Fabro-sandbox carried its own SandboxEvent enum and a callback for it.
The run sandbox wrapped every lifecycle call to emit a start, completed,
or failed variant with its own clock, and re-described the driver's
create-time progress as snapshot events through an observer that lived
next to the run sandbox. The workflow then converted that enum to the
wire. The driver already reports every operation it performs, so the
enum was a second, hand-maintained copy of that stream.
The workflow now observes the driver's events directly. A run's sandbox
is created or attached with a driver EventContext whose observer is the
new SandboxEventBridge in the workflow's event module. The bridge turns
the driver's start, stop, and delete operations, its image pull inside a
create, and its snapshot builds into the workflow's SandboxLifecycle
events, stamping fabro's provider name so the run keeps recording
`local` rather than the driver's `host`. The pipeline emits the
initializing, ready, and failed events itself around bringing the sandbox
up, since that composite step — create, activate, prepare the workspace
— is the pipeline's, not the driver's. Fabro-sandbox emits no events of
its own any more; the run sandbox gained console_url for the ready
event, and a local sandbox can be created with an event context.
The wire keeps every name the CLI reads. Two families go: the cleanup
events, which only the server's manifest validation could have produced
and it passed no callback, and the git clone events, which nothing read
and whose facts the sandbox.initialized event and tracing already carry.
The ready event drops the cpu and memory fields no provider ever
populated. Daytona snapshot events now come from the driver's ensure
call, so a snapshot that already exists and is active reports nothing
rather than a creating-and-ready pair that did no work.

Fabro carried its own Sandbox trait long after every implementation
became a thin layer over the sandbox driver: one production type
implemented it, a delegation macro forwarded it, and each consumer crate
kept hand-written fakes of its thirty methods for tests. The trait
existed to be mocked, and the mocks pinned behavior that no provider
had — canned walk listings that ignored the traversal root, opaque
provider paths, activation failures with no lifecycle behind them.
There is now one sandbox type. RunSandbox keeps fabro's semantics — path
resolution against the run's working directory, the Bash exec policy,
git setup and push, credential refresh — as inherent methods over the
driver's exec, filesystem, search, and git facets, and every consumer
takes Arc<RunSandbox>. The directory, grep, and walk types are the
driver's own, re-exported from fabro-sandbox. The exec policy reports
the provider's measured duration rather than its own clock.
Tests script a sandbox through fabro-sandbox's MockSandbox: a struct of
fields (seeded files, the result every command returns, the platform,
a runtime directory) that hands out a RunSandbox over the driver's
scripted doubles and reads back what the code did — commands, timeouts,
environment, term stops, writes, deletes, existence probes. The
hand-written fakes in fabro-agent, fabro-acp, fabro-hooks,
fabro-workflow, and fabro-server are gone; the one wrapper a git
integration test still needs sits at the driver level, hiding a path
from a real Host sandbox. The refresh-ahead loop takes the refresh as a
closure so its schedule is tested without a sandbox at all.
The driver pin moves to the testing-crate stack head, which gained the
double behavior these ports needed: retention caps on scripted output,
canned walks narrowed to the requested base, upload and download on the
memory filesystem, and recorders for deletes, existence probes, and
term stops. One test that modelled a provider handing back opaque object
paths from a walk is removed: the driver contract has no such thing.

Three copies of the same mapping turned an environment into a sandbox:
Docker had its own options type built from the environment, Daytona a
config type with its own network enum and minute-and-gigabyte units,
and plugin kinds a third options type, each with its own spec builder,
constructor, and attach function, and the run spec had a variant per
provider carrying them. The mapping now runs once. SandboxOptions is
what any environment asks of any provider; options_from_environment
builds it, and one base spec carries the source, name, labels,
variables, resources, and network policy. Docker and Daytona are
overlays on that spec: Docker fixes its working directory, supplies the
default image, and pulls; Daytona replaces the source with the snapshot
it ensures from the same image or Dockerfile, fixes its working
directory and name, and sets the timers. The snapshot's content-addressed
name is unchanged, since the identity still hashes the image or
Dockerfile and the resources in whole gigabytes.
SandboxSpec has two variants, Local and Provider, and the worker and
the server preflight build the Provider one without knowing which kind
it is; provider_sandbox and attach_provider_sandbox connect any kind
through the single construction function and lay the repository out
where that kind keeps it. The per-provider constructors, the config
module, and the environment mapping module are gone, and the SDK
reference and the integration tests use the one constructor.

The plugin scenarios launched two executables fabro built itself,
`fabro-sandbox-host` and `fabro-sandbox-docker`, that only wrapped the
driver's providers in a stdio server the driver already ships as
`sandbox-driver-host` and `sandbox-driver-docker`. Fabro now finds the
driver's executables on PATH: CI installs them at the rev the workspace
pins, read from Cargo.toml so the plugins and the in-process providers
are one build, and a developer installs them the same way. The plugin
proof in fabro-sandbox skips without the executable unless the CI
environment forbids skipping; it was also never running in CI, which
ran it under `--run-ignored only` although it is not ignored, so the
job now runs it on its own.
The pin moves to the head of the sandbox-driver PR stack #9 through
#15: tag pins, classified git failures, the stop grace ladder, snapshot
ensure, the ownership scope, and the testing doubles, which the next
commits adopt. The `sandbox-driver-testing` crate joins the workspace
dependencies for them.

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.

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.

