Reflect the crypto hardening in the EN/RU specification:
- Section 6: transport keys now come from Noise Split() over the chaining
key ck (includes the ee DH secret), giving forward secrecy; added the
rationale for why keys must NOT come from the handshake hash h, and the
wire-version-5 gate.
- Section 8: documented the handshake-trial CPU-DoS defense (per-key
secret/marker caching + trial-path token bucket).
- Corrected the handshake replay window (±300s / 5min, was mis-stated as
±30s) and PSK derivation (HKDF-SHA256).
- README.md/README.ru.md: License section still said "Business Source
License 1.1 ... converts to MIT in 2030" while the badge right above it,
Cargo.toml, and LICENSE itself all say AGPL-3.0 — a direct contradiction.
Now both say AGPL-3.0 and link to LICENSE.
- README.md/README.ru.md: CLI Reference / Quick Start described the old
flag-based interface (--init, --check, --generate-key, --links, bare
positional URL) that no longer exists after the subcommand refactor.
Rewrote both to the current `ostp <command>` surface (run/connect/setup/
init/check/gk/links/import/update/migrate/prober/proxy-env/uninstall),
including gk's alias and update's --branch/--version. RU previously had
no command reference at all; added one to match EN.
- docs/{en,ru}/obfuscation.md: removed the XTLS-Reality section (feature
removed in §A) and replaced it with an accurate description of junk
packets + TCP fragmentation, the actual current supplementary stealth
mechanism, including the per-key junk marker (no global DPI signature).
Also corrected the key-derivation and masking-algorithm descriptions,
which described a much older scheme (SHA-256(access_key)[0..8] + static/
nonce-based XOR) than what derive_all_secrets()/derive_payload_mask()
actually implement now (HKDF with version-gated, domain-separated
outputs; HMAC-SHA256 mask keyed on the packet's own ciphertext). The RU
version was additionally rewritten out of an oddly formal "industrial
telemetry" register into plain technical Russian.
