Step 4 of the legacy executor deletion, fourth commit: with no writer
and no reader left, the legacy event log goes.
- `fabro-types`: `run_event` (`EventBody`, `RunEvent` and every props
struct), `EventEnvelope` and the `RunEventDetail*` types are deleted.
What the projection and the API still use moves out of the event
vocabulary: `AgentEventProps`, `AgentSessionActivatedProps`,
`AgentToolsAvailableProps`, `StagePromptProps`, `SessionCapability`
and the coding event names to `agent_props`; `RunNoticeLevel` and
`RunNoticeCode` to `notice`; `InterviewOption` beside the question
types; `RunRunnableSource` beside the run status. `Checkpoint` is
what Fabro records for a Petri run: `timestamp`, `current_node`,
`git_commit_sha`; the conclusion's stage summaries derive from the
projection's stages instead of the checkpoint's node maps.
- `fabro-store`: the Slate bridge (`RunDatabase`, the Slate `Database`,
`keys`, `record`, `EventPayload`) and the reducer (`run_state`) are
deleted. `Database` is the blob table and the run summary store over
one pool; the blob store is SQLite only; the run summary store keeps
the `runs` row a projector writes and lists, and finds the pull
request creation candidates over `platform_records`; `build_summary`
and `projected_usage` live in `run_summary`. The SlateDB dependency
is gone. Test fixtures build the store from its two SQLite stores.
- `fabro-workflow`: the `event` module (the `Event` enum, its
conversion, sink, emitter, redaction, stored fields and names),
`runtime_store`, `StageScope` and the legacy seeding test helpers are
deleted; the tests that seeded legacy runs read platform records or
a projection instead.
- `fabro-sandbox` owns `GitRetryReason`.
- The server builds the store without an object store; the legacy
`POST /runs/{id}/events` tests go, an interrupt answers
`interrupt_unsupported` in the tests as it does in the handler, and
the tests that read a run back through the Slate handle read its
projection or its platform records. The projection folds a block
that lands while the run is paused as the pause's prior block, and a
pause or unpause clears the pending control it answers; a control
request's check-and-append holds a per-run lock so two concurrent
cancels record one request.
- The CLI's final output is the response of the last stage that
produced one; the workflow tests read completed nodes from the
succeeded stages.
- The spec's `RunCheckpoint` carries the three fields the type keeps.
Still failing until the next commits: the CLI tests that seed runs
through `POST /runs/{id}/events` or wait for legacy event names, and
the two Ask Fabro resume tests (the sandbox instance gap).

Petri judges a workflow at admission, so Fabro's lint rules go:
`fabro-validate` (its 35 rules and the `LintRule` trait) is deleted, and
with it `fabro-acp` (only a rule and two legacy executor tests used it),
the model-resolution transform, the legacy `create`, `compile_create_run`
and `materialize_create_run` stages, and `fabro-graphviz`'s `condition`
and `fidelity` modules. `Diagnostic`, `RelatedDiagnostic` and `Severity`
move to `fabro_types::diagnostic`, the one shape every diagnostic takes.
Validation is now the same question the create handler asks. A new
server module, `petri_check`, builds Petri's check request from a
workflow bundle and the run's settings (every workflow of the bundle at
its bundle-relative path, the inputs, the run variables, the launch),
runs the check, and maps the diagnostics; Fabro adds one rule of its
own, `fabro.model.no_ready_provider`, refusing a model node when no
provider is ready. Admission, the validate and preflight endpoints and
the offline `fabro validate` all go through it:
- `validate_prepared_manifest` runs Fabro's structural pass (parse and
transform, whose diagnostics stay) and then Petri's check, on the
blocking pool from the handlers;
- the offline `validate_manifest` checks with no model client and with
an unbound input as a warning (`CheckRequest.unbound_is_warning`), so
a workflow validates before its inputs exist; a collected workflow
before upload checks with unbound inputs as errors, as before;
- preflight resolves each LLM node's selector against the ready
providers and the catalog for its probe, as the deleted transform did,
and no longer probes a model Petri refused;
- the graph render endpoint needs only the structural pass;
- a run manifest now carries its `[run.goal] file`, which Petri reads
from the bundle as it does for a version.
The transforms keep the authored model selector (`sonnet` stays
`sonnet`): Petri pins the catalog model in the admitted graph, not in
the graph Fabro displays or in the settings snapshot. Tests assert that,
and the CLI's validate, preflight and graph snapshots carry Petri's
diagnostics (`attractor.no_start`, `attractor.undeclared_node`,
`attractor.bad_on_failure`, ...) in place of the lint rules' text.
Known gaps, Petri's side: a `workflow.toml` whose `[run.environment]`
names an environment the server catalog defines but the file does not
is refused (`unsupported.workflow_toml.run.environment`), as admission
already refused it; an unbound input inside an included template
partial is a render error rather than the unbound-input warning.

