1. Succeeded runs now rejected — a completed run keeps checkpoint.json
around, so resume would happily restart and overwrite start.json and
conclusion.json. Now checks status.json and bails on Succeeded.
2. PID liveness check moved before checkpoint validation. The engine
writes checkpoint.json with a plain fs::write, so a concurrent
resume could see a half-written file and report "corrupt" for a
run that is simply still alive. Order is now: PID → status →
checkpoint parse → cleanup → spawn.

Two issues in the resume cleanup logic:
1. progress.jsonl was not in the stale artifact list, so attach and
logs would replay the previous attempt's events before the new run.
Added it to the cleanup list.
2. Cleanup ran before validating the checkpoint was parseable. A
crash during the original run can leave a truncated checkpoint.json
that passes exists() but fails to parse. We now load and parse the
checkpoint first; if it's corrupt we bail with the old conclusion
and failure evidence intact.

Two bugs from the refactoring:
1. (High) On resume, run_command_impl would create a fresh worktree
with skip_branch_creation=false, force-resetting the run branch
and losing file changes from the original run. Fix: force
workdir_strategy to LocalDirectory when resume=true.
2. (Low) Sleep inhibitor guard was created inside a #[cfg] block
scope, so it was dropped before resume_command ran. Fix: use
`let _guard = { ... }` pattern to keep it alive for the arm.

Resume now follows the same subprocess pattern as run: look up run
directory by ID prefix, validate checkpoint exists, clean stale
artifacts, reset status to Submitted, spawn _run_engine --resume, and
attach. This eliminates ~1600 lines of duplicated env/sandbox setup
from resume.rs.
Key changes:
- operations::start() and operations::resume() take run_dir instead
of Persisted, loading state from disk internally
- run_engine() builds RunOptions from RunRecord on disk, so callers
no longer extract record fields manually
- StartOptions flattened (no more nested InitOptions)
- FabroError::Precondition variant for start/resume guard checks
- _run_engine accepts --resume flag to dispatch to resume path
- operations::restore removed (no longer needed)
- Resume CLI stripped to just <RUN_ID> + --detach

Follow-up to fafc0a3c. Renames local variables, function parameters,
and struct fields that hold renamed types (ExecutorOptions, RunCreateOptions,
RunOptions) from config/settings to options/run_options for consistency.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Standardize naming so all "bag of options" structs use the Options
suffix: ExecutorSettings→ExecutorOptions, RunSettings→RunOptions,
GitCheckpointSettings→GitCheckpointOptions, LifecycleConfig→LifecycleOptions,
RunCreateSettings→RunCreateOptions, StartRetroConfig→StartRetroOptions,
StartFinalizeConfig→StartFinalizeOptions, AutoMergeConfig→AutoMergeOptions.
Also renames the run_settings module to run_options.

operations::create now handles the full pipeline: var expansion, parse,
goal override, transform, validate, config normalization, and persist.
This eliminates duplicated RunRecord construction and pipeline::persist
calls across CLI and API callers.
Key changes:
- Rename operations::create → validate, CreateOptions → ValidateOptions
- New operations::create returns Persisted, with RunCreateSettings
- Add ValidationFailed error variant with diagnostics
- Move normalize_config, default_run_dir into operations
- Delete prepare_workflow, PreparedWorkflow, CliFlags from CLI
- Make pipeline::persist and types module pub(crate)
- API catches both Parse and ValidationFailed as 400
- CLI prints diagnostics directly from error (no re-validation)
- ExecutionOverrides struct replaces 9-param function

Make 7 modules pub(crate) (condition, graph, lifecycle, node_handler,
run_dir) and 4 modules #[doc(hidden)] (artifact, test_support,
transforms, stylesheet) to reduce the public surface of fabro-workflows.
Internal crate::transform alias replaced with crate::transforms.
External consumers still access what they need via narrowed re-exports.

These are purely sandbox concerns — they serialize/deserialize sandbox
connection info and reconstruct sandbox instances. Moving them to
fabro-sandbox improves cohesion and removes workflow-layer coupling
from sandbox lifecycle logic.

The enum had zero internal usage in fabro-workflows and naturally belongs
in fabro-sandbox alongside the sandbox implementations. Removed cfg
gates from the Exe variant (it's just a tag) and added non-exedev
fallback arms in fabro-cli to handle feature unification from fabro-api.

Consolidate all record types under the records module. Files are renamed
to drop the _record suffix (run_record→run, start_record→start,
sandbox_record→sandbox) since the module path provides that context.

Move unit tests from engine.rs to their respective modules:
- 72 tests to graph_ops.rs (retry policy, edge selection, fidelity, thread_id, etc.)
- 5 tests to run_dir.rs (node_dir, visit_from_context)
- 1 test to sandbox_git.rs (git_checkpoint_includes_builtin_excludes)
Fix clippy needless_borrow in pipeline/finalize.rs.

