Stable enum-shaped error key. Branch on this for recovery flows.

Set on 401s to distinguish token failure modes when finer detail is needed. token_revoked_post_claim is the post-#1284 surface for a chrm_app_* that was invalidated by a claim — the recovery field on the same error object carries the self-contained pairing-recovery hint the agent should follow instead of creating a new app.

Present on every plan refusal: the tier the caller was refused under. Its presence is what marks an error as a plan refusal rather than a validation or permission failure.

Which ceiling the call met, keyed by kind. A plan refusal (*_limit_exceeded) names the countable that ran out — version_history, routines_per_app, routines_per_owner, webhooks_per_app, webhooks_per_owner — and pairs it with max. An app_busy refusal names the bound it met and pairs it with observed and allowed; no plan lifts any of them. Two are per-app run bounds, concurrent_runs and runs_per_window; the third, render_token_refresh, is the page render asking for a new render-token secret, held by 10 per app per client IP and 60 per app across every address in a 60 second window, and observed/allowed name whichever of those two refused. An edits_too_large rejection carries the numeric cap that was exceeded instead of a name.

On an app_busy refusal, how hard the app's own refusal ladder is refusing: throttled is the plain ceiling breach above; parked means a caller kept calling inside a wait it was given, so the server mints its own Retry-After (doubling from 60s to a 300s cap) and refuses until a quiet window passes even once the ceiling clears; closed is the same, plus the response closes the connection. Absent on every other kind.

On a *_limit_exceeded refusal, that limit's number on the caller's plan.

On a plan_required refusal, the capability the plan does not include. Never paired with limit / max.

Absolute link to the owner's own billing page, where the refusal is lifted — the team's page for a team-owned app. Omitted only when the owner has no handle and therefore no settings page of their own, so treat it as optional and fall back to your own copy.
