ValidateCode for tokens refused as sessions. Do not replace it with another
unbounded hot-path log; use a bounded metric or sampled diagnostic only if

1. Rejected sessions write to the console 📘 Rule violation ➹ Performance
The new refusal branch in ValidateCode calls Console.WriteLine instead of a warning-level logger when IsEcencySession returns false. Private-api handlers invoke this validator while handling requests, so a client sending a token for another app causes a synchronous console write on the request path.
Agent Prompt
## Issue description
The new session-refusal branch writes directly to the console during request handling.
## Fix Focus Areas
- dotnet/EcencyApi/Handlers/PrivateApi.Core.cs[130-136]
## Recommended Fix
Replace the console write with a warning-level logger call while retaining the sanitized app and type labels.

Addressed in 932fc62, same as the CodeRabbit thread: the write happens at most once per kind of refusal and 32 lines per process, not per request. This service logs through the console everywhere, so it stays consistent with that.

2. Session denials lack endpoint coverage 📘 Rule violation ▣ Testability
The new IsEcencySession check changes the authentication result used by private-api handlers, but the new tests call ValidateCode directly and no endpoint-specific divergence was added to dotnet/parity/driver.py. For a signed token issued to another app, handlers such as Activities now receive null and return a 401 response without a matching HTTP test or parity entry.
Agent Prompt
## Issue description
The shared session check changes HTTP-visible denials without endpoint-level tests or a parity divergence entry.
## Fix Focus Areas
- dotnet/EcencyApi/Handlers/PrivateApi.Core.cs[125-136]
- dotnet/EcencyApi.Tests/SessionTokenTests.cs[83-99]
- dotnet/parity/driver.py[273-285]
## Recommended Fix
Add an HTTP-level test for an affected private endpoint using a signed token from another app, and document that endpoint's changed behavior relative to the reference in the parity divergences.

No parity entry needed. The harness only sends invalid codes (invalid, badcode), and those are refused identically before and after this change. No catalogued case sends a correctly signed token, so no response diverges. The new rule is covered by SessionTokenTests with real signatures.
A refused or malformed token is logged the first time its kind is seen, at most 32 lines per process, so request paths stay quiet.

Private-api sessions now accept only the tokens Ecency's own clients send: a message issued to the
ecency.appHiveSigner app, typedcodeorposting. Any other signed message is refused before any node lookup.Checked against every first-party sender: web (HiveSigner, Keychain, Hive Keeper, key and wallet logins, all exchanged for a posting token), mobile (key, in-app HiveSigner, HiveAuth), and Ecency Waves (self-signed
codetokens and HiveSigner tokens). All of them keep working.Also:
appandtypelabels, so a client locked out by this is visible in the logs.Tests:
SessionTokenTestsuses real signatures. The full suite passes (601).Summary by CodeRabbit
codeandpostingtokens issued to the Ecency app. Tokens from other apps, login proofs, and messages without an accepted type are rejected before account lookup.codeandpostingtokens continue to work as sessions, including posting tokens signed through HiveSigner.
