This PR fixes a bug where workflow TOML configuration (including
`[pull_request]` settings) was silently dropped when running in detached
mode (`fabro run -d`). The root cause was a three-part failure:
`create.rs` checked the raw CLI argument string for a `.toml` extension
instead of the resolved path, so `run.toml` was never written to the run
directory; `RunEngine` always fell back to `graph.fabro` (a DOT file),
causing `prepare_workflow` to return `run_cfg = None` and lose all
TOML-level configuration; and `pull_request`/`asset_globs` fields in
`RunConfig` had no fallback to `run_defaults` when `run_cfg` was absent.
The fix replaces the naive file-copy approach with a proper
serialization pipeline. Rather than copying the raw TOML (which would
contain a `graph` field pointing to a nonexistent file in the run
directory), `create.rs` now calls `write_run_config_snapshot`, which
serializes the already-merged `WorkflowRunConfig` and rewrites the
`graph` field to `"graph.fabro"` — the canonical cached name. This makes
the run directory fully self-contained with all defaults merged,
environment variables resolved, and the graph path correct. `RunEngine`
in `main.rs` now unconditionally points at `run.toml`; a new
`resolve_workflow_source` helper handles the `.toml` path by loading the
config and resolving the graph path, with a backward-compatible fallback
to `graph.fabro` for older detached runs created before this change.
As defense-in-depth, fallbacks to `run_defaults` are added throughout
`run.rs` for `pull_request`, `asset_globs`, `devcontainer`, and
`sandbox.env` — ensuring bare `.fabro` files passed directly still pick
up project-level defaults. Two new unit tests verify the serialization
round-trip (confirming `graph` is rewritten and `pull_request` config is
preserved) and the missing-`run.toml` fallback behavior.

This PR updates subagent ID generation to use short 8-character hex
strings instead of full UUID v4 strings. Previously, subagent IDs were
36-character UUIDs (e.g. `550e8400-e29b-41d4-a716-446655440000`), which
were verbose in CLI output and unwieldy when the LLM needed to reference
them in tools like `send_input`, `wait`, and `close_agent`. The new
format generates IDs like `a3f1b20c` — compact, human-readable, and with
~4 billion possible values, effectively collision-free within a session.
The change is made at the source in `subagent.rs`, where UUID generation
is replaced with `format!("{:08x}",
uuid::Uuid::new_v4().as_fields().0)`. Because IDs are now inherently 8
characters, the display-layer truncations in `cli.rs` (5 occurrences)
and `run_progress.rs` (2 occurrences) are redundant and have been
removed — `agent_id` is used directly in format strings instead of a
`short_id` slice.
### Plan Summary
- **Replace UUID generation** in `subagent.rs`: use the first field of a
UUID v4 formatted as 8-char lowercase hex, yielding IDs like `a3f1b20c`
instead of full 36-char UUIDs
- **Remove `short_id` truncation** in `cli.rs` (5 places) and
`run_progress.rs` (2 places): since IDs are now already 8 chars, the
`let short_id = &agent_id[..8.min(agent_id.len())]` pattern is
eliminated and `{agent_id}` is used directly in all format strings
- No test changes required — existing tests use hardcoded IDs like
`"sa-1"` and don't assert on ID length or format
<details>
<summary>Full plan</summary>
````md
The plan has been written to `/home/daytona/workspace/plan.md`.
It covers:
- **4 files to modify**: `fabro-agent/Cargo.toml` (add `rand` dep), `subagent.rs` (replace UUID with 8-char hex), `cli.rs` (remove 5 `short_id` truncations), `run_progress.rs` (remove 2 `short_id` truncations)
- **Step-by-step implementation** with exact line references and before/after code
- **Verification commands** to confirm correctness
- **Test case analysis** explaining why no test changes are needed

This PR introduces a unified `WorktreeSandbox` type in `fabro-sandbox`
that consolidates previously duplicated git worktree management logic
spread across `parallel.rs` and `run.rs`. The new type wraps any
`Arc<dyn Sandbox>`, handles the full worktree lifecycle (branch
creation, `worktree add`, and cleanup) in its `initialize()`/`cleanup()`
methods, overrides `working_directory()` and `exec_command()` to default
to the worktree path, and delegates all other `Sandbox` methods to the
inner sandbox. A `WorktreeConfig` struct controls behavior (branch name,
base SHA, worktree path, and a `skip_branch_creation` flag for resume
flows), and a `WorktreeEventCallback` mechanism bridges lifecycle events
to the workflow event system via a new
`EventEmitter::worktree_callback()` helper.
