After each pipeline run, auto-derive stats from the checkpoint (stages,
retries, cost, files touched) then run an Opus agent session that
explores progress.ndjson to produce qualitative analysis: smoothness
rating, intent, outcome, learnings, friction points, and open items.
Backend:
- retro.rs: data model, save/load, derive_retro(), extract_stage_durations()
- retro_agent.rs: post-pipeline agent session with submit_retro tool
- cli/run.rs: hook retro generation after final.json, before engine_result?
- server.rs: GET /pipelines/{id}/retro endpoint, auto-derive on completion
Frontend:
- data/retros.ts: TS types + mock data + smoothness color config
- routes/retros.tsx: list page with smoothness badges
- routes/run-retro.tsx: detail view (stats, intent, stages, learnings)
- routes.ts + run-detail.tsx: wire up retro route and tab

Parallel branches now get isolated git worktrees so concurrent file
writes don't collide. Works across Local, Docker (bind-mount), and
Daytona (remote exec_command) environments.
Key changes:
- git.rs: add create_branch_at() and merge_ff_only() helpers
- engine.rs: add GitState struct, remote worktree helpers
(git_create_branch_at_remote, git_add_worktree_remote, etc.)
- handler/mod.rs: add git_state field to EngineServices (RwLock)
- handler/parallel.rs: WorktreeEnv wrapper, per-branch worktree
setup/teardown, checkpoint commits per branch, ff-merge winner
before returning to engine
- handler/fan_in.rs: ff-merge to winner's HEAD, set best_head_sha
- E2E tests for Host (local) and Daytona (remote) modes
When git_state is None, behavior is unchanged.

LLM-authored output can set failure_class to non-canonical strings like
"retryable", "transient", or "permanent". Expand FromStr to accept 30+
aliases with case-insensitive trimmed matching, matching Kilroy's
normalizedFailureClass(). Unknown values fail-closed to Deterministic
instead of returning Err.

Absolute `cd` paths in shell commands (script/tool_command attributes) silently
override the engine's worktree CWD, breaking portability across machines,
containers, and worktrees. Ported from kilroy (danshapiro/kilroy d9c1fec).

- Fix 4 test failures: add unconditional fallback edges to branching.dot
and conditions.dot to satisfy all_conditional_edges validation rule
- Fix clippy await_holding_lock: scope MutexGuard before await in
daytona_integration.rs
- Fix clippy unnecessary_get_then_check: use contains_key in script.rs
- Fix clippy expect_fun_call: use unwrap_or_else in integration.rs
- Run cargo fmt across entire workspace

Add 8 missing transient_infra patterns (crates.io registry, toolchain,
cross-device link errors), 2 structural hints (write_scope_violation
variants), and reorder heuristic priority to check transient_infra
before budget_exhausted to match Kilroy's classification behavior.

Raise the Anthropic adapter fallback from 4096 to 16384 to prevent
truncation of large tool call JSON when the model isn't in the catalog.
Add max_tokens as a configurable DOT node attribute that flows through
SessionConfig to LLM requests, following the same pattern as
reasoning_effort. Priority: node attribute > catalog > provider default.
Ported from kilroy (danshapiro/kilroy) commits 99a5cd7 and 78fadad.

Extract hint patterns into const arrays (TRANSIENT_INFRA_HINTS,
BUDGET_EXHAUSTED_HINTS, STRUCTURAL_HINTS) and add 28 new patterns
from Kilroy to prevent transient/budget failures from misclassifying
as deterministic. Add comprehensive regression test per pattern plus
count-guard tests to catch accidental additions/removals.

Move HTTP server (Axum routes, JWT auth, serve CLI command, server
config) from arc-workflows into a dedicated arc-api crate. This
improves separation — arc-workflows is a pipeline engine library,
not a web server.
- Create crates/arc-api with server.rs, jwt_auth.rs, serve.rs,
server_config.rs and their integration tests
- Remove server feature flag and optional deps from arc-workflows
- Update arc-cli to depend on arc-api for ServeArgs and serve_command

Introduces server_config.rs with a TOML-based ServerConfig struct
(version + url) following the same patterns as TaskConfig.
