Delete fabro's own pricing: lithos-llm prices every response once
lithos-llm attaches a cost to every response at the client: the codec
keeps a provider-reported cost when the provider supplies one, and the
resolver fills the catalog's price for the route when it does not.
Pebble records that priced usage on every assistant turn and sums it,
so each AssistantMessage on the stream, and the store fold's live stage
usage, already carries the cost. Fabro's catalog re-pricing of the same
tokens was redundant, and is gone.

model_usage_from_llm, with_reported_cost, and every estimate_cost call
in fabro are deleted. The pebble handler's stage_usage groups pebble's
accounts by route and sums them with Usage::saturating_add, keeping the
cost and source pebble carried, so the terminal stage.completed usage is
the live fold's sum; it no longer fails when the catalog does not know a
provider. A one-shot prompt stage records the response's own usage and
cost as lithos-llm returned it. The per-model price cards in fabro-llm's
API module stay.

Tests: the pebble handler sums Catalog and Provider costs per row and
leaves a row's and the total's cost unknown once an answer was unpriced;
the store fold shows the same tokens and cost live and at completion,
and None at both for an unpriced answer; the agent integration test
compares the whole completed Usage with the live fold, cost included;
a one-shot prompt stage on a mocked OpenAI-compatible provider reports a
Catalog cost that lithos-llm's resolver attached, with no fabro pricing.

Document the Usage shape on run and stage events
run.completed, run.failed, stage.completed, stage.failed, and
agent.message carry lithos-llm's Usage; the API reference navigation
names the run usage endpoint.

Carry usage as lithos-llm's Usage and rename billing to usage
Re-pin lithos-llm to 55add4596b861a0623d00c3a54aa5c147c8d504b and
pebble to c91810fe51aece80359b9cd8efea971af0c46925, where token usage
and cost travel together as Usage { tokens: TokenCounts, cost:
Option<Cost> }. Fabro now carries that one type everywhere it used to
carry BilledTokenCounts, BilledModelUsage, UsdMicros, or a token count
beside a cost_usd_micros.

fabro-types: billing.rs is usage.rs with ModelRef, ModelUsage { model,
usage }, sum_usage, and usage_is_empty; billing_rollup.rs is
usage_rollup.rs with ProjectionUsageStage, ProjectionUsageByModel,
ProjectionUsageRollup, and usage_rollup_from_projection. Every usage
field is named usage: StageProjection.usage and usage_by_model,
Outcome<Option<ModelUsage>>, stage.completed and stage.failed usage and
usage_by_model, prompt.completed usage, run.completed and run.failed
usage (total_usd_micros is gone), Conclusion.usage, StageSummary.usage,
Run.usage. RunSize buckets by Cost.

fabro-workflow: model_usage_from_llm prices tokens from the catalog with
a Catalog cost source, with_reported_cost keeps a provider cost, and the
pebble handler's stage_usage groups pebble's accounts by model and sums
rows with Usage::saturating_add, so a total has a cost only when every
priced part was priced. The store fold's live usage is the agent's
usage plus its descendants'.

API: the OpenAPI spec deletes BilledTokenCounts, BilledModelUsage,
CompletionUsage, CompletionCost, TokenUsage, and RunBillingSummary,
adds TokenCounts, Cost, Usage, and ModelUsage, and renames every
billing schema, property, tag, path, and operation to usage. fabro-api
reuses lithos-llm's and fabro-types' types through with_replacement,
with a round-trip test per replacement.

Old stored runs get no migration: their pebble events in the old shape
read back with zero usage, and their rebuilt projections lose agent
usage.

Read the stage view from the agent's fold
StageProjection loses todos, subagents, skills, mcp_servers, and
context_window, the types behind them, their fold arms and helpers, and
their OpenAPI schemas: every one of those facts is pebble's fold in
StageProjection.agent now. The context-window endpoint reads the fold's
snapshot, whose event_seq is the agent's own sequence. The parity module
keeps its assertions on the surviving own fields, usage and model, and
checks that what the stage view reads from agent is the whole-session
fold's for the stage's events. The TypeScript client is regenerated and
its stale models removed.

Describe billing_by_model on the API and the Billing tab
StageProjection.billing_by_model and a BilledModelUsage schema that reuses
fabro's type; the TypeScript client regenerated; the Billing tab's token
tooltip says subagent tokens are included and priced at each subagent's
model; the stage.completed docs describe the rows and the one usage rule.

Describe StageProjection.agent on the API as pebble's own types
AgentSessionProjection and the schemas nested in it reuse pebble's types
through with_replacement; the AgentSession prefix marks the projection's
own types where fabro already has a schema of that name, and pebble's
event-level types keep their names. The round-trip test builds a
projection over a scripted stream, validates it against the spec with the
spec as the root document, checks every serialized key is declared, and
validates every enum variant this build knows. The TypeScript client is
regenerated.

