Replace 16 inline copies of the `[cli.target] type = "http"` settings TOML across CLI integration tests with a single `set_http_target(&base_url)` method on `TestContext`. Removes a brittle format string that was maintained in ten files but only meaningfully asserted-against in one.

Drop --allow-no-checkpoints and the paired ManifestArgs in_place /
allow_no_checkpoints fields. The CLI now translates --in-place into a
single ManifestArgs.worktree_mode = "never" signal that flows through
the existing args→layer pipeline as run.sandbox.local.worktree_mode =
Never. The server computes prepared.in_place from the resolved settings
once, replacing the trio of bail!s and the sandbox-default fixup.
Skip worktree checkpoint setup when a local sandbox is not backed by a git repository, and keep the API contract aligned with RunSpec serialization for omitted labels.
Move server-only settings reads out of user-facing CLI commands into a
dedicated local_server module, the install/uninstall exceptions, and the
worker subcommand. Adds bin/dev/check-boundary.sh to prevent regressions.

Implements the plan at
docs/plans/2026-04-20-003-refactor-unify-run-vocabulary-metadata-plan.md.
- Rename RunRecord to RunSpec and RunProjection.run to .spec everywhere
in Rust source, tests, helpers, test names, and error messages.
- Introduce SerializableProjection wrapper that trims bulky node text
fields (prompt, response, diff, stdout, stderr) for run.json snapshots.
- Collapse metadata-branch and CLI export to one RunDump::from_projection
builder emitting run.json + graph.fabro + stages/{stage_id}/... and
drop legacy top-level start/status/checkpoint/sandbox/retro/conclusion
split files.
- Replace MetadataStore::write_checkpoint with write_snapshot returning
the commit SHA; add read_run_projection/read_run_spec; demote
read_checkpoint/read_start_record to projection-field extractors.
- Switch fork, rewind, rebuild_meta, CLI rewind recovery, and retro
upload to read the unified projection layout.
- Add additive query methods on RunSpec and RunProjection.
Serde-level `alias = "spec"` shim dropped; `rename = "run"` retained to
keep the server API wire format stable per the plan's scope boundary.

Phase 2/3 of the std::fs lint initiative (Phase 1 refactors landed in
commit 9d1c0d98c).
clippy.toml additions (appended to disallowed-methods):
std::fs::read, read_to_string, write, read_dir, copy, canonicalize
std::fs::File::open, File::create, File::create_new
std::fs::OpenOptions::open
File::options was deliberately excluded — it returns an OpenOptions
builder with no syscall. OpenOptions::open is where the block happens.
Non-blocking std::fs items (metadata, exists, create_dir_all, remove_*,
rename, and all std::fs types) remain legal.
Annotation policy (per updated plan):
- Mixed async/sync production source: function- or statement-scoped
#[expect(...)] so future accidental Tokio-path regressions in the
same file still fire.
- Fully-sync production source, test modules, integration tests,
build.rs: file-level #![expect(...)].
- Every #[expect] has a specific reason identifying the sync context.
Annotations added in ~90 files across the workspace. Notable narrow
placements: fabro-server server.rs current_server_target,
build_disk_usage_response, create_test_app_state_with_session_key;
fabro-server install.rs read_to_string rollback snapshot;
fabro-sandbox local.rs list_recursive; fabro-agent cli.rs FOLLOW-UP on
the JSON-stdout writer; fabro-llm providers/common.rs FOLLOW-UP for
load_file_as_base64 (7 translator call sites; revisit if file:// URL
usage grows).
build.rs blanket allows: fabro-api/build.rs, fabro-util/build.rs.
Pre-existing unrelated nightly-clippy warnings fixed under scope:
fabro-sandbox sandbox_spec.rs (unused_imports, unused_async),
reconnect.rs (unused_variables, unused_async).
Verified: cargo +nightly-2026-04-14 clippy --workspace --all-targets
-- -D warnings passes; fmt clean; 4129/4131 tests pass (two known
flakes under parallel nextest load, both pass individually and are
unrelated to this change).

