haiku.rag.ingester.sources was never ingester-only: one-shot client
ingestion resolves adapters through it (create_document_from_source), and
convert() now fetches through HTTPSource, so the core client imported into
the ingester package to reach them.
Move the package to haiku.rag.sources and update every import. No shims:
haiku.rag.ingester.sources is gone.
The haiku.rag.sources plugin entry-point group is unchanged, so third-party
source packages need no edit — the group name now matches the module path it
always implied.
Source unit tests move to tests/sources/. test_source_plugins.py stays in
tests/ingester/: it drives a PeriodicPoller against the job repo, so it is
plugin wiring through ingester machinery rather than a source test.
Relocate CircuitBreaker from ingester/pollers to haiku/rag/circuit_breaker
so non-ingester callers (docling-serve provider) can reuse it without
depending on the ingester package.

The jitter-before-first-sleep block was duplicated verbatim in
PeriodicPoller.run() and FSPoller._sweep_loop(). Move it to
BasePoller._stagger_start() with a named _STAGGER_FRACTION constant.
This also gives a testable seam outside the pragma-no-cover
event-loop glue methods.
The expression `str(path.stat().st_mtime_ns) if path.exists() else None`
has a TOCTOU race: the file can be deleted between exists() and stat().
The resulting FileNotFoundError propagates up to _watch_loop's except
handler, which records a breaker failure and terminates the loop — no
more push events are processed until restart.
Replace with a try/except around stat() and return early on
FileNotFoundError. The deletion event from watchfiles will handle
cleanup.
All pollers sharing the same poll_interval_s previously woke up and
swept at exactly the same moment after startup. With 10+ sources
this causes a coordinated spike in listing traffic (S3 LIST, WebDAV
PROPFIND, HTTP HEAD) every interval.
Add a random initial delay of 0-25% of the poll interval after the
first sweep, applied to both PeriodicPoller and FSPoller's sweep
loop. Subsequent sweeps run on the normal fixed interval, now
staggered across sources.
Self-contained HTML status page served from the ingester's FastAPI app.
Polls /health, /sources, /stats, /jobs?status={claimed,dead,succeeded}
every 3s from the browser and renders queue chips, sources with
last-poll/skip-reason/circuit state, active jobs with cancel, recent
failures with retry, and recently-completed feed with op badges so
DELETE rows are visually distinct from UPSERTs. Zero external deps —
single static HTML, no CDN, no fonts, no images. Works offline.
To support the dashboard:
- New /stats endpoint exposing rolling throughput (5m/30m/1h), worker
occupancy, oldest-queued age, and per-source DLQ + queue-depth
breakdowns. Each field is a single SQL aggregation against the queue.
- JobRepo gains count_succeeded_since, oldest_queued_age_seconds,
counts_by_source.
- SourceSummary gains last_skip_reason. BasePoller now records the
reason the most recent sweep attempt was skipped ("pending_work" /
"circuit_open"), cleared on the next successful poll. Closes the
gap where operators couldn't tell from /sources alone why a source
wasn't picking up new work.
Auth: dashboard route is unauthenticated (markup only). The JS attaches
the bearer to its own JSON fetches; on 401 it prompts once and stashes
the token in localStorage.
Two Logfire fixes that landed alongside:
- Drop logfire.instrument_fastapi() and the [fastapi] extra. The control
plane is polled frequently (dashboard + docker healthcheck), so every
endpoint became a span and drowned the useful traces. logfire itself
stays — pulled in transitively via pydantic-ai-slim[logfire] — so
ingester.poller.* / ingester.job / document.* spans keep emitting.
- Wrap FSPoller._handle_watch_change in an ingester.poller.watch_event
span and pass _enqueue_extra. Without this, the watchfiles callback
ran with no active context, the _otel carrier in job.extra was empty,
and the worker's ingester.job span surfaced as an orphan trace root
instead of nesting under the FS event that caused it.