Fabro's Docker provider kind now maps onto the sandbox-driver Docker
provider instead of its own bollard implementation. Fabro keeps what is
its own: the clone decision and repository layout, the GitHub App push
credentials embedded in origin, git retry classification, the managed
labels that gate destructive operations, and the run-facing events.
- `clone.rs` performs fabro's clone over the driver `Git` and `Exec`
facets. An exact commit goes through the driver's pinned clone; a tag
pin runs fabro's init/fetch/attach sequence through `Exec` so the
fully qualified tag ref is the only revision consulted. Network
failures retry through `git_retry`, which now classifies driver errors
(exec output, provider retryability) and never replays an operation
whose outcome is unknown.
- `DriverSandbox` gains a pending-create state, a `RepoWorkspace` with
push-credential state, path resolution against the cloned working
directory, git lifecycle methods, image-pull progress mapped from
driver events, and an embedded terminal over the driver `Pty` facet.
- `docker.rs` builds the driver `SandboxSpec` (image, `/workspace`,
fabro labels, env, cpu/memory, network policy, run name) and attaches
by persisted container id, refusing containers without fabro's labels.
- Inventory, details, diagnostics, terminal, and reconnect run over the
driver: a `DriverInventoryProvider` lists by fabro's managed label and
projects `SandboxStatus` into fabro's inventory and details shapes.
- The bollard-based `docker.rs`, `provider/docker.rs`, Docker terminal,
Docker error variants, the `docker` cargo feature, and the bollard and
tar dependencies are gone. The Docker integration tests, the agent
shell test, the workflow artifact test, and the driver benchmark run
against the driver-backed sandbox.

SandboxSpec::Local and run reconnect now build a DriverSandbox over the
sandbox-driver Host provider instead of fabro's own LocalSandbox, which
is deleted. fabro_sandbox::local_sandbox designates the working
directory (created when missing, never removed), creates the Host handle
in a per-process registry, and learns the platform up front. A local
sandbox reports no provider id: it is its directory, which the run
record already carries, so reconnect rebuilds the handle over that
directory rather than by id.
The credential filter for explicit environment variables and the Bash
readiness probe now come from the exec layer and the driver's activate
helper. Test call sites move to the async constructor; test factories
that must stay synchronous share the parent session's sandbox handle.

SandboxProviderKind is now a validated string newtype instead of a
closed enum. The bundled kinds (local, docker, daytona) keep their
constants and a BundledProvider enum for the code paths that still
dispatch on them; any other well-formed sandbox-driver kind name is
accepted and names a plugin executable. EnvironmentProvider is gone:
environment settings carry SandboxProviderKind directly, and
is_clone_based is replaced by a workspace policy where local runs in a
designated directory and every other provider clones.
Server sandbox policy is keyed by kind. [server.sandbox.providers.<kind>]
accepts the bundled kinds with `enabled` and any plugin kind with its
launch settings (path, sha256, dev, args, env, inherit_env); bundled
kinds reject the plugin keys and a kind with no entry is disabled. The
OpenAPI schema, generated Rust and TypeScript clients, web settings
pages, and docs follow. The environments table drops its provider CHECK
enumeration in favour of the kind name rules so a plugin environment
can be stored.
Bundled-only code paths (run start, preflight, reconnect, terminal,
details) now fail with an explicit message for a plugin kind until the
driver construction function lands in the next step.

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.

Move the "which failures can happen before Starting" classification onto
FailureReason as an exhaustive predicate and use it for every
Runnable -> Failed transition, replacing the hand-maintained allowlist.
Give the pending-cancel precedence rule a single owner shared by the
worker launch and worker exit paths.
Test cleanups: share the Notify wait loop, server record fixture, and
post-failure assertions; simplify the pre-start test runtime's hold

Use the shared clone-based provider predicate and rely on the settings
resolver dropping disabled pull-request settings instead of re-checking
the enabled flag. List the new intent-lane error code in the OpenAPI
description, trim the acceptance tests to what they actually prove, and

Drop the unreachable active-run mismatch guard that was copied into
load_run_projection: the active-runs map is only ever inserted under the
handle's own run ID, so the check could never fire. Remove it from the two
pre-existing sites too and delete matches_run.
Trim install_in_memory_state to take only the committed projection, since
the event envelope duplicated last_seq and the inner scope only existed to
release the lock before the now-removed shared cache update. Add a From
impl so RunDatabase::build no longer hand-builds EventProjectionCache, and
rename projected_state_locked to match its projection_snapshot sibling.
In fabro-server, have reject_if_archived and ensure_run_exists read the
run summary row instead of replaying the full event history for inactive
runs; the summary is written in the same transaction as the event.
Fold the repeated store-reopen fixtures in fabro-store and fabro-server
tests into helpers, and fix a stale comment about the deleted shared
projection cache.

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.

- Load recovery candidates from the warm projection cache instead of
replaying each run's full event history, and check dispatch
eligibility before any I/O
- Extract the shared can_dispatch predicate used by both the recovery
scan and the worker dispatch loop
- Drop load_durable_run_status, now identical to durable_run_status
- Share parse_stored_run_id across the three stored-id decode sites
- Reuse push_order for the canonical run ordering in list_all and
list_by_statuses
- Replace the test-only queue clear accessor with the existing drain

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

deep-cloning the root workflow during collected validation, remove the
unused into_closure accessor, and dedupe test helpers.

Collapse the role-paired materializer error variants into
`Credentials`/`Checkout` tagged with a `CheckoutRole`, route both
checkouts through one resolve-then-prepare helper, and replace the
test-only clone-URL field on the production materializer with a
`GitRemote` resolver seam. A workflow source in the target's repository
now reuses the already-resolved credentials instead of minting a second
token.
Also inline the one-line workflow-source normalizer, drop the `as_str`
wrapper on the new kind enum, remove the unused migration constant, move
rather than clone scheduler fields, and deduplicate the web form's
ref-validity rule and per-kind copy into a single table.
