docs: stop promising a 429 failover kill switch that no longer exists - #3520
Conversation
The configuration and CLI references said oauthAccountFailover.enabled: false turns rotation off, and that anthropicAccountPool.enabled gates 429 failover. Both were true when written and both stopped being true when reactive and proactive activation were split. Public docs that contradict the runtime are worse than missing docs: an operator reads them, concludes a rate limit is terminal, and enables an experimental pool to buy recovery they already have. Corrected across en plus seven translated locales, with a test pinning the claim so a nine-locale set cannot drift back one file at a time.

The runtime/documentation correction is valuable, but the new regression is not yet a reliable oracle. All three Bun.file(...) reads are cwd-relative, contrary to the current AGENTS.md source-oracle rule; resolve each through tests/helpers/repo-root.ts so running the test from another directory cannot fail or read the wrong tree. More importantly, the translated-locale assertion only requires 429 and any bold span. A translation can regress to claiming that the switch enables/disables 429 failover, add bold formatting, and still pass. Pin one locale-specific corrected/negative marker per locale (or another machine-checkable semantic marker) that actually distinguishes “429 is not controlled here / cannot be disabled” from the old promise. Please keep the exact-head CI requirement after that test update.

Register docs-429-failover-claims.test.ts in both scripts/test-layout/layout.json under explicit and tests/fixtures/test-layout-expected.json. The broad docs- regex happens to classify it today, but leaving a newly added test out of the authoritative maps makes the migration inventory incomplete and allows later resolver changes to silently reclassify it.

These repository-relative strings are resolved against the process working directory, so running the focused test from tests/ fails all three cases with ENOENT; use repoPath(...) from tests/helpers/repo-root.ts for every documentation read instead. This also keeps the source-oracle test independent of its eventual layout migration.

With anthropicAccountPool omitted or disabled and two eligible accounts stored, rotateAnthropicAccountOn429 still records the cooldown and rotates because src/oauth/anthropic-routing.ts:641-647 gates recovery on the account quorum. However, the paragraph immediately below this newly corrected row still says “When enabled, 429 records…” (and the translated pages retain equivalent wording), so the page now gives operators contradictory answers about whether disabling the pool disables recovery; update that paragraph and its translations to describe the presence-driven behavior too.

Limit the threshold-0 wording to proactive switching.
The canonical English documentation states that autoSwitchThreshold: 0 disables proactive usage-based switching only. New-session selection and recovery after an eligible 429 still use quotaWindow. These translated rows instead say that threshold 0 disables quota selection.

Remove the stale enabled gate from all translated Anthropic configuration pages.
The new table rows correctly state that anthropicAccountPool.enabled does not control 429 recovery, but each page still conditions the following 429 paragraph on the feature being enabled. Rewrite each paragraph to describe account-driven recovery independently of this setting.

Summary
The published docs still promise a 429-failover kill switch that no longer exists.
Two claims went stale when #3495 split reactive from proactive activation, and both survived in the reference pages across eight locales:
oauthAccountFailover.enabled: falsewas documented as turning rotation off. It now declines only the pre-dispatch account preference — it cannot stop 429 recovery.anthropicAccountPool.enabledwas documented as "Enable sticky affinity and 429 cooldown failover". The 429 half is no longer gated there at all.Both were true when written. Neither is now.
Docs that contradict the runtime are worse than missing docs here, because of which way they are wrong: an operator reads that a rate limit is terminal without the pool, and switches on an experimental feature — one whose own warning says Anthropic may restrict accounts that look like automated rotation — to buy recovery they already have unconditionally.
Corrected in the English source and the seven translated locales that repeat the claim, each phrased natively rather than machine-substituted. The generic knob is described by what it still refuses instead of being deleted, since it does retain a real meaning.
Verification
bun run typecheck— clean.bun testacross three focused files — 35 pass, 0 fail.The new test pins the corrected claim in the source locale and asserts the translated locales carry the same shape. That last assertion is the point: a nine-locale set drifts one file at a time, which is exactly how the original inconsistency survived a full review.
