Review comments at @src/server/responses/core-combo.ts:
- Around line 466-472: In executeComboResponses, resolve the principal once
before bridge child headers remove authorization, then pass it through the child
options to handleResponses. Update the child options type and request-prepare
principal resolution to use the passed principal when available, falling back to
resolveContextPrincipal otherwise, so bridge retries retain the caller-scoped
replay identity.
Review comments at @structure/transports/native-reasoning-retention.md:
- Around line 19-22: Clarify the keyless memo contract in this passage: keyless
callers share a principal namespace, but serving and rejection memos must still
compare physical identity where required. Keep this physical-identity binding
distinct from plaintext-cache authorization.

Functional review at b1cf901bc47d7b0c42588252189d6857edb5f685: the new principal-scoped plaintext cache and separate opaque-memo namespaces have useful focused coverage, but the bridge child can still lose the principal established by its parent.
src/server/responses/core-combo.ts:469 resolves the parent principal from the original request for eligibility. At lines 896/998 onward, buildComboChildHeaders strips authorization and the bridge calls handleResponses with the original loopback admission, without a resolved trusted principal. request-prepare.ts:604 then resolves from the stripped request and overwrites the child replay scope with an absent principal. The native child path separately carries admission, so its new regression does not cover this bridge path.
I independently exercised the real header builder and principal resolver with a configured synthetic OCX key sent only as Bearer on loopback: parent principal present; child Authorization absent; child principal absent. Combined with the child call and scope rewrite above, the same caller loses access to its retained plaintext reasoning when routed through a bridge combo; another candidate repeats that loss. This is a functional loss of valid replay, not evidence of cross-caller disclosure.
Please resolve caller identity before removing the provisional credential, preserve that admitted principal in trusted internal child state, and use it consistently in bridge request preparation. Do not restore caller Authorization as an upstream credential or accept an identity asserted by a client header. Add a real bridge-combo regression using loopback + bearer-only OCX admission, including a second candidate/failover and cross-caller/keyless controls. The existing review concern about the keyless physical-identity documentation also remains worth clarifying.
Independent Bun 1.4.3 / Linux, isolated homes and hard cgroup limits: 114 passed / 0 failed, 719 assertions across reasoning-replay-identity, responses-replay-metadata-principal, chat-native-combo, chat-native-reasoning-replay, chat-native-reasoning-scope and responses-anthropic-thinking-recovery. This focused pass does not exercise the missing bridge regression, prove native platforms, or constitute the separate explicit security-boundary acceptance. Current-head required CI and outstanding reviews remain separate gates.

Addressed in Bridge Combo candidates now receive a trusted internal replay-principal holder captured before provisional credentials are stripped. Explicitly keyless identity is preserved too. Caller Authorization is still removed, and client-supplied identity headers/body fields cannot populate this holder. The new real-handler regression covers both the first candidate and a 404-to-second-candidate failover. The identical tests failed before the fix and now pass (2 tests, 106 assertions), including foreign/keyless spoof controls, provider-only outbound credentials and parent send/completion accounting. Related compatibility coverage passed 113 tests / 1,123 assertions. Typecheck, structure, privacy, layout and size gates passed; independent source review found no blocker. The keyless documentation now separates the shared principal namespace from physical-identity comparisons. Current-head hosted CI is pending; the earlier successful |

The bridge-principal follow-up is ready for re-review at The preceding run exposed a test setup dependency on a missing repository The verification section is updated and the PR is ready for review. This does not dismiss the outstanding review or claim the separate security-boundary acceptance, native-platform acceptance or live-provider validation. |

#7523) (#7566) Carries #7523 onto current dev: retained plaintext reasoning is bound to the admitted caller principal, including bridge combo children and 404 failover; unknown principals fail closed.

Summary
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 retries and Responses compaction consistently carry that principal. Bridge children use a trusted internal identity holder after provisional caller credentials are removed. Opaque serving metadata and rejection memos now use separate caller namespaces too, so a shared conversation identifier does not mix callers' route-change or recovery decisions.
Preserve keyless physical-identity safeguards, per-blob ownership checks and Google's durable signature handling. Keyless requests cannot capture or retrieve principal-scoped plaintext. Cache limits and expiry remain shared; this change does not alter provider authorization or make retained ciphertext portable across accounts. Combo children receive admission without taking ownership of parent logging, send accounting or leases.
Verification
5bdd28edc2802679e5455b6d1fe164bb9729f52apassed 353 focused tests plus 96 follow-up fixture tests, and hosted CI passed all four test shards and gates. Those results are historical coverage, not current-head CI proof.f27d3c23cb13310b93a55d51fdd56405bb5d3459; hosted CI 39803356181 completed successfully on this head: all four test shards and required gates passed (14 successful jobs, 9 conditional skips). Skipped platform jobs are not counted as native acceptance. The3cee873run exposed a fixture setup error before the new test body: a fresh checkout had no repository.tmpparent. The fixture now uses the OS temporary directory and safely handles failed setup; the same two tests still pass with 106 assertions. Product code, assertions and timeouts are unchanged by this fixture correction. Earlier CI 39790103725 passed onb1cf901, not this head. Full local tests were not repeated under the resource exception because concurrent worktrees share the queue and storage is limited. Native platform and live provider behavior remain outside this validation.Focused follow-up commands used the pinned binary directly:
