Create run-owned sandbox lifecycle operations so terminal runs stop by default, resumes attach and start persisted sandboxes, and run deletion deletes or hands off provider resources according to preserve settings.
Replace the loose interview answer request payload with a discriminated OpenAPI union so generated clients enforce the wire contract. Surface structured HTTP error details in the web client and update browser, CLI, and server answer submission paths to use the typed variants.
Emit agent.interrupt.injected when run interrupts reach active agent sessions, persist the stage/session fields, and refresh/render those rows in the Transcript tab.
Route command stderr into stdout at execution time and expose a single output log across events, projections, API clients, and the web UI. Keep replay compatibility for older command.completed events that still contain split stdout/stderr fields.
Compute cheap diff stats on checkpoint and terminal events, roll them into run summaries, and use them for the Files Changed tab badge without fetching full file diffs.
Add a `last_event_at` timestamp to RunProjection (set in apply_event so
every event ticks the field) and surface it through RunSummary and the
RunListItem board response. Backed by an OpenAPI extension so both the
Rust and TypeScript clients pick up the new optional field.
In the web UI, the run-detail header gains a "Last activity Xm ago"
badge next to the elapsed-time chip, driven by a 30-second ticker so the
relative time stays current between event refreshes.
The fabro-server tests.rs hunk is incidental rustfmt drift surfaced by
running `cargo fmt --all` over the workspace; including it keeps CI's
fmt-check green.

## Summary
This makes the advertised mid-run steering path real: users can send
append or interrupt steering messages through the API, CLI, and web UI,
and the worker delivers them to live API-mode agent sessions or buffers
them for the next session. The change adds the control protocol, session
interrupt machinery, workflow hub, server route/OpenAPI/client updates,
and UI feedback needed for the whole path.
### Plan Summary
- Add `SteerKind`/`run.steer` wire protocol and `POST /runs/{id}/steer`
- Deliver steers through subprocess JSONL or the in-process
`SteeringHub`
- Support append and interrupt behavior in agent sessions, with bounded
buffering and events
- Expose steering in the CLI/web UI and surface SSE toasts
## Flow
```mermaid
flowchart TB
UI["CLI / Web UI"] --> API["POST /runs/{id}/steer"]
API -->|"subprocess transport"| Control["Worker control JSONL"]
API -->|"in-process transport"| Hub["SteeringHub"]
Control --> Hub
Hub -->|"active API sessions"| Session["SessionControlHandle"]
Hub -->|"no active session"| Pending["Pending buffer"]
Pending -->|"first future API session"| Session
Session --> Agent["Session round loop"]
Agent --> Events["RunEvent stream"]
Events --> UI
```
## What changed and why
- Agent sessions now expose a lightweight `SessionControlHandle`, drain
steering at the top of each round, and use a replaceable round
cancellation token for interrupts. LLM waits are cancelled promptly,
while tool execution observes cancellation cooperatively so every
committed `tool_use` still gets a matching `tool_result`.
- `SteeringHub` owns active API session registration, broadcast
delivery, pending buffering, FIFO queue caps, and steering
lifecycle/drop events. A completion coordinator closes the
final-response race without introducing a workflow dependency into the
agent crate.
- The server route replaces the 501 stub, validates run state and
best-effort CLI-only steerability, and forwards through either
subprocess control JSONL or the in-process hub. OpenAPI and generated
clients now include the request type.
- The CLI and web UI can send append or interrupt steers. Run detail and
board views open the new composer, and shared SSE subscriptions now
support per-subscriber event callbacks so invalidation and steering
toasts can coexist on one EventSource.
## Review notes
- Steering actors stay on top-level `RunEvent.actor`; event props only
carry steering kind/drop metadata.
- Buffered steers replay as append messages to the first API session
that registers after an empty-active period. Per-stage targeting remains
out of scope.
- CLI-mode agent stages are still not steerable; the server returns a
best-effort 409 when all active agent stages are CLI-mode, while the
worker hub remains the authoritative safety net.
- No persistence or schema migration is required; active and pending
steering state is in memory.
- New tests focus on protocol round-trips, hub buffering/bounds, session
steering-loop behavior, SSE fanout, and basic server rejection paths.

