fix(codex): emit modern env_key admission line on non-loopback inject - #2076
Conversation
codex-cli 0.146+ documents env_key as the bearer auth form for custom model providers: it sends Authorization: Bearer $VAR and hard-errors on a missing variable instead of silently omitting the header. The server side already admits and substitutes this bearer (#1686 chain), so the injector was the stale half. Loopback Design B still emits no auth line; the #2061 orphan sub-table cleanup keeps handling historic env_http_headers configs. Closes #2073

targets.
- Around line 39-43: Update the reviewer verdict contract so MERGE-OK includes
the exact reviewed PR headRefOid, and have the merge flow compare that SHA with
the current PR head immediately before the admin merge. If the SHA differs,
reject the verdict and rerun the review before merging.

Classify post-merge CI before continuing a merge batch.
The plan schedules multiple admin merges, but it does not require the previous merge's CI result to be classified before the next merge. If a later commit depends on a failed merge, reverting “that one merge” may be unsafe.
Require this sequence: one merge, post-merge CI classification, then the next merge. Otherwise, define and test a rollback procedure for batched merges.

Bound the known-red Windows CI exception.
The plan excludes the Windows dispatch leg based only on “known-red.” It does not identify the baseline run, failing test fingerprints, or a no-new-failures rule. A new Windows regression could therefore be classified as pre-existing.
Record the baseline SHA or run, allow only the known failure set, and escalate when the failure set changes. Apply the same evidence to the pre-existing-red classification at Line [35].

Tie proxy authentication to the bind hostname.
The manager guidance must state that x-opencodex-api-key is required only when OpenCodex uses a non-loopback bind. A manager may still dial http://127.0.0.1:10100/v1 while the proxy listens on a wildcard or other non-loopback hostname. Loopback-only binds require no authentication. Keep env_key = "OPENCODEX_API_AUTH_TOKEN" for generated non-loopback Codex providers.

Update the authentication explanation to match env_key.
The sample now uses env_key, which makes Codex send Authorization: Bearer .... The surrounding text still explains the removed x-opencodex-api-key environment-header form. State that the non-loopback provider requires the provider-level env_key field, and keep legacy or external-provider-manager header forwarding separate.
