Petri judges a workflow at admission, so Fabro's lint rules go:
`fabro-validate` (its 35 rules and the `LintRule` trait) is deleted, and
with it `fabro-acp` (only a rule and two legacy executor tests used it),
the model-resolution transform, the legacy `create`, `compile_create_run`
and `materialize_create_run` stages, and `fabro-graphviz`'s `condition`
and `fidelity` modules. `Diagnostic`, `RelatedDiagnostic` and `Severity`
move to `fabro_types::diagnostic`, the one shape every diagnostic takes.
Validation is now the same question the create handler asks. A new
server module, `petri_check`, builds Petri's check request from a
workflow bundle and the run's settings (every workflow of the bundle at
its bundle-relative path, the inputs, the run variables, the launch),
runs the check, and maps the diagnostics; Fabro adds one rule of its
own, `fabro.model.no_ready_provider`, refusing a model node when no
provider is ready. Admission, the validate and preflight endpoints and
the offline `fabro validate` all go through it:
- `validate_prepared_manifest` runs Fabro's structural pass (parse and
transform, whose diagnostics stay) and then Petri's check, on the
blocking pool from the handlers;
- the offline `validate_manifest` checks with no model client and with
an unbound input as a warning (`CheckRequest.unbound_is_warning`), so
a workflow validates before its inputs exist; a collected workflow
before upload checks with unbound inputs as errors, as before;
- preflight resolves each LLM node's selector against the ready
providers and the catalog for its probe, as the deleted transform did,
and no longer probes a model Petri refused;
- the graph render endpoint needs only the structural pass;
- a run manifest now carries its `[run.goal] file`, which Petri reads
from the bundle as it does for a version.
The transforms keep the authored model selector (`sonnet` stays
`sonnet`): Petri pins the catalog model in the admitted graph, not in
the graph Fabro displays or in the settings snapshot. Tests assert that,
and the CLI's validate, preflight and graph snapshots carry Petri's
diagnostics (`attractor.no_start`, `attractor.undeclared_node`,
`attractor.bad_on_failure`, ...) in place of the lint rules' text.
Known gaps, Petri's side: a `workflow.toml` whose `[run.environment]`
names an environment the server catalog defines but the file does not
is refused (`unsupported.workflow_toml.run.environment`), as admission
already refused it; an unbound input inside an included template
partial is a render error rather than the unbound-input warning.

`fabro-mcp` held two things after the legacy executor went: the mapping
from Fabro's MCP server settings to the servers pebble starts, which
only `fabro exec` still uses, and a stdio MCP client the tests of
Fabro's own MCP server speak through. The mapping is now
`fabro-cli`'s `mcp_servers` module and the client its test support's
`McpStdioTestClient`; the crate is deleted. Its `config` module was a
re-export of `fabro_types::settings::run`, which callers import directly.

The legacy executor replayed a run from a checkpoint; Petri resumes a
run from its records instead, and the checkpoint timeline, rewind, fork
and retry were the operations that replay carried. The server dropped
their handlers with the executor; this removes the rest:
- the API spec's `/runs/{id}/retry`, `/rewind`, `/fork` and `/timeline`
paths with the `ForkRequest`, `ForkResponse`, `RewindRequest`,
`RewindResponse` and `TimelineEntryResponse` schemas, and the
generated TypeScript models;
- `fabro rewind` and `fabro fork` (with the checkpoint timeline printer
and the repo-origin check only they used), their reference pages and
the checkpoints guide's rewind and fork sections;
- `fabro-client`'s `rewind_run`, `fork_run` and `run_timeline`;
- the web app's Retry action on the run list and the run page.
`Run.retried_from` stays on the run type: a run that was retried before
the cutover would still name its source.

Delete `Engine`, `RunEngine`, `[workflow] engine`, `[server.execution]
engine`, `FABRO_SERVER_ENGINE` and `fabro server start --engine`. The run
spec records what Petri admitted as `admission: PetriAdmission`; the
create handler always admits through `Runtime::check`; `execute_run`
always launches the Petri worker (or executes in process under the test
override); the CLI runner takes only the Petri worker path, and its
legacy control arm, artifact uploader, signal pause handlers and
credential helpers go with it. The CLI's `attach` and `events` read the
run stream only.
Two gaps this surfaced are closed here: the check adapter binds the
server's run variables as Petri compile variables (`{{ vars.* }}` in a
prompt no longer fails admission), and deleting a run removes its Petri
records, lease, platform records, projection and stream.
Tests: the config engine tests are replaced (an engine key is unknown),
the API round-trip test covers `PetriAdmission`, the server and CLI
Petri scenarios drop their engine settings, and the API tests that read
legacy event names now read the run stream or the session events. The
remaining red tests are fixtures and scenarios of the legacy executor
and the legacy event store (`fabro-store` `slate` and `run_state`,
`fabro-types` legacy `run.created` JSON, the server's handler-registry
scenarios, the CLI dry-run snapshots), which the next steps of the F4.3
series delete or port.

