Move supplied-content packaging into fabro-manifest beside the checkout
collector, and narrow the injected seam to a packager that returns the
dependency-ordered closure so ClientBackend registers versions with the
client it already owns.
Validate the tool input once through a ValidatedWorkflowVersionCreate
newtype, matching the other tools, instead of re-validating at three
layers. Reuse the fabro-types unique-map deserializer and the shared
"not available" error helper, derive budget messages from the limit
constants, and render the tool result through the shared summary+JSON
path used by sibling tools.
Share one extension dispatch between WorkflowLocation::resolve and
from_exact_path, compute the bundler's normalized reference once, key
path-collision checks by a Cow so the canonical exact check no longer
allocates, and log the full packaging error chain before returning the
curated tool message. Replace the hand-rolled axum test server with
httpmock and declare the new unicode dependencies at the workspace.

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.

Pebble's command line is a library now. `fabro exec` builds its agent as
before, with fabro's client, sandbox, MCP servers, skills, search, and
redaction, and hands it to pebble's session: the events rendered as they
happen, the answer on standard output, the summary after it, the agent shut
down for the reason the prompt ended with, and the terminal approval prompt
for tools the permission level does not allow. Fabro's own progress printer,
approval prompt, summary, and MCP report are gone. The event stream of
`--output-format json` stays on standard output. Standard output now carries
the final answer alone rather than every assistant message; `--verbose` no
longer prints tool results, since the session's renderer shows tool failures
only. The lockfile moves tempfile to the version pebble pins, and the SQLite
backup migration uses the replacement for the constructor that version
deprecates.

Pebble's `SteeringBus` now owns the map of live sessions, the buffer for
steers that arrive between sessions, fan-out of steers and interrupts, the
close-the-door detach, and the hold that keeps a paired session open. The
hub keeps what only fabro knows: pair records, principals, stage ids, and
the run events that put bus activity on the run's stream in the order its
consumers expect. `PebbleControlHandle` is gone, since the coding agent's
control handle is a bus session natively; the ACP session joins the bus
through a small adapter and carries pebble's steering message end to end,
so a human steer keeps its author on the ACP `agent.steering.injected`
event. A pair message that evicted an older steer is now accepted and the
eviction recorded, where before it was queued and reported as refused.

Pebble now folds a session tree's events into a serializable projection
with a per-prompt delta. Fabro's stage projection stays as it is: it is the
wire contract the API serves and is applied to incrementally, so pebble's
value cannot stand in for it without changing that contract. The new
parity tests replay one retained session across two stages through both
folds and pin a stage's live account to the prompt delta pebble reports,
its subagent rows to pebble's, and a stored projection to a replayed one.

Steps 4, 6, and 7 of .ai/plans/pebble-absorbs-embedder-concerns.md,
pinning pebble fc907a1 with its `search-providers` feature.
The sandbox's `Environment` adapter uses pebble's `environment::support`
for the glob grammar check, the tree-order sort of a listing, and the
capture accounting, in place of its own copies; the adapter itself stays.
The stage reads the compactions a prompt performed from the report, as a
breakdown of the usage it already billed. `web_search.rs` keeps the
vault-backed credentials and the Brave-over-Venice preference, and hands
pebble's `Brave` or `Venice` provider a fabro HTTP client; the providers
and their tests are pebble's now.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Steps 5 and 8 of .ai/plans/pebble-absorbs-embedder-concerns.md, pinning
pebble 49da137.
Agent stages and `fabro exec` ask pebble for the profile's instruction
files from the repository root down to the working directory
(`MemoryDiscovery::from_git_root`), which fabro lacked: it read the
working directory alone. Skill directories are pebble's to resolve too:
the user's skills directory, then `.fabro/skills` and `skills` under the
repository root. Prompt stages keep reading the working directory alone,
through the same discovery and loader, so `agent_memory.rs` keeps only
that call; the filename table is pebble's now.
A retained thread's export comes from `export_for_reuse`, which closes
the session and hands back an export whose cursor is already past the
close, in place of export, shutdown, and a cursor advance by hand. Ask
Fabro resumes a stored record with `resume_after`, the rule it applied
under the older name.

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.