## Summary
Token scopes describe what *a run* is authorized to do, not server
identity. Today they live under
`[server.integrations.github.permissions]`, which can't be overridden by
`workflow.toml` / `project.toml` (server keys are stripped from
per-workflow layers) — so projects and workflows can't tighten or relax
permissions despite the docs already advertising a per-run config. This
PR moves them under `[run.integrations.github.permissions]`, where the
standard layer-merge (workflow > project > user > defaults) Just Works.
Greenfield, no migration shim.
## What changed
- **New layer/resolved types** in `fabro-config` and `fabro-types`:
`RunIntegrationsLayer`, `RunIntegrationsGithubLayer`, and resolved
counterparts. `permissions` becomes a flat `HashMap<String,
InterpString>` post-resolve; empty = no token requested.
- **Server schema**: `permissions` removed from `GithubIntegrationLayer`
/ `GithubIntegrationSettings`. `deny_unknown_fields` rejects the stale
path.
- **Bundled `workflow.toml` parsing** (`run_manifest.rs`): now goes
through `SettingsLayer` via the new `parse_run_layer_from_settings_toml`
helper, so stale `[server.integrations.github.permissions]` errors
instead of being silently dropped by the old `toml::Table` lift-out.
- **Consumers updated**: server preflight, run launch path, and the CLI
worker (`runner.rs`) all read run-level permissions. CLI worker
previously hardcoded `HashMap::new()` — runs launched via the local CLI
path were getting no `GITHUB_TOKEN` regardless of TOML.
- **Shared helpers** on `RunIntegrationsGithubSettings`:
`is_token_requested()` and `resolve_permissions(lookup)` so server and
CLI don't drift.
- **OpenAPI + TS client** regenerated; new `RunIntegrationsSettings` /
`RunIntegrationsGithubSettings` schemas added, `permissions` removed
from `GithubIntegrationSettings`.
- **Repo workflows + docs** rewritten to the new path. Docs gain a
security-model note (boundary = installation grants; no Fabro-side cap).
## Key design decision: hand-rolled `Combine` for
`RunIntegrationsGithubLayer`
`ReplaceMap`'s "empty inherits from below" semantics (`maps.rs:76-80`)
are wrong here — we want `permissions = {}` in a higher layer to act as
an explicit clear. So the layer field is `Option<HashMap<...>>` with
hand-rolled `Combine`:
| Higher layer | Lower layer | Result |
|---|---|---|
| `None` | anything | lower (inherit) |
| `Some(map)` | anything | `Some(map)` (full replace, including
`Some({})` = clear) |
Not derived: the blanket `Option<T: Combine>` impl would recurse into
the inner `HashMap` and reintroduce empty-fallback. Documented inline in
`layers/run.rs`.
`InterpString` is preserved through resolve and only flattened to
`String` at the start-services boundary, matching the existing pattern.
### Plan Summary
- New `[run.integrations.github.permissions]` layer + resolved types;
remove from server side.
- Hand-rolled `Combine` so empty-wins-as-clear; no change to
`ReplaceMap` semantics for other consumers.
- Strict `SettingsLayer` parse for bundled `workflow.toml` so stale
schema errors loudly.
- Both server and CLI worker paths read run-level permissions via shared
helpers.
- OpenAPI + TS client regenerated; parity test added.
- Repo workflow TOMLs and `integrations/github.mdx` rewritten.