`fabro-mcp` held two things after the legacy executor went: the mapping
from Fabro's MCP server settings to the servers pebble starts, which
only `fabro exec` still uses, and a stdio MCP client the tests of
Fabro's own MCP server speak through. The mapping is now
`fabro-cli`'s `mcp_servers` module and the client its test support's
`McpStdioTestClient`; the crate is deleted. Its `config` module was a
re-export of `fabro_types::settings::run`, which callers import directly.

`fabro-hooks` ran the legacy executor's hooks; Petri's Attractor steps
run Fabro's hooks now, so nothing in the workspace uses the crate. The
engine freeze (the CI workflow, the two scripts, and the AGENTS.md and
fabro-petri README sections) guarded the engine half of `fabro-workflow`,
which the previous commit deleted.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Every run executes on Petri, so the in-process legacy executor goes:
`fabro-core` and, in `fabro-workflow`, the handlers, lifecycle, pipeline
execution, routing, retry, conditions, node handlers, steering, agent
memory, artifacts, checkpoints, command log, and the `start`, `resume`,
`retry`, `fork`, `rewind` and `timeline` operations. The two are deleted
together because the engine half of `fabro-workflow` was the only user of
`fabro-core` and `fabro-core` the only runtime of that half; neither
compiles without the other.
Kept in `fabro-workflow`, narrowed: the parse/transform/validate/persist
pipeline and `create`, `archive`, `validate` (workflow definitions still
come from DOT and settings); the run tools (`run_tools`, moved from
`handler/llm/fabro_tools.rs`) for Ask Fabro, `fabro exec` and Petri's
host tools; the pull request pipeline (`pull_request`, moved from
`pipeline/`, for the step 0 port); Run Files' diff helpers in
`sandbox_git`; `git_identity`, `usage_rollup`, `run_status`,
`run_materialization`, `web_search` and `workflow_bundle`.
Server: `RegistryFactoryOverride` becomes `execute_in_process`;
`RunAnswerTransport::InProcess` carries only the interviewer; the
interrupt endpoint answers 501 `interrupt_unsupported` and every pair
endpoint 501 `pair_unsupported` (status lists none); rewind, fork, retry
and timeline handlers and routes are removed; the command log is served
from the stage output blob; usage rollups accumulate from the settled
projection after an in-process run as after a worker exit.
Ported while here:
- `materialize_admitted_run` materializes the goal and drops a disabled
pull request block, as the legacy materializer did.
- A run whose admitted graph has an agent or prompt node is refused at
create when no LLM provider is ready (`fabro.model.no_ready_provider`);
a workflow of commands and gates needs no model and is admitted.
- The projection's question type falls back on the options, as the
interview adapter does, so a gate with edge-label options answers as
multiple choice.
Tests: the server scenarios (lifecycle, run completion, SSE, helpers)
run in process on Petri and assert Petri's stage labels and stream
names; the reconcile tests assert Petri's relaunch semantics; legacy
unit tests of the deleted executor are removed; three server unit tests
the removal took with it are restored; the pair fixtures go with the
pair feature. Petri test fixtures no longer name `[workflow] engine`.
Still red after this commit, all legacy consumers the next steps
delete or port: fabro-store's Slate/reducer fixtures and fabro-types
legacy JSON tests (step 4); server unit tests over legacy run events
(retry endpoints, list_run_events, artifacts, per-event pause/unpause,
run history activation, legacy sandbox fixtures) (steps 3-4); CLI tests
that parse legacy event envelopes, the legacy `events`/`attach`/`diff`/
`dump`/`inspect` snapshots, `run rewind`/`run fork`, the ACP and
git-identity workflow tests, and the runner tests that drive the legacy
worker by hand (steps 3-4); the web app's Petri fixtures still carry
`engine` (regenerate with `FABRO_CAPTURE_PETRI_FIXTURES` in step 4).