Merge remote-tracking branch 'origin/main' into remove/run-metadata-branches
Resolve conflicts between the metadata-branch removal and the
sandbox-driver adoption on main:

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

Adopt pebble's MCP disconnect event and startup timing
Pebble reports an MCP server whose connection closed mid-session once,
as McpServerDisconnected, and carries startup_ms on McpServerReady and
McpServerFailed. The workflow event sink mirrors the disconnect onto a
new agent.mcp.disconnected run event shaped like agent.mcp.failed, and
passes startup_ms through on agent.mcp.ready and agent.mcp.failed. The
raw pebble event is not stored for these, so the timing would otherwise
be dropped at the boundary.

The stage projection's McpServerStatus gains a `disconnected` kind next
to `ready` and `failed`. The fold keeps the server's tool count and
sticky invoked flag and only moves the status. The OpenAPI
McpServerStatus oneOf gains McpServerStatusDisconnected, and the
fabro-api round-trip test covers its JSON shape. A new
session_projection_parity test folds the same MCP events through
pebble's SessionProjection and fabro's stage projection and compares
them, including pebble's `disconnected`.

ToolErrorKind::Timeout needs no fabro change: the kind is stored as
pebble serializes it and never matched.

Resolve one Git identity per run and inject it everywhere
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.

6f72d369bf Document that fabro_run_create does not apply user run defaults
Tool-created runs no longer layer the caller's ~/.fabro/settings.toml
[run] defaults or project and machine run settings; only the values in
the request are transmitted, matching fabro run. The PR body stated this
but the public MCP and child-run docs did not, so callers relying on an
auto_approve or model default would see runs pause for approval or use
the default model without explanation. Note the behavior in both pages
and point at the explicit spec fields to use instead.

b413b9b29c Inherit the parent branch, not its pinned commit, for child run targets
A child created without a target copied the parent's full Git target,
including the sha admitted for the parent. Clone-based providers never
fall back to branch HEAD, so a child created after the parent pushed new
commits was checked out at the parent's starting commit and never saw
the work it was meant to review or continue.

Inherit the repository and branch only, so the child resolves the
branch's current remote HEAD at admission; the parent's pinned commit and
tag stay on the parent. Callers that want a pinned child pass an explicit
target. Folder and none targets are unchanged.

20f3766e75 Derive standalone run-tool targets from the selected environment
Standalone fabro_run_create ignored the environment's provider and always
produced a Git target or failed, so a Local environment with no explicit
target was rejected by admission and a directory without Git metadata
hard-failed, while fabro run derived a folder target and a none target
for the same inputs.

Move the CLI's provider-aware derivation into fabro-manifest as a shared
helper with a typed error, and have the standalone adapter look up the
selected environment and call it. The helper also distinguishes a failed
remote query from an unpublished commit, so an offline ls-remote no
longer reports "push the commit and try again" when the branch is
already on the origin.

Merge origin/main into pebble-agent-loop
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.

Run agent stages, Ask Fabro, and fabro exec on pebble's CodingAgent
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.

Run the agent's MCP servers and the service listing through the driver's services facet
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.

Let the Daytona provider cache images as snapshots instead of fabro
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.

Put the driver's sandbox status on the API instead of a projection
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.

Run fabro's git plumbing through the driver's verbs
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.

Give the checkout its GitHub credentials through the driver's store
The GitHub App token reached the agent's git commands through the origin
URL: after the clone fabro ran `git remote set-url origin` with the
token embedded, then tracked which generation the URL carried, held an
embed lease across every push so a refresh could not rewrite the URL
mid-operation, re-embedded on the first auth-shaped push failure in
case the agent had rewritten origin, and redacted the URL out of every
log line and output tail. The token showed in `git remote -v` and
`.git/config`.

The driver now installs ambient credentials for a checkout: one
credential-store line beside the checkout and a `credential.helper`
entry pointing at it, with the remote URL untouched. Fabro's part is
`credentials.rs`: the token source, one mint for the clone, one resolve
per push operation, and the facet call. The clone carries the token per
call and installs it afterwards; the ACP refresh tick rewrites the store
instead of the URL; fabro's own pushes pin one resolved token for the
whole operation and pass it per call, so nothing is ever re-embedded and
a retry after replication lag presents the same token by construction.

Gone with the URL: `push_credentials.rs`, `redact.rs`, the lease and
drift repair in `git_push`, `RefreshOutcome`, and the `credential_action`
and `refresh_error` fields on push attempt events. Stored events that
carry those keys still read. A failed store install after the clone now
fails setup, where a failed `set-url` used to be logged and repaired by
the first push. The one remaining caller of the URL redactor, the
server's repository probe, uses `DisplaySafeUrl::redact_in`.