Re-pin lithos-llm to 55add4596b861a0623d00c3a54aa5c147c8d504b and
pebble to c91810fe51aece80359b9cd8efea971af0c46925, where token usage
and cost travel together as Usage { tokens: TokenCounts, cost:
Option<Cost> }. Fabro now carries that one type everywhere it used to
carry BilledTokenCounts, BilledModelUsage, UsdMicros, or a token count
beside a cost_usd_micros.
fabro-types: billing.rs is usage.rs with ModelRef, ModelUsage { model,
usage }, sum_usage, and usage_is_empty; billing_rollup.rs is
usage_rollup.rs with ProjectionUsageStage, ProjectionUsageByModel,
ProjectionUsageRollup, and usage_rollup_from_projection. Every usage
field is named usage: StageProjection.usage and usage_by_model,
Outcome<Option<ModelUsage>>, stage.completed and stage.failed usage and
usage_by_model, prompt.completed usage, run.completed and run.failed
usage (total_usd_micros is gone), Conclusion.usage, StageSummary.usage,
Run.usage. RunSize buckets by Cost.
fabro-workflow: model_usage_from_llm prices tokens from the catalog with
a Catalog cost source, with_reported_cost keeps a provider cost, and the
pebble handler's stage_usage groups pebble's accounts by model and sums
rows with Usage::saturating_add, so a total has a cost only when every
priced part was priced. The store fold's live usage is the agent's
usage plus its descendants'.
API: the OpenAPI spec deletes BilledTokenCounts, BilledModelUsage,
CompletionUsage, CompletionCost, TokenUsage, and RunBillingSummary,
adds TokenCounts, Cost, Usage, and ModelUsage, and renames every
billing schema, property, tag, path, and operation to usage. fabro-api
reuses lithos-llm's and fabro-types' types through with_replacement,
with a round-trip test per replacement.
Old stored runs get no migration: their pebble events in the old shape
read back with zero usage, and their rebuilt projections lose agent
usage.

Since #852, `fabro exec --verbose` only turned on the request/response
middleware on the LLM client and no longer printed tool calls, tool
results, or the transcript. Pebble #18 gives pebble-cli-core rendering
options, so `--verbose` now runs the prompt through
`run_prompt_with(..., RenderOptions::verbose())`: each tool call's
arguments and result in full under its `[tool]` and `[result]` lines,
plus the transcript. The middleware is enabled as before. Without the
flag the renderer gets the default options, so the output is unchanged.
The twin shell test now scripts the tool call and the final answer as
two turns, so the answer on stdout is the scripted one rather than the
twin's fallback echo, and it asserts that stderr carries no result,
reasoning, or verbose blocks. A new twin test runs the same prompt with
`--verbose` and asserts the tool and result blocks and the request dump.

The provider probe runs inside the isolated server, which never sees the
test process environment. The test used to store `OPENAI_BASE_URL` in the
vault, and cd74013d0 dropped that entry without replacing it, so the
server probed the real OpenAI API with the namespace as its key and the
doctor reported the provider as failed. The server settings now repoint
the `openai` provider at the twin through the operator `[llm]` overlay.

Resolve conflicts between the metadata-branch removal and the
sandbox-driver adoption on main:
- fabro-sandbox docker.rs, sandbox.rs, daytona/mod.rs: take main's driver
rewrite. The Sandbox trait is gone, so the PR's push_token_source
removal now applies to RunSandbox instead; drop that accessor and the
RepoCredentials::source helper that only served it.
- run_metadata.rs: keep deleted. Main's edits there were adaptations to
the driver API and the run git identity field.
- lifecycle/git.rs, finalize.rs: keep the PR's removal of metadata
snapshots and write_finalize_commit; carry main's RunSandbox,
GitRetryPolicy, git_identity, local_sandbox, and test catalog changes.
- sandbox_git.rs: take main's version and drop the shadow_sha parameter
and Fabro-Checkpoint trailer.
- git_integration.rs: remove meta_branch from the new git identity test.
- Cargo.toml: main's dependency set with fabro-dump kept as a
dev-dependency.
- checkpoints.mdx: keep both the git identity paragraph and the durable
execution state section.

remote_workflow_run_starts_once_create_leaves_submitted_and_failures_do_not_refetch
lived in cmd/create.rs but drove fabro run in four of its five
iterations and asserted the start call, which is fabro run's contract.
Split it: cmd/create.rs keeps the single create invocation that must
leave the run submitted without starting it, cmd/run.rs owns the
run-driven success and failure iterations, and the workflow and remote
repository fixtures move to the shared command test support module.

