v2.0.0

2.0.0 (2026-02-18)

Features

• auth: replace static hotkey/API-key auth with Bittensor validator whitelisting and 50% consensus (#5) (a573ad0)

BREAKING CHANGES

• auth: WORKER_API_KEY env var and X-Api-Key header no longer required.
  All validators on Bittensor netuid 100 with sufficient stake are auto-whitelisted.

• ci: trigger CI run

• fix(security): address auth bypass, input validation, and config issues

• Move nonce consumption AFTER signature verification in verify_request()
  to prevent attackers from burning legitimate nonces via invalid signatures
• Fix TOCTOU race in NonceStore::check_and_insert() using atomic DashMap
  entry API instead of separate contains_key + insert
• Add input length limits for auth headers (hotkey 128B, nonce 256B,
  signature 256B) to prevent memory exhaustion via oversized values
• Add consensus_threshold validation in Config::from_env() — must be
  in range (0.0, 1.0], panics at startup if invalid
• Add saturating conversion for consensus required calculation to prevent
  integer overflow on f64→usize cast
• Add tests for all security fixes

• fix(dead-code): remove orphaned default_concurrent fn and unnecessary allow(dead_code)

• fix: code quality issues in bittensor validator consensus

• Extract magic number 100 to configurable MAX_PENDING_CONSENSUS
• Restore #[allow(dead_code)] on DEFAULT_MAX_OUTPUT_BYTES constant
• Use anyhow::Context instead of map_err(anyhow::anyhow!) in validator_whitelist

• fix(security): address race condition, config panic, SS58 checksum, and container security

• consensus.rs: Fix TOCTOU race condition in record_vote by using
  DashMap entry API (remove_entry) to atomically check votes and remove
  entry while holding the shard lock, preventing concurrent threads from
  inserting votes between drop and remove
• config.rs: Replace assert! with proper Result<Self, String> return
  from Config::from_env() to avoid panicking in production on invalid
  CONSENSUS_THRESHOLD values
• main.rs: Update Config::from_env() call to handle Result with expect
• auth.rs: Add SS58 checksum verification using Blake2b-512 (correct
  Substrate algorithm) in ss58_to_public_key_bytes to reject addresses
  with corrupted checksums; previously only decoded base58 without
  validating the 2-byte checksum suffix
• Dockerfile: Add non-root executor user for container runtime security

• fix(dead-code): remove unused max_output_bytes config field and constant

Remove DEFAULT_MAX_OUTPUT_BYTES constant and max_output_bytes Config field
that were defined and populated from env but never read anywhere outside
config.rs. Both had #[allow(dead_code)] annotations suppressing warnings.

• fix(quality): replace expect/unwrap with proper error handling, extract magic numbers to constants

• main.rs: Replace .expect() on Config::from_env() with match + tracing::error! + process::exit(1)
• validator_whitelist.rs: Extract retry count (3) and backoff base (2) to named constants
• validator_whitelist.rs: Replace unwrap_or_else on Option with if-let pattern
• consensus.rs: Extract reaper interval (30s) to REAPER_INTERVAL_SECS constant

• fix(security): address multiple security vulnerabilities in PR files

• consensus.rs: Remove archive_data storage from PendingConsensus to
  prevent memory exhaustion (up to 50GB with 100 pending × 500MB each).
  Callers now use their own archive bytes since all votes for the same
  hash have identical data.

• handlers.rs: Stream multipart upload with per-chunk size enforcement
  instead of buffering entire archive before checking size limit.
  Sanitize error messages to not leak internal details (file paths,
  extraction errors) to clients; log details server-side instead.

• auth.rs: Add nonce format validation requiring non-empty printable
  ASCII characters (defense-in-depth against log injection and empty
  nonce edge cases).

• main.rs: Replace .unwrap() on TcpListener::bind and axum::serve with
  proper error logging and process::exit per AGENTS.md rules.

• ws.rs: Replace .unwrap() on serde_json::to_string with
  unwrap_or_default() to comply with AGENTS.md no-unwrap rule.

• fix(dead-code): rename misleading underscore-prefixed variable in consensus

• fix(quality): replace unwrap/expect with proper error handling in production code

• main.rs:21: Replace .parse().unwrap() on tracing directive with
  unwrap_or_else fallback to INFO level directive
• main.rs:36: Replace .expect() on workspace dir creation with
  error log + process::exit(1) pattern
• main.rs:110: Replace .expect() on ctrl_c handler with if-let-Err
  that logs and returns gracefully
• executor.rs:189: Replace semaphore.acquire().unwrap() with match
  that handles closed semaphore by creating a failed TaskResult

All changes follow AGENTS.md rule: no .unwrap()/.expect() in
production code paths. Test code is unchanged.

• docs: refresh AGENTS.md
