The openai_compatible stream decoder grew its tool call accumulator with
empty placeholder entries whenever a delta arrived with a sparse index,
then emitted every slot as a real tool call at finish. A provider that
numbers tool_calls[].index wrongly (Venice's Anthropic translation
passes through content-block positions, so a first tool call after text
arrives with index 1) therefore produced a phantom tool call with an
empty id and name. The phantom poisoned the conversation: the agent
answered it with a tool error, and the next request was rejected by the
provider (400: tool_use.id must match '^[a-zA-Z0-9_-]+$'), failing the
run as a non-retryable deterministic error.
A gap in the index sequence is indistinguishable from lost chunks, so
the decoder now fails the stream with a clear error naming the provider
and index instead of fabricating a tool call. Error::Stream is
classified retryable, so stage retries resample the turn rather than
replaying a poisoned history.
Observed on run 01M11JZVT7V507R56BCJJHZB1B; reproduced against the live
Venice API on claude-opus-5 and claude-sonnet-5 (four non-Claude models
stream index 0 correctly) and reported to Venice.

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

Both commands always registered the MCP client entry under the fixed
`mcpServers` key `fabro`, so users could not register separate Fabro
servers (for example production and testing) without editing the client
JSON by hand.
`--name <NAME>` now selects the `mcpServers` key. It defaults to `fabro`
for backward compatibility and rejects empty values. `fabro mcp init`
upserts only the named entry and preserves entries with other names, so
reusing a name updates that entry in place.
Closes#808

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.

Review cleanups for the tools/reasoning-effort model test change:
- Extract a shared parse_query_enum helper in the models handler in
place of two copy-pasted parse-or-400 match blocks.
- Collapse the duplicated basic-probe pipeline in fabro-llm behind a
single basic_probe core; name the shared EXPANDED_MAX_TOKENS budget.
- Pass &ModelTestArgs to test_models_via_server instead of threading
five of its fields positionally.
- Dedupe the two forwarding CLI integration tests behind a helper.
- Derive clap::ValueEnum for ReasoningEffort behind a feature-gated
clap dep (same pattern as MergeStrategy in fabro-types) so --help,
cli.mdx, and error output list effort values from the enum instead
of a hand-written list that drifts.

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.

GET /repos/{owner}/{repo}/installation returns 404 both when the App is
not installed for the owner and when the installation's repository
selection excludes the repository. The single-repository mint path
reported only the first cause, which misleads users whose App is
installed but not scoped to the repository. Name both causes and the
repository in the error.

Drop the startup retirement of the auth/code keyspace instead of
carrying one-shot cleanup code forever. The records it deleted are
inert: at most a handful exist at cutover, every binary (old or new)
rejects them within 60 seconds of issue via the expiry check, and
nothing reads the keyspace after the move to SQLite. The refresh-token
retirement keeps its original inline shape.

Cleanup pass over the pending-CLI-authorization move to SQLite:
- Extract a shared Database::retire_keyspace helper; the refresh-token
and authorization-code retirements are now one-line wrappers over it.
- Inline the startup retirement call (dropping the single-use wrapper,
its context-chain test, and the test_close_slate hook it required)
and run both SlateDB retirement scans concurrently. Error policies
are unchanged: authorization codes fatal, refresh tokens best-effort.
- Add a shared sqlite_row module with typed identity/timestamp row
decoding, used by both AuthorizationCodeStore and AuthSessionStore;
the session store's stringly Error::Other corruption errors become
the typed InvalidStoredIdentity/InvalidStoredTimestamp variants.
- Delete Repository::gc, which had no production callers left and was
kept alive by its own test; update the record-layer docs to match.
- Deduplicate the SQLite test-support bootstrap into sqlite_test_pool,
reuse issue() in the invalid-timestamp test instead of a copied
INSERT, and fold the new table into the existing existence-check loop
in the fabro-db schema test.

- Use a derived deserializer for RunTarget by making `None` an empty struct
variant, which keeps `deny_unknown_fields` strict without a hand-rolled impl
- Make clone_source_for_run the single owner of the empty-workspace decision
and drop the duplicated target checks in RunSession::new
- Collapse duplicated target/provider compatibility matches in admission and
start into single matches, using a strum-derived kind name for messages
- Drop the redundant git override in persist_create_run
- Extract a shared helper for the duplicated unavailable-integration test loop
