Fabro's hooks on a Petri run wrap the hooks the runtime installed for
`[[run.hooks]]` and forward every point. In `prepare_result`, before the
finish is recorded, they commit the stage's files on the run branch of
its host workspace with Fabro's author identity and the run, execution,
firing and attempt as trailers, and publish the commit to a snapshot
repository beside the run's workspaces under a ref per checkpoint. A
stage that failed on its own terms is committed like a successful one; a
commit that fails is fatal: the outcome becomes a `checkpoint_failed`
failure, the run is cancelled through the coordinator handle, and the
transition refuses the firing's routes. In `transition` they write the
platform checkpoint record, keyed on the Petri position and the
checkpoint's operation identity, and a failed write is a recorded
problem.
On restart the server runs the recovery protocol before it relaunches a
worker: a run with a failed checkpoint is reported failed; otherwise
every live execution's last durable finish names the snapshot its
workspace is verified against, reset to, or restored from, with a lost
record reconciled from the snapshot repository, and a finish with no
snapshot fails the run rather than resume it on stale files.
The worker reaches the platform records over two new worker-scoped
endpoints; the server reaches the table directly. A test gate directory
lets the CLI scenarios hold a checkpoint at a named point.

A Petri run executes in the worker process, which resolves the
sandbox-driver plugins itself. The `PETRI_SANDBOX_*` variables (plugin
paths, checksum overrides, dev mode, the Docker host address and the action
host image) now have `EnvVars` names, cross the worker's environment
allowlist with `PATH`, and pass through the test harness's isolation so a
developer's plugin override reaches the servers tests start and the workers
those servers launch.

A workflow version names its engine with `engine = "petri"` in the
`[workflow]` table of `workflow.toml`, and `[server.execution] engine`
(`FABRO_SERVER_ENGINE`, `--engine`) defaults it for every version that
names none. The choice, with what Petri admitted (the lowered root graph
and its children by blob and digest), is recorded on the run spec as
`RunEngine`, carried on `run.created`, and replayed into the projection.
A legacy run's spec omits the field, so existing specs decode unchanged.

Brave stays the default. Shops that already vault VENICE_API_KEY
can drop BRAVE_SEARCH_API_KEY by setting
[server.integrations.search] provider = "venice".

Resolve the model catalog table conflict in docs/public/core-concepts/models.mdx
by keeping both changes: this branch's `kimi` -> `moonshot` provider rename for
the Kimi rows, and main's new DeepSeek V4 rows.

Reduce duplication and over-specification introduced with the Modal
provider, without changing shipped behavior.
- Extract enabled_provider_catalog and assert_deep_tool_round_trip in
the fabro-llm integration tests. The Poolside, Fireworks, OpenRouter,
and Modal deep round trips were four near-identical copies.
- Add ApiCredential::with_extra_headers for providers that authenticate
with request headers instead of an API key.
- Replace the unreachable require_env guards in the Modal e2e test with
the std::env::var form used by every sibling test, and register
MODAL_TOKEN_ID and MODAL_TOKEN_SECRET in EnvVars.
- Collapse modal_requires_both_vault_proxy_tokens to a single case. The
loop rebuilt the whole built-in catalog per iteration.
- Drop tautological and over-specified assertions: the api_key_url doc
URL, the forced default/probe lookups on a single-model provider, and
the get_on_provider loop that could not fail.
- Inline the single-use modal_env_catalog fixture and note why it
overrides the shipped secrets templates.
- Sort the MODAL_* keys in .env.example, and record in modal.toml why
api_id keeps the Hugging Face capitalization.

Adds a disabled-by-default `fireworks` provider to the built-in catalog,
served through the existing openai_compatible adapter/codec. The curated
roster covers Kimi K2.7 Code (default), Kimi K2.6, DeepSeek V4 Pro/Flash,
GLM 5.2, MiniMax M2.7, Qwen 3.7 Plus, and GPT-OSS 120B/20B (small
default + probe), with serverless pricing including cached-input rates.
All api_ids were verified live against /chat/completions (Fireworks'
GET /v1/models only returns a featured subset), and serverless responses
were confirmed to report prompt_tokens_details.cached_tokens, so cache
billing works through the existing codec path.
FIREWORKS_API_KEY is registered as an optional vault secret; provider
login, vault storage, and diagnostics probing are catalog-driven and
need no code changes. Includes catalog/install tests, two live e2e
tests, an integrations docs page, and a provider logo for the web UI.
