Standalone provider

This provider no longer exists in KiroCrew. The public fork drives a single backend — kiro-cli over the Agent Client Protocol (agent.provider is fixed to acp). The removed standalone provider, the removed Bedrock provider, the removed agent-renderer / mirror modules, their config fields, and the dashboard provider selector were all removed during de-Amazoning. There is no provider to choose.

What remains (the dormant ACP seam)

acp/client.py keeps an inert protocol seam (ACP_BACKEND_CLAUDE / the _is_claude branch) so an internal companion package can re-register an alternate claude-agent-acp backend without forking the client. The public core never selects it: _resolve_kiro_bin is the only backend the provider factory wires, and the dashboard exposes no provider choice. Do not re-add the registration glue or a provider selector — see the repo-root CLAUDE.md.

The seam's binary-resolution details (_resolve_claude_acp_bin, the per-session settings.local.json permission routing, CLAUDE_CONFIG_DIR isolation) are documented in acp-client.md for the companion that re-enables it — they are not user-facing in the public build.

Model registry

model_registry.json (loaded by model_registry.py, mirrored to website/src/model_registry.json and guarded by test/test_model_registry_parity.py) remains the single source of truth for model names and context windows. Its per-entry providers map keys models under the canonical claude_code namespace — that is just the canonical key form (the public ACP model-id shape, e.g. global.anthropic.claude-opus-4-8[1m]); it is not a selectable provider.

Canonical keys include fable-5-1m (leads the JSON but is not default — Opus 4.8 opus-4.8-1m remains the sole "default": true entry), and available_models() (model_registry.py) is default-first-ordered, so a non-default entry sitting ahead of Opus in the file cannot change the auto-path pick. Each entry's aliases also include the bare, prefix-stripped provider-id spelling (e.g. claude-fable-5) so from_provider_id folds bare ids onto the canonical key.
