AX Principle 2: comments show HOW with real values, not WHAT the type
signature already says. "Send sends an encrypted message over the
connection." adds zero information.

All private handler function comments restated what the function name
already said (AX Principle 2 violation). Replaced with concrete call
examples showing how each handler is invoked.

AX Principle 2: comments show HOW with real values, not WHAT the
signature already says. "processes incoming messages and returns a

HandleMessage is wired up via RegisterWithTransport.

Replace fmt.Errorf with a local testErr type to eliminate the banned
fmt import. The type carries its own usage example comment per AX
Principle 2.

ProtocolError and ResponseHandler had prose descriptions restating
their names — AX Principle 2 violation. Replaced with concrete call
examples showing how callers use each type.

ConnectedPeers() had a comment that restated the function name ("returns
the number of connected peers"), violating AX Principle 2. Replaced with
a concrete usage example showing the guard pattern.

Dimension weights are never reassigned — declaring them as mutable vars
implies changeability that does not exist. Const declares what IS (AX §5).

AX Principle 2 — comments show HOW with real values, not WHAT the

AX principle 10 requires all three categories (Good, Bad, Ugly) per
function. lethean_test.go had only Good for parseComment; Bad (invalid
input, missing keys, empty values) and Ugly (empty string, semicolons
only, duplicate keys, value-with-equals) are now present.

Renamed `allowedPublicKeyMu` to `allowedPublicKeyMutex` in PeerRegistry.
`Mu` is an abbreviation that violates AX Principle 1 (predictable names
over short names) — the full word `Mutex` removes any ambiguity about
what the field represents.

AX Principle 1: predictable names over short names. `resp` and `raw`

'wg' is an abbreviation requiring mental mapping; 'waitGroup' names what
it IS — an explicit sync.WaitGroup, predictable across all call sites.

AX Principle 2 — comments must show HOW with real values, not describe

AX Principle 2: comments that restate the type signature add zero

PingPeer, ConnectToPeer, and DisconnectFromPeer had comments that
restated the signature in prose. AX-2 requires concrete call examples,
not descriptions. Replaced all three with usage-example comments.

AX Principle 2: comments as usage examples, not restatements of the
signature. "Count returns the number of registered peers." says nothing

AX Principle 1 — predictable names over short names. `mu` and `wg` require

AX Principle 1 — predictable names over short names.

AX Principle #1: names must not require a comment to explain.
The comment "Calculate round-trip time" existed solely to decode
the abbreviation rtt — proof the name was too short.

geo is an abbreviation that requires domain knowledge to parse;
geographicWeight makes the dimension self-describing.

AX Principle 1 — predictable names over short names. idx is an

Single-letter v is not AX-exempt — only i (index) is allowed in range loops.
The element variable names the thing being iterated, so: supported.

- Updated `Worker.handleDeploy` to handle STIM bundles using `ExtractProfileBundle` and `ExtractMinerBundle`.
- Used `PeerConnection.SharedSecret` as the password for decryption.
- Implemented logic for `BundleProfile`, `BundleMiner`, and `BundleFull`.
- Fixed broken files `pkg/node/dispatcher.go` and `pkg/node/peer.go` to ensure compilation and testing.
- Updated tests in `pkg/node/worker_test.go` and added coverage for deployment logic.
This commit introduces a new audit document, `AUDIT-ERROR-HANDLING.md`, which provides a comprehensive review of the project's error handling and logging practices.
The audit covers:
- **Error Handling:** Analyzes the inconsistency between the well-structured API error responses and the simpler, unstructured error handling at the application's entry points.
- **Logging:** Details the existing custom logger, its lack of JSON output, and its inconsistent use across the codebase.
- **Recommendations:** Provides actionable steps for improvement, including adopting structured JSON logging, centralizing logger configuration, and standardizing on the global logger.
This commit also includes fixes for pre-existing build errors to allow the CI to pass:
- Adds a missing package declaration and imports in `pkg/node/dispatcher.go` and comments out calls to undefined methods.
- Adds a missing import in `pkg/node/peer.go` and resolves an unused variable error.
- Removes an unused import in `pkg/ueps/packet.go`.

- Add GenerateChallenge() for random 32-byte challenge generation
- Add SignChallenge() using HMAC-SHA256 with shared secret
- Add VerifyChallenge() with constant-time comparison
- Update performHandshake() to send challenge and verify response
- Update handleWSUpgrade() to sign incoming challenges
- Add comprehensive tests for challenge-response flow
The challenge-response authentication proves the peer has the matching
private key for their public key by signing a random challenge with
the ECDH-derived shared secret. This prevents impersonation attacks.

Add PeerAuthMode to control peer registration:
- PeerAuthOpen: Allow all peers (backward compatible default)
- PeerAuthAllowlist: Only allow pre-registered peers or allowlisted public keys
New features:
- PeerRegistry.SetAuthMode/GetAuthMode for mode control
- PeerRegistry.AllowPublicKey/RevokePublicKey for key management
- PeerRegistry.IsPeerAllowed check before connection acceptance
- Transport rejects unauthorized peers with proper handshake rejection
New API endpoints:
- GET/PUT /peers/auth/mode - Get/set authentication mode
- GET/POST/DELETE /peers/auth/allowlist - Manage allowlisted keys