The old private `WorktreeSandbox` struct in `parallel.rs` (which only
redirected `exec_command` working dirs with no lifecycle awareness) is
removed and replaced with the shared implementation. The
`setup_worktree()` function in `run.rs` is also removed; its logic is
absorbed directly into the `SandboxProvider::Local` branch of sandbox
construction, where `WorktreeSandbox::initialize()` is called and
`std::env::set_current_dir()` follows on success. The resume path
(`run_from_branch`) similarly replaces direct `git::replace_worktree`
calls with `WorktreeSandbox` using `skip_branch_creation: true`. The
`MockSandbox` in `test_support.rs` gains `captured_commands` and
`captured_working_dirs` vectors to support sequenced-command assertions
in the new unit tests.
The `MockSandbox` enhancement is a notable improvement for testability
beyond this specific change—having the full ordered sequence of commands
rather than just the last one makes it straightforward to assert on
multi-step git workflows. One subtle behavior worth noting is that in
`parallel.rs` the `git reset --hard` step previously present after
worktree creation is now absent from `WorktreeSandbox::initialize()`;
the plan mentioned it but the implementation deliberately omits it (the
branch is already force-set to the target SHA, so the reset was
redundant for the parallel case). Cleanup for parallel branches
continues to go through `engine::git_remove_worktree` on the parent
sandbox rather than calling `wt_sandbox.cleanup()`, since the sandbox
`Arc` is consumed by the spawned task—this is a reasonable tradeoff
noted in the plan.

This PR decomposes `fabro run` into three composable primitives —
`create`, `start`, and `attach` — following the Docker-style lifecycle
model. Previously, `fabro run` performed everything in a single
monolithic function, and `--detach` was implemented by reconstructing
CLI argv to spawn a child process, which was brittle and hard to extend.
The new architecture cleanly separates concerns: `fabro create`
allocates the run directory and persists a `RunSpec` struct to
`spec.json`; `fabro start` spawns a detached `_run_engine` process (a
hidden internal command that reads `spec.json`) via `setsid`; and `fabro
attach` tails `progress.jsonl` with live rendering and handles
file-based interview IPC. `fabro run` is now a composition of these
three primitives, and `fabro run --detach` simply skips the attach step.
The main rendering work lives in a new `handle_json_line()` method on
`ProgressUI` that parses JSONL envelopes and dispatches to the same
internal rendering methods already used by the in-process event handler.
This preserves 100% rendering fidelity without duplicating
spinner/stage/tool-call logic — the attach loop just feeds file lines
into the same code paths. File-based interview IPC is handled in the
attach loop itself: it watches for `interview_request.json`, prompts the
user via `ConsoleInterviewer`, and writes `interview_response.json` back
for the engine to consume. The `hide_bars`/`show_bars` methods
previously private to `ProgressAwareInterviewer` are promoted to public
methods on `ProgressUI` and reused in both the attach loop and the
existing in-process interviewer.
The old `detach_run()` function in `main.rs`, which reconstructed argv
by string-scanning `std::env::args()`, is deleted entirely and replaced
by the `create` + `start` composition. New tests cover the
`handle_json_line` dispatch paths (stage started/completed, tool calls,
retro events, invalid input) and the CLI argument parsing for the new
command variants.

This PR adds a `fabro wait` subcommand that blocks until a workflow run
reaches a terminal state and exits with a code reflecting the outcome —
analogous to `docker wait`. The command accepts a run ID prefix or
workflow name, polls `status.json` at a configurable interval
(defaulting to 1 second), and exits 0 on success or 1 on failure/dead.
An optional `--timeout` flag causes the command to bail with an error
message if the deadline is exceeded before the run completes.
The implementation reuses existing infrastructure throughout:
`resolve_run()` for run ID/name resolution, `RunStatusRecord::load()`
and `RunStatus::is_terminal()` for polling, `Conclusion::load()` for
retrieving duration and cost after completion, and `Styles` for colored
terminal output. Human-readable status is written to stderr (preserving
stdout for data), while `--json` mode writes structured conclusion data
to stdout. Missing status files are treated as `Dead` to handle orphaned
runs gracefully. No new dependencies were required.
