Nothing imports it any more: the Pebble glue lives in
fabro-pebble-sandbox, the server reaches run sandboxes through
sandbox_access, and Petri creates every run sandbox. The crate, its
test-support, its integration tests and every dependency edge go with
it. The `[server.sandbox.providers.<kind>.plugin]` settings stay: the
server still launches a plugin executable through them to attach to a
sandbox of a non-bundled kind.
AGENTS.md names the new crate and the direct-access pattern in place of
`RunSandbox`.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The sandbox handlers describe, list, download, upload, open a terminal
and build SSH and VNC access on the `Arc<dyn Sandbox>` the server attaches
to the run's record, with paths resolved against the recorded working
directory. Run Files holds the handle beside that directory and runs its
git through the driver's git facet and Fabro's exec policy;
fabro-workflow's sandbox git takes the same pair, and its
`GitCommandError` carries the driver's error. Run deletion deletes by id
through the provider scoped to the run's `petri.run` label, so a foreign
sandbox is refused and a designated host directory is left in place. Ask
Fabro wraps the attached, running handle. The legacy access shim is gone.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
`fabro-server/src/sandbox_access.rs` is the server's own path to a run's
sandbox: it connects the record's provider (the driver's Host, Docker and
Daytona providers in process, a plugin executable for any other kind),
keys ownership on the `petri.run` label Petri stamps on every sandbox it
creates, attaches by the recorded id, and for a host record designates
the recorded directory again when the id lives only in the worker's
registry. The Docker client resolves its endpoint from the same variables
Petri forwards to its plugin, so both meet on one daemon.
The doctor's Docker check and the Daytona credential probe move here with
`DaytonaCredentials`, and the `/sandboxes` inventory is rebuilt over the
driver's `list`, narrowed to sandboxes that carry Petri's run label.
Preflight asks the provider for its health instead of creating and
deleting a throwaway sandbox in Fabro's own shape, which no run uses; the
git retry policy behind the repository probe moves into run_manifest.
The callers still on fabro-sandbox's reconnect read their access through
a `legacy_provider_access` shim until they move.

Petri creates and owns every run sandbox through the sandbox driver, so
what Fabro still needs around a driver handle is the Pebble glue: the
Environment pebble's coding agent runs its tools through, the exec policy
(stop grace, working directory, StripAll, the termination mapping, the
redacted output tail), pebble's port routes over the driver's preview
URLs, the secret redactor, the path helpers, and a log rendering that
appends a failed command's redacted tail. This crate holds that glue,
moved from fabro-sandbox, over `Arc<dyn Sandbox>` plus a working
directory instead of `RunSandbox`, with a `MockSandbox` double behind
`test-support`.
`fabro exec` creates its host sandbox directly on the driver's Host
provider and activates it; Ask Fabro wraps the attached handle. Both
keep the provider alive beside the sandbox where the session's processes
are the provider's process groups.

Fabro's own DOT parser was left with one job after create-time compile
moved to Petri: walking a workflow's file references for the bundler and
the workflow-version store, and reading a name, a goal and two counts.
Petri's frontend parses the same language, so the parser goes and a small
crate reads the graph through Petri's.
`fabro-dot` is that crate: `WorkflowGraph::parse` over
`petri_frontend_attractor::dot` and its semantic model (defaults applied,
subgraphs flattened, chains expanded), `references(position)` as the one
walker over the static-reference vocabulary (each reference with its node
and position, file references checked to be template-free), and
`normalize_for_graphviz`, the re-emit of Fabro DOT with dotted attribute
keys quoted, which the SVG render needs. It sits beside `fabro-petri`
rather than inside it because `fabro-petri` depends on `fabro-workflow`,
which depends on `fabro-workflow-version`: the version store cannot reach
`fabro-petri` without a cycle, and the bundler should not pull the engine
in to read a graph.
Deleted: `fabro-graphviz`'s lexer, grammar, AST, semantic pass and
`parse_ast` (1,829 lines, plus the `nom` dependency); the DOT model in
`fabro-types::graph` (`Graph`, `Node`, `Edge`, `AttrValue`,
`shape_to_handler_type`), with only `ReferenceKind` kept, moved to
`fabro_types::reference`; `fabro-template`'s `visit_graph_references` and
the `GraphReference`/`GraphPosition` types, with the template-syntax rule
(`validate_static_reference`) kept there; the pull-request body's DOT
fallback summary, which was unreachable because the DOT source only
travels with the run spec whose display graph the summary already reads.
`fabro-graphviz` is now the render alone, over `fabro-dot`.
Parity: the old and new walkers were run over every `.fabro` and `.dot`
file in the repository (118) before the deletion. Every reference set is
identical. Five files differ in what Petri reads more correctly: a
backslash before a newline inside a quoted string is a line continuation
(four files, inline prompt text only), and a node named only by an edge
counts as a node (`test/edge_only_node.fabro`, 3 nodes rather than 2, so
the `fabro validate` snapshot moves). The checked-in bundles' shapes and
references are pinned by a snapshot in `fabro-dot`.

