Problem

evaluateForecastAccount checks per-family rate-limit records with a hardwired family:

const rateLimitResetAt = getRateLimitResetTimeForFamily(account, now, "codex");

The forecast's --model never reaches the record check, and the runtime-overlay staleness cross-check inherits the same family. Two user-visible consequences:

  1. forecast --model gpt-5.6-sol reports ready for an account whose active record is under gpt-5.2 (the family that model belongs to) — while the runtime rotation proxy refuses every request for that family off the very same record.
  2. A persisted rate-limited overlay reason backed by a non-codex family record is cross-checked against the codex family, judged stale, and dropped — so the one surface that should have explained an outage instead reports the account healthy.

We hit this in production on 2026-08-15: a gpt-5.2 record on the pinned account had every session failing with codex_pinned_account_unavailable (148 requests, 9 successes on that proxy), while forecast --model gpt-5.6-sol showed both accounts ready with empty reasons.

Fix

ForecastAccountInput gains an optional family?: ModelFamily, defaulting to "codex" so model-less surfaces (status, fix) keep their exact current behavior. The three commands that already hold a model — forecast, best, report — resolve it via getModelProfile(model).promptFamily and pass it through. The overlay staleness cross-check becomes family-aware through the same value.

Tests

Three new cases in test/forecast.test.ts:

  • a gpt-5.2 record delays a gpt-5.2-family forecast (with the reset wait) and leaves a codex-family forecast ready;
  • a rate-limited overlay backed by a matching-family record is applied instead of dropped as stale;
  • the same overlay backed only by another family's record is still dropped.

Existing tests pass unchanged — they omit family and use codex-keyed records, so they now also pin the default's compatibility.

note: greptile review for oc-chatgpt-multi-auth. cite files like lib/foo.ts:123. confirm regression tests + windows concurrency/token redaction coverage.

Greptile Summary

this pr makes forecast availability and runtime-overlay validation use the requested model's family while preserving codex defaults for model-less callers.

  • threads prompt families through best, forecast, and report.
  • adds family-specific evaluator coverage for rate-limit records and overlays.
  • leaves command-level family threading without direct vitest assertions.

Confidence Score: 4/5

the pr appears safe to merge, with only non-blocking missing vitest coverage for the three command-level family handoffs.

the implementation consistently derives the family from each command's effective model and uses it for forecast gating; the remaining concern is regression protection around those command boundaries.

Filename Overview
lib/forecast.ts adds an optional model family and consistently applies it to rate-limit gating and overlay staleness checks.
lib/codex-manager/commands/best.ts passes the probe model's prompt family into forecasts, but this wiring lacks direct command-test coverage.
lib/codex-manager/commands/forecast.ts passes the requested model's normalized prompt family into forecasts, but this wiring lacks direct command-test coverage.
lib/codex-manager/commands/report.ts passes the inspected model's prompt family into report forecasts, but this wiring lacks direct command-test coverage.
test/forecast.test.ts covers matching-family gating and both matching and mismatched overlay records at the evaluator level.

### Issue 1
lib/codex-manager/commands/best.ts:295
**command family wiring lacks coverage**

The new model-family handoff is implemented independently in `best`, `forecast`, and `report`, but the added vitest cases exercise only `evaluateForecastAccount`. Direct command assertions that `evaluateForecastAccounts` receives the effective model's `promptFamily` would prevent model parsing or input construction changes from silently regressing this production-critical wiring.

Reviews (1): Last reviewed commit: "fix(forecast): gate availability on the ..." | Re-trigger Greptile

Context used (3)

evaluateForecastAccount checked per-family rate-limit records with a
hardwired "codex" family, so the forecast's --model never reached the
record check and the runtime-overlay staleness cross-check inherited the
same family. A forecast for a general-family model reported an account
ready while its active record had the runtime proxy refusing every request
for that family, and the persisted rate-limited overlay reason backed by
that record was judged stale against the codex family and dropped.

ForecastAccountInput gains an optional family (default codex, so
model-less surfaces keep their exact behavior); forecast, best, and
report resolve it from their model via getModelProfile. The staleness
cross-check becomes family-aware through the same value.

📝 Walkthrough

this is a minor correctness fix. forecast availability now uses the requested model family instead of always using "codex" at lib/forecast.ts. no security or data-loss risk is indicated. regression tests cover matching-family delays and overlays, plus overlays from another family at test/forecast.test.ts.

the main architectural decision is to resolve promptFamily at the command boundary and pass it through ForecastAccountInput at lib/codex-manager/commands/best.ts, lib/codex-manager/commands/forecast.ts, and lib/codex-manager/commands/report.ts. the optional family field preserves compatibility by defaulting to "codex" at lib/forecast.ts.

the tests do not report windows-specific behavior or concurrency coverage. reviewers should verify that family-aware runtime-overlay staleness checks remain correct under concurrent account or overlay updates at lib/forecast.ts.

Walkthrough

forecast commands now pass the selected model family into account evaluation. rate-limit resets and runtime overlays are evaluated against that family. tests cover matching-family delays, matching overlays, and overlays from other families.

Changes

Forecast family propagation

Layer / File(s) Summary
Pass the selected model family
lib/codex-manager/commands/best.ts:3-6, lib/codex-manager/commands/best.ts:295, lib/codex-manager/commands/forecast.ts:17-21, lib/codex-manager/commands/forecast.ts:375, lib/codex-manager/commands/report.ts:477
The best, forecast, and report commands add the selected model’s promptFamily to forecast inputs.

Family-aware rate-limit evaluation

Layer / File(s) Summary
Apply family-specific rate limits

ForecastAccountInput accepts an optional ModelFamily. Reset lookup and runtime overlay validation use that family, with "codex" as the default. Regression tests cover matching and non-matching family records. no windows-specific or concurrency-specific regression cases are shown in test/forecast.test.ts:390-466.

Learning: In ndycode/codex-multi-auth, do not flag explicit imports from "vitest" (e.g., describe, it, expect, beforeEach/afterEach, etc.) in test files as issues—even if the Vitest config sets `globals: true`. The repo’s established convention is to keep these imports for consistency with neighboring tests; removing them would make files outliers.

Timestamp: 2026-06-04T06:14:24.975Z
Learning: In ndycode/codex-multi-auth test files (e.g. `test/*.test.ts`), when creating V3 storage fixtures for accounts, it’s an intentional convention to use `as never` for deliberately minimal stored-account objects that only include `refreshToken`, `addedAt`, and `lastUsed`. Do not treat `as never` here as a type-safety problem: optional/other fields are expected to be populated by the runtime during execution, and the cast is used solely to keep the fixture minimal and consistent across existing tests.