For --workflow-git selections, target resolution ran before the remote
workflow ref was verified to exist. On Docker and Daytona environments a
path target that is a GitHub checkout is observed via
observe_git_run_target, which may silently push the attached branch, so
a typo in --workflow-ref produced a remote side effect with no run
created. Resolve the remote workflow after parent and environment
validation but before target observation, restoring the pre-existing
workflow-then-target order, and cover it with a caller checkout whose
unpushed branch must stay unpublished.

Remove validation that ran twice on the same inputs: clap already
enforces the flag co-occurrence rules, and the native Git layer no
longer re-checks selectors, branch names, refs, and commit SHAs that
selection parsing already validated. Remote selector shape rules now
delegate to the shared WorkflowPath validator.
Reuse fabro_proc for the process-group kill and liveness probe instead
of calling nix directly, dropping the extra nix features. Fold the
duplicated branch/tag candidate derivation into one RefCandidates type,
label each Git command explicitly instead of inferring it from argv,
hoist the duplicated workflow resolver call in create_run, and merge the
two directory target arms now that the default is just the caller path.
Share the run-argument parser and workflow/commit fixtures across the
unit tests through a test_support module, drop an integration test that
duplicated one cell of the cross-product test, and make the malformed
slug vectors assert the clap rejection they exercise.

A run now resolves a single author and committer identity once, after its
GitHub credentials are selected and before anything can commit, and uses it
for every commit it creates. Resolution order: a complete explicit
`run.git.author`; the run's GitHub App bot account
(`<slug>[bot] <id+slug[bot]@users.noreply.github.com>`); the authenticated
user of the run's PAT; the generic `Fabro <noreply@fabro.sh>`. A partial
explicit author overlays the fields it supplies. Only the selected
credential is consulted; a failed lookup is a setup error. A standalone
installation token falls back to the generic identity with a warning.
The resolved identity is carried on `RunOptions` and `EngineServices`,
recorded as a `git.identity.resolved` event and `RunProjection.git_identity`
so resume reuses it, and exposed through the run state API. Engine
checkpoints and metadata commits read it through `RunOptions::git_author`.
Every workflow execution path receives it as `GIT_AUTHOR_NAME`,
`GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_NAME`, and `GIT_COMMITTER_EMAIL`, applied
last so it wins over inherited host variables and `[run.environment]`
entries: prepare steps, command stages, native agent shell tools, and ACP
launches. The identity is injected even without a Git origin, and the old
local `git config user.*` write is removed.
fabro-github gains `GET /user` and `/users/{slug}[bot]` lookups with mocked
tests for success, unauthorized, malformed, and transient cases. Real-Git
integration tests commit in the primary checkout, a clone, and a fresh
repository under conflicting local config, `[run.environment]`, and host
variables, and prove concurrent runs do not leak identities. CLI workflow
tests cover host script stages and ACP launch env through `fabro run`.
Docs and generated option metadata now describe the credential-derived
defaults instead of the stale `fabro`/`fabro@local` values.

Standalone fabro_run_create ignored the environment's provider and always
produced a Git target or failed, so a Local environment with no explicit
target was rejected by admission and a directory without Git metadata
hard-failed, while fabro run derived a folder target and a none target
for the same inputs.
Move the CLI's provider-aware derivation into fabro-manifest as a shared
helper with a typed error, and have the standalone adapter look up the
selected environment and call it. The helper also distinguishes a failed
remote query from an unpublished commit, so an offline ls-remote no
longer reports "push the commit and try again" when the branch is
already on the origin.

