fix(codex): remove injected routing and restore the routed catalog after a Codex app rewrite - #1862
Conversation
…ig.toml #1798. When the Codex app rewrites config.toml after injection, the journal's exact-bytes restore stops matching and the fallback strip is all that is left. That fallback recognized an injected `openai_base_url` only by the marker COMMENT on the preceding line -- and a reserializing app writer keeps every value while dropping every comment. So the proxy URL stopped being recognized as ours, `removeCodexConfig` reported "opencodex not present in Codex config", and plain Codex was left pointing at a dead 127.0.0.1:10100. The marker was formatting evidence for an ownership question. Record the value instead: `markJournalInjectedState` now stores the exact root `openai_base_url` the injection wrote, and the fallback strips a root URL whose value equals it. The match is deliberately exact rather than "any loopback-looking URL". Stripping by shape would delete a gateway the user configured themselves, which is why `hasInjectedOpenaiBaseUrl` was conservative in the first place; keying on what we recorded writing keeps that guarantee while surviving the rewrite. Verification: new `tests/codex-restore-app-rewrite.test.ts` injects, reserializes the config exactly as an app writer does (values kept, comments dropped), then restores. Driven red by pinning the journal accessor to null, which reproduces the issue's surviving `127.0.0.1:10100` line. Its second case covers the mirror-image risk: a user's own pre-injection `openai_base_url` still survives restore. `bun x tsc --noEmit` clean; 68 tests green across journal, inject, catalog-restore, and CLI restore suites. Not addressed here: the `models_cache.json` half of the issue. Catalog restore re-resolves its target from the post-rewrite TOML, so a config that dropped `model_catalog_json` never reaches the proxy-written cache. That needs the injected catalog path threaded through restore and is left for its own change.

When config.toml already contains an unmarked root openai_base_url, setRootOpenaiBaseUrl deliberately preserves it, but this assignment nevertheless records that user-owned value as injected. If Codex later reserializes the file differently or the user edits any other setting, the journal hash no longer matches and stripJournaledOpenaiBaseUrl deletes the user's gateway because its value matches this record. Record null unless the transform actually inserted or owned the URL, and cover the fallback path with a pre-existing URL plus an unrelated edit.

When routing is reinjected while the existing journal remains—for example, after changing the proxy port or hostname—the config receives the new URL, but the injectedConfigHash guard above causes this new field to retain the first injection's URL. If the Codex app then drops the marker comment, fallback restore compares against the stale value and leaves the latest proxy URL in place, so plain Codex still targets a stopped endpoint. Refresh the injected-URL evidence on every successful reinjection without replacing the original snapshot.

…nfig now names The second half of #1798. Catalog restore resolved its target with `readCodexCatalogPath()`, which re-reads `model_catalog_json` from the CURRENT config. After a Codex app rewrite drops that key, restore walks to the default catalog while the routed `models_cache.json` we really wrote keeps every `provider/slug` entry -- which is why the model picker still listed routed models after `ocx restore` reported success. Record the injected catalog path in the journal and pass it to `restoreCodexCatalogWithPermit` as an explicit target, falling back to today's resolution when nothing was recorded. The capture has to happen in the CALLER, before the config half runs: a successful journal restore deletes the journal and a config restore can remove `model_catalog_json`, so reading it inside the catalog step would be too late in both directions. Both restore entry points capture it up front. Verification: a third case in tests/codex-restore-app-rewrite.test.ts injects with an explicit cache path, drops `model_catalog_json` the way a rewrite does, and asserts the routed entries are gone from that exact file. Driven red by pinning the resolution back to `readCodexCatalogPath()`, which leaves `opencode-go/deepseek-v4-flash` in place. 69 tests green across the journal, inject, catalog-restore and CLI restore suites; `bun x tsc --noEmit` clean.

Summary
Fixes both halves of #1798.
Config half. When the Codex app rewrites
config.tomlafter injection, the journal's exact-bytes restore stops matching and the fallback strip is all that is left. That fallback recognized an injectedopenai_base_urlonly by the marker comment on the preceding line — and a reserializing app writer keeps every value while dropping every comment. The proxy URL therefore stopped being recognized as ours,removeCodexConfigreportedopencodex not present in Codex config, and plain Codex was left pointing at a dead127.0.0.1:10100.The marker was formatting evidence being used to answer an ownership question. This records the value instead:
markJournalInjectedStatestores the exact rootopenai_base_urlthe injection wrote, and the fallback strips a root URL whose value equals it. The match is deliberately exact rather than "any loopback-looking URL" — stripping by shape would delete a gateway the user configured themselves, which is whyhasInjectedOpenaiBaseUrlwas conservative to begin with.Catalog half.
restoreCodexCatalogWithPermitresolved its target withreadCodexCatalogPath(), which re-readsmodel_catalog_jsonfrom the current config. Once the rewrite dropped that key, restore walked to the default catalog while the routedmodels_cache.jsonwe actually wrote kept everyprovider/slugentry — the reported symptom of the picker still listing routed models after a successful-looking restore. The injected catalog path is now journaled and passed in as an explicit target.That capture happens in the caller, before the config half runs: a successful journal restore deletes the journal, and a config restore can remove
model_catalog_json, so reading it inside the catalog step would be too late in both directions.Failure path being closed:

devbun x tsc --noEmitcleanNotes for review
Two corrections the investigation forced on the original plan, recorded in
devlog/_plan/260816_wave34_closeout/102_1798_restore_merge.md:sha256of the injected state. That would need a new journal version; the defect does not require one.openai_base_url. Value-matching against what we recorded writing achieves the same removal without that risk.The third reported symptom —
ocx stopleaving the CLI autostart shim installed, so the nextcodexinvocation re-injects — is a separate lifecycle question and is not addressed here.Summary by CodeRabbit
