fabro-types no longer re-exports the lithos catalog and request types
(ProviderId, ModelId, ModelHandle, Message, ContentPart, TokenCounts,
Cost, Speed, ReasoningEffort, ReasoningOutput, and the rest). Every
crate that uses them depends on lithos-llm and names them there, and
the fabro-api progenitor replacements point at the lithos paths.

lithos-llm now ships the built-in provider ids and constructors, so
fabro-types drops its provider_ids module and every caller uses
lithos_llm::catalog::builtin directly. The crates that name a provider
now depend on lithos-llm themselves.

The reasoning-effort substitution rule now lives on lithos's
ModelCapabilities, so the workflow fallback planner calls it directly
and fabro-types drops its controls module. ReasoningEffort is re-exported
from lithos alongside the other request types.

Delete fabro-llm's attachments, reasoning, and structured modules and
the LlmError newtype and ErrorFacts trait. lithos-llm now provides all
of them: InlineLocalFiles under the local-files feature, ReasoningOutput
with Response::reasoning(), Client::complete_object, and the retry,
auth, cancel, and failover predicates directly on Error and ErrorData.
fabro-llm keeps only failure_signature_hint, which is Fabro's own loop
detection policy.
Store ErrorData directly in the agent and workflow error enums, boxed
where the variant would otherwise dominate the enum size. Repin
lithos-llm to a1e3fd3 for these additions.

fabro-llm's catalog module held some 250 lines of listing and picking
helpers over lithos data: enabled and listed providers, model lookup by
id, alias, or wire id, matches ranked as the resolver ranks, default and
probe models, the small utility model across ready providers, the nearest
model on another provider, and cost by handle. lithos-llm now answers all
of those on `Catalog` and `CatalogProvider` through `Offering`, so the
helpers and the `ModelEntry` wrapper go.
What stays in Fabro's catalog module is its own: building the catalog from
the operator overlay, and reading the agent harness and
`reasoning_by_default` from the shared `metadata.agent` namespace. The
passthrough selection policy in `selection.rs` keeps its rules and calls
lithos for the lookups.

fabro-auth defined its own `CredentialSource` trait beside the lithos
`CredentialProvider`, with a parallel `ResolveError` and an adapter between
them, because lithos had no way to ask which providers a store can serve
right now. It does now: `credentials::readiness`, `ClientBuilder::build_ready`,
and `CredentialError::Unusable`.
- The vault, SQL vault, API-key, and extra-headers stores implement
`CredentialProvider` directly. Material that is present but unusable (an
expired token with no refresh, a wrong-typed vault entry, a header secret
that did not resolve, a store read failure) is `CredentialError::Unusable`
with the operator-facing reason; its `Display` replaces
`auth_issue_message`. `is_configured` is the cheap presence check.
- `fabro_llm::build_client` calls `build_ready`; `FabroClient::auth_issues`
carries `CredentialError`. `fabro_llm::configured_providers` replaces the
per-store `configured_providers` method.
- `CredentialSource`, `ResolvedCredentials`, `lithos_credentials`,
`ResolveError`, and `auth_issue_message` are deleted. Twenty files that
held `Arc<dyn CredentialSource>` hold `Arc<dyn CredentialProvider>`.

lithos-llm now exposes `ReasoningEffort::ALL`, `Speed::ALL`, `as_str`,
`Display`, and `FromStr` on its request-control enums. Fabro's
`controls` module kept parallel name tables and parsers for them; only
the nearest-supported-effort rule is Fabro's own, so that is what stays.

Fabro's policy layer restated the lithos built-ins under `metadata.fabro`:
enabled flags, credentials, display facts, probe and small-default roles,
and agent profiles. lithos-llm now carries every one of those as a core
field or under the shared `metadata.agent` namespace, so the layer and its
typed view go:
- Delete `fabro-policy.toml` and `FABRO_POLICY_TOML`. The catalog is the
lithos built-ins plus the operator's `[llm]` overlay, nothing between.
- Delete `fabro_types::catalog_policy`. `enabled`, `stands_in_for`,
`api_key_url`, `family`, the cutoffs, `estimated_output_tps`,
`small_default`, and `probe` are read from lithos accessors; the agent
profile and `reasoning_by_default` come from `metadata.agent`, which
Pebble reads too.
- `catalog::provider`, `enabled_providers`, and `listed_providers` return
the lithos `CatalogProvider` directly; `ModelEntry` loses its policy
field and gains `agent_profile()`.
- Test fixtures move `[providers.x.metadata.fabro] enabled = true` onto
the provider table, drop `credentials` lists in favor of the secret name
lithos derives from the provider id, and spell `agent_profile` as
`metadata.agent.profile`.

lithos-llm now owns which named secrets each provider reads and how they
shape into its auth scheme, including a derived `<PROVIDER>_API_KEY` for
operator-defined providers. Fabro's job shrinks to supplying the store:
`VaultCredentialSource` hands lithos a lookup that reads the process
environment, then the vault, under the same conventional names.
What Fabro still adds on top: the Codex OAuth credential in the vault,
refreshed and persisted when it expires; `{{ secrets.NAME }}` tokens in a
provider's `default_headers`, resolved against the vault and re-sent as
credential headers; and OpenAI organization and project headers from the
environment.
Deleted with the `metadata.fabro.credentials` list: `CredentialRef`,
`CredentialResolver`, `EnvCredentialSource` (now
`VaultCredentialSource::environment_only`), and the `env_var_names` /
`expected_vault_secret_name` helpers, replaced by `secret_names` and
`expected_secret_name` over the lithos table. `openai-codex` joins the
first-party provider id constants.

