- The gateway api_server fire webhook acknowledges 202 only after a
durable claim + execution row exist (admission failure stays retryable
as 503; a live claim answers 200 duplicate), then dispatches the
claimed snapshot with the live runner adapters (delivery parity with
the built-in ticker, including relay-fronted and E2EE platforms).
- Legacy single-phase providers (a documented fire_due override without
split hooks) keep being driven through their own hook. Capability
detection now credits claim_fire AND fire_claimed overrides, so
Chronos is correctly classified split-aware (its re-arm lives in
fire_claimed; the redundant fire_due passthrough override is removed).
- Multi-profile dashboards fail closed for external providers: an
unscoped reconcile would disarm other profiles' armed one-shots in the
shared NAS registry.
- Manual runs (cronjob run) carry the owner-bearing claimed snapshot
through every entry point, composing with upstream's manual-run
heartbeat (#76502) and background dispatch.
Note: current main moved the dashboard NAS webhook to a pure
forward-to-gateway design (the gateway owns execution and live
adapters), so the dashboard-side claim/tracking machinery from earlier
revisions of this PR is dropped; the durable admission contract lives in
the gateway webhook path.