Petri's `scope_acquired` hook point and `SandboxOptions::lost_sandbox`,
which the sandbox checkpoints and their recovery build on.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Plan item F3.4. `fabro_petri::host_tools` adapts Petri's `HostTools`
capability to `register_fabro_run_tools`: every native agent session of a
run gets the tools the legacy worker registers, bound to the worker's
client and the run id, so a child run a stage creates is parented to the
Petri run. The tools run under the run's tool hooks, are recorded under
the stage, and reach sub-agents through Pebble's inheritance.
`RuntimeSpec::run_tools` installs the capability; the worker sets it when
the run's settings enable `[run.agent] fabro_tools` and the worker token
carries `agent:run_tools`, the legacy worker's gate. The server's
in-process test path runs without them, like the legacy one.
The identity the tools need is the run id alone; no run tool records a
stage on an effect, so nothing derives Fabro's `node@visit` label. A
context for another run gets no tools.

In-process tests over the memory store: every finish is committed on the
run branch with its identity trailers and recorded with its commit, the
run-end hooks reach Petri's local service through Fabro's wrapper, a
stage that fails on its own terms is committed and its failure route runs
on the committed files, a failed checkpoint records `checkpoint_failed`
with no route taken and a restart reports the run failed, and a
`[[run.hooks]]` hook blocks an agent's tool call through the forwarded
service, with the model told why.
Real-binary scenarios crash the server and its worker with SIGKILL: after
a durable finish the stage's commit is not repeated and the interrupted
stage reruns on its snapshot; a crash held before the commit reruns the
stage once; a crash held after the commit but before its record
reconciles the record from the snapshot repository; a deleted workspace
is restored; a failure route sees the same committed files after a
crash; a failed checkpoint fails the run and a restart leaves it failed.
Recovery selects the executions `inspect_run` reports incomplete, and a
run whose coordinator log is still empty is left to the worker's resume.
The worker's platform record endpoints get an API test and the generated
TypeScript client.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Fabro's hooks on a Petri run wrap the hooks the runtime installed for
`[[run.hooks]]` and forward every point. In `prepare_result`, before the
finish is recorded, they commit the stage's files on the run branch of
its host workspace with Fabro's author identity and the run, execution,
firing and attempt as trailers, and publish the commit to a snapshot
repository beside the run's workspaces under a ref per checkpoint. A
stage that failed on its own terms is committed like a successful one; a
commit that fails is fatal: the outcome becomes a `checkpoint_failed`
failure, the run is cancelled through the coordinator handle, and the
transition refuses the firing's routes. In `transition` they write the
platform checkpoint record, keyed on the Petri position and the
checkpoint's operation identity, and a failed write is a recorded
problem.
On restart the server runs the recovery protocol before it relaunches a
worker: a run with a failed checkpoint is reported failed; otherwise
every live execution's last durable finish names the snapshot its
workspace is verified against, reset to, or restored from, with a lost
record reconciled from the snapshot repository, and a finish with no
snapshot fails the run rather than resume it on stale files.
The worker reaches the platform records over two new worker-scoped
endpoints; the server reaches the table directly. A test gate directory
lets the CLI scenarios hold a checkpoint at a named point.

The projection folds Petri's public events (replay_since over the run's
stored records) and Fabro's platform records into the RunProjection the
API serves, row by row as VIEWS.md maps them. The stage key is the
execution and firing; the StageId label is node@visit, made unique with
the execution when two child invocations would share one. A stage's
first_event_seq is the milliseconds from the run's creation to its
visit.started, so the view built live equals the view rebuilt from the
records whatever order two logs' records were committed in.
The projector is the view pass and its wake-up. Records first: an append
returns before any view work; a pass reads what is committed, folds the
items past the committed positions, and writes the projection document,
the ordered stream (one stream_seq per Petri event or platform record,
with the item's own identity beside it) and the narrowed runs row in one
later transaction. Signals coalesce per run, a lost signal costs only
latency, the startup pass folds every run the view trails, and a pass
that races a platform record leaves the view alone and runs again. A
torn tail holds the view where it stands and reports the run incomplete
with the replay's error; inspect_run decides completeness once the run
recorded its finish.
The tests build the view live for the hello bundle, a command workflow
and a two-branch parallel workflow and compare it with the rebuild; drop
every wake-up and catch up by a signal and by the startup pass; crash
between the record commit and the view transaction and apply only the
suffix; restart the projector over child executions; and hold at a torn
tail.

