## What
Makes the run-detail stage sidebar (shown on the Overview and Stages
tabs) collapsible with a slide animation.
- A toggle button slides the panel between full width (`w-56`) and an
icon-only rail (`w-12`), animating `width` over 300ms with the same
easing as the Ask Fabro panel.
- When collapsed, **stage status icons stay visible** — green check /
red X / spinning teal for running — so run progress is still scannable
at a glance. Workflow links (Graph Source, Run Logs, etc.) collapse to
icons too so they remain reachable.
- Labels and durations become `sr-only` with `title` tooltips for hover.
- The open/closed choice persists to `localStorage`
(`fabro:stage-sidebar-collapsed`), carrying across the Overview and
Stages tabs and reloads.
## Layout
- The collapse toggle is inline with the `STAGES` heading row (or
`WORKFLOW` when a run has no stages yet), so it doesn't push the stage
list down.
- The stage sidebar's top padding on the Stages tab was reduced (`pt-6`
→ `pt-3`) so the heading aligns with the adjacent content column and
sits closer to the tab nav.
## Notes
Self-contained in `StageSidebar` — `run-overview.tsx` and
`run-stages.tsx` render it inside flex layouts that already track its
width, so the slide works in both with no parent changes (aside from the
padding tweak).
Verified: `tsc` typecheck passes; `stage-sidebar` lib tests pass
(10/10).

## Summary
Adds the run-backed API surface needed for a real Ask Fabro sidebar: run
readiness metadata, detailed session projections, session-scoped event
listing/attach streaming, and turn control that exposes durable turn IDs
and machine-readable failures.
## What Changed
- Extended the OpenAPI contract and regenerated Rust/TypeScript clients
for `Run.ask_fabro`, `SessionDetail`, `SessionTurn`, paginated run
sessions, session event APIs, and optional client-supplied `turn_id`
values.
- Updated `fabro-types` and `fabro-store` so durable `run.session.*`
events project active turn state, transcript messages, and the latest
owning run event sequence.
- Implemented server routing for session details, `/events`, `/attach`,
turn conflict headers, typed turn failure codes, and cheap run readiness
decoration across run responses.
- Added browser helpers for POST turn streaming and session attach SSE
parsing, plus an exported generated `sessionsApi`.

## Summary
Ask Fabro sessions are now run-bound instead of standalone. Sessions are
created under their owning run, then accessed by flat session ID routes,
with durable state projected from the run event stream rather than a
separate session store.
## Changes
- Move session creation/listing to `POST/GET /api/v1/runs/{id}/sessions`
while keeping flat session reads, turns, interrupts, and event streams
under `/api/v1/sessions/{id}/...`.
- Add typed `run.session.*` events, ULID-backed session/turn IDs,
read-only default permissions, and a rebuildable SlateDB `session_id ->
run_id` index.
- Remove the old file-backed session store and wire the server, runtime,
Rust client, generated API crates, and TypeScript client around run
event projections.
- Replace the old top-level CLI session command with `fabro run ask` for
chatting with a run.
- Regenerate the TypeScript API client; this also catches up existing
generated models for Pair/run event detail schemas already present in
the OpenAPI spec.

## Summary
Adds the server-side run pairing surface for joining one active API-mode
agent session, sending pair messages, reading a compact transcript, and
ending pairing explicitly before workflow release continues.
This PR wires the feature end to end:
- adds OpenAPI paths and shared `fabro-types` DTOs for pair lifecycle,
messages, transcript entries, and run event details
- adds typed `RunEvent` variants for pair lifecycle and pair-scoped
user/system messages
- extends the workflow steering hub and agent session drain path with
typed pair control items, single-target validation, pair parking, and
pair end/resume behavior
- extends worker JSONL control and server transports for pair
start/message/end while preserving existing
steer/interrupt/answer/cancel behavior
- adds Axum handlers for `/api/v1/runs/{id}/pair`, pair messages, pair
transcript, and `/api/v1/runs/{id}/events/{seq}`
- adds `fabro-client` helpers for the new endpoints
## Notes
The subprocess path does not add a bidirectional worker ack channel in
this PR. Instead, the HTTP pair handlers only return lifecycle/message
success after the corresponding durable runtime event is observed, so
mpsc enqueue success alone is not treated as API success.
The plan checklist in
`docs/superpowers/plans/2026-05-18-server-side-run-pairing-api-events.md`
is included with that distinction left visible.