Workflow LLM handlers build lithos requests, bill from lithos usage and
cost, and classify failures from lithos `ErrorKind`. Model resolution and
fallback use the fabro-llm selection and catalog helpers. Validation
rules read the lithos catalog, and store fixtures use the new
`BilledModelUsage` shape.

Share canonicalize_location and resolve_existing_workflow_location
between the local package resolver and the version collector, drop the
redundant package-root pre-check and the PackageFileReadError enum in
favor of anyhow context, and read HEAD's SHA from git2 instead of a
separate rev-parse subprocess.
Make GitRunTargetObservation a plain struct, replace the repo-info
tuple with a named struct, tighten the closure view trait, avoid
deep-cloning the root workflow during collected validation, remove the
unused into_closure accessor, and dedupe test helpers.

`DaytonaSnapshotSettings` carried two independent `Option`s (`image` and
`dockerfile`) that every consumer had to re-validate. Replace them with a
single `source: DaytonaSnapshotSource { Image, Dockerfile }` so the
both-set and neither-set states are unrepresentable at the sandbox layer.
This removes four unreachable error arms in `canonical_manifest` and
`create_snapshot_params`, the `.filter(...)` guard in `initialize`, and
the presence guard in `daytona_config_from_environment`. The
mutual-exclusion rule now lives only in fabro-config, which owns the
`image.docker` / `image.dockerfile` keys the old messages named.
Merge `ImageSnapshotManifest` into `SnapshotManifest` via a flattened
`SourceManifest` enum. The dockerfile case serializes to the same bytes
as before, so existing snapshot names are unchanged; the pinned identity
test still passes. Pin the image-case identity as well so a future
manifest change cannot silently orphan image snapshots.
Fold `validate_daytona_image_settings` into the existing Daytona arm of
`validate_provider_capabilities`; both callers already invoke it right
after `resolve_environment_fields`, so error order is unchanged.

Introduce a PinnedRevision enum in clone_source so the Docker and Daytona
providers run one fetch/checkout/verify sequence for both an exact commit
and a tag instead of two near-identical arms. Fold the tag-specific
command builders into the generic ones, share the bare-ref grammar check
between branch and tag validation, and derive the workflow clone source
from the validated Git target in a single match.

A failed node with an effective `succeed` policy and no explicit recovery
route now finishes as `succeeded` and follows normal success routing. The
original failure stays on the outcome so the stage.completed event and the
checkpoint keep the diagnostic, and the outcome notes record which scope
promoted it.
- OnFailure gains a Succeed variant; Node::on_failure resolves the
deprecated auto_status=true attribute as an alias, with an explicit
on_failure winning
- The core executor applies the policy before the lifecycle observes the
result, so the recorded outcome, context keys, goal gates, events, and
routing all see the effective outcome; this replaces AutoStatusLifecycle
- Explicit routes take priority: a matching condition, preferred label,
suggested next node, or handler jump keeps the outcome failed. A failed
outcome takes an unconditional edge only under route, so under succeed
any edge selection is an explicit route
- succeed applies only to failed, matching exit; the auto_status alias no
longer promotes partially_succeeded
- Parallel branches promote after their retry loop, so a failed succeed
branch counts as succeeded in the parent aggregate
- Validation accepts succeed and adds an auto_status_deprecated warning
that suggests on_failure="succeed"
- Document the policy table, semantics, and deprecation; add a changelog
entry
Closes#807

A node can now set its own on_failure attribute to override the
graph-level failed-node routing policy in either direction: a
best-effort node can keep route inside an exit graph, and a critical
node can exit while the rest of the graph keeps the default. An absent
node attribute inherits the graph policy.
- Node::on_failure returns Option<OnFailure> so absence means inherit
- Graph::resolve_on_failure(node_id) is the single resolution point,
returning ResolvedOnFailure { policy, scope } so the executor's
end-of-run message names the scope that stopped routing
- The core Graph trait method becomes resolve_on_failure(node_id); the
graph-scope failure message is unchanged
- The failed-human-gate fallthrough block stays independent of a
node-level route override
- Validation now accepts and value-checks node-level on_failure (it
previously warned that node placement had no effect) and keeps the
edge-placement warning with updated wording
- Document precedence in transitions, failures, and the DOT reference,
and extend today's changelog entry

