fix(forecast,runtime): review fixes for #670 and #671 — keep the default forecast on codex, harden the pinned-503 reset by ndycode · Pull Request #672 · ndycode/codex-multi-auth

ndycode · 2026-08-16T11:47:28Z

Summary

Targets fix/forecast-model-family (fix(forecast): gate availability on the requested model's family, not codex #670), not main: the code it fixes only exists on that branch.
fix(forecast): gate availability on the requested model's family, not codex #670 corrected the family axis of forecast availability but left the model axis wrong, so the surface it exists to make truthful still disagrees with the runtime proxy — in both directions.
These are the forecast-side twins of two defects already fixed for the pinned-503 path in fix(runtime): tell the pinned-503 truth — reset time, and no unpin advice for forced pins #671.
Not a review-comment PR: every bot comment on fix(forecast): gate availability on the requested model's family, not codex #670 and fix(runtime): tell the pinned-503 truth — reset time, and no unpin advice for forced pins #671 is already resolved and both are approved and mergeable. This is one defect found by reviewing the diffs themselves.

What Changed

The defect. #670 made the forecast read the requested model's family instead of a hardwired "codex". The record lookup underneath it did not follow:

// lib/runtime/account-status.ts - getRateLimitResetTimeForFamily
if (key !== family && !key.startsWith(`${family}:`)) continue;  // every model in the family
if (minReset === null || value < minReset) minReset = value;     // the EARLIEST of them

Selection does neither. isRateLimitedForFamily (lib/accounts/rate-limits.ts:75) consults exactly two keys — the family-wide key and family:<model> — and the account stays skipped while either is active. Two user-visible consequences:

A sibling model's record reports a delay the proxy would not impose. markRateLimitedWithReason keys token/concurrency limits under family:<model> (lib/accounts.ts:1261). A record on gpt-5.2:gpt-5.6-terra makes forecast --model gpt-5.6-sol read delayed, while the proxy serves that model because neither gpt-5.2 nor gpt-5.2:gpt-5.6-sol is set. The same over-match keeps a stale rate-limited runtime overlay alive through the staleness cross-check, flipping the account to unavailable.
The earliest reset understates the wait. With gpt-5.2 resetting in 5s and gpt-5.2:gpt-5.6-sol in 45s, the forecast advertises 5s; the account is not selectable for 45s.

Both mirror what Greptile already had fixed on the 503 path in #671 — earliest reset misstating recovery and an unrelated model's record inflating it. Forecast never got the same treatment.

The fix.

getRateLimitResetTimeForModel (lib/runtime/account-status.ts) resolves exactly the keys selection consults — via getQuotaKey, so the shape cannot drift from what markRateLimitedWithReason persists — and returns the latest active bound.
ForecastAccountInput gains model; forecast, best, and report pass the normalized id each already resolves, and both injected evaluator contracts name it.
Not a reuse of fix(runtime): tell the pinned-503 truth — reset time, and no unpin advice for forced pins #671's getAccountRecoveryTimeForFamily: that one folds in coolingDownUntil, which forecast already scores separately. Folding it in here would attach a bogus rate limit resets in reason to a cooldown-only account and sustain a rate-limited overlay on cooldown evidence — exactly what the surrounding comment guards against.
Model-less callers are untouched. status and fix pass no model and cannot single out a model key, so they keep the family-wide union through getRateLimitResetTimeForFamily, which also still serves the wait displays. fix(forecast): gate availability on the requested model's family, not codex #670's stated compatibility promise holds verbatim, and there is a test pinning it.

Interaction with #671. git merge-tree pr671 <this branch> is clean — #671 inserts its helper above formatRateLimitEntry, this one appends below it, and both add the same getQuotaKey import. Merge order does not matter.

Validation

npm run lint
npm run typecheck
npm test — 5447 passed. One pre-existing failure in test/zz-stress-helper-lifecycle.test.ts (withDeadPids, test/helpers/owned-pids.ts:182), unrelated to this change: it fails 3 of 4 runs on clean main at 524c397 and on fix/pinned-503-remedy too. A PID-reuse race in the test helper, not a product defect.
npm test -- test/documentation.test.ts — 32 passed
npm run build

New coverage — four behavioral cases, all of which fail on fix/forecast-model-family as it stands:

Test	Without this PR
`test/forecast.test.ts` — sibling model's record ignored	`delayed`, expected `ready`
`test/forecast.test.ts` — later of two gating resets	`5000`, expected `45000`
`test/forecast.test.ts` — overlay dropped when only a sibling backs it	`unavailable`, expected `ready`
`test/codex-manager-report-command.test.ts` — same, end to end through the real evaluator	`delayed`, expected `ready`

Plus a case pinning the model-less union so status/fix cannot regress, and command-level assertions that the normalized id reaches evaluation from best and forecast — extending the family assertions #670 added at CodeRabbit's request.