The rest of the change whose deletions the previous commit carries (its
`git add` stopped at an already-removed path): `fabro_types::RunGraph`
and the `fabro-petri` builder that reads it off the admitted graph, the
server's create, validate, preflight and render paths on Petri's check
alone, the consumers moved to the new shape, the OpenAPI `RunGraph`
schemas with their parity tests, the regenerated TS client, and the
docs naming Petri's diagnostic codes.

Each edge was checked with rg over the crate's sources outside its
test paths. fabro-cli keeps git2, regex, ulid, and shlex as
dev-dependencies for its integration tests. fabro-automation keeps
chrono, tokio, and tracing: its migrations compile into the crate
through #[path]. petri_testkit was already optional behind fabro-petri's
test-support feature and dual-listed as a dev-dependency. The workspace
loses the agent-client-protocol and AWS entries no crate references;
jsonschema stays for the fabro-api and fabro-tool tests. Cargo.lock
was refreshed by a plain build and only loses entries.

Artifacts reach the blob table through the hooks, so the POST on
/runs/{id}/stages/{stageId}/artifacts, its octet-stream and multipart
handlers, the RequireStageArtifact extractor, the client's upload
functions, and the generated TypeScript operation go. The spec loses
the operation, the multipart variant writeRunBlob never served, and
the batch manifest schemas; fabro-types loses ArtifactUpload, the
batch upload's only input type. Every list and download path stays,
and the server tests seed the artifact store directly to cover them.
fabro-server drops multer.

The engine prepares every run's checkout, so fabro's clone
orchestration, the per-checkout GitHub credentials, the run-branch
setup, the push retries, and the push policies had no production
caller. RepoWorkspace::plan still validates the clone request and now
refuses one that asks for a clone; initialize creates an empty
workspace root. SandboxWorkspaceLayout and snapshot_info stay: the run
record projection in sandbox_spec.rs reads them. The run tool
regression keeps its assertion (a child targets the parent's pushed
run branch) over a plain git fixture instead of the deleted setup. The
Docker, Daytona, and Daytona-wire clone layout tests go: they proved
only the legacy clone. fabro-sandbox drops base64, uuid, fabro-proc,
serde, strum, and sandbox-driver-daytona-config; chrono is test-only.

The failure classifiers, the handler and publish error builders, the
FailureDetail projections, and the LLM error conversions served the
deleted executor; Petri classifies failures now. Error keeps the
variants the create and read side construct, and the Engine variant
replaces the three-stage Stage shape. git_identity goes: the hooks
record git.identity through fabro_checkpoint. git.rs keeps the
observe, head, non-interactive push, and sync helpers the server and
fabro-manifest call, and loses the push half. fabro-llm loses the
failure signature hint whose only reader was the deleted classifier.
fabro-workflow drops regex, strum, and fabro-checkpoint.

Move the eight sandbox-driver pins from 64c14b8 to 07600aa, which is
lithoscomputer/sandbox-driver#23 (merged as 996e8a0). It absorbs one
commit: an idle Host sentinel now also reaps its own process group
when `kill -0` on its owning provider pid fails, alongside the fence
check. A Fabro worker that is killed rather than stopped no longer
leaves an idle sentinel behind for every exec it ran. The in-command
watcher still watches only the fence, so a running workload survives
its owner and a restarted provider can still fence it.
The change is internal to sandbox-driver-host; no fabro code moves.
Only the eight sandbox-driver sources change in the lockfile.

