Routed catalog rows are cloned from a native template, so they inherited supports_experimental_context from the account's native models. Codex reads that flag as "this model accepts experimental context history" and drives its context-management cadence from it, which on a routed third-party provider turns into a compact-after-every-step loop: a routed DeepSeek row compacted 1,600+ times in a single thread. Strip the field in normalizeRoutedCatalogEntry, next to the existing strips for supports_websockets and supports_reasoning_summaries. Validation: - bun run typecheck: clean - bun test tests/ci-workflows/file-size-ratchet.test.ts tests/e2e-style/phase100-native-parity.test.ts tests/codex-integration/codex-catalog.test.ts: 349 pass, 0 fail - bun run privacy:scan: pass - bun run structure:check: pass

…5073) The reset fixture in tests/server/server-auth.test.ts leaked its stream controller out of start() and errored it from the test body. Whether that rejection had a consumer depended on where Bun's server-side response sink happened to be: between its reads there is no pending read request to reject, so on a loaded runner the fixture's own error escaped as an unhandled error and failed the whole file. It fired on four unrelated heads (#4989, #5024, dev at ecd3ada, and #5085). Raise it from inside pull() on a stream whose high-water mark is zero instead. shouldCallPull is then true only while a read request is outstanding, so pull() runs if and only if a consumer is waiting for the next chunk, and throwing there rejects that read request. The reset now has a consumer no matter when the test calls it. What the code under test sees is unchanged: one SSE chunk, then a mid-stream body error. Closes #5073

Symptom
Codex Desktop compacted after nearly every step on a routed model. A single thread on a routed
DeepSeek row recorded 1,600+ compactions, while the account's native OpenAI models behaved
normally. Removing one catalog field from the routed row stopped it.
Cause
Routed catalog rows are cloned from a native template, so a routed row inherits
supports_experimental_contextfrom the native models the account exposes. Codex reads that flagas "this model accepts experimental context history" and drives its context-management cadence from
it. A third-party provider never negotiated that contract, so the cadence collapses into continuous
compaction.
normalizeRoutedCatalogEntryalready strips the sibling native-only selectors(
supports_websockets,supports_reasoning_summaries) for the same reason. This field was missed.Change
src/codex/catalog/parsing.ts: stripsupports_experimental_contextinnormalizeRoutedCatalogEntry.tests/e2e-style/phase100-native-parity.test.ts: the native template now carries the flag, andthe routed row built from it has to come out without it.
docs-site/src/content/docs/guides/model-routing.md: record the native-only flags a routed rowdoes not inherit, as AGENTS.md asks for a user-facing behavior change.
The strip is unconditional because nothing re-applies the field from provider metadata afterwards:
it is a native delivery contract, not a routed capability an operator opts into.
Validation
bun run typecheck-> clean.bun test tests/ci-workflows/file-size-ratchet.test.ts tests/e2e-style/phase100-native-parity.test.ts tests/codex-integration/codex-catalog.test.ts-> 349 pass, 0 fail.bun run test(full suite on macOS) -> 26,843 pass, 34 skip, 3 fail. The three are platform-only and unrelated to this change: the two Linux bubblewrap cases pass in isolation (parallel-load flake), and the Windowsicaclsspill-queue case reproduces identically on a cleandevcheckout.bun run privacy:scanandbun run structure:check-> pass.cd docs-site && bun install --frozen-lockfile && bun run build-> 465 pages built.Reproduced against
@bitkyc08/opencodex2.57.0 on macOS with Codex Desktop.devat 3d5efc7 still has no stripfor this field, so 2.58.0 and 2.59.0 carry it as well.
