The pin moves from the head of the section-4-driver-items branch (a92c0db6,
since merged as #20) to main, which adds #21: the protocol crate's
PluginSupervisor gains numbered generations, a health probe before a
generation serves, and a refusal of a replacement that reports another
resource namespace. Petri pins the same revision, so the two runners share
one sandbox-driver.
cargo build --workspace and cargo nextest run -p fabro-sandbox -p
fabro-workflow pass (1502 tests, 48 skipped).

The stack this branch grew from was rebase-merged, so main carries the same
content under new commits; every conflict resolves to this branch's side.

StageProjection.agent_control and the AgentControlState schema go with the
field; the agent's activity on AgentSessionProjection carries the fact.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The session_projection_parity module pinned fabro's stage fold to pebble's
SessionProjection while both existed; the stage view reads the fold now,
and the one usage rule has its own tests. StageProjection.agent_control
and AgentControlState go too: pebble's fold carries the interrupted and
steered facts as agent.activity, and the stage's state says whether the
stage still runs, which is what the reset on fabro's own stage events was
for. The run-detail banner reads activity plus state.

The demo agent stage's stored events now read as one pebble session: MCP
servers up and failed, skills, a subagent, a failover, a compaction, and a
written file, ending with ProcessingEnd. Demo mode serves the run state it
answered not_implemented to, with the agent stage carrying the coding
agent's fold of those events, so the stage sidebar renders them.

Pebble's CodingAgentEvent stream is the agent event contract: every event
except streaming deltas is stored verbatim under its derived name and
folded into StageProjection.agent with pebble's SessionProjection. The
events doc, the events strategy, and the v2 shape doc say so, list the
agent events fabro still emits for facts pebble cannot know, and tell
consumers to read the fold rather than fold the events again.

Pebble's stream is the agent event contract. The run's own agent.mcp.ready,
agent.mcp.failed, and agent.mcp.disconnected events, which mirrored pebble's
McpServer* events, are gone with their props, the sink arms that emitted
them, and their conversion and naming entries; pebble's stored
agent.mcp.server.* events are the only record and feed the stage's fold.
The sink no longer mirrors RouteFailover onto agent.failover either: an
agent stage's moves are pebble's agent.route.failover. The event is now
prompt.failover, emitted only by a one-shot prompt stage that walks its
fallback plan itself, and its props are trimmed to the two routes, the
attempt, and the error; nothing read the rest.

The stage insights sidebar reads every session fact from the coding
agent's fold: the root agent's todo list with subagent lists counted
apart, MCP status derived from disconnected, error, and tools, skills, and
new Files and Subagents sections, a failover badge naming the route the
session moved to and why it stopped, and a compactions row under the
context window. The run state refreshes on the agent's own events those
sections read.

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.

An agent stage that failed billed nothing: the backend returned a bare
error and the outcome built from it carried no usage. A terminal failure
now becomes the stage's failed outcome from the same fold that bills a
completed stage, with the tree's usage, the rows by model, the files it
wrote, and its active time; stage.failed carries billing and
billing_by_model and the store keeps both. Cancellation and retryable
failures still go up as the error.

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.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
One usage rule: a stage's usage is its session tree's, the root and every
subagent, live and at completion. The worker's event sink folds pebble's
SessionProjection over the events it records and the stage's billing and
files come from that fold at stage end, so the completed values are what
the run showed live. The store's live usage is the fold's tree usage, and
completion brings the catalog's price for the same tokens instead of
resetting them to the root's.
Fabro keeps catalog pricing: the root at its route, each descendant at its
own route where the catalog knows it and at the root's otherwise, a
provider-reported cost standing in where pebble has one. The rows travel
as billing_by_model on stage.completed and the stage projection, and the
billing rollup splits by_model by them.

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.

StageProjection.agent is pebble's fold of the stage's agent events, fed
every stored agent event before the fabro-only arms run. Every existing
field and arm stays for now. The parity tests prove each old field is
derivable from the embedded fold: the tree's usage, the route as the model,
the context window without fabro's stamped seq, the root's todo list, the
subagent rows, the skills, and the MCP servers under the disconnected,
error, ready rule.

Pebble's SessionProjection reads ProcessingEnd to complete a prompt and mark
the session idle, so a projection rebuilt from the run's log needs it: one
small event per prompt. The four pebble events the sink mirrored onto
fabro's own agent.failover and agent.mcp.* are now stored verbatim as well,
so the fold sees the route moves and the MCP outcomes; the mirrors stay
until every reader is on the projection.

One usage rule: a stage's usage is its session tree's, the root and every

SessionProjection over the events it records and the stage's billing and

Pebble now owns the trait an application hands its MCP support to reach a
port inside the environment. SandboxPortRoutes implements PortRoutes over
the run sandbox's preview-URL facet: a missing facet is Unsupported, a
driver failure is Failed with the driver error as its source. The mcp
feature no longer pins sandbox-driver, so fabro's sandbox-driver pin moves
on its own from here.
The new pebble rev also puts the summary call's usage and cost on
CompactionCompleted, which the CLI progress test literal names.

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.

The existing failover test asserts the backup continued the turn after
the primary committed a tool result. A new test exhausts a two-route
chain and checks that one agent.failover and one
agent.route.failover.stopped are stored on the work stage, the stop
after the error it reports, with the exhausted reason and the failing
route. The events catalog documents both.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Pebble publishes RouteFailoverStopped when a model error ends a prompt on
its route although fallback routes were configured: the error is
ineligible or the chain is exhausted. Fabro has no event of its own for
that case, so the pebble event is stored as it is under a derived name
next to agent.route.failover instead of the generic agent.event.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Pebble's RouteFailover event now describes the route that failed and how
the new route carried the prompt on. Record the continuation on fabro's
agent.failover event as an optional string (replay_prompt or
continue_turn); events written before it existed, and one-shot prompt
stages that walk the plan themselves, read as absent. The failed route's
usage, cost, and timing are not mirrored: the stage's totals already
include them through the prompt report, and no fabro run event carries
per-route usage yet.
