Keep project config and checked-in workflows under .fabro so they stay out of
normal repo listings. Update config discovery, CLI project commands, fixtures,
docs, and checked-in workflow paths to use .fabro/project.toml and
.fabro/workflows/*.
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.
Rewrite every docs/ reference and integration guide example that
previously showed legacy flat TOML (`[llm]`, `[vars]`, `[sandbox]`,
`[setup]`, `[exec]`, `[fabro]`, `[pull_request]`, `[mcp_servers]`,
`[git]`, `[web]`, `[api]`, `[features] retros`, `version = 1`,
top-level `storage_dir`) to use the v2 namespaced schema. Also update
the surrounding prose to describe v2 merge semantics (R22 run.inputs
wholesale replacement, R71 sticky sandbox.env/labels, R30 whole-list
prepare.steps replacement, hook id-based replacement).
Files touched:
- docs/reference/user-configuration.mdx (complete rewrite around
[cli.*] ownership, [run.*] run-scoped defaults, [cli.target] /
[cli.exec] / [cli.output] / [cli.updates] / [cli.logging], and
[run.agent.mcps.<name>] with durations like "10s")
- docs/reference/cli.mdx (settings.toml example uses [cli.exec.*],
[run.model], [cli.target])
- docs/execution/run-configuration.mdx (full run-config example
rewritten to use [workflow].graph, [run].goal/working_dir,
[run.model], [run.prepare.steps], [run.sandbox.daytona.snapshot]
with Size values, [run.inputs], [run.artifacts], [run.agent.mcps],
[run.pull_request], [[run.hooks]] with optional id and duration
timeout; section docs explain the new merge semantics)
- docs/execution/environments.mdx and devcontainers.mdx (sandbox
examples now use [run.sandbox.*])
- docs/execution/retros.mdx (retros moved to [run.execution] retros
= true per R31)
- docs/execution/failures.mdx (fallbacks now a single ordered array
under [run.model].fallbacks)
- docs/workflows/variables.mdx ([vars] → [run.inputs], wholesale
replacement semantics explained)
- docs/administration/server-configuration.mdx (full reference
rewritten around [server.listen]/[server.api]/[server.web]/
[server.auth]/[server.storage]/[server.scheduler]/[server.logging]/
[server.integrations])
- docs/api-reference/overview.mdx (auth strategies now enabled via
[server.auth.api.jwt].enabled and [server.auth.api.mtls].enabled;
listener TLS moved to [server.listen.tls])
- docs/integrations/daytona.mdx, github.mdx (provider config now
nested under [run.sandbox.daytona] / [server.integrations.github])
- docs/human-tools/ssh-access.mdx (sandbox examples to v2)
- docs/agents/mcp.mdx (Playwright sandbox example to [run.agent.mcps])
- docs/core-concepts/models.mdx (model config and fallbacks array to
[run.model])
Canonical fabro-cli overrides and server run_manifest now emit
verbose via [cli.output].verbosity = verbose rather than the prior
run.metadata staging. No code changes beyond those Stage 4 fixes that
were already in flight.
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.
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.
- centralize FABRO_HOME and storage path resolution in fabro-config
- rename store types, extract ArtifactStore, and simplify run key layout
- switch run scratch to scratch/, remove RuntimeState, and refresh docs/clients
Consolidate CLI and server machine defaults under settings.toml,
including loader renames, writer preservation fixes, same-machine
manifest handling, and docs/test updates for the new config model.
Update the run directory, context, and output docs to describe
large offloaded values as file-backed artifacts while preserving the
existing cache path examples.
Restructure the flat `serve` command into a nested `server start`
subcommand, following the existing namespace pattern (system prune,
repo init, etc.).

These commands all operate on a run's sandbox environment. Grouping them
under `fabro sandbox` makes the mental model clear and avoids confusion
with `fabro asset cp`.

