Handle OpenCode session events that carry the session ID under properties.info.id or properties.info.sessionID so background tasks and continuation hooks do not miss idle/error/delete events.
Add regression coverage for nested session.idle events completing background tasks and waking continuation hooks.
Reports from david_66 on Discord: sessions get perceived as 'stuck' when
context usage crosses the 78% threshold. Investigation confirmed two
issues in the preemptive compaction hook:
1. PREEMPTIVE_COMPACTION_TIMEOUT_MS was 120s. While the summarize
request is in flight, tool.execute.after short-circuits via the
compactionInProgress guard. A hung summarize blocked the session
for two full minutes before giving up, which users reasonably
experience as a hang.
2. On failure (timeout or exception) only a log line was emitted. The
user had no visibility into why their session was unresponsive or
why auto-compaction never ran, so a transient upstream error could
silently leave them well above the threshold with no signal.
Fix:
- Reduce timeout 120s -> 60s. Still gives the upstream a generous
window, but caps the worst-case perceived hang at one minute.
- Show a warning toast via ctx.client.tui.showToast whenever the
catch block fires, including the underlying error string so users
can act (retry, manual /compact, or adjust provider).
- Include providerID/modelID in the Compaction failed log entry so
wild failures are easier to correlate to a specific target model.
Two existing failure-path assertions were updated to match the new
log shape and a new test covers the toast notification contract.

lastCompactionTime was only set on successful compaction. When compaction
failed (rate limit, timeout, etc.), no cooldown was recorded, causing
immediate retries in an infinite loop.
Fix: set lastCompactionTime before the try block so both success and
failure respect the cooldown window.
- test: add failed-compaction cooldown enforcement test
- test: fix timeout retry test to advance past cooldown
- fix(switcher): use lastIndexOf for multi-slash model IDs (e.g. aws/anthropic/claude-sonnet-4)
- fix(model-resolution): same lastIndexOf fix in doctor parseProviderModel
- fix(call-omo-agent): resolve model from agent config and forward to both
background and sync executors via DelegatedModelConfig
- fix(subagent-resolver): inherit category model/variant when agent uses
category reference without explicit model override
- test: add model override forwarding tests for call-omo-agent
- test: add multi-slash model ID test for switcher
compactedSessions permanently blocked re-compaction after first success,
causing unbounded context growth (e.g. 500k on Kimi K2.5 with 256k limit).
- Clear compactedSessions flag on new message.updated so compaction can
re-trigger when context exceeds threshold again
- Use modelContextLimitsCache for model-specific context limits instead
of always falling back to 200k for non-Anthropic providers