- Add [GRAPH_PATH] filter to run_output_filters so dry_run_simple
snapshot is path-independent
- Double fabro-cli slow-timeout (3s → 6s) to prevent ps test timeouts
- Preserve cloud sandboxes; bump snapshot to fabro-v7 with 8 CPU / 16GB

Config discovery walks from the workflow file's parent directory, so
tests using fixtures at their repo path (test/simple.fabro) would find
the repo's .fabro/project.toml. This caused settings like preserve=true
to leak into tests and break sandbox cleanup event assertions.
Add TestContext::install_fixture() which copies fixtures into the test's
temp dir. Update all CLI run/attach/start tests to use it. Remove the
now-unused example_fixture() function.
Restore preserve=true in .fabro/project.toml — tests are now isolated.

- Remove EnvGuard and env-mutating test from fabro-auth (shared mutable state)
- Revert project.toml preserve=true that broke sandbox cleanup event tests
- Fix clippy: use is_some_and, scoped imports for StageStatus and render
- Update snapshot tests for new Run: ULID line and model_test output
- Fix preflight test assertion (name said "allows", asserted failure)
- Update cancel_queued_run test: cancelled runs now appear on board
- Add graph direction query param support to get_graph endpoint

Resolve CLI settings once from user config plus process-local overrides
and pass the resolved view through command dispatch and CommandContext.
This keeps config-driven cli.output, cli.updates, and cli.logging
behavior working while preserving commands that only reject explicit
--json overrides. It also removes the implicit auto-approve coupling
from JSON run output.
Conflicts resolved:
- install.rs: kept simplified auth (port 32276, no TLS, no username
in merge_server_settings), adapted to origin's input_source API by
removing username from ServerConfigSelection::Write
- serve.rs: kept ProviderCredentials import from origin, dropped
ClientAuth (removed with mTLS)
- server.rs: kept both imports (ServerAuthMethod + Provider)

Pass the shared storage dir into worker runs so vault-backed credentials
load during real workflow execution, including server-spawned workers.
Also finish the QA follow-ups around scripted install behavior, list
credential metadata in secret listings, and give the slow OpenAPI
conformance test a narrow nextest timeout override.
Propagate the local dev token through worker subprocesses, share the
same authenticated local-server helper across CLI integration tests,
and clean up the async token wait path so fmt, clippy, and full tests
pass again after the dev-token auth rollout.
Embed defaults.toml as a base settings layer and apply it when
materializing effective settings and resolving typed settings.
This also fixes partial CLI table merging so builtin fields survive
higher-precedence overrides, and updates the affected CLI tests and
snapshots.
Add a shared MiniJinja-based template crate and migrate workflow prompts,
imports, hooks, and InterpString env references to the new {{ ... }}
syntax. This also threads typed run inputs through workflow rendering and
updates docs and tests to match the new templating model.
Brings in the events schema v2 work (RunEvent envelope fields, ActorRef,
parallel branch ids, flattened EventEnvelope wire JSON) on top of the
local Stage 6 settings TOML redesign.
Conflict resolutions:
- fabro-types/src/lib.rs: keep new ParallelBranchId re-export from
origin; drop the legacy Settings/ArtifactStorage* re-exports (the
flat Settings struct was deleted in Stage 6.3b).
- fabro-server/src/server.rs: keep new ActorRef import from origin;
drop the unused legacy Settings import that came along with it.
- fabro-api-client/src/models/web-settings.ts: keep our deletion. The
remote modification was an incidental TS-client regeneration that
Stage 6.6 already invalidated by collapsing settings DTOs to a
freeform v2 shape.
- fabro-workflow/src/event.rs: rewrite the run_created actor test to
use SettingsFile::default() instead of the deleted Settings type.