Preflight validation is conceptually distinct from running a workflow —
it deserves its own top-level command rather than being a flag on `run`.
- Add `PreflightArgs` struct and `Commands::Preflight` variant
- Create `commands/preflight.rs` with dedicated `execute()` function
- Remove `--preflight` flag from `RunArgs`
- Refactor `load_workflow_source_input` to take individual params
instead of `&RunArgs`
- Refactor `resolve_cli_goal` to take `Option<&str>` / `Option<&Path>`
- Refactor `run_preflight` to take `cli_model`/`cli_provider` instead
of `&RunArgs`, make `pub(crate)`
- Update docs and skills references

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

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.

Context::append_log / logs_snapshot was a write-only audit trail that
was never surfaced — not in events, CLI output, or tracing. Errors like
"checkpoint save failed" were silently swallowed.
Replace all append_log call sites with RunNotice events (which are
automatically traced and visible in progress.jsonl / CLI). Remove the
logs field from both Context types, the Checkpoint struct, the OpenAPI
spec, and the TS client. Old checkpoints containing a logs field are
silently ignored during deserialization.
Also make git_diff return Result<String, String> with structured error
info (exit code + stderr) instead of Option<String>.

Update references to WorkflowRunConfig, ServerConfig, apply_defaults,

Remove ErrorPolicy enum (continue/fail_fast/ignore) and the k_of_n/quorum
join policies from the parallel handler, leaving only wait_all and
first_success. This deletes ~180 lines of conditional logic including
FailFast early termination, the ParallelEarlyTermination event, and all
related tests and documentation.

- Remove any-edge fallback from select_edge() in deterministic mode; random
mode retains it as an enhancement over the base spec
- Restrict preferred_label and suggested_next_ids matching to unconditional
edges only (already applied in prior work, tests added here)
- Rename default_max_retry → default_max_retries across codebase (code, docs,
fixtures, skills) and change default from 3 to 0
- Update transitions.mdx to document edge selection cascade accurately

Introduce a reusable Warning { kind, message, details } variant in
AgentEvent so non-fatal warnings (context window usage, deprecation,
etc.) share a single event shape. The context_window warning preserves
all original fields inside the JSON details object.

## Summary
- **Unify foreground and detach code paths**: Both `fabro run` modes now
go through the same `create_run() + start_run()` pipeline, with
foreground adding `attach_run()`. Only `--preflight` remains as a
special case.
- **Fix three bugs in create→start→attach path**: (1) `_run_engine`
crashed for `.fabro` workflows by hardcoding `run.toml` — now falls back
to `graph.fabro`; (2) `attach_run` couldn't detect crashed engines due
to zombie processes — `start_run` now returns the `Child` handle; (3)
`create_run` ignored `--run-id`.
- **Configure nextest slow-timeout profiles**: Tighten unit test timeout
to 2s slow / 4s kill, add `e2e` profile with 10s/30s. Switch CI and docs
to `cargo nextest run`.
## Test plan
- [ ] `cargo nextest run --workspace` passes with new timeout profiles
- [ ] `fabro run <workflow>` works in foreground mode (create + start +
attach)
- [ ] `fabro run --detach <workflow>` prints run ID and exits
- [ ] `fabro attach <run>` works standalone (without child handle)
- [ ] `fabro resume <run>` works for both `.toml` and `.fabro` workflows

New page (execution/outcomes.mdx) defines the 5 stage statuses, documents
how each handler produces them, and explains allow_partial, auto_status,
the retry loop, goal gate interaction, and outcome in edge conditions.
Existing pages updated: added missing `skipped` status to outcome key
descriptions, improved `goal_gate`/`auto_status` descriptions in the
dot-language reference, added `allow_partial` to the attributes table,
and added cross-links from failures.mdx and transitions.mdx.

Roadmap: replace placeholder items with current shipped/building/planned
features. Use real dates for sorting instead of manual sortOrder. Fix
UTC timezone rendering for date display.
Terminology: replace all standalone "DOT" references with "Graphviz" or
"Graphviz DOT" across docs, marketing, README, AGENTS.md, and OpenAPI
spec. Changelogs left unchanged as historical records.
