The extract_status_fields function recognized "outcome" as a field for
detecting status JSON objects but never read its value — LLM responses
like {"outcome": "fail", "failure_reason": "tests failed"} were silently
ignored and the outcome was always Success.
Now extract_status_fields reads the outcome field to set the node status
and failure_reason to populate the failure detail. Also adds a fallback:
if no routing directives are found in the response text, the handler
reads status.json from the sandbox CWD (written by agents that prefer
file output over inline JSON). Response text always takes priority.

Apply the changelog guide across all entries: demote incremental
changes (endpoints, flags, syntax options) from hero sections to
categorized accordion footers (API, CLI, Workflows, Fixes,
Improvements). Combine related hero sections (e.g. three hook types
into one). Add "## More" heading above accordion sections. Group
sidebar navigation by month.

Wrap fixes, improvements, and API changes in Accordion components
so the hero features stay prominent and details are expandable.
Add a changelog writing guide documenting the editorial approach.

Extract all 29 full digraph workflows from docs into test/docs/ with
an extraction script, assemble 7 snippet DOTs from reference pages,
and add a runner script for validate/dry-run/haiku/full phases.
Docs fixes:
- definition-of-done: replace multi-word condition values with
underscored equivalents (parser doesn't support spaces), make
safe-default edges unconditional for fallback coverage
- semantic-port: make fallback edges unconditional on fetch/analyze
nodes so validator doesn't reject all-conditional-edge nodes
All 36 DOTs pass `arc validate`.

The API was returning human-readable strings like "2h ago" and "in 4 hours"
instead of real timestamps. The frontend now formats these for display using
timeAgo() and a new timeUntil() helper.

Add 17 new sub-schemas (ModelReference, WorkflowReference, RunReference,
RepositoryReference, CategoryReference, TokenUsage, CodeLocation, RunError,
RunPullRequest, RunTimings, SandboxResources, RunSandbox, RunQuestion,
AggregateUsageTotals, WorkflowSchedule, WorkflowLastRun, UsageStageRef)
and restructure 11 existing schemas to use them, improving evolvability
by grouping related fields into nested objects.

annotations, extracted parameters, discriminated unions, and richer
response schemas — matching the patterns already established for
Sessions.
Structural changes:
- Extract CancelRunResponse and SteerRunResponse from inline schemas

VerificationSlug, InsightQueryId, ProjectId, CheckpointFilter)
- Enrich existing RunId, PageLimit, PageOffset parameters
- Add descriptions + examples to all ~66 schemas and ~200+ properties
- Add operation descriptions to all ~35 endpoints
Rust handler updates:
- Change ManagedRun.created_at from Instant to chrono::DateTime<Utc>
- Populate new fields in StartRunResponse, RunStatusResponse
- Use new StageTurn discriminated union variants in demo data
- Update demo data timestamps to use DateTime<Utc>

Add three new pages under a "Using the API" group in the API Reference

versioning), Demo Mode, and Client SDKs. Nest "Run Internals" as an
expandable sub-group under "Run Outputs" in the nav.

Replace the server-level `--demo` flag with per-request demo dispatch.
The Rust API builds both a demo and real router; incoming requests with
the `X-Arc-Demo: 1` header hit the demo router (auth disabled, static
data), all others hit the real router with normal auth.
The React web app gets a beaker icon toggle in the top nav bar (next to
the theme toggle) that sets an `arc-demo` cookie. Loaders read the
cookie to decide whether to send the `X-Arc-Demo: 1` header to the API.
The `ARC_DEMO=1` env var still works as a default when no cookie is set.

Replace `gh auth token` with GitHub App IATs scoped to `contents: read` for
Daytona sandbox git cloning. Public repos are auto-detected and cloned without
credentials. Private repos get short-lived, repo-scoped tokens. Clear error
messages for each failure mode (app not installed, suspended, no repo access,
auth failure). Falls back gracefully when no GitHub App is configured.

Revert the graphviz language identifier back to dot (Shiki doesn't

attributes, strings, comments, and operators.
