Description

assertion `left == right` failed
  left: Premium
 right: Standard

## Description

`tests/integration_agency_pipeline.rs::assigner_to_creator_signal_path_exists` (line 670) fails on current `main`:

```
assertion `left == right` failed
  left: Premium
 right: Standard
```

The test asserts `DispatchRole::Creator.default_tier() == Tier::Standard`, but `src/config.rs:1115` returns `Tier::Premium` for Creator. The `default_tier()` doc comment at `src/config.rs:1100-1101` says "creator and verification get standard (sonnet)" — so the comment matches the test, but the code matches neither.

This was introduced/exposed by `agent-4/cheap-by-default` (commit `72cfe692e`). Decide which is correct (Standard or Premium for Creator) and align the other two.

## File scope
- `src/config.rs` (around line 1100-1119)
- `tests/integration_agency_pipeline.rs` (line 670)

## Validation
- [ ] `cargo test --test integration_agency_pipeline assigner_to_creator_signal_path_exists` passes
- [ ] doc comment on `default_tier()` matches the impl
- [ ] cargo build + cargo test pass with no regressions

• 2026-04-26T22:45:17.415638337+00:00 Decision: align doc comment + test with current code (post-78bb9e2ce intent: TaskAgent=Standard, Creator=Premium, Verification=Premium). The 78bb9e2ce/make-tiers commit was the more recent intentional change; the test and doc comment were missed in that update.
• 2026-04-26T23:00:07.920463968+00:00 Validated: cargo test --test integration_agency_pipeline assigner_to_creator_signal_path_exists passes; full integration_agency_pipeline.rs (37 tests) passes; cargo test --lib (1943 tests) passes. Two unrelated flakes observed (debounces_burst_writes, provenance_full_lifecycle_all_ops_recorded) — confirmed pre-existing on main, not caused by this change.
