Review-finding disposition for this carried PR (the diff is byte-identical to the original #4025 head 6c1387d; see the carry note above):
|
The startup binding restoration reads the pinned owned auth path inside the native owner claim; an unbounded readFileSync there can block on a replaced non-regular file (e.g. a FIFO) or exhaust memory on an oversized one. Opt the new observation path into the existing native-profile bounded reader (regular file, 4 MiB cap, no-follow, non-blocking) and classify bounded violations as unreadable: no binding is created and a prior verified binding is retained. Legacy readCodexTokensResult callers keep the unbounded read. A child-process regression covers valid, FIFO (POSIX), symlink (POSIX), oversize, directory, and missing files, including binding retention across a failed re-read; the FIFO cases double as hang detectors through the spawn timeout. Review-finding correction on the carried #4025 (maintainer commit).

…oken extractAccountId returns the first supported claim, so a token whose top-level and namespaced chatgpt_account_id encodings disagree could pass the startup binding's identity-agreement check. extractAccountIdClaims now reports that conflict (the two account-id encodings only; organizations entries are workspace memberships, never identity) and the binding refuses it, while opaque bearers keep the explicit-account fallback. A new harness scenario drives the rejected binding end to end, claim-pair cases pin the extractor, and the oversize fixture becomes parseable so only the size cap keeps it unbound. Review-finding correction on the carried #4025 (maintainer commit).
…startup read The two locale pages listed only Direct and main-fallback, while the account-policy invariant and the code fence exact-main and main-pin as well, and stored Pool accounts stay eligible for the whole pending window. Both pages now match structure/08. policyReadsPinned asserted that every recorded read used the pinned path, which an empty read list satisfies, so it could not show that an owned startup read anything. Owned scenarios now also assert at least one read; foreign and unknown keep their zero-read assertion. Review-finding corrections on the carried #4025 (maintainer commit).

Reviewed the runtime and regression delta at 87efd10.
The startup binding is made from the pinned owned auth path only after recovery/stage cleanup and an exclusive claim. The independent access/id-token agreement checks avoid assigning a saved main policy to a conflicting identity; a failed read retains a previously verified same-process binding. I checked the positive 98%/99% admission cases, foreign/unknown ownership, manual recovery, listener rearm, stale stage-sweep, and the bounded-reader controls. The FIFO/symlink fixtures are meaningful because their valid payload would otherwise bind, rather than merely fail JSON parsing.
The new caller-owned admission fence does not require reading a foreign home, and stored Pool alternatives remain available. I found no additional source blocker.
Repository run 34338221921 passed at this exact head. Because this changes startup/ownership and filesystem admission, I am keeping the integration hold until there is final-head Windows coverage as well (the PR Windows test matrix was skipped). Please include that evidence in the cumulative stack run. I have not run this against the active local profile, and #4025 should remain the credited source rather than receive competing changes.

Summary
Carried from #4025 (author: @luvs01) to give the change a maintainer-sponsored same-repo head; the original fork PR is intake-blocked on
unsponsored_surface, an intake-hygiene gate rather than a product failure. Source commits: 9e632f6, 3edfb45, 6c1387d (original head 6c1387d). This diff is the original change rebased onto currentdevwith no semantic edits.After a restart, a persisted main-account 99% quota snapshot can remain hidden because its process-local identity and credential binding have not been rebuilt. A caller-owned Direct request then reaches upstream even after owned startup reports ready.
Restore the binding from the pinned native auth path under the native owner and exclusive claim, after recovery and stage cleanup and before publishing ready. The same transition handles successful cleanup retries, explicit recovery, and another listener using the existing lifecycle. Duplicate completion joins an active startup, and older sweep results cannot overwrite its gate.
Caller-owned Direct, main fallback, and main-pin selection briefly return the existing 503 maintenance response while this initialization is active. Healthy stored Pool alternatives remain eligible. Foreign/unknown service homes introduce no credential read or ownership reprobe through caller-owned admission. With protection disabled, the additional credential read and claim are skipped. Malformed fields or conflicting identity claims create no new binding and do not become recovery exceptions. A previously verified same-process binding and its safety state remain until a valid replacement observation or confirmed account transition; rejected input alone cannot release a measured block.
The binding remains memory-only; no credential equality tag is persisted. English/Korean account references and the account-policy invariant document the startup behavior.
The initializer extracts the ID-token and access-token account identities separately and checks each present identity against the owned file's explicit account ID before changing observations. This prevents an ID token for A from masking an access token for B. Owned opaque bearers retain the existing explicit-account fallback; JWT decoding is not the source of ownership or credential authentication.

This is the bottom layer. The child PR's base is this branch; after this PR lands, the child is retargeted to
dev.Security review: this change touches authentication/credential handling (src/codex/auth-context.ts, src/codex/auth-collision.ts, src/codex/account-lifecycle.ts, src/codex/native-profile-startup.ts) and requires explicit security review per MAINTAINERS.md before merge.

Carry + review corrections (2026-09-09 update)
This branch was rebased onto dev 52ad823 and gained two maintainer corrective commits answering review findings on the carried change:
a79193fc0— the startup policy-binding read now uses the existing bounded native-profile reader (regular file, 4 MiB cap, no-follow, non-blocking) with bounded violations classified as unreadable; legacy callers keep the unbounded read. Child-process regression covers valid/FIFO/symlink/oversize/directory/missing, including binding retention across a failed re-read.11f575e33— a token whose twochatgpt_account_idencodings disagree is now rejected by the binding (extractAccountIdClaims; organizations entries are workspace memberships, not identity). Opaque bearers keep the explicit-account fallback.The three carried commits remain byte-exact cherry-picks of the original #4025 (author luvs01 preserved; the byte-fidelity proof covers the carried commits, not the corrective ones). Remote CI at the current head 11f575e: 25 checks pass, 2 dispatch-only skips, 0 fail (run https://github.com/lidge-jun/opencodex/actions/runs/34331710912), CodeRabbit review completed.
Review-thread closure (head 87efd10)
A third maintainer commit closes the remaining review findings:
providers-accountspages now name the complete fenced admission set — Direct, exact-main, main-fallback and main-pin — and state that healthy stored Pool accounts stay eligible for the whole pending window, matchingstructure/08_openai-provider-tiers.md.policyReadsPinnedasserted that every recorded read used the pinned path, which an empty read list satisfies. Owned startup scenarios now also assert at least one read happened, so the check can no longer pass vacuously. This doubles as evidence that the ESM read interceptor is live: were it dead, every owned scenario would fail rather than pass silently. All four Linux test shards are green at this head.Remote CI at 87efd10: 25 checks pass, 2 dispatch-only skips, 0 fail (run 34338221921). Local suite, typecheck and build: NOT RUN (local execution restricted in the preparing environment).