Main merged the sandbox-driver adoption (#849) in a later form than this
branch was stacked on: the driver's own exec types replace fabro-sandbox's,
shell quoting moved to fabro-util, the sandbox lifecycle collapsed, and the
driver's events are stored as run events. This branch had deleted
`fabro-agent` and put the coding agent, the environment adapter, and the
steering hub on pebble.
The resolution takes main's sandbox API and re-applies pebble on top: the
`RunSandbox` `Environment` adapter moves to `pebble_environment.rs` (main's
`environment.rs` is the sandbox spec) and runs commands through `ExecSpec`
and `ExecControls`, feeding pebble's output sink from the driver's; the
driver-era `sandbox.*` names leave the known-event list, as on main, so a
stored event with that name and no driver shape is `Unknown` rather than an
error; `program_exit_code` matches pebble's non-exhaustive termination; the
Docker and Daytona smokes use main's constructor and credentials; the
remaining `fabro_agent` paths point at fabro-sandbox.
Pebble's `mcp` feature pins sandbox-driver, and the preview-url trait
objects only cross when both sides name one revision, so pebble moved to
main's `a92c0db6` (lithoscomputer/pebble#10) and fabro pins that pebble
revision until it lands on pebble main.

Step 3 of .ai/plans/pebble-absorbs-embedder-concerns.md, pinning pebble
6cdb30a with its `mcp` feature.
Pebble starts the stage's MCP servers while the agent is built, registers
their tools under `mcp__{server}__{tool}` with `ToolSource::Mcp`, and
closes them with the agent, for all three placements: a child of the run
worker over stdio, a server over HTTP (streamable or SSE), and a server
launched in the run sandbox and reached through the sandbox's preview
URL. `fabro_mcp::pebble::pebble_server` maps `McpServerSettings` onto
pebble's `McpServer`, keeping fabro's `/sse` path for sandbox-hosted SSE
servers; `RunSandbox::port_routes` hands pebble the driver's `PreviewUrls`
facet as the route to a sandbox port. The stage's event sink mirrors
`McpServerReady` and `McpServerFailed` onto the run's `agent.mcp.ready`
and `agent.mcp.failed` events, as it mirrors `RouteFailover` onto
`agent.failover`, and stores no second copy of a mirrored fact.
Deleted: `sandbox_mcp.rs`, the MCP branches of `pebble.rs` and `fabro
exec`, and fabro-mcp's client, connection manager, HTTP helpers, and SSE
transport, whose tests moved to pebble. fabro-mcp keeps the settings
re-export, the mapping, and a stdio client behind `test-support` for the
tests of fabro's own MCP server. `fabro exec` reports each server's
outcome from the agent's snapshot. The Daytona Playwright live test now
drives the sandbox-hosted server through an agent.

SandboxSpec had a Local variant beside the provider spec, and a local
sandbox was created by hand over a bare Host provider: no workspace, no
provider connection, its own reconnect, and its own push rule for the
designated directory. The local kind is now one more SandboxSpec:
SandboxSpec::local names the directory on a HostDirectory spec with a
skip clone, and provider_sandbox builds it like a plugin kind, creating
the directory when missing since the Host provider requires it to exist.
Every RunSandbox carries a workspace; a handle wrapped as is gets the
workspace of its own working directory.
The push rule is one rule for every checkout: a checkout fabro cloned
pushes with the credentials it was cloned with, and any other checkout
pushes when it has an origin, with whatever credentials it carries. A
local run therefore pushes the same way before and after a resume;
before, a reconnected local sandbox carried an attached workspace that
never pushed while a fresh one did.
Reconnect uses the recorded id for every kind. The recompute of a local
id from its directory, kept for records written before directories had
ids, is gone, and test fixtures that wrote made-up local ids derive them
through test_support::local_sandbox_id instead. A local run's record now
carries its workspace layout like every provider-chosen directory, and
the sandbox.initializing event precedes the driver's create events for
local as for every other kind.

A dry run's stored history ends with the sandbox stop, which now carries
the driver's event instead of fabro's provider and duration fields.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The attach snapshots now carry the driver's create events, whose event
source and operation ids are minted per process and whose durations run
to the nanosecond, and the local sandbox's id is derived from a temporary
directory; the shared snapshot filters cover all three. A local sandbox's
ready event no longer names that id: the record already holds the
directory, and the id is nothing a person reads.

A bridge translated the driver's events into thirteen lifecycle variants
of fabro's own (start, stop, and delete phases, image pulls, snapshot
builds) and dropped everything else the driver reported, pairing an image
pull's first progress report with the create's completion to invent a
duration. The driver's event is now stored as the run event itself, under
a name derived from it: subject, action, and phase (sandbox.stop.completed,
sandbox.create.progress for an image pull, snapshot.create.started), or
<subject>.state and <subject>.notice. Every operation the driver performs
on the run's sandbox lands on the run, including creates and state
observations the bridge skipped. The CLI reads image pulls and snapshot
builds from the driver's event for its setup progress and pretty output,
the thirteen variants and their props go, and a run stored under the old
names still reads as an unknown body. Checkpoint file numbers in a dump
shift because the run records more events before each checkpoint.