Petri 1fef017 pins the same lithos-llm and Pebble revisions Fabro's main
moved to in #883, so the workspace links one copy of each again. The
lockfile drops the second lithos-llm and pebble-agent/pebble-coding-agent
entries the merge carried while the two pins disagreed.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Move the lithos-llm pin from 55add459 to 43a42ac28e9d9bcf40a91abc02be4f12ca274ebb,
and the three Pebble pins from a39f43e to 67c9f48, Pebble `main`, which pins
that same lithos-llm revision so Cargo holds one lithos-llm crate. lithos-llm
`main` (ca19fac) is one commit further; that commit touches only its nightly
workflow, so this pin stays on the revision Pebble unifies with.
The `openai`, `anthropic`, `gemini`, and `openai-compatible` features are
gone upstream; each expanded to `runtime`, which `bedrock` implies, so the
four names leave the fabro-llm feature list. Every other manifest already
names `runtime`.
The catalog schema now names one adapter and many codecs per provider.
`adapter` defaults to `http`, `codecs = [...]` replaces `codec` and defaults
to `["openai-chat"]`, and the loader rejects the old `codec` key and the four
protocol-named adapter ids. Every inline catalog in tests and docs moves to
the new shape: the `openai-compatible` + `openai-chat` pair is dropped as the
default, `adapter = "openai"` + `codec = "openai-responses"` becomes
`codecs = ["openai-responses"]`, and the one test that swaps in a custom
adapter id now adds the line instead of replacing one. The settings
reference, the API schema's `Provider.adapter` description, and the SDK page
describe the new fields; the three `docs/superpowers/plans/` files that show
the old shape are dated, unchecked historical plans and are left as they are.
The implied agent profile for an operator provider that declares none used
to read the removed protocol adapter ids; it now reads the provider's first
codec (Anthropic Messages and Gemini map to their harnesses, the `bedrock`
adapter to Anthropic, everything else to OpenAI), with a test for the codec
path.
Absorbing the rest of the range: OpenRouter and Fireworks now ship enabled,
so the two fabro-llm tests that used OpenRouter as the disabled fixture use
`bedrock-openai`, and the docs and comments that said the two ship disabled
are corrected. The built-in catalog grew past 100 enabled model rows
(Vercel, TypeSafe, and the enabled OpenRouter and Fireworks rosters), so the
pagination shape test walks `page[offset]` to the last page instead of
assuming one page fits.
`cargo update -p` on the four crates also re-resolved a few already-locked
edges to match the lithos-llm lockfile: `windows-sys` 0.61.2/0.60.2 ->
0.59.0 under dirs-sys, errno, nu-ansi-term, quinn-udp, rustix,
rustls-platform-verifier, tempfile, terminal_size, and winapi-util;
`windows-core` 0.61.2 -> 0.62.2 under iana-time-zone; `errno` 0.2.8 ->
0.3.14 under signal-hook-registry; and `indexmap` 2.13.0 as a new public
dependency of lithos-llm. No package version was added or removed.

Petri a5906f6 records where each scope's sandbox ran (`scope.acquired`,
`scope.failed`) and how its lease was released (`scope.released`). The
projection folds the root invocation's records into `Run.sandbox`:
`initializing` from `run.started`, `ready` with the `RunSandboxInstance`
(the provider, Petri's `host` as Fabro's `local`, the provider's id, the
image and snapshot, the working directory) from `scope.acquired`, `failed`
from `scope.failed`; the retention outcome is kept in the fold state, since
the view has no field for it. Ask Fabro reconnect and `sandbox cp`,
`preview` and `ssh` reach the run's sandbox again.
A local reconnect designates the recorded working directory again when the
host provider does not know the id: the provider mints a registry-only id
for a workspace path too long for a path-derived one, and that registry
belongs to the run's worker. The stream listing redacts its items the way
the attached stream does, so a client that pages after a stream sees the
same items.
Pins move to Petri a5906f6 (run format 6, engine log v11, event contract
4). The attach stream snapshot is re-recorded with the new record and a
filter for the host provider's minted ids; `sandbox cp` reads an upload
back through the run's workspace, which is no longer the target folder.
Server scenario tests prove the projected instance on the host and Docker
providers.

