Register lazy Host, Docker, and Daytona factories for Petri execution,
fork, and prune. Share server provider configuration, preserve lease
fingerprints, and source Daytona credentials from the vault.
Remove built-in plugin setup and skip gates; add a release-mode worker
and prune regression to catch the failure that blocked nightly builds.

The host_plugin_ and docker_plugin_ variants ran each scenario under
Fabro's old plugin transport with the provider kinds `host` and
`docker-plugin`, which Petri's Fabro frontend rejects. Under Petri every
provider is already served by a sandbox-driver plugin, so those variants
test nothing distinct. A single docker_ variant replaces them: an
environment with provider `docker` on buildpack-deps:noble, created on
an isolated server, skipping without the sandbox-driver-docker
executable or a daemon with the image unless
FABRO_REQUIRE_SANDBOX_PLUGINS is set.

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`.

The TypeScript client's `RunCheckpoint` still carried the legacy
executor's resume fields; regenerating it from the spec gives it the
slim shape (`timestamp`, `current_node`, `git_commit_sha`). The CLI
test helpers that read a run's stream from its directory or the API
are named `run_stream_items`, so nothing but the dropped table's
migration history is still called `run_events`.

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).

Step 4 of the legacy executor deletion, third commit: the legacy event
API and every reader of it go, so that the next commits can delete the
event log, its reducer and the types beneath them.
The API:
- `GET /runs/{id}/events` pages the run stream only
(`PaginatedRunStreamList` by `after`); the legacy `since_seq`,
`before_seq` and `order` cursors, the `oneOf` envelope, the legacy
`EventEnvelope`, `PaginatedEventList`, `RunEvent`, `EventSeq`,
`AppendEventResponse` and `RunEventDetailResponse` schemas,
`POST /runs/{id}/events`, `GET /runs/{id}/events/{seq}` and
`GET /runs/{id}/stages/{stageId}/events` are deleted. `GET
/runs/{id}/attach` and `GET /attach` frame `RunStreamItem`s only.
- The Rust and TypeScript clients regenerate; the removed models leave
the TypeScript package.
The readers:
- `fabro-client` drops the legacy run event listing, tail and attach
methods and `RunEventStream`; `list_run_stream_until` bounds a stream
read.
- `fabro-tool`'s `fabro_run_events` lists, searches and details the run
stream: `after` is the exclusive `stream_seq` cursor, `event_id` the
item's id, filters match the item's name and `recorded_at`.
- `fabro-dump` writes the stream to `events.jsonl`; `fabro dump` reads
it.
- The CLI's progress renderer keeps only what the run stream drives:
the legacy event conversion, the sandbox and setup displays and their
styles go. `fabro system events` prints stream items.
- The server's demo mode folds its agent fixture straight into the
session projection and answers the attach stub with a stream item;
the demo stage events endpoint is gone.
- The web app: every run is a Petri run. The legacy event hooks,
renderer props, stage popover summary, run phases derivation and
live-event payload handling are deleted or ported to `RunStreamItem`;
toasts and board refreshes read the stream's platform records.
- Tests: the legacy API round trips and pagination tests are deleted;
the CLI's MCP, attach and system event mocks serve stream pages; the
CLI test helpers read stream items.
Still failing until the later commits: the CLI tests seeded through
`POST /runs/{id}/events`, the server tests over the legacy store, and
the legacy type tests.

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.

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.

sandbox-driver PR #9 removes the check that a plugin's declared kind match
the configured one: an operator who configures a path and pins its
checksum has already chosen the executable, so the configured kind is
fabro's name for whatever it serves. With that in the driver, fabro no
longer needs plugin settings on a bundled kind to reach Docker over the
wire. Bundled kinds reject plugin keys again, `connect_provider` links a
bundled kind in-process and launches everything else, and the CLI
scenarios run the Docker executable under the non-bundled `docker-plugin`
kind. The driver pin moves to the PR head until it merges.

Closes the sandbox-driver adoption: any provider a sandbox-driver plugin
executable serves can now host a fabro run, and fabro's own bundled
providers can be served the same way.
- `SandboxSpec::Plugin` builds a normalized driver spec from the
environment (image or Dockerfile source, or a provider-managed
directory; resources; network policy; labels; env) and lays fabro's
repository checkout out inside the provider's working directory. The
layout is recorded on the run through the new `workspace_layout` trait
method.
- Plugin settings on a bundled kind (`[server.sandbox.providers.docker]
path = ...`) serve that kind out of process through the driver's
executable; the config layer no longer rejects them.
- `ProviderAccess` carries the server's provider settings and the vault's
Daytona credentials to every reconnect: run resume, sandbox details,
terminals, previews, and the worker's start path. The worker receives
the settings through `StartServices`. No "plugin not wired" errors
remain.
- The CLI worker requires GitHub credentials only when a repository will
be cloned; a `none` target on a clone-based provider creates an empty
workspace and needs none.
- fabro-db tracks its migrations directory so a new migration file
recompiles the crate; the environment provider migration had been
silently missing from stale builds. Environment store 500s now log
their cause.
- The CLI workflow scenarios run against `host-plugin` (the driver's
Host executable under the non-bundled `host` kind) and `docker-plugin`
(the bundled `docker` kind served over stdio), each on an isolated
server, printing the server log on failure. A live Daytona gate runs
the native git clone over the JSON-RPC wire. A new CI job runs the
plugin scenarios and the driver-backed Docker integration tests with
the plugin executables built.