- Rename `settings: mut config` binding to `mut settings` in resume.rs
and update all 8 downstream references
- Deduplicate normalize_config call in run.rs by reusing the result
computed for RunRecord
- Replace expect() with graceful error handling when loading RunRecord
in the API server's execute_run

Phase 5: Rename debug artifacts from run.toml/graph.fabro to
workflow.toml/workflow.fabro. Change write_run_config_snapshot to
byte-for-byte copy of the original TOML instead of re-serialization.
Phase 6: Add run_from_record() that builds execution state directly
from a RunRecord, bypassing prepare_workflow(). Refactor run_command
into run_command + run_command_impl to share execution logic. Simplify
run_engine_entrypoint to call run_from_record() instead of
reconstructing RunArgs and re-parsing the workflow.
Step 7k: Write RunRecord in the API server's execute_run() for
observability, enabling fabro ps/inspect for API-initiated runs.
Fix stale manifest.json reference in docs/agents/outputs.mdx.

Collapse init_run/init_run_with_records/init_run_inner into a single
init_run(run_id, files) that takes all files as a flat slice. Resume
from metadata branch now uses RunRecord's embedded graph directly
when available, falling back to graph.fabro DOT parsing for old runs.

Delete run_spec.rs and manifest.rs modules. Remove write_manifest()
from the engine, update DiskLifecycle and GitLifecycle to only write
StartRecord. Remove read_manifest() from MetadataStore. Update
run_fork to only handle run.json/start.json. Convert resume.rs to
use RunRecord/StartRecord from the metadata branch. Update all tests
and integration tests.

Introduce two new persistence types aligned to the CREATE/START lifecycle:
- RunRecord (run.json): written at CREATE with merged FabroConfig, fully
transformed Graph, and run metadata
- StartRecord (start.json): written at START with start_time, run_branch,
and base_sha
All readers (run_lookup, inspect, diff, pr, attach, detached_support,
start, run_fork, pull_request, run_rewind, resume) now read from the
new types first. Legacy manifest.json + spec.json are still written
for backward compatibility (removal in follow-up).
Also adds dry_run, auto_approve, no_retro fields to FabroConfig, derives
Default on LlmConfig and Graph, and updates docs + tests.

Remove the ContextStore trait, InMemoryStore, and Context::with_store() from
fabro-core — put the HashMap directly in Context. Replace the duplicate
fabro-workflows Context struct with a re-export of fabro_core::Context, and
move domain accessors (fidelity, run_id, preamble, thread_id) to a
WorkflowContext extension trait. Eliminate the bridge layer (WfContextStore,
bridge_context, WorkflowContextExt) entirely since there is now one Context
type. Rename clone_context() to fork() for clarity.

Fill in the previously stubbed ArtifactLifecycle and GitLifecycle, and
complete FidelityLifecycle and CircuitBreakerLifecycle with their full
behavior. Wire the orchestrator with context seeding, shared state, and
all callback orderings matching the plan.
FidelityLifecycle: use resolve_fidelity/resolve_thread_id for full
resolution chains, add preamble building via build_preamble, set
thread.{tid}.current_node key, store raw Edge for proper resolution.
CircuitBreakerLifecycle: add on_edge_selected with TransientInfra guard
and restart_failure_signatures tracking for loop_restart edges.
EventLifecycle: add Skipped guard in after_node (engine.rs:2080 parity),
read GitCheckpointResult for GitCommit/GitPush events in on_checkpoint,
read artifact_store count and last_git_sha in on_run_end.
HookLifecycle: add Skipped guard in after_node, add on_checkpoint for
CheckpointSaved hook.
DiskLifecycle: add on_run_start with write_manifest + write_run_status,
use write_node_status with visit-based directory naming.
GitLifecycle: full implementation — on_run_start resets last_git_sha and
inits metadata branch; on_checkpoint does shadow commit, run branch
commit, checkpoint re-save with SHA, push, and diff.patch; on_run_end
writes final.patch.
ArtifactLifecycle: full implementation — on_run_start swaps fresh store,
before_attempt records epoch, after_attempt collects assets and emits
AssetsCaptured, after_node offloads large values and syncs to sandbox.
Orchestrator: context seeding (mirror_graph_attributes, INTERNAL_RUN_ID,
INTERNAL_WORK_DIR) with is_initial_resume gating, shared state for
checkpoint_git_result/last_git_sha/artifact_store, full callback wiring.
Promote write_manifest, write_node_status, git_diff to pub(crate).
Add Clone to RunConfig. Constructor takes Arc<RunConfig> + is_resume.

Split the 564-line core_adapter/lifecycle.rs into a lifecycle/ directory
with dedicated structs for each domain concern (event, hook, fidelity,
auto_status, circuit_breaker, disk, git, artifact), orchestrated by a
WorkflowLifecycle that enforces explicit per-callback ordering.
Also fixes core adapter boundary gaps:
- Handler now uses per-call snapshot/apply context bridge and real graph
instead of STUB_GRAPH
- Executor::run() returns (Outcome, RunState) so run_via_core can
extract the final context instead of returning an empty one
- run_via_core populates git_state on EngineServices for handlers
- Checkpoint resume gains stage_index, next_node_id fallback, and
node_visits reconstruction for old checkpoints

- Extract format_panic_message() helper, used by both engine.rs and core_adapter
- Add RetryPolicy::DEFAULT_BACKOFF const, replacing 6 identical BackoffPolicy literals

- Replace magic "success" string with StageStatus::Success.to_string()
- Bind graph.stall_timeout() once in run_via_core instead of calling twice