Steps 1 and 2 of .ai/plans/pebble-absorbs-embedder-concerns.md, pinning
pebble 1a5abe4.
Files touched come from `PromptReport`: pebble computes them from every
successful write, edit, and patch across the prompt, subagents included,
so the event-fed `FileTracking` and the tracking half of
`WorkflowEventSink` go. The stage unions the reports of its prompts.
Route failover is pebble's. The stage resolves its plan from the catalog
as before and hands pebble the remaining routes through
`fallback_routes`, each with its controls and the stage's output limit.
Pebble keeps the conversation, moves it to the next route, requeues
pending steering, and continues the prompt; the stage's plan follows the
route the report says the prompt ended on, re-activates the session
there, and mirrors pebble's `RouteFailover` as the run's `agent.failover`
event with the same payload as before. `prompt_with_failover`,
`resume_agent_on_route`, and the route bookkeeping in `LiveAgent` go.
One-shot prompt stages still walk the plan themselves.
`agent.route.failover` and `agent.tool.rounds.exhausted` join the derived
event names; both variants were falling back to `agent.event`.

Step 0 of .ai/plans/pebble-absorbs-embedder-concerns.md. Pebble's
fabro-exec-sink-max-turns branch is merged into its main (pebble 4db661c,
on the embedder-concerns branch until it lands), so fabro and petri pin
one line. Both prompt budgets survive the merge because they count
different things.
- Agent hooks use `with_max_tool_rounds`, which is what the
`max_tool_rounds` setting names and what petri does: `max_tool_rounds`
model turns may run, and the hook proceeds on a turn that still asks for
tools, so pebble gets `max_tool_rounds - 1` rounds and `ToolRoundsExhausted`
fails open. Zero rounds proceeds without an agent, as the old loop did.
Agent stages set no turn budget; the stage timeout and stall watchdog
bound them.
- Prompt stages load project memory through pebble's `ProjectMemory`, the
loader agent stages already run over `with_memory_files`, instead of a
hand-rolled copy of its budget, deduplication, and truncation.
- `fabro_sandbox::SecretRedactor` puts fabro's secret scanner on pebble's
text seams (process output tails, failed tool messages) for agent
stages, Ask Fabro, hook evaluators, and `fabro exec`. The final redaction
pass over every stored `RunEvent` stays; this does not replace it.
- Agent stages state their compaction policy explicitly: the 80 percent
threshold and six preserved turns fabro's own agent loop applied.

Replace fabro's hand-written agent loop with pebble's `CodingAgent` and
delete the `fabro-agent` crate.
Workflow: `PebbleBackend` builds one agent per stage over `RunSandbox`,
binds the stage's hooks as tool middleware, the interviewer as the
human-input provider, and a durable `EventSink` that writes every agent
event through the run event log before the agent goes on. Full-fidelity
threads continue across stages through `export`/`resume_from_export`.
Model failover takes the session record after the failed prompt and
continues it on the next route with `ResumeMode::UseModel`, so no tool
effect repeats. The steering hub targets pebble's control handle, with
a steering lease holding completion open while a human is paired.
Events: `EventBody::Agent` carries pebble's `CodingAgentEvent` envelope;
the per-variant bodies, the transcript projection, and the fabro-only
context-window, tool-summary, and skill types are gone in favor of
pebble's. The OpenAPI schemas, generated Rust and TypeScript clients,
and web readers follow.
Ask Fabro: the session runs a `CodingAgent` under a read-only permission
policy and a system prompt transform. Its conversation lives in a new
`run_session_records` table and resumes on the recorded model with the
event cursor advanced past the run log.
`fabro exec` builds the same agent over a local sandbox with pebble's
permission middleware and an interactive approval service.
The catalog fills in `metadata.agent.profile` for operator providers
that declare none, so pebble's lookup is the one resolution path.

The plugin supervisor now answers to the configured kind, which fabro's

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.

The driver branch gained equality on statuses and events, a git failure
that says when a command timed out, and lost the misleading
GitAttempt::succeeded; nothing in fabro used the method.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The agent launched a sandbox MCP server with its own setsid wrapper and
PID handling, polled ss for the port in a shell loop, and read a fixed log
file for failures; the server listed a sandbox's services with its own ss
and procfs scripts and parsers, and told the API which one it had used.
The driver's services facet now does both: the agent spawns the server as
a service, waits for the port, reads the service's logs on failure, and
stops it on cancellation; the server lists the driver's listening ports,
grouped by port with the process names the sandbox can give. The
discovery source leaves the API and the web panel's iproute2 tip goes
with it.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Fabro named Daytona snapshots by an HMAC of the image or Dockerfile, the
resources, and the API key, ensured them through the driver's snapshot
service before every create, and threaded that work through a create
plan so the sandbox could learn the snapshot it came from. The driver's
Daytona provider now does this inside create: an image or Dockerfile
spec is built once into a snapshot named by its inputs under the API key
and reused for the same inputs, with the build reported through the
create's events. Fabro's overlay only fixes the working directory,
names the run, sets the timers, and falls back to Daytona's default
snapshot; the sandbox reads the snapshot it came from off the driver's
status after the create. The snapshot identity module, the ensure step,
the create plan, and fabro-sandbox's hashing dependencies go. Snapshot
names change from fabro-<uuid> to the driver's sandbox-driver-<hex>, so
existing snapshots are rebuilt once.