`--goal-file` was broken in the v2 path: `TryFrom<&RunArgs> for ConfigLayer`
did `let _ = &args.goal_file;`, so clap accepted the flag listed in
`--help` and then silently dropped it. Users running
`fabro run demo --goal-file prompts/goal.md` ended up with no goal at
all (or the DOT graph-level fallback), a regression from the legacy
flat `Settings` shape.
This commit adds first-class support for both inline and file-sourced
goals via a tagged union on `run.goal`. Greenfield decisions:
- **Single field, two variants.** `RunGoalLayer` is an untagged enum
of `Inline(InterpString)` and `File { file: InterpString }`. Makes
`goal XOR goal_file` un-representable in the type system and lets
the v2 merge matrix treat `run.goal` as a single scalar
(last-writer-wins) instead of needing a custom mutual-exclusion
merge rule. Matches the existing `DaytonaDockerfileLayer` pattern.
- **Relative paths are anchored at the file that declared them.**
`ConfigLayer::load(path)` walks the just-parsed `SettingsFile` and
rewrites any literal relative `run.goal.file` path to absolute
using `path.parent()` as the base, via new
`fabro_config::config::resolve_goal_file_paths`. CLI-sourced paths
via `--goal-file` are anchored at CWD in
`overrides::goal_layer_from_args`. Env-interpolated paths
(`${env.GOALS_DIR}/goal.md`) are left unresolved until consume time
and then resolved against the run's working_directory.
- **New accessors, no shims.**
- `run_goal_layer() -> Option<&RunGoalLayer>` — raw variant access.
- `run_goal_inline_str() -> Option<String>` — inline-only, returns
`None` for file-sourced goals.
- `resolve_run_goal(base_dir) -> Result<Option<ResolvedRunGoal>>` —
reads the file from disk if needed, returns text + provenance
(`ResolvedGoalSource::Inline | File { path }`).
- New `ResolveGoalError` enum covers env-lookup and I/O failures.
- Old `run_goal() / run_goal_str()` are **deleted** outright; every
call site has been updated to pick the right variant.
- **CLI wiring (the actual bug fix).** `overrides::goal_layer_from_args`
replaces the two `let _ = &args.goal_file;` lines with real
resolution: `(Some(text), None)` → `Inline`, `(None, Some(path))` →
`File { file: absolute }`. Both-set is rejected by a helper error
and clap already had `conflicts_with = "goal"` as a belt-and-
braces check. Applied to both `RunArgs` and `PreflightArgs`.
- **Manifest builder.** `resolve_manifest_goal` now calls
`args_layer.as_v2().resolve_run_goal()` and
`settings.resolve_run_goal()` in precedence order, then falls
through to the graph-level `@file` sugar if both are absent. The
resolved goal is translated to a `ManifestGoal { text, type_, path }`
by a new `resolved_goal_to_manifest` helper — inline goals get
`type = Value`, file-sourced goals get `type = File` with the
absolute path echoed for provenance.
- **Workflow pipeline.** `fabro-workflow::operations::source::
resolve_goal_override` is rewritten to use `resolve_run_goal`
against the working_directory. The orphaned helper `resolve_goal_file`
(a stub from Stage 4 that was always called with `None`) is
deleted.
- **Server-side manifest.** `fabro-server::run_manifest::
prepare_manifest` stores the CLI-resolved goal as
`RunGoalLayer::Inline`, matching the Stage 4 plan's "CLI owns goal
file reads; server never touches the filesystem for goals"
contract.
## Tests
**Schema** (`fabro-types::settings::accessors`):
- `run_goal_inline_str_returns_source_value` — literal inline variant
- `run_goal_inline_str_is_none_for_file_variant` — file variant
explicitly yields `None` from the inline accessor
- `resolve_run_goal_reads_file_variant_from_disk` — end-to-end file
read with provenance assertion
- `resolve_run_goal_inline_passes_text_through` — inline passthrough
**Config load** (`fabro-config::config`):
- `parse_accepts_inline_goal` + `parse_accepts_file_variant`
- `parse_rejects_goal_with_unknown_sibling_fields` — untagged enum
correctly rejects mixed-shape TOML
- `combine_replaces_file_goal_with_inline_from_higher_layer` and the
reverse — confirms the tagged union merges as a single scalar with
no custom rule needed
- `load_rewrites_relative_goal_file_to_absolute`
- `load_leaves_absolute_goal_file_untouched`
- `load_leaves_env_interpolated_goal_file_untouched`
**CLI overrides** (`fabro-cli::commands::run::overrides`):
- `goal_and_goal_file_together_is_rejected`
- `goal_file_is_anchored_at_cwd_when_relative`
- `absolute_goal_file_is_preserved`
- `inline_goal_builds_inline_variant`
- `empty_args_produce_no_goal_layer`
**CLI integration** (`fabro-cli::tests:🇮🇹:cmd::run`):
- `dry_run_with_goal_file_reads_contents_into_goal` — end-to-end
`fabro run --dry-run --auto-approve --goal-file <path>` and asserts
the file contents appear in the preflight summary. Explicit
regression test for the silently-ignored flag.
- `dry_run_rejects_goal_and_goal_file_together` — clap conflicts_with
## Callsite churn
Every `run_goal() / run_goal_str()` call site updated:
- `fabro-config/src/effective_settings.rs` — 2 test assertions →
`run_goal_inline_str()`
- `fabro-cli/tests/it/cmd/{config,create}.rs` — 3 sites → inline
- `fabro-cli/src/manifest_builder.rs` — rewritten to use
`resolve_run_goal`
- `fabro-workflow/src/operations/create.rs` — 2 sites, test + set
- `fabro-workflow/src/operations/source.rs` — rewritten
- `fabro-server/src/{run_manifest,server}.rs` — set + test assertion
3,782 workspace tests pass (was 3,765, +17 new). `cargo fmt
--check --all` and `cargo clippy --workspace -- -D warnings` are
clean.

