Add support for object-style entries in fallback_models arrays, enabling
per-model configuration of variant, reasoningEffort, temperature, top_p,
maxTokens, and thinking settings.
- Zod schema for FallbackModelObject with full validation
- normalizeFallbackModels() and flattenToFallbackModelStrings() utilities
- Provider-agnostic model resolution pipeline with fallback chain
- Session prompt params state management
- Fallback chain construction with prefix-match lookup
- Integration across delegate-task, background-agent, and plugin layers
Use port 0 fallback when findAvailablePort fails, read the actual bound
port from server.port. Tests refactored to use mock server when real
socket binding is unavailable in CI.

Previously, when an explicit model was configured, the agent name was
omitted to prevent opencode's built-in agent fallback chain from
overriding the user-specified model. This removes that conditional logic
and always passes the agent name alongside the model. Tests are updated
to reflect this behavior change.

Keep BackgroundManager launch and resume from sending both agent and model so OpenCode does not override configured subagent models. Add launch and resume regressions for the live production path.

- #2741: Pass inheritedModel as fallback in subagent-resolver when user hasn't
configured an override, ensuring custom provider models take priority
- #2648: Fix getPlanProgress to treat plans with 0 checkboxes as incomplete
instead of complete (total > 0 && completed === total)
- #2779: Relax Hephaestus single-task guard to accept multi-step sub-tasks
from Atlas delegation, only rejecting genuinely independent tasks
Fixes#2741, fixes#2648, fixes#2779
Tests 'should use default timeout when config not provided' (manager.test.ts)
and 'should use DEFAULT_MESSAGE_STALENESS_TIMEOUT_MS when not configured'
(task-poller.test.ts) failed in CI because Date.now() drifted between
test setup (when creating timestamps like Date.now() - 46*60*1000) and
actual execution inside checkAndInterruptStaleTasks().
On slower CI machines, this drift pushed borderline values across
the threshold, causing tasks that should be stale to remain 'running'.
Fix: Mock Date.now with spyOn to return a fixed time, ensuring
consistent timeout calculations regardless of execution speed.
Tests prove rootDescendantCounts is never decremented on task completion,
cancellation, or error — making maxDescendants a lifetime quota instead of
a concurrent-active cap. All 4 tests fail (RED phase) before the fix.
Refs: code-yeongyu/oh-my-openagent#2700
rootDescendantCounts was incremented on every spawn but never decremented
when tasks reached terminal states (completed, cancelled, error, interrupt,
stale-pruned). This made maxDescendants=50 a session-lifetime quota instead
of its intended semantics as a concurrent-active agent cap.
Fix: add unregisterRootDescendant() in five terminal-state handlers:
- tryCompleteTask(): task completes successfully
- cancelTask(): running task cancelled (wasRunning guard prevents
double-decrement for pending tasks already handled by
rollbackPreStartDescendantReservation)
- session.error handler: task errors
- promptAsync catch (startTask): task interrupted on launch
- promptAsync catch (resume): task interrupted on resume
- onTaskPruned callback: stale task pruned (wasPending guard)
Fixes: code-yeongyu/oh-my-openagent#2700
When the resource URL has a sub-path (e.g. https://mcp.sentry.dev/mcp),
the RFC 8414 path-suffixed well-known URL may not exist. Fall back to
the root well-known URL before giving up.
This matches OpenCode core's behavior and fixes authentication for
servers like Sentry that serve OAuth metadata only at the root path.
Switch background task loop detection from percentage-based sliding window
(80% of 20-call window) to consecutive same-tool counting. Triggers when
same tool signature is called 20+ times in a row; a different tool resets
the counter.
- Replace countedToolPartIDs string[] with Set<string> for O(1) has/add vs O(n) includes/spread (C2)
- Cache resolveCircuitBreakerSettings at manager level to avoid repeated object creation (C3)
- Optimize recordToolCall to avoid full array copy with slice (L1)
Previously, pollRunningTasks() and checkAndInterruptStaleTasks() treated
any non-"idle" session status as "still running", which caused tasks with
terminal statuses like "interrupted" to be skipped indefinitely — both
for completion detection AND stale timeout. This made the parent session
hang forever waiting for an ALL COMPLETE notification that never came.
Extract isActiveSessionStatus() and isTerminalSessionStatus() that
classify session statuses explicitly. Only known active statuses
("busy", "retry", "running") protect tasks from completion/stale checks.
Known terminal statuses ("interrupted") trigger immediate completion.
Unknown statuses fall through to the standard idle/gone path with output
validation as a conservative default.

- Change worktree behavior: default to current directory, worktree only with --worktree flag
- Add mandatory TASK BREAKDOWN section with granular sub-task requirements
- Add WORKTREE COMPLETION section for merging worktree branches back

Display resolved model ID (e.g., gpt-5.3-codex: deep) instead of
agent/category format when modelInfo is available. Falls back to
old format when no model info exists.
Adds a configurable maxToolCalls limit (default: 200) that automatically
cancels background tasks when they exceed the threshold. This prevents
runaway subagent loops from burning unlimited tokens, as reported in #2571
where a Gemini subagent ran 809 consecutive tool calls over 3.5 hours
costing ~$350.
The circuit breaker triggers in the existing tool call tracking path
(message.part.updated/delta events) and cancels the task with a clear
error message explaining what happened. The limit is configurable via
background_task.maxToolCalls in oh-my-opencode.jsonc.
Fixes#2571
Filter out null, undefined, or malformed entries in installed_plugins.json
before accessing properties. Prevents fatal crash on corrupted data.
Addresses cubic-dev-ai review feedback.