Step 4 of the legacy executor deletion, fourth commit: with no writer
and no reader left, the legacy event log goes.
- `fabro-types`: `run_event` (`EventBody`, `RunEvent` and every props
struct), `EventEnvelope` and the `RunEventDetail*` types are deleted.
What the projection and the API still use moves out of the event
vocabulary: `AgentEventProps`, `AgentSessionActivatedProps`,
`AgentToolsAvailableProps`, `StagePromptProps`, `SessionCapability`
and the coding event names to `agent_props`; `RunNoticeLevel` and
`RunNoticeCode` to `notice`; `InterviewOption` beside the question
types; `RunRunnableSource` beside the run status. `Checkpoint` is
what Fabro records for a Petri run: `timestamp`, `current_node`,
`git_commit_sha`; the conclusion's stage summaries derive from the
projection's stages instead of the checkpoint's node maps.
- `fabro-store`: the Slate bridge (`RunDatabase`, the Slate `Database`,
`keys`, `record`, `EventPayload`) and the reducer (`run_state`) are
deleted. `Database` is the blob table and the run summary store over
one pool; the blob store is SQLite only; the run summary store keeps
the `runs` row a projector writes and lists, and finds the pull
request creation candidates over `platform_records`; `build_summary`
and `projected_usage` live in `run_summary`. The SlateDB dependency
is gone. Test fixtures build the store from its two SQLite stores.
- `fabro-workflow`: the `event` module (the `Event` enum, its
conversion, sink, emitter, redaction, stored fields and names),
`runtime_store`, `StageScope` and the legacy seeding test helpers are
deleted; the tests that seeded legacy runs read platform records or
a projection instead.
- `fabro-sandbox` owns `GitRetryReason`.
- The server builds the store without an object store; the legacy
`POST /runs/{id}/events` tests go, an interrupt answers
`interrupt_unsupported` in the tests as it does in the handler, and
the tests that read a run back through the Slate handle read its
projection or its platform records. The projection folds a block
that lands while the run is paused as the pause's prior block, and a
pause or unpause clears the pending control it answers; a control
request's check-and-append holds a per-run lock so two concurrent
cancels record one request.
- The CLI's final output is the response of the last stage that
produced one; the workflow tests read completed nodes from the
succeeded stages.
- The spec's `RunCheckpoint` carries the three fields the type keeps.
Still failing until the next commits: the CLI tests that seed runs
through `POST /runs/{id}/events` or wait for legacy event names, and
the two Ask Fabro resume tests (the sandbox instance gap).

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.

`fabro-hooks` ran the legacy executor's hooks; Petri's Attractor steps
run Fabro's hooks now, so nothing in the workspace uses the crate. The
engine freeze (the CI workflow, the two scripts, and the AGENTS.md and
fabro-petri README sections) guarded the engine half of `fabro-workflow`,
which the previous commit deleted.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Every run executes on Petri, so the in-process legacy executor goes:
`fabro-core` and, in `fabro-workflow`, the handlers, lifecycle, pipeline
execution, routing, retry, conditions, node handlers, steering, agent
memory, artifacts, checkpoints, command log, and the `start`, `resume`,
`retry`, `fork`, `rewind` and `timeline` operations. The two are deleted
together because the engine half of `fabro-workflow` was the only user of
`fabro-core` and `fabro-core` the only runtime of that half; neither
compiles without the other.
Kept in `fabro-workflow`, narrowed: the parse/transform/validate/persist
pipeline and `create`, `archive`, `validate` (workflow definitions still
come from DOT and settings); the run tools (`run_tools`, moved from
`handler/llm/fabro_tools.rs`) for Ask Fabro, `fabro exec` and Petri's
host tools; the pull request pipeline (`pull_request`, moved from
`pipeline/`, for the step 0 port); Run Files' diff helpers in
`sandbox_git`; `git_identity`, `usage_rollup`, `run_status`,
`run_materialization`, `web_search` and `workflow_bundle`.
Server: `RegistryFactoryOverride` becomes `execute_in_process`;
`RunAnswerTransport::InProcess` carries only the interviewer; the
interrupt endpoint answers 501 `interrupt_unsupported` and every pair
endpoint 501 `pair_unsupported` (status lists none); rewind, fork, retry
and timeline handlers and routes are removed; the command log is served
from the stage output blob; usage rollups accumulate from the settled
projection after an in-process run as after a worker exit.
Ported while here:
- `materialize_admitted_run` materializes the goal and drops a disabled
pull request block, as the legacy materializer did.
- A run whose admitted graph has an agent or prompt node is refused at
create when no LLM provider is ready (`fabro.model.no_ready_provider`);
a workflow of commands and gates needs no model and is admitted.
- The projection's question type falls back on the options, as the
interview adapter does, so a gate with edge-label options answers as
multiple choice.
Tests: the server scenarios (lifecycle, run completion, SSE, helpers)
run in process on Petri and assert Petri's stage labels and stream
names; the reconcile tests assert Petri's relaunch semantics; legacy
unit tests of the deleted executor are removed; three server unit tests
the removal took with it are restored; the pair fixtures go with the
pair feature. Petri test fixtures no longer name `[workflow] engine`.
Still red after this commit, all legacy consumers the next steps
delete or port: fabro-store's Slate/reducer fixtures and fabro-types
legacy JSON tests (step 4); server unit tests over legacy run events
(retry endpoints, list_run_events, artifacts, per-event pause/unpause,
run history activation, legacy sandbox fixtures) (steps 3-4); CLI tests
that parse legacy event envelopes, the legacy `events`/`attach`/`diff`/
`dump`/`inspect` snapshots, `run rewind`/`run fork`, the ACP and
git-identity workflow tests, and the runner tests that drive the legacy
worker by hand (steps 3-4); the web app's Petri fixtures still carry
`engine` (regenerate with `FABRO_CAPTURE_PETRI_FIXTURES` in step 4).