Fabro projected the driver's status into its own state enum, resource,
network, and timestamp types for the run sandbox and inventory endpoints,
losing the provider's state string, the network policy, the sandbox kind,
and the driver's own vocabulary along the way. The API now carries the
driver's SandboxStatus itself: SandboxDetails is fabro's run record beside
the status, SandboxInfo is the provider beside the status, and the
OpenAPI schema describes the driver's types (state, resources in the
units the driver reports, the network policy, the sandbox kind, workspace
ownership) which fabro-api reuses through with_replacement with round
trip tests proving identity and JSON parity. The projection types and
their conversion go; the web sandbox page and summary panel read the
status directly, and the TypeScript client is regenerated.

Fabro assembled its own hardened git command lines (maintenance, hooks,
fsmonitor, path quoting, signing, the file transport, external diff
drivers) in three crates and parsed raw diff, numstat, cat-file, and log
output itself. The driver's git facet now carries fetch, rev-parse,
ancestry, diff entries, numstat, patch, log, blob sizes and contents,
config, untracked files, and stage-all, hardened by default and typed, so
the checkpoint commit, the run diffs, the Run Files listing and blob
reads, the commit log, the fork fetch, the agent's changed-files
detection, and the git identity setup go through it. The parsers and the
command prefixes go; the per-run capability probe keeps its own plumbing
script. Checkpoint commits never run repository hooks now, so
skip_git_hooks and commit_timeout are accepted for compatibility only.

The driver's section-4-driver-items branch (lithoscomputer/sandbox-driver#20)
carries the provider-owned scopes, the supervisor as provider, Host attach

services port verbs, and RFC 3339 wire timestamps. This commit only moves
the pin and follows the two API changes that no longer compile: the status

supervisor is launched rather than constructed. The deletion rounds follow
one item per commit.

Add pebble-agent and pebble-coding-agent as git dependencies pinned to
the pebble branch that carries the live exec output sink and max_turns,
and align the shared crate versions with lithos-llm's lockfile.
RunSandbox implements pebble_coding_agent::environment::Environment
directly: rename_file over the driver's rename with a pre-created
destination parent, grep rendered as path:line:text, pebble's glob
grammar enforced before the driver sees a pattern, directory listings in
tree order, and exec over the streaming path with the output sink mapped
onto the driver's OutputSink. Pebble's EnvironmentContract runs against
the Host provider in the unit tests and against Docker in the live suite.

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.

Pull request #18 on the driver is merged as a merge commit, so the
commit fabro was pinned to is an ancestor of main. Follow main.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Fabro's run-branch setup and its pushes were the last git it assembled
by hand: two rev-parse calls, a checkout -B, and a push built as shell
and run through exec. Because those failures never passed through the
driver, fabro kept a second classifier that read git's stderr for the
same auth and not-found shapes the driver already classifies for a
clone.
Both now call the facet. Setup reads the current branch and head commit
from the driver's status and creates or moves the run branch at that
base; a push sends its refspec with what remains of the retry plan's
attempt budget as the push timeout. The retry plan, the credential
lease, and the drift repair stay as they were — they are fabro's
policy — but the decision they act on comes from the driver's failure
class, the same way the clone's does. The output-shaped classifiers and
the auth hint matchers are deleted; the message classifier remains for
the host-side repository probe and metadata push, which never run
inside a sandbox. A git failure's captured output now renders as the
attempt's output tail, as an exec failure's did.
The driver pin moves to lithoscomputer/sandbox-driver#18, which adds the
push refspec and timeout, the checkout start point, and the status head
this relies on.

