2 actual failures (the rest are expected network errors in tests). Let me look at them:

  1. formatKnowledge > output === normalize(output) — likely a deterministic ordering issue
  2. LocalProvider integration > query and document embeddings have reasonable similarity — likely a network/model load issue

Interesting findings. Let me look at the key issues:

  1. OpenRouter 429s — expected for free models, being surfaced correctly
  2. OpenCode Zen 429s — free tier rate limit, expected
  3. OpenRouter 402 — credits exhausted, but note the worker is using the OpenRouter key for background tasks (should it?)
  4. MiniMaxapi.minimax.io/anthropic routing works correctly
  5. Anthropic batch auth error (401) — "invalid x-api-key" on batch API

The most concerning issue: the worker is sending requests through OpenRouter (line with worker upstream request failed: 402). The worker model should use the conversation's own provider, not route free-model sessions' worker tasks through OpenRouter where they'd cost money.

Several issues:

  1. Worker using OpenRouter credentials — The worker (distillation/curation) is reusing the session's OpenRouter auth to make background LLM calls. This costs money on the user's OpenRouter account for background work they didn't ask for, and fails with 402 when credits are low.

  2. MiniMax auth failure — Worker sends the MiniMax API key to what looks like a different endpoint expecting it in X-Api-Key header format, gets 401.

  3. "no auth credentials available for worker call" — After auth failures, the worker can't find valid credentials and spams warnings.

  4. Batch API using wrong key — Anthropic batch API gets 401 "invalid x-api-key", likely because it picked up a non-Anthropic session's credentials.

These are all pre-existing issues, not caused by our PR. The core problem: background workers (distillation, curation) inherit the session's auth credentials, which is wrong for non-Anthropic sessions. A MiniMax or OpenRouter key shouldn't be used for Lore's own background LLM calls.

These are deeper architectural issues that shouldn't block this PR. Should we:

  1. Merge this PR as-is and file issues for the worker auth problems?
  2. Fix the worker auth in this PR?

A MiniMax or OpenRouter key shouldn't be used for Lore's own background LLM calls.

Err no this should be the case? Whatever provider is being used for the session should dictate that session's worker provider and thus models.

What concerns me is the invalid key errors as all my keys are correct so there might be wrong credentials used on a provider issue. Moreover I keep seeing "early divergence at byte 10" errors showing a model change from opus-4-6 to minimax-m3 which I'm not sure is expected or not

gateway · 2026-06-05 21:09:10

You're right — the worker SHOULD use the session's provider. The issue is that the wrong credentials are being picked up. Let me dig deeper into those specific errors.

gateway · 2026-06-05 21:09:41

Now I see the full picture. There are two distinct issues:

1. Cache warmer cross-contamination: Session 1TjLgLHS3kg0Go98 alternates between claude-opus-4-6 and MiniMax-M3 on every turn. The prev body shows the model from the cache warmup request, and the curr is the actual user request. The cache warmer is sending warmup requests with the wrong model — it's warming with MiniMax-M3 on an Anthropic session and vice versa. This causes divergence at byte 10 (the "model" field).

This is because the lastUpstream snapshot (which includes model) is being shared/contaminated between sessions — or more likely, the cache warmer is reading from a stale or wrong session's snapshot.

2. Worker auth cross-contamination: The worker upstream auth error: 401 with "login fail: Please carry the API secret key" is MiniMax's error format. Then invalid x-api-key is Anthropic's format. Workers are picking up the wrong session's credentials.

Both point to the same root cause: the setLastSeenAuth() / resolveAuth() global fallback mechanism. When a MiniMax session sends a request, its API key becomes the lastSeenAuth. Then when an Anthropic session's worker needs auth, if the session-specific auth is stale, it falls back to lastSeenAuth — which is now the MiniMax key.

These are pre-existing issues (the global auth fallback was always there), but they're now more visible because the fetch interceptor correctly routes multiple providers simultaneously. Previously, all providers were forced through the gateway with the same baseURL override, so cross-contamination was masked.

These issues are beyond the scope of this PR (#577 fixes path normalization + free-model pricing). They need a deeper fix to the session-auth and cache-warmer architecture. Should I file them as separate issues and merge #577?

Now let me analyze the auth cross-contamination problem. The two issues from the logs:

  1. setLastSeenAuth() global fallback — when a MiniMax session sends a request, its API key becomes the global lastSeenAuth. When an Anthropic worker needs auth and the session-specific auth is stale, it falls back to this global value — which is now the MiniMax key.