## Summary
The run Overview tab's "Created by" cell rendered every user as a
colored circle with the first letter of their login. Reviewers and run
owners expected the same GitHub avatar shown on `/profile` and in the
top-right nav. The cell only had `login` to work with — the
`PrincipalUser` schema carried no avatar URL.
This threads an optional `avatar_url` through `UserPrincipal`
end-to-end: schema, server auth, and frontend. The avatar is captured at
action time from the request's auth context and persisted with the run's
`created_by` principal — a point-in-time snapshot, the same pattern as
audit logs and chat apps.
## What changed
- **`fabro-types`** — `UserPrincipal` gains `avatar_url: Option<String>`
with `#[serde(default, skip_serializing_if)]`, plus a
`Principal::user_with_avatar` constructor. The existing
`Principal::user` constructor is unchanged (sets `None`), so test
fixtures and CLI/replay call sites need no edits.
- **OpenAPI** — `PrincipalUser` gains an optional nullable `avatar_url`;
Rust (progenitor) and TypeScript clients regenerated.
- **`fabro-server`** — `auth_context_from_session` (cookie auth) and
`classify_user_token` (JWT auth) populate the principal's avatar from
the session/JWT, treating an empty string as `None`.
- **`fabro-web`** — the `run-summary-panel` "Created by" cell renders an
`<img>` when `avatar_url` is present, falling back to the initial circle
otherwise.
## Compatibility
The field is optional with serde defaults, so old persisted runs and
`RunEvent.actor` payloads deserialize unchanged — they show the
initial-circle fallback. No migration or backfill.
## Known gap
CLI-initiated runs (`fabro run ...`) still show the initial circle: the
CLI auth flow hardcodes an empty `avatar_url` in the JWT subject
(`cli_flow.rs:508`). Wiring the avatar through CLI login
(`~/.fabro/auth.json`, JWT claims, refresh-token chain) is a deliberate
follow-up. Web-initiated runs get the avatar today.
## Test plan
- `cargo nextest run --workspace` — 5,832 tests pass, including new
`principal.rs` and `principal_round_trip.rs` cases covering avatar
serialization and legacy-JSON (no-field) deserialization.
- `cd apps/fabro-web && bun test run-summary-panel` — 13 tests pass,
including a new case asserting the `<img>` renders with the avatar src.
- `bun run typecheck`, `cargo +nightly-2026-04-14 fmt --check --all`,
and `clippy --workspace --all-targets -- -D warnings` all clean.
- Manual: restart `fabro server`, create a run from the web UI, confirm
the real avatar renders on the Overview tab; confirm an older run falls
back to the initial circle.

