Nine interfaces had exactly one implementation and no test double — they existed
only to be named twice in a DI registration: IFindingsStore, IFindingsStoreLocator,
IPrimeScheduleSignal, IRefineRunner, IWeekReportService, IMergeCoordinator,
IMissionControlPane, IOnlineLoginService, ITaskListFilter. Consumers now depend on
the concrete type; the DTO records that shared those files moved next to their
implementation. IInteractiveLaunchSpecService stays — it carries 54 lines of
contract documentation, which is not ceremony.
IMergeCoordinator in particular had a redundant null object: MergeCoordinator with
a null Handler already no-ops, and every test used the real class with Handler set.
Filtering/ collapses from 8 files to 1. ITaskListFilter and TaskListFilterBase were
a double abstraction over four predicates, with MatchesAsContext => false declared
in both. SmartFlagFilter also compiled its expression twice (its own _flag plus the
inherited Matches cache) — it now uses the cache.
StaticTokenAuthProvider was in src but production uses ZitadelAuthProvider; it is
a test double, so it moves to the test project. Its own test goes away with it.
1. ArgumentList (fix injection): ClaudeArgsBuilder.Build() now returns
IReadOnlyList<string>; ClaudeProcess populates ProcessStartInfo.ArgumentList
instead of Arguments, so values like system prompts are never shell-split.
DailyPrepPrompt, RefinePrompt, and WeekReportService migrated similarly.
All IClaudeProcess fakes updated.
2. ContinueAsync exception guard: wrap RunOnceAsync in try/catch matching
the RunAsync pattern so an unexpected exception never leaves the task
stuck in Running status.
3. Planning chain cascade: OnChildFinishedAsync now calls CancelAsync on
the immediate blocked successor when a child fails or is cancelled,
triggering a recursive cascade that clears the entire remaining chain
instead of leaving it wedged.
4. FailAsync guard: restrict valid source states to Running and Queued;
WaitingForReview -> Failed is now rejected, preventing an invalid
transition that could corrupt the review workflow.
