Problem

When the host is temporarily resource constrained, a foreground health probe can time out even though the existing session is still valid. Immediately replacing that session can start a reconnect while the same host is still stalled, leaving the client unusable until it recovers.

Fix

Keep the existing desktop/web session after the first foreground probe timeout. A successful probe resets the count, while a second consecutive timeout still triggers normal recovery. Definite probe failures and mobile resume behavior are unchanged.

Testing

  • Focused connection supervisor suite: 35 tests passed
  • Client-runtime typecheck
  • Targeted lint and formatting checks

Model: GPT-5; harness: Codex.


Note

Medium Risk
Changes live connection monitoring and reconnect timing in client-runtime; behavior is well-covered by supervisor tests but affects when sessions are replaced under load.

Overview
Foreground health probes on application-active no longer tear down the session on a single 15s timeout when the host is briefly stalled. The supervisor keeps the existing lease, logs a warning, and only triggers normal reconnect recovery after two consecutive timeouts (FOREGROUND_PROBE_TIMEOUTS_BEFORE_RECONNECT).

A successful probe resets the counter. Definite probe failures and application-active-probe (mobile, 3s timeout) behavior are unchanged.

Tests cover: one timeout stays connected; two timeouts → backoff/release; success between timeouts resets the count.

Note

Tolerate transient foreground liveness probe timeouts in EnvironmentSupervisor

  • During application-active wakeups, a single probe timeout no longer triggers a reconnect; the supervisor only reconnects after 2 consecutive timeouts (FOREGROUND_PROBE_TIMEOUTS_BEFORE_RECONNECT = 2).
  • A successful probe resets the timeout counter to 0, so isolated timeouts are always tolerated.
  • application-active-probe signals retain the existing fail-fast behavior on timeout.
  • Two new tests cover consecutive timeout reconnection and counter reset after a successful probe.

Approvability

Verdict: Needs human review

This PR changes runtime behavior for connection supervision - tolerating transient foreground probe timeouts before reconnecting instead of failing immediately. This modifies core connection handling logic and should be reviewed by someone familiar with the supervisor implementation.

Problem

When the host is temporarily resource constrained, a foreground health probe can time out even though the existing session is still valid. Immediately replacing that session can start a reconnect while the same host is still stalled, leaving the client unusable until it recovers.

Fix

Keep the existing desktop/web session after the first foreground probe timeout. A successful probe resets the count, while a second consecutive timeout still triggers normal recovery. Definite probe failures and mobile resume behavior are unchanged.

Testing

  • Focused connection supervisor suite: 35 tests passed
  • Client-runtime typecheck
  • Targeted lint and formatting checks

Model: GPT-5; harness: Codex.


Note

Medium Risk
Changes live connection monitoring and reconnect timing in client-runtime; behavior is well-covered by supervisor tests but affects when sessions are replaced under load.

Overview
Foreground health probes on application-active no longer tear down the session on a single 15s timeout when the host is briefly stalled. The supervisor keeps the existing lease, logs a warning, and only triggers normal reconnect recovery after two consecutive timeouts (FOREGROUND_PROBE_TIMEOUTS_BEFORE_RECONNECT).

A successful probe resets the counter. Definite probe failures and application-active-probe (mobile, 3s timeout) behavior are unchanged.

Tests cover: one timeout stays connected; two timeouts → backoff/release; success between timeouts resets the count.

Note

Tolerate transient foreground liveness probe timeouts in EnvironmentSupervisor

  • During application-active wakeups, a single probe timeout no longer triggers a reconnect; the supervisor only reconnects after 2 consecutive timeouts (FOREGROUND_PROBE_TIMEOUTS_BEFORE_RECONNECT = 2).
  • A successful probe resets the timeout counter to 0, so isolated timeouts are always tolerated.
  • application-active-probe signals retain the existing fail-fast behavior on timeout.
  • Two new tests cover consecutive timeout reconnection and counter reset after a successful probe.

Approvability

Verdict: Needs human review

This PR changes runtime behavior for connection supervision - tolerating transient foreground probe timeouts before reconnecting instead of failing immediately. This modifies core connection handling logic and should be reviewed by someone familiar with the supervisor implementation.

Closing in favor of #8522, which carries the same foreground-probe timeout fix on the current connection supervisor and preserves its updated reconnect behavior. Keeping the review in one place.