Populate stage_id / parallel_group_id / parallel_branch_id on every
event tied to a concrete stage execution, per the spec at
docs-internal/fabro-event-schema-v2-concrete-shape.md:223-279.
Before this commit, stored_event_fields() only set stage_id for the
four Event::Stage* variants and Event::Agent -- the only variants
that carried visit/parallel_group_id/parallel_branch_id in their
payload. Every other stage-scoped event (Checkpoint*, PromptCompleted,
Command*, AgentCli*, Prompt, Interview*, Failover, StallWatchdog,
GitCommit, ArtifactCaptured) fell through to node_stored_fields()
and left stage_id as None.
New approach: scope is carried alongside the event, not on the
variant.
- fabro-workflow/src/event.rs: new StageScope type
{ node_id, visit, parallel_group_id, parallel_branch_id }. New
Emitter::emit_scoped(&event, &scope) for stage-level emission.
to_run_event_at and stored_event_fields take an
Option<&StageScope> that merges into the returned envelope
fields. StageScope::for_handler(context, node_id) is the
canonical handler-side constructor -- prefers
context.current_stage_scope() set by the fidelity lifecycle,
falls back to a scope synthesized from the node_id + context
visit count for tests that don't go through the full lifecycle.
- fabro-workflow/src/context.rs: new
WorkflowContext::current_stage_scope() method reads CURRENT_NODE,
internal.node_visit_count, internal.parallel_group_id,
internal.parallel_branch_id from the context.
- Remove the now-redundant visit/parallel_group_id/parallel_branch_id
fields from Event::Stage{Started,Completed,Failed,Retrying} and
the parallel_* fields from Event::Agent. These existed only to
feed stored_event_fields() and are obsolete once scope is
threaded through the emitter.
Emission site migration (all stage-scoped handlers now use
emit_scoped):
- lifecycle/event.rs: StageStarted, StageCompleted, StageFailed,
StageRetrying, CheckpointCompleted, GitCommit (from on_checkpoint)
- lifecycle/git.rs: CheckpointFailed
- lifecycle/artifact.rs: ArtifactCaptured
- handler/command.rs: CommandStarted, CommandCompleted
- handler/prompt.rs: Prompt, PromptCompleted
- handler/agent.rs: Prompt, PromptCompleted
- handler/fan_in.rs: Prompt, PromptCompleted
- handler/human.rs: InterviewStarted, InterviewTimeout,
InterviewInterrupted, InterviewCompleted
- handler/llm/api.rs: Failover, Agent (via spawn_event_forwarder
which now carries a StageScope across the tokio::spawn boundary)
- handler/llm/cli.rs: AgentCliStarted, AgentCliCompleted
- handler/parallel.rs: ParallelBranchStarted, ParallelBranchCompleted
StallWatchdogTimeout stays on plain emit() because the watchdog
fires from an error path without a live stage context.
Deleted the local StageEventScope struct + current_stage_event_scope
helper from handler/llm/api.rs; it's generalized into StageScope.
Tests: two new unit tests in event.rs --
stage_scope_populates_stage_id_on_non_stage_events verifies
CommandStarted / Prompt / GitCommit all pick up stage_id from scope,
run_level_events_without_scope_leave_stage_id_absent confirms
run.* events still get no stage scope. Updated all test fixtures
across fabro-workflow, fabro-cli to drop the removed Event variant
fields. Accepted two insta snapshot updates in
fabro-cli/tests/it/cmd/{attach,run}.rs that now include the
formerly-missing stage_id fields on checkpoint and interview events.