Merge origin/main into the sandbox-driver adoption
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.

the LlmError newtype and ErrorFacts trait. lithos-llm now provides all
of them: InlineLocalFiles under the local-files feature, ReasoningOutput

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

Store ErrorData directly in the agent and workflow error enums, boxed
where the variant would otherwise dominate the enum size. Repin
lithos-llm to a1e3fd3 for these additions.

Implement the lithos CredentialProvider trait directly
fabro-auth defined its own `CredentialSource` trait beside the lithos
`CredentialProvider`, with a parallel `ResolveError` and an adapter between
them, because lithos had no way to ask which providers a store can serve
right now. It does now: `credentials::readiness`, `ClientBuilder::build_ready`,
and `CredentialError::Unusable`.

- The vault, SQL vault, API-key, and extra-headers stores implement
  `CredentialProvider` directly. Material that is present but unusable (an
  expired token with no refresh, a wrong-typed vault entry, a header secret
  that did not resolve, a store read failure) is `CredentialError::Unusable`
  with the operator-facing reason; its `Display` replaces
  `auth_issue_message`. `is_configured` is the cheap presence check.
- `fabro_llm::build_client` calls `build_ready`; `FabroClient::auth_issues`
  carries `CredentialError`. `fabro_llm::configured_providers` replaces the
  per-store `configured_providers` method.
- `CredentialSource`, `ResolvedCredentials`, `lithos_credentials`,
  `ResolveError`, and `auth_issue_message` are deleted. Twenty files that
  held `Arc<dyn CredentialSource>` hold `Arc<dyn CredentialProvider>`.

Retire the fabro Sandbox trait for one concrete RunSandbox
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.

Document the catalog overlay without the metadata.fabro namespace
The `[llm]` reference now describes `enabled`, `api_key_url`,
`stands_in_for`, `small_default`, `probe`, `family`, and the cutoffs as
lithos fields, the coding harness under `metadata.agent`, and the secret
names lithos derives for operator-defined providers. Secret-bearing
headers go in `default_headers` as `{{ secrets.NAME }}` tokens. The
integration guides enable a provider with `enabled = true` on its table.

Resolve provider secrets through lithos conventional credentials
lithos-llm now owns which named secrets each provider reads and how they
shape into its auth scheme, including a derived `<PROVIDER>_API_KEY` for
operator-defined providers. Fabro's job shrinks to supplying the store:
`VaultCredentialSource` hands lithos a lookup that reads the process
environment, then the vault, under the same conventional names.

What Fabro still adds on top: the Codex OAuth credential in the vault,
refreshed and persisted when it expires; `{{ secrets.NAME }}` tokens in a
provider's `default_headers`, resolved against the vault and re-sent as
credential headers; and OpenAI organization and project headers from the
environment.

Deleted with the `metadata.fabro.credentials` list: `CredentialRef`,
`CredentialResolver`, `EnvCredentialSource` (now
`VaultCredentialSource::environment_only`), and the `env_var_names` /
`expected_vault_secret_name` helpers, replaced by `secret_names` and
`expected_secret_name` over the lithos table. `openai-codex` joins the
first-party provider id constants.

Map an environment onto one sandbox spec for every provider
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.

Name plugins by their configured kind and drop out-of-process bundled kinds
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.

Run plugin providers end to end and gate them in CI
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.

Route Daytona sandboxes through the sandbox driver
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.

Delete fabro-model and document the lithos catalog overlay
fabro-model's ids and billing rollup now live in fabro-types, and its
pricing, catalog, provider TOMLs, and legacy index are replaced by the
lithos built-in catalog plus the Fabro policy layer.

Regenerate the configuration reference for the `[llm]` overlay and
`metadata.fabro`, and rewrite the SDK, models, and integration docs for
the lithos provider and model shapes.

Expose lithos request and response shapes through the API, server, CLI, and web
The OpenAPI spec adopts the lithos request, response, content part,
tool, usage, and cost schemas. The completions endpoint returns the
lithos `Response` JSON verbatim and SSE carries lithos `StreamEvent`s
verbatim. The models and providers endpoints serve the fabro-types
catalog views, and the install and model-test flows probe providers
through fabro-llm.

The CLI builds its catalog from the operator overlay, drives `fabro exec`
through the server gateway adapter, and parses reasoning effort with the
shared controls. The web app reads content parts as lithos-tagged
objects. The TypeScript client is regenerated.

Route Docker sandboxes through the sandbox driver
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.

Open sandbox provider identity to plugin kinds
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.