The change is registered in all three necessary locations:
`commands/mod.rs`, the `Command` enum in `main.rs`, the command name
mapping, and the dispatch match arm. Unit tests cover JSON output across
all terminal states (with and without conclusion data), the
human-readable output path, immediate-terminal poll behavior, and the
missing-file fallback to `Dead`.

Extract the Sandbox trait, types, and all sandbox implementations from
fabro-agent and four separate crates (fabro-exe, fabro-ssh, fabro-sprites,
fabro-daytona) into a single fabro-sandbox crate. This cleans up the
dependency graph — implementation crates no longer pull in the full
fabro-agent just for the trait.
The new crate uses feature flags (local, docker, ssh, exe, sprites,
daytona, test-support) to gate each implementation. The shell_quote()
helper is unified into a single shared implementation, eliminating four
duplicate copies.
fabro-agent now re-exports all sandbox types from fabro-sandbox for
backward compatibility. The four absorbed crates are removed.

doctor and provider_auth used cheapest_model (gpt-5-mini) for connectivity
probes, but gpt-5-mini is rejected by the ChatGPT/Codex backend. Adds
probe_model_for_provider() which returns gpt-5.4-mini for OpenAI and falls
back to the default model for other providers.

Replace fully-qualified fabro_workflows::GitSyncStatus paths with a
use import, and consolidate the near-duplicate dirty-worktree warning arms
into a single block that varies only the environment name.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The git sync check and auto-push logic was gated on should_create_worktree,
which was always false for remote sandboxes. This meant Daytona/Exe/SSH runs
silently proceeded without verifying commits were pushed or warning about
uncommitted changes. Replace the git_clean boolean and should_create_worktree
boolean with two enums (GitSyncStatus: Synced/Unsynced/Dirty and
WorkdirStrategy: LocalDirectory/LocalWorktree/Cloud) so every combination
is handled explicitly via match arms. Also display the base commit SHA for
cloud runs.

- Extract git_repo_root() helper in init.rs (was duplicated between
run_init and run_deinit)
- Fix TOCTOU in run_deinit: remove .exists() check, handle NotFound
from remove_file directly
- Change dotenv::remove_env_key() to return Option<String> so callers
don't need to separately parse the file to check key existence
- Remove merge_env wrapper in install.rs, call shared function directly
- Remove duplicate merge_env tests from install.rs (already in dotenv.rs)

Route OpenAI OAuth users through the ChatGPT Codex backend API with
required headers (ChatGPT-Account-Id, originator). The Codex endpoint
requires streaming-only requests, omits unsupported fields (temperature,

persists the account ID from OAuth tokens and updates CLI docs for
`fabro ps -q`.

When `auto_merge = true` is set in `[pull_request]` config, Fabro enables
GitHub's auto-merge on created PRs using the `enablePullRequestAutoMerge`
GraphQL mutation. Auto-merge implies `draft = false` since GitHub doesn't
allow auto-merge on draft PRs. A `merge_strategy` field (squash/merge/rebase,
default squash) controls the merge method. Failures to enable auto-merge
(e.g. repo doesn't have the setting enabled) warn but don't fail the run.

This PR adds a `fabro upgrade` command that downloads and installs new
releases from GitHub, along with a passive daily auto-check that
notifies users when a newer version is available. The upgrade flow
supports two download backends: the `gh` CLI (preferred, for auth and
rate-limit benefits) with an automatic fallback to plain HTTPS via
`reqwest` when `gh` is missing or not authenticated. The command
includes SHA256 checksum verification, atomic binary replacement with
rollback on failure, downgrade protection with interactive confirmation,
and `--dry-run`/`--force` flags.
A background upgrade check runs automatically on common commands (`run`,
`exec`, `init`, `install`), caching results in
`~/.fabro/last_upgrade_check.json` to avoid hitting GitHub more than
once per 24 hours. Users can disable this via `upgrade_check = false` in
`~/.fabro/cli.toml` or the `--no-upgrade-check` global flag. The check
is spawned as an async task and its notice prints to stderr after the
main command completes, ensuring it never blocks or breaks normal
operation—all errors are silently swallowed.
The implementation follows a test-first approach with unit tests
covering platform detection, version parsing, SHA256 verification,
upgrade check state serialization/staleness, and the new `upgrade_check`
config field. Dependencies `tempfile` (promoted from dev-dependencies)
and `sha2` are added to `fabro-cli`.

