Adds HandlerTriageAlias/HandlerWaitAlias/HandlerMergeAlias to ModelRegistry and
replaces PromptKind.MergeHelperExecute with MergeHelperWait (phase 3 only) and
MergeHelperMerge (phases 4-5), so the list handler can run as three
cost-scoped sessions instead of two. Triage's Phase 2 now checks/sets a wide
verify command via get_list_config/set_list_config once per run. Merge now
merges before reruns, delegates diff review to a sonnet subagent, rejects
0-file diffs, tracks the merged-but-not-Done verify-gate outcome, and caps
reruns at one per task via handoff_list_handler's new nextPhase parameter.
InteractiveLaunchSpecService.cs still references the removed
PromptKind.MergeHelperExecute and fails to build -- wiring the Worker/UI side
onto the new roles is a follow-up task.
A full model id like claude-sonnet-4-6 in list_config.model never matched any
ModelPresets row (only bare aliases did), so every run under it landed on the
hardcoded 30-turn/DefaultLevel fallback instead of the sonnet preset row -
this is what killed two autonomous tasks at the 30-turn limit.
ModelRegistry.TryNormalizeAlias (non-throwing: exact match, then substring
match against a full model id) lets ModelPresets.For resolve a full model id
to its alias's preset row. For a model that still doesn't resolve, the
hardcoded 30 is replaced by a caller-supplied fallbackMaxTurns, and TaskRunner
now passes AppSettings.DefaultMaxTurns there - so that setting has a real
effect instead of being dead, matching the direction already noted in
docs/open.md.
AddTask, planning CreateChildTask, and SuggestImprovement now accept an
optional alias-validated model (haiku/sonnet/opus; blank = inherit) so the
model is chosen at creation time instead of a follow-up set_task_config call.
The planning, system, and improvement prompts instruct Claude to pick the
cheapest capable model (haiku < sonnet < opus).