Suites: test/forecast.test.ts, test/codex-manager-forecast-command.test.ts, test/codex-manager-best-command.test.ts, test/codex-manager-report-command.test.ts.

Docs and Governance Checklist

README updated — not needed; no capability or flag surface changes, only the accuracy of forecast/best/report availability
docs/getting-started.md updated — onboarding unchanged
docs/features.md updated — capability surface unchanged
relevant docs/reference/* pages updated — no commands, settings, or paths changed
docs/upgrade.md updated — no migration behavior
SECURITY.md and CONTRIBUTING.md reviewed for alignment — no impact

Risk and Rollback

Risk level: low. Behavior changes only for callers that pass a model, all of which fix(forecast): gate availability on the requested model's family, not codex #670 introduced and none of which have shipped. Model-less callers (status, fix) take a separate branch and are byte-identical, pinned by test. The new helper is additive; nothing existing changed signature or semantics.
Rollback plan: revert this commit. fix/forecast-model-family returns to its current state with no other branch depending on getRateLimitResetTimeForModel.

Additional Notes

After both this and fix(runtime): tell the pinned-503 truth — reset time, and no unpin advice for forced pins #671 land, getRateLimitResetTimeForModel and getAccountRecoveryTimeForFamily sit side by side with similar key selection. They differ deliberately — the latter folds in cooldown and circuit deadlines for the 503, the former is rate-limit-only for the forecast — but a follow-up could factor out the shared key-set resolution if the duplication starts to drift.
context.model in the proxy is the raw body model, while forecast passes the normalized id. They agree for canonical ids, which is what both the CLI defaults and real codex traffic use; a client sending an alias could still key a record the forecast does not name. Pre-existing on main, out of scope here, noted so it is not lost.

Greptile Summary

this pr adds pinned-account recovery metadata and attempts to align forecast availability with the requested model family.

adds pin-source, reset timestamp, and retry-delay fields to pinned 503 responses
combines exact rate-limit, cooldown, and circuit deadlines for pinned recovery
threads explicit model families through forecast, best, and report, but does not thread the model needed for exact runtime parity
adds vitest coverage for family selection and pinned recovery, but misses sibling-model and overlapping-reset forecast cases

Confidence Score: 4/5

this pr should not merge until explicit-model forecasts use the same exact rate-limit keys and latest gating reset as runtime selection.

forecast, best, and report still aggregate sibling model records and choose the earliest family reset, so their availability and recommendations can disagree with the runtime proxy.

### Issue 1
lib/forecast.ts:252-256
**model-specific forecast gating is broken**

When an explicit model has a sibling model’s rate-limit record or overlapping family and exact-model records, this family-wide helper scans every sibling key and selects the earliest reset, while runtime selection checks only the family and exact model keys until the latest gate expires. This makes `forecast`, `best`, and `report` report incorrect availability or wait times, and `best` can recommend the wrong account.

Knowledge Base — Request Pipeline

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.

…the deps contracts Review follow-up: the injected evaluateForecastAccounts contracts in best and forecast declared their input shape inline without the new family field, so a typed test fake could silently drop it. Both contracts now name family?: ModelFamily. Command-level coverage asserts the resolved family reaches evaluation: best and forecast capture the injected evaluator's inputs (default and explicit --model), and report — which calls the real evaluator — proves it end to end with a gpt-5.2 record that delays a gpt-5.6-sol report and leaves a gpt-5.3-codex report ready.

The pinned-account 503 always advised `codex-multi-auth unpin`, but the pin honored there is state.forcedAccountIndex ?? the persisted switch pin — and for a forced pin (--account / CODEX_MULTI_AUTH_FORCE_ACCOUNT_INDEX) unpin clears nothing, so the advice was wrong exactly where the message appears most: launcher-managed sessions that pin per invocation. The body also carried no recovery time even when the skip reason was a time-bounded record whose reset moment sat in the store. buildPinnedUnavailableErrorBody now takes optional context: pin_source ("forced" pins get a relaunch remedy instead of unpin), and reset_at/retry_after_ms threaded from the blocking record — the family's rate-limit record for a rate-limited skip, coolingDownUntil for a cooldown — with the message naming the reset moment when one is known. The proxy call site distinguishes the pin source it already tracks and resolves the reset for the request's family. Absent context, the body and message are byte-identical to before (the issue-474 expectations pass unchanged).

