Enrich the entire OpenAPI spec with descriptions, examples, format
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
- Change POST /runs/{id}/steer from 200 to 202 (async fire-and-forget)
- Split StageTurn into discriminated union (SystemStageTurn,
AssistantStageTurn, ToolStageTurn) with oneOf + discriminator
- Add status + created_at to StartRunResponse
- Add created_at to RunListItem and RunStatusResponse
- Add created_at + updated_at to SavedQuery
- Add format: date-time on RetroListItem.timestamp
- Extract 7 new reusable parameters (StageId, QuestionId, WorkflowName,
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>

Each SSE frame now includes a sequential numeric id: field. Clients can
reconnect with the Last-Event-ID header to resume the stream after the
last received event, skipping already-processed events.

SSE transport-level event names with JSON data payload fields
- Update demo data to use proper UUIDs instead of string IDs
- Add uuid dependency to arc-types crate

Replace `repo` and `time` with ISO 8601 `created_at`/`updated_at`

CreateSessionRequest and add optional `model`. Add descriptions and
examples to all session-related OpenAPI schemas and endpoints.

Add three new pages under a "Using the API" group in the API Reference
tab: API Overview (base URL, authentication, errors, pagination,
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.

Add both models with aliases (gpt54, gpt54-pro). Neither replaces
gpt-5.2 as the OpenAI default. Update fallback chain test since
GPT-5.4 ($2.50) is now closer to Opus ($15) than GPT-5.2 ($1.75).

Per-node `max_visits` now overrides the graph-level `max_node_visits`
(and the dry-run default of 10) for individual nodes, giving tighter
control over specific loops like fix-and-verify cycles.

Revert the graphviz language identifier back to dot (Shiki doesn't
bundle either) and register a custom TextMate grammar via Mintlify's
styling.codeblocks.languages.custom config. The grammar (extracted from
apps/arc-web/app/data/dot-grammar.ts) highlights keywords, shape names,
attributes, strings, comments, and operators.

Changes ```dot to ```graphviz across all docs for better syntax highlighting

The question_type field on ApiQuestion was a bare string serialized via
Debug formatting. Define a proper enum in the spec so typify generates a

Wrap 4 list endpoints that returned bare arrays in the standard
paginated `{ data, meta: { has_more } }` shape so adding real
pagination later is additive rather than a breaking change.
Endpoints: GET /runs/{id}/questions, /runs/{id}/stages,
/runs/{id}/verifications, and /verifications.

Apply the same page[limit]/page[offset] pagination pattern from
GET /runs to: workflows, workflow runs, retros, sessions, projects,
branches, saved queries, query history, and stage turns.
Each endpoint now returns { data, meta: { has_more } } instead of
a bare array. Includes OpenAPI spec updates, demo handler changes,
regenerated TS client, updated frontend consumers, and a new
pagination conformance test.

Runs now go through a state machine (queued → starting → running →
completed/failed/cancelled) instead of spawning immediately. A background
scheduler promotes queued runs when capacity is available, defaulting to
4 concurrent runs. Configurable via --max-concurrent-runs CLI flag or
max_concurrent_runs in server.toml.

Introduce page[limit]/page[offset] query params and { data, meta: { hasMore } }

All API errors now return a consistent JSON shape:
{"errors": [{"status": "4xx", "title": "...", "detail": "..."}]}

handlers and auth extractors. Updates OpenAPI spec and regenerates
