Return named PR content from the builder and keep title/body fallback logic inside the builder.
Move the PR body prompt to markdown and scale prompt truncation from model context windows.
Keep PR creation resilient when generated bodies are empty by emitting a reviewer-visible skeleton body.
Make BoardColumnDefinition.id reference the existing BoardColumn schema and carry that typed contract through generated TypeScript, server responses, demo data, and the runs board UI.
Reset coordinator state when the last subscriber leaves, clear pending debounce timers on close, and keep coordinated EventSource construction owned by the coordinator while fallback subscriptions keep their local factories.
Use unknown.ts helpers in parseMessage, factor out parseLeaderPair/Triple
and per-variant parsers to remove repeated typeof guards. Extract
leaderIsFresh() for the staleness check used in three places, and make
RecentEventCache amortized O(1) by walking expired entries from the
oldest instead of scanning the whole map per event. Drop the
closeOnTerminal parameter in run-events; the fallback path computes
close at its single call site.

Prune stale election candidates as generations advance, reset coordination availability on explicit close, and keep fallback subscribers tracked so coordinator shutdown can clean them up consistently.
Stop coordinated election and leadership work when BroadcastChannel posting fails, so tabs degrade cleanly to per-subscriber fallback without stale resync or heartbeat side effects. Expand election coverage for the edge cases called out in the coordination plan.
Elect a single browser tab to own the global attach stream and broadcast run events to sibling tabs. Keep the existing per-tab EventSource path as the fallback when cross-tab coordination is unavailable.
Submitted and Queued lifecycle statuses now live in a dedicated Queued
column rendered to the left of Initializing; Starting stays in
Initializing. The column is omitted from the board when it has no items
so day-to-day boards stay compact.

Render kanban column shells while board/auth/system queries load, so the
"Your runs will appear here" panel no longer flashes before runs arrive.

This change makes bulk `fabro model test` run configured model checks
concurrently instead of serially. A new `--jobs/-j` flag (defaulting to
4, minimum 1) controls the concurrency bound; the single-model path
(`--model <MODEL>`) is unaffected. Under the hood, the serial `for` loop
over configured models is replaced with a
`futures::stream::buffer_unordered(jobs)` pipeline that clones the
shared-state `Client` per request. Completed results carry their
original list index and are sorted before rendering, so final stdout
table rows and JSON output remain in listing order regardless of which
requests finish first.
Three new integration tests verify the concurrency behavior using an
inline Axum harness with a `ConcurrencyGate` barrier. The gate holds all
in-flight requests until the expected number arrive simultaneously, then
releases them, letting tests assert `max_in_flight` exactly rather than
relying on timing. The ordering test goes further by assigning
reverse-listing response delays so the last-listed model always finishes
first; if the index sort were dropped, the JSON result order would
invert and the assertion would fail. A 15-second gate timeout ensures a
regression to serial execution surfaces as a clear `max_in_flight == 1`
failure rather than a hung test.
Existing behavior is fully preserved: unconfigured models are still
skipped without a POST, a configured model returning `skip` after
listing is still a failure, `--deep` uses the same `--jobs` value, and
`--jobs 1` reproduces the previous serial behavior for users hitting
provider rate limits.

Two follow-ups that were still costing ~1s per credential probe:
- Bumped the daytona-sdk-rust pin to fa4870f, which deletes a dead
underscore-prefixed _http_client field on Client. The field was
unused but new_with_config built a fresh reqwest::Client for it on
every call, paying the macOS proxy-discovery tax even with our
injection seam in place.
- build_api_keys_configuration was using Configuration::new() and then
overwriting cfg.client with our injected client. The Default impl
generated by openapi-generator builds a reqwest::Client::new() for
the client field eagerly, which we then threw away — another
~470ms hit per probe. Construct the Configuration as a struct
literal so the injected client is the only one we ever build.
Drops the three credential-probe tests from ~700ms to ~10ms.

Routes the two reqwest clients in the Daytona credential probe through
fabro_http (system-proxy) in production and fabro_test::test_http_client
(no_proxy) in tests, by threading an http_client parameter through
check_daytona_api_key_with and build_api_keys_configuration. Bumps the
daytona-sdk-rust pin to 314ffd9, which exposes DaytonaConfig::http_client
and ships on reqwest 0.13.
Drops the three credential-probe unit tests from >1s SLOW to ~0.5s by
skipping macOS proxy discovery on the localhost httpmock requests.

The default OpenAI model moved from gpt-5.5 back to gpt-5.4 in 38b51c4c2,
but this attach test snapshot still asserted gpt-5.5.

Use a lightweight basic probe target for preflight instead of fabricating catalog models, run configured model probes with bounded concurrency, and keep expensive model choices opt-in for defaults and live tests.
Use join_all to fan out provider probes instead of awaiting them
sequentially, and reuse fabro_util::error::collect_chain for the chain
rendering. Carry Provider through ProviderFailure instead of stringifying
it at construction.

`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.

`fabro_llm::Error`'s Display only renders the top-level message field for
`Network`/`Stream`/`Configuration`/`RequestTimeout` variants — the
`#[source]` chain is dropped. Walk the chain at the rendering boundary
so connectivity failures (DNS, connection refused, TLS) surface their
underlying cause in `fabro doctor` output.
Per docs/internal/error-handling-strategy.md, CLI surfaces should render
the full cause chain. Adds a regression test that walks `err.source()`
on a typed Network error with an inner io::Error.

`fabro doctor` now classifies LLM provider connectivity and auth probe
failures as `CheckStatus::Error` (so the command exits non-zero) and
surfaces the actual probe error text — truncated to one short line per
provider — instead of the generic "Connectivity issues with: <provider>".

Propagate OpenAI Responses SSE error and response.failed events as structured provider errors, and treat response.incomplete as a normal length finish with partial output preserved.
Also preserve those stream errors through Codex-mode complete_via_stream and add agent coverage proving quota failures do not replay the turn.
GPT-5.5 (released 2026-04-23) replaces 5.4 as the default OpenAI model.
Live integration tests confirm both new IDs respond on the OpenAI API;
they require default temperature like other reasoning models.

PR #202 shipped a new CLI subcommand without regenerating
docs/public/reference/cli.mdx, so the Generated Docs CI job failed on
push. The implement-plan workflow's verify gate had no equivalent of
`cargo dev docs check`.
Append `cargo dev docs refresh && cargo dev docs check` to verify so
the gate auto-fixes drift and surfaces real authoring errors (missing
help text, removed generated-region fences) through the fixup loop.
Also broaden the fixup prompt to cover docs errors.

The implement-plan and smoke workflows ran clippy without --all-targets,
so test, example, and bench targets were skipped. CI runs clippy with
--all-targets, so lint errors in test code passed the workflow's verify
gate but failed CI on push. Aligns the workflow lint commands with CI
and CLAUDE.md.