Completes the fabro-cli test migration for Stage 6.1. Every test in
`cargo nextest run --workspace` now passes (3,764 passed / 0 failed).
Changes:
- cmd/support.rs: compact_inspect / compact_git_inspect now walk the
v2 tree (/settings/run/goal, /settings/run/sandbox/provider,
/settings/run/model/provider) and derive `dry_run` from the v2
execution mode.
- cmd/attach.rs: the event-log filter strips _version and redacts
settings.cli.target.path to [CLI_SOCKET] so randomized tempdir
sockets don't pollute the snapshot. Insta snapshot accepted.
- cmd/run.rs: same cli.target redaction in the run event filter.
dry_run_persists_event_history_in_store and
json_run_implies_auto_approve_for_human_gates check for
`settings.run.execution.approval == "auto"` instead of
`settings.auto_approve == true`. Insta snapshot accepted.
- cmd/config.rs: parse_settings bridges the v2 YAML output back down
to the legacy flat Settings shape so the existing helper assertions
keep working. settings_fetches_server_settings_and_merges_with_local_config
now asserts the v2 R22 behavior (run.inputs replaces wholesale, so
server-side `server_only` is dropped in favor of project's vars).
settings_uses_fabro_home_for_home_config_resolution walks the v2
JSON paths (cli.output.verbosity, run.model.name).
create_explicit_workflow_path_uses_project_config_relative_to_workflow
asserts against the v2 run-record shape.
- fabro-cli/commands/config/mod.rs: legacy_settings_to_v2 is now a
real (if narrow) reverse bridge covering storage, scheduler, github
integration, slack integration, run.model, run.inputs, and cli
verbosity. Stage 6.6 still replaces this when the API client returns
v2 types natively, but for now the server-side defaults round-trip
through the resolver with enough fidelity to keep the settings
command integration tests honest.

Close out consumer migration with targeted behavior fixes and the
remaining integration-test fixture rewrites. The full workspace
nextest run now reports 3,760 passed / 0 failed / 182 skipped.
Runtime fixes:
- effective_settings::apply_server_defaults now propagates the full
server-side Settings shape (llm, sandbox, setup, checkpoint,
pull_request, artifacts, hooks, mcp_servers, github, slack, fabro)
into the resolved CLI settings, matching the pre-Stage-3 'merge
everything server' behavior for RemoteServer/LocalDaemon modes
- fabro-cli commands/run/overrides: route --verbose through
cli.output.verbosity = verbose instead of a run.metadata stash,
so it resolves to settings.verbose via the bridge
- fabro-server run_manifest manifest_args_layer: same — emit a
CliLayer with cli.output.verbosity rather than stuffing the flag
into run.metadata
- fabro-test settings_storage_dir: detect the managed marker and
return None instead of parsing the injected server.storage.root,
so isolated_server correctly spins up a new storage dir
- fabro-server run_manifest_local_daemon test now passes with full
server-side settings snapshot propagation
Test fixture + assertion updates:
- cmd::config::settings_local_explicit_workflow_path_uses_workflow_project_layers:
assertion updated for v2 R30 whole-list replacement of
run.prepare.steps across layers (only workflow-setup survives)
- cmd::config::create_explicit_workflow_path_uses_project_config_relative_to_workflow:
same correction for the persisted run.settings.setup.commands
- cmd::attach::attach_json_errors_without_prompting_for_human_input
and cmd::run::json_run_implies_auto_approve_for_human_gates: strip
the bridge-emitted settings.server and settings.version fields from
the JSON snapshot so the randomised unix-socket path does not flap
the insta snapshot
- cmd::server_start::concurrent_autostart_converges_on_one_shared_daemon_and_cleans_up:
rewrite the injected settings.toml to v2 shape with
[server.storage] root and [cli.target] type = unix path
- scenario::smoke::attach_smoke_covers_arg_validation_and_remote_server_behaviors:
two [server] target fixtures rewritten to [cli.target]
type = http url
Accepted insta snapshots for attach and run JSON outputs. Workspace
build + clippy both clean under -D warnings.
Wire EventEnvelope now inlines the RunEvent payload fields alongside
seq at the top level of the JSON object. The internal Rust
EventEnvelope { seq, payload } stays structurally unchanged; only the
API/SSE serialization layer flattens for clients.
- OpenAPI spec: add stage_id, parallel_group_id, parallel_branch_id,
tool_call_id, actor to RunEvent; model EventEnvelope as allOf(seq,
RunEvent); introduce ActorRef/ActorKind schemas.
- fabro-server: rewrite api_event_envelope_from_store to merge seq
into the payload JSON value before returning the generated flat
type; remove the now-unused nested ApiRunEvent conversion helper.
- fabro-cli server_client: add wire_event_envelope_into_store helper
that turns flat wire JSON back into fabro_store::EventEnvelope
{ seq, payload } for internal consumers.
- Regenerate progenitor Rust types and typescript-axios client.
- Update demo stubs, SSE tests, CLI test helpers, and insta
snapshots to expect the flattened shape and the new stage_id field.
Incidental: the typescript regeneration also picked up prior-merged
spec fields (ApiQuestion stage/timeout/context, upload manifest
batches, web-settings) that were stale in the TS client.