This PR adds a new `fabro fork` subcommand that creates a new run
branching from an existing run at a specific checkpoint, without
modifying the original run. This is a non-destructive alternative to
`fabro rewind` — instead of moving branch refs backward and losing later
checkpoint history, fork preserves the source run entirely and creates
fresh run and metadata branches for the new run.
The implementation heavily reuses existing infrastructure from
`rewind.rs` (timeline building, target resolution, parallel map loading,
prefix-based run ID lookup) and follows the same CLI patterns. The core
`execute_fork` function generates a new ULID, creates a run branch ref
pointing at the target checkpoint's commit, then builds a new metadata
branch containing an updated manifest (with new run ID and branch name),
the original graph, and the checkpoint state from the target commit. It
supports the same target syntax as rewind (`@N`, `node_name`,
`node_name@N`), defaults to the latest checkpoint when no target is
specified, and optionally pushes new branches to the remote.
The PR also makes `load_parallel_map` public in `rewind.rs` so fork can
reuse it, and includes five tests covering run branch creation, metadata
branch correctness, preservation of the original run, default-to-latest
behavior, and forking at a specific ordinal.

This PR introduces `fabro-beastie`, a new cross-platform idle sleep
prevention crate (named after Beastie Boys — *No Sleep Till Brooklyn*),
and wires it into `fabro-cli` behind an opt-in `sleep_inhibitor` Cargo
feature. Long-running `fabro run` and `fabro exec` commands can be
killed by OS idle sleep, so when the feature is compiled in and
`prevent_idle_sleep = true` is set in `cli.toml`, an RAII guard keeps
the system awake for the duration of the command.
The `fabro-beastie` crate provides platform-specific backends: on macOS
it uses IOKit power assertions (`PreventUserIdleSystemSleep`), on Linux
it spawns `systemd-inhibit` (with `gnome-session-inhibit` as fallback)
and sets `PR_SET_PDEATHSIG` to prevent orphaned processes. Both fall
back to a no-op dummy backend if the platform backend is unavailable.
The public API is a single `guard(bool)` function returning an
`Option<SleepInhibitorGuard>` that releases on drop.
On the integration side, a `prevent_idle_sleep` boolean field is added
to `CliConfig` (defaulting to `false`), and `cfg`-guarded sleep guards
are placed at the entry points of both the `exec` and `run` command
paths in `fabro-cli`. Since the feature is off by default, there is zero
impact on normal builds — `fabro-beastie` is only pulled in when
explicitly enabled via `--features fabro-cli/sleep_inhibitor`.

Adds `fabro rm <RUN>...` to remove specific runs (the `docker rm` equivalent).

Replace the 3-variant RunStatus enum (Concluded/Running/Unknown) with an
8-variant state machine (Submitted/Starting/Running/Paused/Removing/
Succeeded/Failed/Dead) persisted as status.json via RunStatusRecord.
Add StatusReason enum for fine-grained failure/success classification
(WorkflowError, Cancelled, SandboxInitFailed, Completed, etc.) and
validated state transitions via can_transition_to()/transition_to().
Map engine results to appropriate RunStatus+StatusReason at all write
sites: Submitted (detach), Starting+SandboxInitializing (run init),
Failed+SandboxInitFailed (scopeguard), Running (engine start), and
Succeeded/Failed with reason (engine completion).

Runs were invisible in `fabro ps` during sandbox initialization because
manifest.json isn't written until engine.run(). status.txt is written

This PR enriches the `fabro ps` output with colored status indicators,
duration/cost columns, relative timestamps, and pagination controls.
Status values are now color-coded (green for success, red for fail, cyan
for running, dim for unknown), the header row is bolded, and
separators/labels are dimmed.
Duration and total cost are now extracted from `conclusion.json` and
displayed as new columns. Start times are shown as human-friendly
relative strings (e.g., "2m ago", "3h ago") instead of raw RFC 3339
timestamps, with full timestamps preserved in `--json` output.
New `--limit N` (default 10) and `--all` flags cap the displayed output,
with a footer indicating how many runs are shown out of the total.
PR: https://github.com/fabro-sh/fabro/pull/2
Write id.txt and touch empty progress.jsonl in detach_run() before
