
 
 ## Key facts
@@ -20,12 +20,13 @@ Two tools scan the Vexanium blockchain voters table for accounts whose only vote
 - The node sometimes returns `staked` as a string instead of a number — normalize coerces to float (spec §V8).
 - The voters table has a sentinel first row (`owner="...........q"`, uint64 0) that must be skipped.
 - Authoritative vote weight is `last_vote_weight` (high-precision decimal string) — stored verbatim as TEXT, never float-converted (spec §V6).
-- Stale-vote flag (spec §V13): `last_vote` (estimated last re-vote date) is derived at scan time from the Vexanium weight formula `last_vote_weight = staked_raw × 2^(years since 2000)` → `log2(weight / (staked×10000))`. A voter is `stale` when `last_vote` is older than `VEX_STALE_DAYS` (default 28). Filter via `?stale=1`.
+- Freshness filter (spec §V13): `last_vote` (estimated last re-vote date) is derived at scan time from the Vexanium weight formula `last_vote_weight = staked_raw × 2^(years since 2000)` → `log2(weight / (staked×10000))`. Voters whose `last_vote` is older than `VEX_STALE_DAYS` (default 28) — or can't be derived (zero/empty weight) — are dropped in `normalize()` and never stored; the dashboard therefore shows only fresh voters (no stale UI).
+- The web list shows RANK / AKUN / STAKE (VEX) / VOTE TERAKHIR columns (3 stats cells). Vote weight stays in the DB and `/api/search` JSON but is not rendered as a column.
 
 ## Layout
 
 - `SPEC.md` — spec (goal/constraints/interfaces/invariants/tasks/bug log), in caveman encoding. Build/backprop flow through it.
-- `get_voters.py` — production fetcher: scan → filter → SQLite `voters.db` (each run replaces the table = daily snapshot, with `scanned_at` + derived `last_vote`; never appends history).
+- `get_voters.py` — production fetcher: scan → filter (stake + freshness, basi dibuang) → SQLite `voters.db` (each run replaces the table = daily snapshot, with `scanned_at` + derived `last_vote`; never appends history).
 - `get_voters.js` — reference implementation only.
 - `dashboard.py` + `templates/index.html` + `static/style.css` + `static/app.js` — Flask web dashboard; reads `voters.db`, styled per `DESIGN.md`; `app.js` = debounced live owner search (fetch `/api/search`), degrades to the server-side `?q=` GET form if JS is off.
 - `config.py` — loads env/`.env` (python-dotenv) → `TARGET_BP`, `API_NODE`, `DB_PATH`, `MIN_STAKED_VEX`, `PAGE_SIZE`, `DASH_HOST`, `DASH_PORT`, `DASH_WORKERS`, `VEX_STALE_DAYS`; shared by get_voters & dashboard.
