When a team-mode subagent hit a fallback model (rate limit / quota
exhaustion on the primary), the fallback continuation started a
fresh subagent session that was not registered in the team's
member registry under the original role. Subsequent
team_send_message / team_status calls from the fallback agent
threw "not in team" because the membership lookup missed.
Capture teamRunId + member identity at fallback initiation and
carry them onto the fallback session so the fallback agent
remains a first-class team participant. If preservation is not
possible, surface a bounded structured error instead of letting
the runtime fail mid-flight with a confusing membership message.

- Fixes BackgroundManager to launch promptAsync before invoking the blocking tmux callback.
- Adds regression test to ensure promptAsync is called before tmux callback.
Treat parsed variant as part of runtime-fallback model equivalence so variant-only fallback hops remain distinct while preserving the existing Claude-family alias handling.
Constraint: Oracle verification flagged unresolved PR #3322 review concerns about variant equivalence and remote state
Rejected: Preserve provider identity in equivalence | contradicted the original live-loop fix for equivalent Claude aliases
Confidence: medium
Scope-risk: narrow
Directive: Any future equivalence broadening must prove both live retry-loop behavior and variant/provider semantics with targeted tests before merging
Tested: bun run typecheck
Tested: bun test src/hooks/runtime-fallback/index.test.ts src/hooks/runtime-fallback/error-classifier.test.ts src/plugin/event.model-fallback.test.ts
Not-tested: Full live end-to-end repro across all provider redundancy policies
Prevent runtime fallback from cycling through provider aliases that resolve to the same underlying Claude family model. This keeps retry handling moving toward a genuinely distinct fallback model instead of appearing to fallback while staying on the same effective model.
Constraint: Live retry/fallback bug is in /Users/ravi/Code/personal/oh-my-opencode, while oh-my-openagent contribution work remains isolated to /Users/ravi/Code/forks/oh-my-openagent
Rejected: Change fallback chain precedence (category vs agent) first | lower-confidence root cause than equivalent-model retry
Confidence: high
Scope-risk: narrow
Directive: Keep alias-equivalence logic limited to model families that are intentionally interchangeable for runtime failover, and expand with targeted tests before broadening provider-family collapsing

Not-tested: Full live end-to-end session repro against external provider outages
Activity signals (tool calls like compress, grep, bash) were treated as
'progress' by the stagnation detector, resetting the stagnation counter
every cycle. This prevented MAX_STAGNATION_COUNT from being reached,
causing infinite continuation loops when models degrade to minimal
responses in long sessions (e.g. GLM-5.1 at ~100K tokens).
Stagnation now only tracks actual todo state changes: incomplete count
decrease, completed count increase, or todo snapshot change. Tool-level
activity no longer resets the stagnation counter.
