## Summary
Adds event-sourced pull request association management for runs while
preserving Fabro-created PR creation. A run can now store a current
GitHub PR association, replace it by linking another GitHub PR URL, and
remove it through an unlink event.
## What Changed
- 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.
## Testing
- `cargo +nightly-2026-04-14 fmt --check --all`
- `git diff --check`
- `cargo build -p fabro-api`
- `cargo nextest run -p fabro-types -p fabro-store -p fabro-server -p
fabro-cli`
- `bun run typecheck` in `lib/packages/fabro-api-client`
- `bun run typecheck` in `apps/fabro-web`

## Summary
Finish phase 9 of the configurable LLM provider/model work by aligning
public docs, release notes, and guardrails with the implementation
already landed in phases 0-8.
- documents settings-driven providers/models, OpenAI-compatible gateway
examples, typed `extra_headers`, model `api_id`, controls, and per-speed
costs
- adds the 2026-05-13 changelog entry and provider string migration note
- updates the internal phase plan ledger to reflect current
implementation status
- adds a workspace policy test blocking direct production
`Catalog::builtin()` usage outside catalog owner/test code
- clarifies `Provider` as a built-in compatibility enum while open-ended
identity is `ProviderId`
## Verification
- `cargo nextest run -p fabro-dev --features dev --test it policy`
- `cargo dev docs check`
- `cargo nextest run -p fabro-model -p fabro-config -p fabro-auth -p
fabro-llm`
- `cargo build --workspace`
- `cargo nextest run --workspace` (5717 passed, 182 skipped, nextest
reported 1 leaky test)
- `cargo +nightly-2026-04-14 fmt --check --all`
- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D
warnings`
- `git diff --check`
## 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.
## Verification
- `cargo build -p fabro-api`
- `cd lib/packages/fabro-api-client && bun run generate`
- `cargo +nightly-2026-04-14 fmt --check --all`
- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D
warnings`
- `ulimit -n 4096 && cargo nextest run -p fabro-model -p fabro-workflow
-p fabro-server -p fabro-api -p fabro-cli --no-fail-fast`
- `ulimit -n 4096 && cargo nextest run --workspace --no-fail-fast`
- `cd apps/fabro-web && bun run typecheck`
- `cd apps/fabro-web && bun test`
- `git diff --check`

## Summary
Implemented ACP support as a first-class Fabro backend alongside `api`
and `cli`. This adds a new `fabro-acp` crate using the official ACP Rust
crates, routes `backend=\"acp\"` for agent and prompt nodes, adds
sandbox stdio support for local/Docker/test-support paths, emits ACP
workflow events/projections, updates server steerability handling,
validation, documentation, and black-box CLI coverage.
## Test Plan
Passed strict non-live verification:
- `ulimit -n 4096 && cargo nextest run -p fabro-workflow --run-ignored
all --no-fail-fast` — 1162 passed, 0 skipped.
- `ulimit -n 4096 && cargo nextest run -p fabro-acp -p fabro-sandbox -p
fabro-workflow -p fabro-validate -p fabro-store -p fabro-server -p
fabro-cli --run-ignored all --no-fail-fast -E 'not
test(daytona_streaming_live_smoke)'` — 3125 passed.
- `cargo build --workspace` — passed.
- `ulimit -n 4096 && cargo nextest run --workspace --run-ignored all
--no-fail-fast -E 'not test(daytona_streaming_live_smoke)'` — 5666
passed.
- `cargo +nightly-2026-04-14 fmt --check --all` — passed.
- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D
warnings` — passed.
Live-environment tests skipped/excluded under explicit user override:
- `daytona_streaming_live_smoke` was excluded from final nextest runs
because it requires live Daytona infrastructure and `DAYTONA_API_KEY`.
- Confirmed with `env -u DAYTONA_API_KEY cargo test -p fabro-sandbox
--features daytona --test daytona_streaming_live
daytona_streaming_live::daytona_streaming_live_smoke -- --ignored
--exact --nocapture`: failed fast with `DAYTONA_API_KEY must be set to
run this live smoke test`.
## Summary
Adds a stdio-based Fabro MCP server so MCP clients can manage Fabro
workflow runs through the authenticated `fabro` CLI, without a separate
MCP auth flow.
## What Changed
- Adds `fabro mcp start`, `fabro mcp config`, and `fabro mcp init
<agent>` for launching and configuring the MCP server.
- Introduces a new `fabro-mcp-server` crate with run-management tools:
- `fabro_run_create`
- `fabro_run_search`
- `fabro_run_interact`
- `fabro_run_gather`
- `fabro_run_events`
- Reuses the CLI's authenticated server connection behavior, including
OAuth refresh, dev-token/local-server handling, explicit server targets,
proxy behavior, and stdio env/cwd isolation.
- Moves shared run-manifest construction into `fabro-manifest` so CLI
runs and MCP-created runs use the same override semantics.
- Extends MCP client stdio support with configured cwd and exact
environment handling for reliable spawned-server tests.

## 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.

Keep daemon and hidden serve logs on the file destination by default, while making foreground server commands stream logs to the terminal unless the server config explicitly selects file logging.
## 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.

`thiserror`-derived `Display` does not walk `#[source]`, so `format!("{err}")`
and `format!("{err:#}")` on a typed error silently produce only the
top-level message — the same format string changes meaning when migrating
from `anyhow::Result` to a typed `Result`. Point at
`fabro_util::error::collect_chain` as the canonical helper and broaden
the test guidance to cover typed errors.

Keep sandbox exec failures structured until event emission so git push, checkpoint, notice, and retro failures can expose redacted output tails without expanding their terse error strings.
Also add log rendering that appends sanitized tail content for exec-backed errors while preserving the existing safe Display behavior.
Emit snapshot slow-path events only when Docker or Daytona actually performs image or snapshot work, replace retired completion markers with snapshot.ready, and render the lifecycle in attach/log output.
Keep fabro_workflow::event as the public facade while moving event conversion, names, redaction, sink, emitter, stored-field helpers, and StageScope into focused modules. Co-locate the existing event tests with the moved code and update the events strategy docs for the new module layout.
Add bounded redacted exec output tails to failure events while keeping tracing log-safe. Centralize tail projection on ExecResult and thread diagnostics through metadata, setup, devcontainer, and CLI install failures.
Move RunDump into fabro-dump so CLI export and retro uploads share the same hydrated run layout. Drop the legacy artifact file-ref parser, add best-effort run.log retrieval for retro, and update retro prompts/docs to use events.jsonl and checkpoints.
Move favicon, logo, logotype, and PNG icons from /public/ root to
/public/images/ so the HTTP log middleware can drop them by path
prefix. Extends the existing /assets/ skip in http_log_middleware to
cover /images/ as well, removing favicon/logo entries from the server
log without filtering by extension (which would risk muting future
extension-suffixed API routes).

Add typed metadata snapshot events around init, checkpoint, and finalize archive writes so run logs expose durable metadata timing and failures. Include snapshot accounting, CLI rendering with compatibility-notice suppression, and event documentation.
Ensure local runs use the worktree checkpoint path by default, expose source and sandbox paths in API/web surfaces, and remove dead fork/rewind push controls. Update docs for clone-based sandboxes and durable checkpoint timelines.
Add shared sandbox git validation for checkpoint paths, preserve forked run projection state, and record CLI remote mismatches explicitly. Refresh the API/client docs for durable run-store timeline and structured run specs.
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.
