## Summary
Graph rendering now accepts documented Fabro dotted DOT attributes end
to end while keeping raw Graphviz calls behind `fabro-graphviz`. The new
`RenderableDot` boundary applies Fabro render styling and normalization
before raw SVG rendering, and both the CLI subprocess and server path
now route through that typed boundary instead of calling `graphviz_sys`
directly outside the graphviz crate.
The branch also adds a small curated DOT compatibility corpus covering
ACP agent attributes, human default choices, and subworkflow manager
attributes. Those fixtures are exercised by both render and validation
tests, and the run overview now shows graph render errors directly
instead of falling through to the empty graph state.

## Summary
This PR makes agent execution a strict two-backend contract: API-backed
stages use Fabro-owned model/provider auth, while ACP-backed stages
launch a user-supplied stdio process that owns its own auth and tools.
That removes the legacy CLI backend and prevents ACP execution from
accidentally resolving or forwarding provider credentials.
## Changes
- Replaces the old `api`/`cli`/`acp` backend model with `AgentBackend {
api, acp }`, with `backend=\"cli\"` rejected and migrated toward
explicit ACP process configuration.
- Splits ACP process configuration into `acp.command` for shell command
strings and `acp.config` for JSON stdio configs, while rejecting legacy
`acp_command`.
- Restricts ACP to `agent` nodes and rejects API-only attributes such as
`model`, `provider`, `reasoning_effort`, `max_tokens`, and `speed` on
ACP nodes.
- Deletes the workflow CLI runtime, CLI credential resolver surface, CLI
live smoke tests, and `agent.cli.*` event handling.
- Updates ACP events and projections to report process identity
(`command`, optional `config_name`) rather than provider/model metadata.
- Updates import/stylesheet propagation, CLI workflow smoke coverage,
server steering tests, and web model extraction for the new
event/backend contract.

## Summary
Moves provider-specific facts out of `AdapterKind` metadata and into
provider catalog data, leaving adapters responsible for runtime protocol
behavior. This makes providers that share an adapter mostly TOML-driven
while still surfacing adapter construction failures during readiness
checks.
## What Changed
- Provider TOML now owns auth mode, API-key/header policy, billing
policy, agent profile, base URLs/env overrides, extra headers, and probe
markers.
- Auth, install, config, diagnostics, and server flows resolve provider
credentials from catalog auth config, including API-key, header-only,
and no-auth providers.
- LLM client registration now reports adapter construction failures,
validates final adapter requests before HTTP dispatch, and preserves
custom primary auth headers.
- Billing and docs now use provider-owned billing policy instead of
adapter metadata, and the old adapter metadata surface is removed.
## Reviewer Notes
OpenAI-compatible `base_url` validation now happens during
adapter/client registration rather than catalog build. That keeps
catalog parsing adapter-agnostic while still letting readiness and model
listing reflect providers that cannot register.
## Verification
- `cargo check -p fabro-model -p fabro-auth -p fabro-llm -p fabro-server
-p fabro-cli`
- `cargo nextest run -p fabro-llm -- adapter_registry`
- `cargo nextest run -p fabro-model -- catalog`
- `cargo nextest run -p fabro-auth -- api_key`
- `cargo nextest run -p fabro-server -- install`

## Summary
Template failures from `fabro run` and structural warnings from `fabro
validate` now preserve source provenance through rendering, workflow
transforms, API serialization, and CLI display. Diagnostics can point at
the actual workflow, import, or prompt file with node/attribute context
instead of surfacing MiniJinja's generic `<string>` source.
## What Changed
- Added named MiniJinja render APIs plus miette-aware `TemplateError`
metadata for source names, source text, spans, and labels.
- Reworked workflow template expansion so inline attributes, imported
workflows, and `@prompt` files render with file and owner context.
- Split strict run behavior from structural validate behavior: run-start
still hard-fails on missing inputs, while validate emits source-aware
warnings and continues linting.
- Extended validation diagnostics through Rust structs, OpenAPI, server
DTO mapping, and CLI rendering with optional source path, line, column,
span, and related metadata.
- Added regression coverage across template rendering, workflow
transforms, CLI output, and the server validate endpoint.