fabro-types no longer re-exports the lithos catalog and request types
(ProviderId, ModelId, ModelHandle, Message, ContentPart, TokenCounts,
Cost, Speed, ReasoningEffort, ReasoningOutput, and the rest). Every
crate that uses them depends on lithos-llm and names them there, and
the fabro-api progenitor replacements point at the lithos paths.

lithos-llm now ships the built-in provider ids and constructors, so
fabro-types drops its provider_ids module and every caller uses

Delete fabro-llm's attachments, reasoning, and structured modules and

auth, cancel, and failover predicates directly on Error and ErrorData.
fabro-llm keeps only failure_signature_hint, which is Fabro's own loop

The second-wave driver work — the tag pin, classified git failures, the
stop ladder, snapshot ensure, owner scoping, and the testing crate — is
merged as pull requests #10 through #15, so fabro follows the merge
commit on main instead of the head of the open stack. The content is
the same; the commits were rebased, so every hash changed.
CI installs the driver's plugin executables at the rev it reads from
Cargo.toml, so this also moves the executables the plugin scenarios run.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
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.

The sandbox-driver stack fabro pins now carries five things fabro used
to do itself, so fabro stops doing them. A tag pin is a clone option,
so the exec-based init, fetch, and checkout path for tags is gone and
every pin goes through the driver's clone; the shell command builders
and the hermetic git proofs that only served that path go with it. The
driver classifies every git failure it produces, so the retry module
keeps only the decision (a rejected credential is retried while a fresh
App token may still be replicating; an unreachable remote is retried
whatever the credential; everything else is permanent) and its hint
tables are gone. The provider runs the TERM, grace, KILL ladder for the
timeout and for the caller's cancellation, so the exec wrapper sets the
grace on the spec, passes the cancellation token as the term stop, and
reads the driver's verdict instead of racing its own timer. Daytona's
snapshot is ensured by the driver, so the list, activate, create, and
poll sequence and its back-off loop are gone. Every provider is
connected through the driver's ownership scope, narrowed to the run when
one is known, so creates carry fabro's labels and attaches to anything
else are refused by the driver; the label module keeps only the label
names, and the inventory provider reads the scope's answers instead of
checking labels itself.
The pin moves to the stack head with the driver's fix for a command
that honours the TERM inside the grace, which fabro's own tests caught
as a timeout reported as a cancellation. The Docker checkpoint
integration tests now create their container through the driver, since
the driver attaches only to containers it created; they were reaching
for a hand-run container since the Docker cutover.

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.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
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.

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.

Add lithos-llm as a pinned git dependency and replace the in-repo
`test/twin/openai` crate with the published `twins` revision that
lithos-llm verifies its codecs against. Move the Fabro policy overlay
(`fabro-policy.toml`) into fabro-llm so Fabro owns its own catalog
policy layer.
Drop the twin-openai nextest overrides and CI package filter now that the
crate is no longer a workspace member.

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.

fabro_sandbox::driver::connect_provider turns one
[server.sandbox.providers.<kind>] entry into an Arc<dyn SandboxProvider>
from the sandbox-driver crates. Bundled kinds link the driver's Host,
Docker, and Daytona providers in-process; Daytona receives its API key
and endpoint explicitly through connect_explicit with a
fabro-sandbox/<version> user agent, never from the process environment.
Any other kind launches the configured plugin executable through a
PluginSupervisor and returns a wrapper that replaces a crashed plugin
for new work only, never replaying a failed call. Disabled entries are
refused at the construction point.
The Host and Docker providers also ship as fabro-sandbox-host and
fabro-sandbox-docker plugin executables so CI can drive the bundled
providers over stdio and a deployment can move one out of process by
configuration alone. An integration test registers the Host executable
under the non-bundled kind `host`, creates a sandbox and runs a command
over the wire, then attaches to it by persisted id from a fresh plugin
process, and checks that a plugin declaring a different kind is refused.

Fabro pins the sandbox-driver workspace the same way it pins the
Daytona SDK: every crate at one commit on main. The bundled Host,
Docker, and Daytona provider libraries link in-process, and the
protocol crate reaches third-party providers over stdio. Nothing uses
the crates yet; the following commits move fabro onto them one layer
at a time.
The driver pins tracing-subscriber exactly, so the lockfile settles on
that version for the whole workspace.

Both fabro and sandbox-driver now pin the same daytona-sdk-rust commit
on main. The newer SDK adds region and sandbox class fields to snapshot
creation; fabro leaves both unset and keeps its current behavior.
