security / protocol:
- Derive a PER-KEY junk marker (obfuscation.rs, info byte 0x04) instead of the
global constant [0x88,0x1A,0x93,0x5D]. A fixed marker was a universal DPI
signature identifying ALL OSTP users at once — exactly what the HKDF version
gate avoids for the handshake. Server drops junk via a new DispatchOutcome::Junk
inside the existing key-trial loop (secrets already derived → zero extra cost);
client stamps its own key's marker.
- §E: configurable junk/fragmentation params (junk_pc / junk_ps / frag_chunk / frag_sleep).
GUI (desktop):
- Light theme + toggle, GUI version footer in Settings.
- Fix mouse-wheel scroll on Settings (flex child needed min-height: 0).
- Drop the false "process exclusions unsupported in TUN mode" warning — they DO
work (native_handler maps port->process via GetExtendedTcpTable).
release / infra:
- build.ps1: add -PreRelease (tag CURRENT version as v<ver>-beta.N, no bump, no
master commit); guard the panel build when ostp-control ships no source; bump
the real ostp-gui/package.json instead of the nonexistent ostp-control one.
- release.yml: mark hyphenated tags as GitHub pre-releases; don't hard-fail the
web-panel step when there is no source (use committed dist/).
- Versions aligned to 0.4.1; README license badge BSL 1.1 -> AGPL v3.

Ported only the fixes that actually apply to the pre-refactor base
(the handshake fixes 6eb7b36/d65af35 fix bugs the 0.3.1 multi-server
refactor introduced into the new outbounds/ostp.rs; the base bridge.rs
already waits for the handshake response with retransmit + NAT64
fallback, so they are intentionally skipped).
- EMFILE (922cf0b): rlimit::increase_nofile_limit at CLI startup.
- Logs (1151726): UoT connect/disconnect → debug; rate-limit the
unauthorized-probe log to one line / ~30s so a junk/probe flood can't
spam the log (and a client running junk-over-UDP can't self-ban).
- Helper lifecycle + bypass routes (b6e78c1):
* ostp-tun-helper forces std::process::exit(0) after run_server so the
WinTun adapter and its metric-0 default route are reclaimed instead
of lingering as a zombie that breaks the next connect.
* windows_route: delete_routes_for_dest() purges stale /32s, dedupe
bypass IPs, and log add failures at warn!.
* windows: retry tun::create through the transient ERROR_INVALID_
PARAMETER window and widen the adapter-index lookup to ~15s.

Clean-rebuild on the stably-working v0.2.98 base. The project's stealth
path is zapret-like (packet obfuscation / junk / fragmentation), NOT
TLS-mimicry, so WSS and Reality are dropped entirely.
- Delete dead orphan files: ostp-client/src/transport/xhttp.rs and
ostp-core/src/crypto/reality.rs (never declared as modules → not even
compiled), plus ostp-core/src/framing/wss.rs.
- Scrub the `wss` transport field from client config/bridge, the unified
CLI (ostp/src/main.rs), the Tauri GUI backend, the GUI frontend
(index.html/main.js), and the Flutter UI; also drop the Reality
pbk/sid plumbing and XTLS auto-search modes from both frontends.
- Drop now-unused client deps (x25519-dalek, chacha20poly1305, hex).
- Bump workspace to version 0.4.0 and license AGPL-3.0; make ostp's
ostp-core dep path-only so the version bump resolves.
- gitignore ostp-control/ (panel assets built separately; a dummy dist
is created for the rust-embed build).

The core bug: server sent 5 TLS records in server_hello but client only
read the first one (ServerHello), then passed remaining bytes (CCS + fake
records) into RealityStream. RealityStream saw 0x14 (CCS) != 0x17 and
immediately returned an error, killing the connection.
Changes:
- reality.rs: append ChangeCipherSpec after ClientHello (RFC 8446 D.4)
export REALITY_SERVER_HANDSHAKE_RECORDS=5 constant
- xhttp.rs: drain all 5 server handshake records before creating RealityStream
- uot.rs: rebuild server_hello as proper 5-record TLS 1.3 flight:
ServerHello + CCS + fake EE (108B) + fake Cert (812B) + fake Fin (52B)
drain client CCS from raw stream before wrapping in RealityStream