Petri's `scope_acquired` hook point and `SandboxOptions::lost_sandbox`,
which the sandbox checkpoints and their recovery build on.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Plan item F3.4. `fabro_petri::host_tools` adapts Petri's `HostTools`
capability to `register_fabro_run_tools`: every native agent session of a
run gets the tools the legacy worker registers, bound to the worker's
client and the run id, so a child run a stage creates is parented to the
Petri run. The tools run under the run's tool hooks, are recorded under
the stage, and reach sub-agents through Pebble's inheritance.
`RuntimeSpec::run_tools` installs the capability; the worker sets it when
the run's settings enable `[run.agent] fabro_tools` and the worker token
carries `agent:run_tools`, the legacy worker's gate. The server's
in-process test path runs without them, like the legacy one.
The identity the tools need is the run id alone; no run tool records a
stage on an effect, so nothing derives Fabro's `node@visit` label. A
context for another run gets no tools.

In-process tests over the memory store: every finish is committed on the
run branch with its identity trailers and recorded with its commit, the
run-end hooks reach Petri's local service through Fabro's wrapper, a
stage that fails on its own terms is committed and its failure route runs
on the committed files, a failed checkpoint records `checkpoint_failed`
with no route taken and a restart reports the run failed, and a
`[[run.hooks]]` hook blocks an agent's tool call through the forwarded
service, with the model told why.
Real-binary scenarios crash the server and its worker with SIGKILL: after
a durable finish the stage's commit is not repeated and the interrupted
stage reruns on its snapshot; a crash held before the commit reruns the
stage once; a crash held after the commit but before its record
reconciles the record from the snapshot repository; a deleted workspace
is restored; a failure route sees the same committed files after a
crash; a failed checkpoint fails the run and a restart leaves it failed.
Recovery selects the executions `inspect_run` reports incomplete, and a
run whose coordinator log is still empty is left to the worker's resume.
The worker's platform record endpoints get an API test and the generated
TypeScript client.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
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.

The projection folds Petri's public events (replay_since over the run's
stored records) and Fabro's platform records into the RunProjection the
API serves, row by row as VIEWS.md maps them. The stage key is the
execution and firing; the StageId label is node@visit, made unique with
the execution when two child invocations would share one. A stage's
first_event_seq is the milliseconds from the run's creation to its
visit.started, so the view built live equals the view rebuilt from the
records whatever order two logs' records were committed in.
The projector is the view pass and its wake-up. Records first: an append
returns before any view work; a pass reads what is committed, folds the
items past the committed positions, and writes the projection document,
the ordered stream (one stream_seq per Petri event or platform record,
with the item's own identity beside it) and the narrowed runs row in one
later transaction. Signals coalesce per run, a lost signal costs only
latency, the startup pass folds every run the view trails, and a pass
that races a platform record leaves the view alone and runs again. A
torn tail holds the view where it stands and reports the run incomplete
with the replay's error; inspect_run decides completeness once the run
recorded its finish.
The tests build the view live for the hello bundle, a command workflow
and a two-branch parallel workflow and compare it with the rebuild; drop
every wake-up and catch up by a signal and by the startup pass; crash
between the record commit and the view transaction and apply only the
suffix; restart the projector over child executions; and hold at a torn
tail.