## Summary
Operators had no UI surface to see which LLM providers their Fabro
server has configured — provider state was only inferable indirectly via
the per-model `configured` flag on `GET /api/v1/models`. This adds a
dedicated **Models** settings tab backed by a new providers endpoint.
- **`fabro_model::Provider`** — a public projection of the internal
`CatalogProvider` that *structurally* excludes credential-bearing fields
(`auth`, `extra_headers`, `billing_policy`, `agent_profile`). Reused by
the generated API client via progenitor `with_replacement`, mirroring
the existing `Model` pattern — no parallel API DTO.
- **`GET /api/v1/providers`** — lists catalog providers with effective
config and a `configured` status stamped per request from
`ready_llm_provider_ids()`. Sorted by the catalog's existing
`provider_order`. No write endpoints.
- **`/settings/models` web page** — new route + nav entry
(`CpuChipIcon`, between Integrations and Security) rendering each
provider with model count, default model, configured status, and a "Get
API key" link for unconfigured providers.
## Key decisions
- Provider sort: reuse catalog `provider_order` (priority desc, id asc)
— zero extra code.
- `adapter` is hidden in the UI row (noisy for first-party providers);
the OpenAPI `adapter` field is pinned to an enum matching the closed
`AdapterKind` type.
- `configured` reflects credential resolution **at the time of the
response**, not a frozen startup snapshot — doc/spec wording corrected
to match.
## Testing
- `fabro-model`: `From<&CatalogProvider>` + serde `skip_serializing_if`
unit tests.
- `fabro-api`: `Provider` type-identity + JSON-parity tests, including
the required/optional field split.
- `fabro-server`: handler tests for configured vs unconfigured
providers, exact `model_count`/`default_model` against catalog truth,
and credential-omission (asserts internal field names *and* the injected
credential value never reach the wire).
- OpenAPI route conformance test covers `GET /api/v1/providers`.
- `cargo build --workspace`, `fmt --check`, `clippy -D warnings` clean;
935 Rust tests pass; web `tsc` typecheck passes.
- Reviewed via a 10-persona `ce:review` (autofix) — no P0/P1 in shipped
code; 8 safe fixes applied.
Not done: manual UI screenshots — the `apps/fabro-web` build is blocked
in this environment by an unrelated missing `@assistant-ui/react`
dependency. Run `bun install` in `apps/fabro-web` to verify
`/settings/models` manually.
## Post-Deploy Monitoring & Validation
- **What to watch:** request logs for `GET /api/v1/providers` — expect
`200`s for authenticated users, `401` for unauthenticated. The handler
resolves LLM credentials per request via `ready_llm_provider_ids()` (the
same path the existing `list_models` handler already uses).
- **Healthy signals:** `/settings/models` renders the provider list;
`configured` matches each provider's actual credential state; no
credential strings appear in any response body or log line.
- **Failure signals / rollback trigger:** any provider object in the
response containing `auth`, `extra_headers`, or a raw key/token value →
roll back immediately (the projection type makes this structurally
impossible, but treat any occurrence as P0). 5xx spikes on the new
route.
- **Validation window / owner:** first 24h after deploy, owned by the
deploying engineer. Pre-existing note (not introduced here): credential
resolution can refresh OAuth tokens and write the vault as a side effect
of this read — shared with `list_models`; flagged for a future caching
pass.

When Fabro creates a detached run through the server, the resulting run
metadata should still read like something a human can trust at a glance.
Before this change, those runs could persist with
`settings.project.name` and `settings.workflow.name` left `null` even
though Fabro already had enough local context to infer them. That made
`inspect` output look half-populated and made it harder to tell whether
the saved run state was complete.
This fixes that trust gap in the server-backed manifest flow.
## Summary
- backfill missing manifest-backed project and workflow names during
server run preparation
- prefer explicit `[workflow].name` from bundled `workflow.toml`, then
fall back to graph name or workflow slug
- cover both manifest preparation and persisted run-state behavior with
server tests

## Summary
- `POST /api/v1/sessions` now requires `permissions` as a typed enum
(`read-only` | `read-write` | `full`) instead of accepting an optional
plain string.
- Removes the silent fallback at `sessions.rs:906-911` where unknown
values (e.g. `"readonly"`) were coerced to `read-write` — a real
security footgun: a client trying to lock the agent down would get write
access instead.
- Invalid or missing values are now rejected by axum's `Json` extractor
with `422 Unprocessable Entity`.
## Approach
- New `PermissionLevel` OpenAPI schema (`type: string, enum: [...]`).
- Moves `PermissionLevel` from `fabro_agent::cli` to
`fabro_types::session` so `fabro-api` can `with_replacement` it without
a circular dep. `fabro_agent::cli::PermissionLevel` remains as a `pub
use` re-export so existing call sites keep working.
- `SessionRecord.permissions` becomes required and non-nullable for
coherence — every created session has a concrete level.
- `build_tool_approval` in the server takes `PermissionLevel` directly;
the string-match fallback is deleted.
- CLI's `session_permissions` returns a concrete `PermissionLevel`
(defaults to `read-write` when neither flag nor settings provide one)
and is sent explicitly on every request.
## Scope notes
Confirmed out of scope and not addressed here:
- Mid-session model/permission switching
- Interactive tool approval / HITL
## Breaking change
The `permissions` field is now required on `CreateSessionRequest` and
non-nullable on `SessionRecord`. Existing on-disk session records
persisted with `"permissions": null` will fail to deserialize.
Acceptable per project policy (no migration); local dev users may need
to clear `~/.fabro/storage/sessions/` once.

