A node cancelled (or lost to a crash) mid-flight and then resumed now
starts a new stage execution with the next StageId ordinal (work@2)
instead of reusing and clearing the cancelled execution's projection.
The old execution stays immutable with its own events, session, output,
timing, billing, and termination state.
Engine:
- Add a run-scoped StageExecutionTracker on RunServices with per-node
high-water marks. Ordinals are reserved after the StageStart hook
passes on the first attempt (retries reuse the reservation), ensured
at the composite checkpoint pre-step for hook-skips, and reserved in
on_terminal_reached for terminal nodes' synthetic events.
- Keep three concepts distinct: graph visit (max_visits/checkpoints,
unchanged), stage execution ordinal (the @N in StageId), and handler
attempt. The tracker is not checkpointed; the append-only stage event
history is its durable source of truth.
- resume() seeds the allocator from the run projection and computes a
node -> StageId provenance map of executions observed after the
selected checkpoint, threaded through execute_persisted_run,
RunSession, and InitOptions.
Events and projections:
- stage.started, parallel.branch.started, and checkpoint.completed
carry optional graph_visit and resumed_from_stage_id; StageProjection
stores both. Old events deserialize with None and legacy duplicate
stage.started replays keep last-attempt behavior.
- The CheckpointCompleted reducer is envelope-first: diffs and
skipped-stage synthesis attach to the exact execution StageId, an
existing Retrying projection finalizes as Skipped without losing
identity, and historical node_outcomes no longer create or collide
with newer ordinals (node_visits remains a legacy fallback).
Handlers:
- Parallel fan-out reserves child ordinals through the shared tracker,
derives worktree pass{N} from the parent's execution ordinal, and
seeds branch contexts with explicit child stage scopes so branch
lifecycle and nested handler events agree.
- Artifact capture and manager-loop child logs follow the ordinal.
API and UI:
- RunStage documents visit as the execution ordinal and adds optional
graph_visit and resumed_from_stage_id; Rust and TypeScript clients
regenerated.
- The web sidebar lists both executions chronologically; resumed stages
show a "Resumed from" link in the stage detail header and hover
popover, with the graph visit surfaced when it diverges.

- Extract a shared fetch_run_events_page helper so the three client
paging loops (full list, until, tail) no longer repeat the request/
convert/has_more skeleton; fold the tail loop's two descending-order
checks into one and drop its redundant had_events flag.
- Skip the latest-seq lookup in list_events_before_with_limit when the
caller supplies a before_seq cursor, so a cold projection cache costs
at most one full history scan per pagination session instead of one
per page.
- Remove the dead before_seq max(1) clamp and the passthrough order()
accessor from EventListParams.
- Document the CLI --tail 0 --follow seeding trick and the reader
event_seq placeholder invariant.

Adds a disabled-by-default `fireworks` provider to the built-in catalog,
served through the existing openai_compatible adapter/codec. The curated
roster covers Kimi K2.7 Code (default), Kimi K2.6, DeepSeek V4 Pro/Flash,
GLM 5.2, MiniMax M2.7, Qwen 3.7 Plus, and GPT-OSS 120B/20B (small
default + probe), with serverless pricing including cached-input rates.
All api_ids were verified live against /chat/completions (Fireworks'
GET /v1/models only returns a featured subset), and serverless responses
were confirmed to report prompt_tokens_details.cached_tokens, so cache
billing works through the existing codec path.
FIREWORKS_API_KEY is registered as an optional vault secret; provider
login, vault storage, and diagnostics probing are catalog-driven and
need no code changes. Includes catalog/install tests, two live e2e
tests, an integrations docs page, and a provider logo for the web UI.

The crate reorganization renamed lib/crates/ to lib/apps|components|foundation/.
Git followed all modified files across the rename; the only conflict was the
newly added codec/cache.rs, now placed at lib/components/fabro-llm/src/codec/cache.rs.