A Petri run in the worker, and in the server under its test override, now
gets Fabro's platform adapters instead of the standalone defaults:
- `fabro_petri::interview`: Petri's `Interviewer` over the questions API
and the worker's control channel. A human gate's question is posted as
the `interview.started` event a legacy stage emits, keyed by an id
derived from Petri's identity (node, execution, firing, occurrence,
ask), so the API, the web app and Slack list it; the answer posted to
the questions endpoint reaches the control interviewer the adapter waits
on and is mapped onto Petri's answer. An expiry the gate reports is
completed as `interview.timeout`, a cancel as `interview.interrupted`,
and an auto-approved run answers itself. The hook points the read side
takes over are marked.
- `fabro_petri::secrets`: Petri's `SecretProvider` over the vault's token
entries, so `{{ secrets.NAME }}` resolves at spawn and is masked in every
record; a sensitive answer registers as a dynamic secret.
- `fabro_petri::blobs`: Petri's `OutputStore` over Fabro's `blobs` table,
through the server's blob store or the worker's client.
- The Fabro home the server resolved travels to the worker as
`--fabro-home`, so the skills step reads it whatever the worker's
environment says.
`engine::RunRequest` takes the interviewer, its observers, the secret
provider and the blob table from the caller; `interviewer::Unattended` is
gone.

Petri's `fabro-integration-p1` branch at 83345a8 adds
`Runtime::check_source`, the in-memory check entry point over a
`frontend::FileSource`, and makes `[workflow] engine` a known
`workflow.toml` key in its Fabro frontend, refusing any other unknown
`[workflow]` key with `unsupported.workflow_toml.key`.
Every `petri_*` entry moves from a0d2ceb to 83345a8. The lockfile changes
only the source line of the fifteen Petri packages; no other crate moves.

When `fabro run __run-worker` finds its run's stored spec names Petri, the
new `petri_worker` module executes it through `fabro_petri::engine` over
`HttpRunStore`, leased for a launch id the worker mints and logs at start.
`--mode start` loads the admitted graphs through the client's blob read;
`--mode resume` continues the run from its records. The worker's existing
services carry over: the control channel's cancel and SIGTERM/SIGINT cancel
Petri's root invocation politely, a lost control channel cancels the run
and is reported once it settles, and pause, unpause and steer are received
and ignored with a warning until their adapters land. The model client
comes from the worker's catalog and vault snapshot for the providers whose
credentials resolve, and the lifecycle events (`run.starting`,
`run.running`, then `run.completed` or `run.failed`) go through the client
as the legacy worker's do.
Scenario tests against the real binary: a command-only Petri run executes
in the worker a foreground server launched, its records reach
`petri_records` over the HTTP store and its lease ends with the worker; and
a run whose server and worker are both killed mid-stage resumes in a new
worker after the server restarts, with one `run.completed`.

`check` materializes a workflow version's bundle into a temporary directory
(`Runtime::check` reads files from disk), lowers it with the run's inputs
and launch, and returns the admitted graphs or Petri's diagnostics in a
shape the server maps onto Fabro's. `admission` keeps the admitted graphs
in the blob store, named on the run spec and verified by digest on load.
`runtime` assembles the same Petri runtime at create and at execution: the
Fabro frontend with the server's settings layer, the Attractor step kinds,
the model client as the PebbleClient capability so admission pins every
model. `engine` runs the admitted graph in the server process over
SqliteRunStore under the Fabro run id, with the standalone defaults, an
interviewer that fails any question, and cancel on a token, and derives the
outcome from inspect_run over the run's record.

The server answers the `/api/v1/runs/{id}/petri/*` endpoints from one
`SqliteRunStore` over its pool. `PetriRuns` in `AppState` keeps the
writer handle each worker opened, keyed by the run and the worker's
owner id, so the lease semantics stay the store's: the handle drops on
the worker's `release`, and every handle of a run drops when the server
observes the run's worker exit, in the subprocess wait path. Never by
timeout. A write from an owner with no held handle reopens only when
the lease row still names that owner, so a server restart or a lost
open reply recovers, and an owner the lease moved away from gets
`petri_stale_owner`.
Every endpoint is worker-scoped through the existing worker auth; a
new `RequireWorkerRunSegment` extractor covers the two-segment routes.
Store errors answer with a machine-readable code, the leased owner and
the conflict position under `meta`, and a backend failure's cause goes
to the server log rather than the worker.
A test drives a held worker through the scheduler, opens the run over
the API with its token, ends the worker, and sees the lease end.