A Petri run in the worker, and in the server under its test override, now
gets Fabro's platform adapters instead of the standalone defaults:
- `fabro_petri::interview`: Petri's `Interviewer` over the questions API
and the worker's control channel. A human gate's question is posted as
the `interview.started` event a legacy stage emits, keyed by an id
derived from Petri's identity (node, execution, firing, occurrence,
ask), so the API, the web app and Slack list it; the answer posted to
the questions endpoint reaches the control interviewer the adapter waits
on and is mapped onto Petri's answer. An expiry the gate reports is
completed as `interview.timeout`, a cancel as `interview.interrupted`,
and an auto-approved run answers itself. The hook points the read side
takes over are marked.
- `fabro_petri::secrets`: Petri's `SecretProvider` over the vault's token
entries, so `{{ secrets.NAME }}` resolves at spawn and is masked in every
record; a sensitive answer registers as a dynamic secret.
- `fabro_petri::blobs`: Petri's `OutputStore` over Fabro's `blobs` table,
through the server's blob store or the worker's client.
- The Fabro home the server resolved travels to the worker as
`--fabro-home`, so the skills step reads it whatever the worker's
environment says.
`engine::RunRequest` takes the interviewer, its observers, the secret
provider and the blob table from the caller; `interviewer::Unattended` is
gone.

Petri's `fabro-integration-p1` branch at 83345a8 adds
`Runtime::check_source`, the in-memory check entry point over a
`frontend::FileSource`, and makes `[workflow] engine` a known
`workflow.toml` key in its Fabro frontend, refusing any other unknown
`[workflow]` key with `unsupported.workflow_toml.key`.
Every `petri_*` entry moves from a0d2ceb to 83345a8. The lockfile changes
only the source line of the fifteen Petri packages; no other crate moves.

When `fabro run __run-worker` finds its run's stored spec names Petri, the
new `petri_worker` module executes it through `fabro_petri::engine` over
`HttpRunStore`, leased for a launch id the worker mints and logs at start.
`--mode start` loads the admitted graphs through the client's blob read;
`--mode resume` continues the run from its records. The worker's existing
services carry over: the control channel's cancel and SIGTERM/SIGINT cancel
Petri's root invocation politely, a lost control channel cancels the run
and is reported once it settles, and pause, unpause and steer are received
and ignored with a warning until their adapters land. The model client
comes from the worker's catalog and vault snapshot for the providers whose
credentials resolve, and the lifecycle events (`run.starting`,
`run.running`, then `run.completed` or `run.failed`) go through the client
as the legacy worker's do.
Scenario tests against the real binary: a command-only Petri run executes
in the worker a foreground server launched, its records reach
`petri_records` over the HTTP store and its lease ends with the worker; and
a run whose server and worker are both killed mid-stage resumes in a new
worker after the server restarts, with one `run.completed`.

`check` materializes a workflow version's bundle into a temporary directory
(`Runtime::check` reads files from disk), lowers it with the run's inputs
and launch, and returns the admitted graphs or Petri's diagnostics in a
shape the server maps onto Fabro's. `admission` keeps the admitted graphs
in the blob store, named on the run spec and verified by digest on load.
`runtime` assembles the same Petri runtime at create and at execution: the
Fabro frontend with the server's settings layer, the Attractor step kinds,
the model client as the PebbleClient capability so admission pins every
model. `engine` runs the admitted graph in the server process over
SqliteRunStore under the Fabro run id, with the standalone defaults, an
interviewer that fails any question, and cancel on a token, and derives the
outcome from inspect_run over the run's record.

The server answers the `/api/v1/runs/{id}/petri/*` endpoints from one
`SqliteRunStore` over its pool. `PetriRuns` in `AppState` keeps the
writer handle each worker opened, keyed by the run and the worker's
owner id, so the lease semantics stay the store's: the handle drops on
the worker's `release`, and every handle of a run drops when the server
observes the run's worker exit, in the subprocess wait path. Never by
timeout. A write from an owner with no held handle reopens only when
the lease row still names that owner, so a server restart or a lost
open reply recovers, and an owner the lease moved away from gets
`petri_stale_owner`.
Every endpoint is worker-scoped through the existing worker auth; a
new `RequireWorkerRunSegment` extractor covers the two-segment routes.
Store errors answer with a machine-readable code, the leased owner and
the conflict position under `meta`, and a backend failure's cause goes
to the server log rather than the worker.
A test drives a held worker through the scheduler, opens the run over
the API with its token, ends the worker, and sees the lease end.

