Rewrite every docs/ reference and integration guide example that
previously showed legacy flat TOML (`[llm]`, `[vars]`, `[sandbox]`,
`[setup]`, `[exec]`, `[fabro]`, `[pull_request]`, `[mcp_servers]`,
`[git]`, `[web]`, `[api]`, `[features] retros`, `version = 1`,
top-level `storage_dir`) to use the v2 namespaced schema. Also update
the surrounding prose to describe v2 merge semantics (R22 run.inputs
wholesale replacement, R71 sticky sandbox.env/labels, R30 whole-list
prepare.steps replacement, hook id-based replacement).
Files touched:
- docs/reference/user-configuration.mdx (complete rewrite around
[cli.*] ownership, [run.*] run-scoped defaults, [cli.target] /
[cli.exec] / [cli.output] / [cli.updates] / [cli.logging], and
[run.agent.mcps.<name>] with durations like "10s")
- docs/reference/cli.mdx (settings.toml example uses [cli.exec.*],
[run.model], [cli.target])
- docs/execution/run-configuration.mdx (full run-config example
rewritten to use [workflow].graph, [run].goal/working_dir,
[run.model], [run.prepare.steps], [run.sandbox.daytona.snapshot]
with Size values, [run.inputs], [run.artifacts], [run.agent.mcps],
[run.pull_request], [[run.hooks]] with optional id and duration
timeout; section docs explain the new merge semantics)
- docs/execution/environments.mdx and devcontainers.mdx (sandbox
examples now use [run.sandbox.*])
- docs/execution/retros.mdx (retros moved to [run.execution] retros
= true per R31)
- docs/execution/failures.mdx (fallbacks now a single ordered array
under [run.model].fallbacks)
- docs/workflows/variables.mdx ([vars] → [run.inputs], wholesale
replacement semantics explained)
- docs/administration/server-configuration.mdx (full reference
rewritten around [server.listen]/[server.api]/[server.web]/
[server.auth]/[server.storage]/[server.scheduler]/[server.logging]/
[server.integrations])
- docs/api-reference/overview.mdx (auth strategies now enabled via
[server.auth.api.jwt].enabled and [server.auth.api.mtls].enabled;
listener TLS moved to [server.listen.tls])
- docs/integrations/daytona.mdx, github.mdx (provider config now
nested under [run.sandbox.daytona] / [server.integrations.github])
- docs/human-tools/ssh-access.mdx (sandbox examples to v2)
- docs/agents/mcp.mdx (Playwright sandbox example to [run.agent.mcps])
- docs/core-concepts/models.mdx (model config and fallbacks array to
[run.model])
Canonical fabro-cli overrides and server run_manifest now emit
verbose via [cli.output].verbosity = verbose rather than the prior
run.metadata staging. No code changes beyond those Stage 4 fixes that
were already in flight.
Tighten pre-manifest cleanup by removing the old dotenv helper, reducing
legacy .env handling to warning-only path detection, and renaming internal
remote target fields from base_url to api_url.
This also updates install/server docs and CLI terminology so the codebase
reflects the current direct-run vs server-interface model more accurately.
Move secret storage, diagnostics, and repo/provider validation behind the
server API so credentials live under the server storage dir and take effect
immediately without process env mutation.
This also removes the old .env runtime path, rewires doctor/install/secret/
provider login/repo init around the server contract, and regenerates the
TypeScript client for the new endpoints.
Restructure the flat `serve` command into a nested `server start`
subcommand, following the existing namespace pattern (system prune,
repo init, etc.).

Drop the Sprites (Fly.io microVM) sandbox provider entirely. Three
providers remain: Local, Docker, and Daytona.
- Delete lib/crates/fabro-sandbox/src/sprites/ module
- Remove sprites feature flag and dep comments from Cargo.toml
- Remove sprites module declaration from lib.rs
- Update resolve_path cfg guard to daytona-only
- Delete docs/integrations/sprites.mdx and remove nav entry
- Remove Sprites rows from provider tables in docs
- Clean up SDK reference and changelog mentions

Resume now follows the same subprocess pattern as run: look up run
directory by ID prefix, validate checkpoint exists, clean stale
artifacts, reset status to Submitted, spawn _run_engine --resume, and
attach. This eliminates ~1600 lines of duplicated env/sandbox setup
from resume.rs.
Key changes:
- operations::start() and operations::resume() take run_dir instead
of Persisted, loading state from disk internally
- run_engine() builds RunOptions from RunRecord on disk, so callers
no longer extract record fields manually
- StartOptions flattened (no more nested InitOptions)
- FabroError::Precondition variant for start/resume guard checks
- _run_engine accepts --resume flag to dispatch to resume path
- operations::restore removed (no longer needed)
- Resume CLI stripped to just <RUN_ID> + --detach

New page (execution/outcomes.mdx) defines the 5 stage statuses, documents
how each handler produces them, and explains allow_partial, auto_status,
the retry loop, goal gate interaction, and outcome in edge conditions.
Existing pages updated: added missing `skipped` status to outcome key
descriptions, improved `goal_gate`/`auto_status` descriptions in the
dot-language reference, added `allow_partial` to the attributes table,
and added cross-links from failures.mdx and transitions.mdx.

Roadmap: replace placeholder items with current shipped/building/planned
features. Use real dates for sorting instead of manual sortOrder. Fix
UTC timezone rendering for date display.
Terminology: replace all standalone "DOT" references with "Graphviz" or
"Graphviz DOT" across docs, marketing, README, AGENTS.md, and OpenAPI
spec. Changelogs left unchanged as historical records.

Regenerate 2026-03-10 changelog with full commit set (installer, devcontainer
support, arc pr subcommands, --no-dotenv removal). Add 2026-03-11 changelog

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).

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
in Mintlify (Shiki). Full digraph blocks get a title derived from the workflow
name (e.g. title="hello.dot").
