Bug 57d8a047-d26d-47ce-ae6f-bc5cb98fef0e: Opus-tier tasks 404'd because
models/claude-opus-4.yaml pinned default_flags.model to "claude-opus-4-5",
a retired ID. models/claude-sonnet-4.yaml was pinned to a dated snapshot
("claude-sonnet-4-20250514") with the same problem.
Slug strategy: the registry slug (filename / RegistryEntry.name) doubles
as the literal --model argument on the workflow-template pass-through path
(task-templates/workflow/*.yaml `model:` field -> compiler WF-COMP-18 ->
payload.runtime.model -> entrypoint/runners/claude.py `--model`), which has
no translation step through this file's default_flags. So rather than
patch default_flags.model in place (leaving the slug stale and the
pass-through bug latent), rename the slug to match the current API ID:
- models/claude-opus-4.yaml, model-registry/claude-opus-4.yaml
-> claude-opus-5.yaml (name/endpoint/default_flags.model: claude-opus-5)
- models/claude-sonnet-4.yaml, model-registry/claude-sonnet-4.yaml
-> claude-sonnet-5.yaml (claude-sonnet-5)
- model-registry/claude-haiku-4.yaml -> claude-haiku-4-5.yaml
(claude-haiku-4-5); added the previously-missing models/claude-haiku-4-5.yaml
so the claude runner can actually resolve this endpoint
- model-registry/harness-roles.yaml, model-registry/tiers.yaml,
workflows/smart-agent.yaml, task-templates/workflow/{spec,plan}-review-loop@1.yaml:
updated every claude-opus-4 / claude-sonnet-4 / claude-haiku-4 reference
to the new slugs
- models/openrouter-sonnet.yaml: dated snapshot "claude-sonnet-4-20250514"
-> "claude-sonnet-5" (third-party router proxying the same retired ID)
- refreshed cost_per_1k_tokens on the three renamed registry entries to
current published pricing