…skip reason Review follow-ups on both fronts of the recovery metadata: - A direct 429 or network error on the pinned account reaches the 503 with the retry loop's selection verdict (already-attempted) as its skip reason, so gating the reset lookup on rate-limited/cooling-down strings suppressed recovery info exactly where it was freshest. The reset now comes straight from the account's persisted state. - With several overlapping records for the family, the account stays skipped until the LAST one expires, so the earliest reset would send a client straight back into a 503. getAccountRecoveryTimeForFamily returns the latest matching bound (records plus active cooldown), leaving getRateLimitResetTimeForFamily's earliest-reset semantics to its wait-display callers. Covered by test/account-status.test.ts (helper semantics) and two runtime proxy regressions (test/runtime-rotation-proxy.test.ts) that force a pinned account through a direct 429 and a network-error cooldown and assert the 503 carries pin_source, reason, reset_at, and retry_after_ms.

An open circuit breaker outlives the short failure cooldowns that tripped it, so recovery derived only from the persisted account state advertised an early reset — or none at all once the cooldown lapsed — while requests kept 503ing until the breaker's own deadline. The 503 recovery is now the later of the account-state bound and the breaker's next-attempt time, exposed through AccountManager.getCircuitRecoveryTime over the breaker's existing getTimeUntilAvailable. A proxy regression trips the default breaker on a forced pin (with the network-error cooldown zeroed so every request records a failure) and asserts the advertised recovery is the circuit deadline, not the elapsed cooldown.

…uest Selection consults exactly two rate-limit keys per request — the family-wide key and the requested model's key (isRateLimitedForFamily) — so another model's record in the same family never blocks the request and must not inflate its advertised recovery. getAccountRecoveryTimeForFamily now takes the model and considers only those gating keys plus the active cooldown; the proxy passes the request's model through. Unit coverage pins both directions: an unrelated model's later record is ignored, and a model-scoped record alone does not gate a model-less request.

… reuse getQuotaKey Review follow-ups: a disabled, workspace-disabled, auth-invalidated, policy-blocked, or out-of-range pinned account stays unselectable after any concurrent rate-limit record or cooldown expires, so the 503 no longer advertises that record's expiry — selection rejects such an account before any attempt, so the recorded skip reason is reliably the permanent one and gates the suppression. A proxy regression pins a disabled account carrying an active record and asserts reset_at and retry_after_ms stay null. The recovery helper also derives its record keys through getQuotaKey instead of a hand-rolled template, so the shape cannot drift from what markRateLimitedWithReason persists.

… the pinned-503 reset Review fixes on top of #670 and #671. #670 threaded the requested model's prompt family into `forecast`, `best`, and `report`. All three carry a DEFAULT model (`DEFAULT_PROBE_MODEL` / `DEFAULT_LIVE_PROBE_MODEL` = `gpt-5.6-sol`) whose prompt family is `gpt-5.2`, so deriving the family unconditionally silently moved every bare invocation off the codex family: - `codex-multi-auth forecast` / `report` reported an account rate-limited on the codex family as `ready`, and dropped a live `rate-limited` runtime overlay backed by a codex record as "stale" — the exact desync #670 set out to remove, aimed at the default invocation instead. - `codex-multi-auth best` recommended (and `switch` then pinned) an account the runtime proxy refuses for every codex request, since the wrapper's `/codex/responses` path always buckets into the codex family. The family now moves only when the invocation actually carried `--model`; `modelProvided` is tracked in the forecast/report parsers the way `best` already tracked it. Bare invocations keep `evaluateForecastAccount`'s codex default, exactly as #670's description promised. Also from the review: - `report` reuses `modelInspection.promptFamily`, which `inspectRequestedModel` already resolved, instead of calling `getModelProfile` again for every account; `forecast` and `best` hoist the same resolution out of their per-account `.map()`. - `buildPinnedUnavailableErrorBody` no longer feeds an out-of-range epoch to `new Date(...).toISOString()`. The deadline comes from persisted account state (`rateLimitResetTimes`, `coolingDownUntil`), which a corrupted or hand-edited storage file can carry past the ECMAScript time range; the RangeError would have replaced the pinned-503 diagnostics with the proxy's generic 500. - `docs/reference/error-contracts.md` documents the new `pin_source`, `reset_at`, and `retry_after_ms` fields and drops the claim that the pinned 503 only ever comes from a manual `switch` pin. - The circuit-breaker proxy test restores `CODEX_AUTH_NETWORK_ERROR_COOLDOWN_MS` in a `finally` instead of calling `vi.unstubAllEnvs()` mid-test, so an early assertion failure cannot leak the override into later tests.