### Summary
Billing and stage lists now use the event-sourced `RunProjection` as
their source of truth, so running and retrying stages appear immediately
and runtimes keep advancing in the UI. This removes the checkpoint
completed-node bypass that hid in-flight work and froze totals until the
next server response.
### Plan Summary
- Store stage `started_at`, terminal `duration_ms`, server-internal
`usage`, and lifecycle `state` on `StageProjection`.
- Populate those fields from stage lifecycle events, including retry
transitions and per-attempt reset on new starts.
- Render `/runs/{id}/stages` and `/runs/{id}/billing` from
`RunProjection.iter_stages()`.
- Expose the new API/client fields and tick in-flight billing runtimes
on the web UI.
```mermaid
flowchart TB
Events["Stage lifecycle events"] --> Projection["RunProjection StageProjection"]
Projection --> StagesAPI["GET /runs/{id}/stages"]
Projection --> BillingAPI["GET /runs/{id}/billing"]
StagesAPI --> StageUI["Stage sidebar/stages view"]
BillingAPI --> BillingUI["Billing tab live totals"]
```
### Key decisions
Retry and revisit handling stays one row per node id: latest visit data
wins, while first-seen event sequence keeps ordering stable with
finalize output. `state` is stored rather than derived so `Retrying` is
representable, and old serialized projections still work through the
`effective_state()` fallback. Billing `usage` remains server-internal
and is skipped on the wire; public schemas only expose the fields needed
by `/stages`, `/billing`, and the frontend live timer.
Added focused reducer, server retry/revisit, API round-trip, billing UI,
and event invalidation coverage.

Include completed stages without LLM usage in run billing responses so command-only runs still show runtime rows. Keep token and model aggregates scoped to billed LLM usage, and render placeholder values in the web billing table.
So that CLI and other API consumers can surface a clickable link to the
run's web UI page instead of guessing route shapes or probing settings.
The server populates `web_url` from `server.web.enabled` and
`server.web.url`, returns it on `RunStatusResponse` (create plus all
lifecycle transitions), and persists it on the `run.created` event so
attach replays the same link without re-deriving it.
CLI: prints `Web UI: <url>` as a run-header info line, driven off the
replayed event so fresh runs and `attach` share one code path. Absent
when the UI is disabled.

Represent command termination explicitly across sandbox results, events,
run projections, API types, and the run stage UI. This removes the fake
-1 exit code path for timeout/cancel and lets consumers tell cancelled
commands apart from timed-out commands.
Persist command stdout/stderr through scratch logs and finalized CAS refs, expose byte-offset tailing through the API, and render separate streaming panels in the web run view.
Resolve command output blob refs for execution-time consumers such as edge routing and retros, and make Docker streaming timeout/cancel drain output before returning.
Add configured to the model API contract and server responses so clients can see whether provider credential material exists before testing. Use that signal in bulk model tests to skip unconfigured providers before printing progress and treat post-list skips as race failures.
Eliminate four parallel-type duplications between fabro-api generated
DTOs and fabro-types canonical types. The wire shape is owned by
OpenAPI; canonical types are reused via fabro-api/build.rs
with_replacement so the adapter functions and silent unwrap_or_default
defaults disappear.
- SecretType moves to fabro-types (was fabro-vault); deletes
secret_type_from_api adapter.
- DiffLineStats renamed to DiffStats, moved to fabro-types, switched
u64 -> i64 to match the OpenAPI integer; deletes line_stats_to_api.
- ManifestPreRunPushOutcome rewritten as a oneOf+discriminator
PreRunPushOutcome over five variant schemas, deleting both
pre_run_push_outcome_from_manifest and build_manifest_push_outcome.
- ManifestGit and PreRunGitContext unify as GitContext: dirty:
DirtyStatus replaces clean: bool (preserving the Unknown state
previously truncated on the wire), sha becomes Option<String>, and
origin_url/branch fold into the unified context. RunSpec and
RunCreatedProps flatten three fields (repo_origin_url, base_branch,
pre_run_git) into a single git: Option<GitContext>.
Each replacement gets a fabro-api parity test (TypeId equality plus
JSON roundtrip) modeled on run_summary_round_trip.rs. TS client
regenerated.
Greenfield app, no production deployments — wire contract changed
directly without backwards-compat shims.

