Conversation
📝 WalkthroughWalkthroughThe change adds opt-in structural diagnostics for adapter and bridge streams. It records event metadata, byte counts, fingerprints, sequence numbers, attempt ordinals, and recovery kinds while excluding raw content. The Responses, image, web-search, and terminal-continuation paths share this diagnostic context. ChangesStructural diagnostic primitives

Merge Risk: 🔵 Low · up to The new diagnostics need clearer privacy limits, and account or key rotation can make their adapter labels inconsistent. This is debug-only observability risk, but should be corrected for reliable operator use. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Document the complete privacy boundary.
Line 176 omits raw credentials, account IDs, and request bodies from the exclusion list. It also does not state that diagnostics are observation-only. Add these limits here, or link to the canonical provider-debug policy.
As per path instructions, provider debug documentation must describe opt-in, structural, observation-only diagnostics and exclude raw credentials, account IDs, and request bodies.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Resolve the adapterName label lazily for runTurn diagnostics.
When refreshRunTurnSelection() replaces runTurnAdapter before the queue emits events, diagnoseAdapterEvents() still uses the name captured at src/server/responses/core.ts:6871 and :6877-6879. The bridge stage reads the updated diagnosticContext.adapterName in src/bridge.ts:1022, so both stages can report different adapter names for the same event. Resolve the name when each event is consumed.
🔧 Proposed fix
function diagnoseAdapterEvents(
events: AsyncIterable<AdapterEvent>,
- adapterName: string,
+ adapterName: string | (() => string),
requestId: string | undefined,
logCtx: RequestLogContext,
state: BridgeDiagnosticSequence,
): AsyncIterable<AdapterEvent> {
if (!requestId) return events;
return (async function* () {
for await (const event of events) {
const attempt = logCtx.activeAttempt;
+ const resolvedAdapterName = typeof adapterName === "function" ? adapterName() : adapterName;
debugStreamDiagnostic(
{
requestId,
- adapterName,
+ adapterName: resolvedAdapterName,
...(attempt?.ordinal !== undefined ? { attempt: attempt.ordinal } : {}),
...(attempt?.recoveryKinds.at(-1) !== undefined ? { recovery: attempt.recoveryKinds.at(-1) } : {}),
},
"adapter",
++state.value,
event.type,
adapterEventDiagnosticDetails(event),
);
yield event;
}
})();
}Pass () => runTurnAdapter.name at both runTurn call sites.

Summary
Extract the stream diagnostics slice from the closed oversized #2516 proposal. Opt-in debug lines correlate adapter and bridge stages, attempts, and sidecar rounds. Payload text, reasoning, tool identifiers, arguments, queries, and error strings become lengths and process-local HMAC fingerprints; raw content and provider state are excluded. This is separate from the local telemetry ledger in #3748.
Updated CLI debug documentation. Maintainer privacy/security review remains required before advancing this draft.
Verification
Root
bun run typecheck,bun run privacy:scan, and the core/Lab boundary tests passed. Five focused files combined: 180 passed, two web-search failures; unchanged upstream runtime reproduces those same two failures (172 passed). The web-search file alone passes all 62 tests. Documentation frozen install and build passed. Static privacy review covered field selection, random request ids, debug gating, and the process-local random HMAC key.All runtime checks used a fresh temporary OPENCODEX_HOME and alternate port; production config fingerprint and backup inventory remained unchanged. Full root-suite and review-readiness gates have not been completed for this head; this is intentionally a draft.