Apply cleanup review findings on the model stylesheet template branch:
- Move the root-only stylesheet rule into visit_graph_references via a
GraphPosition parameter, so the bundler and workflow-version stop
re-implementing the entrypoint guard with duplicated match arms
- Let ModelStylesheetTemplateTransform build its own template store and
skip the pass entirely when the graph has no stylesheet; drop its dead
Transform impl and the template_render_store re-export
- Parse fix-message namespaces with the typed Namespace enum, share the
vars/goal fix strings with script_interpolation_fix, and replace the
attribute_name magic-string check with a restricted-namespace fix the
stylesheet transform sets on its own render target
- Drop template_render_store's content parameter; the store's render
always overwrites it before rendering
- Trim redundant tests and add a transform_options() helper in
pipeline/validate.rs tests

Collapse the triple Folder dispatch in run-intent admission into a single
prepare_intent_target call that canonicalizes and observes Git under one
provider gate, and stop feeding target/git into the compiler input only to
overwrite them afterwards. In run start, hoist the duplicated Folder
rejection out of the Docker and Daytona arms, restore kind_name() for the
Git/None arm, and drop the unreachable absolute/symlink checks that follow
canonicalize. Dedupe the folder-target test fixtures in both crates.

Use /tmp/fabro/runtime for both Docker and Daytona instead of
provider-specific roots. A writable /tmp inside the sandbox is already
a dependency (commit-message files, exec stop-files), it needs no
root-level mkdir for non-root container users, and it makes the two
providers uniform.
The trailing runtime path component stays load-bearing: materialized
blobs at runtime/blobs/{hash}.json are recognized as managed blob
references and normalized back to blob:// in durable context.

Remote prompt-value materialization wrote demoted values to
{working_directory}/.fabro/blobs inside the repository checkout, so a
later checkpoint could commit them and leak them into the run pull
request.
Give each sandbox a run-scoped runtime directory outside the source
checkout as part of the Sandbox contract:
- Sandbox::runtime_directory() names the directory; host-local
sandboxes return None because the engine owns a host-side runtime
directory (RunScratch) for those runs.
- Docker creates /fabro/runtime at initialize with umask 077 and
uploads runtime files with mode 0600.
- Daytona creates /home/daytona/fabro/runtime with mode 0700.
- Both remote materialization paths in fabro-workflow share one
materialization-path helper built on the new contract. The paths keep
the runtime/blobs suffix, so durable context still normalizes to
blob://sha256/... references.
- Local materialization now writes owner-private directories and files
on Unix.
Regression coverage: an integration test runs remote-style prompt
demotion against a real git checkout, then a real checkpoint commit,
and asserts the checkout stays clean, the agent-facing file is
readable, and a deleted materialized file is recreated from the
durable blob store. A real-Docker test verifies the runtime directory
and blob file permissions inside a container.

test_blob_store was a process-wide OnceLock singleton over one in-memory
SQLite connection, so content-addressed rows written by one test were
visible to every other test in the same process. nextest's
process-per-test model masked the bleed, but plain cargo test failed
(8/24 in fabro-workflow-version) because negative existence assertions
became order-dependent.
test_blob_store now builds a fresh isolated in-memory store per call,
and test_database gives every database its own blob authority.
Reopen-style tests that model one durable blob authority across several
store handles use the new test_blob_store_at, which keeps the blob table
in a SQLite file beside the store directory, plus
test_database_with_blobs to share it explicitly.

fabro-workflow's and fabro-server's src/test_support.rs import
fabro_store::test_support, but their test-support features never enabled
fabro-store/test-support. Workspace builds passed only through feature
unification from other members' dev-dependencies, while per-crate builds
such as `cargo check -p fabro-cli --tests` or
`cargo check -p fabro-server --features test-support` failed with E0432.

Blob activation cleanups:
- Reuse fabro-db's append_to_path, remove_file_if_exists, and
set_private_permissions instead of local duplicates.
- Return the store directly from activate_blob_storage; the report
wrapper existed only to be logged internally and then discarded.
- Collapse compute_disk_preflight to return the required free bytes
instead of echoing its inputs back through a struct.
- Deduplicate the "exactly one ok row" PRAGMA integrity_check protocol
into one executor-generic helper used by the backup and live checks.
- Skip re-validating a freshly published backup; the staging copy was
validated immediately before the atomic rename, so only a
concurrently published file needs its own validation.
- Replace the manual anyhow wrapping plus duplicate error log in
serve.rs with a plain .context(), matching other startup errors.
- Extract the disk-candidate enumeration in resource_sampler.rs that
available_space_for_path had copy-pasted from sample_disk_resources.
Test fixture cleanups:
- Route all hand-assembled Database::new(..., test_blob_store()) test
fixtures (32 sites) through fabro_store::test_support::test_database,
and make that helper infallible instead of returning an unconditional
Ok.
- Install the test blob schema from fabro_db::BLOBS_MIGRATION_SQL via a
test-support-gated optional dependency instead of a four-level
relative include_str! into fabro-db's migrations directory.
