When a human gate has only a freeform edge and no fixed choices, use
QuestionType::Freeform instead of MultipleChoice. This sends the user
directly to a text input prompt, skipping the unnecessary select menu.
Also removes the Quit choice from the REPL workflow so it uses the new
freeform-only path.

Thread the previous stage's response through `Question.context_display`
so `ConsoleInterviewer` renders it before the interactive prompt. This
lets users see the agent's response before deciding what to do next in
looping workflows like REPL.

Update default git author to Fabro <noreply@fabro.sh>. Append
"Generated with Fabro" footer to all checkpoint and metadata commits,
and to PR bodies. When the commit author is overridden, add a
Co-Authored-By trailer for attribution.

Rename `llm_model` → `model` and `llm_provider` → `provider` in stylesheet
properties, accessor methods, and all DOT/doc references. Add
ProviderInferenceTransform that automatically infers provider from the model
catalog, eliminating redundant provider declarations in stylesheets.

Allows users to specify a reachable base URL for SSH hosts so that
get_preview_url(port) returns the correct external URL instead of

Replace docs/images screenshots (runs-board, run-detail, workflow-example)
with fresh captures from the current FABRO-branded UI in demo mode.
Also fix a panic in arc-api demo::run_config_to_api where None-valued
HashMap fields (e.g. sandbox.env) serialized to JSON null, which failed
to deserialize into non-optional HashMap fields in RunConfiguration.
Added strip_nulls helper to clean the intermediate JSON value.

- Add `client: reqwest::Client` field (matches LinearTracker pattern); eliminates 7 per-call client constructions that prevented connection pool reuse
- Remove `graphql_url: String` field — always derivable from base_url, computed via `graphql_url()` method at each call site
- Extract `make_test_issue()` test helper to replace 3 copy-pasted Issue struct literals

- New arc-tracker crate defines the Tracker trait and shared Issue/BlockerRef types
- arc-linear: replace Issue/BlockerRef with arc-tracker re-exports, add LinearTracker struct implementing Tracker, remove free functions
- arc-github: add GitHubTracker implementing Tracker via Projects V2 GraphQL API, with lazy project node ID resolution (org → user fallback) and create_installation_access_token_for_projects helper
- 47 tests in arc-github (15 new), 24 tests in arc-linear (updated to use LinearTracker)

- Make execute_graphql private (callers use domain functions)
- Extract extract_issues() helper to deduplicate node-parsing blocks
- Replace O(n^2) .find() loop with HashMap for ID-ordered results
- Add tracing::debug on all public functions, warn on HTTP errors

The inherent method shadowed the identical Sandbox trait method,
creating a risk of subtle divergence if one were changed without
the other.

Extract duplicated compaction check+trigger blocks in the session loop into
Session::compact_if_needed(). Replace the hardcoded 20_000 token budget with
COMPACTION_USER_MESSAGE_TOKEN_BUDGET constant. Change extract_recent_user_messages
to take ownership of discarded turns instead of borrowing and cloning.

Reframe the summarization prompt as creating a handoff for a different assistant
(rather than self-summarization) to produce more thorough, explicit summaries.
Add a pre-turn compaction check so context is trimmed before building the LLM
request, not just after. Extract recent user messages from discarded turns during
compaction so the model retains the user's actual words alongside tool call/result
pairs.

A workflow run hung for 33 minutes in a Daytona shell command despite
a 5-minute client-side timeout in tokio::select!. The root cause is
unknown — tests confirm the select pattern works correctly. Adding
info-level tracing at method entry (with command and timeout_ms),
after process service acquisition, and in each select arm so the
next occurrence reveals exactly where execution stalls.

Enable serde_json's preserve_order feature so Map uses insertion-order
IndexMap instead of sorted BTreeMap. Extract build_event_envelope()

Wire ProgressUI and EventEmitter into the retro agent so it shows

Previously, AgentError::Aborted was a bare variant that displayed as
just "Aborted", making it impossible to tell whether a session was
killed by wall clock timeout, user cancellation, or something else.
Now it carries an AbortReason (WallClockTimeout or Cancelled) so
terminal output like the retro agent failure message includes the cause.