## Summary
- Surfaces parent/child run relationships in the web UI as a new
**Children** tab between Files Changed and Sandbox on `/runs/:id`.
- Backend exposes a new `children_count` field on the `Run` summary,
computed on read from the existing
`RunProjectionCacheState.children_by_parent` index — accurate without an
extra query.
- Frontend reuses the compact-table `RunRow` from `/runs` (now exported)
so the children list matches the existing list-view at a glance.
- Tab always shows, with a zero state when there are no children.
Refresh button (icon-only, matching the Files Changed pattern)
re-fetches both the list and the parent detail so the count badge
updates with the list.
## Screenshots

`BoardColumn`, `WorkflowSettings`, SWR `Key`, and `SteerRunRequest`
names directly across Rust and web code.
- Remove legacy PR/event deserialization compatibility for old PR
records and command output fields, with tests updated to reject stale
wire shapes.
- Drop obsolete workflow aliases for `agent_loop`, `one_shot`,
`codergen_mode`, and `stack.child_dotfile`, then update docs and tests

## Summary
Adds orchestration-only parent links between runs without merging them
into fork or rewind lineage. Runs can now be created under a parent,
linked to a different parent, or unlinked through event-sourced
mutations that rebuild summaries and projections from the run event
stream.
## Changes
- Adds optional `parent_id` to run manifests, public run summaries, run
projections, `run.created`, OpenAPI, and the generated TypeScript API
client.
- Adds `PUT /api/v1/runs/{id}/parent` and `DELETE
/api/v1/runs/{id}/parent` for mutable parent links across any run state,
including terminal or archived runs.
- Records `run.parent.linked` and `run.parent.unlinked` events with
actor metadata and previous/current parent IDs.
- Validates parent changes in the API path: parent must exist for new
links, self-parenting is rejected, cycles are rejected, and same-parent
or already-root operations are idempotent no-ops.
- Adds `parent_id` filtering to run listing while preserving dangling
historical parent references after parent deletion.

- Added `pull_request.linked` and `pull_request.unlinked` events,
projection replay support, and optional PR metadata fields in shared
pull request records.
- Added API, server, and client support for `PUT
/runs/{id}/pull_request` and `DELETE /runs/{id}/pull_request`; linking
accepts GitHub PR URLs, infers owner/repo/number, and captures live
GitHub title and branch metadata when available.
- Added `fabro pr link` and `fabro pr unlink`, updated `fabro pr view`,
and kept create/merge/close behavior guarded to GitHub PRs with usable
coordinates.
- Updated web UI rendering and internal event docs so stored PR links
display cleanly when live GitHub details are unavailable.

## Summary
This PR advances the catalog-driven LLM work from fabro-sh/fabro#210 by
making the resolved model catalog the source of truth for provider
registration, request control validation, and billing identity. Runs now
preserve canonical provider/model/speed identity through pricing and API
responses instead of collapsing billing around provider API aliases or
model IDs alone.
## What Changed
- Register LLM provider adapters from the resolved catalog, including
custom OpenAI-compatible providers and their credential resolution
paths.
- Validate effective model request controls, including run-level
defaults and node overrides, before dispatching LLM requests.
- Add catalog-aware billing lookup that prices canonical `ModelRef`
values, uses base model costs for standard speed, applies per-speed cost
overrides, and returns an unknown estimate instead of silently billing
zero for unsupported combinations.
- Move Anthropic Opus fast-mode pricing into the built-in catalog for
`claude-opus-4-6` and `claude-opus-4-7`.
- Thread the injected catalog and effective speed controls through
workflow billing, including API-mode and CLI-mode handlers.
- Update billing APIs, server aggregation, generated clients, and the
web billing view to expose provider/model/speed billing identity and
keep standard and fast usage in separate rows.
## Notes for Review
Billing lookup intentionally uses canonical catalog model IDs. Provider
`api_id` substitution remains limited to provider request construction,
so aliases can be used on the wire without changing billing identity.
Event conversion paths that do not have catalog access now preserve
token counts with a null dollar estimate rather than falling back to the
bootstrap catalog.