## Summary
This PR advances the catalog-driven LLM work from fabro-sh/fabro#210 by
making the resolved model catalog the source of truth for provider
registration, request control validation, and billing identity. Runs now
preserve canonical provider/model/speed identity through pricing and API
responses instead of collapsing billing around provider API aliases or
model IDs alone.
## What Changed
- Register LLM provider adapters from the resolved catalog, including
custom OpenAI-compatible providers and their credential resolution
paths.
- Validate effective model request controls, including run-level
defaults and node overrides, before dispatching LLM requests.
- Add catalog-aware billing lookup that prices canonical `ModelRef`
values, uses base model costs for standard speed, applies per-speed cost
overrides, and returns an unknown estimate instead of silently billing
zero for unsupported combinations.
- Move Anthropic Opus fast-mode pricing into the built-in catalog for
`claude-opus-4-6` and `claude-opus-4-7`.
- Thread the injected catalog and effective speed controls through
workflow billing, including API-mode and CLI-mode handlers.
- Update billing APIs, server aggregation, generated clients, and the
web billing view to expose provider/model/speed billing identity and
keep standard and fast usage in separate rows.
## Notes for Review
Billing lookup intentionally uses canonical catalog model IDs. Provider
`api_id` substitution remains limited to provider request construction,
so aliases can be used on the wire without changing billing identity.
Event conversion paths that do not have catalog access now preserve
token counts with a null dollar estimate rather than falling back to the
bootstrap catalog.

## Summary
Implemented ACP support as a first-class Fabro backend alongside `api`
and `cli`. This adds a new `fabro-acp` crate using the official ACP Rust
crates, routes `backend=\"acp\"` for agent and prompt nodes, adds
sandbox stdio support for local/Docker/test-support paths, emits ACP
workflow events/projections, updates server steerability handling,
validation, documentation, and black-box CLI coverage.
## Test Plan
Passed strict non-live verification:
- `ulimit -n 4096 && cargo nextest run -p fabro-workflow --run-ignored
all --no-fail-fast` — 1162 passed, 0 skipped.
- `ulimit -n 4096 && cargo nextest run -p fabro-acp -p fabro-sandbox -p
fabro-workflow -p fabro-validate -p fabro-store -p fabro-server -p
fabro-cli --run-ignored all --no-fail-fast -E 'not
test(daytona_streaming_live_smoke)'` — 3125 passed.
- `cargo build --workspace` — passed.
- `ulimit -n 4096 && cargo nextest run --workspace --run-ignored all
--no-fail-fast -E 'not test(daytona_streaming_live_smoke)'` — 5666
passed.
- `cargo +nightly-2026-04-14 fmt --check --all` — passed.
- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D
warnings` — passed.
Live-environment tests skipped/excluded under explicit user override:
- `daytona_streaming_live_smoke` was excluded from final nextest runs
because it requires live Daytona infrastructure and `DAYTONA_API_KEY`.
- Confirmed with `env -u DAYTONA_API_KEY cargo test -p fabro-sandbox
--features daytona --test daytona_streaming_live
daytona_streaming_live::daytona_streaming_live_smoke -- --ignored
--exact --nocapture`: failed fast with `DAYTONA_API_KEY must be set to
run this live smoke test`.
Leftover from when rules.rs was a single 3500-line file. Numbering
was stale (Rule 23 and Rule 24 each appeared twice after the split)
and duplicated info already in the filename.

Remove redundant as_str/from helper methods on provider, reasoning, model-test, safe URL, and interview types. Migrate call sites to Display, IntoStaticStr, and FromStr while keeping wire-format coverage in tests.
No production deployments exist, so there's no need for migration shims.
Remove all six backwards-compat type aliases (AgentError, SdkError,
CoreError, GraphvizError, StoreError, FabroError) and migrate ~880
callsites to use the canonical Error name directly within each crate,
or qualified imports (e.g., `use fabro_llm::Error as LlmError`) for
cross-crate references. Also fix a pre-existing absolute-path clippy
lint in fabro-server error.rs.

Configure clippy `wildcard_imports = "warn"` at the workspace level and
opt all 28 crates in via `[lints] workspace = true`. Fix the three
production glob imports that triggered warnings: fabro-sandbox
read_guard, fabro-cli main, and fabro-api demo module (allowed via
attribute since it constructs many API types by design). Document the
import style convention in CLAUDE.md.

Introduce OOP API for the model catalog: LanguageModel trait with blanket
impl on ModelInfo, Catalog struct with typed methods (get, list,
default_for_provider, closest, build_fallback_chain, etc.), ModelRef enum
replacing ModelId, and Provider::OpenAiCompatible variant. Migrate all
callers across the workspace to use Catalog::builtin() and remove the old
free-function API.

- Add From<ValidationError> for FabroError to eliminate duplicated
.map_err(|e| FabroError::Validation(e.0)) at call sites
- Use top-level `use` imports for stylesheet types in rules.rs
instead of verbose fully-qualified paths
- Remove duplicate parse_condition tests from fabro-workflows
(already covered by fabro-graphviz)
- Use //! inner doc comments in context/keys.rs

Move validation/lint framework and all 24 rules into a dedicated
fabro-validate crate. As prerequisites, move Fidelity, stylesheet
parser/types, and condition parser into fabro-graphviz (where the
Graph types they operate on already live) so fabro-validate can
depend on fabro-graphviz directly without a circular dependency.