`SqliteRunStore` implements Petri's `RunStore` and `RunLogs` on the pool
Fabro's other stores share. A run's existence and writer lease live in
`petri_runs`; every record of every log lives in `petri_records`, keyed by
(run, log, seq) with the record stored as JSON and read back unchanged;
blobs share the `blobs` table with `BlobStore`. The lease is taken
idempotently per owner, ends when the last handle drops or when an
operator releases it, and never by timeout; every write checks it inside
its own transaction. An append is one `BEGIN IMMEDIATE` transaction per
batch: a repeated record is accepted, a different record at a taken seq or
a seq past the head is a conflict that stores nothing.
Petri's store conformance suite passes against it, with the operator
release, lease exclusivity, a crash between appends, and blob
interoperation checked beside it.

Fabro runs its workflows on Petri. The six Petri packages and the testkit
are pinned by revision in the workspace manifest under `petri_*` keys, and
`fabro-petri` is the one crate that depends on them. The crate's tests run
the `hello` bundle in memory on the stub registry and a command-only
workflow on the host sandbox; both skip without the sandbox-driver host
plugin, and the sandbox-plugins CI job requires it.

Pebble main a39f43e26effdf99635eaf343f095c17157c9c93 (pebble #22) carries
an assistant turn's usage as Usage in the session record and moves the
record format to version 5. CodingRuntime::from_record refuses a record
in another format with UnsupportedRecord { version, supported } before
it reads the route. Fabro persists those records in SQLite for Ask Fabro
resume, and old runs get no migration, so a record written by an older
build is read back as stored and refused on the next turn.
Two tests pin that down. The store reads pebble's own version 4 fixture
back through get without a parse error and reports it unsupported. A
resumed Ask Fabro session whose stored record declares the previous
format fails its next turn with the agent_error code and the message
"session record format version 4 is not supported (this build requires
5)", runs no turn, and leaves the stored record in place.

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.

Moves the eight sandbox-driver crates from ddb32e1 to 64c14b8, which
brings sandbox-driver PR #22 (Daytona output resync): the Daytona
plugin's encoded-exec decoder no longer fails a command on a torn frame.
It discards through the next newline, counts the loss in the new
`sandbox_driver::OutputLoss { dropped_frames, dropped_bytes }`, and
carries it as `ExecStreamingResult::output_loss` (serde default) across
the plugin wire. A loss also sets `truncated` on both captures, so
`into_complete()` refuses while `run_streaming` completes. PR #21
(supervisor generations) was already on main under the previous pin.
Nothing in fabro needed a source change for the bump. The lockfile
changes only the eight driver source lines; the unrelated windows-sys,
windows-core, and errno flips `cargo update` proposed are not taken, and
`cargo metadata --locked` accepts the result.

AgentSessionProjection and the schemas nested in it reuse pebble's types

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

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.

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.

Pebble's mcp-embedder-events branch gained a commit that waits for an

Pebble's McpServerReady and McpServerFailed events now carry startup_ms.
The workflow event sink destructured both variants by name, so it stops
listing every field. The pin is temporary: it moves to pebble main once
lithoscomputer/pebble merges the branch.

Deduplicate shared-filesystem capability checks and simplify workflow-source dispatch and types. Move Git observation and local package collection onto spawn_blocking, and flush inline workflow files before collection.
Simplify validated source and input types, derive inline size-limit messages from shared constants, add target schema-parity coverage, and remove dead producer pass-through parameters.
Pebble main `222d17f` merges the sandbox-driver re-pin fabro was
pointing at by branch commit. Same tree as `9ec23d0`, so this is a
lockfile-only change.

The packager logged the full packaging error chain at WARN. That chain
embeds caller-supplied workflow and prompt source: the graph parser's
diagnostic includes the unparsed remainder and the TOML parser prints
the offending line. The logging strategy prohibits user file contents
in tracing events at every level, and this adapter runs inside
`fabro mcp` and run workers at the default filter.
Log the collector error's own path-only message at DEBUG, since a
malformed request is an expected input error, together with the
entrypoint and file count. Wrap the blocking-task join error with
`context` instead of interpolating it. A test installs a TRACE-level
subscriber around the blocking path and checks that the fixture's
source marker, which the full chain does contain, never reaches the
log.

ServerWorkflowVersionPackager was a pure adapter over
fabro_manifest::collect_supplied_workflow_versions that touched no
server state, yet it lived in fabro-server and was imported from there
by the standalone MCP server and the CLI run worker. fabro-manifest can
depend on fabro-tool without a cycle, so the adapter now lives beside
the collector as SuppliedWorkflowVersionPackager and fabro-server no
longer exports a non-server module for it.
The adapter also cloned every version's file map out of a closure it
already owned. CollectedWorkflowClosure::into_versions hands the
versions over by value inside the blocking task instead.

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.
