fix(server): managed Codex renews the token its model catalog uses - #33713
Managed Codex launched with refresh_interval_ms=0 on its token-helper auth. In the pinned Codex 0.166.0 that value disables proactive refresh: the app-server reuses the token it fetched first for as long as the process runs, and only the Responses path re-runs the helper after a 401. The model-catalog request (/v1/models) has no 401 recovery, so once the launch token expires every catalog refresh in that process fails with 401, and new threads fall back to generic model metadata (258k window, no tool search, ~230k-token startup) and compact after nearly every tool call.
Reproduced with the real Codex 0.166.0 app-server binary, launched with T3's managed provider arguments pointed at a local fake API and a helper that prints a rotating token: after the token rotates, the app-server's scheduled catalog refresh keeps sending the old token and gets 401, logging failed to refresh available models: unexpected status 401 Unauthorized: Unknown error, the error in the report.
Change
Managed Codex now launches with refresh_interval_ms=60000. Codex then re-runs T3's token helper on its next request once its cached token is a minute old, so every request, the catalog included, picks up a renewed token within a minute. The broker's renewal margin moves from 60 s to 90 s (TOKEN_RENEWAL_MARGIN_MS = TOKEN_REFRESH_INTERVAL_MS + 30_000), so a token Codex caches is renewed before it can expire, with room for helper latency. The helper only reads the saved token over the local socket unless a renewal is due.
CodexManagedRuntime.test.ts: the existing launch-arguments case now requires refresh_interval_ms to be positive and shorter than the broker's renewal margin. On main all four rows (managed/local × primary/additional) fail: refresh_interval_ms=0 must be in (0, 90000): 0 makes Codex reuse the launch token forever for model catalog requests…. With the fix they pass.
CodexChatGptAuth.test.ts: the existing concurrent-access renewal case now leaves 75 s on the token instead of an expired one; it fails with the old 60 s threshold (expected +0 to equal 1) and passes with the 90 s margin.
Runtime check with the real Codex 0.166.0 app-server (Linux x64), T3's managed provider arguments with the base and catalog URLs pointed at a local fake API that accepts only the current token, and a helper that prints a token file rotated 30 s after launch. Synthetic tokens only, no OpenAI calls. The only difference between runs is refresh_interval_ms:

T+ 30.0s rotated: helper now prints token-B; token-A is expired

No visible surface changes, so there are no captures. Not checked: a real ChatGPT sign-in across a full token lifetime, and macOS and Windows (the change is a launch argument and the helper path is the one already in use).
AI-assisted; verified with the tests and tools listed above.
The managed provider launches Codex with refresh_interval_ms=0, so a running
app-server reuses its launch token for model catalog requests after it
expires. Assert a positive interval within the broker's 60s renewal margin.

T3 launched managed Codex with refresh_interval_ms=0 for the token helper.
Codex treats 0 as "never refresh proactively": it keeps the first token and
asks the helper again only after a 401 on the Responses path. The model
catalog request has no such retry, so once the launch token expired every
catalog refetch in that app-server failed with 401. New sessions then fell
back to generic model metadata.
Codex now re-runs the helper every 60 seconds. The broker already renews a
saved token once it has 60 seconds or less left, so a token Codex holds for
at most 60 seconds is never used past its expiry. Both sides now read the
same TOKEN_RENEWAL_MARGIN_MS constant so the two values cannot drift.
Fixes#33701

Macroscope's review found this PR requires human approval — Managed Codex will refresh cached helper tokens after one minute and renew credentials earlier to prevent stale model-catalog authentication. This changes the default behavior for managed sessions and requires human review despite the reported successful runtime verification.
Notes:
All code in this push has already been reviewed. Approvability was decided on eligibility alone.
You can add or adjust custom eligibility rules. Learn more.
The managed Codex runtime now uses a 60-second token refresh interval. The credential renewal check uses a 90-second margin, calculated from that interval plus 30 seconds.

Layer / File(s)
Summary
Define and configure refresh timing apps/server/src/provider/CodexManagedTokenProtocol.ts, apps/server/src/provider/CodexManagedRuntime.ts, apps/server/src/provider/CodexManagedRuntime.test.ts
The protocol exports a 60-second refresh interval and a 90-second renewal margin. The managed runtime uses the refresh interval. The test checks that the configured interval is greater than zero and less than the renewal margin.
Apply the renewal margin apps/server/src/provider/CodexChatGptAuth.ts, apps/server/src/provider/CodexChatGptAuth.test.ts
The access-token renewal check compares remaining token lifetime against the shared 90-second margin instead of a fixed 60-second threshold. The test advances the clock to leave 75 seconds on the one-hour token before concurrent access requests.

Explanation
Issue #33701 requires managed Codex catalog requests to stop reusing an expired launch token. CodexManagedRuntime.ts now sets refresh_interval_ms to TOKEN_REFRESH_INTERVAL_MS (60,000 ms). CodexChatGptAuth.ts uses a 90,000 ms renewal margin. The tests check the launch interval and renewal inside that margin. The PR reports a Codex 0.166.0 runtime check where the catalog request uses the rotated token. No coding requirement remains unmet.

Codex reuses a helper token for up to its refresh interval, so the broker
must renew earlier than that. Equal values left no room for helper
latency; the broker now renews 30 s before the interval would run out.

Bound the refresh interval independently of the renewal margin.
The assertion also passes for a 30-minute interval because the margin grows with it. A 20-minute token accepted by the authentication schema can then expire before Codex refreshes it.

Additional macOS confirmation with Codex 0.167.0: logs show catalog 401s and unknown-model fallback. One affected Astra session compacted 62 times, with normal post-compaction requests still around 232K tokens.
An isolated test holding 300 synthetic MCP tools constant found that changing only supports_search_tool from true to false expanded tool definitions from 18,669 to 230,162 JSON characters. This corroborates the context-expansion mechanism.
Switching T3 to an existing ChatGPT-authenticated Codex installation restored normal startup: 29,639 input tokens, a 475K effective window and no compaction. This verifies the workaround, not this PR across real token expiry.