## Summary
This PR moves Fabro’s provider/model catalog toward settings-driven
provider identity by replacing the closed provider schema at the
API/auth/model boundary with `ProviderId`, then loading built-in
provider and model metadata from embedded per-provider TOML files.
The immediate result is that built-ins now use the same settings-shaped
catalog data that custom providers will use later, while request-serving
paths still keep the existing bootstrap/default catalog behavior until
the resolved-catalog plumbing lands.
## Changes
- Replaces API-facing provider enum usage with string-backed
`ProviderId`, including OpenAPI/progenitor replacements and regenerated
TypeScript client models.
- Routes model, auth, billing, CLI, server, and workflow call sites
through provider IDs where they cross product identity boundaries.
- Builds `Catalog` from settings-shaped provider/model data with
validation for adapter keys, OpenAI-compatible `base_url`, duplicate
aliases, provider defaults, disabled entries, model controls, and
per-speed cost rows.
- Replaces `catalog.json` with embedded provider TOML files under
`lib/crates/fabro-model/src/catalog/providers/`.
- Adds an explicit `fabro_model::bootstrap_catalog` hatch for
setup/install paths and extends the dev policy test to keep bootstrap
access contained.
- Preserves public training and knowledge-cutoff labels in LLM model
settings while still accepting bare TOML dates.

Use the canonical nested Run DTO directly and reject the old flat run summary JSON shape. Update store, server, CLI, and fixtures to read and produce canonical fields.
Reuse shared frontend formatting and SSE dedupe helpers, tighten typed sandbox handling, remove obsolete run DTOs, and collapse auth-session revoke into a single store operation.
Return canonical Run payloads across run list, board, create, and lifecycle endpoints. Move archive state out of RunStatus and into lifecycle metadata, split sandbox runtime from planned sandbox data, and separate static pull request records from live pull request details.
Regenerate the TypeScript API client and migrate web, CLI, server, store, workflow, and API tests to the new contract.
Replace the separate sandbox record shape with a typed RunSandbox model shared by projections, API responses, and generated clients. The public contract now uses SandboxProvider plus a non-null id and working_directory, and removes sandbox identifier/name leakage.
Fall back to procfs when ss is unavailable, report the discovery source in API metadata, and surface the sandbox install tip in the services UI. Previewable services are ordered first for clearer service selection.
Make run.created the projection anchor and require canonical run spec/status fields in API and clients.
Collapse diff/checkpoint/conclusion payloads around RunDiff and update server, CLI, workflow, store, and generated clients.
Introduces a provider-neutral SandboxDetails record (state, image,
resources, labels, timestamps) plus a normalized SandboxState enum and
the GET /api/v1/runs/{id}/sandbox operation. The fabro-api crate reuses
the fabro-types definitions through with_replacement, and a new
parity round-trip test asserts type identity and JSON shape.
Store live per-stage token counts on StageProjection, carry typed billing model identity through agent.message events, and derive billing rollups from the projection so in-flight stages can report usage before terminal events arrive.
Persist resolved run titles on creation, expose title update events, and add the run title PATCH API. Regenerate API clients and refresh web/server invalidation so title changes are reflected across run detail and board views.
Make local sandbox execution direct by removing the public worktree mode and in-place controls from CLI, config, run state, API surfaces, docs, and UI. Keep worktree support only for internal parallel-node isolation.
Project workflows now resolve from the discovered .fabro directory instead of honoring project.directory. Keep the legacy field parse-only while removing it from resolved settings and API/client shapes.
## Summary
Removes Fabro's automatic retro generation stage so workflow runs go
directly from execution to finalization and optional PR creation. This
drops the retro-specific crate, events, projection fields, config/API
knobs, and user-facing docs in favor of the existing durable run
observability surfaces.
## What Changed
- Deleted the `fabro-retro` crate and the workflow `retro` pipeline
phase, with finalization now consuming `Executed` state directly.
- Removed retro configuration and API surface area, including
`--no-retro`, `[run.execution].retros`, manifest `no_retro`,
`features.retros`, and run projection `retro*` fields.
- Retired typed `retro.*` events while keeping historical event logs
readable by deserializing retired retro event names as `Unknown`.
- Stopped appending retro sections to generated PR bodies and updated
docs, marketing copy, screenshots, and navigation to point users toward
observability/event-stream inspection.
## Testing
Not run during PR creation; this branch already contained the
implementation commit.

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.
