On SIGHUP, re-read the YAML config file and update mutable runtime
settings: timeout, retries, log_level, and pool config (sources,
intervals, thresholds). Pool triggers an immediate source re-fetch.
Listen address and chain require restart.
Add warm start and chain pre-flight sections to USAGE. Mark both
features complete in ROADMAP and TASKS. Remove implemented items
from TODO. Update README, PROJECT, and CHEATSHEET.
Test the static chain (without pool proxy) before running pool health
tests. If the chain itself is unreachable, skip proxy testing and log a
clear warning. Prevents false mass-failure when the issue is upstream
(e.g., Tor is down), not the exit proxies.
On warm start (state has alive proxies), only quick-test the
previously-alive subset before serving. Full health test runs in
background. Cold start behavior unchanged (test all before serving).
Reduces startup blocking from minutes to seconds on warm restarts.
Add failure backoff and stale expiry sections to USAGE. Document pool=
field in metrics output. Update ROADMAP, TASKS, TODO with completed
items and remaining suggestions. Add metrics example to CHEATSHEET.
Evict proxies not returned by sources for >3 refresh cycles and not
currently alive. Cleans up proxies removed upstream faster than waiting
for max_fails consecutive health test failures.
Track last_fail timestamp on ProxyEntry. When a connection attempt fails
in server.py, report_failure() records the time. The selection weight
multiplies by min(fail_age/60, 1.0), ramping back from floor over 60s.
Prevents wasting retries on proxies that just failed.
Add selection weight section to USAGE.md with decay formula and
reference table. Mark feature complete in ROADMAP and TASKS.
Update README and PROJECT descriptions.
Replace uniform random.choice with random.choices weighted by last_ok
recency. Proxies tested successfully more recently get higher selection
probability (weight = 1/(1 + age/300)), decaying over ~5 minutes.
Update all docs for managed proxy pool: README, USAGE, CHEATSHEET,
PROJECT, TASKS, and example config. Document multi-source config,
proxy file format, health testing, persistence, and legacy compat.

ProxyPool replaces ProxySource with:
- Multiple sources: HTTP APIs and text files (one proxy URL per line)
- Deduplication by proto://host:port
- Health testing: full chain test with configurable concurrency
- Mass-failure guard: skip eviction when >90% fail
- Background loops for periodic refresh and health checks
- JSON state persistence with atomic writes (warm starts)
- Backward compat: ProxySource still works for legacy configs

Add PoolSourceConfig and ProxyPoolConfig for multi-source proxy pool
with health testing. Config supports both HTTP API and file sources.
Backward compat: legacy proxy_source YAML key auto-converts to
proxy_pool. CLI -S flag creates ProxyPoolConfig with single source.

Moves _negotiate_hop() and build_chain() from server.py to proto.py
to break circular import between server and the upcoming pool module.

Retry failed proxy connections with a fresh random proxy on each
attempt (configurable via retries setting, proxy_source only).
Track connection metrics and log summary every 60s and on shutdown.

Fetches proxies from an HTTP API, caches them in memory, and appends
a random proxy to the chain on each connection. Supports proto/country
filters and configurable refresh interval.
Config: proxy_source.url, proto, country, limit, refresh
CLI: -S/--proxy-source URL
Asyncio-based SOCKS5 server that tunnels connections through
configurable chains of SOCKS5, SOCKS4/4a, and HTTP CONNECT proxies.
Tor integration via standard SOCKS5 hop.
