fix(replay): isolate retained reasoning state by admitted caller (carry #7523) - #7566
Conversation
#7523) Scope retained reasoning state to the admitted caller and conversation. Plaintext replay additionally requires the exact physical provider identity. Native Chat, native Combo children, bridge Combo candidates and Responses compaction carry the same principal; bridge candidates receive a trusted internal holder captured before provisional caller credentials are stripped. Opaque serving metadata and rejection memos use separate caller namespaces. Carried onto current dev from #7523 (head f27d3c2). Co-authored-by: Epinephrine <luvs01@hanmail.net>

…ntials The Chat Completions bridge, Claude Messages and the routed Responses compaction handoff rebuild an internal Request that omits the caller's OCX credential (Authorization is stripped on combo/policy routes and on every Messages request; x-opencodex-api-key is never forwarded). On loopback the principal was then resolved from that sanitized request, so a key-volunteering caller silently lost its own retained reasoning. Resolve the principal from the admitted client request and pass it as the internal replayPrincipal holder, as bridge Combo children already do. Co-authored-by: Epinephrine <luvs01@hanmail.net>

The translated internal request may still carry forwarded or stored upstream authorization; what it may lack is the caller's opencodex key. State that the principal is resolved from the admitted original request and handed over through handleResponses options. Build the regression's synthetic bearer values from fixture config so the privacy scan passes. Co-authored-by: Epinephrine <luvs01@hanmail.net>

Synced this branch with Focused integration validation: 132 pass / 1 inventory failure. Sparse checkout omitted an existing inventory document; restoring that exact HEAD file made the affected check pass (1 pass / 0 fail). TypeScript, structure, privacy and file-size ratchet passed. The inherited EOF blank-line warning in Automatic hosted CI for the new HEAD is pending. No full Windows suite or live-provider validation is claimed. Explicit maintainer security review remains required before merge. |

Summary
Carry of #7523 by @luvs01 onto current
dev(9164950d92, after #7549 changedcore-combo.ts). The first commit is the original PR headf27d3c23cbunchanged, except for one conflict line inscripts/test-layout/layout.json. The second commit fixes a review finding on this PR: translated ingresses lost the caller principal (see below).Retained reasoning state is now scoped to the admitted caller and conversation. Before this change, two callers that sent the same conversation identifier to the same provider shared retained plaintext reasoning, opaque serving metadata, and rejection memos. After it:

Before this, a bearer-only loopback caller lost access to its own retained reasoning whenever it was routed through a bridge combo, on both the first candidate and failover.Cache limits, expiry, provider authorization, and Google's durable signature handling are unchanged.

This change touches the caller identity boundary for retained reasoning state. It is limited to what this diff shows:
resolveContextPrincipal) in addition to conversation and physical provider identity. Keyless requests cannot store or read principal-scoped plaintext.x-opencodex-client-principal-id,replayPrincipal,_reasoningReplayScope) are not trusted, and the regression test asserts that they do not unlock another caller's plaintext.Authorizationis still removed from combo child requests and is never sent upstream; upstream calls use only provider row credentials (asserted in the test).Verification
