In `@crates/openhuman-core/src/agent/triage/evaluator/chain.rs`:
- Around line 410-416: Update the `OUTAGE_FAILURE_LIMIT` branch in the outage
evaluation flow to retain the entry in `states` instead of removing it. Keep the
failure count, set `in_flight` to false, and schedule `next_attempt_ms` using
`OUTAGE_BACKOFF_CAP_MS` so subsequent triggers remain backed off; preserve
removal on success through `clear_outage`.
- Around line 137-160: Update the retry flow in `run_triage` so an attempt
started by `begin_outage_attempt` cannot leave `in_flight` set if the future is
cancelled or panics. Create an RAII guard for the matching retry key and
generation when an attempt begins; have it clear `in_flight` on drop unless
`clear_outage` or `record_outage` has completed and disarmed it.
- Around line 385-395: Update begin_outage_attempt to gate on in_flight and
next_attempt_ms only when consecutive_failures indicates a recorded outage,
allowing overlapping healthy attempts. Make record_outage and clear_outage
tolerate those overlaps, and ensure a stale-generation failure returns a backoff
Deferred outcome rather than Terminal.
In `@crates/openhuman-core/src/skills/webhooks/bus.rs`:
- Around line 334-336: Update the TriageOutcome::Terminal arm in bus.rs to
return a successful result containing the terminal reason, matching the handling
in ops.rs, so expected terminal outcomes do not flow into error reporting.

Introduce an `OutageAttempt` guard that clears the in-flight flag on drop, preventing stale state when a concurrent attempt finishes first. Change `begin_outage_attempt` to allow retries after consecutive failures even when another attempt is in flight, and replace the removal of outage state at the failure limit with a capped backoff so the system continues to respect the retry schedule.

…n webhooks Add tests to verify that dropping an outage attempt releases the in-flight state and that healthy attempts can overlap while stale failures are deferred. Also change the webhook bus to treat a terminal triage outcome as an Ok result instead of an error, since reaching the terminal state is an expected part of the retry lifecycle rather than a failure.

Extract the outage attempt test module into its own file to reduce the size of the main evaluator chain module, improving maintainability and readability without changing any test behaviour. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Move the test module for outage attempt logic from the parent triage directory into the evaluator submodule, updating the module path accordingly. This keeps test code co-located with the implementation it exercises and removes the stale test file and its corresponding baseline entry. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The merged dependency graph now resolves three fewer unique crate names in the flows profile, matching the lowered kernel floor recorded in the limits file. The calibration script and the kernel-floor limits are updated accordingly, and a legacy browser assembly file is pinned to prevent its size from growing with this change.

The gated test allowlist in the CI script was updated to remove entries for test files that no longer exist, and the ignored test baseline count was adjusted from 31 to 26 to reflect the removal of these entries. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

… failures When a managed backend recovers during a concurrent outage attempt, the record_outage function now returns a deferred outcome instead of panicking when the outage state has been cleared. The begin_outage_attempt function also correctly prevents multiple initial attempts from being in flight simultaneously by checking the in_flight flag before the retry timing condition. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The condition guarding the early return in `begin_outage_attempt` was split across three lines, making it harder to read than necessary. The change collapses it onto a single line, preserving the exact same logic while improving local readability. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Summary
Problem
Managed backend 5xx responses could cause background triage to repeat the same cloud attempt at a fixed 30-second interval. The background callers logged and dropped the defer timestamp, and configurations without a local arm had no executable fallback.
Solution
The shared triage evaluator now owns provider/model outage admission, in-flight generation tracking, capped backoff, and terminal exhaustion. Successful cloud or local fallback outcomes clear the matching outage generation. Deterministic tests cover cross-invocation suppression, the backoff schedule and cap, terminal exhaustion, model isolation, and existing fallback behavior.
