Zoom in on the workflow graph in both the workflow diagram page and
run overview page to improve readability of node labels and edges.

Consolidates server-mode documentation into a single page with
standalone vs. server comparison table, setup guide, and cross-references.
Updates how-arc-works, quick-start, and architecture pages to link to
the new canonical page instead of duplicating the comparison table.

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

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

GraphQL client with 6 public functions: execute_graphql, fetch_viewer_id,
create_comment, update_issue_state, fetch_candidate_issues, and
fetch_issues_by_ids. Includes Issue/BlockerRef domain types with manual
normalization from GraphQL JSON responses.

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

Adds a generic SSH sandbox that connects to any user-provided host via
openssh, without VM lifecycle management. Supports git clone with GitHub
App credentials, configurable working directory, and arc cp reconnection.

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.

Replace logo/favicon SVGs with Fabro brick icon wordmark.
Update all page titles, alt text, auth UI copy, and GitHub App name prefix.

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()
from the on_event closure to deduplicate the envelope construction.

Mirrors `arc validate` workflow resolution. Shells out to `dot` (graphviz)
with friendly error if not installed. Supports --format svg|png and -o output path.

Wire ProgressUI and EventEmitter into the retro agent so it shows
stage spinners with nested tool calls, matching the look of agent
nodes in the main workflow.

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
previously showed no output until fully complete. Now a braille spinner
animates while checks run.

Embeds the arc-create-workflow skill files via include_str! and installs them
to user (~/.claude/skills/ or ~/.agents/skills/) or project-level directories.
Supports --dir (claude|agents), --for (user|project), and --force flags.

Add a new section to the branch-loop tutorial showing how to loop a node
exactly N times using a diamond gate with a visit count condition, and
cross-reference it from the context docs.

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