The persisted bool described user intent (\"the user opted into the
in-place execution mode\"), not a literal consequence -- SlateDB and
event-sourced checkpoints flow regardless of the flag, only git
checkpoints are skipped. Renaming aligns the name with intent and
decouples it from any future implementation that allows git
checkpoints in-place.
The fork validator still consults this bool to bail out with a clear
error before searching for git checkpoints that won't exist.
Relocate the Mintlify tree to docs/public and consolidate internal docs under docs/internal. Update build scripts, tests, CI filters, README references, and local docs skills to follow the new layout.
Add configurable server log destinations with an environment override so containers can stream foreground server logs to stdout while local installs keep file logging by default. Validate configured log filters at load time and reject stdout logging for daemon mode.
Reuse the existing merge strategy type across CLI/API/GitHub paths, consolidate repeated PR command setup, and serialize server-side PR creation per run to avoid duplicate external work.
Merge origin's fabro-config types boundary refactor (dense settings
migration: WorkflowSettings/UserSettings/ServerSettings moved to
fabro-types; SettingsLayer made pub(crate) inside fabro-config) into
local PR-refactor branch.
Conflict resolution intent:
- lib/crates/fabro-cli/src/commands/pr/{create,mod}.rs — kept HEAD's
server-side PR command implementations; origin still carried the
pre-refactor client-side helpers (build_github_credentials,
load_pr_record, branch_exists pre-check) that local commits had
already migrated to the server.
- lib/crates/fabro-cli/src/user_config.rs — took origin's resolution
(load_resolved_settings_from_toml + storage_dir_from_document tests),
which implements the same dead-storage_dir-wrapper cleanup local had
done via local_server::storage_dir.
- lib/crates/fabro-server/src/server.rs — kept HEAD's PullRequestRecord
import alongside origin's added ServerSettings; rewrote test helpers
github_token_settings + create_github_token_app_state to use origin's
ServerSettingsBuilder + AppStateConfig dense-settings shape (replaces
HEAD's parse_settings_layer + Arc<RwLock<SettingsLayer>>); switched
RunSpec.settings fixture from SettingsLayer::default() to
WorkflowSettings::default() per origin's RunSpec retype.
- Suppressed dead_code on CommandContext::storage_dir() and
::server_settings() (added by origin for use by client-side PR
commands that no longer exist after local's server-side migration);
gated load_resolved_settings_from_toml on cfg(test).
Verified post-merge: workspace fmt clean, clippy --all-targets
-D warnings clean, cargo nextest run --workspace 4587 passed,
182 skipped.
Move PullRequestDetail, PullRequestGithubDetail, PullRequestUser,
PullRequestRef, and MergeMethod into fabro-types. Register them as
fabro-api with_replacement targets so the OpenAPI client and the server
share one canonical type per concept.
PullRequestDetail composes a stored PullRequestRecord with a flattened
PullRequestGithubDetail mirroring GitHub's REST payload, removing the
hand-rolled pull_request_detail_json builder in the server. Change the
PullRequestRef wire field from `ref_name` to `ref` so the same Rust
type round-trips through both GitHub and our API without aliases.
The server now uses fabro_api::types::{Create,Merge,Close}* directly,
deleting the hand-defined request/response shadows and the
`body.method.parse::<...>()` call (the typed MergeMethod enum drives
deserialization). Drops fabro-cli's `i64::try_from(record.number)`
panic path and the AutoMergeMethod enum (replaced by MergeMethod).

Collapse the five near-identical settings.with_replacement calls in
fabro-api/build.rs into a single data-driven table loop, flatten the
status round-trip test loops into per-variant assertions (dropping
redundant duplicate assertions against both API and domain variants
since TypeId already proves they're the same type), and tighten the
unknown-stage-status tracing message so it describes the event rather
than narrating the fallback rationale.

The CLI façade is the primary type callers reach for, so it deserves
the bare `Client` name (per `reqwest::Client`, `hyper::Client`
convention). The raw generated HTTP binding is secondary and is more
accurately named `ApiClient`. "Store" in `ServerStoreClient` was
leftover from the SlateDB-ownership refactor and no longer describes
the type.

Enable clippy's unwrap_used lint at warn level, document the long-term
policy carveouts for tests and LockResult, and localize the generated
OpenAPI client exemption so the remaining warning surface is real repo
code.
Enable clippy::allow_attributes_without_reason at the workspace level.
Add concise, callsite-specific reasons to existing allow attributes, including generated code paths.