📝 Walkthrough

this is a major reliability fix, not a security or data-loss change. it corrects model-specific forecast availability and hardens pinned-account 503 recovery. regression coverage exists across forecast selection, command behavior, recovery metadata, timestamp handling, and permanent blockers (test/forecast.test.ts:..., test/runtime-rotation-proxy.test.ts:...).

lib/forecast.ts:... now checks the requested family’s family-wide and model-specific quota keys. it returns the latest active reset and ignores unrelated or expired records.
lib/codex-manager/commands/forecast.ts:..., lib/codex-manager/commands/best.ts:..., and lib/codex-manager/commands/report.ts:... pass model-family data only when --model is explicit. model-less commands retain the codex default.
lib/runtime/account-status.ts:... and lib/accounts.ts:... centralize recovery-time calculation across quota resets and account cooldowns.
lib/runtime-rotation-proxy.ts:... filters unrelated model records, identifies forced versus manual pins, and omits timed recovery for permanent blockers.
lib/request/rate-limit-decision.ts:... adds pin_source, reset_at, retry_after_ms, and skip reasons. invalid and out-of-range timestamps are handled safely.
docs/reference/error-contracts.md:... documents the expanded 503 error contract and recovery guidance.
reviewers should focus on the shared quota-key resolution, family/model filtering, and recovery-deadline precedence. these choices affect runtime account selection and pinned-account fail-hard behavior.
concurrency risks are limited but should be reviewed around persisted quota state and circuit-breaker reads. windows-specific timestamp and line-ending behavior is not explicitly covered. the reported full suite has 5447 passing tests and one unrelated pre-existing stress-helper failure.

Walkthrough

Changes

forecast and pinned recovery behavior

Layer / File(s)	Summary
model-family forecast routing `lib/codex-manager/commands/best.ts:3`, `lib/codex-manager/commands/forecast.ts:17`, `lib/codex-manager/commands/report.ts:49`, `lib/forecast.ts:31`, `test/codex-manager-*:142`, `test/forecast.test.ts:390`	explicit model selections pass their prompt family into forecast evaluation. default probe-model usage preserves codex-family behavior. family-specific rate-limit tests cover commands and runtime overlays.
account recovery-time calculation `lib/accounts.ts:1297`, `lib/runtime/account-status.ts:42`, `test/account-status.test.ts:105`	recovery utilities combine applicable quota resets, cooldowns, and circuit-breaker deadlines. expired and unrelated records return no recovery boundary.
pinned-account error reporting `lib/request/rate-limit-decision.ts:188`, `lib/runtime-rotation-proxy.ts:1591`, `test/rate-limit-decision.test.ts:298`, `test/runtime-rotation-proxy.test.ts:802`, `docs/reference/error-contracts.md:123`	pinned-account 503 responses now report pin origin, reset time, retry delay, and skip reasons. forced pins use relaunch guidance. permanent blockers omit timed recovery metadata.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 63c83

The PR narrows forecast availability and reset calculations to the selected model while preserving model-less behavior. Runtime impact is bounded, and no actionable merge-blocking risk remains; a minor documentation correction for the forced-account environment variable is recommended.

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.

+| `codex_pinned_account_unavailable` | `503` | A pin is in force — either a manual pin (`codex-multi-auth switch`) or a forced per-invocation pin (`--account` / `CODEX_MULTI_AUTH_FORCE_ACCOUNT_INDEX`) — but the pinned account is rate-limited, cooling down, disabled, or blocked by policy. The remedy depends on `pin_source` (see below) |
 | `codex_runtime_rotation_proxy_error` | `500` | Proxy failed before forwarding the request |

 Pool exhaustion includes a `reason`, `retry_after_ms`, and a hint to run `codex-multi-auth rotation status`. Pinned-account-unavailable responses include a `pinnedAccountIndex` field identifying the pinned account, a structured `reason` field carrying the runtime skip reason (for example `rate-limited`, `cooling-down:auth-failure`, `circuit-open`, `disabled`, `workspace-disabled`, `policy-blocked`, `missing`, `already-attempted`) or `null` when no reason was recorded, and an `account_skip_reasons` map keyed by account index that mirrors the pool-exhausted response shape. The human-readable `message` appends the same reason in parentheses when present (see issue #486).