Both sides rewrote the same crates. This branch replaced fabro's sandbox
layer with the sandbox driver: one RunSandbox, no Sandbox trait, driver
events consumed directly, MockSandbox over the driver's doubles. Main
replaced fabro's LLM layer with lithos-llm: fabro-model deleted, the
catalog and provider ids from lithos, credentials through the lithos
CredentialProvider, clients built with build_client.
Every conflict was one of those two renames meeting in an import list or
a signature, so the rule was mechanical: sandbox names resolve to this
branch, LLM names to main. Where main's newer code still used the old
sandbox API — new session tests over Arc::new(MockSandbox), the SDK
example's LocalSandbox, test fakes typed as Arc<dyn Sandbox> — it is
ported to RunSandbox and the mock helper. Where this branch still used
fabro-model or Client::from_source, main's replacement stands. One
combined future in the CLI runner crossed clippy's size budget and is
boxed at its call.

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`.

The `daytona` provider kind now maps onto the sandbox-driver Daytona
provider instead of fabro's own SDK client. Fabro keeps what is its own:
the HMAC-named snapshot built from the environment's image or Dockerfile,
the explicit 120 minute auto-stop default, the managed labels that gate
destructive operations, the clone decision and layout, and push
credentials. The driver creates the sandbox, clones natively, and serves
exec, files, search, terminal, SSH, preview, and VNC through its facets.
- `daytona.rs` builds the driver `SandboxSpec` (snapshot source,
`/home/daytona/workspace`, labels, timers, network policy, run name),
ensures the snapshot through the driver `SnapshotProvider`, attaches by
persisted id with fabro's label guard, and probes credentials through
the provider health check under fabro's 20 second budget.
- `DriverSandbox` gains a create plan that settles the spec right before
the provider call, records the snapshot a sandbox came from, and
reports the provider console URL on `Ready`.
- Terminals use the driver `Pty` facet; the server's SSH, preview, and
VNC endpoints use the `SshAccess`, `PreviewUrls`, and `Vnc` facets
through the driver-typed reconnect. The preview endpoint now answers
for every provider with a preview facet, so the local sandbox returns
its loopback URL.
- Daytona credentials travel as `DaytonaCredentials` built from the
vault key plus configured URL and organization; nothing reads the
process environment implicitly. The inventory registry uses the shared
`DriverInventoryProvider`.
- The SDK-based `daytona/mod.rs`, `provider/daytona.rs`, the Daytona
terminal, the `daytona` cargo feature, and the direct daytona-sdk,
git2 (in fabro-sandbox), tungstenite, and rustls dependencies are
gone. The live Daytona tests run against the driver-backed sandbox.

The OpenAPI spec adopts the lithos request, response, content part,
tool, usage, and cost schemas. The completions endpoint returns the
lithos `Response` JSON verbatim and SSE carries lithos `StreamEvent`s
verbatim. The models and providers endpoints serve the fabro-types
catalog views, and the install and model-test flows probe providers
through fabro-llm.
The CLI builds its catalog from the operator overlay, drives `fabro exec`
through the server gateway adapter, and parses reasoning effort with the
shared controls. The web app reads content parts as lithos-tagged
objects. The TypeScript client is regenerated.

When `fabro run` or `fabro create` omits `--environment` and the server
has no environment named `default`, the CLI previously failed with only
"could not retrieve environment `default`". It now lists the server's
environment catalog in the error so the user can pass an explicit
`--environment <id>` or create the missing `default` entry. Explicit
`--environment` lookups keep their existing not-found message.
Adds `Client::list_environments` to fabro-client for the catalog read.

Quality pass over the intent-producer changes, no behavior changes
intended:
- Move the TOML->JSON scalar conversion into fabro-types as
toml_scalar_to_json_value, next to its inverse, with typed errors and
round-trip tests; the CLI now calls the shared helper.
- Reuse goal_layer_from_args for --goal/--goal-file resolution instead
of a second copy of the exclusivity check and cwd anchoring.
- Delete the dead run_manifest_args helper and the test that kept it
compiling; preflight_manifest_args is the remaining real builder.
- Make run_target_for_environment a pure (provider, cwd) -> target
mapping using is_clone_based(), warning at the call site, and default
the environment id from DEFAULT_ENVIRONMENT_ID instead of a literal.
- Resolve the parent run and retrieve the environment concurrently.
- Drop the ResolvedCommandSettings pass-through struct and the
duplicated parse-error mapping in the project settings presence read.
- Share the environment/workflow-version/git test mocks from the cmd
test support module instead of three per-file copies.