  2. Cache warmer model cross-contamination — the lastUpstream snapshot alternates between MiniMax-M3 and claude-opus-4-6 on the same session, meaning the cache warmer warms with the wrong model.

Let me trace both issues in the code:

claude-opus-4-6 · 2026-06-05 21:15:41 · ~203 tokens

I need to understand how auth credentials and the lastUpstream snapshot get cross-contaminated between sessions in the Lore gateway.

The symptoms are:

  1. A MiniMax session's API key is used for Anthropic worker calls → 401
  2. Cache warmer alternates between MiniMax-M3 and claude-opus-4-6 model names for the same session (session 1TjLgLHS3kg0Go98)

Search for:

  1. In packages/gateway/src/auth.ts — find setLastSeenAuth(), getLastSeenAuth(), setSessionAuth(), getSessionAuth(), resolveAuth(). Understand how the global fallback works and whether it can cross-contaminate sessions.

  2. In packages/gateway/src/pipeline.ts — find where setLastSeenAuth() is called (it captures auth from every incoming request). Also find where extractAuth() is called and how auth flows from the incoming request to rawHeaders to session state.

  3. The cache warmer issue: in packages/gateway/src/cache-warmer.ts — find how it reads lastUpstream (or the old lastModel). The log shows session 1TjLgLHS3kg0Go98 alternating between MiniMax-M3 and claude-opus-4-6. This means lastUpstream.model is being overwritten by a different session's request. Check if the cache warmer shares state across sessions.

  4. In packages/gateway/src/pipeline.ts — check how sessionState.lastUpstream is captured. The postResponse section writes to sessionState.lastUpstream. Could there be a race condition where two sessions write to the same SessionState?

  5. Check session ID resolution — could two different OpenCode windows (one using Anthropic, one using MiniMax) resolve to the SAME session ID? Look at how x-lore-session-id is used and whether model switching within the same UI session (user picks a different provider mid-conversation) is the actual cause.

Return all relevant code with line numbers and your analysis of the root cause.

I'll systematically search through the codebase to trace the auth and session state flow. Let me start with all the key files.

Now let me check the fingerprintMessages function to understand whether two different sessions (Anthropic + MiniMax) could collide on fingerprint:

Now I have a thorough picture. Let me verify one more thing — does OpenCode send x-session-affinity and x-lore-session-id per conversation, or per OpenCode instance? And does switching models within OpenCode change the session header?

Now let me check a critical detail — does OpenCode use the same sessionID across model switches within a conversation, or does it create a new one? And what does the input.sessionID map to?

Now I have all the information needed to provide a comprehensive analysis. Let me verify one final detail — whether the lastSeenAuth global is really a single variable (not per-session), which is the crux of the auth contamination:

Now I have all the pieces. Here is the comprehensive analysis:


Analysis: Auth and lastUpstream Cross-Contamination Between Sessions

1. Auth Cross-Contamination

The Global Fallback Mechanism

File: /home/byk/Code/opencode-lore/packages/gateway/src/auth.ts

The auth system has two layers:

  • Per-session registry (sessionAuth Map, line 85): keyed by Lore session ID, stores the credential from each session's last request.
  • Global singleton (lastSeenAuth, line 135): a single AuthCredential variable, overwritten by every incoming request from any session.

The global is set in two places in pipeline.ts:

  1. Line 5294-5296 (handleRequest entry point) -- before session identification:

    const earlyAuth = extractAuth(req.rawHeaders);
    if (earlyAuth) {
      setLastSeenAuth(earlyAuth);  // GLOBAL — any session's key
    }
    
  2. Line 3613-3615 (handleConversationTurn) -- after session identification:

    const cred = extractAuth(req.rawHeaders);
    if (cred) {
      setLastSeenAuth(cred);  // GLOBAL — overwrites again
    }
    

The per-session credential is set at line 3689:

if (cred) {
  setSessionAuth(sessionID, cred);  // PER-SESSION — correct credential
}

How Cross-Contamination Happens

Under normal operation, resolveAuth(sessionID) at line 163-177 of auth.ts correctly returns the per-session credential first:

export function resolveAuth(sessionID?: string): AuthCredential | null {
  if (sessionID) {
    const cred = getSessionAuth(sessionID);
    if (cred && !staleSessionAuth.has(sessionID)) return cred;  // <-- happy path
    // ... ...