+Pinned-account-unavailable responses also carry:
+
+| Field | Type | Meaning |
+| --- | --- | --- |
+| `pin_source` | `"forced"`, `"manual"`, or `null` | `"forced"` when the pin came from `--account` / `CODEX_MULTI_AUTH_FORCE_ACCOUNT_INDEX`, `"manual"` when it came from `codex-multi-auth switch`. `unpin` clears only a manual pin, so the `message` tells a forced-pin caller to relaunch instead |
+| `reset_at` | ISO-8601 string or `null` | When the blocking state ends — the latest of the gating rate-limit record, the account cooldown, and the circuit-breaker deadline. `null` under a permanent blocker (`disabled`, `workspace-disabled`, `policy-blocked`, `missing`, invalidated auth) or when nothing bounds recovery |
+| `retry_after_ms` | number or `null` | `reset_at` expressed as a delay from the moment the response was built; `null` whenever `reset_at` is `null` |
+
+When `reset_at` is present the `message` appends `; the recorded limit resets at <ISO>`.

use the canonical forced-pin environment variable.

docs/reference/error-contracts.md:123 and docs/reference/error-contracts.md:132 advertise CODEX_MULTI_AUTH_FORCE_ACCOUNT_INDEX, but docs/reference/error-contracts.md:19 and the documented contract use CODEX_MULTI_AUTH_FORCE_ACCOUNT. Use the canonical name, or document both names only if both are supported.

proposed fix

- (`--account` / `CODEX_MULTI_AUTH_FORCE_ACCOUNT_INDEX`) + (`--account` / `CODEX_MULTI_AUTH_FORCE_ACCOUNT`)

As per coding guidelines, “A forced account selected with --account or CODEX_MULTI_AUTH_FORCE_ACCOUNT must be ephemeral.” As per path instructions, keep documentation consistent with actual CLI flags and workflows.

model-specific forecast gating is broken

When an explicit model has a sibling model’s rate-limit record or overlapping family and exact-model records, this family-wide helper scans every sibling key and selects the earliest reset, while runtime selection checks only the family and exact model keys until the latest gate expires. This makes forecast, best, and report report incorrect availability or wait times, and best can recommend the wrong account.

Closing as superseded — everything here landed through #670 and #671 themselves, which are both now merged to main.

This PR merged both branches onto main and fixed them from the outside; instead each fix went onto the branch that introduced the defect, so the contributor's PRs stayed intact and merged on their own.

Where each finding landed:

Finding	Landed in
Default-model family flip in `forecast`/`best`/`report`	#670 `56bf332d`
`modelInspection.promptFamily` reuse + `getModelProfile` hoisting	#670 `56bf332d`
`toISOString` RangeError on the pinned-503 path	#671 `9caadc99`
`docs/reference/error-contracts.md` contract drift	#671 `9caadc99`
Stray author reference in shipped source	#671 `9caadc99`
`vi.unstubAllEnvs()` env-stub leak	#671 `9caadc99`

Two things this PR did not cover also landed:

The model-axis over-gating (lib/forecast.ts:255), which this PR left for the authors — getRateLimitResetTimeForFamily matches every family:* key and returns the earliest, while isRateLimitedForFamily consults exactly family and family:<model> and stays blocked until the later. Fixed in fix(forecast): gate availability on the requested model's family, not codex #670 via getRateLimitResetTimeForModel.
A Greptile P1 raised during re-review: a workspace-disabled 402/403 calls setAccountEnabled(index, false) mid-loop and continues, so selection records already-attempted and the permanent disable was masked — the 503 then advertised the circuit's reset for an account no timer will re-admit. Fixed in fix(runtime): tell the pinned-503 truth — reset time, and no unpin advice for forced pins #671 07b0f91c by re-reading the pin's current runtime state.

The fix/review-670-671 branch is left in place if you want the history.
