P2 Badge Invalidate the main JWT plan when its token changes

After the first lookup, replacing auth.json with a refreshed token for the same ChatGPT account does not reset either mainAccountPlan or jwtPlanAttempted, because the identity reconciliation only purges state when the account ID changes. Consequently an upgrade or downgrade reflected in a new access token keeps returning the old plan until WHAM supplies an explicit plan or some unrelated reset occurs. Bind this cache to the observed token/account snapshot or invalidate it when the token file changes.

P2 Badge Prefer the current access-token plan over the ID token

When auth.json retains an older id_token while its refreshed access_token carries a new chatgpt_plan_type, this argument order makes extractChatgptPlanType return the stale ID-token plan immediately. That reproduces the stale-plan behavior for main accounts despite the live access token containing the correction. Inspect the access token first, using the ID token only as a fallback, or select the claim from the demonstrably newer token.

Invalidate the JWT-derived cache when token material changes.

Line 22 returns the prior JWT-derived plan indefinitely. Line 23 returns undefined indefinitely after one failed lookup. If auth.json changes between WHAM refreshes, this function does not decode the current token claim.

Track the token value or a token fingerprint with the derived cache. Preserve a fresh WHAM plan, but re-derive fallback data after the token changes. Add a regression test that replaces the token between two calls.

The PR objective requires current JWT evidence when WHAM has not supplied a fresh plan.

P2 Badge Read the JWT and generation from one credential snapshot

When another OpenCodex process replaces this credential between the two file reads, jwtPlanFromPoolCredential() can decode the old token while readCodexAccountRecord() returns the new generation. The resulting update then passes isCodexAccountGenerationLive and persists the old credential's plan as though it belonged to the replacement credential. Read one record and derive both credential.accessToken and generation from that same snapshot.

Preserve a fresh WHAM plan before writing a JWT fallback.

Line 59 overwrites every differing codexAccounts[].plan value. FreshPoolPlanUpdate has no WHAM source or freshness state. If WHAM has persisted team and a later token refresh has JWT claim pro, noteCodexAccountAccessToken can replace the authoritative WHAM value with pro.

Track plan provenance or fresh-WHAM state. Apply the JWT value only when WHAM has not supplied a current plan_type. Add a regression test for WHAM-first, JWT-refresh-second ordering.

P2 Badge Include credential generation in the applied-plan cache

If startup records plan pro here and a subsequent WHAM response overwrites the stored plan, a later credential refresh whose new JWT also says pro returns at this check without inspecting the new generation or current config. A request-triggered refresh with no ensuing WHAM probe therefore leaves the contradictory stored plan in place, defeating the newly added refresh reconciliation path. Key this cache by credential generation or suppress the update only after confirming the current configured plan still matches.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Add a startup-order regression test.

This changes startup behavior. The changed tests call reconcileCodexPlansFromTokens directly, but they do not verify that startServer reconciles plans before the first quota-prime request.

Add a flat Bun test that starts a pool-mode server with a stale stored plan and a JWT-derived plan. Assert that quota priming observes the reconciled plan before its first WHAM request.

As per path instructions, “A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem.”