The command takes several seconds (especially with live probes) but

Regenerate 2026-03-10 changelog with full commit set (installer, devcontainer
support, arc pr subcommands, --no-dotenv removal). Add 2026-03-11 changelog
for shadow branch run records and arc diff improvements. Update docs: CLI
reference (arc pr list/view/merge/close, --shortstat), devcontainers page
(replace placeholder with full content), run-configuration (devcontainer
field), checkpoints (per-node files on metadata branch), models catalog
(gemini-3.1-pro-preview-customtools). Improve preflight to show per-model
LLM checks instead of a single merged provider line.

Remote sandboxes (Daytona, Exe) clone into their own environment, so
creating a local git worktree is unnecessary. The worktree decision
previously only checked worktree_mode and git_clean, ignoring the
sandbox provider entirely.

When workflow prompts tell agents to write results to a file with
embedded JSON status fields, the engine now falls back to reading the
last file the agent wrote if neither the response text nor status.json
contain extractable status fields.

Store execution trace data (prompts, responses, status, diffs, etc.) on
the shadow branch alongside checkpoint/manifest data. This makes the
shadow branch a complete, self-contained record of each run.
- scan_node_files() scans nodes/ for allowlisted files (<512KB)
- Checkpoint commits now include per-node files
- init_run includes sandbox.json
- Finalize commit after workflow writes retro.json + final node files

Drop `HEAD` from the live diff command so `git diff {base_sha}` compares
against the working tree instead of only committed changes. Extracts
`build_live_diff_cmd` for testability.

Tool output previously showed absolute sandbox paths (e.g.
write_file(/home/daytona/workspace/output/js/physics.js)) because
shorten_path() only checked the host CWD. Now ProgressUI stores the
sandbox working directory and strips it from displayed paths, producing
cleaner output like write_file(output/js/physics.js).

When `arc run` uses a Daytona sandbox, `initialize()` re-detects the
branch from cwd — but by that point the worktree has switched HEAD to
`arc/run/{run_id}`, which was never pushed, causing the clone to fail
with HTTP 400. Pass the already-known base branch (e.g. `main`) from
the caller instead of re-detecting it inside the sandbox.

- Remove `devcontainer_env()` and `resolve_devcontainer()` trivial wrappers,
inline at call sites
- Fix initializeCommand Args quoting: use shlex::try_quote instead of naive join
- Fix initializeCommand silently dropping Parallel commands: now executes them
- Convert three repetitive lifecycle calls to a data-driven loop
- Use crate::millis_u64() in setup command loop for consistency

When `devcontainer = true` in TOML sandbox config, Arc now resolves
devcontainer.json from the repo, uses its Dockerfile for the Daytona
snapshot, runs lifecycle hooks (on_create, post_create, post_start)
in the sandbox, and merges devcontainer env vars under TOML env.

Model list tests (6): exact stdout snapshots in .trycmd files, replacing
insta .snap files. Error validation tests (5): TOML with stderr-to-stdout
checking specific error messages. Doctor tests (3): TOML with env.inherit
= false for env_clear(). Validate tests (7): TOML with fs.cwd/sandbox for
file path access. Dry-run tests (6): TOML with fs.cwd/sandbox. Exec help
and no-prompt tests (2): TOML with env config.
Remaining in cli.rs: negative-assertion tests, file-system side-effect
test, tmpdir+env test, and 11 ignored API-key-dependent tests.

Remote sandboxes clone from origin, so "clean" should mean no uncommitted
changes AND the local branch is pushed. Replaces the hardcoded `false` with
a new `ensure_clean_and_pushed` that reuses `ensure_clean` + `branch_needs_push`.

Activate the dormant Segment-based telemetry infrastructure by wiring
lifecycle events in main.rs. Each CLI invocation now emits a "Command Run"
or "Command Error" event with sanitized args, duration, hashed repo
identifier, and CI detection.
- Add sanitize.rs: redacts sensitive CLI args (paths, values) while
keeping flags, booleans, and numeric patterns
- Add git.rs: MD5-hashes normalized origin remote URL so HTTPS/SSH
variants produce the same identifier
- Extend command_name to include nested subcommands (e.g. "pr create",
"llm prompt", "system prune", "model list")
- Restructure main/main_inner to capture timing and return command name
alongside result for telemetry

Daytona's Rust SDK doesn't support uploading build context files, so
COPY/ADD instructions referencing local files fail at build time with
confusing errors. Detect this early in resolve() and return a clear
UnsupportedCopyAdd error. Multi-stage COPY --from= and ADD http(s)://
are still allowed.