Stage captured artifacts in per-attempt tempdirs and persist them through an
explicit artifact sink instead of writing into run scratch cache.
Server-managed and test-owned runs now write directly to ArtifactStore, while
CLI worker runs keep the staged upload path. The local run summary now prints
durable artifact identifiers and copy hints rather than scratch-cache paths,
and the run-directory docs and integration coverage were updated to match.
Replace the slow CLI integration tests that waited on worker shutdown
grace periods with focused coverage that still checks the important
behavior. The attach JSON test now finishes the gated run cleanly,
the rm force test uses a mocked server contract, and the Ctrl-C cancel
path is covered at the attach layer instead of through a full live run.
Add a cooperative subprocess cancel control message so cancel and delete
can abort pending interviews without relying only on the 5 second hard
kill fallback.
Replace bin-scoped localhost HTTP tests with command-facing integration
coverage so they run under the intended IT timeout budget without
changing nextest overrides.
Drop the dead artifact storage capability split from run records,
run.created events, and workflow/server create paths. Worker artifact
upload is now unconditional, and tests/snapshots no longer encode a
legacy object-backed distinction.
Persist submitted run manifests and accepted run definitions as SHA256
blob refs on run events, remove workflow_bundle.json from the runtime
path, and stop deleting shared CAS blobs when removing runs.
Drop scratch-only compatibility paths and legacy test scaffolding now that
SlateDB-backed state is authoritative. This removes scratch file fallbacks,
updates docs and UI labels, and moves tests onto durable store-backed helpers.
Guard server worker cleanup against superseded subprocesses so rewind and
resume flows do not append a synthetic failure from an older worker. Update
CLI snapshots for the current interview events and give the shared test
session lock more time to cover daemon startup and shutdown.
Tighten the worker upload path so object-backed runs only fail when an
artifact upload is actually attempted without a token, and update CLI
snapshots for the new artifact storage metadata.
Fold in the workspace test and clippy fixes needed to verify the final
artifact upload implementation cleanly across Rust and web targets.
Store large context payloads in the global CAS and keep durable
checkpoint state as blob://sha256 refs instead of execution-local file
paths. Resolve and materialize blob refs at execution, output, and export
time so resumed and remote runs can read legacy and new artifacts
consistently.
Replace the overlapping usage and cost model with canonical billing
primitives centered on ModelRef, ModelHandle, TokenCounts, and
BilledModelUsage. This also renames the public API and web surface from
usage to billing, removes compatibility aliases, and normalizes provider
usage adapters onto the shared billing vocabulary.
Replay persisted run events for attach requests, keep the SSE stream live
only while the run is active, and close on terminal run events instead of
returning 410 for completed runs.
The CLI now treats premature attach EOF as an error, and the affected
integration tests were stabilized around store-backed event ordering and
recovered rewind timelines.
